Storm Water Permit for Construction Activities
If you are planning a construction project, you may need a permit for storm water discharges from your construction site. Construction activities include:
- Clearing, grading, or excavation;
- Road building;
- Construction of residential, commercial, and industrial buildings;
- Installing pipelines, cable lines, and phone lines; and
- Demolition activities.
Any construction activity disturbing one or more acres must have coverage under a storm water permit. Any sites that are part of a larger plan or sale may also need a permit, if the total plan meets the acreage requirement.
In 2002, DENR issued a General Permit for Storm Water Discharges Associated with Construction Activity. A general permit is a permit for a specific activity issued throughout the state. This General Permit has expired and the department issued a new permit December 31, 2009. The new permit became effective February 1, 2010. Follow this link for more information.
The permit has simple and uniform terms to prevent any storm water from becoming polluted prior to leaving your construction site. You should make sure to read and understand the conditions of the permit. A copy of the Storm Water Construction Permit is available in adobe acrobat format. You may also obtain a hard copy by contacting DENR.

To obtain coverage under storm water permit, fill out the short application form, called the Notice of Intent. You must submit the form to DENR at the following address at least 15 days prior to starting your project:
Department of Environment and Natural Resources
Surface Water Quality Program
Joe Foss Building
523 East Capitol
Pierre, SD 57501-3181
If your project is already in progress, you should submit a Notice of Intent immediately. If the project is within city limits, DENR recommends you contact the city to determine if there are any 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 before construction begins. The requirements of the pollution prevention plan can be found here.
