Incident Narrative
"ON 12/27/2022 AT 8:08 CST AN ENTERPRISE OPERATOR MAKING ROUNDS FOUND A BLEED VALVE AT PORT ARTHUR TERMINAL LEAKING DIESEL FUEL FROM A 3-INCH LOW POINT DRAIN ON THE P110 RELIEF SYSTEM. THE BLEED VALVE WAS IMMEDIATELY ISOLATED, AND THE LEAK WAS STOPPED BY TIGHTENING THE VALVE'S FLANGED PARTS. AT 8:45 CST THE SAME DAY, ENTERPRISE PIPELINE CONTROL SHIFT SUPERVISOR WAS NOTIFIED AND A CALL WAS HELD TO DETERMINE THAT 15 GALLONS OF DIESEL HAD LEAKED FROM THE VALVE. UPON INVESTIGATION, IT WAS DETERMINED THAT WATER TRAPPED INSIDE THE VALVE BODY FROZE AND SEPARATED THE TWO-PIECE VALVE BODY CAUSING THE LEAK. TO PREVENT RECURRENCE, THE VALVE WAS REPLACED. THE LINE HAS BEEN RETURNED TO SERVICE AND ALL DIESEL FUEL HAS BEEN CLEANED UP. TRRC EMERGENCY LINE WAS CALLED ON 12/27/2022 AT 9:31 CST."
