Introduction

Welcome to the California Public Utilities Commission (CPUC) website for the California Environmental Quality Act (CEQA) review of proposed construction of the Mesa 500-kV Substation Project (Mesa Substation Project). On March 13, 2015, SCE filed an application [Application No. A.15-03-003] for a Permit to Construct (PTC) with the CPUC to rebuild and upgrade a portion of its transmission infrastructure primarily within the Western Los Angeles Basin Electrical Needs Area. The majority of work will take place in the City of Monterey Park with some work occurring in nearby cities and portions of unincorporated Los Angeles County. In accordance with CEQA, the CPUC, as the Lead Agency, is preparing an Environmental Impact Report to evaluate the Proposed Project. This site provides access to public documents and information relevant to the CEQA review process.
