Home » Resources » Funding and Project Resources » Congestion Mitigation & Air Quality

Congestion Mitigation & Air Quality (CMAQ) is a federal program started in 1991 under the Intermodal Surface Transportation Efficiency Act (ISTEA) and continues under the current transportation funding legislation, Fixing America’s Surface Transportation (FAST) Act. The program’s purpose is to fund projects that help achieve compliance with the national air quality standards established under the Clean Air Act. CRTPO’s planning area was designated as “maintenance” for ozone by the Environmental Protection Agency in August 2015. Any project proposed for CMAQ funding must be able to demonstrate that its implementation will contribute to a reduction in harmful emissions.

CMAQ funds are programmed per the CRTPO’s Discretionary Grants Program Policy Guide.
