Abstract
The Environmental Protection Agency (EPA) is approving a portion of the state implementation plan (SIP) revisions submitted by the Commonwealth of Pennsylvania. The revisions being approved adopt nitrogen oxides (NO<INF>X</INF>) emission limits and requirements for the coal-fired electric generating units (EGUs) equipped with selective catalytic reduction (SCR) at the Keystone, Conemaugh, Homer City, and Montour facilities. The NO<INF>X</INF> limits address reasonably available control technology (RACT) requirements for these EGUs for the 1997 and 2008 ozone national ambient air quality standards (NAAQS) and address the deficiencies identified in EPA's August 16, 2022, disapproval of an earlier SIP submission. This action is being taken under the Clean Air Act (CAA).

AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is approving a
portion of the state implementation plan (SIP) revisions submitted by
the Commonwealth of Pennsylvania. The revisions being approved adopt
nitrogen oxides (NO<INF>X</INF>) emission limits and requirements for
the coal-fired electric generating units (EGUs) equipped with selective
catalytic reduction (SCR) at the Keystone, Conemaugh, Homer City, and
Montour facilities. The NO<INF>X</INF> limits address reasonably
available control technology (RACT) requirements for these EGUs for the
1997 and 2008 ozone national ambient air quality standards (NAAQS) and
address the deficiencies identified in EPA's August 16, 2022,
disapproval of an earlier SIP submission. This action is being taken
under the Clean Air Act (CAA).
DATES: This final rule is effective on December 6, 2024.

SUPPLEMENTARY INFORMATION:
I. Background
On August 16, 2022, (87 FR 50257) EPA took final action to
disapprove portions of a Pennsylvania SIP revision submitted May 16,
2016 that, among other things, established NO<INF>X</INF> emission
limitations for the coal-fired EGUs equipped with SCR at the Keystone,
Conemaugh, Homer City, and Montour facilities, to satisfy certain RACT
obligations for the 1997 and 2008 ozone NAAQS.\1\ EPA's August 16,
2022, final disapproval started a sanctions clock under CAA section 179
and 40 CFR 52.31. The two-to-one new source emissions offset sanction
took effect on March 15, 2024 (18 months following the September 15,
2022, effective date of the August 16, 2022, disapproval, 87 FR 50257).
Highway funding sanctions would have taken effect September 15, 2024,
unless the state submitted, and EPA approved, SIP revisions correcting
the deficiencies identified in the August 16, 2022, disapproval action.
---------------------------------------------------------------------------
\1\ A more detailed and complete summary of the history of the
RACT limits for these EGUs can be found in the Notice of Proposed
Rulemaking for this final action. 89 FR 56680 (July 10, 2024).
---------------------------------------------------------------------------
On August 31, 2022, EPA issued a Federal implementation plan (FIP)
adopting NO<INF>X</INF> RACT limits for these four sources addressing
these same RACT obligations. 87 FR 53381. Three of the sources subject
to the FIP filed a challenge to the FIP in the U.S. Third Circuit Court
of Appeals. Keystone-Conemaugh Projects LLC v. EPA, et al., No. 22-
3026. Following briefing and oral argument, on May 2, 2024, the Third
Circuit issued a decision upholding the RACT limits and other
requirements in EPA's August 31, 2022, FIP. The court decided and
resolved all issues raised by the Petitioners in EPA's favor. Id.
On April 10, 2024, Pennsylvania Department of Environmental
Protection (PADEP) submitted two SIP revisions to
[[Page 87956]]
EPA which adopted into the SIP the NO<INF>X</INF> limits and other
requirements found in EPA's final August 31, 2022, FIP for Keystone,
Conemaugh, Homer City, and Montour (Montour was submitted separately).
On July 10, 2024, EPA published a notice of proposed rulemaking (NPRM)
proposing to approve Pennsylvania's April 10, 2024, SIP revisions (89
FR 56680). EPA's NPRM also proposed to find that the incorporation of
title V permits containing the FIP requirements into Pennsylvania's SIP
addressed the deficiencies identified in EPA's August 16, 2022 (87 FR
50257), partial disapproval. The reasons for the proposed approval and
the determination were stated in the proposal for this action and will
not be restated here. Based on this finding and the proposed approval,
EPA simultaneously issued an Interim Final Determination (IFD) staying
the application of the offset sanction and deferring the application of
the highway sanction triggered by EPA's August 16, 2022 (87 FR 50257)
disapproval. 89 FR 56666 (July 10, 2024). EPA's proposed action noted
that it was not taking action at this time on certain RACT limits for
auxiliary boilers which were included in the SIP revisions, and
therefore this final action does not address those RACT limits for the
identified auxiliary boilers.
The public comment period for the proposed approval and
determination ended on August 9, 2024. EPA received three comments,
which can be found in the docket. One of the comments is not relevant
to this action and will not be addressed. The other two were
supportive, but one generally supportive comment also contained
comments which could be considered adverse. Those potentially adverse
comments are addressed below.
II. Summary of SIP Revision and EPA Analysis
Pennsylvania's SIP submissions, dated April 9, 2024, and received
by EPA on April 10, 2024, included four redacted title V permits
incorporating the FIP requirements for the EGUs equipped with SCR at
Keystone, Conemaugh, Homer City, and Montour. EPA has reviewed these
permits and determined that the permits incorporate the same emission
limits, monitoring, testing, recordkeeping, reporting, work practices
and other requirements for these EGUs found in EPA's FIP. The permits
are listed in Table 1 in this document. These submissions and permits
are part of the docket for this rule making and are available online at
<a href="http://www.regulations.gov">www.regulations.gov</a>.
Table 1--List of Title V permits incorporating the Requirements of the August 31, 2022, Federal Implementation
Plan

----------------------------------------------------------------------------------------------------------------
The title V permits in the April 10, 2024, SIP submissions for
Keystone and Conemaugh also contain case-by-case RACT limits for
certain gas or oil-fired auxiliary boilers at these facilities.
However, EPA is not taking action at this time on the case-by-case RACT
limits in these permits for two auxiliary boilers at Keystone (Source
IDs 037 and 038) and two at Conemaugh (Source IDs 039 and 041). These
auxiliary boilers were not subject to the presumptive RACT limit in 25
Pa. Code 129.97(g)(1)(viii) for which EPA issued a final disapproval in
August 2022.
As explained in the proposed action, EPA's assessment regarding the
approvability of the RACT limits and other requirements for these EGUs
found in Pennsylvania's SIP submission is substantially the same as the
justification and analysis in the record EPA created for its FIP. EPA
provided an in-depth discussion of the methodology and reasoning for
setting the FIP limits for each of these EGUs in EPA's proposed FIP (87
FR 31798, May 25, 2022), the associated technical support document
supporting the proposed FIP, and in responses to comments received on
the proposed FIP and published with the final FIP action (87 FR 53381,
August 31, 2022). EPA has put the technical support document for EPA's
FIP into the docket for this action. The Federal Register documents for
the proposed and final FIP are available at <a href="http://www.regulations.gov">www.regulations.gov</a> under
docket number EPA-R03-OAR-2022-0347 and in the Federal Register at the
citations provided in the prior sentence. EPA is not aware of any
change in the facts since the FIP was finalized that would alter any of
the limits or requirements or EPA's analysis supporting the FIP. Other
specific requirements of Pennsylvania's April 10, 2024, submittal and
the rationale for EPA's proposed action are explained in the NPRM and
will not be restated here.
III. EPA's Response to Comments Received
EPA received three comments on the July 10, 2024, documents. One
comment is not relevant to this action and will not be addressed. A
summary of the other two comments and EPA's responses follow. Copies of
all the comments are in the docket for this rule action.
Comment 1: The commenter first acknowledges some key historical
developments concerning the NO<INF>X</INF> RACT requirements for the
Keystone and Conemaugh EGUs, including PADEP's prior SIP submission of
May 26, 2022, EPA's proposed disapproval of that SIP submission,
PADEP's withdrawal of that SIP submission following EPA's proposed
disapproval, and the May 2, 2024, decision by the Third Circuit Court
of Appeals upholding the RACT limits and other requirements in EPA's
August 31, 2022, FIP. The commenter then states that they ``[support]
the EPA's effort to finalize the SIP as prepared by the PADEP.''
The commenter then notes that ``the challenges of operating under
these limits that KEY-CON noted during the rulemaking process for the
FIP remain.'' The commenter asserts that in order to account for start-
up events where higher NO<INF>X</INF> emissions above the limit are
unavoidable, the sources must operate at a target NO<INF>X</INF>
emission rate that is lower than each sources' limit. The commenter
acknowledges that ``operating in this manner provides a manageable
balance for maintaining an adequate (but small) margin of compliance
and limiting excessive aqueous ammonia injection rates that are
required to achieve lower NO<INF>X</INF> emission rates.'' The comment
notes that extended periods of excessive ammonia injection can lead to
fouling of the air preheaters, and that this problem is exacerbated in
colder weather. As a result, the commenter states that the
[[Page 87957]]
frequency of conducting heater washes, as well as SCR reactor
maintenance, has increased, and that the limits in the proposed
rulemaking ``are at the very bounds of our NO<INF>X</INF> emissions
control capability.''
Response 1: EPA thanks the commenter for their largely supportive
comment, and agrees that PADEP's April 10, 2024, SIP revision
incorporating the NO<INF>X</INF> limits from EPA's FIP should be
finally approved and incorporated in the Pennsylvania SIP to meet
certain RACT requirements for these sources for the 1997 and 2008 Ozone
NAAQS. The commenter's concerns regarding fouling of the air preheaters
with ammonium bisulfate (ABS) under certain conditions and the need for
increased maintenance to address this fouling are similar to those
contained in the commenter's July 11, 2022, comments on EPA's proposed
FIP. EPA addressed those comments in the final rule adopting the FIP
limits. See 87 FR 53381, at 53390 and 53391, August 31, 2022. However,
the commenter now goes on to state that the current limits and other
requirements provide ``a manageable balance for maintaining an adequate
(but small) margin of compliance.'' EPA agrees that this balance is
appropriate in light of the longstanding definition of RACT as ``the
lowest emission limitation that a particular source is capable of
meeting by the application of control technology that is reasonably
available considering technological and economic feasibility.'' \2\
Table 2, in this preamble are citations to the specific places in the
final rule approving the FIP limit where EPA responded to similar
concerns expressed by the commenter.

------------------------------------------------------------------------
In addition to the above concerns, the commenter expresses concern
that in the future, more restrictive limits might be placed on these
units in order to meet RACT requirements for the 2015 ozone NAAQS.
Although Pennsylvania has adopted regulations setting RACT limits for
certain major sources of VOCs and NO<INF>X</INF> (See 25 Pa. Code
129.111--129.115) for the 2015 ozone NAAQS, those regulations do not
set NO<INF>X</INF> limits for coal-fired EGUs equipped with SCR. When
PADEP develops case-by-case RACT limits for the commenter's sources and
submits them to EPA for approval as a SIP revision, there will be
another opportunity for the commenter to share information on whether
any new but lower NO<INF>X</INF> limits are technologically and
economically feasible.
Comment 2: The commenter states:
I am writing to provide comments on the interim final
determination to stay and defer sanctions related to the Reasonably
Available Control Technology (RACT) requirements for the Keystone,
Conemaugh, Homer City, and Montour generating facilities in
Pennsylvania under the 1997 and 2008 Ozone National Ambient Air
Quality Standards (NAAQS). While the intent of deferring sanctions
might be to allow time for compliance, there are critical aspects
that need to be carefully considered. It is essential that the
control measures adopted for these facilities are strict and in line
with the most current technologies and practices. The stay should
not compromise the effectiveness of RACT in reducing emissions.
Adequate and enforceable measures must be established to achieve the
required air quality improvements and standards. There should be
procedures and rules such facilities are monitored and held
accountable for their actions to ensure that facilities are taking
substantive steps toward compliance. There should be regular reports
to ensure everything is going smoothly.
Response 2: EPA agrees that it is essential that control measures
adopted for these facilities be strict and in line with current
technologies and practices, so long as those technologies and practices
meet the definition of RACT. EPA's longstanding definition of RACT is
``the lowest emission limitation that a particular source is capable of
meeting by the application of control technology that is reasonably
available considering technological and economic feasibility.'' \3\ EPA
also agrees that the RACT limits must be accompanied by enforceable
measures, appropriate monitoring, recordkeeping, and reporting to
ensure compliance. EPA believes that the requirements of its FIP, and
this SIP revision adopting the same FIP requirements, achieve RACT
levels of control and provide the necessary monitoring, recordkeeping,
and reporting needed to ensure enforcement of the limits. EPA also
notes that the RACT limits and other requirements for these sources
have been enforceable since March 29, 2023, which was the initial
compliance date for the limits set forth in the FIP issued by EPA on
September 30, 2022. 87 FR 53381. Regarding the IFD, EPA notes that the
IFD only stayed the application of the offset sanction and deferred the
application of the highway funding sanctions. The IFD does not in any
way impact the RACT requirements the facilities must meet in the FIP.

IV. Final Action
EPA is approving Pennsylvania's April 10, 2024, SIP revision to the
Pennsylvania SIP, with the exception of certain RACT limits for
auxiliary boilers, as set forth in EPA's NPRM. In addition, EPA is
determining that Pennsylvania's April 10, 2024, SIP revision addressed
the deficiencies identified in EPA's August 16, 2022 (87 FR 50257)
partial disapproval. Finalization of this approval permanently stops
the offset sanctions which took effect on March 15, 2024, and prevents
the imposition of highways sanctions which could have taken effect on
September 15, 2024.
[[Page 87958]]
V. Incorporation by Reference
In this document, EPA is finalizing regulatory text that includes
incorporation by reference. In accordance with requirements of 1 CFR
51.5, EPA is finalizing the incorporation by reference of source-
specific RACT determinations and alternative NO<INF>X</INF> emissions
limits under the 1997 and 2008 8-hour ozone NAAQS for certain major
sources of NO<INF>X</INF> in Pennsylvania described in section II. of
this preamble and as set for the below in the amendments to 40 CFR part
52. EPA has made, and will continue to make, these materials generally
available through <a href="http://www.regulations.gov">www.regulations.gov</a> and at the EPA Region III Office
(please contact the person identified in the FOR FURTHER INFORMATION
CONTACT section of this preamble for more information). Therefore,
these materials have been approved by EPA for inclusion in the SIP,
have been incorporated by reference by EPA into that plan, are fully
federally enforceable under sections 110 and 113 of the CAA as of the
effective date of the final rule of EPA's approval, and will be
incorporated by reference in the next update to the SIP compilation.\4\
---------------------------------------------------------------------------
\4\ 62 FR 27968 (May 22, 1997).
---------------------------------------------------------------------------
VI. Statutory and Executive Order Reviews
A. General Requirements
Under the CAA, the Administrator is required to approve a SIP
submission that complies with the provisions of the CAA 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 CAA. Accordingly, this
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 action:
<bullet> 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);
<bullet> Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
<bullet> 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.);
<bullet> 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);
<bullet> Does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
<bullet> Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
<bullet> Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001); and
<bullet> 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;
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).
Executive Order 12898 (Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations, 59 FR 7629,
February 16, 1994) directs Federal agencies to identify and address
``disproportionately high and adverse human health or environmental
effects'' of their actions on minority populations and low-income
populations to the greatest extent practicable and permitted by law.
EPA defines environmental justice (EJ) as ``the fair treatment and
meaningful involvement of all people regardless of race, color,
national origin, or income with respect to the development,
implementation, and enforcement of environmental laws, regulations, and
policies.'' EPA further defines the term fair treatment to mean that
``no group of people should bear a disproportionate burden of
environmental harms and risks, including those resulting from the
negative environmental consequences of industrial, governmental, and
commercial operations or programs and policies.''
The Pennsylvania Department of Environmental Protection did not
evaluate environmental justice considerations as part of its SIP
submittal; the CAA and applicable implementing regulations neither
prohibit nor require such an evaluation. EPA did not perform an EJ
analysis and did not consider EJ in this action. Due to the nature of
the action being taken here, this action is expected to have a neutral
to positive impact on the air quality of the affected area.
Consideration of EJ is not required as part of this action, and there
is no information in the record inconsistent with the stated goal of
E.O. 12898 of achieving environmental justice for people of color, low-
income populations, and Indigenous peoples.
B. Submission to Congress and the Comptroller General
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. Section 804, however, exempts from section 801 the
following types of rules: Rules of particular applicability; rules
relating to agency management or personnel; and rules of agency
organization, procedure, or practice that do not substantially affect
the rights or obligations of non-agency parties. 5 U.S.C. 804(3).
Because this is a rule of particular applicability, EPA is not required
to submit a rule report regarding this action under section 801.
C. Petitions for Judicial Review
Under section 307(b)(1) of the CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by January 6, 2025. Filing a petition for
reconsideration by the Administrator of this final rule does not affect
the finality of this action for the purposes of judicial review nor
does it extend the time within which a petition for judicial review may
be filed and shall not postpone the effectiveness of such rule or
action. This action addressing the NO<INF>X</INF> RACT requirements for
EGUs equipped with SCR at the Keystone, Conemaugh, Homer City and
Montour facilities for the 1997 and 2008 Ozone NAAQS may not be
challenged later in proceedings to enforce its requirements. (See
section 307(b)(2).)
