Study: Straits oil spill could affect vast shoreline areas in the U.S., Canada

ANN ARBOR, Mich. — A newly released study says hundreds of kilometres of Lake Michigan and Lake Huron shoreline are at risk of contamination if oil pipelines in the Straits of Mackinac rupture.

The report by the University of Michigan Water Center is based on 840 computer simulations of possible spills from twin lines that run across the floor of the straits linking Michigan's two peninsulas.

They are owned by Enbridge, which says they've never leaked and remain in good shape.

Environmentalists are pushing to have them removed.

David Schwab, a hydrodynamics expert who directed the study released Thursday, says when all simulated spills are plotted on a map, 1,160 kilometres of shoreline in the U.S. and Canada are considered potentially vulnerable.

High-risk areas include Mackinac Island and shores near Mackinaw City.
