Animal Feeding Operations (AFOs) - Animal Agriculture Industry Partnerships

EPA and the animal agriculture industry are collaborating to enhance water quality protection through voluntary partnerships. There are four parts to this program:

Open Dialogue

EPA established an Animal Agriculture Discussion Group (AADG) to develop a shared understanding of how to implement the Clean Water Act. AADG keeps communication open and improves two-way understandings of viewpoints. AADG is an informal and iterative group of animal agriculture stakeholders including representatives from the U.S. Department of Agriculture (USDA), all sectors of the animal feeding industry and their associations, academia, and states. The group convenes via conference calls and face-to-face meetings twice per year.


EPA and industry collaborate to conduct joint projects for water quality protection. Noteworthy partnership projects include:

  • Beneficial Uses of Manure and Environmental Protection - A two-page outreach piece developed with agriculture industry organizations.
  • US Poultry & Egg Association's YouTube webpage Exit- Video series produced by the U.S. Poultry & Egg Association for poultry producers on environmental management, as part of EPA’s education, outreach, and training efforts, released in January 2016.
  • Continuing EPA participation in individual sector environmental stewardship awards including U.S. Poultry and Egg’s Family Farm Awards, and the Innovation Center for U.S. Dairy’s Sustainability Awards.

Practices and Technologies

Through the Nutrient Recycling Challenge, EPA and twenty partners are harnessing the power of competition to encourage the development and adoption of nutrient recovery technologies. These technologies can extract or transform the nutrients in manure and sequester them into valuable products that could be used onsite, transferred, or sold to where they are needed. For more information see: Nutrient Recycling Challenge website.

Better Information and Training

EPA, USDA Natural Resources Conservation Services and AADG are developing an educational program to facilitate two-way understanding of livestock and poultry feeding operations and water quality protection measures.

Module I, Animal Agriculture, Manure Management and Water Quality, covers:

  • Trends in Animal Agriculture,
  • Manure Collection and Storage,
  • Land Application of Manure Nutrients,
  • Water Quality Issues Associated with Manure,
  • Clean Water Act Requirements, and
  • Planning for Stewardship.

The content includes dynamic multimedia features such as videos and virtual tours of farms.

Module II covers agricultural conservation practices and will be available in late 2017.
