ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is approving a State 
Implementation Plan (SIP) revision submitted by the State of Montana on 
March 25, 2020, addressing regional haze. Specifically, EPA is 
approving a SIP revision for the first implementation period of the 
Clean Air Act's (CAA) regional haze program that addresses the nitrogen 
oxides (NOX) and sulfur dioxide (SO2) Best 
Available Retrofit Technology (BART) requirements for two electric 
generating unit (EGU) facilities, as well as replaces portions of the 
Federal Implementation Plan (FIP) promulgated by EPA in 2012 (2012

regional haze FIP) addressing the NOX, SO2, and 
particulate matter (PM) BART requirements for two cement kilns and the 
PM BART requirements for the same two EGU facilities. Consistent with 
our approval of Montana's regional haze SIP revision, EPA is 
withdrawing, the portions of the FIP promulgated by EPA in the 2012 
regional haze FIP addressing the NOX, SO2, and PM 
BART requirements for the two cement kilns and the PM BART requirements 
for the two EGU facilities. This action also addresses the United 
States Court of Appeals for the Ninth Circuit's June 9, 2015 vacatur 
and remand of portions of the FIP. EPA is finalizing this action 
pursuant to the CAA.

DATES: This rule is effective on July 26, 2023.

ADDRESSES: The EPA has established a docket for this action under 
Docket ID No. EPA-R08-OAR-2021-0001. All documents in the docket are

I. Background

    In our notice of proposed rulemaking published on September 9, 2022 
(87 FR 55331), EPA proposed to approve revisions to Montana's regional 
haze SIP submitted by the State of Montana on March 25, 2020. In this 
rulemaking, we are taking final action to approve two Montana Board of 
Environment Review Orders pertaining to regional haze requirements for 
four facilities \1\ into the state's SIP. Specifically, EPA is 
approving: (1) NOX, SO2, and PM BART emission 
limits along with associated requirements for the Ash Grove Cement 
Company's Montana City Plant (Montana City) and GCC Three Forks, LLC's 
Trident Plant (Trident); (2) the PM BART emission limits along with 
associated requirements for Talen Montana, LLC's Colstrip Steam 
Electric Station, Units 1 and 2 (Colstrip Units 1 and 2); (3) the 
determination that Colstrip Units 1 and 2's enforceable shutdown date 
of July 1, 2022, satisfies the outstanding NOX and 
SO2 BART requirements for that facility; and (4) the 
determination that the outstanding NOX and SO2 
BART requirements for Corette (as well as the remaining PM BART 
requirements for Corette in EPA's FIP) are satisfied because the source 
is no longer in operation and has been demolished.
---------------------------------------------------------------------------

    \1\ Ash Grove Cement Company's Montana City Plant; GCC Three 
Forks, LLC's Trident Plant; JE Corette Steam Electric Station; and 
Talen Montana, LLC's Colstrip Steam Electric Station, Units 1 and 2.
---------------------------------------------------------------------------

    Consistent with our approval of Montana's regional haze SIP for the 
PM BART emission limits and other requirements for Colstrip Units 1 and 
2 and Corette along with the NOX, SO2, and PM 
BART emission limits and other requirements for Montana City and 
Trident, we are also withdrawing those corresponding portions of the 
2012 regional haze FIP found at 40 CFR 52.1396.
    In addition, through our approval of the NOX and 
SO2 BART determinations for Corette and Colstrip Units 1 and 
2, we are addressing the U.S. Court of Appeals for the Ninth Circuit's 
June 9, 2015 remand of portions of the 2012 regional haze FIP in this 
action, including EPA's response to a public comment regarding the use 
of the CALPUFF visibility model in determining BART at Colstrip Units 1 
and 2.
    The technical rationale for our approval and our response to the 
remand of portions of the 2012 FIP for Montana are provided in detail 
in the proposed rule.

II. Public Comments and EPA Responses

    We received two comments that were both submitted anonymously 
during the public comment period. EPA determined that the first 
comment, which asks where money collected in the form of fees, auctions 
of emissions rights, and permits will go, does not pertain to and is 
outside the scope of our proposed action and fails to identify a 
material issue related to this action that necessitates a response. 
Below is a summary of the second comment and EPA's response.
    Comment: The commenter asserts that NOX, SO2, 
and PM are dangerous chemicals that lead to adverse health effects, 
including respiratory infections, asthma, lung disease and cancer. 
Likewise, the commenter claims that these emissions could also cause 
environmental damage, including acid rain, contributions to the 
greenhouse effect, and changes to weather patterns associated with 
climate change. In summary, the commenter argues that these emissions 
are harmful to people living nearby these facilities and reductions in 
emissions will protect both human health and the environment.
    Response: EPA appreciates the commenter's concerns regarding the 
negative health impacts of NOX, SO2, and PM. 
While the legal requirements against which we have evaluated Montana's 
SIP submission for purposes of this action concern remedying visibility 
impairment,\2\ we note this action may also have potential co-benefits 
through the reductions of NOX, SO2, and PM 
emissions associated with meeting the BART requirements. Therefore, 
while we appreciate the commenter's concern and support for this 
action, we take no positions as to these specific statements.

    \2\ See generally CAA section 169A.

III. EPA's Final Action

    We are approving the following elements of Montana's regional haze 
SIP revision as satisfying the applicable requirements for the first 
regional haze planning period:
     In the Matter of an Order Setting Air Pollutant Emission 
Limits that the State of Montana may Submit to the Federal 
Environmental Protection Agency for Revision of the State 
Implementation Plan Concerning Protection of Visibility, Affecting the 
Following Facilities: Ash Grove Cement Company's Montana City Plant, 
and GCC Three Forks, LLC's Trident Plant. Board Order Findings of Fact, 
Conclusions of Law, and Order. October 18, 2019, Appendix A.
     In the Matter of an Order Setting Air Pollutant Emission 
Limits that the State of Montana may Submit to the Federal 
Environmental Protection Agency for Revision of the State 
Implementation Plan Concerning Protection of Visibility, Affecting the 
Following Facilities: Talen Montana, LLC's Colstrip Steam Electric 
Station, Units 1 and 2, and JE Corette Steam Electric Station. Board 
Order Findings of Fact, Conclusions of Law, and Order. October 18, 
2019, Appendix A.
    Because we are finding that Montana's SIP revision satisfies the 
applicable requirements related to the obligation for states' regional 
haze plans to include BART for the first regional haze planning period, 
we are also withdrawing the corresponding portions of the 2012 regional 
haze FIP addressing the NOX, SO2, and PM BART 
emission limits and associated requirements for two cement kilns and 
the PM BART emission limits and associated requirements for the two EGU 
facilities contained within our 2012 regional haze FIP at 40 CFR 
52.1396. While EPA is approving the emission limits, compliance 
determination requirements, and other monitoring, reporting, and 
recordkeeping requirements associated with BART into Montana's SIP as 
detailed in the proposed rule, other regional haze requirements for the 
first implementation period, including requirements related to 
reasonable progress and analytical requirements related to BART remain 
satisfied by EPA's FIP (with no enforceable FIP requirements left in 
the CFR).

IV. Incorporation by Reference

    In this document, EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with the requirements of 1 
CFR 51.5, EPA is finalizing the incorporation by reference of the SIP 
amendments described in section III of this preamble. The EPA has made, 
and will continue to make, these materials generally available through 
https://www.regulations.gov (refer to docket EPA-R08-OAR-2021-0001) and 
at the EPA Region 8 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 rulemaking of EPA's 
approval, and will be incorporated by reference by the Director of the 
Federal Register in the next update to the SIP compilation.\3\

V. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at http://www.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 14094: Modernizing Regulatory Review

    This action is exempt from review under Executive Order 12866, as 
amended by Executive Order 14094, because it applies to only 4 
facilities in the State of Montana.

B. Paperwork Reduction Act

    This action does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act (PRA) because it revises 
the reporting requirements for 4 facilities.

C. Regulatory Flexibility Act

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the Regulatory 
Flexibility Act (RFA). This action will not impose any requirements on 
small entities as no small entities are subject to the requirements of 
this rule.

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or 
more as described in UMRA, 2 U.S.C. 1531-1538, and does not 
significantly or uniquely affect small governments. The action merely 
transfers the regional haze requirements found in the 2012 regional 
haze FIP to a SIP and approves the State's permanent closure of two 
facilities, thus this action is not subject to the requirements of 
sections 202 or 205 of UMRA. This action is also not subject to the 
requirements of section 203 of UMRA because it contains no regulatory 
requirements that might significantly or uniquely affect small 
governments.

E. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have 
substantial direct effects on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175, entitled ``Consultation and Coordination 
with Indian Tribal Governments'', requires EPA to develop an 
accountable process to ensure ``meaningful and timely input by tribal 
officials in the development of regulatory policies that have tribal 
implications.'' \4\ This action does not have tribal implications, as 
specified in Executive Order 13175. It will not have substantial direct 
effects on tribal governments. Thus, Executive Order 13175 does not 
apply to this action. However, EPA did send letters to each of the 
Montana tribes explaining our regional haze action and offering 
consultation.
---------------------------------------------------------------------------

    \4\ 65 FR 67249, 67250 (November 9, 2000).
---------------------------------------------------------------------------

G. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    This action is not subject to Executive Order 13045 (62 FR 19885, 
April 23, 1997). EPA interprets Executive Order 13045 as applying only 
to those regulatory actions that concern environmental health or safety 
risks that EPA has reason to believe may disproportionately affect 
children, per the definition of ``covered regulatory action'' in 
section 2-202 of the Executive Order. This action is not subject to 
Executive Order 13045 because it does not concern an environmental 
health risk or safety risk.

H. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    This action is not subject to Executive Order 13211 (66 FR 28355 
(May 22, 2001)), because it is not a significant

[[Page 41323]]

regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement (NTTAA)

    This rulemaking does not involve technical standards.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898 (59 FR 7629, February 16, 1994) directs 
Federal agencies, to the greatest extent practicable and permitted by 
law, to make environmental justice part of their mission by identifying 
and addressing, as appropriate, disproportionately high, and adverse 
human health or environmental effects of their programs, policies, and 
activities on minority populations (people of color and/or Indigenous 
peoples) and low-income populations.
    The EPA believes that the human health and environmental conditions 
that exist prior to this action do not result in disproportionate and 
adverse effects on people of color, low-income populations, and/or 
Indigenous peoples. In 2012, we determined that our final action would 
``not have disproportionately high and adverse human health or 
environmental effects on minority or low-income populations because it 
increased the level of environmental protection for all affected 
populations without having any disproportionately high and adverse 
human health or environmental effects on any population, including any 
minority or low-income population.'' \5\
---------------------------------------------------------------------------

    \5\ 77 FR 57914 (September 18, 2012).
---------------------------------------------------------------------------

    The EPA believes that this action is not likely to result in new 
disproportionate and adverse effects on people of color, low-income 
populations and/or Indigenous peoples. Because this final rule alters 
the existing requirements for regional haze in the State of Montana by 
including the enforceable shutdown of two sources and otherwise only 
transfers existing requirements from a FIP to the SIP, our 
determination is unchanged from that in 2012. The EPA additionally 
identified and addressed environmental justice concerns by performing a 
screening analysis using the EJScreen tool \6\ to evaluate 
environmental and demographic indicators for the areas impacted by this 
action. These results indicate that areas impacted by this final action 
are not potential areas of EJ concern and are not candidates for 
further EJ review. EPA is providing this information for public 
information purposes, and not as a basis of our final action. The 
information supporting this Executive Order review is contained in the 
docket for this action.
---------------------------------------------------------------------------

    \6\ EJSCREEN is an environmental justice mapping and screening 
tool that provides EPA with a nationally consistent dataset and 
approach for combining environmental and demographic indicators; 
available at https://www.epa.gov/ejscreen/what-ejscreen.
---------------------------------------------------------------------------

K. Determination Under Clean Air Act Section 307(d)

    The partial withdrawal of EPA's FIP in this action is subject to 
the provisions of CAA section 307(d) pursuant to section 307(d)(1)(B), 
which provides that section 307(d) applies to, among other things, 
``the promulgation or revision of an implementation plan by the 
Administrator under [CAA section 110(c)].'' \7\ The agency has complied 
with the procedural requirements of CAA section 307(d) during the 
course of this rulemaking with regard to the entirety of this action.
---------------------------------------------------------------------------

    \7\ 42 U.S.C. 7607(d)(1)(B).
---------------------------------------------------------------------------

L. Congressional Review Act

    This rule is exempt from the Congressional Review Act (CRA) because 
it is a rule of particular applicability that only applies to 4 
facilities.

M. 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 August 25, 2023. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of this action for 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 may not be challenged later in proceedings to enforce its 
requirements. See CAA section 307(b)(2).
