This Directive is being issued by a provincial safety manager pursuant to section 30 of the Safety Standards Act.

General details
This Directive sets out the policies for the development and documentation of safety and loss management systems for the management of safety and loss control associated with activities throughout the life cycle of a gas installation owned or operated by a gas utility.

Definitions

City gate - the plant or premises where gas received from a pipeline is metered, reduced in pressure and prepared for distribution to individual users of the gas;

Distribution main -  a pipe used for the transmission and distribution of gas at a pressure of 700 kPa gauge or less for any distance between a city gate and a service pipe

Gas - means any of the following:
(a) natural gas, manufactured gas, liquefied petroleum gas, digester gas, landfill gas, biogas or a mixture or dilution of any of them;
(b) hydrogen;

Gas company - a person or organization engaged in the sale or distribution of gas

Gas distribution system – a system of distribution mains and service pipes, and the associated control devices and service meters through which gas is conveyed

Gas installation - a facility or system, including fittings, that is owned or operated by a gas company and is used to store, convey, measure or regulate gas;

Gas utility - a gas company that owns or operates a gas installation for conveying gas from a city gate or bulk storage facility to the outlet of an individual user's meter set

Service pipe - a pipe installed by or on behalf of a gas company for the transmission of gas from a distribution main to a meter on the land or premises of the purchaser of the gas 

Specific details

As set out in Appendix 2 of Ministerial Order M 297 deposited as B.C. Reg. 209/2016 (attached to this directive), CSA Z662-15 will come into effect as of November 1, 2017. 

CSA Z662-15 Clauses 3.1 and 12.2 require companies operating distribution systems to develop and implement safety and loss management systems for the management of safety and loss control associated with activities throughout the life cycle of a pipeline system. 

The requirements for safety and loss management systems apply to the following gas equipment within the jurisdiction of the Gas Safety Regulation:

  • Distribution mains conveying gas at a pressure of 700 kPa or less between a city gate and a service pipe
  • Service pipes conveying gas at a pressure of 700 kPa or less between a distribution main and to the gas purchaser’s service meter

The owner of a gas utility holding an operating permit issued under section 28 subsection (1) (h) of the Gas Safety Regulation, shall develop and implement a safety and loss management system that includes policies, processes and procedures for the operation and maintenance of the facility which:

  • Comply with the Safety Standards Act, Safety Standards General Regulation, Gas Safety Regulation and CSA Z662
  • Set relevant company policies and performance objectives,
  • Proactively identify hazards, evaluate risks, identify and implement risk mitigations measures, and conduct inspection, maintenance, and monitoring activities,
  • Establish clear responsibilities and accountabilities,
  • Provide sufficient trained and competent persons and other resources to manage the program and,
  • Administer documentation, records reporting, evaluation and continual improvement.

Technical Safety BC manual “MAN-4057-00” provides guidance for the development, documentation and implementation of safety and loss management system. The manual will assist gas utilities to establish a safety and loss management plan relevant to the size and complexity of their facility.

Owners of gas utilities holding an operating permit issued under section 28(1) (h) of the Gas Safety Regulation are required to have documented operations and maintenance procedures as required by CSA Z662-15 for renewal of operating permits after November 1, 2017.

A review to verify a safety and loss management system may be conducted by a safety officer any time after November 1, 2017.  In accordance with section 18 (1)(k) of the Safety Standards Act, a safety officer may request a gas utility’s operation and procedure manual, records or any other documentation for monitoring or auditing as part of the verification process. Section 52 of Gas Safety Regulation requires gas companies to file standards of construction with a provincial safety manager and to produce any gas installation plan within 24 hours when requested by a safety officer.
