Lawmakers are ready to pursue multiple options to push a decision on the pipeline, following the release of the State Department’s final environmental review of the $5.4 billion project.

The environmental analysis, released on Friday, said Keystone XL would not significantly add to greenhouse gas emissions, prompting a call for “no more excuses” from advocates of the pipeline.

And to stop further delays, Hoeven and other lawmakers might propose legislation that would create a deadline for a decision.
