Stormwater Permitting

Effective July 1, 2018, annual stormwater fees for the General Permit for Stormwater Discharges Associated with Construction Activities are effective and due when the Notice of Intent is submitted. A permit will not be issued until the first year's annual fee has been paid by check or credit card. Visit the Stormwater Permit for Construction Activities webpage to view the annual fee amounts.

Effective April 1, 2018, South Dakota's General Permit for Stormwater Discharges Associated with Construction Activities was reissued. Existing Stormwater Pollution Prevention Plans (SWPPPs) need to be updated by October 1, 2018, as required by Section 5.1.1 of the new permit.

Industrial Permit Holders: South Dakota's General Permit for Stormwater Discharges Associated with Industrial Activities expired September 30, 2017, and has been administratively extended. If we received your reauthorization form, your permit coverage continues in full force and effect until the new general permit is issued. DENR will notify permitted facilities once a draft general permit has been prepared for public notice.


Stormwater runoff occurs when precipitation from rain or snowmelt flows over the ground. Impervious surfaces like driveways, sidewalks, and streets prevent stormwater runoff from naturally soaking into the ground.

Stormwater can pick up debris, chemicals, dirt, and other pollutants and flow into a storm sewer system or directly to a lake, stream, river, wetland, or coastal water. This stormwater is often discharged untreated into the waterbodies we use for swimming, fishing and drinking water. For example, erosion at a construction site can cause sediment to enter surface waters, as can be seen from this picture.

In 1972, Congress passed the Federal Water Pollution Control Act, commonly referred to as the Clean Water Act. The stated goal of the act was to restore and maintain the chemical, physical, and biological integrity of the Nation's waters. To achieve this goal, the Clean Water Act states the discharge of any pollutant by any person shall be unlawful except in compliance with other provisions of the statute.

The Clean Water Act required a program for addressing the pollution caused by stormwater discharges. South Dakota has developed general permits to provide a simple process for getting a stormwater permit. The links below provide information about each of these permits:

Permittees are required to develop a pollution prevention plan. This plan details the best management practices a facility will use to ensure that the stormwater from their site will not impact our surface waters.

EPA has additional information available about the National Stormwater Program (Please note: this link will take you out of the state of South Dakota web site). Please contact the stormwater staff at 1-800-SDSTORM (1-800-737-8676) for information about South Dakota's Stormwater Program.

South Dakota has also developed some multi-media general storm water permits. These permits combine the stormwater requirements with the permitting requirements under the Clean Air Act. Currently, general permits have been developed for Rock Crushers, Asphalt Plants, and Concrete Plants. Additional Information about these permits, as well as information about South Dakota's air permitting program is available on the internet at the Air Quality Program web site.
