Ragaini , Head <br /> Environmental Protection Department <br /> University of California <br /> Lawrence Livermore National Laboratory <br /> RnSt Office °Cx 803 <br /> Livermore, CA 94550 <br /> REPORT OF WASTE DISCHARGE, GROUND WATER TREATMENT SYSTEMS, LAWRENCE LIVERMORE <br /> NATIONAL LABORATORY SITE 300 - CASE NO. 2677 <br /> I have reviewed the 2 February 1990 Report of Waste Discharge (RWD) for the <br /> proposed discharges of treated ground water to land and to Corral Hollow Creek. <br /> In the RWD, Lawrence Livermore National Laboratory (LLNL) proposes to treat the <br /> around water from the Building 334 complex, the General Services Area, the Pit <br /> 5 landfill , and the high explosives process area. The RWD is incomplete because <br /> it does not adequately characterize the site-specific factors relevant to the <br /> disposal of the treated ground water. The required information is specified in <br /> the enclosed Additional dr7formation Requirements and discussed below. Discussions <br /> with EPA staff have determined that LLNL should complete the attached Form 2D <br /> but need not complete Form 3. Before the Board can adopt waste discharge <br /> requirements, LLNL must comply with the California Environmental Quality Act. <br /> The RWD should describe each proposed spray disposal area on detailed maps <br /> portraying, but not limited to, land contours, distance to surface drainage <br /> courses, and locations of proposed and existing extraction and monitoring wells, <br /> ,,,, M..nt .iySt..ms, and ifs TietCi S. The ,v"iYitl should note the type OT treatment <br /> system proposed for each area and include designs of runoff control berms for <br /> the spray disposal areas to ensure no runoff of wastewater. If you propose to <br /> use only lysimeters to detect when runoff is imminent, with no physical controls; <br /> you will have to provide complete calculations showing how the system will work <br /> considering soil characteristics and all other relevant factors. <br /> The RWD should describe the stratigraphy beneath each disposal site and the <br /> depth to ground water. To evaluate the projected performance of the ground <br /> water extraction system, the RWD should present- capture zone analyses, the <br /> projected flow rates from each weII , and other hydraulic testing performed to <br /> plate to evaluate the performance of the proposed extraction wells. <br />
