An Oregon dairy accused of dumping animal waste into the water is paying $12,000 in fines.
RSC Dairy in Tillamook has agreed to pay that amount to settle its violations.
The U.S. Environmental Protection Agency said the violations were discovered during an inspection in January 2010.
Investigators say animal waste was discharged from the dairy into Hall Slough, a tributary to the Wilson River, which flows into Tillamook Bay. RSC Dairy keeps around 500 cows at its Tillamook facility.
The EPA says samples of the waste showed a high concentration of E. coli bacteria. The agency adds that the dairy has taken steps to correct the situation.
