Incident Narrative

MAGELLAN'S OPERATIONS CONTROL RECEIVED A CALL FROM THE LOCAL FIRE DEPARTMENT AT 05:25 ON 2/18/18 REPORTING A TANK FIRE AT THE FARGO TERMINAL. ALL ASSOCIATED PIPELINE OPERATIONS WERE SHUT DOWN, ISOLATED AND CODE RED RESPONSE PROTOCOLS WERE INITIATED. MAGELLAN, LOCAL FIRE, POLICE, AND CONTRACT RESOURCES RESPONDED TO THE INCIDENT. PORTIONS OF MAIN AVE/HIGHWAY 10 (SOUTHERN FACILITY BORDER) WERE CLOSED BY LAW ENFORCEMENT AND BNSF RAILROAD TRAFFIC (NORTHERN FACILITY BORDER) WAS SUSPENDED. THE CITY OF WEST FARGO ISSUED A SHELTER IN PLACE ALERT TO THE PUBLIC WITHIN A 5-MILE RADIUS VIA THEIR PUBLIC ALERT SYSTEM. LOCAL FIRE DEPARTMENT PERSONNEL EXTINGUISHED THE FIRE AT 11:57 WITH WATER AND FOAM SUPPRESSANT AND CONTINUED TO COOL THE AFFECTED COMPONENTS FOR THE NEXT HOUR. THE SUBJECT TANK VALVE WAS CLOSED AT APPROXIMATELY 14:00 THAT AFTERNOON WHICH STOPPED THE LEAK. RECOVERY OPERATIONS OF IMPACTED WATER AND FREE PRODUCT COMMENCED THEREAFTER. THE FIRE WAS FOUND TO HAVE ORIGINATED FROM THE TANK #4009 TANK PUMP MECHANICAL SEAL. THE TANK PUMP WAS SUPPLYING A MAINLINE OUTBOUND MOVEMENT AT THE TIME OF THE RELEASE. A REVIEW OF OPERATING DATA INDICATES THE RELEASE LIKELY BEGAN AT 02:00. THE TANK PUMP WAS INSTALLED AT TANK 4009 IN 2003 BUT WAS PREVIOUSLY IN-SERVICE AND ORIGINALLY MANUFACTURED IN 1964. THE PUMP HAS BEEN SENT FOR TEARDOWN AND FAILURE ANALYSIS. EACH OF THE REMAINING TANK PUMPS AT FARGO WERE INSPECTED BEFORE RETURNING TO SERVICE. APPROXIMATELY 110 CUBIC YARDS OF SOIL WERE REMEDIATED FAILURE ANALYSIS ON THE PUMP DETERMINED THAT RADIAL BEARING FAILURE WAS THE CAUSE OF THIS INCIDENT.
