Minnesota Radon Rules
For clarification, Randy, you are quoting an old version of the rule. I have copied the relevant section of the rule and also posted a link to the full rule. The current rule for mitigation has similar language.
§Subp. 4. Expiration; renewal; continuing education.
A. A radon measurement professional license is valid for one year from the date of issuance.
B. A radon measurement professional may apply to renew a license after completing eight hours of continuing education approved by the commissioner under part 4620.7700.
C. To renew an expired license, an applicant must submit a renewal application by submitting the information required under subpart 5 and must:
(1) complete eight hours of continuing education approved by the commissioner under part 4620.7700 for every year or part of a year that the license has lapsed;
(2) complete an initial radon measurement course approved by the commissioner under part 4620.7700; or
(3) pass a radon measurement examination as approved by the commissioner under part 4620.7700.”
