Cause detail: AT APPROXIMATELY 2240 (10:40 PM LOCAL TIME) ON JUNE 5, 2012, THE CONTROL CENTER RECEIVED A PUMP SEAL FAILURE ALARM AT BAKER BOOSTER STATION AND PUMP #4 SHUTDOWN AUTOMATICALLY. THE ALARM CLEARED, THERE WERE NO OTHER ALARMS (NO SUMP ALARM), AND PRESSURES WERE NORMAL INDICATING EITHER A SMALL AMOUNT OF PRODUCT STAYING WITHIN THE CLOSED SYSTEM OR A FALSE ALARM. AFTER RESTARTING, A DECISION WAS MADE BY FIELD MANAGEMENT TO SHUTDOWN THE SYSTEM AND DISPATCH A TECHNICIAN TO THE PUMP STATION. WHILE IN THE PROCESS OF SHUTTING DOWN THE UNIT THE CONTROLLER RECEIVED A HIGH SUMP ALARM. THE CONTROLLER THEN ISOLATED THE PUMP AND STATION BY CLOSING APPROPRIATE VALVES. AT APPROXIMATELY 0031 AFTER TURNING ON STATION LIGHTING, THE TECHNICIAN IDENTIFIED TWO STAINS ON THE GROUND WITH DIMENSIONS 4 FT. X 13 FT. AND 5 FT. X 3 FT. LATER INVESTIGATION DETERMINED THE CAUSE OF THE RELEASE AS FAILURE (ATYPICAL ' FAILED WITHIN 6 MONTHS OF INSTALLATION) OF THE INBOARD PUMP SEAL. THE TECHNICIAN AND CONTRACTOR SUPPORT TEAM REPLACED THE SEAL ON 6/11/12. APPROXIMATELY 17.6 GALLONS (0.42 BBLS) OF TURBINE FUEL WAS RELEASED AND THE CONTAMINATED SOIL* AND PRODUCT WAS PROPERLY REMOVED FROM THE SITE. * AFTER REMOVING THE 'WET' CONTAMINATED SOIL, ADDITIONAL CONTAMINATED SOIL WAS DISCOVERED.
