The Environmental Protection Agency (EPA) inspected Double V Dairy near Rock Valley, Iowa in March and May 2013.
EPA inspections and sampling documented that Double V Dairy discharged manure into Rogg Creek and its tributaries while it owned the dairy between 2010 and 2013.
The manure discharges originated from stockpiles of used bedding sands that were stored outside in an uncontrolled area.
“Producers should regularly evaluate all aspects of their operations to ensure they are not discharging into nearby rivers and streams,” said EPA Regional Administrator Karl Brooks.
“Even if livestock or poultry is confined indoors, producers still need to manage their outdoor areas.”
Under Double V Dairy, it had the capacity for 1,200 dairy cattle. It was sold in November 2013 and is in operation today.
