MARSHALL (WKZO) -- The cleanup of the Kalamazoo River from the 2010 Enbridge oil spill will cost nearly 800-million dollars when it's all done.  The Canadian company puts its estimate at 785-million dollars in a quarterly filing with the U.S. Securities and Exchange Commission.  That includes ongoing costs of cleaning up the river, which was contaminated by roughly 800-thousand gallons of crude oil two years ago.
