ON SEPTEMBER 26, 2013 AT 14:30 A BUCKEYE EMPLOYEE WAS PERFORMING A ROUTINE MONTHLY TANK INSPECTION ON TANK 206 IN MACUNGIE PA. DURING THE INSPECTION THE EMPLOYEE DETECTED HIGH VAPOR ODORS AND RECEIVED HIGH VAPOR READINGS ON THE NORTH, WEST AND EAST SIDES OF THE TANK IN THE INTERSTITIAL SPACE BETWEEN THE TANK BOTTOM AND THE BETONITE LINER. HIGH VAPOR READINGS WE NOT DETECTED IN ANY OF THE MONITORY WELLS IN THE VICINITY OF TANK 206. TRANSFER OF TANK CONTENTS (4500 BBS OF GASOLINE) WAS IMMEDIATELY UNDERTAKEN AND TANK 206 REMOVED FROM SERVICE. IT WAS DISCOVERED THAT APPROXIMATELY 3.7 BBLS OF GASOLINE HAD BEEN RELEASED FROM THE TANK BOTTOM. ALL FREE PRODUCT WAS CAPTURED IN THE INTERSTITIAL SPACE BETWEEN THE TANK BOTTOM AND THE BETONITE LINER. THE BETONITE LINER PREVENTED PRODUCT FROM REACHING THE SOIL AND NO PRODUCT WAS DETECTED IN ANY OF THE MONITORING WELLS IN THE FACINITY OF TANK 206. TESTING OF THE TANK BOTTOM TO DETERMINE THE CAUSE AND LOCATION OF THE RELEASE IS ONGOING. BUCKEYE'S INTERNAL INVESTIGATION CONCLUDED THAT THE LEAK PATH APPEARS TO HAVE BEEN CAUSED BY POROSITY IN THE FILLET WELD AT A START/STOP LOCATION IN ONE OF THE FLOOR PLATE WELDS FROM ORIGINAL CONSTRUCTION. THE ENTRAPPED SLAG AND/OR DEBRIS LOOSENED OVER THE YEARS ALLOWING FOR A VERY SMALL LEAK PATH.
