Friesen, Regional Director\nRegional Office of Motor Carriers, HMC-06\nYour memo of August 21, 1992 describes volume bottles that are filled with natural gas and\npermanently attached to truck trailers. Pipeline operators use volume bottles to provide\ntemporary sources of gas when normal sources are interrupted. You asked whether the gas\npipeline safety regulations in 49 CFR Part 192 apply to such bottles while they are transported\nover highways for refilling or for delivery to points of use.\nThe Part 192 regulations apply to any facility that is used in the transportation of natural gas by\npipeline, except for liquefied natural gas (LNG) facilities, which are covered by the regulations in\n49 CFR Part 193. Accordingly, either Part 192 or Part 193 would apply to the volume bottles\nwhen they are in use in a natural gas pipeline system. The Part 192 and Part 193 regulations do\nnot apply to volume bottles while the bottles are not part of a pipeline transportation system, as\nwhen they are transported over public highways.\n92-10-09 1","truncated":false,"body_characters":1189}
