Incident Narrative

ON AUGUST 20, 2023, A CONTROL ROOM VAPOR ALARM SOUNDED AT 0804 FOR THE KMCC KARNES PUMP STATION. THE LOCAL OPERATOR WAS CONTACTED AND DISPATCHED TO THE SITE AND WITNESSED PRODUCT LEAKING FROM A PIN HOLE ON THE SIDE OF A STRAINER POT. THE OPERATOR CLOSED THE VALVE AND LEAK STOPPED. 21.4 BBLS. LEAKED INTO CONTAINMENT AND 2 GALLONS SPRAYED OUTSIDE CONTAINMENT. A VACUUM TRUCK WAS CALLED TO BEGIN CLEAN-UP EFFORTS, WHICH WERE COMPLETED THAT EVENING. ON AUGUST 28, 2023, IT WAS DETERMINED THE COST WOULD EXCEED $50,000. THE NRC WAS CONTACTED AND REPORT 1377471 WAS TAKEN. THE FOLLOWING DAY, AUGUST 29, 2023, A 48-HOUR UPDATE WAS GIVEN TO THE NRC AND REPORT 1377624 WAS TAKEN. ON NOVEMBER 8, 2023, THE INVESTIGATION TO DETERMINE THE CAUSE OF THE RELEASE WAS COMPLETED. THE SOURCE OF THE RELEASE WAS A PINHOLE/CORROSION PIT THAT HAD COMPLETELY PENETRATED THE WALL OF STRAINER POT #502 CAUSED BY CORROSION. THE CORROSION WAS CAUSED BY 1) THE PRESENCE OF CORROSION-CAUSING MECHANISMS (WATER, CHLORIDES, OXYGEN, MICROBIOLOGICALLY INFLUENCED CORROSION, IRON SULFIDE); 2) THE PRESENCE OF DEAD-LEG PIPING; AND 3) THE LACK OF DIRECT CHEMICAL TREATMENT UPSTREAM OF THIS PIPING SECTION. CHANGES HAVE BEEN MADE TO THIS NARRATIVE. THE WRONG DATE WAS INADVERTENTLY ENTERED FOR THE NRC NOTIFICATION. THE WRONG TIME WAS ALSO ENTERED INCORRECTLY IN PART A, QUESTION 21A. BOTH HAVE BEEN CORRECTED.
