NOE - Notice of Exemption
Document Description
Under grant agreement EPC-21-039, the California Energy Commission (CEC) will provide a grant of $3,000,000 grant to Solid Energies Inc. to develop and integrate a new class of all-solid-state Lithium-ion battery cells with higher power density and better manufacturability for electric vehicle and stationary storage applications. This battery achieves these advantages with a combination of a novel polymer-composite based solid-state electrolyte, innovative composite electrodes, and a silicon based composite anode.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Cal. Code Regs., tit. 14, § 15306; Cal. Code Regs., tit. 14, § 15301
Reasons for Exemption
Cal. Code Regs., tit. 14 Section 15306 provides that projects which consist of basic data collection, research, experimental management, and resource evaluation activities, and which do not result in a serious or major disturbance to an environmental resource are categorically exempt from the provisions of the California Environmental Quality Act. Under this grant, first, the technology will be designed and built using a low-rate production line in a building zoned for this activity. Second, the technology will be demonstrated at two existing facilities. There are no sensitive environmental resources at the demonstration sites. For these reasons, the proposed work will not have any significant effect on the environment and is exempt under Cal. Code Regs., tit 14, Section 15306. The CEQA exemption under California Code of Regulations, title 14, section 15301, “Existing Buildings,” applies. Section 15301 covers the operation, maintenance, or minor alteration of existing public or private structures, facilities, mechanical equipment, involving negligible or no expansion of existing or former use. The technology will be manufactured at an existing, permitted facility. The batteries will be tested at existing facilities. This involves negligible or no expansion of existing or former use. The project does not involve any cumulative impacts of successive projects of the same type in the same place that might be considered significant; does not involve unusual circumstances that might have a significant effect on the environment; will not result in damage to scenic resources within a highway officially designated as a state scenic highway; the project site is not 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 categorical exemptions listed in CEQA Guidelines section 15300.2 apply to this project, and this project will not have a significant effect on the environment.
