Consists of CSA B108.1:23, Compressed natural gas refuelling stations installation code and CSA B108.2:23, Liquefied natural gas refueling stations installation code

Scope
1.1 Inclusions

This Code applies to

  1. the design, location, construction, operation, operator training, and maintenance of CNG vehicle refuelling stations
  2. and CNG bulk transport filling and decanting stations, including i) those that are fixed or mobile and intended for private or public dispensing operations; and ii) bulk transport filling and decanting stations that feed CNG pressure reduction stations or other non-vehicle uses
1.2 Exclusions

This Code does not apply to

  1. refuelling vehicles with liquefied natural gas (LNG), which is covered by CSA B108.2. However, when an LNG facility has capacity for CNG vehicle refuelling from a liquid to compressed natural gas system (L/CNG system), this Code applies to facilities downstream of the L/CNG system odourizer's outlet isolation valve
  2. transfer of CNG from the CNG vehicle fuel storage system of one vehicle to the CNG vehicle fuel storage system of another vehicle
  3. listed residential fuelling appliances (RFAs), listed non-residential vehicle fuelling appliances (VFAs), and listed vehicle refuelling appliances (VRAs), except where i) the aggregate flow capacity of a connected refuelling appliance (RA), or a combination of refuelling appliances thereof, exceeds 0.850 Sm3/min (30 SCFM); or ii) the RA is connected to storage, in which case coverage applies to the storage and dispensing system starting at the outlet of the individual RA (see Figure D.1)
  4. and mobile equipment containing compressed natural gas, such as MRUGs, PRUGs, and bulk containers in the act of being transported or offered for transport in accordance with Transport Canada's Transportation of Dangerous Goods Act and Regulations
1.3 Pressure terminology

Unless otherwise specified, all references to pressure throughout this Code are to be considered gauge pressures.

1.4 Terminology

In this Code, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Code; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Code. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.5 Use of SI units

The values given in SI units are the units of record for the purposes of this Code. The values given in parentheses are for information and comparison only. Notes: 1) IEEE/ASTM SI 10 or ISO 80000-1 can be used as a guide when converting U.S. customary units to SI units. 2) Where the abbreviation "gal" is used in this Code, it indicates a U.S. gallon equivalent to 3.785 L water capacity. 3) This Code was originally developed using the U.S. customary system of measurement and subsequently converted to SI units having three significant digits. Every attempt has been made to provide accurate conversion values; however, when designing systems using these values, engineering judgment should be applied. -------------------------------------------------------------------------------------------------------------------------------------------------------------------- CSA B108.2:23 - Liquefied natural gas refueling stations installation code Preface This is the second edition of CSA B108.2, Liquefied natural gas refuelling stations installation code. It supersedes the previous editions published in 2021 and 2018 as Part 2 of CSA B108, Natural gas refuelling stations installation code. CSA B108.1 is applicable to compressed natural gas (CNG) refuelling stations. CSA B108.2 is applicable to liquefied natural gas (LNG) refuelling stations, including LNG to CNG conversion systems. This Code supersedes Annex D of CSA Z276, Liquefied natural gas (LNG) — Production, storage, and handling. The following are the major changes to this edition

  1. reorganization and revisions of content for consistency of organization between this Code and CSA B108.1
  2. clarification of definitions and requirements
  3. clarification of requirements for liquid to compressed natural gas (L/CNG) pumps
  4. clarification of such terminology as "flammable liquids" and "natural gas in liquid or gaseous form"
  5. updated language and general requirements for L/CNG stations
  6. editorial revisions to i) clarify wording and references, tables, and figures; ii) resolve conflicts identified with other documents; iii) provide consistency and clarification between this Code and CSA B108.1; iv) correct metrication values
  7. and harmonize definitions with other industry codes and standards. CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada.

This Code was prepared by the Subcommittee on Natural Gas for Vehicle Refuelling Stations Installation Code, under the jurisdiction of the Technical Committee on Natural Gas Transportation and the Strategic Steering Committee on Transportation, and has been formally approved by the Technical Committee. This Code has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group

Scope
1.1 Inclusions

This Code applies to

  1. the design, location, construction, operation, operator training, and maintenance of LNG refuelling stations
  2. LNG mobile refuelling units (MRUL) or LNG portable refuelling units (PRUL) with single containment storage tanks up to 265 m3 (70 000 gal) water capacity employed for vehicle LNG dispensing operations
  3. shop-fabricated and assembled refuelling stations when used to receive and store LNG to dispense LNG into vehicle fuel tanks
  4. and the LNG portion of stations that vapourize and pressurize LNG to obtain CNG, up to and including the odourizer's outlet isolation valve.

Note: When a refuelling station dispenses fuels in addition to LNG, this Code applies only to the LNG refuelling system and equipment

1.2 Exclusions

This Code does not apply to

  1. indoor refuelling
  2. marine vessel LNG fuelling facilities
  3. rail locomotive LNG fuelling facilities
  4. equipment, piping, or tubing downstream of the L/CNG system odourizer's outlet isolation valve (see CSA B108.1)
  5. CNG equipment including storage, compression, and/or dispensing equipment
  6. CNG mobile refuelling units (MRUG) or CNG portable refuelling units (PRUG)
  7. equipment, piping, or tubing downstream of the gas pressure regulator for closed boil-off gas systems
  8. dispensing of LNG other than into vehicle or cargo fuel tanks
  9. liquefaction equipment
  10. LNG engine fuel systems
  11. LNG and CNG repair garages
  12. underground piping or tubing for LNG
  13. LNG storage tanks, pumps, and process piping or tubing when an LNG refuelling station is sharing the LNG plant storage tank
  14. and transfer of LNG from the LNG vehicle fuel storage system of one vehicle to the LNG vehicle fuel storage system of another vehicle.

Note: This does not apply to a bulk fuel storage system
