ALL INTERNAL AND EXTERNAL NOTIFICATIONS WERE COMPLETED AND EMERGENCY RESPONSE PROCEDURES WERE INITIATED AS A POTENTIAL RELEASE. THE PIPELINE WAS NOT IN OPERATION AT THE TIME OF DISCOVERY, AS A PRECAUTION, THE CONTROL CENTER LOWERED THE PRESSURE ON THE PIPELINE AND MAINLINE VALVES WERE CLOSED UP AND DOWNSTREAM OF THE EXCAVATION FOR FURTHER INVESTIGATION. BUCKEYE PERSONNEL CONTINUED TO EXCAVATE THE AREA UNTIL THE AFFECTED SOIL WAS REMOVED FROM THE AREA AND THE PIPE WAS FULLY EXPOSED. PHASED ARRAY UT EVALUATION DETERMINED THE SOURCE WAS A PINHOLE LOCATED AT THE SAME LOCATION OF THE SUSPECTED ANOMALY CALLED BY THE ILI TOOL.
