 October 31, 2026 is the application deadline to apply for the Multi-sector General Permit (MSGP) and No Exposure Certification application service for the 2025-2030 permit cycle in e-Services.
Application guidance can be found on the Industrial Stormwater webpage.
New process for this application
To submit an application for the MSGP or the no exposure certification, you must first have Industrial Stormwater (ISW) signatory access for the facility. If you have previously submitted ISW monitoring results or annual reports through e-Services, you should already be granted this access and can proceed to reapply for the MSGP or no exposure certification. If you currently do not have ISW signatory access for your facility, you must complete the following steps before you can reapply for either the MSGP or no exposure certification.
For facilities previously issued a MSGP or no exposure certification
1. Ensure you have your facility added to your e-Services account, and request ISW signatory access if you do not currently have it.
2. Download and complete the industrial stormwater electronic signature agreement/signatory registration form. Add your information and the information for the facility’s responsible official/owner. Make sure to include the facility’s MSGP permit number or no exposure certification identification number; these numbers begin with MNR053 or MNRNE.
3. Submit the form to the email address on the final page of the form. After you receive notification the signatory authorization has been approved, complete and submit the MSGP permit or no exposure certification application through e-Services.
For facilities without a previous MSGP or no exposure certification
Please contact the Industrial Stormwater compliance and enforcement staff assigned to the county you are located in for further instruction.
Pro Tip: If there are additional personnel changes at your facility after you are issued the MSGP or no exposure certification, modify your permit/certification by submitting an administrative modification request through e-Services to keep your contact information updated with us. There is no fee for an administrative modification.
 If you are reapplying for coverage with the Industrial Stormwater Program and are unsure of your facility permit ID, no exposure certification ID, or the facility ID, you can find this information using the MPCA's What's In My Neighborhood (WIMN) web application map search tool.
1. Enter your facility name or address into the WIMN map search.
2. Click on the icon at your facility. You may need to zoom the map out to see it.
3. The facility ID and MSGP permit or no exposure certification number will appear in the pop-up window. ISW permit IDs start with MNR053 and No Exposure certification IDs start with MNRNE.
Pro Tip: If searching by address, enter the street number and name. You don't need to enter the city, state, or zip code.
There is no benchmark monitoring waiver available for previously meeting the permit benchmark values under the 2020-2025 MSGP. Waiver requests that include a justification of previously meeting benchmark values will be denied.
