The future of a controversial and much-delayed oil pipeline in northern Minnesota is in doubt after the company proposing it announced a big investment in a different pipeline that would also transport North Dakota crude — but without crossing Minnesota.
Calgary-based Enbridge Inc. announced late Tuesday that it's buying a $1.5 billion stake in the Bakken Pipeline system, which includes the Dakota Access Pipeline. It will move oil from North Dakota's Bakken range through South Dakota and Iowa to a tank farm in Patoka, Ill., about 70 miles east of St. Louis.
The $2.6 billion Sandpiper pipeline would run from the Bakken oil fields through Minnesota — including pristine lake country — to a terminal in Superior, Wis. The pipeline has drawn fire from environmentalists and American Indian tribes and has been winding through the Minnesota regulatory process for the past 2½ years.
Enbridge doesn't expect construction on Sandpiper to begin until 2019. The Dakota Access pipeline is projected to be in service by the end of 2016.
Enbridge has formed a joint venture with Marathon Petroleum to buy a stake in the Bakken Pipeline System. Marathon has been a key partner in Sandpiper, with plans to finance 37 percent of the pipeline and become one of its major customers.
But when the new Bakken Pipeline deal is complete, Enbridge and Marathon plan to terminate their joint venture agreements for Sandpiper, Enbridge said in a statement. With that, Sandpiper's future is murky.
"Enbridge continues to believe the Bakken region is a highly productive and attractive basin, which has significant crude oil supply growth potential that will require additional pipeline capacity in the future," the company said in a press statement. "The scope and timing of the Sandpiper Pipeline Project will be evaluated during the quarter to ensure that it is positioned to meet the growing need for pipeline capacity."
Enbridge declined further elaboration.
