In accordance with the California Environmental Quality Act Guidelines, the West Valley Water District (WVWD) has prepared this notice to inform agencies and interested parties that it is releasing an Initial Study and Proposed Mitigated Negative Declaration (IS/MND) for the Oliver P. Roemer Water Filtration Facility Expansion Project. The proposed Project site is located within the City of Rialto at the existing Oliver P. Roemer Water Filtration Facility (RWFF). All improvements would be confined to this facility with exception of a new 30-inch water pipeline that would extend from the RWFF through open space, to North Linden Drive, to existing water storage reservoirs located at the end of West Via Bello Drive. The Project site is not located on a site enumerated under Section 65962.5 of the Government Code related to hazardous waste disposal.
The WVWD is proposing to expand the RWFF from the current 14.4 mgd to 21.6 mgd to treat additional State Water Project water, and includes the following Project elements: install three new Trident filtration units; replace the existing UV reactors, adjust the Granular Activated Carbon system form series to parallel mode; enhance the Backwash Settling Ponds, install water booster pumps; construct a new influent pump station, install a 30-inch treated water conveyance pipeline from the RWFF to the reservoirs; and repair other existing infrastructure.
A 30-day public review period will extend from August 9 to September 9, 2021. Please email any comments on the IS/MND by 5 PM on September 9, 2021 to Linda Jadeski at email@example.com.
After the review period closes, the WVWD Board of Directors will consider adopting the IS/MND for the project during a public meeting tentatively scheduled for September 16, 2021 at 6:30 PM. We encourage you to check the WVWD’s webpage to confirm the date, time, location and format (live or online) of the Board meeting at the following website address: https://wvwd.org/about/meetings-events/.
