Comparison: State vs. Federal

Rules. Mississippi has received authority from the U.S. Environmental Protection Agency (EPA) to administer the federal National Pollutant Discharge Elimination System (NPDES) permit program for point source wastewater discharges that include discharges from concentrated animal feeding operations (CAFOs). See the national section AG WASTE for more information on the federal CAFO definitions and requirements.

The state expands on federal rules by regulating animal feeding operations (AFOs) that are smaller than EPA's CAFO definition. The DEQ requires state permits for AFOs with 10 or more sows or 50 or more swine animal units. See the national section AG WASTE for additional information.

Mississippi also requires that CAFOs with NPDES permits apply for air permits, and issues multimedia permits that address federal and state requirements for both air and water.
