Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
15301(b) and 15303(e)
Reasons for Exemption
The State CEQA Guidelines provide a series of categorical exemptions for projects that have been deemed to have minimal impacts on the environment. The proposed project consists of installing an IX water treatment system at the District’s MN Plant #2 located in the City of Riverside. Based on an analysis of the proposed project, the District has determined that it has no potential to cause significant adverse effects on the environment and will allow the District to continue delivery of potable water to their customers without significant adverse impact. Categorical Exemption Class 1 exempts “the operation, repair, maintenance, permitting, leasing, licensing, or minor alteration of existing public or private structures, facilities, mechanical equipment...involving negligible or no expansion of use beyond that existing at the time of the lead agency’s determination. (b) Existing facilities of both investor and publicly owned utilities used to provide electric power, natural gas, sewerage, or other public utility services.....(f) Addition of safety or health protection devices for use during construction of or in conjunction with existing structures and facilities, or mechanical equipment...” and Categorical Exemption Class 3 exempts “construction and location of limited numbers of new, small facilities or structures; installation of small new equipment and facilities in small structures...(e) accessory (appurtenant) structures including garages, carports, patios, swimming pools and fences.” The exceptions to the issuance of Categorical Exemptions have been evaluated for the proposed project, and the proposed project has been determined not to have a potential to cause significant adverse environmental effects as a result of any of the exceptions. Therefore, this proposed action is not forecast to cause any potential for significant adverse environmental impacts and qualifies with the requirements for both Class 1 and Class 3 Exemptions.
