DRAFT [TENTATIVE] WASTE DISCHARGE REQUIREMENTS ORDER R5-2023-00XX 22 FORWARD, INC. FORWARD LANDFILL SAN JOAQUIN COUNTY indicate that there was not a significant release to the environment. The Discharger pursued the option to reconstruct the entire WMU F West. Central Valley Water Board staff concurred with the Second Revision to WMU F-West EMP and CAP Report in a letter dated 10 May 2023. 68.The groundwater extraction system consists of five groundwater extraction wells at the downgradient boundary of the former Austin Road Unit and one groundwater extraction well on the CDCR property, located approximately 1,900 feet north of the landfill. These wells are identified as EW-1, EW-2, EW-3R, EW- 4, and EW-5 on the Austin Road Unit and CDCR-EW-1 on the CDCR property. VOCs were removed with an air stripper until May 2018. 69.The extracted groundwater is currently treated by two 10,000-pound granular active carbon (GAC) vessels that were installed in January 2020. The treated water is discharged to a recharge basin to recharge the shallow aquifer. Discharges from the groundwater extraction system are regulated by WDR Order R5-2003-0080 for the discharge of treated groundwater. Unit Construction 70.Liners for new Class II WMUs (landfills and surface impoundments) must be designed and constructed to contain fluids (e.g., leachate, waste, and LFG condensate) to prevent the migration of waste to adjacent geologic materials, groundwater, and surface water (see Title 27, section 20310 subd. (a), 20330 subd. (a)). 71.Liners for new Class III WMUs (landfills) must be designed and constructed to contain fluids (e.g., leachate, waste, and LFG condensate) so as to be capable of preventing degradation of groundwater and surface water, even with inadequate site characteristics (see Title 27, secs. 20310, subd. (c), and 20330, subd. (a)). 72.General water quality monitoring and system requirements (Title 27, sec. 20415, subd. (e)(6)) require initial background sampling for each unit. At minimum, the Discharger needs to collect analytical data obtained during the quarterly sampling of all the Background Monitoring Points for a period of one year. For a new unit, this data shall be collected before waste is discharged at the unit and background soil-pore liquid data shall be collected from beneath the unit before the unit is constructed. 73.Unless otherwise specified in Title 27, division 2, subdivision 1, the Central Valley Water Board may approve an engineered alternative to the State Water Board- promulgated construction and prescriptive standards therein, provided that the Discharger demonstrates that the standard is not feasible and there is a specific engineered alternative that is consistent with the performance goal addressed by the particular standard and affords equivalent protection against water quality
