Comparison: State vs. Federal

Rules. Wisconsin generally follows the federal effluent limitations guidelines for discharges to state water; however, Wisconsin also relies heavily on water-quality-based effluent limitations, and the state's requirements are generally complex compared with the federal rules. Wisconsin has also imposed a set of phosphorus water quality standards for lakes, reservoirs, and the Great Lakes, and procedures for determining and incorporating phosphorus water-quality-based effluent limitations into Wisconsin Pollutant Discharge Elimination System (WPDES) permits.
