Grain Processing Corporation (GPC) in Muscatine has agreed to pay a $129,000 fine for violations of the federal Clean Water Act that occurred in 2011, the U.S. Environmental Protection Agency (EPA) announced today (4/16).
"GPC failed to comply with its National Pollutant Discharge Elimination System (NPDES) monitoring requirements by taking unrepresentative flow measurements and not conducting settleability tests; failed to maintain all facilities and control systems in good working order; and exceeded the effluent limitations for biochemical oxygen demand, total suspended solids, temperature, and pH," according to the EPA news release. "GPC came into compliance with Clean Water Act regulations after EPA Region 7 issued an order to the company on July 29, 2011, requiring it to correct the violations."
The effluent violations negatively impacted the Mississippi River, according to the EPA. The operations and maintenance violations, which included malfunctioning equipment and failure to comply with monitoring requirements, led to wastewater pollutants being released into the river which are not accurately known or documented.
