Iowa Clean Air Attainment Program (ICAAP)

Moving Ahead for Progress in the 21st Century Act (MAP-21), the current Federal Transportation Reauthorization Act, continued the Congestion Mitigation and Air Quality Improvement (CMAQ) Program. The CMAQ Program directs funds toward transportation projects helping meet the national ambient air quality standards in Clean Air Act nonattainment areas for ozone, carbon monoxide and particulate matter.

Indicative of the Congressional intent for creating the CMAQ Program, the Iowa DOT Commission established ICAAP in 1995. Iowa DOT administers the ICAAP on a statewide competitive application basis and awards federal funds to projects with the highest potential for reducing transportation-related congestion and air pollution. Project applications may be submitted by cities, counties, public transit agencies, and state and federal agencies. Private nonprofit organizations and individuals who want to apply for funding must have a public agency as a co-sponsor.

Proposed projects are evaluated and ranked by a project evaluation committee comprising representatives from the Iowa DOT's Office of Systems Planning, Iowa Department of Natural Resources, Iowa Public Transit Authority, MPOs, and RPAs. The Iowa DOT Commission has final project selection authority. Under MAP-21, Iowa DOT earmarked and administers $4.0 million of CMAQ funds annually for ICAAP.
