1 All AFOs with numbers of animals above the size thresholds set out for Large CAFOs are defined as
CAFOs under the NPDES federal regulations.

2 NPDES CAFO regulations require CAFOs that discharge to have NPDES permit coverage (40 CFR
122.23(d)(1)). As a consequence, the portion of CAFOs that need NPDES coverage can vary from State
to State.
