Michigan’s new governor and attorney general moved to review the legality of a contentious state deal to run an oil pipeline beneath a crucial section of the Great Lakes. Democratic Gov. Gretchen Whitmer announced her request for a legal opinion from Attorney General Dana Nessel, a Democrat who welcomed the opportunity and expressed concern with a law that facilitated the agreement between the state and Canadian pipeline company Enbridge. Such opinions, while not the same as legal rulings, are considered to bind state agencies unless reversed by a court. Both Whitmer and Nessel had questioned the deal before taking office.The Republican-led Legislature and GOP former Gov. Rick Snyder rushed to enact the law after Whitmer was elected in November. The new Mackinac Straits Corridor Authority then swiftly approved the proposal to drill a tunnel through bedrock up to 100 feet (30.4 meters) below the more than 4-mile-wide (6.4 kilometer) channel that links Lakes Huron and Michigan. A new segment of pipeline will extend through the tunnel, replacing twin pipes that have lain along the lake bed since 1953. They are part of Enbridge’s Line 5, which carries crude oil and natural gas liquids used in propane from Superior, Wisconsin, through northern Michigan to refineries in Sarnia, Ontario.
