The Environmental Protection Agency (EPA) is proposing approval of a revision to the District of Columbia State Implementation Plan (SIP) submitted by the District of Columbia (the District) through the District of Columbia Department of Energy and Environment (DOEE). The District's SIP revision addresses requirements of the Clean Air Act (CAA) and EPA's rules that require states to submit periodic reports describing progress towards reasonable progress goals (RPGs) established for regional haze and a determination of the adequacy of the state's existing SIP addressing regional haze (regional haze SIP). EPA is proposing approval of the District's SIP revision because EPA has determined that it satisfactorily addresses the progress report and adequacy determination requirements for the first implementation period for regional haze. This action is being taken under the CAA.
