NPDES Missouri Animal Feeding Operations – Animal Unit, Type

In Data News, 2019-08-26

Animal Feeding Operations (AFOs) are agricultural operations where animals are kept and raised in confined situations. An AFO is a lot or facility (other than an aquatic animal production facility) where the following conditions are met:

animals have been, are, or will be stabled or confined and fed or maintained for a total of 45 days or more in any 12-month period, and
crops, vegetation, forage growth, or post-harvest residues are not sustained in the normal growing season over any portion of the lot or facility.

AFOs that meet the regulatory definition of a concentrated animal feeding operation (CAFO) are regulated under the NPDES permitting program. The NPDES program regulates the discharge of pollutants from point sources to waters of the United States.
