MLive and the Grand Rapids Press were were able to obtain, via a FOIA (Freedom of Information Act) request of NOAA, the predictions of what an oil spill in the Straits of Mackinac would look like.
Six images, obtained by MLive and The Grand Rapids Press through the Freedom of Information Act, show the simulated oil spill trajectory that local, state and federal agencies were using in September when Enbridge Inc. practiced a cleanup scenario imagining a break in its Straits of Mackinac pipeline.
"In the slides, surface oil floats around the straits for a day before starting to beach along the Lower Peninsula. Mackinaw City functions as a kind of ground zero in the model, with the heaviest concentrations washing ashore on the western side of Bois Blanc Island in Lake Huron 60 to 72 hours after release." - MLive
