Congestion Mitigation and Air Quality (CMAQ) is a federal funding source created to assist areas in attaining or maintaining air quality standards under the Clean Air Act, by reducing mobile transportation emissions. In Michigan, the CMAQ program is administered by the Michigan Department of Transportation (MDOT).
All CMAQ projects must meet three eligibility requirements:
· Have a transportation focus
· Reduce air emissions
· Be located in or benefits a non-attainment or maintenance area
