Despite rising concerns about the safety of the 61-year-old Straits pipeline, Enbridge increases flow in the line by 50,000 barrels a day.
"Democrats Dick Durbin of Illinois and Carl Levin and Debbie Stabenow of Michigan... say Enbridge Energy Partners recently began pumping an additional 2.1 million gallons of oil daily (that's an additional 50,000 barrels a day) through the line, built in 1953 and passing beneath the Straits of Mackinac where Lakes Huron and Michigan meet."
The senators said in their letter, "If the pipeline running beneath the Straits of Mackinac were to leak or burst, it could have devastating effects on the Great Lakes and the entire region's economy. The Great Lakes constitute 95 percent of the nation's surface fresh water supply..."
"An Enbridge pipeline (Line 6b) rupture polluted the Kalamazoo River in 2010. The senators say a similar break in the Straits could be disastrous." - Council of Canadians, Dec. 12, 2013
