Keystone XL Pipeline

The U.S. Department of State (State) prepared a draft supplemental environmental impact statement (draft SEIS) for the proposed Keystone XL Pipeline. The draft SEIS updates the 2014 final SEIS, analyzes the impacts related to changes in the Project since 2014, and incorporates current information and new studies, as applicable.

DOE's Western Area Power Administration has agreed to continue to be a cooperating agency for this SEIS (DOE/EIS-0433-S3) (similar to its role for the 2014 Keystone XL Final SEIS - DOE/EIS-0433-S1) and intends to use this SEIS as a basis for issuing a Record of Decision.
