November 10, 2011 The Department of State postponed a final decision while investigating "potential alternative routes around the Sandhills in Nebraska" in response to concerns that the project was not in the United States' national interest. In its response, TransCanada pointed out fourteen different routes for Keystone XL were being studied, eight that impacted Nebraska. They included one potential alternative route in Nebraska that would have avoided the entire Sandhills region and Ogallala Aquifer and six alternatives that would have reduced pipeline mileage crossing the Sandhills or the aquifer.
