Construction Site Erosion Control and Storm Water Management
Due to these high erosion rates (lack of vegetation) and high delivery rates (efficient ditches and storm sewers), construction sites are by far the largest source of sediment that pollutes the water resources of Wisconsin.* WPDES Construction Site Erosion Control and Storm Water Discharge Permits are designed to help decrease the amount of sediment that pollutes Wisconsin's waterways each year. Landowners of most construction projects where one or more acres of land will be disturbed must obtain a WPDES Construction Site Erosion Control and Storm Water Discharge Permit. Construction sites that are directed and supervised by the Wisconsin Department of Transportation are regulated by that department. WI Department of Transportation [exit DNR]
All other construction sites where one or more acres of land will be disturbed need to obtain a WPDES Construction Site Erosion Control and Storm Water Discharge Permit.
Before conferring permit coverage, the Department will review the project location to determine if storm water discharge from the project will impact wetlands, registered historical / archaeological sites, or endangered / threatened resources. Landowners should contact the appropriate DNR regional storm water staff as early as possible during project development to determine if the project will come in contact with any of these three resources. To obtain a Construction Site Erosion Control and Storm Water Discharge PermitThe landowner must:
