    Southern California Edison - Circle City Substation and Mira Loma-Jefferson 66 kV Subtransmission Line Project

    Background

    The purpose of this Project is to ensure the availability of safe and reliable electrical service and to provide additional capacity to serve long-term forecasted electrical demand requirements in the Electrical Needs Area (ENA), while also maintaining or improving system reliability and providing greater operational flexibility. The ENA includes the cities of Corona and Norco, and the surrounding area of unincorporated Riverside County. The Project would be located in portions of northwestern Riverside County, including the cities of Corona, Eastvale, and Norco; and in portions of San Bernardino County, including the cities of Chino and Ontario.Pursuant to the California Environmental Quality Act (CEQA), the State of California Public Utilities Commission (CPUC) has prepared an Environmental Impact Report (EIR) for the Project identified below. Southern California Edison (SCE), in its CPUC application (A.15-12-007), filed on December 4, 2015, seeks a permit to construct (PTC) the Circle City Substation and Mira Loma-Jefferson 66 kilovolt (kV) Subtransmission Line Project (Project). The Project consists of construction of: a new 66/12 kV substation (Circle City Substation); four new 66 kV subtransmission source lines; and a new 66 kV subtransmission line, which would be a combination of both overhead and underground construction. The Project would also include an upgrade to the Mira Loma Substation, construction of approximately six new underground 12 kV distribution getaways exiting the proposed Circle City Substation, relocation of approximately 1.9 miles of an existing overhead 33 kV distribution line to an underground position, and installation of telecommunication facilities to connect the Project to SCE's existing telecommunications system.

    Environmental Review

    The CPUC has prepared an Environmental Impact Report (EIR) to evaluate SCE's proposal to complete the project, as well as to evaluate a range of alternatives to the Project. The table below lists the dates for milestones that are associated with the review of the Project.
