Animal Feeding Operations - An Overview
According to the USDA's Economic Research Service, animal products account for more than fifty percent of the value of U.S. agricultural products, exceeding $100 billion per year. The animals and animal products produced in animal feeding operations (AFOs) are a significant component of this $100 billion equation.
A number of legal, economic, and policy issues derive from the operation of AFOs. Issue areas include finance and credit, market concentration, production contracts, animal identification, animal welfare, the Packers and Stockyards Act, costs and benefits related to the impact of AFOs on natural resources and the environment, application of state and local zoning laws, and state nuisance laws.
Clean Water Act
The Clean Water Act (CWA) defines an "animal feeding operation" as a lot or facility, other than an aquatic animal production facility, where animals "have been, are, or will be stabled or confined and fed or maintained for a total of 45 days or more in any 12-month period." In addition, crops, vegetation, forage growth, or post-harvest residues cannot be sustained in the normal growing season over any portion of the lot or facility in order to be considered an AFO.
The CWA is a central figure in the regulation of animal feeding operations. In particular, the CWA requires Concentrated Animal Feeding Operations (CAFOs) to obtain a National Pollutant Discharge Elimination System Permits (NPDES) for their "point source" discharges of pollutants into the waters of the United States. CAFOs are a subset of AFOs, are "point sources" under the CWA, and are governed by specific regulations. The CWA similarly applies to "concentrated aquatic animal production facilities." The Environmental Protection Agency bears primary responsibility for implementing the CWA and its regulations. For a broader discussion of the CWA, please visit the Clean Water Act Reading Room.
Other Applicable Laws
Other federal statutes have also been implicated in the AFO context. These statutes include the Clean Air Act, the Comprehensive Environmental Response, Compensation and Liability Act, and the Emergency Planning and Community Right-to-Know Act. Each of these federal statutes are attended by extensive implementing regulations.
State and local laws may also impact the operation of AFOs. Common law actions under nuisance, trespass, or negligence theories have been associated with the operation AFOs. In addition, state and local land use provisions, zoning ordinances, and other similar measures have also been raised in the AFO context. For information concerning nuisance, land use, zoning ordinances, and related issues, please visit the Urban Encroachment Reading Room and the Landowner Liability Reading Room.
AFOs typically operate under legal arrangements referred to as production contracts. Under these contracts, the processor usually owns and supplies the animals raised by the producer. The contracts require the animals to be raised in accordance with instructions specified in the contract. For a more complete discussion of the legal issues surrounding production contracts, please visit the Production Contracts Reading Room.
