I. Background and Purpose

    On June 23, 2022, Connecticut submitted SIP revisions required due 
to the State's classification as a Serious nonattainment area for the 
2008 ozone standard that included an RFP plan with motor vehicle 
emissions budgets (``budgets''), an enhanced vehicle emissions 
inspection and maintenance (I/M) program certification, and a 
certification that the State's previously adopted clean fuels program 
continues to meet CAA requirements. The State supplemented this 
submittal with additional information on November 17, 2022, and 
December 12, 2023. On November 21, 2024, (89 FR 92079), EPA published a 
Notice of Proposed Rulemaking (NPRM) for the State of Connecticut. The 
NPRM proposed approval of Connecticut's RFP plan for the 2018 to 2020 
timeframe, motor vehicle emissions budgets for 2020, certification of 
its enhanced I/M program, and clean fuels program certification, for 
the reasons articulated within our November 21, 2024 proposed rule. The 
specific requirements for these SIP elements and our rationale for 
proposing to approve them are explained in the NPRM and will not be 
restated here. No public comments were received on the NPRM.

II. Final Action

    EPA is approving plan submittals pertaining to requirements 
relating to reasonable further progress plans, an enhanced vehicle 
emissions inspection and maintenance program, transportation 
conformity, and a clean fuels for motor vehicles program, as revisions 
to the Connecticut SIP.

III. 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:
    <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);
    <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 subject to Executive Order 13045 (62 FR 19885, 
April 23, 1997) because it approves a State program;
    <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

[[Page 14342]]

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).
    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 2, 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).)

rate of progress requirement of section 182(b) through 2020 for the 
Connecticut portion of the New York-Northern New Jersey-Long Island, 
NY-NJ-CT area. The revisions also establish motor vehicle emissions 
budgets for 2020 of 17.6 tons per day of VOC and 23.3 tons per day of 
NO<INF>X</INF> to be used in transportation conformity in the 
Connecticut portion of the New York-Northern New Jersey-Long Island, 
NY-NJ-CT moderate ozone nonattainment area. Additionally, we are 
concurring with the State's determination that its I/M program meets 
the performance standard and requirements for Enhanced I/M, and 
determining that Connecticut meets the clean-fuel vehicle program of 
section 182(c)(4) of the Clean Air Act.
