Attention Municipal Separate Storm Sewer System (MS4) permittees! On Monday, Oct. 5, from 8:30 a.m. – 12 p.m., the Minnesota Pollution Control Agency will be hosting an online chloride discussion. This is an opportunity to join other MS4 communities and MPCA staff to learn about the new MS4 permit requirements for chloride and find out what other MS4 communities have implemented to improve their winter maintenance operations.

This 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 de-icing 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.

Several MS4s will share their experiences on how they have proactively benefited from chloride reduction actions ahead of the new requirements, and discuss the changes they have made that have improved their winter snow and ice maintenance operations, as well as lowering their environmental impact.

This is a free, online live-stream gathering to openly and informally discuss how we all can reduce the permanent effects of chloride pollution in Minnesota and protect our water resources. Register today! Contact Brooke Asleson or Cole Landgraf with questions and to register.
