MPCA direct assistance

The MPCA administers several programs that can assist organizations looking to address salt use and chloride pollution:

  • Minnesota GreenCorps – Places AmeriCorps members with host organizations around the state to assist with a variety of environmental efforts, including reducing salt use and minimizing chloride pollution
  • GreenStep Cities – A free, voluntary challenge, assistance, and recognition program to help cities achieve their sustainability and quality-of-life goals. Reducing salt use is one of the recommended best practices.
  • Small Business Environmental Assistance – MPCA's program for helping small businesses meet regulatory obligations and reduce their impact on the environment.
  • Clean Water Partnership loans - MPCA offers zero-interest loans to local government and tribal communities to implement practices that reduce non-point sources of chloride pollution.

Model snow and ice policies

The model snow and ice policy is designed to help county and city governments adopt winter maintenance policies that include protecting the environment among their goals.

Sample policies

Model winter maintenance contract

The city of Edina developed a model contract for snow and ice management that embraces best practices to minimize environmental impacts from salt and other chemicals. Property owners can adapt the model contract to suit their needs and to ensure their contractors are protecting Minnesota waters from chloride pollution.

Example regulatory rules, policies, and ordinances

Several organizations have implemented various rules, polices and ordinances to reduce salt pollution in their community.
