Abstract
EPA is taking direct final action to approve State Implementation Plan (SIP) revisions submitted by the State of West Virginia. The revisions amend the 1-hour ozone maintenance plans for Greenbrier County and the Charleston, Huntington and Parkersburg areas. These revisions amend the maintenance plans' base year and 2005 highway mobile volatile organic compound (VOC) and nitrogen oxide (NO<INF>X</INF>) emission inventories and the 2005 motor vehicle emissions budgets (MVEBs) to reflect the use of MOBILE6. These revisions also reallocate a portion of each plans' safety margins which results in an increase in the MVEBs. The revised plans continue to demonstrate maintenance of the 1-hour national ambient air quality standard (NAAQS) for ozone. EPA is approving these SIP revisions to the West Virginia maintenance plans in accordance with the requirements of the Clean Air Act.
