Stormwater Permits

Stormwater runoff and snow melt can pick up chemicals, bacteria, sediment, and debris from urban areas, construction sites, and industrial facilities. Runoff that enters a storm sewer or ditch does not go to a lagoon or treatment plant. Instead, runoff flows directly to rivers, lakes, and streams without any treatment.

Stormwater permits provide a level of treatment through planning and management that minimizes pollution in runoff from urban areas, construction sites, and industrial facilities.

There are no fees for stormwater permits. For more information please email


Construction Permits

Construction Permits: The construction general permit applies to construction projects that disturb one or more acres including smaller projects within or part of a large development.

1. Develop Stormwater Pollution Prevention Plan (SWPPP) to minimize pollution from soil erosion and other sources

2a. Submit an electronic Notice of Intent and mail an original signed copy no later than seven days before construction starts
2b. Submit a Notice of Intent through the Electronic Reporting System (ERIS)

3. Implement the SWPPP to minimize pollution from soil erosion and other sources like fuel, oil, and waste

4. Monitor the site and complete inspections

5. Submit a notice of termination once final stabilization has been met

A project is automatically covered under the permit seven days after the department receives the notice of intent.

Coverage under the permit is required for oil and gas projects if runoff from the project can carry eroded material to a water of the state. Coverage is not required for oil and gas projects if runoff will not carry eroded material to a water of the state.

Industrial Permits

Industrial permits are required if a facility falls under a specific primary Standard Industrial Classification (SIC) Code. Examples of industrial activity under these codes include, but are not limited to Asphalt/Concrete plants, Landfills, Manufacturing, and Transportation.   Find your facility's SIC code on the OSHA Website. See the EPA Website to find out if your facility requires a permit.

Mining, Extraction & Paving Material Permits

The permit issued for mining or extraction activities is a "General" permit. A general permit written to address all mining or extraction activities and the same permit is issued to all applicants.

Municipal Seperate Storm Sewer Systems (MS4)

EPA's Phase II Final Rule published in December, 1999, included permit requirements for designated small municipalities and certain facilities that maintain control of a separate storm sewer system.  The small Municipal Separate Storm Sewer System (MS4) Permit covers stormwater discharges from these systems.
