TRAVERSE CITY, Mich. (AP) — Michigan officials have released a consulting firm’s draft report listing alternatives for dealing with twin oil pipelines beneath the waterway where Lakes Huron and Michigan meet.
The state commissioned the report as environmental groups push to decommission the nearly 5-mile-long (8-kilometer-long) section of Enbridge Inc.’s Line 5 in the Straits of Mackinac, which was laid in 1953. State Attorney General Bill Schuette endorsed a shutdown Thursday.
The report by Dynamic Risk Assessment Systems Inc. lists six choices. Among them are continuing to operate the pipelines or removing them. Others include building a new pipeline that wouldn’t cross open Great Lakes waters; moving Line 5’s oil through other pipelines; using rail cars, trucks or barges to transport oil; or putting new pipelines in the straits that would run through a trench or tunnel.
The report doesn’t endorse a particular alternative but analyzes each for technical and cost feasibility.
