 The Minnesota Court of Appeals has dismissed an appeal blocking the construction of the Enbridge Energy Line 3 oil pipeline. That appeal was filed during the final days of Governor Mark Dayton's administration. The Commerce Department and other groups who filed appeals have a 20-day window to file a petition for reconsideration. Current Minnesota Governor Tim Walls is not indicated if he will file such a petition. Walls told reporters last month that he planned to review the appeal with the Commerce Commissioner before making up his mind. Line 3 was built in the 1960s. Alberta-based Enbridge says a replacement is needed to ensure reliable deliveries of crude oil to Midwestern refineries. The Minnesota Public Utilities Commission approved the project last June.
