Incident Narrative
SYSTEM RELIEVED INTO AND OVERFLOWED THE STATION SUMP DURING NORMAL OPERATION DUE TO THE IMPROPER SPECIFICATION AND INSTALLATION OF THE THERMAL RELIEF VALVE INSTALLED DURING INITIAL CONSTRUCTION. CONSEQUENTLY, THE THERMAL RELIEF SYSTEM ACTIVATED AT 285PSI, WITH A HIGH OBSERVED PRESSURE OF 444PSI, WELL BELOW THE SYSTEM MOP OF 1480PSI AND FILLED THE STATION SUMP FROM A LOW PRESSURE SURGE. THE STATION SUMP OVERFLOWED IN SPITE OF THE SYSTEM BEING SHUT-DOWN AFTER THE SUMP HIGH LEVEL ALARMS ACTIVATED. AT NO TIME DURING THIS DID THE PIPELINE EXCEED ITS MOP. THE CORRECT THERMAL RELIEF VALVES HAVE BEEN INSTALLED WITH THE PROPER RELIEF SET POINTS TO ALLOW FOR CONTINUED NORMAL OPERATIONS.
