Reasons for Exemption
State CEQA Guidelines §15301 (Existing Facilities) allows for additions to existing structures. Per §15301, Class 1 consists of 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.
CEQA Guideline §15302 (Replacement or Reconstruction) defines a Class 2 exemption which allows for the replacement or reconstruction of existing structures or 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.
State CEQA Guidelines §15303 (New Construction and Conversion of Small Structures) defines a Class 3 exemption, which consists of construction and location of limited numbers of new, small facilities or structures; installation of small new equipment and facilities in small structures; and the conversion of existing small structures from one use to another where only minor modifications are made in the exterior of the structure. The numbers of structures described in this section are the maximum allowable on any legal parcel.
Exceptions under State CEQA Guidelines §15300.2 do not apply to the project. There are no designated state scenic highways within the project area. The project site is not known to be a hazardous waste site. According to the State Water Resources Control Board GeoTracker data management system, the project site is not included on a list compiled pursuant to Government Code Section 65962.5. No negative environmental consequences associated with hazardous materials are expected to result from project implementation.
This water tank project is exempt from further environmental review because it consists of limited construction and operation of one domestic water reservoir and accessory structures on a previously developed parcel.
