JACKSON, Miss. (AP) — The Coast Guard is letting vessels pass through a closed section of the Mississippi River at Vicksburg as it evaluates how traffic would affect efforts to remove and clean up oil from a leaking barge, a Guard spokesman said Wednesday.
Chief Petty Officer Paul Roszkowski told The Associated Press that a 16-mile stretch of the river remained technically closed four days after two barges struck a railroad bridge, even though some barges are being allowed to pass.
Roszkowski said that during a test period Wednesday, southbound barges were allowed to pass first — "methodically and slowly" — so crews could assess the effects on cleanup operations. The Coast Guard allowed the first northbound vessel to pass Wednesday afternoon.
"We understand the huge impact this (closure) is making on vessel traffic on the Mississippi River," Roszkowski said.
But, he added, "It's critical that the vessels going through there don't affect our operations."
Following the test period Wednesday, Coast Guard officials approved a plan that allows for northbound vessels to move through the area from sunset to sunrise and southbound vessels to continue their journeys in daylight hours, Roszkowski said.
"We will space things out to minimize possible waking and will continue to monitor and control vessel traffic in the area," he said.
Roszkowski said the Coast Guard decided to halt the oil's transfer to the new barge at night because it's safer and easier to see if any oil is escaping during the day. The river is not expected to reopen fully before the transfer and cleanup is complete.
A Coast Guard "safety zone" extends the width of the river for 16 miles, which means it is effectively closed because barges must have permission to pass, he said.
Petty Officer 1st Class Matt Schofield said Wednesday that at times there have been more than 70 vessels, including towboats, and hundreds of barges idled at the closed section of the river, one of the nation's vital commerce routes. The numbers fluctuate as the barges are let through and others arrive at the closed section.
The leaking barge has been pushed against the Louisiana shore, across from Vicksburg's Riverwalk and Lady Luck casinos, since Sunday's crash.
Schofield said the Coast Guard started pumping oil from the leaking barge onto another barge — a process known as lightering — about 2:30 p.m. CST on Wednesday.
It's not clear how long that process would take.
Severe weather that swept through the area overnight Tuesday shut down cleanup operations for a time, but crews were working again Wednesday morning, Schofield said.
The Coast Guard said 7,000 gallons of crude oil were unaccounted for, but it's not clear if it all spilled into the river or if some seeped into empty spaces inside the barge.
Schofield said Wednesday that oil is still seeping from the damaged barge.
He said most of the oil was being contained, but some had escaped the containment booms Wednesday and a sheen was visible on a section of the river. Skimmers were cleaning it up, he added, saying 3,900 gallons of an oil-and-water mixture had been sucked from the river since the cleanup began.
