Line 67 is a 1,600 kilometre tar sands pipeline that currently carries 450,000 barrels per day pipeline from Hardisty, Alberta to Superior, Wisconsin, which is situated on the western tip of Lake Superior. Calgary-based Enbridge wants to increase this pipeline's capacity to 880,000 barrels per day.
In order to avoid the approval process that has delayed the TransCanada's Keystone XL pipeline, Enbridge has hatched a plan.
This is what they came up with. Line 67 will take the tar sands bitumen from northern Alberta to Gretna, Manitoba, which is located about 2.4 kilometres north of the North Dakota border. There the bitumen would flow into Line 3, which would carry it about 25 kilometres into the United States. At that point, Line 3 would connect back to Line 67 and the bitumen would continue on to its terminus at Lake Superior.
