The Senate has approved legislation authorizing construction to begin on the controversial and long-delayed $3.3-billion Keystone XL oil-pipeline project. The Senate passed the bill on Jan. 29 by a 62-36 vote.
But the uncertainty hanging over the final leg of the pipeline continues. The project, proposed by Calgary-based TransCanada Corp., would run from Alberta's tar-sands region to Nebraska. It has been in limbo for more than three years, awaiting President Obama's approval.
