THE NATIONAL ACADEMIES

National Academy of Sciences

National Academy of Engineering

Institute of Medicine

National Research Council

The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences.

The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering.

The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Kenneth I. Shine is president of the Institute of Medicine.

The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chairman and vice chairman, respectively, of the National Research Council.

Preface

This is an interim report of the ad hoc Committee on Air Emissions from Animal Feeding Operations of the National Research Council’s Committee on Animal Nutrition. A final report is expected to be issued by the end of 2002. The interim report is intended to provide the committee’s findings to date on assessment of the scientific issues involved in estimating air emissions from individual animal feeding operations (swine, beef, dairy, and poultry) as related to current animal production systems and practices in the United States. The committee’s final report will include an additional assessment within eight broad categories: industry size and structure, emission measurement methodology, mitigation technology and best management plans, short- and long-term research priorities, alternative approaches for estimating emissions, human health and environmental impacts, economic analyses, and other potential air emissions of concern.

This interim report focuses on identifying the scientific criteria needed to ensure that estimates of air emission rates are accurate, the basis for these criteria in the scientific literature, and uncertainties associated with them. It also includes an assessment of the emission-estimating approaches in a recent U.S. Environmental Protection Agency (EPA) report Air Emissions from Animal Feeding Operations (EPA, 2001a). Finally, it identifies economic criteria needed to assess emission mitigation techniques and best management practices.

The committee held three meetings in preparing this interim report and developing material for its final report. People knowledgeable about air emissions issues, including representatives of EPA, the U.S. Department of

Agriculture (USDA), academia, the animal feeding industry, and the public, presented relevant information at each of the meetings, which were held in Washington, D.C., Durham, North Carolina, and Denver, Colorado. Field visits to animal feeding operations were also conducted. The committee also reviewed various peer-reviewed and non-peer-reviewed literature describing the issues, the science that lies behind methods for measuring and estimating emissions, and materials prepared by and for EPA and USDA.

The committee relied on the expertise and knowledge of its members, who represent a range of disciplinary backgrounds, including epidemiology and biostatistics, environmental engineering, atmospheric and tropospheric chemistry, biogeochemistry, environmental sciences, agricultural law, animal nutrition, agricultural engineering, soils and physical chemistry, microbiology, agricultural and resource economics, emission measurement and characterization, and biological engineering.
