DRAFT [TENTATIVE] WASTE DISCHARGE REQUIREMENTS ORDER R5-2023-OOXX 11 <br /> FORWARD, INC. <br /> FORWARD LANDFILL <br /> SAN JOAQUIN COUNTY <br /> 24. In 1991, the Discharger accepted soils contaminated with less than hazardous <br /> levels of petroleum hydrocarbons. These soils were either treated in the land <br /> treatment unit or discharged to Class II landfill units. The Discharger <br /> demonstrated that soil contaminated with less than hazardous levels of <br /> petroleum hydrocarbons can be transformed to a `nonhazardous solid waste' in <br /> the treatment unit. There are currently no active soil Land Treatment Units <br /> (LTUs) at the site. Soil LTUs are no longer permitted on the site. <br /> Alternative Daily Cover/ Intermediate Cover <br /> (Operating Landfill Units) <br /> 25. In lieu of the daily cover required per Title 27 section 20680, the Discharger <br /> proposes to use an approved alternative daily cover (ADC) (see Title 27, <br /> sections 20690 and 20705), which consists of nonhazardous ash and cement kiln <br /> dust, pre-processed treated auto shredder waste, pre-processed construction <br /> and demolition (C&D) waste, shredded tires, compostable materials (off- <br /> specification and delivered by generator), processed green material, and <br /> geosynthetic tarps. <br /> 26. In accordance with Title 27 section 20705, Discharger has demonstrated that its <br /> proposed ADC materials: (a) will minimize percolation of liquids through waste <br /> and are (b) consistent with the classification of the WMUs to which they are to be <br /> applied. The approved ADC material constituents and breakdown products are <br /> also included as part of the WQPS set forth in the MRP. <br /> 27. The materials approved for use as ADC are as follows: <br /> a. Nonhazardous ash and cement kiln dust <br /> b. Pre-processed treated auto shredder waste <br /> C. Pre-processed construction and demolition waste <br /> d. Shredded tires <br /> e. Compostable materials <br /> f. Processed green materials <br /> g. Geosynthetic tarps <br /> 28. The proposed ADC has already been approved by the Local Enforcement <br /> Agency (LEA). Central Valley Water Board concurs that the proposed ADC <br /> meets applicable requirements in accordance with Title 27 section 20690 subdiv. <br /> (b) and section 20705. <br />
