Keystone XL Pipeline government studies recently released
If constructed, the Keystone XL pipeline would transport crude oil (e.g., synthetic crude oil or diluted bitumen) derived from oil sands in Alberta, Canada to destinations in the United States. Because the pipeline crosses an international border, it requires a Presidential Permit that is issued by the Department of State (DOS).
Here are some recent documents related to the Keystone XL pipeline:
Oil Sands and the Keystone XL Pipeline: Background and Selected Environmental Issues (Report by the Congressional Research Service issued February 23, 2013.)
Draft Supplementary Environmental Impact Statement (SEIS) (Draft technical review of potential environmental impacts associated with the proposed project, including impacts from construction, impacts from potential spills, impacts related to climate change, and economic impacts. Issued by State Department on March 1, 2013. A 45-day public comment period will begin when EPA posts the Draft SEIS on its Web site.)
