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;
