Land Application Setback and Buffer Requirements for NPDES Permitted Large CAFOs

Large Concentrated Animal Feeding Operation (CAFO) owners/operators are required to implement setbacks, buffers, or an alternative conservation practice on all fields to which manure is applied. This newsletter discusses the federal rules and some guidance on how the rule may be applied to land application sites. The setbacks and buffer requirements apply to large CAFOs only. Most states are authorized to implement the CAFO program and may have additional, more stringent requirements. Check with your state permitting authority to determine the requirements that apply to your operation.
