🌍Proposed EPA Regulations Impacting California Air Quality Compliance
The Environmental Protection Agency (EPA) is proposing action on three permitting rules submitted as a revision to the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD or "District") portion of the California State Implementation Plan (SIP). These revisions concern the District's New Source Review (NSR) permitting program for new and modified sources of air pollution under section 110(a)(2)(C) and part D of title I of the Clean Air Act (CAA or "Act"). This action will update the California SIP with rules that the District has revised to address deficiencies identified in a previous limited disapproval action and to incorporate other revisions related to NSR requirements. We are taking comments on this proposal and plan to follow with a final action. Elsewhere in this Federal Register, we are making an interim final determination that will defer the imposition of CAA sanctions associated with our previous limited disapproval action. This action also proposes to revise regulatory text to clarify that the SJVUAPCD is not subject to the federal implementation plan related to protection of visibility.

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🌍Updated EPA Regulations on Aerosol Coatings and VOCs Compliance
The U.S. Environmental Protection Agency (EPA) is finalizing amendments to the National Volatile Organic Compound Emission Standards for Aerosol Coatings. This action revises national emission standards for the aerosol coatings (aerosol spray paints) category under the Clean Air Act (CAA), which requires control of volatile organic compound (VOC) emissions from certain categories of consumer and commercial products for purposes of reducing VOC emissions contributing to ozone formation and ozone nonattainment. The regulation employs a relative reactivity-based approach to control aerosol coating products' contribution to ozone formation by encouraging the use of less reactive VOC ingredients in formulations. In this final rule, the EPA is updating coating category product-weighted reactivity (PWR) limits, adding new compounds and reactivity factors, updating existing reactivity factors, revising the rule's default reactivity factor, amending thresholds for VOC regulated by the rule, amending reporting requirements, updating test methods to reflect more recent versions, adding a new compliance date, and making clarifying edits.

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🌍New SIP Deadlines and Compliance Requirements Under Ozone Regulations
The Environmental Protection Agency (EPA) is finalizing deadlines for submission of state implementation plan (SIP) revisions and implementation of the relevant control requirements that will apply for nonattainment areas reclassified as Moderate, Serious, and Severe under the current and any future ozone National Ambient Air Quality Standards (NAAQS) as a result of either failing to attain the standard by the applicable classification attainment date or the EPA granting a voluntary reclassification request. This final rule articulates the implementation requirements and timeframes that will apply for all such areas once reclassified. The EPA is also finalizing regulatory revisions to codify its existing interpretation that following reclassification, a state is no longer required to submit SIP revisions addressing certain, but not all, requirements related to the prior classification level for an ozone nonattainment area.
Learn More🌍New EPA Updates to Alaska Air Quality Regulations Announced
The Environmental Protection Agency (EPA) is updating the materials that are incorporated by reference (IBR) into the Alaska State Implementation Plan (SIP). The regulations affected by this update have been previously submitted by the State of Alaska and approved by the EPA. In this final rule, the EPA is also notifying the public of corrections and clarifying changes in the Code of Federal Regulations tables that identify the materials incorporated by reference into the Alaska SIP. This update affects the materials that are available for public inspection at the National Archives and Records Administration and the EPA Regional Office.
Learn More🌎EPA Approves Air Quality Revisions in Maricopa County, Arizona
The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Maricopa County Air Quality Department (MCAQD or "County") portions of the Arizona State Implementation Plan (SIP). These revisions concern the County's reasonably available control technology (RACT) demonstration for the aerospace coating category and negative declarations for the 2008 8- hour ozone National Ambient Air Quality Standards (NAAQS or "standards") in the portion of the Phoenix-Mesa ozone nonattainment area regulated by the MCAQD, as well as a rule covering emissions of volatile organic compounds (VOCs) from surface coatings and industrial adhesives. We are also approving a local rule that regulates these emission sources under the Clean Air Act (CAA or "the Act").
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.
Learn More🌍Kansas EPA Proposes New Emission Fees and Compliance Rules
The Environmental Protection Agency (EPA) is proposing to approve revisions to the State Implementation Plan (SIP) and Operating Permits Program and the 112(l)plan submitted by the State of Kansas on February 20, 2023. The revised Kansas rules update the Class I emission fee and emissions inventory regulations, establish a Class II fee schedule and ensure that Kansas's Operating Permits Program is adequately funded. Approval of these revisions ensures consistency between the State and federally-approved rules and does not impact air quality.
