Incident Narrative

DURING TERMINAL CHECKS, A LEAK WAS DISCOVERED ON TANK 388 LATERAL LINE AS IT PASSES THROUGH THE EARTHEN DIKE WALL. PRODUCT TRAVELLED UNDER PIPE RACK INTO FACILITY STORM WATER DRAIN PIPING. LINES WERE ISOLATED, EMPTIED AND BLINDED, AND CLEANUP CREWS MOBILIZED. FACILITY WATER OUTFALLS WERE SHUT IN AND LOCKED OUT TO PREVENT ANY PRODUCT FROM LEAVING THE FACILITY INTO THE WATERWAY. LINED PONDS AND THE LAST THREE STAGES OF THE OIL WATER SEPARATOR WERE BOOMED WHERE VACUUM TRUCKS BEGAN PICKING UP FREE PRODUCT OFF THE OIL WATER SEPARATOR AND STORM DRAIN ACCESS POINTS. ALL DRAINAGE PIPING WAS FLUSHED UNTIL NO PRODUCT WAS OBSERVED AT ACCESS POINTS. THE PIPE WITH THE LEAK FEATURE WAS CUT OUT AND SENT TO A LABORATORY FOR METALLURGICAL ANALYSIS, AND A PIECE OF NEW, PRE-TESTED PIPE WAS INSTALLED. THE LINE WAS RETURNED TO SERVICE ONCE REPAIR WAS COMPLETE. THE METALLURGICAL ANALYSIS INDICATED THE CAUSE OF THE RELEASE TO BE INTERNAL CORROSION ON THE BOTTOM OF THE PIPE. IMPACTED SOIL WAS EXCAVATED AND REPLACED WITH FRESH SOIL. THIS SUPPLEMENTAL-FINAL REPORT WAS FILED TO UPDATE THE CAUSE OF THE RELEASE, ALONG WITH PIPE CHARACTERISTICS AND COST INFORMATION.
