Keystone XL Pipeline
December 22, 2008 DEQ received an application from TransCanada and ConocoPhillips for a Certificate of Compliance under the Major Facility Siting Act to construct and operate a 36-inch crude oil pipeline in eastern Montana. Keystone is a limited liability company, organized under the laws of the State of Delaware, and owned equally by affiliates of TransCanada Corporation, a Canadian public company organized under the laws of Canada, and ConocoPhillips Company, a Delaware corporation. The 280-mile portion of the pipeline in Montana would be part of a longer 1,980-mile project beginning in Hardisty, Alberta, and ending along the Texas Gulf Coast. On March 30, 2012 DEQ issued a certificate of Compliance for the project. It may be viewed at the Keystone Certificate page.
