Great Lakes face threat from another Enbridge line

<> Great Lakes face threat from another Enbridge line - It's another segment of that same pipeline [Enbridge's Line 5 pipeline underwater, at the bottom of the Straits of Mackinac], out of the water and running through the Upper Peninsula along  U.S.-2 highway for nearly 90 miles between Manistique and St. Ignace, that poses a more immediate — and just as dire — threat to the lakes, according to a U.S. Coast Guard oil spill contingency specialist.
