Welcome to the California Public Utilities Commission (CPUC) website for the California Environmental Quality Act (CEQA) review of the proposed construction of Southern California Edison's (SCE) Viejo System Project. An application for this project was submitted to the CPUC on March 21, 2003 (Application A.03-03-043), and the project was approved by the CPUC on July 8, 2004, in Decision D.04-07-027. Construction of the SCE Viejo System Project was completed in March 2006. This site provides access to public documents and information relevant to the CEQA review.
The purpose of the Viejo System Project is to improve reliability and
meet projected electrical load requirements in the rapidly urbanizing
south Orange County area. SCE constructed a 220/66/12 kilovolt (kV) substation
(Viejo Substation) on a 12.5-acre site located in the City of Lake Forest
and a 3.1-mile 66 kV subtransmission line along the corridor between the
proposed Viejo Substation and the existing Chiquita Substation located

In accordance with Public Utilities Code Section 1001, SCE received a Permit to Construct from the CPUC on July 8, 2004.
