Congestion Mitigation and Air Quality (CMAQ) Improvement Program

The CMAQ Program provides funding to state departments of transportation (DOTs), local governments, and transit agencies for projects and programs that help meet the requirements of the Clean Air Act by reducing mobile source emissions and regional congestion on transportation networks. Eligible activities include transit improvements, travel demand management strategies, congestion relief efforts (such as high occupancy vehicle lanes), diesel retrofit projects, and alternative fuel vehicles and infrastructure. Projects supported with CMAQ funds must demonstrate emissions reductions, be located in or benefit a U.S. Environmental Protection Agency-designated nonattainment or maintenance area, and be a transportation project. For more information, see the FAST Act CMAQ fact sheet and CMAQ Improvement Program website. (Reference Public Law 112-141, 23 U.S. Code 149, and 23 U.S. Code 151)
