Background

PG&E has filed an application with the CPUC to build a new three-bank 230/21 kV distribution substation on a 5.1-acre site in the City of Antioch. In addition, the Proposed Project would include a new transmission tower in an existing transmission right of way and a new paved access road from the intersection of Heidorn Ranch Road and Sand Creek Road to the proposed substation site. The temporary access road would require a temporary steel deck-plate bridge over Sand Creek. PG&E's project objective is to improve reliability and meet projected electrical load requirements in the Delta Distribution Planning Area (DPA), which includes the rapidly growing southern and eastern portion of Antioch, the cities of Brentwood and Oakley, and much of the remainder of unincorporated eastern Contra Costa County.

Proponent's Environmental Assessment (PEA)

PG&E filed a PEA with the Application in August 2005. This document provided a starting point for the environmental review process conducted by the CPUC.

Environmental Review Process

The CPUC on September 22, 2006, released a Notice of Intent to Adopt a Mitigated Negative Declaration (MND) for the Delta Substation Project, showing that the Proposed Project, as mitigated, would not have any significant effects on the environment. Public comments on the MND were accepted for 30 days until October 23, 2006. The CPUC on November 28, 2006 released a Final MND incorporating responses to the public comments.

In addition to the electronic version at the link above, the MND may also be reviewed at the Antioch Library (501 West 18th Street, Antioch), the Brentwood Library (751 Third Street, Brentwood), and the CPUC (505 Van Ness Ave, San Francisco)

The CPUC will issue a Decision on the Proposed Project as part of the proceeding on A.05-08-022, which will be announced and published concurrent with a scheduled CPUC meeting.
