EPA is taking final action to remove codification of certain State Implementation Plan (SIP) approvals vacated by United States Court of Appeals for the District of Columbia Circuit and remanded to EPA. EPA is also concurrently vacating an indefinite stay, which EPA had issued pending completion of judicial review, of a conditional approval promulgated on April 17, 2003. These revisions relate to the 1-hour ozone attainment demonstration and the 1996-1999 rate-of- progress (ROP) plans for the Metropolitan Washington DC ozone nonattainment area (the Washington area) submitted by the District of Columbia's Department of Health (DoH), by the Maryland Department of the Environment (MDE) and by the Virginia Department of Environmental Quality (VADEQ), including enforceable commitments submitted by the District of Columbia, Virginia and Maryland as part of the 1-hour attainment demonstration. EPA is correcting the codification of the approval of these revisions in accordance with the requirements of the Clean Air Act.
