Animal Feeding Operations


Overview

Animal feeding operations (AFOs) are agricultural entities that raise animals in confined areas. More specifically, AFOs are defined in the regulations implementing the Clean Water Act (CWA) as facilities, except aquatic animal production facilities, that confine and feed animals for 45 or more days per year and do not have sustained vegetation during the growing season over any portion of the facility. This overview focuses on environmental regulation and common law actions as they pertain to animal feeding operations. Read the full overview
