Enbridge Inc. is seeking State Department approval for a sharp increase in its oil deliveries from Canada's tar sands region to Superior.
The Milwaukee Journal Sentinel said government documents show Enbridge potentially could nearly double its capacity, indicating that the pipeline company has plans to transport more Canadian oil through Minnesota to Wisconsin than previously reported. Enbridge also would move more oil to Superior from North Dakota oil fields.
The State Department reported in the Federal Register on Friday that Canada-based Enbridge wants to boost capacity from between 450,000 and 500,000 barrels a day to 570,000 a day. In a second phase, Enbridge is seeking to ship up to 880,000 barrels daily.
No new pipelines would be built, but the company would upgrade its pumping stations in Minnesota and Wisconsin.
