Incident Narrative

ON 01/04/2023 AT 1000, WHILE DRAINING DOWN THE MIDWAY FILTER VESSELS IN PREPARATION FOR AN ELEMENT CHANGEOUT, THE OPERATORS PERFORMING THE WORK WERE RE-ASSIGNED FOR A TEMPORARY, PRIORITY TASK. WHEN THE OPERATORS LEFT THE AREA, THEY SHUT DOWN THE SUMP PUMP, BUT DID NOT CLOSE THE BALL VALVE ISOLATING THE OUTBOUND PRODUCT LINE FROM THE SUMP SEPARATOR TO THE JET FUEL SYSTEM. THE OPERATORS MOBILIZED TO THE NEWLY ASSIGNED TASK, PERFORMED THE WORK, THEN RETURNED TO THE ORIGINAL FILTER VESSEL CHANGEOUT TASK. UPON ARRIVAL AT 1420, THEY DISCOVERED PRODUCT IN THE SECONDARY CONTAINMENT BELOW THE MIDWAY FILTERS. THE 50-GALLON SUMP SEPARATOR VESSEL HAD BACKFILLED THROUGH A FAILED CHECK VALVE ON THE DISCHARGE OF THE SUMP PUMP ALLOWING APPROXIMATELY 26 BBLS OF JET-A TO BE RELEASED INTO SECONDARY, CONCRETE CONTAINMENT. THE FILTER AREA WAS ISOLATED AT 1421. THE SUPERVISOR WAS IMMEDIATELY NOTIFIED, AND RELEASE RECOVERY WAS INITIATED. ALL RELEASED PRODUCT WAS COLLECTED AND OFFLOADED INTO THE TRANSMIX SYSTEM. ON 01/05/2023 AT 1100 ARGO MAINTENANCE REMOVED AND REPLACED THE FAULTY CHECK VALVE AND INSTALLED NEW BALL VALVE WITH LOCKING HANDLE. THE EQUIPMENT WAS PLACED BACK IN SERVICE ON 01/05/2023 AT 1200. PRESSURE LISTED IN E1 IS AN ESTIMATE (BASED ON TANK HEAD PRESSURE). THE TIME SPECIFIED IN PART A4 WAS ESTIMATED BASED ON THE VOLUME OF PRODUCT RECOVERED, THE VOLUME OF THE SUMP, PLUS THE 5 GALLONS REQUIRED TO EXCEED THE REPORTABLE QUANTITY THRESHOLD.
