Incident Narrative

ON MONDAY APRIL 1, 2013 AT APPROXIMATELY 17:25 A 3RD PARTY REPORTED TO LOCAL MAINTENANCE THAT AN ODOR AND DEAD VEGETATION WERE DETECTED IN AN INACTIVE FARM FIELD IN TEMPERANCE MI. LOCAL BUCKEYE MAINTENANCE PERSONNEL WERE IMMEDIATELY DISPATCHED TO INVESTIGATE THE REPORT AND THE THREE PIPELINES IN THE AREA WERE SHUT DOWN AND STATIC PRESSURES MONITORED BY THE CONTROL CENTER. UPON CONFIRMATION OF THE RELEASE, ALL PROCEDURAL AND REQUIRED NOTIFICATIONS WERE MADE. EXCAVATION EFFORTS LOCATED THE SOURCE OF THE RELEASE AND A TEMPORARY B-SLEEVE WAS INSTALLED. DURING PRESSURE TESTING AN ADDITIONAL RELEASE ON THE SAME PIPE JOINT WAS DISCOVERED. PERMANENT REPAIRS WERE MADE THAT INCLUDED THE CUT OUT AND INSTALLATION OF A 97' FOOT SECTION OF PIPE. TOTAL RELEASE VOLUME IS ESTIMATED AT 2.39 BBLS OF JET FUEL. REMEDIATION EFFORTS ARE ONGOING AT THIS TIME, PENDING THE RESULT OF SOIL ANALYSIS. METALLURGICAL ANALYSIS IS BEING CONDUCTED BY A THIRD PARTY LABORATORY. UPDATE 08/15/2013 AN OXIDE EMBEDDED DEFECT IN THE LONG SEAM WELD WAS DETECTED AS BY RESULT OF METALLURGICAL ANALYSIS. THE THROUGH-WALL DEFECT AT THE FIRST LEAK LOCATION WAS APPROXIMATELY 1/2 LONG ON THE OD, AND APPEARED AS AN AXIALLY ALIGNED CRACK-LIKE DEFECT. WELD DEFECTS OF THIS TYPE MAY SURVIVE AND HYDROTESTS FOR SEVERAL YEARS OR DECADES BEFORE STRESSES OR CYCLIC STRESSES WORK THE OXIDES FREE AND THEY LEAD TO A LEAK. THE SECOND LEAK LOCATION COULD NOT BE LOCATED DURING LABORATORY ANALYSIS AND NO FURTHER THROUGH WALL DEFECTS WERE IDENTIFIED DURING THE ANALYSIS UPDATE 8/18/2016 THE REMEDIATION OF THE AFFECTED AREA RESULTED IN APPROXIMATELY 1,575 TONS OF SOIL REMOVED FOR REMEDIATION, OF WHICH, AN ESTIMATED 275 TONS WERE DETERMINED TO BE CONTAMINATED. THE DEPTH OF COVER AT THE AFFECTED LOCATION WAS 66 INCHES.
