Incident Narrative
"ON AUGUST 4, 2018 AT 9:00 AM, SUPERIOR TERMINAL PERSONNEL DISCOVERED A LEAK ON VALVE 272 ATTACHED TO TANK 17. APPROXIMATELY 7.5 GALLONS OF CRUDE OIL HAD BEEN RELEASED FROM THE VALVE, THE LEAK ORIGINATED FROM THE 1/2"" BODY BLEED CONNECTION TO THE VALVE BODY. THIS 8"" VALVE WHICH IS ATTACHED TO THE TANK IS BLINDED OFF. A SMALL AMOUNT OF PRODUCT WAS SPRAYED ONTO THE SURROUNDING SOIL. LESS THAN A CUBIC YARD OF CONTAMINATED SOIL WAS REMOVED AND TAKEN TO THE SOIL MANAGEMENT SITE FOR PROPER DISPOSAL. ON AUGUST 10, 2018, DURING A SCHEDULED OUTAGE, TANK 17 WAS PUMPED DOWN TO WORKING BOTTOMS TO ACCOMMODATE THE INVESTIGATION AND REPAIR OF THE VALVE. IT WAS DISCOVERED THAT THE RELEASE WAS DUE TO THERMAL PRESSURE BUILDUP. THE VALVE WAS SECURED IN THE PARTIALLY OPEN POSITION TO PREVENT FURTHER THERMAL PRESSURE BUILDUP IN THE FUTURE. 09/24/2024 - UPDATED BY PHMSA PER OPERATOR APPROVAL."
