UPDATE 10:49am | President Trump announced detailed plans on the Keystone XL pipeline following his official approval.
He called it "the most incredible pipeline known to man or woman." According to Trump, it will span 900 miles and deliver up to 800,000 gallons.
The project will cost $8 billion dollars.
UPDATE 8:56am | TransCanada this morning announced it received the State Department permit.
Now the company needs to receive approval of the pipeline's route through Nebraska, a process that could take several more months, according to POLITICO.
President Donald Trump has given the official green light to construct the Keystone XL pipeline.
The Trump administration gave the pipeline its key federal permit Friday, clearing a major hurdle for the project that former President Barack Obama rejected in 2015.
The State Department announced Friday morning that its under secretary for political affairs, Tom Shannon, issued the permit, two months after President Trump signed an executive order to revive the project after Obama’s rejection.
