Incident Narrative

ON FRIDAY EVENING JUNE 16 ABOUT 5PM THE STATION FIRE-EYE TRIPPED THE OGALLAH PUMP STATION FACILITY ESD, SHUTTING DOWN THE PUMP AND BLOCKING IN THE STATION. PIPELINE CONTROL COULD NOT GET THE REMOTE CAMERAS TO PULL UP TO VERIFY PRESENCE OF ACTUAL FIRE, AND OUR TECHNICIAN RESPONDED IN PERSON WITHIN ABOUT 20 MINUTES, TO AN OBVIOUS FIRE. THE FIRE WAS LOCALIZED TO ONE OF THE TWO PUMPS, P-200. THE FIRE DEPARTMENT RESPONDED AND OUR TECHNICIAN AND THE FIRE DEPARTMENT STOOD BY ABOUT 3/4 MILE AWAY FROM THE STATION. OGALLAH PS IS ON A DEAD END SO THERE WAS NO CONCERN OF PUBLIC ENCROACHMENT. THE FIRE SIZE WAS INITIALLY AROUND 3 TO 4 FEET HIGH AND GRADUALLY DECREASING OVER TIME. DECISION WAS MADE TO ALLOW FOR FIRE TO CONSUME LEAKING PRODUCT UNTIL SIZE WAS DECREASED TO REASONABLE SIZE FOR ENTRY WITH A DEVELOPED SAFE WORK MANAGEMENT WORK PLAN. ENTRY TO THE SITE OCCURRED ON SATURDAY EVENING TO IGNITE THE FACILITY FLARE AND OPEN MANUAL BLOWDOWNS TO ACCELERATE THE DEPRESSURIZATION. ONCE THE MANUAL BLOWDOWN VALVES WERE OPENED, THE SEAL FIRE SOON EXTINGUISHED BY ABOUT 7PM. THE SITE WAS INSPECTED AND UTILITY POWER WAS RESTORED BEFORE THE UPS BATTERIES EXPIRED. NO DELIVERY VOLUMES WERE IMPACTED DURING FIRE EVENT DUE TO THE PUMP STATION BEING ISOLATED FROM MAINLINE AND FIRE SUFFICIENTLY AWAY FROM THE MAINLINE. OGALLAH STATION SECOND PUMP, P-100 WAS PUT BACK INTO SERVICE AS OF 6/20/23 18:48 LOCAL TIME. PUMP P-200, ONE THAT CAUGHT FIRE, IS STILL OUT OF SERVICE.
