Michigan’s Department of Environmental Quality’s Petroleum Pipeline Task Force issued a report that recommended that heavy crude and oil sands be kept out of an Enbridge Inc. pipeline that crosses the Mackinac Straits between Lakes Huron and Michigan. The July 14 report also called for mandatory full insurance coverage for the 5B pipeline, which Enbridge owns and operates; an examination of alternatives to the 545-mile, 30-in. line from Superior, Wis., to Sarnia, Ont., which was built in 1953; requirements for Enbridge to disclose safety inspections; and creation of a public pipeline safety advisory committee. “These recommendations are tough but fair and are clear about responsibilities every Michigan citizen has as a steward of the Great Lakes,” said Michigan Atty. Gen. Bill Schuette (R), who formed the multiagency taskforce with DEQ Dan Wyant in 2014 to address safety concerns about various pipelines across the state. “Certainly, the Straits Pipelines would not be built today, so how many more tomorrows Line 5 should operate is limited in duration,” Schuette said.
