LANSING, MI -- Gov. Rick Snyder has appointed a 15-member standing advisory board to implement recommendations on Michigan oil pipeline safety included in a state report focused on Enbridge's Line 5 pipeline under the Straits of Mackinac. The Michigan Pipeline Safety Advisory Board includes, among others, members of the U.S. Coast Guard, National Wildlife Foundation, Marathon Pipeline Co. and Enbridge Inc., which operates a 62-year-old twin line under the Mackinac straits that environmental advocates say threatens the lakes with an oil spill.
