Air Quality

The Air Quality Division works to protect the health and welfare of District residents, visitors, and the natural environment by reducing the concentration of pollutants in the outdoor air. The Division issues permits, performs permit inspection and enforcement of laws, and monitors air quality while developing plans for its improvement.

Apply for an Air Pollutant Permit
The Division reviews designs and modifications for new and existing pollution sources and controls. Permits are issued allowing sources to emit limited amounts of pollution, meeting air quality laws.
