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

SUMMARY: The Environmental Protection Agency (EPA) is approving State 
Implementation Plan (SIP) revisions submitted by the State of 
Connecticut for the 2015 ozone National Ambient Air Quality Standard 
(NAAQS). These revisions certify the adequacy of the SIP to satisfy the 
nonattainment new source review permitting requirements of the Clean 
Air Act (CAA) for the reclassification of the Greater Connecticut area 
to moderate nonattainment for the 2015 ozone NAAQS, and certify the 
emission statement program satisfies CAA requirements for the initial 
nonattainment designations and the reclassification to moderate 
nonattainment for the 2015 ozone NAAQS. This action is being taken in 
accordance with the CAA.

I. Background and Purpose

    On September 27, 2024 (89 FR 79186), the EPA published a notice of 
proposed rulemaking (NPRM) for the State of Connecticut proposing to 
approve two SIP revisions submitted by the State. Information about the 
proposed SIP revisions are as follows.

a. NNSR Certification

    On May 22, 2023, the Connecticut Department of Energy and 
Environmental Protection (CT DEEP) submitted several revisions to its 
SIP. The first SIP revision certified the adequacy of the SIP to 
satisfy the nonattainment new source review (NNSR) permitting 
requirements of the CAA for the reclassification of the Greater 
Connecticut area to moderate nonattainment for the 2015 ozone National 
Ambient Air Quality Standards (NAAQS). Effective November 7, 2022, the 
EPA reclassified the Greater Connecticut nonattainment area to moderate 
nonattainment for the 2015 ozone NAAQS (see 87 FR 60897). Although CT 
DEEP had previously submitted, and EPA had approved, an NNSR 
certification for the 2015 ozone NAAQS initial classifications of 
marginal nonattainment for the Greater Connecticut nonattainment area 
(see 87 FR 38284, July 28, 2022), EPA's reclassification requires 
recertifying the adequacy of its NNSR program under the moderate 
nonattainment area requirements. The State certified that the versions 
of Regulations of Connecticut State Agencies (RCSA) sections 22a-174-1 
and 22a-174-3a in the current SIP meet the Federal NNSR requirements 
for the Greater Connecticut ozone nonattainment area. In Connecticut's 
certification, the State provided a side-by-side comparison 
demonstrating the State's Rules are at least as stringent as EPA's NNSR 
permitting program requirements.

b. Emission Statement Certification

    The second SIP revision certified that the emission statement 
program satisfies the requirements of CAA section 182(a)(3)(B) for the 
initial nonattainment designations and the reclassification to moderate 
nonattainment for the 2015 ozone NAAQS. CAA section 182(a)(3)(B) 
applies to stationary sources that emit nitrogen oxides 
(NOX) or volatile organic compounds (VOCs) in an ozone 
nonattainment area. The owner of each stationary source that emits 
NOX or VOCs must provide a statement each year of its 
NOX and VOC emissions, and the statement must be certified 
as to accuracy. Beginning with its initial emission statement program 
SIP filing on January 12, 1993 (approved on January 10, 1995; 60 FR 
2524), Connecticut administered its emission statement program under 
the recordkeeping and reporting requirements of section 22a-174-4 of 
the RCSA. On November 17, 2022, Connecticut submitted a new regulation, 
RCSA section 22a-174-4a, ``Source monitoring, record keeping and 
reporting,'' to EPA as a SIP revision to replace the rule it had 
previously used to implement an emissions statement program (section 
22a-174-4). This revision was approved into the SIP by final rule 
published July 8, 2024 (89 FR 55888), and associated correction notice 
published July 23, 2024 (89 FR 59620).
    The rationale for EPA's proposed actions for these revisions is 
explained in the NPRM and will not be restated here.

II. Response to Comments

    EPA received three comments during the comment period. The first 
comment generally supports the EPA's proposed action, although the 
commenter also discusses topics outside the scope of the action. The 
second comment focuses solely on irrelevant subjects. The third comment 
is disjointed and unclear. To the extent the commenter means to rely on 
any points made in the various references appearing in the comment, 
``EPA will generally not consider comments or comment contents located 
outside of the primary submission.'' 89 FR 79186. In any event, none of 
the comments assert, or explain how, EPA approval of this action would 
be erroneous or otherwise be inconsistent with the CAA, applicable 
regulations, or other authorities. As such, the comments do not require 
further response to finalize the action as proposed.

III. Final Action

    EPA is approving Connecticut's SIP revisions pertaining to NNSR 
Certification and Emission Statement Certification.

IV. 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, 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 Orders 12866 (58 
FR 51735, October 4, 1993);
     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 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).

[[Page 16816]]

    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. EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. 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 June 23, 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).)
