Box 3006 <br /> Lodi, CA 95241 <br /> COMMENTS ON CEQA DOCUMENT TYPE (SCH PROJECT NO. 201012035), CITY OF <br /> LODI, WHITE SLOUGH WATER POLLUTION CONTROL FACILITY(WPCF), SAN JOAQUIN <br /> COUNTY <br /> Pursuant to San Joaquin County Community Development Department's 17 January 2017 <br /> request, Central Valley Regional Water Quality Control Board (Central Valley Water Board) staff <br /> has reviewed the Initial Study/Mitigated Negative Declaration for the subject project. The <br /> Central Valley Water Board is responsible for protecting the quality of surface and ground <br /> waters of the state; therefore, our comments will address water quality matters only. <br /> The applicant proposes to construct a 70-acre Expansion Pond and associated conveyance <br /> infrastructure at the existing City-owned White Slough WPCF. The Expansion Pond will consist <br /> of four individual ponds with an overall storage capacity of up to 388 acre-feet. The Expansion <br /> Pond will be used exclusively to store disinfected, tertiary-treated effluent produced by the <br /> WPCF for use as irrigation water on the 886.67 acres of agricultural land that surrounds the <br /> WPCF. The purpose of the project is to provide additional WPCF effluent supplies for <br /> agricultural irrigation on the agricultural land and to offset groundwater pumping. <br /> The City intends to divert filtered, disinfected recycled water to the new storage ponds. The <br /> diversion facilities that direct treated effluent to the existing storage ponds convey undisinfected <br /> secondary-treated water. Therefore, the project will include new facilities that allow for diversion <br /> of tertiary flows separately from the existing effluent diversion facilities. The project will also <br /> include conveyance infrastructure to provide for delivery of the treated effluent from the new <br /> storage ponds to the City's existing irrigation water delivery system. From this location, the <br /> WPCF's existing irrigation distribution system can deliver this water to various City-owned <br /> agricultural fields. <br /> Waste Discharge Requirements (WDRs) <br /> The discharge of recycled water means water which, as a result of treatment of waste, is <br /> suitable for a direct beneficial use or a controlled use that would not otherwise occur and is <br /> therefore considered a valuable resource. The discharge is subject to regulation under Water <br /> Reclamation Requirements (WRRs) for Recycled Water Use (2016-0068-DDW) (General <br /> Order), adopted on 7 June 2016. The discharge under the General Order is limited to treated <br /> municipal wastewater for uses consistent with the Uniform Statewide Recycling Criteria, and <br /> other uses approved by the State Water Board on a case-by-case basis, other than direct or <br /> indirect potable uses. <br /> KARL E.
