Radon Update

New Regulations for Radon Measurement Technicians

New regulations for Radon Testing and Mitigation were published in the New Jersey Register on June 6, 2022.  These regulations will be operative on December 3, 2022.  See the following NJ DEP Radon Section links:

Representatives of the Radon Section urge all MET’s to read the new regulations (NJAC 7:28-27A) and to read the AARST Protocols for Conducting Measurements of Radon:

Link to Radon Measurement in Homes Standard
Link to Radon Measurement in Multi-Family Homes Standard
Link to Radon Measurement in Schools & Large Buildings Standard

NOTE:  If you are not receiving notices from the Radon Section via email, please contact them.  They are no longer using the USPS to send out applications and renewal notices

What We Know

  1. All Radon MET’s who wish to continue to test residential structures after December 3 of this year must apply for their Initial Measurement Technician certification using the application sent to you from the Radon Section via email on June 8, 2022.  The application must be submitted regardless of when you submitted you last renewal application.
  2. Payment of $75 must accompany the application.
  3. The application must be submitted on or before October 3, 2022.
  4. Anyone whose current MET certification is due for renew on or after the published date of the new regulations (June 6, 2022) does not need to submit their renewal application (but should instead submit the new Initial Measurement Technician application by October 3, 2022).
  5. The new residential Radon MET designation will allow you to test for radon in one or several dwellings that are part of a shared building.  You will NOT need a Multi-family MET certification for testing a single townhouse or condominium (however, you may need it to test both halves of a side-by-side duplex — we are working to obtain clarification).
  6. NO proof of CEUs are required for the Initial Measurement Technician certification.
  7. Until December 3, 2022, continue to follow the existing rules for all radon testing and mitigation services you perform.
  8. Additional certifications (multi-family, large buildings/schools) can be applied for and received at any time; applications for the new MET categories do not have to be to the DEP by the October 3, 2022 deadline.  However, it is critical that you apply for your ‘grandfathered’ residential MET by the October 3, 2022 deadline, or you will likely have to meet the requirements for new MET certification (education, ‘The Test’, etc.).

The expiration date for the new certification will be one year from the expiration date of the certification in effect at the time of your new application.  For example:

  • If you renewed your certification on April 12, 2022, then the expiration date of your existing certification is April 12, 2023.  You must submit your application under the new rules on or before 119 days after the publication of the new rules.  If your application is approved, the expiration date of your new certification will be April 12, 2024.
  • If your renewal date is after the regulations are adopted, for example September 3, 2022, you will submit the application on or before 119 days after the publication of the rules.  After your application under the new rules is approved, the expiration date of your new certification will be September 3, 2023.

More to Come

The new regulations include a number of other change, from the need to do duplicate testing 100% of the time, to several other categories of MET certification – Multifamily Structures & Large Buildings/Schools.

More information will be provided on this page as the regulations are reviewed and clarified.
