The wastewater will consist of treated process <br /> waste (ultrafiltration brine reject, reverse osmosis brine <br /> reject, cooling tower blowdown, and boiler blowdown) from the <br /> NCPA plant. Some of the combined wastewater will be injected <br /> into the NCPA STIG #1 well located adjacent to the generating <br /> facility at the City of Lodi White Slough Water Pollution <br /> Control Facility (WSWPCF) . <br /> The source of the incoming process water for the NCPA <br /> generating facility will be the effluent from the WSWPCF. The <br /> balance of the NCPA wastewater not injected into STIG #1 will <br /> be returned to the WSWPCF for disposal in accordance with its <br /> National Pollutant Discharge Elimination System (NPDES) <br /> permit, No. CA0079243 . 98 percent of the-waste water will be <br /> the brine reject from the ultrafiltration units, brine from <br /> reverse osmosis units, and blowdown from the cooling towers. <br /> The remaining 2 percent of liquid waste intended for injection <br /> will be both continuous and intermittent blowdown from the <br /> Heat Recovery Boilers. <br /> STIG #1 is expected to operate for the 30-year anticipated <br /> lifetime of the NCPA generating plant. <br /> 1 <br />
