A catastrophic oil spill oil has caused a huge logjam in Missisippi river traffic. It also threatens the fragile eco system of the region.
The spill occurred early Wednesday when an outbound 600-foot Liberian-flagged tanker named The Tintomara collided with a barge pulled by a tugboat. The barge, a flat-bottomed boat, was carrying 400,000 gallons of thick, tar-like No. 6 fuel oil and was split in half, sending its contents pouring into the river.
The oil is too thick to evaporate from the river's surface and could sink. Authorities are hoping to remove the oil before that happens.
The barge was being pulled by the tugboat Mel Oliver -- the operator had only an apprentice mate's license, and no one else on board had a license to operate the boat on the river. An operator should have a master's license to operate the tugboat, Petty Officer Stephen Lehmann said.
Paul Book, vice president of operations facilities for American Commercial Lines Inc., said divers were assessing the barge as it lay against a bridge pier.
"We have reports of oil that is bubbling, coming from the bow and the stern compartments," he said at a news conference attended by several government officials.
V-shaped booms containing skimmers have been placed below each compartment to collect and siphon off the oil, he said. The operation will be done twice.
"We have high hopes that that will stop the release ... coming from the barge," Book said.
