GULF SOUTH PIPELINE COMPANY, LLC

Incident Narrative

ON OCTOBER 28, 2020 AT APPROXIMATELY 13:15, GULF SOUTH'S GAS CONTROL RECEIVED A CALL REPORTING A WRECK ON HIGHWAY 16 IN ISABEL, LOUISIANA THAT INVOLVED A PIPELINE AND FIRE. GAS CONTROL DISPATCHED LOCAL OPERATIONS PERSONNEL AND, AFTER NOTICING A SLIGHT PRESSURE DROP FOLLOWED BY AN INCREASED FLOW AT MANDEVILLE JUNCTION, LOWERED THE PRESSURE ON THE NEAREST REGULATOR. AT APPROXIMATELY 13:41 GULF SOUTH PERSONNEL WERE ONSITE. IT WAS NOT IMMEDIATELY CLEAR WHETHER GULF SOUTH ASSETS WERE IMPACTED BECAUSE BOTH GULF SOUTH AND CENTERPOINT HAVE FACILITIES IN THE IMMEDIATE AREA; THE AREA MANAGER COORDINATED WITH CENTERPOINT PERSONNEL TO IDENTIFY WHICH ASSETS WERE INVOLVED. IN THIS AREA, GULF SOUTH'S INDEX 301-4-2-14 RUNS PARALLEL TO HIGHWAY 16. A 1-INCH LINE FROM INDEX 301-4-2-14 CROSSES HIGHWAY 16 AND FEEDS A CENTERPOINT METER. AT 14:00, THE AREA MANAGER REPORTED THAT THE ACCIDENT INVOLVED A FATALITY AND THAT THEY WERE DIGGING DOWN TO THE VALVE TO SHUT OFF GAS FLOW. AT 14:33 GULF SOUTH TAP WAS SHUT OFF AND IT WAS CONFIRMED THAT THE LEAK WAS ON A GULF SOUTH 1"" RISER. HIGHWAY 16 WAS BLOCKED OFF, AND AT APPROXIMATELY 14:35 THE FIRE WAS OUT. AT 14:47 NRC NOTIFICATION WAS MADE. OPERATIONS PERSONNEL REPORTED THAT AN 18-WHEELER LOG TRUCK WAS SITTING ON TOP OF THE RISER AND HAD BEEN BURNED. THE DRIVER OF THE 18-WHEELER LOG TRUCK DID NOT HAVE SIGNIFICANT INJURIES. THE FATALITY WAS THE DRIVER OF THE SECOND VEHICLE WHICH WAS CAUSED BY VEHICULAR IMPACT AND NOT THE RESULT OF THE GAS RELEASE OR FIRE. GULF SOUTH COMPLETED REPAIRS TO ITS FACILITIES ON OCTOBER 29, 2020. THE RESPONSES PROVIDED FOR QUESTIONS D3, E1, E1A, E2, E2A, E2B, AND E2C PERTAIN TO THE 4-INCH PARENT PIPE (INDEX 301-2-4-14) BECAUSE THE INCIDENT OCCURRED ON A FARM TAP. THE RESPONSE TO QUESTION D7A IS ZERO BUT THE ACTUAL NUMBER IS UNKNOWN. THIS INCIDENT INCLUDED VEHICLE DAMAGE AND A DEATH BUT THOSE WERE NOT GULF SOUTH'S RESPONSIBILITY AND GULF SOUTH HAS NO KNOWLEDGE OF THE COST ASSOCIATED WITH THESE DAMAGES.
