Document Description
The purpose is to maximize beneficial use of digester biogas and reduce emissions of criteria air pollutants and toxic air contaminants from an existing combined heat and power (CHP) source at the Existing Encina Water Pollution Control Facility (EWPCF). The project includes retrofit of existing cogeneration engines with oxidation catalyst emissions controls, construction of new biotowers in the existing blower room, a new 0.99 MW linear generator facility, a new digester biogas conditioning facility, and a new 2 MWh battery storage capacity. The project will deliver a reliable, resilient solution to managing energy resources (power, heat, and biogas) at the EWPCF.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Existing Facilities 15301, Cogeneration at Existing Facilities 15329
Reasons for Exemption
CEQA Guidelines Section 15301 exempts projects that involve negligible expansion of an existing use. The Project would implement low emissions technology at the existing EWPCF; there would be no expansion of biogas production. There would be a minimal increase in building footprint within the EWPCF site for the new linear generator, battery storage, and biogas conditioning facilities. Section 15329 exempts
installation of cogeneration equipment with a capacity of 50 MW or less at existing facilities that result in no net increases in air emissions and comply with air quality laws. The site does not meet any Exceptions under CEQA Guidelines Section 15300.2 See Attachment A for additional Project information and supporting environmental documentation.
