Why is the EPA using a direct final rule?</HD> The EPA is publishing this final rule approving the SDCAPCD's proposed title V program revisions without prior proposal because we consider it to be a noncontroversial action and anticipate no adverse comments. However, in the “Proposed Rules” section of this <E T="04">Federal Register</E> publication, the EPA is simultaneously publishing a proposal that will also serve as a public notice of San Diego's proposed title V program revisions pursuant to title 40 of the Code of Federal Regulations (CFR), section 70.4(i). <HD SOURCE="HD1">II. Background</HD> The CAA Amendments of 1990 include title V, which requires states to develop an operating permits program that meets the federal criteria codified in 40 CFR part 70. The title V program requires certain sources of air pollution to obtain federal operating permits from their respective states. These federal operating permits improve enforcement and compliance by consolidating all applicable federal requirements into one federally enforceable document. Before states can issue title V permits, the EPA must approve their programs as amendments to appendix A of part 70. States may submit revisions to their approved programs for EPA approval. See EPA's Technical Support Document (TSD) for a more detailed discussion of the history of the title V program approvals for SDCAPCD. <HD SOURCE="HD1">III. What is the State's proposed Title V program revision?</HD> Table 1 lists the rule submitted as part of the SDCAPCD's title V program revisions and the date it was adopted by the District and submitted by the California Air Resources Board (CARB), which is the governor's designee for California rule submittals. <GPOTABLE COLS="4" OPTS="L2,i1" CDEF="s50,r100,12,12"> <TTITLE>Table 1—Submitted Rules</TTITLE> <CHED H="1">Rule No.</CHED> <CHED H="1">Rule title</CHED> <CHED H="1">Amended date</CHED> <ENT>Title V Operating Permits—Permit Process—Public Notification</ENT> <ENT>10/12/2023</ENT> <ENT>01/19/2024</ENT> </ROW> <TNOTE> <SU>b</SU>  CARB transmitted the submittal to the EPA by letter dated January 19, 2024. </TNOTE> </GPOTABLE> The District submitted revisions to Rule 1415 (Title V Operating Permits—Permit Process—Public Notification) at Sections (a), (c), (d), (g), and (j) to conform to current public noticing, application publication, and record retention requirements codified at 40 CFR 70.5(c), 70.7(h) and 70.8(a)(3). Details regarding the revisions made, including a change-copy of Rule 1415, can be found in the TSD and the docket. <HD SOURCE="HD1">IV. EPA Evaluation of Title V Program Revision</HD> EPA finds the District revisions to Rule 1415 (Title V Operating Permits—Permit Process—Public Notification) at Sections (a), (c), (d), (g), and (j) conform to and are consistent with current public noticing, application publication, and record retention requirements codified at 40 CFR 70.5(c), 70.7(h) and 40 CFR 70.6(a)(3)(ii)(B), respectively. Details regarding the revisions made can be found in the TSD available at <E T="03">https://www.regulations.gov</E> . <HD SOURCE="HD1">V. Final Action</HD> As authorized in 40 CFR 70.4(i), the EPA is fully approving the submitted revisions because we find the proposed changes to Rule 1415 align with 40 CFR part 70 program elements. Therefore, the proposed changes are approvable as title V program revisions. We do not anticipate adverse comments, so we are finalizing this action without proposing it in advance. However, in the Proposed Rules section of this <E T="04">Federal Register</E> , we are simultaneously proposing approval of the same submitted rule. If we receive adverse comments on the proposed revisions by October 6, 2025, we will publish a timely withdrawal in the <E T="04">Federal Register</E> to notify the public that the direct final approval will not take effect. The EPA would then address all public comments in a subsequent final rule based on the proposed action. If we do not receive timely adverse comments, this direct final approval will be effective without further notice on November 4, 2025. Pursuant to section 307(b)(1) of the Act, judicial review of this final agency action may be sought by filing a petition for review in the United States Court of Appeals for the appropriate circuit within 60 days of publication in the <E T="04">Federal Register</E> . We do not plan to open a second comment period on this action, so any parties interested in commenting should do so at this time. <HD SOURCE="HD1">VI. Statutory and Executive Order Reviews</HD> <HD SOURCE="HD2">A. General Requirements</HD> Under the CAA, the Administrator is required to approve title V operating permit program revisions that comply with the Act and applicable federal regulations. See 42 U.S.C. 7661a(d). Thus, in reviewing title V permit program submissions, the EPA's role is to approve state choices, provided that they meet the criteria of the CAA. 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 it is not a significant regulatory action under Executive Order 12866; • 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 (Public Law 104-4); • Does not have federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); • Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); and • Is not subject to requi ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Preview showing 10k of 13k characters.
