# FOR FURTHER INFORMATION CONTACT:

                        Mr. Larry Elmore, Natural Resources Group, Sector Policies and Programs Division, (E143-03), Environmental Protection Agency, Research Triangle Park, NC 27711; telephone number: (919) 541-5433; Facsimile number: (919) 541-3470; email address:                         *elmore.larry@epa.gov.*

# SUPPLEMENTARY INFORMATION: 

                    In January 2005, the EPA announced the voluntary Air Compliance Agreement (Agreement) with the animal feeding operations (AFO) industry. Under the Agreement, participating AFOs were responsible for funding the National Air Emissions Monitoring Study (NAEMS)—a 2-year study of animal confinement structures and manure storage and treatment units in the broiler chicken, egg-layer, swine and dairy industries. The study's purpose was to gather emissions data that the EPA could use to develop emissions estimating methodologies (EEMs). To provide a framework for the NAEMS, AFO industry experts, university and government scientists, and other stakeholders collaborated to develop a comprehensive monitoring plan. The study was designed to generate scientifically credible data to characterize emissions from the participating animal sectors. The                           ( print page 14717)                        NAEMS began in the summer of 2007 and consisted of 24 monitoring sites located in nine states. In addition, Tyson Foods, Inc. collected data from two broiler sites, which are also included in the NAEMS dataset. Academic researchers from various universities conducted the NAEMS study with EPA oversight. At the animal confinement sites, the study was designed to collect process and emissions data for ammonia (NH3), hydrogen sulfide (H2                    S), total suspended particulate matter (TSP), particulate matter with aerodynamic diameters less than 10 micrometers (PM10), PM with aerodynamic diameters less than 2.5 micrometers (PM2.5), and volatile organic compounds (VOCs). For lagoons and basins, the study was designed to collect NH3, H2                    S and VOCs.                 

In accordance with the Agreement's monitoring protocol, the EPA developed draft EEMs for animal housing structures and manure storage and treatment units using the emissions and process data collected under the NAEMS and other relevant information. Once the draft EEMs are final, the EPA expects that the AFO industry will use the EEMs to estimate daily and annual emissions for use in determining AFOs' regulatory responsibilities under the Clean Air Act, the Comprehensive Environmental Response, Compensation and Liability Act, and the Emergency Planning and Community Right-to-Know Act. 

The draft documents describe the sites monitored, the statistical methodology used to analyze the data, and the EEMs. 

                    The agency is requesting comment on the draft documents with particular emphasis on the statistical methodology used to develop the emissions estimating methodologies. Please submit comments within 90 days of the date of this notice. Electronic copies of the documents are available at                     *www.epa.gov/​airquality/​agmonitoring*.                 

On February 17, 2012, EPA's Office of Air Quality Planning and Standards sent a memorandum to the EPA Science Advisory Board Staff Office titled, “Animal Feeding Operations Air Emissions Estimating Methodologies from the National Air Emissions Monitoring Study” asking the Science Advisory Board to review and provide comments on these documents. 

                    In response to EPA's memorandum, the EPA's Science Advisory Board has formed an expert panel to review and provide comments on these documents. The Science Advisory Board review process is an independent process. Information on submitting comments to the Science Advisory Board can be found at                     *www.epa.gov/​sab*. Additional information about the Science Advisory Board process can be found at:                     *http://yosemite.epa.gov/​sab/​sabproduct.nsf/​0/​ae6639dd6b79360e852579a4004e5529!OpenDocument.*                     The Science Advisory Board anticipates multiple meetings of the expert panel to cover the documents in this notice.                 

The EPA will consider public comments received in response to this notice, public comments submitted to the Science Advisory Board, and the Science Advisory Board panel recommendations as the final emissions estimating methodologies are developed. 

Dated: February 29, 2012.

Acting Assistant Administrator.
