🌫️Approval of Updates to South Carolina's Cross-State Air Pollution Rule
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted through the South Carolina Department of Health and Environmental Control (SC DHEC) on September 26, 2023, regarding updates to the State's Cross-State Air Pollution Rule (CSAPR) emissions trading programs. The SIP revision incorporates by reference (IBRs) certain amendments EPA has made to the regulations for the Federal CSAPR trading programs for annual emissions of nitrogen oxides (NO<INF>X</INF>) and sulfur dioxide (SO<INF>2</INF>) for large electric generating units (EGUs). EPA is approving South Carolina's September 26, 2023, SIP revision because it is consistent with EPA's good neighbor CSAPR trading programs and the Clean Air Act (CAA or Act).

The Environmental Protection Agency (EPA) is taking final action to correct a November 19, 2020, rulemaking removing the Air Nuisance Rule (ANR) from the Ohio State Implementation Plan (SIP). This action is in response to a February 10, 2023, decision by the United States Court of Appeals for the Sixth Circuit (Sixth Circuit or Court) to remand without vacatur EPA's removal of the ANR from the Ohio SIP. Because the Court did not vacate EPA's removal of the ANR, the ANR is currently not in Ohio's SIP. After reevaluating EPA's November 19, 2020, rulemaking, upon remand, EPA proposed to determine that its November 2020 final action was in error, and to correct that action by reinstating the ANR as part of the Ohio SIP. EPA proposed to take this action on February 22, 2024 and received both supportive and adverse comments. EPA is finalizing this action as proposed, and upon the effective date of this action, the ANR will be reinstated into the Ohio SIP.
Learn More🌍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🌍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🔥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).
