Radon Task Group (TG) Meeting
Radon Task Group (TG) Meeting
July 11, 2024
The Task Group met to review proposed changes form (PCF) 1713 (Passive vertical radon stack) in response to motions made at the June 18-20, 2024 Standing Committee on Housing and Small Buildings (HSB) meeting in Ottawa:
- The Task Group reached an agreement on the revised wording for the exception for stair landings.
- The Task Group reached an agreement on referring to the updated clauses in CGSB 149.11.
- The Task Group could not reach an agreement on the new proposed note in support of active (with fan) radon mitigation systems.
It’s not known if there is time for the Task Group to review the two recently updated CGSB radon standards within the 2025 Code cycle.
The proposed note will not help builders avoid having to apply for an alternative solution which can be very challenging and costly.
The Task Group discussed the possibility of following up with the Board and HSB chair to seek direction on what should be done next given the tight timelines. Staff was to follow up with senior Technical Advisors regarding the next steps. In the meantime, the Task Group meeting scheduled for the following day was cancelled that evening.
A discussion on revisions to PCF 1993 (Radon and soil gas mitigation, sealed overlapping seams for air barriers on the ground) was deferred to a future meeting.
