The state of Michigan is suing a Great Lakes tugboat owner for allegedly damaging pipelines sitting on the bottom of Lake Huron.
Michigan Attorney General Bill Schuette said he will bring a civil action against Vanenkevort Tug and Barge for dragging an anchor across state bottomlands and submerged electric and petroleum pipelines.
Schuette said the incident caused the release of hazardous mineral oil into the Straits of Mackinac -- a "no-anchor" zone -- and potentially harmed aquatic life and the lakebed.
