The Congestion Mitigation and Air Quality (CMAQ) Improvement Program is part of the Competitive Programs that East-West Gateway Council of Governments (EWG) administers. CMAQ projects, like all federally funded transportation projects, are included in the Transportation Improvement Program that EWG develops for the St. Louis region. The CMAQ program provides a flexible funding source to State and local governments for transportation projects and programs to help meet the requirements of the Clean Air Act. Funding is available to reduce congestion and improve air quality for areas, including the St. Louis region, that do not meet the National Ambient Air Quality Standards for ozone, carbon monoxide, or particulate matter (nonattainment areas) and for former non-attainment areas that are now in compliance (maintenance areas). This program is authorized by the current transportation law the Fixing America’s Surface Transportation (FAST) Act.
CMAQ funds can be used for projects such as:
- Traffic flow improvements
- Demand management
- Shared ride services
- Bicycle and pedestrian facilities
- Transit vehicles/facilities
- Operating assistance for new transit projects
CMAQ funds cannot be used for routine maintenance such as roadway resurfacing/reconstruction and projects that add new single occupant vehicle capacity vehicles.
CMAQ funds are available to eligible Illinois and Missouri sponsors in the jurisdictions in the St. Louis region.
Eligible applicants include:
- A municipality
- A county
- A state
- Bi-State Development/Metro
