## Abstract

EPA is taking direct final action to approve a State Implementation Plan (SIP) revision submitted by the State of West Virginia. The revision amends the 8-hour ozone maintenance plans for the Charleston, Huntington, Parkersburg, Weirton, and Wheeling 8-hour ozone maintenance areas. This revision amends the maintenance plans' 2009 and 2018 motor vehicle emissions budgets (MVEBs) by reallocating a portion of the plans' safety margins which results in an increase in the MVEBs. The revised plans continue to demonstrate maintenance of the 8-hour national ambient air quality standard (NAAQS) for ozone. EPA is approving this SIP revision to the West Virginia maintenance plans for the Charleston, Huntington, Parkersburg, Weirton, and Wheeling 8-hour ozone maintenance areas in accordance with the requirements of the Clean Air Act (CAA).
