EDDYVILLE, Iowa (AP) — Cargill Inc. has agreed to pay more than $187,000 to settle allegations that it violated the Clean Water Act at large oil storage facilities in Iowa and Nebraska.

The U.S. Environmental Protection Agency’s Region 7 says the privately held multinational corporation lacked a response plan at two facilities that outlined procedures for addressing serious oil discharges.

The facilities are located in Blair, Nebraska, and Eddyville, Iowa. Each facility produces and stores more than one million gallons of oil.

The EPA identified the issue during site visits in 2013. The Minnesota-based company submitted response plans in June 2014.
