Region 6 CAFO Program

cows, sheep, horses, chicken

Concentrated Animal Feeding Operations (CAFOs) are agricultural operations where animals are kept and raised in confined situations. Manure and wastewater from CAFOs have the potential to contribute pollutants such as nitrogen and phosphorus, organic matter, sediment, pathogens, heavy metals, hormones, antibiotics, and ammonia to the environment. Animal waste can enter water bodies from spills or breaks of waste storage structures, due to accidents or excessive rain, and non-agricultural application of manure to crop land.

The NPDES program regulates the discharge of pollutants from CAFOs to waters of the United States. EPA Region 6 directly implements the CAFO program in Oklahoma and New Mexico. The states of Arkansas, Louisiana and Texas have been authorized by EPA to implement the CAFO program in their respective states. EPA acts in an oversight and technical assistance role for these state programs.

For information concerning compliance assurance and enforcement of federal CAFO regulations in Region 6, please contact Dr. Abu Senkayi, EPA Region 6 Compliance Assurance and Enforcement Division, at (214) 665-8403 or visit the Region 6 Water Enforcement CAFO webpage.
