Environmental Groups Seek Probe of Keystone XL Pipeline Review

U.S. environmental groups called on the State Department’s inspector general to investigate what they called “illegality and/or abuse of authority” in the department’s review of TransCanada Corp.’s Keystone XL pipeline.

The proposed $7 billion pipeline would deliver crude from the oil sands of Canada to refineries on the U.S. Gulf Coast. The State Department, which has jurisdiction because the project would cross an international boundary, plans to decide whether to grant approval by the end of the year.
