Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
State CEQA Guidelines: § State CEQA Guidelines §15301 and §15302
Reasons for Exemption
State CEQA Guidelines §15301 (Existing Facilities) allows for the operation, repair, maintenance, permitting, leasing, licensing, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features, involving negligible or no expansion of existing or former use. The key consideration is whether the project involves negligible or no expansion of use including existing facilities of both investor and publicly owned utilities used to provide electric power, natural gas, sewerage, or other public utility services. This Project consists of repairing and replacing existing secondary clarifier parts and will require no expansion of use.
State CEQA Guidelines §15302 (Replacement or Reconstruction) Class 2 consists of replacement or reconstruction of existing structures and facilities where the new structure will be located on the same site as the structure replaced and will have substantially the same purpose and capacity as the structure replaced, including the replacement or reconstruction of existing utility systems and/or facilities involving negligible or no expansion of capacity.
