🌬️EPA Proposes Changes to Alabama’s Air Quality Regulations

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Alabama, through the Alabama Department of Environmental Management (ADEM) on December 20, 2023. The revision modifies the State's air quality regulations as incorporated into the SIP by changing the definition of "volatile organic compounds" (VOC) to be consistent with Federal regulations. The revision also addresses typographical errors and increases clarity and consistency with EPA's definitions and Alabama's Legislative Services Agency requirements.

🌍New Jersey Air Quality Regulation Compliance Implications for Businesses

The Environmental Protection Agency (EPA) is approving a revision to New Jersey's State Implementation Plan (SIP), submitted by the New Jersey Department of Environmental Protection (NJDEP), for the purposes of incorporating regulations concerning permits and certificates for minor source facilities, and major source facilities without an operating permit. The intended effect of the NJDEP's revisions to the SIP is to regulate the construction and modification of stationary sources with adequate requirements to ensure that the National Ambient Air Quality Standards (NAAQS) are satisfied. The NJDEP's revisions will strengthen the SIP by updating the Federal air permitting program to conform with the State regulations that were in effect at the time of the SIP submission, which will ultimately better serve the regulated community and help to protect the quality of air in the State. The EPA proposed to approve this rule on December 17, 2024, and received no comments.

🌍EPA Reinstates Ohio Air Nuisance Rule

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.

🌍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.

🌍EPA Defers Sanctions for San Joaquin Valley Air Pollution Compliance

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.
