LOCAL OPERATIONS RECEIVED A CALL FROM A PRODUCTION COMPANY OF A POSSIBLE RELEASE OF CRUDE FROM A CONNECTION POINT. UPON ARRIVAL AT THE SCENE A PINHOLE LEAK AT THE 6:00 POSITION WAS FOUND IN ABOVE GROUND PIPING. UPDATE REQUESTED FROM ACCIDENT TEAM: D-2: 48 ROLL OFF BINS OF IMPACTED SOIL WERE SENT TO BE REMEDIATED AND THE REMOVED SOIL AREA WAS REPLACED WITH ROAD BASE. E-6&9: THE LEAK RATE WAS BELIEVED TO BE IN THE 1.5 TO 2 BPH LEAK RANGE. AVERAGE FLOW RATE ON THIS NC15 SYSTEM WAS APPROXIMATELY 1100 BPH FOR MOST OF JANUARY. THE LEAK RATE WAS <0.2% OF FLOW. CPM LEAK DETECTION SYSTEMS LIKE OUR PLM SYSTEM TYPICALLY AREN'T EFFECTIVE FOR IDENTIFYING SMALL LEAKS BELOW 0.5% (DUE TO EQUIPMENT ACCURACIES AND OPERATIONAL CONSIDERATIONS). THE CONTROLLER DID NOT RECEIVE ANY ALARMS RELATED TO THIS EVENT FROM PLM OR OTHERWISE. G1-8: THE CSFM PERFORMED A FIELD EXAMINATION AND INSTRUCTED US THERE WAS NO NEED FOR A METALLURGICAL ANALYSIS.

THIS AREA WAS AN UNDERUTILIZED PORTION OF MANIFOLD PIPING THAT HAD NOT SEEN ANY FLOW FOR A LONG PERIOD OF TIME IS WHAT IS BELIEVED TO HAVE CAUSED THIS INCIDENT.
