## Abstract

EPA is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Virginia. This SIP revision consists of a demonstration that the Virginia portion (Cities of Alexandria, Fairfax, Falls Church, Manassas, and Manassas Park; Counties of Arlington, Fairfax, Loudon, and Prince William) of the Washington, DC-MD-VA 8-Hour Ozone Nonattainment Area meets the requirements of reasonably available control technology (RACT) for oxides of nitrogen (NO<INF>X</INF>) and volatile organic compounds (VOCs) set forth by the Clean Air Act (CAA). These requirements are based on: Certification that previously adopted RACT controls in Virginia's SIP that were approved by EPA under the 1-hour ozone national ambient air quality standard (NAAQS) are based on the currently available technically and economically feasible controls, and that they continue to represent RACT for the 8-hour implementation purposes; a negative declaration demonstrating that no facilities exist in the Virginia portion of the Washington, DC-MD-VA area for certain control technology guideline (CTG) categories; and a new RACT determination for a specific source. This action is being taken under the CAA.
