It appears as though the Keystone XL pipeline will be exempted from the presidential directive that all American pipeline systems be built with American steel.
White House spokesperson Sarah Huckabee Sanders said last week that it would be difficult to use only US products as the pipeline is already under construction. “The way that executive order is written, it’s specific to new pipelines or those that are being repaired."
Trump had previously said that if pipeline operators "want a pipeline in the United States, they’re going to use pipe that’s made in the United States.”
The Keystone pipeline would run from Canada to refineries in the Gulf Coast. The Dakota Access line would move North Dakota oil to Illinois, and that project is nearly complete.
