Iowa Clean Air Attainment Program (ICAAP)
The purpose this program is to help finance transportation projects and programs that result in attaining or maintaining 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. ICCAP funds are awarded to projects and programs with the highest potential for reducing transportation-related congestion and air pollution, thereby maintaining Iowa’s clean air quality. Proposals must have a minimum total project cost of $20,000 to be eligible. The federal funding share for most projects is 80 percent of the proposed cost but the federal funding share for programs on the interstate highway system is 90 to 100 percent. Sponsors must provide local matching funds and these funds cannot be in the form of volunteer or in-kind services or federal funds. However, state funds may be used as the local share unless prohibited by law.
