Air Plan Approval; NC; Removal of the State's Vehicle Inspection and Maintenance Program

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of North Carolina, through the North Carolina Division of Air Quality (NCDAQ), on October 1, 2024. The revision seeks to remove North Carolina's vehicle inspection and maintenance (I/M) program from North Carolina's SIP which covers 19 counties. EPA is proposing to approve this change as it will not interfere with any applicable requirement concerning attainment and reasonable further progress or any other applicable requirement of the Clean Air Act (CAA or Act).
