[Docket Number: COE-2020-0002]
RIN 0710-AA84
Reissuance and Modification of Nationwide Permits
AGENCY: Army Corps of Engineers, DoD.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: Nationwide Permits (NWPs) authorize certain activities under
Section 404 of the Clean Water Act and Section 10 of the Rivers and
Harbors Act of 1899. The NWPs help protect the aquatic environment and
the public interest by providing incentives to reduce impacts on
jurisdictional waters and wetlands while effectively authorizing
activities that have no more than minimal individual and cumulative
adverse environmental effects. In this final rule, the Corps is
reissuing and modifying 12 existing NWPs and issuing four new NWPs. For
these 16 NWPs, the Corps is also reissuing and modifying the NWP
general conditions and definitions. The Corps is not reissuing or
modifying the remaining 40 existing NWPs or finalizing proposed new NWP
E at this time. Those 40 remaining NWPs continue to be in effect under
the January 6, 2017, final rule and the existing general conditions and
definitions in the 2017 final rule continue to apply to those permits.
DATES: These 16 NWPs, the 32 general conditions, and the associated
definitions will go into effect on March 15, 2021.

I. Background
A. General
The U.S. Army Corps of Engineers (Corps) issues nationwide permits
(NWPs) to authorize activities under Section 404 of the Clean Water Act
and Section 10 of the Rivers and Harbors Act of 1899, where those
activities will result in no more than minimal individual and
cumulative adverse
[[Page 2745]]
environmental effects. NWPs were first issued by the Corps in 1977 (42
FR 37122) to authorize categories of activities that have minimal
adverse effects on the aquatic environment, for the purpose of
streamlining the authorization process for those minor activities.
After 1977, NWPs have been issued or reissued in 1982 (47 FR 31794),
1984 (49 FR 39478), 1986 (51 FR 41206), 1991 (56 FR 59110), 1995 (60 FR
38650), 1996 (61 FR 65874), 2000 (65 FR 12818), 2002 (67 FR 2020), 2007
(72 FR 11092), 2012 (77 FR 10184), and 2017 (82 FR 1860).
Section 404(e) of the Clean Water Act provides the statutory
authority for the Secretary of the Army, after notice and opportunity
for public hearing, to issue general permits on a nationwide basis for
any category of activities involving discharges of dredged or fill
material into waters of the United States for a period of no more than
five years after the date of issuance (33 U.S.C. 1344(e)). The
Secretary's authority to issue permits has been delegated to the Chief
of Engineers and his or her designated representatives. Nationwide
permits are a type of general permit issued by the Chief of Engineers
and are designed to regulate with little, if any, delay or paperwork
certain activities in federally jurisdictional waters and wetlands,
where those activities would have no more than minimal adverse
environmental impacts (see 33 CFR 330.1(b)). The categories of
activities authorized by NWPs must be similar in nature, cause only
minimal adverse environmental effects when performed separately, and
have only minimal cumulative adverse effect on the environment (see 33
U.S.C. 1344(e)(1)). NWPs can be issued for a period of no more than 5
years (33 U.S.C. 1344(e)(2)), and the Corps has the authority to modify
or revoke the NWPs before they expire. Nationwide permits can also be
issued to authorize activities pursuant to Section 10 of the Rivers and
Harbors Act of 1899 (see 33 CFR 322.2(f)). The NWP program is designed
to provide timely authorizations for the regulated public while
protecting the Nation's aquatic resources.
The phrase ``minimal adverse environmental effects when performed
separately'' refers to the direct and indirect adverse environmental
effects caused by a specific activity authorized by an NWP. The phrase
``minimal cumulative adverse effect on the environment'' refers to the
collective direct and indirect adverse environmental effects caused by
all the activities authorized by a particular NWP during the time
period when the NWP is in effect (a period of no more than 5 years) in
a specific geographic region. These concepts are defined in paragraph 2
of section D, ``District Engineer's Decision.'' The appropriate
geographic area for assessing cumulative effects is determined by the
decision-making authority for the general permit (generally, the
district engineer).
Some NWPs include pre-construction notification (PCN) requirements.
PCNs give the Corps the opportunity to evaluate certain proposed NWP
activities on a case-by-case basis to ensure that they will cause no
more than minimal adverse environmental effects, individually and
cumulatively. Except for activities conducted by non-Federal permittees
that require PCNs under paragraph (c) of the ``Endangered Species'' and
``Historic Properties'' general conditions (general conditions 18 and
20, respectively), if the Corps district does not respond to the PCN
within 45 days of a receipt of a complete PCN, the activity is deemed
authorized by the NWP (see 33 CFR 330.1(e)(1)).
In fiscal year 2018, the average processing time for an NWP PCN was
45 days and the average processing time for a standard individual
permit was 264 days. This difference in burden can incentivize project
proponents to reduce the adverse effects of their planned activities
that would otherwise require an individual permit under Section 404 of
the Clean Water Act and/or Section 10 of the Rivers and Harbors Act of
1899, in order to qualify for NWP authorization. This reduction in
adverse effects can therefore reduce a project's impact on the Nation's
aquatic resources.
There are 38 Corps district offices and 8 Corps division offices.
The district offices administer the NWP program on a day-to-day basis
by reviewing PCNs for proposed NWP activities. The division offices
oversee district offices and are managed by division engineers.
Division engineers have the authority, after public notice and comment,
to modify, suspend, or revoke NWP authorizations on a regional basis to
take into account regional differences among aquatic resources and to
ensure that the NWPs authorize only those activities that result in no
more than minimal individual and cumulative adverse environmental
effects in a region (see 33 CFR 330.5(c)). When a Corps district
receives a PCN, the district engineer reviews the PCN and determines
whether the proposed activity will result in no more than minimal
individual and cumulative adverse environmental effects, consistent
with the criteria in paragraph 2 of section D, ``District Engineer's
Decision.'' At this point, the district engineer may add conditions to
the NWP authorization to ensure that the verified NWP activity results
in no more than minimal individual and cumulative adverse environmental
effects, consistent with processes and requirements set out in 33 CFR
330.5(d). See Section II.G for more information on regional conditions
for the NWPs.
For some NWPs, when submitting a PCN, an applicant may request a
waiver for a particular limit specified in the NWP's terms and
conditions. If the applicant requests a waiver of an NWP limit and the
district engineer determines, after coordinating with the resource
agencies under paragraph (d) of NWP general condition 32, that the
proposed NWP activity will result in no more than minimal adverse
environmental effects, the district engineer may grant such a waiver.
Following the conclusion of the district engineer's review of a PCN,
he/she prepares an official, publicly-available decision document. This
document discusses the district engineer's findings as to whether a
proposed NWP activity qualifies for NWP authorization, including
compliance with all applicable terms and conditions, and the rationale
for any waivers granted, and activity-specific conditions needed to
ensure that the activity being authorized by the NWP will have no more
than minimal individual and cumulative adverse environmental effects
and will not be contrary to the public interest (see Sec.
330.6(a)(3)(i)).
The case-by-case review of PCNs often results in district engineers
adding activity-specific conditions to NWP authorizations to ensure
that the adverse environmental effects are no more than minimal. These
can include permit conditions such as time-of-year restrictions and/or
use of best management practices and/or compensatory mitigation
requirements to offset authorized losses of jurisdictional waters and
wetlands so that the net adverse environmental effects caused by the
authorized activity are no more than minimal. Any compensatory
mitigation required for NWP activities must comply with the Corps'
compensatory mitigation regulations at 33 CFR part 332. Review of a PCN
may also result in the district engineer asserting discretionary
authority to require an individual permit from the Corps for the
proposed activity, if he or she determines, based on the information
provided in the PCN and other available information, that the adverse
environmental effects will be more than minimal, or otherwise
determines that ``sufficient concerns for the environment or any other
factor of
[[Page 2746]]
the public interest so requires'' consistent with 33 CFR 330.4(e)(2).
During the review of PCNs, district engineers assess cumulative
adverse environmental effects at an appropriate regional scale.
Cumulative effects are the result of the accumulation of direct and
indirect effects caused by multiple activities that persist over time
in a particular geographic area (MacDonald 2000), such as a watershed
or ecoregion (Gosselink and Lee 1989). Therefore, the geographic and
temporal scales for cumulative effects analysis are larger than the
analysis of the direct and indirect adverse environmental effects
caused by specific activities. For purposes of the NWP program,
cumulative effects are the result of the combined effects of activities
authorized by NWPs during the period the NWPs are in effect. The
cumulative effects are assessed against the current environmental
setting to determine whether the cumulative adverse environmental
effects are more than minimal. The district engineer uses his or her
discretion to determine the appropriate regional scale for evaluating
cumulative effects.
For the NWPs, the appropriate regional scale for evaluating
cumulative effects may be a waterbody, watershed, county, state, or a
Corps district, as appropriate. The appropriate regional scale is
dependent, in part, on where the NWP activities are occurring. For
example, for NWPs that authorizes structures and/or work in navigable
waters of the United States under Section 10 of the Rivers and Harbors
Act of 1899, the appropriate geographic region for assessing cumulative
effects may be a specific navigable waterbody. For NWPs that authorize
discharges of dredged or fill material into non-tidal jurisdictional
wetlands and streams, the appropriate geographic region for assessing
cumulative effects may be a watershed, county, state, or Corps
district. The direct individual adverse environmental effects caused by
activities authorized by NWPs are evaluated within the project
footprint, and the indirect individual adverse environmental effects
caused by activities authorized by NWPs are evaluated within the
geographic area to which those indirect effects extend.
When the district engineer reviews a PCN and determines that the
proposed activity qualifies for NWP authorization, he or she will issue
a written NWP verification to the permittee (see 33 CFR 330.6(a)(3)).
If an NWP verification includes multiple authorizations using a single
NWP (e.g., linear projects with crossings of separate and distant
waters of the United States authorized by NWPs 12 or 14) or non-linear
projects authorized with two or more different NWPs (e.g., an NWP 28
for reconfiguring an existing marina plus an NWP 19 for minor dredging
within that marina), the district engineer will evaluate the cumulative
effects of the applicable NWP authorizations within the geographic area
that she or he determines is appropriate for assessing cumulative
effects caused by activities authorized by that NWP. As discussed
above, the geographic area may be a waterbody, watershed, county,
state, Corps district, or other geographic area.
Further, the Corps' public interest review regulations at 33 CFR
320.4(a)(1) require consideration of cumulative impacts for the
issuance of DA permits. Since the required public interest review and
404(b)(1) Guidelines cumulative effects analyses are conducted by Corps
Headquarters in its decision documents for the issuance of the NWPs,
district engineers do not need to do comprehensive cumulative effects
analyses for NWP verifications. For an NWP verification, the district
engineer needs only to include a statement in the administrative record
stating whether the proposed activity to be authorized by an NWP, plus
any required mitigation, will result in no more than minimal individual
and cumulative adverse environmental effects. If the district engineer
determines, after considering mitigation, that a proposed NWP activity
will result in more than minimal cumulative adverse environmental
effects, she or he will exercise discretionary authority and require an
application for an individual permit.
There may be activities authorized by NWPs that cross more than one
Corps district or more than a single state. On May 15, 2018, the
Director of Civil Works at Corps Headquarters issued a Director's
Policy Memorandum titled: ``Designation of a Lead USACE District for
Permitting of Non-USACE Projects Crossing Multiple Districts or
States.'' \1\ This Director's Policy Memorandum identified lead
districts for states that have more than one Corps district and
established a policy for designating a lead district for activities
that require Department of the Army permits that cross district or
state boundaries. Under this policy, when the Corps receives an NWP PCN
or individual permit application for such activities, a lead Corps
district will be designated by the applicable Corps division office(s)
using the criteria in the 2018 Director's Policy Memorandum, and that
district will be responsible for serving as a single point of contact
for each permit applicant, forming a Project Delivery Team comprising
representatives of each of the affected districts, ensuring consistent
reviews by the affected districts, and taking responsibility for
identifying and resolving inconsistencies that may arise during the
review. The list of lead districts for states is also used during the
regional conditioning process for the NWPs. For that process the lead
district is responsible for coordinating the development of the
regional conditions and preparing the supplemental documents required
by 33 CFR 330.5(c)(1)(iii). The Corps requests comments on whether
there are efficiencies that can be adopted to improve the coordination
and regional conditioning processes.

B. Overview of Proposed Rule
On September 15, 2020, the Corps published in the Federal Register
(85 FR 57298) a proposed regulation to reissue with modification the
existing NWPs and associated general conditions and definitions and to
create five new NWPs (2020 Proposal). The Corps provided a 60-day
public comment period which closed on November 16, 2020. Among other
things, the Corps proposed the following: (1) To create two new NWPs to
authorize certain categories of mariculture activities (i.e., seaweed
and finfish mariculture) that are not currently authorized by NWP 48;
(2) to divide the NWP that authorizes utility line activities (NWP 12)
into three separate NWPs that address the differences in how different
utility line projects are constructed, the substances they convey, and
the different standards and best management practices that help ensure
those NWPs authorize only those activities that have no more than
minimal adverse environmental effects; (3) a new NWP which would
authorize discharges of dredged or fill material into jurisdictional
waters for the construction, expansion, and maintenance of water reuse
and reclamation facilities; and (4) to remove the 300 linear foot limit
for losses of stream bed from 10 NWPs (NWPs 21, 29, 39, 40, 42, 43, 44,
50, 51, and 52). The Corps requested comment on these and all other
aspects of the proposal.
C. Overview of This Final Rule
This final rule replaces 12 of the existing NWPs that were
published in the January 6, 2017, final rule (82 FR 1860),
specifically: NWP 12 (oil or natural gas pipeline activities; NWP 21
(surface coal mining activities); NWP 29
[[Page 2747]]
(residential developments); NWP 39 (commercial and institutional
developments); NWP 40 (agricultural activities); NWP 42 (recreational
facilities); NWP 43 (stormwater management facilities); NWP 44 (mining
activities); NWP 48 (commercial shellfish mariculture activities); NWP
50 (underground coal mining activities); NWP 51 (land-based renewable
energy generation facilities); and NWP 52 (water-based renewable energy
generation pilot projects). This final rule issues four new NWPs: NWP
55 (seaweed mariculture activities); NWP 56 (finfish mariculture
activities); NWP 57 (electric utility line and telecommunications
activities); and NWP 58 (utility line activities for water and other
substances).
For the 16 NWPs included in this final rule, the Corps is also
reissuing the general conditions and definitions, with some changes.
The Corps is not reissuing or modifying the remaining 40 NWPs included
in the 2020 Proposal or taking any action on the proposed new NWP E at
this time. The general conditions and definitions published in the
January 6, 2017, final rule (82 FR 1860) continue to apply to the 40
existing 2017 NWPs that continue to remain in effect after the final
rule for the 16 reissued and new NWPs goes into effect on March 15,
2021.
The 16 permits being finalized in this rule include permits
proposed partly in response to E.O. 13783, Promoting Energy
Independence and Economic Growth, and E.O. 13921, Promoting American
Seafood Competitiveness and Economic Growth. The Corps is also
reissuing NWPs 12 and 48 partly to address issues raised in two federal
district court decisions: United States District Court for the District
of Montana Great Falls Division's decision in Northern Plains Resource
Council, et al., v. U.S. Army Corps of Engineers, et al., (Case No. CV
19-44-GF-BMM) and the United States District Court, Western District of
Washington at Seattle's decision in the Coalition to Protect Puget
Sound Habitat v. U.S. Army Corps of Engineers et al. (Case No. C16-
0950RSL) and Center for Food Safety v. U.S. Army Corps of Engineers et
al. (Case No. C17-1209RSL).
D. Status of Existing Permits
When the Corps modifies existing NWPs, the modified NWPs replace
the prior versions of those NWPs so that there are not two sets of NWPs
in effect at the same time. Having two sets of NWPs in effect at the
same time creates regulatory uncertainty if each set of those NWPs has
different limits, requirements, and conditions because permittees may
be unclear as to which limits, requirements, and conditions apply to
their authorized activities. In addition, differences in NWP limits,
requirements, and conditions between two sets of NWPs can create
challenges for district engineers in terms of enforcement and
compliance efforts.
The Corps is modifying the expiration date for the 12 existing NWPs
(i.e., NWPs 12, 21, 29, 39, 40, 42, 43, 44, 48, 50, 51, 52) that are
issued in this final rule to March 15, 2021. The expiration date for
the 12 existing NWPs and the 4 new NWPs issued in this final rule is
five years after the date those NWPs go into effect. Activities
authorized by the 2017 NWPs currently remain authorized by those NWPs
until March 18, 2022. Under 33 CFR 330.6(a)(3)(ii), if the NWP is
reissued without modification or the activity complies with any
subsequent modification of the NWP authorization, the NWP verification
letter (i.e., the written confirmation from the district engineer that
the proposed activity is authorized by an NWP) should include a
statement that the verification will remain valid for a period of time
specified in the verification letter. The specified period of time is
usually the expiration date of the NWP. In other words, for the 2017
NWPs, if the previously verified activity continues to qualify for NWP
authorization under any of the 12 NWPs issued in this final rule, that
verification letter continues to be in effect until March 18, 2022,
unless the district engineer specified a different expiration date in
the NWP verification letter. For most activities authorized by the 2017
NWPs, where the district engineer issued an NWP verification letter,
the verification letter identified March 18, 2022, as the expiration
date. As long as the verified NWP activities continue to comply with
the terms and conditions of the 12 existing NWPs issued in this final
rule, those activities continue to be authorized by the applicable
NWP(s) until March 18, 2022, unless a district engineer modifies,
suspends, or revokes a specific NWP authorization.
Under 33 CFR 330.6(b), Corps Headquarters may modify, reissue, or
revoke the NWPs at any time. Activities that were authorized by the
2017 NWPs, but no longer qualify for authorization under any of the 12
existing NWPs that are reissued in this final rule, continue to be
authorized by the 2017 NWP(s) for 12 months as long as those activities
have commenced (i.e., are under construction) or are under contract to
commence in reliance upon an NWP prior to the date on which the NWP
expires. That authorization is contingent on the activity being
completed within twelve months of the date of an NWP's expiration,
modification, or revocation, unless discretionary authority has been
exercised by a division or district engineer on a case-by-case basis to
modify, suspend, or revoke the authorization in accordance with 33 CFR
330.4(e) and 33 CFR 330.5(c) or (d). This provision applies to
activities that were previously verified by the district engineer as
qualifying for NWP authorization, but no longer qualify for NWP
authorization under the modified or reissued NWP.
The 16 NWPs issued in this final rule go into effect on March 15,
2021. The 2017 versions of the 12 NWPs reissued in this final rule
expire on March 15, 2021. The 12 existing NWPs and 4 new NWPs issued in
this final rule expire five years after March 15, 2021.
E. Nationwide Permit Verifications
Certain NWPs require the permittee to submit a PCN, and thus
request confirmation from the district engineer prior to commencing the
proposed NWP activity, to ensure that the NWP activity complies with
the terms and conditions of the NWP. The requirement to submit a PCN is
identified in the NWP text, as well as certain general conditions.
General condition 18 requires non-federal permittees to submit PCNs for
any proposed activity that might affect ESA-listed species or
designated critical habitat, if listed species or designated critical
habitat are in the vicinity of the proposed activity, or if the
proposed activity is located in critical habitat. General condition 20
requires non-federal permittees to submit PCNs for any proposed
activity that may have the potential to cause effects to any historic
properties listed in, determined to be eligible for listing in, or
potentially eligible for listing in, the National Register of Historic
Places.
In the PCN, the project proponent must specify which NWP or NWPs he
or she wants to use to provide the required Department of Army (DA)
authorization under Section 404 of the Clean Water Act and/or Section
10 of the Rivers and Harbors Act of 1899. For voluntary NWP
verification requests (where a PCN is not required), the request should
also identify the NWP(s) the project proponent wants to use. The
district engineer should verify the activity under the NWP(s) requested
by the project proponent, as long as the proposed activity complies
with all applicable terms and conditions, including any applicable
regional conditions imposed by the division engineer. All NWPs have the
same general requirements: That the authorized activities may only
cause no
[[Page 2748]]
more than minimal individual and cumulative adverse environmental
effects. Therefore, if the proposed activity complies with the terms
and all applicable conditions of the NWP the applicant wants to use,
then the district engineer should issue the NWP verification unless he
or she exercises discretionary authority and requires an individual
permit. If the proposed activity does not meet the terms and conditions
of the NWP identified by the applicant in his or her PCN, and that
activity meets the terms and conditions of another NWP identified by
the district engineer, the district engineer will process the PCN under
the NWP identified by the district engineer. If the district engineer
exercises discretionary authority, he or she should explain to the
applicant why the proposed activity is not authorized by an NWP.
Pre-construction notification requirements may be added to NWPs by
division engineers through regional conditions to require PCNs for
additional activities. For an activity where a PCN is not required, a
project proponent may submit a PCN voluntarily, if he or she wants
written confirmation that the activity is authorized by an NWP. Some
project proponents submit permit applications without specifying the
type of authorization they are seeking. In such cases, the district
engineer will review those applications and determine if the proposed
activity qualifies for NWP authorization or another form of DA
authorization, such as a regional general permit (see 33 CFR 330.1(f)).
In response to a PCN or a voluntary NWP verification request, the
district engineer reviews the information submitted by the prospective
permittee. If the district engineer determines that the activity
complies with the terms and conditions of the NWP, he or she will
notify the permittee. Activity-specific conditions, such as
compensatory mitigation requirements, may be added to an NWP
authorization to ensure that the activity to be authorized under the
NWP will result in no more than minimal individual and cumulative
adverse environmental effects. The activity-specific conditions are
incorporated into the NWP verification, along with the NWP text and the
NWP general conditions. In general, NWP verification letters will
expire on the date the NWP expires (see 33 CFR 330.6(a)(3)(ii)),
although district engineers have the authority to issue NWP
verification letters that will expire before the NWP expires, if it is
in the public interest to do so.
If the district engineer reviews the PCN or voluntary NWP
verification request and determines that the proposed activity does not
comply with the terms and conditions of an NWP, he or she will notify
the project proponent and provide instructions for applying for
authorization under a regional general permit or an individual permit.
District engineers will respond to NWP verification requests, submitted
voluntarily or as required through PCNs, within 45 days of receiving a
complete PCN. Except for NWP 49, and for proposed NWP activities that
require Endangered Species Act section 7 consultation and/or National
Historic Preservation Act section 106 consultation, if the project
proponent has not received a reply from the Corps within 45 days, he or
she may assume that the project is authorized, consistent with the
information provided in the PCN. For NWP 49, and for proposed NWP
activities that require ESA Section 7 consultation and/or NHPA Section
106 consultation, the project proponent may not begin work before
receiving a written NWP verification. If the project proponent
requested a waiver of a limit in an NWP, the waiver is not granted
unless the district engineer makes a written determination that the
proposed activity will result in no more than minimal individual and
cumulative adverse environmental effects, and issues an NWP
verification.
F. Executive Order 13783, Promoting Energy Independence and Economic
Growth
Section 2(a) of E.O. 13783 requires federal agencies to review
their existing regulations that potentially burden the development or
use of domestically produced energy resources, with particular
attention to oil, natural gas, coal, and nuclear resources. For the
Corps, the NWPs authorize activities associated with the development or
use of domestically produced energy resources. In response to E.O.
13783, Office of the Assistant Secretary of the Army (Civil Works)
issued a report that reviewed 12 NWPs that authorize activities
associated with the development or use of domestically produced energy
resources. That report included recommendations for changes that could
be made to nine NWPs to support the objectives of E.O. 13783.
The Office of the Assistant Secretary of the Army (Civil Works)
issued its report on October 25, 2017, and the November 28, 2017, issue
of the Federal Register (82 FR 56192) published a notice of
availability for that report. Section 2(g) of E.O. 13783 states that
agencies should, as soon as practicable and as appropriate and
consistent with law, publish for notice and comment proposed rules that
would implement the recommendations in their reports. Section 2(g)
further states that agencies shall endeavor to coordinate the
regulatory reforms identified in their reports with their activities
undertaken in compliance with E.O. 13771, ``Reducing Regulation and
Controlling Regulatory Costs.''
G. Executive Order 13777, Enforcing the Regulatory Reform Agenda
On February 24, 2017, the President signed E.O. 13777, ``Enforcing
the Regulatory Reform Agenda,'' which required agencies to evaluate
existing regulations and make recommendations to the agency head
regarding their repeal, replacement, or modification, consistent with
applicable law. The E.O. specified that agencies must attempt to
identify regulations that eliminate jobs or inhibit job creation; are
outdated, unnecessary, or ineffective; impose costs that exceed
benefits; create a serious inconsistency or otherwise interfere with
regulatory reform initiatives and policies; or meet other criteria
identified in that Executive Order. Pursuant to this E.O., in the July
20, 2017, issue of the Federal Register (82 FR 33470) the Corps
published a notice seeking public input from state, local, and tribal
governments, small businesses, consumers, non-governmental
organizations, and trade associations on its existing regulations that
may be appropriate for repeal, replacement, or modification. Some of
the changes to the NWPs in this proposal are intended to address some
of the comments received in response to the July 20, 2017, Federal
Register notice. Comments received in response to the July 20, 2017,
Federal Register notice can be viewed at www.regulations.gov in docket
number COE-2017-0004.
H. Executive Order 13921, Promoting American Seafood Competitiveness
and Economic Growth
On May 7, 2020, the President signed Executive Order 13921 on
Promoting American Seafood Competitiveness and Economic Growth. Section
6(b) of the E.O., ``Removing Barriers to Aquaculture Permitting,''
requires the Secretary of the Army, acting through the Assistant
Secretary of the Army for Civil Works, to ``develop and propose for
public comment, as appropriate and consistent with applicable law,''
NWPs authorizing finfish aquaculture activities and seaweed aquaculture
activities in marine and coastal waters, including ocean waters beyond
the territorial sea within the exclusive economic zone of the United
States.
[[Page 2749]]
Section 6(b) of the E.O. also requires the Secretary of the Army,
acting through the Assistant Secretary of the Army for Civil Works, to
``develop and propose for public comment, as appropriate and consistent
with applicable law,'' a proposed NWP authorizing multi-species
aquaculture activities in marine and coastal waters, including ocean
waters beyond the territorial sea within the exclusive economic zone of
the United States. Section 6(b) of the E.O. also requires the Secretary
of the Army, acting through the Assistant Secretary of the Army for
Civil Works to ``assess whether to develop'' NWPs for finfish
aquaculture activities and seaweed aquaculture activities in other
waters of the United States. Section 6(b) also requires the Secretary
of the Army, acting through the Assistant Secretary of the Army for
Civil Works, to assess whether to develop a United States Army Corps of
Engineers NWP authorizing multi-species aquaculture activities in other
waters of the United States.
Instead of proposing a new, separate NWP for authorizing structures
in coastal waters and federal waters on the outer continental shelf for
multi-species aquaculture activities, the Corps proposed to include
provisions allowing additional species to be cultivated with seaweed
mariculture activities authorized under proposed new NWP A and finfish
mariculture activities authorized under proposed new NWP B. In
addition, the Corps invited public comment on whether a separate NWP
should be issued to authorize structures or work regulated by the Corps
for multi-species mariculture activities.
As required by the Executive Order, the Corps proposed to issue two
new NWPs: NWP A to authorize seaweed mariculture activities in
navigable waters of the United States, including federal waters on the
outer continental shelf, and NWP B to authorize finfish mariculture
activities in these waters. Based on the reasons set out in the final
rule, the Corps has decided to issue these two permits. These new NWPs
authorize structures and work in navigable waters of the United States
under Section 10 of the Rivers and Harbors Act of 1899. These new NWPs
also authorize seaweed and finfish mariculture structures attached to
the seabed on the outer continental shelf. Section 4(f) of the Outer
Continental Shelf Lands Act of 1953 as amended (43 U.S.C. 1333(e)),
extended the Corps' Rivers and Harbors Act of 1899 section 10
permitting authority to artificial islands, installations, and other
devices located on the seabed, to the seaward limit of the outer
continental shelf (see 33 CFR 320.2(b)). On the outer continental
shelf, the seaweed and finfish mariculture structures may be anchored
to the seabed, and thus require section 10 authorization as devices
located on the seabed. Each of these NWPs includes a provision on
multi-trophic species mariculture activities in marine and coastal
waters, including federal waters on the outer continental shelf. This
provision for multi-trophic species mariculture gives flexibility to
these NWPs to allow mariculture operators to propagate additional
species, such as mussels, on their seaweed or finfish mariculture
structures. Including this provision was an alternative to developing a
separate NWP for multi-trophic species mariculture activities, and
provides NWP authorization that is responsive to the E.O. The Corps
recognizes that some mariculture operators may choose to produce
seaweeds or finfish exclusively. As discussed in this final rule, the
Corps issued proposed new NWP A as NWP 55 and issued proposed new NWP B
as NWP 56.
I. 2018 Legislative Outline for Rebuilding Infrastructure in America
On February 12, 2018, the Administration issued its ``Legislative
Outline for Rebuilding Infrastructure in America.'' In Part 3
(Infrastructure Permitting Improvement), Principle I.C.1 recommends
reforms for eliminating redundancy, duplication, and inconsistency in
the application of clean water provisions. One of the recommended
reforms was to make statutory changes to authorize Federal agencies to
select and use NWPs without additional review by the Corps. Principle
I.C.1 recommends allowing Federal agencies to move forward on NWP
projects without submitting PCNs to the Corps. That principle also
states that removing PCN requirements for Federal agencies would allow
the Corps to focus on projects that do not qualify for NWPs, such as
activities that require individual permits that have greater
environmental impacts.
Consistent with the recommendation included in the Legislative
Outline, in the 2020 Proposal the Corps invited comment on whether it
can use its existing authority to create specific procedures or
conditions by which Federal agencies that want to use NWPs for
regulated activities would not need to submit PCNs, consistent with
applicable law. The Corps specified that, under such a mechanism, the
Corps would retain under its authority for district engineers to
modify, suspend, or revoke NWP authorizations (see 33 CFR 330.5(d)),
and the right to take action to address situations where the Federal
agency incorrectly determined that the NWP terms and conditions were
met.
The Corps sought public comment on whether to exempt federal
agencies from PCN requirements under the theory that federal agencies
may employ staff who are environmental experts and who already review
these projects before submitting PCNs to the Corps to determine whether
they meet the criteria for the applicable NWP. These environmental
staff are responsible for ensuring that the agencies' proposed
activities comply with applicable federal laws, regulations, and
policies, as well as relevant Executive Orders. In the proposed rule
the Corps stated that it understands that non-federal permittees that
want to use the NWPs often hire consultants to help them secure NWP
authorization in compliance with applicable federal laws, regulations,
and policies and that these consultants may have similar expertise to
staff at federal agencies. These consultants may provide general
services to assist in securing NWP authorizations on behalf of their
clients, or they may specialize in complying with specific laws and
regulations, such as Section 7 of the Endangered Species Act, Section
106 of the National Historic Preservation Act, and the Essential Fish
Habitat provisions of the Magnuson-Stevens Act. Non-federal permittees
are not bound to comply with Executive Orders.
Consistent with this legislative principle, the Corps requested
comment on whether to modify the NWPs that require PCNs to limit the
PCN requirement to non-federal permittees. The Corps requested that
commenters provide their views on whether they support or oppose having
different PCN requirements for Federal and non-Federal permittees, with
supporting information to explain their views. After reviewing and
considering public comments on this proposal, the Corps has determined
not to finalize any change to PCN requirements for federal permittees.
II. Discussion of Public Comments
A. Overview
In response to the 2020 Proposal, the Corps received more than
22,700 comment letters, of which approximately 22,330 were form letters
pertaining to the proposed removal of the 300 linear foot limit for
losses of stream bed, the proposed changes to NWPs 21, 49, and 50, or
the proposed reissuance of NWP 12. In addition to the various form
letters, the Corps received
[[Page 2750]]
a few hundred individual comment letters. Those individual comment
letters, as well as examples of the various form letters, are posted in
the www.regulations.gov docket (COE-2020-0002) for this rulemaking
action. The Corps reviewed and fully considered all comments received
in response to the 2020 Proposal.
B. Responses to General Comments
Many commenters expressed general support for the proposed rule, as
well as the NWP program as a whole, and many commenters stated
opposition to the proposed changes to the NWPs or the use of NWPs to
authorize certain activities. Many commenters said that the NWP program
should be discontinued. Many commenters objected to reissuing the NWPs
ahead of schedule, stating that early reissuance of the NWPs presents
an unnecessary burden and cost to the agency and the public. Many
commenters stated that the proposed NWPs do not comply with the Clean
Water Act, the National Environmental Policy Act, the Endangered
Species Act, the National Historic Preservation Act, the Magnuson
Stevens Act, and other federal laws. Many commenters said that the NWP
program is pushing species closer to extinction.
The NWP program is an important component of the Corps Regulatory
Program because it provides an efficient means of authorizing
activities that result in no more than minimal individual and
cumulative adverse environmental effects so that the Corps can devote
more of its resources for evaluating proposed activities that require
Department of the Army (DA) authorization that have the potential to
cause more substantial adverse environmental effects. The
grandfathering provisions in the Corps' NWP regulations at 33 CFR
330.6(a)(3)(ii) and 330.6(b) and as described in Section I.D, Status of
Existing Permits, provide mechanisms to reduce regulatory burdens when
the Corps modifies or reissues the NWPs to replace existing NWPs. The
NWPs are issued in compliance with the Clean Water Act, the National
Environmental Policy Act, the Endangered Species Act, the National
Historic Preservation Act, the Magnuson Stevens Act, and other
applicable federal laws.
Several commenters said that the proposal is not compliant with the
regulations that govern NWPs. Several commenters stated that every NWP
authorization should be announced through a public notice. Several
commenters said that the Corps does not have the authority to enforce
state conditions. One commenter stated that each NWP should include a
state-level review prior to verification. One commenter asserted that
the proposal violates the authority of individual states to resolve
noncompliance with water quality standard permits. One commenter stated
that the Corps should ensure compliance with Safe Water Drinking Act
when verifying NWP eligibility. One commenter said that the proposed
rule conflicts with efforts to update state general permits.
The 16 NWPs issued in this final rule comply with the Corps' NWP
regulations at 33 CFR part 330. The NWPs authorize only those
activities that have no more than minimal individual and cumulative
adverse environmental effects, so it is not necessary to issue public
notices to announce the tens of thousands of NWP verification letters
Corps districts issue each year. The Corps acknowledges that it does
not have the authority to enforce conditions provided by states, except
for those conditions added to the NWPs by water quality certifications
by certifying authorities and Coastal Zone Management Act consistency
concurrences issued by states, that are within the Corps' legal
authority to enforce. States can take actions to enforce their own
water quality requirements, including permits issued under Section 402
of the Clean Water Act. The Corps does not have the legal authority to
enforce the Safe Water Drinking Act. The issuance or reissuance of the
NWPs is independent of the issuance of general permits by states, or
the issuance of state programmatic general permits by Corps districts.
Several commenters said that the proposed rule did not allow
sufficient time for adequate review by states and tribes. Several
commenters requested additional time to review the proposed NWPs. One
commenter said that the comment period should be extended by 180 days.
One commenter stated that Corps divisions and districts should not
solicit comments on proposed regional conditions concurrently with the
public comment period of the NWP reissuance. Many commenters said that
the Corps should have a lead district for every state.
For the 2020 Proposal, the Corps provided a 60-day comment period,
which is same duration the Corps has used for past rulemaking actions
involving the issuance, reissuance, and/or modification of the NWPs.
The Corps sent response letters to entities that made timely requests
for extensions of the comment period for the 2020 Proposal. In the 2020
Proposal, the Corps did not propose a large number or substantial
changes to the NWPs. Soliciting public comment on proposed regional
conditions concurrently with the proposed issuance or reissuance of the
NWPs is consistent with the Corps' NWP regulations at 33 CFR
330.5(b)(2)(ii). The Corps has a designated a lead district for each
state; these districts have been identified since 2004. As discussed in
Section I.A., the Corps issued a Director's Policy Memorandum on May
15, 2018, that further clarified its policy for designating a lead
district for activities that require Department of the Army permits
that cross district or state boundaries.
One commenter stated that the Corps is required under Section
404(e) of the Clean Water Act to hold a public hearing, which it cannot
meaningfully accomplish given the pandemic. One commenter said the NWPs
should not allow losses of up to \1/2\-acre of waters of the United
States in areas that have already been heavily impacted and should not
be used in areas where critical and essential habitat exists for
species that are federally threatened or endangered species.
The Corps declined to hold a public hearing on the proposed NWPs
because it determined that a public hearing was unlikely to provide
additional information that would inform the Corps' decision on whether
to issue these NWPs. Under the Corps' regulations at 33 CFR 327.4(b),
requests for public hearing under this paragraph shall be granted,
unless the Corps determines that the issues raised are insubstantial or
there is otherwise no valid interest to be served by holding a public
hearing. The Corps received approximately 22,700 comments on the
proposed rule, and it is unlikely that any statements provided during a
public hearing would raise issues that are different that the issues or
concerns discussed in the written comments received in response to the
2020 Proposal.
The NWPs can be used in any area of the United States, except where
the NWPs have been revoked by division engineers on a regional basis
(e.g., to use a programmatic general permit instead of the NWPs) or
suspended or revoked by district engineers on a case-by-case basis. The
NWPs can be used in a variety of areas ranging from environmental
settings that have been heavily impacted by human activities to
environmental settings that have been shaped by fewer or less severe
impacts caused by human activities. For those NWPs with a \1/2\-acre
limit for losses of waters of the United States (e.g., NWPs
[[Page 2751]]
21, 29, 39, 40, 42, 43, 44, 50, 51, and 52), PCNs are required for all
proposed activities (except for maintenance activities under NWP 43 and
losses of less than \1/10\-acre of waters of the United States for NWP
51), which gives district engineers the opportunity to review proposed
activities in their current environmental setting and determine whether
those activities will result in no more than minimal individual and
cumulative adverse environmental effects.
The ability for division and district engineers to modify, suspend,
or revoke NWPs on a regional or case-by-case basis is a key tool for
ensuring that the NWPs only authorize activities that cause no more
than minimal individual and cumulative adverse environmental effects.
There is substantial variation in aquatic resource types across the
country, as well as a large amount of variability among geographic
regions in the quantity of those resources. Those regional differences
require division and district engineers to have the authority to tailor
the NWPs to address regional and site-specific concerns. The NWPs can
only be issued for a period of 5 years because of the statutory
language in section 404(e) of the Clean Water Act, as well as the
Corps' regulations at 33 CFR 330.6(b). Section 330.6(b) states that if
``an NWP is not modified or reissued within five years of its effective
date it automatically expires and becomes null and void.'' The 5-year
cycle for reissuing the NWPs provides sufficient time to make necessary
changes to the NWPs to ensure that the NWPs only authorize those
activities that result in no more than minimal individual and
cumulative adverse environmental effects.
Many commenters objected to the proposed NWPs, stating that they
authorize activities that result in more than minimal individual and
cumulative adverse environmental effects and that they do not authorize
categories of activities that are similar in nature. Many commenters
said that the Corps has not done any meaningful analysis of the
cumulative effects from NWPs. A few commenters said that since the
Corps does not require pre-construction notifications (PCNs) for all
NWP activities, it could not ensure that NWP activities result in no
more than minimal individual and cumulative adverse environmental
effects. One commenter said that Corps districts should improve their
tracking of cumulative impacts. A number of commenters opposed the
NWPs, stating that they authorize activities associated with larger
projects that have substantial environmental impacts. Several
commenters said that the NWPs should either not authorize activities
that impact streams and rivers occupied by anadromous salmon, or
compensatory mitigation should always be required for those activities.
One commenter stated that the NWPs should not be used in areas with
substantial cumulative impacts, such as essential fish habitat and
areas inhabited by ESA-listed species. Many commenters said that Corps
should fund an independent evaluation of its methodology for assessing
cumulative impacts. One commenter said that the proposal should be
based on peer-reviewed scientific analysis. One commenter stated that
the proposal should include a scientific support document. One
commenter said that NWPs should only authorize activities with
predictable environmental effects and outcomes.
The NWP activities that do not require PCNs are those activities
that have characteristics that do not result in more than minimal
adverse environmental effects, such as small structures in navigable
waters subject to section 10 of the Rivers and Harbors Act of 1899 or
minor fills in waters of the United States associated with maintenance
activities or temporary impacts.
For the issuance or reissuance of these NWPs, the Corps has
conducted the required cumulative effects analyses. In the national
decision document for each NWP issued or reissued in this final rule,
the Corps evaluated the cumulative impacts that are anticipated to
occur during the 5-year period the NWPs are expected to be in effect.
The cumulative impacts are evaluated against the current environmental
setting or baseline, in accordance with typical practices for
conducting environmental impact analyses. The Corps' public interest
review regulations at 33 CFR 320.4(a)(1) and the Corps' general permit
regulations at 33 CFR 322.2(f) and 323.2(h) require consideration of
cumulative effects for the issuance of permits.
For those NWPs that authorize discharges of dredged or fill
material into waters of the United States, the Corps complies with the
U.S. EPA's regulations at 40 CFR 230.7(b)(3) for assessing cumulative
impacts for the issuance of general permits. Section 230.7(b)(3)
requires the permitting authority (e.g., the Corps) to predict
cumulative effects by evaluating the number of individual discharge
activities likely to be regulated under a general permit until its
expiration, including repetitions of individual discharge activities at
a single location. In its cumulative effects analyses for the issuance
or reissuance of an NWP, the Corps goes further than estimating the
number of times an NWP may be used to authorize activities during the
5-year period it is expected to be in effect by estimating the acreage
of impacts and the acreage of compensatory mitigation required by
district engineers during that 5-year period. In its analysis of the
effects or impacts of the proposed issuance or reissuance of the NWPs
under the Council of Environmental Quality's current NEPA regulations
at 40 CFR 1508.1(g), the Corps also estimates the impacts that are
reasonably foreseeable and have a reasonably close causal relationship
to the proposed action during the 5-year period the NWP is expected to
be in effect.
These analyses of effects and their associated estimates of
authorized activities, authorized impacts to jurisdictional waters and
wetlands, and compensatory mitigation required by district engineers,
include NWP activities that require PCNs and NWP activities that do not
require PCNs. The Corps disagrees that an independent evaluation of
these approaches to cumulative effects is necessary, or that a peer-
reviewed scientific analysis or a scientific support document should be
prepared. The Corps follows existing federal regulations for assessing
cumulative effects. In its evaluations of individual and cumulative
adverse environmental effects of activities authorized by NWPs, the
Corps considers reasonably foreseeable effects or impacts, especially
those effects or impacts that are directly or indirectly caused by the
activity authorized under the Corps' permitting authorities under
Section 10 of the Rivers and Harbors Act of 1899 and Section 404 of the
Clean Water Act.
The NWP program provides a three-tiered approach to ensure
compliance with Section 404(e) of the Clean Water Act. Those three
tiers are: (1) the terms and conditions of the NWPs issued by Corps
Headquarters; (2) the authority of division engineers to modify,
suspend, or revoke NWPs on a regional basis; and (3) the authority of
district engineers to modify, suspend, or revoke NWPs on a case-by-case
basis. Section 404(e) of the Clean Water Act does not specify how broad
or narrow a category of activity must be in order to be covered by a
general permit. Therefore, that section of the Clean Water Act gives
the Corps the discretion to identify categories of activities for the
issuance of NWPs. The Corps interprets broadly the requirement for
general permits to authorize categories of activities that are similar
in nature, to provide program
[[Page 2752]]
efficiency, to keep the number of NWPs manageable, and to facilitate
implementation by the Corps and project proponents that need to obtain
Department of the Army (DA) authorization for activities that have no
more than minimal adverse environmental effects.
While the Corps recognizes that many NWP activities may be
components of larger overall projects, the Corps' authorities under the
NWP program are limited to discharges of dredged or fill material into
waters of the United States that are regulated under Section 404 of the
Clean Water Act, and structures and work in navigable waters that are
regulated under Section 10 of the Rivers and Harbors Act of 1899. The
Corps does not regulate other components of those larger overall
projects, such as activities that occur in upland areas. In many cases,
the NWPs are authorizing minor features that may be part of those
larger overall projects but that still does not bring those larger
upland features into the Corps' jurisdiction.
Division engineers can impose regional conditions on the NWPs to
protect rivers and streams inhabited by anadromous fish, including
salmon. For those salmonids that are listed as endangered or threatened
under the Endangered Species Act (ESA), general condition 18 requires
PCNs for all NWP activities proposed to be undertaken by non-federal
permittees that might affect those listed species or their designated
critical habitat (or proposed species or proposed critical habitat), or
that occur in their designated or proposed critical habitat. If a
proposed NWP activity may adversely affect essential fish habitat, the
district engineer will conduct essential fish habitat consultation with
the NMFS. District engineers have the discretion to require
compensatory mitigation to offset stream losses caused by NWP
activities. After conducting ESA section 7 consultation or essential
fish habitat consultation, the district engineer may determine that
stream compensatory mitigation is necessary to ensure that the NWP
activity results in no more than minimal individual and cumulative
adverse environmental effects. A division engineer has the authority to
modify, suspend, or revoke one or more NWPs in a geographic region if
he or she determines that the use of that NWP or NWPs will result in
more than minimal cumulative adverse environmental effects.
One commenter said the NWPs should not authorize activities that
result in adverse environmental impacts. One commenter stated that the
terms and conditions of the NWPs should not be changed to be less
protective of the environment. Several commenters said that public
notices should be issued for NWP PCNs to disclose proposed NWP
activities and increase public participation. A number of commenters
suggested that NWPs should require no net loss of aquatic resources. A
number of commenters asked why the proposed NWPs use the term ``no more
than minimal adverse environmental effects'' instead of ``no more than
minimal adverse effects on the aquatic environment.''
Section 404(e) of the Clean Water Act recognizes that activities
authorized by general permits, including NWPs, will result in adverse
environmental impacts, but limits those adverse impacts so that they
can only be no more than minimal. The Corps has adopted terms and
conditions for the NWPs to be sufficiently protective of the aquatic
environment while allowing activities that result in no more than
minimal adverse environmental effects to be conducted.
Requiring public notices for PCNs would be contrary to the purpose
of the general permit program established through section 404(e) of the
Clean Water Act, for a streamlined authorization process for activities
that result in no more than minimal individual and cumulative adverse
environmental effects. In addition, it is unlikely that there would be
any meaningful public comment submitted to Corps districts in response
to public notices for the minor activities authorized by these NWPs
that would warrant the reduction in permitting efficiency providing
such a comment period would cause. Compensatory mitigation can only be
required by the district engineer after he or she reviews the PCN and
determines that compensatory mitigation is necessary to comply with the
``no more than minimal adverse environmental effects'' requirement for
NWPs (see 33 CFR 330.1(e)(3)). There is no federal statute or
regulation that requires ``no net loss'' of aquatic resources. The ``no
overall net loss'' goal for wetlands articulated in the 1990 U.S. EPA-
Army Memorandum of Agreement for mitigation for Clean Water Act section
404 permits states that the section 404 permit program will contribute
to that national goal. The 1990 Memorandum of Agreement only applies to
standard individual permits, not to general permits.
The NWP program provides valuable protection to the Nation's
aquatic resources by establishing incentives to avoid and minimize
losses of jurisdictional waters and wetlands in order to qualify for
the streamlined NWP authorizations. A large majority of fills in
jurisdictional waters and wetlands authorized by general permits and
individual permits are less than \1/10\-acre (see Figure 5.1 in the
Regulatory Impact Analysis for this final rule, which is available in
the www.regulations.gov docket (COE-2020-0002)). The 16 NWPs use the
term ``no more than minimal adverse environmental effects'' to be
consistent with the text of Section 404(e) of the Clean Water Act and
33 CFR 322.2(f)(1) for Section 10 of the Rivers and Harbors Act of
1899. When making no more than minimal adverse environmental effects
determinations for proposed NWP activities, the district engineer
considers the adverse effects to the aquatic environment and any other
factor of the public interest (e.g., 33 CFR 330.1(d)). The district
engineer also applies the 10 criteria listed in paragraph 2 of Section
D, District Engineer's Decision. The use of the term ``no more than
minimal adverse environmental effects'' does not expand the Corps'
scope of analysis. The Corps' control and responsibility remains
limited to the activities it has the authority to regulate, and the
effects to the environment caused by those activities.
Several commenters said that the proposed NWPs are not sufficiently
protective of freshwater mussels. One commenter stated that the NWPs
should be modified to provide additional protections to wilderness
areas. Several commenters identified specific areas of the country
where they were concerned that the use of the NWPs would authorize
activities with adverse environmental impacts. Many commenters said
that the NWPs have increased coastal communities' vulnerability to
future flood events by accelerating wetland alteration following
hurricanes. One commenter stated that the NWPs should be revoked in
areas included under the Safe Drinking Water Act, such as public water
systems source water areas. One commenter said that all NWPs should be
subject to an acreage limit of \1/10\-acre.
Impacts to freshwater mussels that are listed as endangered or
threatened under the ESA are addressed through general condition 18 and
the subsequent ESA section 7 consultations that occur when district
engineers review PCNs and determine that a proposed NWP activity may
affect listed mussels. Where there are concerns about the use of NWPs
in wilderness areas and other specific waterbodies or geographic areas
of the United States, division engineers can add regional conditions to
the NWPs to restrict or prohibit their use in those areas. The Corps
does not have the legal authority to address the
[[Page 2753]]
vulnerability of coastal communities to future flood events or the loss
of wetlands in coastal areas due to erosion, subsidence, and sea level
rise. Public water systems source water areas are generally watersheds,
and the Corps does not have the authority to regulate activities in
uplands in these watersheds that may affect water supplies for
communities. For those NWP activities that require PCNs, district
engineers can consider effects to water supplies caused by regulated
activities, as one of the Corps' public interest review factors (i.e.,
water supply and conservation at 33 CFR 320.4(m)) that can be a basis
for exercising discretionary authority. The Corps believes that the \1/
2\-acre limit for the NWPs, the PCN review process, and the ability of
division engineers to modify, suspend, or revoke the NWPs on a regional
or case-specific basis is sufficient for ensuring that the NWPs that
have the \1/2\-acre limit authorize only those activities that result
in no more than minimal individual and cumulative adverse environmental
effects.
One commenter stated that implementing NWPs under the Navigable
Waters Protection Rule (NWPR) will result in more than minimal impacts
and not account for areas that were jurisdictional but are not under
current rule. Many commenters said that the NWPs should include
language clarifying that not all ditches constructed in adjacent
wetlands are jurisdictional. Many commenters stated that the discussion
of wetland jurisdiction in the NWPs should mirror that in the NWPR.
Many commenters asserted that there are inconsistencies between the
proposed NWPs and the NWPR. Several commenters said that the
terminology in the NWPs should be consistent with the NWPR, especially
the terms ``stream,'' ``tributary,'' and ``ephemeral.''
The NWPs are used to authorize activities in waters and wetlands
that are jurisdictional under the Corps' permitting authorities:
Section 404 of the Clean Water Act and Section 10 of the Rivers and
Harbors Act of 1899. If a project proponent wants to discharge dredged
or fill material into a waterbody that is not subject to Clean Water
Act jurisdiction under the NWPR, then DA authorization under an NWP or
any other type of Corps permit is not required for that proposed
discharge. The Corps declines to add language to this final rule
regarding the jurisdictional status of ditches under the Clean Water
Act because that jurisdictional status is more appropriately addressed
through application of the provisions of the NWPR at 33 CFR part 328.
Many of the NWPs can be used to authorize discharges of dredged or fill
material into numerous wetland types that are subject to Clean Water
Act jurisdiction under the NWPR. There are no inconsistencies between
the proposed NWPs and the NWPR. The NWPs can be used to authorize
specific activities in waters and wetlands that are subject to Clean
Water Act jurisdiction under the NWPR. Some of the NWPs specifically
authorize discharges of dredged or fill material into streams, so the
Corps declines to replace the term ``stream'' with ``tributary.'' Under
the NWPR, ephemeral features, including ephemeral streams are excluded
from Clean Water Act jurisdiction.
One commenter requested that the Corps issue a new NWP with no PCN
requirements that authorizes emergency projects such as repair of
significant leaks from canals, tunnels, and other features, culvert
repair and replacement, critical pump plant repairs, and small scale
urgent natural disaster mitigation projects. One commenter suggested
that the Corps issue a new NWP to authorize natural disaster mitigation
projects (e.g., fire or flood repairs or mitigation projects) with an
acreage limit of \1/10\-acre. One commenter stated that the Corps
should issue a new NWP to authorize aggregate mining activities,
instead of NWP 44. One commenter said that the Corps should prioritize
NWP verifications for time-sensitive maintenance and emergency work.
One commenter stated that the proposal should include a list of
typically exempted activities, such as ditch maintenance. One commenter
said that that the NWPs should include a general condition to limit the
spread of invasive/noxious species.
The Corps declines to issue a new NWP to authorize the repair of
leaks from canals, tunnels, and other features because NWP 3 can be
used to authorize discharges of dredged or fill material into waters of
the United States or structures or work in navigable waters of the
United States to repair leaking structures or fills. The Corps also
declines to issue a new NWP to authorize natural disaster mitigation
projects. Some of these activities are already authorized by NWP 37,
emergency watershed protection and rehabilitation activities. Some of
these activities can also be authorized through the Corps' emergency
permitting procedures at 33 CFR 325.2(e)(4). Nationwide permit 44
authorizes aggregate mining activities, so it is not necessary to issue
another NWP to authorize those activities. District engineers currently
have the authority to prioritize authorization of time-sensitive
maintenance and emergency work, including the use of the emergency
permitting procedures at 33 CFR 325.2(e)(4). Certain NWPs include notes
that point to exemptions that may be related to authorized activities.
The Corps declines to add a general condition to the NWPs to require
permittees to take actions to limit the spread of invasive or noxious
species because such a condition would not be reasonably enforceable
and invasive or noxious species can spread through natural mechanisms
outside the control of permittees. The Corps' regulations at 33 CFR
325.4(a) requires permit conditions to be directly related to the
impacts of the proposal, appropriate to the scope and degree of those
impacts, and reasonably enforceable.
(1) Status of Existing Permits
In response to the 2020 Proposal, the Corps received comments
concerning the status of existing NWP authorizations and how the
issuance of the final rule may affect those existing authorizations.
The Corps also invited public comment on changing the expiration date
for the 2017 NWPs to avoid having two sets of NWPs in effect at the
same time.
Many commenters stated that current NWPs should expire on their
original expiration date (i.e., March 18, 2022). Several commenters
expressed support for the 2017 NWPs expiring the day before the new
NWPs become effective in order to provide certainty and continuity
without imposing burdens on permittees, provided that all activities
authorized by the 2017 NWPs remain approved regardless of whether those
activities meet the requirements of the new NWPs. These commenters also
wanted to avoid having differing sets of NWPs in effect at the same
time.
Many commenters stated that the Corps proposed grandfathering
procedure would cause uncertainty and disruption to those who are
relying on the expiration date of the 2017 NWPs and the 12-month
grandfathering period. A few commenters said that the grandfathering
process and applicability was unclear. One commenter stated that
previously verified activities should be allowed to continue under the
2017 NWPs unless the new NWPs are more restrictive. One commenter
stated that if the NWPs issued in the final rule replaces the 2017 NWPs
and the NWPs issued in the final rule go into effect before the 2017
NWPs were originally scheduled to expire on March 18, 2022, the Corps
should notify all permittees who submitted PCNs or received NWP
[[Page 2754]]
verification letters under the 2017 NWPs.
The Corps acknowledges that that these changes to the NWPs may
cause uncertainty and disruption for some project proponents who have
received NWP verifications from the Corps. However, the Corps believes
this disruption will be limited because the activities affected by the
changes to the 12 existing NWPs are likely to continue to qualify for
NWP authorization. Further, project proponents can work with Corps
districts to efficiently obtain NWP verifications under the reissued
NWPs. The information previously submitted to Corps districts via PCNs
can be used to provide NWP verifications for many of the activities
that will be authorized by the new NWPs for different types of utility
line activities that were previously authorized by NWP 12. It is
impractical to require the Corps districts to reach out to all
permittees who received NWP verifications under the 2017 NWPs that are
reissued in this final rule because of the number of verified
activities. Once an NWP verification has been provided there is no
obligation for a permittee to undertake the work that has been
permitted; therefore, there it is impractical for the Corps to follow-
up on every verification to ascertain if the work has been completed
and/or whether the project proponent still intends to proceed with the
activity authorized under the NWP.
One commenter asked what would happen to activities approved under
the 2017 NWPs that would start construction prior to March 18, 2022,
but after the implementation dated of the new NWPs. One commenter
stated that activities that no longer qualify under the new NWPs but
were verified under the 2017 NWPs should have 18 months to complete the
authorized activity. One commenter questioned whether projects verified
under the 2017 NWPs would still be valid as verified or would they be
in non-compliance and require re-authorization either by NWP or by
individual permit.
If a project proponent received an NWP verification under one of
the 2017 NWPs, and the activity continues to be authorized by one of
the existing NWPs that was reissued, that activity continues to be
authorized by the 2017 NWP until it expires on March 18, 2022, unless
the district engineer specified a different expiration date in the NWP
verification letter (see 33 CFR 330.6(a)(3)(ii)). In contrast to the
grandfathering provision at 33 CFR 330.6(b), the grandfathering
provided by section 330.6(a)(3)(ii) is not dependent on when the
project proponent commences construction. If the activity is not
authorized by the reissued NWP, then the project proponent has 12
months to complete the authorized activity after the 16 final NWPs go
into effect as long as the project proponent has commenced construction
or is under contract to commence construction before the new expiration
date for the twelve 2017 NWPs that are reissued in this final rule (see
33 CFR 330.6(b)). The Corps' regulations at 33 CFR 330.6(b) specify a
12-month grandfathering period for activities that no longer qualify
for authorization under the reissued NWP if the activity has commenced
or is under contract to commence prior to the expiration of the NWP. To
change that 12-month period to 18 months would require rulemaking to
amend the regulation. The validity of the prior NWP authorization would
depend on whether the activity continues to be authorized by any of the
16 NWPs issued in this final rule, and whether any of the
grandfathering provisions in 33 CFR 330.6 apply.
One commenter said that based on section 330.6(b) permittees should
have until March 18, 2023 to complete projects authorized under the
2017 NWPs as long as they are under construction or contract to
commence construction. One commenter stated that special emphasis
should be placed on NWP 12 if it is split into three NWPs, to ensure
that activities previously authorized under the 2017 NWP 12 continue to
be permitted through the date specified in the verification letter. One
commenter stated that the Corps should allow for a reasonable
transition between existing activities authorized by an NWP and the new
NWPs, for up to one year.
As discussed above, electric utility line and telecommunications
activities and utility line activities for water and other substances
continue to be authorized by the 2017 NWP 12 for up to 12 months as
long as the project proponent has commenced construction or is under
contract to commence construction before NWPs 57 and 58 go into effect.
Given the anticipated effective date of this final rule, the 12-month
grandfathering provision is likely to end close to March 18, 2022. The
Corps believes that the current regulations provide a reasonable
transition from the 2017 NWPs to the 16 NWPs issued in this final rule.
(2) Pre-Construction Notification Requirements
A few commenters stated they are supportive of the reduction of the
number of PCN thresholds under various NWPs. A few commenters said they
are supportive of the removal of the 300 linear foot PCN threshold.
Many commenters stated that they are opposed to reducing the number of
PCN thresholds for the NWPs because they believe these PCN thresholds
are necessary to ensure that the activities authorized by these NWPs
have no more than minimal adverse environmental effects. A few
commenters said that the lack of PCNs does not meet the national no-
net-loss of aquatic resources goal because these losses are not being
mitigated. A few commenters stated their opposition to the removal of
the 300 linear foot PCN thresholds. Several commenters said that they
are opposed to federal agencies not having to submit PCNs because it is
contrary to the Clean Water Act.
The changes to the PCN thresholds for the NWPs are discussed in the
sections of the final rule that apply to each NWP. With the removal of
the 300 linear foot limit for losses of stream bed, the Corps has also
removed the ability of district engineers to waive that 300 linear foot
limit on a case-by-case basis after reviewing PCNs. Activities can be
authorized by NWPs with no compensatory mitigation requirements as long
as those activities result in no more than minimal individual and
cumulative adverse environmental effects. In FY 2018, approximately 11
percent of activities verified by district engineers as qualifying for
NWP authorization required compensatory mitigation. There is no
requirement in law or regulation for no net loss of aquatic resources.
The requirement for what can be authorized by an NWP is that
established by Section 404(e) of the Clean Water Act requiring
activities authorized by NWPs to cause only minimal individual and
cumulative adverse environmental effects. As discussed in Section II.D,
the Corps is retaining PCN requirements for federal agencies that use
the NWPs to authorize their activities.
A few commenters said that PCNs should be required for all NWP
activities to ensure the authorized activities are not affecting the
environment adversely and to ensure the permittee is avoiding and
minimizing impacts to the maximum extent practicable. One commenter
stated that a PCN should be required to ensure compliance with Section
106 of the National Historic Preservation Act. One commenter said that
the timing of the review process for a PCN is not identified in the
proposed rule for any of the NWPs.
The Corps establishes PCN thresholds for those NWP activities that
have the potential to cause more than minimal
[[Page 2755]]
adverse environmental effects, to provide activity-specific review and
allow district engineers to exercise discretionary authority and
require individual permits for activities that will have more than
minimal adverse environmental effects. General condition 20 establishes
PCN requirements for proposed NWP activities that have the potential to
cause effects to historic properties that are undertaken by non-federal
permittees. The timing of the PCN review process is provided in general
condition 32.
One commenter stated that the Corps undertakes many actions under
its permitting authorities for which the tribes and villages are not
notified. One commenter asked how the Corps ensures no more than
minimal adverse environmental effects if a default NWP authorization
occurs after 45 days has passed after the district engineer receives a
PCN. One commenter asked for clarification as to how the Corps ensures
compliance for activities that do not require PCNs. One commenter
requested that Corps Headquarters clarify to each of the Corps
districts that it is up to the permittee to determine whether a PCN is
required or not.
In conjunction with the rulemaking process for the issuance of
these NWPs, Corps districts have been conducting consultation and
coordination with tribes to identify regional conditions and
coordination procedures to ensure compliance with general condition 17,
concerning tribal rights. Activities that qualify for the default
authorization that occurs 45-days after the district engineer receives
a complete PCN must comply with all conditions of the NWP, including
the general conditions and any applicable regional conditions imposed
by the division engineer. The permittee is responsible for reading the
NWPs and all of their conditions to determine whether he or she is
required to submit a PCN before proceeding with an authorized activity.
One commenter said that for linear projects that are considered
``single and complete,'' where some crossings do not require PCNs, the
permittee should not have to divulge the non-PCN crossing information
to the Corps because the permittee is not required to provide the same
level of documentation for non-PCN crossings, and the project proponent
should be free to move forward with the non-PCN crossings. One
commenter encouraged the Corps to implement a nationwide tracking and
monitoring system for NWPs with PCN requirements to share information
with cooperating resource agencies so that informed decisions can be
made regarding changes to the NWP program.
The information on the non-PCN crossings associated with a linear
project is necessary so that the district engineer can consider all
crossings of waters of the United States that require DA authorization
when making his or her determination that the proposed NWP activities
will result in no more than minimal cumulative adverse environmental
effects. The information required by paragraphs (b)(4)(i) and (ii) of
general condition 32 does not change these non-PCN crossings into those
requiring PCNs. The Corps tracks all NWP verifications issued for
activities that require PCNs and for activities reported to Corps
districts through voluntary PCNs where the permittee seeks written
verification even though he or she is not required to do so.
(3) Climate Change
Many commenters said that the Corps should consider climate change
during the reissuance of these NWPs. One commenter stated that the
Corps failed to analyze climate change, the risk of which will be
exacerbated by the issuance of the NWPs. Some of these commenters
stated that the Corps should consider increased energy consumption as a
foreseeable indirect effect of the Corps' decisions for these NWPs.
Several commenters asserted that the proposed changes to the NWPs will
have significant impacts on the environment, including climate change.
One commenter said that the cumulative impacts of stream and wetland
losses from NWP activities must be considered in the context of the
changing climate. Several commenters stated that the proposed NWPs help
support the nation's investment of its infrastructure, including
changes to infrastructure to address global climate change.
The Corps has considered climate change during the reissuance of
the NWPs, and each of the national decision documents includes a
discussion of climate change. Although some activities authorized by
various NWPs may be associated with energy production, distribution,
and use, the Corps does not have the authority to regulate or control
the production, distribution, or combustion of hydrocarbons and other
materials are sources of carbon dioxide and other greenhouse gases that
contribute to global climate change. Permittees may use equipment
during the construction of the NWP activity that emits carbon dioxide
and other greenhouse gases, but those emissions occur during the
construction period for the authorized activity and have an
insignificant contribution to cumulative greenhouse gas emissions in
the region. The activities authorized by NWPs may result in permanent
or temporary impacts to wetlands and streams, and the discharges of
dredged or fill material into waters of the United States and
structures and work in navigable waters of the United States are only a
subset of the variety of human activities that change the quantity and
quality of wetlands, streams, and other aquatic resources. Those other
human activities are discussed in section 4.0 of the national decision
documents for these NWPs. Some activities authorized by the NWPs, such
as utility line activities, bank stabilization activities, living
shorelines, and aquatic resource restoration activities contribute to
adaptation to climate change.
C. Comments on Proposed Actions Under Executive Order 13921, Promoting
American Seafood Competitiveness and Economic Growth
In response to the 2020 Proposal, the Corps received comments on
its proposed actions under Executive Order 13921, Promoting American
Seafood Competitiveness and Economic Growth. The comments on proposed
NWPs A and B for seaweed mariculture activities and finfish mariculture
activities, respectively, are discussed in Section II.G of this final
rule. In response to the section of the 2020 Proposal on E.O. 13921,
the Corps received a few comments on aquaculture in other waters of the
United States, but those commenters seemed to think that the
mariculture NWPs might also authorize aquaculture activities in those
other waters (e.g., freshwater lakes, ponds, and wetlands). The new
NWPs 55 (seaweed mariculture activities) and 56 (finfish mariculture
activities) limit those activities to estuarine and marine waters.
These new NWPs also authorize multi-trophic mariculture activities.
D. Comments on the 2018 Legislative Outline for Rebuilding
Infrastructure in America
In the 2020 Proposal, the Corps requested comment on whether to
modify the NWPs that require PCNs to limit the PCN requirement to non-
federal permittees. The Corps requested that commenters provide their
views on whether they support or oppose having different PCN
requirements for Federal and non-Federal permittees, with supporting
information to explain their views.
After considering the comments received in response to the proposal
based on the 2018 Legislative Outline
[[Page 2756]]
for Rebuilding Infrastructure in America, for the final NWPs the Corps
decided to continue to subject both federal permittees and non-federal
permittees to the same PCN requirements. Overall, the comments received
in response to this aspect of the proposed rule did not support a
reasoned and defensible rational for establishing different PCN
requirements for federal and non-federal entities that use the NWPs to
authorized activities that require DA authorization under Section 404
of the Clean Water Act and Section 10 of the Rivers and Harbors Act of
1899. The comments the Corps received did not provide a substantive
basis for establishing different PCN requirements for federal
permittees and non-federal permittees, or establishing that federal
permittees generally have a better record than non-federal permittees
for complying with the NWPs and complying with related laws such as the
Endangered Species Act and the National Historic Preservation Act.
While the Corps would retain its enforcement authorities under the
proposal, continuing to require federal agencies to submit PCNs is a
more efficient means of ensuring that the NWPs authorize only those
activities that result in no more than minimal individual and
cumulative adverse environmental effects.
Many commenters opposed the proposal to remove PCN requirements for
federal permittees that want to use the NWPs to authorize their
activities, because it would apply different PCN requirements and
standards to federal versus non-federal permittees. Some of these
commenters said this change may result in inadvertent violations. Some
of these commenters stated that applying different PCN requirements for
federal and non-federal permittees has no rational basis, and PCN
requirements should be based on the regulated activity, not who
undertakes the regulated activity.
After reviewing the comments received in response to this aspect of
the proposal, the Corps agrees that there is no substantive basis for
establishing different PCN requirements for federal and non-federal
permittees. The Corps is thus retaining the existing PCN requirements
for federal permittees.
Many commenters questioned whether federal agencies employ
environmental experts qualified to review the projects before
submitting the PCNs to the Corps and ensure that those federal agencies
comply with applicable laws, regulations, and policies. Some these
commenters said that expertise is inconsistent in terms of presence and
depth among different federal agencies. They stated that staff at Corps
districts are the best equipped with the technical knowledge and
familiarity to administer the program and provide compliance oversight.
The Corps agrees that knowledge regarding environmental laws and
regulations, and experience in preparing environmental documentation to
demonstrate compliance with environmental laws, varies among people as
a whole, and is not dependent on whether they work for a federal
government agency. As discussed in the 2020 Proposal, many non-federal
permittees seek the assistance of environmental consultants to help
them obtaining DA authorization through the NWP authorization process.
Many commenters pointed out that PCNs allow the NWP program to meet
the goal of no more than minimal individual and cumulative adverse
impacts to the environment. Many of them said that exempting activities
undertaken by federal agencies would reduce the ability of the Corps to
track the cumulative effects of the NWP program. Many commenters
expressed concerns with the Corps not assessing compensatory mitigation
for federal permittees. They said there would be no mechanism for
oversight and assurance that mitigation is completed and legally
binding. Some of these commenters stated that federal permittees would
have no incentive to avoid and minimize impacts and it is a clear
conflict of interest for federal agencies, as they are incentivized to
ensure their projects are permitted with as little cost as possible.
The Corps is continuing to require PCNs from federal permittees, so
there will be no change in the number of PCNs. District engineers will
still review PCNs and require compensatory mitigation and other forms
of mitigation when necessary to ensure that NWP activities result in no
more than minimal individual and cumulative adverse environmental
effects.
Regarding the proposed definition of non-federal permittee, several
commenters asked about the circumstances under which a non-federal
permittee would be considered a federal permittee, and whether federal
funding or some other federal nexus involving a local partner would be
a factor. Some commenters inquired whether a state or local agency who
has been delegated NEPA authority be considered a non-federal
permittee. Several commenters said that there would need to be a
clearer definition to help identify federal permittees who would no
longer have to submit PCNs for proposed NWP activities. Because the
Corps is retaining PCN requirements for federal agencies, it declines
to speculate on how it would have implemented the proposal.
Several commenters stated that delegation of the section 404
permitting program to another federal agency is not likely to be
legally permissible and might expose the Corps to litigation. Some of
these commenters said that case law suggests that such delegation of a
federal agency's statutory authority is not allowed, especially in the
absence of memorandum of agreement between agencies. Not requiring PCNs
from federal permittees for NWP activities is not be a delegation of
the section 404 permitting program. The Corps continues to implement
the NWP program and take actions necessary ensure that NWP activities
comply with the terms and conditions of those authorizations, including
potential actions identified in its enforcement regulations at 33 part
CFR 326.
Several commenters did not support the inclusion of state
departments of transportation (DOTs) that have been assigned NEPA
responsibilities in the category of federal permittees that would not
have to submit PCNs for proposed NWP activities. Some of these
commenters said that state DOTs may forgo internal mitigation programs
if PCNs were no longer required and district engineers would not have
the ability to impose mitigation requirements on NWP activities through
conditions added to the NWP authorization. Some commenters said that
long-term linear transportation projects are some of the biggest
contributors of turbidity in the nation's waterbodies and can have
permanent impacts to streams and wetlands. Some DOTs already have
funding agreements with the Corps in most states to provide
supplemental staff that are required to implement impartial decision-
making and are overseen and reviewed by non-funded regulators to ensure
transparency and fairness. A few commenters said that if these critical
safeguards be removed, DOTs will not be impartial or unbiased, and
could undermine the environmental protections provided by the PCN
process. Since the Corps is not changing the PCN requirements for
federal permittees, it declines to speculate on how it would have
implemented the proposed definition of ``non-federal permittee'' and
other aspects of the proposal.
A few commenters stated that removing PCN requirements for federal
permittees could limit the ability of states to ensure that state water
quality standards are being met under Section
[[Page 2757]]
401 of the Clean Water Act. If PCNs are not required, the regulatory
scope of water quality protection shifts from pre-impact permitting
review to more resource intensive field compliance, creating a burden
on the regulatory entities responsible for protection of water quality.
Pre-construction notifications ensure that NWP activities are
consistent with water quality standards, water quality management
plans/continuing planning process, total daily maximum loads, and anti-
degradation policy.
The PCN requirements do not affect the requirements of Section 401
of the Clean Water Act. If a certifying agency does not issue water
quality certification for the issuance of an NWP that does not require
pre-construction notification, the project proponent is still required
to obtain an activity-specific water quality certification or waiver
for the proposed discharge.
A few commenters stated that the further an agency's focus is from
natural resource management, the input from state fish and wildlife
agencies is more critical. These commenters said that the participation
of state natural resource agencies in the PCN review process helps
ensure potential impacts to state trust resources are considered, and
ensures public trust property is not taken without compensation. The
Corps does not coordinate PCNs with state natural resource agencies,
except for a few exceptions. Those exceptions are identified in
paragraph (d) of general condition 32.
Several commenters pointed out that both federal and state projects
are causes of some of the nation's largest wetland losses. These
commenters said that if PCN requirements are removed, there will be no
way to assess the impacts of these large-scale projects and it would
result in huge aquatic resource losses. Several commenters stated that
few federal agencies have the level of experience in working with and
consulting tribes and said that PCNs should continue to be required in
order to provide communication between the potentially impacted tribe,
the Corps, and the federal agency regarding any potential impacts to
tribal lands and resources. Since the Corps is retaining PCN
requirements for federal permittees, these concerns have been
addressed.
A commenter said that the preamble to the proposed rule explains
that the PCN process also provides a database to inform renewal of
NWPs. A couple of commenters stating that the Corps' assumption that
non-federal entities, such as private entities, non-profits and even
state governments do not possess the same or higher expertise than the
federal government is arbitrary and unfair. One commenter stated that
there has been an erosion of positions within agencies along with the
required expertise for such environmental reviews. Since the Corps is
retaining PCN requirements for federal permittees, there is no need to
speculate on how it would have implemented the proposal.
A couple of commenters said that Section 313 of the Clean Water Act
states in no uncertain terms that all federal agencies ``shall be
subject to, and comply with, all federal, state, interstate, and local
requirements respecting the control and abatement of water pollution in
the same manner, and to the same extent, as any nongovernmental
entity.'' A couple of commenters stated that removal of the PCN
requirements for federal permittees would make it difficult for states
to identify violations and impossible for the Corps to ensure that the
conditions of the permits are being property implemented, especially
since recent changes to the EPA's regulations for Clean Water Act
Section 401 water quality certifications, which preclude certifying
authorities from monitoring and enforcing conditions of permitted
activities. Since the Corps is retaining PCN requirements for federal
permittees, there is no need to respond to these comments.
One commenter requested clarification regarding use of the phrase
``NEPA responsibility for all federal highway project in the state'',
and asked whether the Corps intended to only provide federal permittee
status to those NEPA assignment states who accept all federal highway
projects in the state. One commenter stated that state transportation
agencies would gain efficiency by elimination of PCNs for many small
projects. A few commenters supported the proposal and believe it will
streamline review and approval of permitting while allowing the Corps
to focus on individual permitting needs. Several commenters supported
the proposed definition of ``non-federal permittee'' including the
inclusion of state DOTs. The Corps is not adopting the proposed
definition of ``non-federal permittee'' so it is not necessary to
address the comments on the proposed definition.
One commenter supports the PCN process and encourages the Corps to
work with state agencies for additional options such as reducing
comment periods to reduce overall time constraints associated with
Corps permitting. Several commenters suggested that there should be a
certification process through which individuals receive training by the
Corps and demonstrate that they have sufficient knowledge to preserve
the intent of the NWPs. They said the Corps should develop a set of
criteria that each entity needs to meet to demonstrate proficiency to
allow the entity to be exempt from submitting PCNs for proposed NWP
activities.
The Corps does not solicit comments from state agencies on proposed
NWP activities, except for certain NWP activities identified in
paragraph (d) of general condition 32. The Corps does support the
development of a certification process for potential users of the NWPs.
Certain NWPs do not require the submission of PCNs but for those that
do, district engineers will continue to review and render decisions on
those actions.
One commenter suggested that the Corps exempt private companies
that are undertaking projects in conjunction with, or in response to,
federal projects. One commenter stated that the Corps should clarify
whether states, or entities acting with or on behalf of states, would
be exempt from the requirement to submit PCNs when operating under the
Surface Transportation Block Grant Program, which allows states to
implement road projects and other projects using federal money with
some amount of regulatory oversight by the Federal Highways
Administration. A couple commenters suggested that if the Corps does
not require PCNs for activities undertaken federal permittees, the PCN
requirements for all applicants could be included as regional
conditions to the NWPs. The Corps is retaining the PCN requirements for
federal permittees, therefore it declines to speculate on how it would
have implemented the proposal.
One commenter suggested modifying the PCN exemption to only
encompass federal, state, or local agencies that have established their
credentials for application of the NWP program. One commenter suggested
an exemption from PCN requirements for federal permittees when pre-
construction notification is required solely as a result of federal
consultation thresholds noted in the NWP general conditions. One
commenter suggested there would be a benefit in including a statement
clarifying that state transportation agencies with NEPA delegation are
the federal leads in terms of ESA Section 7 and NHPA 106 compliance.
One commenter stated that most DOTs strive for consistency and
implement NEPA requirements on all projects, which ensures compliance
with federal regulations and allows previously non-
[[Page 2758]]
federal aid projects to become federal aid projects when additional
federal funds become available. One commenter suggested that if this
proposal is enacted, the Corps should provide specific standards for
professional qualifications similar to 36 CFR part 61, Appendix A. The
Corps is retaining the PCN requirements for federal permittees, so it
declines to speculate on how it would implement the proposal.
One commenter stated that to the extent there is a perception of
delay caused through federal administrative shortfalls and backlogs, a
greater level of funding for Corps staff and offices would be a better
investment in reducing perceived delays. This commenter said that
exchanging one federal staff funding shortfall for another agency with
less expertise would not produce a net gain in permitting efficiency
while complying with the duty to authorize only those impacts that will
have minimal adverse effects on the environment. One commenter
suggested that the Corps evaluate whether a PCN requirement should be
based on qualifications rather than the federal status of a permittee.
This commenter said that an audit process could be implemented to
verify past and continued quality of the applicant's work. One
commenter suggested the Corps focus on how to improve staff training
and the mechanics of the PCN process so that it is completed in a
reliable, transparent, and effective manner within the designated time
frames. The Corps is retaining the PCN requirements for federal
permittees, so these concerns have been addressed.
E. Comments on Regional Conditioning of Nationwide Permits
Under Section 404(e) of the Clean Water Act, NWPs can only be
issued for those activities that result in no more than minimal
individual and cumulative adverse environmental effects. For activities
that require authorization under Section 10 of the Rivers and Harbors
Act of 1899 (33 U.S.C. 403), the Corps' regulations at 33 CFR 322.2(f)
have a similar requirement. Since it can be difficult for the Corps to
draft national NWPs in such a way that they account for regional
differences, an important mechanism for ensuring compliance with these
requirements is regional conditions imposed by division engineers to
address local environmental concerns. Effective regional conditions
help protect local aquatic ecosystems and other resources and help
ensure that the NWPs authorize only those activities that result in no
more than minimal individual and cumulative adverse effects on the
environment and are not contrary to the public interest.
Corps regional conditions are added to the NWPs by division
engineers in accordance with the procedures at 33 CFR 330.5(c). Water
quality certification (WQC) and Coastal Zone Management Act (CZMA)
consistency concurrence regional conditions are also added to the NWPs
if an appropriate certifying authority issues a water quality
certification or CZMA consistency concurrence with special conditions
prior to the finalization of the issued, reissued, or modified NWPs.
Corps regional conditions approved by division engineers cannot
remove or reduce any of the terms and conditions of the NWPs, including
general conditions. Corps regional conditions cannot lessen PCN
requirements. In other words, Corps regional conditions can only be
more restrictive than the NWP terms and conditions established by Corps
Headquarters when it issues or reissues an NWP.
The Corps' regulations for establishing WQC regional conditions for
the NWPs are located at 33 CFR 330.4(c)(2). If, prior to the issuance
or reissuance of NWPs, a state, authorized tribe, or EPA issues a Clean
Water Act section 401 water quality certification with conditions, the
division engineer will make those water quality certification
conditions regional conditions for the applicable NWPs, unless he or
she determines that a specific condition in a water quality
certification issued for the issuance of an NWP does not comply with 40
CFR 121.7(d)(2). If the district engineer makes such a determination,
then he or she will consider that condition waived under 40 CFR
121.9(b) after written notice is provided to EPA and the certifying
authority consistent with 40 CFR 121.9(c). For more information on
compliance with Section 401 of the CWA, refer to Section III.G.
For CZMA consistency concurrences issued by a state for the
issuance of an NWP, if the division engineer determines those CZMA
concurrence conditions do not comply with 33 CFR 325.4, then the
conditioned CZMA consistency certification will be considered an
objection, and the project proponent will need to request an activity-
specific CZMA consistency concurrence from the state (see 15 CFR
930.31(d)) under subpart D of 15 CFR part 930.
Corps regional conditions may be added to NWPs by division
engineers after a public notice and comment process and coordination
with appropriate federal, state, and local agencies, as well as tribes.
After Corps Headquarters publishes in the Federal Register the proposal
to issue, reissue, or modify NWPs, all district engineers issue local
public notices to advertise the availability of the proposed rule in
the Federal Register and to solicit public comment on proposed regional
conditions and/or proposed revocations of NWP authorizations for
specific geographic areas, classes of activities, or classes of waters
(see 33 CFR 330.5(b)(1)(ii)).
As discussed above, regional conditions are an important tool for
taking into account regional differences in aquatic resources and their
local importance and for ensuring that the NWPs comply with the
requirements of Section 404(e) of the Clean Water Act, especially the
requirement that activities authorized by NWPs may only result in no
more than minimal individual and cumulative adverse environmental
effects. Regional conditions are modifications of the NWPs that are
made by division engineers. Regional conditions can only further
condition or restrict the applicability of an NWP (see 33 CFR
330.1(d)). Under 33 CFR 330.5(c)(1)(i), the first step of the Corps'
regional conditioning is for district engineers to issue public notices
announcing proposed regional conditions, and to solicit public comment
on those proposed regional conditions, usually for a 45-day comment
period. Those public notices also solicit suggestions from interested
agencies and the public on additional regional conditions that they
believe are necessary to ensure that the NWPs authorize only those
activities that have no more than minimal adverse environmental
effects. The district public notices are generally issued shortly after
Corps Headquarters publishes the proposed NWPs in the Federal Register.
After the public comment period ends for the district public
notices, the Corps district evaluates the comments and begins preparing
the supplemental documents required by 33 CFR 330.5(c)(1)(iii) for each
NWP. Each supplemental document will evaluate a specific NWP on a
regional basis (e.g., by Corps district geographic area of
responsibility or by state) and discuss the need for regional
conditions for that NWP. Each supplemental document will also include a
statement by the division engineer that will certify that the NWP, with
approved regional conditions, will authorize only those activities that
will have no more than minimal individual and cumulative adverse
environmental effects. The supplemental documents may cover a
[[Page 2759]]
Corps district, especially in cases where the geographic area of
responsibility for the Corps district covers an entire state. The
supplemental documents may cover a state when there is more than one
Corps district in the state, and the lead Corps district for that state
is responsible for preparing the supplemental documents. If more than
one Corps district operates in a state, the lead district is
responsible for preparing the supplemental documents and coordinating
with the other Corps districts. The supplemental documents include an
evaluation of public and agency comments, with responses to those
comments, to show that the views of potentially affected parties were
fully considered (33 CFR 330.5(c)(1)(ii)). The supplemental document
also includes a statement of findings demonstrating how substantive
comments were considered. After the supplemental documents are drafted
by the district, they are sent to the division engineer for review
along with the district's recommendations for regional conditions. The
division engineer may approve the supplemental documents or request
changes to those supplemental documents, including changes to the
regional conditions recommended by the district.
After the division engineer approves the regional conditions and
signs the supplemental documents, the district issues a public notice
on its website announcing the final Corps regional conditions and when
those regional conditions go into effect (see 33 CFR 330.5(c)(1)(v)).
Copies of the district's public notice are also sent to interested
parties that are on the district's public notice mailing list via email
or the U.S. mail. The public notice will also describe, if appropriate,
a grandfathering period as specified by 33 CFR 330.6(b) for those who
have commenced work under the NWP or are under contract to commence
work under the NWP (see 33 CFR 330.5(c)(1)(iv)). A copy of all Corps
regional conditions approved by the division engineers for the NWPs are
forwarded to Corps Headquarters (see 33 CFR 330.5(c)(3)).
Under the current regulations, Corps Headquarters does not have a
formal role in the development and approval of Corps' regional
conditions by division engineers. However, Corps Headquarters provides
templates for the supplemental documents required by Sec.
330.5(c)(1)(iii), to promote consistency in those supplemental
documents. If requested by district and division offices, Corps
Headquarters also provides advice on appropriate Corps regional
conditions for the NWPs. The Corps is a highly decentralized
organization, with most of the authority for administering the
regulatory program delegated to the 38 district engineers and 8
division engineers (see 33 CFR 320.1(a)(2)). District engineers are
responsible for the day-to-day implementation of the Corps Regulatory
Program, including the evaluation of applications for individual
permits, evaluating PCNs for proposed NWP activities, evaluating
notifications for activities authorized by regional general permits,
responding to requests for approved and preliminary jurisdictional
determinations, conducting compliance and enforcement actions, and
other tasks. Division engineers are responsible for overseeing
implementation of the Regulatory Program by their districts, and making
permit decisions referred to them by district engineers under the
circumstances identified in 33 CFR 325.9(c). Under that section of the
Corps' regulations, a division engineer can refer certain permit
applications to the Chief of Engineers for a decision. Other than
making permit decisions under the circumstances listed in Sec.
325.9(c), Corps Headquarters is responsible for development of
regulations, guidance, and policies.
When a state, authorized tribe, or EPA issues a WQC for the
issuance of an NWP and that WQC includes conditions, those conditions
become conditions of the NWP authorization, unless one or more
conditions is waived because they do not meet the criteria at 40 CFR
121.7(d)(2). The processes for states, approved tribes, and EPA to
issue WQCs for the issuance of the NWPs, are separate from the Corps'
regional conditioning process under 33 CFR 330.5(c), and are governed
by state, tribal, or EPA, regulations. The Corps' current regulations
for water quality certification for the NWPs are found at 33 CFR
330.4(c), and those regulations provide a process for WQC conditions
becoming conditions of the NWPs when WQCs are issued for the NWPs
before the NWPs are issued by Corps Headquarters.
When a state issues a general CZMA consistency concurrence with
conditions for an NWP, those conditions become CZMA regional conditions
if, after recommendation by the district engineer, the division
engineer determines those conditions are acceptable under 33 CFR
330.4(d)(2). The processes for states to issue general CZMA consistency
concurrences for the NWPs, are separate from the Corps' regional
conditioning process under 33 CFR 330.5(c), and are governed by
Department of Commerce regulations.
When the final WQCs and CZMA consistency concurrences are issued,
District and division engineers will review those WQCs and CZMA
consistency concurrences and determine which conditions become
conditions for the final NWPs. Division engineers will then finalize
any Corps regional conditions. After division engineers finalize Corps
regional conditions, Corps districts will issue public notices
announcing the final regional conditions and the final WQCs and CZMA
consistency concurrences for the issuance of the NWPs. The Corps will
post copies of the district public notices announcing the final Corps
regional conditions and final WQC/CZMA conditions in the
regulations.gov docket (docket number COE-2020-0002), under
``Supporting and Related Material.''
At present, districts manage their own processes for soliciting
public comment on their regional conditions. In general, they make
solicitations of public comment available on their own website and do
not always make the comments they receive publicly available. To
further improve the nationwide transparency of the regional
conditioning process, the Corps is considering revising the regulations
governing the regional conditioning process at 33 CFR 330.5(c).
Specifically, the Corps is considering whether to require the districts
to post and solicit public comment on notices proposing regional
conditions in separate dockets at www.regulations.gov. Even though such
changes were outside the scope of this action, the Corps solicited
public comment on whether to implement this or a similar requirement
relating to the regional conditioning process and any factors we should
consider in a future rulemaking. While the comments relate to matters
that were outside the scope of this action, the Corps appreciates the
helpful suggestions it received from the public. The Corps will
consider them as we continue to examine whether changes may be
necessary to the regulations governing the regional conditioning
process.
Several commenters said that regional conditions are excessive and/
or unnecessary. Several commenters requested that Corps Headquarters
review and concur with regional conditions before they are finalized. A
few commenters said that regional conditions may be appropriate in some
cases in specific areas of the country. A few commenters said that
rationale and justification for regional conditions should be made
available to the public. A few commenters recommended that Corps
Headquarters provide detailed
[[Page 2760]]
guidance to district offices regarding how to develop regional
conditions. A few commenters said that Corps districts are inconsistent
on how they create regional conditions. A couple of commenters said
that current regional conditions should not change. One commenter said
that regional conditions should be specific to watersheds or ecoregions
and not differ between districts.
The Corps believes that regional conditions are necessary to tailor
the NWPs on a regional basis to ensure that the NWPs authorize only
those activities that result in no more than minimal individual and
cumulative adverse environmental effects. Under the Corps' current
regulations at 33 CFR 330.5(c), division engineers have the authority
to add regional conditions to the NWPs and Corps Headquarters has no
role in that approval process. The supplemental documents division
engineers prepare for adding regional conditions to the NWPs require
consideration of the comments received on the district's public notices
on the proposed regional conditions and a statement of findings showing
how substantive comments were considered by the division engineer (see
33 CFR 330.5(c)(1)(iii)). Regional conditions do not need to be
consistent across districts, among divisions, or nationally because
they are intended to address specific regional issues or concerns for
the aquatic environment or any of the Corps' public interest review
factors. If regional conditions are specific to watersheds, differences
in regional conditions among districts are inevitable because different
watersheds are likely to have different resource concerns and different
factors affecting what adverse environmental effects might be
considered more than minimal.
One commenter stated that Corps districts should be able to develop
and identify appropriate regional conditions. One commenter said that
the proposed changes to regional conditions will remove coordination
processes with state partners. One commenter remarked that the proposed
changes will result in a disproportionate impact to floodplains and
flood-prone areas. One commenter said that the regional conditions for
NWPs 12, C, and D should be the same in each region. One commenter
stated that there is inconsistency between whether or not Corps
districts consider oil and gas natural pipelines as utility lines in
regional conditions.
Corps districts identify regional conditions, and make
recommendations to division engineers. The approval authority for
regional conditions lies with the division engineer (see 33 CFR
330.5(c)). Regional conditions can provide for coordination with state
partners, and that coordination may be removed as regional conditions
are considered for a new set of NWPs. The Corps does not have the
authority to regulate floodplains and flood-prone areas per se. The
Corps has the authority to regulate discharges of dredged or fill
material into waters of the United States, and those waters and
proposed discharges may be located in floodplains or flood-prone areas.
Having identical regional conditions for NWPs that authorize utility
line activities would be contrary to the intent of regional conditions,
which is to address regional differences in aquatic resources and
ensure that the NWPs authorize only those activities that result in no
more than minimal individual and cumulative adverse environmental
effects. Oil and natural gas pipelines are a type of utility line and
regional conditions are intended to address specific resource concerns.
One commenter said that regional conditions should include
programmatic compliance with other federal laws. One commenter stated
that regional conditions should be used to require in-kind mitigation
and adopt impact and mitigation thresholds or associated methodologies.
One commenter said that regional conditions should be developed to
provide additional protection for species of concern and cultural/
historical sites. One commenter asserted that regional conditions
should be developed to require tribal consultation for every permit.
One commenter said that regional conditions should prohibit work during
spawning period for fish of cultural concern or which would jeopardize
wild rice beds.
Regional conditions may be helpful in ensuing programmatic
compliance with other federal laws. Regional conditions can also be
used to specify mitigation requirements for the NWPs. Regional
conditions can help provide protection for listed species, historic
properties, and cultural resources, often by adding PCN requirements to
help ensure that required consultations for those resources are
undertaken. Decisions on whether and how to consult with tribes on
proposed NWP activities are made on a case-by-case basis by district
engineers. Regional conditions may add time-of-year restrictions on
authorized activities to ensure that those activities have no more than
minimal adverse effects on fish spawning or rice beds.
Several commenters requested greater transparency in the process of
establishing regional conditions, saying that public notices,
rationales for regional conditions, and comments received on proposed
regional conditions should be available on separate dockets at
www.regulations.gov. Several commenters requested revisions to
governing regulations to require posting of any proposed additions of,
changes to, or revocations of regional conditions in separate dockets
on www.regulations.gov. Several commenters requested that the Corps
create and maintain a single, national website where all proposed and
final regional conditions can be viewed. The Corps will consider these
comments when it prepares the next rulemaking for the issuance of NWPs.
A few commenters said that public notice processes for regional
conditions should be consistent between districts. A few commenters
stated that districts are inconsistent and limit comment by requiring
subscriptions to respective mailing lists rather than publishing
notices in the Federal Register or on www.regulations.gov. One
commenter said that public notices for regional conditions should be
published in the Federal Register. Two commenters asked for the same
level of written justification for adoption of regional conditions that
is required to reissue or modify the NWPs. One commenter said that
publication of these documents on separate web pages or dockets is
redundant and unnecessary. One commenter stated that that comments
received on regional conditions should be posted to a web page. One
commenter stated that the Corps analyses for regional conditions do not
satisfy statutory requirements. Two commenters said that it is
difficult to find public notices or regional conditions on district web
pages.
The public notice process for regional conditions is consistent
among all Corps districts, because the public notice process is
described in the Corps' regulations at 33 CFR 330.5(c)(1). The current
regulations governing the regional conditioning process relies on
public notices, and does not include provisions requiring the
publication of notices in the Federal Register. During the next
rulemaking process for the NWPs, the Corps will decide whether to use
www.regulations.gov for managing and posting public comments received
on proposed regional conditions. Each Corps district is responsible for
managing its own web pages, and regional conditions apply to a
particular Corps district, so it is appropriate for Corps districts to
post public notices for regional conditions proposed for their
districts on their web pages.
[[Page 2761]]
F. Comments on Proposed Removal of the 300 Linear Foot Limit for Losses
of Stream Bed
In the proposed rule, the Corps proposed to remove the 300 linear
foot for losses of stream bed from NWPs 21 (Surface Coal Mining
Activities), 29 (Residential Developments), 39 (Commercial and
Institutional Developments), 40 (Agricultural Activities), 42
(Recreational Facilities), 43 (Stormwater Management Facilities), 44
(Mining Activities), 50 (Underground Coal Mining Activities), 51 (Land-
Based Renewable Energy Generation Facilities), and 52 (Water-Based
Renewable Energy Generation Pilot Projects). All of these NWPs have a
\1/2\-acre limit for losses of non-tidal waters of the United States,
including non-tidal wetlands and non-tidal streams. With the exception
of NWPs 43 and 51, these NWPs require pre-construction notification for
all activities. Nationwide permit 43 does not require PCNs for
maintenance of existing stormwater management facilities, as long as
those maintenance activities are limited to restoring the original
design capacities of the stormwater management facility or pollutant
reduction green infrastructure feature. Nationwide permit 51 does not
require PCNs for activities that result in the loss of \1/10\-acre or
less of waters of the United States. Therefore, district engineers will
review all proposed activities for these on a case-by-case basis,
except for the NWP 43 and 51 activities identified above. When
reviewing these PCNs, district engineers apply the 10 criteria in
paragraph 2 of Section D, District Engineer's Decision, to determine
whether the proposed activities will result in no more than minimal
individual and cumulative adverse environmental effects.
In the proposed rule, the Corps presented a number of reasons for
these proposed changes to NWPs 21, 29, 39, 40, 42, 43, 44, 50, 51, and
52. The Corps' rationale comprises four categories of considerations:
(1) The Corps employs several tools in the NWP Program to ensure that
NWP activities result only in no more than minimal individual and
cumulative adverse environmental effects; (2) removing the 300 linear
foot limit would provide consistency across the numeric limits used by
the NWP Program for all categories of non-tidal waters of the United
States (i.e., jurisdictional wetlands, streams, ponds, and other non-
tidal waters); (3) it would further the objective of the NWP Program
stated in 33 CFR 330.1(b) (i.e., to authorize with little, if any,
delay or paperwork certain activities having minimal impacts), by
providing equivalent quantitative limits for jurisdictional wetlands,
streams, and other types of non-tidal jurisdictional waters, and NWP
authorization for losses of jurisdictional stream bed that have no more
than minimal individual and cumulative adverse environmental effects;
and (4) using acres or square feet (i.e., an area-based metric) instead
of linear feet is a more accurate approach to quantifying losses of
stream bed and also serves as a better surrogate for losses of stream
functions when a functional assessment method is not available or
practical to use.
After reviewing the comments received in response to the proposed
rule, for the reasons discussed below the Corps has decided to remove
the 300 linear foot limit for losses of stream bed from the 10 NWPs
listed above. The comments received in response to the proposed rule
are summarized below. The Corps' responses to those comments are also
provided along with the comment summaries.
Retaining the \1/2\-acre limit for losses of non-tidal
jurisdictional waters and wetlands in these 10 NWPs while removing the
300 linear foot limit for losses of stream bed will help further
Congressional intent with respect to Section 404(e) of the Clean Water
Act when that provision was enacted into law in 1977. Section 404(e)
authorizes the Corps to issue, after notice and opportunity for public
hearing, general permits on a state, regional, or nationwide basis for
any category of activities involving discharges of dredged or fill
material if the Corps determines that the activities in such category
are similar in nature, will cause only minimal adverse environmental
effects when performed separately, and will have only minimal
cumulative adverse effect on the environment. Section 404(e) does not
prescribe any particular approaches for ensuring that activities
authorized by general permits result in no more than minimal individual
and cumulative adverse environmental effects, thus the Corps developed
the PCN process and provided division and district engineers with the
authority to modify, suspend, or revoke NWP authorizations on a
regional or activity-specific basis after the NWPs are issued by Corps
Headquarters. General permits provide a process for authorizing, with
minimal paperwork and delays, activities that have no more than minimal
individual and cumulative adverse environmental effects. General
permits are an important tool for the Corps managing its personnel and
workload so that it can focus its efforts on evaluating permit
applications for proposed activities that have the potential to cause
more than minimal adverse environmental effects.
Removing the 300 linear foot limit for losses of stream bed under
these 10 NWPs provides equivalent quantitative limits for all
categories of non-tidal jurisdictional waters, including non-tidal
``tributaries,'' ``lakes, ponds, and impoundments of jurisdictional
waters,'' and ``adjacent wetlands'' (see 33 CFR 328.3(a)). These non-
tidal waters will continue to be subjected to the \1/2\-acre limit for
losses of non-tidal waters. Except for NWPs 43 and 51, these NWPs
require PCNs for all authorized activities, and district engineers will
review these PCNs to determine which activities can be authorized by an
NWP and which activities should require individual permits. When
reviewing a PCN, the district engineer has the authority to exercise
discretionary authority to modify, suspend, or revoke the NWP
authorization (see 33 CFR 330.1(d)). When a district engineer reviews a
PCN, and if she or he determines that the proposed activity would have
more than minimal individual or cumulative net adverse effects on the
environment or otherwise may be contrary to the public interest, he or
she will either modify the NWP authorization to reduce or eliminate
those adverse effects, or instruct the prospective permittee to apply
for a regional general permit or an individual permit (Sec. 330.1(d)).
To determine whether a proposed NWP activity will result in no more
than minimal individual and cumulative adverse environmental effects,
the district engineer will apply the 10 criteria in paragraph 2 of
Section D, District Engineer's decision.
Those ten criteria for making minimal adverse environmental effects
determinations are:
(1) The direct and indirect effects caused by the NWP activity;
(2) the cumulative adverse environmental effects caused by
activities authorized by an NWP and whether those cumulative adverse
environmental effects are no more than minimal;
(3) the environmental setting in the vicinity of the NWP activity;
(4) the type of resource that will be affected by the NWP activity;
(5) the functions provided by the aquatic resources that will be
affected by the NWP activity;
(6) the degree or magnitude to which the aquatic resources perform
those functions;
(7) the extent that aquatic resource functions will be lost as a
result of the
[[Page 2762]]
NWP activity (e.g., partial or complete loss);
(8) the duration of the adverse effects (temporary or permanent);
(9) the importance of the aquatic resource functions to the region
(e.g., watershed or ecoregion); and
(10) mitigation required by the district engineer.
If an appropriate functional assessment method is available and
practicable to use, that assessment method may be used by the district
engineer to help determine whether the proposed activity will result in
no more than minimal adverse environmental effects.
The removal of the 300 linear foot limit for losses of stream bed
will help increase administrative efficiency by providing a mechanism
to authorize, through the NWP Program activities that result in the
loss of greater than 300 linear feet of jurisdictional stream bed, but
less than \1/2\-acre of non-tidal jurisdictional waters. Under the 2017
NWPs, filling or excavating more than 300 linear feet of a perennial
stream bed requires an individual permit even under circumstances where
the loss of the stream bed would result in no more than minimal
individual and cumulative adverse environmental effects. Under this
final rule, district engineers would review PCNs for proposed losses of
jurisdictional stream bed (plus any other losses of non-tidal waters of
the United States) that are less than \1/2\-acre and determine whether
those proposed activities can be authorized by one of these 10 NWPs.
If, for a particular PCN, the district engineer determines that the
individual and cumulative adverse environmental effects would be more
than minimal, he or she will exercise discretionary authority and
require an individual permit. This approach provides administrative
efficiency by providing a mechanism for district engineers to
distinguish which proposed activities should be authorized by an NWP
versus which activities should require individual permits with a public
notice and comment process and activity-specific evaluations under
NEPA, the public interest review, and the Clean Water Act section
404(b)(1) Guidelines.
This approach also adds efficiency in terms of reducing processing
times and paperwork for proposed activities that have no more than
minimal adverse environmental effects and that are likely to generate
few, if any, public or agency comments in response to a public notice
for an individual permit application. When more activities that result
in no more than minimal adverse environmental effects can be authorized
by an NWP, there can be more staff and other resources for Corps
districts to devote to undertaking other tasks, such as the review and
approval of mitigation banks and in-lieu fee programs and overseeing
their operation, conducting compliance actions to ensure that
authorized activities are being conducted in accordance with the terms
and conditions of their DA authorizations, and conducting approved and
preliminary jurisdictional determinations that help project proponents
plan and design their proposed projects to avoid and minimize impacts
to jurisdictional waters and wetlands.
Another benefit of removing the 300 linear foot limit for losses of
jurisdictional stream bed and shifting the quantification of losses of
jurisdictional stream bed towards the \1/2\-acre limit for losses of
non-tidal waters of the United States is more accurate accounting of
the impacts of activities authorized by these 10 NWPs. The discharges
of dredged or fill material authorized by these NWPs occur over an area
of a river or stream bed and also may include impacts to other aquatic
resources such as wetlands or open water areas (e.g., lakes or ponds).
The discharge to a river or stream has a length and a width, and the
width can vary depending on the physical characteristics of the impact
area, the type of activity being conducted (e.g., bank stabilization,
channel excavation, channel realignment), and other factors. To be
regulated under Section 404 of the Clean Water Act, a discharge of
dredged material involves any addition, including redeposit other than
incidental fallback, of dredged material, including excavated material,
into waters of the United States that is incidental to any activity,
including mechanized land clearing, ditching, channelization, or other
excavation (see 33 CFR 323.2(d)(1)(iii)). A regulated discharge of fill
material involves the addition of fill material into waters of the
United States that has the effect of either replacing any portion of a
water of the United States with dry land or changing the bottom
elevation of any portion of a water of the United States (see 33 CFR
323.3(e) and (f)). The direct impacts of these activities are most
accurately quantified on an area basis, not a linear basis, to inform a
district engineer's decision on whether a proposed activity should be
or is authorized by an NWP and to track cumulative impacts.
Accurate quantification of stream bed losses authorized by an NWP
is an important component of determining whether a proposed NWP
activity will result in no more than minimal individual adverse
environmental effects. (See item 1 above from paragraph 2 of Section D,
District Engineer's Decision: Understanding ``the direct and indirect
effects caused by the NWP activity.'') Accurate quantification of
stream bed losses is also important for tracking cumulative impacts of
activities authorized by an NWP, both on a national and regional basis,
and for determining whether a particular NWP activity will contribute
to more than minimal cumulative adverse environmental effects. (See
item 2 of paragraph 2 of the District Engineer's Decision: ``The
cumulative adverse environmental effects caused by activities
authorized by an NWP and whether those cumulative adverse environmental
effects are no more than minimal.'')
As discussed in the 2020 Proposal (85 FR 57316), discharges of
dredged or fill material into jurisdictional streams can cause losses
of stream bed along only a portion of the stream bed (e.g., bank
stabilization projects that involve discharging fill along the edge of
the stream, with no fill in the rest of the stream bed) or across the
entire stream bed (e.g., excavating the stream bed to mine aggregates)
along a stream reach. A wide variety of activities involving filling or
excavating stream bed may be authorized by these NWPs, such as bank
stabilization, channel realignment, culvert installation or
replacement, stream channel restoration, the installation of grade
control structures (e.g., rock), fills for footings for bridges,
livestock crossings, utility line crossings, and temporary fills for
construction and access. Quantifying losses of stream bed in linear
feet does not distinguish between filling or excavation activities that
occur only in a portion of the stream bed along an ordinary high water
mark versus filling or excavation activities that occur in the entire
stream bed, from ordinary high water mark to ordinary high water mark.
Accurate quantification of losses of stream bed and losses of other
types of jurisdictional waters and wetlands is also important for
monitoring and evaluating the cumulative adverse environmental effects
caused by NWP activities. In response to the 2020 Proposal, numerous
commenters criticized the Corps' assessment of cumulative effects for
the NWPs. An essential step in conducting a cumulative effects analysis
for an NWP is estimating how many times that NWP may be used during the
period the NWP is in effect, the quantity of jurisdictional waters and
wetlands that may be lost or
[[Page 2763]]
directly altered by the activities authorized by that NWP, whether
those losses or alterations are permanent or temporary, and what, if
any compensatory mitigation is being used to offset those losses. The
Corps provides those estimates in its national decision documents, and
those estimates are more robust if they use a common metric, so that it
is possible to calculate total losses and offsets during the period the
NWP is in effect.
Division engineers have discretionary authority to modify, suspend,
or revoke NWP authorizations on a regional basis (33 CFR 330.5(c)) to
help ensure that the NWPs are only used to authorize activities that
have no more than minimal individual and cumulative adverse
environmental effects. For example, if a Corps district determines, in
a particular watershed, county, Corps district, or other geographic
region, that cumulative losses of stream bed authorized by NWPs may be
approaching a level that might exceed the ``no more than minimal
cumulative adverse environmental effects'' threshold, the Corps
district can request that the division engineer modify, suspend, or
revoke the relevant NWP authorizations in that region. The division
engineer can add regional conditions to the appropriate NWPs to
restrict or prohibit their use in particular categories of waters, or
suspend or revoke the NWP authorization so that those NWP(s) can no
longer be used to authorize regulated activities in that geographic
region. The division engineer's authority to modify, suspend, or revoke
NWP authorizations on a regional basis can also be used to sort out
which activities can be authorized by an NWP versus which activities
should require individual permits.
District engineers have discretionary authority to modify, suspend,
or revoke NWP authorizations on a case-specific basis (see 33 CFR
330.5(d)) to help ensure that NWPs are only used to authorize specific
activities that have no more than minimal individual and cumulative
adverse environmental effects. A district engineer can add conditions
to an NWP authorization to reduce potential adverse environmental
effects that might be caused by a proposed NWP activity, such as
mitigation requirements to avoid or minimize direct and indirect
effects caused by that activity. One example is a time of year
restriction to prevent discharges of dredged or fill material from
occurring during spawning seasons for fish or other aquatic organisms.
Another example of a permit conditions to help reduce adverse
environmental effects caused by an NWP activity might be to require the
use of certain best management practices. A district engineer might
also add permit conditions to the NWP authorization to require
compensatory mitigation to offset losses of waters of the United States
caused by the NWP activity.
As the Corps implements this final rule, it will continue to rely
on these administrative tools that have long been used with these 10
NWPs to help ensure that authorized activities will result in no more
than minimal individual and cumulative adverse environmental effects.
Those tools are the \1/2\-acre limit for losses of non-tidal waters of
the United States, the pre-construction notification requirements and
associated activity-specific review by district engineers, the regional
conditions that can be added by division engineers, and the activity-
specific conditions that can be added by district engineers when
reviewing individual PCNs.
The proposal was made in accordance with the recommendations in the
report issued by the Office of the Assistant Secretary of the Army
(Civil Works) in response to E.O. 13783 on ways to streamline the NWPs.
In the proposed rule, the Corps invited public comment on the proposal
to remove the 300 linear foot limit and to rely on the \1/2\-acre
limit, the PCN process, the proposed modification of the ``mitigation''
general condition (general condition 23), and other tools to comply
with the statutory and regulatory requirement that activities
authorized by an NWP must result in no more than minimal individual and
cumulative adverse environmental effects. The Corps also invited
comment on whether there are situations where quantifying losses of
stream bed in linear feet might more accurately represents the actual
amount of stream bed filled or excavated as a result of an NWP activity
and would result in more defensible determinations on whether a
proposed NWP activity will result in no more than minimal individual
and cumulative adverse environmental effects. In the proposed rule, the
Corps asked commenters to provide information that would help
illustrate or explain how and under what circumstance using a linear
foot measure to quantify losses of stream bed would be more accurate
than using square feet or acres to quantify the amount of authorized
impacts.
The Corps also invited comment on the legal, regulatory, policy, or
scientific bases for imposing different numeric limits on
jurisdictional stream bed losses versus losses of non-tidal
jurisdictional wetlands or other types of non-tidal jurisdictional
waters. Commenters were encouraged to provide supporting information in
the form of citations to laws, regulations, and policies, and the
scientific literature, because substantive information would be
valuable in assisting the Corps in preparing the final NWPs.
The Corps also requested comment on an alternative hybrid approach
to establishing consistent quantitative limits for losses of stream bed
authorized by NWPs 21, 29, 39, 40, 42, 43, 44, 50, 51, and 52. Under
the proposed hybrid approach, losses of stream bed would continue to be
quantified in linear feet as long as the activities authorized by these
NWPs would result only in the loss of stream bed. There would be linear
foot limits for losses of stream bed by stream order identified using
the Strahler (1957) method, and the mean stream widths identified by
Downing et al. (2012). If a proposed NWP activity would result in the
loss of jurisdictional stream bed plus other types of waters of the
United States, such as non-tidal jurisdictional wetlands, the losses of
waters of the United States would be quantified in acres and subjected
to the \1/2\-acre limit. In the preamble to the proposed rule, the
Corps provided a table for the hybrid approach (see 85 FR 57321). A
critical component of effectively applying the hybrid approach is
identifying the correct stream order for the stream segment that is
proposed to be filled or excavated as a result of the proposed NWP
activity. In this hybrid approach, the linear foot limits would only
apply to losses of stream bed. If a proposed NWP activity would result
in a combination of losses of jurisdictional stream bed and other types
of waters of the United States, such as non-tidal jurisdictional
wetlands, then the \1/2\-acre limit would apply to the combined losses
of stream bed and non-tidal wetlands, to keep those losses below \1/2\-
acre.
In conjunction with the proposal to remove the 300 linear foot
limit for losses of stream bed, the Corps proposed to remove the
provisions in these NWPs regarding the ability of district engineers to
waive the 300 linear foot limit for losses of intermittent and
ephemeral stream bed when the applicant submits a PCN and requests a
waiver of that 300 linear foot limit. On April 21, 2020, EPA and the
Department of the Army published a final rule to define ``waters of the
United States'' entitled the Navigable Waters Protection Rule (85 FR
22250). On June 22, 2020, the Navigable Waters Protection Rule became
effective in all states and jurisdictions except for the State of
Colorado due to a federal
[[Page 2764]]
district court-issued stay in that state. The rule revised the
definition of ``waters of the United States'' at 33 CFR 328.3 such that
ephemeral features, including ephemeral streams, are categorically
excluded from jurisdiction under the Clean Water Act (see 33 CFR
328.3(b)(3)). Therefore, there would be no need to request waivers for
losses of ephemeral stream bed (regardless of length) since NWP
authorization (or any other form of DA authorization) will not be
needed to authorize discharges of dredge or fill material into
ephemeral streams. See Section III.C, for more discussion on the
potential impact of the Navigable Water Protection Rule on the NWPs.
In addition, the Corps proposed to remove the agency coordination
process for seeking input from federal and state agencies on whether
the district engineer should grant the waiver of the 300 linear foot
limit requested by an applicant for an NWP verification. Removing the
waiver provision may reduce costs to permittees by reducing the amount
of time the district engineer needs to make her or his decision. For
example, the district engineer would not have to wait up to 25 days
(see paragraph (d)(3) of the ``pre-construction notification'' general
condition (GC 32) to make the decision on whether to issue the NWP
verification. Removal of the agency coordination for these activities
is also likely to reduce administrative costs to the Corps, by reducing
the amount of staff time needed to send copies of PCNs to the agencies
and summarizing and responding to agency comments. Removal of the
waiver provision and associated agency coordination would also free up
additional time for Corps staff to review other PCNs, other permit
applications, and other regulatory actions such as jurisdictional
determinations and compliance activities. As mentioned above, under the
Navigable Waters Protection Rule, ephemeral streams are not ``waters of
the United States.'' See 33 CFR 328.3(b)(3). Therefore, it should be
noted that this would likely reduce the current number of waivers and
required interagency coordination process from state and federal
agencies, since the current waivers apply only to certain intermittent
streams.
Many commenters opposed the removal of the 300 linear foot limit
for losses of stream bed. Many commenters supported the proposed
change, stating that calculating losses of stream bed in acres is a
more accurate measure of those losses since acreage takes both the
length and width of the stream channel into account when determining
the amount of stream bed filled or excavated by an NWP activity.
Several commenters in favor of the proposed change expressed concern
with how this change would affect mitigation banks and credit
calculations for future and past permits. Several commenters believed
this change would continue to ensure that the activities authorized by
these NWPs would result in no more than minimal impacts.
As discussed above, the Corps is removing the 300 linear foot limit
for losses of stream bed from NWPs 21, 29, 39, 40, 42, 43, 44, 50, 51,
and 52 for the reasons discussed in this final rule to increase the
efficiency of the NWP program, utilize a metric that more accurately
reflects the amount of impact, and to allow NWP authorization of losses
of stream bed where district engineers determine that those losses
would have no more than minimal adverse environmental effects after
reviewing PCNs. Quantifying losses of stream bed in acres or square
feet will be more accurate, provide a more substantial and defensible
basis for decision-making by district engineers on PCNs for these
activities, and provide more accurate data for the Corps to track
cumulative impacts of the activities authorized by these NWPs. The
removal of the 300 linear foot limit will not affect the ability of
district engineers to require compensatory mitigation or other forms of
mitigation for losses of stream bed. In addition, it should not have a
substantial effect on mitigation banks that have already been approved
and mitigation banks that may be approved in the future. Depending on
how existing mitigation banks quantify the credits they produce, there
may have to be some technical changes in how credit transactions occur
between mitigation bank sponsors and permittees, to determine the
appropriate number of stream credits that are needed to offset a
permitted loss of stream bed.
A few commenters supported the removal of the 300 linear foot limit
because the district engineer retains the ability to exercise
discretionary authority to require individual permits if the adverse
environmental effects caused by a proposed activity would be more than
minimal. These commenters also said they support the removal of the 300
linear foot limit as long as Corps divisions and districts can continue
to develop and use regional conditions in districts that have specific
resource concerns.
The PCN process is an administrative tool that helps ensure that
activities authorized by NWPs cause no more than minimal individual and
cumulative adverse environmental effects, by providing activity-
specific review of these activities by district engineers before they
are authorized by an NWP. The \1/2\-acre limit is another tool that
helps ensure that activities authorized by these NWPs have no more than
minimal adverse environmental effects. In geographic areas where there
are concerns about cumulative losses of headwater streams and the
functions they provide, division engineers can add regional conditions
to these NWPs to reduce the acreage limit from \1/2\-acre to a lower
acreage limit, such as \1/4\-acre or \1/10\-acre. In addition, division
engineers can add regional conditions to these NWPs to lower the
threshold for requiring stream compensatory mitigation from \3/100\-
acre to a different acreage threshold.
Many commenters expressed concerns with removing the 300-linear
foot limit on loss of stream bed for these NWPs, stating that this
change would allow much larger impacts to smaller stream channels since
they typically have smaller widths and therefore a permittee could
impact a much longer length of stream before reaching the \1/2\-acre
limit. Many commenters said that a linear foot measurement was more
appropriate for calculating stream impacts and losses than an acreage-
based system because streams are fundamentally linear features in the
landscape. Many commenters stated that the Corps has not provided any
scientific rational or reasoning behind this change and even the
scientific studies cited by the Corps were not interpreted
appropriately.
As discussed above, the Corps will rely on other, existing
protective mechanisms within the NWPs to ensure that the activities
authorized by these NWPs will result in no more than minimal individual
and cumulative adverse environmental effects. Those tools include the
\1/2\-acre limit, the PCN requirements for these NWPs, and the ability
of division and district engineers to further condition or restrict the
applicability of an NWP in situations where they have concerns for the
aquatic environment under the Clean Water Act section 404(b)(1)
Guidelines or for any factor of the public interest (see 33 CFR
330.1(d)). While rivers and streams have a strong linear component,
they also vary substantially in width. Discharges of dredged or fill
material into waters of the United States that cause losses of waters
of United States through the filling or excavation of stream beds occur
over an area, and using acres or square feet to quantify losses of
stream bed is more informative to determinations of minimal effects and
[[Page 2765]]
accurate in data accounting than using linear feet. The potential
losses of stream functions, and whether those losses are more than
minimal, can be addressed through the PCN review process. When
determining whether a proposed NWP activity will result in no more than
minimal individual and cumulative adverse environmental effects,
district engineers will apply the 10 criteria in paragraph 2 of Section
D, District Engineer's Decision. Decisions regarding quantitative
limits for the NWPs are administrative decisions because the legal
threshold for general permits (``no more than minimal individual and
cumulative adverse environmental effects'') is a subjective threshold.
Applying this subjective threshold to complex ecological systems
requires a district engineer to exercise his or her judgment as to
whether that threshold is crossed for particular NWP activity.
Another tool that the Corps added to this final rule to help ensure
that the activities authorized by these NWPs will result in no more
than minimal individual and cumulative adverse environmental effects is
the addition of a \3/100\-acre threshold for stream compensatory
mitigation in paragraph (d) of the mitigation general condition
(general condition 23). The \1/10\-acre wetland mitigation threshold in
general condition 23 has been effective in providing incentives for
project proponents to reduce wetland losses well below the \1/2\-acre
limit to avoid the costs of providing wetland compensatory mitigation.
As shown in figure 5.1 of the Regulatory Impact Analysis for this final
rule, more than 80 percent of losses of waters of the United States
verified by district engineers in fiscal year 2018 as qualifying for
NWP authorization were less than \1/10\-acre. The losses of waters of
the United States in figure 5.1 include losses of stream bed, which
were quantified in acres. The Corps anticipates that the \3/100\-acre
stream compensatory mitigation threshold will also be an effective
incentive to permittees to reduce losses of stream bed to avoid the
costs of providing stream compensatory mitigation to offset losses of
greater than \3/100\-acre of stream bed. For NWP activities that
require PCNs, district engineers continue to have discretion to require
stream compensatory mitigation for losses of stream bed above or below
the \3/100\-acre threshold in paragraph (d) of general condition 23.
Several commenters also questioned the Corps' use of the study by
Downing et al. (2012), which examined stream channels all over the
world, stating that stream channels may be narrower in the United
States (citing an average width in the United States of 2.6 feet).
Several commenters stated support of a hybrid approach in lieu of an
acreage calculation, but were concerned about the variability of stream
order classifications and the availability of tools to Corps districts
to implement that approach in an effective and defensible manner. One
of these commenters noted that LiDAR is not available in all areas of
the country. Many commenters opposed the proposed `hybrid approach' in
the preamble in which stream impact limits would vary by stream order
by applying a mean stream width. Some of these commenters asserted that
a linear foot metric is still likely a more accurate and easier method
since determining stream order is highly varied along with determining
a stream width.
The Corps acknowledges that the study by Downing et al. (2012) does
not fully represent the variability in stream dimensions. One of the
purposes of using the information in that study was to demonstrate how
a linear foot limit for losses of stream bed results in disparate
differences in the amount of stream bed that can be filled or excavated
under an NWP depending on where an affected stream reach is located in
a tributary network (i.e., a headwater stream versus a stream segment
located further downstream in a watershed). In a study of headwater
streams in North America and New Zealand, using field surveys of
headwater streams instead of the published data and satellite imagery
used by Downing et al. (2012), Allen et al. (2018) found a typical
width of 1.05 feet for headwater streams. The Corps agrees that the
hybrid approach proposed in the preamble to the 2020 Proposal would not
be an efficient or effective approach to establishing quantitative
limits for these 10 NWPs. There is not sufficiently accurate mapping of
headwater streams in the United States to implement such a hybrid
approach, and the hybrid approach would not take into account regional
variability in stream geomorphology. The Corps does not agree that a
linear foot metric is easier or more accurate than an acreage-based
metric. The area of stream bed filled or excavated as a result of an
NWP activity is already calculated by the Corps to record impacts to
aquatic resources, and it represents the amount of stream bed lost as a
result the discharges of dredged or fill material regulated under
Section 404 of the Clean Water Act.
Many commenters also questioned how stream width was to be measured
(ordinary high water mark to ordinary high water mark versus stream
bed/bottom) which could also produce variability in how an acreage
limit would be applied. Many commenters recognized that the measures
for small and large streams should be different but until a more
appropriate metric is developed, acreage should not be used in lieu of
linear feet since it would be inappropriate to adopt a measure that
better represents larger stream systems while the overwhelming majority
of impacts occur to smaller streams and are therefore better
represented for the time being by a linear foot measurement.
Stream width should be measured from ordinary high water mark to
ordinary high water mark, perpendicular to the longitudinal direction
of the stream channel. That is consistent with the definition of
``stream bed'' in Section F of the NWPs. Commenters did not suggest a
more accurate method for quantifying impacts to small and large streams
in their comments. Establishing different metrics for small versus
large streams also presents challenges in terms of consistently
determining what constitutes a small stream versus a large stream,
which has the potential for being an arbitrary distinction and would
add another layer of complexity to the NWP program.
Many commenters noted that smaller stream channels provide
important ecological functions and values and they provided numerous
references to scientific studies that document the importance of these
stream channels as linear systems in the landscape. Some of these
commenters said impacts to small stream channels were more severe and/
or permanent (e.g., complete losses by filling entire stream reaches)
and noted that small streams are more susceptible to fragmentation
impacts, are harder to restore/mitigate, and have compounding effects
to downstream waters when impacts are cumulative and more than minimal.
Many commenters noted that, in general, disproportionate impacts
already occur to these smaller order stream channels because it is
easier from an engineering standpoint and ultimately less costly to
impact them versus larger order stream channels, and that removing the
300 linear foot limit would provide even less incentive to avoid and
minimize impacts to these important resources.
The ecological functions of smaller stream channels are to be
considered by district engineers when they review PCNs for proposed
activities involving filling or excavating stream beds. When evaluating
PCNs, district engineers consider the 10 criteria in paragraph 2
[[Page 2766]]
or Section D, District Engineer's Decision. Those criteria include: The
environmental setting in the vicinity of the NWP activity, the type of
resource that will be affected by the NWP activity, the functions
provided by the aquatic resources that will be affected by the NWP
activity, the degree or magnitude to which the aquatic resources
perform those functions, the extent that aquatic resource functions
will be lost as a result of the NWP activity, and the importance of the
aquatic resource functions to the region. Division engineers can add
regional conditions to the NWPs to impose lower acreage limits or other
restrictions to address concerns about potential losses of smaller
stream channels and the functions they provide, including cumulative
impacts to those smaller stream channels. The Corps acknowledges that,
because of their size, smaller stream channels may be more susceptible
to proposed development activities and other activities involving
discharges of dredged or fill material into waters of the United
States. Project proponents are less likely to fill larger stream
channels because of the water that flows towards those larger stream
channels, but other activities such as bank stabilization, excavation
activities in the stream bed, and realigning stream channels may be
authorized by these NWPs. Removing the 300 linear foot limit and
relying on the \1/2\-acre limit and PCN review process to identify
activities that require individual permits helps the Corps implement
its permit program more effectively, to efficiently authorize
activities with no more than minimal adverse environmental effects via
NWP, and focusing more of its resources on evaluating individual permit
applications for activities that are likely have more substantial
environmental impacts.
Many commenters said that this change would allow more than minimal
impacts because of the disproportionate length of impacts to headwater
streams that would be allowed now under the NWP program, which is said
to be counter to and inconsistent with the goal and purpose of the NWP
program. Many commenters questioned how the Corps could reconcile and
justify this change based on the long-standing history of the 300-
linear foot limit for losses of stream bed in the NWP program. Many
commenters stated that individual permits should be required for
proposed impacts to more than 300 linear feet of stream bed, to allow
for the public and federal, state, and local resource agencies to
comment on proposals to fill or excavate several thousand feet of
stream bed.
The Corps will be relying on other, existing protective mechanisms
within the NWPs to ensure that these NWPs authorize only those
activities that have no more than minimal adverse environmental
effects. The NWP program has changed over time as new information is
considered and alternative ways of implementing the program are
identified to further the program's objective of regulating, ``with
little, if any, delay or paperwork certain activities having minimal
impacts'' (33 CFR 330.1(b)). The removal of the 300 linear foot limit,
continued application of the \1/2\-acre limit, plus the ability of
division and district engineers to exercise their discretionary
authority to modify, suspend, or revoke NWP authorizations on a
regional or case-by-case basis, respectively, will ensure that
activities that would cause more than minimal adverse environmental
effects will be evaluated through the individual permit process.
Many commenters expressed concern about other changes within this
proposal, when combined with the removal of the 300 linear feet limit
would eliminate agency coordination with federal and state resource
agencies under paragraph (d) of general condition 32. One commenter
said that when reviewing the number of individual permits issued versus
activities authorized under NWPs that even with what the commenter
considers the more stringent 300-linear foot limit in place there is no
justifiable need for reducing regulatory burden since the number of
individual permits is so small compared to NWP verifications and this
change would likely not result in any significant decrease in number of
individual permits or regulatory burden.
For the 10 NWPs that had the 300 linear foot limit for losses of
stream bed, the agency coordination process in paragraph (d) of general
condition 32 was limited to requests for waivers of the 300 linear foot
limit for losses of intermittent and ephemeral stream bed. Ephemeral
streams are not waters of the United States (see 33 CFR 328.3(b)(3))
and therefore not subject to jurisdiction under Section 404 of the
Clean Water Act. In its Regulatory Impact Analyses for the proposed and
final rules, the Corps acknowledges that the removal of the 300 linear
foot limit is likely to result in a modest increase in NWP
authorizations (174 per year), and a commensurate decrease in the
number of activities that require individual permits. However, a modest
reduction in the number of individual permits that must be processed
each year can help improve administration of the Corps Regulatory
Program and allow the Corps to devote more time and resources to
working with project proponents to reduce the environmental impacts of
activities that have the potential to result in more substantial
impacts to jurisdictional wetlands and waters.
Many commenters said that the proposed \1/10\-acre mitigation
threshold for losses of stream bed was not an adequate tool for
ensuring no more than minimal adverse environmental effects based on
the disproportionately large amount of impacts to smaller headwater
streams that would need to occur before compensatory mitigation was
required. Many commenters expressed concern about the potential for
increased likelihood for out-of-kind mitigation being provided to
offset headwater stream impacts if mitigation is based on an acreage or
other area-based metric for losses of stream bed. These commenters said
that out-of-kind mitigation would likely increase because it would be
the only option available to permittees due to fewer stream credits
being generated and available as mitigation bankers and other
mitigation providers adapt to this change and the uncertainty in the
market that this change might create.
The comments received on the proposed \1/10\-acre threshold for
stream mitigation are discussed in the section of this preamble that
discusses the comments received on general condition 23. In response to
those comments, the Corps reduced the threshold for stream mitigation
from \1/10\-acre to \3/100\-acre. As explained in the discussion of
general condition 23 below, this change in the stream mitigation
threshold aligns with current practice for stream mitigation
requirements in the NWP program, and the recommendations for the stream
mitigation threshold provided by commenters. The Corps uses a watershed
approach for compensatory mitigation (see 33 CFR 332.3(c)). The goal of
a watershed approach is to maintain and improve the quality and
quantity of aquatic resources within watersheds through strategic
selection of compensatory mitigation sites (see 33 CFR 332.3(c)(1)). A
watershed approach considers how the types and locations of
compensatory mitigation projects will provide the desired aquatic
resource functions, and will continue to function over time in a
changing landscape (33 CFR 332.3(c)(2)(i)), and may involve the use of
out-of-kind mitigation.
Under a watershed approach, other approaches to stream restoration
may be used to generate stream credits besides headwater stream channel
reconfiguration projects. These other approaches may include process-
based
[[Page 2767]]
stream restoration activities such as dam removal, culvert
replacements, levee setbacks or removals, riparian area restoration,
allowing beavers to construct dams to aggrade incised channels, or
installing structures that mimic beaver dams to aggrade incised
channels (Beechie et al. 2010) to generate compensatory mitigation
credits for activities authorized by these NWPs. The use of beaver dams
or structures to aggrade incised stream channels may result in wetland/
stream complexes for which an area-based credit metric may be more
appropriate than a linear foot-based metric. Focusing on restoring
stream functions can be more ecologically successful in improving
stream functions than form-based restoration approaches such as channel
reconfiguration that have had questionable success in restoring
degraded streams (Palmer et al. 2014). The stream credits generated by
channel reconfiguration projects in headwater streams can be quantified
in linear feet or acres, because the Corps' compensatory mitigation
regulations do not mandate a specific approach for quantifying stream
credits. Section 332.8(o)(1) states that the principal units for
credits and debits are acres, linear feet, functional assessment units,
or other suitable metrics of particular resource types. The preamble to
the 2008 mitigation rule states that ``district engineers retain the
discretion to quantify stream impacts and required compensatory
mitigation in terms of area or other appropriate units of measure'' (73
FR 19633).
The Corps received many comments and questions about how these
changes would likely negatively affect long-standing stream mitigation
accounting and the mitigation banking industry in general. These
commenters said that a linear foot metric has always been used for
stream assessment methodologies and the basis for mitigation accounting
systems, and many commenters stated that changing this metric would be
unnecessarily burdensome and costly to stream restoration professionals
and likely result in fewer stream restoration projects. One commenter
stated that the proposed change would not increase mitigation
opportunities in larger or higher order stream channels as proposed
since the restoration of larger streams is more complex than smaller
streams and is dependent on many variables to include funding
availability, site selection, engineering and design considerations,
mitigation requirements associated with the project, market incentives,
and the inability to control future impacts in the headwaters which can
jeopardize the larger stream restoration project.
As stated in the previous paragraphs, the Corps' regulations do not
require use of a linear foot metric for stream assessment methodologies
or for quantifying stream impacts or compensatory mitigation credits.
The removal of the 300 linear foot limit for losses of stream bed and
the changes to general condition 23 are likely to benefit the
mitigation banking industry by providing more opportunities for stream
restoration projects that can generate stream credits to offset losses
of stream bed authorized by the NWPs and other types of DA permits. The
Corps acknowledges that some efforts will need to be made to address
differences in accounting systems, but mitigation providers including
mitigation bank sponsors and in-lieu fee program sponsors should be
able to estimate the amount of stream credits quantified in linear feet
that are needed to offset an specific acreage of stream bed lost as the
result of an NWP activity. The district engineer can assist in these
determinations to ensure that the amount of stream mitigation credits
is roughly proportional to the authorized losses of stream bed.
Several commenters said that establishing a stream compensatory
mitigation threshold of \1/10\-acre would allow approximately 1,675
linear feet of a first order stream channel with a 2.6-foot wide
channel to be impacted under these NWPs before any compensatory
mitigation would be required, which does not meet the Corps' mandated
goal of no net loss to aquatic resources and would cause more than
minimal effects to these aquatic resources.
In response to public comment, the Corps has modified paragraph (d)
of general condition 23 to change the proposed \1/10\-acre threshold
for stream mitigation to \3/100\-acre to make the threshold more
consistent with current practice and the recommendations made by
commenters. The reasons for changing the proposed \1/10\-acre stream
mitigation threshold to \3/100\-acre are provided in the discussion of
general condition 23 below. There is no mandated goal of no net less to
aquatic resources in any law or regulation that applies to the Corps'
NWP Program. Compensatory mitigation, including stream compensatory
mitigation, is required for NWP activities on a case-by-case basis to
ensure that the authorized activities result in no more than minimal
adverse environmental effects. District engineers determine when
compensatory mitigation is required for NWP activities. In prior
versions of the NWPs, the Corps had no threshold for requiring
compensatory mitigation for losses of stream bed, so those commenters
were referring to district practices. Corps districts determined on an
activity-specific basis when stream mitigation is necessary for
specific NWP activities.
One commenter asserted that based on ORM2 data analyzed for stream
channel impacts, that the proposed \1/10\-acre stream compensatory
mitigation threshold would result in the loss of an additional 130,000
linear feet of headwater streams in which no mitigation would be
provided. Several commenters expressed concerns about how this change
would affect current mitigation banks that were in the process of being
approved and inquired whether all previously executed mitigation
banking instruments would need modification to continue to operate and
sell credits to permittees. One commenter said that the proper
regulatory tool to rectify the disparity between stream impacts versus
stream mitigation would be the 2008 mitigation rule and requiring
higher mitigation ratios and not revision of these NWPs.
The 2017 NWPs and prior NWPs had no threshold for requiring stream
mitigation for NWP activities. The proposed addition of the \1/10\-acre
stream mitigation threshold in paragraph (d) of general condition 23 is
a new threshold. That threshold has been reduced to \3/100\-acre in
response to many commenters that provided calculations to support the
reduction. Many commenters did not take into account the ability of
district engineers to require stream compensatory mitigation for losses
of stream bed less than the acreage threshold specified in paragraph
(d) of general condition 23. This is similar in practice to the \1/10\-
acre wetland mitigation threshold in paragraph (c) of general condition
23, where district engineers also have had the authority to require
wetland compensatory mitigation for wetland losses less than \1/10\-
acre.
Several commenters recommended delaying these changes to allow for
more time to study potential effects and one commenter requested that
due to the potential for significant environmental effects, an
environmental impact statement should be prepared for this propose
change. One commenter said that the Corps already converts stream loss/
impacts to acreage in their Regulatory Program database (ORM2) for
accounting purposes and asked would the change from linear feet to
acreage even be needed in the first place. Several commenters said that
the current 300-linear foot threshold was
[[Page 2768]]
too high and should be even further reduced.
The Corps is only removing a quantitative limit from these 10 NWPs,
and is not changing stream compensatory mitigation requirements aside
from establishing an acreage threshold in paragraph (d) of general
condition 23 that is generally consistent with current agency practice.
Under the waiver provision in the 2017 version of these 10 NWPs,
district engineers could waive the 300 linear foot limit for losses of
intermittent and ephemeral stream beds, but the loss of stream bed
could not exceed \1/2\-acre. Therefore, it has been a long-standing
practice in the NWP program to quantify of losses of stream bed in
acres. The removal of the 300 linear foot limit and the change to
general condition 23 does not require an environmental impact
statement. As one commenter recognized, the Corps tracks losses of
stream bed in its ORM2 database in acres.
Several commenters seemed to misunderstand the PCN requirements of
these NWPs and believed that the proposed changes implied that no
notification would be required for any losses of waters of the United
States less than \1/10\-acre for any of these NWPs and that the \1/10\-
acre mitigation threshold was the same as the PCN threshold. This
misunderstanding resulted in many comments concerned about the Corps
not even knowing what impacts are occurring if PCN thresholds are not
triggering activity-specific review of these activities by district
engineers, and stated that this change would allow activities with more
than minimal adverse environmental effects to occur. Several commenters
said that the rulemaking process for the NWPs in cases where the Corps
does not review PCNs the authorization is automatically issued in some
cases with no mitigation proposed. These commenters stated that not
requiring PCNs could cause more than minimal impacts.
The \1/10\-acre stream mitigation threshold proposed in paragraph
(d) of general condition 23 is not the same as the \1/10\-acre PCN
threshold in NWP 51. If activities are authorized by NWPs without the
requirement to submit PCNs, then compensatory mitigation is not
required for those NWP activities, because compensatory mitigation
requirements must be imposed by district engineers by adding conditions
to the NWP authorization. However, it should be noted that all
activities authorized by these 10 NWPs require PCNs, except for certain
activities authorized by NWPs 43 and 51. Nationwide permit 43 does not
require PCNs for the maintenance of stormwater management facilities.
Nationwide permit 51 does not require PCNs for the loss of \1/10\-acre
or less of waters of the United States.
Many commenters said that the removal of the 300 linear foot limit
would result in a loss of critical habitat for many aquatic species
listed under the Endangered Species Act which have cultural and
economic importance to tribes. One commenter stated that the removal of
the 300 linear foot limit could result in long reaches of streams
channels upstream of tribal lands being developed which could cause,
without any notification to the affected tribes, downstream changes to
tribal lands in terms of stream flow, water quality, subsistence of
water use, or cultural water use. Several commenters asked how the
tools that the Corps mentioned in the proposed rule as safeguards, such
as the PCN review process, regional conditions, activity-specific
permit conditions, and use of discretionary authority, prevent more
than minimal adverse environmental effects. Several commenters oppose
the proposed removal of the 300 linear foot limit because it could
essentially be a `tipping point' for a headwater stream system, and
that there would be no way to recover the functions and values lost to
that system because of approval of large impacts to streams.
The removal of the 300 linear foot limit does not affect how
compliance with Section 7 of the ESA is conducted for the NWPs. If the
district engineer reviews a PCN for a proposed activity authorized by
NWPs 21, 29, 39, 40, 42, 43, 44, 50, 51, or 52, and determines that
activity may affect listed species or designated critical habitat, she
or he will conduct section 7 consultation with the U.S. FWS or NMFS as
appropriate. Activities authorized by these NWPs must also comply with
general condition 17, tribal rights. During the rulemaking process for
these NWPs, Corps districts have been consulting or coordinating with
tribes to identify regional conditions and coordination procedures to
help ensure compliance with general condition 17. As discussed in the
proposed rule, the PCN review process, regional conditions, and
activity-specific conditions have been used successfully for years to
ensure that activities authorized by the NWPs result in no more than
minimal adverse environmental effects. Tipping points are difficult to
identify, and if they can be identified, they are likely to vary from
watershed to watershed.
One commenter said that headwater streams warrant more protection
because of their relative importance in providing habitat, hydrologic,
and water quality benefits to downstream waters, and said that
replacing a linear metric with an area-based metric will reduce
protection of headwater streams. This commenter stated that most
nutrient and hydrologic inputs to streams occur along the borders of
riparian zones and streams, so impacts to streams should be quantified
in linear feet. In addition, this commenter noted that the longer total
stream length and higher nitrogen removal efficiency of lower order
streams is the main reason stream length is so important to water
quality and why headwater streams are much more important to water
quality functions in stream networks than are higher order streams.
This commenter said that headwater streams are being lost at high
rates, and that more losses of these streams will result in increases
of eutrophication of downstream waters, more downstream flooding, and
more transportation of pollutants to downstream waters. This commenter
stated that using area as a quantitative limit for both headwater
streams and higher order rivers will decrease protection and diminish
the ecological importance of headwater streams. This commenter
concluded that the current linear foot limit is appropriate for streams
because they are linear systems that interact with their landscapes
along linear borders.
The Corps believes that an appropriate level of protection can be
provided to headwater streams through the \1/2\-acre limit, the PCN
process, and the ability of division and district engineers to modify,
suspend, or revoke NWP authorizations on a regional or case-by-case
basis, respectively. When reviewing PCNs, district engineers will apply
the 10 criteria identified in paragraph 2 of Section D, District
Engineer's Decision. In regions where there are concerns that the use
of the NWPs may result in more than minimal cumulative adverse effects
to headwater streams and the functions they provide, division engineers
can add regional conditions to these NWPs to establish an acreage limit
lower than \1/2\-acre or revoke one or more of these NWPs. Headwater
streams are not provided any special status under the Corps'
regulations or the U.S. EPA's Clean Water Act Section 404(b)(1)
Guidelines. The only streams that are special aquatic sites under the
404(b)(1) Guidelines are riffle and pool complexes (see 40 CFR 230.45),
and many headwater streams are not riffle and pool complexes.
For the reasons provided above, the Corps has removed the 300
linear foot limit from NWPs 21, 29, 39, 40, 42, 43, 44, 50, 51, and 52.

G. Response to Comments on Specific Nationwide Permits
(1) NWP 12. Oil or Natural Gas Pipeline Activities
The Corps proposed to modify this NWP to limit it to oil or natural
gas pipeline activities, and issue two new NWPs to authorize electric
utility line and telecommunications activities (proposed new NWP C, now
designated as NWP 57) and utility line activities for water and other
substances (proposed new NWP D, now designated as NWP 58). The Corps
also invited public comment on national construction standards and best
management practices that could be incorporated into the text of NWP 12
to help ensure that this NWP authorizes only those activities (i.e.,
discharges of dredged or fill material into waters of the United States
and/or structures or work in navigable waters of the United States)
that result in no more than minimal individual and cumulative adverse
environmental effects.
General Comments
Some commenters expressed their support for dividing NWP 12 into
three separate NWPs while some commenters objected to that aspect of
the proposed rule. Many commenters stated that the Corps should reissue
NWP 12 in its current form. One commenter said that the 2017 NWP 12
contains sufficient PCN thresholds and conditions to provide
appropriate environmental protections. One commenter objected to the
proposed modifications to NWP 12 made in response to E.O. 13783,
Promoting Energy Independence and Economic Growth, stating that these
changes would make it easier for oil and gas pipeline activities to
occur at the expense of the environment. Several commenters said that
the Corps should limit the number of activities authorized by this NWP
because continuing to authorize these activities contributes to
cumulative effects to natural resources.
After reviewing the comments received in response to proposed NWPs
12, C, and D, the Corps is finalizing and issuing these NWPs.
Nationwide permit 12 authorizes oil or natural gas pipeline activities,
NWP 57 authorizes electric utility line and telecommunications
activities, and NWP 58 authorizes utility line activities for water and
other substances. These NWPs are issued to fulfill the objective of the
NWP program, which is to authorize, with little, if any, delay or
paperwork certain activities having no more than minimal impacts (33
CFR 330.1(b)). The proposed modifications to NWP 12 were made, in part,
to respond to the direction provided by E.O. 13738, which is to revise
existing regulations that ``unduly burden the development of domestic
energy resources beyond the degree necessary to protect the public
interest or otherwise comply with the law.'' In this NWP, the Corps has
retained the terms and conditions that are necessary to ensure that the
activities authorized by this NWP result in no more than minimal
individual and cumulative adverse environmental effects. The Corps
acknowledges that the use of the NWPs to authorize activities during
the 5-year period the NWP is in effect results in some cumulative
adverse environmental effects, but the limits, PCN requirements,
general conditions, and the ability of division and district engineers
to modify, suspend, and revoke NWP authorizations all help to ensure
that this NWP causes no more than minimal cumulative adverse
environmental effects at the national, regional, and site scales.
A few commenters stated that the proposed NWP 12 would result in
reduced opportunities for the Corps and for the public to evaluate the
impacts of oil and natural gas pipeline activities on water resources
and the environment in general. One of these commenters said that the
Corps should provide additional opportunities for public involvement.
One commenter stated that public participation opportunities during the
NWP permitting process are sufficient; and expanding the existing
requirements at the district level would cause unwarranted delays in
permitting. One commenter suggested that the Corps should notify the
public of proposed NWP 12 activities. A few commenters said that
pipelines can cause significant direct and indirect impacts to fish and
wildlife habitat and water quality associated with an increase in
watershed runoff.
The public is provided an opportunity to comment on the Corps'
proposal to issue, reissue, or modify an NWP when Corps Headquarters
publishes its proposed rule in the Federal Register to start the public
comment period. However, after an NWP is issued, there is no public
comment process for specific NWP activities. If, for a proposed oil or
natural gas pipeline activity, the district engineer exercises
discretionary authority and requires an individual permit for that
activity, the public will have an opportunity to provide comments in
response to the public notice issued by the Corps district. When
reviewing PCNs for proposed oil or natural gas pipeline activities,
district engineers consider the potential direct and indirect impacts
on fish and wildlife habitat and water quality, as well as other public
interest review factors identified in 33 CFR 320.4(a)(1).
One commenter said that natural gas pipeline activities authorized
by NWP 12 comply with industry standards that are protective of the
environment and public safety. One commenter stated that pipelines
provide a safe, reliable, efficient, and cost-effective way to move
bulk liquids, particularly over long distances, and that the U.S.
Department of Transportation's Pipeline and Hazardous Materials Safety
Administration concurs with that statement. The Corps acknowledges
these comments.
One commenter said that while oil or natural gas pipelines may be
regulated by other agencies, the Corps is not relieved of its
obligation to conduct a NEPA analysis for leaks or spills. A few
commenters stated that the Corps must consider in its NEPA review the
impacts that could result from authorizing a pipeline that would carry
toxic material, including leaks or spills, and that the draft decision
document doesn't take the required ``hard look''.
In the national decision document for the issuance of this NWP, the
Corps discusses leaks or spills that may occur during the construction
and/or operation of oil or natural gas pipelines. The Corps does not
have the authority to take actions to prevent or control potential
leaks or spills that may occur during the construction or operation of
oil or natural gas pipelines. Since the Corps does not regulate the
release of oil, natural gas, or products derived from oil or natural
gas, it is not required to perform a detailed analysis of the effects
of those possible future leaks or spills because those leaks or spills
are not an effect of the Corps' proposed action (see the definition of
``effects or impacts'' at 40 CFR 1508.1(g)).
One commenter stated that pipeline abandonment issues in NWP 12
should be treated consistently across the districts and recommended
that the NWP 12 terms should provide this consistency. A few commenters
said that NWP 12 should continue to authorize emergency installation,
replacement or repair of utility lines. One commenter requested that
the Corps clarify the types of time-sensitive activities, including
integrity digs, that are authorized under NWPs 12 and 3. One commenter
requested clarification of the scope of maintenance activities under
NWP 12. One commenter said that the Corps should facilitate the
construction, repair, and/or replacement of climate resilient
underground linear infrastructure to support climate
[[Page 2770]]
adaptive and resilient energy systems through the issuance of general
permits.
Corps districts have discretion to determine on a case-by-case
basis how to address pipeline abandonment activities. Nationwide permit
12 can be used to authorize emergency installation, replacement or
repair of utility lines. The reduction of the number of PCN thresholds
for this NWP may facilitate the implementation of these emergency
activities by reducing delays in securing NWP authorization. The Corps
does not believe that it is necessary add text to the NWP to
specifically address integrity digs, because discharges of dredged or
fill material into waters of the United States for integrity digs can
be considered part of maintenance, which is included in the first
sentence of this NWP. The activities authorized by this NWP can
contribute to the construction, repair, and/or replacement of climate
resilient underground linear infrastructure to support climate adaptive
and resilient energy systems.
One commenter stated that the Corps should ensure that activities
authorized by NWP 12 do not commence construction in uplands in
protected critical habitats until the ESA section 7 consultation
process has been completed. A few commenters indicated concern that
cumulative impacts are not adequately considered in the decision
document for NWP 12. A few commenters asserted that the scope of the
cumulative impacts has proven to be more than minimal. One of these
commenters stated that the draft decision document for NWP 12 already
acknowledges that the cumulative impacts are more than minimal. A few
commenters said that the Corps should consider the cumulative upstream
and downstream impacts of its actions regarding oil and natural gas
pipelines, including climate impacts. A few commenters expressed
concern for potential effects on drinking water and aquifers. One
commenter expressed a general concern for waterways affected by NWP 12
activities.
The Corps does not have the authority to prevent project proponents
from conducting activities in uplands before they receive NWP
verifications from district engineers in response to PCNs. The national
decision documents issued by Corps Headquarters address cumulative
impacts in accordance with the Clean Water Act Section 404(b)(1)
Guidelines at 40 CFR 230.7 for the issuance of general permits. The
Council on Environmental Quality's NEPA regulation at 40 CFR
1508.1(g)(3) repealed the 1978 definition of ``cumulative impact,'' so
under the current NEPA regulations the cumulative effects analysis for
an NWP is similar to the approach the Corps uses under 40 CFR
230.7(b)(3): Estimating the number of times the NWP is anticipated to
be used during the 5-year period it will be in effect, the authorized
impacts to jurisdictional waters and wetlands, and the compensatory
mitigation required to offset losses of jurisdictional waters and
wetlands. Those impacts, and the compensatory mitigation, are evaluated
against the current environmental setting (i.e., the affected
environment), which includes the past and present effects of human
activities and natural events that have shaped the current
environmental setting. The Corps does not have the authority to
regulate the operation of any oil or natural gas pipeline, or the
emissions that result from combustion of oil or natural gas, or from
the industrial processes that derive other products from oil or natural
gas. Therefore, under the current NEPA regulations, the Corps is not
required to evaluate those upstream and downstream impacts, including
potential impacts on the planet's climate. The national decision
document for this NWP considers effects on water supply and
conservation as part of the public interest review. When reviewing
PCNs, district engineers will evaluate the effects of proposed NWP
activities on waterways.
Activities Authorized by NWP 12
One commenter said that the first sentence of NWP 12 should be
revised as follows: ``Activities required for the construction,
replacement, maintenance, repair and removal of oil, natural gas and
gaseous fuel pipelines and utility lines and associated facilities in
waters of the United States, provided the activity does not result in
the loss of greater than \1/2\-acre of waters of the United States for
each single and complete project.'' The Corps declines to make this
change because it is covered by the definition of ``oil or natural gas
pipeline'' provided in the second paragraph of this NWP.
Oil or natural gas pipelines. One commenter stated that if the
Corps moves forward with limiting NWP 12 to oil or natural gas pipeline
activities, it should also delete the phrase ``including outfall and
intake structures'' because oil and natural gas pipelines and
distribution systems do not contain water outfall or water intake pipe
structures. The Corps has made this change to the second paragraph of
this NWP.
A few commenters said that the terms ``oil'', ``gas'', and
``natural gas'', and ``petrochemicals'' are vague and overbroad for the
purposes of determining compliance with the proposed NWPs and can have
various meanings, and that any proposed changes should be subjected to
notice and comment procedures. A few commenters stated that terms
associated with the proposed NWP 12 that require clarification include
``utility lines,'' since pipeline activities authorized by NWP 12 might
be both pipelines and utility lines; ``other substances,'' because gas
and petrochemicals can be found in many types of infrastructure and
industrial products; and ``gas'' and ``natural gas,'' because liquified
petroleum gas is not a natural gas.
The Corps has made changes to the definition of ``oil or natural
gas pipeline'' to take into account the wide variety of products that
may be derived from oil or natural gas and transported in these
pipelines. In response to comments received in response to the 2020
Proposal, and to provide additional clarity on the types of products
that may be transported by oil or natural gas pipelines versus utility
line activities that may be authorized by NWP 58, the Corps has
replaced the term ``petrochemical products'' with the phrase ``products
derived from oil or natural gas, such as gasoline, jet fuel, diesel
fuel. heating oil, petrochemical feedstocks, waxes, lubricating oils,
and asphalt.'' The revised definition was developed using information
from the U.S. Energy Administration.\2\
---------------------------------------------------------------------------
\2\ https://www.eia.gov/energyexplained/oil-and-petroleum-products/ (accessed November 4, 2020).
---------------------------------------------------------------------------
A few commenters said that the proposed definition of ``oil or
natural gas pipeline'' for the proposed NWP 12 is inadequate and
inconsistent with the definitions in the Oil Pollution Act. One
commenter suggested the Corps add ``and derivatives'' after
`petrochemical products' for clarity. One commenter suggested removal
of the phrase ``for any purpose'' from the proposed definition of ``oil
or natural gas pipeline'' because it creates uncertainty about what
activities may actually be authorized by the NWP.
The Corps developed its own definition because this NWP also
authorizes regulated activities associated with natural gas pipelines
and products derived from oil or natural gas. The Corps has deleted
``for any purpose'' because NWP 12 is now limited to oil or natural gas
pipeline activities.
One commenter stated that the existing NWP 12 uses the category
[[Page 2771]]
``utility lines'' which is still used in proposed NWPs C and D, but the
proposed NWP 12 uses the new term ``oil and natural gas pipelines''
which causes conflicting redundancies with various aspects of the
proposed NWPs 12, C, and D. One commenter said that many of natural gas
pipe construction and repair projects that will need NWP authorization
involve pipelines that will be used to transport geologic natural gas
as well as other lower carbon gaseous fuels such as renewable natural
gas, hydrogen, and power-to-gas methanated hydrogen. This commenter
said that to avoid confusion and streamline the process for these
projects, the Corps should not split off any buried pipe-based utility
lines into the proposed new NWP D. One commenter remarked that the
Corps should clarify that NWP 12 is available for underground pipelines
and utility lines whether they carry geologic natural gas or a blend
with lower-carbon gaseous fuels.
Nationwide permits 12, 57, 58 authorize activities for different
types of utility lines, so there will be some redundancies because of
similarities among these different types of utility lines, but there
are also some differences, which result in different text in each of
these NWPs. Nationwide permit 12 authorizes oil or natural gas pipeline
activities that may carry different types of natural gas. Nationwide
permit 58 can be used to authorize pipeline activities that require DA
authorization and are used to convey hydrogen, methanated hydrogen, or
carbon dioxide.
Oil or natural gas pipeline substations. One commenter said that
the paragraph on substations in the proposed NWP 12 should be revised
to state that it authorizes construction, maintenance, replacement or
expansion work in a non-tidal jurisdictional water for an oil or
natural gas or gaseous fuel custody transfer station, boosting station,
compression station or metering and/or pressure regulating station. One
commenter said that if the Corps issues proposed new NWP C, then the
references to ``substations'' should be removed from NWP 12 and
replaced with boosting or compressor stations and natural gas metering
and pressure regulating station. This commenter also recommended
revising the fourth paragraph in the proposed NWP 12 to state that it
authorizes construction, maintenance, replacement or expansion work in
a non-tidal jurisdictional water for an oil or natural gas or gaseous
fuel custody transfer station, boosting station, compression station or
metering and/or pressure regulating station. One commenter noted that
the term ``natural gas pipeline substation'' is used in the proposed
language for the proposed NWP 12 and requested clarification regarding
how above-ground natural gas facilities including district regulators
and gate stations fit into NWP 12.
The Corps has modified this paragraph to provide examples of
substations associated with oil or natural gas pipelines. This NWP can
be used to authorize discharges of dredged or fill material into waters
of the United States for above-ground natural gas facilities including
district regulators and gate stations.
Access roads. One commenter said that only temporary access roads
should be authorized by NWP 12, and that permanent access roads are
more appropriately authorized under NWP 14. The Corps disagrees, and is
retaining the NWP authorization for permanent access roads, because
access roads are associated with utility lines are not usually
available for public use.
One commenter said that the proposal to add the word ``over'' to
activities that are routed in or under navigable waters subject to
Section 10 of the Rivers and Harbors Act of 1899 is unnecessary as
structures routed over section 10 waters would be considered bridges
and be regulated under Section 9 of the Rivers and Harbors Act of 1899.
The Corps has modified the second sentence of the seventh paragraph of
this NWP by adding the word ``may'' because there may be circumstances
where section 10 authorization is required for oil or natural gas
pipelines routed over navigable waters of the United States.
A few commenters stated that the Corps does not have jurisdiction
over inadvertent returns, leaks, or spills. One commenter said that NWP
12 should continue to authorize the remediation of inadvertent returns
of fluids during drilling operations without additional changes. A few
commenters stated that the Corps has not sufficiently evaluated the
risks, impacts, and mitigation measures associated with inadvertent
returns of drilling fluid. A few commenters expressed appreciation for
the clarification in the decision document that the Corps' jurisdiction
is limited to authorizing temporary structures, fills, and work
necessary for the remediation of inadvertent returns of drilling fluids
through sub-soil fissures or fractures that might occur during
horizontal directional drilling.
The Corps does not have jurisdiction over inadvertent returns,
leaks, or spills that may occur during horizontal directional drilling
to install or replace oil or natural gas pipelines. The eighth
paragraph of this NWP authorizes, to the extent that DA authorization
is required, temporary structures, fills, and work necessary for the
remediation of inadvertent returns of drilling fluids to waters of the
United States through sub-soil fissures or fractures that might occur
during horizontal directional drilling activities conducted for the
purpose of installing or replacing oil or natural gas pipelines. The
purpose of this paragraph is to provide authorization for regulated
activities that are necessary to remediate inadvertent returns of
drilling fluids to reduce adverse environmental effects that might be
caused by releases of drilling fluids to the surrounding environment.
One commenter expressed support for retaining the clarification
that NWP 12 authorizes temporary mats for moving equipment. A few
commenters said that the Corps should stop considering temporary mats/
panels as a regulated activity or clarify that they are not to be
considered as a ``loss of waters'' for the purposes of PCN requirements
because of their temporary effects. One commenter requested
clarification that activities resulting in the loss of greater than \1/
10\-acre of waters of the United States require a PCN to the Corps, but
temporary discharges do not count toward that \1/10\-acre PCN
threshold.
The determination as to whether the use of timber mats in waters of
the United States for oil or natural gas pipeline activities
constitutes a discharge of dredged or fill material into waters of the
United States should be made by district engineers after evaluating
site-specific and activity-specific circumstances. Any discharge of
dredged or fill material into waters of the United States that results
in a loss of greater than \1/10\-acre of waters of the United States
requires pre-construction notification. As explained in the definition
of ``loss of waters of the United States,'' waters of the United States
temporarily filled, flooded, excavated, or drained, but restored pre-
construction contours and elevations after construction, are not
included in the measurement of loss of waters of the United States.
One commenter said there is inconsistency in the text of NWP 12
because it states that there must be no change in pre-construction
contours of waters of the United States, but NWP 12 also authorizes
losses of waters of the United States. This commenter recommended
revising the text of NWP 12 to state that ``there must be no change in
pre-construction contours which results in permanent loss of waters of
the United States.'' One commenter stated that the Corps should adopt a
strict interpretation of the
[[Page 2772]]
amount of ``temporary fill'' authorized by this NWP for the purposes of
assessing cumulative impacts and should also consider the timing and
duration of temporary fills, including temporary mats. This commenter
indicated that permitted temporary fills generally occur in stages and
not all at the same time.
Some activities authorized by NWP 12 (e.g., the construction of
substations and permanent access roads) result in permanent fills while
other authorized activities, such as the placement of temporary fills,
require restoration to pre-construction elevations. Temporary fills do
not contribute to cumulative impacts because they are removed upon
completion of the work and the permittee is required to restore the
affected area to pre-construction elevations. The Corps acknowledges
that temporary fills may occur during different stages of construction,
maintenance, repair, or removal of an oil or natural gas pipeline
activity.
Pre-Construction Notification Thresholds
Many commenters opposed reducing the number of PCN thresholds in
this NWP. Several commenters suggested that reducing the PCN
requirement would result in the NWP authorizing activities that have
more than minimal adverse environmental effects, including cumulative
effects. Many of these commenters suggested retaining the existing PCN
thresholds. One of these commenters requested further clarification
regarding which activities would no longer require PCNs. A few of these
commenters stated that maintaining the status quo creates greater
regulatory certainty to the industry. Many commenters said that
reducing the PCN thresholds for this NWP undermines the Corps' ability
to ensure that authorized activities NWPs will result in no more than
minimal individual and cumulative adverse environmental effects, and
reduces the opportunity for the Corps to require individual permits
when adverse environmental effects would be more than minimal. One
commenter remarked that the proposed reduction in PCN thresholds would
cause increased harm to rivers, streams, and wetlands.
The Corps proposed to retain those PCN thresholds associated with
NWP 12 activities that result in losses of waters of the United States
or have potential effects on navigation. To reduce regulatory burdens
in response to E.O. 13783, the Corps proposed to remove a number of PCN
thresholds because of the requirement in the NWP to restore temporary
impacts to pre-construction elevations or because they are already
addressed by another PCN threshold. If a proposed NWP 12 activity does
not trigger any of the three PCN thresholds in the text of the NWP, or
a PCN threshold in the text of one of the NWP general conditions (e.g.,
general condition 18, endangered species and general condition 20,
historic properties), then pre-construction notification is not
required for the proposed activity unless a division engineer has
imposed a regional condition to require PCNs in a particular geographic
region. Division engineers can add regional conditions to add PCN
thresholds that were removed from the text of NWP 12, if he or she
determines the PCN threshold is necessary to ensure that the NWP
authorizes only those activities that have no more than minimal adverse
environmental effects. Adverse effects to rivers, streams, and wetlands
are generally caused by the discharges of dredged or fill material or
structures or work authorized by this NWP, not by the presence or
absence of a PCN threshold.
Many commenters expressed support for proposed reduction in PCN
thresholds for NWP 12 and the associated reduced administrative burden
that reduction would provide. One commenter voiced support for the
reduction in PCN requirements as it would reduce the potential for
infrastructure litigation and encourage private investment. One
commenter stated that PCN thresholds should be removed when they are
duplicative or burdensome. One commenter said that if the PCN
requirements to be removed are truly redundant it would pose no
additional burden on the regulated public.
The Corps acknowledges these comments, and the Corps' intent with
these changes is to reduce burdens on the regulated public and focus
the PCN thresholds on those activities that have some potential to
cause more than minimal adverse environmental effects. For these
activities, district engineers should be given the opportunity to
evaluate these activities on a case-by-case basis.
Many commenters stated that the PCN process incentivizes permittees
to avoid, minimize, and compensate for impacts to aquatic resources in
order to reduce permitting delays. Some of these commenters said that
the reduced PCN requirements would result in violations to general
condition 23, mitigation. One commenter stated that the remaining PCN
thresholds and the other NWP 12 terms and conditions reasonably limit
the adverse environmental effects of the activities authorized by NWP
12. One commenter said that the Corps should encourage the districts to
refrain from adding PCN thresholds to this NWP, specifically through
regional conditions. A few commenters expressed concern that the
reduction of PCN thresholds will likely be subject to litigation. One
commenter suggested that any resulting litigation could cause
uncertainties for the industries that rely on the NWP program.
The NWPs provide incentives for project proponents to reduce
impacts to waters of the United States to obtain DA authorization in
less time than is required under the individual permit process.
Reducing the number of PCNs does not violate general condition 23. The
NWPs authorize activities that have no more than minimal individual and
cumulative adverse environmental effects, and it is not necessary to
require compensatory mitigation for every NWP activity. The PCN
thresholds themselves do not limit adverse environmental effects; the
adverse environmental effects caused by regulated activities authorized
by an NWP are limited by the constraints in the text of the NWP (e.g.,
the \1/2\-acre limit, requirements to restore temporary impacts to pre-
construction elevations) and in the NWP general conditions. Division
engineers have the authority to add regional conditions to replace the
PCN thresholds that were in prior versions of NWP 12, if those division
engineers determine that adding those PCN thresholds is necessary to
ensure that the NWP only authorizes those activities that result in no
more than minimal individual and cumulative adverse environmental
effects. While potential litigation risk is a consideration when
contemplating changes, other factors such as administrative efficiency,
reduction of regulatory burdens, and other approaches for maintaining
environmental protections are other considerations that the Corps
considers as well.
A few commenters stated that the proposed reduction in PCN
thresholds could expedite permit processing time and preclude a
thorough review by the Corps. One commenter said that reducing the
number of PCN thresholds would allow for the potential for spills near
stream beds. One commenter opposed the simplified PCN requirements,
stating that the proposal does not improve inter-agency coordination or
reduce impacts on the environment. One commenter said that PCNs should
be required for all NWP 12 activities. One commenter stated that the
Corps fails to show how compliance with Clean Water Act Section 404(e)
[[Page 2773]]
would be achieved without a process to track all NWP activities.
The reduction in PCN thresholds allows Corps districts to shift
their resources towards evaluating proposed activities that require DA
authorization that have the potential for greater adverse environmental
effects. Reducing the number of PCN thresholds will not alter the
potential for spills to occur near stream beds because spills are
accidents and not planned activities that the Corps would evaluate as
part of a PCN. The reduction in the number of PCN thresholds in NWP 12
does not alter any agency coordination procedures because agency
coordination is not required for any NWP 12 activities. It is not
necessary to require PCNs for all NWP 12 activities, because many of
the activities authorized by NWP 12 result in only temporary impacts to
aquatic resources. The Corps does not have to track all NWP activities
to comply with Section 404(e) of the Clean Water Act. Since the
inception of the NWP program in 1977, many of the NWPs have not require
pre-construction notification, thus the changes that are being
finalized are not a departure from the Corps practice or procedures.
A few commenters said that reducing the PCN requirement does not
comply with the Corps' mandate under ESA section 7 to ensure
consultation occurs when necessary. One commenter said that PCN should
be required for all maintenance activities in waters of the United
States, especially if the waters contain ESA-listed species. A few
commenters opposed reducing the number of PCN thresholds for NWP 12
because the PCN process allows state natural resource agencies to
provide expertise in determining the effect of projects on state
resources, affected species, and their habitat. A few commenters stated
the reduced number of PCN thresholds would not comply with the NHPA.
One commenter said that the proposed reduction in PCN thresholds could
have potential impacts to cultural resources and affect the protection
of historic properties. Several commenters said that the proposed
reduction of PCN thresholds poses risks of significant impacts to
tribal rights and treaty-reserved resources.
General condition 18 addresses compliance with section 7 of the
ESA. Under paragraph (c) of general condition 18, non-federal
permittees must submit a pre-construction notification to the district
engineer if any listed species or designated critical habitat might be
affected or is in the vicinity of the activity, or if the activity is
located in designated critical habitat even if a PCN is not otherwise
required. This includes maintenance activities that might affect listed
species or designated critical habitat. None of the activities
authorized by NWP 12 require coordination with state natural resource
agencies, and the PCN thresholds that have been removed from NWP 12 did
not require that coordination.
General condition 20 addresses compliance with section 106 of the
NHPA. Under paragraph (c) of general condition 20, non-federal
permittees must submit a pre-construction notification to the district
engineer if the NWP activity might have the potential to cause effects
to any historic properties listed on, determined to be eligible for
listing on, or potentially eligible for listing on the National
Register of Historic Places, including previously unidentified
properties even if a PCN is not otherwise required. The reduction in
PCN thresholds for NWP 12 does not change the PCN requirement in
general condition 20. During the process for issuing these NWPs, Corps
districts have been consulting or coordinating with tribes to identify
regional conditions or coordination procedures to ensure that
activities authorized by NWP 12 and other NWPs do not have substantial
adverse effects on tribal rights and, as appropriate, treaty reserved
resources. Division engineers can add PCN requirements to address
tribal concerns as appropriate.
One commenter objected to the lack of a PCN threshold based on
pipeline diameter. One commenter requested that the Corps provide
additional information regarding the outcomes of PCN reviews under the
current NWPs and an explanation for how environmental protection would
be maintained without the PCN review process. One commenter stated that
the Corps should clearly identify the information required by all
applicants to support the analysis of temporal and cumulative impacts
and recommended separate analyses for all impacts to waters of the
United States within the total impact limitation of \1/2\-acre.
Pre-construction notification thresholds are established for
activities that have the potential to result in more than minimal
adverse environmental effects, and pipeline diameter has not been
demonstrated to have potential to be a useful PCN threshold. During
their reviews of PCNs, district engineers document their conclusions as
to whether the proposed activity will result in no more than minimal
adverse environmental effects, or whether it is necessary to exercise
discretionary authority and require an individual permit for the
proposed activity. This documentation includes the district engineer's
consideration of cumulative effects.
In the paragraphs below, the Corps discusses each of the five PCN
thresholds it proposed to remove to simplify the PCN requirements for
this NWP. The Corps discusses the comments received and provides
responses to those comments. In the paragraphs that follow, the Corps
uses the term ``utility line'' because it proposed the same PCN
thresholds for NWP 12 and proposed new NWPs C and D (now designated as
NWPs 57 and 58, respectively in this final rule). Also discussed below
is the Corps' proposal to add a new PCN threshold to NWP 12 for new oil
or natural gas pipelines greater than 250 miles in length.
(i) The activity involves mechanized land clearing in a forested
wetland for the utility line right-of-way. Many commenters said that
allowing mechanized land clearing through forested wetlands without
requiring PCNs will cause more than minimal adverse environmental
effects and recommended that this PCN threshold requirement be
retained. Many commenters said that PCNs should be required for
mechanized land clearing associated with NWP 12 to prevent the loss of
wetland resources, functions and services, including water quality,
erosion control, and flood mitigation. A few commenters suggested a
maximum acreage for forest clearing activities without a PCN associated
with NWP 12. One commenter stated that the PCN threshold should be
modified to require PCNs for ``loss or permanent conversion.''
If construction of an oil or natural gas pipeline involves
mechanized land clearing in a forested wetland for the right-of-way for
that pipeline, the installation of the pipeline must cause no change in
pre-construction contours of waters of the United States. Any temporary
fills must be removed upon completion of construction, and the affected
areas restored to pre-construction elevations. If there are any
permanent fills associated with the mechanized land clearing of a
forested wetland, and the loss of waters of the United States is
greater than \1/10\ acre, a PCN is required. In areas where temporary
fills occur, the wetlands in the right-of-way will remain, although
there may be a conversion in wetland type. Those wetlands will continue
to perform wetland functions, including hydrologic functions,
biogeochemical cycling, and habitat functions, but there may be some
changes to those functions and the degree to which the wetlands perform
those functions. Division
[[Page 2774]]
engineers can impose regional conditions to require PCNs for mechanized
land-clearing in a forested wetland, and they can add regional
conditions to impose an acreage limit on impacts resulting from
mechanized land-clearing of forested wetlands.
Many commenters said that PCNs should be required for mechanized
land clearing in forested wetlands to allow district engineers to
consider avoidance, minimization, and the need for compensatory
mitigation, as compliance with the 404(b)(1) guidelines, and further
recommended retention of this PCN threshold. One of these commenters
stated that temporary impacts should also be considered. Many
commenters expressed concern that mechanized land clearing in forested
wetlands would result in the long-term and/or permanent conversion of
these areas to emergent and scrub-shrub wetlands, and further indicated
that these scrub-shrub and emergent wetlands do not provide the same
degree of ecological functions and services or provide the same values.
Several of these commenters asserted that this conversion in wetland
type causes more than minimal adverse effects to the environment.
Paragraph (a) of general condition 23 requires project proponents
to design and construct their NWP activities to avoid and minimize
temporary and permanent adverse effects to waters of the United States
to the maximum extent practicable at the project site (i.e., on site).
Division engineers can add regional conditions to this NWP to require
PCNs and compensatory mitigation for mechanized land-clearing of
forested wetlands. Activities that are authorized by NWPs do not
require activity-specific evaluation under the 404(b)(1) Guidelines
(see 40 CFR 230.5(b)). Emergent and scrub-shrub wetlands perform valued
wetland functions, even though those functions differ to some degree
from the functions performed by forested wetlands.
A few commenters stated that clearing of forested wetlands can
impact wetland hydrology and soils through rutting and soil compaction
by machinery. Many commenters stated that a review of pre- and post-
construction hydrogeomorphic method assessments demonstrates
significant permanent impacts to forested wetlands resulting from
mechanized land clearing and temporary discharges. Several commenters
said that forested wetlands along the Gulf Coast provide vital stopover
areas for migratory birds and that the proposed removal of this PCN
threshold would be most profound along the Gulf Coast where pipelines
are regularly constructed through forested wetlands.
The text of this NWP that applies to the construction of the
pipeline requires that there is no change in pre-construction contours
of waters of the United States. If there are permanent impacts to
certain features of these forested wetlands, those impacts are caused
by the activities authorized by NWP 12, not the presence or absence of
any PCN threshold. Soil compaction can be caused by a variety of
activities other than discharges of dredged or fill material. If the
activity results in a loss of greater than \1/10\-acre of waters of the
United States, then the project proponent is required to submit a PCN.
For those Corps districts in the Gulf Coast, division engineers add
regional conditions to require PCNs for mechanized land-clearing
activities in forested wetlands.
Several commenters said that the Corps does not cite any sources
for stating that mechanized land clearing in forested wetlands usually
results in only temporary impacts. A few commenters stated that the
Corps has not provided any scientific rationale demonstrating that loss
of forested wetland would not result in more than minimal adverse
environmental effects. A few commenters said that the consensus in the
scientific literature contradicts the Corps' assertion, with multiple
studies and practices indicating that mechanized clearing results in
irreversible and permanent alteration of forested wetland's functions.
One commenter cited paragraph (i) of general condition 23 which allows
district engineers to require mitigation for the permanent conversion
of wetland types to offset losses of specific functions. One commenter
said that the functions of forested wetlands have been estimated by the
Corps to have a value of $10,401 per acre per year. A few commenters
stated that mechanized land clearing can result in sediment disturbance
and potential water quality impacts in wetland areas. A few commenters
stated that removing the PCN requirement for mechanized land clearing
in forested wetlands would make NWP 12 vulnerable to litigation.
The text of NWP 12 requires temporary impacts to be restored after
the pipeline is constructed. If the construction of the pipeline
results in the loss of greater than \1/10\-acre of waters of the United
States, then the project proponent is required to submit a PCN to the
Corps. The removal of the PCN threshold is an administrative decision
to improve regulatory efficiency, reduce redundancy, and focus the
district engineer's evaluation efforts on proposed activities that have
the potential to result in more than minimal adverse environmental
effects. If mechanized land-clearing causes irreversible and permanent
alteration of forested wetland's functions, it is because of the
physical effects of the discharge of dredged or fill material into
waters of the United States and the periodic maintenance in the
pipeline right-of-way that causes those changes in wetland functions.
The Corps regulates the former, but does not regulate the mowing and
cutting of vegetation to maintain the plant community in the pipeline
right-of-way as herbaceous vegetation or scrub-shrub vegetation.
Paragraph (i) of general condition 23 is retained in these NWPs, so for
those NWP 12 activities that require PCNs, district engineers can
require compensatory mitigation to offset permanent losses of certain
wetland functions.
One commenter stated that impacts to forested wetlands are
permanent or semi-permanent and should not be considered temporary. One
commenter suggested the cumulative effects of forested wetland
conversion cannot be tracked without a PCN requirement. One commenter
stated that the removal of the PCN for mechanized land clearing in
forested wetlands is a change with implications for market growth of
the ecological restoration industry. One commenter stated that
mechanized land clearing can increase non-point source pollution in a
water of the United States and can increase nutrient loading in first
and second order streams. One commenter said that mechanized land
clearing in forested wetlands is associated with an increase in the
spread of invasive species.
Forested wetlands that have been converted to herbaceous or scrub-
shrub wetlands continue to function as wetlands. Therefore, from a
wetland perspective, the impacts caused by the below-ground
installation of the pipeline are temporary as long as temporary fills
are removed and the affected area is restored to pre-construction
elevations. Although the wetland type has changed as a result of the
activity, district engineers can require compensatory mitigation to
offset losses of specific wetland functions for those NWP 12 activities
that require PCNs. If the permittee wants to conduct mechanized land
clearing of a forested wetland for an oil or natural gas pipeline
right-of-way, he or she must restore the disturbed soils so that there
is no change in pre-construction contours of waters of the United
States in that right-of-way. If there will be permanent changes in pre-
[[Page 2775]]
construction contours in waters of the United States, and the area of
those permanent changes will exceed \1/10\-acre, then a PCN is
required. Permanent adverse effects can be addressed through the PCN
review process. Where appropriate to ensure minimal adverse effects on
the environment in a particular region, division engineers can add
regional conditions to require PCNs for mechanized land clearing in a
forested wetland right-of-way.
(ii) The utility line in waters of the United States, excluding
overhead lines, exceeds 500 feet. One commenter stated that the 500
linear foot PCN threshold should be maintained since the \1/10\-acre
threshold only covers losses of waters of the United States and
retaining it would allow the district engineer to evaluate the site-
specific conditions and make an informed decision. One commenter said
that removal of the 500 linear foot PCN threshold limits the Corps
ability to review projects that will affect habitat, ecosystems, and
the environment on tribal lands and within tribal usual and accustomed
areas that cross state lines and international borders and further
indicated that this would constitute a violation of the United States
and trust and responsibility and obligation to protect treaty
resources.
The \1/10\-acre PCN threshold for losses of waters of the United
States provides an opportunity for district engineers to evaluate site-
specific conditions and determine whether the proposed oil or natural
gas pipeline activities are authorized by NWP 12. The \1/10\-acre PCN
threshold also provides district engineers with the opportunity to
assess potential effects on habitat, ecosystems, environmental
conditions on tribal lands, and tribal usual and accustomed areas.
District engineers can work with tribes to develop coordination
procedures to help protect treaty resources. In addition, activities
authorized by NWP 12 must comply with general condition 17, tribal
rights.
One commenter said that if this PCN threshold is removed, the Corps
cannot evaluate the impacts of temporary losses or determine if
specific restoration or mitigation measures are necessary, or if an
individual permit would be necessary. One commenter said that the
proposal to remove the 500 linear foot PCN threshold should be
coterminous with other section 404 permitting requirements, but since
this justification does not apply in all situations it is
inappropriate. An example cited by this commenter is utility lines
directionally drilled under wetlands.
Temporary impacts should not normally require PCNs because the
aquatic resources and the functions they provide should recover after
the temporary fills are removed and the affected area restored to pre-
construction elevations. The removal of the 500 linear foot PCN
threshold improves the Corps' efficiency in administering the section
404 program. Further, it is consistent with section 404 permitting
requirements, because the Corps determines which activities should
require PCNs to trigger review on a case-by-case basis.
(iii) The utility line is placed within a jurisdictional area
(i.e., water of the United States), and it runs parallel to or along
the stream bed that is within that jurisdictional area. One commenter
stated that installing pipelines that run parallel to a watercourse can
have significant impacts on hydrogeomorphology of the watercourse and
lead to substantial erosion and degradation. A few commenters
recommended retention of the requirement for a PCN when the proposed
activity would run parallel to and within a stream bed, citing the
potential for those activities to downgrade aquatic resource functions.
As discussed in the 2020 Proposal (85 FR 57326), the Corps proposed
to remove this PCN threshold because the text of NWP 12 requires
restoration of these temporary impacts. The third paragraph of NWP 12
addresses the requirements for trenching and backfilling underground
oil or natural gas pipelines to ensure those impacts are temporary and
do not result in a loss of waters of the United States. The ninth
paragraph of NWP 12 also addresses the requirements for restoring
temporary fills, so that those fills do not result in losses of
jurisdictional waters and wetlands. Further, in Corps districts where
the construction of oil or natural gas pipelines in jurisdictional
waters and wetlands parallel to a stream channel have the potential to
cause more than minimal individual and cumulative adverse environmental
effects, division engineers may add regional conditions to NWP 12 to
require PCNs for these activities.
(iv) Permanent access roads are constructed above grade in waters
of the United States for a distance of more than 500 linear feet.
Several commenters said that the PCN requirement for permanent access
roads should be retained to ensure NWP 12 activities not authorize more
than minimal adverse effects. One commenter opposed the removal of the
PCN threshold for associated access roads and culvert-related
activities so that district engineers can evaluate potential impacts to
fish passage.
The PCN threshold for losses of greater than \1/10\-acre of waters
of the United States applies to permanent access roads, and that PCN
threshold is sufficient for providing district engineers with the
opportunity to review those activities to determine if they qualify for
NWP authorization. The Corps is removing this PCN threshold for above-
grade permanent access roads because it is redundant with the \1/10\-
acre PCN threshold. Concerns about potential impacts to fish passage
are addressed by NWP general condition 2. General condition 2 states
that no NWP activity may substantially disrupt the necessary life cycle
movements of those species of aquatic life indigenous to the waterbody,
including those species that normally migrate through the area, unless
the activity's primary purpose is to impound water. Furthermore,
general condition 2 requires all permanent and temporary crossings of
waterbodies to be suitably culverted, bridged, or otherwise designed
and constructed to maintain low flows to sustain the movement of those
aquatic species.
(v) Permanent access roads are constructed in waters of the United
States with impervious materials. A few commenters suggested a maximum
length for impervious surfaces without a PCN associated with NWP 12.
The current PCN requirement for losses of waters of the United States
greater than \1/10\-acre is sufficient to trigger activity-specific
review for permanent access roads constructed with impervious
materials, to allow district engineers to determine whether a
particular proposed access road will result in no more than minimal
adverse environmental effects.
Proposed Addition of a PCN Threshold for New Oil or Natural Gas
Pipeline Activities Greater Than 250 Miles in Length
Many commenters objected to the proposed PCN threshold for new oil
or natural gas pipelines that are greater than 250 miles in length,
stating that it is arbitrary and capricious, and indicated that there
is no reasonable basis for the 250-mile threshold. One commenter
expressed support for the addition of the 250-mile pipeline length PCN
requirement. One of the commenters said that this PCN threshold is
inconsistent with other PCN thresholds. Many commenters objected to
removing the current PCN thresholds and replacing them with the 250-
mile PCN threshold. One commenter expressed support for the proposal to
require that PCNs include information on all discharges associated with
a pipeline, including those that
[[Page 2776]]
would not otherwise require a PCN. One commenter stated that the phrase
``associated with an overall project'' was unclear and undefined.
As discussed in the 2020 Proposal, this PCN threshold is being
added for new oil or natural gas pipelines to provide district
engineers the opportunity to review all crossings of waters of the
United States for new long-distance oil or natural gas pipelines to
ensure that the activities authorized by NWP 12 will result in no more
than minimal individual and cumulative adverse environmental effects
(see 85 FR 57327). Given the concerns expressed by numerous commenters
regarding the potential cumulative adverse environmental effects that
may be caused by NWP 12 activities, this is not an arbitrary or
capricious addition to the PCN requirements for NWP 12. This new PCN
threshold is not a replacement for the PCN thresholds the Corps is
removing from NWP 12. It is a new PCN threshold to address stakeholder
concerns about cumulative effects. The phrase ``associated with an
overall project'' refers to the entire oil or natural gas pipeline that
is greater than 250 miles in length.
Several commenters supported a scope or length-based PCN threshold
but suggested that the Corps adopt more protective PCN thresholds in
place of the proposed 250-mile threshold. One of these commenters said
that significant cumulative environmental impacts are likely to occur
at a much lower length. One of these commenters suggested changing the
distance in this PCN threshold to 25 miles, while another commenter
suggested 75 miles, and a third commenter suggested a 5-mile threshold.
One commenter said that the Corps should require PCNs for any proposed
oil or natural gas pipeline activity resulting in five or more
crossings.
The Corps believes that this new PCN threshold, plus the other two
PCN thresholds in NWP 12 (i.e., activities requiring section 10
authorization, and discharges resulting in the loss of greater than \1/
10\-acre of waters of the United States), are sufficiently protective
of the aquatic environment by providing information to district
engineers to conduct case-specific reviews of proposed NWP 12
activities that have the potential to result in more than minimal
individual and cumulative adverse environmental effects. In furtherance
of the Corps' review of cumulative effects, paragraph (b)(4) of NWP
general condition 32 requires PCNs for proposed NWP activities for
linear projects to include and any other NWP(s), regional general
permit(s), or individual permit(s) used or intended to be used to
authorize any part of the proposed project or any related activity,
including other separate and distant crossings for linear projects that
require Department of the Army authorization but do not require pre-
construction notification. The Corps finds that a length of 250 miles
is both a good indicator of potential cumulative effects of an oil or
natural gas pipeline while minimizing the potential for inconsistent
implementation of the PCN requirement across districts. Although the
Corps agrees that using a threshold of five or more crossings is based
on a numerical impact, it could be more challenging to implement since
there may be proposed oil or natural gas pipeline activities where
there are five or more crossings and none of those crossings require
PCNs.
One commenter suggested replacing the PCN threshold for new oil or
natural pipeline activities with lengths of greater than 250 miles with
a PCN requirement for oil or natural gas pipeline activities that cross
state or district boundaries. Several commenters objected to the
proposed 250-mile PCN threshold, but some of these commenters said that
the acreage PCN threshold is sufficient to ensure no more than minimal
adverse environmental effects. A few commenters remarked that the
length of a pipeline is not a predictor of its crossings of waters of
the United States or environmental impacts and that this PCN threshold
has no link to the Corps' regulatory authority. A few commenters stated
that the 250-mile PCN threshold is inconsistent with the other proposed
utility line activity permits as they do not contain that PCN
threshold. One commenter objected to the 250-mile PCN threshold because
it is limited to new oil or natural gas pipelines (i.e., the material
to be transported after the pipeline is constructed).
As discussed above, the purpose of this new PCN threshold is to
provide information to district engineers to facilitate their review of
the cumulative effects that may be caused by new long-distance oil or
natural gas pipelines that have waterbody crossings that require NWP 12
authorization. These new long-distance oil or natural gas pipelines may
be constructed within a single state or Corps district. The Corps
agrees that the number of aquatic resources and their distribution in
the landscape is variable, and therefore the number of crossings of
waters of the United States is similarly variable. However, the Corps
finds that a length of 250 miles is both a good indicator of potential
cumulative effects of an oil or natural gas pipeline while minimizing
the potential for inconsistent implementation of the PCN requirement
across districts. In addition, some oil or natural gas pipeline
crossings may not require DA authorization because they are installed
through horizontal directional drilling, do not involve a waterbody
subject to Section 10 of the Rivers and Harbors Act, and do not involve
discharges of dredged or fill material into waters of the United
States. The Corps does not believe that this PCN threshold is necessary
for new NWPs 57 and 58 because long-distance electric utility lines are
often constructed as overhead utility lines and utility lines for water
and other substances (e.g., potable water, wastewater, sewage) are
often constructed to serve local communities and thus are likely to be
shorter in overall length.
One commenter stated that the Corps' Regulatory Impact Analysis for
the proposed rule is flawed because it assumes the new 250-mile PCN
requirement would result in no additional PCNs. One commenter said that
if the Corps does move forward with a 250-mile PCN threshold for new
oil or natural gas pipeline activities that applicants be allowed to
provide the PCNs based on desktop data as some areas may not be
accessible for field surveys if the project is in the development
stage. One commenter stated that the 250-mile PCN threshold would
result in the majority of pipeline projects being constructed without
review and would result in damage to historic properties. One commenter
said that the 250-mile threshold has no scientific or technical basis.
The new 250-mile PCN requirement is unlikely to require more PCNs
for NWP 12 activities because the likelihood of a new oil or natural
gas pipeline greater than 250 miles in length not having any crossings
of waters of the United States that require PCNs under the other PCN
thresholds is extremely small. In addition, the requirement to provide
in the PCN the locations and proposed impacts for all crossings of
waters of the United States that require DA authorization, including
those crossings authorized by an NWP would not otherwise require
preconstruction notification, does not trigger a requirement for the
project proponent to submit full PCNs for those other non-PCN crossings
of waters of the United States. This portion of the new PCN requirement
is nearly identical to an existing requirement in paragraphs (b)(4)(i)
and (ii) of general condition 32. Paragraph (b)(4)(i) requires the
project proponent to include in the PCN any
[[Page 2777]]
other NWP(s), regional general permit(s), or individual permit(s) used
or intended to be used to authorize any part of the proposed project or
any related activity, including other separate and distant crossings
for linear projects that require DA authorization but do not require
pre-construction notification.
Furthermore, paragraph (b)(4)(ii) of general condition 32 currently
requires project proponents to include in PCNs for linear projects
where one or more single and complete crossings require pre-
construction notification, the quantity of anticipated losses of
wetlands, other special aquatic sites, and other waters for each single
and complete crossing of those waters and wetlands. This quantification
also must include those single and complete crossings authorized by an
NWP not requiring PCNs. The only additional information required by the
250-mile PCN threshold is the location of all non-PCN crossings. The
Regulatory Impact Analysis for this final rule has been updated to
identify this new PCN threshold as a change. The lack of discussion of
the proposed 250-mile PCN threshold in the Regulatory Impact Analysis
for the proposed rule was an error. When a project proponent develops a
proposal for a new oil or natural gas pipeline, some degree of
environmental analysis and review is needed to determine whether there
are any crossings of waters of the United States that require DA
authorization, and whether any of those crossings require PCNs. The new
PCN threshold should not impose any additional burdens on the regulated
public. New oil or natural gas pipelines must comply with general
condition 20 for historic properties as do all activities authorized by
an NWP.
One commenter objected to the proposed 250-mile PCN threshold, and
limiting it to the installation of new oil or natural gas pipelines
(versus conducting repair or maintenance activities) along the majority
of the distance of the overall project length, stating that a PCN
requirement should be triggered even if short distances of the pipeline
are being replaced. A few commenters stated that the proposed 250-mile
PCN threshold is counter to, and could undermine, the Corps'
longstanding definition of a single and complete linear project, and
would allow district engineers to require individual permits because of
the length of pipeline and cumulative impacts regardless of the
independent utility of the separate and distant crossings.
The maintenance of existing oil or natural gas pipelines is likely
to have fewer adverse environmental effects than the construction of
new oil or natural gas pipelines, because those maintenance activities
occur to existing pipelines for which some degree of adverse
environmental effects has already occurred and a current environmental
setting that includes the existing pipeline. The 250-mile PCN threshold
does not undermine the Corps' definition of single and complete linear
project because each separate and distant crossing of waters of the
United States can continue to be authorized by an NWP. If one crossing
of waters of the United States for an oil or natural gas pipeline
requires an individual permit, then 33 CFR 330.6(d) applies and the
district engineer will determine which activities require individual
permits and which activities can be authorized by an NWP. Section
330.6(d) of the Corps' NWP regulations, as well as Note 2 of NWP 12,
remain in effect. Section 330.6(d) and Note 2 maintain the Corps' long-
standing process regarding the use of NWPs and individual permits to
authorize linear projects such as oil or natural gas pipelines.
One commenter stated that the 250-mile PCN threshold would
discourage pipeline developers from avoiding and minimizing impacts to
waters of the United States, and from planning longer routes to avoid
sensitive resources. One commenter said that the 250-mile PCN threshold
will add an unnecessary layer of uncertainty and litigation risk. One
commenter stated that a 250-mile PCN threshold would authorize
potentially significant pipeline activities without any district or
division review. One commenter stated that oil or natural gas pipelines
greater than 250 miles in length are so large they are bound to cause
more than minimal effects and should not be approved under an NWP. One
commenter stated that the length of the utility line should not be used
as a PCN threshold; environmental conditions and impacts should be used
instead.
Regardless of the addition of the 250-mile PCN threshold, pipeline
developers are still required to comply with paragraph (a) of NWP
general condition 23, which requires project proponents to avoid and
minimize losses of waters of the United States on the project site,
including permanent and temporary losses of those resources. The
purpose of the new PCN threshold is to add a mechanism to provide
information for the district engineer's cumulative effects
determination and the district engineer's decision on whether to issue
NWP verifications for the proposed crossings of waters of the United
States. The information on all of the crossings will inform whether or
not the cumulative adverse environmental effects of all crossings are
or are not more than minimal. This PCN threshold also provides the
district engineer to require an individual permit for the proposed oil
or natural gas pipeline activities when he or she determines the
cumulative adverse environmental effects of the proposed crossings of
waters of the United States are more than minimal. This may help reduce
litigation risk. The 250-mile PCN threshold provides information for
the district engineer's review, who also uses information on current
environmental conditions and potential impacts of the proposed NWP
activities to determine whether NWP authorization is appropriate for
these NWP 12 activities. Division engineers do not have a role in
reviewing NWP PCNs.
Other Provisions of NWP 12
One commenter said that Note 2 should be reissued with no changes,
as it clarifies concepts such as ``single and complete project,''
``single and complete non-linear project,'' ``independent utility,''
and the interaction of the NWPs with individual permits. The Corps has
reissued Note 2 with no changes. Note 2 differs from the 250-mile PCN
threshold in that an individual permit is required for the proposed oil
or natural gas pipeline if one or more crossings of waters of the
United States does not qualify for NWP authorization. Under the 250-
mile PCN threshold, an individual permit is required if the district
engineer determines the cumulative adverse environmental effects of all
crossings of waters of the United States that require DA authorization
will result in more than minimal cumulative adverse environmental
effects.
A few commenters objected to authorizing separate and distant
crossings as single and complete projects. These commenters believe
that the practice causes more than minimal cumulative adverse effects.
A few commenters expressed opposition to allowing multiple ``single and
complete'' project authorizations of the same pipeline to be authorized
by the NWP 12, stating that it would be more appropriate to consider
the entire pipeline as a single and complete project. One of these
commenters said that more individual permits should be required for
these activities.
The authorization of separate and distant crossings of waters of
the United States as single and complete projects for the purposes of
NWP authorization is a long-standing practice consistent with the
Corps' regulations at 33 CFR 330.2(i).
[[Page 2778]]
One commenter expressed concern with the cumulative effects
analyses for multiple single and complete crossings and the inability
to account for NWP activities that do not require PCNs. One commenter
said that the proposed reissuance of NWP 12 is arbitrary and capricious
and in violation of the Clean Water Act because it allows unlawful
piecemealing of large pipelines and other linear projects to avoid
individual permit review. One commenter stated that an entire pipeline
project should be subject to NEPA review, including a cumulative review
of all impacts to waters of the United States.
Paragraph (b)(4) of NWP general condition 32 requires project
proponents to include in PCNs any other NWP(s), regional general
permit(s), or individual permit(s) used or intended to be used to
authorize any part of the proposed project or any related activity,
including other separate and distant crossings for linear projects that
require DA authorization but do not require pre-construction
notification. This information is used by district engineers to
determine whether the proposed activity will result in no more than
minimal individual and cumulative adverse environmental effects.
Activities authorized by NWP 12 are not subject to additional NEPA
review, because Corps Headquarters fulfills the requirements of NEPA
when it finalizes the national decision document for the issuance or
reissuance of the NWP. The national decision document includes an
assessment of effects of the Corps proposed action (i.e., the issuance
or reissuance of the NWPs) in accordance with the Council on
Environmental Quality's definition of ``effects or impacts'' at 40 CFR
1508.1(g) in their NEPA regulations. This analysis of effects or
impacts under NEPA includes the projected use of the NWP over the 5-
year period it is expected to be in effect. For an NWP that authorizes
discharges of dredged or fill material into waters of the United
States, the national decision document also includes a cumulative
impact analysis conducted in accordance with 40 CFR 230.7(b)(3).
One commenter stated that acreage limits and thresholds should
remain constant with separate consideration at each single and complete
crossing of waters of the United States authorized by NWP 12. One
commenter said that each crossing should require a separate permit. One
commenter expressed concern that the phrase ``separate and distant'' is
not defined and would not prevent a pipeline from being used multiple
times in close proximity and/or on the same waterbody under NWP 12.
Another commenter said that no additional definition of ``separate and
distant'' is necessary. One commenter stated that the Corps should
impose an overall limit on cumulative effects allowed for a project
with multiple ``single and complete'' crossings.
Nationwide permit 12 has a \1/2\-acre limit for each single and
complete project. As discussed above, and in 33 CFR 330.2(i), each
separate and distant crossing of waters of the United States may
qualify for a separate NWP authorization. The Corps declines to define
the phrase ``separate and distant'' because what constitutes separate
and distant crossings can vary across the country because of
differences in the distribution of waters and wetlands in the
landscape, local hydrologic conditions, local geologic conditions, and
other factors. What constitutes separate and distant crossings is more
appropriately determined by district engineers on a case-by-case basis.
When reviewing a PCN, the district engineer considers the cumulative
effects of all crossings of waters of the United States for the oil or
natural gas pipeline activity, and applies the 10 criteria listed in
paragraph 2 of Section D, District Engineer's Decision.
One commenter said that Note 4 should refer to the General Bridge
Act of 1946 instead of Section 9 of the Rivers and Harbors Act of 1899.
The Corps has made this change to Note 4.
With respect to Note 5 of this NWP, a few commenters requested that
the Corps provide clarification and examples of exempted utility line
activities under Section 404(f) of the Clean Water Act. One commenter
suggested that the Corps provide examples of utility line activities
that do not qualify for the exemption. In accordance with the 1989
Memorandum of Agreement Between the Department of the Army and the U.S.
EPA Concerning the Determination of the Section 404 Program and the
Application of the Exemptions under Section 404(f) of the Clean Water
Act, the U.S. EPA has the authority to determine which activities are
eligible for the Clean Water Act section 404(f) exemptions.
Comments on Proposal To Issue Separate NWPs for Different Utility Line
Sectors
Many commenters expressed support for dividing oil and natural gas
pipeline activities from other types of utility line activities.
Several commenters acknowledged that the three types of utility lines
are of varying sizes and lengths, constructed with different methods,
and have different relative impacts to streams and wetlands. One
commenter said that the proposed division of NWP 12 into three separate
NWPs ensures that the activities authorized by these NWPs are
substantially similar in nature and will further ensure that each of
the NWPs will have no more than minimal adverse effects on the
environment. One commenter stated that permitting utility line
activities through three separate NWPs helps reduce litigation risk for
some types of utility line activities.
The Corps acknowledges that issuing three separate NWPs for
different types of utility lines helps ensure that the categories of
activities authorized by these NWP are substantially similar in nature
and that they will result in no more than minimal individual and
cumulative adverse environmental effects. The issuance of three NWPs
for different categories of utility line activities may also help
reduce regulatory uncertainty for electric utility line operators,
telecommunications companies, state, tribal, and local water
authorities, and other entities that construct, maintain, and operate
these utility lines. It may also provide diversity and stability to the
NWP program and allow Corps districts to continue to authorize
categories of utility line activities by an NWP in the event that one
of the three NWPs is invalidated or stayed by a federal court. Most of
the past litigation on NWP 12 has been for oil or natural gas
pipelines, not electric and telecommunications lines or utility lines
that convey potable water, wastewater, sewage and other such
substances. Issuing separate NWPs for electric utility line and
telecommunications activities and for utility lines for water and other
substances will help provide some degree of regulatory certainty for
the entities that construct and maintain those types of utility lines.
These separate NWPs will also benefit the people who rely on electric
utility lines and telecommunication lines and utility lines for water
and other substances to deliver energy, information, entertainment,
potable water, and other goods and services. The public will also
benefit from the removal of sewage and wastewater to protect public
health and the environment.
A few commenters requested that if NWP 12 is divided that the Corps
be clear that all provisions relating to substations, foundations, and
access roads, and as well as provisions on inadvertent returns of
drilling fluids, temporary structures and fills (including use of
temporary mats), and accompanying notes, remain with the
[[Page 2779]]
same legal effect and with no additional restrictions. The Corps has
written these three NWPs in a consistent manner to provide a similar
framework for authorizing regulated activities associated with utility
lines, utility line substations, access roads, actions to remediate
inadvertent returns, and the authorization of temporary impacts for
construction and other activities.
One commenter suggested that the Corps issue separate NWPs for
utility lines based on the distinction as to whether they are overhead
utility lines, such as electric and telecommunication lines, or
underground utility lines. One commenter requested that the Corps
change the proposed NWP 12 to authorize ``underground pipeline or
utility line related activities.'' Several commenters said that buried
linear utility lines have substantially similar environmental effects
on waters of the United States. One commenter indicated there is
variability and no reasonable justification for dividing the NWPs based
on above-ground and below-ground activity types. A few commenters said
that the construction of oil, natural gas, water, and other utilities
typically require more ground and vegetation disturbance than the
construction methods for electrical utility lines. These commenters
also stated that electrical utility lines have more flexibility to
avoid aquatic resources, and that discharges of dredged or fill
material associated with electric utility lines typically have a
smaller footprint than they do for other in-ground utility lines. One
commenter said that the Corps should keep all buried, underground
utility lines in NWP 12, rather than create a new NWP for utility line
activities for water and other substances, because best management
practices for protecting waters from trenching or boring for pipes are
similar in nature regardless of the product to be carried in the pipe.
After reviewing the public comments, the Corps determined that
issuing separate NWPs for oil or natural gas pipeline activities,
electric utility line and telecommunications activities, and utility
line activities for water and other substances would be the best
approach for reducing regulatory uncertainty for different utility line
sectors.
One commenter suggested that the Corps further distinguish between
natural gas and petroleum liquids in recognition of the differences in
environmental consequences of potential leaks. One commenter
recommended that the Corps further distinguish between large interstate
natural gas pipelines and smaller intrastate natural pipelines and
service lines.
The Corps does not have the authority to address the environmental
consequences of leaks from oil or natural gas pipelines. Those
environmental consequences are more appropriately addressed by federal,
state, and local government agencies that have the legal authority to
require operators of oil or natural gas pipelines to take actions in
response to leaks.
Many commenters objected to the proposed separation of NWP 12 into
three NWPs and requested that the 2017 NWP 12 be retained in its
historic form. Many of these commenters said that the Corps should
focus its concerns on the environmental impacts of the authorized
activities rather than the type of material transported by various
utility lines. Several commenters objected to the proposed division of
the NWP 12 activities indicating that it would cause additional
complications to permitting utility line activities rather than
streamlining the process. One commenter remarked that there are no
substantive differences between the three proposed NWPs and therefore
issuing separate NWPs is unnecessary. Several commenters said that
issuing three separate utility line NWPs will increase litigation risk
and uncertainty for the regulated public.
As discussed above, the Corps believes that separating NWP 12 into
three different NWPs to authorize utility line activities for different
utility line sectors will help enhance regulatory certainty for utility
line sectors that are not a frequent target for litigation because of
the lower degree of concern about the potential direct and indirect
environmental impacts of the substances those utility line sectors
carry (e.g., electricity, potable water, wastewater). As with any
change in the NWP program, prospective permittees will experience some
challenges associated with those changes, but over time they will
adjust to those changes and can realize the benefits of those changes.
Prior versions of NWP 12 have been subjected to litigation, so the
issuance of three separate NWPs for utility line activities is likely
to pose no greater litigation risk than prior versions of NWP 12.
One commenter said that the Corps only analyzed differences but not
similarities among these different types of utility lines. A few
commenters said that the proposed division of NWP 12 activities is an
abrupt and unjustified departure from the long-standing view that
utility lines are activities that are substantially similar. One of
these commenters said that the proposed change is a departure from the
NWPs that were first promulgated in 1977. A few commenters said that a
general permit should encompass activities that are similar in nature
consistent with Section 404(e) of the Clean Water Act.
When proposing to issue new NWPs for activities that were
authorized by a previous NWP, discussing the differences among those
NWPs and the associated categories of activities is an important part
of explaining the proposed action. The changes are being proposed
through the normal rulemaking process, and are being made in response
to events that have raised concerns about potential increases in
regulatory uncertainty for specific categories of regulated entities.
When the NWPs were first issued in 1977, there were 15 NWPs. When the
NWPs were last issued in December 2016, there were 52 NWPs. The number
of NWPs has increased substantially over time in response to changes in
the Corps Regulatory Program, litigation, studies, and other factors.
The three utility line NWPs being issued in this final rule represent
categories that are similar in nature (i.e., oil/natural gas;
electricity, including communications carried by electricity; and
water, wastewater, sewage, stormwater, and other substances). Section
404(e) of the Clean Water Act does not specify how broad or narrow
categories of activities authorized by NWPs and other general permits
must be. The Corps has substantial discretion to identify categories of
activities that are appropriate for NWPs and other general permits.
One commenter noted that the Corps' response to public comments for
the 2017 NWPs rejected the idea that utility line activities are not
substantially similar, stating that the Corps explained that the agency
interprets the `categories of activities that are similar in nature'
requirement broadly to keep the NWP program manageable in terms of the
number of NWPs. A few commenters said that the history of the NWPs
indicates that there is no prior precedent in past NWP rulemaking for
arbitrarily dividing NWPs that are intended to cover categories of
activities that are similar in nature. One of these commenters further
indicated that the mining NWPs (21, 44, 49, and 50) and the development
NWPs (29 and 39) are not analogous as their development came about
differently, indicating that they largely had to do with the end of NWP
26.
As discussed above, Section 404(e) of the Clean Water Act gives the
Corps substantial discretion in how broad or narrow to define
categories of activities
[[Page 2780]]
for general permit authorization. The proposal to issue three separate
NWPs for utility line activities instead of reissuing NWP to authorize
all utility line activities was made, in part, in response to concerns
about regulatory uncertainty for various utility line sectors. The
proposal is also an opportunity to tailor the NWPs so that they will
authorize activities that have no more than minimal individual and
cumulative adverse environmental effects by making targeted changes to
the text of each of these NWPs, as appropriate.
This proposal is consistent with prior NWP rulemaking efforts, in
which the Corps issued new NWPs to authorize categories of activities
with numerous similarities in the text of the NWP, including acreage
limits and other limits, PCN thresholds, and categories of waters in
which those NWPs may be used to authorize discharges of dredged or fill
material into waters of the United States. For example, in 2007 the
Corps issued two new NWPs to authorize discharges of dredged or fill
material into waters of the United States for coal mining activities
(see 72 FR 11092). The Corps issued NWP 49 for coal remining activities
and NWP 50 for underground coal mining activities. These two coal
mining NWPs were issued even though the Corps had issued and reissued
NWP 21 for surface coal mining activities over time since NWP 21 was
first issued in 1982 (47 FR 31794).
In 2000, the Corps issued five new NWPs and modified six existing
NWPs to replace NWP 26, which authorized discharges of dredged or fill
material into headwaters and isolated waters (65 FR 12818). Four of the
new NWPs (NWP 39 for residential, commercial, and institutional
developments; NWP 40 for agricultural activities; NWP 42 for
recreational facilities; and NWP 43 for stormwater management
facilities) authorized discharges of dredged or fill material into non-
tidal waters of the United States, excluding non-tidal wetlands
adjacent to tidal waters. Each of these NWPs had a \1/2\-acre limit for
losses of non-tidal waters of the United States. The categories of
activities established for these four NWPs were based on the
operational purposes they served, which the Corps does not have the
authority to regulate. Those operational purposes included providing
places for people to live, work, learn, and produce goods and services
(NWP 39); agriculture activities, including farm buildings (NWP 40);
recreational facilities and associated features (NWP 42); and
stormwater management facilities (NWP 43).
Similar to these NWPs, the three NWPs the Corps is issuing to
authorize various sectors of utility line activities are differentiated
by the substances those utility lines carry, despite the Corps' lack of
authority to regulate the substances being conveyed by those utility
lines. If Congress had intended the categories of general permits
issued under Section 404(e) of the Clean Water Act to be based on the
activity the Corps regulates (i.e., discharges of dredged or fill
material into waters of the United States), it would not have written
the text of section 404(e) to refer to ``any category of activity
involving discharges of dredged or fill material.'' The text of section
404(e) clearly allows the Corps to issue any number of NWPs that
authorize discharges of dredged or fill material into waters of the
United States. Furthermore, those categories can be based on how the
authorized activity will be used after the project proponent has
completed the construction activities associated with the discharges of
dredged or fill material into waters of the United States, and how
people will use the completed activities even though the Corps
generally has no authority to regulate how the constructed facilities
are operated. These principles apply to the three NWPs the Corps is
issuing for these three utility line sectors.
One commenter said that the proposed changes to NWP 12 and the
proposed issuance of separate NWPs for other types of utility lines are
not consistent with congressional intent to reduce administrative
burdens and the Administration's policy on infrastructure development
and maintenance. This commenter cited Executive Order 13777,
``Enforcing the Regulatory Reform Agenda'' (February 24, 2017),
Executive Order 13783, ``Promoting Energy Independence and Economic
Growth'' (March 28, 2017), and the 2018 ``Legislative Outline for
Rebuilding Infrastructure in America.''
The Corps believes that this issuance of these three NWPs (NWPs 12,
57, and 58) are consistent with priorities for infrastructure
development because they will help reduce regulatory uncertainty and
burdens on the regulated public. The issuance of these NWPs will not
cause any increases in the number of activities authorized by an NWP or
the number of activities requiring individual permits. The three NWPs
are consistent in general structure, but they have some differences
because of the different types of substances those utility lines convey
and how those utility lines are designed and constructed.
Several commenters stated that the proposed division of NWP 12
activities into separate NWPs discourages the beneficial and common
practice of joint trenching and the use of utility corridors where
various types of utilities are co-located, and further indicated that
these features should be permissible under NWP 12 as a single and
complete project. Several commenters said that the proposal to issue
three separate NWPs would increase costs and delays associated with
energy infrastructure projects. A few commenters stated that the
division of NWP 12 into three NWPs would increase the number of permits
needed by some applicants. One commenter cited NWP general condition 28
as a reason not to divide NWP 12 into three different NWPs for
different types of utility lines.
The issuance of these three NWPs will not discourage joint
trenching and the use of utility corridors for multiple utility lines.
For example, if a project proponent proposes to construct a water line
next to an oil or natural gas pipeline, the provisions of NWP general
condition 28, use of multiple NWPs, would apply. For each crossing of a
separate and distant waterbody, both NWP 58 and 12 could be used, as
long as the loss of waters of the United States at each single and
complete project does not exceed \1/2\-acre. The issuance of these
three NWPs will not cause increased costs and delays for energy
infrastructure projects, except for a relatively brief period of time
as the transition from the 2017 NWPs to the 2021 NWPs occurs. The Corps
acknowledges that there will be some increases in the number of permits
that project proponents will need to obtain, but those permits will
generally be used concurrently, and consistent with general condition
28. The use of multiple NWPs to authorize single and complete projects
is a longstanding practice in the NWP program.
A few commenters said that the when the Corps considers whether to
make changes to an established and well-functioning NWP program, it
should be conscious of how changes to the framework for permitting
utility lines will affect the investment community, and in turn the
country's ability to continue to deliver competitively-priced energy
from diverse sources to U.S. consumers and other end-users, and to
further domestic energy independence. A few commenters remarked that
pipeline and other infrastructure operators need regulatory certainty
to build, maintain, and upgrade pipelines and other utility
infrastructure. One commenter expressed support for the Corps' efforts
to improve the NWP
[[Page 2781]]
program, but cautioned the Corps to avoid changes that could introduce
inefficiencies. A few commenters said that the proposed division of NWP
12 into three separate NWPs would likely introduce unnecessary strain
on agency resources, delays in the permit reviews, regulatory
inconsistency in the permitting process. One commenter objected to
dividing the NWP 12 into three separate NWPs because they are very
similar and can be more easily tracked and understood as one category.
The Corps acknowledges that there will be some challenges and
opportunities with these changes to the NWP program, but it should also
be noted that the NWP program changes each time the Corps goes through
the rulemaking process to issue or reissue the NWPs and that
adjustments need to be made under the new NWPs. The issuance of NWP 57
will help support renewable energy generation facilities and the
transfer of electricity from those generation facilities to
residential, commercial, industrial, and other users. The NWPs will
continue to provide regulatory certainty for pipelines and other types
of utility lines. None of these three NWPs require agency coordination,
so other federal agencies should not be adversely affected by the
splitting of NWP 12 into three separate NWPs.
One commenter said that if the Corps were to move forward with the
division of the NWP 12 activities it must take into consideration the
differences between distribution and transmission pipelines as the
physical characteristics of the pipelines inherent in these different
uses may have a larger effect on waters of the United States than the
material being transported. A few commenters suggested that if NWP 12
were reissued without change, over time the use of NWP 12 would shift
from oil and gas pipelines to other utility sectors to account for new
investment in more secure and resilient utility systems, and that a
two-year period is an inadequate sampling for this decision making
effort.
The Corps does not agree that is necessary to address differences
between distribution and transmission pipelines. These NWPs authorize
utility lines of various sizes, and the Corps focuses its analysis of
potential adverse environmental effects or impacts that are caused by
the activities that are directly related to the Corps' regulatory
authority (i.e., discharges of dredged or fill material into waters of
the United States regulated under Section 404 of the Clean Water Act
and structures and work in navigable waters of the United States
regulated under Section 10 of the Rivers and Harbors Act of 1899). The
Corps does not believe it is useful to engage in speculation about
potential future trends in the number of oil or natural gas pipelines
versus the number of electric utility lines and telecommunications
lines versus the number of utility lines carrying water and other
substances. The Corps estimated the potential permitting changes using
data on NWP verifications issued between March 19, 2017, and March 19,
2019, which provides a robust sample size.
One commenter said that that, according to the Congressional
Research Service, the Corps does not have a centralized database or
other information on the number of individual permits it issues for
pipeline and utility line projects, nor does it have a database on the
utility line activities that are authorized by NWP 12, and that any
attempt by the Corps to draw out a reasoned, data-driven basis for
dividing NWP 12 into three separate NWPs is premature at this time.
The Corps does have a centralized database that tracks NWP
verifications issued, regional general permit verifications issued, and
individual permits issued, including the types of activities authorized
by those general permits and individual permits. From that data, the
Corps was able to estimate the number of NWP activities that were
likely associated with oil or natural gas pipelines, electric and
telecommunications lines, and utility lines for water and other
substances.
One commenter stated that dividing the NWP 12 would add complexity
to ESA and NHPA compliance. One commenter said that the Corps
appropriately recognizes that the techniques used to construct water
and electric utility lines have fewer impacts to waters of the United
States than other uses of NWP 12 involving transport of petrochemicals.
The issuance of these three NWPs will not add complexity to ESA or NHPA
compliance because they must comply with the same NWP general
conditions, including general condition 18, endangered species, and
general condition 20, historic properties. A single compliance process
under either law can serve multiple NWPs for those activities that may
use NWP 12 and 58, for example.
A few commenters stated that there is no logical grouping to be
found for dividing the proposed NWP activities based on pipe diameter,
size, and any associated ground disturbances. A few commenters said
that the Corps' information on diameter and pipeline lengths are based
upon incomplete generalizations that do not withstand scrutiny. One
commenter stated that justification for dividing NWP 12 cannot be based
upon the diameter of the pipeline or conduit. One commenter remarked
that the size of the pipe may determine a minimum width of a trench but
that some smaller pipelines may require larger trenches depending on
the circumstance and that this is not a valid criterion for separating
the NWPs. One commenter said that the Corps failed to make a persuasive
case that length of a utility line would be a determining factor when
considering ground disturbances and division of the NWP activities. One
commenter said that with respect to the Corps' jurisdiction under
Section 10 of the Rivers and Harbors Act of 1899, it is the presence of
a pipeline that affects navigation, not the substance it contains.
The discussion in the preamble to the 2020 Proposal regarding the
differences among the three utility line sectors that were the basis
for the modified NWP 12 and the proposed new NWP C and D was intended
to demonstrate that there are some differences among those sectors. The
final NWPs are based on sectors, not construction techniques or sizes
of the utility lines. The text of the three NWPs makes no references to
the diameters or length of the utility lines. The Corps agrees that for
utility lines that cross navigable waters of the United States and
require section 10 authorization, the Corps focuses its evaluation on
potential effects on navigation, not the substance being conveyed by
the utility line.
A few commenters said that the Corps' jurisdiction as related to
these NWPs is limited to its statutory authorities under Section 404 of
the Clean Water Act and Section 10 of the Rivers and Harbors Act of
1899. One commenter expressed concern that the proposed issuance of
separate NWPs could lead the Corps to consider factors outside of its
statutory authority. A few commenters stated that consideration of the
type of substances that can be conveyed by a utility constitutes
overreach of the Corps' statutory jurisdiction. These commenters went
on to reference statements from the Corps that it does not regulate the
operation of oil and natural gas pipelines, but that the Corps
regulates discharges of dredged or fill material into waters of the
United States associated with their construction.
The Corps recognizes that under these three NWPs the Corps'
statutory authority is limited to Section 404 of the Clean Water Act
and Section 10 of the Rivers and Harbors Act. However, for these three
NWPs and many of the other NWPs, the categories of activities
authorized by those NWPs relate to how
[[Page 2782]]
the constructed activities will be used (e.g., residences for NWP 29,
recreational facilities for NWP 42, land-based renewable energy
generation for NWP 51), even though the Corps does not have the
authority to regulate the operation of the constructed structure or
fill. As discussed above, the text of section 404(e) recognizes that
the Secretary could issue any number of general permits, including
NWPs, for any number of categories of activities involving discharges
of dredged or fill material into waters of the United States.
A few commenters said that the terms used to describe the
applicability of NWP 12 cause ambiguous situations with respect to
which substances would qualify as oil, gas, or petrochemicals and to
which NWP would apply. These commenters also indicated confusion
associated with common situations where petrochemical products are
added to non-petroleum products prior to transport and generally
suggested the source of the material to be transported has little or no
bearing on the methods for construction, maintenance, repair or
replacement of the pipeline on the best management practices needed to
protect waters of the United States.
The Corps has attempted to provide more clarity regarding the
differentiation of utility line sectors that would fall under NWPs 12,
57, or 58. The Corps recognizes that there may be situations where a
prospective permittee may be unsure which NWP applies. The prospective
permittee could coordinate with the appropriate Corps district to get
assistance in identify which NWP would be most appropriate for a
particular project. If the project proponent is contemplating
constructing different types of utility lines for a particular project,
multiple NWPs could be used as long as the project proponent complies
with NWP general condition 28, which addresses use of multiple NWPs for
a single and complete project.
General Comments on Best Management Practices
A few commenters supported the incorporation of specific best
management practices (BMPs) for the utility line NWPs. A few commenters
said that adding additional BMPs or standards to this NWP would result
in redundant requirements to manage on these projects without providing
additional benefits. A few commenters said that division engineers can
tailor standards to meet region-specific needs and issue additional
regional conditions with their discretionary authority. One commenter
stated that the BMPs for protecting water features during trenching,
boring, or sleeving construction methods for installing, replacing, or
maintaining pipes at stream or wetland crossings are similar in nature,
regardless of what product will travel in the pipeline once
construction is completed. One commenter stated that the three
categories of utility lines under proposed NWPs 12, C, and D, would
authorize sufficiently similar activities and require the same or
similar environmental provisions in order to meet the no more than
minimal impacts requirement under section 404(e) of the Clean Water
Act. One commenter said that because of the overarching federal
regulatory regime, NWP 12 and its general conditions, regional
conditions added by division engineers, and applicable state
requirements there are no additional BMPs that could be practically or
lawfully added to NWP 12.
The Corps agrees that there are no national best management
practices to add to NWPs 12, 57, and 58. As discussed below, a few
commenters submitted suggestions for best management practices. The
Corps has considered those best management practices, and has concluded
that best management practices are more appropriately addressed as
regional conditions added to the NWPs by division engineers or
activity-specific conditions added NWP authorizations by district
engineers.
A few commenters said that imposing additional best management
practice requirements would risk conflict or redundancy with other
applicable regulations. A few commenters suggested that the if the
Corps were to become aware of best management practices to add to NWP
12 then it should conduct a subsequent notice and comment procedure for
these BMPs as none were specifically proposed. A few commenters
indicated that a 60-day notice is inadequate for stakeholders and
agencies to compile BMPs and best available science for the invitation
to comment. One commenter recommended that the Corps maintain the
existing NWPs and instead conduct an extensive outreach campaign to
stakeholders to determine BMPs for the utility line NWPs. One commenter
said that when developing industry specific standards and BMPs, the
duration and location of temporary fill impacts across a project site
should be taken into consideration. One commenter requested that the
Corps provide examples the types of construction methods for access
roads that are considered to minimize adverse effects to waters of the
United States as noted in several NWPs.
The Corps has decided not to add any best management practices to
NWPs 12, 57, and 58. After reviewing the BMPs suggested by commenters,
the Corps determined that the text of these NWPs already include some
common BMPs, such as requiring the top 6 to 12 inches of the trench to
normally be backfilled with topsoil from the trench, constructing the
trench so that it does not drain waters of the United States through a
French drain effect, or stabilizing exposed slopes and stream banks
immediately after completion of construction of the stream crossing.
Comments on Best Management Practices for NWP 12
One commenter said that impacts from work on natural gas pipelines
and gas utility lines are minimal and temporary, and BMPs under the
existing NWP 12 protect waters of the United States. One commenter
stated that if the Corps decides to impose any BMPs on interstate
natural gas pipelines they must not conflict with the FERC's Plan and
Procedures. Several commenters stated that The U.S. Department of
Transportation (DOT) Pipeline and Hazardous Materials Safety
Administration (PHMSA) Office of Pipeline Safety imposes stringent
pipeline safety regulations under 49 CFR part 192 on natural gas
interstate transmission pipelines and gas utility intra-state natural
gas transmission and distribution utility lines. One commenter stated
that the 2017 NWP 12 provides adequate environmental protections under
Section 404 of the Clean Water Act and Section 10 of the Rivers and
Harbors Act of 1899, and that no additional industry-specific standards
or BMPs should be added to the NWPs as national enforceable terms. One
commenter stated that pipeline rights-of-way should be maintained in
herbaceous condition within 10-feet centered on the pipeline. One
commenter stated that applicants should have to produce containment and
clean up contingency plans as BMPs for all of the utility line permits.
One commenter said that a trench should not be constructed or
backfilled in a matter that would redirect shallow groundwater flow
paths, to avoid altering vegetative communities or flow in streams
downslope of the trenches. One commenter said that appropriate measures
should be taken to maintain water quality conditions downstream of the
site.
As discussed above, the Corps is not adding any BMPs to the text of
NWPs
[[Page 2783]]
12, 57, and 58 that were not in the proposed texts of these NWPs.
Best management practices recommendations. One commenter said that
a list of BMP manuals that support oil and gas pipeline development and
maintenance activities in Appendix G of the document titled
``Considering Best Practices for Managing Pipeline Permitting.''
Several of these documents are excellent resources for best management
practices related to impacts to wetlands and streams. One commenter
recommended the following BMPs for NWP 12:
All excavations should be backfilled with the excavated
material after installation of the appropriate structures.
Side-cast spoil material from trench excavation should be
placed on the side of the trench opposite streams and wetlands.
Spoil material from trench excavation should be placed on
the side of the trench to be reused as backfill with the A-horizon
placed back in its original position.
Excess spoil material must be removed to an approved
upland disposal site.
Stream banks at crossings must be restored after
construction has been completed.
Disturbed stream banks can be restored by planting woody
vegetation and by using bioengineering techniques for stream bank
stabilization.
Right-of-ways through and adjacent to streams and through
forested wetlands should be maintained in low growing, woody vegetation
to minimize erosion and sedimentation. Maintenance of this right-of-way
should be conducted with mowing rather than with chemicals to reduce
the potential for contamination and negative impacts on aquatic
resources.
If chemicals are used, a 50-foot buffer on either side of
the stream crossing should be established in order to retain the
riparian vegetation while reducing the amount of chemical runoff into
the aquatic environment.
Any open trench must be temporarily fenced to reduce the
likelihood of wildlife becoming trapped and must include a ramped
section which would allow wildlife to escape.
A full visual inspection of every open trench section must
be made daily to identify any trapped wildlife in need of rescue.
One commenter provided an example list of industry BMPs, but
indicated that should the Corps chose to incorporate them in the text
of NWP 12 and the other utility NWPs, it must understand that all BMPs
are not appropriate to all circumstances. This commenter provided the
following list of BMPs:
Requiring, where appropriate, a plan to address the
prevention, containment, and cleanup of sediment or other materials
caused by inadvertent returns of drilling fluids.
Requiring notification to the Corps and implementation of
a remediation plan in the event of an inadvertent return of drilling
fluids.
Siting poles and tower foundations outside of surface
waters where practicable.
Visually marking waters of the United States near work
areas.
Using techniques that minimize rutting and damage to
wetlands, such as installing mats prior to placing or driving equipment
over wetlands or streams for temporary access or using wide-track
equipment.
Establishing stockpiling/work areas outside of surface
waters.
Construction monitoring during routine inspection and
maintenance activities to avoid unauthorized discharges into surface
waters.
A few commenters suggested modifying the text of NWP 12 to
encourage the use of directional drilling. One commenter said that when
horizontal directional drilling (HDD) is not possible, the flume method
should be the required method for use of the NWP 12 over the dam-and-
pump or open-cut stream crossing methods in order to minimize impacts
to aquatic resources. One commenter suggested when HDD is used the
permittee should erect sediment control measures between the drill site
and nearby sensitive resources to prevent drilling mud releases from
reaching sensitive resources, conduct regular on-site briefings for
personnel to identify and locate sensitive resources, and maintain
response equipment on-site or in an accessible location and in good
working-order. One commenter suggested that HDD contractors should be
required to employ a full-time, qualified on-site mud engineer to
continuously monitor the drilling fluid circulation and returns as a
preventative measure.
The Corps declines to add text to NWPs 12, 57, and 58 to encourage
horizontal directional drilling. The use of horizontal directional
drilling is more appropriately determined on a case-by-case basis. The
Corps lacks the authority to require HDD contractors to employ a full-
time, qualified on-site mud engineer to monitor drilling fluid
circulation and potential inadvertent returns of drilling fluid.
One commenter said that Congress did not intend the NWP program to
be used to streamline the authorization of major infrastructure
projects and that each water crossing for major pipeline projects that
transport highly toxic and dangerous materials should require
individual permit reviews. A few commenters stated that environmental
impact statements should be required for oil or natural gas pipelines.
One commenter said that a programmatic ESA consultation should be
completed for this NWP. One commenter stated that the construction and
operation of oil and gas pipelines pose significant risk to protected
species and should require individual permits. Another commenter said
that the Corps must determine the environmental safety of HDD at a
particular location and associated mitigation measures. One commenter
suggested a definition for ``stand-alone project'' to require that all
the crossings within major watersheds are evaluated together as single
and complete since the cumulative impacts would be to one system.
Section 404(e) of the Clean Water Act provides the Corps with the
authority to issue NWPs to authorize categories of activities involving
discharges of dredged or fill material into waters of the United States
to streamline the authorization process for these activities, as long
as they result in no more than minimal individual and cumulative
adverse environmental effects. Section 404(e) does not prohibit the
issuance of general permits for utility lines and other infrastructure
projects. As many commenters recognized, the Corps does not have the
discretion to control the types of substances conveyed by oil or
natural gas pipelines or other types of utility lines. Compliance with
the Endangered Species Act is discussed in Section III.D of this final
rule: Compliance with Relevant Statutes. The Corps declines to add a
definition of ``stand-alone project'' because cumulative impacts are
already evaluated by district engineers over appropriate geographic
regions, such as watersheds, Corps districts, states, etc.
A few commenters stated that NWP 12 should be revised to consider
the protection of tribal treaty rights. One commenter said that the
Corps should conduct tribal consultation for the reissuance of the NWP
12. One commenter suggested the Corps adopt a policy of early
consultation with Indian Tribes and other actors on these types of
projects, above the timeline required by the NHPA section 106 process
to allow the Corps to preemptively address concerns and avoid delays,
litigation, and other increased costs. One commenter said that the
draft NWP 12 decision document fails to address the
[[Page 2784]]
high correlation of pipeline construction projects with rates of
missing and murdered Indigenous women and children and indicated that
the Corps had not consulted the tribes on the matter. One commenter
stated that there are a variety of utility lines that have direct,
indirect, and cumulative impacts on treaty reserved resources and that
the proposed changes require additional review to fully understand the
extent of potential resource impacts. One commenter requested the Corps
continue to require PCNs in Washington State to adequately protect
treaty resources.
Tribal treaty rights are addressed through NWP general condition 17
for all NWPs, including NWP 12. Consultation with tribes on the
proposed NWPs is discussed in Section V of this final rule
(Administrative Requirements), in the section for E.O. 13175. The draft
decision document does not discuss pipeline construction projects and
missing and murdered people because that issue is more appropriately
addressed by local, state, tribal, and federal law enforcement
officials. Concerns about potential impacts to treaty resources in
Washington State are more appropriately addressed through regional
conditions, which can add PCN requirements to this NWP, where
appropriate.
This NWP is reissued with the modifications discussed above.
(2) NWP 21. Surface Coal Mining Activities
The Corps proposed to modify this NWP to remove the 300 linear foot
limit for losses of stream bed (discussed above in Section II.F),
remove the reference to integrated permit processing procedures, and
remove the requirement for the permittee to obtain written verification
from the district engineer so that the 45-day PCN review period would
apply to this NWP as it does to other NWPs with \1/2\-acre limits for
losses of waters of the United States. Comments received on the
proposed removal of the 300 linear foot limit for losses of stream bed
are summarized in Section II.F of this final rule, and in that section
the Corps provided responses to those comments.
Many commenters opposed removing the provision that requires a
written verification from the district engineer before commencing the
authorized activity, instead of allowing a default authorization to
occur if the Corps does not respond to a complete PCN within 45 days.
Several commenters expressed support for the default authorization to
occur if the district engineer does not respond to the PCN within 45
days. Many commenters opposed removal of the PCN requirements from this
NWP. One commenter said that in order to further expedite permitting
for a coal mining project, no PCNs should be required.
The Corps removed the requirement for the permittee to obtain
written authorization before commencing the activity to be consistent
with the other NWPs that have a \1/2\-acre limit for discharges of
dredged or fill material into non-tidal waters of the United States
(e.g., NWPs 29, 39, 40, 42, 43, 44, 51, and 52). The Corps did not
propose to remove any PCN requirements from this NWP. All activities
authorized by this NWP require PCNs.
One commenter stated support for the language regarding integrated
permitting processing procedure language. One commenter requested
addition of text to the NWP stating that no work can begin until
formally approved by the U.S. Department of Interior or the state, and
final approval is not necessary before submitting a PCN to the district
engineer. One commenter said that NWP 21 should be expanded to include
a requirement for federal and state agency coordination when pitcher
plant bog wetlands, bald cypress, and/or tupelo swamps are impacted.
This commenter also stated that this NWP should not authorize
discharges of dredged or fill material into these types of wetlands.
The Corps removed the language referencing integrated permit
processing procedures, since those procedures have never been developed
for this NWP since that text was added to the NWP in 2007 (see 72 FR
11184). Project proponents may be required to obtain separate
authorizations from the Department of Interior's Office of Surface
mining or the state, but those authorizations are a separate process
from the Corps' NWP authorization process. Authorization by an NWP does
not obviate the need to obtain other federal, state, or local permits,
approvals, or authorizations required by law. (See item 2 in Section E,
Further Information.) Division engineers can add regional conditions to
this NWP to restrict or prohibit discharges of dredged or fill material
into certain wetland types if those discharges are likely to result in
more than minimal individual and cumulative adverse environmental
effects. District engineers can also exercise discretionary authority
to modify, suspend, or revoke an NWP after reviewing the PCN, to ensure
that the NWP authorizes only those activities that result in no more
than minimal individual and cumulative adverse environmental effects.
Several commenters said that NWP 21 should be revoked because the
adverse effects of surface coal mining on the environment are
significant. One commenter objected to the removal of stream mitigation
requirements. One commenter said that the applicant should be required
to ensure that toxic substances are not released back into the water
column through re-exposure from dredge activities. Several commenters
said that the proposed changes to this NWP unlawfully put the interests
of the regulated public above the Corps statutory mandate to protect
the environment.
The activities authorized by this NWP cannot result in the loss of
greater than \1/2\-acre of non-tidal waters of the United States,
excluding non-tidal wetlands adjacent to tidal waters. In addition, all
activities authorized by this NWP require PCNs. The \1/2\-acre limit,
the PCN requirements, and the ability of division and district
engineers to modify, suspend, or revoke this NWP on a regional or
activity-specific basis ensure that the activities authorized by this
NWP result in no more than minimal adverse environmental effects. The
Corps did not propose to remove any stream mitigation requirements from
this NWP. Despite the changes to this NWP, these activities are
reviewed by district engineers on a case-by-case basis since all
activities require PCNs.
This NWP is reissued as proposed.
(3) NWP 29. Residential Developments
The Corps proposed to modify this NWP to remove the 300 linear foot
limit for losses of stream bed. The Corps also proposed to remove the
ability for district engineers to waive the 300 linear foot limit for
losses of intermittent and ephemeral stream bed. Comments received on
the proposed removal of the 300 linear foot limit for losses of stream
bed are summarized in Section II.F of this final rule, and in that
section the Corps provided responses to those comments.
One commenter said that this NWP should clarify that the acreage
limits are applied cumulatively for both the original construction and
any subsequent expansion of the development. One commenter stated that
this NWP should not be issued to developments proposed in channel
migration zones and floodplains where projects can directly and
indirectly impact essential fish habitat, critical habitat, and
habitats occupied by federally threatened or endangered species. One
commenter said that as a result of climate change, residential
[[Page 2785]]
developments have increased the public safety risk. One commenter asked
if projects occurring in floodplains and authorized by this NWP are
consistent with the 2008 biological opinion on the Federal Emergency
Management Agency's National Flood Insurance Program.
This NWP includes a subdivision provision, which states that for
residential subdivisions, the aggregate total loss of waters of the
United States authorized by this NWP cannot exceed \1/2\-acre,
including any loss of waters of the United States associated with the
development of individual subdivision lots. Activities authorized by
this NWP must comply with general condition 10, fills within 100-year
floodplains. If the district engineer reviews the PCN and determines
that the proposed activity may adversely affect essential fish habitat,
he or she will initiate essential fish habitat consultation with the
NMFS. If the district engineer reviews the PCN and determines the
proposed activity may affect ESA-listed species or designated critical
habitat, she or he will initiate section 7 consultation with the U.S.
FWS and/or NMFS as appropriate (see general condition 18). Potential
public safety risks associated with residential developments are more
appropriately addressed by local or state land use planning and zoning
agencies. The 2008 biological opinion on the Federal Emergency
Management Agency's National Flood Insurance Program only applies to
that program. It does not directly apply to the Corps' NWP program.
One commenter said that authorizing residential developments with
golf courses results in devastating impacts on the environment through
habitat loss and fragmentation, nutrient loading that causes algal
blooms, and the use of pesticides/herbicides, which must be considered
under an environmental impact statement, and therefore, should require
an individual permit. One commenter stated that a \1/2\-acre loss of
waters of the United States is not minimal and that any loss over \1/
10\-acre should require compensatory mitigation. One commenter said
that compensatory mitigation should be required for all unavoidable
impacts to wetlands and streams authorized by this NWP. One commenter
said that if the Corps does not require compensatory mitigation under
NWP 29, the adverse environmental effects are more than minimal. One
commenter said that the reliance on compensatory wetland mitigation
often leads to a net loss of wetland functions and values and that NWPs
like NWP 29 could lead to the loss of thousands of acres of wetlands.
The Corps regulates discharges of dredged or fill material into
waters of the United States, and this NWP limits those discharges to
non-tidal waters of the United States. If the proposed NWP 29 activity
includes the construction of a golf course, the district engineer will
review the PCN and determine whether the proposed activity qualifies
for NWP authorization. The Corps does not have the authority to
regulate the use of pesticides or herbicides, and therefore is not
required to consider the potential use of pesticides or herbicides when
reviewing PCNs for proposed activities. Nutrient loading can be the
result of non-point source pollution. Nutrient loading may also result
from discharges of certain substances from point sources regulated
under Section 402 of the Clean Water Act, which is administered by
states with approved programs or the U.S. EPA. General condition 23
requires compensatory mitigation for all wetland losses greater than
\1/10\-acre that require PCNs, unless the district engineer determines
that some other form of mitigation would be more environmentally
appropriate. Wetland compensatory mitigation projects required for
activities authorized by the NWPs must comply with the Corps'
regulations at 33 CFR part 332, which require monitoring and other
actions to ensure that the required compensatory mitigation offsets the
permitted wetland losses.
One commenter said the array of wetland and water types that
authorized under NWP 29 and lost are varied and that the Corps cannot
determine environmental effects are minimal when they are speculative
and unquantifiable. One commenter stated that the cumulative impacts of
authorizing large residential driveways in waters of the United States
threatens nearshore benthic habitat that is important to salmonids. One
commenter said that it is unclear how permit authorizations are
coordinated with local agencies to ensure the appropriate use of NWP 29
and that local protections should apply to the permit.
All activities authorized by this NWP require PCNs. Therefore,
district engineers review all proposed activities and determine whether
those activities qualify for NWP authorization. When reviewing PCNs,
district engineers consider cumulative adverse environmental effects
caused by activities authorized by an NWP and whether those cumulative
adverse effects are no more than minimal (see paragraph 2 of Section D,
District Engineer's Decision). If the proposed NWP activity may affect
ESA-listed species, including list salmon species, the district
engineer conducts ESA section 7 consultation with the U.S. FWS or NMFS,
as appropriate. Nationwide permit 29 authorizations are not coordinated
with local agencies. As stated in Section E, Further Information, the
NWPs do not obviate the need to obtain other federal, state, or local
permits, approvals, or authorizations required by law.
This NWP is reissued as proposed.
(4) NWP 39. Commercial and Institutional Developments
The Corps proposed to modify this NWP to remove the 300 linear foot
limit for losses of stream bed. The Corps also proposed to remove the
ability for district engineers to waive the 300 linear foot limit for
losses of intermittent and ephemeral stream bed. Comments received on
the proposed removal of the 300 linear foot limit for losses of stream
bed are summarized in Section II.F of this final rule, and in that
section the Corps provided responses to those comments.
Several commenters recommended establishing tailored PCN thresholds
for NWP that are similar to the PCN thresholds in NWP 12, NWP 14, and
NWP 51, which only require PCN for losses of waters of the United
States greater than \1/10\-acre. Due to the current requirement for
PCNs for all NWP 39 activities, this NWP is underutilized and
increasing the PCN threshold to \1/10\-acre would incentivize project
proponents to reduce impacts. A couple of commenters said that
compensatory mitigation should be required for all unavoidable impacts
to streams, wetlands, and special aquatic sites authorized by NWP 39.
One commenter stated that commercial developments have the potential to
cause significant environmental harm through habitat loss and
fragmentation and should be assessed in environmental impact statements
and through programmatic ESA section 7 consultations. One commenter
said that commercial developments constructed in channel migration
zones and floodplains, areas occupied or critical to salmon
populations, should be required to obtain individual permits.
The Corps believes that this NWP should continue to require PCNs
for all activities, so that district engineers can review all proposed
commercial and institutional developments involving discharges of
dredged or fill material into waters of the United States and determine
which proposed activities can be authorized by NWP 39 and which
proposed activities should require individual permits. The streamlined
authorization process
[[Page 2786]]
provided by NWP 39 continues to incentivize project proponents to
reduce losses of waters of the United States to qualify for NWP
authorization instead of having to obtain individual permits for those
activities, and the increased time and paperwork needed to secure those
individual permits. When evaluating PCNs, district engineers determine
whether proposed NWP 39 activities should require compensatory
mitigation or other forms of mitigation to ensure that those activities
result in no more than minimal adverse environmental effects.
Compensatory mitigation requirements are determined on a case-by-case
basis by district engineers. If the district engineer determines a
proposed NWP 39 activity will result in more than minimal adverse
environmental effects after considering mitigation proposed by the
permit applicant, he or she will exercise discretionary authority and
require an individual permit for the proposed activity. During the
individual permit process, the district engineer will determine whether
NEPA compliance will be achieved through the preparation of an
environmental impact statement or environmental assessment, unless the
proposed activity qualifies for a categorical exclusion. The district
engineer will also evaluate the PCN to determine if the proposed
activity may affect listed species or designated critical habitat, and
thus require ESA section 7 consultation with the U.S. FWS or NMFS, as
appropriate. Activities authorized by this NWP must comply with general
condition 10, fills in 100-year floodplains.
This NWP is reissued as proposed.
(5) NWP 40. Agricultural Activities
The Corps proposed to modify this NWP to remove the 300 linear foot
limit for losses of stream bed. The Corps also proposed to remove the
ability for district engineers to waive the 300 linear foot limit for
losses of intermittent and ephemeral stream bed. Comments received on
the proposed removal of the 300 linear foot limit for losses of stream
bed are summarized in Section II.F of this final rule, and in that
section the Corps provided responses to those comments.
One commenter stated that losses of waters and wetlands up to \1/
2\-acre are not minimal. One commenter said that any impacts greater
than \1/10\-acre should require compensatory mitigation. Another
commenter said that this NWP and other NWPs does not adequately address
cumulative impacts and these activities should require individual
permits. One commenter requested that the Corps require best management
practices to prevent and reduce non-point source pollution associated
with agricultural activities. One commenter said that all agricultural
activities authorized by this NWP should go through an alternatives
analysis for channelization or dam construction to support fish passage
and healthy stream systems. One commenter stated that the authorization
of some activities under this NWP, such as levees, is inconsistent with
Federal Emergency Management Agency flood requirements or policies. One
commenter said that allowing these impacts under current watershed
conditions and salmon population status is excessive.
All activities authorized by this NWP require PCNs. District
engineers will review each proposed activity and determine which
activities will result in no more than minimal individual and
cumulative adverse environmental effects and are authorized by this NWP
and which activities do not qualify for NWP authorization and should
require individual permits. During their reviews of PCNs, district
engineers consider cumulative impacts caused by activities authorized
by this NWP (see paragraph 2 of Section D, District Engineer's
Decision). The Corps lacks the authority to require agricultural
producers to implement best management practices to control non-point
source pollution. The NWPs do not require alternatives analyses since
they can only authorize activities that have no more than minimal
adverse environmental effects. If a project proponent is considering
channelizing a stream or constructing a dam, the district engineer will
review the PCN and determine whether the proposed activity will result
in no more than minimal adverse environmental effects. Activities
authorized by this NWP must comply with general condition 10, fills in
100-year floodplains. The Corps does not have the discretion to enforce
flood requirements or policies adopted by the Federal Emergency
Management Agency. If the district engineer determines that a proposed
NWP 40 activity may affect salmon listed under the ESA, he or she will
conduct ESA section 7 consultation with the U.S. FWS or NMFS, as
appropriate, before issuing an NWP verification letter.
This NWP is reissued as proposed.
(6) NWP 42. Recreational Facilities
The Corps proposed to modify this NWP to remove the 300 linear foot
limit for losses of stream bed. The Corps also proposed to remove the
ability for district engineers to waive the 300 linear foot limit for
losses of intermittent and ephemeral stream bed. Comments received on
the proposed removal of the 300 linear foot limit for losses of stream
bed are summarized in Section II.F of this final rule, and in that
section the Corps provided responses to those comments.
One commenter said that large recreational facilities (golf
courses) or non-passive recreational facilities should require
individual permits in non-tidal waters and stream channels, in channel
migration zones, and waters used or in the historic range of listed
species, or that directly or indirectly impact critical or essential
fish habitat. Allowing these impacts under current watershed conditions
and salmon population status is excessive.
This NWP requires PCNs for all proposed activities. District
engineers will review all PCNs to determine whether the discharges of
dredged or fill material into waters of the United States to construct
or expand recreational facilities will result in no more than minimal
adverse environmental effects. If the district engineer determines a
proposed activity may affect ESA-listed species or designated critical
habitat, she or he will conduct ESA section 7 consultation with the
U.S. FWS or NMFS, as appropriate, prior to issuing the NWP verification
or deciding whether to exercise discretionary authority to require an
individual permit. If the district engineer reviews the PCN and
determines the proposed activity may adversely affect essential fish
habitat, he or she will conduct essential fish habitat consultation
with the NMFS.
This NWP is reissued as proposed.
(7) NWP 43. Stormwater Management Facilities
The Corps proposed to modify this NWP to remove the 300 linear foot
limit for losses of stream bed. The Corps also proposed to remove the
ability for district engineers to waive the 300 linear foot limit for
losses of intermittent and ephemeral stream bed. Comments received on
the proposed removal of the 300 linear foot limit for losses of stream
bed are summarized in Section II.F of this final rule, and in that
section the Corps provided responses to those comments. In the first
paragraph of this NWP, the Corps also proposed to add the phrase ``such
as features needed'' before ``to meet reduction targets established
under Total Maximum Daily Loads set under the Clean Water Act.''
One commenter supported adding the phrase ``such as features
needed'' to the first paragraph to clarify that green infrastructure
type of features are not just to reduce total maximum daily loads.
Several commenters said that this
[[Page 2787]]
NWP should be reissued with no changes except for a clarifying
provision related to green infrastructure as states and municipalities
may require or allow green infrastructure projects to meet water
quality criteria, designated uses, and compliance with post-
construction stormwater requirements regardless of whether a total
maximum daily load applies to the receiving water.
The Corps has added the phrase ``such as features needed'' to this
NWP. The Corps agrees that states and municipalities may require, under
their authorities, the construction and implementation of green
infrastructure projects to meet water quality criteria, designated
uses, and compliance with post-construction stormwater requirements. If
the construction and maintenance of those green infrastructure projects
involves discharges of dredged or fill material into waters of the
United States, this NWP can be used to authorize those activities.
One commenter said that for new stormwater management facilities,
best management practices are required as a general matter to prevent
non-point source pollution during and after construction activities.
One commenter stated that allowing the loss of \1/2\-acre of non-tidal
waters under current watershed conditions and salmon population status
is excessive. This commenter said that these facilities should not be
located in wetlands or intermittent or ephemeral streams adjacent to
perennial streams that are occupied by salmon, especially ESA-listed
species. This commenter asserted that these actions should require
individual permits when located in channel migration zones, or
floodplains, wetlands, and essential fish habitat.
Measures undertaken to prevent non-point source pollution during
and after construction activities may be required by state or local
governments, or by other federal agencies. The Corps does not have the
authority to regulate non-point source pollution that may reach waters
and wetlands. Except for certain maintenance activities, all activities
authorized by this NWP require pre-construction notification to the
district engineer. For those activities that require PCNs, the district
engineer will evaluate potential impacts to salmon, and if the salmon
include ESA-listed species, the district engineer will determine if the
proposed activity may affect listed salmon, and engage in ESA section 7
consultation with the U.S. FWS or NMFS as appropriate. Activities
authorized by this NWP must comply with general condition 10, fills in
100-year floodplains. If, during the review of a PCN, the district
engineer determines the proposed activity may adversely affect
essential fish habitat, she or he will initiate essential fish habitat
consultation with the NMFS.
This NWP is reissued as proposed.
(8) NWP 44. Mining Activities
The Corps proposed to modify this NWP to remove the 300 linear foot
limit for losses of stream bed. The Corps also proposed to remove the
ability for district engineers to waive the 300 linear foot limit for
losses of intermittent and ephemeral stream bed. Comments received on
the proposed removal of the 300 linear foot limit for losses of stream
bed are summarized in Section II.F of this final rule, and in that
section the Corps provided responses to those comments. In addition,
the Corps proposed to modify paragraph (b) of this NWP to apply the \1/
2\-acre limit to work in non-tidal navigable waters of the United
States (i.e., section 10 waters).
One commenter said the Corps should not reissue NWP 44 because it
is in violation of Section 404(e) of the Clean Water Act. A few
commenters stated that NWP 44 poses a risk of significant direct and
cumulative harm and these activities should be authorized by individual
permits, not an NWP. One commenter recommended requiring applicants
ensure that toxic substances are not released back into waters through
re-exposure from dredging.
All activities authorized by this NWP require PCNs. District
engineers will review PCNs for proposed activities to ensure that those
activities will result in no more than minimal individual and
cumulative adverse environmental effects, and therefore comply with
section 404(e) of the Clean Water Act.
One commenter said that the Corps should allow use NWP 44 in tidal
waters to reduce cost and time associated with obtaining individual
permits. One commenter expressed support for including activities in
non-tidal section 10 waters. One commenter stated that the addition of
activities in non-tidal section 10 waters needs clarification. This
commenter said this may be a new requirement that is not currently
regulated and thus may impact industrial mineral mining.
Mining activities in tidal waters have potential for causing more
than minimal individual and cumulative effects, and from a national
perspective should be evaluated under the individual permit process.
However, district engineers can develop and issue regional general
permits to authorize mining activities in tidal waters in areas where
these activities usually result in no more than minimal adverse
environmental effects. The Corps is retaining the proposed
clarification in paragraph (b) of this NWP, with respect to the NWP
authorizing work in non-tidal navigable waters of the United States
(i.e., section 10 waters). The clarification regarding work in section
10 waters was added because the Corps' definition of ``work'' at 33 CFR
322.2(c) for the purposes of Section 10 of the Rivers and Harbors Act
of 1899 includes ``without limitation, any dredging or disposal of
dredged material, excavation, filling, or other modification of a
navigable water of the United States.''
One commenter said that this NWP should not authorize activities in
waters inhabited by salmon. A few commenters stated that the Corps must
consider the numerous proposals for sulfide-ore copper mining in
Minnesota and Wisconsin in light of unique lake-land system that is
highly susceptible to mining caused pollution and degradation.
All activities authorized by this NWP require pre-construction
notification. District engineers will review PCNs for proposed
activities and determine whether they may affect ESA-listed species or
designated critical habitat. If the district engineer determines a
proposed NWP 44 activity may affect listed species or designated
critical habitat, he or she will conduct ESA section 7 consultation
with the U.S. FWS or NMFS as appropriate. Proposals for mining
activities in Minnesota and Wisconsin are evaluated by the Corps' St.
Paul District.
This NWP is reissued as proposed.
(9) NWP 48. Commercial Shellfish Mariculture Activities
The Corps proposed a number of modifications to this NWP. The Corps
proposed to change the title of this NWP from ``Commercial Shellfish
Aquaculture Activities'' to ``Commercial Shellfish Mariculture
Activities'' to more accurately reflect where these activities are
conducted (i.e., coastal waters). The Corps also proposed to remove the
\1/2\-acre limit for new activities that have direct effects on
submerged aquatic vegetation in project areas that that have not been
used for commercial shellfish aquaculture activities during the past
100 years. In addition to the proposed removal of that \1/2\-acre
limit, the Corps proposed to remove the definition of ``new commercial
shellfish aquaculture operation'' that was adopted in 2017. Also, the
Corps proposed to remove both PCN thresholds for this NWP, as well as
the paragraph that identifies the additional information that
permittees must submit with their NWP 48 PCNs.
[[Page 2788]]
The Corps changed the title of this NWP to ``Commercial Shellfish
Mariculture Activities'' because the NWP only authorizes activities in
coastal waters. Mariculture is the cultivation of organisms in marine
and estuarine open water environments (NRC 2010). The term
``aquaculture'' refers to a broad spectrum of production of aquatic
organisms. In the United States aquaculture activities encompass the
production of marine and freshwater finfish, as well as shellfish
(bivalve molluscs and crustaceans). Oysters, clams, mussels, and
scallops are examples of bivalve molluscs (bivalves). Since aquaculture
activities in the United States include both water-based and land-based
activities, we use the term ``mariculture'' in NWPs 48, 55 (seaweed
mariculture activities), and 56 (finfish mariculture activities) to
make it clear that these NWPs only authorize activities in marine and
estuarine waters.
In response to the October 10, 2019 decision of the United States
District Court, Western District of Washington at Seattle in the
Coalition to Protect Puget Sound Habitat v. U.S. Army Corps of
Engineers et al. (Case No. C16-0950RSL) and Center for Food Safety v.
U.S. Army Corps of Engineers et al. (Case No. C17-1209RSL), the Corps
has made substantial revisions to the national decision document for
NWP 48. The revisions addressed, to the extent appropriate, issues
identified in the district court's decision. A copy of the final
national decision document is available in the docket at
www.regulations.gov (COE-2020-0002).
The national decision document for the 2021 NWP 48 provides a more
thorough discussion of the direct and indirect impacts caused by
commercial shellfish mariculture activities. The national decision
document also uses a broader set of scientific literature to support
that discussion of potential effects to various resources and the human
environment. The national decision document does not focus solely on
oyster mariculture; rather, it also discusses mariculture activities
for other bivalve species, such as clams, mussels, and scallops. The
national decision document presents a more detailed discussion of the
potential impacts of commercial shellfish mariculture activities on
aquatic vegetation other than seagrasses, benthic communities, fish,
birds, water quality, and substrate characteristics.
The national decision document provides a more thorough discussion
of how the Corps applies its two permitting authorities to commercial
shellfish mariculture activities (i.e., Section 10 of the Rivers and
Harbors Act of 1899 and Section 404 of the Clean Water Act). It
discusses the types of activities regulated under those authorities and
their potential environmental consequences. In addition, the national
decision document provides a more rigorous analysis to support a
finding, at a national level, that the NWP would authorize only those
commercial shellfish mariculture activities that have no more than
minimal individual and cumulative adverse environmental effects. The
national decision document explains that division engineers retain the
authority to modify, suspend, or revoke NWP 48 on a regional basis (see
33 CFR 330.5(c)). It further discusses the authority of district
engineers to modify, suspend, or revoke NWP 48 on a case-by-case basis
(see 33 CFR 330.5(d)) if impacts of an activity proposed for
authorization using NWP 48 has more than a minimal adverse effect on
the environment. A copy of the national decision document for the 2021
NWP 48 is available in the www.regulations.gov docket for this
rulemaking action (docket number COE-2020-0002).
Commercial shellfish mariculture activities involve the production
of bivalves such as oysters, mussels, clams, and scallops. These
activities occur in marine and estuarine coastal waters of the United
States. As discussed above, the Corps regulates commercial shellfish
mariculture activities under two of its permitting authorities: Section
10 of the Rivers and Harbors Act of 1899 and Section 404 of the Clean
Water Act. Under Section 10 of the Rivers and Harbors Act of 1899, the
Corps regulates structures and work in navigable waters of the United
States. Under Section 404 of the Clean Water Act, the Corps regulates
discharges of dredged or fill material into waters of the United
States.
Nationwide permit 48 authorizes structures or work in navigable
waters of the United States for commercial shellfish mariculture
activities when DA permits are required by Section 10 the Rivers and
Harbors Act of 1899. The Corps' regulations for Section 10 of the
Rivers and Harbors Act of 1899 in 33 CFR part 322 define the term
``structure'' as including, ``without limitation, any pier, boat dock,
boat ramp, wharf, dolphin, weir, boom, breakwater, bulkhead, revetment,
riprap, jetty, artificial island, artificial reef, permanent mooring
structure, power transmission line, permanently moored floating vessel,
piling, aid to navigation, or any other obstacle or obstruction.'' [33
CFR 322.2(b)] Commercial shellfish mariculture activities usually
involve structures such as cages, racks, nets, pilings, lines, trays,
tubes, ropes, and bouchots (i.e., piles wrapped in rope for cultivating
mussels) placed in navigable waters to cultivate bivalves.
Oysters may be cultivated using structures such as cages, trays,
racks, bags, and lines. Oyster mariculture may be conducted through on-
bottom or off-bottom techniques (NRC 2010). Clams are generally
cultivated through on-bottom techniques because the commercially
produced species are infaunal organisms that grow in the substrate of
waterbodies (NRC 2010). Clam mariculture may involve the use of
structures such as tubes and anti-predator netting. Mussels may be
cultivated by attaching mussel brood stock or seed to ropes, which are
suspended in the water column from a floating raft. Mussels may also be
grown on ropes attached to pilings (bouchots) (McKindsey et al. 2011),
or in cages, trays, or racks. Mussels may also be cultivated through
on-bottom or off-bottom culture methods (NRC 2010). For example,
mussels may be grown on ropes suspended in the water column from a
raft, or via bottom culture. Scallops may be attached to ropes via
monofilament lines tied through a small hole drilled into the shell
(Robinson et al. 2016), a technique called ``ear hanging.''
The installation and use of structures such as racks, cages, bags,
lines, nets, and tubes, in navigable waters for commercial bivalve
shellfish mariculture activities in navigable waters requires DA
authorization under Section 10 of the Rivers and Harbors Act of 1899.
Department of the Army authorization is required under Section 10 of
the Rivers and Harbors Act of 1899 for all structures and/or work in or
affecting navigable waters of the United States, except for activities
identified in section 322.4 of the Corps' section 10 regulations (see
33 CFR 322.3). The exceptions in section 322.4 are limited to: (a)
Activities that were commenced or completed shoreward of established
federal harbor lines before May 27, 1970; and (b) wharves and piers
construct in any waterbody, located entirely within one state where the
waterbody is a navigable water of the United States solely on the basis
of its historical use to transport interstate commerce. None of these
exceptions apply to structures or work for commercial shellfish
mariculture activities. In the Corps' section 10 regulations, there is
no de minimis exception from the requirement to obtain DA authorization
for structures and work in navigable waters of the
[[Page 2789]]
United States. Any structure or work that alters or obstructs navigable
waters of the United States requires section 10 authorization from the
Corps. With respect to structures used for shellfish mariculture
activities, those structures require section 10 authorization because
they alter navigable waters of the United States even though there
might be circumstances where they might not obstruct navigation.
Commercial shellfish mariculture structures may be floating or
suspended in navigable waters, placed on the bottom of the waterbody,
or installed in the substrate of the waterbody. The placement of
mariculture structures in the water column or on the bottom of a
waterbody does not result in a discharge of dredged or fill material
that is regulated under section 404 of the Clean Water Act. While the
presence of these structures in a waterbody may alter water movement
and cause sediment to fall out of suspension onto the bottom of the
waterbody, that sediment deposition is not considered a discharge of
dredged or fill material because those sediments were not discharged
from a point source. In general, the placement of bivalve shellfish
mariculture structures on the bottom of a navigable waterbody, or into
the substrate of a navigable waterbody does not result in discharges of
dredged or fill material into waters of the United States that are
regulated under Section 404 of the Clean Water Act.
The Corps' section 10 regulations define the term ``work'' as
including, ``without limitation, any dredging or disposal of dredged
material, excavation, filling, or other modification of a navigable
water of the United States.'' [33 CFR 322.2(c)] Under this NWP, the
section 10 authorization applies to discharges of dredged or fill
material into waters of the United States that are also navigable
waters under Section 10 of the Rivers and Harbors Act of 1899.
Commercial shellfish mariculture activities often involve work that
requires authorization under Section 10 of the Rivers and Harbors Act,
such as harvesting and bed preparation activities. Bed preparation
activities may include tilling or harrowing activities, or the
placement of shell or gravel to provide substrate suitable for the
establishment and growth of bivalves via bottom culture.
Commercial shellfish mariculture activities that only require
authorization under Section 10 of the Rivers and Harbors Act of 1899
are evaluated under the Corps' public interest review process at 33 CFR
320.4. The Clean Water Act Section 404(b)(1) Guidelines issued by the
U.S. EPA do not apply to activities authorized by the Corps under its
section 10 authority because those guidelines only apply to activities
that require authorization under Section 404 of the Clean Water Act.
The 404(b)(1) Guidelines do not apply to section 10 activities that may
directly or indirectly impact special aquatic sites such as vegetated
shallows (i.e., submerged aquatic vegetation).
Section 101(a)(2) of the Clean Water Act states that ``it is the
national goal that wherever attainable, an interim goal of water
quality which provides for the protection and propagation of fish,
shellfish, and wildlife and provides for recreation in and on the water
be achieved by July 1, 1983.'' [33 U.S.C. 1251(a)(2)] In other words,
one of the goals of the Clean Water Act is to promote water quality
that supports the propagation of fish and shellfish, in addition to
other uses of waters of the United States.
The Clean Water Act regulates discharges of pollutants into waters
of the United States. See 33 U.S.C. 1311(a). Section 502(6) of the
Clean Water Act defines the term ``pollutant'' as meaning ``dredged
spoil, solid waste, incinerator residue, sewage, garbage, sewage
sludge, munitions, chemical wastes, biological materials, radioactive
materials, heat, wrecked or discarded equipment, rock, sand, cellar
dirt and industrial, municipal, and agricultural waste discharged into
water.'' Section 502(12) of the Clean Water Act defines the terms
``discharge of a pollutant'' and ``discharge of pollutants'' as
meaning: Any addition of any pollutant to navigable waters from any
point source, or any addition of any pollutant to the waters of the
contiguous zone or the ocean from any point source other than a vessel
or other floating craft.
Point source discharges of pollutants are regulated under Sections
402 and 404 of the Clean Water Act. Under Section 402 of the Clean
Water Act, the U.S. EPA authorized state agencies to regulate a variety
of pollutants that may be discharged into waters of the United States
via a point source. Under Section 404 of the Clean Water Act, the Corps
regulates discharges of dredged or fill material into waters of the
United States. Discharges of dredged or fill material into waters of
the United States that require section 404 permits must comply with the
Clean Water Act section 404(b)(1) Guidelines issued by the U.S. EPA at
40 CFR part 230.
The term ``pollutant'' does not include the placement of shellfish
seed or bivalves at various stages of growth into jurisdictional
waters, or the waste products (e.g., feces or pseudofeces, ammonium)
excreted by bivalves. In Association to Protect Hammersley, Eld, and
Totten Inlets v. Taylor Res., Inc., 299 F.3d 1007 (9th Cir. 2002), the
court concluded that Congress did not intend that living bivalves and
the natural chemicals and particulate biological matter they release
through normal physiological processes, or the shells that might be
separated from living bivalves from time to time, be considered
pollutants under the Clean Water Act. In other words, bivalve shells
and natural waste products excreted by living bivalves are not
``biological materials'' under the Clean Water Act's definition of
``pollutant'' because shells and natural waste products come from the
natural growth and development of bivalves and not from a
transformative human process.
The EPA's National Summary of State Information, water quality
assessment and total maximum daily load (TMDL) information,\3\ provides
information on the causes of impairment and probable sources of
impairment for the Nation's waters, including bays, estuaries, coastal
shorelines, ocean waters, and near coastal waters where commercial
shellfish mariculture activities may occur. Twenty-eight causes of
impairment were identified for bays and estuaries. The top 10 causes of
impairment for bays and estuaries are: Polychlorinated biphenyls,
nutrients, mercury, turbidity, dioxins, toxic organics, metals (other
than mercury), pesticides, pathogens, and organic enrichment/oxygen
depletion. For bays and estuaries, the top 10 sources of impairment for
bay and estuaries are: Legacy/historic pollutants, urban-related
runoff/stormwater, unknown sources, atmospheric deposition, municipal
discharges/sewage, unspecific non-point sources, other sources,
natural/wildlife, agriculture, and industrial.
---------------------------------------------------------------------------
\3\ https://iaspub.epa.gov/waters10/attains_nation_cy.control
(accessed November 27, 2020).
---------------------------------------------------------------------------
Coastal shorelines were impaired by 16 identified causes, the top
10 of which are: Mercury, pathogens, turbidity, organic enrichment/
oxygen depletion, pH/acidity/caustic conditions, nutrients, oil and
grease, temperature, cause unknown--impaired biota, and algal growth.
The top 10 sources of impairment of coastal shorelines are municipal
discharges/sewage, urban-related runoff/stormwater, ``unknown,''
recreational boating and marinas, hydromodification, industrial,
unspecified non-point source, agriculture, legacy/historic pollutants,
and land application/waste sites/tanks.
Ocean and near coastal waters were impaired by 17 identified
causes, the
[[Page 2790]]
top 10 of which are: Mercury, organic enrichment/oxygen depletion,
pathogens, metals (other than mercury), pesticides, turbidity, nuisance
exotic species, total toxics, pH/acidity/caustic conditions, and
polychlorinated biphenyls. The top 10 sources of impairment of ocean
and near coastal waters are: Atmospheric deposition, unknown sources,
unspecified non-point sources, other sources, recreation and tourism
(non-boating), recreational boating and marinas, urban-related runoff/
stormwater, hydromodification, municipal discharges/sewage, and
construction.
None of the top 10 sources of impairment of these categories of
waters are directly related to commercial shellfish mariculture
activities. Commercial shellfish mariculture activities require clean
water to produce bivalve shellfish for human consumption. Further, the
ability of bivalves to improve water quality is well understood and
their presence in an aquatic ecosystem is considered to be beneficial
(e.g., NRC 2010).
Mariculture activities can be classified as extensive or intensive.
For extensive mariculture, young organisms are allowed to grow
naturally using resources (food, inorganic nutrients) available in
marine and estuarine waters until they are harvested (Diana et al.
2009). In intensive mariculture, the young organisms are provided feed
to promote their growth before they are harvested. Bivalve shellfish
mariculture and seaweed mariculture are examples of extensive
mariculture, and for such activities there is no addition of materials
(e.g., nutrients) through a point source that might trigger a permit
requirement. However, in some cases a pesticide might be applied in
waters where bivalve shellfish mariculture occurs (NRC 2010, Simenstad
and Fresh 1995). The application of pesticides is not regulated by the
Corps under Section 404 of the Clean Water Act, but it may be regulated
by EPA or approved states under Section 402 of the Clean Water Act. As
discussed in the previous paragraph, the bivalves themselves that are
seeded in the waterbody, or are added to the waterbody after a limited
grow out period in a nursery facility located on-shore or elsewhere,
does not trigger a permit requirement the Clean Water Act because those
living organisms are not considered to be pollutants under the Act.
Nationwide permit 48 also authorizes discharges of dredged or fill
material into waters of the United States. The Corps' regulations
define ``dredged material'' as ``material that is excavated or dredged
from waters of the United States.'' [33 CFR 323.2(c)] The term
``discharge of dredged material'' is defined at 33 CFR 323.2(d)(1) as
meaning ``any addition of dredged material into, including redeposit of
dredged material other than incidental fallback within, the waters of
the United States.'' The term ``discharge of dredged material''
includes, but is not limited to: (1) The addition of dredged material
to a specified discharge site located in waters of the United States;
(2) the runoff or overflow from a contained land or water disposal
area; and (3) any addition, including redeposit other than incidental
fallback, of dredged material, including excavated material, into
waters of the United States which is incidental to any activity,
including mechanized landclearing, ditching, channelization, or other
excavation. [33 CFR 323.2(d)(1)] Some activities associated with
commercial shellfish mariculture may result in a discharge of dredged
material under the third instance identified above (i.e., redeposit of
dredged material other than incidental fallback).
Some commercial shellfish mariculture activities involve mechanical
or hydraulic harvesting techniques that may or may not result in
discharges of dredged material that require authorization under Section
404 of the Clean Water Act. If the bivalve harvesting activity would
result in only incidental fallback of dredged material into the
waterbody, a section 404 permit would not be required. (However, a
section 10 permit would be required as ``work'' in navigable waters). A
section 404 permit would be required for a mechanical or hydraulic
harvesting activity if that activity results in a regulated discharge
of dredged material by having more than incidental fallback. Some
harvesting activities associated with commercial shellfish mariculture
operations may result in the redeposit of dredged material other than
incidental fallback within the waters of the United States. For
example, dredge harvesting activities may remove sediment along with
the bivalves. If the removed sediment is deposited back into the
waterbody in a different location, and is more than incidental
fallback, then the harvesting activity may be determined by the
district engineer to result in a discharge of dredged material that
requires section 404 authorization. On the other hand, if the sediment
removed while harvesting the bivalves is redeposited in the same
location, then it may be considered to be incidental fallback, and not
require section 404 authorization.
The Corps' regulations at 33 CFR 323.2(e)(1) define ``fill
material'' as meaning ``material placed in waters of the United States
where the material has the effect of: (1) Replacing any portion of a
water of the United States with dry land; or (2) changing the bottom
elevation of any portion of a water of the United States. Examples of
fill material include: ``rock, sand, soil, clay, plastics, construction
debris, wood chips, overburden from mining or other excavation
activities, and materials used to create any structure or
infrastructure in the waters of the United States.'' [33 CFR
323.2(e)(2)] ``Fill material'' does not include trash or garbage (see
33 CFR 323.2(e)(3)). Discharges of trash or garbage may be regulated
under other federal, state, or local laws and regulations. Fill
material does not include the placement or release of living organisms,
such as bivalve larvae and juvenile bivalves, into waters of the United
States.
The term ``shellfish seeding'' is defined in Section E of the NWPs
as the ``placement of shellfish seed and/or suitable substrate to
increase shellfish production. Bivalve shellfish seed consists of
immature individual shellfish or individual shellfish attached to
shells or shell fragments (i.e., spat on shell). Suitable substrate may
consist of shellfish shells, shell fragments, or other appropriate
materials placed into waters for shellfish habitat.'' This definition
was adopted in the NWPs in 2007 (see 72 FR 11197). Other materials may
be used for bivalve shellfish seeding such as nets, bags, and ropes.
Shellfish seed can be produced in a hatchery. Shellfish seed can also
be produced in waterbodies where bivalve larvae can attach to
appropriate materials, such as shell pieces, bags, or ropes.
Placing shellfish seed on the bottom of a waterbody is not a
``discharge of fill material'' and thus does not require a section 404
permit. Placing gravel or shell on the bottom of a waterbody to provide
suitable substrate for bivalve larvae to attach to is considered to be
a ``discharge of fill material'' and would require section 404
authorization. The shellfish themselves, either growing on the bottom
of a waterbody or in nets, bags, or on ropes, are not considered to be
``fill material'' and do not require a section 404 permit to be
emplaced, remain in place, or to be removed from a waterbody.
On-bottom bivalve shellfish mariculture activities may involve
placing fill material such as shell or gravel to provide suitable
substrate for bivalve larvae to attach to and grow on the bottom of the
waterbody. These fill activities may require section 404 authorization.
The placement of structures that are used for commercial
[[Page 2791]]
shellfish mariculture activities, such as cages, bags, racks, tubes,
and netting, does not result in discharges of dredged or fill material
into waters of the United States and therefore do not require
authorization under Section 404 of the Clean Water Act. As discussed
above, the placement of cages, bags, racks, tubes, lines, and netting
and other structures in navigable waters of the United States for the
purposes of commercial shellfish mariculture activities is regulated
under Section 10 of the Rivers and Harbors Act of 1899 because they can
be potential obstructions to navigation.
In the 2020 Proposal, the Corps proposed to remove the \1/2\-acre
limit for new commercial shellfish mariculture activities that directly
affect submerged aquatic vegetation. The Corps also proposed to remove
the definition of ``new commercial shellfish mariculture activities.''
Many commenters said that the \1/2\-acre limit for direct impacts
to submerged aquatic vegetation for new commercial shellfish
mariculture activities should be retained because removal of the \1/2\-
acre could cause significant and permanent losses of submerged aquatic
vegetation. One commenter said that allowing new commercial shellfish
mariculture activities to directly affect more than \1/2\-acre of
submerged aquatic vegetation would result in more than minimal adverse
environmental effects. A couple of commenters stated that the removal
of the \1/2\-acre limit for impacts to submerged aquatic vegetation
conflicts with submerged aquatic vegetation goals and restoration
efforts in different states. These commenters said that many federal,
state, and local agencies are working throughout the country to recover
lost submerged aquatic vegetation habitat in support of water quality
and ecosystem goals. Removal of the \1/2\-acre limit would undermine
the investments and progress made to date to recover these important
habitats.
The Corps is removing the \1/2\-acre limit for new commercial
shellfish mariculture activities that directly affect submerged aquatic
vegetation in the project area. In place of the \1/2\-acre limit, the
Corps is substituting a PCN requirement for new and existing commercial
shellfish mariculture activities that directly affect more than \1/2\-
acre of submerged aquatic vegetation. This new PCN requirement
accompanies the removal of the definition of ``new commercial shellfish
aquaculture operation'' and will provide activity-specific review of
all commercial shellfish mariculture activities that directly affect
more than \1/2\-acre of submerged aquatic vegetation. In response to a
PCN, the district engineer can add conditions to the NWP authorization
to require mitigation, such as best management practices or other
mitigation measures, to ensure that the individual and cumulative
adverse environmental effects are no more than minimal.
Under the 2017 NWP 48, the \1/2\-acre limit only applied to new
commercial shellfish mariculture activities. After a new commercial
shellfish mariculture activities was authorized by the Corps, the \1/
2\-acre limit no longer applied to the existing commercial shellfish
mariculture activity. In this regard, it was less protective than the
NWP 48 in this final rule, which would apply a PCN requirement to
existing operations seeking reauthorization. The removal of the \1/2\-
acre limit in this final rule does not affect the authority of other
federal agencies or tribal, state, or local governments to adopt and
implement protection programs for submerged aquatic vegetation under
their authorities.
Submerged aquatic vegetation does not have any special status under
the Corps' regulations for implementing Section 10 of the Rivers and
Harbors Act of 1899, which is the statute that applies to most
commercial shellfish mariculture activities. Submerged aquatic
vegetation is covered by a number of the Corps' public interest review
factors such as conservation, general environmental conditions, fish
and wildlife values, and wetlands. While vegetated shallows are special
aquatic sites under the Clean Water Act Section 404(b)(1) Guidelines,
the Guidelines do not prohibit discharges of dredged or fill material
into vegetated shallows. A smaller proportion of commercial shellfish
mariculture activities trigger the permit requirements of Section 404
of the Clean Water Act because many commercial shellfish mariculture
activities do not involve discharges of dredged or fill material into
waters of the United States. Impacts to submerged aquatic vegetation
caused by commercial shellfish mariculture activities may also be
addressed through Endangered Species Act Section 7 consultations for
proposed NWP 48 activities that district engineers determine ``may
affect'' listed species or designated critical habitat, including
critical habitat for which submerged aquatic vegetation is a physical
or biological feature. Impacts to submerged aquatic vegetation may also
be addressed through the essential fish habitat consultation process
when the district engineer determines a proposed NWP 48 activity may
adversely affect essential fish habitat, which may include submerged
aquatic vegetation beds.
Several commenters recommended that the Corps propose a revised
threshold for seagrass impacts based on biological reference points.
These commenters said that this is particularly important in regions
where additional provisions to protect seagrasses are not in place and
state laws do not impose additional restrictions on eelgrass. One
commenter stated that the Corps seeks to remove an impact limitation
that would otherwise incentivize responsible siting of mariculture
operations and minimization of impacts to submerged aquatic vegetation.
The Corps declines to impose an additional threshold for seagrass
impacts based on biological reference points because it would be
impractical to establish such biological reference points at a national
level for activities requiring authorization under section 10 of the
Rivers and Harbors Act of 1899 and section 404 of the Clean Water Act.
The threshold to require a PCN for new and existing commercial
mariculture operations that impact more than \1/2\-acre of submerged
aquatic vegetation is sufficient for the purposes of ensuring that a
project will have no more than a minimal individual or cumulative
adverse environmental impact. If a state decides not to take measures
to regulate activities in submerged aquatic vegetation within its own
waters, it does not create a legal or regulatory requirement for the
Corps to address such situations. The requirements of NWP 48 will
continue to provide incentives for commercial shellfish mariculture
operators to plan and design their activities to qualify for NWP
authorization. As discussed above there are other applicable laws that
can address impacts to submerged aquatic vegetation in conjunction with
the Corps' NWP authorization. In addition, where necessary based on the
characteristics of the regional ecosystem, division engineers can add
regional conditions to NWP 48 to help ensure that activities authorized
by this NWP result in no more than minimal individual and cumulative
adverse environmental effects.
Several commenters supported removing the 2017 definition of ``new
operation'' as it is not relevant to a specific date or timeline. One
commenter stated that the Corps has not been able to justify why one
set of rules should apply to existing commercial shellfish mariculture
operators and another set of rules should apply to everyone else,
including new commercial shellfish mariculture
[[Page 2792]]
operators. This commenter said that if there is a conservation
justification for protecting eelgrass and other submerged aquatic
vegetation, then limitations on impacts to submerged aquatic vegetation
should apply to everyone. One commenter said that removal of this
definition failed to identify what it would be replaced with and stated
that there needs a definition for new commercial shellfish mariculture
activities but it must not conflict with tribal treaty reserved rights
to take shellfish.
The Corps has removed the definition of ``new commercial shellfish
aquaculture operation'' from this NWP. The new \1/2\-acre PCN threshold
will apply to both new and existing commercial shellfish mariculture
activities. All activities authorized by NWP 48 must comply with
general condition 17, tribal rights.
One commenter said that the removing the distinction for new
operations, with the \1/2\-acre limit, will result in more impacts.
This commenter asserted that the Corps does little to justify the
proposed removal of the \1/2\-acre limit, given that it added this
limit three years ago to ensure impacts from NWP 48 would be no more
than minimal. One commenter recommended adding the following definition
for an ongoing or existing activity: Existing commercial shellfish
aquaculture should be defined as the area under cultivation when NWP 48
was first issued in 2007 or where an operator can document that an area
is part of a regular rotation of cultivation.
The \1/2\-acre limit for new commercial shellfish mariculture
activities was added to NWP 48 in 2012 (see 77 FR 10280). The \1/2\-
acre limit only applied to new commercial shellfish activities, and
does not apply when those on-going activities are authorized when NWP
48 is reissued after the current NWP expires. There is no need to add a
definition of on-going commercial shellfish mariculture activities,
because both new and existing activities are treated the same under
this reissued NWP.
One commenter stated that the Corps should identify a clear spatial
delineation of what constitutes a waterbody to aid in decision-making
and allow the public to determine the scope of this action. One
commenter noted that the provision for ``project area'' could be
subject to two differing interpretations. First, it could refer to that
area where some entity or agreement specifically authorizes the
operator to conduct commercial shellfish aquaculture. Second, it could
be read as being that area where a legally binding agreement
establishes an enforceable property interest for the operator. This
commenter recommended revising the term ``project area'' to read as
follows: ``The project area is an area in which the operator conducts
commercial shellfish aquaculture activities, as authorized by a lease
or permit or other legally binding agreement.''
The geographic scope for an NWP 48 activity is the project area,
and the term project area is defined in the text of the NWP. The Corps
did not change the definition of project area, and it covers both
situations identified by the commenter. It is not necessary to and the
Corps declines to define, at a national level, what constitutes a
waterbody for the purposes of NWP 48. District engineers can identify
the geographic extent of waterbodies for the purposes of NWP 48
activities.
In the 2020 Proposal, the Corps proposed to remove the pre-
construction notification thresholds for this NWP because most of the
direct and indirect impacts caused by the activities authorized by this
NWP under its permitting authorities (i.e., Section 10 of the Rivers
and Harbors Act of 1899 and, when applicable, Section of the Clean
Water Act) are temporary impacts. As discussed in the proposed rule,
NWP 48 activities may require PCNs because of the requirements of
paragraph (c) of NWP general condition 18, endangered species. Under
paragraph (c) of general condition 18, pre-construction notification is
required for non-federal permittees when any listed species or
designated critical habitat might be affected by the proposed NWP
activity or is in the vicinity of the proposed NWP activity, or if the
proposed NWP activity is located in designated critical habitat. In
some areas of the country, commercial shellfish mariculture activities
are located in waters inhabited by listed species and designated
critical habitat. Division engineers may also add regional conditions
to this NWP to require PCNs for some or all proposed NWP 48 activities.
Several commenters expressed concern of the removal of the PCN
thresholds for new or existing shellfish mariculture activities. These
commenters said the removal of the PCN thresholds will result in fewer
chances to account for regional differences in submerged aquatic
vegetation communities and it will make tracking of individual and
cumulative environmental impacts more difficult. One commenter said
that the Corps should require PCNs for all shellfish cultivation
operations across the country and evaluate sediment enrichment at
individual cultivation sites.
After evaluating the comments received in response to the proposed
changes to the notification requirements of this NWP, the Corps
determined that pre-construction notification should be required for
proposed activities that directly affect more than \1/2\-acre of
submerged aquatic vegetation. The Corps has added a new PCN requirement
to NWP 48 to require pre-construction notification for all NWP 48
activities that directly affect more than \1/2\-acre of submerged
aquatic vegetation. The new PCN threshold will provide district
engineers the opportunity to review all new and existing commercial
shellfish mariculture activities that directly affect more than \1/2\-
acre of submerged aquatic vegetation. The Corps does not agree that
PCNs should be required for all shellfish mariculture activities
because of potential impacts caused by temporary suspension of sediment
during harvesting activities or discharges of dredged material that may
occur during dredge harvesting activities utilizing hydraulic dredging
equipment. The impacts caused by the suspended sediment or discharged
sediment are temporary because the sediment will settle to the bottom
of the waterbody after a period of time. That period of time may depend
on local currents and other factors but is generally understood to be
relatively short (Newell et al. 1998) and not ecologically relevant,
especially in shallow waters where wave actions frequently cause
sediment to be suspended in the water column.
Direct effects of commercial shellfish mariculture activities on
submerged aquatic vegetation include the placement of structures such
as racks, bags, and cages on the bottom of a waterbody inhabited by
submerged aquatic vegetation. Direct effects of commercial shellfish
mariculture activities also include harvesting activities, including
mechanical and hydraulic dredging and harvesting by hand. Shading of
submerged aquatic vegetation by off-bottom bivalve mariculture
structures, such as floating racks, bags, and cages, is an indirect
effect that would not trigger this PCN requirement. Changes in water
flows caused by the use of long lines for bivalve mariculture
cultivation, where slowed water flows cause sediment to fall out of
suspension and accumulate on the bottom of the waterbody is another
example of a potential indirect effect that would not trigger this PCN
requirement. These direct and indirect effects would be caused by
structures or
[[Page 2793]]
work regulated under Section 10 of the Rivers and Harbors Act of 1899.
Direct effects also include discharges of dredged or fill material
on the bottom of a waterbody inhabited by submerged aquatic vegetation
for on-bottom culture methods, such as the placement of shell or gravel
to provide substrate for the bivalves to attach to and grow. Discharges
of dredged or fill material into waters of the United States may
smother submerged aquatic vegetation, which is a direct effect of those
activities. During harvesting activities that include regulated
discharges of dredged or fill material, there are likely to be direct
effects to submerged aquatic vegetation if those activities occur in
seagrass beds. These direct effects would trigger the PCN requirement
if they directly affect more than \1/2\-acre of submerged aquatic
vegetation An example of an indirect effect that might be caused by a
discharge of dredged or fill material into waters of the United States
for commercial shellfish mariculture activities might be a turbidity
plume that reaches areas beyond the discharge site, as suspended
sediment is transported by water currents away from that discharge
site. This indirect effect would not trigger the PCN requirement.
This pre-construction notification requirement will provide
district engineers the opportunity to evaluate each proposed activity
that will directly affect more than \1/2\-acre of submerged aquatic
vegetation and determine whether that activity qualifies for NWP 48
authorization. In response to a pre-construction notification, the
district engineer may require mitigation (e.g., on-site avoidance and
minimization) to ensure that the authorized activity complies with the
no more than minimal adverse environmental effects requirement for the
NWPs (see paragraph (a) of NWP general condition 23, mitigation).
The Corps has removed the additional information requirements for
PCNs from the text of NWP 48 because the information requirements of
NWP general condition 32 cover the information needed for this new PCN
requirement. The information requirements for NWP PCNs are listed in
paragraph (b) of NWP general condition 32, pre-construction
notification. Paragraph (b)(5) of NWP general condition 32 requires the
PCN to include a delineation of wetlands, other special aquatic sites
(including vegetated shallows, or submerged aquatic vegetation), and
other waters.
One commenter supported the removal of the PCN requirements because
in many instances bivalve populations have been overharvested or in
some cases attacked by diseases or poor water quality. This commenter
said that regulation of these activities should not impede the ability
to reinvigorate these species and growing them for food production. One
commenter supported of removal of the PCN threshold for commercial
shellfish mariculture for activities that include a species that has
never been cultivated in the waterbody as long as the NWP continues to
prohibit the cultivation of a nonindigenous species unless that species
has been previously cultivated in the waterbody, and prohibit the
cultivation of an aquatic nuisance species as defined in the
Nonindigenous Aquatic Nuisance Prevention and Control Act of 1990. One
commenter said that state natural resource agencies should be notified
for NWP 48 activities that seek to stock a species that has never been
cultivated in a waterbody, and applicable state permits be obtained
before the NWP 48 authorization becomes effective for a particular
commercial shellfish mariculture activity.
The addition of the PCN requirement for commercial shellfish
mariculture activities that directly affect more than \1/2\-acre of
submerged aquatic vegetation should not pose impediments on food
production or efforts to reinvigorate these species in waters whether
they have been overharvested. The Corps has also removed the PCN
threshold for indigenous species that have never been cultivated in the
waterbody. While the Corps has removed the PCN threshold, it has
modified the NWP to prohibit the cultivation of a nonindigenous species
unless that species has been previously cultivated in the waterbody.
State natural resources agencies can reach out to Corps districts to
request coordination on proposals to cultivate indigenous species that
have never been cultivated in the waterbody.
Several commenters stated the PCN requirements should not be
removed because tribes require notice and collaboration with the Corps
in order to protect their treaty fishing rights. These commenters said
that even temporary impacts to eelgrass could result in consequences to
tribe's treaty-reserved fish populations and the habitat they rely on.
In addition, these commenters stated that removal of the PCN thresholds
poses significant problems to assuring protection of salmon, nearshore
habitat, and treaty shellfish gathering rights. One commenter
recommended adding a PCN requirement for all activities within the U.S.
v. Washington (Boldt) case area.
During the process for issuing and reissuing these NWPs, Corps
districts have been consulting and coordinating with tribes. Corps
districts and tribes can establish coordination procedures to help
ensure that NWP 48 activities comply with general condition 17, tribal
rights. Division engineers can also add regional conditions to this
NWP, where appropriate based on the characteristics of the regional
ecosystem, to ensure that the activities authorized by this NWP cause
no more than minimal adverse environmental effects to specific
resources, including tribal trust resources.
One commenter expressed support for the proposed reissuance of NWP
48. One commenter expressed support for the reissuance of NWP 48
because this NWP could significantly reduce the barriers to entry for
emerging mariculture industries, and reduce the timeframes and costs
associated with obtaining DA authorization for such activities. One
commenter said that the conditions in the text of NWP 48 and NWP A
should be consistent and preferably combined into one NWP for
cultivating shellfish and seaweeds. One commenter stated that small
businesses are supportive of the proposed changes to NWP 48, but
acknowledged that there may be unfavorable litigation outcomes if the
changes are finalized. However, these businesses are concerned that
small businesses nationwide could be subject to unfavorable litigation
outcomes where the environmental analysis and justification for this
rulemaking is not sound.
Nationwide permit 48 provides a streamlined authorization process
for commercial shellfish mariculture activities that result in no more
than minimal adverse environmental effects, and should help reduce
regulatory burdens for the mariculture industry. The text of NWPs 48
and A (now designated as NWP 55) has some similarities, as well as some
differences. Some of those differences are due to NWP 55 activities
potentially occurring in a broader range of waters, including deeper
coastal waters more distance from the shoreline and federal waters over
the outer continental shelf. Commercial shellfish mariculture
activities typically occur in coastal waters new the shoreline. The
national decision document for this NWP has been revised to address the
2019 decision of the United States District Court, Western District of
Washington at Seattle in the Coalition to Protect Puget Sound Habitat
v. U.S. Army Corps of Engineers et al. (Case No. C16-0950RSL) and
Center for Food Safety v. U.S. Army
[[Page 2794]]
Corps of Engineers et al. (Case No. C17-1209RSL),
Several commenters stated that the Corps should not reissue NWP 48,
and if the Corps decides to reissue NWP 48 it should improve its review
of PCNs and require documentation of compliance with specific design
and operational standards. A few commenters said that the Corps should
not reissue NWP 48 as proposed for the same reasons that NWP was found
by the United States District Court, Western District of Washington at
Seattle to be in non-compliance with National Environmental Policy Act
and the Clean Water Act. One commenter said that regional general
permits should be issued in Washington State, for specific water bodies
and for particular types of shellfish aquaculture.
Nationwide permit 48 authorizes a variety of commercial shellfish
mariculture activities under Section 10 of the Rivers and Harbors Act
of 1899 and Section 404 of the Clean Water Act, and a number of
different structures can be used to cultivate bivalve molluscs. Project
proponents are responsible for designing their projects and for those
activities that require pre-construction notification, district
engineers evaluate the direct, indirect, and cumulative adverse
environmental effects caused by the proposed NWP activity. In the
national decision document, the Corps has revised its NEPA analysis and
its Clean Water Act Section 404(b)(1) Guidelines analysis. Regional
general permits can be issued by district engineers to authorize these
activities. Regional general permits can be effective in addressing
regional approaches to commercial shellfish mariculture activities and
the potential adverse environmental effects those activities may cause.
One commenter noted that a lack of clarity in the proposed rule may
lead to permitting delays and uncertainty, both of which have negative
effects on small businesses. A couple commenters said that with regards
to shellfish mariculture there needs to be more support from all levels
of government to consider first and foremost a food production activity
now and in the future to address our seafood deficit and food security
for our nation. One commenter recommended that the Corps utilize
information in Endangered Species Act and essential fish habitat
consultation documents issued in Washington State to support the
reissuance of NWP and address environmental issues of concern under the
Clean Water Act, the Rivers and Harbors Act of 1899, and the National
Environmental Policy Act.
The reissued NWP 48 will provide a streamlined authorization
process for commercial shellfish mariculture activities that cause no
more than minimal individual and cumulative adverse environmental
effects. Commercial shellfish mariculture activities may also be
regulated by tribal, state, and local governments. The consultation
documents issued by the U.S. FWS and NMFS in Washington State are
applicable only to Washington State, and this NWP authorizes commercial
shellfish mariculture activities across the country.
One commenter observed that at the national level, Congress passed
the National Aquaculture Act of 1980 in response to findings that the
nation has potential for significant aquaculture growth, but that this
growth is inhibited by many scientific, economic, legal, and production
factors. In support of the proposed reissuance of NWP 48, one commenter
cited the National Shellfish Initiative's goal of increasing
populations of bivalve shellfish in our nation's coastal waters--
including oysters, clams, and mussels--through commercial production
and conservation activities. One commenter stated that the NWP 48
should require notification to the U.S. Coast Guard.
The reissuance of NWP 48 helps support the growth of the
aquaculture industry in the United States by reducing regulatory
burdens on growers and providing a streamlined authorization process
under Section 10 of the Rivers and Harbors Act of 1899 and Section 404
of the Clean Water Act. The activities authorized by this NWP will also
help increase the numbers of bivalves in the Nation's coastal waters,
and the ecological functions and services those bivalve molluscs
provide, especially in coast waters where bivalve shellfish populations
have significantly declined as a result of overharvesting. The project
proponent is responsible for securing any licenses or permits from the
U.S. Coast Guard, and complying with U.S. Coast Guard requirements that
may apply to structures used for commercial shellfish mariculture
activities.
Several commenters supported changing the name of NWP 48 from
``commercial shellfish aquaculture activities'' to ``commercial
shellfish mariculture activities.'' One commenter suggested adding
modifying terms to ``aquaculture'' such as ``marine,'' ``coastal
marine,'' or ``offshore'' to improve specificity and clarity. One
commenter suggested clarifying that the terms ``mariculture'' and
``aquaculture'' can be used interchangeably. A couple of commenters
objected to changing ``aquaculture'' to ``mariculture'' in the title
and text of NWP 48. They suggested using the term ``marine
aquaculture'' to more closely align with the terms used by industry.
One said that using the term ``mariculture'' may result in an
unintended consequence of confusing or invalidating local and regional
policy and regulations. One commenter stated the term ``commercial
shellfish aquaculture'' is not defined and recommended defining that
term in a manner that does not conflict with tribes' treaty-secured
rights to take shellfish. One commenter stated that term ``shellfish''
is not explicitly defined, and recommended adding a definition to
clarify whether that term includes lobsters and conches or only
bivalves.
The Corps is retaining the use of the term ``mariculture'' in this
NWP. Use of the term ``mariculture'' in NWP 48, as well as NWPs 55 and
56, will not invalidate any local or regional policies or regulations.
The use of the term mariculture is intended to provide clarity, to
ensure that project proponents do not attempt to use NWP 48 to
authorize the production of other species considered to be
``shellfish'' (e.g., shrimp, crawfish) in land-based facilities and
ponds. The term ``mariculture'' refers to the cultivation of species
for food production, and should not interfere with a tribe's taking of
shellfish from coastal waters. The Corps has modified the first
paragraph of this NWP to clarify that the term ``shellfish'' refers to
bivalve molluscs such as oysters, clams, mussels, and scallops.
Several commenters said that the Corps' proposal fails to properly
consider that the impacts authorized by NWP 48 violate the Clean Water
Act and the Endangered Species Act. These commenters stated that the
impacts of commercial shellfish mariculture activities should be
evaluated through environmental impact statements and through formal
programmatic ESA consultations. One commenter stated that the Corps has
failed to provide adequate documentary support or substantive evidence
for its conclusions that permit terms and conditions would be
sufficient to ensure that environmental effects would be minimal and
not significant. One commenter asserted that the proposed NWP 48
violates the Section 404(e) of the Clean Water Act because it allows
unlimited impacts.
Activities authorized by NWP 48 must comply with general condition
18, endangered species. Some Corps districts have developed
programmatic ESA section 7 consultations that cover commercial
shellfish mariculture
[[Page 2795]]
activities. Activities authorized by NWP 48 do not require additional
NEPA compliance, since the Corps fulfills the requirements of NEPA when
it issues its national decision document for the reissuance of that
NWP, because that decision document includes and environmental
assessment with a finding of no significant impact. Section 404(e) of
the Clean Water Act does not require NWPs to have quantified acreage or
other limits to ensure that authorized activities result in no more
than minimal individual and cumulative adverse effects. Commenters have
not provided any substantive evidence to support their opinions that
all activities authorized by NWP 48 result in more than minimal adverse
environmental effects and should not be authorized by an NWP. The Corps
has issued a number of NWPs that do not have quantitative limits, such
as NWP 27 (Aquatic Habitat Restoration, Enhancement, and Establishment
Activities), NWP 31 (Maintenance of Existing Flood Control Facilities),
and NWP 38 (Cleanup of Hazardous and Toxic Waste).
Several commenters said that NWP 48 activities contribute to
degradation of waters of the United States by adversely affecting water
quality, eelgrass, salmon, birds, herring, and flatfish and causing
adverse effects from the introduction of plastics. One commenter
recommended prohibiting commercial shellfish mariculture activities in
or near marine protected areas or sensitive areas, such as essential
fish habitat. This commenter said that the NWP should prohibit the use
of plastic equipment or inputs such as pesticides, herbicides, or
pharmaceuticals. This commenter also said that NWP 48 activities should
require extensive documentation of compliance with design and operation
standards, with routine reporting. In addition, this commenter stated
that permitted activities should incorporate more rigorous operation,
emergency response, and pollution standards, with swift and severe
consequences for non-compliance, including revocation of permits.
The potential environmental effects caused by commercial shellfish
mariculture activities are discussed in the national decision document
for NWP 48. The Corps acknowledges that commercial shellfish
mariculture activities may have negative, positive, and neutral effects
on various environmental components, including various species. It is
generally understood that the presence of bivalves in an aquatic
ecosystem is beneficial. Some commenters point out various adverse
environmental effects caused by commercial shellfish mariculture
activities, but other acknowledge the studies and observations that
identify beneficial environmental effects caused by commercial
shellfish mariculture activities. If a proposed commercial shellfish
mariculture activity may adversely affect essential fish habitat as a
result of activity subject to the Corps' legal authority, the district
engineer will conduct essential fish habitat consultation with the
NMFS, and incorporate as appropriate, essential fish habitat
conservation recommendations into the NWP authorization as permit
conditions.
The Corps does not have the legal authority to regulate the use of
pesticides, herbicides, or pharmaceuticals that may be associated with
commercial shellfish mariculture activities. General condition 6
requires the use of suitable material for activities authorized by
NWPs. Plastics materials may be used for commercial shellfish
mariculture activities and it is the responsibility of the permittee to
ensure that structures that may be made with plastics (e.g., tubes for
geoducks, anti-predator netting) are properly maintained (see general
condition 14). The Corps has no authority to regulate plastics that may
wash away from a commercial shellfish mariculture activity. The Corps
does not regulate the placement of trash or garbage into waters of the
United States (see 33 CFR 323.2(e)(3)). Section 13 of the Rivers and
Harbors Act of 1899 (i.e., the Refuse Act) has been superseded by
Section 402 of the Clean Water Act (see 33 CFR 320.2(d)).
One commenter requested that the Corps change NWP 48 to remove any
unintended competitive edge for wild harvest fisheries, both in terms
of allowable gear and harvesting requirements. One commenter stated
that they investigated direct and indirect effects of individual bottom
cages on eelgrass, and found that at the current level of mariculture
activity, short-term cultivation of oysters has a minimal effect on
eelgrass growth, water quality, and sediment characteristics. However,
if the cultivation activity expands in terms of gear and/or individual
operations, it may result in measurable effects.
The Corps lacks the authority to prevent competition between
commercial shellfish mariculture operators and fishers that harvest
wild populations of bivalves. The Corps appreciates the information
regarding the direct and indirect effects of bottom cages for oyster
mariculture on eelgrass. The Corps is finalizing a new PCN threshold
for commercial shellfish mariculture activities directly affecting more
than \1/2\-acre of submerged aquatic vegetation to ensure the effects
noted by the commenter are evaluated by district engineers.
One commenter said that commercial shellfish mariculture activities
have minimal adverse impacts, and they can have beneficial effects on
habitat and water quality, and there is an extensive scientific
literature that supports the identification of these benefits. This
commenter discussed the structured habitat provided by commercial
shellfish mariculture activities that is used by numerous species for
refuge, foraging, and predator avoidance, thereby increasing species
richness, abundance, and biodiversity. This commenter also said that
bivalves ingest and filter suspended materials in the water column,
sequestering excess nutrients as protein in their tissue. This
commenter also remarked that upon harvesting these bivalve molluscs,
nutrients are removed from the marine ecosystem, which improves water
quality. This commenter also noted that commercial shellfish
mariculture activities can also help to transfer the load of suspended
materials from the water column to the benthos through a phenomenon
known as benthic-pelagic coupling. In addition, this commenter said
that by providing structured habitat, improving water quality, and
helping to transfer the load of suspended materials from the water
column to the benthos, shellfish can help mitigate adverse impacts
caused by several different types of human activities and developments.
This commenter stated that for these reasons, shellfish are
increasingly being utilized in environmental restoration projects
across the United States. The Corps acknowledges these comments on the
beneficial effects of commercial shellfish mariculture activities on
coastal waters. These beneficial effects have informed the Corps'
decision to reissue NWP 48 as discussed because it will have no more
than a minimal individual or cumulative adverse environmental effects.
One commenter said that impacts from geoduck farms are
insignificant (no more than minimal) for: Forage fish spawning areas;
consumption of forage fish larvae; juvenile salmon; waves, currents,
and sediment transport; microplastics; marine debris; impact to the
benthic community; cumulative impacts; recreation and navigation;
marine mammals; birds; farm preparation; predator protection netting;
harvest activities; density, genetics, diseases, and parasites; and
property values. This commenter remarked that
[[Page 2796]]
the disturbances caused by commercial shellfish mariculture activities
are within the range of natural variation experienced by benthic
communities in Puget Sound. This commenter also stated that differences
in the structure of mobile macrofauna communities between planted areas
with geoduck tubes and nets and nearby reference beaches do not persist
after the geoduck tubes and nets removed during the grow-out culture
phase. In addition, this commenter said that nutrients released from a
typical commercial geoduck operation are low and localized effects are
likely to be negligible. Finally, this commenter stated that geoduck
aquaculture practices do not make culture sites unsuitable for later
colonization by eelgrass. The Corps acknowledges these comments on the
beneficial effects of geoduck mariculture activities on coastal waters.
These beneficial effects have informed the Corps' decision to reissue
NWP 48 as discussed because it will have no more than a minimal
individual or cumulative adverse environmental effects.
One commenter said that commercial shellfish mariculture activities
have minimal impacts on birds, including foraging, noise, and the
potential for net entanglement. This commenter noted that birds forage
within mariculture operations, and feed on organisms growing on
mariculture equipment, and the shellfish being produced. This commenter
stated that noise associated with commercial shellfish mariculture
activities could result in temporary displacement of birds from the
immediate area, but this is a temporary impact to overall bird
populations. Lastly, this commenter asserted that while predator
exclusion net entanglement is a possibility for birds, it is likely to
be rare and unlikely to result in significant effects to marine bird
and bald eagle populations utilizing these areas. The Corps
acknowledges these comments on the effects of commercial shellfish
mariculture activities on birds, which have informed the Corps'
decision to reissue NWP 48 as discussed because it will have no more
than a minimal individual or cumulative adverse environmental effects.
One commenter objected to a statement in the proposed rule
regarding the placement of shell or gravel on the bottom of the
waterbody for on-bottom cultivation of bivalves. The proposed rule
stated that this is a permanent impact. This commenter said that the
placement of gravel or shell on the bottom of the waterbody causes
temporary changes, which is why shellfish farmers frequently need to
place gravel or shell in the same area from time to time. According to
this commenter, this temporary change has beneficial impacts to species
presence and diversity, according to a programmatic biological opinion
issued by the NMFS for commercial shellfish mariculture activities in
Washington State. This commenter said that placement of shell or gravel
on the bottom of the waterbody shifts the benthic community from
polychaetes to amphipods and copepods, which are important prey items
for juvenile salmon. This commenter requested that the Corps correct or
clarify this statement to recognize that the placement of shell or
gravel causes temporary, localized changes to the marine environment,
and these changes are beneficial.
If the commercial shellfish mariculture operator places shell or
gravel on the bottom of the waterbody, and does not remove the shell or
gravel, then it is a permanent impact. When an NWP authorizes a
temporary impact, the structure or fill has to be removed after that
structure or fill is no longer needed. For a temporarily filled area,
after the fill is removed several NWPs require the project proponent to
restore the affected area to pre-construction elevations. The Corps
acknowledges that a permanent fill may have positive, negative, or
neutral environmental effects. For example, the permanent fill may be
dispersed by flowing water and transported in the waterbody so that it
becomes part of the benthic habitat in that waterbody. That permanent
fill may provide habitat for certain aquatic organisms.
Several commenters said they agreed that placing shellfish seed on
the bottom of a waterbody is not a ``discharge of fill material'' and
thus does not require a section 404 permit. Regardless of that whether
the placement of shellfish seed is done for commercial aquaculture,
habitat restoration, or fisheries enhancement, it should not require a
section 404 permit unless there is significant placement of materials
for reefs/hummocks in quantities adequate to alter the depth profile
and alter the bottom topography. Several commenters noted that while
depositing shell with spat already attached is considered seed and
regulated ``work'' under Section 10 of the Rivers and Harbors Act of
1899, the proposed NWP 48 is also defining this as fill regulated under
Section 404 of the Clean Water Act. They stated that requiring section
404 authorization is an additional unnecessary burden and these
activities do not result in adverse environmental impacts and in
actuality have positive impacts to water quality. This method is unlike
a restoration project where oyster shell is deposited in large enough
quantities to create reefs and foster a permanent non-transient
population. This commenter requested that the Corps make a distinction
between two different activities: Sparsely placing shell on the bottom
of the waterbody to catch larvae and hummock building and restoration
efforts.
In the 2020 Proposal, the Corps did not state that shellfish
seeding activities require authorization under Section 404 of the Clean
Water Act. In addition, the Corps did not state that shellfish seeding
requires authorization under Section 10 of the Rivers and Harbors Act
of 1899. The placement of shell in a waterbody to construct reefs or
hummocks for bivalves to settle on and grow requires Clean Water Act
section 404 authorization because it raises the bottom elevation of the
waterbody and is a discharge of fill material, as that term is defined
at 33 CFR 323.2(e). That activity also requires authorization under
Section 10 of the Rivers and Harbors Act of 1899 as a structure (e.g.,
a reef) under 33 CFR 322.2(b) or work under 33 CFR 322.2(c).
One commenter said that placing single shellfish seeds on beds
without containment structures is not regulated under Section 10 of the
Rivers and Harbors Act of 1899. This commenter asserted that this
activity is not subject to regulation under section 10 because it does
not involve the use of structures, nor does it constitute work that
alters or modifies the navigable capacity of the waters. Juvenile clams
bury a few inches into the sediment and are essentially imperceptible,
and single-set oysters lie on the bottom of the substrate without
meaningfully altering the elevation of the seabed. This commenter said
that the placement and grow-out of single set clams and oysters
therefore does not require approval under Section 10 of the Rivers and
Harbors Act of 1899. This commenter noted that section 10 authorization
is required for activities that alter the bottom elevation of waters in
a manner to impact their navigable capacity, and that shellfish seeding
does not alter the bottom elevation.
In the proposed rule at 85 FR 57334, the Corps stated that on-
bottom bivalve shellfish mariculture activities may involve placing
fill material such as shell or gravel to provide suitable substrate for
bivalve shellfish larvae to attach to and grow on the bottom of the
waterbody and that these activities may require section 404
authorization. The proposed rule did not state that depositing shell
with spat attached to
[[Page 2797]]
the shell is considered fill material for the purposes of NWP 48.
Discharging shell without bivalve larvae (i.e., spat) into a waterbody
for the purposes of enhancing benthic habitat to attract bivalve
shellfish larvae may require section 404 authorization if it meets the
Corps' definition of ``fill material'' and ``discharge of fill
material'' at 33 CFR 323.2(e) and (f). Under 33 CFR 323.2(f), the term
``discharge of fill material'' means the addition of fill material into
waters of the United States. The term ``discharge of fill material''
does not include plowing, cultivating, seeding and harvesting for the
production of food, fiber, and forest products (33 CFR 323.2(f)), so
shellfish seeding is not considered a ``discharge of fill material.''
If the placement of gravel or shell on the bottom of the waterbody to
enhance the substrate of the waterbody to attract shellfish larvae is
not removed upon completion of the shellfish cultivation activity, it
is considered a permanent fill even though it may increase the habitat
value for bivalves, crustaceans, and other aquatic organisms.
A few commenters said that predator nets, and low-profile cages to
protect bottom planted seeds should not be considered navigation
hazards subject to permitting requirements unless they create a
vertical profile of greater than 25% of the water depth. One commenter
agreed with the Corps' statements in the proposed rule that most
commercial shellfish mariculture activities do not involve discharges
of dredged or fill material that require Clean Water Act section 404
authorization. This commenter noted that placing living bivalve
shellfish (e.g., clam seed and oyster cultch) in the intertidal zone
during bottom-culture activities and their natural by-products are not
pollutants, citing the Association to Protect Hammersley, Eld, and
Totten Inlets v. Taylor Res., Inc., 299 F.3d 1007 (9th Cir. 2002). One
commenter stated that the proposal accurately states that some
commercial bivalve shellfish mariculture activities are regulated under
section 10 because they include structures such as racks, cages, bags,
lines, nets, and tubes, when those structures are placed in navigable
waters. This commenter also said that dredging, excavation, and filling
activities would also require section 10 authorization, although these
activities are relatively rare.
The placement of predator nets and low-profile cages in navigable
waters of the United States requires authorization under Section 10 of
the Rivers and Harbors Act because those nets and cages are considered
structures under 33 CFR 322.2(b) and may be obstructions to navigation.
The Corps maintains its views that most commercial shellfish
mariculture activities are regulated solely under Section 10 of the
Rivers and Harbors Act of 1899, and a relatively small percentage are
also regulated under Section 404 of the Clean Water Act because they
involve discharges of dredged or fill material into waters of the
United States. The Corps agrees that the placement of living bivalves
into waters of the United States does not result in a discharge of a
pollutant that requires authorization under Section 404 of the Clean
Water Act.
One commenter said that bivalve shellfish harvesting activities do
not bring commercial shellfish farming within the regulatory reach of
Clean Water Act Section 404. In order for there to be a discharge
regulated under Section 404 of the Clean Water Act, there must be an
addition of a pollutant to a water of the United States, and that the
harvesting commercial shellfish does not involve an ``addition'' for
purposes of the Clean Water Act section 404. This commenter also stated
that harvesting shellfish constitutes a ``net withdrawal'' of material
from the water, not an ``addition.'' This commenter requested that the
Corps clarify in the final rule that these commercial shellfish farming
activities do not involve discharges of dredged or fill material and
hence do not require Clean Water Act Section 404 authorization.
The Corps does not agree that all bivalve shellfish harvesting
activities do not require authorization under Section 404 of the Clean
Water Act. There may be circumstances where a bivalve shellfish
harvesting activity results in a regulable discharge that requires
section 404 authorization. Those circumstances depend on how the
harvesting activity is conducted, and whether a particular harvesting
activity results in an addition of dredged material into, including
redeposit of dredged material other than incidental fallback within,
the waters of the United States. District engineers apply the
definitions of ``dredged material'' and ``discharge of dredged
material'' at 33 CFR 323.2(c) and (d), respectively to determine
whether a discharge requiring section 404 authorization has occurred.
The Corps agrees that bivalve shellfish harvesting activities do not
normally involve discharges of fill material, as that term is defined
at 33 CFR 323.2(f).
One commenter said that aquaculture is not exempt from CWA
permitting under Section 404(f) of the Clean Water Act. This commenter
said that adding gravel or shell to bags also triggers a section 404
permit requirement even if the bags themselves do not qualify as fill
material. Even for activities that do not directly result in discharge
of dredge or fill material, the Corps must document secondary effects,
and has the authority to impose conditions reasonably related to the
purpose of section 404 permits. Another commenter stated that
established shellfish farms are exempt from regulation under the Clean
Water Act's farming exemption, and that the reissued NWP 48 should
state that established commercial shellfish farming activities do not
require CWA Section 404 permits. This commenter said that even if some
shellfish farming activities include discharges of dredged or fill
material, established shellfish farms are exempt from regulation under
section 404(f), which exempts normal farming activities from the
requirement to obtain permits under Section 402 and 404 of the Act.
Whether shellfish mariculture qualifies for a section 404(f)
exemption is beyond the scope of this rulemaking. The authority for
determining whether a particular activity, such as commercial shellfish
mariculture activities, is eligible for the Clean Water Act Section
404(f) exemptions lies with the U.S. EPA. See the 1989 Memorandum of
Agreement Between the Department of the Army and the U.S. EPA
Concerning the Determination of the Section 404 Program and the
Application of the Exemptions under Section 404(f) of the Clean Water
Act.
One commenter stated that advanced authorization of the broad suite
of commercial shellfish mariculture activities afforded by the NWP 48
is impracticable because the blanket authorization cannot take into
account important details regarding local ecological conditions at the
growing site and specific information about the shellfish cultivation
techniques. This commenter recommended that initial authorization
should be made on a case-by-case basis and should be subject to ongoing
monitoring and periodic review.
Section 404(e) of the Clean Water Act does not specify how broadly
or narrowly the Corps has to identify any category of activities for
the issuance of a general permit, including the NWPs. Section 404(e)
only requires that the activities in that category are similar in
nature. Likewise, under the Corps' definition of general permit in its
section 10 regulations at 33 CFR 322.2(f), there are no standards
regarding how broad or narrow the category has to be. Therefore, the
Corps has substantial discretion to determine the categories of
activities to be
[[Page 2798]]
authorized by the NWPs. Nationwide permits are issued by Corps
Headquarters to authorize categories of activities across the country,
and there is substantial variation in aquatic resources and the
functions they provide, as well as the degree to which they perform
those functions. Nationwide permits require pre-construction
notification for certain activities so that district engineers can
assess proposed activities in the context of local ecological
conditions and make a case-by-case determination as to whether proposed
activities qualify for NWP authorization.
Some commenters mentioned that the scientific literature cited in
the proposed rule concerned studies of eelgrass located in Washington
State. These commenters stated that despite its broad distribution
along the Pacific and Atlantic coasts, eelgrass is a poor choice for a
model species to develop a national standard from a regional dataset.
One genus should not dictate policy on an entire suite of functionally,
taxonomically, and geographically distinct species. These commenters
went on to say that while the individual and cumulative impacts to
eelgrass meadows in Washington may be temporary, it could be
irreversible in areas where environmental conditions are more impaired
and submerged aquatic vegetation meadows are declining in areas such as
New England, the mid-Atlantic coast, the East coast of Florida, the
Gulf of Mexico, and California.
For the 2020 Proposal, the Corps considered scientific literature
in coastal ecosystems located nationwide. The Corps also discussed
submerged aquatic vegetation in general terms, and only made specific
references to eelgrass when a particular study examined eelgrass. After
the reissuance of NWP 48 in 2017, the Corps reviewed a broader range of
scientific literature on the interactions between commercial bivalve
shellfish mariculture activities and submerged aquatic vegetation, and
found that while some permanent impacts to submerged aquatic vegetation
may occur, the impacts are often temporary and submerged aquatic
vegetation co-exists with bivalve mariculture activities. The Corps
examined scientific literature from studies that occurred in other
areas of the United States (e.g., Chesapeake Bay), not just Washington
State.
One commenter recommended that the Corps require mitigation for
impacts to submerged aquatic vegetation at a ratio of at least 1.2:1
(mitigation area to impact area). One commenter said that when the
functional value of eelgrass and shellfish are combined, and the
seascape matrix of habitats are considered, it is possible that a
broader ecosystem perspective would find benefits from the presence of
aquaculture. This commenter also stated that commercial shellfish
farming activities have minimal negative to beneficial impacts on
eelgrass and supports the Corps' proposal to reissue NWP 48. One
commenter remarked that interactions between seagrasses and shellfish
mariculture must separately be addressed during Endangered Species Act
and Essential Fish Habitat consultations for authorizations for
shellfish farming activities in Washington State.
Compensatory mitigation requirements for activities authorized by
the NWPs are more appropriately determined by district engineers on a
case-by-case basis after reviewing PCNs. If the district engineer
reviews a PCN and determines the proposed activity will result in more
than minimal adverse environmental effects, he or she will notify the
applicant and provide an opportunity to the applicant to submit a
mitigation proposal (see 33 CFR 330.1(e)(3)). If, after reviewing the
mitigation proposal, the district engineer determines the adverse
environmental effects of the proposed activity will be no more than
minimal, she or he will issue an NWP verification with permit
conditions that require implementation of the mitigation. The Corps
acknowledges that, when viewed from a seascape perspective, a district
engineer may determine that the proposed shellfish mariculture will
provide ecological benefits that should be factored in the district
engineer's decision regarding whether the proposed activity will result
in no more than minimal adverse environmental effects. If the district
engineer reviews a PCN for a proposed NWP 48 activity and determines
the proposed activity may affect listed species or designated critical
habitat, he or she will conduct ESA section 7 consultation with the
U.S. FWS and/or NMFS and that section 7 consultation may address
potential impacts to seagrasses. If the district engineer reviews a PCN
for a proposed NWP 48 activity and determines the proposed activity may
adversely affect essential fish habitat, he or she will conduct
essential fish habitat consultation with the NMFS and the NMFS may
provide the district engineer with essential fish habitat conservation
recommendations that may address potential impacts to seagrasses.
Several commenters stated while shellfish mariculture can provide
ecosystem services, some of which are similar to seagrasses and other
benthic communities, there is no meaningful effort to discuss the
numerous studies regarding impacts of a variety of aquaculture
practices on submerged aquatic vegetation. Allowing commercial
shellfish activities in new areas that have extensive beds of submerged
aquatic vegetation could impact critical habitat for ESA-listed
species. A couple commenters stated that tribes in the Puget Sound
region have a unique interest in assuring that both salmon and
shellfish are allowed to flourish. Consultation between Corps
districts, tribes, federal, and state agencies are the appropriate
entities to determine how best to protect submerged aquatic vegetation.
A couple of commenters said that submerged aquatic vegetation is a
critical resource requiring protection and removal of that protection
from NWP 48 could create conflicts with other federal or state agencies
such as NOAA Fisheries. These commenters asserted that some states,
recognizing the need to protect these high-quality habitats have
prohibited the siting of new mariculture leases in areas where surveys
indicate the presence submerged aquatic vegetation in any one of the
past five years.
In the 2020 proposal and the draft decision document for NWP 48,
the Corps provided a substantial discussion of the positive and
negative impacts that commercial shellfish mariculture activities may
have on seagrasses and other benthic organisms. Some of these impacts
may be a result of activities under the Corps' legal authorities;
however, bivalve shellfish mariculture activities may have impacts that
are beyond the scope of the Corps' legal authorities. Under general
condition 18, non-federal permittees must submit a pre-construction
notification to the district engineer if any listed species or
designated critical habitat (or species proposed for listing) might be
affected or is in the vicinity of the activity, or if the activity is
located in designated or proposed critical habitat, and shall not begin
work on the activity until notified by the district engineer that the
requirements of the ESA have been satisfied and that the activity is
authorized (see paragraph (c) of general condition 18, endangered
species). During the rulemaking process, district engineers have
conducted consultation or coordination with tribes to identify regional
conditions or coordination procedures that could be used to protect
tribal trust resources and comply with general condition 17. Other
federal agencies, as well as states, can develop regulations and
policies to protect
[[Page 2799]]
submerged aquatic vegetation under their authorities.
A couple of commenters stated that the Corps thinks it is important
to protect submerged aquatic vegetation in other contexts, but not
under NWP 48. These commenters said that the Clean Water Act
regulations provide for protection of special aquatic sites, which
include ``vegetated shallows'' and that submerged aquatic vegetation
beds are considered vegetated shallows. One commenter said that while
the Corps states that all activities and structures must avoid
submerged aquatic vegetation, but it doesn't apply that principle to
commercial shellfish mariculture activities.
While the Clean Water Act Section 404(b)(1) Guidelines provide a
greater degree of protection to vegetated shallows (submersed aquatic
vegetation) as special aquatic sites compared to aquatic resources that
are not special aquatic sites, the Guidelines do not prohibit
discharges of dredged or fill material into vegetated shallows (i.e.,
submerged aquatic vegetation beds). The 404(b)(1) Guidelines only apply
to discharges of dredged or fill material. They do not apply to
activities authorized under Section 10 of the Rivers and Harbors Act of
1899.
One commenter stated that submerged aquatic vegetation beds provide
numerous ecosystem services including improving water quality,
providing nursery habitat for commercial and recreationally significant
fish and invertebrates, buffering shorelines from erosion, and
sequestering carbon. Because of these additional functions performed by
submerged aquatic vegetation, this commenter said that bivalve
shellfish mariculture cages do not do any of these things and cannot be
considered functionally equivalent habitat to submerged aquatic
vegetation.
As discussed in the 2020 Proposal and the national decision
document for NWP 48, it is the bivalves that perform a number of the
same ecological functions as submerged aquatic vegetation, not the
structures in which these bivalves are grown. However, commercial
shellfish mariculture structures do provide structural habitat for a
wide variety of aquatic organisms, including substrate for organisms to
attach to, and some aquatic organisms feed on the attached organisms.
Structures used for commercial shellfish mariculture activities can
slow the movement of water, and help reduce erosion of nearby
shorelines. These impacts would be considered during the review of a
PCN for a new or existing shellfish mariculture activity.
One commenter noted that the argument that shellfish aquaculture
activities only temporarily impact submerged aquatic vegetation is not
accurate because leases issued for shellfish aquaculture vary in
duration but are generally 5-20 years to ensure any investment in the
enterprise is worthwhile. This commenter said that the word
``temporary'' is a highly relative and generally misleading descriptor.
It is not the duration of the lease for shellfish mariculture
activities that determines whether commercial shellfish mariculture
activities have temporary impacts on submerged aquatic vegetation.
Commercial shellfish mariculture operators might not cultivate bivalve
shellfish continuously during the period the lease is in effect. The
operator may let some areas within a leased area to go fallow for a
period of time, to reduce adverse effects to the benthic community. The
Corps agrees that the term ``temporary'' is a relative term, but
disagrees that it is misleading. What constitutes a temporary impact
depends in part on how much time it takes an organism or an ecosystem
to recover from a disturbance, and how resilient and resistant the
species or ecosystems are to disturbances. Coastal waters are highly
dynamic environments subjected to periodic disturbances, both natural
and man-made.
Several commenters concurred with the Corps' view that commercial
shellfish mariculture activities typically only has temporary impacts
on submerged aquatic vegetation and these plants can sustain a healthy
coexistence. A few commenters noted that mechanical harvesting has been
found to not negatively impact native eelgrass and may even enhance it.
One commenter stated that the positive ecosystem services (e.g., better
water quality, habitat creation, and ecosystem studies) provided by
bivalve shellfish mariculture activities outweigh the temporary nature
of any perceived negative impacts. The habitat created by shellfish
aquaculture increases species richness and diversity of both benthic
and epibenthic organisms. This three-dimensional habitat is utilized by
many commercially valuable species, such as Dungeness crab and
flatfishes. The Corps acknowledges these comments. These beneficial
effects have informed the Corps' decision to reissue NWP 48 as
discussed because it will have no more than a minimal individual or
cumulative adverse environmental effects.
One commenter noted that farming methods such as bottom culture
propagation tends to focus on the cultivation of larger older shellfish
with large time intervals between harvests, which results in short term
impacts at harvest with long periods for recovery and result in no
permanent losses of submerged aquatic vegetation. This commenter said
that the persistence of eelgrass along the coast demonstrates that
shellfish mariculture and eelgrass can coexist and have for over a
century. Furthermore, commercial shellfish mariculture operators have
long understood the best way to propagate eelgrass is to plant oysters,
which creates optimal habitat allowing eelgrass to expand due to
decreased current over the tide flats. This commenter also said that
the bivalve shellfish, as filter feeders, remove large amounts of
waterborne nutrients resulting in cleaner water which facilitates
photosynthesis, expanding habitable ranges of eelgrass. The Corps
acknowledges these comments. These beneficial effects have informed the
Corps' decision to reissue NWP 48 as discussed because it will have no
more than a minimal individual or cumulative adverse environmental
effects.
Several commenters recommended revising the definition of
mechanical harvest so that they are not classified as ``dredge or
fill'' activities because it is too broad and lumps many methods
together and lacks clarity. These commenters said that mechanical
harvesting by dragging a metal basket along the tide flats to gently
tumble harvestable oysters does not result in a discharge of dredge or
fill material and should be exempt from section 404 jurisdiction.
Furthermore, these commenters said that these activities do not create
ditches, channels, or substantially redeposit excavated soil material
and none of the harvest tools are designed to remove large quantities
of material to improve the navigability of waters. These commenters
said that the sediment that may be disturbed during harvest should be
considered as incidental fallback under 33 CFR 323.2(d)(1).
Mechanical harvesting activities generally do not result in
discharges of fill material, as that term is defined at 33 CFR
323.2(f). However, mechanical harvesting activities may result in
discharges of dredged material, depending on how they are conducted.
The term ``discharge of dredged material'' is defined at 33 CFR
323.2(d) to include the ``addition of dredged material into, including
redeposit of dredged material other than incidental fallback within,
the waters of the United States.'' Some mechanical harvesting
[[Page 2800]]
activities may result in incidental fallback and not require section
404 authorization while other mechanical harvesting activities may
result in additions of dredged material into waters of the United
States that are not incidental fallback, and therefore require section
404 authorization. Mechanical and hydraulic harvesting activities that
redeposit sediment in a different area of the bottom of the waterbody
that the area from which the sediment was removed is considered a
``discharge of dredged material'' and therefore requires section 404
authorization. These discharges of dredged material into waters of the
United States are authorized by NWP 48.
A commenter noted that in the statement ``mechanical harvesting can
include grading, tilling, and dredging the substrate of the waterbody''
that the term ``grading'' does not describe shellfish culture methods.
A couple of commenters suggested that shellfish mariculture harvest
activities should be regulated like wild-harvest shellfisheries (e.g.,
as they are regulated in NWP 4). This commenter said that both wild and
cultured shellfish are state-managed resources, with the exception of
many tidelands in Washington, and should not require additional
oversight and regulation by federal authorities. This commenter also
stated that harvesting activities do not involve structures and do not
impact navigation in a way that should trigger regulation under the
Section 10 of the Rivers and Harbors Act of 1899.
Mechanical harvesting activities may move sediment in a waterbody
in a manner that is not considered incidental fallback. These
activities would require section 404 authorization under the Corps'
definition of ``discharge of dredged material.'' Nationwide permit 4
authorizes discharges of dredged or fill material associated with fish
and wildlife harvesting, enhancement, and attraction devices and
activities, including clam and oyster digging. The Corps has
jurisdictional authority in Washington State for activities regulated
under Section 10 of the Rivers and Harbors Act of 1899 and Section 404
of the Clean Water Act. Mechanical harvesting activities generally meet
the definition of ``work'' at 33 CFR 322.2(c) for the purposes of
Section 10 of the Rivers and Harbors Act of 1899, and are authorized by
NWP 48.
One commenter requested that the Corps add a statement in the final
rule that acknowledges that the accumulation of sediment around
shellfish farming gear may be considered beneficial in certain
environments, as well as provision of year-round durable, structured
three-dimensional habitat. The Corps declines to add the requested
statement because the potential benefits would need to be determined on
a case-by-case basis, and the durability of those sediment
accumulations is influenced because water movements that could cause
that sediment to be re-suspended in the water column.
One commenter said that the Corps must comply with ESA Section 7
and the Magnuson-Stevens Act prior to issuing NWP 48. A few commenters
stated that in all areas where submerged aquatic vegetation exists, it
is designated essential fish habitat under the Magnuson-Stevens Fishery
Conservation and Management Act. These commenters said that removal of
the \1/2\-acre limit for direct impacts to submerged aquatic vegetation
fails to acknowledge submerged aquatic vegetation as essential fish
habitat and the need for consultation with NMFS for activities that may
adversely affect essential fish habitat. These commenters asserted that
the Corps must consult on a nationwide programmatic basis because
essential fish habitat is adversely affected by shellfish mariculture
activities.
The NWP program's compliance with the essential fish habitat (EFH)
consultation requirements of the Magnuson-Stevens Fishery Conservation
and Management Act is achieved through EFH consultations between Corps
districts and NMFS regional offices. This approach continues the EFH
Conservation Recommendations provided by NMFS Headquarters to Corps
Headquarters in 1999 for the NWP program. Corps districts that have EFH
designated within their geographic areas of responsibility coordinate
with NMFS regional offices, to the extent necessary, to develop NWP
regional conditions that conserve EFH and are consistent the NMFS
regional EFH Conservation Recommendations. If a district engineer
determines a proposed NWP 48 activity may adversely affect essential
fish habitat, he or she will conduct EFH consultation with NMFS. Where
there is a requirement to consult on EFH, consideration of direct
impacts to submerged aquatic vegetation caused by new and existing
commercial shellfish mariculture activities would occur regardless of
the PCN threshold of \1/2\-acre. In response to an EFH assessment
prepared by the Corps, the NMFS may provide EFH conservation
recommendations to address potential impacts to submerged aquatic
vegetation. As discussed in Section III.D of this final rule, the Corps
has prepared a biological assessment for this rulemaking activity and
determined that the issuance of the NWPs has no effect on listed
threatened and endangered species and designated critical habitat, as
well as species proposed for listing and proposed designated critical
habitat.
One commenter stated that significant changes to NWP 48 are not
appropriate until the national decision document is finalized and
deemed sufficient. This commenter said the draft decision document
fails to satisfy the requirements of the National Environmental Policy
Act and the Clean Water Act, and that it fails to properly acknowledge
the impacts of mariculture on benthic habitat, fish communities, birds,
water quality and substrate characteristics. Several commenters stated
that the proposed revisions to the national decision document for NWP
48 do not fairly represent the conclusions of authors of the cited
literature, in some cases omitting relevant information and in others
misrepresenting study results and conclusions.
The purpose of the national decision document is to provide
information for the decision on whether to reissue NWP 48. The national
decision document discusses the positive and negative impacts of
commercial shellfish mariculture activities on benthic habitat, fish
communities, birds, water quality and substrate characteristics. The
Corps has considered this information and determined that NWP 48 will
not have more than a minimal individual or cumulative adverse
environmental effects.
One commenter said that the Corps describes no studies in its
decision document to verify its claim that commercially-raised
shellfish help improve water quality. One commenter noted that the
Corps acknowledges throughout the environmental consequences, public
interest, and 404(b)(1) Guidelines Analysis, some negative impacts, but
then fails to assess them and instead focuses only on positive impacts.
This commenter said that the impacts from mechanical and hydraulic
dredging are barely mentioned, with no assessment of their harmful
impacts to the same degree as the supposed benefits from shellfish
aquaculture.
The Corps discusses, in numerous places, the water quality benefits
of filter-feeding bivalves that are cultivated by commercial shellfish
mariculture activities. The Corps acknowledges that commercial
shellfish mariculture activities cause adverse and beneficial
[[Page 2801]]
environmental effects. Throughout the draft and final national decision
documents, the Corps discusses the negative and positive effects of
harvesting activities.
One commenter identified errors in projected use and acreage
impacted over the 5-year period NWP 48 is anticipated to be in effect.
This commenter notes that the draft NWP 48 decision document states
that the Corps estimates this permit will be used approximately 336
times per year on a national basis, resulting in impacts to
approximately 13,360 acres of waters of the United States. It then
states the Corps estimates that approximately 1,680 activities could be
authorized over a five-year period until the NWP expires, resulting in
impacts to approximately 40,080 acres. While 1,680 is five times the
annual use figure (336), five times the annual acreage figure (13,360)
is 66,800. One commenter requested that the Corps provide documentation
on the number of permit request over the last 10 years that exceeded
the \1/2\-acre limit, and of those activities, how many ultimately
received a permit through regional or individual permit process, and
what conditions were applied to those applications. One commenter
stated that the Corps claims to have no duty to use any quantitative
data, but has issued NWP 48 since 2007 and should be able after all
these years to provide some quantitative data about loss of seagrasses,
natural habitats, etc. One commenter recommended that the Corps pursue
a quantitative analysis of the environmental effects of shellfish
mariculture for habitat alterations, climate change, invasive species,
overharvesting and exploitation, and pollution.
Nationwide permit 48 authorizes structures and work in navigable
waters of the United States and discharges of dredged or fill material
into waters of the United States for both existing (on-going) and new
commercial shellfish mariculture activities. Many of the activities
authorized by NWP 48 are on-going activities that require
reauthorization each time the current NWP 48 expires and is replaced by
a reissued NWP 48. Nationwide permits can be issued for period of no
more than 5 years (see Section 404(e) of the Clean Water Act). The
acreage of projected impacts in the national decision document for NWP
48 includes many on-going commercial shellfish mariculture activities,
many of which have been in operation for decades. These on-going
commercial shellfish mariculture activities have been part of the
current environmental setting for years, and it is the current
environmental baseline against which the degree of severity of adverse
environmental effects is assessed to determine eligibility for NWP
authorization (i.e., whether the individual and cumulative adverse
environmental effects caused by commercial shellfish mariculture
activities during the 5-year period the NWP is in effect are no more
than minimal).
The Corps has revised the national decision document to correct the
errors in its estimates of potential use of this NWP and authorized
impacts. However, it should be noted that these are estimates of
projected use over the 5-year period the NWP is anticipated to be in
effect. With respect to the removal of the \1/2\-acre limit for direct
impacts to submerged aquatic vegetation caused by new commercial
shellfish mariculture activities, the Corps is only required to provide
an estimate of the number of activities that might occur during the
period this NWP is in effect. It is not necessary to provide data on
how many commercial shellfish mariculture activities were authorized by
regional general permits or individual permits.
The Council on Environmental Quality's NEPA regulations at 40 CFR
parts 1500-1508 do not require quantitative analyses of potential
environmental impacts. With respect to the 404(b)(1) Guidelines, 40 CFR
230.7(b)(3) requires cumulative effects to be analyzed by estimating
the number of discharges expected to occur under the NWP while it is in
effect. The environmental impacts of authorized activities during the
period the NWP is in effect is dependent on the current environmental
settings in which these activities will occur, and quantitative data on
those current environmental settings is not available. It should also
be noted that context is important, because these activities are
occurring in coastal waters that have been altered by human activities
and natural processes for thousands of years, and continue to be
impacted by coastal watershed land use, point source pollution, non-
point source pollution, fishing activities, recreation, and other
disturbances, not just commercial shellfish mariculture activities.
Several commenters stated it is unclear how mitigation can both be
unnecessary and something the Corps is relying on to avoid cumulative
impacts. Further, several commenters stated that the Corps relies
heavily on mitigation at a district level, but fails to actually
describe the possible effects (direct, indirect and cumulative) from
shellfish aquaculture activities or how these unknown mitigation
measures will actually avoid more than minimal adverse impacts. Any
individual mitigation measures will only be attached if a permittee is
required to submit a pre-construction notification, which will likely
be few and far between.
For commercial shellfish mariculture activities, the Corps
generally does not require compensatory mitigation because these
activities do not cause losses of waters of the United States.
Paragraph (a) of general condition 23 requires permittees to design
their projects to avoid and minimize adverse effects, both temporary
and permanent, to waters of the United State to the maximum extent
practicable on the project site. Many of the NWP general conditions
consist of mitigation measures to avoid and minimize impacts. When
determining whether to require mitigation to ensure that a particular
NWP activity results in no more than minimal individual and cumulative
adverse environmental effects, the district engineer will consider the
direct, indirect, and cumulative effects, as required by paragraph 2 of
Section D, District Engineer's Decision. If the district engineer
requires mitigation for an NWP activity, he or she will add conditions
to the NWP authorization (see 33 CFR 330.1(e)(3)) that are directly
related to the impacts of the proposal, appropriate to the scope and
degree of those impacts, and reasonably enforceable (see 33 CFR
325.4(a)).
One commenter stated that the Corps said that ``standard and best
management practices'' can reduce impacts but fails to explain what
these are and how they will mitigate impacts. One commenter said that
the Corps claims commercially-reared bivalves improve water quality but
fails to assess water quality impacts by deferring to district
engineers and water quality certifications under Clean Water Act
section 401, but impacts to water quality must be assessed before
granting NWPs. One commenter said that the Corps fails to discuss the
context and intensity factors that might indicate that this proposed
NWP will have a ``significant impact to the human environment'' and
thus requires an environmental impact statement.
As stated in the 2020 Proposal, species-specific or regional
standards and best management practices for commercial shellfish
mariculture activities may be appropriate as regional conditions
approved by division engineers (see 85 FR 57331). In the national
decision document, the Corps has discussed potential impacts to water
[[Page 2802]]
quality as well as potential benefits to water quality that may result
from commercial shellfish mariculture activities. In addition, the
Corps has explained that cultivated bivalves are not considered a
pollutant under the Clean Water Act. After considering the information
in the national decision document for this NWP, including the potential
benefits and detriments caused by commercial shellfish mariculture
activities, there is no evidence that these activities cause a
significant impact to the human environmental and thus no environmental
impact statement is required.
One commenter stated the alternatives analysis is inadequate. The
commenter asserts that the Corps lists the ``no action'' alternative
but barely analyzes it, strangely concluding that it would somehow have
more substantial adverse environmental consequences. The ``national
modification'' alternative is not an alternative, but the proposed NWP
48 and the ``regional modification'' is also not an alternative because
it includes no conditions or changes from the proposed NWP 48.
The national decision document discusses alternatives. In the
Council on Environmental Quality's NEPA regulations that were published
in the Federal Register on July 16, 2020, the preamble to the final
rule at 85 FR 43323 states that an agency does not need to include a
detailed discussion of each alternative in an environmental assessment.
In the national decision document, the Corps briefly discussed the
environmental consequences of each alternative.
One commenter said that the Corps should impose monitoring
requirements that would ensure that NWP terms and conditions, including
those resulting from subsequent exercises in discretionary authority,
would be adequately policed. In response, Corps districts can conduct
compliance inspections for authorized activities, to ensure that those
activities are conducted in accordance with any conditions added to the
NWP authorization. The Corps district will take appropriate actions to
address non-compliance with permit conditions.
Several commenters approved of the reiteration and clarification
that the discharge of pesticides is regulated under Section 402 of the
CWA and not Section 404. They suggested that the final rule clearly
state that operators may be permitted to use pesticides to control
agricultural pests and predators instead of just predators. One
commenter said that the statement regarding commercial shellfish
mariculture operations using chemicals to control fouling organisms is
incorrect because chemical use or the potential introduction of toxic
materials is regulated by the Interstate Shellfish Sanitation
Conference. One commenter said that commercial shellfish mariculture
operators may use herbicides to control invasive, noxious weeds on
commercial clam beds.
The Corps does not have the authority to control the use of
pesticides, herbicides, and antifouling agents in commercial shellfish
mariculture activities. Use of some of these chemicals may be regulated
under other federal or state laws and regulations administered by other
agencies.
One commenter said that while gear sometimes escapes from
commercial shellfish farms despite growers' best efforts to ensure it
remains secured, shellfish farmers do not discard equipment into the
marine environment. This commenter requested that the Corps revise the
national decision document to make it clear that growers are not
discarding equipment, but equipment may wash away from the project site
or move by other mechanisms. This commenter also said that NWP general
condition 6 addresses the use of trash in the NWP program. One
commenter said that the use of plastics gear for commercial shellfish
mariculture activities adds plastic pollution to the ocean and beaches
through plastic debris and this plastic can break down further into
microplastics, which can impact wildlife, aesthetics, and food safety.
The Corps has revised the national decision document to clarify
that some materials used for commercial shellfish mariculture
activities may wash away from the project area. General condition 6
does not address trash or garbage that may be associated with
commercial shellfish mariculture activities. General condition 6
prohibits the use of trash as fill material. Trash and garbage are not
considered fill material for the purposes of section 404 of the Clean
Water Act (see 33 CFR 323.2(e)(3)).
This NWP is reissued with the modifications discussed above.
(10) NWP 50. Underground Coal Mining Activities
The Corps proposed to modify this NWP to remove the 300 linear foot
limit for losses of stream bed, which is discussed above in Section
II.F. The responses to comments on the proposal to remove the 300
linear foot limit are provided in Section II.F. In addition, the Corps
proposed to the reference to integrated permit processing procedures
and the requirement for written verification from the Corps before
proceeding with the authorized activities.
Many commenters stated they are opposed to the default
authorization if the Corps does not respond to the PCN submittal within
45 days. Numerous commenters said they support the automatic
authorization if the Corps project manager does not respond to the
complete PCN within 45 days. One commenter objected to the removal of
PCN requirements. A few commenters said that in order to further
expedite permitting for mining project, no PCN should be required for
activities authorized by this NWP.
The Corps removed the requirement for the permittee to obtain
written authorization before commencing the activity to be consistent
with the other NWPs that have a \1/2\-acre limit for discharges of
dredged or fill material into non-tidal waters of the United States
(e.g., NWPs 29, 39, 40, 42, 43, 44, 51, and 52). The Corps did not
propose to remove any PCN requirements from this NWP. All activities
authorized by this NWP require PCNs. The Corps is retaining the PCN
requirements for this NWP to provide activity-specific review by
district engineers to ensure that the activities authorized by this NWP
result in no more than minimal individual and cumulative adverse
environmental effects.
A few commenters said that the applicability of this NWP would be
reduced if the applicant must now include coal preparation and
processing activities outside of the underground mine site as a single
and complete project under NWP 50. One commenter stated the Corps
provided no justification for the deletion of the Note regarding the
use of NWP 21, coupled with NWP 50, for coal preparation and processing
activities outside of the underground mine. One commenter expressed
support for the removal of the integrated permitting process language.
One commenter stated that NWP should state that the project proponent
cannot begin the authorized activity until the activity is formally
approved by the Department of Interior's Office of Surface Mining or
the state. Several commenters asserted the NWP 50 should be revoked
because the effects of coal mining are significant to the environment
and should be evaluated under an individual permit.
Even if the Note were not removed, single and complete underground
coal mining activities with coal preparation and processing activities
outside the underground mine site are subject to general condition 28,
use of multiple NWPs. If NWP 50 and 21 are combined to authorize a
single and complete
[[Page 2803]]
project, the activity would be subject to the \1/2\-acre limit. The
Corps removed the language referencing integrated permit processing
procedures, since those procedures have never been developed for this
NWP since that text was added to the NWP in 2007 (see 72 FR 11184).
Project proponents may be required to obtain separate
authorizations from the Department of Interior's Office of Surface
mining or the state, but those authorizations are a separate process
from the Corps' NWP authorization process. Authorization by an NWP does
not obviate the need to obtain other federal, state, or local permits,
approvals, or authorizations required by law. (See item 2 in Section E,
Further Information.) Division engineers can add regional conditions to
this NWP to restrict or prohibit discharges of dredged or fill material
into certain wetland types if those discharges are likely to result in
more than minimal individual and cumulative adverse environmental
effects. District engineers can also exercise discretionary authority
to modify, suspend, or revoke an NWP after reviewing the PCN, to ensure
that the NWP authorizes only those activities that result in no more
than minimal individual and cumulative adverse environmental effects.
This NWP is reissued as proposed.
(11) NWP 51. Land-Based Renewable Energy Generation Facilities
The Corps proposed to modify this NWP to remove the 300 linear foot
limit for losses of stream bed, which is discussed above in Section
II.F. The responses to comments on the proposal to remove the 300
linear foot limit are provided in Section II.F.
One commenter expressed support for the PCN threshold for losses of
greater than \1/10\-acre of waters of the United States and does not
support requiring PCNs for all activities authorized by this NWP. One
commenter said that these activities should be prohibited from channel
migration zones and floodplains because they are likely to directly or
indirectly affect critical habitat, essential fish habitat, and
habitats occupied by listed species. This commenter stated that
structures built in these zones are at heightened risk to flooding and
future flood dynamics associated with climate change. This commenter
also said that any impacts over \1/10\-acre should require mitigation.
The Corps did not propose to change the \1/10\-acre PCN threshold
for this NWP that was adopted in the 2017 NWP 51. Activities authorized
by this NWP must comply with general condition 10, fills in 100-year
floodplains. If the district engineer determines a proposed activity
may adversely affect essential fish habitat, he or she will conduct
essential fish habitat consultation with NMFS. If the district engineer
determines the proposed activity may affect listed species or
designated critical habitat, she or he will conduct ESA section 7
consultation with the U.S. FWS and/or NMFS. In accordance with general
condition 23 and 33 CFR 330.1(e)(3), district engineers determine on a
case-by-case basis whether specific activities authorized by this NWP
should require compensatory mitigation or other forms of mitigation to
ensure the authorized activities result in no more than minimal
individual and cumulative adverse environmental effects.
One commenter recommended adding roads constructed to develop,
maintain, and repair land-based renewable generation facilities to Note
1. One commenter stated that the NWP 51 makes reference to a
distribution system as utility lines constructed to transfer the energy
produced by a land-based renewable energy generation facility, but
elsewhere in the proposed rule it refers to electrical lines as
``transmission lines'' which is an undefined term. Two commenters
suggested revising Note 2 to state that NWPs C and 14 may be used to
provide DA authorization for the construction, maintenance, repair, and
removal or utility lines and/or road crossings. This commenter also
said that the Corps should clarify that the applicant can specify which
NWP it wants to use for utility lines and/or road crossings.
Note 1 only addresses electric utility lines used to transfer the
electrical energy generated by these facilities to a distribution
system, regional grid, or other facility. Transmission lines are part
of electrical energy distribution systems to move the electricity from
generation facilities to end users. Note 1 has been modified to
specifically refer to electric utility lines because these land-based
renewable energy generation facilities generate electrical energy. The
Corps has revised Note 1 to reference NWP 57, which authorizes electric
utility line and telecommunications activities. Activities authorized
by NWP 51 are non-linear projects, while electric utility lines used to
transport the generated electrical energy to end users and others are
linear projects that are more appropriately authorized by NWP 57. Roads
that extend to and from the land-based renewable energy generation
facility are also linear projects, and crossings of waters of the
United States for these roads are more appropriately authorized by NWP
14. This NWP is reissued with the modifications discussed above.
(12) NWP 52. Water-Based Renewable Energy Generation Pilot Projects
The Corps proposed to modify this NWP to remove the 300 linear foot
limit for losses of stream bed, which is discussed above in Section
II.F. The responses to comments on the proposal to remove the 300
linear foot limit are provided in Section II.F.
Many commenters said that the Corps should modify NWP 52 so that it
is not limited to pilot projects, because this restriction limits
project proponent's ability to utilize the NWP to facilitate the
development of off-shore wind generation projects. These commenters
said that the impacts are the same regardless of whether a water-based
renewable energy generation project is a pilot project or a full-scale
development project, and that the adverse environmental effects caused
by these activities will be no more than minimal. A couple of
commenters noted that as off-shore wind energy generation continues to
grow it will become more crucial that these projects are able to obtain
Corps authorization in a timely and efficient manner. A couple of
commenters said that these projects should require individual permits
and should not be authorized by an NWP.
The Corps believes that the construction of permanent water-based
renewable energy generation facilities should be authorized by
individual permits instead of an NWP because of the potential for
permanent activities to result in more than minimal adverse
environmental effects. District engineers can develop regional general
permits to authorized permanent water-based renewable energy generation
facilities.
One commenter stated that the \1/2\-acre limit and the requirement
for PCNs for all proposed activities should be retained. One commenter
recommended changing the PCN threshold to require PCNs for losses of
greater than \1/10\-acre of waters of the United States. A couple of
commenters said that Note 1 should be revised to reflect authorization
of transmission lines by NWP C rather than NWP 12.
The Corps is retaining the \1/2\-acre limit and the requirement
that all authorized activities require PCNs. The Corps has revised Note
1 to reference electric utility lines and NWP 57, which authorizes
electric utility line and telecommunications activities.
Several commenters stated that these activities should not be
authorized western Washington State without tribal consent in areas
with tribal treaty fishing rights. These commenters said
[[Page 2804]]
that allowing floating solar panels up to \1/2\-acre in size in
navigable waters adds additional obstructions to tribal fisherman
trying to exercise their fishing rights. One commenter stated that
floating solar panels, if installed, need proper monitoring
requirements with the ability to have the projects removed if the
injuries to fish reach a certain threshold. One commenter said that
pilot projects for experimental purposes should include a requirement
for robust information gathering to inform decision makers of
ecological impacts of these energy generating structures.
Division engineers can add regional conditions to this NWP to help
ensure compliance with general condition 17, tribal rights. During this
rulemaking process, Corps districts have been consulting and
coordinating with tribes to identify regional conditions and
coordination procedures to help ensure compliance with general
condition 17. The Corps disagrees with imposing long-term information
gathering requirements to monitor the ecological impacts that might be
caused by these activities. The information in PCNs should be
sufficient for district engineers to determine whether the adverse
environmental effects caused by the authorized activities are no more
than minimal.
This NWP is reissued with the modifications discussed above.
(13) NWP 55. Seaweed Mariculture Activities
The Corps proposed this new NWP as NWP A, to authorize structures
in navigable waters of the United States, including federal waters over
the outer continental shelf, for seaweed mariculture activities. In the
first sentence of this NWP, the Corps added ``and estuarine'' to make
this NWP consistent with proposed new NWP B for finfish mariculture
activities with respect to the waters in which these two NWPs may be
used to authorize activities under Section 10 of the Rivers and Harbors
Act of 1899. The omission of ``and estuarine'' in the proposed NWP A
was a drafting error.
The Corps removed the phrase ``and work'' from this NWP because
this NWP only authorizes structures, and this NWP does not authorize
any of the operational aspects of seaweed mariculture activities. The
operation of a seaweed mariculture facility does not constitute
``work'' as that term is defined at 33 CFR 322.2(c) for the purposes of
Section 10 of the Rivers and Harbors Act of 1899. Section 322.2(c)
defines ``work'' as ``any dredging or disposal of dredged material,
excavation, filling, or other modification of a navigable water of the
United States.'' After the seaweed mariculture structure is installed,
subsequent operations to produce seaweed do not physically modify
navigable waters of the United States in a manner that would be
considered ``work'' under the Act.
Several commenters expressed support for the issuance of new NWP A.
One commenter suggested combining NWPs 48 and A into one NWP instead of
issuing separate NWPs. One commenter said that issuing NWP A would
reduce barriers to entry for seaweed mariculture activities. Another
commenter supported the issuance of NWP A because kelp and seaweed are
winter crops and would help provide year-round revenue sources for
coastal commercial communities. A few commenters expressed support for
NWP A because growth of marine plants improves water quality and
provides ecosystem services.
The Corps is keeping NWPs 48 and proposed new NWP A separate
because NWP 48 activities occur primarily in nearshore waters and NWP A
can be used to authorize activities in both nearshore waters and
federal waters on the outer continental shelf. The Corps acknowledges
the economic benefits of providing an NWP to authorize seaweed
mariculture activities that result in no more than minimal adverse
environmental effects, as well as the ecological benefits that may be
provided by the cultivated seaweeds, such as water quality benefits
through the assimilation of nutrients and habitat benefits for some
aquatic species.
Several commenters said they support the inclusion of multi-trophic
species production in NWP A. One commenter supported including multi-
trophic species production as long as it is voluntary and not a
requirement of the NWP. One commenter said that multi-trophic
activities should not be authorized under an NWP until an industry
standard has been established. A few commenters stated multi-trophic
activities should be authorized under by individual permits to provide
an appropriate level of environmental review. One commenter said PCNs
including that multi-trophic activities should be coordinated with
states. A few commenters asserted that the text of NWP A should clarify
that multi-trophic activities do not include finfish cultivation. One
commenter stated that multi-trophic species mariculture could attract
protected species and result in greater risk of entanglement. A few
commenters said that the NWPs are appropriate only for activities with
more predictable outcomes and should not be used for experimental
industries.
The Corps has retained multi-tropic mariculture activities in this
NWP, to provide authorization for mariculturists that want to grow
seaweeds and bivalves on the same structures. Conducting multi-tropic
mariculture activities is optional, and a grower can choose to only
cultivate seaweeds. District engineers will review PCNs for proposed
NWP A activities to ensure that those activities will result in no more
than minimal individual and cumulative adverse environmental effects.
If the district engineer reviews a PCN and determines that the adverse
environmental effects will be more than minimal after considering any
mitigation proposed by the applicant, he or she will exercise
discretionary authority and require an individual permit. The Corps
does not believe it is necessary to require coordination of proposed
multi-tropic mariculture activities with states, but district engineers
can informally coordinate PCNs with states if they believe it is
appropriate to do so. If a mariculturist wants to grow finfish as part
of a multi-trophic mariculture operation, she or he should use NWP B
(which, as discussed below, is issued in this final rule as NWP 56),
which authorizes multi-trophic mariculture activities involving
finfish, seaweeds, and/or bivalves. There may be some risk of
entanglement or other forms of adverse impact in lines used for seaweed
mariculture activities, and that risk will be evaluated by district
engineers during the PCN review process. If the risk of entanglement
applies to ESA-listed species, the district engineer will conduct ESA
section 7 consultation with the U.S. FWS and/or NMFS as appropriate.
Multi-trophic mariculture activities have been conducted for a number
of years in other countries (Largo et al. 2016, Troell et al. 2009).
Several commenters said NWP A should not be issued because these
activities will result in more than minimal individual or cumulative
adverse environmental effects. Several commenters stated NWP A should
not be issued because the long-term cumulative impacts are unknown.
Many commenters expressed concern with the issuance of an NWP
authorizing seaweed mariculture activities because of the relative
unknown impacts and risks associated with these activities. One
commenter said that the social, economic, and environmental impacts
from seaweed mariculture are unknown. One commenter said that the
cumulative impact from the varying scale of aquaculture systems cannot
[[Page 2805]]
sufficiently be addressed under an NWP. Many commenters stated that
there is not sufficient information available to inform whether NWP A
would cause no more than minimal impacts. A few commenters said that
the Corps has not demonstrated that NWP A complies with the Clean Water
Act Section 404(b)(1) guidelines.
The Corps has issued this NWP after considering information on its
relatively small, if not beneficial, impact on marine ecosystems and
including mechanisms (e.g., PCNs required for all proposed activities)
to ensure that it authorizes only those seaweed mariculture activities
that result in minimal individual and cumulative adverse environmental
effects. In response to a PCN, district engineers will apply the 10
criteria listed in paragraph 2 of Section D, District Engineer's
Decision to determine whether the proposed activity can be authorized
by NWP 55, with or without additional permit conditions. Division
engineers may modify, suspend, or revoke this NWP on a regional basis
in accordance with the procedures at 33 CFR 330.5(c). The Clean Water
Act Section 404(b)(1) Guidelines do not apply to activities authorized
by this NWP because it only authorizes structures or work in navigable
waters of the United States under Section 10 of the Rivers and Harbors
Act of 1899. It does not authorize activities under Section 404 of the
Clean Water Act.
Several commenters said that NWP A would impact tribal rights and
treaty protected fishing grounds. One commenter requested additional
information and formal government-to-government consultation on
proposed new NWP A. One commenter objected to the issuance of NWP A
because it does not include required mitigation measures. One commenter
stated that mitigation measures should be considered for ESA-listed
species and tribal cultural and fishing issues. One commenter suggested
adding minimization measures to NWP A that are currently in place in
states that are already practicing seaweed mariculture operations.
Activities authorized by NWP A must comply with general condition
17, tribal rights. During the rulemaking process for the issuance of
this NWP, district engineers have been conducting consultation and
coordination with tribes to identify regional conditions and
coordination procedures to facilitate compliance with general condition
17. In response to a PCN, a district engineer can require mitigation
measures to help ensure that the authorized activity results in only
minimal individual and cumulative adverse environmental effects. During
the development of this NWP, the Corps did not identify any mitigation
measures that should be added to this NWP, other than the general
conditions that apply to all NWPs. Mitigation measures for ESA-listed
species are more appropriately identified during the ESA section 7
consultation process. If states have developed mitigation measures for
seaweed mariculture activities, division engineers can consider adding
those mitigation measures as regional conditions to this NWP.
Several commenters said that NWP A should include a PCN
requirement. One commenter expressed support for requiring PCNs for new
seaweed mariculture operations. One commenter said that PCNs should not
be required if existing permitted bivalve shellfish farms want to add
seaweed into their operations. One commenter stated that the U.S. Coast
Guard be notified before issuing an NWP A verification. One commenter
recommended requiring the PCN to include information identifying the
proposed location of operations to review competing stakeholder uses.
One commenter said that all PCNs for these activities must identify all
gear specifications, production duration, stocking and harvesting
times, and gear modifications related to avoiding or mitigating
protected species interactions. Many commenters stated that PCNs for
NWP A activities should require documentation of compliance with
specific design and operational standards. One commenter said PCNs
required for these activities should include information the
performance of anchoring systems during severe weather events to
minimize damage or loss. One commenter said that PCNs for these
activities should state which commercial fisheries activities (wild or
mariculture) might have the potential to be affected by the proposed
activity or include a vicinity map indicating the location of the
proposed activities.
Proposed new NWP A requires PCNs for all proposed activities.
Project proponents may be required to notify the U.S. Coast Guard or
comply with U.S. Coast Guard requirements for marking or lighting these
structures. It is not the responsibility of the Corps to notify the
U.S. Coast Guard of these activities. Some Corps districts have
developed local coordination procedures with the U.S. Coast Guard.
Paragraph (b)(2) of general condition 32 requires the PCN to include
the location of the proposed activity. The Corps does not have the
authority to regulate production duration and stocking and harvesting
times. If the project proponent wants to modify the seaweed mariculture
structures that are regulated under Section 10 of the Rivers and
Harbors Act of 1899, he or she must notify the district engineer to
request a modification of the NWP verification. Corps district
regulatory staff do not have the legal authority or technical expertise
to evaluate design or operational standards, or the structural
integrity of the seaweed mariculture structures. It is the
responsibility of the permittee to properly design the seaweed
mariculture structures and ensure that they are properly maintained in
accordance with general condition 14, proper maintenance. The Corps
declines to require the PCN to identify which commercial fisheries
species might be affected by the proposed seaweed mariculture activity
because impacts to EFH are already considered when district engineers
review PCNs and conduct EFH consultation with NMFS when they determine
proposed NWP activities may adversely affect EFH.
Many commenters said that seaweed mariculture activities should
require individual permits. Several of these commenters stated that
individual permits for these activities are appropriate because the
public notice process would allow ample coordination with the affected
public. A few commenters said that there is insufficient industry
standardization within mariculture systems to issue an NWP for these
activities and these activities should require individual permits. A
few commenters said that individual permits should be required for
these activities to allow proper environmental review and coordination
with state natural resource agencies.
The Corps believes that there are seaweed mariculture activities
requiring authorization under Section 10 of the Rivers and Harbors Act
of 1899 that will cause only minimal individual and cumulative
environmental effects (see 33 CFR 322.2(f)) and are appropriate for
authorization by NWP. If a district engineer reviews a PCN for a
proposed seaweed mariculture activity and determines that the adverse
environmental effects will be more than minimal after considering
mitigation proposed by the applicant, he or she will exercise
discretionary authority and require and individual permit for the
proposed activity. In addition, division engineers have the authority
to modify, suspend, or revoke this NWP on a regional basis in response
to concerns for the aquatic environment or for any factor of the public
interest (see 33 CFR 330.1(d)). The development of industry
[[Page 2806]]
standards is not a prerequisite for NWP authorization, and many
activities that have long been authorized NWP do not have any industry
standards.
A few commenters stated that NWP A should require agency
coordination under paragraph (d) of NWP general condition 32. One
commenter said that NWP A PCNs should be coordinated with federal and
state natural resource agencies of adjacent states and that applicable
state permits must be obtained prior to the Corps issuing an NWP
verification for seaweed mariculture activities. Many commenters said
that seaweed mariculture activities should be coordinated with state
resource agencies and the public.
The activities authorized by this NWP may require consultation or
coordination with the U.S. FWS or NMFS. Consultation with the U.S. FWS
and/or NMFS is required for proposed activities that the district
engineer determines ``may affect'' listed species or designated
critical habitat. Essential fish habitat consultation with the NMFS is
required for any proposed activity that the district engineer
determines ``may adversely affect'' essential fish habitat. Corps
districts may develop informal coordination procedures with state
resource agencies. Activities authorized by NWPs do not involve
coordination with the public. Coordination with the public is only
require for activities authorized by standard individual permits.
One commenter said that seaweed mariculture activities authorized
by NWP A should be limited to small scale projects. One commenter
recommended adding a \1/2\-acre limit to this NWP. One commenter stated
that seaweed mariculture facilities for biofuels production are in the
range of over 1,000 hectares and issuing an NWP to authorize seaweed
mariculture activities at that scale would not sufficiently consider
the environmental risks. One commenter said that the necessary spatial
arrays required for seaweed mariculture would cause conflicts from
multiple existing offshore uses.
The Corps does not agree that this NWP should be limited to small-
scale project or activities less than \1/2\-acre in size. If a project
proponent submits a PCN for a large-scale seaweed mariculture activity,
and the district engineer determines the proposed activity will result
in more than minimal individual and cumulative adverse environmental
effects, he or she will exercise discretionary authority and require an
individual permit for the proposed activity. During the evaluation of
the PCN, the district engineer will evaluate potential conflicts in
resource uses, in accordance with the public interest review factors
identified in 33 CFR 320.4(a).
Many commenters stated that the seaweed species to be grown should
be the same indigenous genetic stock as found in the waters of the
proposed seaweed mariculture activity. One commenter said that the
terms and conditions of the proposed NWP address the introduction of
non-native species but not the role that mariculture may play in the
role of further spreading invasive or aquatic nuisance species. One
commenter stated that NWP A should impose rigorous operation emergency
response standards. One commenter stated that NWP A should have clear
requirements for removing derelict structures.
The Corps has modified this NWP to state that it prohibits the
cultivation of an aquatic nuisance species as defined in the
Nonindigenous Aquatic Nuisance Prevention and Control Act of 1990 or
the cultivation of a nonindigenous species unless that species has been
previously cultivated in the waterbody. Invasive or aquatic nuisance
species can spread or be introduced into new areas through a variety of
mechanisms, and the Corps does not have the authority to prevent the
spread or introduction of those species through those other mechanisms.
General condition 13 requires, to the maximum extent practicable, the
removal of temporary structures from navigable waters after their use
has been discontinued. For permanent structures, the Corps has added a
provision to this NWP to require the permittee to remove these
structures from navigable waters of the United States when those
structures will no longer be used for finfish mariculture activities or
multi-trophic mariculture activities.
One commenter recommended requiring the siting of NWP A activities
at least 200 meters away from corals, seagrass beds, mangroves,
critical habitat, and migration pathways. A few commenters asserted
that seaweed mariculture activities are known to impair water quality,
and special aquatic sites such as coral, seagrass, and mangroves are
especially susceptible to water quality impacts. A few commenters said
that seaweed mariculture facilities should not be permitted near
sensitive habitat areas or near marine protected areas. One Commenter
remarked that seaweed mariculture activities could result in economic
impacts to the region where these activities are located by interfering
with commercial and recreational fishing activities. One commenter said
that operations of seaweed mariculture activities could result in
aesthetic impacts to the region. One commenter expressed concerns with
potential impacts on navigation and public uses of the waterbody that
may be caused by seaweed mariculture activities. One commenter stated
that seaweed mariculture facilities should be distant from areas used
by the public. One commenter said that NWP A should be revised to
recognize that some state boundaries may extend beyond three nautical
miles from shore.
Based on the characteristics of regional ecosystems, division
engineers can add regional conditions to this NWP to site NWP A
activities specific distances from aquatic resources or areas that may
warrant additional protection, such as corals, seagrass beds,
mangroves, critical habitat, and migration pathways. Seaweed
mariculture activities cultivate macroalgae that take up nitrogen and
phosphorous and other nutrients from the water column and generally are
understood to improve water quality. Organic matter may be sloughed off
of the cultivated seaweeds, which can provide nutrients for benthic
communities. The seaweed grown at seaweed mariculture facilities can
provide economic benefits such as biofuels, food ingredients, and
pharmaceuticals. When reviewing PCNs, district engineers will evaluate
potential conflicts in use of navigable waters, such as fishing,
recreational, and military uses, as well as potential impacts to
aesthetics in the project area. Activities authorized by this NWP must
comply with general condition 1, navigation. Navigable waters are
available for a variety of public uses, as well as various types of
activities authorized for private use. Activities authorized for
private use often involve structures that require DA authorization
under Section 10 of the Rivers and Harbors Act of 1899, which may
include structures for seaweed mariculture activities. The variability
in state boundaries for the purposes of identifying the territorial
seas does not warrant any specific changes to NWP 55.
One commenter stated that shellfish farming activities are known to
spread pathogens and the proposed NWP would not sufficiently address
environmental concerns for offshore systems. A few commenters said
seaweed mariculture facilities should not be permitted to use
pesticides, herbicides, or pharmaceuticals. One commenter said that
existing shellfish mariculture facilities permitted under NWP 48 should
continue to be
[[Page 2807]]
authorized under NWP 48 rather than authorized by NWP A. One commenter
stated it would be more appropriate if seaweed was included under NWP
48 because bivalves are typically the primary cultivated species.
The Corps does not have the authority to take actions to control
the spread of pathogens. Pathogens can spread through a variety of
mechanisms in open systems such as oceans and estuaries. In addition,
the Corps does not have the authority to regulate the use of
pesticides, herbicides, and pharmaceuticals that might be used in
seaweed mariculture activities. In this final rule, the Corps has
issued separate NWPs for commercial shellfish mariculture activities
and seaweed mariculture activities. Under NWP A bivalves can be grown
with seaweeds are part of a multi-tropic mariculture activity.
A few commenters said that proposed new NWP A would have impacts on
ESA-listed species and designated critical habitat. One commenter
stated that ESA Section 7 consultation should be mandatory for all
seaweed mariculture projects. One commenter said that incidental take
permits under the ESA should be obtained before district engineers
issue NWP verifications for these activities. A few commenters said
that NWP A activities should have severe consequences for non-
compliance, including revocation of the NWP authorization.
Activities authorized by this NWP must comply with general
condition 18, endangered species. District engineers will review PCNs
for proposed seaweed mariculture activities and if the district
engineer determines the proposed activity may affect listed species or
designated critical habitat, he or she will conduct ESA section 7
consultation with the U.S. FWS or NMFS as appropriate. If the district
engineer initiates section 7 consultation with the U.S. FWS or NMFS,
the NWP verification cannot be issued until that consultation is
completed. District engineers will also take appropriate actions to
address non-compliance with the conditions in NWP A.
Proposed new NWP A is issued as NWP 55, with the modifications
discussed above.
(14) NWP 56. Finfish Mariculture Activities
The Corps proposed this new NWP as NWP B, to authorize structures
and work in navigable waters of the United States, including federal
waters over the outer continental shelf, for finfish mariculture
activities.
The Corps removed the phrase ``and work'' from this NWP because
this NWP only authorizes structures, and this NWP does not authorize
any of the operational aspects of finfish mariculture activities. The
operation of a finfish mariculture facility does not constitute
``work'' as that term is defined at 33 CFR 322.2(c) for the purposes of
Section 10 of the Rivers and Harbors Act of 1899. Section 322.2(c)
defines ``work'' as ``any dredging or disposal of dredged material,
excavation, filling, or other modification of a navigable water of the
United States.'' After the finfish mariculture structure is installed,
subsequent operations to produce finfish do not physically modify
navigable waters of the United States in a manner that would be
considered ``work'' under the Act.
Some commenters supported the issuance of this NWP and some
commenters opposed issuance of this NWP. A couple of commenters said
that this NWP does not authorize activities that are similar in nature.
Many commenters said that finfish mariculture activities should require
individual permits to give the public an opportunity to review proposed
activities. One commenter stated that finfish mariculture activities
could result in significant cumulative impacts on marine wildlife and
the environment, which cannot be properly assessed and mitigated. One
said that finfish mariculture activities in estuarine waters should
require individual permits because of the high risk of water quality
impacts, animal escapes, and habitat damage.
This NWP authorizes structures in navigable waters of the United
States for finfish mariculture activities. A category of activities for
an NWP is based on the general characteristics and uses of the
permitted activity. A category of activities is not based on potential
configurations of the regulated activities, or the size of those
activities. Concerns about the size of authorized activities and
potential adverse environmental effects can be addressed in part by
addition quantitative limits on the NWP. The Corps believes there are
finfish mariculture activities that can result in no more than minimal
individual and cumulative adverse environmental effects and are
appropriate for NWP authorization. In addition, the NWP regulations at
33 CFR part 330 include numerous provisions that allow district
engineers to exercise discretionary authority to require individual
permits for activities when the determine those activities will cause
more than minimal adverse environmental effects. Division engineers
have the authority to modify, suspend, or revoke an NWP on a regional
basis (see 33 CFR 330.5(c)). District engineers have the authority to
modify, suspend, or revoke an NWP authorization on a case-by-case basis
(see 33 CFR 330.5(d)). The potential individual and cumulative adverse
environmental effects caused by finfish mariculture activities will be
assessed by district engineers when they review PCNs for proposed
activities. For some of the adverse environmental effects identified by
commenters, the Corps lacks the authority to regulate the particular
activities that are the cause of those effects.
Several commenters recommended the development and implementation
of project-specific permit conditions to ensure that authorized
activities will have no more than minimal individual or cumulative
adverse environmental effects. Several commenters requested that NWP B
include conditions limiting the amount of feed, pesticides, herbicides,
pharmaceuticals that can be released in project waters. A couple of
commenters suggested NWP B require specific design and operation
standards, including depth and current velocity guidelines for net pen
siting class size. A commenter said that the geographic variability of
aquatic environments and their ecological functions would be
problematic when characterizing project impacts of finfish mariculture
activities on a national scale.
Project-specific conditions are more appropriately identified by
district engineers when they review PCNs for proposed NWP B activities.
If a proposed activity is authorized by NWP B, the district engineer
will add appropriate conditions to the NWP authorization to help ensure
that the adverse environmental effects are no more than minimal,
individually and cumulatively. Permit conditions must be directly
related to the impacts of the proposal, appropriate to the scope and
degree of those impacts, and reasonably enforceable (see 33 CFR
325.4(a)). Potential permit conditions addressing finfish mariculture
operations, such as amount of feed, pesticides, herbicides,
pharmaceuticals that can be released in project waters are beyond the
scope of the Corps' legal authority, because the Corps does not have
the authority regulate discharges of feed, pesticides, herbicides, and
pharmaceuticals into navigable waters, including federal waters on the
outer continental shelf. District engineers will review PCNs for
proposed NWP B activities, which will include information on the design
and size of the proposed structures. During
[[Page 2808]]
the evaluation of PCNs, district engineers consider the current
environmental setting and the ecological functions currently being
provided by aquatic resources in the vicinity of the proposed activity.
A couple of commenters said that notification to the U.S. Coast
Guard should be required for all proposed finfish mariculture projects
to ensure that structures are not placed within restricted zones,
shipping safety fairways, federal channels, traffic separation schemes
or within U.S. EPA- or Corps-designated open water dredged material
disposal areas. The Corps believes it is the project proponent's
responsibility to notify the U.S. Coast Guard of the proposed activity,
if such notification is required by law or regulations.
One commenter stated that the availability of an NWP for finfish
mariculture activities could be beneficial in promoting the business of
finfish mariculture in areas where it is currently difficult to gain
approval. The commenter added that growing seasons should be extended
to allow for more jobs and tax revenue. One commenter suggested
adopting location specific terms (freshwater, marine, offshore) and
dropping the term ``activity'' and instead use ``practice''
The Corps proposed this NWP to provide authorization under Section
10 of the Rivers and Harbors Act of 1899 for structures used for
finfish mariculture activities. Project proponents may be required to
obtain other federal, state, and local authorizations required by law
or regulation. This NWP does not have any limitations related to
growing seasons. The Corps believes it has provided sufficient
specificity regarding which types of waters this NWP can be used in
(i.e., marine and estuarine waters), including the use of term
``mariculture'' instead of the broader term ``aquaculture.'' The Corps'
authorization is limited to the installation of structures in navigable
waters of the United States, which is why the term ``activity'' is
used. The Corps does not regulate the operation of the finfish
mariculture facility during the production of finfish, and the
activities associated with production activities such as feeding,
handling, and administering antibiotics, therapeutics, and other
chemicals.
Regarding multi-trophic mariculture projects, one commenter stated
that the activity is still considered experimental, with potential for
adverse environmental impacts and a lack of proven success at
commercial sales, and would therefore not be suitable for authorization
under a NWP which should only be utilized for projects with predictable
outcomes. The Corps understands that multi-trophic mariculture
activities have been practiced in other countries (Largo et al. 2016,
Troell et al. 2009), so it is not an experimental approach. It is
intended to cultivate different tropic levels to help reduce nutrient
loads to surrounding waters.
Many commenters stated that applicants should be required to
clarify the species to be farmed as well as provide information on
broodstock source and quantity. Several commenters said that PCNs
should include project-specific details regarding configuration,
structures, techniques, proposed production quantities, densities,
spacing, and containment systems. One commenter recommended that the
PCN include a decommissioning plan.
The Corps has added text to this NWP to prohibit the cultivation of
aquatic nuisance species as defined in the Nonindigenous Aquatic
Nuisance Prevention and Control Act of 1990 and the cultivation of
nonindigenous species unless that species has been previously
cultivated in the waterbody. The Corps only regulates the structures
used for finfish mariculture activities, and their configuration in the
waterbody. The Corps does not have the authority to regulate the
techniques used to produce finfish, or how many finfish are produced
over a specific period of time. If the project proponent wants to cease
using the authorized structures for finfish mariculture activities,
those structures must be removed. General condition 13 requires, to the
maximum extent practicable, the removal of temporary structures from
navigable waters after their use has been discontinued. For permanent
structures, the Corps has added a provision to this NWP to require the
permittee to remove these structures from navigable waters of the
United States when those structures will no longer be used for finfish
mariculture activities or multi-trophic mariculture activities.
A few commenters said that all finfish mariculture activities
should require PCNs so that district engineers can evaluate consistency
with environmental standards, impacts to navigation, commerce, fishing,
and other resource use conflicts. One commenter suggested that the
applicant should be required to disclose in the PCN the intended use of
acoustic deterrent devices. Many commenters suggested that a higher
level of detail should be required for finfish mariculture activity
PCNs. A few commenters said the PCN should include a site analysis
incorporating available spatial information including depth, wave
climate, current velocity, substrate type, and proximity to any hard-
bottom habitats. A couple of commenters stated that applicants should
be required to provide detailed site maps, indicating the project
location in relation to ecologically important marine/estuarine areas.
One commenter said that applicants should be required to disclose the
proposed activity's proximity to other mariculture or commercial
fishing operations.
All activities authorized by this NWP require PCNs. The Corps does
not have the authority to regulate the use of acoustic deterrent
devices, so it would be inappropriate to require disclosure of the use
of such devices in PCNs for proposed NWP B activities. The information
requirements for PCNs in paragraph (b) of general condition 32 are
intended to provide the information necessary for the district engineer
to determine whether a proposed activity qualifies for NWP
authorization without an excessive amount of paperwork. The Corps
declines to require the suggested information for NWP B PCNs because it
is not needed to assist the district engineer in the determination of
NWP eligibility.
A few commenters said that the PCN should include a detailed
statement on avoidance and minimization measures regarding the
following impacts: Attraction and entanglement of wild fish, sharks,
mammals, and seabirds; effects of chemicals, antifoulants, feed, and
waste on water quality, habitat, and marine life; physical effects of
all structures on habitat and marine life; displacement, disruption and
risks to existing fishing activities; economic impacts to fishing
industries; and spatial conflicts with other ocean users. A few
commenters said that the applicant should be required to provide
prevention, monitoring, and response plans that address escapement of
cultured adults, progeny, and gametes; release of antimicrobials;
disease transmission to wild stocks; release of nutrients; chemical
pollution; structural failures; entanglement of fishing gear and marine
species; small vessel strikes; and marine debris.
The Corps does not agree that the suggested information is
necessary for PCNs for proposed NWP B activities to assist in the
district engineer's determination regarding whether the proposed
activity regulated by the Corps (i.e., the placement of structures in
navigable waters of the United States for finfish mariculture
activities) is expected to result in no more than
[[Page 2809]]
minimal individual and cumulative adverse environmental effects. Much
of the suggested information relates to operational aspects of finfish
mariculture operations, which the Corps does not have the authority to
regulate or control.
One commenter stated that under NWP review, there is potential for
an applicant to begin work within 45-days of submitting a PCN, even if
the permittee has not received a written response from the district
engineer. The commenter said that the 45-day default authorization
should not occur and that the proposed activity cannot proceed until
the district engineer issues a written verification.
After the Corps district receives a PCN, the prospective permittee
cannot begin the activity until either: (1) He or she is notified in
writing by the district engineer that the activity may proceed under
the NWP with any special conditions imposed by the district or division
engineer; or (2) 45 calendar days have passed from the district
engineer's receipt of the complete PCN and the prospective permittee
has not received written notice from the district or division engineer
(see paragraph (a) of general condition 32). If the permittee was
required to notify the Corps pursuant to general condition 18 that
listed species or designated critical habitat (or species proposed for
listing) might be affected or are in the vicinity of the activity, the
permittee cannot begin the activity until receiving written
notification from the Corps that there is ``no effect'' on listed
species or that any consultation required under Section 7 of the
Endangered Species Act has been completed. The Corps declines to add a
provision to NWP B to require the project proponent to receive written
authorization from the Corps prior to commencing the authorized
activity.
A couple of commenters expressed concern that structure placement
within estuarine habitats may result in reduced current, velocity,
altering circulation patterns, and consequently changing substrate
characteristics. One commenter stated that the addition of artificial
structures and moorings, and changes to seabed alter topography and
hydrodynamics. Some commenters voiced concerns regarding the use of
NWPs for emerging finfish mariculture activities, due to potential
impacts on water quality, habitat, and wild species, requesting that
activities in the area be reviewed through the individual permit
process.
The Corps acknowledges that structures placed in navigable waters
may reduce water velocities to some degree and alter sediment transport
and coastal erosion and deposition processes. District engineers will
review proposed NWP B activities and determine whether it minimizes the
impacts where practicable pursuant to general condition 23. Division
and district engineers have discretionary authority to modify, suspend,
or revoke NWP authorizations to further condition or restrict the
applicability of an NWP when they have concerns for any factor of the
public interest (see 33 CFR 330.1(d)).
Many commenters said that construction of finfish mariculture
operations should be prohibited within a specific proximity to marine
protected areas, submerged aquatic vegetation, reef communities,
habitats with significant important to existing aquatic communities,
migration pathways, at specific water depths, and those areas subject
to chronic oxygen and nitrogen depletion. A few commenters stated that
finfish mariculture activities should be prohibited from areas
identified as being prone to hypoxia or otherwise ecologically
sensitive. Several commenters said that increases in finfish
mariculture projects would have the potential to damage the commercial
fishing industry by either decreasing the need for wild fishing or by
causing adverse impacts to the health and habitat of wild fished
species. One commenter stated that finfish mariculture could have the
potential to adversely impact local economies by pushing out
responsible, small-scale seafood producers and crop growers.
Several commenters expressed concern with spatial conflicts,
specifically with fishing, fishery research cruises, and long-term
ocean monitoring stations which occupy much of state and federal
waters. Additional potential conflicts identified by commenters
included gear entanglement, displacement from traditional fishing
areas, navigational safety, and income loss. Many commenters raised
concerns about project siting requirements, with one commenter
suggesting that the Corps should be required to perform a spatial
siting analysis prior to issuance of an NWP verification to ensure the
proposed activity does not interfere with existing fisheries
operations, research projects, or affect federal marine protected
areas, and essential fish habitat.
Impacts regarding navigation are localized and therefore it is more
efficient for district engineers to evaluate potential impacts in their
review of PCNs. Finfish mariculture operators have, absent any
potential exceptions, the same rights to use navigable waters as other
users such as fishers, recreational users, researchers, and commercial
users as long as they obtain all required federal, state, and local
authorizations. In addition to the authorization under Section 10 of
the Rivers and Harbors Act of 1899, finfish mariculture operators may
be required to obtain other federal, state, or local authorizations.
The Corps does not have the authority to conduct spatial planning for
finfish mariculture activities. If the district engineer determines a
proposed NWP B activity may adversely affect essential fish habitat, he
or she will conduct essential fish habitat consultation with NMFS.
Activities in marine protected areas may be require authorizations from
the federal or state agency that has management responsibilities for
those areas.
A couple of commenters stated that structures could cause
interference with access to treaty protected fishing grounds for tribal
fisherman. Several commenters said that these activities could impact
recreational activities by closing off areas of navigable waters that
would otherwise be used for boating, fishing, tourism, and other water-
related activities. A few commenters stated that finfish mariculture
activities would close off or privatize areas currently used by the
commercial fishing industry. One commenter stated that finfish
mariculture activities could have the potential to adversely impact
local economies by pushing out responsible, small-scale seafood
producers and crop growers.
Activities authorized by NWP B must comply with general condition
17, tribal rights. District engineers will review PCNs for proposed NWP
B activities and assess potential impacts to navigation, including
boating, fishing, tourism, and other water-related activities that use
those navigable waters. There are a variety of activities (e.g., piers,
port facilities, marine hydrokinetic devices) authorized by the Corps
in navigable waters under its section 10 authorities that preclude or
restrict use by others. The potential economic impacts of finfish
mariculture activities on local businesses and residents is outside the
Corps' control and responsibility.
A couple of commenters said that finfish mariculture activities
should raise farmed species that live in or adjacent to the body of
water, to minimize the introduction of disease from species relocated
from other regions. Another commenter suggested using only species
native to the ecosystem where the finfish mariculture activity is
located. One commenter requested the establishment of
[[Page 2810]]
exclusion zones, using assessments that consider not just the immediate
area, but potential impacts to nearby waters as well. One commenter
said that by requiring siting of finfish mariculture outside of known
migratory pathways, predation from wild species may be minimized,
entanglements may be reduced, and potential fish spills from net/cage
damage by predatory species may also be reduced. One commenter
suggested siting finfish mariculture activities in deep, open waters to
minimize the effects of nutrient and sediment dispersal from the
project site, which may cause increases in nitrogen and phosphorous
levels, as well as increases in phytoplankton and algae. Several
commenters said that finfish mariculture activities should not be
authorized in estuarine waters to minimize adverse effects to water
quality. A few commenters stated that the PCN review process does not
provide for adequate planning and would eliminate project-specific
public notice and comment period that would facilitate responsible site
selection.
The Corps does not have the authority to specify which species are
cultivated at a finfish mariculture structure authorized by the Corps
under section 10 of the Rivers and Harbors Act of 1899. In addition,
the Corps does not have the authority to establish mariculture
exclusion zones in navigable waters. Siting requirements on finfish
mariculture activities may be imposed by other federal, state, or local
government agencies.
Many commenters expressed concerns regarding potential impacts to
existing habitat, specifically coral reef systems, mangroves, and
submerged aquatic vegetation that could be caused by increases in
nutrient and sediment dispersal from the finfish mariculture operation.
One commenter said that net pen structures and their associated
anchoring systems have the potential to increase available habitat,
supporting biodiversity, similar to engineered artificial reefs. In
addition, this commenter said that the structures would prevent
trawling of the benthic ecosystem within the footprint of the facility,
further protecting species.
When reviewing PCNs for proposed NWP B activities, district
engineers will evaluate potential impacts on habitats in the vicinity
of the proposed finfish mariculture structures. The Corps acknowledges
that finfish mariculture structures can provide structural habitat that
benefits some aquatic species, as well as providing some refuge from
predators and fishers.
Several commenters expressed concerned with the potential
entanglement of wild fish and marine mammal species, stating that NWP
review would not allow for adequate evaluation for potential impacts.
One commenter discussed the potential for illegal extermination of
predator species such as sea lions by operators of finfish mariculture
facilities. A few commenters raised concerns regarding the use of
acoustic deterrent devices, which they said are not consistently useful
and have been known to cause deleterious impacts to non-target species.
Other commenters stated that these activities would have the potential
to attract and concentrate predators, which may lead to entanglements
or vessel strikes. One commenter said that risks and impacts to
protected species are minimized by existing federal requirements for
operations, including the use of improved technologies and regular
maintenance, such as line-tightening, which has been shown to prevent
accidental entanglement. A few commenters stated that this NWP must
prohibit gear types known to cause harm to marine species. One
commenter said that finfish mariculture structures should be removed
from waters during peak seasons for protected species.
If the district engineer determines that a proposed finfish
mariculture activities may affect listed species or designated critical
habitat, he or she will conduct ESA section 7 consultation with the
U.S. FWS and/or NMFS. The operator of the finfish mariculture facility
may also need to obtain authorization under the Marine Mammal
Protection Act. The ESA section 7 consultation may result in permit
conditions added to the NWP authorization to minimize the risk of
entanglement of listed species. The Corps does not have the authority
to regulate the management of predator species at a finfish mariculture
facility, or the use of acoustic deterrent devices. The use of acoustic
deterrent devices would be addressed through the ESA section 7
consultation process and/or the Marine Mammal Protection Act
authorization process, if applicable.
One commenter said that finfish mariculture operations should only
be stocked with eggs, larvae, or juveniles from pen-raised lineages, in
order to avoid the need for wild capture. Another commenter stated that
the cultivated species should have the same indigenous genetic stock as
individuals of the species in the waters where the proposed finfish
mariculture activity is located. The Corps does not have the authority
to impose requirements on the stocking of finfish mariculture
facilities, or which genetic stocks are cultivated.
Many commenters stated concerns with the potential for accidental
fish escapements by individual species because the introduction of non-
native species may spread pathogens and parasites to wild species,
increase competition to at-risk communities, and cause genetic
degradation among existing fish populations. Several commenters
discussed the 2017 escape of over 200,000 non-native Atlantic salmon in
the Puget Sound as a result of finfish mariculture operations, with
some commenters requesting that these activities require individual
permits, and other commenters stating that regional conditions should
be implemented to ensure structural integrity of facility structure and
prevent escape recurrences. One commenter said that although the Corps
lacks the authority to regulate finfish escapes, it can require
structures installed in navigable waters to be constructed to a
standard where escape risks can be mitigated. One commenter stated that
applicants should be required to report escape events to the Corps and
that the Corps should maintain a database to monitor events and better
prevent them in the future. A few commenters said that a universal
standard should be developed that specifies requirements for the
proposed finfish mariculture facilities and related features that would
meet challenges posed by severe weather, and prevent potential
escapements.
The Corps does not have legal authority to regulate the potential
escapement of cultivated finfish. The Corps acknowledges that finfish
mariculture activities have the potential to facilitate the spread of
pathogens and parasites, but the Corps does not have the authority to
regulate or control those occurrences. General condition 14 requires
proper maintenance of authorized structures and fills. The project
proponent is responsible for designing and constructing the finfish
mariculture structures so that they have an appropriate degree of
structural integrity. Since the Corps does not have the authority to
address potential fish escapes, there would be no useful purpose served
by requiring the operator to report escapes to the Corps, or for the
Corps to maintain a database to track escape events.
One commenter said that all mariculture operations should be
considered point sources under the Clean Water Act and be required to
obtain discharge permits. This commenter also said that routine disease
testing and other water quality monitoring should also be mandated. One
stated that effects to water quality within the local environment from
other sources would have the potential to
[[Page 2811]]
cause impacts to cultured species and subsequently economic returns of
the finfish farm, suggesting that maintenance of the facility would be
in the best interest of the operation and thus encourages management
operations that support the local environment. Some commenters said
that finfish mariculture activities can cause changes to benthic
community composition beneath and adjacent to structures because of
excess feed, feces, and antifoulant accumulation. A couple of
commenters stated that finfish mariculture projects should be held to
the same regional water quality standard as offshore seafood
processors. Several commenters expressed concern with the ingredients
utilized in fish feed, which one commenter said often contains toxic
heavy metals like cadmium and zinc and recommended that feed
formulation and efficiencies be standardized and managed in order to
lessen adverse environmental impacts. Another commenter suggested that
finfish mariculture operators should be required to publish reports
with the complete traceability of all mariculture feed products. One
commenter asserted that permittees be required to provide proof that
the finfish mariculture operations would not contribute to hypoxia in
receiving waters.
Some finfish mariculture operations may require authorization under
Section 402 of the Clean Water Act for discharges from finfish
mariculture operations. Section 402 of the Clean Water Act is
administered by the U.S. EPA or states with approved programs. The
Corps lacks the authority to require disease testing and water quality
monitoring. Water quality monitoring may be required by states in
estuaries and the territorial seas. The Corps acknowledges that finfish
mariculture activities can have effects on benthic communities. The
Corps does not have the authority to regulate the production of finfish
after the mariculture facility is constructed.
Several commenters expressed concerns about the potential effects
of the use of antimicrobials, pesticides, and anti-foulants, and the
introduction of excess feed and fish waste in project waters. These
commenters stated that use of these materials could lead to degradation
of water quality, risking public health, and increase organic nutrient
loads leading to eutrophication, causing widespread damage to wildlife.
A few commenters said that industrial finfish mariculture operations
may cause adverse impacts to public health, as the antibiotics,
pesticides, and other chemicals that are heavily used to prevent
disease and parasites in farmed species could accumulate in fish
tissues to be consumed by the public. One commenter stated that these
issues have influenced other countries like Canada, Argentina and
Denmark, to move away from industrial finfish mariculture.
The Corps does not have the authority to regulate the use of
antimicrobials, antibiotics, pesticides, anti-foulants and other
chemicals, how feed is provided to the cultivated finfish, or the
composition of that feed and its potential effects on water quality.
Water quality concerns may be addressed through state or federal water
quality standards under the Clean Water Act, or state laws.
A couple of commenters said that ESA section 7 consultation should
be mandatory for all proposed finfish activities and that all
applicants should be required to obtain an incidental take permits for
potential effects to listed species. One commenter stated that NOAA
would be the appropriate agency to provide expertise in reviewing and
assigning specific permit terms in regard to site selection, conflicts
between aquaculture projects, marine resources, other ocean users, and
wild-capture fisheries. A couple of commenters said that individual
finfish mariculture projects should be coordinated with state natural
resource agencies to identify regional and site-specific concerns,
needs analyses, and project-specific conditions.
All activities authorized by this NWP require PCNs. If the district
engineer reviews a PCNs and determines that any proposed activity may
affect listed species or designated critical habitat, he or she will
conduct ESA section 7 with the U.S. FWS and/or NMFS as appropriate.
Incidental take permits are issued under Section 10(a)(1)(B) of the
ESA, not section 7(a)(2). The Corps declines to add a provision to this
NWP requiring coordination with state natural resource agency, whose
legal authorities are highly variable and generally do not apply in
federal waters.
One commenter questioned the Corps' reliance on general condition
23 to minimize project impacts. Another commenter said that all NWP B
applicants should be required to provide a mitigation plan. Several
commenters voiced concern over the risk for breakage of anchored
mooring systems for finfish mariculture structures during significant
weather events, which increases risks to navigational safety and marine
debris. Additional concerns regarding marine debris were voiced by
another commenter, who suggested that operators may dispose of solid
waste into waters rather than through appropriate methods. One
commenter recommended requiring agency coordination for proposed NWP B
activities under paragraph (d) of general condition 32.
General condition 23 provides the mitigation requirements for the
NWPs. District engineers can require the project proponent to submit a
mitigation plan if, after reviewing a PCN, the district engineer
determines that mitigation is necessary to ensure the authorized
activity will cause no more than minimal individual and cumulative
adverse environmental effects. The project proponent is responsible for
designing and constructing the finfish mariculture facility so that it
complies with applicable engineering standards, and will maintain
structural integrity within the appropriate parameters of sea and
weather conditions, and potential predatory behavior by large
vertebrates. The Corps does not believe that agency coordination under
paragraph (d) of this NWP is necessary for these activities.
One commenter asserted that the draft decision document for NWP B
did not meet NEPA requirements, stated that it lacked adequate
discussion on purpose and need, which the public needs for
consideration of the scope of reasonable alternatives. One commenter
said that an environmental impact statement should be required for
approval of NWP B, claiming that the Corps failed to adequately discuss
how potentially significant impacts will be mitigated below the level
of significance in the draft decision document. One commenter stated
the Corps failed to address potential adverse cumulative impacts at a
regional level where specific locations recently identified by NOAA are
more likely to be impacted.
The national decision document for this NWP was revised to address
the requirements for environmental assessments in the Council on
Environmental Quality's NEPA regulations that were published in the
Federal Register as a final rule on July 16, 2020 (85 FR 43304). A
section on purpose and need was added to the national decision
document. The Corps made a finding of no significant impact. Therefore,
an environmental impact statement is not required for the issuance of
this NWP. The national decision document considers the cumulative
effects expected to occur as this NWP is used during the 5-year period
it is anticipated to be in effect, and it is a national analysis since
the geographic scope of the national decision document is the United
States. Division engineers consider cumulative effects of NWP
activities on a regional basis.
[[Page 2812]]
One commenter stated that the minimal effect determination is
conclusory, as no quantitative impact limits, general conditions, or
regional conditions have been specified and the impact section did not
provide discussion on any foreseeable or unknown impacts. One commenter
said that the Corps' minimal effects determination should provide
estimates for the anticipated size of mariculture operations to be
permitted under NWP B and potential impacts of those operations based
on known impacts of net pen finfish mariculture.
The Corps did not provide a minimal effects determination in the
draft national decision document, so the commenter cannot say that it
is conclusory. The NWPs are not required to have quantitative impact
limits, and the proposed NWP general conditions were provided in the
proposed rule. The regional conditions have not been finalized by
division engineers. The draft decision document discusses reasonably
foreseeable impacts. The Corps is not required to consider speculative
impacts. The Corps did provide estimates of the impacts that may occur
during the 5-year period this NWP is anticipated to be in effect.
Proposed NWP B is issued as NWP 56, with the modifications
discussed above.
(15) NWP 57. Electric Utility Line and Telecommunications Activities
The Corps proposed this new NWP as NWP C, to authorize discharges
of dredged or fill material into waters of the United States, and
structures and work in navigable waters of the United States, for
electric utility line and telecommunications activities.
Many commenters expressed support for the proposal to issue a
separate NWP for electric utility line and telecommunications
activities. They said that the creation of this new NWP for electric
utilities represents a tailored approach to regulated industries and
effectively addresses differences in how the various types of utilities
are constructed, installed, maintained, and removed. Many commenters
supported retaining the basic structure of the 2017 NWP 12 for proposed
new NWP C, as well as continuing the longstanding definition of
``single and complete'' project, providing authorization for temporary
structures, fills, and work, and imposing the same acreage limits. One
commenter supports the Corps' proposal to include the list of
structures and fills in NWP C, including utility lines, substations,
foundations for towers poles and anchors, access roads, temporary
structures, fill, and work for remediation of drilling fluid returns
from horizontal directional drilling, and temporary structures, fill,
and work including temporary mats for utility line and
telecommunications activities.
The Corps is issuing NWP C to authorize discharges of dredged or
fill material into waters of the United States and structures and work
in navigable waters of the United States for electric utility line and
telecommunications activities. For the text of NWP C, the Corps has
retained a structure similar to the structure of NWPs 12 and D, and
there are some differences in the specific text of NWPs 12, C, and D to
address differences in utility line sectors. The Corps is also
retaining the regulatory approach for authorizing single and complete
linear projects, where each separate and distant crossing of waters of
the United States may be covered by its own NWP authorization. The
corps is also retaining the \1/2\-acre limit for each separate and
distant crossing of waters of the United States and for the
construction, maintenance, or expansion of substations for electric
utility and telecommunications lines. The Corps is also including the
authorization of temporary structures and fills, as well as DA
authorization for remediation activities requiring DA authorization
that may be needed to address inadvertent returns of drilling fluids,
consistent with NWPs 12 and D.
Many commenters stated that they expect court challenges to oil and
gas pipeline activities to continue, and therefore support the issuance
of a separate NWP for electric utility line and telecommunications
activities. By creating a separate NWP for these activities, it is the
hope of these commenters that these electric infrastructure activities
will not be disrupted by future NWP 12 litigation.
The Corps acknowledges that the issuance of NWP C can help reduce
regulatory uncertainty for entities that construct and maintain
electric utility lines and telecommunications lines. Past litigation on
NWP 12, especially for oil or natural gas pipelines, has caused
concerns about the availability of NWP authorization for electric
utility lines and telecommunication lines and their ability to serve
people living in the United States.
Several commenters noted that proposed NWP C is important as the
scale of electrical energy generation from renewable energy sources
increases. These commenters said there will be a need for additional
electric transmission facilities to convey the electricity from the
generation facilities to the end users. Several commenters stated that
proposed NWP C will satisfy Section 404(e) of the Clean Water Act by
authorizing activities that have no more than minimal adverse
environmental effects, while continuing to allow for timely and
efficient authorization of these activities. These commenters said that
the techniques used to construct, maintain, and repair most electric
transmission lines generally result in fewer impacts to waters of the
United States compared to the techniques used to construct other types
of utility lines. Several commenters requested that the Corps not issue
proposed NWP C, stating that the activities authorized by this NWP
would cause significant adverse impacts in violation of Section 404(e)
of the Clean Water Act. These commenters said individual permits should
be required for these activities.
The Corps also appreciates the potential for new NWP C to support
electric energy generation from renewable energy generation facilities,
including activities authorized by NWPs 51 and 52. The Corps believes
that the conditions for NWP C, including the reviews of PCNs for
certain activities authorized by NWP C and the ability of division and
district engineers to modify, suspend, and revoke NWP C authorizations,
will help ensure that activities authorized by NWP C result in no more
than minimal individual and cumulative adverse environmental effects.
A few commenters noted that the issuance of NWP C would allow the
Corps to incorporate industry-specific standards, appropriate regional
conditions, and best management practices tailored to each utility line
NWP. A few commenters said that proposed NWP C is important because the
process of applying for and obtaining an individual permit is time
consuming, expensive, and subject to regulatory uncertainty. These
commenters said that increased costs and burdens that result from the
individual permitting process can affect not only the members, but the
amount of costs that are passed on to consumers and indirectly borne by
the rural public. One commenter stated that the availability of NWPs
authorizing the construction, maintenance, repair, and removal of
utility lines and associated facilities is essential to the expansion
of necessary infrastructure to remote areas in the United States.
In this final rule, the Corps discusses suggestions for best
management practices and national standards that commenters provided in
response to the 2020 Proposal. The Corps acknowledges that the issuance
of NWP C will further the objective of the NWP program,
[[Page 2813]]
which is to regulate with little, if any, delay or paperwork certain
activities having minimal impacts (33 CFR 330.1(d)).
One commenter stated that fiber optic lines should be specifically
added to the definition of electric utility line and telecommunication
line. One commenter recommended retaining the following provision in
proposed NWP C: ``there must be no change in pre-construction contours
of waters of the United States.'' One commenter said that the integrity
of power lines in their service area could be severely compromised if
vegetation management must be stopped while they obtain individual
permits for this necessary and routine activity. Vegetation along
electric utility rights of way must be maintained to prevent trees or
other vegetation from bringing down power lines and, during dry
conditions, preventing power lines from contributing to wildfires.
The Corps has added fiber optic lines to the definition of electric
utility line and telecommunication line. The requirement that NWP C
activities associated with the construction, maintenance, repair, and
removal of electric utility lines and telecommunications lines result
in no change in pre-construction contours in waters of the United
States do not compromise vegetation management because most vegetation
management is conducted above the soil surface. In situations where
vegetation management involves the removal of plants and their roots,
the project proponent can regrade the soil surface so that there are no
changes in pre-construction contours of waters of the United States,
including jurisdictional wetlands. The Corps acknowledges that
vegetation management is important for safe, reliable operation of
electric utility lines and telecommunications lines, and for managing
fire risks. However, the Corps does not have the legal authority to
require vegetation management activities to manage fire risks. State
and local governments may possess that authority.
A few commenters recommended removal of the following sentence from
the preamble to the proposed rule: ``The wooden poles used for overhead
electric transmission lines can be up to 27 inches in diameter, and
these poles are usually inserted into the soil surface by digging a
hole, with some soil disturbance in the vicinity of the installed
pole.'' These commenters said that utility poles are specified based on
class and height, not diameter. In addition, these commenters noted
that round treated wood utility poles can be greater than 27 inches in
diameter. Lastly, these commenters said that treated wood utility poles
can be provided not only as ``round poles'', but also as ``laminated
rectangular poles.'' These commenters recommended adding the following
sentence to the final rule: ``The wooden poles used for overhead
electric transmission lines can be up to 40 inches in diameter or up to
90 inches on any side for rectangular poles.''
The Corps cannot remove sentences from documents that have already
been published in the Federal Register, and it sees no need to remove
this text because it only served as background information for the
proposed rule, including the proposal to issue three separate NWPs for
different sectors of utility line activities. The Corps acknowledges
that this sentence is incomplete, and appreciates the additional
clarification provided by the commenter.
A few commenters noted that, although the preamble recognizes the
wide array of structure types for utility lines, the language of
proposed NWP C appears to assume a limited design configuration for
structures to support aerial transmission lines. These commenters said
that the requirement for separate footings for each tower leg
incorrectly suggests that such lines only utilize lattice tower type
structures with multiple legs per structure, which is not the case.
Therefore, these commenters recommended that the Corps eliminate this
language from the final NWP C to accurately reflect the wide array of
structure types that are used to support aerial utility and
telecommunication lines. One commenter recommended revising the text as
follows: ``This NWP authorizes the construction or maintenance of
foundations for overhead electric utility line or telecommunication
line structures, towers, poles, and anchors in all waters of the United
States, provided the foundations are the minimum size necessary.''
The text of NWP C provides substantial flexibility in authorizing
discharges of dredged or fill material into waters of the United States
associated with the installation of structures used to support aerial
transmission lines. The text of the NWP acknowledges that single poles
may be used for overhead transmission lines, and there is flexibility
for authorizing discharges of dredged or fill material into waters of
the United States for footings that support other types of structures
used for aerial transmission lines, including lattice tower types
structures. For foundations for overhead electric utility line or
telecommunication line towers, poles, and anchors, the Corps is
retaining the text of the NWP as proposed.
One commenter supports the Corps' proposal to use the \1/2\-acre
limit in proposed NWP C. One commenter stated that it remains unclear
when associated facilities are authorized by multiple NWPs, whether the
\1/2\-acre limit will be applied to multiple NWPs or if only one NWP
will be selected to authorize the associated facilities.
The Corps has retained the \1/2\-acre limit for losses of waters of
the United States for each single and complete project authorized by
NWP C. General condition 28 addresses the use of multiple NWPs to
authorize a single and complete project and that general condition
applies to utility line crossings that may involve different types of
utility lines authorized by NWPs 12, C, and/or D, where the acreage
limit for each single and complete project continues to be \1/2\-acre.
One commenter objected to the inclusion of substation facilities in
this NWP, because substations can usually be constructed in uplands.
One commenter said the proposed text for foundations for overhead
electric utility line or telecommunications lines towers, poles, and
anchors should be revised.
The Corps is retaining substations in this NWP because there are
likely circumstances where it is not feasible or practicable to site a
substation in uplands. This NWP provides DA authorization for
discharges of dredged or fill material into waters of the United States
for the construction, maintenance, or expansion of electric utility
line and telecommunications substations as long as the loss of waters
of the United States does not exceed \1/2\-acre.
One commenter stated that the Corps should end the practice of
considering timber and other mats used for temporary access and
construction as resulting in discharges of dredged or fill material
into waters of the United States and as part of the filled area for the
PCN thresholds. Some Corps districts count matting toward the PCN
threshold for permittees, requiring permittees to submit a PCN if the
discharge will result in the loss of greater than \1/10\-acre of waters
of the United States.
The Corps believes that the decision on whether timber mats or mats
constructed of other materials that are used during construction,
maintenance, repair, or removal of electric utility lines and
telecommunication lines result in discharges of dredged or fill
material
[[Page 2814]]
into waters of the United States and thus require DA authorization is
more appropriately made by district engineers on a case-by-case basis.
Such decisions should be made by district engineers after considering
the definitions of ``discharge of dredged material'' and ``discharge of
fill material'' at 33 CFR 323.2(d) and (f). The use of temporary
matting does not constitute a ``loss of waters of the United States''
or count towards the \1/10\-acre PCN threshold for losses of waters of
the United States as long as the timber matting is removed after
completion of the authorized work and the affected area restored to
pre-construction elevations.
A few commenters stated that applicants should have to produce
containment and clean up contingency plans as a best management
practice to address inadvertent returns of drilling fluids during
horizontal directional drilling activities. The Corps does not have the
authority to require project proponents to develop containment and
contingency plans for horizontal directional drilling activities that
do not involve discharges of dredged or fill material into waters of
the United State or cross navigable waters and require section 10
authorization. The NWP authorizes regulated activities that may be
necessary to remediate inadvertent returns of drilling fluids to
provide timely responses to such events and help reduce potential
adverse effects to the aquatic environment that may occur as a result
of these inadvertent returns.
Several commenters supported the two PCN thresholds for proposed
NWP C. They stated that limiting the PCN requirements for this NWP to
these two PCN thresholds will reduce burdens on the regulated public,
simplify NWP C, eliminate redundancy, and focus the PCN requirements on
activities that have a substantive potential to result in more than
minimal adverse environmental effects. One commenter stated that the
proposed PCN requirements add an administrative burden to the Corps and
reduce certainty for projects. Many commenters opposed having only two
PCN thresholds and requested that NWP C have the same seven PCN
thresholds as the 2017 NWP 12.
In the 2020 Proposal the Corps proposed two PCN thresholds for this
NWP: (1) For activities that require section 10 authorization, and (2)
for discharges that result in the loss of greater than \1/10\-acre of
waters of the United States. In response to the proposed rule, the
Corps received comments recommending the addition of other PCN
thresholds that were removed from NWP. For summaries of the comments on
the five PCN thresholds that were in the 2017 NWP 12 but removed from
the 2021 NWP 12, and the Corps' responses to those comments, interested
persons should read the section in this final rule on the reissuance of
NWP 12.
One commenter supported the proposal to require PCNs for losses of
greater than \1/10\-acre of waters of the United States. One commenter
recommended requiring PCNs for mechanized land clearing of forested
wetlands in the electric utility line right-of-way where greater than
\1/10\-acre of forested wetland is subjected to mechanized land
clearing, instead of requiring PCNs for any amount of mechanized land
clearing in forested wetlands. One commenter asked why activities that
result in changes in pre-construction contours, but do not result in
permanent losses of waters of the United States cannot be permitted by
NWP C while activities that do not result in a change to pre-
construction contours, but result in up to \1/10\-acre of permanent
loss of waters of the United States can be permitted by this NWP.
The Corps did not propose to require PCNs for discharges of dredged
or fill material into waters of the United States associated with
mechanized land clearing of forested wetlands in the utility line right
of way. If, for a proposed electric utility line or telecommunications
line, the applicant proposes to conduct mechanized land clearing of
forested wetlands in the right-of-way for the electric utility line or
telecommunications line, a PCN is required if the project proponent
will be unable to restore the disturbed wetlands to pre-construction
elevations and the activity involves a discharge of dredged or fill
material that results in the loss of greater than \1/10\-acre of waters
of the United States. Nationwide permit C authorizes discharges of
dredged or fill material into waters of the United States that result
in permanent losses of waters the United States, as long as that loss
does not exceed \1/2\-acre for each single and complete project.
One commenter opposed the requirement to submit a PCN for
activities that require authorization under Section 10 of the Rivers
and Harbors Act, regardless of the amount of loss. The Corps has
retained this PCN threshold so that district engineers have the
opportunity to review these activities and ensure that the authorized
activities cause no more than minimal adverse effects to navigation.
Several commenters objected to allowing multiple segments of the
same pipeline to qualify for NWP authorization, stating it is a
violation of Section 404(e) of the Clean Water Act, the National
Environmental Policy Act, the Endangered Species Act, and other legal
requirements for rigorous and transparent environmental reviews and
safeguards. A few commenters noted that while electric and
telecommunication lines do not pose the same risks of spills and leaks
as oil and gas pipelines, they still allow for greater than minimal
impacts by authorizing large electric lines and telecommunications
lines under the guise of ``single and complete projects.''
Considering separate and distant crossings of waters of the United
States to be linear projects that can be authorized by separate NWPs is
a long-standing practice that has been codified in the Corps
regulations at 33 CFR 330.2(i) since 1991 (see 56 FR 59110). This
practice does not violate Section 404(e) of the Clean Water Act, NEPA,
or the ESA. The Corps complies with NEPA when it issues the national
decision document for the issuance of an NWP, because that decision
document includes an environmental assessment. Activities authorized by
NWP C and other NWPs must comply with general condition 18, endangered
species. The Corps acknowledges that some spills or leaks may occur
from equipment associated with electric utility lines and
telecommunications lines, including equipment at substations, but the
Corps does not have the authority to regulate such spills or leaks.
A few commenters stated that is that it is unclear how the Corps
will evaluate what constitutes a ``project'' under these NWPs for the
purposes of determining whether a project exceeds the \1/2\-acre limit
or results in a loss of more than \1/10\-acre in order to trigger the
requirement for an individual permit. A few commenters requested
additional details regarding what measures will be used to ensure that
projects under these NWPs are not improperly divided into smaller
sections to avoid an individual permit requirement. Several commenters
state that the ``single and complete project'' concept should not apply
to the installation of new electric utility line and telecommunication
activities. Some commenters said a new electric utility line or
telecommunications line should be subject to analysis under NEPA for
the entire project, including a cumulative review of all temporary and
permanent impacts to waters of the United States from the utility line
crossings, access roads, substations, temporary work pads, etc.
The Corps has long-standing practice and experience evaluating
single and
[[Page 2815]]
complete projects when applying the \1/2\-acre limit and the \1/10\-
acre PCN threshold for losses of waters of the United States. District
engineers have the discretion to determine which regulated activities
constitute ``single and complete linear projects'' and ``single and
complete non-linear projects'' in accordance with the Corps'
regulations and the definitions in Section F of these NWPs. When an NWP
C activity requires a PCN, paragraph (b)(4)(i) of general condition 32
requires the applicant to include in the PCN and any other NWP(s),
regional general permit(s), or individual permit(s) used or intended to
be used to authorize any part of the proposed project or any related
activity, including other separate and distant crossings for linear
projects that require Department of the Army authorization but do not
require pre-construction notification. Furthermore, paragraph
(b)(4)(ii) of general condition 32 requires the applicant to include in
the PCN the quantity of anticipated losses of wetlands, other special
aquatic sites, and other waters for each single and complete crossing
of those wetlands, other special aquatic sites, and other waters
(including those single and complete crossings authorized by NWPs but
do not require PCNs). The district engineer uses this information to
evaluate the cumulative adverse environmental effects of the proposed
linear project. Activities authorized by NWP do not require additional
NEPA compliance, because the Corps satisfies the requirements of NEPA
when it issues the national decision documents for the NWPs.
One commenter stated that a PCN should be required for any new or
expanded electric utility line project, and there needs to be an
overall limit in acreage of waters of the United States lost as a
result of activities authorized by this NWP. A few commenters said that
proposed NWP C should include the 250-mile PCN threshold proposed for
NWP 12. These commenters asserted that not adding the 250-mile PCN
threshold allows for very large projects to be built without a PCN and,
therefore, bypass other federal requirements that are triggered by the
section 404 process such as the requirements of Section 7 of the
Endangered Species Act and Section 106 of the National Historic
Preservation Act. One commenter asked whether temporary impacts and
impacts that involve conversion from one wetland type to another (e.g.,
forested wetland to herbaceous) are counted as part of the \1/10\-acre
PCN notification threshold. These commenters recommended revising the
definition of ``loss of waters of the United States'' to include
permanent conversion of wetland types.
The Corps does not agree that PCNs should be required for any
expansion of electric utility line projects. The information required
by paragraphs (b)(4)(i) and (ii) of general condition 32 provides the
Corps with information similar to the 250-mile PCN threshold that was
added to NWP 12, but the Corps does not believe that the 250-mile PCN
threshold is necessary for NWP C because it authorizes projects with
typically smaller footprints of discharges of dredged or fill material.
Activities authorized by NWP C must comply with general condition 18,
endangered species, and general condition 20, historic properties.
Temporary impacts are not considered a ``loss of waters of the United
States.'' A permanent conversion of wetland type is generally not
considered a ``loss of waters of the United States'' because the
affected area is still a wetland, and vegetation management activities
such as cutting and mowing vegetation or using herbicides are not
regulated by the Corps under its permitting authorities.
One commenter stated that Corps districts should maintain
consistency with the number of thresholds that trigger the need for a
PCNs expressed in the proposed rule. This commenter noted that some
Corps districts have already proposed regional conditions that will
undercut the changes in the proposed rule. This commenter said that
differences in PCN thresholds across Corps districts could complicate
NWP C by increasing confusion and inefficiencies.
Division engineers have the authority to approve regional
conditions for this NWP based on the characteristics and other factors
regarding the ecosystems in their respective regions, including
regional conditions that add PCN thresholds. Division engineers can add
regional conditions to replace PCN thresholds that were removed from an
NWP, if the division engineer determines that PCN threshold is
necessary to ensure that the activity has no more than minimal or
cumulative adverse environmental effects. Regional conditions are an
important mechanism for tailoring the NWP program to address specific
resource concerns in a particular geographic area.
Several commenters opposed including Note 2 in NWP C. These
commenters said that Note 2 is inconsistent with the requirements of
Section 404(e) of the Clean Water Act and that it would allow
activities that have more than minimal adverse environmental effects to
proceed. One commenter said that proposed Note 2 would explicitly allow
the cobbling together of multiple NWPs to authorize high impact
pipelines and associated infrastructure that have greater potential for
harmful spills, leaks, and the discharges that accompany them. As
discussed above in response to comments on the Corps' definition of
``single and complete project'' at 33 CFR 330.2(i), Note 2 is consist
with that regulation and this long-standing practice.
One commenter recommended clarifying and rephrasing the following
sentence found in Note 3: ``Aerial electric utility lines or
telecommunication lines crossing navigable waters of the United States
(which are defined at 33 CFR part 329) must comply with the applicable
minimum clearances specified in 33 CFR 322.5(i). The Corps believes
that no additional clarification is necessary for Note 3 because it
only points to a specific provision of the Corps' regulations to serve
as a reminder to project proponents that want to construct electric
utility lines or telecommunications lines over navigable waters of the
United States.
A few commenters recommended including the term ``and other
temporary structures'' in the text of Note 4. These commenters
suggested changing Note 4 to state that access roads and other
temporary structures such as work pads, temporary utility poles, and
pulling and tension pads, used for both construction and maintenance
may be authorized, provided they meet the terms and conditions of this
NWP. Note 4 specifically addresses access roads, and the Corps believes
it would be inappropriate to address other temporary structures in this
note. Temporary structures are addressed in a separate paragraph in the
text of NWP C.
A few commenters recommended that if the Corps includes specific
best management practices (BMPs) in the final NWP C, it should indicate
that the BMPs should be implemented ``where appropriate and practical''
and recognize that implementation of certain BMPs may not be required
in all circumstances. These commenters noted that there are a wide
range of minimization, avoidance, and management measures deployed to
reduce impacts to aquatic environments, some are unique to the electric
and telecommunication utility lines. However, it would be difficult to
include many of these BMPs as national requirements for all uses of NWP
C because their implementation, while
[[Page 2816]]
frequent, is site-specific and may not be feasible or useful for
minimizing impacts in all scenarios. A few commenters stated that the
Corps should not adopt additional national BMPs or other restrictions,
and said that such practices should be addressed at the regional level
and tailored to local environments, which will allow for greater
flexibility. A few commenters said that adding additional BMPs or
standards to this NWP would result in redundant requirements to manage
on these projects without providing additional benefits.
The Corps agrees that BMPs should be implemented where appropriate
and practical, and that it would be more appropriate and efficient to
add BMPs to this NWP either through regional conditions added to the
NWP by division engineers or activity-specific conditions added to the
NWP by district engineers. During its review of the suggested BMPs, the
Corps determined that many of these BMPs that are appropriate to apply
nationwide would not be appropriate for the NWP at a national level,
but they may be appropriate on a region level. The proposed text of NWP
includes some BMPs (e.g., requiring no changes in preconstruction
contours of waters of the United States, requiring the top 6 to 12
inches of the trench in wetlands to normally be backfilled with topsoil
from the trench, removal of temporary fills upon completion of the
work).
Many commenters said that the placement of temporary matting in
jurisdictional wetlands should continue to be a BMP for proposed NWP C
activities to minimize adverse environmental effects. Several
commenters recommend requiring the use of low-ground pressure
equipment, such as heavy equipment that has been specially designed to
spread the weight of the equipment over a larger area, which helps
avoid permanent impacts by reducing compaction of wetland soils. One
commenter said that use of wattles (i.e., erosion and sediment control
devices used to minimize erosion on construction sites) is a general
accepted practice to reduce water flow velocities and prevent sediment
from flowing into jurisdictional waters. The Corps believes these BMPs
are more appropriately applied on a case-by-case or regional basis, in
consideration of the characteristics of the affected ecosystems,
instead of a national basis.
One commenter stated that the Corps should continue to clearly
outline performance criteria within jurisdictional areas because it
provides the flexibility needed to facilitate the improvement and
development of construction practices that could better protect aquatic
resources. One commenter recommended adding a requirement that
directional drilling under waters of the United States should be a
national standard. One commenter suggested the addition of a BMP to
require district engineers to distribute relevant PCNs to state
agencies involved in the regulatory oversight or environmental review
of projects authorized by the new NWP C. With this NWP, the Corps
outlines certain performance criteria (e.g., removal of temporary
fills, uses of temporary mats) within jurisdictional waters. The Corps
believes the recommended BMPs are applied more appropriately and
effectively on a case-by-case or regional basis instead of a national
basis.
One commenter suggested a BMP where the project proponent tries to
cut only vegetation that exceeds a height of 12 feet and allows all
low-growing trees and shrubs to remain in place. This commenter said
that a benefit of this BMP is that it allows roots to remain in place
providing soil stabilization in and around jurisdictional waters. One
commenter noted that non[hyphen]mechanized clearing is preferred
consistent with the Corps' regulations at 33 CFR 323.2(d) along with
hand clearing, low ground pressure equipment and mats, to minimize and
avoid additional impacts to the jurisdictional water or wetland beyond
conversion are significantly minimized or avoided. The Corps believes
the recommended BMPs are applied more appropriately and effectively on
a case-by-case or regional basis instead of a national basis.
One commenter said that vibratory plowing is preferred over
trenching methods for burying both distribution and fiber optic lines
because vibratory plowing under most conditions does not create
incidental addition of material. One commenter recommended requiring
that material resulting from trench excavation may be temporarily side
cast into waters of the United States for very short periods of time
well within the limitation of three months, and is not placed in such a
manner that it is dispersed by currents or other forces. In addition,
this commenter suggested requiring side[hyphen]cast material to be
protected so it does not discharge offsite or into jurisdictional
waters during rainfall events. The Corps believes the recommended BMPs
are applied more appropriately and effectively on a case-by-case or
regional basis instead of a national basis.
One commenter remarked that while burying utilities is an important
climate adaptation strategy to address wildfire impacts, such
activities should be undertaken in an ecologically responsible fashion,
and recommended prohibiting NWP C activities within or under coastal
zone waters and wetlands. The Corps does not agree that NWP C
activities should be prohibited in coastal zone waters and wetlands.
A few commenters provided the following list of various practices
its members implement to help ensure that electric utility line
construction and maintenance activities will have no more than minimal
adverse environmental impacts:
Avoiding surface waters when embedding structures
(footings, poles, etc.), stockpiling materials, and setting up work
areas. Locating poles and tower foundations outside of surface waters
to the extent practicable. Where practicable, poles or structures are
sited in uplands so that the infrastructure ``spans'' and thereby
avoids the aquatic environment.
When it is not possible to span an aquatic environment,
poles or structures are installed in a manner to maintain conductor
clearance consistent with North American Electric Reliability
Corporation (``NERC'') and other guidelines to ensure safe and reliable
operation.
Installing mats before placing or driving equipment over
wetlands or streams.
Constructing roads with pervious materials and limiting
width and elevation, so long as access is safe.
Relying on low water crossings and appropriately sized
culverts.
Designing site plans to address the prevention,
containment, and cleanup of sediment or other materials caused by the
inadvertent returns of drilling fluids when installing electric utility
lines under streams or other waters via directional drilling.
Locating stockpile and work areas outside of surface
waters.
Performing frequent inspections of environmental and
safety measures and construction activities.
Marking waters of the United States near work areas with
flagging or perimeter fencing
Deploying mats prior to driving over or placing heavy
equipment on wetlands.
Installing stormwater BMPs to prevent erosion of hillsides
adjacent to construction areas.
Where practicable, trench material is side casted onto
uplands or onto filter cloth, mats, or some other semi-permeable
surface in vegetated wetlands.
[[Page 2817]]
Site plans are designed to address the prevention,
containment, and cleanup of sediment or other materials caused by the
inadvertent returns of drilling fluids when installing electric utility
lines under streams or other waters via directional drilling. In the
event of an inadvertent return of drilling fluids, the agency is
notified, and the remediation plan is implemented.
Where permanent access is not required, avoidance measures
are deployed to minimize impacts to jurisdictional waters to the
maximum extent possible.
Where permanent roads are required, they are typically
limited in width and elevation to the minimum necessary for safe access
and constructed with pervious materials.
Stockpiles and work areas are generally established
outside of surface waters.
Timber mats are typically installed prior to placing or
driving equipment over wetlands or streams.
Frequent inspections of environmental and safety measures
and construction activities are performed. Monitoring during and after
construction to avoid unauthorized discharges to surface waters.
Construction personnel, contractors, and personnel who
operate and maintain the electric utility and telecommunication lines
are trained to understand and comply with permit requirements and
conditions.
Several commenters suggested the following BMPs for proposed NWP C
based on Avian Powerline Interaction Committee documents. Their
recommended BMPs include:
Avian Protection Plan (APP) Guidelines.
Suggested Practices for Avian Protection on Power Lines.
Reducing Avian Collisions with Power Lines: State of the
Art in 2012.
Region 6 Guidance for Minimizing Effects from Power Line
Projects Within the Whooping Crane Migration Corridor (available at
https://puc.sd.gov/commission/dockets/electric/2019/el19-003/memo.pdf.)
The Corps believes the recommended BMPs are applied more
appropriately and effectively on a case-by-case or regional basis
instead of a national basis. The Corps has been administering NWP 12
since it was first issued in 1977 without extensive BMPs at the
national level and has found that the current approach with the BMPs
that are already in the text of the utility line NWPs (i.e., NWPs 12,
57, and 58) is effective.
A few commenters stated that the proposed NWP C will allow for
increased impacts to rivers and wetlands. One commenter said that
mechanized land clearing in forested and scrub-shrub wetlands for
utility line installation should not be authorized under NWP C and that
individual permits should be required for those activities. One
commenter said that individual permits should be used to authorize the
entire electric utility line project when one crossing does not meet
the limits for NWP C. One commenters states that it is not clear how
temporal and cumulative impacts will be considered when evaluating
facilities proposed to be authorized by NWP C or by multiple NWPs. A
few commenters recommend that the Corps adopt a policy of early
consultation with Indian tribes and other actors on these types of
projects, above the timeline required by the NHPA section 106 process.
One commenter recommended that the Corps require prior consent on
projects impacting tribes.
The proposed NWP C will not result in increased impacts to rivers
and wetlands because it has the same limits as the NWP 12 that was
issued in 2017 and in several prior reissuances of the NWPs. The
activities authorized by this NWP must comply with 33 CFR 330.6(d),
which addresses the use of NWPs with individual permits. During the PCN
review process, district engineers evaluate the individual and
cumulative effects of the activities authorized by an NWP (see
paragraph 2 of Section D, District Engineer's Decision). For Corps
districts consult with tribes when necessary for activities authorized
by this NWP and other NWPs. Issuance of an NWP verification by a
district engineer does not require prior consent from tribes.
Several commenters expressed concern about the impacts that
electric utility lines may have on migratory avian populations from
collisions with power lines. These commenters said that the Corps needs
to analyze the potential harm to bird populations from its permitting
of utility lines pursuant to this proposed NWP. These commenters said
that national programmatic ESA section 7 consultation should be
initiated for the issuance of this NWP, to allow the Services to work
with the Corps to establish national BMPs. Another commenter stated
that the Corps should consider voluntarily performing ESA Section 7
consultation on the issuance of this NWP to provide regulatory
certainty.
The national decision document has been revised to discuss
potential impacts of electric utility lines on migratory birds. General
condition 19 addresses compliance with the Migratory Bird Treaty Act
and the Bald and Golden Eagle Protection Act. That general condition
states that the permittee is responsible for ensuring that the activity
authorized by an NWP complies with both of these acts, and that the
permittee is responsible for contacting the appropriate office of the
U.S. FWS to determine whether any incidental take permits are necessary
and available under the Migratory Bird Treaty Act or Bald and Golden
Eagle Protection Act. Compliance with the ESA for this rulemaking is
discussed in Section III.D of this final rule.
One commenter emphasized that safety must remain paramount when
constructing, maintaining, repairing, and replacing above-ground and
below-ground electrical utility lines. The commenter suggested that the
Corps reference safety standards as a means of ensuring that electric
utility activities are conducted safely. One commenter said that the
proposal also describes the two methods by which underground electric
transmission cables are installed: Trenching and backfilling or
horizontal directional drilling. This commenter remarked that members
may also utilize conventional boring to install electric utility lines,
and asked that the Corps acknowledge that conventional boring is
another method used for installation of underground electric
transmission cables.
The Corps does not have the authority to require and enforce safety
standards that apply to the construction, maintenance, repair, and
replacement of above-ground and below-ground electrical utility lines.
Safety standards and requirements may be imposed by other federal
agencies, or state and local government agencies. This NWP authorizes
activities that may involve directional boring, as long as those
activities involve discharges of dredged or fill material into waters
of the United States or cross navigable waters of the United States.
Proposed new NWP C is issued as NWP 57, with the modifications
discussed above.
(16) NWP 58. Utility Line Activities for Water and Other Substances
The Corps proposed this new NWP as NWP D, to discharges of dredged
or fill material into waters of the United States, and structures and
work in navigable waters of the United States, for utility line
activities for water and other substances, such as potable water,
sewage, stormwater, and wastewater.
Several commenters stated that they support the issuance of new NWP
D for water, wastewater, and stormwater utility lines because of the
national legal
[[Page 2818]]
uncertainty of oil and gas pipeline projects. Many commenters said they
support the issuance of NWP D because it streamlines the permitting
process, clarifies the PCN requirements, separates activities based on
the utility types, and ensures the activities will cause no more than
minimal adverse environmental effects. Several commenters stated they
were opposed to the issuance of NWP D and recommend withdrawing NWP D
because it authorizes activities that cause significant adverse
impacts, and these activities should require individual permits. These
commenters stated, that at a minimum, additional PCN requirements
should be added to the proposed NWP.
The activities authorized by NWP D will generally result in no more
than minimal individual and cumulative adverse environmental impacts,
and certain activities require pre-construction notification to the
district engineer. District engineers will review PCNs for proposed NWP
D activities, and may add permit conditions, including mitigation
requirements, to the NWP authorization to help ensure that the
authorized activities cause no more than minimal adverse environmental
effects. District engineers can also exercise discretionary authority
and suspend or revoke the NWP authorization for proposed activities
that will result in more than minimal adverse environmental effects.
The Corps believes that the two PCN thresholds in proposed NWP D will
provide district engineers with the opportunity to review utility line
activities for water and other substances that have the potential to
cause more than minimal adverse environmental effects.
Several commenters expressed opposition to allowing multiple
segments as ``single and complete projects'' of the same pipeline
qualify for NWP authorization because it violates the Clean Water Act's
minimal impact limitation, the National Environmental Policy Act, the
Endangered Species Act, and other legal requirements for rigorous and
transparent environmental reviews and safeguards. In addition, several
of these commenters stated the authorizing multiple segments as single
and complete projects does not capture cumulative effects.
The use of NWPs to authorize separate and distant crossings of
waters of the United States for utility lines and roads as single and
complete has been in the Corps' NWP regulations at 33 CFR 330.2(i)
since 1991. The National Environmental Policy Act is a procedural
statute that does not prohibit any specific regulatory approaches or
mandate specific outcomes. Activities authorized by NWP D must comply
with general condition 18, endangered species. The requirements of
paragraph (b)(4) of general 32 help ensure that district engineers have
information regarding the crossings of waters of the United States that
require PCNs or do not require PCNs, so that the cumulative adverse
environmental effects can be assessed during the review process.
Several commenters stated opposition to the removal of the five PCN
requirements from the 2017 NWP 12 because they believe the Corps will
no longer receive notice of activities that cause more than minimal
adverse effects, nor will other federal and state natural resource
agencies be able to review and provide comments. Many commenters
opposed the removal of the non-PCN requirements for right-of-way
mechanized land clearing through forested wetlands because this
activity causes fragmentation and a loss/conversion of wetland type and
associated functions. The commenters requested addition of a
requirement for the submittal of a PCN for land clearing associated
with utility line rights-of-way within wetlands so that the Corps and
interested stakeholders can ensure impacts are appropriately avoided
and mitigated. A few commenters stated that the 500 linear foot PCN
threshold from the 2017 NWP 12 should be added to NWP D. One commenter
said that the PCN requirement for temporary access roads should be
retained. One commenter stated that a PCN should be required when the
proposed activities would run parallel with a stream bed.
The removal of the five PCN thresholds from NWP 12 are discussed in
the preamble discussion of NWP 12 and the same reasoning applies to the
removal of these PCNs from NWP 58. That preamble discussion includes
responses to comments, and that discussion will not be repeated in this
section of the preamble. The Corps declines to add the suggested PCN
thresholds because this NWP requires restoration of temporary fills to
pre-construction elevations. If utility line activities associated with
the suggested PCN thresholds result in a permanent impact that causes
the loss of greater than \1/10\-acre of waters of the United States,
then PCNs are required.
A few commenters said there needs to be an overall acreage limit on
authorized impacts for this NWP, including a maximum acreage for non-
PCN forest clearing activities, and a maximum length of impervious
surface roads before a PCN is required. One commenter stated that the
Corps needs to provide sound, scientific evidence that the removal or
omission of any of the PCN thresholds from the 2017 NWP 12 would not
harm river, stream, or wetland hydrologic functions.
The activities authorized by this NWP are subject to a \1/2\-acre
limit for each single and complete project. There was no PCN
requirement for temporary access roads in the 2017 NWP 12 and the Corps
continues to believe that it is not necessary to ensure no more than a
minimal individual or cumulative adverse environmental effects. Pre-
construction notification thresholds are established for proposed
activities requiring DA authorization that have the potential to cause
more than minimal adverse environmental effects. Pre-construction
notifications are informed by science and the Corps experience in
administering the NWP program. In this instance, the Corps has
determined it can remove the respective PCN requirements without
risking more than a minimal individual or cumulative adverse
environmental effects.
Some commenters said that the reduction of the PCN thresholds will
simplify NWP D and would not cause a negative impact on the
environment. One commenter asserted that permanent access roads should
be authorized under NWP 14, not NWP D. One commenter recommended adding
a requirement for horizontal directional drilling under waters of the
United States, as a national standard under NWP D. One commenter
recommended adding a provision to NWP D requiring containment and clean
up contingency plans.
The Corps declines to add a requirement for the use of horizontal
directional drilling because that technique is not always practical or
feasible for utility lines that convey water and other substances. The
use of horizontal directional drilling is more appropriately determined
on a case-by-case basis after considering the characteristics of the
proposed utility line activity, including site characteristics. The
Corps does not have the authority to require containment and cleanup
contingency plans for the construction, expansion, maintenance, or
repair of utility line activities for water and other substances.
One commenter stated that the Corps should define a ``stand-alone
project'' as a utility line project that includes all crossing within a
major watershed as evaluated together as single and complete, since the
cumulative impacts are to one system. The commenter said that an
alternative approach would be to require a cumulative analysis for all
proposed NWP D activities. Several
[[Page 2819]]
commenters requested clarification of the status of ongoing, non-oil
and gas utility projects verified under the 2017 NWP 12, specifically
whether they will continue to be authorized under the 2017 NWP 12 until
the March 18, 2022 expiration date, or if they will need to be
reverified.
The Corps declines to add a definition of ``stand-alone project''
to this NWP. When reviewing PCNs for proposed NWP activities, district
engineers evaluate the crossings of waters of the United States that
require PCNs and the information provided on other crossings in
accordance with paragraph (b)(4) of general condition 32. They will
determine whether the proposed utility line for water and other
substances will result in no more than minimal individual and
cumulative adverse environmental effects. The grandfathering provisions
for these NWPs, including the transition from 2017 NWP 12 to the 2021
NWP 12 and new NWPs 57 and 58, is discussed in Section I.D. of this
final rule.
A few commenters requested that the Corps broaden the definition of
the term ``utility line'' so that it includes other types of man-made
conveyances, such as canals and other linear conveyances that are
subject to Clean Water Act section 404 jurisdiction and can transport
water. One commenter requested the addition of specific waterline
ancillary facilities including, but not limited to pump plants,
siphons, and tunnels to the text of this NWP. One commenter said that
the Corps should clarify whether this NWP authorizes utility line
activities that convey substances that are unclear as to whether they
included in the definition of ``oil or natural gas pipeline'' in NWP
12, such as hydrogen and power-to-gas (i.e., hydrogen combined with
carbon dioxide to create methane, or renewable natural gas). One
commenter recommended further defining the term ``other substances'' in
this NWP.
The Corps declines to add canals and ditches to the activities
authorized by this NWP. Canals and ditches can be authorized by other
NWPs, if the construction of those ditches involves discharges of
dredged or fill material into waters of the United States or structures
or work under Section 10 of the Rivers and Harbors Act of 1899.
Substations for utility lines for water and other substances can
include pump plants and siphons. Tunnels may be authorized if they a
considered utility lines. Utility lines constructed to convey hydrogen
or carbon dioxide can authorized by NWP D, but utility line activities
constructed to convey renewable natural gas should be authorized by NWP
12. In general, ``other substances'' includes substances not conveyed
by utility lines authorized by NWPs 12 and 57. The Corps has added
``products derived from oil or natural gas'' to be consistent with the
definition of ``oil or natural gas pipeline'' in NWP 12, and to clarify
that regulated activities associated with pipelines that carry
substances derived from oil or natural gas should be authorized by NWP
12, not NWP D.
One commenter said that Note 4 should refer to the General Bridge
Act of 1946 instead of Section 9 of the Rivers and Harbors Act of 1899.
The Corps has made this change to Note 4.
One commenter requested clarification on how temporal and
cumulative impacts will be considered when evaluating activities
authorized by NWP D. This commenter recommended conducting a separate
analysis for temporal and cumulative impacts on streams, wetlands, and
other waters. A few commenters recommended changing the provision
condition that states ``there must be no change in pre-construction
contours of waters of the United States'' to ``there must be no change
in pre-construction contours which results in permanent losses of
waters of the United States.'' One commenter requested clarification on
the measures the Corps will take to ensure that the activities
authorized by NWP D are not improperly divided into smaller sections to
avoid an individual permit.
Temporal and cumulative impacts will be evaluated using the 10
criteria identified in paragraph 2 of Section D, District Engineer's
Decision. The Corps declines to change the text regarding the
requirement for no changes in pre-construction contours, because that
has been a BMP that has helped ensure that most utility line activities
result in temporary impacts. The Corps applies the definitions of
``single and complete linear project'' to NWP D activities and to other
NWPs that authorize utility lines to determine which activities can be
authorized by an NWP and which activities require individual permits.
The Corps also implements 33 CFR 330.6(d), which addresses the use of
individual permits with NWPs.
Several commenters stated that BMPs should be site-specific and
imposed as special conditions, if necessary, and not standardized in
the text of NWP D. One commenter said that the inclusion of standards
and BMPs would likely impede the objective of the NWP program by
causing delays and increasing paperwork. This commenter asserted that
attempting to establish national standards could cause conflicting
requirements between the NWP and Clean Water Act Section 401.
The Corps agrees that most BMPs are site-specific and should be
identified for specific utility line activities. Best management
practices may also vary by region and by aquatic resource type. Best
management practices that are necessary to ensure that activities
authorized by NWP D have no more than minimal adverse environmental
effects are more appropriately identified by district engineers and
required through activity-specific conditions added to the NWP
authorization or through the section 401 water quality certification
process.
One commenter said that the Corps should adopt a policy of early
consultation with the tribes and other interested parties for these
types of projects over and above the NHPA section 106 process to avoid
litigation, and other costly delays. This commenter also requested the
Corps require consent on projects impacting tribes. One commenter
recommended evaluating the direct, indirect, and cumulative effects on
treaty reserved resources, including anadromous salmonids and their
habitat to fully understand the potential extent of resource impacts.
The Corps consults with tribes when necessary to ensure that
activities authorized by an NWP comply with general condition 17,
tribal rights. As part of this rulemaking, Corps districts have
consulted and coordinated with tribes to identify regional conditions
and coordination processes to ensure protect tribal rights, as well as
tribal trust resources. Activities authorized by NWPs do not require
prior consent from tribes.
One commenter said that the Corps should end the practice of
counting temporary impacts associated with matting for moving heavy
machinery over a wetland, as a loss of greater than \1/10\-acre, which
triggers a requirement to submit a PCN. One commenter stated the Corps
districts should maintain consistency with the PCN thresholds and
should not be allowed to add regional conditions to this NWP that
undercuts the reduction in PCN thresholds in this NWP. This commenter
said that regional conditions cause confusion and inefficiencies,
especially if the linear infrastructure crosses into multiple Corps
districts.
The determination regarding whether the use of matting during
utility line activities authorized by NWP D causes a loss of waters of
the United States that may require a PCN is more appropriately made by
district engineers on a case-by-case basis. Division engineers can add
regional conditions to
[[Page 2820]]
this NWP that replace PCN thresholds that were removed, if they
determine those PCN thresholds are necessary to ensure that this NWP
authorizes only those activities that have no more than minimal adverse
environmental effects. Regional conditions are intended to address
regional differences in aquatic resource functions, so there may be
some inconsistency that must be dealt with, especially for utility
lines that run through multiple states or Corps districts.
One commenter said that water mains are known to exceed the non-oil
and gas pipeline diameters, identified in the preamble as 3 to 24
inches, as they may be 6 feet or wider. This commenter stated the Corps
did not provide a robust analysis of the lengths of the various utility
line, nor did they provide the total national mileage for these lines,
as they could be quite long and have similar types of impacts as oil or
gas pipelines. A few commenters recommended removing natural gas
pipelines (i.e. residential lines), hydrogen transport lines for clean
energy solutions, and local, intrastate utility lines operated as an
independent municipally-owned distribution system from NWP 12, because
they are typically similar or smaller in size with respect to
materials, location, installation footprint, and constructed along with
water and wastewater pipelines.
The intent of the preamble discussion in the 2020 Proposal
regarding the proposal to issue separate NWPs for oil or natural gas
pipelines, electric utility lines and telecommunications lines, and
utility lines for water and other substances was to illustrate some of
the differences among those utility line sectors. The discussion of
pipeline diameters has no relevance to the text of these NWPs, or to
the conditions that apply to those NWPs. Utility line activities
authorized by NWP D can be used to convey hydrogen, and for local
distribution of water, sewage, wastewater, and other substances.
One commenter expressed concerns regarding the proposed issuance of
NWP D to authorize utility line activities that carry wastewater. This
commenter stated that distribution systems for wastewater reuse
applications should be assumed to carry highly toxic and potentially
hazardous substances that would degrade soils and groundwater if leaked
or spilled. One commenter said that allowing activities under NWP D
within or under coastal zone waters and wetlands will impermissibly
degrade water quality, which is inconsistent with Section 404(e) of the
Clean Water Act. One commenter stated that the NWP should be modified
to require access roads to be built in accordance with local or state
standards.
Prior versions of NWP 12 have authorized utility line activities
that carry wastewater, so this is not a new issue for the NWP program.
General condition 14 requires proper maintenance of activities
authorized by NWPs, so utility lines carrying wastewater should
minimize the potential for leaks and spills. The Corps does not have
the authority to regulate leaks or spills from utility lines. Leaks and
spills are more appropriately addressed through federal, state, and
local laws that are administered by other federal agencies, or state or
local government agencies. This NWP can be used to authorize utility
line activities for water and other substances in coastal zones. Local
and state governments are responsible for ensuring that access roads
are constructed in accordance with their standards.
Proposed NWP D is issued as NWP 58 with the modification discussed
above.
H. Responses to Comments on the Nationwide Permit General Conditions
GC 1. Navigation. The Corps did not propose any changes to this
general condition. The Corps did not receive any comments on this
general condition. The general condition is adopted as proposed.
GC 2. Aquatic Life Movements. The Corps did not propose any changes
to this general condition. One commenter noted that some project
proponents bury the bottom portion of larger culverts to allow fish
passage and create a natural bottom for habitat. One commenter
expressed support for the Corps' retention of the existing definition
given the wide variability of geomorphic and hydrologic settings in
which NWP activities are conducted. One commenter stated that the
Corps' preference for bottomless culverts, one-barrel culverts, or
bridges should be explained. Another commenter said that in the absence
of special concerns, such as endangered species, there should not be a
preference for bottomless culverts. One commenter remarked that the
text of this general condition is insufficient without specific
monitoring and enforcement protocols to ensure that effects of NWP
activities on aquatic life movements are no more than minimal.
The Corps acknowledges that burying the bottom portion of a larger
culvert and creating a natural bottom for habitat is an acceptable
approach for complying with this general condition. The Corps
appreciates the commenter's support for providing flexibility in this
general condition for addressing variations in the geomorphic and
hydrologic settings in which NWP activities are conducted. The
preference for bottomless culverts is based on the ability of
bottomless culverts to facilitate the continuity of aquatic life
movements, including during low-flow conditions. The general condition
does not mandate the use of bottomless culverts. Bottomless culverts
can be beneficial to a wide variety of aquatic species, not just
endangered or threatened species. Bottomless culverts can provide
connectivity for a wide variety of species, including aquatic species
that provide important ecosystem functions and services, and aquatic
species that have economic and recreational value. District engineers
retain the authority to conduct compliance inspections to ensure that
permittees comply with this general condition. In most circumstances,
compliance monitoring is sufficient to determine compliance with this
general condition, instead of requiring monitoring and data collection
over a period of time.
The general condition is adopted as proposed.
GC 3. Spawning Areas. The Corps did not propose any changes to this
general condition. One commenter expressed support for the Corps'
reissuance of this general condition without changes. The Corps
appreciates the support for the reissuance of this general condition.
The general condition is adopted as proposed.
GC 4. Migratory Bird Breeding Areas. The Corps did not propose any
changes to this general condition. The Corps did not receive any
comments on this general condition. The general condition is adopted as
proposed.
GC 5. Shellfish Beds. The Corps did not propose any changes to this
general condition. The Corps did not receive any comments on this
general condition. The general condition is adopted as proposed.
GC 6. Suitable Material. The Corps did not propose any changes to
this general condition. One commenter stated that the condition should
be refined to align with state water quality standards, specifically
relative to nutrients and nutrient loading. Concerns about compliance
with applicable state water quality standards or requirements are more
appropriately addressed through the water quality certification
requirements for proposed discharges of dredged or fill material into
waters of the United States. The general condition is adopted as
proposed.
GC 7. Water Supply Intakes. The Corps did not propose any changes
to this general condition. One commenter expressed support with
reissuance of
[[Page 2821]]
the GC without change. The Corps acknowledges this commenters support
for the reissuance of this general condition. The general condition is
adopted as proposed.
GC 8. Adverse Effects from Impoundments. The Corps did not propose
any changes to this general condition. The Corps did not receive any
comments on this general condition. The general condition is adopted as
proposed.
GC 9. Management of Water Flows. The Corps did not propose any
changes to this general condition. The Corps did not receive any
comments on this general condition. The general condition is adopted as
proposed.
GC 10. Fills Within 100-Year Floodplains. The Corps did not propose
any changes to this general condition.
A few commenters stated that the Corps should prohibit the use of
NWPs and many other activities in 100-year floodplains and high-risk
hurricane evacuation zones because of increasing risks of climate
change and sea level rise. One commenter stated that the Corps'
requirement in the condition to comply with FEMA-approved state or
local floodplain management requirements is insufficient to ensure that
authorized activities have no more than minimal adverse environmental
effects and comply with the Clean Water Act, the Endangered Species
Act, and the National Environmental Policy Act. One commenter said that
``high impact'' NWPs should be prohibited from use in floodplains and
that individual permits should be required for those activities. this
commenter also stated that this general condition should be revised to
prohibit the use of certain NWPs to authorize discharges of dredged or
fill material into waters of the United States that result in permanent
above-grade fills in mapped 100-year floodplains or floodways, in order
to comply with Executive Order 11988, Floodplain Management.
The Corps does not have the authority to regulate activities in
100-year floodplains or high-risk hurricane evacuation zones, except
for discharges of dredged or fill material into waters of the United
States that may be located within those floodplains or evacuation
zones. The primary responsibility for determining zoning and land use
matters, including development activities in 100-year floodplains and
high-risk hurricane evacuation zones, lies with state, local and tribal
governments (see 33 CFR 320.4(j)(2)). This general condition is
consistent with the item 2 of Section E, Further Information, which
states that the NWPs do not obviate the need to obtain other federal,
state, or local permits, approvals, or authorizations required by law.
State and local governments are the entities that have primary
responsibility for regulating land uses within floodplains and other
areas.
Under the discretionary authority provision at 33 CFR 330.1(d) and
other provisions of the NWP regulations at 33 CFR part 330, division
and district engineers can further condition or restrict the
applicability of an NWP for cases where they have concerns for the
aquatic environment under the Clean Water Act section 404(b)(1)
Guidelines or for any factor of the public interest. There are two
public interest review factors related to floodplains in the Corps'
public interest review regulations at 33 CFR 320.4(a)(1) that could be
used as a basis for exercising discretionary authority: Floodplain
values and flood hazards.
Nationwide permit activities, including discharges of dredged or
fill material into waters of the United States within floodplains,
comply with the Endangered Species Act through the requirements of NWP
general condition 18. The National Environmental Policy Act is a
procedural statute, and does not mandate any substantive floodplain
management requirements. The Corps complies with NEPA requirements when
it prepares the national decision documents for the issuance,
reissuance, or modification of NWPs, and discusses potential impacts to
flood hazards and floodplain values in its public interest review
evaluation. The proposed NWPs, including general condition 10, are
consistent with E.O. 11988, Floodplain Management, with respect to the
Corps' authority to regulate specific activities that may occur in
floodplains (i.e., discharges of dredged or fill material into waters
of the United State). In each national decision document for the final
NWPs, the Corps considered potential impacts to floodplain values and
flood hazards.
The general condition is adopted as proposed.
GC 11. Equipment. The Corps did not propose any changes to this
general condition. One commenter expressed support for reissuance of
the general condition with no change. The Corps appreciates this
commenter's support for the reissuance of this general condition
without change.
The general condition is adopted as proposed.
GC 12. Soil Erosion and Sediment Controls. The Corps did not
propose any changes to this general condition. One commenter stated
that the condition should be modified to reference specific erosion
control standards or specifications that must be followed, particularly
for projects that exceed an acre of land disturbance. Specific soil
erosion and sediment control requirements vary among state and local
governments and other entities, and are more appropriately determined
on a case-by-case basis for specific NWP activities. Therefore, it
would be inappropriate to establish national standards for erosion
control.
The general condition is adopted as proposed.
GC 13. Removal of Temporary Structures and Fills. The Corps
proposed to modify this general condition to apply to temporary
structures. A few commenters expressed support for the addition of
temporary structures to this general condition. A few commenters
objected to the addition of temporary structures to this general
condition, stating that their removal may cause more harm than leaving
them in place because temporary structures are not all alike. One
commenter requested a definition of ``temporary.'' In contrast, another
commenter supported leaving the definition of ``temporary'' to the
district engineer's discretion. One commenter requested that the Corps
add preamble language to the final rule that states that the removal of
structures should occur after they have fulfilled their intended
purpose. This commenter further stated that the project proponent
should determine when the structure has fulfilled its intended purpose.
What constitutes a temporary structure should be determined on a
case-by-case basis. Therefore, the Corps declines to define
``temporary'' for the purposes of this general condition. The Corps has
changed the text of this general condition as it relates to temporary
structures. The general condition now states that temporary structures
must be removed, to the maximum extent practicable, after their use has
been discontinued. The Corps recognizes that it might not be feasible
to completely remove the structure after its use has been discontinued.
For example, it might not be feasible to remove an entire piling from
navigable waters after it is no longer needed, but the project
proponent could remove that portion of the piling that extends above
the bottom of the waterbody so that it no longer is an obstruction at
the water surface. The Corps also acknowledges that attempting to
remove a temporary structure in its entirety has the potential to cause
more substantial adverse environmental effects than leaving a portion
of the structure in place.
The general condition is adopted with the modifications discussed
above.

GC 14. Proper Maintenance. The Corps did not propose any changes to
this general condition. No comments were received. The general
condition is adopted as proposed.
GC 15. Single and Complete Project. The Corps did not propose any
changes to this general condition. One commenter expressed support for
reissuance of this general condition with no change. The general
condition is adopted as proposed.
GC 16. Wild and Scenic Rivers. The Corps did not propose any
changes to this general condition. No comments were received on this
general condition.
The general condition is adopted as proposed.
GC 17. Tribal Rights. The Corps proposed to modify this general
condition to restore the text that was in the general condition for the
2012 NWPs and prior NWPs to eliminate any confusion about the
applicable standards that apply when considering potential impacts to
tribal treaty rights when consulting with tribes, and when determining
the applicability of an NWP for a proposed activity. The proposed
changes to this general condition are also intended to clarify that the
identification of a potential effect to a tribal right does not mean
that a district engineer must exercise his or her discretionary
authority to require an individual permit for a proposed activity. The
proposed changes to this general condition were also intended to avoid
any confusion between tribal consultation policies, tribal rights, and
the requirements of the Corps' permitting authorities.
Many commenters objected to the proposed changes to general
condition 17 and many commenters expressed support for the proposed
change. Many commenters stated that the 2017 general condition's use of
the ``no more than minimal effects on'' standard is clearer than the
``impair'' standard the Corps proposes to revert to because the ``no
more than minimal adverse effects'' standard used throughout the NWPs.
One commenter stated that ``impair'' is a clearer standard. Many
commenters asserted that use of ``no more than minimal effect''
threshold in the general condition is consistent with Section 404(e) of
the Clean Water Act and would not be confusing to retain in the general
condition. Several commenters remarked that a minimal effect
determination is well established in guidance and regulation and use of
the word ``impair'' provides no additional clarity.
The Corps is returning the text of this general condition to the
text that was in the 2012 NWPs and prior NWPs to eliminate any
confusion about the applicable standards that apply when considering
potential impacts to tribal treaty rights when consulting with tribes,
and when determining the applicability of an NWP for a proposed
activity. By using the word ``impair'' instead of ``no more than
minimal adverse effects on'' the general condition will be clearer that
the NWPs do not change existing tribal trust duties of the Corps, or
the rights of tribes. Rather, the proposed changes to the general
condition will serve as a guide to users when undertaking tribal
consultations regarding the application of an NWP to a particular
activity, and when developing protocols regarding tribal notification
that build upon the existing Department of Defense, Army, and Corps
tribal consultation policies. The Clean Water Act section 404(e)
requirement that no activity authorized by an NWP may cause more than
minimal adverse effects remains applicable in the context of potential
effects to tribal rights, resources, or lands.
Many commenters said that the change in language would result in
less protection for tribal rights and resources and is inconsistent
with the Corps' trust obligations. Many commenters stated that the
Corps provides no rationale for the proposed change considering its
rationale for changing the language in 2017. A few commenters stated
that tribes should receive copies of PCNs for all activities that occur
on tribal lands or off-reservation areas where treaty rights are
exercised. One commenter stated that the tribes should be allowed to
make the ``no more than minimal effect'' determination.
The change in the text of this general condition will not result in
less protection for tribal rights and resources. The rationale for the
proposed change was provided in the preamble to the 2020 Proposal (see
85 FR 57350). The 1998 Department of Defense American Indian and Alaska
Native Policy continues to apply to the NWPs and other DA permits. The
district engineer is authorized to determine whether a proposed NWP
activity will result in no more than minimal individual and cumulative
adverse environmental effects.
Many commenters said they are opposed to removing ``tribal lands''
and its definition from the suite of protected resources. Many
commenters expressed opposition to removing ``protected tribal
resources'' and its definition from the suite of protected resources.
Many commenters stated that the proposed wording would only protect
tribal treaty rights and not all tribal rights. A few commenters
suggested that the definition of tribal rights be moved to the text of
general condition 17. One commenter said that the change in general
condition 17 would not affect the Corps' tribal trust responsibilities.
One commenter recommended that the Corps delete unnecessary definitions
and should only retain definitions for ``tribal rights'' and ``tribal
lands'' as they pertain to general condition 17.
Protection of tribal lands will continue through the implementation
of the 1998 Department of Defense American Indian and Alaska Native
Policy. ``Protected tribal resources'' is an ambiguous term and removal
of that term from the general condition will result in a clearer, more
enforceable general condition with less risk of disputes and litigation
concerning whether particular resources are protected tribal resources.
The Corps is retaining the definition of ``tribal rights'' in the
``Definitions'' section of these NWPs (Section F). The Corps is also
retaining the definition of ``tribal lands'' in Section F of the NWPs.
Many commenters said that ``identification of a potential effect to
a tribal right does not mean that a district engineer must exercise his
or her discretionary authority to require an individual permit for a
proposed activity,'' is contrary to statutory authority and the Corps'
trust obligations. One commenter encouraged the Corps to engage
prospective applicants for projects that have a greater potential to
affect tribal rights in an optional pre-application meeting with the
tribes prior to submittal of an NWP verification request. One commenter
said that the general condition should include a statement requiring
the Corps to conduct meaningful consultation with potentially impacted
tribes in accordance with tribal protocols.
District engineers have the final decision-making authority as to
whether a proposed NWP activity that requires DA authorization
qualifies for NWP authorization. District engineers can coordinate with
tribes to help make these decisions, including whether a proposed NWP
activity complies with general condition 17. If a district engineer
holds a pre-application meeting with a project proponent, he or she has
the discretion to invite tribal representatives to attend the meeting.
When conducting government-to-government consultation with tribes,
district engineers endeavor to conduct meaningful consultation with
tribes.
One commenter suggested revising general condition 17 to read as
follows: ``No NWP activity may cause more than
[[Page 2823]]
minimal adverse effects to tribal rights, including treaty rights,
protected tribal resources such as ceded territory, any sacred/cultural
site/landscape or tribal lands, as determined by any concerned
tribe(s).'' Another commenter recommended revising this general
condition to read as follows: ``No activity or its operation may cause
adverse effects on tribal rights (including, but not limited to,
reserved water rights and treaty rights), protected tribal resources,
or tribal lands.'' As discussed above, the Corps is adopting the
proposed text of general condition 17.
Several commenters said that the change in language does not
support the Corps' rationale for the NWPs in light E.O. 13783,
``Promoting Energy Independence and Economic Growth.'' A few commenters
stated that the change in language would violate E.O. 13175. One
commenter suggested that the condition should include a statement
requiring the project proponent to obtain consent from potentially
impacted tribes for the NWP activity. One commenter requested a
definition of ``impair.'' One commenter suggested that the Corps
provide an approved list of tribal entities. One commenter suggested
that the Corps provide guidance and processes relative to consultation
and timelines.
General condition 17 was not discussed in the report issued by the
Office of the Assistant Secretary of the Army (Civil Works) in response
to E.O. 13783. This change in the text of general condition 17 does not
violate E.O. 13175. The Corps continues to consult with tribes on
proposed NWP activities when such consultation is warranted. The
district engineer determines whether a proposed activity requiring DA
authorization qualifies for NWP authorization, and consent from
potentially impacted tribes is not required for that determination. The
Corps does not believe it is necessary to develop an approved list of
tribal entities. Corps districts are aware of the tribes they may need
to consult with. The Bureau of Indian Affairs may be the appropriate
entity to develop and maintain such a list. The Corps Regulatory
Program follows a number of existing Department of Defense, Army, and
Corps tribal consultation policies. Information on these tribal
consultation policies are available at: https://www.usace.army.mil/Missions/Civil-Works/Tribal-Nations/.
This general condition is adopted as proposed.
GC 18. Endangered Species. The Corps proposed to modify this
general condition to make changes to be consistent with the U.S. Fish
and Wildlife Service's (FWS) and National Marine Fisheries Service's
(NMFS) Endangered Species Act (ESA) section 7 consultation regulations
that were published in the Federal Register on August 27, 2019 (84 FR
44976). Those regulations amended the definition of ``effects of the
action'' at 50 CFR 402.02 by removing the term ``indirect effects.''
Several commenters supported the proposed changes to ensure that
general condition 18 aligns with the current ESA implementing
regulations at 50 CFR part 402. A few commenters suggested that the
Corps incorporate the new ESA section 7 regulation definitions directly
into the general condition rather than by referencing provisions in the
Code of Federal Regulations. These commenters also suggested adding a
definition for ``action area'' to the text of the general condition.
The Corps believes that it is more appropriate to reference the
current ESA section 7 regulations in the general condition rather than
copying the text of the applicable provisions into the general
condition itself. During the process of determining whether a proposed
NWP activity ``may affect'' listed species or critical habitat, the
Corps will utilize the definition of ``action area'' at 50 CFR 402.02
and there is no need to provide the definition of that term in the text
of general condition 18.
Several commenters objected to the removal of ``direct effects''
and ``indirect effects'' definitions from the general condition and
asserted that ESA section 7 consultation compliance will not be
achieved without the analysis of the effects and/or would cause
significant adverse impacts to endangered species. One commenter
expressed opposition to the proposed change to general condition 18
because he or she is opposed to the 2019 amendments to the U.S. FWS's
and NMFS's ESA section 7 regulations. One commenter stated that the
Corps must seek concurrence from the U.S. FWS or NMFS for any ``no
effect'' determination.
The terms ``direct effect'' and ``indirect effect'' are no longer
used in 50 CFR part 402. When the district engineer evaluates a PCN for
a proposed NWP activity to determine whether the proposed activity
``may affect'' listed species or critical habitat, he or she applies
the definition of ``effects of the action'' at 50 CFR 402.02, as well
as the U.S. FWS's and NMFS's regulations for identifying activities
that are reasonably certain to occur (50 CFR 402.17(a)) and identifying
the consequences caused by the proposed action (50 CFR 402.17(b)). The
ESA section 7 consultation handbook issued by the U.S. FWS and NMFS in
1998 states that a federal agency is not required to obtain written
concurrence from the U.S. FWS or NMFS for its ``no effect''
determinations.
One commenter stated that clarification is needed as to what is
meant by non-Federal permittees that require pre-construction
notification under paragraph (c) of this general condition. A few
commenters said that the general condition only requires project
proponents to submit a PCN if a proposed activity might affect a
species or its critical habitat, which ignores the Corps responsibility
to conference on species proposed for listing. These commenters
suggested revising this general condition to include proposed species.
Several commenters requested clarification of the term ``in the
vicinity'' in paragraph (c) of this general condition. One commenter
said that the Corps inappropriately relies on information contained in
the PCN to make its effect determinations and must independently verify
the potential for a listed species to be affected.
Generally speaking, a non-federal permittee is a permittee that is
not a federal agency. There may be limited circumstances where a non-
federal agency might be considered as having ESA section 7 obligations
similar to those of a federal agency. For example, the Federal Highway
Administration may assign a state Department of Transportation the
responsibility for complying with non-NEPA environmental statutes such
as the ESA.
The Corps has modified paragraph (c) of this general condition to
be consistent with 33 CFR 330.4(f)(2), which states non-federal
permittees shall notify the district engineer if any Federally listed
(or proposed for listing) endangered or threatened species or critical
habitat might be affected or is in the vicinity of the project. The
Corps also added ``critical habitat proposed for such designation'' to
paragraph (c). These changes are necessary for species proposed for
listing and critical habitat proposed for such designation because
section 7(a)(4) of the ESA requires agencies to confer with the U.S.
FWS or NMFS on any agency action which is likely to jeopardize the
continued existence of any species proposed to be listed under section
4 of the ESA or result in the destruction or adverse modification of
critical habitat proposed to be designated for such species. The Corps
has modified the first sentence of paragraph (c) as follows: ``Non-
federal permittees must submit a pre-construction notification to the
district
[[Page 2824]]
engineer if any listed species or designated critical habitat (or
species proposed for listing or critical habitat proposed for such
designation) might be affected or is in the vicinity of the activity,
or if the activity is located in designated critical habitat or
critical habitat proposed for such designation, and shall not begin
work on the activity until notified by the district engineer that the
requirements of the ESA have been satisfied and that the activity is
authorized.'' The Corps has added ``species proposed for listing'' and
``critical habitat proposed for such designation'' where appropriate in
other sentences in this paragraph.
When reviewing a PCN for a proposed NWP activity that might affect
species proposed for listing or critical habitat proposed for such
designation, or is located in critical habitat proposed for such
designation, the district engineer will evaluate the effects of the
proposed NWP activity on the species proposed for listing or the
critical habitat proposed for designation. If the district engineer
determines that the proposed NWP activity is likely to jeopardize the
continued existence of any proposed species or result in the
destruction or adverse modification of proposed critical habitat, he or
she will initiate a conference with the U.S. FWS and/or NMFS in
accordance with 50 CFR 402.10. If the district engineer determines that
a conference is necessary, he or she will notify the non-federal
applicant within 45 days of receipt of a complete PCN. The activity is
not authorized by NWP until the district engineer has notified the
project proponent that the requirements of ESA section 7 have been
satisfied
The Corps added ``or conference'' to the second to last sentence of
paragraph (c) to address situations where the district engineer
conducts an ESA section 7 conference with the U.S. FWS or NMFS for a
proposed NWP activity that may affect a species proposed for listing or
proposed critical habitat. The Corps also modified paragraph (d) of
this general condition to state that as a result of a conference with
the U.S. FWS or NMFS the district engineer may add species-specific
permit conditions to the NWPs.
The Corps is adding ``or critical habitat proposed for such
designation'' to this general condition to ensure that these NWPs do
not authorize any activities that are likely to result in the
destruction or adverse modification of proposed critical habitat. The
general condition already prohibits the use of NWPs for any activity
that is likely to jeopardize the continued existence of species
proposed for listing. The prior exclusion of proposed critical habitat
was an administrative oversight.
The term ``in the vicinity'' for the purposes of paragraph (c) of
this general condition cannot be defined at a national level. What
constitutes ``in the vicinity'' can vary substantially by species,
environmental setting, the medium in which the species lives (e.g.,
water, air, or in the ground), and other factors. When reviewing a PCN,
the district engineer makes an independent determination of whether the
proposed activity ``may affect'' listed species or designated critical
habitat and thus requires ESA section 7 consultation. The district
engineer relies in part on information in the PCN, but he or she will
also utilize other information, including local knowledge of the area,
and the species and the habitats in which the listed species lives in.
One commenter said general condition 18 should require PCNs for
activities authorized by NWPs 3, 12, 13, 14, 21, 39, 44 and 48. One
commenter stated that the Corps must not rely solely on permittees
submitting PCNs to comply with its ESA obligations. One commenter
suggested revising the general condition to state that the ESA section
7 consultation for an NWP activity will cover the entire project, to
clarify that the entire action area must be examined and not just the
activities on lands under the Corps' jurisdiction.
All activities authorized by NWPs 21, 39, and 44 require PCNs to
district engineers. The district engineers will review those proposed
activities and determine whether ESA section 7 consultation is
required. Activities authorized by NWPs 3, 12, 13, 14, and 48 require
PCNs under specific circumstances, and district engineers will review
those PCNs to identify proposed activities that ``may affect'' listed
species or designated critical habitat. For those activities that do
not require PCNs under the text of those general permits, paragraph (c)
applies when the project proponent is a non-federal permittee. If any
listed species or designated critical habitat might be affected or is
in the vicinity of the proposed NWP activity, or if the proposed NWP
activity is located in designated critical habitat, then the project
proponent is required to submit a PCN so that the district engineer can
determine whether the proposed activity ``may affect'' listed species
or designated critical habitat. When determining the scope of the ESA
section 7 consultation, the district engineer applies the U.S. FWS's
and NMFS's regulations at 50 CFR part 402, including the definitions of
``action area'' and ``effects of the action.''
One commenter recommended that the Corps adhere to the 45-day
review time to determine whether a proposed NWP activity ``may affect''
or will have ``no effect'' on listed species. Alternatively, this
commenter suggested that the review period not exceed 90 days under any
circumstances. One commenter expressed support for the use of regional
programmatic ESA section 7 consultations to satisfy the requirements of
general condition 18.
Paragraph (c) of general condition 18 already requires the district
engineer to notify the non-federal applicant within 45 days of receipt
of a complete PCN whether the proposed activity will have ``no effect''
in listed species or designated critical habitat or where it ``may
affect'' listed species or designated critical habitat and require
section 7 consultation with the U.S. FWS and/or NMFS. If the district
engineer has to conduct section 7 consultation with the U.S. FWS or
NMFS, the consultation process may take longer than 90 days. Formal
section 7 consultations conclude within 90 days after initiation unless
the timeframe is extended in accordance with the section 7 regulations
at 50 CFR 402.14(e). For informal consultations, the U.S. FWS and NMFS
are required to provide written concurrence or non-concurrence with the
federal agency's ``may affect, not likely to adversely affect''
determination within 60 days, unless an extension occurs (see 50 CFR
402.13(c)(2)). The Corps cannot issue the NWP verification until the
section 7 consultation is completed and the applicant cannot proceed
without receiving a verification from the Corps as provided for in
paragraph (a)(2) of general condition 32 because compliance with ESA
cannot be waived. The Corps will continue to utilize regional
programmatic consultations for the NWPs, and work with the U.S. FWS and
NMFS to develop new regional programmatic consultations.
One commenter suggested changing paragraph (g) of general condition
18 to advise project proponents to only use the U.S. FWS's IPaC website
at (http://ww.fws.gov/ipac) because other websites are usually
outdated. This commenter also recommended requiring project proponents
to append the IPaC output document to their consultation package. One
commenter requested that the text of the general condition be modified
to include specific instructions on the process for ESA Section 7
consultation where the Corps has limited regulatory authority, such
linear projects where the Corps' jurisdiction is limited to crossings
of jurisdictional waters and
[[Page 2825]]
the crossings are separated by upland areas.
Project proponents should be allowed to use whatever information
that can help them determine whether the PCN threshold in paragraph (c)
of general condition 18 is triggered. The U.S. FWS's IPaC tool is just
one tool that might provide useful information to prospective
permittees. There may be other tools, such as databases and websites
managed by state and local governments and non-governmental
organizations that may be helpful in determining whether a proposed NWP
activity might affect listed species, if listed species are in the
vicinity of a proposed activity, or if the activity is located in
designated critical habitat. This includes listed species under the
jurisdiction of the NMFS, which are not included in IPaC. The Corps
does not believe that there should be a requirement to the output from
IPaC in the PCN because not all listed species are included in that
information system.
For linear projects, such as various types of utility line
activities authorized by NWPs 12, 57, and 58, the Corps applies the ESA
section 7 regulations at 50 CFR part 402, including the definition of
``effects of the action'' and other provisions in determining whether a
proposed NWP activity ``may affect'' listed species or designated
critical habitat, and for initiating ESA section 7 consultation for
those proposed activities where the district engineer makes a ``may
affect'' determination. If ESA section 7 consultation is required for
activities authorized by NWPs 12, 57, and 58, the Corps and U.S. FWS
and/or NMFS work together on a comprehensive review of the overall
project in accordance with the definition of ``effects of the action''
and other provisions of 50 CFR part 402, including the 2019 amendments
the U.S FWS and NMFS made to those regulations (see 84 FR 44976). For
ESA section 7 purposes where the Corps has a limited regulatory role
under the Clean Water Act and/or Section 10 of the Rivers and Harbors
Act of 1899, the Corps, with the assistance of the permit applicant,
can provide the U.S. FWS or NMFS with a biological assessment that
evaluates the larger project as a whole but that clearly distinguishes
between areas and effects subject to the Corps' jurisdiction and areas
and effects outside of its jurisdiction. If the proposed activity
requires formal ESA section 7 consultation, the U.S. FWS and NMFS can
issue an incidental take statement for a biological opinion where, in
accordance with ESA section 7(b)(4)(iv) they can assign responsibility
of specific terms and conditions of the incidental take statement to
the Corps, the applicant, or both taking into account their respective
roles, authorities, and responsibilities (see 84 FR 44977).
A few commenters said that it is likely activities are occurring
that are not in compliance with general condition 18 because the Corps
does not require PCNs for all activities. One commenter stated, with
regard to ESA-listed species, PCNs should not only include the
immediate area, rather the entire area impacted by NWP activities,
which must be consulted on programmatically with the U.S. FWS. This
commenter provided an example of studies have shown that pollutants and
sediments can impact critically imperiled mussels up to 10 river miles
from the impact location and said that ESA section 7 consultations
should include the evaluation of 10 river miles of potential effects
from the NWP impact location and analyses of cumulative effects as
well.
In order to obtain NWP authorizations, project proponents must
comply with all terms and conditions of the NWPs (see 33 CFR 330.1(c)),
including general condition 18. If a project proponent does not comply
with the requirements of general condition 18, including the PCN
requirements in paragraph (c) of that general condition, the activity
is not authorized by an NWP. When determining whether a proposed NWP
activity may affect listed species or designated critical habitat, the
district engineer applies the regulations issued by the U.S. FWS and
NMFS at 50 CFR part 402, including the definition of ``effects of the
action'' and other provisions the determine the scope of the ESA
section 7 consultation and analysis of effects or consequences
This general condition is adopted with the modifications discussed
above.
GC 19. Migratory Birds and Bald and Golden Eagles. The Corps
proposed to revise the wording of this general condition to clarify
that members of the regulated public should determine for themselves,
with the assistance of the U.S. Fish and Wildlife Service, what
``take'' permits, if any, they might require under the Migratory Bird
Treaty Act or the Bald and Golden Eagle Protection Act. This General
Condition makes clear that Project Proponents are responsible for
complying with the Migratory Bird Treaty Act and the Bald and Golden
Eagle Protection Act, including obtaining any ``take'' permits that may
be required under the U.S. Fish and Wildlife Service's regulations
issued under those statutes.
Several commenters expressed support for making no changes to this
general condition. One commenter noted that even though the Solicitor's
Opinion has been vacated, the Corps should move text from the preamble
to the general condition if reforms to the Migratory Bird Treaty Act
are finalized by the administration before the final NWPs are issued.
One commenter said that applicants should be encouraged to coordinate
with wildlife agencies. Several commenters stated that reference to the
Solicitor's Opinion in the preamble should be stricken because it was
recently vacated by a federal district court.
The text of the general condition is sufficient to address the
Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act
without moving text from the preamble of the proposed rule to the
general condition. Project proponents can coordinate their proposed
projects with federal and state wildlife agencies. There is no need to
strike the text that was in the preamble to the 2020 Proposal because
it was background used to solicit public comment, and it was current at
the time the proposal was published in the Federal Register.
This general condition is adopted as proposed.
GC 20. Historic Properties. The Corps proposed to modify paragraph
(c) of this general condition to state that the district engineer's
identification efforts for historic properties shall be commensurate
with potential impacts. The Corps also proposed to modify paragraph (d)
of this general condition to inform non-federal permittees that if pre-
construction notification is required under paragraph (c) of this
general condition, then he or she shall not begin the NWP activity
until the district engineer has determined the proposed activity has no
potential to cause effects to historic properties or has completed NHPA
section 106 consultation. Paragraph (d) requires the district engineer
to notify the non-federal applicant within 45 days of receipt of a
complete PCN whether NHPA section 106 consultation is required.
Several commenters expressed support for the proposed changes to
this general condition. A few commenters suggested adding language to
the general condition to require disclosure of the qualifications of
the person who would make an effect determination for the purposes of
Section 106 of the National Historic Preservation Act (NHPA). That
individual would need to satisfy the Secretary of the Interior's
Standards for Professional Qualifications in Archaeology and Historic
Preservation.
[[Page 2826]]
The Corps does not believe it would be appropriate to add text to
this general condition to require disclosure of the qualifications of
people making effects determinations for the purposes of section 106 of
the NHPA. Effect determinations may be made by a variety of agency
officials, including Corps district staff.
Many commenters stated that this general condition does not comply
with the NHPA and does not satisfy the Corps Section 106 obligations
with regards to the NWPs as it unlawfully delegates its Section 106
responsibilities to non-federal permittees and establishes a review
process that is not consistent with the Advisory Council on Historic
Preservation's (ACHP's) regulations at 36 CFR part 800. A few
commenters said that this general condition should not reference
Appendix C to 33 CFR part 325, because Appendix C has been determined
by the federal courts, the ACHP, and other federal agencies to be
unlawful. One commenter expressed support for the Corps' reliance on
Appendix C and its interim guidance, stating that they are generally
consistent with the ACHP's regulations.
This general condition does not delegate the Corps' section 106
responsibilities to permit applicants. The responsibility for making
effect determinations under section 106 of the NHPA for NWP activities
falls to the district engineer. For non-federal permittees, paragraph
(c) of general condition 20 requires the submission of a PCN for a
proposed activity that might have the potential to cause effects to
historic properties. The Corps' regulations for complying with section
106 of the NHPA are found at Appendix C to 33 CFR part 325. Appendix C
remains in effect as a counterpart regulation to 36 CFR part 800, and
no federal court has invalidated Appendix C.
A few commenters objected to this general condition, saying that it
encourages applicants to consult with State Historic Preservation
Officers (SHPOs), Tribal Historic Preservation Officers (THPOs) and
tribes. These commenters said that the Corps cannot delegate its tribal
consultation obligations to applicants. One commenter stated that the
proposed changes to general condition 20 will impact Native American
cultural resources.
Paragraph (c) of this general condition encourages permit
applicants to seek assistance from SHPOs, THPOs, and designated tribal
representatives to help ensure compliance with this general condition.
Seeking assistance is not equivalent to conducting consultation.
Section 106 consultation remains the responsibility of the Corps. The
requirements of general condition 20, plus the changes being made in
this final rule, will ensure that section 106 consultation occurs for
NWP activities that have potential to cause effects to Native American
cultural resources that meet the definition of ``historic property'' in
Section F, Definitions.
Several commenters said that the proposed change to paragraph (c),
which states that the district engineer's identification efforts for
historic properties shall be commensurate with potential impacts,
should be further revised for clarity. A few commenters expressed
opposition to this proposed change to paragraph (c) and requested that
it be removed in the final rule. Several commenters stated that the
text in paragraph (c) should make clear that the evaluation is only
associated with the extent of the Corps' jurisdiction. One commenter
said that the proposed change gives the Corps justification to decline
to identify certain historic properties if the district engineer
determines that the property or properties will not be impacted by the
proposed activity. A few commenters opined that the Corps fails to
evaluate areas outside its jurisdiction, particularly with linear
projects, with is contrary to current regulations.
The change to paragraph (c) regarding the district engineer's
identification efforts for historic properties is consistent with the
ACHP's regulations at 36 CFR 800.4(b)(1) regarding the level of
identification efforts. Section 800.4(b)(1) states that the federal
agency should take into account the ``magnitude and nature of the
undertaking and the degree of federal involvement, the nature and
extent of potential effects on historic properties, and the likely
nature and location of historic properties within the area of potential
effects.'' When evaluating an NWP PCN, the district engineer will
identify the permit area in accordance with the criteria in paragraph
1(d) of Appendix C to 33 CFR part 325. The Corps will evaluate direct
and indirect effects caused by the proposed NWP activity. If an
historic property is not directly or indirectly affected by the
proposed NWP activity, the Corps does not have the authority to prevent
effects to historic properties caused by activities outside of its
control and responsibility.
One commenter recommended that the Corps adhere to the 45-day
review time or as an alternative change paragraph (c) of this general
condition so that the district engineer's review of the PCN does not
exceed 90 days. One commenter stated that language requiring an
applicant to continue to wait beyond 45 days if they have not heard
back from the Corps creates the potential for an indefinite delay. This
commenter suggested adding a requirement for the district to establish
a deadline for notifying the applicant on whether NHPA section 106
consultation is required.
Paragraph (d) of general condition 20 states that for non-federal
permittees, the district engineer will notify the prospective permittee
within 45 days of receipt of a complete PCN whether NHPA section 106
consultation is required. The section 106 consultation process may take
longer than 45 days. The NWP verification cannot be issued and the
project applicant cannot proceed with the proposed activities under
Corps jurisdiction until the section 106 consultation process has been
completed.
A few commenters said that Corps districts often override the
permittees' determination as to whether a PCN is required for a
proposed activity under paragraph (c). One commenter recommended
modifying or revising paragraph (a) of general condition 20 in a manner
consistent with paragraph (a) of general condition 18 to focus on the
threshold that triggers the requirement for section 106 consultation,
rather than determinations made by district engineers once a PCN is
submitted. One commenter recommended timely review of scopes of work
and requested that the Corps make final determinations regarding scopes
of review and not allow any revisions to those determinations.
For an NWP activity, it is ultimately the district engineer's
responsibility to determine compliance with section 106 of the NHPA. As
additional information is revealed during the review of a PCN or during
section 106 consultation, it may be necessary to change the scope of
review to ensure compliance with the requirements of section 106 of the
NHPA. The Corps has modified paragraph (a) of this general condition to
state that ``no activity is authorized under any NWP which may have the
potential to cause effects to properties listed, or eligible for
listing, in the National Register of Historic Places until the
requirements of Section 106 of the National Historic Preservation Act
(NHPA) have been satisfied.''
One commenter said that clarification is needed on who are the non-
federal permittees that need to submit PCNs under paragraph (c). One
commenter remarked that the terms ``might have the potential to cause''
and ``potentially
[[Page 2827]]
eligible'' are vague terms and that Corps districts are applying these
requirements inconsistently and more expansively than appropriate. One
commenter said that the ``might have the potential'' standard is a
higher threshold than the threshold set forth in the ACHP's regulations
at 36 CFR part 800.
As a general matter, a non-federal permittee is a permittee that is
not a federal agency. There may be limited circumstances where a non-
federal agency might be considered as having NHPA section 106
obligations similar to those of a federal agency. For example, the
Federal Highway Administration may assign a state Department of
Transportation the responsibility for complying with non-NEPA
environmental statutes such as the NHPA. The purpose of the ``might
have the potential to cause effects'' threshold in paragraph (c) of
this general condition is to require submittal of PCNs for proposed NWP
activities that might have a possibility of causing effects to historic
properties, so that the district engineer can determine whether section
106 consultation is required for a proposed NWP activity. ``Potentially
eligible'' is another threshold that is intended to provide an
opportunity for further review to determine whether a historic property
is present. These thresholds cannot be precisely defined, and involve
some degree of subjectivity.
One commenter stated that paragraph (b) of this general condition
improperly designates other federal agencies as the lead with respect
to Section 106 without their agreement. This commenter further noted
that this might be problematic given the proposal not to require PCNs
from federal permittees for proposed activities that might have the
potential to cause effects to historic properties.
Other federal agencies have their own obligations to comply with
section 106 of the NHPA. If a proposed NWP activity being undertaken by
another federal agency requires a PCN, paragraph (b) of this general
condition requires the federal permittee to submit appropriate
documentation demonstrating compliance with the requirements of section
106. After reviewing that documentation, the district engineer may
notify the federal permittee that additional section 106 consultation
may be necessary. Non-federal and federal permittees have different
thresholds under this general condition because their responsibilities
under section 106 are different.
This general condition is adopted with the modifications discussed
above.
GC 21. Discovery of Previously Unknown Remains and Artifacts. The
Corps did not propose any changes to this general condition. One
commenter recommended reissuance of the general condition with no
additional restrictive provisions.
This general condition is adopted as proposed.
GC 22. Designated Critical Resource Waters. The Corps did not
propose any changes to this general condition. One commenter
recommended revising this general condition to include state designated
critical resource waters rather than deferring to Corps district
engineers to designate certain waters at a later date. One commenter
recommended adding proposed new NWPs C and D to the list of NWPs in
paragraph (a) of this general condition. This commenter also suggested
adding proposed new NWPs A and B to the list of NWPs in paragraph (b)
of this general condition. Two commenters said that if the Corps
removes the PCN requirements for federal permittees, federal agencies
should still be required to submit PCNs for proposed activities in
designated critical resource waters.
After providing notice and an opportunity for public comment, the
Corps is continuing to require the long-standing practice of allowing
district engineers to add specific waters to this general condition.
States that want waters of particular environmental or ecological
significance to be subjected to this general condition should provide
their recommendations to the appropriate district engineer for
consideration. Since NWP 12 has been in paragraph (a) of this general
condition since it was first adopted in 2000 (65 FR 12872), for
consistency the Corps has added new NWPs 57 and 58 to this general
condition. New NWPs 55 (seaweed mariculture activities) and 56 (finfish
mariculture activities) require PCNs for all activities, so it is
unnecessary to add these NWPs to the list of NWPs in paragraph (b) of
this general condition. In addition, the Corps is retaining PCN
requirements for federal permittees.
This general condition is adopted with the modifications discussed
above.
GC 23. Mitigation. The Corps proposed to modify paragraph (d) of
this general condition to establish a threshold for requiring
compensatory mitigation for losses of stream bed that is similar to the
threshold for wetlands in paragraph (c) of this general condition. The
Corps proposed to add a \1/10\-acre threshold for requiring
compensatory mitigation for losses of stream beds that require pre-
construction notification, unless the district engineer determines on a
case-by-case basis that compensatory mitigation should not be required
because other forms of mitigation would be more environmentally
appropriate and issues an activity-specific waiver of this requirement.
A few commenters expressed support for the changes to this general
condition. One commenter objected to the proposed changes and
recommended that this general condition be reissued with no changes.
One commenter stated that compensatory mitigation should not be
required when compensatory mitigation is required by other federal or
state laws, rules, or regulations. Another commenter said that the
Corps should focus on improving consistency between districts on when
compensatory mitigation is required for NWP activities.
Changes to this general condition are necessary to address the
removal of the 300 linear foot limit for losses of stream bed under
NWPs 21, 29, 39, 40, 42, 43, 44, 50, 51, and 52. District engineers
impose compensatory mitigation requirements on specific activities
authorized by NWPs to ensure that those activities result in no more
than minimal individual and cumulative adverse environmental effects.
If a proposed NWP activity is regulated by another federal agency or a
state, tribal, or local agency, and that agency requires compensatory
mitigation for that proposed activity, the district engineer may
consider those compensatory mitigation requirements before determining
whether additional compensatory mitigation is required for that
activity. The Corps should not be imposing duplicative compensatory
mitigation requirements when the resource concerns are already being
addressed by another federal, tribal, state, or local agency. The Corps
believes that federal and state regulatory programs should complement
rather than duplicate one another (see 33 CFR 320.1(a)(5). Since
aquatic resources can vary substantially across the country, different
Corps districts may establish different compensatory mitigation
requirements.
One commenter disagreed that project proponents design projects to
minimize losses of waters of the United States to qualify for NWP
authorizations to avoid the cost of providing compensatory mitigation
to offset the authorized losses. One commenter said that other forms of
mitigation used for NWP activities should include best management
practices, minimization measures, activities that result in improvement
of wetland and stream habitat, and actions that improve water quality.
Another commenter disagreed
[[Page 2828]]
that best management practices and other forms of mitigation are more
environmentally preferable forms of mitigation, and that best
management practices should be implemented during the design,
construction, and operations stages of a project.
The data the Corps collects on the impacts to waters of the United
States authorized by the NWPs shows that 82 percent of verified impacts
authorized by NWPs in 2018 are less than \1/10\-acre (see Figure 5.1 of
the Regulatory Impact Analysis for this final rule). During 2018, only
5% of the verified impacts authorized by NWPs resulted in impacts to
0.25 acre to 0.5 acre. For those NWPs that have a qualitative limit in
acres, a \1/2\-acre limit is the most common acreage limit. The small
percentage of verified NWP activities that impact between 0.25 and 0.5
acre compared to the much larger percentage of verified NWP activities
that impact less than \1/10\-acre demonstrates the reduction of impacts
(i.e., minimization) that is incentivized by general condition 23.
District engineers determine the compensatory mitigation requirements
for specific NWP activities, and can require forms of mitigation other
than compensatory mitigation to ensure that the authorized NWP activity
results in no more than minimal individual and cumulative adverse
environmental effects. The use of other forms of mitigation is
consistent with the watershed approach to compensatory mitigation
described in the Corps' regulations at 33 CFR 332.3(c). The use of best
management practices and other forms of mitigation may be effective at
reducing adverse environmental effects so that compensatory mitigation
is not necessary to ensure that an NWP activity results in only minimal
individual and cumulative adverse environmental effects.
A couple of commenters said that compensatory mitigation cannot
legally be used to make minimal adverse effects determinations and that
Section 404(e) of the Clean Water Act does not state that mitigation
will be considered to ensure activities would cause only minimal
adverse environmental effects. These commenters objected to the use of
compensatory mitigation to allow more impacts to waters and wetlands.
One commenter stated that the Corps has not provided any scientific or
factual evidence to conclude that compensatory mitigation helps ensure
that NWP activities do not result in more than minimal adverse
environmental effects. A couple of commenters said that compensatory
mitigation does not adequately or fully replace wetland or stream bed
losses. Several commenters said they do not support the use of
mitigation as a means to allow more impacts and justify findings of no
more than minimal adverse environmental effects.
The use of compensatory mitigation and other forms of mitigation to
ensure that activities authorized by an NWP result in no more than
minimal individual and cumulative adverse environmental effects is
codified in the Corps' NWP regulations at 33 CFR 330.1(e)(3). Section
404(e) of the Clean Water Act does not prescribe how the Corps is to
ensure that the categories of activities authorized by general permits
such as the NWPs will cause only minimal adverse environmental effects
when performed separately, and will have only minimal cumulative
adverse effect on the environment. Therefore, the Corps has discretion
on how to comply with the requirement in the statute. Wetlands can be
restored to improve the degree of ecological functions they provide
(e.g., NRC 2001), to offset wetland losses authorized by the NWPs and
other types of DA permits. Streams can also be restored to increase the
degree of ecological functions they provide (e.g., Wohl et al. 2015),
which can also be used to offset losses of stream functions caused by
activities authorized by NWPs and other types of DA permits.
One commenter stated that this general condition should require
compensatory mitigation for all losses of wetlands, special aquatic
sites, and stream beds authorized by an NWP, not just those losses
exceeding \1/10\-acre that require PCNs. One commenter said that
current compensatory mitigation requirements only replace, not improve,
aquatic resources, and to protect tribal treaty rights, the Corps
should require improvements of aquatic resources to ensure the
successful recovery of salmon.
Compensatory mitigation and other forms of mitigation are only
required by district engineers when it is necessary to ensure that NWP
activities result in no more than minimal individual and cumulative
adverse environmental effects (see 33 CFR 330.1(e)(3)), and the Corps
has determined that \1/10\-acre is an appropriate threshold with
respect to wetland mitigation. Compensatory mitigation can be provided
through the restoration, enhancement, establishment, and protection of
aquatic resources to offset losses of those functions caused by
activities authorized by the NWPs and other types of DA permits. A
compensatory mitigation credit is a unit of measure (e.g., a functional
or areal measure or other suitable metric) representing the accrual or
attainment of aquatic functions at a compensatory mitigation site (see
33 CFR 332.2). Compensatory mitigation required for NWP activities can
help improve aquatic resources that may assist in the successful
recovery of salmon.
One commenter said the Corps relies too heavily on mitigation banks
and in-lieu fee programs to provide compensatory mitigation despite a
large body of scientific evidence that concluded that wetland banks are
ineffective and poorly monitored. A couple of commenters stated that
mitigation banks and in-lieu fee programs do not replace lost functions
and values at impact sites. One commenter said that the Corps relies on
unrealized mitigation requirements to allow significant environmental
harm to occur under the NWP program and that previous reports from the
National Research Council and the Government Accountability Office have
shown that mitigation under the NWP program has not proven successful
and therefore, does not compensate for lost wetlands.
Regulations for the establishment and use of mitigation banks and
in-lieu fee programs to provide compensatory mitigation for activities
authorized by the NWPs and other forms of DA authorization were issued
by the Corps in 2008 (see 73 FR 19594). The 2008 rule establishes
establish performance standards and criteria for the use of permittee-
responsible compensatory mitigation, mitigation banks, and in-lieu
programs to improve the quality and success of compensatory mitigation
projects for activities authorized by Department of the Army permits.
The 2008 mitigation rule incorporated many of the recommendations made
by the National Research Council in its 2001 titled ``Compensating for
Wetland Losses Under the Clean Water Act'' to improve the ecological
outcomes of wetland compensatory mitigation projects. The 2005
Government Accountability Office report titled ``Wetlands Protection:
Corps of Engineers Does Not Have an Effective Oversight Approach to
Ensure That Compensatory Mitigation Is Occurring'' also included
recommendations for improving the Corps' oversight and outcomes of
compensatory mitigation projects performed by permittees, mitigation
banks, and in-lieu-fee program sponsors, and the Corps incorporated
those recommendations in the 2008 mitigation rule.
One commenter said the NWP program should not be used to authorize
activities that requiring compensatory mitigation and that project
proponents should have to apply for individual
[[Page 2829]]
permits for activities requiring compensatory mitigation. One commenter
stated that using mitigation to reduce impacts below a threshold of
significance violates the National Environmental Policy Act.
The use of compensatory mitigation for NWP activities is an
important tool for authorizing activities that have no more than
minimal individual and cumulative adverse environmental effects by NWP.
Requiring individual permits for any NWP activity that requires
compensatory mitigation would not provide any additional environmental
protection because the ecological outcomes of compensatory mitigation
projects is more dependent on site selection, planning, and
implementation, as well as monitoring and adaptive management to
address deficiencies in the compensatory mitigation project that impede
the ecological success of that project. The type of DA authorization
used to authorize a regulated activity is not linked to the ecological
outcomes of compensatory mitigation projects. Under the Council on
Environmental Quality's regulations for implementing the National
Environmental Policy Act, mitigation can be used to reduce project
impacts so that they are not significant (see 40 CFR 1501.6(c)).
A couple commenters recommended that an economic analysis be
performed to evaluate the economic effects of the proposed changes to
this general condition, to assess the costs of the additional time and
resources needed to overhaul stream credit programs, evaluate losses to
mitigation providers and contractors, and the capacity to determine if
the Corps can reasonably implement the proposed changes.
The changes to this general condition do not require an overhaul of
stream credit programs. Compensatory mitigation credits, including
stream credits, can be quantified in acres, linear feet, functional
assessment units, or other suitable metrics of particular resource
types (see 33 CFR 332.8(o)(1)). The preamble to the 2008 mitigation
rule states that district engineers retain the discretion to quantify
stream impacts and required compensatory mitigation in terms of area or
other appropriate units of measure (see 73 FR 19633). This discretion
also applies to the issuance of the NWPs by Corps Headquarters, to
determine appropriate units of measure for efficient administration of
the NWP program. Existing inventories of stream credits can be used to
provide compensatory mitigation for losses of stream bed authorized by
these NWPs. For those current inventories of stream credits quantified
in linear feet or other linear metrics, the permittee and mitigation
provider can engage in discussions to determine how many linear feet of
stream credits are roughly proportional to the area of stream bed
filled or excavated as a result of an activity authorized by an NWP.
Each mitigation bank and in-lieu fee project has an approved mitigation
plan, and that mitigation plan can be used to estimate how many linear
feet of stream credits might be used to offset a specified number of
acres or square feet filled or excavated as a result of an NWP
activity. Over the years, there have been numerous changes to the Corps
Regulatory Program, and each of those changes require some adjustment
by Corps personnel, permit applicants, consultants, contractors,
mitigation providers, and other people.
One commenter recommended NWPs and/or regional conditions
authorizing the use of compensatory mitigation, mitigation banks, and/
or in-lieu fee programs be withdrawn. One commenter said that this
general condition should be modified to state that out-of-kind
mitigation is prohibited for losses of designated critical resource
waters identified in general condition 22.
Division engineers can add regional conditions to the NWPs to
establish lower thresholds for stream compensatory mitigation, and for
the use of mitigation banks, in-lieu fee programs, and permittee-
responsible mitigation for activities authorized by NWPs. Out-of-kind
mitigation may be beneficial to designated critical resource waters.
Therefore, the Corps declines to make the recommended change to general
conditions 22 or 23.
Several commenters said that this general condition should be
modified to require applicants to take all practicable steps to avoid
and minimize effects to waters of the United States. One commenter
stated that avoidance and minimization of waters of the United States
during the planning and siting phases of project development are not
appreciated or considered by regulatory agencies.
Paragraph (a) of general condition 23 already requires the NWP
activity to be designed and constructed to avoid and minimize adverse
effects, both temporary and permanent, to waters of the United States
to the maximum extent practicable at the project site (i.e., on site).
A description of the mitigation measures being undertaken by the
project proponent, including avoidance and minimization on the project
site, in the PCN can assist the district engineer in his or her
decision whether the proposed activity qualifies for NWP authorization.
One commenter expressed support for allowing the district engineer
to waive compensatory mitigation requirements for wetland losses if she
or he makes an activity-specific determination that other forms of
mitigation would be environmentally preferable. One commenter requested
the Corps identify, at a national level, the minimum amount of
compensatory mitigation required to offset resource losses. Several
commenters said that compensatory mitigation should be required
consistently for all NWPs with areal and linear thresholds.
The Corps has retained the ability of district engineers to waive
compensatory mitigation requirements for wetland losses when they
determine that the proposed activity, without wetland compensatory
mitigation, will result in no more than minimal individual and
cumulative adverse environmental effect. Compensatory mitigation
decisions are made on a case-by-case basis by district engineers, so it
would be inappropriate to establish national minimums for compensatory
mitigation requirements, or for all NWPs that have quantitative limits.
One commenter stated that paragraph (c) should be modified to allow
for protection, restoration, or enhancement of areas next to wetlands
as compensatory mitigation, similar to the proposed language in
paragraph (d). A couple of commenters said that a one-for-one impact-
to-compensation ratio only works if all compensatory mitigation efforts
are successfully implemented and the Corps monitors and enforces
compensatory mitigation requirements. These commenters recommended
modifying this general condition to clarify how the ecological outcomes
of compensatory mitigation projects would be improved and how the Corps
would ensure that no-net-loss of aquatic resources is achieved.
The Corps' compensatory mitigation regulations at 33 CFR 332.3(i)
allow district engineers to require the restoration, establishment,
enhancement, and preservation, as well as the maintenance, of riparian
areas and/or buffers around aquatic resources where necessary to ensure
the long-term viability of those resources. This provision also applies
to all types of DA permits, including the NWPs. There is no need to
explicitly state this information in the text of the general condition.
The Corps' compensatory mitigation regulations requires monitoring of
compensatory mitigation projects, and for district engineers to take
action to ensure that compensatory
[[Page 2830]]
mitigation projects achieve their objectives and offset the losses of
waters of the United States. Adaptive management may be required to
ensure that those compensatory mitigation objectives are met. The
ecological outcomes of compensatory mitigation projects are more
appropriately addressed on a case-by-case basis, through compliance
efforts by district engineers.
A couple commenters supported the continued use of a \1/10\-acre
threshold for requiring compensatory mitigation and said that the
threshold has been effective in encouraging avoidance and minimization
of adverse effects to wetlands. Several commenters said that a one-for-
one impact-to-compensation ratio should be required to compensate for
all wetland losses to ensure no-net-loss, not just those losses that
exceed \1/10\-acre. Several commenters remarked that the proposed \1/
10\-acre threshold to require compensatory mitigation for losses of
wetlands and stream bed does not achieve a goal of no-net-loss of
aquatic resources. One commenter said no-net-loss should not be applied
to areas that have been previously and heavily modified.
The Corps is retaining the \1/10\-acre threshold for wetland
compensatory mitigation in paragraph (c) of this general condition
based on its experience administering the program. There is no
requirement in Section 404 or the Clean Water Act, the Corps'
regulations at 33 CFR parts 320 to 332, or the U.S. EPA's 404(b)(1)
Guidelines for no net loss of wetlands or other types of aquatic
resources. For all DA permits, including the NWPs, compensatory
mitigation requirements are determined on a case-by-case basis.
Compensatory mitigation may be required by district engineers to ensure
that an activity that requires authorization under section 404 of the
Clean Water Act and/or sections 9 or 10 of the Rivers and Harbors Act
of 1899 is not contrary to the public interest (see 33 CFR 332.1(d)).
Compensatory mitigation for unavoidable impacts may be required to
ensure that an activity requiring a section 404 permit complies with
the Section 404(b)(1) Guidelines (see 33 CFR 332.1(c)(3)).
One commenter said that paragraph (c) of this general condition
should be modified to allow mitigation bank credits to be used at a
one-for-one ratio rather than performing a functional analysis. A
commenter stated that \1/10th\-acre may be too restrictive of a
compensatory mitigation threshold in some Corps districts or watersheds
and compensatory mitigation may not be required to achieve no more than
minimal adverse environmental effects for certain NWP activities.
Another commenter suggested the applicant be required to provide
documentation of credit availability or credit reservation if proposing
to satisfy compensatory mitigation requirements with credits from a
mitigation bank. One commenter said that this general condition should
be modified to state that mitigation bank credits are preferred where
practicable, and to elucidate that mitigation banks are not practicable
in the State of Alaska.
Paragraph (c) of this general condition does not require the use of
a functional analysis to determine whether mitigation bank credits can
be used to provide compensatory mitigation for an NWP activity.
District engineers have the discretion to waive the compensatory
mitigation requirement for losses of greater than \1/10\-acre of
wetlands, or to require another form of mitigation to ensure that the
NWP activity results in no more than minimal individual and cumulative
adverse environmental effects. If the district engineer determines that
compensatory mitigation is required for a proposed NWP activity, the
applicant can propose to use mitigation bank credits or in-lieu fee
program credits to fulfill the compensatory mitigation requirement. The
district engineer can require the applicant to provide a statement of
credit availability, so that the applicant does not have to prepare a
mitigation proposal for a permittee-responsible mitigation project. The
framework for evaluating compensatory mitigation options, that is the
use of mitigation bank credits, in-lieu fee program credits, or
permittee-responsible mitigation, is provided in the Corps' regulations
at 33 CFR 332.3(b). Mitigation banks can be practicable in the State of
Alaska.
One commenter requested clarification on PCN and compensatory
mitigation requirements for NWP activities involving mechanized land
clearing in forested wetlands for utility line rights-of-way since
paragraph (i) of general condition 23 states that compensatory
mitigation may be required for activities that convert a forested or
scrub-shrub wetland to an herbaceous wetland. A commenter said that
compensatory mitigation should be provided on-site or in the sub-basin
where impacts occur.
Consistent with paragraph (i) of this general condition, if a
proposed NWP activity involves mechanized land clearing in a forested
wetland, and it requires a PCN, the district engineer can require
compensatory mitigation to ensure the proposed activity result in no
more than minimal individual and cumulative adverse environmental
effects. For an NWP activity that requires compensatory mitigation, the
district engineer will determine whether on-site or off-site
compensatory mitigation is required, and the appropriate geographic
scale for consideration of off-site compensatory mitigation options.
One commenter said that general condition 23 should clearly state
whether compensatory mitigation would or would not be required for
wetland and stream bed losses for NWP activities that do not require
PCNs. One commenter recommended that compensatory mitigation be
provided for all losses of wetland or stream bed that exceed \1/10\-
acre, not just those losses requiring PCNs. A few commenters stated
that compensatory mitigation for wetland and stream bed losses should
be required at ratios greater than one-for-one to account for temporal
loss and the difficulty of replacing wetlands and stream bed, and to
ensure that habitat is recovered at a greater degree than it is being
lost. One commenter said that there is no basis for wetlands and
streams to have the same \1/10\-acre compensatory mitigation threshold.
For those NWP activities that do not require PCNs, compensatory
mitigation is not required because the district engineer is not
notified of those activities and cannot add permit conditions to the
NWP authorization in accordance with 33 CFR 332.3(k). The district
engineer determines the appropriate amount of compensatory mitigation
in accordance with the Corps' regulations at 33 CFR 332.3(f). As
discussed below, in response to comments received on the proposed rule,
the Corps is changing the threshold in paragraph (d) of this general
condition from \1/10\-acre to \3/100\-acre.
A few commenters stated that compensatory mitigation should only be
required for the losses of jurisdictional wetlands and streams and
compensatory mitigation should not be required for losses of ephemeral
stream bed or losses of other non-jurisdictional waters. Several
commenters said that compensatory mitigation should only be required
for permanent impacts and that temporary impacts should not be counted
in the \1/10\-acre threshold. One commenter suggested that this general
condition should be modified to clarify if the \1/10\-acre threshold
would be applied individually or cumulatively in cases where both
stream bed and wetlands would be lost. Several commenters said the \1/
10\-acre threshold in paragraphs (c) and (d) should be applied
cumulatively so that any
[[Page 2831]]
combination of wetland and stream losses exceeding \1/10\-acre would
require compensatory mitigation.
Since ephemeral streams are excluded from Clean Water Act
jurisdiction, (see 33 CFR 328.3(b)(3)), NWP authorization is not
applicable to ephemeral streams. Compensatory mitigation is not
required for losses of ephemeral stream bed, or for losses of any other
non-jurisdictional waters. The \1/10\-acre and \3/100\-acre thresholds
in paragraphs (c) and (d) of this general condition apply to losses of
waters of the United States, as that term is defined in Section F of
the NWPs (Definitions). These thresholds apply to single and complete
projects authorized by the NWPs.
Several commenters said it is important to maintain the Corps'
flexibility as proposed to allow district engineers to determine that
other forms of mitigation are appropriate or to waive mitigation
requirements for specific NWP activities. Several commenters objected
to allowing district engineers to waive compensatory mitigation
requirements. One commenter said that if federal agencies are not
required to submit PCNs, those agencies would not have to provide
compensatory mitigation for wetland or stream bed losses that exceed
\1/10\-acre because the \1/10\-acre threshold proposed in paragraphs
(c) and (d) only applies to NWP activities that require PCNs. Several
commenters said that paragraphs (c) and (d) should be modified to state
that advanced mitigation is preferred.
The general condition retains flexibility for district engineers to
determine the appropriate mitigation for a particular NWP activity to
ensure that the activity causes no more than minimal individual and
cumulative adverse environmental effects. After the district engineer
reviews a PCN, he or she may determine that no mitigation is necessary
for the proposed activity to be authorized by an NWP. For these 16
final NWPs, federal agencies are subjected to the same PCN requirements
as non-federal permittees. They are also subject to the mitigation
requirements in this general condition. Advance compensatory mitigation
can be used to satisfy compensatory mitigation requirements added to
NWP authorizations by district engineers.
One commenter voiced support for the addition of a \1/10\-acre
threshold for requiring compensatory mitigation for losses of stream
beds that require pre-construction notification. Another commenter
expressed support for the addition of a compensatory mitigation
threshold for stream bed losses represented in either linear feet or
acres. One commenter stated that compensatory mitigation for stream bed
losses should result in net gains in area or functions. A few
commenters said that headwater streams are fundamentally different and
offer different services than non-tidal wetlands and therefore should
not be regulated the same. Additionally, minimal adverse environmental
effects are different for distinct aquatic resources. One commenter
opposed the elimination of ``other open waters'' from paragraph (d) and
said it would create uncertainty for when compensatory mitigation would
be required for losses of other open waters. A couple commenters said
that reducing compensatory mitigation requirements also reduces the
incentive to minimize impacts.
Stream compensatory mitigation projects are expected to result in
increases in stream functions, since the purpose of compensatory
mitigation is to offset unavoidable adverse impacts which remain after
all appropriate and practicable avoidance and minimization has been
achieved. Stream compensatory mitigation projects produce credits that
represent the accrual or attainment of stream functions at a
compensatory mitigation site, consistent with the definition of
``credit'' in the Corps' regulations at 33 CFR 332.2. While headwater
streams exhibit some differences in structure and function than
downstream streams in a tributary network, when those headwater streams
are considered waters of the United States, they are subjected to the
same regulatory requirements as other waters of the United States.
Headwater streams have no special status under the Clean Water Act or
its implementing regulations, including the 404(b)(1) Guidelines issued
by the U.S. EPA. The only streams that are special aquatic sites under
the 404(b)(1) Guidelines are riffle and pool complexes (see subpart E
of 40 CFR part 230). When reviewing a PCN for a proposed activity that
may cause the loss of headwater stream bed, the district engineer will
consider the functions being performed by the headwater streams. The
Corps proposed to redesignate paragraph (d) of the 2017 general
condition 23 as paragraph (e) of the 2021 general condition 23, so it
did not propose to remove ``other open waters'' from the paragraph that
discusses the use of riparian areas next to open waters as compensatory
mitigation for NWP activities. The Corps did not propose to reduce any
compensatory mitigation requirements.
Several commenters stated the \1/10\-acre stream compensatory
mitigation threshold is too broad to apply nationally. One commenter
recommended establishing thresholds for requiring compensatory
mitigation for stream bed losses through regional conditions instead of
general condition 23 to account for the regional variability of streams
across the United States. Several commenters stated that implementation
of a \1/10\-acre threshold for stream compensatory mitigation does not
achieve a goal of no-net-loss of aquatic resources. A couple commenters
said that paragraph (d) allows for incremental losses of stream bed,
which is contrary to the Corps' no-net-loss objective and is
inconsistent with restoring habitat necessary to provide sustainable
fish populations. One commenter stated that reductions in the amount of
required mitigation to compensate for headwater stream losses would
have large impacts on downstream waters, including large rivers. One
commenter said that implementing a \1/10\-acre threshold for requiring
compensatory mitigation for stream bed losses would increase the
regulatory burden on downstream applicants due to declining water
quality.
Since the NWPs authorize activities across the country, paragraph
(d) of this general condition establishes a national threshold for
stream compensatory mitigation, but there is flexibility in the general
condition to allow district engineers to make activity-specific
determinations on whether stream compensatory mitigation should be
required for activities that result in the loss of stream bed. Division
engineers can add regional conditions to the NWPs to establish a lower
threshold for requiring stream compensatory mitigation. As discussed
above, there is no requirement for no net loss of stream bed in the
Clean Water Act or the Corps' regulations for implementing the Clean
Water Act. Previous versions of this general condition in prior NWP
rulemakings did not have a threshold for compensatory mitigation for
losses of stream bed. A stream compensatory mitigation threshold was
added to this general condition to provide an additional mechanism to
help ensure that activities authorized by the 10 NWPs from which the
300 linear foot limit for losses of stream bed was removed result in no
more than minimal individual and cumulative adverse environmental
effects. Similar to the \1/10\-acre wetland compensatory mitigation
threshold, this compensatory mitigation threshold for stream bed losses
is expected to provide incentives for project proponents to design
their
[[Page 2832]]
projects to minimize losses of stream bed, and help sustain downstream
functions and water quality.
One commenter said that stream compensatory mitigation should only
be required for new impacts associated with the maintenance or
replacement of previously authorized structures. Another commenter
stated that given the difficulties to achieve successful stream
mitigation, requiring compensatory mitigation for stream bed losses
greater than \1/10\-acre will be unrealistic in areas where permittee-
responsible mitigation is the only option available. A few commenters
suggested that thresholds reflect what would be required to ensure
activities result in only minimal adverse environmental effects. Many
commenters said that the \1/10\-acre threshold for requiring
compensatory mitigation for stream bed losses is too large for
headwater streams.
District engineers will determine on a case-by-case basis whether
to require compensatory mitigation for losses of stream bed authorized
by NWPs. When determining whether to require compensatory mitigation,
the district engineer will also consider practicability, including
whether permittee-responsible mitigation is likely to be ecologically
successful in offsetting the permitted impacts. As discussed below, the
Corps has changed the \1/10\-acre threshold to \3/100\-acre to account
for stream size.
One commenter said the compensatory mitigation requirement for
losses of stream bed greater than \1/10\-acre reduces the flexibility
of the district engineer in making compensatory mitigation decisions. A
few commenters objected to including a threshold for compensatory
mitigation for the loss of stream bed, stating that it may result in
unnecessary additional mitigation requirements and would not reduce
burdens on the regulated public. Several commenters said the \1/10\-
acre threshold for compensatory mitigation for stream bed losses or the
district engineer's determination to waive compensatory mitigation
requirements would individually and cumulatively would directly or
indirectly result in more than minimal adverse environmental effects.
The text of this general condition is written to provide district
engineers with substantial flexibility in determining whether
compensatory mitigation is required for NWP activities and what the
required compensatory mitigation should be for a particular NWP
activity. Corps districts have been requiring stream compensatory
mitigation for a number of years, so the changes to this general
condition will not impose additional burdens on the regulated public.
If the district engineer determines, after reviewing a PCN, that stream
compensatory mitigation is not necessary to ensure that the NWP
activity result in no more than minimal adverse environmental effects,
he or she will not require stream compensatory mitigation for that
activity.
Many commenters suggested requiring compensatory mitigation for
stream bed losses of 300 linear feet or more instead of the proposed
\1/10\-acre threshold. One commenter said that a linear foot threshold
is more appropriate than acreage and recommended revising paragraph (d)
to require compensatory mitigation for stream bed losses greater than
100 linear feet. One commenter recommended revising paragraph (d) to
require compensatory mitigation for stream bed losses greater than 150
linear feet. One commenter recommended changing paragraph (d) to
require compensatory mitigation for stream bed losses of \1/10\-acre or
300 linear feet. Many commenters said that the proposed \1/10\-acre
stream mitigation threshold would result in more impacts with less
compensatory mitigation being required. One commenter suggested using a
scaled approach for establishing a stream compensatory mitigation
threshold, such as a length threshold of five times the bankfull width
or five times the width between ordinary high water marks. This
commenter said a scaled approach would better account for variations in
headwater streams and large rivers, compared to a \1/10\-acre
threshold.
After evaluating the comments received in response to the proposed
modification of general condition 23, the Corps is changing the
threshold for stream compensatory mitigation in paragraph (d) from \1/
10\-acre to \3/100\-acre. This is consistent with the stream
compensatory mitigation threshold established in some Corps districts
under the 2017 NWPs and the compensatory mitigation threshold
recommended by several commenters. For the 2017 NWPs, a number of Corps
districts have regional conditions requiring compensatory mitigation
for losses of greater than 300 linear feet of stream bed. This is
consistent with the recommendation for a 300 linear foot threshold made
by many commenters in response to this proposed rule. The \3/100\-acre
threshold in paragraph (d) was calculated by estimating the average
width of stream fills (4 feet) authorized by the 2017 NWPs under the 10
NWPs and multiplying that figure by 300 linear feet. The average width
of stream filling or excavation was calculated from ORM2 data for NWP
verifications issued between March 19, 2017, and March 19, 2019, for
those NWP verifications where the average width of the stream fill or
excavation was recorded by Corps district staff. The \3/100\-acre
threshold is anticipated to result in similar stream compensatory
mitigation requirements for the NWPs in this final rule compared to the
2017 NWPs, and therefore is generally consistent with current agency
practice. A scaled approach for establishing a stream compensatory
mitigation threshold would add another level of complexity to a permit
program that is intended to regulate, with little delay or paperwork,
activities that result in minimal adverse environmental effects.
A few commenters said the \1/10\-acre threshold for stream losses
requiring compensatory mitigation is not scientifically supported or
lacks supporting analysis. A couple commenters said they do not agree
with the change in threshold from linear feet of impact to acres for
requiring compensatory mitigation for losses of stream beds that
require PCNs. A few commenters stated that the use of stream length
rather than acreage has been used in many programs as a basis for
determining mitigation credits to compensate for the loss of stream
bed, and that the \1/10\-acre threshold would create uncertainty and
additional costs for applicants, the public, mitigation banks, and in-
lieu fee programs. One commenter said that if the threshold for
requiring stream compensatory mitigation is going to be changed from
linear feet to acres, the acreage should include all of the affected
area on the valley bottom, not just the area between ordinary high
water marks of a river or stream.
The establishment of the \3/100\-acre threshold for stream
compensatory mitigation for NWP activities is an administrative
decision to facilitate consistent implementation across districts. It
is intended to be a conservative threshold based on the complexities of
riverine systems, the substantial variation in riverine systems across
the country, and the subjectivity inherent in the threshold for the
NWPs (i.e., no more than minimal individual and cumulative adverse
environmental effects). The use of acres to quantify stream
compensatory mitigation is consistent with the Corps' compensatory
mitigation regulations at 33 CFR 332.8(o)(1), which does not mandate
the use of a particular metric for quantifying stream compensatory
mitigation credits. It would be inappropriate to use the area of a
valley bottom, since the Corps only has jurisdiction over certain
categories of waters and wetlands, and valley
[[Page 2833]]
bottoms may consist of a substantial proportion of upland area or other
features that are outside of the Corps' jurisdiction.
Several commenters said the change to an area-based approach would
not provide accounting consistency and would result in dual accounting
systems for credits and debits generated under both linear feet and
acreage-based scenarios and it would create inconsistencies, and would
create confusion over how to handle sold versus proposed credits. One
commenter expressed concern that ecological values of mitigation
credits would not carry over in the conversion from linear feet to
acres, creating the potential for activities to result in more than
minimal individual and cumulative adverse environmental effects.
There is no requirement in the Corps' regulations to quantify
stream compensatory mitigation credits in linear feet. Compensatory
mitigation credits, including stream credits, can be quantified in
acres, linear feet, functional assessment units, or other suitable
metrics of particular resource types (33 CFR 332.8(o)(1)). This final
rule does not affect prior credit transactions for previously
authorized NWP activities where the permittee secured stream
compensatory mitigation credits from mitigation bank or in-lieu fee
program sponsors. This final rule only applies to activities authorized
by these NWP after they go into effect. The Corps acknowledges that a
period of adjustment will be required, and that different agencies may
require the use of different metrics to quantify losses of stream bed
and stream compensatory mitigation credits. The ecological values of
mitigation credits from the accrual or attainment of aquatic functions
at a compensatory mitigation site (see the definition of ``credit'' at
33 CFR 332.2). Quantifying stream mitigation credits in acres or linear
feet is a surrogate for the increases in stream functions expected to
result from a stream compensatory mitigation project, when there is no
method available to assess the specific functional gains through a
rapid ecological assessment method or other method.
The amount of compensatory mitigation required for an NWP activity
has to be sufficient to replace lost aquatic resource functions (see 33
CFR 332.3(f)(1)), and the mitigation provider can use his or her
judgment or the approved mitigation plans to determine how many stream
credits quantified in linear feet are needed to offset a particular
acreage of stream bed that is filled or excavated as a result of an NWP
activity. It is important to note that the mitigation industry provides
a service to permittees, as an option to fulfill the compensatory
mitigation requirements in NWP authorization and other forms of DA
authorizations. The Corps is making these changes for administrative
efficiency, to provide NWP authorization for more activities that
result in no more than minimal individual and cumulative adverse
effects. The 300 linear foot limit for losses of stream bed in the 2017
NWPs and prior NWPs required the Corps to process individual permits
for activities that likely would have otherwise qualified for NWP
authorization. In the 2007 NWPs, general condition 23 was modified to
state that district engineers could require stream compensatory
mitigation for losses of stream bed, but there was no acreage threshold
as there was for wetland losses. In paragraph (d) of this general
condition, the Corps has established a\ 3/100\-acre threshold for
stream compensatory mitigation. District engineers can require
compensatory mitigation for losses of less than \3/100\-acre of stream
bed, and they can require compensatory mitigation for losses of up to
\1/2\-acre of stream bed.
One commenter said mitigation banks and in-lieu fee programs would
be negatively affected because less compensatory mitigation would be
required for the loss of stream beds. A few commenters said they have
reservations about the implementation of a compensatory mitigation
threshold for losses of stream bed and that there may not be bank or
in-lieu fee program credits available.
The removal of the 300 linear foot limit for losses of stream bed
from NWPs 21, 29, 39, 40, 42, 43, 44, 50, 51, and 52 and the changes to
this general condition will not result in less compensatory mitigation
being required for losses of stream bed authorized by NWPs. By
providing equivalent quantitative limits for all non-tidal
jurisdictional waters and wetlands in these 10 NWPs (i.e., the \1/2\-
acre limit), there will likely be more NWP activities for which
district engineers require compensatory mitigation. As discussed above,
the Corps has changed the threshold from \1/10\-acre to \3/100\-acre to
require stream compensatory mitigation that is more aligned with
current practices and the recommendations of many commenters. The
existing stream credits can be used for NWP activities, even though the
authorized impacts will be quantified in acres.
Several commenters supported the flexibility of the district
engineer to allow other forms of mitigation as determined appropriate
and to waive compensatory mitigation requirements after an activity
specific determination that other forms of mitigation would be
environmentally preferable. Several commenters said that increased
impacts and allowing the district engineer to waive compensatory
mitigation requirements would be counterproductive to the success of
salmon recovery efforts, and therefore would not be protective of
tribal treaty rights. Several commenters said the district engineer
should be able to consider other site-specific activities required by
other regulatory programs, such as mine site reclamation to considered
as mitigation for activities affecting stream beds. One commenter
stated that requiring a compensatory mitigation decision by the
district engineer could delay issuance of a permit and to modify
paragraph (d) to allow the district engineer or designee to waive the
compensatory mitigation requirement. One commenter expressed concern
that allowing the district engineer to waive compensatory mitigation
requirements could allow for up to \1/2\-acre of stream bed loss which
would result in adverse environmental impacts.
The removal of the 300 linear foot limit from the NWPs (while
retaining the \1/2\-acre limit, PCN process, and other tools to ensure
no more than minimal adverse environmental effects) and the changes to
general condition 23 will allow district engineers to authorize certain
activities by NWP and require compensatory mitigation when necessary.
It will provide more flexibility in the NWP and allow district
engineers to devote more staff and other resources to proposed
activities that have the potential for more substantial adverse
environmental effects. These changes will not impair salmon recovery
efforts, and for those proposed NWP activities that the district
engineer determines ``may affect'' listed salmon species, additional
protection to those listed species will be provided through the ESA
section 7 process.
The flexibility in general condition 23 allows district engineers
to consider mitigation and other site-specific activities required by
other agencies, such as mine reclamation, when determining whether to
require compensatory mitigation for NWP activities. District engineers
are required to make compensatory mitigation decisions within the 45-
day review period for NWP PCNs. The district engineer has the decision-
making authority for whether compensatory mitigation is required for an
NWP activity.
[[Page 2834]]
One commenter said the Corps should develop clear expectations and
performance standards for the types of other mitigation that could be
utilized to compensate for stream bed losses. One commenter suggested
modifying paragraph (d) to list acceptable alternatives to compensatory
mitigation. One commenter expressed support for compensatory mitigation
requirements could be fulfilled through restoration or enhancement of
riparian areas next to streams. Several commenters said that riparian
restoration or enhancement results in out-of-kind mitigation since they
do not always replace lost stream functions. One commenter suggested
the proposed paragraph (d) be modified to state that riparian
restoration or enhancement may only satisfy compensatory mitigation
requirements when other in-kind mitigation options are unavailable or
are not practicable.
Ecological performance standards for stream compensatory mitigation
projects are determined by district engineers when they review and
approve mitigation plans. Permit applicants may propose potential
alternatives to compensatory to district engineers, who will determine
whether that alternative mitigation is appropriate and likely to be
effective in reducing adverse environmental effects so that it is not
necessary to require compensatory mitigation. While the restoration or
enhancement of riparian areas might not replace all stream functions,
they can help improve some stream functions and help reduce nutrient
and pollutant loads to streams. District engineers will determine on a
case-by-case basis whether the restoration or enhancement of riparian
areas is appropriate and practicable compensatory mitigation for an NWP
activity.
One commenter said that the general condition should be modified to
require the applicant to provide project specifications addressing the
Natural Stream Channel Design Techniques and Review Checklist,
developed by the U.S. EPA and U.S. FWS. One commenter said there
currently are no national or regional tools developed by the Corps to
guide compensatory mitigation for stream bed losses. One commenter
stated the Corps and U.S. EPA are currently collaborating on a peer-
reviewed study analyzing the environmental and policy consequences of
stream restoration metrics. This commenter recommended not modifying
the NWPs until they are scheduled to expire in 2022 to allow for the
results of the study to be completed and the results to be considered.
One commenter said general condition 23 should be incorporated into
every applicable NWP rather than referring to the loss of 300 linear
feet in each NWP.
District engineers evaluate stream compensatory mitigation
proposals and should be provided the flexibility to consider a variety
of potential stream restoration or rehabilitation approaches. This
includes river and stream restoration approaches, such as dam removals,
culvert replacements, and other process-based methods that may be more
ecologically effective than natural channel design in improving stream
functions (e.g., Palmer et al. 2014). The Corps is removing the 300
linear foot limit for losses of stream bed from 10 NWPs and modifying
general condition 23 for more efficient administration of the NWP
program. The study on stream metrics may have some utility in future
rulemakings and the development of guidance, but it is not necessary to
delay this rulemaking to wait for that study to be completed. General
condition 23 applies to all NWPs.
Several commenters supported the proposed changes to paragraph (e).
Several commenters said that paragraph (e) of general condition 23
should be modified to eliminate the district engineer's ability to
allow riparian area compensatory mitigation for wetland losses. One
commenter suggested modifying paragraph (e) to allow the planting of
adapted seed mixes that may contain non-native species and to allow for
the replacement of existing vegetation when restoring riparian areas.
One commenter said the proposed condition should be modified to state
that use of native vegetation is preferred, rather than required, and
to allow for consideration of regionally appropriate vegetation. A few
commenters expressed opposition to the proposed changes the changes to
paragraph (e) and expressed concerns that allowing non-native species
would result in negative environmental effects. One commenter said they
were concerned that allowing non-native species in the restored areas
could negate the prevention, control, and management of non-native
species performed by other government agencies, non-government
organizations, and citizens and could introduce a source for spread
among those activities.
The restoration and enhancement of riparian areas may be used to
offset wetland losses as another form of mitigation that could be more
environmentally appropriate, since riparian areas perform a number of
functions that are also performed by wetlands (NRC 1995, NRC 2002).
There may be a number of seed mixes that are acceptable for
revegetating riparian areas. Paragraph (e) contains flexibility because
it states that native species should be planted; it does not require
native species to be planted. As discussed in the proposed rule, non-
native species can have positive, negative, or neutral effects on
ecosystems and the functions they perform. Compensatory mitigation
requirements, including long-term management activities, must be
practicable (see 33 CFR 332.3(a)(1)). For a particular compensatory
mitigation site, the district engineer may determine that the
management of invasive or non-native species is not practicable cause
of site or watershed conditions, the degree to which the invasive or
non-native species is established in the region, and other factors. If
other government agencies and non-governmental organizations want to
undertake efforts to control invasive or non-native species, they can
do that under their authorities or mission statements.
Several commenters said there is no support for allowing narrow
riparian areas of 25-50 feet wide on each side of the stream that would
support habitat needed by federally threatened or endangered salmon.
Buffers of 100 feet or more are needed. One commenter said that
riparian area restoration and enhancement requirements (e.g. minimum
riparian width, historical and existing site conditions) should be
addressed regionally rather than included in paragraph (e). One
commenter said that restoring or enhancing riparian areas does not
achieve no-net-loss of the stream bed.
The recommended riparian area width of 25-50 feet was established
in the NWP program in 2000 (65 FR 12833) because riparian areas of that
width can provide important aquatic habitat functions and water quality
benefits. The establishment of wider riparian areas for listed species
be more appropriately addressed through the ESA section 7 consultation
process. Division and district engineers can establish regional
requirements for riparian areas. The purpose of restoring and enhancing
riparian areas is to help improve stream functions and water quality.
The improved functions are expected to occur in nearby stream bed and
in downstream waters.
One commenter recommended modifying paragraph (f)(4) of this
general condition to state that if permittee-responsible mitigation is
the proposed compensatory mitigation option, and the proposed
compensatory mitigation site is located on land in which another
federal agency holds an easement, the district engineer will
[[Page 2835]]
coordinate with that federal agency to determine if proposed
compensatory mitigation project is compatible with the terms of the
easement. The Corps added the suggested text to paragraph (f)(4) of
general condition 23.
This general condition is adopted with the modifications discussed
above.
GC 24. Safety of Impoundment Structures. The Corps did not propose
any changes to this general condition. One commenter recommended adding
``federal'' to this general condition because some federal agencies may
have established federal dam safety criteria. The Corps added
``federal'' to the text of this general condition so that district
engineers can require non-federal applicants to demonstrate that the
structures comply with established federal dam safety criteria.
This general condition is adopted as with the modification
discussed above.
GC 25. Water Quality. The Corps proposed to modify this general
condition to articulate that if the state, authorized tribe, or EPA
(i.e., the certifying authority under section 401 of the Clean Water
Act) issued a water quality certification (WQC) for the issuance of an
NWP, and the permittee cannot comply with all of the conditions in that
water quality certification, he or she must submit a certification
request to the certifying authority that satisfies the requirements of
40 CFR 121.5(b) for a water quality certification or waiver for the
activity involving a specific discharge to be authorized by the NWP.
One commenter expressed general support for the proposed changes to
general condition 25. Several commenters supported the proposed changes
clarifying that applicants need to request certification from the
certifying authority for specific discharges when he or she cannot
comply with all of the conditions in the WQC for the NWP. One commenter
said that general condition 25 should be clarified to state that WQCs
must be consistent with 33 CFR 325.4 and 40 CFR 121.7(d), and that any
WQC condition not within the established scope of the certification,
may not be included as a regional condition.
The proposed changes have been incorporated into this general
condition. The Corps has added text to this general condition to state
that if the certifying authority issues a water quality certification
for the proposed discharge authorized by a specific NWP activity, the
permittee must submit a copy of the certification to the district
engineer. Furthermore, the general condition states that if
certification is required for a specific discharge, the discharge is
not authorized by an NWP until the district engineer has notified the
permittee that the water quality certification requirement has been
satisfied.
When water quality certification is required for a specific
discharge authorized by an NWP, and the Corps has completed its review
of the PCN and has determined that the activity is authorized by an NWP
as long as water quality certification is issued or waived for that
discharge, the district engineer will send a provisional notification
to the permittee. The provisional notification will inform the project
proponent that the activity will be authorized by an NWP once water
quality certification for the proposed discharge is obtained or waived.
If water quality certification is issued for the proposed discharge,
the district engineer will conduct coordination that may be required
under Section 401(a)(2) of the Clean Water Act. After that process, the
district engineer will issue the NWP verification letter with the water
quality certification. The district engineer may add conditions to the
NWP authorization to ensure the authorized activity results in no more
than minimal individual and cumulative adverse environmental effects.
The district engineer will also add to the NWP authorization conditions
in the water quality certification that are not waived pursuant to 40
CFR 121.9(b).
The Corps divided the text of this general condition into three
paragraphs to make the general condition easier to read. This general
condition is adopted with the modifications discussed above.
GC 26. Coastal Zone Management. The Corps proposed to modify this
general condition to say that if the state issued a general Coastal
Zone Management Act (CZMA) consistency concurrence for the NWP, and the
permittee cannot comply with all conditions of that general
concurrence, then he or she must obtain an individual CZMA consistency
concurrence or presumption of concurrence from the state in order for
the activity to be authorized by an NWP.
Several commenters expressed support for the change, stating that
it provided clarification of the consistency concurrence process and
additional flexibility. The commenters further noted that the proposed
language makes it clear that the permittee is expected to fully comply
with all the conditions of the general concurrence or seek an
individual CZMA consistency concurrence or presumption of concurrence
from the state coastal program.
To qualify for NWP authorization, the proposed activity must comply
with all of the NWP's terms and conditions (see 33 CFR 330.1(c)). The
Corps will consider unauthorized any activity requiring Corps
authorization if that activity is under construction or completed and
does not comply with all of the terms and conditions of an NWP. This
includes any conditions added to the NWP authorization through a
categorical or individual CZMA consistency concurrence. If the
applicant cannot comply with all of the conditions in the general CZMA
consistency concurrence, then in order to comply with the requirements
of the CZMA, she or he would need to apply to the state for an
individual CZMA consistency concurrence, or obtain a presumption of
concurrence. The inability to comply with all conditions of a general
CZMA consistency concurrence does not preclude the use of the NWP to
authorize the permitted activities; such circumstances would be
considered a denial without prejudice until the project proponent
obtains an individual CZMA consistency concurrence or a presumption of
concurrence.
When CZMA consistency concurrence is required for a specific
activity authorized by an NWP, and the Corps has completed its review
of the PCN and has determined that the activity is authorized by an NWP
as long as CZMA consistency concurrence is issued or a presumption of
concurrence occurs for the activity, the district engineer will send a
provisional notification to the permittee. The provisional notification
will inform the project proponent that the activity will be authorized
by an NWP once CZMA consistency concurrence for the proposed activity
is obtained or a presumption of concurrence occurs. The district
engineer may add conditions to the NWP authorization to ensure the
authorized activity results in no more than minimal individual and
cumulative adverse environmental effects.
The general condition is adopted as proposed.
GC 27. Regional and Case-By-Case Conditions. The Corps did not
propose any changes to this general condition. No comments were
received. The general condition is adopted as proposed.
GC 28. Use of Multiple Nationwide Permits. The Corps proposed
changes to this general condition to address the use of more than one
NWP to authorize a single and complete project, when two of those NWPs
have different acreage limits. The proposed changes were
[[Page 2836]]
intended to ensure that use of an NWP with a higher acreage limit could
not circumvent the lower acreage limit for another NWP, when the two
NWPs are combined to authorize a single and complete project.
A few commenters expressed support for the change and said that it
clarified language regarding the use of multiple NWPs for a single and
complete project. Several commenters recommended making no changes to
this general condition, and retaining the general condition language
from the 2017 NWPs. One commenter suggested that the NWP numbers used
in the example in the text of the general condition should match the
NWP numbers used in the example in the preamble to the proposed rule,
specifically by using NWP 39 rather than NWP 29. One commenter said
that no more than two NWPs should be used to authorize a single and
complete project. One commenter stated that the use of multiple NWPs to
authorize a single and complete project should not cumulatively exceed
the threshold of the highest limit.
In the example in the text of this general condition, the Corps has
replaced NWP 29 with 39 to make the example clearer. Nationwide permit
29 has a subdivision provision that adds an additional layer of
complexity, so it would be simpler to use NWP 39 in the example since
that NWP has no subdivision provision. There may circumstances in which
more than three NWPs may be appropriate for authorizing a single and
complete project. One commenter stated that the use of multiple NWPs to
authorize a single and complete project should not cumulatively exceed
the threshold of the highest limit. The general condition does limit
the acreage loss of waters of the United States to the highest
specified acreage limit, but it does not allow the acreage limit of an
NWP with a lower acreage limit to be exceeded.
One commenter stated that the proposed language would limit use of
NWPs with no acreage limit, such as NWP 3 in combination with other
NWPs, where it may be desirable to allow additional work beyond a
specified acreage to occur as it would promote re-use and
rehabilitation of existing structures rather than construction of new
structures. One commenter recommended that the Corps provide
clarification regarding how temporary and cumulative impacts would be
addressed when more than one NWP is used to authorize a single and
complete project.
The text in paragraph (a) of this general condition will limit the
use of NWPs with no acreage limits, as it has since this text was
incorporated into this general condition in 2000 (47 FR 12896). The
general condition applies to losses of waters of the United States, as
that term is defined in Section F of the NWPs. It does not include
temporary impacts. Cumulative impacts are addressed separately during
the district engineer's review of the PCN, in accordance with paragraph
2 of Section D, District Engineer's Decision.
Several commenters stated that the Corps must prohibit the use of
multiple NWPs and NWPs with other general or individual permits as the
Corps is not assessing the cumulative impacts. A few commenters stated
that the proposed change may result in a greater loss of waters, and
expressed concern that allowing two NWPs with different specified
acreage limits to be used would result in larger impacts than allowed
by each individual NWP. A few commenters said that allowing the use of
more than one NWP to authorize a single and complete project will
result in more than minimal individual and cumulative adverse
environmental effects. One commenter suggested that the Corps eliminate
the use of multiple NWPs to authorize individual segments of linear
projects.
The Corps considers cumulative impacts when it evaluates PCNs for
proposed NWP activities (see paragraph 2 of Section D, District
Engineer's Decision). General condition 28 does not address the use of
NWPs with individual permits; it only addresses the use of multiple
NWPs to authorize a single and complete project. The use of NWPs with
individual permits is addressed in the Corps' NWP regulations at 33 CFR
330.6(d). The modification of this general condition is specifically
intended to prohibit the circumvention of the specified acreage limits
of the NWPs, so that the loss of waters of the United States under a
particular NWP is not exceeded.
Not allowing any deviation from the specified acreage limits of the
NWPs used to authorize a single and complete project will help ensure
that authorized activities will result in no more than minimal
individual and cumulative adverse environmental effects. This general
condition does not apply to the long-standing practice of allowing each
separate and distant crossing of waters of the United States for a
linear project to be considered a separate NWP authorization. This
general condition does apply to circumstances where a linear project
may involve two separate utility lines (e.g., an electric utility line
authorized by NWP 57 and a water line authorized NWP 58) both cross a
waterbody. In this situation, the \1/2\-acre limit would apply to the
cumulative loss of waters of the United States caused by the electric
line and water line crossing of that waterbody.
The general condition is adopted with the modifications discussed
above.
GC 29. Transfer of Nationwide Permit Verifications. The Corps did
not propose any changes to this general condition. No comments were
received. The general condition is adopted as proposed.
GC 30. Compliance Certification. The Corps did not propose any
changes to this NWP. No comments were received. The general condition
is adopted as proposed.
GC 31. Activities Affecting Structures or Works Built by the United
States. The Corps proposed to modify this general condition to be
consistent with the current Engineer Circular (EC) for processing
requests to alter Corps Civil Works Projects pursuant to 33 U.S.C. 408
(EC 1165-2-220, issued on September 10, 2018). Under the current EC,
Corps districts are required to conduct section 10 and section 404
permit evaluations and requests for 408 permissions in a coordinated
and concurrent manner.
One commenter supported the proposed changes to this general
condition. One commenter stated that a PCN should not be required for a
Section 408 review or permission if the underlying NWP activity does
not otherwise require a PCN. One commenter said that the proposed text
raises concerns about timely processing of NWPs.
Pre-construction notifications are required for proposed NWP
activities that also require Section 408 permissions so that the
appropriate coordination can occur between district staff involved in
the NWP authorization and Section 408 permission processes. The Corps
acknowledges that it may take longer for NWP verification letters to be
issued by the district engineer, because the NWP verification cannot be
issued before the Section 408 permission process is completed.
The general condition is adopted as proposed.
GC 32. Pre-Construction Notification. The Corps proposed several
modifications to this general condition to provide consistency with
proposed changes to the NWPs and to clarify pre-construction
notification requirements. The Corps proposed to change paragraph
(a)(2) of this general condition by removing the following sentence:
``Also, work cannot begin under NWPs 21, 49, or 50 until the permittee
has received written approval
[[Page 2837]]
from the Corps.'' This proposed change will conform to one of the
changes we are proposing for these three NWPs, which is to remove the
term requiring the permittee to obtain a written verification from the
district engineer before commencing the regulated activities in waters
of the United States. As discussed above, the Corps proposed to make
NWPs 21, 49, and 50 consistent with the other NWPs that require pre-
construction notification, where the project proponent can proceed with
the authorized work if the district engineer does not respond to the
PCN within 45 days (see 33 CFR 330.1(e)(1)).
Many commenters expressed concern with the 45-day clock and the
default authorization of PCNs and questioned whether this was a
sufficient review period. Many commenters stated that the Corps should
hold districts accountable regarding when the 45-day PCN review period
starts and limit information requests to a single request. These
commenters further stated that some Corps districts make numerous
information requests to reset the 45-day review period or request
additional information not listed in the text of the general condition.
One commenter suggested that the Corps provide more direction/guidance
to districts on the ability to use sketches (rather than engineered
drawings). A few commenters said that no additional information
requirements should be added to the PCN process that would further
complicate or burden the process. One commenter recommended that
district engineer use their discretionary authority to expedite certain
time-sensitive maintenance and inspection projects associated with key
energy infrastructure projects.
Forty-five days is sufficient time for district engineers to review
PCNs and determine whether proposed activities qualify for NWP
authorization or whether discretionary authority should be exercised to
require individual permits. Exceptions to the 45-day review period when
district engineers have to complete ESA section 7 consultation, NHPH
section 106 consultations, or other required consultations. District
engineers are supposed to make only one request for additional
information to make PCNs complete. District engineers can make
additional requests only when the project proponent has not submitted
the requested information to the district engineer. A complete PCN only
requires the information listed in general condition 32, plus the text
of the NWP itself if the ``Notification'' provision includes additional
information requirements. The sketches submitted with a PCN have to be
sufficiently detailed to help a district engineer understand the
proposed activity, but it does not have to be an engineering drawing or
a comparably detailed drawing. The Corps has not added any more
information requirements beyond what was proposed in the 2020 Proposal.
The Corps does not agree that general condition 32 should be modified
to state that a district engineer has discretionary authority to
expedite certain time-sensitive maintenance and inspection activities.
District engineers already have the discretion to manage their
workload.
The Corps also proposed to modify paragraph (b)(4) of this general
condition by dividing it into subparagraphs to clarify different
requirements of a complete PCN: The description of the proposed NWP and
associated information (subparagraph (b)(4)(i)); the quantities of
anticipated losses of waters, wetlands, and other special aquatic sites
for linear projects (subparagraph (b)(4)(ii)); and the inclusion of
sketches with the PCN (subparagraph (b)(4)(iii)). In subparagraph
(b)(4)(i), the Corps also proposed to add ``(including the same NWP for
activities that do not require PCNs)'' after ``any other NWP(s)'' to
clarify that the PCN must identify non-PCN NWPs that are used to
authorize any part of the proposed project or related activity,
including separate and distant crossings of waters and wetlands for
linear projects. In subparagraph (b)(4)(ii), the Corps proposed to
clarify the information requirements for linear projects, and state
that these information requirements do not trigger a PCN requirement
for those crossings authorized by an NWP that do not require PCNs. The
Corps also proposed to modify this subparagraph to state that this
information will be used by the district engineer to evaluate the
cumulative adverse environmental effects of the proposed linear
project.
A few commenters expressed support for the proposed changes,
particularly the clarification that a PCN must identify non-PCN NWPs
used to authorize other aspects of projects, including linear projects.
The Corps has incorporated the proposed changes into paragraph (b)(4).
In the first sentence of paragraph (b)(5), the Corps proposed to
remove the phrase ``and perennial, intermittent, and ephemeral
streams,'' and replace it with ``streams.'' If there are streams on the
project site, then the PCN must include a delineation of those streams.
In addition, the Corps proposed to modify paragraph (b)(5) to be
consistent with its proposal to remove the 300 linear foot limit for
losses of stream bed in NWPs 21, 29, 39, 40, 42, 43, 44, 50, 51, and
52, and rely on the \1/2\-acre limit, PCN review process, and the
ability of division and district engineers, based on regional or local
conditions, to modify, suspend, or revoke NWP authorizations on a
regional or case-by-case basis, respectively, to comply with the
requirement that NWPs may only authorize those activities that have no
more than minimal individual and cumulative adverse environmental
effects. The delineation of streams on the project site will be used to
calculate the area of stream bed is proposed to be filled or excavated
and thus results in a loss of stream bed. The area of jurisdictional
stream bed filled or excavated would be applied to the \1/2\-acre limit
for these NWPs, to determine whether the loss of stream bed plus the
losses of any other non-tidal jurisdictional waters and wetlands
exceeds the \1/2\-acre limit.
A few commenters stated that the Corps should add the word
``jurisdictional'' to ``streams'' in paragraph (b)(5). One commenter
recommended that the Corps clarify that paragraph (b)(5) only applies
to jurisdictional waters. One commenter stated that the use of the word
``ephemeral'' in paragraph (b)(5) is inconsistent with the Navigable
Waters Protection Rule and recommended omitting the term from the
general condition. One commenter opposed the addition of ``streams'' in
paragraph (b)(6) and requiring PCNs for stream losses in excess of \1/
10\-acre, since the removal of the 300-foot limit only applies to 10
NWPs.
The Corps declines to add the word ``jurisdictional'' to modify the
word ``stream'' or other types of waters listed in paragraph (b)(5)
because an approved jurisdictional determination is not required for an
NWP PCN. If the project proponent did not obtain an approved
jurisdictional determination for the project site prior to submitting
the PCN, for the purposes of evaluating the PCN the district engineer
will presume the wetlands, streams, and other waters on the project
site are subject to Clean Water Act jurisdiction. The Corps has removed
the word ``ephemeral'' from paragraph (b)(5). Paragraph (b)(6) does not
impose any additional PCN requirements for losses of stream bed. The
first sentence of paragraph (b)(6) has been revised as follows to
incorporate the mitigation thresholds in general condition 23: ``If the
proposed activity will result in the loss of greater than \1/10\-acre
of wetlands or \3/100\-acre of stream bed and a PCN is required, the
prospective permittee must submit a
[[Page 2838]]
statement describing how the mitigation requirement will be satisfied,
or explaining why the adverse environmental effects are no more than
minimal and why compensatory mitigation should not be required.''
The Corps proposed to modify paragraph (c) to state that the PCN
should be submitted using Form ENG 6082 that was approved earlier this
year. Form ENG 6082 should be used instead of ENG 4345, which is the
standard individual permit application form. Block 18 of Form ENG 6082
has a space for the project proponent to identify the specific NWP(s)
she or he wants to use to authorize the proposed activity. Therefore,
the Corps proposed to remove the text of paragraph (c) that stated that
a completed ENG 4345 must clearly indicated that it is an NWP PCN and
must include all of the information required by subparagraphs (b)(1)
through (10) of this general condition.
One commenter stated that paragraph (c), which references the use
of ENG 6082, should be altered to include allowance for states that
have a joint application process. The ENG Form 6082 has been approved
for purposes of the Paperwork Reduction Act, but joint state-federal
forms have not been approved. Therefore, the Corps declines to make
this suggested change.
Because of the proposal to remove the 300 linear foot limit for
losses of stream bed in NWPs 21, 29, 39, 40, 42, 43, 44, 50, 51, and
52, as well as the associated waiver provision for losses of
intermittent and ephemeral stream bed, the Corps proposed to modify
paragraph (d)(2) of the agency coordination provisions of this general
condition. The Corps proposed to remove the requirement for agency
coordination for NWP 21, 29, 39, 40, 42, 43, 44, 50, 51, and 52
activities that require pre-construction notification and will result
in the loss of greater than 300 linear feet of stream bed.
Several commenters objected to the removal of the agency
coordination process with the removal of the 300 linear foot limit for
loss of stream bed. One commenter stated that removal of the agency
coordination process resulting from the removal of PCN requirements may
lead to the Corps being the only entity involved in the review of
potential source water (i.e. drinking water) impacts. One commenter
stated that the PCN requirement is a benefit for state agency
coordination, which assists the applicant and regulatory agencies in
permit streamlining.
The Corps has removed the agency coordination provisions for
waivers for losses of greater than 300 linear feet of intermittent or
ephemeral stream bed for activities authorized by NWPs 21, 29, 39, 40,
42, 43, 44, 50, 51, and 52. The NWPs do not require district engineers
to coordinate proposed activities that may affect source waters or
drinking water supplies. Pre-construction notifications are required
for certain NWP activities, and coordination with state agencies is
only required for specific activities identified in paragraph (d) of
this general condition.
This general condition is adopted with the modifications discussed
above.
I. Discussion of Proposed Modifications to Section D, District
Engineer's Decision
In paragraph 1 of Section D, the Corps proposed to remove
provisions that refer to potential waivers of the 300 linear foot limit
for losses of stream bed authorized by NWPs 21, 29, 39, 40, 42, 43, 44,
50, 51, and 52. The Corps proposed this change to be consistent with
our proposal to remove the 300 linear foot limit and the waiver
provision from those NWPs. In the second sentence of paragraph 4, the
Corps proposed to remove ``or to evaluate PCNs for activities
authorized by NWPs 21, 49, and 50'' because we are proposing to remove
the requirement that permittees obtain written verification from the
district engineer before these activities are authorized. Pre-
construction notifications for activities authorized by NWPs 21 and 50
will be subject to the same timeframes as other NWP activities that
require PCNs, because the Corps removed the provision from these NWPs
that required the permittee to obtain written verification from the
Corps before commencing the authorized activity. This includes the
ability for the permittee to presume that her or his project qualifies
for the NWP unless she or he is otherwise notified by the district
engineer within a 45-day period (see 33 CFR 330.1(e)(1)), or Endangered
Species Act Section 7 consultation and/or National Historic
Preservation Act Section 106 consultation needs to be completed for
non-federal permittees to comply with the requirements of general
conditions 18 and 20.
One commenter said the Corps should only use functional assessments
that have been developed, peer reviewed, and subject to public and
stakeholder comment at the regional level, and that the Corps not
unilaterally revise the tools or substitute alternative methodologies
only when the Corps prefers. The Corps determines which functional
assessments are appropriate for use in evaluating NWP PCNs and other
applications for DA authorization. The Corps does not require
functional assessments to be peer reviewed, but acknowledges that peer
review can help improve functional assessments to better assess aquatic
resource functions. The Corps has modified the first sentence of
paragraph 3 of this section to be consistent with the wetland and
stream mitigation thresholds in general condition 23. That sentence has
been changed to read: ``If the proposed activity requires a PCN and
will result in the loss of greater than \1/10\-acre of wetlands or \3/
100\-acre of stream bed, the prospective permittee should submit a
mitigation proposal with the PCN.''
J. Discussion of Proposed Modifications to Section F, Definitions
In the 2020 Proposal, the Corps proposed changes to some of the NWP
definitions and the Corps proposed to remove some definitions. Several
commenters stated that the definitions in Section F should match the
definitions used in the Navigable Waters Protection Rule and in other
regulations. A few commenters suggested retaining the definitions for
intermittent stream and ephemeral stream. One commenter suggested
repeating all ``geographic definitions'' in the NWP definitions. One
commenter requested definitions for levee, berm and dike. One commenter
asked that the Corps differentiate between ``top of bank,'' ``ordinary
high water mark'' and ``bankfull elevation.'' One commenter expressed
concern with the proposed removal of definitions for ``protected tribal
resources,'' ``ephemeral streams'' and ``intermittent streams.''
As discussed in the proposed rule, the Corps proposed to modify the
definitions of ``ordinary high water mark'' and ``perennial stream'' to
be consistent with the Navigable Waters Protection Rule at 33 CFR
328.3(c)(7) and 33 CFR 328.3(c)(8). The Corps is removing the
definitions of intermittent stream and ephemeral stream because they
are no longer used in the text of the NWPs. The Corps does not believe
it is necessary to copy the entire definition of ``waters of the United
States'' into the NWPs because that definition is available at 33 CFR
328.3. The Corps declines to add definitions of the terms ``levee,''
``berm,'' ``dike,'' and ``top of bank.'' The Corps does not see a need
to differentiate or define the terms ``top of bank'' or ``bankfull
elevation'' because those terms are not used in the NWPs. The
definition of ``protected tribal resources'' has been removed because
that phrase is no longer in the text of general condition 17, tribal
rights. The term ``protected tribal resources'' continues to be applied
[[Page 2839]]
through the Corps' implementation of the 1998 Department of Defense
American Indian and Alaska Native Policy.
One commenter stated that unless a definition of ``water of the
United States'' is included or referenced all waterbodies should be
defined within the NWPs to avoid confusion. One commenter requested a
definition of ``adjacent wetlands'' that is consistent across all
regulations. One commenter suggested adding a definition of ``oil and
gas pipeline.'' One commenter supported retention of the definitions
for ``single and complete linear project,'' ``single and complete non-
linear project'' and ``independent utility.'' One commenter suggested
adding a definition of ``stream'' to differentiate between linear
wetlands and streams for compensatory mitigation purposes.
The phrase ``waters of the United States'' is defined at 33 CFR
part 328.3. The term ``adjacent wetlands'' is defined at 33 CFR
328.3(c)(1)). The term ``oil or natural gas pipeline'' is defined in
the text of NWP 12. The Corps declines to add a definition of
``stream'' because the NWPs include a definition of ``stream bed.'
Best management practices (BMPs). The Corps did not propose any
changes to this definition. The Corps did not receive any comments on
the proposed definition. The definition is adopted as proposed.
Compensatory mitigation. The Corps did not propose any changes to
this definition. The Corps did not receive any comments. The definition
is adopted as proposed.
Currently serviceable. The Corps did not propose any changes to
this definition. One commenter stated that the proposed definition
includes the unclear phrase ``some maintenance'' and requested
clarification. The Corps declines to clarify the phrase ``some
maintenance'' because it is subject to application on a case-by-case
basis.
The definition is adopted as proposed.
Direct effects. The Corps did not propose any changes to this
definition and did not receive any comments. The definition is adopted
as proposed.
Discharge. The Corps did not propose any changes to this
definition. One commenter said that the proposed definition includes
the word being defined in its definition and suggested edit of the
definition replacing the word discharge in the definition with
``addition'', ``release'', or ``placement.'' The Corps declines to make
the suggested changes because the Corps regulates discharges of dredged
or fill material and those terms are more comprehensively defined in 33
CFR 323.2.
The definition is adopted as proposed.
Ecological reference. The Corps did not propose any changes to this
definition. The Corps We did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Enhancement. The Corps did not propose any changes to this
definition. The Corps We did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Ephemeral stream. The Corps proposed to remove the definition of
``ephemeral stream'' in conjunction with the proposal to remove the 300
linear foot limit for losses of stream bed and the ability of district
engineers to waive that 300 linear foot limit for losses of ephemeral
stream bed on a case-by-case basis. It should also be noted that
ephemeral features, including ephemeral streams, are excluded from the
definition of ``waters of the United States'' at 33 CFR 328.3(b)(3).
Section 328.3 of the Corps' regulations defines ``waters of the United
States'' for the purposes of the Clean Water Act.
A few commenters stated that the definition of ``ephemeral stream''
should be retained given the importance of stream categorization in
jurisdiction and thus whether an NWP is necessary. One commenter stated
that the definition should be retained to differentiate ephemeral
streams from intermittent and perennial streams. One commenter
supported the removal of the definition given proposed elimination of
the 300 linear foot limit from the NWPs and the exclusion of ephemeral
streams from jurisdiction under the Navigable Waters Protection Rule.
One commenter expressed opposition to the definition's removal based on
opposition to removal of the 300 linear foot limit from the NWPs. One
commenter stated that the term should be retained because a cumulative
impacts analysis may include a determination of flow through ephemeral
and intermittent streams.
The Corps is removing this definition as proposed because, in
accordance with the Navigable Waters Protection Rule, ephemeral
features, including ephemeral streams, are categorically excluded from
the definition of ``waters of the United States'' under the Clean Water
Act (see 33 CFR 328.3(b)(3)).
Establishment (creation). The Corps did not propose any changes to
this definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
High Tide Line. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Historic property. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Independent utility. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Indirect effects. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Intermittent stream. The Corps proposed to remove the definition of
``intermittent stream,'' in conjunction with the proposal to remove the
300 linear foot limit for losses of stream bed which obviated the need
to reference a waiver for losses of an intermittent stream bed.
One commenter supported the removal of the definition given
proposed elimination of the 300 linear foot limit from the NWPs and the
exclusion of ephemeral streams from jurisdiction under the Navigable
Waters Protection Rule. One commenter objected to the removal of the
definition of intermittent streams since they are in the Navigable
Waters Protection Rule. One commenter opposed the definition's removal
based on opposition to removal of the 300 linear foot limit from the
NWPs. One commenter stated that the term should be retained because a
cumulative impacts analysis may include a determination of flow through
ephemeral and intermittent streams.
The Corps is removing this definition as proposed because this term
is no longer used in the text of the NWPs.
Loss of waters of the United States. The Corps proposed to
rearrange the sentences in this definition so that the sentence that
defines the loss of stream bed is moved to become the second sentence
of this definition. In addition, the Corps proposed to modify this
sentence to state that the stream bed would have to be permanently
adversely affected, to be consistent with the first sentence of this
definition. For consistency with the proposal to remove the 300 linear
foot limit for losses of stream bed from 21, 29, 39, 40, 42, 43, 44,
51, and 52, and rely on the \1/2\-acre limit and other tools to comply
with the statutory requirement that the NWPs only authorize those
activities that have
[[Page 2840]]
no more than minimal individual and cumulative adverse environmental
effects, the Corps proposed to remove ``linear feet'' from the third
sentence of this definition. This would provide consistency among the
various types of waters when applying the fourth sentence of this
definition, which states that the acreage loss of waters of the United
States is a threshold measurement of the impact to jurisdictional
waters for determining whether a project may qualify for an NWP.
One commenter stated that the Corps should not remove the words
``linear feet'' from the definition because of opposition to removing a
method of calculating stream loss relative to compensatory mitigation.
One commenter expressed support for the changes as it makes clear that
loss is limited to stream beds permanently adversely impacted. One
commenter said that removal of linear feet from the definition would
result in more than minimal adverse environmental effects. One
commenter stated that conversion of forested wetlands to other wetland
types should be included in the definition of permanent adverse effects
which is included in the ``loss of waters of the United States''
definition.
The Corps has removed the 300 linear foot limit for losses of
stream bed from NWPs 21, 29, 39, 40, 42, 43, 44, 50, 51, and 52.
Therefore, the Corps is removing ``linear feet'' from this definition.
The Corps declines to include the conversion of forested wetlands to
other wetland types in the definition of ``loss of waters of the United
States'' because those areas remain wetlands and they continue to
provide wetland functions.
This definition is adopted as proposed.
Navigable waters. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Non-tidal wetland. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Open water. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Ordinary high water mark. The Corps proposed to modify this
definition to be consistent with the definition in the Navigable Waters
Protection Rule defining ``waters of the United States'' (see 33 CFR
328.3(c)(7)). One commenter said that the definition includes only a
discussion of the stream bed and omits reference to the bank contrary
to the definition in other Clean Water Act rules and regulations. The
lateral extent of Clean Water Act jurisdiction ends at the ordinary
high water mark, not the bank, if no adjacent wetlands are present. See
33 CFR 328.4(c).
The definition is adopted as proposed.
Perennial stream. The Corps proposed to modify the definition of
``perennial stream'' to be consistent with the definition of
``perennial'' in the Navigable Waters Protection Rule defining ``waters
of the United States'' (see 33 CFR 328.3(c)(8)).
One commenter stated support for the proposed change because of the
elimination of the 300 linear foot limit for losses of stream bed and
changes made to the definition in the Navigable Waters Protection Rule.
One commenter said that the previous definition was clearer in
instances when perennial streams are diverted underground. One
commenter stated that the definition does not match the definition in
the Navigable Waters Protection Rule, and recommended changing the
definition to match that definition.
The Navigable Waters Protection Rule at 33 CFR 328.3(c)(8) defines
the term ``perennial'' not ``perennial stream.'' The Corps used the
definition of ``perennial'' at 33 CFR 328.3(c)(8) to modify the NWP
definition of ``perennial steam.''
The definition is adopted as proposed.
Practicable. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Pre-construction notification. The Corps did not propose any
changes to this definition. The Corps did not receive any comments on
the proposed definition. The definition is adopted as proposed.
Preservation. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Protected tribal resources. Because of the proposed changes to NWP
general condition 17, tribal rights, the Corps proposed to remove this
definition from the NWPs since this term is not in the text of the
proposed general condition. The term ``protected tribal resources''
does not appear elsewhere in the text of NWPs, general conditions, or
definitions, or in Section D, ``District Engineer's Decision.''
A few commenters opposed the removal of the definition because they
opposed changing the text of general condition 17. A few commenters
said that that removal of the definition and the change to general
condition 17 will result in substantial impacts to tribal waters,
treaty, trust and cultural resources. One commenter suggested adding
the definition to general condition 17.
The Corps is removing this definition as proposed because it is no
longer used in the text of the NWPs or the general conditions.
Re-establishment. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Rehabilitation. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Restoration. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Riffle and pool complex. The Corps did not propose any changes to
this definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Riparian areas. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Shellfish seeding. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Single and complete linear project. The Corps did not propose any
changes to this definition.
Many commenters stated support for retaining the definition given
longstanding presence in regulation, practice by the Corps and
upholding in court cases. Several commenters stated that the definition
violates the Clean Water Act Section 404(e) minimal impact limitation,
the National Environmental Policy Act the Endangered Species Act and
other statutes and regulations. A few commenters stated that the
definition recognizes ``that discharges of dredged or fill material
along a utility line, with narrow crossings of separate and distant
waters, will typically have minimal effects both on the individual
waters crossed and cumulatively on watersheds.'' One commenter
supported continued use of the definition but said
[[Page 2841]]
that it is vague and has led to inconsistent application among
districts, particularly relative to multiple crossings of a single
water with multiple channels. One commenter stated that the definition
is inconsistently applied and should be revised to require or strongly
promote the concept of ``multiple'' single and complete linear
projects. One commenter requested clarification of the definition to
allow a determination of permit requirements and compensatory
mitigation by the permittee.
The definition is consistent with the Corps' regulations at 33 CFR
330.2(i), which was promulgated in 1991, and with long-standing
practice for authorizing linear projects by NWP. This definition does
not violate the Clean Water Act, the National Environmental Policy Act,
or the Endangered Species Act. It is based on a regulation that was
promulgated in accordance with the Administrative Procedure Act.
District engineers have discretion in applying this definition, and in
identifying separate and distant crossings of waters of the United
States. Only the district engineer has the authority to require
compensatory mitigation for activities authorized by NWPs. The permit
applicant is responsible for submitting a mitigation plan to the
district engineer for consideration.
The definition is adopted as proposed.
Single and complete non-linear project. The Corps did not propose
any changes to this definition. The Corps did not receive any comments
on the proposed definition. The definition is adopted as proposed.
Stormwater management. The Corps did not propose any changes to
this definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Stormwater management facilities. The Corps did not propose any
changes to this definition. The Corps did not receive any comments on
the proposed definition. The definition is adopted as proposed.
Stream bed. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Stream channelization. The Corps did not propose any changes to
this definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Structure. The Corps did not propose any changes to this
definition. One commenter suggested that the definition be altered to
be consistent with language used in proposed new NWP C. Specifically,
the commenter, proposes replacing the example of ``power transmission
line'' with ``utility line'' so it includes other types of lines. The
Corps declines to make the suggested change to this definition because
it covers a wide variety of structures that may be authorized by NWPs.
The definition is adopted as proposed.
Tidal wetland. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Tribal lands. The Corps did not propose any changes to this
definition. One commenter stated that the definition of tribal Lands
used by the U.S. EPA and the Corps' definition is different and
suggested that they be revised to be consistent. This definition was
adopted from the 1998 Department of Defense American Indian and Alaska
Native Policy, so the Corps is retaining that definition.
The definition is adopted as proposed.
Tribal rights. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Vegetated shallows. The Corps did not propose any changes to this
definition. The Corps did not receive any comments on the proposed
definition. The definition is adopted as proposed.
Waterbody. The Corps did not propose any changes to this
definition. Several commenters said that the term ``waterbody'' can be
confused with ``water body,'' which describes both jurisdictional and
non-jurisdictional features, for example as used in the Navigable
Waters Protection Rule. The commenter suggested deletion of
``waterbody'' and instead use of ``waters of the United States'' to
avoid confusion. One commenter recommended removal of the last sentence
of this definition. The Corps declines to make the suggested changes,
except for the removal of the last sentence, because this term is used
through the NWPs. The definition of ``waters of the United States'' at
33 CFR 328.3 is used to identify waterbodies, including adjacent
wetlands.
The definition is adopted as proposed.
III. Compliance With Relevant Statutes
A. National Environmental Policy Act Compliance
The Corps has prepared a decision document for each NWP. Each
decision document contains an environmental assessment (EA) to fulfill
the requirements of the National Environmental Policy Act (NEPA). The
EA includes the public interest review described in 33 CFR part
320.4(b). The EA generally discusses the anticipated impacts the NWP
will have on the human environment and the Corps' public interest
review factors. If a proposed NWP authorizes discharges of dredged or
fill material into waters of the United States, the decision document
also includes an analysis conducted pursuant to the Clean Water Act
section 404(b)(1), in particular 40 CFR part 230.7. These decision
documents evaluate, from a national perspective, the environmental
effects of each NWP.
The final decision document for each NWP is available on the
internet at: www.regulations.gov (docket ID number COE-2020-0002) as
Supporting and Related Materials for this final rule. Before the 2021
NWPs go into effect, division engineers will issue supplemental
documents to evaluate environmental effects on a regional basis (e.g.,
a state or Corps district) and to determine whether regional conditions
are necessary to ensure that the NWPs will result in no more than
minimal individual and cumulative adverse environmental effects on a
regional basis. The supplemental documents are prepared by Corps
districts, but must be approved and issued by the appropriate division
engineer, since the NWP regulations at 33 CFR 330.5(c) state that the
division engineer has the authority to modify, suspend, or revoke NWP
authorizations in a specific geographic area within his or her
division. For some Corps districts, their geographic area of
responsibility covers an entire state. For other Corps districts, their
geographic area of responsibility may be based on watershed boundaries.
For some states, there may be more than one Corps district responsible
for implementing the Corps regulatory program, including the NWP
program. In states with more than one Corps district, there is a lead
Corps district responsible for preparing the supplemental decision
documents for all of the NWPs. The supplemental decision documents will
also discuss regional conditions imposed by division engineers to
protect the aquatic environment and other public interest review
factors and ensure that any
[[Page 2842]]
adverse environmental effects resulting from NWP activities in that
region will be no more than minimal, individually and cumulatively.
The Corps solicited comments on the draft national decision
documents, and any comments received were considered when preparing the
final decision documents for the NWPs.
Before the final NWPs go into effect, division engineers will issue
supplemental documents to evaluate environmental effects on a regional
basis (e.g., state or Corps district). The supplemental documents are
prepared by Corps districts, but must be approved and formally issued
by the appropriate division engineer, since the NWP regulations at 33
CFR 330.5(c) state that the division engineer has the authority to
modify, suspend, or revoke NWP authorizations for any specific
geographic area within his or her division. For some Corps districts,
their geographic area of responsibility covers an entire state. For
other states, there is more than one Corps district responsible for
implementing the Corps Regulatory Program, including the NWP program.
In those states, there is a lead Corps district responsible for
preparing the supplemental documents for all of the NWPs. The
supplemental documents will discuss regional conditions imposed by
division engineers to protect the aquatic environment and ensure that
any adverse environmental effects resulting from NWP activities in that
region will be no more than minimal, individually and cumulatively.
For the NWPs, the assessment of cumulative effects under the Corps'
public interest review occurs at three levels: National, regional, and
the verification stage. Each national NWP decision document includes a
national-scale cumulative effects analysis under the Corps' public
interest review. Each supplemental document has a cumulative effects
analysis under the Corps' public interest review conducted for a
region, which is usually a state or Corps district. When a district
engineer issues a verification letter in response to a PCN or a
voluntary request for a NWP verification, the district engineer
prepares a brief decision document. That decision document explains
whether the proposed NWP activity, after considering permit conditions
such as mitigation requirements, will result in no more than minimal
individual and cumulative adverse environmental effects.
If the NWP is not suspended or revoked in a state or a Corps
district, the supplemental document includes a certification that the
use of the NWP in that district, with any applicable regional
conditions, will result in no more than minimal cumulative adverse
environmental effects.
After the NWPs are issued or reissued and go into effect, district
engineers will monitor the use of these NWPs on a regional basis (e.g.,
within a watershed, county, state, Corps district or other appropriate
geographic area), to ensure that the use of a particular NWP is not
resulting in more than minimal cumulative adverse environmental
effects. The Corps staff that evaluate NWP PCNs that are required by
the text of the NWP or by NWP general conditions or regional conditions
imposed by division engineers, or voluntarily submitted to the Corps
district by project proponents to receive written NWP verifications,
often work in a particular geographic area and have an understanding of
the activities that have been authorized by NWPs, regional general
permits, and individual permits over time, as well as the current
environmental setting for that geographic area. If the Corps district
staff believe that the use of an NWP in that geographic region may be
approaching a threshold above which the cumulative adverse
environmental effects for that category of activities may be more than
minimal, the district engineer may either make a recommendation to the
division engineer to modify, suspend, or revoke the NWP authorization
in that geographic region in accordance with the procedures in 33 CFR
330.5(c). Alternatively, under the procedures at 33 CFR 330.5(d), the
district engineer may also modify, suspend, or revoke NWP
authorizations on a case-by-case basis to ensure that the NWP does not
authorize activities that result in more than minimal cumulative
adverse environmental effects.
A few commenters said that the Council on Environmental Quality's
amended NEPA regulations are currently being litigated, and that the
Corps should continue to apply the 1978 regulations. Several commenters
stated that an environmental assessment would conclude that a finding
of no significant impact cannot be achieved for the NWPs, and
therefore, an environmental impact statement must be prepared for the
issuance of the NWPs. Several commenters said that a reasonable range
of actual alternatives must be evaluated, including a no action
alternative, for each NWP. A few commenters said because NWPs are in
effect for five years, the Corps should include reasonably foreseeable
future actions. A few commenters stated the Corps decision documents
fail to take a ``hard look'' at direct, indirect, and cumulative
analysis required by NEPA, and that the Corps decision documents fail
to consider or analyze relevant factors necessary to determine
significance.
The Corps prepared NEPA components of the draft and final national
decision documents in accordance with the Council on Environmental
Quality's current NEPA regulations, published in the Federal Register
on July 16, 2020 (85 FR 43304). The commenters objecting to the
preparation of environmental assessments for the issuance of the NWPs
do not provide any substantive information backing their claims that
the issuance of the NWPs requires an environmental impact statement.
The national decision document prepared for each NWP issued by this
final rule discusses alternatives, consistent with CEQ's current NEPA
regulations at 40 CFR 1501.5(c). The national decision documents
examine the effects and impacts of the proposed action (i.e., the
issuance of the NWP by Corps Headquarters) consistent with the
definition of ``effects or impacts'' at 40 CFR 1508.1(g).
A few commenters said the decision documents somehow imply that the
NWPs provide site-specific NEPA analysis, but that the Corps does not
undertake any NEPA analysis at a project-specific level. One commenter
stated that the Corps cannot defer its NEPA obligations to consider
mitigation measures, public comments, or alternatives analysis to the
regional or project level review because there is no guarantee any
further NEPA analysis would occur. Several commenters said the national
decision documents do not provide an a NEPA-level cumulative effects
analysis, and that the Corps cannot defer the analysis at a later stage
of review.
The Corps did not defer any of its NEPA obligations during the
preparation of the national decision documents for these NWPs. No
further NEPA analysis is required for specific activities authorized by
NWPs because the Corps fulfills the requirements of NEPA when it
prepares an environmental assessment with a finding of no significant
impact for each NWP's national decision document, to inform the
decision whether to issue or reissue that NWP. The 2020 CEQ NEPA
regulations altered how cumulative effects are considered under NEPA
(see the definition of ``effects or impacts'' at 40 CFR 1508.1(g)). The
Corps considered the effects of the proposed action in its national
decision documents.
[[Page 2843]]
One commenter requested information on what type of NEPA assessment
has been completed to determine the effects on aquatic resources as a
result of the proposed changes, and what type of studies have been
performed to show these changes will not result in more than minimal
effects. One commenter stated the national decision documents do not
provide a list of agencies or persons consulted in the development of
the environmental assessment. One commenter said the national decision
documents do not include tribal interests or treaty responsibilities.
The Corps' NEPA assessment is provided in the national decision
document for each NWP. Further, the Corps considered public comments
received on the 2020 Proposal and on the draft national decision
documents. Tribal interests and treaty responsibilities are more
appropriately addressed through consultations between Corps districts
and tribes on matters related to the NWP program and its
implementation.
B. Compliance With Section 404(e) of the Clean Water Act
The NWPs are issued in accordance with Section 404(e) of the Clean
Water Act and 33 CFR part 330. These NWPs authorize categories of
activities that are similar in nature. The ``similar in nature''
requirement does not mean that activities authorized by an NWP must be
identical to each other. We believe that the ``categories of activities
that are similar in nature'' requirement in Clean Water Act section
404(e) is to be interpreted broadly, for practical implementation of
this general permit program.
Nationwide permits, as well as other general permits, are intended
to reduce administrative burdens on the Corps and the regulated public
while maintaining environmental protection, by efficiently authorizing
activities that have no more than minimal adverse environmental
effects, consistent with Congressional intent expressed in the 1977
amendments to the Federal Water Pollution Control Act. The NWPs provide
incentives for project proponents to minimize impacts to jurisdictional
waters and wetlands to qualify for NWP authorization instead of having
to apply for individual permits. Keeping the number of NWPs manageable
is a key component for making the NWPs protective of the environment
and streamlining the authorization process for those general categories
of activities that have no more than minimal individual and cumulative
adverse environmental effects.
The various terms and conditions of these NWPs, including the NWP
regulations at 33 CFR 330.1(d) and 330.4(e), allow district engineers
to exercise discretionary authority to modify, suspend, or revoke NWP
authorizations or to require individual permits, and ensure compliance
with section 404(e) of the Clean Water Act. For each NWP that may
authorize discharges of dredged or fill material into waters of the
United States, the national decision documents prepared by Corps
Headquarters include a 404(b)(1) Guidelines analysis. The supplemental
documents prepared by division engineers will discuss regional
circumstances to augment the 404(b)(1) Guidelines analyses in the
national decision documents. These 404(b)(1) Guidelines analyses are
conducted in accordance with 40 CFR part 230.7.
The 404(b)(1) Guidelines analyses in the national decision
documents also include cumulative effects analyses done in accordance
with 40 CFR 230.7(b) and 230.11(g). A 404(b)(1) Guidelines cumulative
effects analysis is provided in addition to the NEPA cumulative effects
analysis because the implementing regulations for NEPA and the
404(b)(1) Guidelines define ``cumulative impacts'' or ``cumulative
effects'' differently.
C. 2020 Revisions to the Definition of ``Waters of the United States''
(i.e., the Navigable Waters Protection Rule)
Corps general permits are not intended to make or imply a
conclusion or determination regarding what water bodies are or are not
subject to CWA jurisdiction. Instead, a Corps general permit merely
states that, if a person complies with all of the terms and conditions
of the general permit, that person's proposed discharges of dredged or
fill material into the waterbody will be consistent with the CWA, on
the ground that any such discharges either (1) are legally authorized
under the CWA (to the extent that the waterbody is subject to CWA
jurisdiction) or (2) are otherwise consistent with the CWA to the
extent that the waterbody is not jurisdictional under the CWA. The
Corps acknowledges that some members of the public may seek to comply
with the conditions of a general permit even for water bodies that are
not jurisdictional or may not be jurisdictional under the CWA. Such
practice, though not required, is not unlawful. The Corps is not
required to make a formal determination whether a particular wetland or
water is subject to jurisdiction under Section 404 of the Clean Water
Act or Section 10 of the Rivers and Harbors Act of 1899 before issuing
an individual permit or a general permit verification. Many project
proponents prefer the time savings that can occur when the Corps issues
an individual permit or general permit verification without expending
the time and resources needed to make a formal, definitive
determination whether those wetlands and waters are in fact
jurisdictional and thus regulated under Section 404 of the Clean Water
Act and/or Section 10 of the Rivers and Harbors Act of 1899.
On April 21, 2020, the U.S. Environmental Protection Agency (EPA)
and the Department of the Army published the Navigable Waters
Protection Rule, revising the definition of ``waters of the United
States'' (85 FR 22250). Specifically, this final rule revises the
Corps' regulations at 33 CFR part 328.3, where the definition of
``waters of the United States'' is located for the purposes of
implementing Section 404 of the Clean Water Act. On June 22, 2020, the
Navigable Waters Protection Rule became effective in all states and
jurisdictions except for the State of Colorado due to a federal
district court-issued stay in that state (the case is currently under
appeal). The rule has also been challenged in several other federal
district courts.
Please note that some of the NWPs could authorize activities that
involve the discharge of dredged or fill material into water bodies
that are not subject to CWA jurisdiction, or that may not be subject to
CWA jurisdiction. For example, a project proponent could proceed with
an NWP activity that does not require submission of a PCN to the Corps
in a non-jurisdictional water without getting a definitive
determination from the Corps that the wetland or waterbody is not a
water of the United States and thus not subject to CWA jurisdiction. As
another example, if a proposed NWP activity requires pre-construction
notification, the district engineer could issue the NWP verification
based on the delineation of wetlands, other special aquatic sites, and
other waters provided with the PCN in accordance with paragraph (b)(5)
of NWP general condition 32, without the Corps making any formal
determination as to whether those wetlands, special aquatic sites, and
other waters are ``waters of the United States.''
During the pendency of any litigation challenging the Navigable
Waters Protection Rule, the NWPs will continue to authorize discharges
of dredged or fill material in all water bodies that are subject to CWA
jurisdiction, or that may
[[Page 2844]]
be subject to CWA jurisdiction, at the time those discharges occur.
Where a particular waterbody into which a person proposes to discharge
dredged or fill material is subject to CWA jurisdiction, compliance
with the terms and conditions of one or more NWPs, or an individual
permit, will be necessary. An affected party has the opportunity to
request an approved jurisdictional determination from the Corps if the
affected party would like the Corps' formal determination on the
jurisdictional status of a water or feature under the CWA.
D. Compliance With the Endangered Species Act
The NWP regulations at 33 CFR 330.4(f) and NWP general condition
18, endangered species, ensure that all activities authorized by NWPs
comply with section 7 of the Endangered Species Act (ESA). Those
regulations and general condition 18 require non-federal permittees to
submit PCNs for any activity that might affect listed species or
designated critical habitat, as well as species proposed for listing
and critical habitat proposed for such designation. When the district
engineer evaluates a PCN, he or she determines whether the proposed NWP
activity may affect listed species or designated critical habitat. The
Corps established the ``might affect'' threshold in 33 CFR 330.4(f)(2)
and paragraph (c) of general condition 18 because it is more stringent
than the ``may affect'' threshold for section 7 consultation in the
U.S. Fish and Wildlife Service's (FWS) and National Marine Fisheries
Service's (NMFS) ESA section 7 consultation regulations at 50 CFR part
402. The word ``might'' is defined as having ``less probability or
possibility'' than the word ``may'' (Merriam-Webster's Collegiate
Dictionary, 10th edition). Since ``might'' has a lower probability of
occurring, it is below the threshold (i.e., ``may affect'') that
triggers the requirement for ESA section 7 consultation for a proposed
Federal action. As discussed below, each year the Corps conducts
thousands of ESA section 7 consultations with the FWS and NMFS for
activities authorized by NWPs. In recent years, an average of more than
10,800 formal, informal, and programmatic ESA section 7 consultations
are conducted each year between the Corps and the FWS and/or NMFS in
response to NWP PCNs, including those activities that required PCNs
under paragraph (c) of general condition 18 under the ``might affect''
threshold.
If the project proponent is required to submit a PCN and the
proposed activity might affect listed species or designated critical
habitat, species proposed for listing, or critical habitat proposed for
such designation, the activity is not authorized by an NWP until either
the district engineer makes a ``no effect'' determination or makes a
``may affect'' determination and completes formal or informal ESA
section 7 consultation. The district engineer may also use a regional
programmatic consultation to comply with the requirements of section 7
of the ESA.
When evaluating a PCN, where necessary and appropriate, the Corps
district will either make a ``no effect'' determination or a ``may
affect'' determination. If the district engineer makes a ``may affect''
determination, she or he will notify the non-federal project proponent
and the activity is not authorized by the NWP until ESA Section 7
consultation has been completed. In making these determinations, the
district engineer will apply the definition of ``effects of the
action'' in the FWS's and NMFS's ESA consultation regulations at 50 CFR
402.02. If the district engineer initiates section 7 consultation with
the FWS and/or NMFS, that consultation will also consider ESA section 7
cumulative effects, in accordance with the definition of ``cumulative
effects'' at 50 CFR 402.02. If the non-federal project proponent does
not comply with 33 CFR 330.4(f)(2) and general condition 18, and does
not submit the required PCN, then the activity is not authorized by an
NWP. In such situations, it is an unauthorized activity and the Corps
district will determine an appropriate course of action under its
regulations at 33 CFR part 326 to respond to the unauthorized activity,
if and when the Corps learns about that unauthorized activity.
Federal agencies, including state agencies (e.g., certain state
Departments of Transportation) to which the Federal Highway
Administration has assigned its responsibilities for ESA section 7
consultation pursuant to 23 U.S.C. 327(a)(2)(B), are required to follow
their own procedures for complying with Section 7 of the ESA (see 33
CFR 330.4(f)(1) and paragraph (b) of general condition 18). This
includes circumstances where an NWP activity is part of a larger
overall federal project or action. The federal agency's ESA section 7
compliance covers the NWP activity because it is undertaking the NWP
activity and possibly other related activities that are part of a
larger overall federal project or action. For those NWPs that require
pre-construction notification for proposed activities, the federal
permittee is required to provide the district engineer with the
appropriate documentation to demonstrate compliance with section 7 of
the ESA. The district engineer will verify that the appropriate
documentation has been submitted. If the appropriate documentation has
not been submitted, additional ESA section 7 consultation may be
necessary for the proposed activity to fulfill both the federal
agency's and the Corps' obligations to comply with the ESA.
The only activities that potentially could be immediately
authorized by NWPs, assuming they meet all other applicable NWP
conditions, are activities that would have ``no effect'' on listed
species or designated critical habitat within the meaning of Section 7
of the ESA and its implementing regulations at 50 CFR part 402.
Therefore, the issuance or reissuance of NWPs does not require ESA
section 7 consultation because no activities authorized by any NWPs
``may affect'' listed species or critical habitat without first
completing activity-specific ESA Section 7 consultations with the
Services, as required by general condition 18 and 33 CFR 330.4(f).
Regional programmatic ESA section 7 consultations may also be used by
district engineers to satisfy the requirements of the NWPs in general
condition 18 and 33 CFR 330.4(f) if a proposed NWP activity is covered
by that regional programmatic consultation.
In the August 27, 2019, issue of the Federal Register (84 FR 44976)
the FWS and NMFS published a final rule that amended their regulations
for interagency cooperation under Section 7 of the ESA. That final rule
went into effect on October 28, 2019. With respect to making effects
determinations for proposed federal actions, such as activities
authorized by NWPs, the FWS and NMFS made two important changes to 50
CFR part 402: (a) Introducing the term ``consequences'' to help define
what is an effect under ESA section 7, and (b) emphasizing that to be
considered an ``effect of the action'' under section 7 consultation,
the consequences caused by the action would not occur but for the
proposed action and must be reasonably certain to occur (see 84 FR
44977). Further clarification of ``activities that are reasonably
certain to occur'' and ``consequences caused by the proposed action''
were provided by the FWS and NMFS in rule text added at 50 CFR
402.17(a) and (b), respectively.
Applying the 2019 amendments to the section 7 regulations to the
NWP program, consequences to listed species and designated critical
habitat caused
[[Page 2845]]
by proposed NWP activities must be reasonably certain to occur. In the
preamble to their final rule, the FWS and NMFS stated that for a
``consequence of an activity to be considered reasonably certain to
occur, the determination must be based on clear and substantial
information'' (see 84 FR 44977). The FWS and NMFS explained that
``clear and substantial'' means that there has to be a firm basis for
supporting a conclusion that a consequence of a federal action is
reasonably certain to occur. The determination that a consequence is
reasonably certain to occur should not be based on speculation or
conjecture, and the information used to make that determination should
have a ``degree of certitude'' (see 84 FR 44977). The Corps will apply
these considerations when evaluating pre-construction notifications for
proposed NWP activities.
When the district engineer receives a pre-construction notification
for a proposed NWP activity, he or she is responsible for applying the
current definition of ``effect of the action'' to the proposed NWP
activity and to determine the consequences caused by the proposed
action and which activities are reasonably certain to occur. The
district engineer determines whether the proposed NWP activity ``may
affect'' listed species or designated critical habitat and initiates
formal or informal section 7 consultation, unless she or he determines
that the proposed NWP activity will have ``no effect'' on listed
species or designated critical habitat. As a general rule, the district
engineer documents his or her ``no effect'' determination in writing
for every pre-construction notification that the district engineer
receives and responds to.
The NWP program has been structured, through the requirements of
NWP general condition 18 and 33 CFR 330.4(f), to focus ESA section 7
compliance at the activity-specific and regional levels. Each year, an
average of more than 10,800 formal, informal, and regional programmatic
ESA section 7 consultations are conducted by Corps districts with the
FWS and/or NMFS in response to NWP PCNs for specific NWP activities
(see below). Focusing ESA section 7 compliance at the activity-specific
scale and regional programmatic scale is more efficient for the
permittees, the Corps, and the FWS and NMFS, than doing so at the
national level because of the similarities in ecosystem characteristics
and associated listed species and critical habitat within a particular
region.
For a proposed NWP activity that may affect listed species or
designated critical habitat, a biological opinion with an incidental
take statement is needed for the NWP activity to go forward unless the
FWS or NMFS issued a written concurrence that the proposed NWP activity
is not likely to adversely affect listed species or designated critical
habitat. It is through activity-specific section 7 consultations and
regional programmatic section 7 consultations between the Corps and the
FWS and NMFS that effective protection of listed species and their
designated critical habitat is achieved.
After applying the current ESA section 7 regulations at 50 CFR part
402 to the NWP rulemaking process, the Corps continues to believe that
the issuance or reissuance of the NWPs has ``no effect'' on listed
species or designated critical habitat, and that the ESA section 7
compliance is most effectively achieved by applying the requirements of
general condition 18 and 33 CFR 330.4(f) to specific proposed NWP
activities that are identified after the NWPs are issued and go into
effect. Compliance with the requirements of ESA section 7 can also be
achieved by district engineers applying appropriate formal or informal
regional programmatic ESA section 7 consultations that have been
developed by Corps districts with regional offices of the FWS and NMFS.
Section 7 of the Endangered Species Act requires each federal
agency to ensure, through consultation with the Services, that ``any
action authorized, funded, or carried out'' by that agency ``is not
likely to jeopardize the continued existence of listed species or
adversely modify designated critical habitat.'' (See 16 U.S.C.
1536(a)(2).) Accordingly, the Services' section 7 regulations specify
that an action agency must ensure that the action ``it authorizes,''
including authorization by permit, does not cause jeopardy or adverse
modification. (See 50 CFR 402.01(a) and 402.02). Thus, in assessing
application of ESA section 7 to NWPs issued or reissued by the Corps,
the proper focus is on the nature and extent of the specific activities
``authorized'' by the NWPs and the timing of that authorization.
The issuance or reissuance of the NWPs by the Chief of Engineers
imposes express limitations on activities authorized by these NWPs.
These limitations are imposed by the NWP terms and conditions,
including the general conditions that apply to all NWPs regardless of
whether pre-construction notification is required by a specific NWP.
With respect to listed species and critical habitat, general condition
18 expressly prohibits any activity ``which `may affect' a listed
species or designated critical habitat, unless section 7 consultation
addressing the effects of the proposed activity has been completed.''
General condition 18 also states that if an activity ``might affect'' a
listed species or designated critical habitat (or a species proposed
for listing or critical habitat proposed for such designation), a non-
federal applicant must submit a PCN and ``shall not begin work on the
activity until notified by the district engineer that the requirements
of the ESA have been satisfied and that the activity is authorized.''
In addition, 33 CFR 330.4(f)(2) imposes a PCN requirement for proposed
NWP activities by non-federal permittees where listed species (or
species proposed for listing) or critical habitat might be affected or
are in the vicinity of the proposed NWP activity. Section 330.4(f)(2)
also prohibits those permittees from beginning the NWP activity until
notified by the district engineer that the requirements of the ESA have
been satisfied and that the activity is authorized. Permit applicants
that are Federal agencies must and will follow their own requirements
for complying with the ESA (see 33 CFR 330.4(f)(1)).
Thus, because no NWP can or does authorize an activity that may
affect a listed species or critical habitat absent an activity-specific
ESA section 7 consultation or applicable regional programmatic ESA
section 7 consultation, and because any activity that may affect a
listed species or critical habitat must undergo an activity-specific
consultation or be in compliance with a regional programmatic ESA
section 7 consultation before the district engineer can verify that the
activity is authorized by an NWP, the issuance or reissuance of NWPs
has ``no effect'' on listed species or critical habitat. Accordingly,
the action being ``authorized'' by the Corps (i.e., the issuance or re-
issuance of the NWPs themselves) has no effect on listed species or
critical habitat.
To help ensure protection of listed species and critical habitat,
general condition 18 and 33 CFR 330.4(f) establish a more stringent
threshold than the threshold set forth in the Services' ESA section 7
regulations for initiation of section 7 consultation. Specifically,
while section 7 consultation must be initiated for any activity that
``may affect'' listed species or critical habitat, for non-federal
permittees general condition 18 require submission of a PCN to the
Corps if ``any listed species (or species proposed
[[Page 2846]]
for listing) or designated critical habitat might be affected or is in
the vicinity of the activity, or if the activity is located in
designated critical habitat'' or critical habitat proposed for such
designation, and prohibits work until ``notified by the district
engineer that the requirements of the ESA have been satisfied and that
the activity is authorized.'' (See paragraph (c) of general condition
18.) The PCN must ``include the name(s) of the endangered or threatened
species (or species proposed for listing) that might be affected by the
proposed work or that utilize the designated critical habitat (or
critical habitat proposed for such designation) that might be affected
by the proposed work.'' (See paragraph (b)(7) of the ``Pre-Construction
Notification'' general condition.) Paragraph (f) of general condition
18 notes that information on the location of listed species and their
critical habitat can be obtained from the Services directly or from
their websites.
General condition 18 makes it clear to project proponents that an
NWP does not authorize the ``take'' of an endangered or threatened
species. Paragraph (e) of general condition 18 also states that a
separate authorization (e.g., an ESA section 10 permit or a biological
opinion with an ``incidental take statement'') is required to take a
listed species. In addition, paragraph (a) of general condition 18
states that no activity is authorized by an NWP which is likely to
``directly or indirectly jeopardize the continued existence of a
threatened or endangered species or a species proposed for such
designation'' or ``which will directly or indirectly destroy or
adversely modify the critical habitat of such species.'' Such
activities would require district engineers to exercise their
discretionary authority and subject the proposed activity to the
individual permit review process, because an activity that would
jeopardize the continued existence of a listed species, or a species
proposed for listing, or that would destroy or adversely modify the
critical habitat of such species would not result in no more than
minimal adverse environmental effects and thus cannot be authorized by
an NWP.
The Corps' NWP regulations at 33 CFR 330.1(c) state that an
``activity is authorized under an NWP only if that activity and the
permittee satisfy all of the NWP's terms and conditions.'' Thus, if a
project proponent moves forward with an activity that ``might affect''
an ESA listed species without complying with the PCN or other
requirements of general condition 18, the activity is not authorized
under the CWA. In this case, the project proponent could be subject to
enforcement action and penalties under the CWA. In addition, if the
unauthorized activity results in a ``take'' of listed species as
defined by the ESA and its implementing regulations, then he or she
could be subject to penalties, enforcement actions, and other actions
by the FWS or NMFS under section 11 of the ESA.
For listed species (and species proposed for listing) under the
jurisdiction of the FWS, information on listed species that may be
present in the vicinity of a proposed activity is available through the
Information Planning and Consultation (IPaC) system,\4\ an on-line
project planning tool developed and maintained by the FWS.

During the process for developing regional conditions, Corps
districts collaborate with FWS and/or NMFS regional or field offices to
identify regional conditions that can provide additional assurance of
compliance with general condition 18 and 33 CFR 330.4(f)(2). Such
regional conditions can add PCN requirements to one or more NWPs in
areas inhabited by listed species or where designated critical habitat
occurs. Regional conditions can also be used to establish time-of-year
restrictions when no NWP activity can take place to ensure that
individuals of listed species are not adversely affected by such
activities. Corps districts will continue to consider through regional
collaborations and consultations, local initiatives, or other
cooperative efforts additional information and measures to ensure
protection of listed species and critical habitat, the requirements
established by general condition 18 (which apply to all uses of all
NWPs), and other provisions of the Corps regulations ensure full
compliance with ESA section 7.
Corps district office personnel meet with local representatives of
the FWS and NMFS to establish or modify existing procedures, where
necessary, to ensure that the Corps has the latest information
regarding the existence and location of any threatened or endangered
species or their critical habitat, including species proposed for
listing or critical habitat proposed for such designation. Corps
districts can also establish, through local procedures or other means,
additional safeguards that ensure compliance with the ESA. Through
formal ESA section 7 consultation, or through other coordination with
the FWS and/or the NMFS, as appropriate, the Corps establishes
procedures to ensure that NWP activities will not jeopardize any
threatened and endangered species or result in the destruction or
adverse modification of designated critical habitat. Such procedures
may result in the development of regional conditions added to the NWP
by the division engineer, or in activity-specific conditions to be
added to an NWP authorization by the district engineer.
The Corps has prepared a biological assessment for this rulemaking
action. The biological assessment concludes that the issuance or
reissuance of NWPs has ``no effect'' on listed species and designated
critical habitat and does not require ESA section 7 consultation. This
conclusion was reached because no activities authorized by any NWPs
``may affect'' listed species or critical habitat without first
completing activity-specific ESA Section 7 consultations with the
Services, as required by general condition 18 and 33 CFR 330.4(f).
Based on the fact that NWP issuance or reissuance of the NWPs is
contingent upon any proposed NWP activity that ``may affect'' listed
species or critical habitat undergoing an activity-specific or regional
programmatic ESA section 7 consultation, there is no requirement that
the Corps undertake consultation for the NWP program. The national
programmatic consultations conducted in the past for the NWP program
were voluntary consultations despite the inclusion of procedures to
ensure consultation under Section 7 for proposed NWP activities that
may affect listed species or designated critical habitat. Regional
programmatic consultations can be conducted voluntarily by Corps
districts and regional or local offices of the FWS and/or NMFS to
tailor regional conditions and procedures to ensure the ``might
affect'' threshold is implemented consistently and effectively.
Examples of regional programmatic consultations currently in
effect, with the applicable Service the Corps consulted with, include:
The Standard Local Operating Procedures for Endangered Species in
Mississippi (2017--FWS); the Endangered Species Act Section 7
Programmatic Biological Opinion and Magnuson-Stevens Fishery
Conservation and Management Act Essential Fish Habitat Consultation for
Tidal Area Restoration Authorized, Funded, or Implemented by the Corps
of Engineers, Federal Emergency Management Agency, and Federal Highways
Administration, in Oregon and the Lower Columbia River (NMFS--2018);
the U.S. Army Corps of Engineers Jacksonville District's Programmatic
Biological Opinion (JAXBO) (NMFS--2017); Missouri Bat Programmatic
[[Page 2847]]
Informal Consultation Framework (FWS--2019); Revised Programmatic
Biological/Conference Opinion for bridge and culvert repair and
replacement projects affecting the Dwarf Wedgemussel, Tar River
Spinymussel, Yellow Lance and Atlantic Pigtoe. Programmatic Conference
Opinion (PCO) for Bridge and Culvert Replacement/Repairs/
Rehabilitations in Eastern North Carolina, NCDOT Divisions 1-8 (FWS--
2018); and the Corps and NOAA Fisheries Greater Atlantic Regional
Fisheries Office (GARFO) Not Likely to Adversely Affect Program
Programmatic Consultation (NMFS--2017).
The programmatic ESA section 7 consultations that the Corps
conducted for the 2007 and 2012 NWPs were voluntary consultations. The
voluntary programmatic consultation conducted with the NMFS for the
2012 NWPs resulted in a biological opinion issued on February 15, 2012,
which was replaced by a new biological opinion issued on November 24,
2014. A new biological opinion was issued by NMFS after the proposed
action was modified and triggered re-initiation of that programmatic
consultation. The programmatic consultation on the 2012 NWPs with the
FWS did not result in a biological opinion. For the 2017 NWPs, the
Corps did not request a national programmatic consultation.
In the Corps Regulatory Program's automated information system
(ORM), the Corps collects data on all individual permit applications,
all NWP PCNs, all voluntary requests for NWP verifications where the
NWP or general conditions do not require PCNs, and all verifications of
activities authorized by regional general permits. For all written
authorizations issued by the Corps, the collected data include
authorized impacts and required compensatory mitigation, as well as
information on all consultations conducted under section 7 of the ESA.
Every year, the Corps evaluates approximately 35,000 NWP PCNs and
requests for NWP verifications for activities that do not require PCNs,
and provides written verifications for those activities when district
engineers determine those activities result in no more than minimal
adverse environmental effects. During the evaluation process, district
engineers assess potential impacts to listed species and critical
habitat and conduct section 7 consultations whenever they determine
proposed NWP activities ``may affect'' listed species or critical
habitat. District engineers will exercise discretionary authority and
require individual permits when proposed NWP activities will result in
more than minimal adverse environmental effects.
Each year, the Corps conducts thousands of ESA section 7
consultations with the FWS and NMFS for activities authorized by NWPs.
These section 7 consultations are tracked in ORM. In FY 2018 (October
1, 2017 to September 30, 2018), Corps districts conducted 640 formal
consultations and 3,048 informal consultations under ESA section 7 for
NWP PCNs. During that time period, the Corps also used regional
programmatic consultations for 7,148 NWP PCNs to comply with ESA
section 7. Therefore, each year an average of more than 10,800 formal,
informal, and programmatic ESA section 7 consultations are conducted
between the Corps and the FWS and/or NMFS in response to NWP PCNs,
including those activities that required PCNs under paragraph (c) of
general condition 18. For a linear project authorized by NWPs 12 or 14,
where the district engineer determines that one or more crossings of
waters of the United States that require Corps authorization ``may
affect'' listed species or designated critical habitat, the district
engineer initiates a single section 7 consultation with the FWS and/or
NMFS for all of those crossings that he or she determines ``may
affect'' listed species or designate critical habitat. The number of
section 7 consultations provided above represents the number of NWP
PCNs that required some form of ESA section 7 consultation, not the
number of single and complete projects authorized by an NWP that may be
included in a single PCN. A single NWP PCN may include more than one
single and complete project, especially if it is for a linear project
such as a utility line or road with multiple separate and distant
crossings of jurisdictional waters and wetlands from its point of
origin to its terminal point.
During the process for reissuing the NWPs, Corps districts
coordinated with regional and field offices of the FWS and NMFS to
discuss whether new or modified regional conditions should be imposed
on the NWPs to improve implementation of the ``might effect'' threshold
and improve protection of listed species and designated critical
habitat and ensure that the NWPs only authorize activities with no more
than minimal individual and cumulative adverse environmental effects.
Regional conditions must comply with the Corps' regulations at 33 CFR
325.4 for adding permit conditions to DA authorizations. The Corps
decides whether suggested regional conditions identified during this
coordination are appropriate for the NWPs. During this coordination,
other tools, such as additional regional programmatic consultations or
standard local operating procedures, might be developed by the Corps,
FWS, and NMFS to facilitate compliance with the ESA while streamlining
the process for authorizing activities under the NWPs. Section 7
consultation on regional conditions occurs only when a Corps districts
makes a ``may affect'' determination and initiates formal or informal
section 7 consultation with the FWS and/or NMFS, depending on the
species that may be affected. Otherwise, the Corps district coordinates
the regional conditions with the FWS and/or NMFS. Regional conditions,
standard local operating procedures, and regional programmatic
consultations developed by the Corps, FWS, and NMFS are important tools
for protecting listed species and critical habitat and helping to
tailor the NWP program to address specific species, their habitats, and
the stressors that affect those species.
The Corps received numerous comments regarding compliance with the
Endangered Species Act for both the rulemaking process for issuing,
reissuing, and modifying the NWPs by Corps Headquarters, and compliance
for specific activities authorized by NWPs.
Many commenters expressed support for the Corps' current method of
ESA compliance without need for a national programmatic section 7
consultation. These commenters said that the requirements of general
condition 18 provide a sufficiently low threshold to trigger necessary
ESA section 7 consultations for NWP activities. Many commenters said
that there is no requirement for the Corps to consult under the ESA for
the reissuance of the NWPs because the reissuance of the NWPs has no
effect on listed species and consultation for each NWP activity occurs
as necessary. One commenter suggested that the Corps voluntarily
consult on reissuance of the NWPs to provide regulatory certainty to
the business community, and said that this voluntary consultation
should not delay issuance of a final rule. Many commenters expressed
opposition to reissuing the NWPs without completing a national
programmatic ESA section 7 consultation and addressing cumulative
impacts to listed species. Several commenters stated that the Corps had
failed to ensure that NWP activities are not likely to jeopardize the
continued existence of listed species or adversely modify or destroy
critical habitat, in violation of the ESA. A few commenters said that
the Corps' programmatic ``no effect'' determination for the NWPs is in
error because it is arbitrary and
[[Page 2848]]
capricious, in violation of the ESA, and/or in violation of federal
court decisions.
With this final rule, the Corps is continuing to implement its
current approach to ESA section 7 compliance, through general condition
18 and 33 CFR 330.4(f). The Corps has determined that the issuance of
this final rule will have no effect on endangered or threatened species
or critical habitat, completed a Biological Assessment to inform that
conclusion, and therefore will not be submitting a request to the FWS
and NMFS for a voluntary national programmatic ESA section 7
consultation. The Corps will continue to comply with the requirements
of Section 7(a)(2) of the ESA through activity-specific and regional
programmatic section 7 consultations conducted between district
engineers and regional and field offices of the FWS and NMFS.
A few commenters stated that general 18 unlawfully delegates the
Corps' ESA section 7 responsibilities to permittees. By requiring
project proponents to submit PCNs if listed species ``might be''
affected, some commenters stated that the Corps unlawfully delegates
the initial effect determination to the permittee. A few commenters
said that the definition of agency ``action'' in the ESA which requires
ESA section 7(b) consultation includes programmatic actions such as the
Corps issuance of the NWPs. A few commenters said that formal
programmatic consultation between the Corps and the Services is
necessary to meet the requirements of the ESA, asserting that such
consultation allows for consideration of the cumulative impacts of a
program and guides implementation of the program by establishing
criteria to avoid adverse effects. These commenters also said that
project-specific consultation must then be undertaken for specific
actions under the program, which is when incidental take is authorized.
One commenter said that the Corps' programmatic ``no effect'' with
reliance on project specific consultation for compliance with the ESA
is in error as it does not address cumulative impacts to species. The
commenter further stated that this is clear based on past court cases,
a past national programmatic consultation with NMFS, and the Services'
listing decisions and critical habitat designations whereby they assess
activities permitted by NWP as a cause of the listing or designation
decision.
General condition 18 does not delegate the Corps' ESA section 7
responsibilities to permittees. Consultation under section 7(a)(2) of
the ESA is only required when a federal agency determines that its
proposed action may affect listed species or designated critical
habitat. As explained in this section of the final rule, the ``might
affect'' threshold in paragraph (c) of general condition 18 is lower
than the ``may affect'' threshold for triggering a requirement for
consultation with the FWS and/or NMFS. The district engineer, not the
permit applicant, is responsible for making a ``may effect'' or ``no
effect'' determination under ESA section 7. The non-federal permittee
is responsible for complying with paragraph (c) of general condition 18
and submitting a PCN to the district engineer when a proposed NWP
activity triggers one of the PCN thresholds in that paragraph.
As discussed above, the Corps evaluated the programmatic action of
rulemaking to issue these NWPs and determined that the issuance or
reissuance of the NWPs by Corps Headquarters has no effect on listed
species or designated critical habitat; that evaluation is documented
in a Biological Assessment that supports its no effect determination.
Therefore, an ESA section 7(a)(2) consultation with the FWS and NMFS is
not required on a national, programmatic level for the issuance or
reissuance of the NWPs in this final rule. The Corps considered the
effects of its proposed action (i.e., the issuance or reissuance of the
NWPs through the rulemaking process), including the cumulative effects
anticipated to be caused by that proposed action. Those cumulative
impacts include the projected use of the NWPs during the 5-year period
those NWPs are anticipated to be in effect, along with the estimated
impacts to jurisdictional waters and wetlands and other resources, and
the estimated compensatory mitigation required by district engineers to
offset the authorized impacts. When issuing or reissuing the NWPs, or
determining whether specific activities are authorized by an NWP, the
Corps considers the individual and cumulative adverse environmental
effects caused by those activities, including adverse environmental
effects to a variety of resources, including jurisdictional waters and
wetlands and the species that inhabit those waters and wetlands.
With respect to cumulative effects under ESA section 7, the FWS and
NMFS define ``cumulative effects'' as the ``effects of future state or
private activities, not involving Federal activities, that are
reasonably certain to occur within the action area of the Federal
action subject to consultation'' (see 50 CFR 402.02). The Corps does
not have the legal authority to regulate or control future state or
private actions that do not involve activities that require DA
authorization under Section 10 of the Rivers and Harbors Act of 1899 or
Section 404 of the Clean Water Act. Therefore, the Corps does not have
the authority or discretion to control cumulative effects to listed
species or designated critical habitat that are caused by future state
or private activities. Incidental take is addressed through activity-
specific and regional programmatic formal ESA section 7 section
consultations when district engineers determine proposed NWP activities
may affect listed species or designated critical habitat.
Previous national ESA section 7 programmatic consultations on the
NWPs were voluntary consultations. Even though some listing decisions
by the FWS or NMFS may have identified activities that may require DA
permits as one of the contributing factors to listing a particular
species as endangered or threatened under the ESA, those listing
decisions usually acknowledge that section 7 consultations will be
conducted for proposed federal actions that may affect those species,
including activities that require DA authorization under Section 10 of
the Rivers and Harbors Act of 1899 and Section 404 of the Clean Water
Act. An example is the final rule issued by NMFS on June 28, 2005, for
the final listing determinations for 16 evolutionary significant units
of west coast salmon (see 70 FR 37195).
One commenter suggested that the Corps require PCNs for all NWPs to
ensure that the Corps is consulting as necessary under the ESA and is
able to accurately track and evaluate cumulative impacts. One commenter
stated that there is no requirement for the Corps to consult under the
ESA for the NWPs but believes the Corps needs to rebut the findings in
the Montana district court case in the text of the rule for purposes of
future litigation. One commenter said that the Corps' ``no effect''
determination and deferral of ESA consultation until the project is
proposed is in alignment with recent changes to ESA implementing
regulations at 50 CFR 402.17(a) and (b). Specifically, these commenters
assert that the change to the ESA section 7 regulations require that
``program actions that are reasonably certain to occur'' and the
potential consequences of proposed actions be based on ``clear and
substantial information.'' Information that, the commenter argues, is
not available until the project and its location are proposed.
[[Page 2849]]
It is neither practical nor necessary to require PCNs for all
activities authorized by NWPs to ensure compliance with section 7 the
ESA. There are many activities authorized by the NWPs each year that
have no effect on listed species or designated critical habitat,
despite approximately 10,800 ESA section 7 consultations occurring
annually. Listed species are not uniformly distributed across the
United States and tend to be concentrated in specific geographic areas
(``hotspots'') (e.g., Evans et al. 2016), and there are areas in the
country with jurisdictional waters and wetlands that have no or few
listed species where NWP activities proceed with no effects to listed
species or critical habitat. In addition, requiring PCNs for all
activities authorized by NWPs would nearly double the number of PCNs
reviewed by Corps district each year. In Appendix A of the Regulatory
Impact Analysis for the 2020 Proposal, the Corps estimates that nearly
32,000 NWP activities proceed without PCNs each year. The Regulatory
Impact Analysis for the 2020 proposal is available in the
www.regulations.gov docket for this rule (docket number COE-2020-0002).
That increase in the Corps' workload could result in changes in the
effectiveness and efficiency in the review of PCNs by district
engineers, as well as their evaluations of other activities requiring
DA authorization, including activities authorized by individual permits
and regional general permits. The increase in the Corps' workload could
also affect its ability to conduct enforcement and compliance actions.
Finally, and as explained above, General Condition 18 addresses this
commenter's concerns regarding PCN requirements.
The Corps agrees that its ``no effect'' determination for the
issuance or reissuance of the NWPs complies with the ESA section 7
regulations at 50 CFR part 402, because section 7 consultation is not
required when a federal agency determines its proposed action will have
no effect on listed species or designated critical habitat. In the
biological assessment prepared by the Corps for this rulemaking
activity, the Corps presents a substantial amount of data to
demonstrate the actions it takes to comply with section 7 of the ESA,
including the number of formal and informal section 7 consultations it
conducts with the FWS and NMFS and the number of regional programmatic
consultations and other tools it has developed with the FWS and NMFS.
One commenter said that the when the Corps implements an incidental
take statement as a condition in its NWP verification it must undertake
a project specific NEPA analysis. One commenter stated that the
incidental take statement must be applied to entire project and not
just the areas over which the Corps has control and responsibility. If
not, the project proponent must obtain an ESA section 10(a)(1)(B)
permit from the Services to ensure compliance with the ESA. Absent
this, general condition 18 has the potential to continuously violate
the ESA.
When a district engineer adds conditions to an NWP authorization to
comply with the ESA or other federal laws, including terms and
conditions from reasonable and prudent measures identified in an
incidental take statement in a biological opinion that apply to the
activity authorized by an NWP, a project-specific NEPA analysis is not
required. The Corps complies with the requirements of NEPA when it
prepares environmental assessments in the national decision documents
for the issuance or reissuance of the NWPs by Corps Headquarters. The
activities to which an incidental take statement in a biological
opinion issued by the FWS or NMFS applies is dependent on project-
specific circumstances identified in that biological opinion. When the
FWS or NMFS write an incidental take statement for a biological
opinion, under section 7(b)(4)(iv) of the ESA they can assign
responsibility of specific terms and conditions of the incidental take
statement to the federal action agency (e.g., the Corps), the
applicant, or both taking into account their respective roles,
authorities, and responsibilities (see 84 FR 44977). Paragraph (f) of
general condition 18 addresses ESA section 10(a)(1)(B) incidental take
permits and their potential application for NWP activities.
The Corps has carefully considered and evaluated all comments that
were provided regarding this issue. The Corps reaffirms that its ``no
effect'' determination for the promulgation of the NWPs is correct and
appropriate, for the reasons explained above.
E. Compliance With the Essential Fish Habitat Provisions of the
Magnuson-Stevens Fishery Conservation and Management Act
The NWP Program's compliance with the essential fish habitat (EFH)
consultation requirements of the Magnuson-Stevens Fishery Conservation
and Management Act will be achieved through EFH consultations between
Corps districts and NMFS regional offices. This approach continues the
EFH Conservation Recommendations provided by NMFS Headquarters to Corps
Headquarters in 1999 for the NWP program. Corps districts that have EFH
designated within their geographic areas of responsibility will
coordinate with NMFS regional offices, to the extent necessary, to
develop NWP regional conditions that conserve EFH and are consistent
with the NMFS regional EFH Conservation Recommendations. Corps
districts will conduct consultations in accordance with the EFH
consultation regulations at 50 CFR 600.920.
One commenter said that consultation with NMFS needs to occur for
all NWPs used in essential fish habitat. The Corps continues to
implement the EFH Conservation Recommendation provided by NMFS in 1999.
In those Corps districts where essential fish habitat has been
designated, district engineers review PCNs for proposed NWP activities
to determine whether those proposed activities may adversely affect
essential fish habitat. If the district engineer determines a proposed
NWP activity may adversely affect essential fish habitat, she or he
initiates EFH consultation with the NMFS. Division engineers can add
PCN requirements via regional conditions to those NWPs that do not
require PCNs for all activities to ensure that EFH consultation is
conducted for proposed activities that may adversely affect EFH.
F. Compliance With Section 106 of the National Historic Preservation
Act
The NWP regulations at 33 CFR 330.4(g) and the ``Historic
Properties'' general condition (general condition 20), ensure that all
activities authorized by NWPs comply with section 106 of the NHPA. The
``Historic Properties'' general condition requires non-federal
permittees to submit PCNs for any activity that might have the
potential to cause effects to any historic properties listed on,
determined to be eligible for listing on, or potentially eligible for
listing on the National Register of Historic Places, including
previously unidentified properties. The Corps then evaluates the PCN
and makes an effect determination for the proposed NWP activity for the
purposes of NHPA section 106. We established the ``might have the
potential to cause effects'' threshold in paragraph (c) of the
``Historic Properties'' general condition to require PCNs for those
activities so that the district engineer can evaluate the proposed NWP
activity and determine whether it has no potential to cause effects to
historic properties or whether it has potential to cause effects to
historic properties and thus require section 106 consultation.
If the project proponent is required to submit a PCN and the
proposed activity might have the potential to cause effects
[[Page 2850]]
to historic properties, the activity is not authorized by an NWP until
either the Corps district makes a ``no potential to cause effects''
determination or completes NHPA section 106 consultation.
When evaluating a PCN, the Corps will either make a ``no potential
to cause effects'' determination or a ``no historic properties
affected,'' ``no adverse effect,'' or ``adverse effect'' determination.
If the Corps makes a ``no historic properties affected,'' ``no adverse
effect,'' or ``adverse effect'' determination, it will notify the non-
federal applicant and the activity is not authorized by an NWP until
NHPA Section 106 consultation has been completed. If the non-federal
project proponent does not comply with the ``Historic Properties''
general condition, and does not submit the required PCN, then the
activity is not authorized by an NWP. In such situations, it is an
unauthorized activity and the Corps district will determine an
appropriate course of action to respond to the unauthorized activity.
The only activities that are immediately authorized by NWPs are
``no potential to cause effect'' activities under section 106 of the
NHPA, its implementing regulations at 36 CFR part 800, and the Corps'
``Revised Interim Guidance for Implementing Appendix C of 33 CFR part
325 with the Revised Advisory Council on Historic Preservation
Regulations at 36 CFR part 800,'' dated April 25, 2005, and amended on
January 31, 2007. Therefore, the issuance or reissuance of NWPs does
not require NHPA section 106 consultation because no activities that
might have the potential to cause effects to historic properties can be
authorized by an NWP without first completing activity-specific NHPA
Section 106 consultations, as required by the ``Historic Properties''
general condition. Programmatic agreements (see 36 CFR 800.14(b)) may
also be used to satisfy the requirements of the NWPs in the ``Historic
Properties'' general condition if a proposed NWP activity is covered by
that programmatic agreement.
NHPA section 106 requires a federal agency that has authority to
license or permit any undertaking, to take into account the effect of
the undertaking on any district, site, building, structure, or object
that is included in or eligible for inclusion in the National Register,
prior to issuing a license or permit. The head of any such Federal
agency shall afford the Advisory Council on Historic Preservation a
reasonable opportunity to comment on the undertaking. Thus, in
assessing application of NHPA section 106 to NWPs issued or reissued by
the Corps, the proper focus is on the nature and extent of the specific
activities ``authorized'' by the NWPs and the timing of that
authorization.
The issuance or reissuance of the NWPs by the Chief of Engineers
imposes express limitations on activities authorized by those NWPs.
These limitations are imposed by the NWP terms and conditions,
including the general conditions that apply to all NWPs regardless of
whether pre-construction notification is required. With respect to
historic properties, the ``Historic Properties'' general condition
expressly prohibits any activity that ``may have the potential to cause
effects to properties listed, or eligible for listing, in the National
Register of Historic Places,'' until the requirements of section 106 of
the NHPA have been satisfied. The ``Historic Properties'' general
condition also states that if an activity ``might have the potential to
cause effects'' to any historic properties, a non-federal applicant
must submit a PCN and ``shall not begin the activity until notified by
the district engineer either that the activity has no potential to
cause effects to historic properties or that consultation under Section
106 of the NHPA has been completed.'' Permit applicants that are
Federal agencies should follow their own requirements for complying
with section 106 of the NHPA (see 33 CFR 330.4(g)(1) and paragraph (b)
of the ``Historic Properties'' general condition).
Thus, because no NWP can or does authorize an activity that may
have the potential to cause effects to historic properties, and because
any activity that may have the potential to cause effects to historic
properties must undergo an activity-specific section 106 consultation
(unless that activity is covered under a programmatic agreement) before
the district engineer can verify that the activity is authorized by an
NWP, the issuance or reissuance of NWPs has ``no potential to cause
effects'' on historic properties. Accordingly, the action being
``authorized'' by the Corps, which is the issuance or re-issuance of
the NWPs by Corps Headquarters, has no potential to cause effects on
historic properties.
To help ensure protection of historic properties, the ``Historic
Properties'' general condition establishes a higher threshold than the
threshold set forth in the Advisory Council's NHPA section 106
regulations for initiation of section 106 consultation. Specifically,
while section 106 consultation must be initiated for any activity that
``has the potential to cause effects to'' historic properties, for non-
federal permittees the ``Historic Properties'' general condition
requires submission of a PCN to the Corps if ``the NWP activity might
have the potential to cause effects to any historic properties listed
on, determined to be eligible for listing on, or potentially eligible
for listing on the National Register of Historic Places, including
previously unidentified properties.'' The ``Historic Properties''
general condition also prohibits the proponent from conducting the NWP
activity ``until notified by the district engineer either that the
activity has no potential to cause effects to historic properties or
that consultation under Section 106 of the NHPA has been completed.''
(See paragraph (c) of the ``Historic Properties'' general condition.)
The PCN must ``state which historic property might have the potential
to be affected by the proposed activity or include a vicinity map
indicating the location of the historic property.'' (See paragraph
(b)(8) of the ``Pre-Construction Notification'' general condition.)
During the process for developing regional conditions, Corps
districts can coordinate or consult with State Historic Preservation
Officers, Tribal Historic Preservation Officers, and tribes to identify
regional conditions that can provide additional assurance of compliance
with the ``Historic Properties'' general condition and 33 CFR
330.4(g)(2) for NWP activities undertaken by non-federal permittees.
Such regional conditions can add PCN requirements to one or more NWPs
where historic properties occur. Corps districts will continue to
consider through regional consultations, local initiatives, or other
cooperative efforts and additional information and measures to ensure
protection of historic properties, the requirements established by the
``Historic Properties'' general condition (which apply to all uses of
all NWPs), and other provisions of the Corps regulations and guidance
ensure full compliance with NHPA section 106.
Based on the fact that NWP issuance or reissuance has no potential
to cause effects on historic properties and that any activity that
``has the potential to cause effects'' to historic properties will
undergo activity-specific NHPA section 106 consultation, there is no
requirement that the Corps undertake programmatic consultation for the
NWP program. Regional programmatic agreements can be established by
Corps districts and State Historic Preservation Officers and/or Tribal
Historic Preservation Officers to comply with the requirements of
section 106 of the NHPA.
[[Page 2851]]
One commenter stated the reissuance of the NWPs does not require
Section 106 NHPA consultation, but specific activities may require
section 106 consultation. One commenter said the Corps should
programmatically address the potential adverse effects from
undertakings permitted pursuant to the NWPs either by creating a
national programmatic agreement or a division-specific programmatic
agreement. One commenter stated that the Corps' position that effects
to historic properties would be evaluated on an individual activity
phase is not consistent with the 36 CFR part 800 regulations. One
commenter disagreed with the Corps' position that the issuance or
reissuance of the NWPs has ``no potential to cause effect'' on historic
properties and does not require compliance with Section 106 of the
NHPA. This commenter said that reliance on general conditions 20, 21,
and 32 is not a substitute for appropriate compliance with section 106
in individual cases.
For most NWP activities, the need to conduct NHPA section 106 is
determined on a case-by-case basis, as district engineers evaluate PCNs
for proposed NWP activities, including PCNs submitted by non-federal
permittees under paragraph (c) of general condition 20. The Corps
believes that programmatic agreements for section 106 compliance are
more appropriately developed at a regional level, between Corps
districts and State Historic Preservation Officers and Tribal Historic
Preservation Officers. The Advisory Council on Historic Preservation's
regulations provide for section 106 consultation on a case-by-case
basis, although it includes provisions for federal agency program
alternatives, including alternative procedures and programmatic
agreements (see 36 CFR 800.14). With respect to section 106 of the
NHPA, the only activities immediately authorized by an NWP are those
activities that have no potential to cause effects to historic
properties. Paragraph (c) of general condition 20 requires non-federal
permittees to submit PCNs for any proposed NWP activities that might
have the potential to cause effects to historic properties. District
engineers review these PCNs to determine whether NHPA section 106
consultation is required for a proposed NWP activity.
Several commenters stated that Appendix C to 33 CFR part 325 and
the 2005 and 2007 interim guidance documents issued by the Corps does
not constitute an acceptable federal agency program alternative under
36 CFR 800.14. One commenter said that the Corps does not have the
authority under the Clean Water Act and the River and Harbors Act of
1899 to promulgate its own regulations for compliance with Section 106
of the National Historic Preservation Act (i.e., Appendix C to 33 CFR
part 325) rather than complying with 36 CFR part 800.
The Corps continues to use Appendix C and the 2005 and 2007 interim
guidance to comply with section 106 of the NHPA. Section
110(a)(2)(E)(i) of the NHPA states that federal agencies can develop
their own procedures for complying with section 106 as long as those
procedures are consistent with the regulations issued by the Advisory
Council on Historic Preservation.
A few commenters stated the NWPs and the general conditions violate
the NHPA by delegating the effects determination to non-federal
permittees by allowing permittees to make a determination of effect for
NWP activities that do not require PCNs. Several commenters said that
general condition 20 is inconsistent with the 36 CFR part 800
regulations. One commenter stated that general condition 20 does not
provide a standard by which the permittee must determine a PCN is
necessary because of potential effects to historic properties.
The NWPs and their general conditions do not delegate effects
determinations under section 106 of the NHPA to non-federal permittees.
Paragraph (c) of general condition 20 requires non-federal permittees
to submit PCNs to district engineers for any proposed NWP activity that
might have the potential to cause effects to historic properties.
District engineers will review those PCNs and determine whether section
106 NHPA consultation is required for proposed NWP activities. The
``might have the potential to cause effects'' to any historic property
is a standard to guide permittees as to when they need to submit PCNs
so that district engineers can determine whether section 106
consultation is required for a proposed NWP activity.
A few commenters said that the Corps' permit area (area of
potential effects) for section 106 compliance should not be limited to
the activity within waters of the United States that requires DA
authorization, and that the area of potential effects should encompass
the entire project that requires the permit. One commenter stated that
the Corps' limited permit area causes costly delays to the project
proponent when section 106 disputes are triggered, and that by limiting
the permit area, the Corps undertaking does not adequately consider
direct or indirect effect on historic properties.
The Corps' permit area or area of potential effects is limited to
those areas and activities where the Corps has control and
responsibility to address effects to historic properties through its
permitting authorities under Section 404 of the Clean Water Act and
Section 10 of the Rivers and Harbors Act of 1899. District engineers
work with permit applicants and other consulting parties to resolve
disagreements about permit areas for section 106 compliance. When
evaluating PCNs, district engineers consider direct and indirect
effects to historic properties.
A few commenters said that a federal agency must consult with the
Advisory Council on Historic Preservation, State Historic Preservation
Offices, Tribal Historic Preservation Officers, tribes, and Native
Hawaiian organization, where applicable, when effects to historic
properties cannot be fully determined, and said that if a PCN is not
warranted, these groups are not provided an opportunity to comment. One
commenter said that the Corps must afford the Advisory Council on
Historic Preservation a reasonable opportunity to comment on the
undertaking, and when no PCN is required for an NWP activity, there is
no consultation on the undertaking.
Non-federal permit applicants are responsible for complying with
general condition 20, including the requirement to submit PCNs for any
proposed NWP activity that might have the potential to cause effects to
historic properties, so that the district engineer can determine
whether section 106 consultation is required for proposed activity. If
the district engineer determines section 106 consultation is necessary,
she or he will identify consulting parties and initiate section 106
consultation with those consulting parties. District engineers provide
the Advisory Council on Historic Preservation with a reasonable
opportunity to comment when the Council enters the section 106 process
in accordance with Appendix A to 36 CFR part 800.
G. Section 401 of the Clean Water Act
A water quality certification issued by a state, authorized tribe,
or EPA, or a waiver thereof, is required by section 401 of the Clean
Water Act, for an activity authorized by an NWP which may result in a
discharge from a point source into waters of the United States. Water
quality certifications may be granted without conditions, granted with
conditions, denied, or waived for specific NWPs.
Nationwide permits 21, 29, 39, 40, 42, 43, and 50 would authorize
activities that may result in discharges to waters
[[Page 2852]]
of the United States and therefore section 401 water quality
certification or waiver is required for those NWPs. Nationwide permits
12, 48, 51, 52, 57, and 58 would authorize various activities, some of
which may result in a discharge to waters of the United States and
require section 401 water quality certification or waiver, and others
which may not. Nationwide permits 55, and 56 do not require section 401
water quality certification because they would authorize activities
which, in the opinion of the Corps, could not reasonably be expected to
result in a discharge into waters of the United States. In the case of
NWP 8, it only authorizes activities seaward of the territorial seas
where the Clean Water Act does not apply.
Prior to the issuance of the 16 NWPs, certifying authorities made
their decisions on whether to issue, deny, or waive water quality
certification (WQC) for the issuance of the NWPs. If a certifying
authority issued water quality certifications with conditions for the
issuance of these NWPs, district engineers reviewed the conditions in
those water quality certifications to determine whether they comply
with the requirements in 40 CFR 121.7(d). If the district engineer
determines that any condition in the water quality certification for
the issuance of the NWPs does not comply with the requirements of 40
CFR 121.7(d), and is waived pursuant to 40 CFR 121.9(d), the district
engineer will notify the certifying authority and the EPA Administrator
in accordance with 40 CFR 121.9(c). The conditions in the water quality
certification for the issuance of the NWP that comply with the
requirements of 40 CFR 121.7(d) and are not waived become conditions of
the NWP authorization in accordance with Section 401(d) of the Clean
Water Act.
If a certifying agency denies WQC for the issuance of an NWP, then
the proposed discharges are not authorized by that NWP unless and until
a project proponent obtains WQC for the specific discharge from the
certifying authority, or a waiver of WQC occurs.
In the 2020 Proposal, the Corps noted that EPA issued revisions to
its regulations governing the Clean Water Act section 401 certification
process on June 1, 2020. In the future, it may be necessary or
appropriate for the Corps to revise its own section 401 regulations,
including 33 CFR 330.4, in light of EPA's Clean Water Act Section 401
Certification Rule. The Corps invited comments from the public on
whether and, if so, when the Corps should revise those regulations in
light of the new EPA regulations.
In response to the proposed rule and the associated requests for
water quality certification, many certifying authorities requested an
extension of the 60-day reasonable period of time to review and certify
the proposed NWPs. A few commenters said that many states cannot comply
with the 60 days provided due to public participation requirements,
including public hearings. A few commenters stated that the 60-day
review period is not sufficient time to review the proposed NWPs
considering recent changes to EPA's regulations for Section 401 of the
Clean Water Act and the issuance of the final Navigable Waters
Protection Rule. One commenter voiced support for 60 days certifying
their complete WQC decision for the proposed NWPs. One commenter stated
that the 60-day reasonable period of time should be extended to 180
days to provide adequate time to review the proposed rule including the
proposed NWPs. One commenter said that the abbreviated timeline
undermines and limits state and tribal input. A few commenters said the
Corps should request certification on the final NWPs. One commenter
said that 60 days to act on the certification request is not consistent
with the terms of a 1992 settlement agreement between the Pennsylvania
Department of Environmental Resources and the Corps.
In light of the timeframe for issuing the final NWPs, the Corps did
not grant extensions to the 60-day reasonable period of time for water
quality certification. Section 401 of the Clean Water Act and EPA's
regulations at 40 CFR 121.6 give the Corps the authority to establish
the reasonable period of time. For this issuance of these NWPs, the
Corps complied with EPA's final rule, which was published in the
Federal Register on July 13, 2020, and went into effect on September
11, 2020. That final rule went into effect a few days before the
proposed NWPs were published in the Federal Register for public
comment. The Corps worked with the Commonwealth of Pennsylvania to
address the 1992 settlement agreement.
Many commenters said that the reasonable period of time for
certification of the NWPs should be extended until the final rule is
issued. A few commenters stated that certifying the proposed NWPs prior
to the NWPs being finalized is problematic as there are significant
proposed changes in the NWPs. Several commenters said that the
procedure is outside of the normal standard practice of certifying the
NWPs after the final NWPs are issued. Many commenters expressed concern
and disagreement over reviewing and certifying the proposed NWPs at the
same time. Several commenters said that water quality certification
conditions could change if the final NWPs are modified from the
proposed NWPs.
Section 401 of the Clean Water Act states that no permit shall be
issued until water quality certification has been obtained or waived.
Therefore, the water quality certification process must be completed
before the final NWPs are issued. That process is consistent with the
Corps' NWP regulations at 33 CFR 330.4(c)(1), which says that ``water
quality certification pursuant to section 401 of the Clean Water Act,
or waiver thereof, is required prior to the issuance or reissuance of
NWPs authorizing activities which may result in a discharge into waters
of the United States.'' The water quality certification regulations
issued by EPA this year also state that water quality certification
requests are made for proposed general permits, not the final general
permits. The regulations issued by EPA include no provisions for
modifying water quality certifications after the certifying authority
has acted on the federal agency's certification request. If the federal
agency is planning to make changes to the general permit in response to
public comments, those changes may trigger a requirement for a new
certification before the federal agency can issue the final general
permit (see 85 FR 42279).
A few commenters said that requesting state certification of the
proposed NWPs does not recognize that there may be changes to the final
NWPs based upon the public comments received. A few commenters stated
that they should have the opportunity to fully evaluate the final
version of the NWPs and modify their water quality certifications as
necessary. A few commenters expressed disagreement with the request to
certify the proposed NWPs and requested the Corps provide a reasonable
review time and issue the WQC on the final NWPs after any changes have
been made after considering public comments. A few commenters said that
water quality certifications may be issued conditionally and only valid
if the final NWPs are not different than the proposed NWPs. A few
commenters noted that the Corps' request to certify the proposed NWPs
is a departure from past practice whereby states issue water quality
certifications on the final NWPs before those NWPs go into effect.
As discussed above, certifying authorities must act on
certification requests before the Corps can issue the final NWPs. The
Corps acknowledges
[[Page 2853]]
that the water quality certification process for the 2020 Proposal is a
departure from past practice; however, it is consistent with section
401 and EPA's final certification regulation at 40 CFR part 121. In the
16 NWPs issued in this final rule, there were no substantive changes
that trigger a requirement for the Corps to submit new certification
requests for the NWPs.
A few commenters said that the separate review 60-day timeline for
water quality certification and the 90-day timeline for CZMA
consistency determinations bifurcates the review process and is
unnecessarily cumbersome and suggested that a joint 90-day review
period should be provided. The Corps established different review
periods for water quality certification and CZMA consistency
determinations because those are separate processes that are governed
by distinctly different laws and regulations. Section 401 of the Clean
Water Act gives the permitting authority the ability to establish the
reasonable period of time for a certify authority to act on a request
for water quality certification. The CZMA consistency determination
process is governed by regulations issued by the Department of Commerce
at 15 CFR part 930.
Several commenters stated that subsequent changes from the proposed
NWPs to the final NWPs may result in in missing or inappropriate
conditions and leave the certifying agencies with no opportunity to
remedy a deficient certification. One commenter said that changes
between the proposed NWPs and the final NWPs may require certifying
authorities to deny certification due to insufficient information. One
commenter stated that denying water quality certification for all of
the proposed NWPs would have significant implications for streamlining
federal permitting of discharges authorized by the NWPs. One commenter
said that should water quality certification for the issuance of the
NWPs be denied, there will be additional burdens on permittees. One
commenter said the Corps would need to request water quality
certification on the final NWPs to have valid water quality
certifications. One commenter said that some states operate under state
general permits where NWPs are revoked. This commenter noted that the
denied certifications for NWPs will raise conflicts and issues when
state general permits are reissued.
As discussed above, water quality certification decisions by
certifying authorities must be made before the Corps issues the final
NWPs. Certifying authorities can deny water quality certifications if
they believe they do not have sufficient information to issue water
quality certification (see 40 CFR 121.7(e)(2)). The Corps acknowledges
that denial of water quality certifications for the issuance of the
NWPs creates burdens on the regulated public in terms of having to
obtain water quality certifications or waivers for specific discharges
authorized by NWPs. The issuance of the NWPs by Corps Headquarters is
an independent process from the issuance of regional general permits by
district engineers.
One commenter stated a website where all final WQC conditions are
posted would be helpful. One commenter said the Corps should provide
proposed water quality certification conditions for the NWPs and let
the state agencies review those proposed conditions to make the
certification process for the NWPs. One commenter stated that the Corps
should not revise its water quality certification regulations.
After the final NWPs are issued and division engineers have
approved the final regional conditions for the NWPs, Corps districts
will issue public notices announcing the final regional conditions for
the NWPs and the disposition of water quality certifications and CZMA
consistency concurrences for the final NWPs. The Corps will post copies
of these district public notices in the www.regulations.gov docket for
this rulemaking action (docket number COE-2020-0002). It is the
certifying authorities' responsibility to develop conditions for their
water quality certifications for the issuance of the NWPs. The Corps
will be revising the provisions in its regulations for water quality
certification, to be consistent with EPA's new water quality
certification regulations.
H. Section 307 of the Coastal Zone Management Act (CZMA)
Any state with a federally-approved CZMA program must concur with
the Corps' determination that activities authorized by NWPs which are
within, or will have reasonably foreseeable effects on any land or
water uses or natural resources of, the state's coastal zone, are
consistent with the CZMA program to the maximum extent practicable.
Coastal Zone Management Act consistency concurrences may be issued
without conditions, issued with conditions, or denied for specific
NWPs.
Prior to the issuance of the 16 NWPs, states made their decisions
on whether to concur with or object to the Corps' CZMA consistency
determination for the issuance of the NWPs. If a state issued a
concurrence with conditions for the issuance of these NWPs, district
engineers reviewed the conditions in those consistency concurrences to
determine whether they comply with the Corps' regulations for permit
conditions at 33 CFR 325.4. If a state objected to the Corps' CZMA
consistency determination for the issuance of an NWP, then the activity
is not authorized by that NWP unless and until a project proponent
obtains a consistency concurrence from the state or a presumption of
concurrence occurs.
The Corps' CZMA consistency determination only applied to NWP
authorizations for activities that are within, or affect, any land,
water uses or natural resources of a State's coastal zone. A state's
coastal zone management plan may identify geographic areas in federal
waters on the outer continental shelf, where activities that require
federal permits conducted in those areas require consistency
certification from the state because they affect any coastal use or
resource. In its coastal zone management plan, the state may include an
outer continental shelf plan. An outer continental shelf plan is a plan
for ``the exploration or development of, or production from, any area
which has been leased under the Outer Continental Shelf Lands Act'' and
regulations issued under that Act (see 15 CFR 930.73). Activities
requiring federal permits that are not identified in the state's outer
continental shelf plan are considered unlisted activities. If the state
wants to review an unlisted activity under the CZMA, then it must
notify the applicant and the federal permitting agency that it intends
to review the proposed activity. Nationwide permit authorizations for
activities that are not within or would not affect a state's coastal
zone do not require the Corps' CZMA consistency determinations and thus
are not contingent on a State's concurrence with the Corps' consistency
determinations.
If a state objects to the Corps' CZMA consistency determination for
an NWP, then the affected activities are not authorized by an NWP
within that state until a project proponent obtains an individual CZMA
consistency concurrence, or sufficient time (i.e., six months) passes
after requesting a CZMA consistency concurrence for the applicant to
make a presumption of consistency, as provided in 33 CFR 330.4(d)(6).
However, when applicants request NWP verifications for activities that
require individual consistency concurrences, and the Corps determines
that those activities meet the terms and conditions of the NWP, in
accordance
[[Page 2854]]
with 33 CFR 330.6(a)(3)(iii) the Corps will issue provisional NWP
verification letters. The provisional verification letter will contain
general and regional conditions as well as any activity-specific
conditions the Corps determines are necessary for the NWP
authorization. The Corps will notify the applicant that he or she must
obtain an activity-specific CZMA consistency concurrence or a
presumption of concurrence before he or she is authorized to start work
in waters of the United States. That is, NWP authorization will be
contingent upon obtaining the necessary CZMA consistency concurrence
from the state, or a presumption of concurrence. Anyone wanting to
perform such activities where pre-construction notification to the
Corps is not required has an affirmative responsibility to present a
CZMA consistency determination to the appropriate state agency for
concurrence. Upon concurrence with such CZMA consistency determinations
by the state, the activity would be authorized by the NWP. This
requirement is provided at 33 CFR 330.4(d).
In response to the 2020 proposal several commenters said that the
Corps is providing a CZMA federal consistency determination for the
proposed rule and is asking the states to concur with a federal action
that is not final. These commenters said that if there are changes in
the final NWPs, those changes may result in missing or inappropriate
conditions and leave states with no opportunity to remedy deficiencies.
Several commenters stated that the Corps should have allowed comment on
the proposed rule prior to initiating the federal consistency review
process. A few commenters said there is a disconnect between the 60-
days allowed for water quality certifications and the 90-days allowed
for CZMA consistency reviews. One commenter requested an extension of
time until mid-January 2021 for the state to complete its review and
make its determinations.
The CZMA consistency concurrence process for the issuance of the
NWPs must be completed before the final NWPs are issued. The Department
of Commerce's CZMA regulations at 15 CFR 930.36(b)(1) state that the
federal agency's consistency determination shall be provided to state
agencies at least 90 days before final approval of the federal agency's
activity unless both the federal agency and the state agency agree to
an alternative notification schedule. Therefore, the CZMA consistency
concurrence process must be completed before the Corps issues the final
NWPs. If the Corps were to make substantial changes to the proposed
NWPs, then the Corps would conduct supplemental coordination with the
states. In these 16 final NWPs, the Corps did not make any substantial
changes that would trigger supplemental coordination with states. The
Corps acknowledges that under 15 CFR 930.41(a), it could have requested
responses from state agencies within 60 days of receipt of the Corps'
consistency determination and supporting information. Under 15 CFR
930.41(b), federal agencies are required to approve one extension
period of 15 days or less, if the state agency requests an extension of
time within the 60-day review period. The WQC and CZMA consistency
concurrence review periods are different because they are governed by
different regulations.
IV. Economic Impact
The NWPs are expected to increase the number of activities eligible
for NWP authorization, and reduce the number of activities that require
individual permits. The Corps estimates that the proposed NWPs will
authorize an 209 activities each year that would have otherwise
required an individual permit. While applying for a NWP may entail some
burden (namely, in the form of a PCN, when applicable), by authorizing
more activities by NWP, this proposal will reduce net burden for the
regulated public. Specifically, increasing the number of activities
that can be authorized by NWPs is expected to decrease compliance costs
for permit applicants since, as discussed below, the compliance costs
for obtaining NWP authorization are less than the compliance costs for
obtaining individual permits. In addition, the NWPs can incentivize
some project proponents to design their projects in such a way that
they would qualify for a NWP thereby reducing impacts to jurisdictional
waters and wetlands. In FY2018, the average time to receive an NWP
verification was 45 days from the date the Corps district receives a
complete PCN, compared to 264 days to receive a standard individual
permit after receipt of a complete permit application (see table 1.2 of
the regulatory impact analysis for this final rule, which is available
in the www.regulations.gov docket (docket number COE-2020-0002)).
As discussed in the Regulatory Impact Analysis for this proposed
rule, the Corps estimates that a permit applicant's compliance cost for
obtaining NWP authorization in 2019$ ranges from $4,412 to $14,705
(Institute for Water Resources (2001),\5\ adjusted for inflation using
the GDP deflator approach). The Corps estimates that a permit
applicant's compliance costs for obtaining an individual permit for a
proposed activity impacting up to 3 acres of wetland ranges from
$17,646 to $35,293 in 2019$. Considering how the proposed NWPs will
increase the number of activities authorized by an NWP each year, the
Corps estimates that the 16 final NWPs, when compared with the 2017
NWPs, will decrease compliance costs for the regulated public by
approximately $3 million per year. The Corps invited comment on the
assumptions and methodology used to calculate the compliance costs and
burden in general associated with the NWP and received no comments.

Several commenters stated that the Corps' Regulatory Impact
Analysis should include estimates of costs to the public due to losses
of wetland and stream functions and losses of ecosystem services caused
by activities authorized by NWPs. These commenters also said the
Regulatory Impact Analysis should address flooding that is exacerbated
by development in and around stream and wetland habitats. In addition,
these commenters stated that the Regulatory Impact Analysis should
evaluate the effect the proposed \1/10\-acre threshold for stream
mitigation in general condition 23 would have in terms of a reduction
in stream compensatory mitigation for NWP activities, and increases in
losses of headwater streams. These commenters also stated that the
Corps should analyze the effects of removing the PCN threshold for
mechanized land clearing of forested wetlands in oil or natural gas
pipeline rights-of-way from NWP 12. Several commenters said the
Regulatory Impact Analysis should also analyze the economic impacts of
the 2020 Proposal on the ecological restoration industry. One commenter
said that a cost-benefit analysis or reissuing the NWPs ahead of
schedule should be performed.
The Regulatory Impact Analysis prepared by the Corps for this final
rule was prepared in accordance with the Office of Management and
Budget's (OMB) Circular A-4 and OMB's Memorandum M-17-21 for
implementing E.O. 13771. The Regulatory Impact Analysis provides some
general information on the value of ecosystem services provided by
general categories of aquatic resources that may be impacted by
activities authorized by NWPs and thus result in some degree of loss of
ecosystem services. Other activities authorized by NWPs (e.g., aquatic
resource restoration and enhancement activities authorized by NWP 27
and the removal of low-head dams authorized by NWP 53) are generally
expected to result in gains in some ecosystem services. Any
consideration of ecosystem services lost as a result of activities
authorized by NWPs must also take into account any gains in goods and
services provided by activities authorized by NWPs or the operation of
those activities, such as housing, food production, energy generation
and transmission, transportation, public safety, providing potable
water, removing sewage, etc. In the Regulatory Impact Analysis for this
final rule, the Corps has added a general discussion of the goods and
services that activities authorized by the NWPs provide for human well-
being.
Increases in downstream flooding are usually caused by development
activities (e.g., the construction of houses, commercial buildings,
[[Page 2856]]
educational buildings, manufacturing buildings, roads, parking lots,
etc.) that reduce the land area in a watershed where precipitation can
infiltrate into the soil, and subsequently cause increases in surface
runoff to downstream waters that increase the frequency and severity of
flooding (NRC 2009). Upland development activities provide a
significant contribution to these changes in watershed hydrology,
because wetlands and streams occupy a relatively small percentage of
land area in a watershed (e.g., Zedler and Kercher et al. 2005, Butman
and Raymond 2011). State and local government agencies may require
developers to construct stormwater management facilities and green
infrastructure (e.g., rain gardens) to provide water storage and water
infiltration within the watershed to reduce potential changes in
downstream flooding.
Stream compensatory mitigation was added to the mitigation general
condition for the NWPs in 2007 (see general condition 20 in the 2007
NWP final rule at 72 FR 11193). That general condition did not have an
acreage-based or linear foot based threshold for stream mitigation. In
the 2012 and 2017 final rules for the issuance and reissuance of the
NWPs (77 FR 10184 and 82 FR 1860, respectively), there was no acreage-
based or linear foot based threshold for stream mitigation. Under the
2007, 2012, and 2017 NWPs, district engineers determined on a case-by-
case basis whether stream compensatory mitigation is required for an
NWP activity. The 2020 Proposal is the first time the Corps proposed a
threshold in the mitigation general condition for the NWPs for stream
compensatory mitigation. In response to comments received on the 2020
Proposal, the Corps changed the proposed \1/10\-acre stream mitigation
threshold to \3/100\-acre to be consistent with the current practices
of numerous Corps districts for when they require stream compensatory
mitigation for proposed NWP activities. Therefore, the changes to
general condition 23 are not expected to reduce stream compensatory
mitigation for NWP or have substantive economic impacts on the
compensatory mitigation industry.
The removal of the PCN threshold in the 2017 NWP 12 for mechanized
land clearing of a forested wetland in a utility line right-of-way will
not eliminate compensatory mitigation requirements for those
activities. If the impacts to forested wetlands caused by mechanized
land clearing for an oil or natural gas pipeline right-of-way cannot be
restored to pre-construction contours in waters of the United States,
and there is a loss of greater than \1/10\-acre of forested wetlands,
then the project proponent is required to submit a PCN to the district
engineer. The district engineer may require compensatory mitigation to
offset those losses of waters of the United States. The district
engineer may also require compensatory mitigation to offset losses of
specific wetland functions (see paragraph (i) of general condition 23).
The Corps does not believe it is necessary to prepare a cost-
benefit analysis for reissuing the NWPs earlier than many of the users
of the NWPs expected. One of the reasons the Corps is conducting this
rulemaking is to address recent court decisions.
V. Administrative Requirements
Plain Language
In compliance with the principles in the President's Memorandum of
June 1, 1998, (63 FR 31885, June 10, 1998) regarding plain language,
this preamble is written using plain language. In writing this final
rule, the Corps used the active voice, short sentences, and common
everyday terms except for necessary technical terms.
Paperwork Reduction Act
The paperwork burden associated with the NWP relates exclusively to
the preparation of the PCN. While different NWPs require that different
information be included in a PCN, the Corps estimates that a PCN takes,
on average, 11 hours to complete. The 16 final NWPs would decrease the
total paperwork burden associated with this program because the Corps
estimates that under this final rule 59 more PCNs would be required
each year. This increase is due to the number of activities that would
be authorized under the 16 NWPs that previously required individual
permits, and the changes in the PCN thresholds for NWP 48 for
commercial shellfish mariculture activities and the modified PCN
thresholds for NWP 12 (oil and natural gas pipeline activities). The
paperwork burden associated with the 16 final NWPs is expected to
increase by approximately 99 hours per year from 160,677 hours to
160,776 hours.
The following table summarizes the projected changes in paperwork
burden from the 2017 NWPs to the 16 NWPs issued in this final rule.

An agency may not conduct or sponsor, and a person is not required
to respond to, a collection of information unless it displays a
currently valid Office of Management and Budget (OMB) control number.
For the Corps Regulatory Program under section 10 of the Rivers and
Harbors Act of 1899, Section 404 of the Clean Water Act, and section
103 of the Marine Protection, Research and Sanctuaries Act of 1972, the
current OMB approval number for information collection requirements is
maintained by the Corps of Engineers (OMB approval number 0710-0003).
Executive Order 12866
This action is a significant regulatory action under Executive
Order 12866 (58 FR 51735, October 4, 1993) that was submitted to the
Office of Management and Budget (OMB) for review.
Executive Order 13771
This final rule is considered an E.O. 13771 deregulatory action.
Details on the estimated cost savings can be found in the rule's
economic analysis.
Executive Order 13132
Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August
10, 1999), requires the Corps to develop an accountable process to
ensure ``meaningful and timely input by State and local officials in
the development of regulatory policies that have federalism
implications.'' The issuance and modification of NWPs does not have
federalism implications. The Corps does
[[Page 2857]]
not believe that the final NWPs will have substantial direct effects on
the states, on the relationship between the federal government and the
states, or on the distribution of power and responsibilities among the
various levels of government. These NWPs will not impose any additional
substantive obligations on state or local governments. Therefore,
Executive Order 13132 does not apply to this proposal.
Regulatory Flexibility Act, as Amended by the Small Business Regulatory
Enforcement Fairness Act of 1996, 5 U.S.C. 601 et seq.
The Regulatory Flexibility Act generally requires an agency to
prepare a regulatory flexibility analysis of any rule subject to
notice-and-comment rulemaking requirements under the Administrative
Procedure Act or any other statute unless the agency certifies that the
proposed rule will not have a significant economic impact on a
substantial number of small entities. Small entities include small
businesses, small organizations, and small governmental jurisdictions.
For purposes of assessing the impacts of the issuance and
modification of NWPs on small entities, a small entity is defined as:
(1) A small business based on Small Business Administration size
standards; (2) a small governmental jurisdiction that is a government
of a city, county, town, school district, or special district with a
population of less than 50,000; or (3) a small organization that is any
not-for-profit enterprise which is independently owned and operated and
is not dominant in its field.
The statues under which the Corps issues, reissues, or modifies
NWPs are Section 404(e) of the Clean Water Act (33 U.S.C. 1344(e)) and
section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. 403). Under
section 404, Department of the Army (DA) permits are required for
discharges of dredged or fill material into waters of the United
States. Under section 10, DA permits are required for any structures or
other work that affect the course, location, or condition of navigable
waters of the United States. Small entities proposing to discharge
dredged or fill material into waters of the United States and/or
install structures or conduct work in navigable waters of the United
States must obtain DA permits to conduct those activities, unless a
particular activity is exempt from those permit requirements.
Individual permits and general permits can be issued by the Corps to
satisfy the permit requirements of these two statutes. Nationwide
permits are a form of general permit issued by the Chief of Engineers.
Nationwide permits automatically expire and become null and void if
they are not modified or reissued within five years of their effective
date (see 33 CFR 330.6(b)). Furthermore, section 404(e) of the Clean
Water Act states that general permits, including NWPs, can be issued
for no more than five years. If the 2017 NWPs are not modified or
reissued, they will expire on March 18, 2022, and small entities and
other project proponents would be required to obtain alternative forms
of DA permits (i.e., standard permits, letters of permission, or
regional general permits) for activities involving discharges of
dredged or fill material into waters of the United States or structures
or work in navigable waters of the United States. Regional general
permits that authorize similar activities as the NWPs may be available
in some geographic areas, but small entities conducting regulated
activities outside those geographic areas would have to obtain
individual permits for activities that require DA permits.
When compared with the compliance costs for individual permits,
most of the terms and conditions of the NWPs are expected to result in
decreases in the costs of complying with the permit requirements of
sections 10 and 404. The anticipated decrease in compliance cost
results from the lower cost of obtaining NWP authorization instead of
standard permits. Unlike standard permits, NWPs authorize activities
without the requirement for public notice and comment on each proposed
activity.
Another requirement of section 404(e) of the Clean Water Act is
that general permits, including NWPs, authorize only those activities
that result in no more than minimal adverse environmental effects,
individually and cumulatively. The terms and conditions of the NWPs,
such as acreage limits and the mitigation measures in some of the NWP
general conditions, are imposed to ensure that the NWPs authorize only
those activities that result in no more than minimal adverse effects on
the aquatic environment and other public interest review factors.
After considering the economic impacts of the NWPs on small
entities, I certify that this action will not have a significant impact
on a substantial number of small entities. Small entities may obtain
required DA authorizations through the NWPs, in cases where there are
applicable NWPs authorizing those activities and the proposed work will
result in only minimal adverse effects on the aquatic environment and
other public interest review factors. The terms and conditions of the
revised NWPs will not impose substantially higher costs on small
entities than those of the existing NWPs. If an NWP is not available to
authorize a particular activity, then another form of DA authorization,
such as an individual permit or a regional general permit
authorization, must be secured. However, as noted above, the Corps
estimates an increase in the number of activities than can be
authorized through NWPs, because the Corps made some modifications to
the NWPs to authorize additional activities. Because those activities
required authorization through other forms of DA authorization (e.g.,
individual permits or regional general permits) the Corps expects a
concurrent decrease in the numbers of individual permit and regional
general permit authorizations required for these activities.
Unfunded Mandates Reform Act
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public
Law 104-4, establishes requirements for federal agencies to assess the
effects of their regulatory actions on state, local, and tribal
governments and the private sector. Under section 202 of the UMRA, the
agencies generally must prepare a written statement, including a cost-
benefit analysis, for proposed and final rules with ``federal
mandates'' that may result in expenditures to state, local, and tribal
governments, in the aggregate, or to the private sector, of $100
million or more in any one year. Before promulgating a rule for which a
written statement is needed, section 205 of the UMRA generally requires
the agencies to identify and consider a reasonable number of regulatory
alternatives and adopt the least costly, most cost-effective, or least
burdensome alternative that achieves the objectives of the rule. The
provisions of section 205 do not apply when they are inconsistent with
applicable law. Moreover, section 205 allows an agency to adopt an
alternative other than the least costly, most cost-effective, or least
burdensome alternative if the agency publishes with the final rule an
explanation why that alternative was not adopted. Before an agency
establishes any regulatory requirements that may significantly or
uniquely affect small governments, including tribal governments, it
must have developed, under section 203 of the UMRA, a small government
agency plan. The plan must provide for notifying potentially affected
small governments, enabling officials of affected small governments to
have meaningful and timely input in the development of regulatory
proposals with significant federal
[[Page 2858]]
intergovernmental mandates, and informing, educating, and advising
small governments on compliance with the regulatory requirements.
The Corps has determined that the NWPs do not contain a federal
mandate that may result in expenditures of $100 million or more for
state, local, and tribal governments, in the aggregate, or the private
sector in any one year. The NWPs are generally consistent with current
agency practice, do not impose new substantive requirements and
therefore do not contain a federal mandate that may result in
expenditures of $100 million or more for state, local, and tribal
governments, in the aggregate, or the private sector in any one year.
Therefore, this final rule is not subject to the requirements of
sections 202 and 205 of the UMRA. For the same reasons, the Corps has
determined that the NWPs contain no regulatory requirements that might
significantly or uniquely affect small governments. Therefore, the
issuance and modification of NWPs is not subject to the requirements of
section 203 of UMRA.
Executive Order 13045
Executive Order 13045, ``Protection of Children from Environmental
Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997), applies
to any rule that: (1) Is determined to be ``economically significant''
as defined under Executive Order 12866, and (2) concerns an
environmental health or safety risk that we have reason to believe may
have a disproportionate effect on children. If the regulatory action
meets both criteria, we must evaluate the environmental health or
safety effects of the proposed rule on children and explain why the
regulation is preferable to other potentially effective and reasonably
feasible alternatives.
The NWPs are not subject to this Executive Order because they are
not economically significant as defined in Executive Order 12866. In
addition, the proposed NWPs do not concern an environmental health or
safety risk that the Corps has reason to believe may have a
disproportionate effect on children.
Executive Order 13175
Executive Order 13175, entitled ``Consultation and Coordination
with Indian Tribal Governments'' (65 FR 67249, November 6, 2000),
requires agencies to develop an accountable process to ensure
``meaningful and timely input by tribal officials in the development of
regulatory policies that have tribal implications.'' The phrase
``policies that have tribal implications'' is defined in the Executive
Order to include regulations that have ``substantial direct effects on
one or more Tribes, on the relationship between the federal government
and the Tribes, or on the distribution of power and responsibilities
between the federal government and Tribes.''
The issuance of these NWPs is generally consistent with current
agency practice and will not have substantial direct effects on tribal
governments, on the relationship between the federal government and the
tribes, or on the distribution of power and responsibilities between
the federal government and tribes. Therefore, Executive Order 13175
does not apply to this final rule. However, in the spirit of Executive
Order 13175, the Corps specifically requested comments from tribal
officials on the proposed rule. Their comments were fully considered
during the preparation of this final rule. Each Corps district
conducted government-to-government consultation with tribes, to
identify regional conditions, other local NWP modifications to protect
aquatic resources of interest to tribes, and coordination procedures
with tribes, as part of the Corps' responsibility to protect tribal
trust resources and fulfill its tribal trust responsibilities.
Many commenters stated that they disagreed with the Corps'
determination that the proposal to reissue and issue the NWPs would not
have substantial direct effects on tribal governments, on the
relationship between the federal government and the tribes, or on the
distribution of power and responsibilities between the federal
government and tribes. Most of these commenters said that the Corps is
required to consult and coordinate with the tribes on the proposed
rule. Many commenters stated that meaningful consultation with tribes
is not possible given the short time frames set by the administration,
lack of information, and complications resulting from the COVID
pandemic. One commenter stated that the Corps should extend its comment
period 60 days or should withdraw its proposal to allow early tribal
engagement.
While the NWPs are regulations, the Corps believe the final NWPs
will not have substantial direct effects on tribal governments, on the
relationship between the federal government and the tribes, or on the
distribution of power and responsibilities between the federal
government and tribes. In response to the proposed rule, the Corps
received comments from 35 tribes and tribal organizations. The Corps
has taken, and will continue to take, measures (such as Corps districts
consulting with tribes on specific NWP activities that may have adverse
effects on tribal rights and tribal trust resources) to ensure that the
NWPs will not have substantial direct effects on tribal governments, on
the relationship between the federal government and the tribes, or on
the distribution of power and responsibilities between the federal
government and tribes. General condition 17 has been modified to state
that no NWP activity or its operation may impair reserved tribal
rights, including, but not limited to, reserved water rights and treaty
fishing and hunting rights. Tribes use NWPs for activities they conduct
that require DA authorization under section 404 of the Clean Water Act
and/or section 10 of the Rivers and Harbors Act of 1899. For example,
tribes that conduct commercial shellfish mariculture activities have
used NWP 48, and tribes that conduct aquatic habitat restoration
activities have used NWP 27.
For 16 NWPs issued in this final rule, Corps districts conducted
consultations with tribes to identify regional conditions to ensure
that NWP activities comply with general conditions 17 and 20. Through
those consultations, district engineers can also develop coordination
procedures with tribes to provide tribes with opportunities to review
proposed NWP activities and provide their views on whether those
activities will cause more than minimal adverse effects on tribal
rights (including treaty rights), protected tribal resources, or tribal
lands. When a Corps district receives a pre-construction notification
that triggers a need to consult with one or more tribes, that
consultation will be completed before the district engineer makes his
or her decision on whether to issue the NWP verification. If, after
considering mitigation, the district engineer determines the proposed
NWP activity will have more than minimal adverse effects on tribal
rights (including treaty rights), protected tribal resources, or tribal
lands, he or she will exercise discretionary authority and require an
individual permit. Division engineers can modify, suspend, or revoke
one or more NWPs in a region to protect tribal rights. A district
engineer can modify, suspend, or revoke an NWP to protect tribal
rights, protected tribal resources, and tribal lands.
For the 2020 Proposal, the Corps provided a 60-day public comment
period, which is consistent with the length of the comment period
provided for past NWP rulemaking efforts. After the comment period for
the 2020 Proposal ended on November 16, 2020, there was some additional
time for Corps districts to conduct consultation
[[Page 2859]]
and coordination with tribes. For Corps district consultation and
coordination with tribes, the Corps provided information similar to the
information provided during past NWP rulemaking efforts. The Corps
acknowledges that the pandemic complicated tribal consultation and
coordination activities, but the rulemaking effort needed to be
completed by the required time frame.
Environmental Documentation
A decision document has been prepared for each of the 16 NWPs being
issued in this final rule. Each decision document includes an
environmental assessment and public interest review determination. If
an NWP authorizes discharges of dredged or fill material into waters of
the United States, the decision document includes a 404(b)(1)
Guidelines analysis. These decision documents are available at:
www.regulations.gov (docket ID number COE-2020-0002). They are also
available by contacting Headquarters, U.S. Army Corps of Engineers,
Operations and Regulatory Community of Practice, 441 G Street NW,
Washington, DC 20314-1000.
Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. The Corps will submit a report containing the final 16
NWPs and other required information to the U.S. Senate, the U.S. House
of Representatives, and the Government Accountability Office. A major
rule cannot take effect until 60 days after it is published in the
Federal Register. The 16 NWPs are not a ``major rule'' as defined by 5
U.S.C. 804(2), because they are not likely to result in: (1) An annual
effect on the economy of $100,000,000 or more; (2) a major increase in
costs or prices for consumers, individual industries, federal, state,
or local government agencies, or geographic regions; or (3) significant
adverse effects on competition, employment, investment, productivity,
innovation, or on the ability of United States-based enterprises to
compete with foreign-based enterprises in domestic and export markets.
Executive Order 12898
Executive Order 12898 requires that, to the greatest extent
practicable and permitted by law, each federal agency must make
achieving environmental justice part of its mission. Executive Order
12898 provides that each federal agency conduct its programs, policies,
and activities that substantially affect human health or the
environment in a manner that ensures that such programs, policies, and
activities do not have the effect of excluding persons (including
populations) from participation in, denying persons (including
populations) the benefits of, or subjecting persons (including
populations) to discrimination under such programs, policies, and
activities because of their race, color, or national origin.
The NWPs are not expected to have any discriminatory effect or
disproportionate negative impact on any community or group, and
therefore are not expected to cause any disproportionately high and
adverse impacts to minority or low-income communities.
Executive Order 13211
This action is not a ``significant energy action'' because it is
not likely to have a significant adverse effect on the supply,
distribution or use of energy and has not otherwise been designated by
the OIRA Administrator as a significant energy action.

12. Oil or Natural Gas Pipeline Activities. Activities required for
the construction, maintenance, repair, and removal of oil and natural
gas pipelines and associated facilities in waters of the United States,
provided the activity does not result in the loss of greater than \1/
2\-acre of waters of the United States for each single and complete
project.
Oil or natural gas pipelines: This NWP authorizes discharges of
dredged or fill material into waters of the United States and
structures or work in navigable waters for crossings of those waters
associated with the construction, maintenance, or repair of oil and
natural gas pipelines. There must be no change in pre-construction
contours of waters of the United States. An ``oil or natural gas
pipeline'' is defined as any pipe or pipeline for the transportation of
any form of oil or natural gas, including products derived from oil or
natural gas, such as gasoline, jet fuel, diesel fuel. heating oil,
petrochemical feedstocks, waxes, lubricating oils, and asphalt.
Material resulting from trench excavation may be temporarily
sidecast into waters of the United States for no more than three
months, provided the material is not placed in such a manner that it is
dispersed by currents or other forces. The district engineer may extend
the period of temporary side casting for no more than a total of 180
days, where appropriate. In wetlands, the top 6 to 12 inches of the
trench should normally be backfilled with topsoil from the trench. The
trench cannot be constructed or backfilled in such a manner as to drain
waters of the United States (e.g., backfilling with extensive gravel
layers, creating a french drain effect). Any exposed slopes and stream
banks must be stabilized immediately upon completion of the utility
line crossing of each waterbody.
Oil or natural gas pipeline substations: This NWP authorizes the
construction, maintenance, or expansion of substation facilities (e.g.,
oil or natural gas or gaseous fuel custody transfer stations, boosting
stations, compression stations, metering stations, pressure regulating
stations) associated with an oil or natural gas pipeline in non-tidal
waters of the United States, provided the activity, in combination with
all other activities included in one single and complete project, does
not result in the loss of greater than \1/2\-acre of waters of the
United States. This NWP does not authorize discharges of dredged or
fill material into non-tidal wetlands adjacent to tidal waters of the
United States to construct, maintain, or expand substation facilities.
Foundations for above-ground oil or natural gas pipelines: This NWP
authorizes the construction or maintenance of foundations for above-
ground oil or natural gas pipelines in all waters of the United States,
provided the foundations are the minimum size necessary.
Access roads: This NWP authorizes the construction of access roads
for the construction and maintenance of oil or natural gas pipelines,
in non-tidal waters of the United States, provided the activity, in
combination with all other activities included in one single and
complete project, does not cause the loss of greater than \1/2\-acre of
non-tidal waters of the United States. This NWP does not authorize
discharges of dredged or fill material into non-tidal wetlands adjacent
to tidal waters for access roads. Access roads must be the minimum
width necessary (see Note 2, below). Access roads must be constructed
so that the length of the road minimizes any adverse effects on waters
of the United States and must be as near as possible to pre-
construction contours and elevations (e.g., at grade corduroy roads or
geotextile/gravel roads). Access roads constructed above pre-
construction contours and elevations in waters of the United States
must be properly bridged or culverted to maintain surface flows.
This NWP may authorize oil or natural gas pipelines in or affecting
navigable waters of the United States even if there is no associated
discharge of dredged or fill material (see 33 CFR part 322). Oil or
natural gas pipelines routed in, over, or under section 10 waters
without a discharge of dredged or fill material may require a section
10 permit.
This NWP authorizes, to the extent that Department of the Army
authorization is required, temporary structures, fills, and work
necessary for the remediation of inadvertent returns of drilling fluids
to waters of the United States through sub-soil fissures or fractures
that might occur during horizontal directional drilling activities
conducted for the purpose of installing or replacing oil or natural gas
pipelines. These remediation activities must be done as soon as
practicable, to restore the affected waterbody. District engineers may
add special conditions to this NWP to require a remediation plan for
addressing inadvertent returns of drilling fluids to waters of the
United States during horizontal directional drilling activities
conducted for the purpose of installing or replacing oil or natural gas
pipelines.
This NWP also authorizes temporary structures, fills, and work,
including the use of temporary mats, necessary to conduct the oil or
natural gas pipeline activity. Appropriate measures must be taken to
maintain normal downstream flows and minimize flooding to the maximum
extent practicable, when temporary structures, work, and discharges of
dredged or fill material, including cofferdams, are necessary for
construction activities, access fills, or dewatering of construction
sites. Temporary fills must consist of materials, and be placed in a
manner, that will not be eroded by expected high flows. After
construction, temporary fills must be removed in their entirety and the
affected areas returned to pre-construction elevations. The areas
affected by temporary fills must be revegetated, as appropriate.
Notification: The permittee must submit a pre-construction
notification to the district engineer prior to commencing the activity
if: (1) A section 10 permit is required; (2) the discharge will result
in the loss of greater than \1/10\-acre of waters of the United States;
or (3) the proposed oil or natural gas pipeline activity is associated
with an overall project that is greater than 250 miles in length and
the project purpose is to install new pipeline (vs. conduct repair or
maintenance activities) along the majority of the distance of the
overall project length. If the proposed oil or gas pipeline is greater
than 250 miles in length, the pre-construction
[[Page 2861]]
notification must include the locations and proposed impacts (in acres
or other appropriate unit of measure) for all crossings of waters of
the United States that require DA authorization, including those
crossings authorized by an NWP would not otherwise require pre-
construction notification. (See general condition 32.) (Authorities:
Sections 10 and 404)
Note 1: Where the oil or natural gas pipeline is constructed,
installed, or maintained in navigable waters of the United States
(i.e., section 10 waters) within the coastal United States, the Great
Lakes, and United States territories, a copy of the NWP verification
will be sent by the Corps to the National Oceanic and Atmospheric
Administration (NOAA), National Ocean Service (NOS), for charting the
oil or natural gas pipeline to protect navigation.
Note 2: For oil or natural gas pipeline activities crossing a
single waterbody more than one time at separate and distant locations,
or multiple waterbodies at separate and distant locations, each
crossing is considered a single and complete project for purposes of
NWP authorization. Oil or natural gas pipeline activities must comply
with 33 CFR 330.6(d).
Note 3: Access roads used for both construction and maintenance may
be authorized, provided they meet the terms and conditions of this NWP.
Access roads used solely for construction of the oil or natural gas
pipeline must be removed upon completion of the work, in accordance
with the requirements for temporary fills.
Note 4: Pipes or pipelines used to transport gaseous, liquid,
liquescent, or slurry substances over navigable waters of the United
States are considered to be bridges, and may require a permit from the
U.S. Coast Guard pursuant to the General Bridge Act of 1946. However,
any discharges of dredged or fill material into waters of the United
States associated with such oil or natural gas pipelines will require a
section 404 permit (see NWP 15).
Note 5: This NWP authorizes oil or natural gas pipeline maintenance
and repair activities that do not qualify for the Clean Water Act
section 404(f) exemption for maintenance of currently serviceable fills
or fill structures.
Note 6: For NWP 12 activities that require pre-construction
notification, the PCN must include any other NWP(s), regional general
permit(s), or individual permit(s) used or intended to be used to
authorize any part of the proposed project or any related activity,
including other separate and distant crossings that require Department
of the Army authorization but do not require pre-construction
notification (see paragraph (b)(4) of general condition 32). The
district engineer will evaluate the PCN in accordance with Section D,
``District Engineer's Decision.'' The district engineer may require
mitigation to ensure that the authorized activity results in no more
than minimal individual and cumulative adverse environmental effects
(see general condition 23).

States. An ``electric utility line and telecommunication line'' is
defined as any cable, line, fiber optic line, or wire for the
transmission for any purpose of electrical energy, telephone, and
telegraph messages, and internet, radio, and television communication.
Material resulting from trench excavation may be temporarily
sidecast into waters of the United States for no more than three
months, provided the material is not placed in such a manner that it is
dispersed by currents or other forces. The district engineer may extend
the period of temporary side casting for no more than a total of 180
days, where appropriate. In wetlands, the top 6 to 12 inches of the
trench should normally be backfilled with topsoil from the trench. The
trench cannot be constructed or backfilled in such a manner as to drain
waters of the United States (e.g., backfilling with extensive gravel
layers, creating a french drain effect). Any exposed slopes and stream
banks must be stabilized immediately upon completion of the electric
utility line or telecommunication line crossing of each waterbody.
Electric utility line and telecommunications substations: This NWP
authorizes the construction, maintenance, or expansion of substation
facilities associated with an electric utility line or
telecommunication line in non-tidal waters of the United States,
provided the activity, in combination with all other activities
included in one single and complete project, does not result in the
loss of greater than \1/2\-acre of waters of the United States. This
NWP does not authorize discharges of dredged or fill material into non-
tidal wetlands adjacent to tidal waters of the United States to
construct, maintain, or expand substation facilities.
Foundations for overhead electric utility line or telecommunication
line towers, poles, and anchors: This NWP authorizes the construction
or maintenance of foundations for overhead electric utility line or
telecommunication line towers, poles, and anchors in all waters of the
United States, provided the foundations are the minimum size necessary
and separate footings for each tower leg (rather than a larger single
pad) are used where feasible.
Access roads: This NWP authorizes the construction of access roads
for the construction and maintenance of electric utility lines or
telecommunication lines, including overhead lines and substations, in
non-tidal waters of the United States, provided the activity, in
combination with all other activities included in one single and
complete project, does not cause the loss of greater than \1/2\-acre of
non-tidal waters of the United States. This NWP does not authorize
discharges of dredged or fill material into non-tidal wetlands adjacent
to tidal waters for access roads. Access roads must be the minimum
width necessary (see Note 2, below). Access roads must be constructed
so that the length of the road minimizes any adverse effects on waters
of the United States and must be as near as possible to pre-
construction contours and elevations (e.g., at grade corduroy roads or
geotextile/gravel roads). Access roads constructed above pre-
construction contours and elevations in waters of the United States
must be properly bridged or culverted to maintain surface flows.
This NWP may authorize electric utility lines or telecommunication
lines in or affecting navigable waters of the United States even if
there is no associated discharge of dredged or fill material (see 33
CFR part 322). Electric utility lines or telecommunication lines
constructed over section 10 waters and electric utility lines or
telecommunication lines that are routed in or under section 10 waters
without a discharge of dredged or fill material require a section 10
permit.
[[Page 2866]]
This NWP authorizes, to the extent that Department of the Army
authorization is required, temporary structures, fills, and work
necessary for the remediation of inadvertent returns of drilling fluids
to waters of the United States through sub-soil fissures or fractures
that might occur during horizontal directional drilling activities
conducted for the purpose of installing or replacing electric utility
lines or telecommunication lines. These remediation activities must be
done as soon as practicable, to restore the affected waterbody.
District engineers may add special conditions to this NWP to require a
remediation plan for addressing inadvertent returns of drilling fluids
to waters of the United States during horizontal directional drilling
activities conducted for the purpose of installing or replacing
electric utility lines or telecommunication lines.
This NWP also authorizes temporary structures, fills, and work,
including the use of temporary mats, necessary to conduct the electric
utility line activity. Appropriate measures must be taken to maintain
normal downstream flows and minimize flooding to the maximum extent
practicable, when temporary structures, work, and discharges of dredged
or fill material, including cofferdams, are necessary for construction
activities, access fills, or dewatering of construction sites.
Temporary fills must consist of materials, and be placed in a manner,
that will not be eroded by expected high flows. After construction,
temporary fills must be removed in their entirety and the affected
areas returned to pre-construction elevations. The areas affected by
temporary fills must be revegetated, as appropriate.
Notification: The permittee must submit a pre-construction
notification to the district engineer prior to commencing the activity
if: (1) A section 10 permit is required; or (2) the discharge will
result in the loss of greater than \1/10\-acre of waters of the United
States. (See general condition 32.) (Authorities: Sections 10 and 404)
Note 1: Where the electric utility line is constructed, installed,
or maintained in navigable waters of the United States (i.e., section
10 waters) within the coastal United States, the Great Lakes, and
United States territories, a copy of the NWP verification will be sent
by the Corps to the National Oceanic and Atmospheric Administration
(NOAA), National Ocean Service (NOS), for charting the electric utility
line to protect navigation.
Note 2: For electric utility line or telecommunications activities
crossing a single waterbody more than one time at separate and distant
locations, or multiple waterbodies at separate and distant locations,
each crossing is considered a single and complete project for purposes
of NWP authorization. Electric utility line and telecommunications
activities must comply with 33 CFR 330.6(d).
Note 3: Electric utility lines or telecommunication lines
consisting of aerial electric power transmission lines crossing
navigable waters of the United States (which are defined at 33 CFR part
329) must comply with the applicable minimum clearances specified in 33
CFR 322.5(i).
Note 4: Access roads used for both construction and maintenance may
be authorized, provided they meet the terms and conditions of this NWP.
Access roads used solely for construction of the electric utility line
or telecommunication line must be removed upon completion of the work,
in accordance with the requirements for temporary fills.
Note 5: This NWP authorizes electric utility line and
telecommunication line maintenance and repair activities that do not
qualify for the Clean Water Act section 404(f) exemption for
maintenance of currently serviceable fills or fill structures.
Note 6: For overhead electric utility lines and telecommunication
lines authorized by this NWP, a copy of the PCN and NWP verification
will be provided by the Corps to the Department of Defense Siting
Clearinghouse, which will evaluate potential effects on military
activities.
Note 7: For activities that require pre-construction notification,
the PCN must include any other NWP(s), regional general permit(s), or
individual permit(s) used or intended to be used to authorize any part
of the proposed project or any related activity, including other
separate and distant crossings that require Department of the Army
authorization but do not require pre-construction notification (see
paragraph (b)(4) of general condition 32). The district engineer will
evaluate the PCN in accordance with Section D, ``District Engineer's
Decision.'' The district engineer may require mitigation to ensure that
the authorized activity results in no more than minimal individual and
cumulative adverse environmental effects (see general condition 23).
58. Utility Line Activities for Water and Other Substances.
Activities required for the construction, maintenance, repair, and
removal of utility lines for water and other substances, excluding oil,
natural gas, products derived from oil or natural gas, and electricity.
Oil or natural gas pipeline activities or electric utility line and
telecommunications activities may be authorized by NWPs 12 or 57,
respectively. This NWP also authorizes associated utility line
facilities in waters of the United States, provided the activity does
not result in the loss of greater than \1/2\-acre of waters of the
United States for each single and complete project.
Utility lines: This NWP authorizes discharges of dredged or fill
material into waters of the United States and structures or work in
navigable waters for crossings of those waters associated with the
construction, maintenance, or repair of utility lines for water and
other substances, including outfall and intake structures. There must
be no change in pre-construction contours of waters of the United
States. A ``utility line'' is defined as any pipe or pipeline for the
transportation of any gaseous, liquid, liquescent, or slurry substance,
for any purpose that is not oil, natural gas, or petrochemicals.
Examples of activities authorized by this NWP include utility lines
that convey water, sewage, stormwater, wastewater, brine, irrigation
water, and industrial products that are not petrochemicals. The term
``utility line'' does not include activities that drain a water of the
United States, such as drainage tile or french drains, but it does
apply to pipes conveying drainage from another area.
Material resulting from trench excavation may be temporarily
sidecast into waters of the United States for no more than three
months, provided the material is not placed in such a manner that it is
dispersed by currents or other forces. The district engineer may extend
the period of temporary side casting for no more than a total of 180
days, where appropriate. In wetlands, the top 6 to 12 inches of the
trench should normally be backfilled with topsoil from the trench. The
trench cannot be constructed or backfilled in such a manner as to drain
waters of the United States (e.g., backfilling with extensive gravel
layers, creating a french drain effect). Any exposed slopes and stream
banks must be stabilized immediately upon completion of the utility
line crossing of each waterbody.
Utility line substations: This NWP authorizes the construction,
maintenance, or expansion of substation facilities associated with a
utility line in non-tidal waters of the United States, provided the
activity, in combination with all other activities included in one
single and complete project, does not result in the loss of greater
than \1/2\-acre of waters of the United States. This
[[Page 2867]]
NWP does not authorize discharges of dredged or fill material into non-
tidal wetlands adjacent to tidal waters of the United States to
construct, maintain, or expand substation facilities.
Foundations for above-ground utility lines: This NWP authorizes the
construction or maintenance of foundations for above-ground utility
lines in all waters of the United States, provided the foundations are
the minimum size necessary.
Access roads: This NWP authorizes the construction of access roads
for the construction and maintenance of utility lines, including
utility line substations, in non-tidal waters of the United States,
provided the activity, in combination with all other activities
included in one single and complete project, does not cause the loss of
greater than \1/2\-acre of non-tidal waters of the United States. This
NWP does not authorize discharges of dredged or fill material into non-
tidal wetlands adjacent to tidal waters for access roads. Access roads
must be the minimum width necessary (see Note 2, below). Access roads
must be constructed so that the length of the road minimizes any
adverse effects on waters of the United States and must be as near as
possible to pre-construction contours and elevations (e.g., at grade
corduroy roads or geotextile/gravel roads). Access roads constructed
above pre-construction contours and elevations in waters of the United
States must be properly bridged or culverted to maintain surface flows.
This NWP may authorize utility lines in or affecting navigable
waters of the United States even if there is no associated discharge of
dredged or fill material (see 33 CFR part 322). Overhead utility lines
constructed over section 10 waters and utility lines that are routed in
or under section 10 waters without a discharge of dredged or fill
material require a section 10 permit.
This NWP authorizes, to the extent that Department of the Army
authorization is required, temporary structures, fills, and work
necessary for the remediation of inadvertent returns of drilling fluids
to waters of the United States through sub-soil fissures or fractures
that might occur during horizontal directional drilling activities
conducted for the purpose of installing or replacing utility lines.
These remediation activities must be done as soon as practicable, to
restore the affected waterbody. District engineers may add special
conditions to this NWP to require a remediation plan for addressing
inadvertent returns of drilling fluids to waters of the United States
during horizontal directional drilling activities conducted for the
purpose of installing or replacing utility lines.
This NWP also authorizes temporary structures, fills, and work,
including the use of temporary mats, necessary to conduct the utility
line activity. Appropriate measures must be taken to maintain normal
downstream flows and minimize flooding to the maximum extent
practicable, when temporary structures, work, and discharges of dredged
or fill material, including cofferdams, are necessary for construction
activities, access fills, or dewatering of construction sites.
Temporary fills must consist of materials, and be placed in a manner,
that will not be eroded by expected high flows. After construction,
temporary fills must be removed in their entirety and the affected
areas returned to pre-construction elevations. The areas affected by
temporary fills must be revegetated, as appropriate.
Notification: The permittee must submit a pre-construction
notification to the district engineer prior to commencing the activity
if: (1) A section 10 permit is required; or (2) the discharge will
result in the loss of greater than \1/10\-acre of waters of the United
States. (See general condition 32.) (Authorities: Sections 10 and 404)
Note 1: Where the utility line is constructed, installed, or
maintained in navigable waters of the United States (i.e., section 10
waters) within the coastal United States, the Great Lakes, and United
States territories, a copy of the NWP verification will be sent by the
Corps to the National Oceanic and Atmospheric Administration (NOAA),
National Ocean Service (NOS), for charting the utility line to protect
navigation.
Note 2: For utility line activities crossing a single waterbody
more than one time at separate and distant locations, or multiple
waterbodies at separate and distant locations, each crossing is
considered a single and complete project for purposes of NWP
authorization. Utility line activities must comply with 33 CFR
330.6(d).
Note 3: Access roads used for both construction and maintenance may
be authorized, provided they meet the terms and conditions of this NWP.
Access roads used solely for construction of the utility line must be
removed upon completion of the work, in accordance with the
requirements for temporary fills.
Note 4: Pipes or pipelines used to transport gaseous, liquid,
liquescent, or slurry substances over navigable waters of the United
States are considered to be bridges, not utility lines, and may require
a permit from the U.S. Coast Guard pursuant to the General Bridge Act
of 1946. However, any discharges of dredged or fill material into
waters of the United States associated with such pipelines will require
a section 404 permit (see NWP 15).
Note 5: This NWP authorizes utility line maintenance and repair
activities that do not qualify for the Clean Water Act section 404(f)
exemption for maintenance of currently serviceable fills or fill
structures.
Note 6: For activities that require pre-construction notification,
the PCN must include any other NWP(s), regional general permit(s), or
individual permit(s) used or intended to be used to authorize any part
of the proposed project or any related activity, including other
separate and distant crossings that require Department of the Army
authorization but do not require pre-construction notification (see
paragraph (b)(4) of general condition 32). The district engineer will
evaluate the PCN in accordance with Section D, ``District Engineer's
Decision.'' The district engineer may require mitigation to ensure that
the authorized activity results in no more than minimal individual and
cumulative adverse environmental effects (see general condition 23).
C. Nationwide Permit General Conditions
Note: To qualify for NWP authorization, the prospective permittee
must comply with the following general conditions, as applicable, in
addition to any regional or case-specific conditions imposed by the
division engineer or district engineer. Prospective permittees should
contact the appropriate Corps district office to determine if regional
conditions have been imposed on an NWP. Prospective permittees should
also contact the appropriate Corps district office to determine the
status of Clean Water Act Section 401 water quality certification and/
or Coastal Zone Management Act consistency for an NWP. Every person who
may wish to obtain permit authorization under one or more NWPs, or who
is currently relying on an existing or prior permit authorization under
one or more NWPs, has been and is on notice that all of the provisions
of 33 CFR 330.1 through 330.6 apply to every NWP authorization. Note
especially 33 CFR 330.5 relating to the modification, suspension, or
revocation of any NWP authorization.
1. Navigation. (a) No activity may cause more than a minimal
adverse effect on navigation.
(b) Any safety lights and signals prescribed by the U.S. Coast
Guard,
[[Page 2868]]
through regulations or otherwise, must be installed and maintained at
the permittee's expense on authorized facilities in navigable waters of
the United States.
(c) The permittee understands and agrees that, if future operations
by the United States require the removal, relocation, or other
alteration, of the structure or work herein authorized, or if, in the
opinion of the Secretary of the Army or his or her authorized
representative, said structure or work shall cause unreasonable
obstruction to the free navigation of the navigable waters, the
permittee will be required, upon due notice from the Corps of
Engineers, to remove, relocate, or alter the structural work or
obstructions caused thereby, without expense to the United States. No
claim shall be made against the United States on account of any such
removal or alteration.
2. Aquatic Life Movements. No activity may substantially disrupt
the necessary life cycle movements of those species of aquatic life
indigenous to the waterbody, including those species that normally
migrate through the area, unless the activity's primary purpose is to
impound water. All permanent and temporary crossings of waterbodies
shall be suitably culverted, bridged, or otherwise designed and
constructed to maintain low flows to sustain the movement of those
aquatic species. If a bottomless culvert cannot be used, then the
crossing should be designed and constructed to minimize adverse effects
to aquatic life movements.
3. Spawning Areas. Activities in spawning areas during spawning
seasons must be avoided to the maximum extent practicable. Activities
that result in the physical destruction (e.g., through excavation,
fill, or downstream smothering by substantial turbidity) of an
important spawning area are not authorized.
4. Migratory Bird Breeding Areas. Activities in waters of the
United States that serve as breeding areas for migratory birds must be
avoided to the maximum extent practicable.
5. Shellfish Beds. No activity may occur in areas of concentrated
shellfish populations, unless the activity is directly related to a
shellfish harvesting activity authorized by NWPs 4 and 48, or is a
shellfish seeding or habitat restoration activity authorized by NWP 27.
6. Suitable Material. No activity may use unsuitable material
(e.g., trash, debris, car bodies, asphalt, etc.). Material used for
construction or discharged must be free from toxic pollutants in toxic
amounts (see section 307 of the Clean Water Act).
7. Water Supply Intakes. No activity may occur in the proximity of
a public water supply intake, except where the activity is for the
repair or improvement of public water supply intake structures or
adjacent bank stabilization.
8. Adverse Effects From Impoundments. If the activity creates an
impoundment of water, adverse effects to the aquatic system due to
accelerating the passage of water, and/or restricting its flow must be
minimized to the maximum extent practicable.
9. Management of Water Flows. To the maximum extent practicable,
the pre-construction course, condition, capacity, and location of open
waters must be maintained for each activity, including stream
channelization, storm water management activities, and temporary and
permanent road crossings, except as provided below. The activity must
be constructed to withstand expected high flows. The activity must not
restrict or impede the passage of normal or high flows, unless the
primary purpose of the activity is to impound water or manage high
flows. The activity may alter the pre-construction course, condition,
capacity, and location of open waters if it benefits the aquatic
environment (e.g., stream restoration or relocation activities).
10. Fills Within 100-Year Floodplains. The activity must comply
with applicable FEMA-approved state or local floodplain management
requirements.
11. Equipment. Heavy equipment working in wetlands or mudflats must
be placed on mats, or other measures must be taken to minimize soil
disturbance.
12. Soil Erosion and Sediment Controls. Appropriate soil erosion
and sediment controls must be used and maintained in effective
operating condition during construction, and all exposed soil and other
fills, as well as any work below the ordinary high water mark or high
tide line, must be permanently stabilized at the earliest practicable
date. Permittees are encouraged to perform work within waters of the
United States during periods of low-flow or no-flow, or during low
tides.
13. Removal of Temporary Structures and Fills. Temporary structures
must be removed, to the maximum extent practicable, after their use has
been discontinued. Temporary fills must be removed in their entirety
and the affected areas returned to pre-construction elevations. The
affected areas must be revegetated, as appropriate.
14. Proper Maintenance. Any authorized structure or fill shall be
properly maintained, including maintenance to ensure public safety and
compliance with applicable NWP general conditions, as well as any
activity-specific conditions added by the district engineer to an NWP
authorization.
15. Single and Complete Project. The activity must be a single and
complete project. The same NWP cannot be used more than once for the
same single and complete project.
16. Wild and Scenic Rivers. (a) No NWP activity may occur in a
component of the National Wild and Scenic River System, or in a river
officially designated by Congress as a ``study river'' for possible
inclusion in the system while the river is in an official study status,
unless the appropriate Federal agency with direct management
responsibility for such river, has determined in writing that the
proposed activity will not adversely affect the Wild and Scenic River
designation or study status.
(b) If a proposed NWP activity will occur in a component of the
National Wild and Scenic River System, or in a river officially
designated by Congress as a ``study river'' for possible inclusion in
the system while the river is in an official study status, the
permittee must submit a pre-construction notification (see general
condition 32). The district engineer will coordinate the PCN with the
Federal agency with direct management responsibility for that river.
Permittees shall not begin the NWP activity until notified by the
district engineer that the Federal agency with direct management
responsibility for that river has determined in writing that the
proposed NWP activity will not adversely affect the Wild and Scenic
River designation or study status.
(c) Information on Wild and Scenic Rivers may be obtained from the
appropriate Federal land management agency responsible for the
designated Wild and Scenic River or study river (e.g., National Park
Service, U.S. Forest Service, Bureau of Land Management, U.S. Fish and
Wildlife Service). Information on these rivers is also available at:
http://www.rivers.gov/.
17. Tribal Rights. No activity or its operation may impair reserved
tribal rights, including, but not limited to, reserved water rights and
treaty fishing and hunting rights.
18. Endangered Species. (a) No activity is authorized under any NWP
which is likely to directly or indirectly jeopardize the continued
existence of a threatened or endangered species or a species proposed
for such designation,
[[Page 2869]]
as identified under the Federal Endangered Species Act (ESA), or which
will directly or indirectly destroy or adversely modify designated
critical habitat or critical habitat proposed for such designation. No
activity is authorized under any NWP which ``may affect'' a listed
species or critical habitat, unless ESA section 7 consultation
addressing the consequences of the proposed activity on listed species
or critical habitat has been completed. See 50 CFR 402.02 for the
definition of ``effects of the action'' for the purposes of ESA section
7 consultation, as well as 50 CFR 402.17, which provides further
explanation under ESA section 7 regarding ``activities that are
reasonably certain to occur'' and ``consequences caused by the proposed
action.''
(b) Federal agencies should follow their own procedures for
complying with the requirements of the ESA (see 33 CFR 330.4(f)(1)). If
pre-construction notification is required for the proposed activity,
the Federal permittee must provide the district engineer with the
appropriate documentation to demonstrate compliance with those
requirements. The district engineer will verify that the appropriate
documentation has been submitted. If the appropriate documentation has
not been submitted, additional ESA section 7 consultation may be
necessary for the activity and the respective federal agency would be
responsible for fulfilling its obligation under section 7 of the ESA.
(c) Non-federal permittees must submit a pre-construction
notification to the district engineer if any listed species (or species
proposed for listing) or designated critical habitat (or critical
habitat proposed such designation) might be affected or is in the
vicinity of the activity, or if the activity is located in designated
critical habitat or critical habitat proposed for such designation, and
shall not begin work on the activity until notified by the district
engineer that the requirements of the ESA have been satisfied and that
the activity is authorized. For activities that might affect Federally-
listed endangered or threatened species (or species proposed for
listing) or designated critical habitat (or critical habitat proposed
for such designation), the pre-construction notification must include
the name(s) of the endangered or threatened species (or species
proposed for listing) that might be affected by the proposed activity
or that utilize the designated critical habitat (or critical habitat
proposed for such designation) that might be affected by the proposed
activity. The district engineer will determine whether the proposed
activity ``may affect'' or will have ``no effect'' to listed species
and designated critical habitat and will notify the non-Federal
applicant of the Corps' determination within 45 days of receipt of a
complete pre-construction notification. For activities where the non-
Federal applicant has identified listed species (or species proposed
for listing) or designated critical habitat (or critical habitat
proposed for such designation) that might be affected or is in the
vicinity of the activity, and has so notified the Corps, the applicant
shall not begin work until the Corps has provided notification that the
proposed activity will have ``no effect'' on listed species (or species
proposed for listing or designated critical habitat (or critical
habitat proposed for such designation), or until ESA section 7
consultation or conference has been completed. If the non-Federal
applicant has not heard back from the Corps within 45 days, the
applicant must still wait for notification from the Corps.
(d) As a result of formal or informal consultation or conference
with the FWS or NMFS the district engineer may add species-specific
permit conditions to the NWPs.
(e) Authorization of an activity by an NWP does not authorize the
``take'' of a threatened or endangered species as defined under the
ESA. In the absence of separate authorization (e.g., an ESA Section 10
Permit, a Biological Opinion with ``incidental take'' provisions, etc.)
from the FWS or the NMFS, the Endangered Species Act prohibits any
person subject to the jurisdiction of the United States to take a
listed species, where ``take'' means to harass, harm, pursue, hunt,
shoot, wound, kill, trap, capture, or collect, or to attempt to engage
in any such conduct. The word ``harm'' in the definition of ``take''
means an act which actually kills or injures wildlife. Such an act may
include significant habitat modification or degradation where it
actually kills or injures wildlife by significantly impairing essential
behavioral patterns, including breeding, feeding or sheltering.
(f) If the non-federal permittee has a valid ESA section
10(a)(1)(B) incidental take permit with an approved Habitat
Conservation Plan for a project or a group of projects that includes
the proposed NWP activity, the non-federal applicant should provide a
copy of that ESA section 10(a)(1)(B) permit with the PCN required by
paragraph (c) of this general condition. The district engineer will
coordinate with the agency that issued the ESA section 10(a)(1)(B)
permit to determine whether the proposed NWP activity and the
associated incidental take were considered in the internal ESA section
7 consultation conducted for the ESA section 10(a)(1)(B) permit. If
that coordination results in concurrence from the agency that the
proposed NWP activity and the associated incidental take were
considered in the internal ESA section 7 consultation for the ESA
section 10(a)(1)(B) permit, the district engineer does not need to
conduct a separate ESA section 7 consultation for the proposed NWP
activity. The district engineer will notify the non-federal applicant
within 45 days of receipt of a complete pre-construction notification
whether the ESA section 10(a)(1)(B) permit covers the proposed NWP
activity or whether additional ESA section 7 consultation is required.
(g) Information on the location of threatened and endangered
species and their critical habitat can be obtained directly from the
offices of the FWS and NMFS or their world wide web pages at http://www.fws.gov/ or http://www.fws.gov/ipac and http://www.nmfs.noaa.gov/pr/species/esa/ respectively.
19. Migratory Birds and Bald and Golden Eagles. The permittee is
responsible for ensuring that an action authorized by an NWP complies
with the Migratory Bird Treaty Act and the Bald and Golden Eagle
Protection Act. The permittee is responsible for contacting the
appropriate local office of the U.S. Fish and Wildlife Service to
determine what measures, if any, are necessary or appropriate to reduce
adverse effects to migratory birds or eagles, including whether
``incidental take'' permits are necessary and available under the
Migratory Bird Treaty Act or Bald and Golden Eagle Protection Act for a
particular activity.
20. Historic Properties. (a) No activity is authorized under any
NWP which may have the potential to cause effects to properties listed,
or eligible for listing, in the National Register of Historic Places
until the requirements of Section 106 of the National Historic
Preservation Act (NHPA) have been satisfied.
(b) Federal permittees should follow their own procedures for
complying with the requirements of section 106 of the National Historic
Preservation Act (see 33 CFR 330.4(g)(1)). If pre-construction
notification is required for the proposed NWP activity, the Federal
permittee must provide the district engineer with the appropriate
documentation to demonstrate compliance with those requirements. The
district engineer will verify that the appropriate documentation has
been submitted. If the appropriate
[[Page 2870]]
documentation is not submitted, then additional consultation under
section 106 may be necessary. The respective federal agency is
responsible for fulfilling its obligation to comply with section 106.
(c) Non-federal permittees must submit a pre-construction
notification to the district engineer if the NWP activity might have
the potential to cause effects to any historic properties listed on,
determined to be eligible for listing on, or potentially eligible for
listing on the National Register of Historic Places, including
previously unidentified properties. For such activities, the pre-
construction notification must state which historic properties might
have the potential to be affected by the proposed NWP activity or
include a vicinity map indicating the location of the historic
properties or the potential for the presence of historic properties.
Assistance regarding information on the location of, or potential for,
the presence of historic properties can be sought from the State
Historic Preservation Officer, Tribal Historic Preservation Officer, or
designated tribal representative, as appropriate, and the National
Register of Historic Places (see 33 CFR 330.4(g)). When reviewing pre-
construction notifications, district engineers will comply with the
current procedures for addressing the requirements of section 106 of
the National Historic Preservation Act. The district engineer shall
make a reasonable and good faith effort to carry out appropriate
identification efforts commensurate with potential impacts, which may
include background research, consultation, oral history interviews,
sample field investigation, and/or field survey. Based on the
information submitted in the PCN and these identification efforts, the
district engineer shall determine whether the proposed NWP activity has
the potential to cause effects on the historic properties. Section 106
consultation is not required when the district engineer determines that
the activity does not have the potential to cause effects on historic
properties (see 36 CFR 800.3(a)). Section 106 consultation is required
when the district engineer determines that the activity has the
potential to cause effects on historic properties. The district
engineer will conduct consultation with consulting parties identified
under 36 CFR 800.2(c) when he or she makes any of the following effect
determinations for the purposes of section 106 of the NHPA: No historic
properties affected, no adverse effect, or adverse effect.
(d) Where the non-Federal applicant has identified historic
properties on which the proposed NWP activity might have the potential
to cause effects and has so notified the Corps, the non-Federal
applicant shall not begin the activity until notified by the district
engineer either that the activity has no potential to cause effects to
historic properties or that NHPA section 106 consultation has been
completed. For non-federal permittees, the district engineer will
notify the prospective permittee within 45 days of receipt of a
complete pre-construction notification whether NHPA section 106
consultation is required. If NHPA section 106 consultation is required,
the district engineer will notify the non-Federal applicant that he or
she cannot begin the activity until section 106 consultation is
completed. If the non-Federal applicant has not heard back from the
Corps within 45 days, the applicant must still wait for notification
from the Corps.
(e) Prospective permittees should be aware that section 110k of the
NHPA (54 U.S.C. 306113) prevents the Corps from granting a permit or
other assistance to an applicant who, with intent to avoid the
requirements of section 106 of the NHPA, has intentionally
significantly adversely affected a historic property to which the
permit would relate, or having legal power to prevent it, allowed such
significant adverse effect to occur, unless the Corps, after
consultation with the Advisory Council on Historic Preservation (ACHP),
determines that circumstances justify granting such assistance despite
the adverse effect created or permitted by the applicant. If
circumstances justify granting the assistance, the Corps is required to
notify the ACHP and provide documentation specifying the circumstances,
the degree of damage to the integrity of any historic properties
affected, and proposed mitigation. This documentation must include any
views obtained from the applicant, SHPO/THPO, appropriate Indian tribes
if the undertaking occurs on or affects historic properties on tribal
lands or affects properties of interest to those tribes, and other
parties known to have a legitimate interest in the impacts to the
permitted activity on historic properties.
21. Discovery of Previously Unknown Remains and Artifacts.
Permittees that discover any previously unknown historic, cultural or
archeological remains and artifacts while accomplishing the activity
authorized by an NWP, they must immediately notify the district
engineer of what they have found, and to the maximum extent
practicable, avoid construction activities that may affect the remains
and artifacts until the required coordination has been completed. The
district engineer will initiate the Federal, Tribal, and state
coordination required to determine if the items or remains warrant a
recovery effort or if the site is eligible for listing in the National
Register of Historic Places.
22. Designated Critical Resource Waters. Critical resource waters
include, NOAA-managed marine sanctuaries and marine monuments, and
National Estuarine Research Reserves. The district engineer may
designate, after notice and opportunity for public comment, additional
waters officially designated by a state as having particular
environmental or ecological significance, such as outstanding national
resource waters or state natural heritage sites. The district engineer
may also designate additional critical resource waters after notice and
opportunity for public comment.
(a) Discharges of dredged or fill material into waters of the
United States are not authorized by NWPs 7, 12, 14, 16, 17, 21, 29, 31,
35, 39, 40, 42, 43, 44, 49, 50, 51, 52, 57 and 58 for any activity
within, or directly affecting, critical resource waters, including
wetlands adjacent to such waters.
(b) For NWPs 3, 8, 10, 13, 15, 18, 19, 22, 23, 25, 27, 28, 30, 33,
34, 36, 37, 38, and 54, notification is required in accordance with
general condition 32, for any activity proposed by permittees in the
designated critical resource waters including wetlands adjacent to
those waters. The district engineer may authorize activities under
these NWPs only after she or he determines that the impacts to the
critical resource waters will be no more than minimal.
23. Mitigation. The district engineer will consider the following
factors when determining appropriate and practicable mitigation
necessary to ensure that the individual and cumulative adverse
environmental effects are no more than minimal:
(a) The activity must be designed and constructed to avoid and
minimize adverse effects, both temporary and permanent, to waters of
the United States to the maximum extent practicable at the project site
(i.e., on site).
(b) Mitigation in all its forms (avoiding, minimizing, rectifying,
reducing, or compensating for resource losses) will be required to the
extent necessary to ensure that the individual and cumulative adverse
environmental effects are no more than minimal.
(c) Compensatory mitigation at a minimum one-for-one ratio will be
required for all wetland losses that exceed \1/10\-acre and require
pre-construction notification, unless the
[[Page 2871]]
district engineer determines in writing that either some other form of
mitigation would be more environmentally appropriate or the adverse
environmental effects of the proposed activity are no more than
minimal, and provides an activity-specific waiver of this requirement.
For wetland losses of \1/10\-acre or less that require pre-construction
notification, the district engineer may determine on a case-by-case
basis that compensatory mitigation is required to ensure that the
activity results in only minimal adverse environmental effects.
(d) Compensatory mitigation at a minimum one-for-one ratio will be
required for all losses of stream bed that exceed \3/100\-acre and
require pre-construction notification, unless the district engineer
determines in writing that either some other form of mitigation would
be more environmentally appropriate or the adverse environmental
effects of the proposed activity are no more than minimal, and provides
an activity-specific waiver of this requirement. This compensatory
mitigation requirement may be satisfied through the restoration or
enhancement of riparian areas next to streams in accordance with
paragraph (e) of this general condition. For losses of stream bed of
\3/100\-acre or less that require pre-construction notification, the
district engineer may determine on a case-by-case basis that
compensatory mitigation is required to ensure that the activity results
in only minimal adverse environmental effects. Compensatory mitigation
for losses of streams should be provided, if practicable, through
stream rehabilitation, enhancement, or preservation, since streams are
difficult-to-replace resources (see 33 CFR 332.3(e)(3)).
(e) Compensatory mitigation plans for NWP activities in or near
streams or other open waters will normally include a requirement for
the restoration or enhancement, maintenance, and legal protection
(e.g., conservation easements) of riparian areas next to open waters.
In some cases, the restoration or maintenance/protection of riparian
areas may be the only compensatory mitigation required. If restoring
riparian areas involves planting vegetation, only native species should
be planted. The width of the required riparian area will address
documented water quality or aquatic habitat loss concerns. Normally,
the riparian area will be 25 to 50 feet wide on each side of the
stream, but the district engineer may require slightly wider riparian
areas to address documented water quality or habitat loss concerns. If
it is not possible to restore or maintain/protect a riparian area on
both sides of a stream, or if the waterbody is a lake or coastal
waters, then restoring or maintaining/protecting a riparian area along
a single bank or shoreline may be sufficient. Where both wetlands and
open waters exist on the project site, the district engineer will
determine the appropriate compensatory mitigation (e.g., riparian areas
and/or wetlands compensation) based on what is best for the aquatic
environment on a watershed basis. In cases where riparian areas are
determined to be the most appropriate form of minimization or
compensatory mitigation, the district engineer may waive or reduce the
requirement to provide wetland compensatory mitigation for wetland
losses.
(f) Compensatory mitigation projects provided to offset losses of
aquatic resources must comply with the applicable provisions of 33 CFR
part 332.
(1) The prospective permittee is responsible for proposing an
appropriate compensatory mitigation option if compensatory mitigation
is necessary to ensure that the activity results in no more than
minimal adverse environmental effects. For the NWPs, the preferred
mechanism for providing compensatory mitigation is mitigation bank
credits or in-lieu fee program credits (see 33 CFR 332.3(b)(2) and
(3)). However, if an appropriate number and type of mitigation bank or
in-lieu credits are not available at the time the PCN is submitted to
the district engineer, the district engineer may approve the use of
permittee-responsible mitigation.
(2) The amount of compensatory mitigation required by the district
engineer must be sufficient to ensure that the authorized activity
results in no more than minimal individual and cumulative adverse
environmental effects (see 33 CFR 330.1(e)(3)). (See also 33 CFR
332.3(f).)
(3) Since the likelihood of success is greater and the impacts to
potentially valuable uplands are reduced, aquatic resource restoration
should be the first compensatory mitigation option considered for
permittee-responsible mitigation.
(4) If permittee-responsible mitigation is the proposed option, the
prospective permittee is responsible for submitting a mitigation plan.
A conceptual or detailed mitigation plan may be used by the district
engineer to make the decision on the NWP verification request, but a
final mitigation plan that addresses the applicable requirements of 33
CFR 332.4(c)(2) through (14) must be approved by the district engineer
before the permittee begins work in waters of the United States, unless
the district engineer determines that prior approval of the final
mitigation plan is not practicable or not necessary to ensure timely
completion of the required compensatory mitigation (see 33 CFR
332.3(k)(3)). If permittee-responsible mitigation is the proposed
option, and the proposed compensatory mitigation site is located on
land in which another federal agency holds an easement, the district
engineer will coordinate with that federal agency to determine if
proposed compensatory mitigation project is compatible with the terms
of the easement.
(5) If mitigation bank or in-lieu fee program credits are the
proposed option, the mitigation plan needs to address only the baseline
conditions at the impact site and the number of credits to be provided
(see 33 CFR 332.4(c)(1)(ii)).
(6) Compensatory mitigation requirements (e.g., resource type and
amount to be provided as compensatory mitigation, site protection,
ecological performance standards, monitoring requirements) may be
addressed through conditions added to the NWP authorization, instead of
components of a compensatory mitigation plan (see 33 CFR
332.4(c)(1)(ii)).
(g) Compensatory mitigation will not be used to increase the
acreage losses allowed by the acreage limits of the NWPs. For example,
if an NWP has an acreage limit of \1/2\-acre, it cannot be used to
authorize any NWP activity resulting in the loss of greater than \1/2\-
acre of waters of the United States, even if compensatory mitigation is
provided that replaces or restores some of the lost waters. However,
compensatory mitigation can and should be used, as necessary, to ensure
that an NWP activity already meeting the established acreage limits
also satisfies the no more than minimal impact requirement for the
NWPs.
(h) Permittees may propose the use of mitigation banks, in-lieu fee
programs, or permittee-responsible mitigation. When developing a
compensatory mitigation proposal, the permittee must consider
appropriate and practicable options consistent with the framework at 33
CFR 332.3(b). For activities resulting in the loss of marine or
estuarine resources, permittee-responsible mitigation may be
environmentally preferable if there are no mitigation banks or in-lieu
fee programs in the area that have marine or estuarine credits
available for sale or transfer to the permittee. For permittee-
responsible mitigation, the special conditions of the NWP verification
must clearly indicate the party or parties responsible for the
implementation and
[[Page 2872]]
performance of the compensatory mitigation project, and, if required,
its long-term management.
(i) Where certain functions and services of waters of the United
States are permanently adversely affected by a regulated activity, such
as discharges of dredged or fill material into waters of the United
States that will convert a forested or scrub-shrub wetland to a
herbaceous wetland in a permanently maintained utility line right-of-
way, mitigation may be required to reduce the adverse environmental
effects of the activity to the no more than minimal level.
24. Safety of Impoundment Structures. To ensure that all
impoundment structures are safely designed, the district engineer may
require non-Federal applicants to demonstrate that the structures
comply with established state or federal, dam safety criteria or have
been designed by qualified persons. The district engineer may also
require documentation that the design has been independently reviewed
by similarly qualified persons, and appropriate modifications made to
ensure safety.
25. Water Quality. (a) Where the certifying authority (state,
authorized tribe, or EPA, as appropriate) has not previously certified
compliance of an NWP with CWA section 401, a CWA section 401 water
quality certification for the proposed discharge must be obtained or
waived (see 33 CFR 330.4(c)). If the permittee cannot comply with all
of the conditions of a water quality certification previously issued by
certifying authority for the issuance of the NWP, then the permittee
must obtain a water quality certification or waiver for the proposed
discharge in order for the activity to be authorized by an NWP.
(b) If the NWP activity requires pre-construction notification and
the certifying authority has not previously certified compliance of an
NWP with CWA section 401, the proposed discharge is not authorized by
an NWP until water quality certification is obtained or waived. If the
certifying authority issues a water quality certification for the
proposed discharge, the permittee must submit a copy of the
certification to the district engineer. The discharge is not authorized
by an NWP until the district engineer has notified the permittee that
the water quality certification requirement has been satisfied by the
issuance of a water quality certification or a waiver.
(c) The district engineer or certifying authority may require
additional water quality management measures to ensure that the
authorized activity does not result in more than minimal degradation of
water quality.
26. Coastal Zone Management. In coastal states where an NWP has not
previously received a state coastal zone management consistency
concurrence, an individual state coastal zone management consistency
concurrence must be obtained, or a presumption of concurrence must
occur (see 33 CFR 330.4(d)). If the permittee cannot comply with all of
the conditions of a coastal zone management consistency concurrence
previously issued by the state, then the permittee must obtain an
individual coastal zone management consistency concurrence or
presumption of concurrence in order for the activity to be authorized
by an NWP. The district engineer or a state may require additional
measures to ensure that the authorized activity is consistent with
state coastal zone management requirements.
27. Regional and Case-By-Case Conditions. The activity must comply
with any regional conditions that may have been added by the Division
Engineer (see 33 CFR 330.4(e)) and with any case specific conditions
added by the Corps or by the state, Indian Tribe, or U.S. EPA in its
CWA section 401 Water Quality Certification, or by the state in its
Coastal Zone Management Act consistency determination.
28. Use of Multiple Nationwide Permits. The use of more than one
NWP for a single and complete project is authorized, subject to the
following restrictions:
(a) If only one of the NWPs used to authorize the single and
complete project has a specified acreage limit, the acreage loss of
waters of the United States cannot exceed the acreage limit of the NWP
with the highest specified acreage limit. For example, if a road
crossing over tidal waters is constructed under NWP 14, with associated
bank stabilization authorized by NWP 13, the maximum acreage loss of
waters of the United States for the total project cannot exceed \1/3\-
acre.
(b) If one or more of the NWPs used to authorize the single and
complete project has specified acreage limits, the acreage loss of
waters of the United States authorized by those NWPs cannot exceed
their respective specified acreage limits. For example, if a commercial
development is constructed under NWP 39, and the single and complete
project includes the filling of an upland ditch authorized by NWP 46,
the maximum acreage loss of waters of the United States for the
commercial development under NWP 39 cannot exceed \1/2\-acre, and the
total acreage loss of waters of United States due to the NWP 39 and 46
activities cannot exceed 1 acre.
29. Transfer of Nationwide Permit Verifications. If the permittee
sells the property associated with a nationwide permit verification,
the permittee may transfer the nationwide permit verification to the
new owner by submitting a letter to the appropriate Corps district
office to validate the transfer. A copy of the nationwide permit
verification must be attached to the letter, and the letter must
contain the following statement and signature:
``When the structures or work authorized by this nationwide permit
are still in existence at the time the property is transferred, the
terms and conditions of this nationwide permit, including any special
conditions, will continue to be binding on the new owner(s) of the
property. To validate the transfer of this nationwide permit and the
associated liabilities associated with compliance with its terms and
conditions, have the transferee sign and date below.''
-----------------------------------------------------------------------
(Transferee)
-----------------------------------------------------------------------
(Date)
30. Compliance Certification. Each permittee who receives an NWP
verification letter from the Corps must provide a signed certification
documenting completion of the authorized activity and implementation of
any required compensatory mitigation. The success of any required
permittee-responsible mitigation, including the achievement of
ecological performance standards, will be addressed separately by the
district engineer. The Corps will provide the permittee the
certification document with the NWP verification letter. The
certification document will include:
(a) A statement that the authorized activity was done in accordance
with the NWP authorization, including any general, regional, or
activity-specific conditions;
(b) A statement that the implementation of any required
compensatory mitigation was completed in accordance with the permit
conditions. If credits from a mitigation bank or in-lieu fee program
are used to satisfy the compensatory mitigation requirements, the
certification must include the documentation required by 33 CFR
332.3(l)(3) to confirm that the permittee secured the appropriate
number and resource type of credits; and
(c) The signature of the permittee certifying the completion of the
activity and mitigation.
[[Page 2873]]
The completed certification document must be submitted to the
district engineer within 30 days of completion of the authorized
activity or the implementation of any required compensatory mitigation,
whichever occurs later.
31. Activities Affecting Structures or Works Built by the United
States. If an NWP activity also requires review by, or permission from,
the Corps pursuant to 33 U.S.C. 408 because it will alter or
temporarily or permanently occupy or use a U.S. Army Corps of Engineers
(USACE) federally authorized Civil Works project (a ``USACE project''),
the prospective permittee must submit a pre-construction notification.
See paragraph (b)(10) of general condition 32. An activity that
requires section 408 permission and/or review is not authorized by an
NWP until the appropriate Corps office issues the section 408
permission or completes its review to alter, occupy, or use the USACE
project, and the district engineer issues a written NWP verification.
32. Pre-Construction Notification. (a) Timing. Where required by
the terms of the NWP, the prospective permittee must notify the
district engineer by submitting a pre-construction notification (PCN)
as early as possible. The district engineer must determine if the PCN
is complete within 30 calendar days of the date of receipt and, if the
PCN is determined to be incomplete, notify the prospective permittee
within that 30 day period to request the additional information
necessary to make the PCN complete. The request must specify the
information needed to make the PCN complete. As a general rule,
district engineers will request additional information necessary to
make the PCN complete only once. However, if the prospective permittee
does not provide all of the requested information, then the district
engineer will notify the prospective permittee that the PCN is still
incomplete and the PCN review process will not commence until all of
the requested information has been received by the district engineer.
The prospective permittee shall not begin the activity until either:
(1) He or she is notified in writing by the district engineer that
the activity may proceed under the NWP with any special conditions
imposed by the district or division engineer; or
(2) 45 calendar days have passed from the district engineer's
receipt of the complete PCN and the prospective permittee has not
received written notice from the district or division engineer.
However, if the permittee was required to notify the Corps pursuant to
general condition 18 that listed species or critical habitat might be
affected or are in the vicinity of the activity, or to notify the Corps
pursuant to general condition 20 that the activity might have the
potential to cause effects to historic properties, the permittee cannot
begin the activity until receiving written notification from the Corps
that there is ``no effect'' on listed species or ``no potential to
cause effects'' on historic properties, or that any consultation
required under Section 7 of the Endangered Species Act (see 33 CFR
330.4(f)) and/or section 106 of the National Historic Preservation Act
(see 33 CFR 330.4(g)) has been completed. If the proposed activity
requires a written waiver to exceed specified limits of an NWP, the
permittee may not begin the activity until the district engineer issues
the waiver. If the district or division engineer notifies the permittee
in writing that an individual permit is required within 45 calendar
days of receipt of a complete PCN, the permittee cannot begin the
activity until an individual permit has been obtained. Subsequently,
the permittee's right to proceed under the NWP may be modified,
suspended, or revoked only in accordance with the procedure set forth
in 33 CFR 330.5(d)(2).
(b) Contents of Pre-Construction Notification: The PCN must be in
writing and include the following information:
(1) Name, address and telephone numbers of the prospective
permittee;
(2) Location of the proposed activity;
(3) Identify the specific NWP or NWP(s) the prospective permittee
wants to use to authorize the proposed activity;
(4) (i) A description of the proposed activity; the activity's
purpose; direct and indirect adverse environmental effects the activity
would cause, including the anticipated amount of loss of wetlands,
other special aquatic sites, and other waters expected to result from
the NWP activity, in acres, linear feet, or other appropriate unit of
measure; a description of any proposed mitigation measures intended to
reduce the adverse environmental effects caused by the proposed
activity; and any other NWP(s), regional general permit(s), or
individual permit(s) used or intended to be used to authorize any part
of the proposed project or any related activity, including other
separate and distant crossings for linear projects that require
Department of the Army authorization but do not require pre-
construction notification. The description of the proposed activity and
any proposed mitigation measures should be sufficiently detailed to
allow the district engineer to determine that the adverse environmental
effects of the activity will be no more than minimal and to determine
the need for compensatory mitigation or other mitigation measures.
(ii) For linear projects where one or more single and complete
crossings require pre-construction notification, the PCN must include
the quantity of anticipated losses of wetlands, other special aquatic
sites, and other waters for each single and complete crossing of those
wetlands, other special aquatic sites, and other waters (including
those single and complete crossings authorized by an NWP but do not
require PCNs). This information will be used by the district engineer
to evaluate the cumulative adverse environmental effects of the
proposed linear project, and does not change those non-PCN NWP
activities into NWP PCNs.
(iii) Sketches should be provided when necessary to show that the
activity complies with the terms of the NWP. (Sketches usually clarify
the activity and when provided results in a quicker decision. Sketches
should contain sufficient detail to provide an illustrative description
of the proposed activity (e.g., a conceptual plan), but do not need to
be detailed engineering plans);
(5) The PCN must include a delineation of wetlands, other special
aquatic sites, and other waters, such as lakes and ponds, and perennial
and intermittent streams, on the project site. Wetland delineations
must be prepared in accordance with the current method required by the
Corps. The permittee may ask the Corps to delineate the special aquatic
sites and other waters on the project site, but there may be a delay if
the Corps does the delineation, especially if the project site is large
or contains many wetlands, other special aquatic sites, and other
waters. Furthermore, the 45-day period will not start until the
delineation has been submitted to or completed by the Corps, as
appropriate;
(6) If the proposed activity will result in the loss of greater
than \1/10\-acre of wetlands or \3/100\-acre of stream bed and a PCN is
required, the prospective permittee must submit a statement describing
how the mitigation requirement will be satisfied, or explaining why the
adverse environmental effects are no more than minimal and why
compensatory mitigation should not be required. As an alternative, the
prospective permittee may submit a conceptual or detailed mitigation
plan.
(7) For non-federal permittees, if any listed species (or species
proposed for listing) or designated critical habitat (or critical
habitat proposed for such
[[Page 2874]]
designation) might be affected or is in the vicinity of the activity,
or if the activity is located in designated critical habitat (or
critical habitat proposed for such designation), the PCN must include
the name(s) of those endangered or threatened species (or species
proposed for listing) that might be affected by the proposed activity
or utilize the designated critical habitat (or critical habitat
proposed for such designation) that might be affected by the proposed
activity. For NWP activities that require pre-construction
notification, Federal permittees must provide documentation
demonstrating compliance with the Endangered Species Act;
(8) For non-federal permittees, if the NWP activity might have the
potential to cause effects to a historic property listed on, determined
to be eligible for listing on, or potentially eligible for listing on,
the National Register of Historic Places, the PCN must state which
historic property might have the potential to be affected by the
proposed activity or include a vicinity map indicating the location of
the historic property. For NWP activities that require pre-construction
notification, Federal permittees must provide documentation
demonstrating compliance with section 106 of the National Historic
Preservation Act;
(9) For an activity that will occur in a component of the National
Wild and Scenic River System, or in a river officially designated by
Congress as a ``study river'' for possible inclusion in the system
while the river is in an official study status, the PCN must identify
the Wild and Scenic River or the ``study river'' (see general condition
16); and
(10) For an NWP activity that requires permission from, or review
by, the Corps pursuant to 33 U.S.C. 408 because it will alter or
temporarily or permanently occupy or use a U.S. Army Corps of Engineers
federally authorized civil works project, the pre-construction
notification must include a statement confirming that the project
proponent has submitted a written request for section 408 permission
from, or review by, the Corps office having jurisdiction over that
USACE project.
(c) Form of Pre-Construction Notification: The nationwide permit
pre-construction notification form (Form ENG 6082) should be used for
NWP PCNs. A letter containing the required information may also be
used. Applicants may provide electronic files of PCNs and supporting
materials if the district engineer has established tools and procedures
for electronic submittals.
(d) Agency Coordination: (1) The district engineer will consider
any comments from Federal and state agencies concerning the proposed
activity's compliance with the terms and conditions of the NWPs and the
need for mitigation to reduce the activity's adverse environmental
effects so that they are no more than minimal.
(2) Agency coordination is required for: (i) All NWP activities
that require pre-construction notification and result in the loss of
greater than \1/2\-acre of waters of the United States; (ii) NWP 13
activities in excess of 500 linear feet, fills greater than one cubic
yard per running foot, or involve discharges of dredged or fill
material into special aquatic sites; and (iii) NWP 54 activities in
excess of 500 linear feet, or that extend into the waterbody more than
30 feet from the mean low water line in tidal waters or the ordinary
high water mark in the Great Lakes.
(3) When agency coordination is required, the district engineer
will immediately provide (e.g., via email, facsimile transmission,
overnight mail, or other expeditious manner) a copy of the complete PCN
to the appropriate Federal or state offices (FWS, state natural
resource or water quality agency, EPA, and, if appropriate, the NMFS).
With the exception of NWP 37, these agencies will have 10 calendar days
from the date the material is transmitted to notify the district
engineer via telephone, facsimile transmission, or email that they
intend to provide substantive, site-specific comments. The comments
must explain why the agency believes the adverse environmental effects
will be more than minimal. If so contacted by an agency, the district
engineer will wait an additional 15 calendar days before making a
decision on the pre-construction notification. The district engineer
will fully consider agency comments received within the specified time
frame concerning the proposed activity's compliance with the terms and
conditions of the NWPs, including the need for mitigation to ensure
that the net adverse environmental effects of the proposed activity are
no more than minimal. The district engineer will provide no response to
the resource agency, except as provided below. The district engineer
will indicate in the administrative record associated with each pre-
construction notification that the resource agencies' concerns were
considered. For NWP 37, the emergency watershed protection and
rehabilitation activity may proceed immediately in cases where there is
an unacceptable hazard to life or a significant loss of property or
economic hardship will occur. The district engineer will consider any
comments received to decide whether the NWP 37 authorization should be
modified, suspended, or revoked in accordance with the procedures at 33
CFR 330.5.
(4) In cases of where the prospective permittee is not a Federal
agency, the district engineer will provide a response to NMFS within 30
calendar days of receipt of any Essential Fish Habitat conservation
recommendations, as required by section 305(b)(4)(B) of the Magnuson-
Stevens Fishery Conservation and Management Act.
(5) Applicants are encouraged to provide the Corps with either
electronic files or multiple copies of pre-construction notifications
to expedite agency coordination.
D. District Engineer's Decision
1. In reviewing the PCN for the proposed activity, the district
engineer will determine whether the activity authorized by the NWP will
result in more than minimal individual or cumulative adverse
environmental effects or may be contrary to the public interest. If a
project proponent requests authorization by a specific NWP, the
district engineer should issue the NWP verification for that activity
if it meets the terms and conditions of that NWP, unless he or she
determines, after considering mitigation, that the proposed activity
will result in more than minimal individual and cumulative adverse
effects on the aquatic environment and other aspects of the public
interest and exercises discretionary authority to require an individual
permit for the proposed activity. For a linear project, this
determination will include an evaluation of the single and complete
crossings of waters of the United States that require PCNs to determine
whether they individually satisfy the terms and conditions of the
NWP(s), as well as the cumulative effects caused by all of the
crossings of waters of the United States authorized by an NWP. If an
applicant requests a waiver of an applicable limit, as provided for in
NWPs 13, 36, or 54, the district engineer will only grant the waiver
upon a written determination that the NWP activity will result in only
minimal individual and cumulative adverse environmental effects.
2. When making minimal adverse environmental effects determinations
the district engineer will consider the direct and indirect effects
caused by the NWP activity. He or she will also consider the cumulative
adverse environmental effects caused by activities authorized by an NWP
and whether those cumulative adverse
[[Page 2875]]
environmental effects are no more than minimal. The district engineer
will also consider site specific factors, such as the environmental
setting in the vicinity of the NWP activity, the type of resource that
will be affected by the NWP activity, the functions provided by the
aquatic resources that will be affected by the NWP activity, the degree
or magnitude to which the aquatic resources perform those functions,
the extent that aquatic resource functions will be lost as a result of
the NWP activity (e.g., partial or complete loss), the duration of the
adverse effects (temporary or permanent), the importance of the aquatic
resource functions to the region (e.g., watershed or ecoregion), and
mitigation required by the district engineer. If an appropriate
functional or condition assessment method is available and practicable
to use, that assessment method may be used by the district engineer to
assist in the minimal adverse environmental effects determination. The
district engineer may add case-specific special conditions to the NWP
authorization to address site-specific environmental concerns.
3. If the proposed activity requires a PCN and will result in a
loss of greater than \1/10\-acre of wetlands or \3/100\-acre of stream
bed, the prospective permittee should submit a mitigation proposal with
the PCN. Applicants may also propose compensatory mitigation for NWP
activities with smaller impacts, or for impacts to other types of
waters. The district engineer will consider any proposed compensatory
mitigation or other mitigation measures the applicant has included in
the proposal in determining whether the net adverse environmental
effects of the proposed activity are no more than minimal. The
compensatory mitigation proposal may be either conceptual or detailed.
If the district engineer determines that the activity complies with the
terms and conditions of the NWP and that the adverse environmental
effects are no more than minimal, after considering mitigation, the
district engineer will notify the permittee and include any activity-
specific conditions in the NWP verification the district engineer deems
necessary. Conditions for compensatory mitigation requirements must
comply with the appropriate provisions at 33 CFR 332.3(k). The district
engineer must approve the final mitigation plan before the permittee
commences work in waters of the United States, unless the district
engineer determines that prior approval of the final mitigation plan is
not practicable or not necessary to ensure timely completion of the
required compensatory mitigation. If the prospective permittee elects
to submit a compensatory mitigation plan with the PCN, the district
engineer will expeditiously review the proposed compensatory mitigation
plan. The district engineer must review the proposed compensatory
mitigation plan within 45 calendar days of receiving a complete PCN and
determine whether the proposed mitigation would ensure that the NWP
activity results in no more than minimal adverse environmental effects.
If the net adverse environmental effects of the NWP activity (after
consideration of the mitigation proposal) are determined by the
district engineer to be no more than minimal, the district engineer
will provide a timely written response to the applicant. The response
will state that the NWP activity can proceed under the terms and
conditions of the NWP, including any activity-specific conditions added
to the NWP authorization by the district engineer.
4. If the district engineer determines that the adverse
environmental effects of the proposed activity are more than minimal,
then the district engineer will notify the applicant either: (a) That
the activity does not qualify for authorization under the NWP and
instruct the applicant on the procedures to seek authorization under an
individual permit; (b) that the activity is authorized under the NWP
subject to the applicant's submission of a mitigation plan that would
reduce the adverse environmental effects so that they are no more than
minimal; or (c) that the activity is authorized under the NWP with
specific modifications or conditions. Where the district engineer
determines that mitigation is required to ensure no more than minimal
adverse environmental effects, the activity will be authorized within
the 45-day PCN period (unless additional time is required to comply
with general conditions 18, 20, and/or 31), with activity-specific
conditions that state the mitigation requirements. The authorization
will include the necessary conceptual or detailed mitigation plan or a
requirement that the applicant submit a mitigation plan that would
reduce the adverse environmental effects so that they are no more than
minimal. When compensatory mitigation is required, no work in waters of
the United States may occur until the district engineer has approved a
specific mitigation plan or has determined that prior approval of a
final mitigation plan is not practicable or not necessary to ensure
timely completion of the required compensatory mitigation.
E. Further Information
1. District engineers have authority to determine if an activity
complies with the terms and conditions of an NWP.
2. NWPs do not obviate the need to obtain other federal, state, or
local permits, approvals, or authorizations required by law.
3. NWPs do not grant any property rights or exclusive privileges.
4. NWPs do not authorize any injury to the property or rights of
others.
5. NWPs do not authorize interference with any existing or proposed
Federal project (see general condition 31).
F. Definitions
Best management practices (BMPs): Policies, practices, procedures,
or structures implemented to mitigate the adverse environmental effects
on surface water quality resulting from development. BMPs are
categorized as structural or non-structural.
Compensatory mitigation: The restoration (re-establishment or
rehabilitation), establishment (creation), enhancement, and/or in
certain circumstances preservation of aquatic resources for the
purposes of offsetting unavoidable adverse impacts which remain after
all appropriate and practicable avoidance and minimization has been
achieved.
Currently serviceable: Useable as is or with some maintenance, but
not so degraded as to essentially require reconstruction.
Direct effects: Effects that are caused by the activity and occur
at the same time and place.
Discharge: The term ``discharge'' means any discharge of dredged or
fill material into waters of the United States.
Ecological reference: A model used to plan and design an aquatic
habitat and riparian area restoration, enhancement, or establishment
activity under NWP 27. An ecological reference may be based on the
structure, functions, and dynamics of an aquatic habitat type or a
riparian area type that currently exists in the region where the
proposed NWP 27 activity is located. Alternatively, an ecological
reference may be based on a conceptual model for the aquatic habitat
type or riparian area type to be restored, enhanced, or established as
a result of the proposed NWP 27 activity. An ecological reference takes
into account the range of variation of the aquatic habitat type or
riparian area type in the region.
Enhancement: The manipulation of the physical, chemical, or
biological
[[Page 2876]]
characteristics of an aquatic resource to heighten, intensify, or
improve a specific aquatic resource function(s). Enhancement results in
the gain of selected aquatic resource function(s), but may also lead to
a decline in other aquatic resource function(s). Enhancement does not
result in a gain in aquatic resource area.
Establishment (creation): The manipulation of the physical,
chemical, or biological characteristics present to develop an aquatic
resource that did not previously exist at an upland site. Establishment
results in a gain in aquatic resource area.
High Tide Line: The line of intersection of the land with the
water's surface at the maximum height reached by a rising tide. The
high tide line may be determined, in the absence of actual data, by a
line of oil or scum along shore objects, a more or less continuous
deposit of fine shell or debris on the foreshore or berm, other
physical markings or characteristics, vegetation lines, tidal gages, or
other suitable means that delineate the general height reached by a
rising tide. The line encompasses spring high tides and other high
tides that occur with periodic frequency but does not include storm
surges in which there is a departure from the normal or predicted reach
of the tide due to the piling up of water against a coast by strong
winds such as those accompanying a hurricane or other intense storm.
Historic Property: Any prehistoric or historic district, site
(including archaeological site), building, structure, or other object
included in, or eligible for inclusion in, the National Register of
Historic Places maintained by the Secretary of the Interior. This term
includes artifacts, records, and remains that are related to and
located within such properties. The term includes properties of
traditional religious and cultural importance to an Indian tribe or
Native Hawaiian organization and that meet the National Register
criteria (36 CFR part 60).
Independent utility: A test to determine what constitutes a single
and complete non-linear project in the Corps Regulatory Program. A
project is considered to have independent utility if it would be
constructed absent the construction of other projects in the project
area. Portions of a multi-phase project that depend upon other phases
of the project do not have independent utility. Phases of a project
that would be constructed even if the other phases were not built can
be considered as separate single and complete projects with independent
utility.
Indirect effects: Effects that are caused by the activity and are
later in time or farther removed in distance, but are still reasonably
foreseeable.
Loss of waters of the United States: Waters of the United States
that are permanently adversely affected by filling, flooding,
excavation, or drainage because of the regulated activity. The loss of
stream bed includes the acres of stream bed that are permanently
adversely affected by filling or excavation because of the regulated
activity. Permanent adverse effects include permanent discharges of
dredged or fill material that change an aquatic area to dry land,
increase the bottom elevation of a waterbody, or change the use of a
waterbody. The acreage of loss of waters of the United States is a
threshold measurement of the impact to jurisdictional waters or
wetlands for determining whether a project may qualify for an NWP; it
is not a net threshold that is calculated after considering
compensatory mitigation that may be used to offset losses of aquatic
functions and services. Waters of the United States temporarily filled,
flooded, excavated, or drained, but restored to pre-construction
contours and elevations after construction, are not included in the
measurement of loss of waters of the United States. Impacts resulting
from activities that do not require Department of the Army
authorization, such as activities eligible for exemptions under section
404(f) of the Clean Water Act, are not considered when calculating the
loss of waters of the United States.
Navigable waters: Waters subject to section 10 of the Rivers and
Harbors Act of 1899. These waters are defined at 33 CFR part 329.
Non-tidal wetland: A non-tidal wetland is a wetland that is not
subject to the ebb and flow of tidal waters. Non-tidal wetlands
contiguous to tidal waters are located landward of the high tide line
(i.e., spring high tide line).
Open water: For purposes of the NWPs, an open water is any area
that in a year with normal patterns of precipitation has water flowing
or standing above ground to the extent that an ordinary high water mark
can be determined. Aquatic vegetation within the area of flowing or
standing water is either non-emergent, sparse, or absent. Vegetated
shallows are considered to be open waters. Examples of ``open waters''
include rivers, streams, lakes, and ponds.
Ordinary High Water Mark: The term ordinary high water mark means
that line on the shore established by the fluctuations of water and
indicated by physical characteristics such as a clear, natural line
impressed on the bank, shelving, changes in the character of soil,
destruction of terrestrial vegetation, the presence of litter and
debris, or other appropriate means that consider the characteristics of
the surrounding areas.
Perennial stream: A perennial stream has surface water flowing
continuously year-round during a typical year.
Practicable: Available and capable of being done after taking into
consideration cost, existing technology, and logistics in light of
overall project purposes.
Pre-construction notification: A request submitted by the project
proponent to the Corps for confirmation that a particular activity is
authorized by nationwide permit. The request may be a permit
application, letter, or similar document that includes information
about the proposed work and its anticipated environmental effects. Pre-
construction notification may be required by the terms and conditions
of a nationwide permit, or by regional conditions. A pre-construction
notification may be voluntarily submitted in cases where pre-
construction notification is not required and the project proponent
wants confirmation that the activity is authorized by nationwide
permit.
Preservation: The removal of a threat to, or preventing the decline
of, aquatic resources by an action in or near those aquatic resources.
This term includes activities commonly associated with the protection
and maintenance of aquatic resources through the implementation of
appropriate legal and physical mechanisms. Preservation does not result
in a gain of aquatic resource area or functions.
Re-establishment: The manipulation of the physical, chemical, or
biological characteristics of a site with the goal of returning
natural/historic functions to a former aquatic resource. Re-
establishment results in rebuilding a former aquatic resource and
results in a gain in aquatic resource area and functions.
Rehabilitation: The manipulation of the physical, chemical, or
biological characteristics of a site with the goal of repairing
natural/historic functions to a degraded aquatic resource.
Rehabilitation results in a gain in aquatic resource function, but does
not result in a gain in aquatic resource area.
Restoration: The manipulation of the physical, chemical, or
biological characteristics of a site with the goal of returning
natural/historic functions to a former or degraded aquatic resource.
For the purpose of tracking net gains in aquatic resource area,
restoration is
[[Page 2877]]
divided into two categories: Re-establishment and rehabilitation.
Riffle and pool complex: Riffle and pool complexes are special
aquatic sites under the 404(b)(1) Guidelines. Riffle and pool complexes
sometimes characterize steep gradient sections of streams. Such stream
sections are recognizable by their hydraulic characteristics. The rapid
movement of water over a course substrate in riffles results in a rough
flow, a turbulent surface, and high dissolved oxygen levels in the
water. Pools are deeper areas associated with riffles. A slower stream
velocity, a streaming flow, a smooth surface, and a finer substrate
characterize pools.
Riparian areas: Riparian areas are lands next to streams, lakes,
and estuarine-marine shorelines. Riparian areas are transitional
between terrestrial and aquatic ecosystems, through which surface and
subsurface hydrology connects riverine, lacustrine, estuarine, and
marine waters with their adjacent wetlands, non-wetland waters, or
uplands. Riparian areas provide a variety of ecological functions and
services and help improve or maintain local water quality. (See general
condition 23.)
Shellfish seeding: The placement of shellfish seed and/or suitable
substrate to increase shellfish production. Shellfish seed consists of
immature individual shellfish or individual shellfish attached to
shells or shell fragments (i.e., spat on shell). Suitable substrate may
consist of shellfish shells, shell fragments, or other appropriate
materials placed into waters for shellfish habitat.
Single and complete linear project: A linear project is a project
constructed for the purpose of getting people, goods, or services from
a point of origin to a terminal point, which often involves multiple
crossings of one or more waterbodies at separate and distant locations.
The term ``single and complete project'' is defined as that portion of
the total linear project proposed or accomplished by one owner/
developer or partnership or other association of owners/developers that
includes all crossings of a single water of the United States (i.e., a
single waterbody) at a specific location. For linear projects crossing
a single or multiple waterbodies several times at separate and distant
locations, each crossing is considered a single and complete project
for purposes of NWP authorization. However, individual channels in a
braided stream or river, or individual arms of a large, irregularly
shaped wetland or lake, etc., are not separate waterbodies, and
crossings of such features cannot be considered separately.
Single and complete non-linear project: For non-linear projects,
the term ``single and complete project'' is defined at 33 CFR 330.2(i)
as the total project proposed or accomplished by one owner/developer or
partnership or other association of owners/developers. A single and
complete non-linear project must have independent utility (see
definition of ``independent utility''). Single and complete non-linear
projects may not be ``piecemealed'' to avoid the limits in an NWP
authorization.
Stormwater management: Stormwater management is the mechanism for
controlling stormwater runoff for the purposes of reducing downstream
erosion, water quality degradation, and flooding and mitigating the
adverse effects of changes in land use on the aquatic environment.
Stormwater management facilities: Stormwater management facilities
are those facilities, including but not limited to, stormwater
retention and detention ponds and best management practices, which
retain water for a period of time to control runoff and/or improve the
quality (i.e., by reducing the concentration of nutrients, sediments,
hazardous substances and other pollutants) of stormwater runoff.
Stream bed: The substrate of the stream channel between the
ordinary high water marks. The substrate may be bedrock or inorganic
particles that range in size from clay to boulders. Wetlands contiguous
to the stream bed, but outside of the ordinary high water marks, are
not considered part of the stream bed.
Stream channelization: The manipulation of a stream's course,
condition, capacity, or location that causes more than minimal
interruption of normal stream processes. A channelized jurisdictional
stream remains a water of the United States.
Structure: An object that is arranged in a definite pattern of
organization. Examples of structures include, without limitation, any
pier, boat dock, boat ramp, wharf, dolphin, weir, boom, breakwater,
bulkhead, revetment, riprap, jetty, artificial island, artificial reef,
permanent mooring structure, power transmission line, permanently
moored floating vessel, piling, aid to navigation, or any other manmade
obstacle or obstruction.
Tidal wetland: A tidal wetland is a jurisdictional wetland that is
inundated by tidal waters. Tidal waters rise and fall in a predictable
and measurable rhythm or cycle due to the gravitational pulls of the
moon and sun. Tidal waters end where the rise and fall of the water
surface can no longer be practically measured in a predictable rhythm
due to masking by other waters, wind, or other effects. Tidal wetlands
are located channelward of the high tide line.
Tribal lands: Any lands title to which is either: (1) Held in trust
by the United States for the benefit of any Indian tribe or individual;
or (2) held by any Indian tribe or individual subject to restrictions
by the United States against alienation.
Tribal rights: Those rights legally accruing to a tribe or tribes
by virtue of inherent sovereign authority, unextinguished aboriginal
title, treaty, statute, judicial decisions, executive order or
agreement, and that give rise to legally enforceable remedies.
Vegetated shallows: Vegetated shallows are special aquatic sites
under the 404(b)(1) Guidelines. They are areas that are permanently
inundated and under normal circumstances have rooted aquatic
vegetation, such as seagrasses in marine and estuarine systems and a
variety of vascular rooted plants in freshwater systems.
Waterbody: For purposes of the NWPs, a waterbody is a ``water of
the United States.'' If a wetland is adjacent to a waterbody determined
to be a water of the United States, that waterbody and any adjacent
wetlands are considered together as a single aquatic unit (see 33 CFR
328.4(c)(2)).
