UNITED STATES -- The highly controversial Keystone XL pipeline project has cleared a significant hurdle.

An environmental impact study conducted by the U.S. Department of State found that the project would have little impact on the area along its route.

The proposed 875 mile long pipeline would run from Canada to Nebraska, entering the U.S. through Montana. It would then connect to a pipeline that is already under construction further south.

Because it crosses an international boundary, it needs the president's approval.

The environmental study is part of that decision making process, as is a 45 day public comment period, which is expected to begin sometime next week.
