TGP PERSONNEL RESPONDED AND ISOLATED THE VALVE SECTION. THERE WERE NO FATALITIES NOR INJURIES REQUIRING HOSPITALIZATION. INVESTIGATION INTO THE CAUSE OF THE RUPTURE RESULTED IN THE CONCLUSION THAT THE FAILURE WAS DUE TO EXCESSIVE STRAIN FROM THE ONGOING PROGRESSION OF AN EARTH LANDSLIDE ON ONE OF THE PIPELINE'S GIRTH WELDS AND SUBSEQUENT FAILURE OF THE WELD. A CRACK IN THE GIRTH WELD ACTED AS A STRESS CONCENTRATOR AND THE DISPLACEMENT (STRAIN) OF THE PIPELINE OCCURRED THROUGH THE LANDSLIDE. EVEN IN THE ABSENCE OF A CRACK IN THE GIRTH WELD, THE LANDSLIDE LIKELY COULD HAVE RESULTED IN A PIPELINE FAILURE AT A LATER TIME IF THE LANDSLIDE REMAINED UNDETECTED AND UNMITIGATED. PART A - PIPELINE RESTART DATE ADDED. PART C - THERE WAS COMPLETE SEPARATION OF THE PIPELINE. PART B - REVISED PIPELINE STATIONING FOR INCIDENT LOCATION (MHM). PART B - RE-ENTERED ENTIRE PART B INFORMATION DELETED BY PHMSA (MHM)\n\nPHMSA trend classification: significant incident, not serious.\n\nPHMSA standardized cause: NATURAL FORCE DAMAGE — EARTH MOVEMENT.\n\nPHMSA indexed costs: $1,883,770 reported total cost, $1,052,533.651 in 1984 dollars, $2,370,996.12 in current-year dollars.\n\nPHMSA trend flags, standardized causes, and indexed costs are analytical fields added to operator-reported incident data.
