Congestion Mitigation and Air Quality

The CMAQ program provides federal funding for transportation projects and programs to help meet the requirements of the Clean Air Act.

Congestion Mitigation and Air Quality (CMAQ) funding is available to reduce congestion and improve air quality for areas that do not meet the National Ambient Air Quality Standards for ozone, carbon monoxide, or particulate matter (PM) (nonattainment areas) and for former nonattainment areas that are now in compliance (maintenance areas). A nonattainment area is an area considered to have air quality worse than the National Area Air Quality Standards as defined in the federal Clean Air Act Amendments.

Funds are allocated to the following Metropolitan Planning Organizations (MPOs): Puget Sound Regional Council, Southwest Washington Regional Transportation Council, Spokane Regional Transportation Council, Thurston Regional Planning Council, and Yakima Valley Conference of Governments. By agreement of these MPOs, allocations are calculated using distribution percentages from 2012. In addition to this distribution, the Puget Sound Regional Council also receives a set-aside allocation of PM2.5 funds.
