CAFO and CAFO WPDES permit statistics

Wisconsin is home to an increasing number of Concentrated Animal Feeding Operations (CAFOs). The Department of Natural Resources is pleased to offer you easy access to statistics and geographical information about Wisconsin's CAFOs and the applicable Wisconsin Pollutant Discharge Elimination System (WPDES) permits.

Wisconsin CAFO WPDES permits by animal type over time

Note: Beginning July 1, 2002, a single permit issued to Jennie–O Turkey Store (JTS) covered 55 of their operations. Previously, there were 17 separate permits for each of the operations with 1,000 animal units or higher. This reduction in the number of separate permits issued to JTS reduced the number of total permits issued in Wisconsin.
