Reissuing the municipal stormwater general permit

The municipal stormwater general permit (also called the MS4 general permit) must be reissued every five years. The current permit has expired and the MPCA has drafted a proposed new permit. The agency is asking for public comments on the draft and has compiled some resources to assist interested parties.

The Minnesota Stormwater Manual also has multiple guidance documents related to the requirements in the proposed permit.

Submit comments

The MPCA is seeking input on the proposed permit, which is open for public comment until 4:30 p.m. on Saturday, January 11, 2020. Submit comments via the survey form, or mail or email comments to Cole Landgraf, MPCA, 520 Lafayette Road N, St. Paul, MN 55155.

Informational webinar

The MPCA will hold an interactive webinar via WebEx on Wednesday, December 11, from 9:00 a.m. to 12:00 p.m. (Central time) to share information about the proposed permit. The agency will provide a brief presentation starting at 9:00 a.m., but the rest of the webinar will be devoted to answering questions. If you know others interested participants, we encourage you to view it together in one room. The webinar will be recorded and made available after it's over.

Register for the webinar on WebEx before 8:00 a.m. on Wednesday, December 11.

Asking questions

You may ask questions through a chat box during the meeting. However, the MPCA encourages you to send questions prior to the meeting to ensure we cover the issues you care about. Send questions to by the end of the day, December 9, 2019. 

NOTE: Questions or comments submitted during the webinar do not constitute official comments. See instructions above for submitting comments.
