Incident Narrative
"WOLVERINE RECEIVED A CALL FROM A LANDOWNER INDICATING ODORS AND SHEEN IN BAUER DRAIN. WOLVERINE INITIALLY RESPONDED, LATER NOTIFYING MARATHON PETROLEUM COMPANY. IT WAS DETERMINED THAT THE RELEASE WAS FROM A MARATHON PETROLEUM COMPANY TANK LINE, OPERATED BY WOLVERINE. INITIAL NRC CALL WAS MADE BY WOLVERINE. SUPPLEMENTAL NRC REPORTS WERE MADE BY MARATHON PIPE LINE. A GASKET FAILURE ON THE TANK LINE WAS INITIALLY IDENTIFIED AS THE LEAK SOURCE. AFTER THE COMPLETION OF THE INVESTIGATION IT WAS DETERMINED THAT THE GASKET FAILED DUE TO MISALIGNMENT DURING CONSTRUCTION. THE AMOUNT RELEASED WAS CALCULATED BASED ON FIELD INVESTIGATION DATA. BOOM WAS INITIALLY PLACED IN BAUER DRAIN AND RECOVERY WELLS INSTALLED TO COLLECT FREE PRODUCT. MPL HAS REMOVED 4,500 TONS OF NON-HAZARDOUS IMPACTED SOILS FROM THIS SITE. THIS IS AN ON-GOING REMEDIATION EFFORT AND THE REPORT INCLUDES THE ESTIMATED FINAL REMEDIATION COSTS."
