DECISION ADDRESSING THE SOUTHERN CALIFORNIA EDISON
COMPANY APPLICATION FOR A PERMIT TO CONSTRUCT
THE MASCOT SUBSTATION PROJECT

1. Summary

This decision grants Application 09-11-020 by Southern California Edison Company (SCE) for a permit to construct the proposed project known as the Mascot Substation Project (Proposed Project), pursuant to General Order 131-D, in unincorporated Kings County, California. Approval of this Application allows SCE to construct additional transmission capacity serving the City of Hanford and unincorporated Kings County to ensure that customer electrical demand can be met safely and reliably.

The Proposed Project includes:

1. Construction of a new 66/12 kilovolt (kV) distribution substation.

2. Construction of three new 66 kV subtransmission line segments to serve the new Mascot Substation.

3. Construction of four new 12 kV distribution circuits, and

4. Facilities to connect the new substation to SCE's existing telecommunication system.

As the Lead Agency for environmental review, we find the Final Mitigated Negative Declaration prepared for the Proposed Project meets the requirements of the California Environmental Quality Act.¹

This proceeding is closed.
