Site Approval No. PA-1900132
Document Type
NOE - Notice of Exemption
Document Description
one-year time extension for a Site Approval granted in September 2020. The original Site Approval was determined to be categorically exempt from CEQA review and a Notice of Exemption was filed and posted in September 2020. For reference purposes only, a description of the Site Approval is provided below. The Site Approval was granted in 2020 for a remotely operated and monitored 25 MW / 100 MWh battery energy storage system (BESS) facility located on approximately 2.2 acres of a 4.76-acre parcel in unincorporated San Joaquin County, adjacent to the city of Stockton. The Project will establish an unmanned, 25-megawatt (MW) battery energy storage system facility utilizing 2.2 acres of a 4.76-acre parcel to include 38 storage containers totaling 12,160 square-feet to house battery storage racks for lithium batteries; 1 auxiliary battery storage container; 16 inverters/transformers totaling 1,920 square-feet to convert between AC and DC and to step up the voltage; and 1 site substation totaling 5,940 square-feet. The Project includes accessory equipment including inverters, switchgear, telecommunications equipment, and an approximately 120-square-foot spare parts enclosure; an ancillary project substation; a 15,000-gallon water tank for fire protection; access roads and parking area, pads for battery cabinets and accessory equipment; underground wires and cabling connecting the batteries to the Project substation; and perimeter fencing. The battery cabinets, accessory equipment, water tank, and project substation are non-habitable, small structures with a total footprint of approximately 20,565 square-feet. A new 60 kV generation interconnection transmission line (gen-tie) on a new, approximately 70-foot-high monopole would connect the BESS to PG&E Weber Substation on the adjacent parcel to the west. Fiber optic cables would also be installed underground to provide a telecommunications connection between the Project site and the PG&E facilities. PG&E would also reconductor approximately one-mile of existing 60-kV power line in the city of Stockton near the Project site, replacing existing conductors and replacing wood support poles with light-duty steel poles at a similar height (40-feet above street level) within the existing alignment.

Notice of Exemption

Exempt Status
Type, Section or Code
General Exemptions. (Section 15061 [b][3])
Reasons for Exemption
This project is exempt from the California Environmental Quality Act (CEQA) per CEQA Guidelines section 15061(b)(3). Section 15061(b)(3) states that “CEQA applies only to projects which have the potential for causing a significant effect on the environment. Where it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment, the activity is not subject to CEQA.” This project provides a one-year time extension to a Site Approval permit for a project that was previously determined to be categorically exempt from CEQA and for which a Notice of Exemption was filed and posted in 2020. The project solely provides an extension of time to implement the Site Approval permit. Other than the extension of time, no other modifications or revisions have been made to the Site Approval Permit. As such, there is no possibility that the project may have a significant effect on the environment and, therefore, the Project is not subject to CEQA.
