Incident Narrative

ON 10/22 AT APPROXIMATELY 0725 THE COLTON NORTH OPERATOR ON DUTY DISCOVERED PRODUCT LEAKING FROM THE CN-111 PIT VALVE MOV IN A 5' DEEP VAULT WITH A GRAVEL BOTTOM. THIS VALVE ISOLATES JET FUEL DELIVERY TO COLTON NORTH TANK 111. THE WA-CL 16"" PIPELINE WAS IMMEDIATELY SHUT DOWN WHICH SLOWED THE RELEASE WHICH ALLOWED LOCAL PERSONNEL TO FURTHER SEAT THE VALVE, COMPLETELY STOPPING THE RELEASE. A DRIP PAN PLACED UNDER THE VALVE CAPTURED APPROXIMATELY 15 GALLONS OF PRODUCT PRIOR TO THE RELEASE BEING STOPPED. THE LINE WAS DRAINED DOWN AND THE VALVE WAS REPLACED. REMEDIATION IS STILL INVESTIGATING THE EXTENT OF THE SPILL BELOW THE SURFACE. NOTIFICATIONS WERE MADE TO CALIFORNIA OES ON 10/22 AT 07:54, HOWEVER THE REPORT TO THE NRC WAS MADE ON 11/1 PURSUANT TO 49 CFR 195.52 (A)(3) DUE TO ANTICIPATED COSTS EXCEEDING $50,000, WHICH HAD NOT BEEN PREVIOUSLY EXPECTED. THE 48 HOUR UPDATE WAS MADE ON 11/3 PER 49 CFR 195.52 (D). THIS SUPPLEMENTAL/FINAL REPORT IS BEING SUBMITTED AS A RESULT OF COMPLETING THE INVESTIGATION OF THE CAUSE OF THE RELEASE AND KNOWING THE FINAL COSTS ASSOCIATED WITH REMEDIATION OF THE SPILL. THE APPARENT CAUSE WAS IDENTIFIED AS DEFECTIVE EQUIPMENT DUE TO A DESIGN FLAW OF THE VALVE WHICH WAS THE VALVE STEM NOT BEING ENGINEERED WITH A WEEP HOLE FOR ACCUMULATED MOISTURE TO DRAIN FROM, CAUSING CORROSION OF THE VALVE STEM AND SUBSEQUENT O-RING FAILURE.
