The company behind the Keystone XL pipeline on Monday asked the U.S. government to suspend its permit application, throwing the politically fraught project into an indefinite state of limbo, beyond the 2016 U.S. elections.

Calgary, Alberta-based TransCanada Corp. sent a letter to the State Department, which reviews cross-border pipelines, to suspend its application while the company goes through a state review process in Nebraska it had previously resisted. The move comes in the face of an expected rejection by the Obama administration and low oil prices that are sapping business interests in Canada’s oil reserves.

“In order to allow time for certainty regarding the Nebraska route, TransCanada requests that the State Department pause in its review of the Presidential Permit application for Keystone XL,” the company said in the suspension request reviewed by The Wall Street Journal. “This will allow a decision on the Permit to be made later based on certainty with respect to the route of the pipeline.”
