Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
15301(b)
Reasons for Exemption
The project involves the continuing operation of an existing wireless facility, with no modifications. Therefore, the project is exempt under CEQA Guidelines, Section 15301(b), regarding "Existing Facilities," which specifies that the continued operation of investor and publicly owned utilities, involving negligible or no expansion of the existing or former use, are categorically exempt from CEQA review. There is no substantial evidence that the project involves unusual circumstances, including future activities, resulting in, or which might reasonably result in, significant impacts which threaten the environment. None of the exceptions in CEQA Guidelines section 15300.2 apply.
