Storm Water Permit for Industrial Activities


If you operate a business or industry, you may need a permit for storm water discharges from your site. The need for an industrial permit is based on the types of activities that you do at your site.


How Do I Get Coverage Under the General Storm Water Permit for Industrial Activities?

In South Dakota, DENR has a General Permit for Storm Water Discharges Associated with Industrial Activity. A general permit is a permit for a specific activity issued throughout the state. The permit covers anyone meeting the conditions of the general permit. There is no fee for this permit. The permit has simple and uniform terms to prevent any storm water from becoming polluted prior to leaving your industrial site.


If you need a storm water permit, fill out a short application form, called a Notice of Intent which includes a Certification of Applicant form.






You must submit the form to DENR at the following address at least 15 days before a discharge occurs:


Department of Environment and Natural Resources
Surface Water Quality Program
Joe Foss Building
523 East Capitol
Pierre, SD 57501-3181


If you are already operating at your site, you should submit a Notice of Intent immediately. If you are located within city limits, we recommend you contact the city to determine if the city has additional requirements.


Pollution Prevention Plans


As part of the storm water permit, you must develop a pollution prevention plan. You must have your plan in place once construction begins.


The pollution prevention plan must include:


  • A description of the project;
  • A description of how you will control run-off and reduce pollutants;
  • A site map showing the direction of any drainage, and the location of any storm water controls;
  • The name of any bodies of water near the site; and
  • An inspection and maintenance schedule for storm water controls at the site.


You are responsible for implementing the pollution prevention plan. You must update the plan when changes occur, and list any person(s) who will carry out a part of the plan. You must keep a copy of your plan on-site. You are not required to send a copy of the plan to DENR, unless DENR specifically requests it.


The following is a draft SWPPP. You may edit it and use it as you see fit.


Waiver for the Storm Water Industrial Permit


DENR is now allowing an exclusion from the storm water permitting requirements for facilities whose industrial materials or activities are not exposed to precipitation or runoff. If there is no exposure to storm water at an industrial facility, then a storm water permit is not required.

Industrial facilities wishing to be conditionally excluded from permitting requirements must submit a certification form to the department. By submitting this form, the facility is certifying there is a condition of no exposure to storm water at the site.



DENR has additional information available to help you:


  • The federal storm water permitting rules adopted by the state.
  • South Dakota’s general storm water permit for industrial activities.
  • Guidance manuals to help you develop your plan.


You may obtain more information about requirements for storm water discharges associated with construction activities or requirements for storm water discharges associated with other industrial activities by calling 1-605-773-3351.


Please Note: The General Storm Water Permit For Industrial Activities lists the expiration date as November 15, 2008.  However, this permit has been administratively extended until a renewal permit is issued.
