Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
CEQA Guidelines Sections 15302 and Section 15061(b)(3)
Reasons for Exemption
At its September 7, 2023, meeting, the Central San Board of Directors independently found this Project is exempt from the California Environmental Quality Act (CEQA) under Central San's CEQA Guidelines Section 15302, because it involves replacement of existing facilities at substantially the same locations and with the same purpose and level of activity as the facilities being replaced. Any capacity increases are for nongrowth inducing, wet weather purposes. The Project also is exempt under Central San CEQA Guidelines Section 15061(b)(3), since it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment. This certainty is based on Central San's experience with numerous sewer construction projects of this nature, the relatively short distance involved, and Central San's impact-limiting construction specifications. These specifications are standardized general and special conditions that are made part of the project bid documents to address environmental considerations, such as protecting trees and riparian areas, as well as compliance with applicable federal, state, county, district, municipal and local laws, ordinances, orders, and regulations.
