Incident Narrative

AT 3:50 PM ON FEBRUARY 28, 2013, THE STATION OPERATOR DISCOVERED THE LEAK. THE STATION OPERATOR IMMEDIATELY NOTIFIED THE CONTROLLER TO SHUT DOWN THE SCHURR STATION DELIVERY TO CHASE LINE SEGMENT AND PERFORMED NOTIFICATION TO INITIATE THE EMERGENCY RESPONSE PLAN. THE EMERGENCY RESPONSE TEAM RESPONDED AND SECURED THE RELEASE ON FEBRUARY 28, 2013 AND RETURN THE NEXT DAY AND PERFORMED THE MAJORITY OF THE CLEAN-UP WORK. APPROXIMATELY 6 YARDS OF SOIL WERE EXCAVATED. THE LEAK CAUSE WAS DETERMINED TO BE AN O-RING FAILURE ON THE CHASE STATION P-2 PUMP SUCTION VALVE. THE VALVE WAS REPAIRED ON FEBRUARY 28, 2013 AND THE PIPELINE WAS RESTARTED AT 5:05 PM. THE CAUSAL FACTORS WERE, 1) VALVE WAS NOT REPAIRED UPON DISCOVERY THAT OIL WAS SEEPING FROM THE GLAND VENT AND, 2) THE GLAND VENT PLUG WAS IN THE OPEN POSITION. ROOT CAUSES WERE, 1) VALVE INSPECTION PROCEDURE DID NOT ADDRESS THE STEM GLAND CAVITY VENT, 2) PRE-JOB BRIEFING NEEDS IMPROVEMENT, AND 3) TASK NOT ANALYZED. CORRECTIVE ACTIONS INCLUDE, 1) REFRESH EMPLOYEE TRAINING AND INFORMATION REGARDING BLOCK VALVE INSPECTION, AND 2) EVALUATED SIMILAR VALVES AND ASSURE GLAND VENT PLUGS ARE POSITIONED CORRECTLY.
