REMINDER – Provincial: COVID-19 pressure relief extension allowances for provinces

Print this Article

During a CPA committee meeting, members expressed difficulties with maintaining the planned pressure relief valve (PRV) replacement schedule for 10-year and 25-year expiry of propane containers. 
Transport Canada (TC) has provided an extension of cylinders that fall under the Transportation of Dangerous Goods Act through the CPA’s temporary equivalency certificate TU 0807. The 10-year replacement schedule may be extended, provided that the measures indicated in the certificate are addressed.
While the Transport Canada Equivalency Certificate expires at the end of September 2021, TC will be willing to grant an extension of up to an additional year after the current extension’s expiration.
For 25-year PRV replacement schedules, the requirement and enforcement fall under provincial jurisdiction.
While not all provinces were receptive to an extension, a breakdown of provincial allowances can be found below.

1.  The province has indicated that current requirements allow for industry to catch up in the following manner (see Directive: Propane storage tank pressure relief valve servicing and inspection intervals, Technical Safety BC)

For pressure vessels in liquefied petroleum gas service governed by CSA’s B149.2 Propane Storage and Handling code, the maximum servicing intervals for PRVs are:

  • Vessels greater than 2500 USWG shall have a maximum servicing interval of 10 years;
  • Vessels 2500 USWG or less (excluding cylinders as defined by CSA B149.2) with an external PRV shall have a maximum servicing interval of 10 years; and
  • Vessels 2500 USWG or less (excluding cylinders as defined by CSA B149.2) with an internal PRV shall have a maximum servicing interval of 25 years.

2.  The frequency of the required periodic visual inspection for propane storage tank PRVs depends on the operating environment and the manufacturer’s recommendations but shall not exceed five years.

Alberta In addition to Information bulletin No. IB15-012: Servicing of Pressure Relief Valves on Propane Storage Tanks, members can receive this extension by completing the application on AB-087d - Propane Tank Safety Valve Servicing Deferral and forwarding it to the Alberta Boilers Safety Association at after completion. Once the form is reviewed and accepted, the applicant will receive a signed copy to retain for their records.
Saskatchewan The extension process is still currently under review. The CPA will update members once more information is available.

The province of Manitoba indicated that extension of PRV requirements:

 “May be considered on a case-by-case basis. Accordingly, the department is interested to hear how COVID-19 has affected member ability to comply with these requirements. To facilitate their analysis, they have asked that the CPA provide a list of all members, location of all their vessels, and an outline of the members proposed PRV replacement timeframe.”

The  CPA will not provide these specifics but members interested in an extension are invited to reach out to Cheryl Lashek, Director of Inspection and Technical Services for the Office of the Fire Commissioner, at 204-945-3328.

“An individual or company may request a variance from regulatory requirements. Variations, if granted, are specific to a single boiler or pressure vessel that has a current certificate of inspection and on a case-by-case basis.”
