Approval and Promulgation of Air Quality Implementation Plans; District of Columbia; Reasonably Available Control Technology Under the 8-Hour Ozone National Ambient Air Quality Standard

EPA is approving a State Implementation Plan (SIP) revision submitted by the District of Columbia. This SIP revision consists of a demonstration that the District of Columbia meets the requirements of reasonably available control technology (RACT) for nitrogen oxides (NO<INF>X</INF>) and volatile organic compounds (VOCs) set forth by the Clean Air Act (CAA). This SIP revision demonstrates that all requirements for RACT are met either through: Certification that previously adopted RACT controls in the District of Columbia'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; and a negative declaration demonstrating that no facilities exist in the District of Columbia for the applicable control technology guideline (CTG) categories. This action is being taken under the CAA.
