Comparison: State vs. Federal
• Rules. In addition to federal permit requirements for dredge and fill permits in wetland areas, Iowa administers permit programs for conserving and protecting the state's water, recreational, and environmental resources, and for the prevention of damage to state floodplains. Iowa also has jurisdiction over sovereign lands and waters and certain fee title lands.
• Administration and enforcement. The Iowa Department of Natural Resources (DNR) is responsible for the administration and enforcement of the state's water quality certification under the federal permit program, floodplain construction permits, construction permits, and special permit applications. The U.S. Environmental Protection Agency (EPA) Region 7 and the U.S. Army Corps of Engineers (Corps) administer and enforce the federal dredge and fill permit programs under the Clean Water Act. The Corps' three district offices in Rock Island and Omaha, Nebraska, are responsible for enforcing the wetland permit programs for various parts of Iowa.
