Public hearing for Surface Water Treatment Plant Improvement Project on April 16, 2026.

KNIGHTS FERRY COMMUNITY SERVICES DISTRICT


NOTICE OF INTENT TO ADOPT A MITIGATED NEGATIVE DECLARATION
FOR THE SURFACE WATER TREATMENT PLANT IMPROVEMENT PROJECT
 
NOTICE IS HEREBY GIVEN that Knights Ferry Community Services District (District) intends to adopt an Initial Study/Mitigated Negative Declaration ("IS/MND") for the Surface Water Treatment Plant Improvement Project ("Project"). A public hearing to consider adoption of the IS/MND will be held at the District Office, 17631 Sonora Road, Knights Ferry, CA 95361, on Thursday, April 16, 2026, at 9:30 am.  
The Project proposes to construct improvements and/or replace existing infrastructure at the Knights Ferry SWTP. The Project proposes to add a package style water filtration system that includes an up-flow adsorption clarifier adjacent to a mixed media filter, such as the Tri-Mite Package Water Treatment Plant (Tri-Mite) system. The Tri-Mite treatment technology has been demonstrated to satisfy the operational and performance requirements necessary to be accepted as an alternative filtration technology under the California Surface Water Treatment Rule (CSWTR), in CCR, Title 22, Section 64665 (CCR, 2000). 
The Project would include installation of the Tri-Mite treatment system as well as a pumping station to allow sufficient flow among the treatment system and for adequate storage to meet maximum day demand and fire flow. The existing 30,000-gallon storage tank onsite, which has been inoperable, would be demolished as part of the Project. With installation of the Tri-Mite system, the existing flocculation and sedimentation, chlorine contact tanks, and existing multi-media filters would no longer be necessary and would be demolished as well. Other improvements would include site modifications for safety and efficient operations such as parking and onsite security measures with lighting as needed. 
The Project includes the following project components: Installation of the Tri-Mite packaged filter system consisting of one (1) 80-gallons per minute (gpm) unit, a transfer pumping station, cleaning and recoating of the existing 110,000-gallon storage tank, installations of 100,000-gallon storage tank (for finished water), construction of a chemical storage and filter building, a high service pumping station, a backwash pumping station, demolition of the existing 30,000-gallon finished water storage tank, demolition of the existing flocculation and sedimentation tanks, demolition of the existing chlorine contact tanks, demolition of the existing multi-media filters, and disposal of disconnected water treatment infrastructure (i.e., the abandoned clarifier).
Pursuant to the California Environmental Quality Act, an IS/MND has been prepared evaluating the potential environmental impacts of the Project. The District has determined that potentially significant environmental impacts can be reduced to less than significant level with implementation of identified mitigation measures.  
Copies of the IS/MND are available for public review upon written request to the District at 17631 Sonora Road, Knights Ferry, CA 95361. The public review period during which the District will receive comments on the proposed IS/MND begins February 20, 2026, and ends March 23, 2026. Comments should be in writing, and addressed to Ryan McKelvey at Provost & Pritchard, 455 W. Fir Ave, Clovis CA 93611, or email to rmckelvey@ppeng.com.
   
The Project site has been reviewed in accordance with Government Code Section 65962.5 and is not listed as a hazardous waste or materials site.
