Governor Rick Snyder has cited the need for propane, for winter heating, in his refusal to halt the flow of crude oil through pipelines in a Great Lakes waterway. Snyder says the twin pipelines were inspected for gaps in exterior coating, and said there was no imminent threat of a spill. At the same time, according to the Associated Press, Snyder also turned down two other proposals from critics of Enbridge’s Line 5.
