How can I become a registered facility under CSA B620?

The registration requirements for a facility are addressed in Clause 8 of CSA B620 standard, however, an application form has been developed to facilitate the registration process. Facilities wishing to manufacture, modify, assemble, repair, test, and/or inspect highway tanks and/or TC portable tanks pursuant to CSA-B620 standard must complete the form entitled "Application for registration as a facility for the manufacture, modification, assembly, repair, testing, and/or inspection of highway tanks and/or TC portable tanks pursuant to clause 8.1.4 of CSA-B620 (click here for a sample application) and submit the form and required supporting documents to the Director. 

An applicant must possess a quality control manual that satisfies the requirements of Appendix B of CSA B620 in respect of the facility but need not submit the manual with the application. The manual is subject to audit by TDG Inspectors at any time. Clause 2.2 of Appendix B in CSA B620 provides section headings that must be used in the quality control manual and a description of what each section must address. Each registered facility must have, maintain and adhere to a quality control manual that is in conformity with Appendix B of CSA B620.

Facilities wishing to register to manufacture, modify or repair specification 407 tanks with an MAWP of greater that 35 psig other than such tanks made of fibre reinforced plastic, highway tanks loaded by vacuum other than such tanks made of fibre reinforced plastic, or other highway or portable tanks with MAWP greater than 15 psig, must obtain the appropriate Certificate(s) of Authorization required by Clause 8.1.3 of CSA-B620 and must submit a copy of any such Certificate(s) with the application. Clause 8.1.3 also requires facilities to possess a Certificate of Authorization to manufacture, modify, and repair piping for these tank types.

The Director will register a facility and issue a Certificate of Registration where the Director is satisfied that the applicant has demonstrated familiarity with the requirements of the standard and the capability to consistently meet the requirements of the standard. A Certificate of Registration is normally valid for a period of five years and is contingent upon favourable facility inspections that may be performed during the registration period.

How can I request an amendment to an existing registration?

A facility registered with Transport Canada pursuant to CSA B620 must submit an application for an amendment to a Certificate of Registration to the Director when there is a change to the information previously submitted to the Director for the purpose of obtaining a Certificate of Registration or when the facility wishes to request a change in the scope of its existing registration. Facilities must complete the form entitled "Application for registration as a facility for the manufacture, modification, assembly, repair, testing, and/or inspection of highway tanks and/or TC portable tanks pursuant to clause 8.1.4 of CSA-B620 " and submit the form and required supporting documents to the Director. Depending on the nature of the amendment, the facility may be required to obtain new or revised Certificates of Authorization in order to comply with Clause 8.1.3 of CSA-B620. Facilities are required to update their quality control manual to reflect any changes in scope of work.

The Director may issue a revised Certificate of Registration where the Director is satisfied that the applicant has demonstrated familiarity with the requirements of the standard and the capability to consistently meet the requirements of the standard depending on the nature of the amendment. This Certificate of Registration will replace any Certificate of Registration previously issued to the facility.

How do I renew my expiring Certificate of Registration?

Facilities wishing to renew a Certificate of Registration authorising the manufacture, modification, assembly, repair, test, and/or inspection of highway tanks and/or TC portable tanks pursuant to CSA B620 standard must complete the form entitled "Application for registration as a facility for the manufacture, modification, assembly, repair, testing, and/or inspection of highway tanks and/or TC portable tanks pursuant to clause 8.1.4 of CSA-B620 " and submit the form and required supporting documents to the Director in the same manner as for an initial application. Facilities are expected to submit an application for renewal at least three months prior to the expiry date of the Certificate of Registration.

The Director may issue a new Certificate of Registration where the Director is satisfied that the applicant has demonstrated familiarity with the requirements of the standard and the capability to consistently meet the requirements of the standard. This Certificate of Registration will replace any Certificate of Registration previously issued to the facility.

How do I change the certificate holder name on a Certificate of Registration?

A Certificate of Registration is issued to an individual or to a corporate entity who is the certificate holder. A Certificate of Registration may not be conveyed from one certificate holder to another. A name change on a Certificate of Registration is only permitted if the certificate holder remains the same individual or corporate entity as before. In such a case the certificate holder may submit a written request to the Director. The request must include the facility registration number, the new certificate holder name, a justification that the conditions for name change apply, the date on which the change is proposed to become effective, and documentation to confirm the certificate holder’s new legal name. If the certificate holder is not the same individual or corporate entity as before, an application requesting an amendment to an existing registration must be submitted to the Director.

How is the design of a pressure tank approved?

A "pressure tank" is a specification 407 tank with an MAWP of greater that 35 psig other than such tanks made of fibre reinforced plastic, a highway tank loaded by vacuum other than such tanks made of fibre reinforced plastic, or other highway or portable tank with MAWP greater than 15 psig. Once the applicant has performed the design and is satisfied that all the applicable requirements of CSA-B620 are satisfied, the applicant must prepare and submit the complete design and all supporting calculations, drawings and documentation to a Transport Canada Designated Agency for design review.  The Designated Agency will review the design for conformity to CSA B620 on a fee for service basis for the submitter and will issue a written report with respect to compliance with CSA-B620 to the submitter.  The Submitter may be the highway tank or portable tank manufacturer, or may be an assembler or modifier.  The design review must address the scope activities performed by the applicant on a design.  If the report indicates that the tank satisfies the requirements of the standard, the applicant must submit the report to the Director as part of an application for a TCRN (Transport Canada Registration Number) as required in Clause 8.3.3 of CSA B620.  The TCRN for a "pressure" highway or portable tank is required to be marked on the tank nameplate fo each tank built to that design.

How is the design of a non-pressure tank approved?

A Design Engineer registered by Transport Canada must review the tank design in accordance with 8.3.1 of CSA-B620.  The Design Engineer must be registered by Transport Canada but may be an employee of the manufacturer.  If the design is found to satisfy all the applicable requirements of the CSA B620 standard the manufacturer must then issue a unique Manufacturer's Design Identification Number (MDIN) for that tank design which is required to be marked on the tank nameplate of each tank built to that design.

How do I register as a Design Engineer?

The registration requirements for a Design Engineer are addressed in Clause 8 of CSA B620 standard, however, an application form has been developed to facilitate the registration process. Individuals wishing to register as a Design Engineer pursuant to CSA-B620 standard must complete the form entitled "Application for registration as a Design Engineer pursuant to Clause 8.1.5 of CSA-B620" and submit the form and required supporting documents to the Director.

The Director will register a Design Engineer and issue a Certificate of Registration where the Director is satisfied that the applicant has demonstrated familiarity with the requirements of the standard and the capability to consistently meet the requirements of the standard. A Certificate of Registration is normally valid for a period of five years.

How do I renew my expiring Certificate of Registration as a Design Engineer?

Design Engineers wishing to renew a Certificate of Registration that has been issued pursuant to CSA-B620 standard must complete the form entitled "Application for registration as a Design Engineer pursuant to Clause 8.1.5 of CSA-B620" and submit the form and required supporting documents to the Director in the same manner as for an initial application.
