• Rules. Wisconsin is fully authorized by the U.S. Environmental Protection Agency (EPA) to administer the National Pollutant Discharge Elimination System (NPDES) permit program in Wisconsin, including the pretreatment program. Wisconsin Pollution Discharge Elimination System (WPDES) permits are the state's equivalent of the federal NPDES permits. For more specific information on WPDES permits, see the state section NPDES PERMIT.
