Summary

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

DOE's Western Area Power Administration 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. WAPA’s mission allows open access to the federal transmission system. Any entity requesting interconnection to the federal transmission system must submit an application for interconnection. Local power cooperatives have submitted requests to interconnect with the WAPA transmission system in order to serve the electrical needs of Pump Stations 9 through 13 and Pump Stations 17 through 19, as well as Pump Station 21. WAPA’s purpose and need is to consider and respond to these interconnection requests from the local power cooperatives, and the related construction or upgrading of any WAPA-owned facilities as a result of the requests.

Project cancelled by project proponent in 2021.
