A northwest Iowa dairy has settled a federal lawsuit and promises action to prevent future manure discharges into nearby streams.

Prosecutors also said Thursday that Meadowvale Dairy, of Rock Valley, has agreed to pay a $160,000 civil penalty. The proposed consent decree is subject to a 30-day public comment period and approval by the federal court.

The lawsuit filed last February alleges that since 2001, Iowa has cited Meadowvale a dozen times for failures to maintain adequate storage for effluent.

The complaint says Meadowvale operates waste systems for two interconnected feeding operations for a total of about 10,000 head of cattle. It says wastewater from two of Meadowvale's facilities entered two tributaries of the Big Sioux River in violation of the dairy's National Pollutant Discharge Elimination System permits.
