Incident Narrative
"ON SEPTEMBER 11, 2018 AT 1:44 PM CDT, THE EDMONTON CONTROL CENTER RECEIVED A WARNING LEL ALARM ON LINE 5 AT RAPID RIVER STATION. THE STATION TECHNICIAN WAS CALLED OUT TO INVESTIGATE THE ALARM AND DISCOVERED A CRUDE OIL RELEASE FROM THE LINE 5 UNIT 2 DISCHARGE VALVE. THE VALVE WAS IN THE CLOSED POSITION; HOWEVER, IT IS UNKNOWN WHETHER THE SEATS WERE HOLDING AT THE TIME SO THE STATION WAS ISOLATED UNTIL FURTHER INVESTIGATION COULD TAKE PLACE. LINE 5 REMAINED RUNNING DURING THE BYPASS. APPROXIMATELY 10 GALLONS OF CRUDE OIL WAS RELEASED AND REMAINED WITHIN THE IMMEDIATE AREA OF THE VALVE. APPROXIMATELY 1.6 CUBIC YARDS OF CONTAMINATED SOIL WAS REMOVED FROM RELEASE SITE. THE CAUSE OF THE RELEASE WAS DUE TO NORMAL WEAR AND TEAR OF THE O-RING. OPERATIONS AND PLM BLED OFF NGL PRESSURE FROM THE HEADER, ISOLATED THE UNIT AND CONNECTED A HOSE FROM THE VALVE BODY TO THE SUMP AFTER CONFIRMING THE GATE WAS HOLDING AS A PRECAUTION. THE STATION RESUMED NORMAL OPERATION WITH UNIT 2 ISOLATED. THE O-RING WILL BE REPLACED IN DECEMBER 2018 DURING A SCHEDULED OUTAGE AT RAPID RIVER STATION."
