Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.

The purpose of this manual is to present a contemporary review of sludge processing technology and the specific procedures to be considered, modified, and applied to meet unique conditions. The manual emphasizes the operational considerations and interrelationship of the various sludge treatment processes to be considered before selecting the optimum design. The manual also presents case histories of existing wastewater treatment plants to illustrate the various unit processes and results.
