At what point in a propane air pack-shaving facility does jurisdiction begin?\nIn a propane air peak-shaving facility liquid propane is vaporized and mixed with air to supplement natural gas supplies\nduring peak shaving. All “pipeline facilities” are within the jurisdiction of the Act. “Pipeline facilities” are defined in the\nAct to include “without limitation . . . any equipment, facility, or building used in the transportation of gas or the\ntreatment of gas during the course of transportation”(49 USC 1671 (4)). Peak-shaving facilities are an interrelated and\noften essential part of a gas distribution system and fall within the intended coverage of the term “pipeline facilities.”\nConsequently a propane air peak-shaving facility is in its entirety subject to the jurisdiction of the Act.\n2. At what point in an LNG peak-shaving facility does jurisdiction begin?\nExcept for the change in state, LNG is identical to natural gas and consequently is within the definition of the\nterm “gas” in the Act (49 USC 1671 (2)). Pipeline facilities used in the transportation of gas are subject to the jurisdiction\nof the Act. The “transportation of gas” is defined in the Act as meaning “the gathering, transmission or distribution of\ngas by pipeline or its storage in or affecting interstate or foreign commerce (49 USC 1671 (3) emphasis added). Thus, an\nLNG peak-shaving facility is within the intended coverage of the term “pipeline facilities” and therefore is in its entirety\nsubject to the jurisdiction of the Act. Additionally, it should be noted that the reasons discussed in answer to Question 1\nare equally applicable to an LNG peak-shaving facility.\nWe trust this satisfactorily answers your inquiry.\nSincerely,\nSIGNED\nCesar DeLeon\nActing Director\nOffice of Pipeline\nSafety Operations","truncated":false,"body_characters":2169}
