CAN/CGSB-149.11—Radon control options for new construction in low rise residential buildings

14 Dec 2017 10:58 AM | Pam Warkentin (Administrator)

We wanted to let all our contacts know that the draft version of CAN/CGSB-149.11—Radon control options for new construction in low rise residential buildings 91.040.30 is available for a second public review period lasting 30 days. If you'd like to review the document in order to submit any comments to the CGSB (Canadian Governmental Standards Board), we've attached a pdf copy here.  CGSB-149.11-2015CD-01.pdf

We also wanted to let all CARST Members and C-NRPP Professionals know about the approval of the CGSB Standard for existing construction, CAN/CGSB-149.12-2015 CBD-01 - Radon mitigation options for existing low rise residential buildings.  After a couple of years and many hours of work by various industry stakeholders including Health Canada, CHBA, and C-NRPP professionals, we have received notice from Health Canada that it has been accepted by CGSB.  We anticipate the final document will be available free for professionals on the CGSB website.  Once it is posted, we will notify you of the location. 

All C-NRPP professionals should be familiar with this document and its requirements.  The C-NRPP Policy Advisory Board will be discussing the implementation and developing tools for C-NRPP professionals to meet the requirements and recommendations. This will be communicated to professionals shortly and will include a webinar to review the document and newly implemented C-NRPP requirements.  We will also have resources available such as mitigation labels, and a homeowner information package to help you with meeting the recommendations of the standard.

Best regards,

The CARST Team
