Construction site storm water permits

Important information concerning the DNR’s WPDES general permits

The following WPDES general permit has been reissued, effective October 1, 2016:

The DNR’s construction site permit requires landowners to install practices to help decrease the amount of sediment that pollutes Wisconsin’s waterways from construction projects. Land disturbance during a construction project exposes bare soil which can erode during storm events. Practices help decrease the amount of sediment that runs off during a storm event.

Erosion control plans contain specific practices to reduce erosion, divert storm water from disturbed or exposed construction site areas, and trap and control the transport of sediment and other pollutants. Construction site permits contain requirements for controlling erosion and storm water during construction as well as managing storm water runoff after construction is completed.
