In 2003, EPA introduced revised Clean Water Act regulations to better protect surface waters from nutrients from concentrated animal feeding operations (CAFOs). When applying manure to crop or pasture land (the primary disposal method), CAFOs now must follow a nutrient management plan that specifies a manure application rate that minimises the threat to water quality. This book focuses on managing manure to improve air and water quality; trends and developments in hog manure management; and current laws and legislative issues with animal waste and hazardous substances.
