Are you a Municipal Separate Storm Sewer System (MS4) permittee?

The new MS4 General Permit is planned to be issued on Monday, November 16, 2020. Existing MS4 permittees will have 150 days (April 15, 2021) to complete and submit the permit application forms to the Minnesota Pollution Control Agency (MPCA).

There will be an opportunity to join other MS4 communities and MPCA staff to learn about the new MS4 requirements for chloride and find out what other MS4 communities have implemented to improve their winter maintenance operations on Monday, October 5th, from 8:30 am to 12 pm. This discussion will be online and hosted by the MPCA. It is a great chance to get a step ahead on planning ways to meet upcoming permit requirements.

The next MS4 General Permit will require specific chloride reduction activities for permittees such as community education, annual training for your winter maintenance staff, proper deicing salt storage practices, and other requirements. Some permittees must also conduct an annual winter maintenance operations assessment to assist in identifying deicing salt reduction opportunities on permittee owned/operated surfaces. The MPCA Smart Salting Assessment tool is one way to complete the assessment requirement.

Register today for this free, online live-stream to openly and informally discuss how we can all reduce the permanent effects of chloride pollution in Minnesota and protect our water resources. Contact Brooke Asleson brooke.asleson@state.mn.us or Cole Landgraf cole.landgraf@state.mn.us with questions and to register.
