WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2008-0148 -16- <br /> LAWRENCE LIVERMORE NATIONAL SECURITY, LLC AND <br /> THE U.S. DEPARTMENT OF ENERGY FOR <br /> LAWRENCE LIVERMORE NATIONAL LABORATORY SITE 300 <br /> SAN JOAQUIN AND ALAMEDA COUNTIES <br /> and 100 feet for drinking water supply wells, groundwater within 50 feet of the <br /> septic systems is not available for agricultural, municipal, or domestic use. <br /> 68.The Discharger has not evaluated the potential for domestic wastewater <br /> discharges to the septic systems to impact beneficial uses of groundwater. <br /> Also, the Discharger does not monitor the groundwater specifically for impact <br /> of discharges from septic systems to groundwater; however, groundwater <br /> monitoring wells installed for the CERCLA investigations exist in the general <br /> vicinity of most of the septic systems. The Discharger monitors for a wide <br /> range of constituents associated with the CERCLA project. CERCLA <br /> investigations in the areas around Building 812, Building 834, Building 850, <br /> and Building 899, have determined that nitrate concentrations in groundwater <br /> exceed the drinking water MCL. Investigations in these areas have attributed <br /> the source of the nitrate at least in part to the septic systems. This Order <br /> requires the Discharger to monitor existing groundwater monitoring wells in <br /> the vicinity of these four septic systems as described in the MRP. <br /> 69.This Order requires the Discharger to evaluate if groundwater is impacted or <br /> may be impacted by the septic systems, as described below in Provision 8. If <br /> any septic systems have degraded groundwater, the Discharger will be <br /> required to monitor groundwater up and downgradient of those septic <br /> systems and to submit a feasibility study proposing remedial alternatives to <br /> restore beneficial uses of groundwater if it is determined by the Regional <br /> Water Board that the groundwater has been unreasonably degraded. The <br /> Discharger shall include a proposal for implementing a source control <br /> program and BPT to reduce pollutants in the discharge. <br /> Low Threat Discharges <br /> 70.The Discharger conducts a variety of activities at Site 300 that may result in <br /> low volume and low-threat discharges. Consistent with the Storm Water <br /> Pollution Prevention Program, the discharger has implemented Best <br /> Management Practices (BMPs) to prevent these discharges from reaching <br /> surface water drainage courses, thus these discharges percolate into the <br /> ground. The discharges detailed in Attachment 4 are primarily composed of <br /> potable water, low conductivity water, condensate, and uncontaminated <br /> contained rainwater. These discharges may occur at any of the facilities and <br /> outdoor areas at Site 300. <br /> 71.The Discharger evaluated the low threat discharges in a technical report <br /> submitted in 1994. These discharges did not contain any constituents that <br /> would negatively affect groundwater and are discharged in low volumes, <br />
