Companies will study risks, changes to underwater pipeline

Enbridge Line 5 in the Straits of Mackinac.

MACKINAC CITY, Mich. (AP) — The state of Michigan has tapped two companies to analyze the financial risk of an oil pipeline rupture in the Straits of Mackinac and evaluate any alternatives to the pipeline.

Enbridge Energy, based in Calgary, Alberta, has agreed to pay $3.5 million but will not oversee the studies. Enbridge owns the twin oil pipelines in the area where lakes Huron and Michigan converge.

Det Norske Veritas will determine how much money would be needed to clean up an oil spill. Dynamic Risk Assessment Systems will study alternatives to Line 5. The announcement was made Tuesday.

Line 5 carries nearly 23 million gallons of light crude oil and liquefied natural gas daily. It runs across Wisconsin and Michigan’s Upper Peninsula before entering the Straits of Mackinac. It ends in Sarnia, Ontario.
