Construction site storm water permits

Important notice:

Construction site soil loss and sediment discharge calculation

Note: Required January 1, 2016

The Soil Loss and Sediment Discharge Calculation Tool was developed to provide direction and assistance to Department staff, developers, municipalities and consultants. The guidance document establishes a procedure to document compliance with the 5 tons per acre per year sediment performance standard for construction sites pursuant to s. NR 151.11, Wis. Adm. Code.

Effective January 1, 2016, the results of soil loss and sediment discharge calculations must be documented in a summary report and included with the construction site storm water permit application (Notice of Intent).

On October 22, 2015, the DNR held an informational webinar to provide an overview of the guidance, explain the calculation tool, and provide documentation requirements in the application for permit coverage. The webinar recording is split into 5 parts:

The construction site storm water e-permitting system

Note: Required September 1, 2015

The Wisconsin DNR is implemented an online permit application system for the construction site storm water permit program. Using the e-permitting system to apply for the construction site storm water permit has been required as of September, 14, 2015, after which paper applications will no longer be accepted.

How to get started
The e-permitting system does not require any special software and is completely web-based and available using any internet browser. To begin, go to water permit applications.

On July 29, 2015, the DNR held an informational webinar to provide an overview of the e-permitting system and explain the application steps and process. The webinar was recorded for later viewing.

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.
