Construction of a new pipeline, known as Keystone XL, that will feed crude in a 36-inch pipeline from Hardisty, Alberta to Steel City, Nebraska. The pipeline would be 1,930 kilometers (1,199 miles) in length, and be able to handle 830,000 barrels per day. 
The project received approval from President Trump in March 2017, and from the Nebraska Public Service Commission in November 2017.
The Government of Alberta has agreed to invest approximately $1.1 billion US as equity in the project in March 2020, and construction activities are to begin immediately.
On January 20, 2021, President Biden rescinded the previous presidential approval. TC Energy has suspended construction activities at this time. 
TC Energy confirmed termination of Keystone XL Pipeline Project on June 9, 2021.
