Rulemaking for Radon Licensing in Minnesota
Indoor Air Unit
The 2015 Minnesota Legislature passed the Minnesota Radon Licensing Act, Minnesota Statutes 144.4961, which was signed into law in May 2015. The Act gives MDH the authority to write rules and enforce laws related to the radon industry. There were statute changes in both the 2016 and 2017 legislative sessions. The latest changes push back the rule implementation date to January 1, 2019. On July 1, 2015, MDH began the rule making process and will complete the rule making process in 2018. Beginning January 1, 2019, the rules developed will go into effect. Professionals and companies that measure for radon, mitigate for radon or perform radon analysis in the State of Minnesota will be required to be licensed and use system tags.
There are currently no requirements for professionals. All licensing requirements will begin January 1, 2019.
