Bringing Lithium Sulfur Technology to Market
Document Type
NOE - Notice of Exemption
Document Description
The purpose of this project is to conduct design and testing of lithium-sulfur battery cells and modules and install a interconnected field-prototype system with a utility-scale microgrid at University of California, San Diego. The majority of the proposed project are laboratory work, modeling, design and engineering, and other activities that do not require permitting by outside agencies or which will take place under existing building permits and use codes at locations already occupied and utilized by project team. Installation, commission, and operation of the prototype system will require permitting and UCSD is a self-permitting entity as the Authority Having Jurisdiction. Notice of Exemption is estimated to be issue two weeks following submission request and supporting documentation, such as final construction plans as approved, by the UCSD Fire Marshal and Electrical and Civil permitting staff.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Cal. Code Regs., tit. 14, § 15301
Reasons for Exemption
This project will (1) design and test lithium-sulfur battery cells and modules and (2) install an approximately 150 kW interconnected field-prototype battery module system at an existing microgrid at University of California, San Diego (UCSD). The majority of the project work, which includes modeling, design, engineering and testing of the battery cells and modules, will be conducted in an existing laboratory at UCSD. The project will not involve any construction activities. Minor modifications to existing facilities to connect the battery module system to the existing electrical transformer. The system will operate for a minimum of 12 months at a medium voltage (12kV) distribution level. This project is therefore categorically exempt from environmental review pursuant to CEQA Guidelines section 15301 as minor alterations to existing facilities that involve negligible or no expansion of an existing or former use at the sites.

Exempt Status
Categorical Exemption
Type, Section or Code
Cal. Code Regs., tit. 14, § 15303
Reasons for Exemption
The project is also categorically exempt pursuant to CEQA Guidelines section 15303 as the installation of small new equipment in small structures. The project does not involve any unusual circumstances, will not result in damage to any scenic resources within a highway officially designated as a state scenic highway, none of the installation sites are included on any list compiled pursuant to Government Code section 65962.5, and the project will not cause a substantial adverse change in the significance of a historical resource. Therefore, none of the exceptions to exemptions listed in CEQA Guidelines section 15300.2 apply to this project and the project, when considered as a whole, will not result in a cumulative impact that is significant on the environment.
