Incident Narrative
"AT APPROXIMATELY 19:44 CT ON 08/03/2020, ENTERPRISE PIPELINE CONTROL RECEIVED A HAZARDOUS GAS DETECTOR ALARM AT THE MONT BELVIEU SOUTH TERMINAL. AN ENTERPRISE EMPLOYEE WAS DISPATCHED TO THE SITE ARRIVING AT 20:30. THE SOURCE OF THE RELEASE WAS LOCATED AND LINE WAS ISOLATED. ENTERPRISE BLEW DOWN APPROXIMATELY 1300 BARRELS TO REDUCE LINE PRESSURE TO 0 PSI, MONITORING LEL LEVELS THROUGHOUT. A GASKET ON A VALVE FAILED ALLOWING PRODUCT TO ESCAPE. THERE WAS NO INDICATION THAT THE PRESSURE EXCEEDED THE MOP OF THE SYSTEM AND THE ENTERPRISE SYSTEM WAS NOT FLOWING AT THE TIME OF THE RELEASE. THE FAILED GARLOCK GASKET WAS REPLACED WITH A FLEXITALLIC GASKET TO STOP THE LEAK FROM RECURRING. GARLOCK GASKETS WILL BE REPLACED WITH FLEXITALLIC GASKETS WITHIN THIS FACILITY TO PREVENT RECURRENCE OF A SIMILAR EVENT. NRC INITIAL CALL # 1283608, NRC 48-HR FOLLOW-UP # 1283776."
