Air Quality Regulations

In 1970, Congress passed the Clean Air Act (CAA) to give the United States Environmental Protection Agency (EPA) the authority to clean the air. Major revisions to the Clean Air Act occurred in 1990, and are referred to as the Clean Air Act Amendments (CAAA).

The EPA works with states and the District to implement the CAA and CAAA by developing regulations and programs. The District's regulations are at least as stringent, and sometimes more stringent, than requirements imposed by the EPA. 

The following are enacted under the District's Air Pollution Control Act of 1984 (effective March 15, 1985) and Amendments, and can be found in Title 20 of the District of Columbia Municipal Regulations (DCMR) as outlined below:

A record of the history of changes to the District's air quality laws and regulations since they were established in 1984, as approved by EPA in the District’s State Implementation Plan (SIP), can found in Title 40, Subpart J of the Code of Federal Regulations (CFR).
