TransCanada Applies for Keystone XL Route Approval

LINCOLN, NEBRASKA--(Marketwired - Feb. 16, 2017) - Media Advisory - TransCanada Corporation (TSX:TRP) (NYSE:TRP) (TransCanada) today announced it has filed an application with the Nebraska Public Service Commission (PSC) seeking approval for the Keystone XL pipeline route through the state.

"This application has been shaped by direct, on-the-ground input from Nebraskans," said Russ Girling, TransCanada's president and chief executive officer. "The thousands of Nebraskans we have met over the last eight years understand the value of this project and what it means to the state. As we have said consistently, safety and a respect for the environment remain our key priorities. We are listening and acting on what we have learned."

The proposed route was evaluated by the Nebraska Department of Environmental Quality and approved by the Governor of Nebraska in 2013. The preferred route avoids the area that is defined as the Nebraska Sandhills and is expected to have minimal environmental impacts in Nebraska. The review also included active consultation with landowners along the pipeline corridor where over 90 percent have signed voluntary easements to construct Keystone XL.

The PSC process is the clearest path to achieving route certainty for the project in Nebraska and is expected to conclude in 2017.

The company is committed to working productively with all stakeholders as this project moves forward. Keystone XL will benefit American workers, their families and the communities they live in as well as the U.S. economy. The pipeline will generate hundreds of millions of dollars in employee earnings in Nebraska, South Dakota and Montana alone during construction, and once operating will provide millions of dollars annually in local tax revenues.
