Addition of Arsenic Removal Treatment System to Existing Kern Valley State Prison

Document Description
CRCR proposed to construct and operate a groundwater treatment plant at KVSP that would remove arsenic from groundwater. The arsenic removal system will consist of two reaction vessels, chemical injection equipment, backwash recovery equipment and associated valves, piping and controls. A backwash recovery system will be provided to collect spent backwash water, settle out the solids, and return the water back to the front of the arsenic removal system for treatment. The recovery system will consist of two backwash pumps, a 30,000 gallon recovery tank, and two recovery backwash pumps. A new 1,650 square foot water treatment plant building will be constructed next to the prison's existing water storage tanks and booster pumping station. The building will be designed to house chemicals used in the treatment process, filtration system control panel, air compressor, and chemical analyzers. The project includes electrical power and control system upgrades to accommodate the arsenic water treatment process. It is anticipated that construction would start in April 2007 and be completed by December 2007. The ground water treatment system is required to meet new adopted arsenic regulations to reduce maximum contaminant levels for drinking water. Existing staff would be trained to operate the facility.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Section 15301(a), (f)
Reasons for Exemption
The proposed project involves minor, short-term construction to add an arsenic water treatment system and plant treatment building to an existing prison facility. The project involves additions to existing facilities that involve negligible or no permanent effect on the environment. No new water wells would be constructed for the project and there would be no change in existing groundwater uses. No new staff would be required to operate the new arsenic treatment equipment. The project could be characterized as a health and safety project necessary for compliance with State domestic drinking water standards. The project would reduce arsenic levels in the facilities drinking water below state standards and would have a beneficial impact on potable water quality. CEQA Section 15301(f) exempts a project if it adds safety or health protection devices in conjunction with existing structures.
