Detailed explanation-1: -The US EPA defines CAFOs as livestock operations where the animals are confined for at least 45 days in a 12-month period and have no grass or other vegetation present in the confinement during the normal growing season.
Detailed explanation-2: -Iowa has more CAFOs than any other state-nearly 4, 000-but only 4% have NPDES permits. The EPA standard is “both the floor and the ceiling” in Iowa, Heinzen said.
