Critics seek to stop Great Lakes pipeline run by company with poor safety habits

Environmental groups say Line 5 poses a major threat and is run by Canada's Enbridge which has a long record of mismanagement

A coalition of environmental groups and newly elected Democrats in Michigan are seeking to shut a controversial pipeline through the Great Lakes they say represents a major environmental threat and is being run by a company with a long record of mismanagement, poor safety habits and deception.

Canadian oil giant Enbridge wants to replace an ageing pipeline called Line 5 that cuts through the Great Lakes, which hold more than 90% of the nation's freshwater. It transports about 540,000 barrels of oil and liquid natural gas daily in 4.4 miles of pipelines that are exposed on the lake floor in the Mackinac Straits.
