Where Do I Get My CAFO Permits?

If a CAFO plans construction activities that disturb more than one acre of land, a stormwater permit during construction is also needed.

• For most CAFOs, the NPDES permit and the stormwater construction permit will be issued by the state that the CAFO is located in. For information on how to obtain these permits, please contact the appropriate state agency below:
State CAFO contacts

• If a CAFO is on Indian Country (see map of tribal lands), you will need to obtain both the NPDES permit and the stormwater construction permit from EPA.
