Part 1 of this Code applies to all compressed natural gas refuelling stations, including those that are intended for fleet or public dispensing operations.
Part 1 of this Code does not apply to refuelling vehicles with liquefied natural gas (LNG). Refuelling vehicles with LNG is addressed in Part 2 of this Code.
However, if an LNG facility has capacity for CNG vehicle refuelling, Part 1 of this Code applies to facilities downstream of the isolation valve at the outlet of the natural gas odourizer.
Part 1 of this Code does not apply to listed residential fuelling appliances (RFAs) and listed nonresidential vehicle fuelling appliances (VFAs) except where
a) the aggregate inlet flow capacity of a connected VFA or RFA, or a combination thereof, exceeds 0.850 Sm3/min (30 SCFM), or
b) 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 B.1).
All references to pressure throughout Part 1 of this Code are to be considered gauge pressures, unless otherwise specified.
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; "may" is used to express an option or that which is permissible within the limits of the code; and "can" is used to express possibility or capability.
