Michigan’s governor is speaking out against a plan by operators of a major natural gas pipeline to use it to move bottlenecked crude oil to the Gulf.

Gov. Rick Snyder and others have filed a motion with the Federal Energy Regulatory Commission to “intervene and protest” the move by Trunkline Gas Co., arguing that abandoning a natural gas pipeline that supplies nearly a third of Michigan’s natural gas would not serve citizens’ energy needs as furnaces are firing up for the winter.
