TCRNs and B620-14 – How Transport Canada will process applications pre B620-14 adoption
Existing TCRNs have been issued to CSA standards B620-09, B620-03 and B620-98. Since each subsequent edition of B620 incorporates changes over the intervening years, some of these existing TCRNs will not be compliant with B620-14 and the TDG Regulations once B620-14 is adopted into the TDG Regulations.
The following processes are immediately applicable to ensure that industry has a means of manufacturing and assembling compliant tanks during the transition from B620-09 to B620-14.
Scenario 1 – Renewing/updating existing B620-09 TCRNs to B620-14
The TCRN design holder (B620 registered facility) must review and update their design, then submit a design package to a Designated Design Review Agency (DRA) demonstrating compliance with B620-14. This submission may be a complete design package, a design package detailing only the changes to an existing design, or a package that demonstrates that no changes are required for B620-14 compliance, at the discretion of the DRA. If the DRA is satisfied, they will issue a report to Transport Canada (TC) recommending a TCRN. If the TCRN requires no changes for compliance, TC will renew the TCRN in accordance with B620-14. If changes are required to bring the design into compliance with B620-14, TC will issue a new TCRN. This new TCRN issued to B620-14 will only become valid once B620-14 has been adopted in the TDG Regulations. Until then, existing TCRNs issued to B620-09 will remain valid.
Scenario 2 – New design submitted prior to adoption of B620-14
If the DRA issues a report indicating that a new design is compliant with B620-09 and B620-14, TC will issue a TCRN that is valid for B620-09 and B620-14. This TCRN will become valid upon issuance (while B620-09 is still in effect) and will automatically remain valid up to the expiry date identified on the TCRN or until B620-14 is superseded in the TDG Regulations.
If the DRA issues a report indicating that a new design is compliant to B620-09, TC will issue a TCRN to B620-09. It will remain valid until B620-14 is adopted into the TDG Regulations.
If the DRA issues a report indicating that a new design is compliant to B620-14, TC will issue a TCRN to B620-14. This TCRN will not become valid until B620-14 is adopted into the TDG Regulations.
