Document Type
NOE - Notice of Exemption
Document Description
The Royale-Yorkshire Substation Upgrade Project (Project) consists of replacing an aging 20-megavolt-ampere (MVA) transformer located adjacent to the south side perimeter wall. A new 25-MVA transformer will be placed in the same location along with other associated infrastructure including switchgear, two new pullboxes, a new battery enclosure foundation, and lines and equipment required to interconnect with the existing 69kV/12kV system. The existing equipment will be removed from the substation. Surface excavation will be required for the removal and reconstruction of the new transformer and switchgear concrete foundation pad with a surrounding sub-grade oil containment area. The Project will also include modification and/or replacement of support infrastructure (i.e. switch pole, tap pole, pull box, conduit, grounding, etc.) to service the new transformer and switchgear. Other substation upgrades include repaving the existing driveway that has been damaged by tree roots, widening and replacing the existing chain-link gate with a metal swing gate, and installing an additional metal gate along the southern perimeter wall.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
CCR 14, Sections 15301 and 15302
Reasons for Exemption
SMUD has reviewed and determined that the Project is categorically exempt from the provisions of CEQA pursuant to Sections 15301 (Existing Facilities) and 15302 (Replacement and Reconstruction). Section 15301 applies to projects that consists of the operation, repair, maintenance, permitting, leasing, licensing, or minor alternations of existing public or private structures, facilities, mechanical equipment, or topographical features, involving negligible or no expansion of use beyond that existing at the time of the lead agency’s determination. Section 15302 states that "Class 2 consists of replacement or reconstruction of existing structures and facilities where the new structure will be located on the same site as the structure replaced and will have substantially the same purpose and capacity as the structure replaced..." Thus, the Project will involve the repair and minor alternation of an existing substation facility resulting in no change or expansion of use; and the replacement of an existing transformer in the same location and serving the same purpose and capacity. Therefore, no further environmental review is required.
