transfers, and finally to the storage facility or the analytical laboratory, where the laboratory's internal <br /> procedures will govern until final disposition of the samples. This information will be recorded on the <br /> chain-of-custody form which will remain with the samples at all times. Proper taping, locking, and sealing <br /> procedures shall be used to prevent or detect tampering of the samples. The chain-of-custody form(s) will <br /> be used for a packaged lot of samples (i.e., more than one sample will most likely be recorded on a single <br /> form). If all of the samples in a given lot cannot be recorded on a single chain-of-custody form, an <br /> additional form(s) will be used. <br /> WASTE DISPOSAL PLAN <br /> This section provides guidelines for the handling of any potentially contaminated materials generated during <br /> the field activities associated with this investigation. <br /> All soils brought to the surface will be stored in a 20 cu yd rolloff bin. All soil will remain on-site until <br /> analytical results are obtained from the analytical laboratory. The soils will be disposed of appropriately, <br /> based on the chemical analytical results. <br /> The water collected during steam cleaning operation, as well as the water removed from wells during <br /> development, purging and sampling,will be stored on-site in sealed DOT-approved 55-gallon drums. The <br /> drums will be labeled with the well I.D. number(s), date, and nature of the contents. All drummed liquids <br /> will be sampled and properly disposed of based on the analytical results. <br /> California Uniform Hazardous Waste manifests will be completed by PG&E as required for the <br /> 1 transportation and disposal of any hazardous waste that may be generated during the investigation. <br /> Disposal of all'wastes will be conducted in accordance with federal, state, and local regulations. <br /> j <br /> 1 <br /> 1 <br /> l <br /> cca/03/10/95 09:38 AM(0688brpt.doc/ntw12) 4-9 <br />
