AB: Updates to government’s STANDATA for engines and turbines

The Alberta government has posted new STANDATA bulletin 20-GCB-001: Engines and turbines.

The update includes changes to the variance required. The former variance was VAR-GAS 03-19 and has been changed to the new wording:

An engine or turbine may be certified or approved by an inspection body (IB), an engineer under variance 20-GCV-02[REV1] Engineer authentication at oil and gas production facilities, or accepted by a Safety Codes Officer under variance 20-GCV-01[REV1] Stationary gas engines.

To clarify existing requirements and facilitate new technologies, the national gas code technical committees supported moving the requirements for engine fuel components from the installation code to the field approval code. Alberta supports national code and standard development across Canada; the 2020 versions of the B149 gas codes referenced in the Gas Code Regulation came into force February 1, 2021.

Referenced gas codes are applicable from the date of adoption, are not retroactive, and would not apply to legacy equipment. The owner is responsible under the Safety Codes Act to ensure their installations are compliant with related regulations and codes at the time of installation.
