Draft Supplemental Environmental Impact Report Page II-26 Forward Inc. Landfill 2018 Expansion Project F.3. Groundwater Proposed as Part of the Project. Less than contamination would Significant result if the leachate A double liner would be installed under the sump area, as previously collection systems for the required by the RWQCB; expansion areas fail. • The liner and leachate collection system for the two new expansion areas would have new a leachate management system.The adequacy of the leachate collection system and associated monitoring would be reviewed and approved by the RWQCB; • The regulatory required separation between the liner and groundwater shall be implemented to allow for chemicals in the leachate to attenuate before reaching the groundwater, should the leachate breach the liner and leachate collection system; • Electric testing of the liner in each WMU shall be conducted before waste can be disposed in that Unit, as required by the RWQCB; • If any modifications to the leachate collection system and associated monitoring are required by the RWQCB, the landfill operator shall implement those changes; • The liner system will be overlain by a protective operations layer consisting of a one-foot thickness of soil and a one-foot thick gravel layer that serves as the leachate collection layer. This two-foot layer will serve to protect the liner system from sharp or jagged materials in the waste. • The operator will remove any hazardous materials spotted during delivery, thus minimizing the potential for leachate impacts to groundwater if a break occurs in the liner or the leachate collection system. • Landfill operations and maintenance are designed with adequate lifetimes to identify and correct any failures in the leachate collections stem.
