Storm Water Management

The ultimate goal of the WPDES Storm Water Program is to prevent the transportation of pollutants to Wisconsin's water resources via stormwater runoff.

Runoff into storm drain According to EPA’s National Water Quality Inventory: 2000 Report, prepared under Section 305(b) of the Clean Water Act, urban storm water runoff and discharges from storm sewers are a primary cause of impaired water quality in the United States. These sources contribute to 13 percent of impaired rivers and streams, 18 percent of impaired lakes, 55 percent of impaired ocean shorelines, and 32 percent of impaired estuaries. Storm water runoff from construction activities can have a significant impact on water quality. In addition to sediment, as storm water flows over a construction site, it can pick up other pollutants like debris, pesticides, petroleum products, chemicals, solvents, asphalts and acids which also contribute to water quality problems.

To meet the requirements of the federal Clean Water Act, the Wisconsin DNR developed the Wisconsin Pollutant Discharge Elimination System (WPDES) Storm Water Discharge Permit Program which is regulated under the authority of ch. NR 216, Wis. Adm. Code [exit DNR]. As part of the EPA National Pollutant Discharge Elimination System (NPDES), the WPDES Storm Water Program regulates discharge of storm water in Wisconsin from construction sites, industrial facilities, and selected municipalities. Beyond regulatory storm water management, the Department also supports a wide variety of voluntary storm water management activities. These include projects funded through the Urban Nonpoint Source and Storm Water and Targeted Runoff Management Runoff Grant Programs.

The University of Wisconsin Extension [exit DNR] and EPA Office of Wetlands, Oceans, and Watersheds [exit DNR] have additional information available about storm water management from the scale of a residential rain garden through construction site erosion control plans for multi-acre construction sites.

EPA Links to Help Storm Water Program Managers

EPA's resource list for storm water program [PDF 95 KB] - Resources to help stormwater program managers start developing or improve their stormwater programs. This list is divided into six sections: general stormwater information, public education and outreach, illicit discharge detection and elimination, construction site runoff control, post-construction site runoff control, and pollution prevention/good housekeeping.
