1 <br /> ARCADIS SOP: Investigation-Derived Waste Handling and Storage 12 , <br /> Rev.#:2 1 Rev Date: March 6,20D9 <br /> specific vendor should be consulted concerning specific requirements for <br /> retuming tanks. ' <br /> • Tank Inspection:After emptying the tank, purged water storage tanks should <br /> be inspected for debris,chemical staining,and physical damage.The vendors <br /> require that tanks be returned in the original condition(i.e.,free of sediment, <br /> staining and no physical damage). <br /> VII. Waste Characterization Sampling and Shipping <br /> Soil/Solids Characterization <br /> Waste characterization will be conducted in accordance with waste hauler,waste <br /> handling facility, and state/federal requirements. In general, RCRA hazardous wastes <br /> are those solid wastes determined by a Toxicity Characteristic Leaching Procedure <br /> (TCLP)test or to contain levels of certain toxic metals, pesticides,or other organic <br /> chemicals above specific federally regulated thresholds. If the one or more of 40 toxic <br /> compounds listed in Table I of 40 CFR§261.24 are detected in the sample at levels <br /> above the maximum unregulated concentrations,the waste must be characterized as <br /> a toxic hazardous waste.Wastes can also be considered'listed"hazardous waste <br /> depending on site-specific processes. ' <br /> Composite soil samples will be collected at a frequency of one sample per 10 cubic <br /> yard basis for stockpiled soil or one per 55-gallon drum for containerized.A four point <br /> composite sample will be collected per 10 cubic yards of stockpiled material and for <br /> each drum. Sample and composite frequencies may be adjusted in accordance with <br /> the waste handling facility's requirements.Waste characterization samples may be , <br /> analyzed for the TCLP volatile organic compounds(VOCs),TCLP semi-volatile <br /> organic compounds(SVOCs),TCLP RCRA metals,and polychlorinated biphenyls,as <br /> well as corrosivity(pH), reactivity and flammability(flashpoint).Additional samples may <br /> be collected and analyzed by the laboratory on a contingency basis. <br /> Wastewater Characterization ' <br /> Waste characterization will be conducted in accordance with the requirements of the <br /> waste hauler,waste handling facility,and state/federal governments. In general, purge <br /> water should be analyzed by methods appropriate for the known contaminants, if any, <br /> that have been historically detected in the monitoring wells. Samples will be collected <br /> and analyzed in accordance with the requirements of the waste disposal facility. , <br /> Wastewater characterization samples may be analyzed for TCLP volatile organic <br /> compounds(VOCs),TCLP semi-volatile organic compounds(SVOCs),TCLP RCRA ' <br /> a?m�6 mpa 2007ipeneraeepsl913C19DJnroslgtiend,iwtl rwa`e ro.grrp u,d dreg"cac <br />
