Concentrated Animal Feeding Operation General Permit

About the permit

The Concentrated Animal Feeding Operation (CAFO) General Permit conditionally authorizes discharges to waters of the state from operations that confine and feed animals such as dairy and beef cows, poultry, horses, and pigs in concentrated areas. Those covered by the permit are required to manage the manure, litter, and process wastewater generated by the operation to protect water quality.

Updating the permit

Washington’s CAFO permit expired in 2011. We have been meeting with producers, environmental groups, agencies, legislators and tribes to solicit their concerns and input. The draft permit is a result of that engagement. Get involved >
