This <br /> method of temporary storage is appropriate for the soil materials that will be <br /> generated during drilling because previous investigations have shown the presence <br /> of soil contamination only in the immediate vicinity of the former tanks locations. <br /> However,if field observations(visual,olfactory or photoionization detector readings) <br /> indicate that the soil cuttings may contain petroleum hydrocarbons, the cuttings will <br /> be placed into clean 55-gallon open-head drums. <br /> Contents of the drums will be labeled as "soil pending laboratory analysis". The <br /> labels will include information indicating when, where, and how the soil materials <br /> were generated, as well as who to contact for additional information. The drums will <br /> be temporarily stored near the storage building on site. <br /> Ultimate disposal of the soil cuttings will be determined after the results of <br /> laboratory analyses performed on soil samples are reviewed. If the results indicate <br /> that there is no petroleum contamination present in the soil samples analyzed, the <br /> soil cuttings will be left on site for Ford New Holland to spread over the unpaved <br /> equipment storage yard. If the results indicate the presence of petroleum <br /> contamination in the soil samples analyzed,the soil cuttings will be transported under <br /> a Uniform Hazardous Waste manifest by a licensed hazardous waste hauler to an <br /> appropriate disposal facility. Depending upon the concentrations of petroleum <br /> hydrocarbons detected, the soil cuttings would probably be disposed of either at a <br /> Class I or Class II landfill facility. <br /> Soil Sample Collection Procedure <br /> The well will be drilled using a rig equipped with an 8-inch O.D. hollow-stem auger. <br /> Undisturbed soil samples will be collected using a modified California split-spoon <br /> sampler. The sampler will be lined with clean six-inch stainless steel or brass sleeves. <br /> Samples will be collected at approximately five-foot depth intervals, starting at five <br /> feet below ground surface, to the total depth drilled (approximately 18 to 20 feet <br /> below ground surface). <br /> Selected samples will be retained in the sampling sleeves for laboratory analysis. <br /> Adjacent samples will be used for field headspace measurements. Samples selected <br /> for laboratory analysis will be labeled and sealed with aluminum foil or Teflon sheets <br /> and plastic end caps. The sealed samples will be enclosed in ZiplocT" bags and <br /> wrapped with electrical tape to ensure stability of the end cap seals. These selected <br /> samples will be placed in a thermally-insulated chest containing ice and delivered <br /> j w caren <br /> no ar <br /> t <br />
