The Environmental Protection Agency (EPA) is proposing to partially approve and partially disapprove certain elements of a State Implementation Plan (SIP) revision that New Jersey submitted to demonstrate that the State satisfies the infrastructure requirements of section 110(a)(1) and (2) of the Clean Air Act (CAA) for the 2015 8- hour Ozone National Ambient Air Quality Standards (NAAQS). The infrastructure requirements are designed to ensure that the structural components of each State's air quality management program are adequate to meet the State's responsibilities under the CAA. Except as noted, this SIP revision satisfies the infrastructure requirements of the CAA for the 2015 ozone NAAQS.

The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the Commonwealth of Virginia. This revision pertains to the Commonwealth's plan, submitted by the Virginia Department of Environmental Quality (VADEQ), for maintaining the 1997 8-hour ozone national ambient air quality standards (NAAQS) (referred to as the "1997 ozone NAAQS") in the Fredericksburg, Virginia Area (Fredericksburg Area). EPA is approving these revisions to the Virginia SIP in accordance with the requirements of the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is proposing to approve a revision to the North Carolina State Implementation Plan (SIP), submitted by the North Carolina Department of Environmental Quality (NCDEQ), Division of Air Quality, on December 19, 2022. The revision seeks to update the 2026 on-road and nonroad emissions inventories and safety margins, allocate a portion of the newly available 2026 safety margins in the 2008 8-hour Ozone Maintenance Plan to the 2026 nitrogen oxides (NOX) and volatile organic compounds (VOC) motor vehicle emissions budgets ("budgets") for the North Carolina portion of the Charlotte-Rock Hill, NC-SC bi-state Area (hereinafter referred to as the "North Carolina portion of the Charlotte Maintenance Area") to accommodate updates from the EPA Motor Vehicle Emissions Simulator (MOVES3) model. The SIP revision also revises the current 2026 budgets based on the MOVES3 updates and recalculates new available safety margins. NCDEQ's December 19, 2022, submission supplements the revised 2008 8-hour Ozone Maintenance Plan submitted by NCDEQ on July 16, 2020, and approved by EPA on August 25, 2021. EPA is proposing to approve North Carolina's December 19, 2022, SIP revision and deem the budgets adequate for transportation conformity purposes because they meet the applicable statutory and regulatory requirements.
