Reasons for Exemption
Cal. Code Regs., tit. 14, § 15301: A project that consists of 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 is categorically exempt from CEQA. This project involves the system design, optimization, and integration of a
mobile liquid hydrogen refueler that will all take place in existing research facilities. The mobile refueler will then be
demonstrated for a short period of time at an existing airport already used for refueling aircraft and negligible expansion
of existing use is expected. Therefore, this project is categorically exempt from CEQA.
This proposed project does not impact an environmental resource of hazardous or critical concern where designated,
precisely mapped, and officially adopted pursuant to law by federal, state, or local agencies; 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.
