Derrick Peterson, Esq. = <br /> 3709 Toro Canyon Road <br /> Austin, Texas 78746 <br /> REPORT OF WASTE DISCHARGE,KEARNEYKPF, STOCKTON, SAN JOAQUIN <br /> COUNTY <br /> We have reviewed the Report of Waste Discharge(ROWD) submitted on 11 December 2000 by <br /> Dudek&Associates,Inc. (Dudek) on behalf of Kearney-National, Inc. (Kearney) for the <br /> proposed discharge of treated groundwater at the Kearney-KPF facility, 1624 East Alpine <br /> Avenue, Stockton(site). The application is complete, and Board staff will draft revisions to your <br /> waste discharge requirements to include effluent standards for 1,4-dioxane. <br /> Kearney operated a groundwater extraction and treatment system designed to remove volatile <br /> organic compounds (VOCs) from groundwater between January 1993 and October 1998. <br /> Kearney treated the extracted, contaminated groundwater by air stripping and granular activated <br /> carbon, and injecting the treated effluent back into the subsurface. However,the treatment <br /> method was not designed to remove 1,4-dioxane,a compound that was not tested for until 1997. <br /> In October of 1998 Kearney, therefore,ceased operation of its groundwater extraction and <br /> treatment system to prevent re-injection of 1,4-dioxane contaminated groundwater. This ROWD <br /> addresses treatment for 1,4-dioxane in the extracted groundwater prior to injection. <br /> Kearney may install and operate the proposed remediation system under existing Waste <br /> Discharge Requirements (WDR) Order No. 91-220, on the condition that Kearny has agreed to <br /> operate the system as long as the effluent meets a monthly average 1,4-dioxane concentration of <br /> 2 µg/1 and a daily maximum concentration of 4 µg/1. We understand Kearny has agreed to shut <br /> down the system in the case these limits cannot be met. In addition,the treatment system <br /> effluent will need to also be analyzed for 1,4-dioxane with a maximum reporting limit of 1 µg11. <br /> Once the new treatment system is installed, Kearney needs to collect samples from the <br /> groundwater influent,the treated water exiting the lead treatment vessel, and the treated water <br /> exiting each subsequent treatment vessel according to the following schedule: <br /> a. At system startup <br /> b. After one, four, and twelve hours of operation from the groundwater influent and after <br /> exiting the final treatment vessel <br /> c. After 24 hours of operation <br /> California Environmental Protection Agency <br /> 0 Recycled Paper <br /> The energy challenge facing California is real.
