Incident Narrative

ON JANUARY 20, 2018 AT APPROXIMATELY 15:15 CST, A FIELD OPERATOR WAS PERFORMING A GENERAL MAINTENANCE ACTIVITY BY COMPLETING A TEMPERATURE CHECK (FN-151-TIT-1008A) ON THE LINE 55 CUSTODY TRANSFER HEADER IN THE FLANAGAN SAMPLE BUILDING. THE FIELD OPERATOR INADVERTENTLY LOOSENED THE THERMOWELL WHILE TRYING TO REMOVE THE THERMOWELL CAP, WHICH RESULTED IN A CRUDE OIL RELEASE OF 15 GALLONS. THE EDMONTON CONTROL CENTER OPERATOR RECEIVED A HIGH LEL ALARM IN THE LINE 55 SAMPLE BUILDING AND CONTACTED THE FIELD OPERATOR FOR VERIFICATION OF PRODUCT RELEASE. UPON CONFIRMATION, LINE 55 WAS IMMEDIATELY SHUT DOWN AT 15:20 CST, WHICH PREVENTED FURTHER RELEASE OF PRODUCT. THE THERMOWELL WAS REINSERTED INTO THE PIPE BY THE ON-CALL MAINTENANCE TECHNICIAN AND LINE 55 WAS RESTARTED AT 17:55 CST. APPROXIMATELY 14.75 GALLONS OF PRODUCT WAS CONTAINED WITHIN THE SAMPLE BUILDING AND WAS RECLAIMED THROUGH THE SUMP TANK. THE REMAINING 1 QUART OF CRUDE OIL ESCAPED THROUGH VENTS AND LANDED ON GRAVEL OUTSIDE OF THE BUILDING. ALL CRUDE OIL WAS CLEANED UP AND CONTAMINATED SOIL PROPERLY DISPOSED OF. THE INVESTIGATION DETERMINED THE RELEASE WAS DUE TO HUMAN ERROR FROM THE UNINTENTIONAL LOOSENING OF THE THREADED FITTING.
