Document Description
The proposed improvements include the following:
1. A new PFAS groundwater treatment system to treat raw water from the existing T7, U4 and U6 Wells that will consist of 2 trains of Ion Exchange Vessels (4 vessels total) to be approximately 16 feet in height and 12 feet in diameter, two pre-filter assemblies, above and below-ground raw and treated water piping, drainage, electrical and well pump upgrades.
2. A New VOC groundwater treatment system to treat raw water from the existing Saugus 1 and Saugus 2 Wells that will consist of 2 trains of Granular Activated Carbon (GAC) Vessels (4 vessels total) to be approximately 16 feet in height and 12 feet in diameter, above and below-ground raw and treated water piping, drainage, electrical and well pump upgrades. The scope of work will also include the replacement of a flexible expansion joint within a portion of the well water transmission line on Bouquet Canyon Road, approximately 200 feet south of the RVIPS property.
3. A new disinfection system building(s), including a liquid ammonium sulfate feed system and an on-site sodium hypochlorite generation system, to treat raw water from the existing T7, U4, U6, Q2, Saugus 1 and Saugus 2 wells. The existing chemical storage structures are to be removed once the new disinfection buildings are constructed.
All proposed improvements are to be located on existing Santa Clarita Valley Water Agency property at the Rio Vista Intake Pump Station.

Reasons for Exemption
The Project, aka the whole of the action, qualifies for an exemption under CEQA guidelines section 15301 Class 1 Existing Facilities because it is a minor alteration of an existing public facility and it concerns proposed new mechanical equipment involving negligible or no expansion of use, i.e., no additional extraction of water, beyond that existing at the time of the lead agency’s determination.
