MS4 General Permit reissuance process

The Minnesota Pollution Control Agency (MPCA) is developing the next Municipal Separate Storm Sewer System (MS4) General Permit. As part of the permit reissuance process, three separate opportunities for stakeholders to provide input are planned. For details about those opportunities and planned changes for the next permit, please visit the MS4 General Permit website.

At this time, all interested and affected parties are encouraged to provide written input on the current 2020 MS4 General Permit. This may include suggested changes or areas of the permit where improvements could be made, including where additional details or guidance are desired. The MPCA will review comments and may incorporate suggested changes into the new draft permit.

To submit a comment, email ms4permit.pca@state.mn.us with the subject line: 2020 MS4 General Permit feedback. Please include your name, organization (if applicable), and your comment. In your comment, please be as specific as possible, including reference to permit item number(s) and suggestions on how the permit could be improved.

The MPCA is accepting written feedback on the 2020 permit until May 31, 2025.
