The proposed Keystone XL project consists of a 1,700-mile crude oil pipeline and related facilities that would primarily be used to transport Western Canadian Sedimentary Basin crude oil from an oil supply hub in Alberta, Canada to delivery points in Oklahoma and Texas. This EIS, prepared by the Department of State, evaluates the potential environmental impacts of the proposed Keystone XL project. DOE’s Western Area Power Administration, a cooperating agency has jurisdiction over certain proposed transmission facilities relating to the proposal. For more information and to view the original Keystone XL Project Final EIS, see Department of State’s Keystone XL Project page.
The Department of State, with DOE as a cooperating agency, prepared a Supplemental EIS to evaluate the potential environmental impacts of a revised proposal for the Keystone XL pipeline and related facilities. More information on that 2014 Supplemental EIS is available here. (See also DOE/EIS-0433-S1.)
The Department of State, with DOE as a cooperating agency, prepared a second (Draft) Supplemental EIS -- to evaluate the potential environmental impacts of the Mainline Alternative Route of the Keystone XL Pipeline in Nebraska. More information on the second Supplemental EIS is available here. (See also DOE/EIS-0433-S2.)
Currently, the Department of State, with DOE's Western Area Power Administration as a cooperating agency, is preparing another Supplemental EIS (DOE/EIS-0433-S3) to update the 2014 final SEIS (DOE/EIS-0433-S1), analyze the impacts related to changes in the Project since 2014, and incorporate updated information and new studies, as applicable.
