    CSA B108.1:21 - Compressed natural gas refuelling stations installation code


    Preface


    This is the first edition of CSA B108.1, Compressed natural gas refuelling stations installation code. It supersedes the previous editions published in 2018 as Part 1 of CSA B108, Natural gas refueling stations installation code, and in 2014, 1999, and 1995 as CSA B108, Compressed natural gas fueling stations installation code.


    CSA B108.1 is applicable to compressed natural gas (CNG) refueling stations. CSA B108.2 is applicable to liquefied natural gas (LNG) refuelling stations, including LNG to CNG conversion systems. CSA B108.2 supersedes Annex D of CSA Z276, Liquefied natural gas (LN) — Production, storage, and handling.


    Significant changes to this edition include the following:


    a) reorganized content for consistency of organization between this Code and CSA B108.2;


    b) clarification of definitions, and requirements to include distinction between residential fueling appliances (RFAs) and listed non-residential vehicle fuelling appliances (VFAs);


    c) added coverage for defuelling;


    d) added coverage for mobile refuelling units and portable refueling units;


    e) added reference content for Risk assessment;


    f) added coverage for CNG stations where feedstock is liquefied natural gas (L/CNG refueling stations); and


    g) editorial revisions to clarify wording and references, tables and figures, resolve conflicts identified with other documents, provide consistency and clarification between this Code and CSA B108.2, correct metrication values, and harmonize definitions with other industry codes and standards.


    CSA Group acknowledges that the development of this Code was made possible, in part, by the financial support of Natural Resources Canada.


    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 all compressed natural gas (CNG) refueling stations, including those that are fixed or mobile and intended for private or public dispensing operations.


    1.2 Exclusions


    This Code does not apply to


    a) refuelling vehicles with liquefied natural gas (LNG). Refuelling vehicles with LNG is addressed in CSA B108.2. However, when an LNG facility has capacity for CNG vehicle refuelling, this Code applies to facilities downstream of the L/CNG odorizer’s outlet isolation valve;


    b) transfer of CNG from the CNG vehicle fuel storage system of one vehicle to the CNG vehicle fuel storage system of another vehicle. This does not apply to a bulk container; and


    c) listed residential fuelling appliances (RFAs) and listed non-residential vehicle fuelling appliances (VFAs), except where


    i) the aggregate inlet flow capacity of a connected VFA or RFA, or a combination thereof, exceeds 0.850 Sm3/min (30 SCFM); or


    ii) the VFA or RFA is connected to storage, in which case coverage applies to the storage and dispensing system starting at the outlet of the individual VFA or RFA (see Figure D.1).


    1.3 Pressure terminology


    All references to pressure throughout this Code are to be considered gauge pressures, unless otherwise specified.


    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 imperial units to metric 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 developed originally using the imperial system of measurement and subsequently converted to metric units having three significant digits. Every attempt has been made to provide accurate conversion values; however, when designing systems using these values, engineering judgment needs to be applied.

    CSA B108.2:21 - Liquefied natural gas refuelling stations installation code


    Preface


    This is the first edition of CSA B108.2, Liquefied natural gas refuelling stations installation code. It supersedes the previous edition published in 2018 as Part 2 of CSA B108, Natural gas refuelling stations installation code.


    CSA B108.1 is applicable to compressed natural gas (CNG) refueling 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 (LN) — Production, storage, and handling.


    Significant changes to this edition include the following:


    a) reorganized content for consistency of organization between this Code and CSA B108.1;


    b) clarification of definitions, and requirements to include distinction between residential fueling appliances (RFAs) and listed non-residential vehicle fuelling appliances (VFAs);


    c) added coverage for defuelling;


    d) added coverage for mobile refuelling units and portable refueling units;


    e) added reference content for risk assessment;


    f) added coverage for CNG stations where feedstock is liquefied natural gas (L/CNG refueling stations); and


    g) editorial revisions to clarify wording and references, tables and figures, resolve conflicts identified with other documents, provide consistency and clarification between this Code and CSA B108.1, correct metrication values, and harmonize definitions with other industry codes and standards.
