Question: Under the Natural Gas Pipeline Safety Act of 1968, at what point in a propane air peak-shaving facility does jurisdiction begin?

OPSO Interpretation: ..."In a propane air peak-shaving facility, liquid propane is vaporized and mixed with air to supplement natural gas supplies during peak shaving. All 'pipeline facilities' are within the jurisdiction of the Act. 'Pipeline facilities' are defined in the Act to include 'without limitation . . . any equipment, facility, or building used in the transportation of gas or the treatment of gas during the course of transportation' (49 USC 1671(4)). Peak-shaving facilities are an interrelated and often essential part of a gas distribution system and fall within the intended coverage of the term 'pipeline facilities.' Consequently, a propane air peak-shaving facility is in its entirety subject to the jurisdiction of the Act."
