Background and Purpose</HD> 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. <HD SOURCE="HD2">a. NNSR Certification</HD> 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. <HD SOURCE="HD2">b. Emission Statement Certification</HD> 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 (NO <E T="52">X</E> ) or volatile organic compounds (VOCs) in an ozone nonattainment area. The owner of each stationary source that emits NO <E T="52">X</E> or VOCs must provide a statement each year of its NO <E T="52">X</E> 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. <HD SOURCE="HD1">II. Response to Comments</HD> 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. <HD SOURCE="HD1">III. Final Action</HD> EPA is approving Connecticut's SIP revisions pertaining to NNSR Certification and Emission Statement Certification. <HD SOURCE="HD1">IV. Statutory and Executive Order Reviews</HD> 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 <E T="03">et seq.</E> ); • 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 <E T="03">et seq.</E> ); • 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). The Congressional Review Act, 5 U.S.C. 801 <E T="03">et seq.,</E> 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 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Preview showing 10k of 14k characters.
