Congestion Mitigation and Air Quality Improvement (CMAQ) Program

The Congestion Mitigation and Air Quality (CMAQ) Improvement Program is a Federal program that funds transportation projects and programs that contribute to attainment or maintenance of the national ambient air quality standards (NAAQS) for ozone, carbon monoxide, and particulate matter. The CMAQ program supports the two goals of improving air quality and relieving congestion.

As a non-attainment/maintenance area for ozone and particulate matter, Connecticut receives Federal CMAQ Improvement Program funds based on the population in the non-attainment areas of the state and the severity of air quality problems.  As shown on the map below, the Capitol Region is part of the Greater Connecticut area, which is classified as marginal non-attainment for 2015 National Ambient Air Quality Standards (NAAQS) for Ozone.
