Revised CAFO Rules
On December 16th, 2002 the US Environmental Protection Agency
released it final ruling on the revised Confined Animal Feeding
Operations, CAFO, ruling. This EPA website contains a complete
guide to the revised rules:
Is my operation a CAFO?
Your operation is an animal feeding operation (AFO) if
- You confine animals for at least 45 days in a 12-month period and
- There 's no grass or other vegetation in the confinement area during the normal growing season
Your operation is a CAFO if
- It meets the definition of an AFO and
- The operation meets one of the following CAFO definitions
- Your operation is a Large CAFO if it has at least
- Your operation is a Medium CAFO if
- A man-made ditch or pipe carries manure or wastewater from your operation to surface water.
- Your animals come into contact with surface water running through the area where they 're confined
- And your operation has at least 200 mature dairy cows
- No matter what size your operation is, if it is an AFO, it may be designated a CAFO. If your permitting authority inspects your operation and finds that it 's adding pollutants to surface waters, you might need a NPDES permit.
