kAll samples will be shipped to a California-certified laboratory using chain-of-custody <br /> procedures for analysis. Upon completion of the grab groundwater sampling, the boring will <br /> be abandoned by backfilling with a cement grout tremied into the boring through the <br /> sampling rods. <br /> Potential soil and groundwater sample analyses are summarized in Table 1.Table 2 <br /> summarizes the required sample containers,preservations,and holding times. <br /> i . 3.2 Equipment Decontamination <br /> At each drilling location,an area will be established for equipment decontamination. All CPT <br /> drill rods,and soil and groundwater sampling equipment will be steam cleaned before use, <br /> and between each soil boring. <br /> j 3.3 Waste Disposal Plan <br /> Two types of waste will be generated during the activities described in this work plan: <br /> E <br /> • Rinse water from decontamination of equipment <br /> • Suits/protective clothing <br /> i (CPT logging/boring does not generate drill cuttings). <br /> All wastes are to be considered Del Monte-generated wastes. During the field investigation, <br /> CH2M HILL personnel will be responsible for placing wastes in labeled storage containers. <br /> Del Monte is responsible for determining the ultimate disposal method,preparing wastes for <br /> shipment,and arranging transportation for the waste. Del Monte will sign all shipping <br /> i manifests. CH2M HILL will provide 55-gallon drums. Del Monte will provide any other <br /> necessary storage containers. <br /> The following waste disposal plan assumes all generated wastes will be stored in 55-gallon <br /> drums in a location to be arranged by Del Monte. All hazardous wastes will be disposed of <br /> within 90 days of their collection. <br /> 3.3.1 Decontamination Solutions, and Rinse Waters <br /> Wastewater will be generated from equipment decontamination. If prior approval is received <br /> from the local POTW, these waters may be disposed of directly to the local sanitary sewer <br /> system. Alternatively, these waters will be stored onsite in a polyethylene storage tank(s) or in <br /> 55-gallon drums. The tank(s)will be stored in a fenced,posted,and secured area. The tank(s) <br /> or drums will be labeled with information indicating the source of the fluids. All wastewater <br /> will ultimately be managed according to federal,state,and local regulations. <br /> 3.3.2 Suits/Protective Clothing <br /> Protective suits and clothing will be generated each day. These wastes will be placed in plastic <br /> storage bags and deposited in a 55-gallon drum. The drums containing protective clothing <br /> will be removed,transported,and disposed of with the drums containing the drill <br /> cuttings/care material. <br /> SFOICABERNET/GROUPS/EBG/DELMONTEIPLANT_33IWORKPLAN_CPT.DOC 6 <br />
