Directive: CNG fueling site requirements
This Directive is being issued by a provincial safety manager pursuant to section 30 of the Safety Standards Act.
This Directive is to clarify British Columbia Safety Authority (BCSA) requirements for compressed natural gas (CNG) dispensing equipment installations and operation in relation to the Gas Safety Regulation (GSR) under the Safety Standards Act (SSA).
Prior to installation of a CNG fueling station site and related equipment (dispenser), the owner (or representative) of the same must apply for a design registration in order to have the equipment and site design accepted before installation work is to commence.
Design Registration Requirements
Applications for design registration regarding a CNG fueling station site and related equipment, must contain all drawings, specifications, calculations and instructions necessary to construct, install, operate and maintain equipment, as it may apply to the below-mentioned codes and standards. The application must also contain a statement of compliance to the below-mentioned codes, standards and practice documents that is signed and sealed by a professional engineer. The design documents shall be sealed by a professional engineer who is registered with the Association of Professional Engineers and Geoscientists of BC.
All CNG fueling station sites and related equipment must comply with an approved standard. The associated recognized standards with applicable sections are;
a) CSA B149.1 Natural Gas/Propane Installation Code - adopted under regulation.
b) CSA Z662 Oil and gas pipeline systems Code - adopted under regulation.
c) CSA-B108 Natural Gas Fuelling Stations Installation Code - adopted under regulation
Applicable clearance, setback, protection and other rules concerning stationary gas equipment may apply under the referenced recognised codes/standards or other recognized document depending on how the equipment has been sited (e.g., permanently attached versus still on wheels ready-to-tow). Therefore, design submissions for BCSA approval should account for compliance based on all expected modes of operation including total CNG storage capacities at any given time on the site. Significant changes to modes of operation or modifications of existing installations such as change in container capacities or location (permanent or non-permanent) on the site must be re-submitted for approval to BCSA.
Municipalities, local fire departments, Transport Canada, Environment Canada and other Ministries of both Federal and Provincial Governments may have approval/permit requirements for other aspects of CNG fuelling station operations such as the business, overall site and non-dispensing equipment. BCSA approval does not constitute approval by any other regulatory body or agency. The applicant is responsible for identifying and complying with any applicable requirements and agencies that administer those requirements. Validation documentation from the above noted or other applicable agencies shall be submitted to BCSA prior to issuance of the final Operating permit.
After a design registration has been accepted, an appropriate installation permit and an application for a Class 3G – Natural Gas Dispenser operating permit must be in place before construction takes place. In addition, there must also be an installation permit in place before any modifications are made. Replacement of items of equipment during normal maintenance will not be construed as a modification of an installation.
Consideration of future development – When selecting locations, due consideration must be given to the development plans of the area. If a building permit has been issued for the area around a proposed installation, such future development needs be taken into consideration in the design and application for acceptance of the installation.
Design approval by BCSA is restricted to acceptance for the purposes of approving the dispensing equipment and any other SSA-regulated products only.
