Incident Narrative

ON APRIL 26, 2015, AT APPROXIMATELY 19:55 EST, THE CONTROL CENTER CONTACTED THE LOCAL OPERATIONS MANAGER TO NOTIFY HIM OF THE JAMES CITY FIRE DEPARTMENT'S (JCFD) ARRIVAL AT YORKTOWN STATION. A HOMEOWNER ACROSS THE STREET FROM YORKTOWN STATION CALLED 911 AFTER SEEING A MISTY CLOUD ARISE FROM AROUND UNIT 2. A TECHNICIAN WAS EARLIER DISPATCHED TO INVESTIGATE A SEPARATE ALARM AT THE FACILITY. THE JCFD ARRIVED FIVE MINUTES AFTER OUR TECHNICIAN WAS AT THE FACILITY. UPON ARRIVAL TO YORKTOWN, THE TECHNICIAN FOUND A FINE MISTY VAPOR OF DIESEL COMING FROM THE PUMP SEAL HOUSING AND PRODUCT ON THE GROUND AROUND THE BASE OF UNIT 2. PUMP UNIT 2 WAS IMMEDIATELY SHUT DOWN AFTER TECHNICIAN INFORMED CONTROL CENTER OF THE SITUATION. INITIAL INVESTIGATION FOUND A CRACK IN A 1/2"" TUBING ABOVE THE FERRULE ON THE DISCHARGE SIDE OF PUMP - THIS IS THE TUBING LINE THAT SENDS PRODUCT FROM THE DISCHARGE SIDE OF THE PUMP TO THE OUTBOARD BEARING HOUSING. THE LINE WAS REPLACED WITH CARBON STEEL TUBING. INTERNAL AND STATE NOTIFICATIONS WERE MADE AS WELL AS OSROS CONTACTED AND CLEAN UP ACTIVITY BEGAN IMMEDIATELY. AS OF MAY 1, 2015, CLEAN-UP EFFORTS HAVE RECOVERED APPROXIMATELY 58 GALLONS FROM EXCAVATED SOIL, DIAPERS AND FREE STANDING PRODUCT WAS RECOVERED FROM OPEN EXCAVATION AND TEST WELLS DUG TO ACCUMULATE PRODUCT. MONITORING WILL CONTINUE FOR ANOTHER WEEK. INCIDENT ANALYSIS OF THE EVENT DETERMINED THAT HIGH AND LOW FREQUENCY CYCLES AND MODULATIONS WERE THE CAUSE OF THE FISSURE ALONG THE TUBING. THE INTERIM REPAIR OF THE FLEXIBLE STEEL HOSE WILL BE THE FINAL SOLUTION AS REPLACEMENT FOR THE TUBING.
