Welcome to the California Public Utilities Commission (CPUC) website
for the California Southern California Edison's (SCE) proposed Riverway
Substation Project (Riverway Substation). An application for this
project was submitted to the CPUC on June 1, 2006 (A.06-06-004).
This site provides access to public documents and information relevant
to the CEQA review process.
Background
SCE has filed an application with the CPUC to build a new 1.7-acre
66/12 kV low-profile substation with two 28 MVA transformers and
six 12 kV distribution lines. The project would include approximately
1,200 feet of underground 66 kV subtransmission lines, as well as
new fiber optic cable and communication equipment to connect the
substation to SCE's existing telecommunication system. The substation
site is located north of Riggin Avenue and east of Mooney Boulevard
(which is being extended north of Riggin Avenue) in the City of
Visalia.
SCE has stated that the project is necessary to maintain safe and
reliable service and meet projected electrical load requirements
in the City of Visalia and northern Tulare County. The substation
would be constructed to accommodate future capacity increases beyond
2010, as required.
Proponent's Environmental Assessment
(PEA)
SCE filed a PEA with the Application
in June 2006. This document provided a starting point for the environmental
review process conducted by the CPUC.
Environmental Review Process
On May 31, 2007, the CPUC released a Notice of Intent to Adopt
a Mitigated Negative Declaration (MND)
for the Riverway Substation Project, showing that the Proposed Project,
as mitigated, would not have any significant effects on the environment.
Public comments on the Draft MND were accepted for 30 days until
June 30, 2007, and on July 26, 2007, the CPUC released
the Final MND incorporating responses to the public comments.
On September 6, 2007, the CPUC granted a Permit
to Construct for the project.
Construction of the project began on October 29, 2007, after a
Notice to Proceed with Construction was granted by CPUC on October
16, 2007. A CPUC Environmental Monitor is monitoring construction
activities to ensure that they are conducted in accordance with
the approved mitigation measures and permit conditions. This site
holds all weekly reports documenting this
monitoring activity
