Incident Narrative

ON 2/7/19 AT 21:16:38, THE CONTROLLER OBSERVED THE SCADA SCREEN FOR THE CFPL HEMLOCK PUMPING STATION TURN MAGENTA, INDICATING A LOSS OF COMMUNICATIONS. THE LOSS OF COMMUNICATIONS WAS DUE TO A POWER OUTAGE AT THE HEMLOCK PUMPING STATION. THE PUMPING STATION CAME BACK ON AT 21:16:43 AND IMMEDIATELY AFTERWARDS, A HIGH METER PRESSURE ALARM WAS RECEIVED. THEN A RELIEF FLOW ALARM WAS RECEIVED AT 21:17:08. AFTER THE CONTROLLER SHUT DOWN THE UPSTREAM BOOSTERS, HE CALLED A LOCAL FIELD OPERATOR TO INFORM THEM OF THE RELIEF FLOW ALARM AT HEMLOCK STATION. THE LOCAL OPERATOR WAS THEN DISPATCHED TO CHECK OUT THE HEMLOCK PUMPING STATION DUE TO THE RELIEF FLOW ALARM. THE HIGHEST RECORDED PRESSURE WAS 238PSI. UPON THEIR ARRIVAL, THE OPERATOR NOTICED A STRONG ODOR OF JET FUEL AND ONCE INSIDE THE FACILITY, SAW A SPRAY OF JET FUEL COMING FROM THE PIPING NEAR THE STRAINER. THE OPERATOR CALLED THE CONTROL CENTER TO INFORM THEM OF THE RELEASE OF JET FUEL AND TO HAVE THEM ISOLATE THE STRAINERS BY CLOSING THE APPROPRIATE VALVES. THE OSRO WAS DISPATCHED TO THE SCENE AND NOTIFICATIONS WERE MADE. THE NATIONAL RESPONSE CENTER WAS NOTIFIED ON 2/8/2019 AT 13:02 IMMEDIATELY AFTER IT WAS DETERMINED IT WAS HIGHLY PROBABLE THE $50,000 REPORTING CRITERIA WOULD BE EXCEEDED. THE AMOUNT IMPACTING GROUNDWATER IS UNKNOWN AT THIS TIME. THE RELEASE WAS DUE TO A 3/4""X1/2"" HEXAGONAL BUSHING USED TO CONNECT A VALVE TO A THREADED INTEGRALLY REINFORCED OUTLET FITTING. THE BUSHING FRACTURED BY DUCTILE OVERLOAD. THE PIPING SYSTEM WAS NOT DESIGNED TO PROPERLY MITIGATE VIBRATION OF THE SYSTEM. IN ADDITION TO THE 6.9 BARRELS OF LIQUID RECOVERED, ELEVEN (11) ROLL OFFS OF CONTAMINATED SOIL WAS ALSO REMOVED FROM THE RELEASE SITE.
