Comparison: State vs. Federal

Rules. Oregon is authorized by the U.S. Environmental Protection Agency (EPA) to administer the federal National Pollutant Discharge Elimination System (NPDES) permit program for wastewater discharges, including permitting authority for concentrated animal feeding operations (CAFOs). The state uses both the federal definition of CAFOs and includes additional facilities and operations in its definition. See the national section AG WASTE for more information on the federal permitting program.
