The following is the text of a press release issued by the U.S. Coast Guard:
(DULUTH, Minn.) — The Coast Guard is investigating the cause of a small hull fracture reported on the Canadian vessel Atlantic Huron, at anchor outside of the Duluth-Superior Harbor, Friday evening.
The Coast Guard is also investigating a fluorescent green discoloration reportedly resulting from the crew's efforts to determine the extent of the fracture, in the #5 ballast tank of the ship, with a dye penetrant, which has been reportedly approved for marine use.
Coast Guard Marine Safety Unit Duluth personnel are responding to the incident to determine the extent of the reported damage, verify adequacy of the temporary repairs, and ensure that the dye used is in compliance with the Clean Water Act. Assisting in the response are crews from Coast Guard Station Duluth, and Sector Sault Sainte Marie, Mich.
The vessel's owner, V Ships Canada, Inc., is fully cooperating with the Coast Guard investigators and pollution responders.
