COAST GUARD INVESTIGATING POSSIBLE FUEL SPILL IN UPPER PENINSULA RIVER
The U.S. Coast Guard is still waiting on lab results to find out what was
floating down an Upper Peninsula river, but they think it could be diesel
fuel.  The possible fuel spill happened in Sault Ste. Marie and floated
down the St. Mary's River and Power Canal.  They believe it could be about
50 gallons of diesel fuel.  Right now, the spill is not a major threat.
Guardsmen say the source of the leak has been contained near a ferry
docked in Sault Ste. Marie Ontario.  If you see any sheen in the water,
stay away from it and let the Coast Guard know.
