1 <br /> It is anticipated that this treatment process will require between four to six weeks for the complete <br /> degradation of the petroleum hydrocarbon residues At the end of six weeks, confirmation sod <br /> sampling will be conducted <br /> 24 Confirmation Soil Sampling <br /> ' In order to verify the success of the remedial process confirmation soil sampling will be conducted <br /> The treatment bed will be sectioned into a sampling grid with approximately 50 cu yds of soil in <br /> ' each identified grid segment From each grid segment, a composite soil sample will be collected <br /> from three separate locations within the segment The samples will be collected from a minimal <br /> depth of eight inches beneath the bed's surface The composite samples will be collected in 2 inch <br /> diameter stainless steel tubes The tube will be filled approximately one third full from each of the <br /> ' three grid segment sample collection locations Precautions will be taken to preclude compound <br /> volatilization during the sample compositing This will be done by covering the ends with aluminum <br /> foil in-between collection locations <br /> Once collected, the samples will be sealed with aluminum foil and plastic end caps The end caps <br /> will be sealed with elastic tape The samples will then be labeled and placed into zip-lock plastic <br /> 1 bags and kept in a refrigerated cooler for shipment to the analytical laboratory A sample chain of <br /> custody form will accompany the sample shipment The samples will be analyzed for TPH-G using <br /> DOHS Method 8015 and for BTX&E using EPA Method 8410 Additionally, four duplicate samples <br /> will be collected for confirmation sample analysis These duplicate samples will be analyzed by <br /> ' TreaTek's analytical laboratory <br /> Between each sample collection location and between sampling each grid section, the sample <br /> collection equipment shall be thoroughly decontaminated by washing with a laboratory reagent <br /> soap/water mixture and rinsing with potable water A final deionized water rinse will complete the <br /> decontamination procedure <br /> ' 30 REMEDIAL REPORTING <br /> As was stated previously, TreaTek shall maintain a dedicated field log book for the project All site <br /> ' remedial activities shall be documented within this log book <br /> Additionally, an activity log sheet shall be kept onsite An example of a typical remedial activity log <br /> ' sheet is included as Appendix B This log sheet will provide documentation for tilling, inoculation <br /> and nutrient/moisture supplementary activities This sheet will also provide documentation as to the <br /> periods in which the soil treatment bed is uncovered <br /> Once the remediation has been completed and the results of the confirmation soil sampling have <br /> been received, a final remedial report will be prepared The report will provide detailed discussions <br /> of the remedial activities and the confirmation sample analyses Included in the report will be <br /> ' recommendations for the treated soil disposition <br /> 40 PROJECT ORGANIZATION AND MANAGEMENT <br /> ' Day-to-day management of the project will be performed by Mr Erik A Friedrich In this capacity, <br /> Mr Friedrich will be responsible for the overall technical quality of the project, adherence to health <br /> ' and safety protocols as well as budget, schedule and deliverables Mr Friedrich will be aided in <br /> this capacity directly by Mr Thomas Prevost and Mr Jason Garth, Project Engineers/Technicians <br /> 7 <br /> 1 <br />
