Incident Narrative

AT APPROXIMATELY 10:45 AM PST, AN OPERATOR AT EMIDIO STATION DISCOVERED A LEAK EMANATING FROM A TANK MIXER FROM TANK 3000X 08. THE TANK MIXER WAS IMMEDIATELY SHUTDOWN AND THE LEAK STOPPED. BEFORE THE LEAK WAS STOPPED, APPROXIMATELY 3.19 BARRELS OF CRUDE OIL LEAKED THROUGH THE MIXER SEAL AND OVERFILLED A CATCH PAN THAT WAS EVENTUALLY CONTAINED IN THE ASPHALT LINED SECONDARY CONTAINMENT FOR THE TANK. THE RECOVERY OF 3,0 BARRELS AND SOIL CLEAN-UP WAS COMPLETED THE SAME DAY. THE TANK MIXER SEAL WAS REPLACED AND THE MIXER WAS RETURNED TO SERVICE. A FAILURE ANALYSIS WILL BE CONDUCTED ON THE SEAL AND THE RESULTS WILL BE PROVIDED IN A SUPPLEMENTAL REPORT AND THEN SHARED WITH OPERATIONS AND ENGINEERING SUPPLEMENTAL REPORT: PBF/TORRANCE LOGISTIC COMPANY (TLC) SENT THE TANK MIXER MOTOR OUT TO A SPECIALTY SHOP FOR FAILURE ANALYSIS. IT WAS DETERMINED THAT THE PRIMARY AND MATING RING HAD EXCESSIVE WEAR DUE TO LACK OF LUBRICATION THAT COULD BE CAUSED BY AGE. THE SPECIALIST RECOMMENDS EITHER UPGRADING THE PRIMARY AND STATOR RINGS ON THE EXISTING MOTORS OR INSTALLING UPDATING MOTORS AND FOLLOW SCHEDULED MAINTENANCE SUGGESTED BY THE MANUFACTURER. THE TLC TANK DEPARTMENT WILL BE TAKING TANK 3000X08 OUT OF SERVICE IN AUGUST 2019 FOR SCHEDULED 653 INSPECTION AT WHICH TIME THEY WILL DECIDE WHETHER TO REBUILD THE MOTORS WITH THE RECOMMEND RINGS OR REPLACE WITH NEW MIXERS. IN THE MEANTIME THE EXISTING MOTOR'S SEAL WAS REPLACE AND THE MIXER WAS PUT BACK INTO SERVICE WITH DAILY SURVEILLANCE IMPOSED UNTIL THE 653 INSPECTION IS PERFORMED.
