What the agency says

The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the Department of Energy and Environment (DOEE) on behalf of the District of Columbia (DC). The revision pertains to creating a synthetic minor permit program and resolving the regulatory differences between DC's current regulations and those regulations approved previously in Chapters 1 and 2 of the Air Quality Regulations codified in title 20 of the District of Columbia Municipal Regulations (DCMR). The intended effect of this action is to enable DC to create federally enforceable synthetic minor permit conditions for sources of criteria pollutants. The EPA is approving these revisions to the DC SIP in accordance with the requirements of the Clean Air Act (CAA).
