|Barge Loading of Coke (EQT#030, EIQ#8-00)||Cause: During the loading of the barge, the coke pile became too large and overflowed the lip of the barge in to the Mississippi River.|
Notes: Boom was deployed to prevent the coke from floating downriver. Attempts to recover the petroleum coke were made using a vacuum truck and skimmers. An incident investigation was initiated on 10/08/13 and is currently in progress. There is no reportable quantities for petroleum coke, but the spill violated state environmental regulatory code LAC 33:111.1305.
|Conveyor (EQT 028)||Cause: Malfunction at Marathon's coke belt. The conveyor belt split and the belt was patched with clips. Because of the clips, the scrapers which remove coke from the belt could not be reinstalled. After the repair, the belt was restarted, which caused the fines to enter the Mississippi River. There were no known offsite impacts.|
Notes: No remedial actions taken. The petroleum coke fines dispersed immediately upon entering the water. Refinery letter indicates that an investigation was in progress as of 5/4/2014.
