On December 22, 2008, the Montana Department of Environmental Quality 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. The 285-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 September 2, 2011, the U.S. Department of State released the Final Environmental Impact Statement for the project. The Montana Department of Environmental Quality was a cooperating agency on the Final EIS. The DRAFT EIS and the Final EIS can be found by following the various links below.
On March 30, 2012 DEQ issued a Certificate of Compliance for the project. The links to the Certificate of Compliance can be viewed further down this page. The Certificate of Compliance authorizes the Montana portion of the Keystone XL Pipeline and associated facilities. The pipeline would enter Montana at the United States-Canada border crossing near the Port of Morgan, Montana and extend southeast, crossing into South Dakota about 35 miles southeast of Baker. In the Montana, the length of the pipeline is approximately 285 miles. The associated facilities include but are not limited to: six pump station, three transmission lines, valves, and associated power supplies, temporary pipe storage areas, off right-of-way access roads, contractor yards, and temporary work areas.
