Welcome to the California Public Utilities Commission (CPUC) website for the environmental review of the proposed construction of the Ten West Link Project (proposed project) located near the Interstate 10 corridor in Western Riverside County, California. The applicant for the proposed project is Delaney Colorado River Transmission LLC (DCRT). This website provides information relevant to the California Environmental Quality Act (CEQA) review process.

The Bureau of Land Management (BLM), in its role as the National Environmental Policy Act (NEPA) lead agency, prepared an environmental impact statement (EIS) for the proposed project. The BLM published the Final Environmental Impact Statement in September 2019. A portion of the proposed project is located within the State of California and requires approval from the CPUC. Because this approval is a discretionary action, the CPUC must comply with the requirements of CEQA. The CPUC relied on the BLM EIS per CEQA Guidelines, Section 15221. Click here for the letter providing notice pursuant to CEQA Guidelines Section 15225(a) to interested parties that the Energy Division of the CPUC believes that the EIS meets the requirements of CEQA, and that the CPUC intends to use the EIS in place of an Environmental Impact Report (EIR) in deciding whether to approve, conditionally approve, or deny DCRT’s application for a Certificate of Public Convenience and Necessity for the Ten West Link Project. The environmental documents prepared for the proposed project can be accessed on the BLM Ten West website.

On November 5, 2021 the Commission issued Decision 21.11.003 granting DCRT a Certificate of Public Convenience and Necessity for the Ten West Link Project (see Agency Decisions below).

The following timeline represents the overall environmental review process. The blue boxes represent the timeline of when tasks were completed.

Background

DCRT filed an application for a Certificate of Public Convenience and Necessity (Application A.16-10-012) for the proposed project with CPUC on October 12, 2016, accompanied by a description of proposed transmission facilities. On September 14, 2014, DCRT filed a right-of-way application (SF-299) with the BLM that proposes to construct, operate, maintain, and decommission an electric transmission project in western Arizona and eastern California. The proposed project would consist of a 500-kilovolt (kV) transmission line traversing approximately 114 miles, with a 17-mile segment in California. The proposed project would increase transmission capacity by 3,200 megawatts and provide interconnection capability for new energy projects located near the proposed project.

 

Project Description

The proposed project includes installation of a 500-kV transmission line, transmission supporting structures between 72 and 190 feet in height, conductors, overhead ground wire, and a new series compensation system substation.

Project construction of the entire 114-mile transmission line is expected to require approximately 38 months to complete.

The 17-mile portion of the proposed project in California would begin at the Colorado River Substation west of the City of Blythe and run eastward to the Colorado River near the Interstate 10 corridor in western Riverside County, California (see the Location Map). For a description and the location of the project components in Arizona, please refer to the BLM Ten West website.
