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 plan for the Charleston area. 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 plan continues 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 plan for Charleston in accordance with the requirements of the Clean Air Act (CAA).
