Statewide Chloride Management Plan

Minnesota has a growing salty water problem that threatens its freshwater fish and other aquatic species.

The MPCA, in collaboration with several partners, has drafted the State Chloride Management Plan to help local government units, winter maintenance professionals, decision-makers, and others take action to protect Minnesota’s water resources from chloride pollution.

Uses for the plan

In addition to protecting water resources, reducing salt use will also lead to long-term cost savings in salt purchases and prevent harm to vegetation and corrosion of infrastructure and vehicles.

You may use the plan to:

  • Better understand the sources of chloride. In Minnesota, the three main sources are road salt runoff; water softener brine that passes through in wastewater; and fertilizer, manure and dust suppressants.
  • See the trends in chloride pollution statewide.
  • Determine goals for local reductions in salt use.
  • Detect and prioritize critical areas for reducing salt use.
  • Research strategies to reach local goals.
  • Implement and measure those goals.
  • Learn what tools and resources the MPCA has for reducing salt use.
