Congestion Mitigation & Air Quality


Congestion Mitigation & Air Quality (CMAQ) is a federal program begun 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

Call for Projects:

When CMAQ funding becomes available, a call for projects is sent to CRTPO member agencies and local jurisdictions. An application must be completed for each project. Projects submitted for consideration are reviewed and ranked by a selection committee of technical staff. Upon completion of the ranking process, the project list (and proposed funding) is submitted to the Metropolitan Planning Organization (MPO) for approval.
