Liquefied natural gas refuelling stations installation code

This Code applies to the design, location, construction, operation, operator training, and maintenance of LNG  refuelling stations, including mobile refuelling units, with  single containment storage tanks up to 265 cubic meters (70 000 US gallons) water capacity  employed for vehicle LNG dispensing operations.

If an LNG facility has capacity for CNG vehicle refuelling, CSA B108.1 applies to facilities downstream of the isolation valve at the outlet of the natural gas odourizer.

The scope of CSA B108.2 does not apply to the following:

a) indoor refuelling

b) marine vessel LNG fuelling facilities;

c) rail locomotive LNG fuelling facilities;

d) equipment or piping downstream of the L/CNG odourizer discharge isolation valve (see Part 1);

e) CNG equipment including storage, compression, and/or dispensing equipment;

f) equipment or piping downstream of the gas pressure regulator for closed boil-off gas systems;

g) dispensing of LNG other than into vehicle or cargo fuel tanks;

h) Liquefaction equipment;

i) LNG engine fuel systems;

j) LNG and CNG repair garages;

k) underground piping for LNG; and

l) LNG storage tank, pump and process piping when an LNG refuelling station is sharing the LNG plant storage tank
