Environmental And Economic Benefit Analysis Of Final Revisions To The National Pollutant Discharge Elimination System Regulation And The Effluent Guidelines For Concentrated Animal Feeding Operations.
This report presents EPA's estimates of the environmental and human health benefits, including pollutant reductions, that will occur from the revisions to the NPDES regulations and effluent guidelines for concentrated animal feeding operations (CAFOs). The analysis focussed solely on benefits attributable to changes in regulations governing large CAFOs. Benefits were monetized for seven endpoints: (1) recreational and non-use benefits from improved water quality in rivers and streams, (2) reduced fish kills, (3) improved shellfish harvests, (4) reduced nitrate contamination of private wells, (5) reduced contamination of animal water supplies, (6) reduced public water treatment costs, and (7) potential recreational fishing benefits to the Albermarle-Pamlico Estuary (a partial benefits analysis of reduced eutrophication of estuaries and costal waters). Other non-monetized benefits include reduced pathogen contamination of private and public underground sources of drinking water, reduced human and ecological risks from antibiotics, hormones, metals, and salts, improved soil properties, and other benefits.
