Concentrated Animal Feeding Operation General Permit

About the permit

The Concentrated Animal Feeding Operation (CAFO) permit requires large-scale livestock operations in Washington to implement specific practices to better protect groundwater, rivers, lakes and marine waters from manure pollution. It builds on the Department of Agriculture’s (WSDA) Dairy Nutrient Management Program. WSDA will continue as the principal inspector of dairies and will partner with Ecology to implement the permit.

Updating the permit

On January 18, 2017, we issued an updated water quality permit. The permit changes were based on substantial stakeholder and public feedback. Learn more >
