Concentrated Animal Feeding Operation (CAFO)
Concentrated Animal Feeding Operation (CAFO)
The goal of the CAFO program is to reduce the discharge of pollutants to surface waters of the state from these types of facilities. A CAFO is an animal feeding operation that is regulated under the National Pollutant Discharge Elimination System (NPDES) permitting program. The NPDES program regulates discharges from point sources to surface waters, and under the Clean Water Act, CAFOs are considered point sources of pollution.
