In 1970, Congress passed the Clean Air Act (CAA) to give the United States Environmental Protection Agency (EPA) the authority to clean the air.  EPA works with states and the District as co-regulators to implement the CAA and subsequent CAA amendments (CAAA).

The District of Columbia Air Pollution Control Act of 1984 was established to “develop a comprehensive program for the control and prevention of air pollution in the District.”  The Act was replaced with the Air Quality Amendment Act of 2014.  The following air quality regulations implement the District’s air quality control law.
