The U.S. Coast Guard issued a press release this morning saying all the fuel valves and vents connected to the fuel tank on the sunken barge, the Arthur J, have been plugged.
Crews continue to work on salvaging the 110-foot dredge barge and 38-foot tug that sank yesterday morning one mile off the coast of Lakeport, Michigan.
From their release:
The Arthur J has ten vents to its fuel tank and responders where able to plug four of them early Thursday afternoon, but six remained open until responders were able to plug them late Thursday night.
The impact to the shoreline has been minimal; however there is visible sheening along the shores of Lakeport, but there has been no report of a thick product wash ashore. However, there is still a strong diesel odor in the air, so residents and visitors of the lower Lake Huron area are encouraged to avoid areas where there is an odor in the air. Those who live in the area should remain inside with doors and windows closed as much as possible.
The Coast Guard says the Michigan State Health Department has closed beaches from the Blue Water Bridge north to Lakeport State Park.
The diesel fuel that did spill remains on the lake. No wildlife impacts have been reported yet. The Coast Guard says "weather and lake conditions are not optimal for product clean up, but the clean-up efforts continue vigilantly."
The sunken dredge barge and tug were owned and operated by MCM Marine.
Early reports indicated the barge and tug began taking on water around 4 a.m. yesterday. The Coast Guard reports the cause of the accident at this time is still unknown.
