Procedures & Services

DDOT Environmental Manual, Chapter 14: Air Quality Policy and Regulations

The Congestion Mitigation and Air Quality Improvement (CMAQ) program provides a flexible funding source for State and local governments to fund transportation projects and programs to help meet the requirements of the Clean Air Act (CAA) and its amendments. The legislation is codified at 23 USC Sec 149. CMAQ money supports transportation projects that reduce mobile source emissions in areas designated by the U.S. Environmental Protection Agency (EPA) to be in nonattainment or maintenance of the national ambient air quality standards. Since its beginning in 1992, the CMAQ program has provided more than $30 billion for over 29,000 transportation-related emission reduction projects for State transportation departments (DOTs), metropolitan planning organizations (MPOs), and other sponsors across the country. Local CMAQ projects include Metropolitan Branch Trail - Fort Totten, Long Bridge Pedestrian & Bicycle Connection, and more. 

The District Department of Transportation (DDOT) is a voting member of the Clean Air Partners (CAP), which is a partnership established by the Metropolitan Washington Council of Government and the Baltimore Metropolitan Council.
