 Governor Dayton has vetoed a bill that would have allowed Enbridge Energy to bypass the State Public Utilities Commission and proceed with replacing its aging Line 3 crude oil pipeline across northern Minnesota. The Democratic governor said in a letter to Republican House Speaker doubt that the bill preempts the long-standing Public Utility Commission process. The commission is scheduled to vote late next month on whether the project is needed and what route it should take. Line 3 is opposed by environmental and tribal groups that fear the impact on climate change and pristine waters. GOP lawmakers said the Public Utilities Commission process has taken too long and that the new Line 3 would spur the economy in northern Minnesota.
