Draft Supplemental Environmental Impact Report Page VIII-64 Forward Inc.Landfill 2018 Expansion Project Forward has prepared a workplan, which has been submitted to the Water Board, to evaluate the occurrence of VOCs in the Forward Unit monitoring wells. (Forward Unit Evaluation, Monitoring, and Interim Corrective Action Work Plan. GLA,June 2018). Furthermore,to monitor groundwater southeast of the landfill, two additional wells (MW-25 and MW-26)were constructed on the southeast side of the Forward Unit in ' December 2018. Water quality would be monitored in these wells quarterly. If there is evidence of a release, as identified by water quality data in these or other wells monitoring the Forward Unit,the RWQCB would be notified, and further evaluation of the nature and extent of the VOCs will be completed, followed by appropriate corrective measures. The LaForge wells are located about 3,700 feet southeast of the nearest landfill limits. This is a substantial distance from the landfill, with no evidence of a release having occurred to the southeast. Further,the RWQCB has recognized the location of the LaForge wells relative to the landfill and has not recommended sampling of these or other agricultural wells, as they are not designed for water quality monitoring and would not provide representative sample data. New monitoring wells MW-25 and MW- 26 would detect any releases well in advance of a potential impact to the LaForge well such that appropriate mitigations as needed, and with the approval of the CVRWQCB, could be implemented. J-3. As discussed in the Response to Item J-1A,the groundwater extraction system is associated with clean-up of the existing legacy plume from the unlined portions of the Austin Unit. The proposed additional landfill acreage will be lined and the effectiveness of the lined landfill units is discussed in Response Item J-113. J-4. The comment states that the SDEIR looks to the preparation of a hydraulic and drainage study that would culminate in an undefined "project design feature" to control drainage run-on and runoff. The project design is a performance-based design and would conform to the 27 CCR 20365 requirement that all waste management"units and their respective containment be designed and constructed to limit,to the greatest extent possible,ponding, infiltration, inundation, erosion, slope failure,washout, and overtopping."Because the Forward Landfill is a Class II facility, the stormwater design is based on a 1,000-year,24-hr storm as listed in Table 4.1 of the regulation. The stormwater design is required to be presented in the facility's Joint Technical Document (JTD)that must be prepared by and stamped by a California Registered Professional Engineer or Certified Engineering Geologist.The JTD is the permitting document that will be reviewed and approved by both CalRecycle and the CVRWQCB prior to issuing operating permits for the facility. A public review period is required by both CalRecycle and the RWQCB prior to the issuance of operating permits (per 27CCR Division 2, Subdivision 1,Chapter 4,Subchapter 3). In addition,Impact G.1 on Page IV.G-17 of the DSEIR states that the"Site run-on and run-off control facilities consist of drains and perimeter ditches that channel surface water to holding and evaporation ponds on the site. The surface-water collection drain system would be designed to divert the water to the onsite sedimentation basins.All
