Managing Manure - New CAFO Guidance

EPA recently published, " Managing Manure at CAFOs." This document will help operators of Concentrated Animal Feeding Operations (CAFOs) and state and federal officials to understand and apply the February 2003 revised effluent limitations guidelines for CAFOs. This booklet provides detailed technical information including: determining if storage facilities are adequate to eliminate prohibited discharges from CAFO production areas; evaluating alternative technologies to determine if they eliminate production area discharges as effectively as a properly-sized lagoon; calculating manure application rates that minimize runoff from land application areas; ensuring that a Nutrient Management Plan incorporates the proper minimum standards; and evaluating alternatives to a 100-foot buffer strip to determine if they provide waters of the U.S. with equivalent protection from manure runoff.
