Michigan Rulemaking on Radon-resistant New Construction
“ In July 2022, the Michigan Radon Program collaborated with a radon-resistant new construction (RRNC) stakeholder group to submit proposed updates to the state’s Residential Building Code. The proposed changes would expand RRNC requirements to all 83 Michigan Counties. (Nine counties currently have RRNC requirements in place.) The rulemaking process on Michigan’s Residential Building Code is expected to take approximately 12 months.”
Several Counties, including Washtenaw County, have already adopted Appendix F. https://www.washtenaw.org/176/Radon-Requirements
Overview of EPA’s State and Tribal Indoor Radon Grants Program: A Focus on Activities Conducted During 2022, published in February 2023, notes this as an accomplishment. (https://www.epa.gov/system/files/documents/2023-02/2022%20Annual%20SIRG%20Activities%20Report.pdf)
