C7 <br />April 8, 2014 <br />The operator will remove any hazardous materials spotted during delivery, <br />thus minimizing the potential for leachate contamination if a break occurs <br />in the liner or the leachate collection system. <br />A double liner shall be installed under the sump area, as required by the <br />RWQCB; <br />Electric testing of the liner in each Waste Management Unit shall be <br />conducted before waste can be disposed in that Unit, as required by the <br />RWQCB; and <br />Current Status: The liner and LCRS are being designed and constructed as <br />discussed above and in accordance with the JTD. The required separation <br />from groundwater is being maintained. Liner and LCRS designs are <br />submitted to the RWQCB for approval prior to construction. Electric testing <br />of the liner has been performed in the latest cell to be constructed at the site. <br />Hazardous materials are removed in accordance with Forward's load <br />checking program. <br />Identified in EIR: <br />If any modifications to the leachate collection system and associated <br />monitoring described in the JTD are required by the RWQCB, the landfill <br />operator shall implement those changes. <br />Current Status: The RWQCB has not requested any modifications to the <br />leachate collection system as described in the JTD. However, Forward will <br />implement any potential future changes required by the RWQCB. <br />e. 47 (F.4) <br />Proposed as Part of the Project: <br />Proposed measures to address concerns about additional leachate <br />generation as a result of the combined landfill have been addressed in the <br />JTD with the presentation of the EPA HELP model results based on the <br />projected volumes of refuse, and the description of the leachate collection <br />system designed to meet the maximum probable leachate generated. <br />Engineering control systems (leachate collection system, drainage control, <br />groundwater and gas controls), monitoring programs, and institutional <br />controls have been presented in the JTD currently under review at the <br />RWQCB. Reporting on leachate generation volume and quality is a <br />requirement of the RWQCB-stipulated progress reporting through the <br />various proposed landfilling phases. <br />The landfill cell anchor -trenches -will -be elevated two -to three feet above <br />the surrounding land to minimize the possibility of water from major storm <br />events draining into the cells and adding to the volume of leachate. <br />Page 26 <br />
