APPROX. 4 SECONDS LATER A HIGH PRESSURE ALARM WAS RECEIVED ON THE ENFIELD STATION DISCHARGE LINE. TWO SECONDS LATER THE NEW HARMONY BOOSTER LINE AUTOMATIC SHUT-DOWN ACTIVATED ON THAT LINE AND APPROX. 16 SECONDS LATER THE CONTROL ROOM OPERATOR SHUT DOWN THE ENFIELD STATION PUMPS MANUALLY. HE IMMEDIATELY AT 14:57 APPROX. INITIATED EMERGENCY RESPONSE NOTIFICATIONS TO LOCAL TECHNICIANS. AT 15:00 APPROX. THE CONTROL ROOM TECHNICIAN MADE INTERNAL EMERGENCY RESPONSE NOTIFICATIONS TO REFINERY AND LOGISTICS PERSONNEL. AT 15:56 APPROX. AIR OPERATIONS WAS INSTRUCTED TO FLY BOTH PIPELINE ROW'S AND ALL CRUDE GATHERING INJECTIONS ON THESE SEGMENTS LOOKING FOR ANY EVIDENCE OF LEAKS. AT 16:23 AN NRC REPORT #1147134 WAS SUBMITTED AND AT 17:11 A SUPPLEMENTAL NRC REPORT #1147137 WAS SUBMITTED UPDATING THE INITIAL REPORT. ALSO IDEM WAS NOTIFIED WITH REPORT #63743. LOCATIONS OF LEAKS WERE FOUND AMOUNTING TO APPROX. 2.4 BARRELS OF CRUDE OIL AT THE METER FOR THE ENFIELD PIPELINE AT SMITH RD. AND GIVENS RD. ON COUNTRYMARK PROPERTY NEAR THE NORTH WEST CORNER OF THE PROPERTY. THIS LEAK DID RUN OFF OF THE PROPERTY INTO A ROAD DITCH THEN .5 BARRELS MADE IT INTO MILL CREEK A SHORT DISTANCE BEFORE COUNTRYMARK PERSONNEL CONTAINED IT WITH BOOMS. ALL OF THE OIL WAS RECOVERED FROM MILL CREEK AND 2.3 BARRELS OF OIL WAS RECOVERED IN THE ENFIELD PIPELINE LEAK RECOVERY EFFORT. THERE WAS A SECOND LEAK WELL TOWARD THE CENTER OF COUNTRYMARK REFINERY PROPERTY ON THE NEW HARMONY BOOSTER METER PIPING IN A BACKPRESSURE CONTROL VALVE. THAT LEAK WAS APPROXIMATELY .6 BARRELS OF CRUDE OIL WHICH WAS ISOLATED AND THEN .6 BARRELS RECOVERED. CLEAN-UP ON BOTH LINES WAS STARTED IMMEDIATELY AND WAS COMPLETED WITHIN THE NEXT 20 HOURS. INITIAL CAUSE WAS SUSPECTED TO HAVE BEEN A VALVE DOWNSTREAM OF THE INCOMING METERING FACILITIES WHICH WAS FOUND TO BE CLOSED AND MAY HAVE CAUSED AN OVERPRESSURE CONDITION TO THESE ASSETS. AFTER ALL LEAKS WERE REPAIRED ON 5/7/16 A COUNTRYMARK LOCAL TECHNICIAN WAS DISPATCHED TO BOTH PUMP STATIONS WHERE HE RECALIBRATED PRESSURE CONTROL DEVICES. AT 08:49 ON 5/7/16 THE NEW HARMONY BOOSTER PIPELINE WAS RESTARTED AND AT 11:35 ON 5/7/16 THE ENFIELD PIPELINE WAS RESTARTED. AN INVESTIGATION IS NOW COMPLETE AND IT IS FOUND THAT VALVE LINE UP WAS INCORRECT WITH A 6"" VALVE LEFT CLOSED DURING A TRANSFER WHICH SHOULD HAVE BEEN OPEN AND A KILL SWITCH WHICH HAD NOT BEEN PROPERLY INSPECTED AND MAINTAINED FAILED. A ROOT CAUSE ANALYSIS ""REASON REPORT"" WAS COMPLETED IN WHICH COUNTRYMARK CONCLUDES THAT THE CAUSE WAS ULTIMATELY THAT NO PROCEDURES EXISTED FOR INSPECTION AND MAINTENANCE OF KILL SWITCHES FOR THE CRUDE GATHERING PIPELINES AND NO WRITTEN PROCEDURES EXISTED FOR OPERATOR PERSONNEL REGARDING THE UNLOADING OF CRUDE BARGES.
