Industrial storm water permit forms
Use the forms below to apply for general industrial storm water discharge permits and meet compliance requirements.
Industrial forms and reports (such as SWPPPs, inspection, and sampling documents) can now be submitted through the Water ePermitting System. Since October 2020, applicants submitting a NOI for coverage under an industrial storm water permit must use the online e-permitting system. *See the Step-by-step help document at ePermit User Support Tools.
When to submit a Notice of Intent
- New industrial facilities must apply for permit coverage with a Notice of Intent (NOI) at least 14 working days prior to initiating industrial operations. Coverage under an industrial storm water discharge permit must be conferred before the facility is in operation.
- Facilities are required to develop and submit a Storm Water Pollution Prevention Plan (SWPPP) summary to the DNR prior to initiating construction and may also need to submit a Notice of Intent if there will be clearing, grading, excavating, or stockpiling of fill material resulting in the disturbance of one or more acre of land at the site during construction.
How to apply
Beginning October 1, 2020, applicants submitting a NOI for coverage under an industrial storm water permit must use the online e-permitting system. The e-permitting system is available for use at water permit applications. The e-permitting system does not require any special software and is completely web-based and available using any internet browser.
If the facility does not have materials exposed to storm water, applicants may apply for No Exposure Certification. If the facility has been sold, permit coverage can be transferred to the new operator.
Notice: Some web browsers do not open PDF files on their own. If you experience trouble opening or filling out a PDF form, visit the DNR PDF help for instructions on how to successfully open PDF files.

There is no application fee to apply for permit coverage. However, an annual fee is charged to all industrial storm water permittees. Invoices for the annual fees are mailed to all facilities in May/June of each year. Instructions on how to pay the fee, where to mail the invoice and payment, and the due date are all indicated on the invoice.
The amount of the annual fee depends on whether the facility is a general permit or an individual permit holder. At this time, the DNR is issuing only general permits.
Fees for the different general permits are $260 per year for Tier I permittees and $130 per year for Tier 2 permittees.

Industry permit search
Search the industrial storm water database for permitted facilities. If the facility’s SIC code is one of those that is required, by category, to have a permit, it should be on the list of permitted industrial facilities. If the facility has been granted a no exposure exclusion, it should be on the list of facilities with that status.
If the facility does not have permit coverage or no exposure exclusion, a Notice of Intent or a No Exposure Certification Request must be completed via the online e-Permitting system, beginning September 2020.
The DNR Water Permits web site and the US EPA web site [exit DNR] may have additional information for industrial facilities.
