CALGARY -- The National Energy Board says it has ordered TransCanada Corp. to clean up sites that were developed as part of the Keystone XL pipeline project.

While inspecting sites in Alberta, the NEB found that TransCanada (TSX:TRP) had not yet completed reclamation at two drill site staging areas.

The areas include a section of the pipeline right-of-way and construction access roads at the Red Deer River and the South Saskatchewan River crossings.

The NEB issued the company a non-compliance order related to a lack of erosion control and weed management at the sites.

The order requires TransCanada to submit environmental surveys, monitoring and consultation reports and details of the reclamation scenarios by the end of the year.

The U.S. government denied TransCanada a permit to go ahead with the U.S. section of the pipeline last November.
