LAKEWOOD, Colo. – Western Area Power Administration is extending its public scoping period for collecting comments on the environmental review of the proposed Colusa-Sutter Transmission Line , or CoSu Line.

WAPA initiated a 60-day public scoping process in Colusa and Sutter Counties, California, Dec. 18, 2015, by publishing a notice of intent in the Federal Register (80 FR 79037). The 60-day extension provides additional opportunities for the public to comment and identify issues, opportunities and concerns that should be considered in the draft environmental impact statement/review. Comments received by April 18, will be considered in defining the scope of the EIS/EIR. Additional opportunities for public participation will be provided once the draft EIS/EIR is published. 

The CoSu Line would enhance the reliability of the electrical grid in Northern California by providing a new connection to the existing California-Oregon Transmission Project line in Colusa County, California and increase Sacramento Municipal Utility District’s ability to deliver clean power to the Sacramento area from the Pacific Northwest and other energy markets. The proposed project would link to a new substation near the existing O'Banion Substation in neighboring Sutter County. 

Four of six public meetings have already been held about this project in Colusa and Sutter counties, two meetings in each county respectively. The final two public meetings focused on scoping are planned for Feb. 2 and 4, 2016. There the public, agencies and other stakeholders can learn about the proposed project and provide comments to inform Western and SMUD of their issues and concerns at this earliest stage of the environmental review process. Information about the public meetings, including locations and how to provide comments, is available on the project website at No action will be taken on the project proposal until after the environmental review is completed.
