COUNCIL BLUFFS, Iowa (AP) — Environmental officials say a pipe company must pay $950,000 for air and water violations at its former Council Bluffs facility. The U.S. Environmental Protection Agency’s Region 7 says Griffin Pipe Products must pay the civil penalty after multiple violations.

The company is accused of illegally discharging untreated process wastewater to the city’s wastewater collection system between 2007 and 2008. It is also accused of violating its storm water permit in 2011. The EPA says the company also discharged zinc, lead, copper and other pollutants in violation of its permit levels.

Griffin Pipe Products has ceased production at the Council Bluff facility. It says it is now in compliance with the Clean Air Act and the Clean Water Act.
