Certification and tools for organizations

Smart Salting tool

The Minnesota Pollution Control Agency has recently updated and redesigned its Smart Salting tool to help communities and organizations across the state evaluate sources of chloride impacting local water resources. The Smart Salting tool also provides support and guidance on how to address those sources.

The Smart Salting tool is now a comprehensive chloride reduction tool and includes these key features and more:

  • mapping feature to select specific geographic area for customized evaluation of chloride sources
  • detailed information for each source of chloride
  • guidance for how to collect additional information and data
  • option to modify estimated chloride contributions with local data 

The Smart Salting tool can help organizations and communities address chloride pollution by supporting a customized approach:

  • Develop a chloride reduction action plan for your community or organization.
  • Assist with MPCA permit reporting requirements related to chloride.
  • Evaluate your winter maintenance or dust suppressant best management practices and plan for changes to reduce chloride use and determine your salt savings.
  • Obtain a Smart Salting Level 2 certification for your organization.

Organization level 2 certification – winter maintenance assessment

Organizations can earn level 2 certification by assessing their salt use using the Smart Salting tool and taking steps to minimize their salt use. Participants can obtain certification by using the tool directly or working through it in a level 2 training. 

Level 2 trainings are available each July and December. Participants earn a two-year certification that they can renew by submitting the required reports.

The tool will generate a list of current best management practices (BMPs) and a comparison of current BMPs to future BMP goals along with a salt savings assessment to estimate monetary savings due to salt reduction.

To earn level 2 certification:

  • Create an account in the Smart Salting tool.
  • Access the winter maintenance assessment section of the tool.
  • For your whole organization, branch, or facility: 
    1. Complete the Level of Service assessment. 

    2. Complete the BMP assessment for the most recently completed winter maintenance season (e.g., a January 1, 2022, report would be based on the 2020/2021 season) and future winter maintenance season.
    3. Complete the salt savings assessment. 

Submit these assessments under “Submit for Certification” on the winter maintenance assessment starting page. If the submitted assessments are complete, the tool will generate reports and a Level 2 certificate for your organization.

Chloride source assessment 

The source assessment section of the Smart Salting tool allows any organization to view an estimate of the various sources of chloride in their chosen area, whether it’s a city, county, or watershed. The tool provides more information about chloride, its sources, resources for chloride best management practices, and the option to create a personalized action plan to better understand the sources of chloride in your community and steps to reduce chloride from those sources.

NPDES permittees

There are specific pathways to guide wastewater and MS4 permittees through developing the required permit reports and plans related to chloride.

Training success stories

In Dakota County, the MPCA and its partners tracked effectiveness of Smart Salting training through two winters. Fourteen months after the county's snow plow drivers took the course, the evaluation showed measureable improvements. In the first season after the training, the county used 14,175 tons of salt for 35 snow events (average 405 tons/event). In the next season, the county used 9,585 tons of salt for 27 events (average 355 tons/event). This correlates to about 40 million gallons of freshwater protected from chloride contamination per snow event. Learn more:

Winter maintenance staff  from cities/counties and private companies who have attended the Smart Salting training have used their knowledge to reduce salt use and save their money for their organizations.
