Concentrated Animal Feeding Operations (CAFOs)

Concentrated Animal Feeding OperationAn Animal Feeding Operation (AFO) is a facility that stables, confines and feeds or maintains animals (other than aquatic animals) for a total of 45 days or more in any 12-month period and does not sustain crops, vegetation, forage growth, or post-harvest residues in the normal growing season. An AFO becomes a Concentrated Animal Feeding Operation (CAFO) when it meets either the large (Class I) or Medium (Class II) size threshold (see Table 1 below), or has been designated as a CAFO by the Tennessee Department of Environment and Conservation (TDEC). If your operation meets the criteria of a CAFO, you will need to obtain a permit from TDEC. Through a Memorandum of Agreement, TDA reviews CAFO permit applications on behalf of TDEC. Once approved, TDEC issues the permit. Additional information on obtaining a CAFO permit can be found below.
