The SIP revision contains a non-interference demonstration under the Clean Air Act (CAA), which concludes that converting the oxygenated gasoline program from a control measure to a contingency measure in the Missoula CO LMP would not interfere with attainment or maintenance of the CO National Ambient Air Quality Standard (NAAQS). The EPA is finalizing approval of Montana's SIP submittal pursuant the CAA. </SUM> <EFFDATE> <HD SOURCE="HED">DATES:</HD> This rule is effective on February 18, 2025. </EFFDATE> <HD SOURCE="HED">ADDRESSES:</HD> The EPA has established a docket for this action under Docket ID No. EPA-R08-OAR-2023-0473.

Background</HD> The background for this action is discussed in detail in our October 15, 2024, proposal (89 FR 82953). In that document we proposed to approve a SIP revision submitted by Montana on January 30, 2024. The submission included a request to change the status of the oxyfuels program in Missoula CO LMP from an active control measure to a contingency measure, as well as several ministerial and conforming changes to the related State regulations. To support the request, Montana's January 30, 2024 SIP revision contains technical support materials to demonstrate the removal of the rules as control measures will not interfere with attainment or maintenance of the CO NAAQS or with any other applicable requirement of the CAA. Specifically, the SIP revision addresses State regulations amended in the Missoula City-County Air Pollution Control (MCCAPC) program rules, Chapter 10: <E T="03">Fuels,</E> Subchapter 1: <E T="03">Oxygenated Fuels Program,</E> rules. 10.102(1), 10.105(1), 10.109(1), 10.110, 10.111, 10.111(2). In our proposed rulemaking, the EPA's analysis of Montana's January 30, 2024 SIP revision was organized into two parts under section II of this preamble. Part A provided the background, analysis, and discussion of non-interference demonstration for the change in status of Montana's oxyfuels program from a control measure to a contingency measure in the federally approved Montana SIP; Part B contained information regarding the rules submitted for revision in the MCCAPC Chapter 10: <E T="03">Fuels,</E> Subchapter 1: <E T="03">Oxygenated Fuels Program.</E> The EPA is finalizing to act on the revision listed in the action. We received one comment on the proposed rulemaking. Our response to the comment is found below. <HD SOURCE="HD1">II. Response to Comments</HD> <E T="03">Comment:</E> The commenter stated that they are in favor of the proposed rulemaking and believe it will help reduce pollution by reducing reliance on carbon-based fuels. The commenter also expressed that this rule would move society toward a greener future and reduce the influence of oil companies. <E T="03">Response:</E> We appreciate the commenter's support for the proposed rulemaking. However, the comment is outside the scope of this action, as this rulemaking is limited to approving a SIP revision reclassifying the oxygenated gasoline program in the Missoula CO LMP from a control measure to a contingency measure. <HD SOURCE="HD1">III. Final Action</HD> For the reasons explained in our proposal, the EPA is finalizing its approval of Montana's January 30, 2024 SIP revision seeking to revise various air quality rules and to remove the oxygenated gasoline program from Montana's SIP as a control measure and make it a contingency measure instead. The EPA has the authority to approve removal of a State's oxygenated gasoline program as specified in CAA section 211(m)(6) and has determined that the criteria of CAA section 211(m)(6) has been satisfied. The EPA has determined that Montana has demonstrated that removal of the oxygenated fuels program from the SIP will not interfere with continued attainment or maintenance of any applicable NAAQS or with any other applicable requirement of the CAA, and that the requirements of CAA section 110(l) have been satisfied. As a result, the EPA is finalizing its approval of the changes to the MCCAPC oxyfuels program rules, Chapter 10: <E T="03">Fuels,</E> Subchapter 1: <E T="03">Oxygenated Fuels Program,</E> rules 10.102(1), 10.105(1), 10.109(1), 10.110, 10.111, 10.111(2) as submitted by Montana on January 30, 2024. <HD SOURCE="HD1">IV. Incorporation by Reference</HD> In this document, the EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is finalizing the incorporation by reference of the revised MCCAPC oxyfuels program rules, Chapter 10: <E T="03">Fuels,</E> Subchapter 1: <E T="03">Oxygenated Fuels Program,</E> rules 10.102(1), 10.105(1), 10.109(1), 10.110, 10.111, 10.111(12). These rules revise various air quality regulations by correcting spelling and other clerical errors and remove the oxygenated gasoline program from Montana's SIP. The EPA is finalizing the incorporation by reference of the regulations described in the amendments to 40 CFR part 52 set forth below. The EPA has made, and will continue to make, these materials generally available through <E T="03">www.regulations.gov</E> and at the EPA Region 8 Office (please contact the person identified in the <E T="02">FOR FURTHER INFORMATION CONTACT</E> section of this preamble for more information). Therefore, these materials have been approved by the EPA for inclusion in the SIP, have been incorporated by reference by the EPA into that plan, are fully federally enforceable under sections 110 and 113 of the CAA as of the effective date of the final rulemaking of the EPA's approval, and will be incorporated by reference in the next update to the SIP compilation. <SU>1</SU> <FTREF/> <FTNT> <SU>1</SU>  62 FR 27968 (May 22, 1997). </FTNT> <HD SOURCE="HD1">V. 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 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 Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); • 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, 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 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); • 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 CAA; and 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 b ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Preview showing 10k of 16k characters.
