Colorado River Basin - Concentrated Animal Feeding Operation (CAFO) Permit
Title 40 CFR 122.23 defines a concentrated animal feeding operation (CAFO) as any animal feeding operation that has more than 1,000 animal units (dairy cattle are considered 1.4 animal units and feeder cattle are considered 1animal unit). Pursuant to the Clean Water Act (CWA), all CAFOs are point sources and are subject to NPDES permitting requirements. Smaller animal feeding operations can also be designated as CAFOs by the permitting agencies after considering certain criteria cited under Title 40 CFR 122.23 (b)(1).
The Regional Board has determined that all feedlots, dairies, heifer ranches, calf nurseries and other similar facilities in the Region shall be designated as CAFOs.
The proposed draft for the General Order will update requirements needed to comply with USEPA regulations for CAFOs.
