Air Emissions Monitoring Study for Animal Feeding Operations (AFOs)

EPA collaborates with farmers on the first-ever nationwide study of air emissions from animal feeding operations (AFOs). Researchers from eight universities will take part in a two-year, $14.6 million study to measure levels of hydrogen sulfide, particulate matter, ammonia, nitrous oxide, volatile organic compounds, and other gases from poultry, dairy, and swine facilities at 24 sites in nine states as part of an innovative and voluntary consent agreement EPA developed with the AFO industry. This agreement established a framework for farmers to participate in a monitoring study in which over 2,600 agreements were signed, representing approximately 14,000 swine, dairy, egg-laying, and broiler chicken (meat-bird) farms (an AFO can include more than one farm).

Air Quality Compliance Agreement for Animal Feeding Operations

On January 21, 2005, EPA announced an air quality compliance agreement to address emissions from certain animal feeding operations, also known as AFOs. The primary goals of the Air Quality Compliance Agreement are:

New Source Performance Standards and Emission Guidelines

New Source Performance Standards and Emission Guidelines for Existing Sources: Other Solid Waste Incineration Units (OSWI) - EPA is proposing new source performance standards and emission guidelines for new and existing "other" solid waste incinerators units. EPA describes the categories: (3) agricultural waste incinerators, (4) wood waste incinerators and (6) crematories (including livestock, poultry) in the rule; however, none of these three categories were included by EPA as a subcategory of Other Solid Waste Incinerators (OSWI) for regulation at this time.

Reporting Requirements for Air Releases

Final Mandatory Greenhouse Gas Reporting Rule
On September 22, 2009, EPA finalized a national system for reporting emissions of carbon dioxide and other greenhouse gases produced by major sources in the United States. Under the Mandatory Reporting of Greenhouse Gases (GHGs) rule, owners or operators of facilities that contain manure management systems, and emit at least 25,000 metric tons of GHGs per year (expressed as carbon dioxide equivalents) will report emissions from all source categories located at the facility for which emission calculation methods are defined in the rule. Owners or operators will collect emission data; calculate GHG emissions; and follow the specified procedures for quality assurance, missing data, recordkeeping, and reporting.

Rule Change Provides Exemptions from Reporting Requirements for Air Releases of Hazardous Substances from Farm Animal Waste
EPA has finalized a rule providing a full exemption for reporting air releases of hazardous substances from animal waste at farms to the federal government and a partial exemption of reporting the releases to state and local governments. This new rule exempts all farms from reporting air releases under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The new rule requires only large animal feeding operations to report certain types of releases to local and state agencies, as directed by the Emergency Planning and Community Right-to-Know Act (EPCRA).
