The Keystone XL pipeline cleared a major hurdle on Monday after a Nebraska regulator approved an alternate route for the $8 billion project. Nebraska was the only state that had yet to approve the pipeline's route, and Monday's decision appeared to pass that final regulatory challenge. But the move could still be challenged in court. The five-member commission rejected TransCanada's preferred route and opted for one of the alternative routes that moves the pipeline farther east. The landowners who are in the way of the approved pipeline now need to be contacted in order for the project to move forward.
