Clean Water Act's National Pollutant Discharge Elimination System (NPDES) program for concentrated animal feeding operations (CAFOs)
Animal Feeding Operations (AFOs) are agricultural operations where animals are kept and raised in confined situations. AFOs generally congregate animals, feed, manure, dead animals, and production operations on a small land area. Feed is brought to the animals rather than the animals grazing or otherwise seeking feed in pastures. Animal waste and wastewater can enter water bodies from spills or breaks of waste storage structures (due to accidents or excessive rain), and non-agricultural application of manure to crop land.
- 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, and
- Crops, vegetation, forage growth, or post-harvest residues are not sustained in the normal growing season over any portion of the lot or facility.
AFOs that meet the regulatory definition of a concentrated animal feeding operation (CAFO) may be regulated under the NPDES permitting program. The NPDES program regulates the discharge of pollutants from point sources to waters of the United States. CAFOs are point sources, as defined by the CWA [Section 502(14)]. To be considered a CAFO, a facility must first be defined as an AFO.

Animal Agriculture Education Project
As part of EPA’s efforts to protect water quality through voluntary collaborations with the animal agriculture sector, EPA is announcing the launch of the Animal Agriculture Education Project. This will include a series of educational modules to increase understanding and knowledge among state and federal government agencies and the agricultural industry about water quality protection and animal feeding operations. The first module, Animal Agriculture, Manure Management, and Water Quality, will cover the following topics:
- Animal Agriculture Trends
- Manure Collection and Storage
- Land Application of Manure Nutrients
- Water Quality and Manure
- Clean Water Act Requirements
- Planning for Stewardship
The Animal Agriculture Education Project includes multimedia features such as videos and virtual tours of farms and discusses topics including advances in technologies and production systems, measures to protect water quality, and issues involved in on-farm decision-making about manure management.

Air Quality Conservation Practices
- Agricultural Air Quality Conservation Measures Reference Guide for Poultry and Livestock Production Systems - This guide describes different conservation measures for poultry and livestock operations that have been successfully demonstrated to reduce emissions of various air pollutants on farms. In addition, it offers general comments on the applicability of the measures to different types of farms and ranges of potential emission reductions.
CERCLA and EPCRA Reporting Requirements
- CERCLA and EPCRA Reporting Requirements for Air Releases of Hazardous Substances from Animal Waste at Farms - On November 22, 2017, the DC Circuit Court of Appeals granted EPA’s motion to further stay the mandate until January 22, 2018. Farms with continuous releases do not have to submit their initial continuous release notification until the DC Circuit Court of Appeals issues its order, or mandate, enforcing the Court’s opinion of April 11, 2017. No reporting is necessary until the mandate is issued.

- Nutrient Pollution and Agriculture - Animal manure, excess fertilizer applied to crops and fields, and soil erosion make agriculture one of the largest sources of nitrogen and phosphorus pollution in the country.
- Estimated Animal Agriculture Nitrogen and Phosphorus from Manure - Animal agriculture manure is a primary source of nitrogen and phosphorus to surface and groundwater. Manure runoff from cropland and pastures or discharging animal feeding operations and concentrated animal feeding operations (CAFOs) often reaches surface and groundwater systems through surface runoff or infiltration.
