Trump tries fresh approach with long-delayed Keystone XL pipeline

U.S. President Donald Trump on Friday signed a new permission for TransCanada Corp to build the long-delayed Keystone pipeline for imports of Canadian oil, replacing his previous permits in a fresh attempt to get around the blocking of the $8 billion project by a court in Montana. In granting the permission in an executive order, Trump revoked a previous permit for the pipeline issued in March 2017 and an executive order approving the project he issued two days after taking office in January that year. It was not immediately clear whether under the new approval the pipeline, which would carry 800,000 barrels per day of crude from Canada’s oil sands to refineries along the U.S. Gulf of Mexico, would have to undergo extensive new environmental reviews.
