Iowa Clean Air Attainment Program

Iowa Clean Air Attainment Program

Modeled after the federal Congestion Mitigation and Air Quality Improvement Program, Iowa’s Clean Air Attainment Program (ICAAP) was created by the Iowa Department of Transportation (DOT) in 1994. The purpose of ICAAP is to provide funds to transportation projects that maintain the national ambient air quality standards outlined in the 1990 Clean Air Act Amendments.

Each year, the Iowa DOT awards ICAAP funds to projects with the highest potential for reducing transportation-related congestion and air pollution.

Applications for ICAAP are available at the Iowa DOT’s ICAAP website
