Stormwater Permitting

South Dakota's General Permit for Stormwater Discharges Associated with Construction Activities was public noticed on February 9, 2018. The public notice and supplemental documents can be found on DENR's One-Stop Public Notice page. DENR formally published the permit throughout the state for the official 30-day public comment period in the following newspapers:

                       American News (Aberdeen, SD)        Brookings Register (Brookings, SD)        Plainsman (Huron, SD)

                       Daily Leader (Madison, SD)              The Daily Republic (Mitchell, SD)            Capital Journal (Pierre, SD)

                       Rapid City Journal (Rapid City, SD)   Argus Leader (Sioux Falls, SD)               Black Hills Pioneer (Spearfish, SD)

                       Public Opinion (Watertown, SD)        Daily Press & Dakotan (Yankton, SD)

  This current permit expired January 31, 2015, and has since been administratively extended.

  The stormwater staff hosted a meeting over the Dakota Digital Network (DDN) to discuss the proposed changes in the draft permit and funding for the permitting program. The recording of this DDN presentation and a pdf of the presentation can be found here:

South Dakota's General Permit for Stormwater Discharges Associated with Industrial Activities expired September 30, 2017, and has been administratively extended. DENR has sent a renewal notice to each permitted facility with instructions for submitting a Notice of Intent for Reauthorization and a Certification of Applicant form. If you did not receive one but have an industrial permit, please contact the stormwater staff by email or by calling 1-800-SDSTORM (1-800-737-8676) to get a form for your facility. The new general permit will not be reissued before September 30, 2017; however, if we receive 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 the new general permit has been issued. DENR is currently processing all of the reauthorizations and preparing to send out approval letters to those who reauthorized.

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.

You may obtain hard copies of the application and termination form by contacting the stormwater staff at 1-800-SD-STORM.  PDF versions of the application and termination forms are also available.

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.
