Welcome to the California Public Utilities Commission (CPUC) website for the environmental review of Southern California Edison’s (SCE’s) proposed Riverside Transmission Reliability Project (RTRP or project) in Riverside County, California. SCE submitted an application to the CPUC for a Certificate of Public Convenience and Necessity (CPCN) for this project on April 15, 2015, and an amended application on April 30, 2015. In August 2016, SCE submitted project revisions that included constructing a portion of the transmission line underground (See Background and Project Description below). This site provides access to public documents and information relevant to the CPUC’s California Environmental Quality Act (CEQA) process.

Background and Project Description

SCE and the City of Riverside's Municipal Utility Department (known as Riverside Public Utilities [RPU]) jointly planned the RTRP. RPU is a consumer-owned water and electric utility that has been providing services throughout the City of Riverside since 1895. The project would be owned and operated by both RPU and SCE. The RPU would own and operate certain elements of the RTRP including the new 69-kV Wilderness Substation, 69-kV subtransmission lines, and interconnection and telecommunication facilities. The SCE CPCN application covers the construction of RTRP elements that would be owned and operated by SCE, which would include:

    Approximately 8 miles of new overhead 230-kilovolt (kV) transmission line;

    Approximately 2 miles of new underground 230-kV transmission line;

    New 230-kV Wildlife Substation;

     Modifications of existing overhead distribution lines;

     Modifications at existing substations; and

     Telecommunication facilities between the existing Mira Loma and Vista Substations and the proposed Wildlife Substation.

The RTRP was first proposed by RPU. Acting as the CEQA Lead Agency, the City of Riverside prepared an Environmental Impact Report (EIR) to analyze the environmental impacts from construction, operation, and maintenance of the RTRP.  While there are separate permit requirements and authorizations required for RPU and SCE, the project EIR considered the “whole of the action” under CEQA (CEQA Guidelines §15378[a]) since neither the RPU elements nor the SCE elements could operate independent of one another. The City of Riverside certified the 2013 RTRP Final EIR and approved the project on February 5, 2013.

Following certification of the RTRP EIR, residential and commercial developments within SCE’s proposed transmission line route were approved by the City of Jurupa Valley. Construction of several of these developments has begun or been completed; therefore, construction of the original RTRP transmission line route would require SCE to claim eminent domain through recently entitled developments including the Lennar Homes’ Riverbend Community, the Vernola Marketplace Apartment Community, and the Stratham Homes Harmony Trails Subdivision. In September 2016, SCE revised the proposed transmission line route to avoid these three development projects. The September 2016 transmission route revisions were not included in the 2013 RTRP EIR and have not yet undergone environmental review.

CPUC is the next-in-line public agency with discretionary approval of the CPCN. The CPUC has determined that changes in the baseline physical condition (development within the proposed transmission alignment) and changes in the project description (SCE modifications to avoid the new development) require additional analysis under CEQA. 

Detailed maps of the proposed route and project components can be viewed here.

CPCN Application

SCE filed an Application for a CPCN (A.15-04-013) on April 15, 2015, which included the certified 2013 RTRP Final EIR prepared by the City of Riverside and associated administrative record. The RTRP Final EIR was filed by SCE as equivalent information to a Proponent’s Environmental Assessment. SCE filed an Amended Application on April 30, 2015.

Environmental Review

Draft Subsequent Environmental Impact Report

The CPUC has determined that a Subsequent EIR is required for the project to address potential impacts resulting from project revisions and changes in baseline conditions following the certification of the 2013 RTRP Final EIR. The Draft Subsequent EIR will be made available on this website once it is completed and published. To receive notification when the Draft SEIR becomes available, contact riversidetrp@panoramaenv.com

CEQA Initial Study Checklist

The purpose of the Initial Study (IS) Checklist is to define the scope of the environmental impact analysis for the CPUC Subsequent EIR. The checklist analyzes:
  1. The changes in the SCE project and
  2. Effects related to changes in baseline physical conditions that occured following certification of the 2013 RTRP EIR
These changes are evaluated at a screening level to determine whether the changes could result in new significant impacts or a substantial increase in the severity of an environmental impact that was previously evaluated in the 2013 RTRP EIR. The IS Checklist will be used by the CPUC to define the CEQA resource topics for which subsequent analysis is required.

A copy of the IS Checklist is available here.

Notice of Preparation and Scoping

Issuance of a CEQA Notice of Preparation (NOP) is the first step in the EIR Process. The NOP provides a description of SCE's application and the revised project as well as a summary of environmental topics to be considered in the Subsequent EIR. The NOP was issued on January 25, 2017 and is available here

The scoping period began on January 25 and ended on February 24, 2017. In order for the public and regulatory agencies to have an opportunity to ask questions on the scope of the Subsequent EIR, the CPUC, as the CEQA lead agency, held a scoping meeting for the public on February 8, 2017 at Jurupa Valley High School. The CPUC described SCE's proposed project and the CPUC review process. Public comments on the scope and issues to be addressed in the Subsequent EIR were accepted during the meeting.

A copy of the presentation is available here: English | Spanish

The project fact sheet is available here: English | Spanish
* The listed fact sheets provide the corrected project website URL.

Scoping Report

The CPUC prepared a Scoping Report that documents the scoping activities and oral comments from the scoping meeting, as well as the written comments submitted in response to the NOP. This report serves as an information source to the CPUC in the determination of the range of issues and alternatives to be addressed in the Draft Subsequent EIR.
