This MPCA Smart Salting Certification Training is an opportunity to learn more efficient winter maintenance best practices (BMPs) while taking a comprehensive look at the many aspects for managing snow & ice on parking lots and sidewalks. The training will also cover the new chloride requirements in the recently released MS4 permit, as well as resources available to help you reduce your salt use.

The training will be held in-person.

Who should attend?

• Hands-on public or private winter maintenance staff
• Those who hire or supervise winter maintenance staff
• Private contractors
• Those who may influence others or are interested in making a difference at work

What you’ll learn:

• Environmental impacts of chloride
• Equipment calibration
• Using weather condition info more efficiently
• Application rates
• Plowing and physical removal
• BMPs for storing materials
• De-icing and anti-icing
• Regulatory issues and managing liability
• Customer and staff educational resources
• Success stories

Earn the MPCA Smart Salting for Parking Lots & Sidewalks certification by taking the optional online test at the end of training and be listed on the MPCA Smart Salting webpage. Certificates are sent to Minnesota participants only and are valid for 5 years.

MPCA permittees are allowed registration preference. If the training exceeds capacity, those that are not permittees will be put on a waitlist and notified accordingly.

This training is hosted by Dakota County and the MPCA Chloride Reduction Program. with Clean Water Fund and the Environment & Natural Resources Trust Fund.

Learn best practices to reduce salt use during high-speed and low-speed snowplow operation, while maintaining safety. Participants earn a five-year Level 1 (individual) certification by completing the test at the end of class.

This spring and summer, the Vermillion River Watershed Joint Powers Organization (VRWJPO) is leading an Alimagnet Lake alum (aluminum sulfate) treatment feasibility study. City of Burnsville and City of Apple Valley natural resources staff are also participating in the process. VRWJPO has hired a consultant, Barr Engineering, to conduct field work, analyze data and help put together the final feasibility report. This report is expected to be completed in July. We are hosting a public meeting on July 20, 2023 where the findings of the report will be presented.

What is an alum treatment?

An alum treatment is a common water quality improvement practice in shallow lakes that have excessive phosphorus and poor water clarity as a result of algae growth. Often times phosphorus is released into the water column from lake bottom sediments during the summer months. When alum is added to the water, it attaches to phosphorus and falls to the bottom of the lake, preventing it from feeding algae and improving water clarity. Increased clarity following alum treatments can also lead to increased aquatic plant growth, which help to keep phosphorus levels in check.

One of the first steps in planning for a potential alum treatment is to conduct a feasibility study, which will determine whether Alimagnet Lake is a good candidate for the treatment, and if it is, how to most effectively apply alum in the lake, and the estimated costs. The study will also look at alternative solutions to improve water quality, other than an alum treatment.

At the public meeting, there will be a short presentation to present the findings of the study and then time for attendees to ask questions or provide feedback on the findings. If alum treatment is determined to be a feasible option for Alimagnet Lake, VRWJPO would anticipate applying for a grant in late summer of 2023 to obtain funding to complete the work. No treatment would occur prior to 2024.
