Hazardous and Solid Waste Management System: Disposal of Coal
Combustion Residuals From Electric Utilities; Legacy CCR Surface
Impoundments
AGENCY: Environmental Protection Agency (EPA).
ACTION: Advance notice of proposed rulemaking.
-----------------------------------------------------------------------
SUMMARY: On April 17, 2015, the Environmental Protection Agency (EPA or
the Agency) promulgated national minimum criteria for existing and new
coal combustion residuals (CCR) landfills and existing and new CCR
surface impoundments. On August 21, 2018, the U.S. Court of Appeals for
the District of Columbia Circuit issued its opinion in the case of
Utility Solid Waste Activities Group, et al. v. EPA, which vacated and
remanded the provision that exempted inactive impoundments at inactive
facilities from the CCR regulations. As a first step to implement this
part of the court decision, EPA is seeking comments in this advanced
notice of proposed rulemaking (ANPRM) and data on inactive surface
impoundments at inactive facilities to assist in the development of
future regulations for these CCR units. This ANPRM also discusses the
related research conducted to date, describes EPA's preliminary
analysis of that research, and seeks additional data and public input
on issues that may inform a future proposed rule.

II. General Information
A. Does this action apply to me?
A future rulemaking for inactive (``legacy'') CCR surface
impoundments potentially applies to owners and operators of all CCR
generated by electric utilities and independent power producers that
fall within the North American Industry Classification System (NAICS)
code 221112 and may affect the following entities: Electric utility
facilities and independent power producers that fall under the NAICS
code 221112. This discussion is not intended to be exhaustive, but
rather provides a guide for readers regarding entities likely to be
regulated by this action. This discussion lists the types of entities
that EPA is now aware could potentially be regulated by this action.
Other types of entities not described here could also be regulated. To
determine whether your entity is regulated by this action, you should
carefully examine the applicability criteria found in Sec. 257.50 of
title 40 of the Code of Federal Regulations. If you have questions
regarding the applicability of this action to a particular entity,
consult the person listed in the FOR FURTHER INFORMATION CONTACT
section.
B. What action is the Agency contemplating?
EPA is seeking comments and data on legacy CCR surface impoundments
at inactive facilities to assist in the development of future
regulations for these CCR units. This action is in response to the
August 21, 2018 opinion by the U.S. Court of Appeals for the District
of Columbia Circuit (Utility Solid Waste Activities Group, et al. v.
EPA) that vacated and remanded the provision that exempted inactive
impoundments at inactive facilities from the 2015 CCR rule.
By this document, EPA is seeking public input on key issues at this
preliminary stage to inform its thinking on any future proposed
rulemaking. EPA is not reopening any existing regulations through this
ANPRM.
C. What is the Agency's authority for taking this action?
EPA is publishing this document under the authority of sections
1008(a), 2002(a), 4004, and 4005(a) and (d) of the Solid Waste Disposal
Act of 1970, as amended by the Resource Conservation and Recovery Act
of 1976 (RCRA), as amended by the Hazardous and Solid Waste Amendments
of 1984 (HSWA) and the Water Infrastructure Improvements for the Nation
(WIIN) Act of 2016, 42 U.S.C. 6907(a), 6912(a), 6944, and 6945(a) and
(d).
III. Background
On April 17, 2015, EPA finalized national minimum criteria for the
disposal of CCR as solid waste under Subtitle D of the Resource
Conservation and Recovery Act (RCRA) titled, ``Hazardous and Solid
Waste Management System; Disposal of Coal Combustion Residuals from
Electric Utilities,'' (80 FR 21302) (2015 CCR rule or CCR regulations).
The 2015 CCR rule, codified in subpart D of part 257 of Title 40 of the
Code of Federal Regulations, established regulations for existing and
new CCR landfills and existing and new CCR surface impoundments and all
lateral expansions of CCR units. The criteria consist of location
restrictions, design and operating criteria, groundwater monitoring and
corrective action requirements, closure and post-closure care
requirements, recordkeeping, notification and internet posting
requirements.
The 2015 CCR rule regulated existing and new CCR landfills and
existing and new CCR surface impoundments and all lateral expansions of
CCR units. The rule also imposed requirements on inactive surface
impoundments \1\ at active facilities,\2\ but did not impose
[[Page 65017]]
requirements on inactive surface impoundments at inactive facilities.
The preamble to the 2015 CCR final rule (80 FR 21344) explained that
inactive units at inactive facilities were not covered by the rule in
part due to possible complications that were specific to inactive or
closed facilities: The concern that the present owner of the land on
which an inactive site was located might have no connection (other than
present ownership of the land) with the prior disposal activities. For
that reason, EPA exempted those units at Sec. 257.50(e).
---------------------------------------------------------------------------
\1\ An ``inactive CCR surface impoundment'' is defined at Sec.
257.53 as a CCR surface impoundment that no longer received CCR on
or after October 19, 2015 and still contains both CCR and liquids on
or after October 19, 2015.
\2\ An ``active facility or active electric utilities or
independent power producers'' is defined at Sec. 257.53 as any
facility subject to the requirements of this subpart that is in
operation on October 19, 2015. An electric utility or independent
power producer is in operation if it is generating electricity that
is provided to electric power transmission systems or to electric
power distribution systems on or after October 19, 2015. An off-site
disposal facility is in operation if it is accepting or managing CCR
on or after October 19, 2015.
---------------------------------------------------------------------------
The rule was challenged by several parties, including a coalition
of regulated entities and a coalition of environmental organizations
(``Environmental Petitioners''). Environmental Petitioners raised two
challenges that are relevant to this ANPRM: First, they challenged the
provision that allowed existing, unlined surface impoundments to
continue to operate until they exceeded the groundwater protection
standard. See Sec. 257.101(a)(1). They contended that EPA failed to
show how continued operation of unlined impoundments met RCRA's
baseline requirement that any solid waste disposal site pose ``no
reasonable probability of adverse effects on health or the
environment.'' 42 U.S.C. 6944(a). Secondly, Environmental Petitioners
challenged the provisions exempting inactive surface impoundments at
inactive power plants (i.e., ``legacy ponds'') from regulation. The
environmental petitioners argued that legacy ponds are at risk of
unmonitored leaks and catastrophic structural failures. The U.S. Court
of Appeals for the D.C. Circuit issued its decision on August 21, 2018.
The Court upheld most of the rule but ruled for the environmental
petitioners on these two claims. The court held that EPA acted
``arbitrarily and capriciously and contrary to RCRA'' in failing to
require the closure of unlined surface impoundments \3\ and in
exempting inactive surface impoundments at inactive power plants from
regulation. The court ordered that these provisions be vacated and
remanded back to the Agency. Utility Solid Waste Activities Group
(USWAG), et al. v. EPA, 901 F.3d 414 (D.C. Cir. 2018). This decision is
referred to as the `USWAG decision' in this ANPRM.
---------------------------------------------------------------------------
\3\ Unlined CCR surface impoundments were addressed in a
separate regulatory action that was published on August 28, 2020 (85
FR 53516).
---------------------------------------------------------------------------
In overturning the exemption for legacy ponds, the court pointed to
evidence from the 2015 CCR rule that legacy ponds are most likely to be
unlined and unmonitored and have been shown to be more likely to leak
than units at utilities still in operation, therefore these units are
at risk of leaks and catastrophic structural failures. The court stated
that legacy ponds pose the same threats to human health and the
environment as the riskiest coal residuals disposal methods, compounded
by diminished preventative and remediation oversight due to the absence
of an onsite owner and daily monitoring. See 80 FR at 21343 through
21344 (finding that the greatest disposal risks are ``primarily driven
by the older existing units, which are generally unlined''). For these
reasons, the court vacated and remanded the provision of the 2015 CCR
rule that exempted inactive impoundments at inactive facilities from
regulation, at Sec. 257.50(e). Until EPA finalizes amendments to the
regulations to effectuate the court's order, facilities are not legally
obliged to take any action to comply with the federal CCR regulations.
As currently drafted, nothing in Sec. 257.50 would bring inactive
surface impoundments at inactive facilities within the scope of the
federal CCR regulations.
IV. What information is EPA seeking?
In this action, EPA is seeking additional information related to
inactive surface impoundments at inactive facilities, referred to as
``legacy'' CCR surface impoundments throughout this preamble, to better
inform a future rulemaking. The Agency is seeking input on regulatory
authority and a potential definition of a legacy CCR surface
impoundment. It is also soliciting specific information on the types of
inactive surface impoundments at inactive facilities that might be
considered legacy CCR surface impoundments. In particular, EPA is
requesting information on how many of these units might exist, their
current status (e.g., capped, dry, closed according to state
requirements, still holding water), and names and locations of former
power plants that may have these units and when they closed. Finally,
the Agency is taking comment on which CCR regulations should apply to
legacy CCR surface impoundments and on suggestions for timeframes that
EPA should prescribe for coming into compliance with those regulations.
A. EPA Regulatory Authority
As discussed in the preamble to the final 2015 CCR rule (80 FR
21302, April 17, 2015), EPA has previously interpreted RCRA subtitle D
to grant it the authority to regulate both active units--i.e., those
landfills and impoundments that receive waste after the effective date
of the regulation--and inactive units--those landfills and impoundments
which ceased receiving waste before the effective date of the
regulation. 80 FR at 21342 through 21346.
A challenge to this interpretation in the context of EPA's
regulation of inactive units at currently operating power plants in the
2015 CCR rule was rejected by a panel of the D.C. Circuit in Utility
Solid Waste Activities Group, et al. v. EPA, 901 F.3d 414 (D.C. Cir.
2018) (``USWAG decision''), which concluded that ``resolution of this
issue begins and ends with RCRA's plain text.'' Id. at 440. The court
focused on the phrase ``is disposed of'' in the statutory definition of
an open dump, concluding that ``while the `is' retains its active
present tense, the `disposal' takes the form of a past participle
(`disposed').'' In this way the disposal itself can exist (`it is')
even if the act of disposal took place at some prior time.'' Id.
(citations omitted). Based on this reading, the court concluded that
``an open dump includes any facility (other than a sanitary landfill or
hazardous waste disposal facility) where solid waste still `is
deposited,' 'is dumped,' `is spilled,' `is leaked,' or `is placed,'
regardless of when it might originally have been dropped off. In other
words, the waste in an inactive impoundment `is disposed of' at a site
no longer receiving new waste in just the same way that it `is disposed
of' at a site that is still operating.'' Id. The court also opined that
``[e]ven if the text were ambiguous, EPA's interpretation is eminently
reasonable under Chevron step two.'' Id. at 442. Judge Henderson wrote
separately and concluded that ``the text--and more precisely, the
grammatical structure--of RCRA's definition of `open dump' is
temporally ambiguous'' and that EPA's interpretation of its authority
to regulate inactive units was a reasonable interpretation of that
ambiguity under Chevron step two. Id. at 451 (Henderson, J., concurring
in part and concurring in the judgment).
EPA requests comment on whether, in light of the court's opinion in
the USWAG decision, the Agency has the discretion to reinterpret the
extent of its authority under RCRA subtitle D. See Nat'l Cable &
Telecommunications
[[Page 65018]]
Ass'n v. Brand X internet Servs., 545 U.S. 967, 981 (2005). If EPA has
the discretion to revisit its interpretation (including potentially
identifying an alternative basis for not regulating inactive surface
impoundments at inactive facilities (``legacy CCR surface
impoundments'') while addressing the court's concern about risk), EPA
requests comment on whether (and, if so, why) it should interpret its
authority, whether for technical and policy reasons or for other
reasons, to extend only to units that were in operation after November
1980 or to some other smaller set of units. If EPA does not revisit the
extent of its authority to regulate inactive units, EPA requests
comment on how far back in time it should reach and whether EPA should
regulate units differently based on when they became inactive. In
addition, EPA requests comment as to whether EPA's regulation of
inactive units should be limited to only units at former power plants
that sold electric power to the grid or whether it should also reach
units at former power plants that provided power to a single site or
facility. EPA generally requests comment on the technical, policy, and
legal rationales for any distinctions that commenters believe it is
appropriate for EPA to draw in this area or with respect to other
topics that are subject to this advance notice of proposed rulemaking.
B. Definition
EPA is considering several options to define a legacy CCR surface
impoundment. For example, EPA could define a legacy CCR surface
impoundment as:
A surface impoundment that is located at a power plant that ceased
generating power prior to October 19, 2015 and
Option 1--the surface impoundment contained both CCR and
liquids on the effective date of the 2015 CCR rule (i.e., October 19,
2015); or
Option 2--the surface impoundment contained both CCR and
liquids on the date the Court issued its mandate for the August 21,
2018 court decision (i.e., October 15, 2018); or
Option 3--the surface impoundment contains both CCR and
liquids on the date EPA issues a final rule bringing legacy CCR surface
impoundments under the federal regulations.
EPA is specifically requesting comment on these options for the
definition of legacy CCR surface impoundments. EPA provided three
options for the definition of legacy CCR surface impoundment because
the Agency is soliciting comment from the public on which option is
best for this newly regulated universe and when such units contained
both CCR and liquids. EPA does not have an estimated number of units
that would be classified under each definition option at this time.
Furthermore, EPA requests comment on how the current owner of the
legacy CCR surface impoundment should be defined. In particular, should
there be a definition of innocent owner that would exclude certain
qualifying landowners from regulation? If so, what should be the
criteria? Should, for example, criteria be based on, or similar to, the
criteria for the landowner liability protections under the
Comprehensive Environmental Response, Compensation, and Liability Act
(CERCLA), commonly known as Superfund, see, https://www.epa.gov/enforcement/landowner-liability-protections#ild? To the extent that
certain landowners are exempted from the CCR rule requiring owners
ensure impoundments meet the national minimum criteria, how should EPA
address the impoundments under their ownership? Relatedly, for this
potential subset of impoundments and for other, abandoned impoundments
that may still contain CCR and liquids, but do not have an identifiable
owner/operator, or for impoundments whose ownership has been
transferred, should EPA evaluate other authorities, (such as CERCLA),
or state programs, to address those units?
C. Size of Universe
The USWAG decision referenced a database that identifies legacy
ponds and their owners that was included in the Regulatory Impact
Analysis supporting EPA's Proposed RCRA Regulation of Coal Combustion
Residues.\4\ Upon further examination, it appears that these data
include all the units that the Agency could identify at the time, not
just inactive surface impoundments at inactive facilities.
---------------------------------------------------------------------------
\4\ A copy of Information Request Responses from Electric
Utilities (April 30, 2010) is available in the docket to this
action.
---------------------------------------------------------------------------
EPA is requesting information on any known inactive surface
impoundments at inactive power plants as of the effective date of the
2015 CCR rule, October 19, 2015. For example,
Plant name (or former plant name);
Location;
If known, retirement year of power plant;
If known, status of unit (e.g., still holding water);
If known the year the surface impoundment ceased receipt
of waste and whether the unit has gone through any sort of closure
process;
Any characteristics of the unit (e.g., size, volume); or
Any other available information about the inactive surface
impoundment.
Additionally, should there be a size limitation for legacy CCR
surface impoundments?
Approximately 10 states have reported to EPA that they have
estimated a total of 37 possible legacy CCR surface impoundments within
their states. USWAG, after surveying their members, indicated they know
of 45 units that could possibly be legacy CCR surface impoundments.
Data showing approximately 140 facilities that have been reported to
have one or more CCR units (boilers) retired or gone out of service
between January of 1993 and October of 2015 were provided to EPA by the
Department of Energy (DOE).\5\ Those facilities are assumed to be
closed because they do not have publicly accessible websites posted as
required by the 2015 CCR rule. Some of these facilities may have been
small power plants that did not generate electricity (or electricity
and heat) for sale to the public, so any impoundments at those
facilities would not be covered under 40 CFR part 257, subpart D.
However, EPA could determine to expand the definition of legacy CCR
surface impoundment to cover small power plant facilities that did not
generate electricity for the sale to the public. However, CCR surface
impoundments (if they exist) at the other facilities could potentially
be considered legacy CCR surface impoundments.
---------------------------------------------------------------------------
\5\ These data are from DOE's contractor, Energy Ventures
Analysis, as of March 1, 2019. A copy of ``DOE-Energy Ventures
Analysis Coal Unit Retirements--Historical + Announced March 1,
2019'' is available in the docket for this rulemaking.
---------------------------------------------------------------------------
In this same DOE database, approximately 110 coal units were listed
as retired or otherwise not burning coal but are located at facilities
that have posted a publicly accessible website containing CCR
compliance data and information. Given the existence of those websites,
any potential surface impoundments at facilities with closed units
would already be regulated as inactive impoundments at active
facilities and would not be considered legacy CCR surface impoundments.
D. Applicable Regulations and Time To Come Into Compliance
The Agency specifically requests comment on which of the
requirements of the 2015 CCR rule should apply to legacy CCR surface
impoundments and
[[Page 65019]]
whether other new requirements should apply to legacy CCR surface
impoundments. EPA has tentatively identified certain requirements from
the 2015 CCR rule that should apply to legacy CCR surface impoundments.
For instance, the establishment of a publicly accessible CCR
website(s) by the companies or States may be appropriate to give the
Agency and public the ability to track groundwater monitoring and
closure progress for these units. The 2015 CCR rule requires that
owners and operators of CCR units establish a publicly accessible
internet site where they are required to post compliance information.
The posting requirements include, for example, compliance information
related to location restrictions, type of liner system, surface
impoundment structural integrity information including hazard potential
classification structural stability and safety factor assessments,
fugitive dust control plans and annual reports, run-on and run-off
controls for landfills, hydrologic and hydraulic capacity plans for
surface impoundments, periodic inspections of CCR units, groundwater
monitoring information including the annual groundwater monitoring and
corrective action reports, and information related to closure or
retrofit of a CCR unit and post-closure care. EPA is also interested in
any potential liabilities associated with generating and maintaining a
public website by owners or operators and local governments.
Also, because the Agency anticipates that many or all legacy CCR
surface impoundments will be found to be unlined, and thus will be
required to close, the groundwater monitoring, corrective action,
closure and post-closure care requirements would be appropriate. EPA is
requesting comment on who should be responsible for complying with
existing requirements such as groundwater monitoring, corrective
action, closure and post-closure care requirements.
Another technical requirement that may be appropriate for legacy
CCR surface impoundments would be the fugitive dust requirements. This
is because CCR could become airborne during closure of the unit and
thus effectively minimizing releases would be appropriate.
However, some CCR rule requirements may not be necessary to apply
to legacy CCR surface impoundments given that the legacy surface
impoundments are no longer receiving waste. For example, certain
location restrictions demonstrations (e.g., whether the legacy surface
impoundment is located in a fault area or seismic impact zone) may not
be a necessary requirement for unlined legacy CCR surface impoundments
because unlined surface impoundments would likely be subject to a
requirement to close.
Another CCR rule requirement that may not be warranted for unlined
legacy CCR surface impoundments is the provision to provide specific
design and construction information pertaining to the CCR unit. One
example in this provision is to provide area-capacity curves for the
CCR unit, which show the reservoir water surface area at different
water levels and the volume of the water contained in the unit at these
different water elevations. It may not be warranted to require owners
of legacy CCR surface impoundments to expend resources to compile this
information for units likely to be subject to closure.
There may be additional standards or controls that are not required
under the 2015 CCR rule that may be appropriate for legacy CCR surface
impoundments. For instance, the posting of general information on the
legacy CCR surface impoundment such as size, location, applicable state
requirements, plant information, etc., could be useful.
The Agency could also consider a site security requirement for the
facility to restrict access to the area containing the legacy CCR
surface impoundment, since active facilities generally have guards and
fencing. The Agency solicits comment on which additional standards or
controls may be appropriate for legacy CCR surface impoundments.
In addition, EPA will need to determine the compliance deadlines
for CCR surface impoundment regulations. The Agency would likely
consider that a publicly accessible website would be required to be
activated by the effective date of the rule. For other requirements,
the Agency could base the timing on the timeline laid out in the 2015
CCR rule or from subsequent CCR rulemakings,\6\ \7\ \8\ allowing
approximately the same amount of time for legacy CCR surface
impoundments to come into compliance as the active CCR surface
impoundments. However, the timeline specified in the 2015 CCR rule was
based in part on the owner or operator of the unit having to go through
a series of steps to determine if the unit would be required to close.
In the case of unlined inactive CCR surface impoundments at inactive
facilities, it may be reasonable to assume that some owners and
operators of these units have known that they may need to close such
units since October 15, 2018 (i.e., the date the Court issued its
mandate for the August 21, 2018 USWAG decision). Because of this, and
because neither the unit nor the power plant are operating, some owners
and operators may have begun preparing for closure and thus could close
in less time than was EPA has provided for active surface impoundments.
The Agency specifically requests comment on the issue of appropriate
compliance deadlines for the applicable requirements for legacy CCR
surface impoundments. In addition, EPA is requesting comment on the
establishment of publicly accessible websites, and specifically seeking
input of who should establish and host the website, such as an owner or
operator, a state or local government, or EPA.

In cases where significant vegetation or sensitive ecosystems are
in place, should EPA take into account the impacts of disrupting that
ecosystem when determining what actions should be imposed? Can the
agency simply require notice and no further action under some
circumstances? If so, what would those be, and why?
V. Request for Comment and Additional Information
EPA is seeking comment on all questions and topics described in
this ANPRM, including the questions and issues identified in Unit IV,
and requests that you submit any information, which may not be included
in this document, that you believe is important for EPA to consider in
connection with these questions and topics. At the same time, EPA does
not plan to consider comments that are beyond the scope of the
questions and topics described in this ANPRM.
Instructions for providing written comments are provided under
ADDRESSES, including how to submit any comments that contain CBI.
VI. What are the next steps EPA will take?
EPA intends to carefully review all the comments and information
received in response to this ANPRM. Once that review is completed, EPA
may supplement the collected information, as appropriate, to determine
which regulatory criteria should apply to legacy CCR surface
impoundments. The next step will be to submit an information collection
request to OMB, or if EPA determines that additional information is not
needed, EPA will publish a proposed rule with the input from this ANPRM
and other publicly available information. The anticipated date for
issuing the proposed rule is July 2021. At that time, the public will
have
[[Page 65020]]
the opportunity to comment on EPA's proposal.
VII. Statutory and Executive Order Reviews
Under Executive Order 12866 (58 FR 51735, October 4, 1993) and
Executive Order 13563 (76 FR 3821, January 21, 2011), this action was
submitted to the Office of Management and Budget (OMB) for review. Any
changes made in response to OMB recommendations have been documented in
the docket for this action. Because this action does not impose or
propose any requirements, and instead seeks comments and suggestions
for the Agency to consider in possibly developing a subsequent proposed
rule, other statutory and Executive Order reviews that apply to
rulemaking do not apply to this action. Should EPA subsequently
determine to pursue a rulemaking, EPA will address the statutes and
Executive Order as applicable to the rulemaking.
Nevertheless, the Agency welcomes comments and/or information that
would help the Agency to assess any of the following: The potential
impact of a rule on small entities pursuant to the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et seq.); potential impacts on
federal, state, or local governments pursuant to the Unfunded Mandates
Reform Act ((UMRA) (2 U.S.C. 1531-1538); federalism implications
pursuant to Executive Order 13132, entitled Federalism (64 FR 43255,
November 2, 1999); availability of voluntary consensus standards
pursuant to section 12(d) of the National Technology Transfer and
Advancement Act of 1995 (NTTAA), Public Law 104-113; tribal
implications pursuant to Executive Order 13175, entitled Consultation
and Coordination with Indian Tribal Governments (65 FR 67249, November
6, 2000); environmental health or safety effects on children pursuant
to Executive Order 13045, entitled Protection of Children from
Environmental Health Risks and Safety Risks (62 FR 19885, April 23,
1997); energy effects pursuant to Executive Order 13211, entitled
Actions Concerning Regulations that Significantly Affect Energy Supply,
Distribution, or Use (66 FR 28355, May 22, 2001); Paperwork burdens
pursuant to the Paperwork Reduction Act (PRA) (44 U.S.C. 3501); or
human health or environmental effects on minority or low-income
populations pursuant to Executive Order 12898, entitled Federal Actions
to Address Environmental Justice in Minority Populations and Low-Income
Populations (59 FR 7629, February 16, 1994). The Agency will consider
such comments during the development of any subsequent proposed
rulemaking.
