Statutory and Executive Order Reviews</FP> </EXTRACT> <HD SOURCE="HD1">I. Background</HD> On June 26, 2024, the Oregon Department of Environmental Quality (DEQ) and the Lane Regional Air Protection Agency (LRAPA) submitted revisions to the Oregon SIP, codified at 40 CFR part 52, subpart MM. The Oregon DEQ is the permitting authority throughout the State, except where LRAPA has been authorized to permit sources located in Lane County, Oregon. The submitted changes, State effective May 25, 2024, update the stationary source permitting programs established in LRAPA regulations to align with recent changes to State rules (89 FR 59611, July 23, 2024). On September 5, 2025, the EPA proposed to approve the submitted revisions (90 FR 42867). <SU>1</SU> <FTREF/> The reasons for our proposed approval were stated in the proposed rulemaking and will not be re-stated here. The public comment period for our proposed action ended on October 6, 2025. We received no comments. <FTNT> <SU>1</SU>  We did not propose action on the submitted changes to title 36 of the LRAPA regulations. We intend to address them in a separate, future action. </FTNT> <HD SOURCE="HD1">II. Final Action</HD> The EPA approves revisions to the Oregon SIP applicable in Lane County and submitted on June 26, 2024. <SU>2</SU> <FTREF/> These changes are approved only to the extent the requirements apply to: (1) pollutants for which NAAQS have been established (criteria pollutants) and precursors to those criteria pollutants as determined by the EPA for the applicable geographic area; and (2) any additional pollutants that are required to be regulated under part C of title I of the Clean Air Act, but only for the purposes of meeting or avoiding the requirements of part C of title I of the Clean Air Act. The following paragraphs detail our incorporations by reference. <FTNT> <SU>2</SU>  We intend to address the submitted changes to title 36 of the LRAPA regulations in a separate, future action. </FTNT> <HD SOURCE="HD2">A.
