ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 52
[EPA-R01-OAR-2020-0255; FRL-10011-23-Region 1]
Air Plan Approval; Connecticut; Control of Particulate Matter
and Visible Emissions
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve a State Implementation Plan (SIP) revision submitted by the
State of Connecticut. This revision amends a Connecticut air-quality
regulation for controlling particulate matter (PM) and visible
emissions. The intended effect of this action is to define the process
industries and activities to which this regulation applies, and to make
technical corrections to an emission-rate calculation method. This
action is being taken under the Clean Air Act.
DATES: Written comments must be received on or before July 29, 2020.
ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R01-
OAR-2020-0255 at https://www.regulations.gov, or via email to

I. Background and Purpose
On October 19, 2018, the Connecticut Department of Energy and
Environmental Protection (DEEP) submitted a revision to its State
Implementation Plan (SIP) for amendments to Regulations of Connecticut
State Agencies (RCSA) section 22a-174-18, Control of particulate matter
(PM) and visible emissions. The revision consists of amendments to
subsections (c), (f), and (j) to define the process industries and
activities to which this regulation applies, to make technical
corrections to an emission-rate calculation method, and to make minor,
non-substantive modifications in regulatory language.
II. EPA's Evaluation of Connecticut's Regulation
Background
Connecticut first adopted regulations to limit PM and visible
emissions from stationary sources, including among other sources,
electric generating units (EGUs) and boilers, in the early 1970s. In
1972, EPA approved ``Control of particulate emissions,'' into the
Connecticut SIP. See 37 FR 10842. That regulation has since been
recodified as Regulations of Connecticut State Agencies (RCSA) section
22a-174-18.
The most recent amendments to section 22a-174-18 were submitted by
CT DEEP on December 1, 2004 and approved into the Connecticut SIP on
July 16, 2014. See 79 FR 41427. Those amendments updated the State's
visible emissions standards. Details of the State's December 2004 SIP
submittal and the rationale for EPA's approval are explained in the
August 15, 2013, notice proposed of rulemaking (NPRM). See 78 FR 49701.
See Section II of that NPRM for a brief discussion of the relationships
among ``visible emissions,'' ``opacity'' and ``particulate matter.''
2018 Amendments to RCSA Section 22a-174-18
On October 19, 2018, Connecticut submitted to EPA revisions to RCSA
section 22a-174-18. These revisions, which became effective in
Connecticut on August 3, 2018, consist of revisions to subsections (c),
(f), and (j) of RCSA section 22a-174-18 regarding the control of
emissions of particulate matter from process industries. The revisions
modify language and correct errors in the State's 2004 revision of RCSA
section 22a-174-18, which was approved by EPA on July 16, 2014. See 79
FR 41427.
Specifically, the revisions clarify the types of industrial
activities regulated by subsection (f) by adding a definition of
``process industry'' in subsection (f).\1\ The revisions also simplify
the method used in subsection (f) to calculate the allowable emission
rate for process industries, clarify in subsection (c) that process
industries subject to subsection (f) are not subject to subsection (c),
and make minor, non-substantive changes in language to subsection
(j).\2\
---------------------------------------------------------------------------
\1\ The definition of ``process industry'' is given as ``a
business that is primarily concerned with processing of bulk
material into other products.'' The revisions also define ``bulk
material'' as dry material, such as, but not limited to, ore, coal,
cereal, wood, sand, gravel or stone in loose, bulk form.''
\2\ We note that as a matter of state law, Connecticut has also
removed certain language from subsections (j)(1) and (2) in order to
conform state law to the existing SIP. The removal of such language
as a matter of state law has no impact on the Connecticut SIP or
this action.
---------------------------------------------------------------------------
EPA has determined that Connecticut's revisions to RCSA section
22a-174-18 are clarifications and corrections that improve the State's
ability to implement the regulation. In addition, the submitted
revisions to subsection (j) are non-substantive (e.g., changing
``subdivision'' to ``subsection''). These revisions do not
[[Page 38831]]
result in any substantive change to the EPA-approved subsection (j).
Therefore, EPA proposes to approve into the Connecticut SIP the
revisions to subsections (c), (f), and (j) that CT DEEP submitted on
October 19, 2018.
III. Proposed Action
EPA is proposing to approve, and incorporate into the Connecticut
SIP, the revisions to subsections (c), (f), and (j) of RCSA section
22a-174-18, Control of Particulate Matter and Visible Emissions,
effective on August 3, 2018, submitted to EPA on October 19, 2018.
EPA is soliciting public comments on the issues discussed in this
notice or on other relevant matters. These comments will be considered
before taking final action. Interested parties may participate in the
Federal rulemaking procedure by submitting written comments to this
proposed rule by following the instructions listed in the ADDRESSES
section of this Federal Register.
IV. Incorporation by Reference
In this rule, the EPA is proposing to include in a final EPA rule
regulatory text that includes incorporation by reference. In accordance
with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by
reference into the Connecticut SIP the Connecticut regulation
referenced in Section III above. The EPA has made, and will continue to
make, these documents generally available through https://www.regulations.gov and at the EPA Region 1 Office (please contact the
person identified in the FOR FURTHER INFORMATION CONTACT section of
this preamble for more information).
V. Statutory and Executive Order Reviews
Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Act and
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act.
Accordingly, this proposed action merely approves state law as meeting
Federal requirements and does not impose additional requirements beyond
those imposed by state law. For that reason, this proposed action:
Is not a significant regulatory action subject to review
by the Office of Management and Budget under Executive Orders 12866 (58
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
Is not expected to be an Executive Order 13771 regulatory
action because this action is not significant under Executive Order
12866;
Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
Does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
Does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the Clean Air Act; and
Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).
In addition, the SIP is not approved to apply on any Indian
reservation land or in any other area where EPA or an Indian tribe has
demonstrated that a tribe has jurisdiction. In those areas of Indian
country, the rule does not have tribal implications and will not impose
substantial direct costs on tribal governments or preempt tribal law as
specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
