scope:

Inclusions

This Code applies to

a) the design, location, construction, operation, operator training, and maintenance of LNG refuelling stations;

b) 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;

c) shop-fabricated and assembled refuelling stations when used to receive and store LNG to dispense LNG into vehicle fuel tanks; and

d) 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.

Exclusions

This Code does not apply to

a) indoor refuelling;

b) marine vessel LNG fuelling facilities;

c) rail locomotive LNG fuelling facilities;

d) equipment, piping, or tubing downstream of the L/CNG system odourizer's outlet isolation valve (see CSA B108.1);

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

f) CNG mobile refuelling units (MRUG) or CNG portable refuelling units (PRUG);

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

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

i) liquefaction equipment;

j) LNG engine fuel systems;

k) LNG and CNG repair garages;

l) underground piping or tubing for LNG;

m) LNG storage tanks, pumps, and process piping or tubing when an LNG refuelling station is sharing the LNG plant storage tank; and

n) 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.
