Iowa Clean Air Attainment Program

Iowa Clean Air Attainment Program

The purpose of Iowa’s Clean Air Attainment Program (ICAAP) is to help finance transportation projects and programs that improve air quality.

Specifically, the intent of ICAAP funding is to attain or maintain the national ambient air quality standards (NAAQS) of the 1990 Clean Air Act Amendments (CAAA) with a focus on volatile organic compounds (VOC) and nitrogen oxides (NOx), carbon monoxide (CO) and, under certain conditions, particulate matter (PM-2.5 and PM-10). VOC and NOx contribute to ground-level ozone (O3) formation.

Each year, the MPO Policy Committee reviews and approves the ICAAP applications of MPO member governments. Then, the Iowa Department of Transportation awards ICAAP funds to projects and programs with the highest potential for reducing transportation-related congestion and air pollution, thereby maintaining Iowa’s clean air quality.
