## Abstract

EPA is taking direct final action approving revisions to the District of Columbia State Implementation Plan (SIP). The revisions consist of portions of an operating permit which reduce sulfur dioxide (SO<INF>2</INF>) emissions from two steam-generating facilities located in the District of Columbia. The intent of this action is to approve, as SIP revisions, portions of the operating permit issued by the District of Columbia on October 17, 1997 to the General Services Administration (GSA) for its Central Heating and Refrigeration Plant and West Heating Plant in accordance with the requirements of the Clean Air Act (the Act).
