The Environmental Protection Agency (EPA) is making an interim final determination that the California Air Resources Board (CARB) has submitted a Clean Air Act (CAA or "Act") state implementation plan (SIP) revision on behalf of the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD or "District") that corrects deficiencies concerning the District's new source review (NSR) stationary source permitting program. This determination is based on a proposed approval, published elsewhere in this issue of the Federal Register, of SJVUAPCD Rules 1020, 2020, and 2201. The effect of this interim final determination is to defer sanctions that were triggered by the EPA's limited disapproval of SJVUAPCD Rule 2201 in 2023.

Learn More🔥EPA Approves Removal of Recreational Fires Ban in Washington
The Environmental Protection Agency (EPA) is approving a revision to the Washington State Implementation Plan (SIP) that was submitted by the Department of Ecology (Ecology) in coordination with the Olympic Region Clean Air Agency (ORCAA). In 2013, Ecology and ORCAA inadvertently submitted for incorporation into the SIP a ban on small, recreational fires in Thurston County. These fires are defined as having a maximum pile size of three feet in diameter by two feet high using seasoned firewood or charcoal, generally associated with backyard, summer campfires. Ecology and ORCAA provided a review of the historical record to demonstrate that the ban on recreational fires was not relied upon for attainment, maintenance, or reasonable further progress in the Thurston County area. Ecology and ORCAA also provided data to demonstrate that removing the ban on recreational fires would not interfere with maintenance of the national ambient air quality standards. Therefore, we are approving the request by Ecology and ORCAA to remove this provision from the SIP.

The Environmental Protection Agency (EPA) is revising a Federal Implementation Plan (FIP) applicable to sulfur dioxide (SO<INF>2</INF>) emissions from four sources located in Billings and Laurel, Montana. Specifically, the EPA is revising a portion of the FIP promulgated by the EPA in 2008 (2008 Billings/Laurel SO<INF>2</INF> FIP) by removing a provision which contained an affirmative defense for exceedances of flare emission limits during malfunctions, startups, and shutdowns. The EPA is taking this action pursuant to the Clean Air Act (CAA).
Learn More🌍Montana EPA Approves Change to Oxygenated Fuels Program
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the Montana Department of Environmental Quality (MDEQ or "the State"), on January 30, 2024, requesting to change the status of gasoline requirements (the "oxygenated fuels" or "oxyfuels" program) in the Missoula, Montana Carbon Monoxide (CO) Limited Maintenance Plan (LMP) from active control measure to a contingency measure. 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.
