I. What is being addressed in this document?

    The EPA is approving West Virginia's regional haze SIP revision for 
the second implementation period, also referred to as the second 
planning period. As required by section 169A of the CAA, the RHR calls 
for State and Federal agencies to work together to improve visibility 
in 156 national parks and wilderness areas, known as mandatory Class I 
Federal areas.\1\ The rule requires the States, in coordination with 
the EPA, the National Park Service, the Fish and Wildlife Service, the 
Forest Service, and other interested parties, to develop and implement 
air quality protection plans to reduce the pollution that causes 
visibility impairment in mandatory Class I Federal areas. Visibility 
impairing pollutants include fine and coarse particulate matter (PM) 
(e.g., sulfates, nitrates, organic carbon, elemental carbon, and soil 
dust) and their precursors (e.g., sulfur dioxide (SO2), 
oxides of nitrogen (NOX), and, in some cases, volatile 
organic compounds (VOC) and ammonia (NH3)). As discussed in 
our proposed rulemaking, in section III of this preamble, and in the 
accompanying Response to Comments (RTC) document, the EPA finds that 
West Virginia's regional haze SIP meets the statutory and regulatory 
requirements for the regional haze second planning period.

II. Summary of the Proposed Action and the EPA's Reasons for This Final 
Action

A. Summary of the Proposed Action

    On August 12, 2022, the West Virginia Department of Environmental 
Protection (WV DEP) submitted a revision to the West Virginia SIP to 
address regional

[[Page 29738]]

haze for the second planning period. WV DEP submitted this SIP revision 
to satisfy the requirements of the CAA's regional haze program pursuant 
to CAA sections 169A and 169B and 40 Code of Federal Regulations (CFR) 
51.308.
    The EPA published a notice of proposed rulemaking (NPRM) proposing 
disapproval of West Virginia's August 12, 2022 SIP revision on January 
21, 2025 (90 FR 6932). The public comment period closed on February 20, 
2025. During that public notice-and-comment period, the EPA received 
six sets of comments. The full text of comments received on that NPRM 
are available via Docket ID Number EPA-R03-OAR-2024-0625 at 
www.regulations.gov.
    The EPA subsequently published a new NPRM on April 18, 2025 (90 FR 
16478), that withdrew the NPRM published on January 21, 2025 (90 FR 
6932), commenced a public notice-and-comment period via Docket ID 
Number EPA-R03-OAR-2025-0174, and proposed to fully approve all 
elements of West Virginia's August 12, 2022 SIP revision as meeting the 
requirements of the CAA and RHR. In the April 18, 2025 NPRM, the EPA 
also announced a new policy that, where visibility conditions for a 
Class I Federal area impacted by a State are below the Unform Rate of 
Progress (URP) and the State has considered the four statutory factors, 
the State will have presumptively demonstrated reasonable progress for 
the second planning period for that area. The NPRM provided background 
on the requirements of the CAA and RHR, summarized West Virginia's 
regional haze SIP submittal, and explained the EPA's rationale for its 
proposed action. That background and rationale will not be restated in 
full here.

B. Reasons for This Final Action

    In this final action, the EPA is affirming that it is now the 
Agency's policy that, where visibility conditions for a Class I Federal 
area impacted by a State are below the URP and the State has considered 
the four statutory factors, the State will have presumptively 
demonstrated reasonable progress for the second planning period for 
that area. The EPA acknowledges that this final action reflects a 
change in policy as to how the URP should be used in the evaluation of 
regional haze second planning period SIPs but believes that this policy 
better aligns with the purpose of the statute and RHR: achieving 
``reasonable'' progress towards natural visibility.
    As described in the April 18, 2025 (90 FR 16478) NPRM, the EPA has 
discretion and authority to change policy. In FCC v. Fox Television 
Stations, Inc., the U.S. Supreme Court plainly stated that an agency is 
free to change a prior policy and ``need not demonstrate . . . that the 
reasons for the new policy are better than the reasons for the old one; 
it suffices that the new policy is permissible under the statute, that 
there are good reasons for it, and that the agency believes it to be 
better.'' 566 U.S. 502, 515 (2009) (referencing Motor Vehicle Mfrs. 
Ass'n of United States, Inc. v. State Farm Mut. Auto. Ins. Co., 463 
U.S. 29 (1983)). See also Perez v. Mortgage Bankers Assn., 135 S. Ct. 
1199 (2015).
    The Class I areas impacted by emissions from WV are all below the 
URP, and WV's SIP submittal demonstrated that the state took into 
consideration the four reasonable progress factors listed in CAA 
169A(g)(1) \2\ with respect to an adequate number of emissions sources. 
Thus, the EPA has determined that WV's SIP revision is fully approvable 
under the Agency's new policy. Indeed, we think this policy better 
aligns with the statutory goal because it recognizes the considerable 
improvements in visibility impairment that have been made by a wide 
variety of State and Federal programs in recent decades.\3\
---------------------------------------------------------------------------

    \2\ The four statutory factors required to be taken into 
consideration in determining reasonable progress are: the costs of 
compliance, the time necessary for compliance, and the energy and 
nonair quality environmental impacts of compliance, and the 
remaining useful life of any existing source subject to such 
requirements. CAA section 169(g)(1).
    \3\ In addition, as we noted in the NPRM, certain commenters 
advocated for this policy during the public comment period for the 
NPRM that was published on April 18, 2025 (90 FR 16478), including 
Monongahela Power Company (Mon Power), the owner of two of the power 
plants selected for evaluation in the SIP submittal. See Mon Power's 
February 20, 2025 comment letter.
---------------------------------------------------------------------------

    Understanding what the URP is and how it has been used in the 
context of the RHR is important to understanding the implications of 
the policy change the EPA is finalizing in this action. In developing 
the regulations required by CAA section 169A(b), the EPA established 
the concept of URP for each Class I area. The URP is determined by 
drawing a straight line from the measured 2000-2004 baseline conditions 
(in deciviews) for the 20% most impaired days at each Class I area to 
the estimated 20% most impaired days natural conditions (in deciviews) 
in 2064. From this calculation, a URP value can be calculated for each 
year between 2004 and 2064. For each Class I area, there is a 
regulatory requirement to compare the projected visibility impairment 
(represented by the reasonable progress goal, or ``RPG'') at the end of 
each planning period to the URP (e.g., in 2028 for the second planning 
period).\4\ 40 CFR 308(f)(1)(vi). If the projected RPG is above the 
URP, then an additional ``robust demonstration'' requirement is 
triggered for each state that contributes to that Class I Federal area. 
40 CFR 308(f)(3)(ii).
---------------------------------------------------------------------------

    \4\ We note that RPGs are a regulatory construct that we 
developed to address statutory mandate in section 169B(e)(1), which 
required our regulations to include ``criteria for measuring 
`reasonable progress' toward the national goal.'' Under 40 CFR 
51.308(f)(3)(ii), RPGs measure the progress that is projected to be 
achieved by the control measures a state has determined are 
necessary to make reasonable progress. Consistent with the 1999 RHR, 
the RPGs are unenforceable, though they create a benchmark that 
allows for analytical comparisons to the URP and mid-implementation-
period course corrections if necessary. 82 FR at 3091-3092, January 
10, 2017.
---------------------------------------------------------------------------

    In comments on the EPA's January 21, 2025 (90 FR 6932) NPRM, West 
Virginia explained the following: ``The DAQ [WV DEP's Division of Air 
Quality] asserts progress towards decreasing visibility impairment 
since the first implementation period has immensely exceeded the 
expectations of the EPA, States, Federal land managers, and the public, 
causing an unreasonable belief additional visibility improvement can 
continue indefinitely at such a rapid pace via arbitrary federally 
enforceable emissions limits.'' \5\ The State also disagreed ``with the 
assertion that its four-factor analysis was insufficient because it did 
not reach the conclusion additional controls were required.'' \6\ 
Similarly, Mon Power commented that Class I Federal areas ``are 
presently well below the URP glide paths, proving that already 
implemented past measures have been and continue to be successful.'' 
\7\

    \6\ See p. 5 of WV DEP's February 19, 2025 comment letter.

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

    In the 2017 RHR Revisions, the EPA addressed the role of the URP as 
it relates to a State's development of its second planning period SIP. 
82 FR 3078 (January 10, 2017). Specifically, in response to comments 
suggesting that the URP should be considered a ``safe harbor'' and 
relieve States of any obligation to consider the four statutory 
factors, the EPA explained that the URP was not intended to be such a 
safe harbor. 82 FR at 3099, January 10, 2017. The EPA summarized such 
comments as follows:

    ``Some commenters stated a desire for corresponding rule text 
dealing with situations where RPGs are equal to (``on'') or better 
than (``below'') the URP or glidepath. Several commenters stated 
that the URP or glidepath should be a ``safe harbor,'' opining

[[Page 29739]]

that states should be permitted to analyze whether projected 
visibility conditions for the end of the implementation period will 
be on or below the glidepath based on on-the-books or on-the-way 
control measures, and that in such cases a four-factor analysis 
should not be required.'' Id.

    Other comments indicated a similar approach, such as ``a somewhat 
narrower entrance to a `safe harbor,' by suggesting that if current 
visibility conditions are already below the end-of-planning-period 
point on the URP line, a four-factor analysis should not be required.'' 
Id. The EPA was clear in its response: ``We do not agree with either of 
these recommendations.'' The EPA explained its position as follows: 
``The CAA requires that each SIP revision contain long-term strategies 
for making reasonable progress, and that in determining reasonable 
progress states must consider the four statutory factors. Treating the 
URP as a safe harbor would be inconsistent with the statutory 
requirement that states assess the potential to make further reasonable 
progress towards natural visibility goal in every implementation 
period.'' Id. (footnote omitted).
    Importantly, the EPA's new policy does not make the URP a safe 
harbor. The new policy merely creates a presumption that the State's 
second planning period SIP is making reasonable progress for a Class I 
Federal Area if the State has taken into consideration the four 
statutory factors of 169A(g)(1) and that area is below the URP. This is 
consistent with the CAA and RHR.

III. Public Comments Received on the Proposed Action and Responses to 
Comments

    During the public notice-and-comment period, the EPA received 22 
sets of comments on its April 18, 2025 proposal. Seventeen sets of 
comments supported the EPA's proposed action; these included comments 
from various state entities, specific utility companies, and coalitions 
and councils representing utilities. The EPA acknowledges these 
supportive comments, which are included in the docket for this action.
    Five sets of comments were opposed to the EPA's proposed action; 
these included comments from two individuals, one of the regional 
planning organizations for visibility, and two coalitions of 
conservation groups or environmental organizations.
    While we address a number of these adverse comments directly in 
this FRN, our full responses are included in the Response to Comment 
(RTC) document in the docket for this action. We briefly address in 
this section: (1) whether the EPA's new policy is consistent with the 
CAA and RHR; (2) whether the EPA sufficiently justified its basis for 
the new policy; (3) whether the action is nationally applicable or 
based on a determination of nationwide scope and effect; (4) whether 
the action departs from national policy without complying with the 
EPA's consistency regulations at 40 CFR part 56; and (5) whether the WV 
SIP met the requirements of the new policy.
    As detailed at length in the RTC document in the response at 
III.A.3, the EPA's new policy is consistent with the CAA. Pursuant to 
CAA 169A(a)(4), Congress explicitly delegated to the EPA the authority 
to promulgate regulations regarding reasonable progress towards meeting 
the national goal. As some comments suggest, to determine the measures 
necessary to make reasonable progress towards the national visibility 
goal under 169A(a)(1), Congress mandated ``tak[ing] into consideration 
the cost of compliance, the time necessary for compliance, and the 
energy and nonair quality environmental impacts of compliance, and the 
remaining useful life of any existing source subject to such 
requirement.'' CAA 169A(g)(1).
    However, nothing in the statute defines what it means ``to take 
into consideration'' the four factors under CAA 169A(g)(1). Under this 
statutory framework, the EPA has been empowered by Congress to give 
meaning to this statutory phrase. Loper Bright Enters. v. Raimondo, 603 
U.S. 369, 395 (2024). The phrase ``to take into consideration'' implies 
a broader process not limited to the four statutory factors, allowing 
states to weigh in other factors, like visibility, to support their 
determination of whether additional measures are necessary to make 
reasonable progress at Class I Federal areas. This follows from 
reasonable progress requiring the improvement of visibility. CAA 
169A(b)(2). As such, visibility improvement must be a fundamental part 
of determining the extent of progress that is considered reasonable.
    Being below the URP does not relieve a State of its obligations 
under the CAA and the RHR to make reasonable progress. Also, being 
below the URP is not a safe harbor because the EPA still reviews a 
State's determination of whether additional control measures are 
necessary for reasonable progress, whether the state submitted those 
measures for incorporation into the SIP, and whether the measures are 
consistent with other provisions in the CAA.
    As required by the statute, West Virginia took into consideration 
the four statutory factors in CAA section 169A(g)(1) and determined 
that the sources selected were in compliance with already implemented 
emission control measures which continue to be successful, and that no 
additional SO2 controls were necessary to make reasonable 
progress. Further, CAA section 169A(b)(2) requires SIPs to include 
``such emission limits, schedules of compliance and other measures as 
may be necessary to make reasonable progress.'' Congress explicitly 
stated its intent for states to only include mechanisms as may be 
necessary for a Class I Federal area to achieve reasonable progress. 
West Virginia concluded that it was not necessary to incorporate any 
new emission limitations, schedules of compliance, or other measures 
into its SIP. Thus, West Virginia did not ignore the results of its 
consideration of the four statutory factors. Rather, consistent with 
the EPA's new policy, the state properly used the URP to inform its 
final decision making as to the measures necessary to make reasonable 
progress in the second planning period.
    As discussed in the RTC document at III.C.3, the EPA's change in 
policy is consistent with FCC v. Fox Television, 556 U.S 502 (2009). 
Under FCC v. Fox, an agency's change in policy is permissible if the 
agency acknowledges the change, believes it to be better, and ``show[s] 
that there are good reasons for the new policy.'' 556 U.S. 502, 515. In 
our proposal for this rulemaking, we stated our reasons for 
implementing this new policy. 90 FR 16478, April 18, 2025. In section 
I, What action is the EPA proposing?, of the rulemaking, we stated: 
``Based on our change in policy discussed in section V of this 
preamble, the EPA proposes that West Virginia's regional haze SIP meets 
the statutory and regulatory requirements for the regional haze second 
planning period.'' The EPA more fully articulated the substance of the 
change in policy in section V, The EPA's Rationale for Proposing 
Approval, of that rulemaking. Id. at 16482-84. In sum, the EPA's 
proposal sufficiently justifies the change in policy under FCC v. Fox.
    The decision in FCC v. Fox turned primarily on whether the FCC's 
change in policy would lead to the FCC ``arbitrarily punishing parties 
without notice of the potential consequences of their action.'' 556 
U.S. at 517. As we explained in the proposal, the changed policy is 
prospective, which addresses the primary concern in FCC v. Fox. 
Additionally, the new policy ``aligns with the purpose of the statute 
and RHR, which is achieving `reasonable' progress, not maximal 
progress, toward

[[Page 29740]]

Congress' natural visibility goal.'' Id. at 16483. Furthermore, we note 
that the legislative history of CAA section 169A is consistent with our 
change in policy. The reconciliation report for the 1977 CAA amendments 
indicates that the term ``maximum feasible progress'' in section 169A 
was changed to ``reasonable progress'' in the final version of the 
legislation passed by both chambers. See Legislative History of the 
Clean Air Act Amendments of 1977 Public Law 95-95 (1977), H.R. Rep. No. 
95-564, at 535.
    As we explain in the RTC document in the response at III.B.2, the 
EPA's Regional Consistency regulations at 40 CFR part 56, and in 
particular 40 CFR 56.5(b), are not relevant to this action. 40 CFR 
56.5(b) requires that a ``responsible official in a Regional office 
shall seek concurrence from the appropriate EPA Headquarters office on 
any interpretation of the Act, or rule, regulation, or program 
directive when such interpretation may result in application of the act 
or rule, regulation, or program directive that is inconsistent with 
Agency policy.'' (emphasis added). As we expressly indicated in the 
proposed WV SIP approval, the approval is consistent with the announced 
change in agency policy. Therefore, there is no obligation under the 
plain language of the EPA's Regional Consistency regulations for anyone 
in the region to seek concurrence from EPA Headquarters to take action 
consistent with EPA policy. The lack of relevance of these regulations 
to this action accounts for the lack of materials related to compliance 
with the Regional Consistency process in the docket for this 
rulemaking.
    As discussed in the RTC document in the response at III.D.2, this 
action is ``locally or regionally applicable'' under CAA section 
307(b)(1) because it applies only to a SIP submission from a single 
state, West Virginia. See Oklahoma v. EPA, 605 U.S. __, __-__ (2025) 
(slip op., at 8) (a SIP is ``a state-specific plan'' and ``the CAA 
recognizes this limited scope in enumerating a SIP approval as a 
locally or regionally applicable action''); see also, Am. Rd. & Transp. 
Builders Ass'n, 705 F.3d 453, 455 (D.C. Cir. 2013) (describing EPA 
action to approve a single SIP under CAA section 110 as the 
``[p]rototypical'' locally or regionally applicable action). Whether 
our proposal to approve West Virginia's second planning period SIP `` 
`announc[es]' a `new' national policy'' has no bearing on the 
applicability of EPA's final action. To determine whether an action is 
``nationally applicable'' or ``locally or regionally applicable,'' 
``court[s] need look only to the face of the agency action, not its 
practical effects. . . .'' EPA v. Calumet Shreveport Refining, L.L.C., 
605 U.S. __ (2025) (slip op. at 12) (``[W]e determine an action's range 
of applicability by `look[ing] only to the face of the [action], rather 
than to its practical effects.' '') (quoting Am. Rd. & Transp. Builders 
Ass'n., 705 F. 3d at 456) and Oklahoma, 605 U.S. __, __-__ (2025) (slip 
op. at 9) (basis for EPA action is not relevant to determining its 
applicability); see also Sierra Club v. EPA, 926 F.3d 844, 849 (D.C. 
Cir. 2019) and RMS of Georgia, LLC v. EPA, 64 F.4th 1368, 1372 (11th 
Cir. 2023) (``our sister circuits have established a consensus that we 
should begin our analysis by analyzing the nature of the EPA's action, 
not the specifics of the petitioner's grievance''). Furthermore, the 
comments that claim that this action ``amend[s] the nationally 
applicable RHR'' are unsupported and incorrect. This action simply 
applies a new policy related to the URP in the context of the EPA's 
evaluation of West Virginia's regional haze SIP submission. Because 
this action applies a new policy to a SIP submission from West Virginia 
alone, it is locally or regionally, not nationally, applicable.
    Second, comments that claim that the EPA ``must'' publish a finding 
that this action is ``based on a determination of nationwide scope [or] 
effect'' are also unsupported and incorrect. The Supreme Court has 
recognized that ``[b]ecause the `nationwide scope or effect' exception 
can apply only when `EPA so finds and publishes' that it does, EPA can 
decide whether the exception is even potentially relevant.'' Calumet 
Shreveport Refining, L.L.C., 605 U.S. __ (slip op. at 16), citing 
Sierra Club v. EPA, 47 F.4th 738, 746 (D.C. Cir. 2022). As the D.C. 
Circuit has also stated, the ``EPA's decision whether to make and 
publish a finding of nationwide scope or effect is committed to the 
agency's discretion and thus is unreviewable.'' Sierra Club v. EPA, 47 
F.4th at 745; see also Texas v. EPA, 983 F.3d 826, 835 (5th Cir. 2020) 
(``when a locally applicable action is based on a determination of 
nationwide scope or effect, the EPA has discretion to select the venue 
for judicial review'').
    The Administrator has not made and published a finding that this 
action is based on a determination of nationwide scope or effect. 
Accordingly, any petition for review of this action must be filed in 
the United States Court of Appeals for the appropriate regional 
circuit.
    Finally, as detailed in the RTC document in the responses at 
section IV, West Virginia met the requirements of the new policy. 
First, the RHR requires states to submit a long-term strategy that 
addresses regional haze visibility impairment for each mandatory Class 
I Federal area within the State and for each mandatory Class I Federal 
area located outside the State that may be affected by emissions from 
the State, 40 CFR 51.308(f)(2), and the statute refers to ``for a State 
the emissions from which may reasonably be anticipated to cause or 
contribute to any impairment of visibility in any such area'' CAA 
section 169A(b)(2). However, there is no specific statutory or 
regulatory requirement to identify the precise set of Class I areas 
that are affected by emissions from the State of West Virginia, and 
there is no requirement to establish a source contribution threshold in 
identifying those areas. In this case, WV DEP identified affected out-
of-state Class I areas in several ways, as we explain in the RTC 
document at response section IV.A.5, none of which are above the 2028 
URP.
    The EPA believes WV DEP has reasonably documented the out-of-state 
Class I area contributions, and they are not reasonably anticipated to 
cause or contribute to any impairment in any area that is above the 
URP.
    In conclusion, as discussed in more detail in the responses at 
section IV of the RTC document, West Virginia took into consideration 
the four statutory factors in CAA section 169A(g)(1) and determined 
that the specific sources selected for four-factor analyses were in 
compliance with already implemented emission control measures which 
continue to be successful, and that no additional SO2 
controls were necessary to make reasonable progress. Further, section 
169A(b)(2) of the Act requires SIPs to include ``such emission limits, 
schedules of compliance and other measures as may be necessary to make 
reasonable progress.'' Congress explicitly stated its intent for states 
to only include mechanisms as may be necessary for Class I Federal 
areas to achieve reasonable progress. West Virginia concluded that it 
was not necessary to incorporate any new emission limitations, 
schedules of compliance, or other measures into its SIP for these 
sources. Thus, West Virginia did not ignore the results of its 
consideration of the four statutory factors; rather, as supported by 
the new policy, the State properly used the URP to inform its final 
decision making as to the measures necessary to make reasonable 
progress in the second planning period.
    The full text of comments received is included in the publicly

www.regulations.gov. The RTC document, which is also included in the 
docket associated with this action, provides detailed responses to all 
significant comments received. The RTC document is organized by topic. 
Therefore, if additional information is desired concerning how the EPA 
addressed a particular comment, the reader should refer to the 
appropriate section in the RTC document.

IV. Final Action

    For the reasons set forth in the April 18, 2025 NPRM, the RTC 
document, and in this final rule, the EPA is approving West Virginia's 
August 12, 2022 SIP submittal as satisfying the regional haze 
requirements for the second planning period contained in 40 CFR 
51.308(f).

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 Clean Air Act 
and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, the EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
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:
     Is not a significant regulatory action subject to review 
by the Office of Management and Budget under Executive Order 12866 (58 
FR 51735, October 4, 1993);
     Is not subject to Executive Order 14192 (90 FR 9065, 
February 6, 2025) because SIP actions are exempt from review 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 subject to Executive Order 13045 (62 FR 19885, 
April 23, 1997) because it approves a state program;
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001); and
     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 the 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).
    This action is subject to the Congressional Review Act, and the EPA 
will submit a rule report to each House of the Congress and to the 
Comptroller General of the United States. This action is not a ``major 
rule'' as defined by 5 U.S.C. 804(2).
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by September 5, 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 may not be challenged later in 
proceedings to enforce its requirements. (See section 307(b)(2).)
