State utility regulators on Tuesday unfroze the approval process for Enbridge Energy's plan to replace its aging Line 3 crude oil pipeline across northern Minnesota, directing a state agency to fix the deficiencies identified by a court in the project's environmental review.

The Public Utilities Commission voted unanimously during a hearing that lasted just 12 minutes to ask the state Commerce Department to conduct a further analysis of the potential effects of oil spills in the Lake Superior watershed and report back within 60 days.


The decision represented the first forward motion on the project in months while legal challenges by environmental and tribal groups played out in court. The Minnesota Court of Appeals upheld most of the environmental review in June except for the inadequacies regarding Lake Superior. The Minnesota Supreme Court declined last month to hear challenges by the opponents to the environmental review on other grounds. But further appeals from opponents are possible.

Water certification denied for Line 3; re-filing expected

Line 3, which was built in the 1960s and is increasingly subject to corrosion and cracking, runs from Alberta to Enbridge's terminal in Superior, Wisconsin, near Lake Superior. Calgary, Alberta-based Enbridge wants to replace the pipeline because it can run at only about half its original capacity.

Environmental and tribal groups have been fighting the project, saying it would aggravate climate change and risk spills in pristine waters where Native Americans harvest wild rice.

Enbridge has completed the new segments in Canada and Wisconsin, but has had to hold up construction of the $2.9 billion segment in North Dakota and Minnesota until it clears the final hurdles in Minnesota.

Once the department completes the revised environmental review, there will be a public comment period before the commission decides whether the update is adequate. The commission would then decide whether to reissue two key approvals it granted over a year ago - the certificate of need and route permit. That whole process is expected to take at least until sometime early next year.

Other potential delays could come from court challenges to the certificate of need and route permit that remain pending. The delay on finalizing the environmental review has also held up permits from other agencies .

Enbridge spokeswoman Lorraine Little said the company isn't currently projecting a date for when construction might begin or when the Minnesota portion of the project would go into service.
