Incident Narrative

WHILE PERFORMING LINE FILL ACTIVITIES TO COMMISSION NEW CONSTRUCTION AT THE FACILITY, AN INSPECTOR OBSERVED CRUDE OIL ON THE GROUND IN THE MANIFOLD AREA. LOCAL OPERATIONS PERSONNEL CLOSED ISOLATION VALVES AND ISOLATED THE RELEASE AREA FROM FACILITY OPERATIONS. EMERGENCY RESPONSE PROCEDURES WERE IMPLEMENTED. THE RELEASE WAS LOCATED WITHIN A CONTAINED DIKE AREA. VACUUM TRUCKS WERE USED TO CONTAIN THE FREE PRODUCT AND IMPACTED SOIL WAS EXCAVATED, CONTAINERIZED, AND PROPERLY DISPOSED. THE RELEASE ORIGINATED FROM A CRACK IN THE GIRTH WELD LOCATED NEAR THE SOIL/AIR TRANSITION AREA. THE DEFECTIVE PIPE SECTION WAS REMOVED AND REPLACED WITH PRETESTED PIPE. . THE DEFECTIVE SECTION WAS SENT IN FOR METALLURGICAL ANALYSIS. THE ANALYSIS INDICATES THE FAILURE WAS LIKELY THE RESULT OF ABOVE GROUND PIPE MOVEMENT DURING CONSTRUCTION ACTIVITIES CAUSING A DUCTILE CRACK TO FORM. THE GIRTH WELD CRACK ORIGINATED IN AN AREA OF THE WELD WHERE THE CONNECTOR PIPE WAS NOT FUSED TO THE ELBOW GIRTH WELD. GIRTH WELDS AT TWO OTHER HEADERS AT THIS FACILITY WERE EXAMINED AND TWO SECTIONS WERE REPLACED WITH NEW PRETESTED SPOOL PIECES.
