Incident Narrative

AT APPROXIMATELY 0744 ON 11/12/2014, KM'S BARSTOW LINE RIDER ARRIVED AT THE BAKER PUMP STATION TO PERFORM A WEEKLY REMOTE FACILITY INSPECTION. UPON ARRIVAL, HE OBSERVED STANDING JET FUEL IN THE CONTAINMENT PAD AND SOME STAINING IN THE DIRT AROUND BAKER 8-INCH MAINLINE PUMPING UNIT #4. THE LINE RIDER IMMEDIATELY CONTACTED THE CONTROLLER TO REPORT HIS FINDING. ALL AGENCY NOTIFICATIONS WERE CONDUCTED. AFTER INVESTIGATION, IT WAS DETERMINED THAT THE RELEASE ORIGINATED FROM A FAILED TUBING FITTING. 8.7 GALLONS OF JET FUEL WERE KEPT INSIDE CONTAINMENT AND 4.3 GALLONS WERE ESTIMATED TO HAVE CAUSED THE STAIN OUTSIDE OF CONTAINMENT FOR A TOTAL RELEASE VOLUME OF 13 GALLONS. NOTE: PART G, NO. 6 THE FITTING WAS SENT TO THE MANUFACTURER FOR ANALYSIS. THIS REPORT WILL BE SUPPLEMENTED WHEN THE RESULTS ARE DETERMINED. NOTE 2: PART G, NO. 6 (SUPPLEMENTAL UPDATE): A THIRD PARTY ENGINEERING FIRM PERFORMED A VISUAL AND MICROSCOPIC EXAMINATION AND FOUND A SLIGHT AMOUNT OF VISIBLE WEAR AND INTERNAL DAMAGE OR DEFORMATION AT THE FRONT END OF THE FERRULE THIS AREA NORMALLY SEATS AGAINST A THREADED FITTING TO MAKE A COMPLETE SEAL AROUND THE TUBING. THE FIRM IS UNABLE TO CONCLUSIVELY IDENTIFY THE CAUSE OF FAILURE. THEY STATED, ""IT IS POSSIBLE THAT THE WEAR IS DUE TO THE TIGHTENING THE FITTING TO THE TUBING OR, ALTERNATIVELY, IT COULD HAVE HAPPENED SOMETIME AFTER INSTALLATION"".
