🌫️Wyoming EPA Approves Air Quality Regulation for Jim Bridger Units
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Wyoming on December 30, 2022, and supplemented on August 31, 2023, and November 16, 2023, addressing regional haze for Jim Bridger Units 1 and 2 (Wyoming 2022 SIP revision). Wyoming's 2022 SIP revision provides oxides of nitrogen (NO<INF>X</INF>) emission and heat input limits that collectively allow for identical reasonable progress as part of the long term strategy during the first implementation period as the associated emission limits in the existing SIP for Jim Bridger Units 1 and 2. The EPA is also approving monthly and annual NO<INF>X</INF> and sulfur dioxide (SO<INF>2</INF>) emission limits for Jim Bridger Units 1 through 4 that were included in Wyoming's 2022 SIP revision. The EPA is taking this action pursuant to the Clean Air Act (CAA or the Act).

The Environmental Protection Agency (EPA) is determining that Indian country under the jurisdiction of the Shinnecock Indian Nation located within the New York-Northern New Jersey-Long Island nonattainment area (Shinnecock Indian Nation area) failed to attain the 2015 ozone National Ambient Air Quality Standards (NAAQS) by the applicable attainment date. The effect of failing to attain by the applicable attainment date is that the area will be reclassified by operation of law to "Serious" nonattainment for the 2015 ozone NAAQS on September 2, 2025, the effective date of this final rule. This action fulfills the EPA's obligation under the Clean Air Act (CAA) to determine whether ozone nonattainment areas attained the NAAQS by the attainment date and to publish a document in the Federal Register identifying each area that is determined as having failed to attain and identifying the reclassification.

The Environmental Protection Agency (EPA) is proposing to approve, under the Clean Air Act (CAA), the limited maintenance plan (LMP) for the 2006 PM<INF>2.5</INF> national ambient air quality standard (NAAQS) for the New Jersey portion of both of New Jersey's multi-state maintenance areas: the Northern New Jersey portion of the New York-Northern New Jersey-Long Island, NY-NJ-CT (Northern New Jersey) maintenance area and the New Jersey portion of the Philadelphia-Wilmington, PA-NJ-DE (Southern New Jersey) maintenance area. This LMP was submitted on July 6, 2023, and supplemented on June 6, 2024, by the New Jersey Department of Environmental Protection (NJDEP). The plan addresses the second 10-year maintenance period for particulate matter with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers, known as PM<INF>2.5</INF>. The EPA is proposing approval of New Jersey's LMP submission because it provides for the maintenance of the 2006 24-hour PM<INF>2.5</INF> NAAQS through the end of the second 10-year portion of the maintenance period. In addition, the EPA completed the adequacy review process of this New Jersey PM<INF>2.5</INF> LMP for transportation conformity purposes on June 7, 2024.

Learn More🚗Rhode Island's Motor Vehicle Inspection Program Amendments Proposal
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the Rhode Island Department of Environmental Management Office of Air Resources on December 20, 2023, that includes an amended regulation for the Enhanced Motor Vehicle Inspection and Maintenance (I/M) program in Rhode Island. Overall, the submittal removes obsolete references, adds definitions, and clarifies the Rhode Island I/M program requirements, which consist primarily of conducting Onboard Diagnostics (OBD) testing. The intended effect of this action is to propose approval of the State's amended I/M program regulation into the Rhode Island SIP. This action is being taken under the Clean Air Act (CAA). EPA has evaluated the SIP revision and has preliminarily determined the changes will not impact emissions under the Rhode Island I/M program. EPA is proposing to conclude that approval of the SIP revision will not interfere with attainment or maintenance of any National Ambient Air Quality Standard (NAAQS) or with any other applicable requirement of the CAA. Therefore, EPA is proposing to determine that Rhode Island's December 20, 2023, SIP revision is consistent with the applicable provisions of the CAA.

The Environmental Protection Agency (EPA) is proposing to approve a revision to the State of New York's State Implementation Plan (SIP) for the ozone National Ambient Air Quality Standard (NAAQS) related to a source-specific SIP (SSSIP) revision for Ortho Clinical Diagnostics, 513 Technology Boulevard, Rochester, New York (the Facility). The EPA is proposing to find that the control options in this SSSIP revision implement Reasonably Available Control Technology (RACT) with respect to volatile organic compound (VOC) emissions from the relevant Facility source, which are identified as one solvent-based film coating machine. This SSSIP revision is intended to implement VOC RACT for the relevant Facility source in accordance with the requirements for implementation of the 2008 and 2015 ozone NAAQS. EPA proposes to determine that this action will not interfere with ozone NAAQS requirements and meets all applicable requirements of the Clean Air Act (CAA).
