"TRAVERSE CITY, Mich. -- Three U.S. senators asked a federal agency Wednesday for evidence that a pipeline crossing a section of the Great Lakes is safe, following a roughly 10 percent increase in its capacity to carry oil."
"Enbridge Energy Partners LP boosted the capacity of its Line 5 pipe earlier this year by 2.1 million gallons from 20.6 million. The line runs from Superior, Wis., to Sarnia, Ontario, passing through Michigan's Upper Peninsula and crossing the Straits of Mackinac, a five-mile-wide area where Lakes Huron and Michigan meet.
In a letter to the Pipeline and Hazardous Materials Safety Administration, Sens. Carl Levin and Debbie Stabenow of Michigan and Richard Durbin of Illinois noted the line is 60 years old and questioned its durability in the straits, where currents are strong and water temperatures variable."
