Concentrated Animal Feeding Operations

Concentrated Animal Feeding Operations are agricultural facilities that house and feed a large number of animals in a confined space for a limited period of time. As of April 2003, the federal government requires all CAFOs to obtain a National Pollutant Discharge Elimination System permit and to develop a plan for proper management of animal wastes on the site. They must also report those practices to the U.S Environmental Protection Agency each year.

There are approximately 450 CAFOs operating in Missouri. These operations generate a large amount of manure and have the potential to seriously impact our water resources. The state’s rules and regulations are designed to minimize the risks CAFOs pose to water quality and public safety. Water quality is protected through the department's permit process.
