Incident Narrative
WHILE ESTABLISHING FLOW FROM A CUSTOMER'S INBOUND LINE SEGMENT TO A DOWNSTREAM CUSTOMER'S FACILITY, PIPING INSIDE THE OPERATOR'S FACILITY WAS OVER-PRESSURED FOR A BRIEF PERIOD OF TIME BEFORE THE OPERATOR'S SHUT DOWN VALVE (SDV) CLOSED COMPLETELY. A SMALL THERMAL RELIEF VALVE ON THE OPERATOR'S FACILITY OPENED AT SET POINT DURING THIS TIME FRAME AND RELEASED AN ESTIMATED 7.3 GALLONS OF PROPANE TO THE ATMOSPHERE. PER THE OPERATOR'S INCIDENT INVESTIGATION, IT APPEARS THAT THE DOWNSTREAM CUSTOMER INFORMED THE OPERATOR THAT THE DOWNSTREAM CUSTOMER WAS READY TO RECEIVE PRODUCT WHEN, IN FACT, A VALVE IN THE FLOW PATH INSIDE THE DOWNSTREAM CUSTOMER'S FACILITY WAS NOT OPEN WHEN THE OPERATOR INITIATED FLOW FROM THE INBOUND LINE SEGMENT. THE OPERATOR'S SDV SETPOINT HAS BEEN LOWERED TO PREVENT THE THERMAL RELIEF VALVE FROM RELIEVING DURING A SURGE CONDITION.
