Incident Narrative

AT APPROXIMATELY 14:18 ON APRIL 5, 2012, A STAIN WAS DISCOVERED ON THE GROUND NEAR THE EAST SIDE OF TANK 17 AT LIMA SOUTH TERMINAL. THE OSRO WAS CALLED AND INVESTIGATION BEGAN WITH TRENCHING AND POT HOLES. THERE WAS NO MEASURABLE AMOUNT OF FREE PRODUCT TO REPORT. CALCULATIONS BASED ON SOIL SATURATION ESTIMATE THE AMOUNT OF PRODUCT AT LESS THAN 4 GALLONS. THE TANK WAS ISOLATED AND EMPTIED IN ORDER TO CLEAN THE TANK AND PERFORM FURTHER INVESTIGATION IN AN EFFORT TO DETERMINE THE SOURCE OF THE PRODUCT. ALTHOUGH NUMEROUS TESTS HAVE BEEN CONDUCTED ON THE TANK, IT HAS STILL NOT BEEN VERIFIED THAT THE STAINED SOIL RESULTED FROM A LEAK IN THE TANK. EVEN THOUGH THIS INCIDENT DID NOT MEET THE REPORTING CRITERIA, ON MAY 23, 2012 BUCKEYE REPRESENTATIVES DETERMINED THAT THE COSTS MAY EVENTUALLY REACH THE REPORTING THRESHOLD OF $50,000 AND REPORTED THE SITUATION TO THE NRC (CASE #1012393). THE STAINED SOIL HAS BEEN REMOVED AND PROPERLY HANDLED WHILE INVESTIGATION EFFORTS CONTINUE. AT THE TIME OF THIS SUBMISSION, IT HAS STILL NOT BEEN DETERMINED IF THE PRODUCT CAME FROM THE TANK AND NONE OF THE REPORTING CRITERIA HAVE BEEN MET, BUT THIS REPORT HAS BEEN FILED AT THE REQUEST OF PHMSA'S CENTRAL REGION. A FLOOR SCAN WAS COMPLETED ON MAY 9, 2012 AND A VACUUM BOX TEST WAS COMPLETED ON MAY29, 2012 AND NEITHER TEST CONFIRMED A LEAK IN THE TANK BOTTOM. FURTHER INVESTIGATION WAS DONE BY PERFORMING A HELIUM TEST ON JUNE 14, 2012 WHICH FOUND A PINHOLE LEAK IN A FLOOR PLATE. IT APPEARS THAT THE CAUSE IS DUE TO CORROSION. ADDITIONAL INVESTIGATION IS BEING CONDUCTED AT THE TIME OF THE SUBMISSION OF THIS SUPPLEMENTAL REPORT. TANK BOTTOM REPLACEMENT PROJECT UNDERTAKEN COMPLETION DATE APRIL 2013
