The same information will be recorded on the <br /> F chain of custody form. Soil samples will be placed in a cooler with frozen gel packs or ice. The <br /> sample cooler will be delivered to the analytical laboratory within 24 hours of collection. <br /> Based on our knowledge of the Site from previous investigations conducted at the Lincoln <br /> c Center, groundwater will be not encountered in any of the borings. Thus, no groundwater <br /> .`' samples will be collected. <br /> 3.4 Laboratory Analyses <br /> Soil samples will be analyzed by a state certified analytical laboratory for the gasoline <br /> constituents' benzene, toluene, ethylbenzene and total xylenes (BTEX) by EPA method 8020. <br /> TPH-g will be analyzed by EPA method 8015,modified. Fuel oxygenates (MtBE, TAME, DIPE, <br /> ETBE and TBA) and lead scavengers (EDB and 1,2-DCE) will be analyzed by EPA method <br /> 8260b. <br /> I <br /> 3.5 Field Equipment Decontamination Procedures <br /> The sampler will be decontaminated before and after each use by steam cleaning or washing in a <br /> laboratory grade detergent solution, followed by tap water, or deionized water rinses. Potable <br /> water will be used for decontamination of drilling equipment. <br /> All rinseate water used in the decontamination process and all purge water and soil cores from <br /> the temporary wells will be stored on-site in steel DOT approved drums. Drums will be labeled <br /> as to contents, date container filled, company name, and sealed. The drums will be left on-site <br /> ' . for subsequent disposal pending analytical results. <br /> 4.0 UST CLOSURE REPORT <br /> A UST Closure Report will be prepared and submitted to the SJC-EHD and Sims-Grupe <br /> Management Corp. The report will include site history, figures identifying sample locations, <br /> "f1 drilling logs, laboratory analytical reports, a summary of all work performed, a tabulation of <br /> analytical results and conclusions and recommendations regarding additional work, if necessary. <br /> The report will be prepared under the direct supervision of a licensed professional engineer or a <br /> registered geologist. The report will comply with the requirements of the Tri-Regional Board <br /> Staff Recommendations for Preliminary Investigation and Evaluation of Underground Tank Sites <br /> 1 (August 30, 1991). <br /> k <br /> .i \\I"om\d\Cft nl Prvjccl Filc\3944 Srockwn\workpinn,doc <br /> W <br /> I <br />
