Enbridge Energy is planning to replace an old pipeline that runs through Michigan.
It’s called Line 6B. That’s the same line that broke in Marshall nearly two years ago. The Environmental Protection Agency says more than one million gallons of tar sands oil spilled into Talmadge Creek and the Kalamazoo River.
Since the spill, Enbridge has been making repairs on that pipeline.
Joe Martucci is a spokesperson for Enbridge. He says the new pipeline will cut down on the number of repairs they’ll have to make.
"The purpose and need of it is integrity driven and also to increase the capacity of the line at the same time."
After the Marshall spill, Enbridge was ordered to reduce the pressure in Line 6B. That means there’s a lot less oil flowing through that pipeline now than there was before the spill.
Martucci says the new pipeline will allow Enbridge to double the amount of oil they can transport, up to 500,000 barrels per day. There is the potential for the pipeline to move as much as 800,000 barrels per day. But Joe Martucci says they would have to add more equipment to do so, and file a new application with the state of Michigan.
He says oil from Alberta’s tar sands region will be the main product in their new pipeline.
"The refiners and others are telling us they want more access to this oil and you know, it’s our job to try and provide them with a transportation capacity that makes that available."
Some landowners and environmental groups are worried about the idea of more tar sands oil moving through the Great Lakes region.
