Welcome to the California Public Utilities Commission (CPUC) website for the environmental review of a proposed 500-kilovolt (kV) transmission line from the Antelope Substation in northern Los Angeles County to the Pardee Substation in the City of Santa Clarita. Southern California Edison (SCE) submitted an application for a Certificate of Public Convenience and Necessity (CPCN) for this project to the CPUC on December 9, 2004. SCE has also submitted an application for a Special Use Easement to the USDA Forest Service. The proposed project is subject to review under both the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA). This site provides access to public documents and information relevant to the CEQA and NEPA review processes.

Background

SCE has filed applications with the CPUC and the Forest Service to construct a new, 25.6-mile 500-kV transmission line between SCE's existing 220-kV Antelope and Pardee substations in Los Angeles County, California. The proposed 500-kV transmission line would replace an existing 66-kV line that traverses the majority of the proposed route between the Antelope and Pardee substations, including approximately 13 miles within the Angeles National Forest (ANF). The proposed 500-kV transmission line route traverses an area of residential development in the Santa Clarita Valley area to the north and east of the existing Pardee Substation. The 500-kV transmission line would be energized initially at 220 kV. The proposed project would include electrical interconnections at the existing Antelope and Pardee substations as well as an initial expansion of the Antelope Substation and relocation of several existing 66-kV subtransmission lines in the vicinity of the Antelope Substation (collectively, referred to as the Antelope-Pardee 500-kV Transmission Line Project). The proposed project also includes the acquisition and fencing of approximately 31 acres of land necessary for the upgrade of the Antelope Substation from 220 kV to 500 kV.

Proponent's Environmental Assessment (PEA)

As part of its application to the CPUC, SCE prepared and submitted a Proponent's Environmental Assessment (PEA), which describes the proposed project, existing environmental conditions in the project area, and potential environmental impacts. The December 2004 PEA may be viewed here.

Notice of Preparation and Project Scoping

The CPUC on June 24, 2005, issued a Notice of Preparation of an Environmental Impact Report (EIR) for the Antelope-Pardee 500-kV Transmission Line Project, including a map of the project area. In addition, the Forest Service published a Notice of Intent to prepare an Environmental Impact Statement (EIS) for the proposed project. The CPUC and the Forest Service have agreed to prepare a joint EIR/EIS for the proposed project to satisfy the requirements of CEQA and NEPA.

The CPUC and the Forest Service held two Public Scoping Meetings on June 29 and July 14 to solicit input from the public on potential impacts of the proposed project that should be addressed in the Draft EIR/EIS.

Draft Environmental Impact Report/Environmental Impact Statement

The CPUC and the Forest Service are preparing a Draft EIR/EIS for the proposed project, which is expected to be released for public review in the summer of 2006. The Draft EIR/EIS will be available for review on this website. Additionally, this website will announce the dates and locations for the public meetings on the Draft EIR/EIS.
