Incident Narrative

ON 7/7/2015 A SMALL LEAK OF APPROX. 3 GALLONS WAS FOUND CLOSE TO TANK 80-11. THE TANK WAS STRIPPED AND ALL LINES ASSOCIATED WITH THE TANK WERE SHUTDOWN IMMEDIATELY. TEST WELLS WERE INSTALLED AROUND THE TANK TO DETERMINE IF THE LEAK WAS COMING FROM THE PIPING OR TANK. THE WELLS WERE MONITORED FOR 3 WEEKS AND REMAINED EMPTY. ON 7/30/2015 THE DECISION WAS MADE TO GO INTO THE TANK TO INVESTIGATE IF THE PRODUCT CAME FROM THE TANK. THE LINER WAS REMOVED AND THE FLOOR HAS BEEN SCANNED. AT THE TIME OF THE DECISION TO GO INTO THE TANK THE NRC WAS NOTIFIED AS THE COST WAS GOING TO EXCEED $50,000. REPAIRS ARE COMPLETED. API 653 INSPECTION INDICATED A LINEAR INDICATION WHERE LOCALIZED PITTING OCCURRED IN THE HEAT AFFECTED ZONE OF A CORNER WELD. THE PLATE WAS REPAIRED AND THE TANK BOTTOM WAS VACUUM BOX TESTED TO INSPECT THE INTEGRITY OF THE SHELL TO BOTTOM INTERFACE. PLAN TO PREVENT REOCCURRENCE: WE PERFORM VACUUM BOX TESTING ON ALL TANK BOTTOMS, TO INCLUDE CORNER WELD FOR ALL UNCOATED TANK BOTTOMS. WE WILL BE PERFORMING ALTERNATING CURRENT FIELD MEASUREMENT (ACFM) ON ALL COATED CORNER WELDS ON ALL COATED TANK BOTTOMS. WE DO THIS TO IDENTIFY ANY LINEAR INDICATIONS.
