Review:
The Minnesota Radon Licensing Act has licensure, work practice, continuing education and reporting requirements for radon mitigation.
__________________________________________________________________________
Anyone who designs or installs a radon mitigation system in an existing non-residential building that they do not own or lease. The license allows mitigation professionals to provide on-site supervision of unlicensed radon mitigation technicians.
All mitigation professionals that are employed or contracted by a business must work under a licensed mitigation company. A sole proprietor radon mitigation professional, who does not employ or contract with a licensed radon mitigation professional, is not required to obtain a mitigation company license.
A radon mitigation professional license is a dual measurement and mitigation license. No additional license is needed to conduct measurement activities.
What you need to get licensed
Training and Exam
To be eligible for a radon mitigation professional license, applicants must:
- Complete the requirements for a measurement license listed above, plus
- Complete an approved radon mitigation course, and
- Pass an approved radon mitigation examination (the course completion exam at the end of an online course is not sufficient).
Approved courses:
Upcoming in-person courses:
Approved exams:
Important information: Both AARST-NRPP and NRSB offers technician level courses and exams. This is a lower tier of training and DOES NOT qualify a person for a MDH Radon Professional License. The student must complete the professional (NRPP) or Specialist (NRSB) course and exam.
Approved Testing Devices
Licensed professionals must submit a list of continuous monitors and passive devices that they use to measure radon. Continuous monitors used must be approved by either the NRPP or the NRSB. Passive radon devices must be analyzed by MDH licensed radon laboratories.
Quality Assurance (QA) Plan
Licensed Radon Professionals are required to submit a QA plan for measurement based on United States Environmental Protection Agency National Radon Proficiency Program Guidance on Quality Assurance. MDH has developed a QA plan template found on the forms webpage. While you are not required to use the MDH template, it has been developed to make the process as simple as possible. Currently, most of the CRM or passive device manufacturer’s templates do not meet the necessary requirements. You may modify your existing plan, modify a manufacturer’s plan, or use the MDH template.
Note: If you wish to be a radon mitigation professional but will not be placing or retrieving radon test devices, then a shorter QA plan will be acceptable. MDH will still need to know which approved radon laboratory will supply your test kits and how you will comply with section 9.2.4 of the Soil Gas Mitigation Standards.
Continuing Education and Renewal
All Minnesota radon professional licenses are valid for 1 year from the date of issuance. Professionals must apply to renew their license at least 30 days before the license expires.
In order to renew a measurement license, individuals are required to complete 12 hours of continuing education approved by MDH. Classes approved by NRPP or NRSB are automatically accepted.
Reporting Requirements
Non-residential mitigation work completed by a radon mitigation professional must be reported to MDH by a licensed radon company or a licensed sole proprietor mitigation professional. These reports are due quarterly (January 30, April 30, July 30, October 30) and must be submitted online through the radon licensing system. The specific data to be submitted are described in the
Licensing for Radon Professionals
Measurement work completed by a radon mitigation professional must also be reported. The specific data to be submitted are described in the
Licensing for Radon Professionals. Pre- and post-mitigation radon concentration results conducted or collected as part of the non-residential mitigation work are to be reported as part of the company’s mitigation reporting.
Standards of Conduct and Work Practices
Radon mitigation professionals must follow standards of conduct and work practices:
- Operate according to the QA Plan approved under the license
- Use measurement devices approved by NRPP or NRSB
- Notify the commissioner of any change to the license within 30 days
- Maintain proof of license while on a project site
- Use only radon laboratories licensed by MDH
- Maintain radon test and calibration records for 3 years
- Not interfere with MDH inspection or audit
- Comply with ANSI/AARST protocols for conducting radon measurement in homes, multifamily buildings and schools/large commercial buildings
- Comply with ANSI/AARST protocols for conducting radon mitigation in schools/large commercial buildings
- Make available, to MDH, records, equipment, addresses, property owners, residents, and employees
Radon System Tags and Post-Mitigation Checklist
All non-residential mitigation systems installed by professionals must have a MDH issued tag. Licensed mitigation companies or sole proprietor can purchase tags. A mitigation professional must complete a post-mitigation checklist upon completion of the system installation, using the form available by MDH. The system tag must be attached by a licensed mitigation professional in the interior of building, next to the system pressure gauge, in a visible location and on the date of project completion.
