(AP) -- Federal officials now estimate that more than 1 million gallons of oil may have spilled into a major river in southern Michigan. The U.S. Environmental Protection Agency released the update Wednesday night, shortly after the governor sharply criticized efforts to contain oil flowing down the Kalamazoo River.
Gov. Jennifer Granholm warned of a "tragedy of historic proportions" if the oil reaches Lake Michigan, which is still at least 80 miles downstream from where oil has been seen.
Enbridge Inc. owns the pipeline that leaked the oil, and its CEO said earlier Wednesday that the company has made "significant progress."
The company didn't return messages for comment after Granholm's statements.
