VF in <br /> KLEINFELDER <br /> 2.4 Recycling of Debris <br /> Backhoe trenching revealed that the debris consists of metal, concrete, wood, and pockets of <br /> slaked lime. Metal will be pulled from the excavated debris for later transport to a metals <br /> recycling facility. Concrete will be transported to a temporary onsite crushing plant that will be <br /> processing concrete rubble (primarily from the demolished buildings and storage silos) into <br /> aggregate that will be used in road construction. Lime will be moved to the lime ponds (all the <br /> lime in the lime ponds will be handled in accordance with the Waste Discharge Requirements <br /> (WDRs) for the lime ponds. All labor would be performed by your excavation contractor. <br /> 2.5 Disposal of Remaining Debris <br /> After recyclable materials have been removed from the excavated debris, the remainder will be <br /> transported by your excavation contractor to an offsite landfill for disposal. The landfill that will <br /> be used has not yet been selected although likely candidates are Forward Landfill and Austin <br /> Road Landfill both south of Stockton. <br /> 2.6 Soil Sampling and Testing <br /> If hazardous or unexpected wastes are not uncovered during the debris excavation and staining of <br /> the soils beneath the debris is not present, soil samples will not be collected after the debris has <br /> been excavated. If any of these conditions are encountered, soil samples will be collected. Soil <br /> samples will be analyzed for the following: <br /> • Chlorinated Herbicides by Method SW8150 <br /> • Organophosphorus Pesticides by Method SW8141 <br /> • Semivolatile Organics by Method SW8270 <br /> • Volatile Organics by Method SW8260 <br /> • Inorganics (metals and compounds): <br /> 0 Sb, Ba, Be, Cd, Total Cr, Co, Cu, Ag, Sn, V, Zn, Ni, Mn, by ICP (Method <br /> SW6010) <br /> 0 Pb, Tl by GFAA(Method SW7000) or by ICP (Method SW6010) <br /> 0 Hg by CVAA (Method SW7471) <br /> 0 As, Se by Method SM3114B or by ICP (Method SW6010) <br /> 0 Cyanide by Method SW9012 <br /> 0 Sulfide by Method SW9030 <br /> The soil samples will be submitted to a laboratory certified by the California Department of <br /> Toxic Substances (DTSC) for the requested analyses. After receipt and review of the analytical <br /> results, the excavations will either be immediately backfilled, or further excavation and sampling <br /> conducted, if additional excavation is warranted by the laboratory results. <br /> 20-3978-0I.W36/2017P 117 Page 3 of <br /> © 1997,Kleinfelder,Inc.
