The EPA’s Office of Air and Radiation (OAR) has requested the SAB to review EPA’s draft air emission
estimating methodologies (EEMs) for animal feeding operations (AFOs). EPA developed the draft methodologies to address requirements of a voluntary air compliance consent agreement signed in 2005 between EPA and nearly 14,000 broiler, dairy, egg layer, and swine AFO operations. The goals of the agreement are to reduce air pollution, monitor AFO emissions, promote a national consensus on methodologies for estimating emissions from AFOs, and ensure compliance with the requirements of the Clean Air Act (CAA), the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the Emergency Planning and Community Right-to-Know Act (EPCRA).
