additional contamination is identified. These samples will be tested for BTEX and <br /> TPH-full range using EPA methods 8020 and 8015. (unless otherwise directed by the <br /> regulatory agencies). All samples will be collected and analyzed by a certified <br /> environmental laboratory and are subject to comprehensive QA/QC protocol. The <br /> overall objective of this protocol is to meet federal and state standards for precision <br /> and accuracy. <br /> • Once all contaminated soil is identified and placed in the biocell, enzyme solution <br /> will be applied in the required concentrations and the biocell covered. Soil moisture <br /> will be maintained at 20%by volume The application will be repeated at 7-day <br /> intervals throughout the bioremediation process. <br /> Completion Criteria ? <br /> The treatment of the hydrocarbon coKess <br /> tion soils will be completed when concentrations <br /> of diesel are less than 50 ppm and BTEXn 10 ppm. This level should be reached within 30 <br /> days from the start of treatment. In most cases, contaminants treated with the FyreZymel system <br /> reach non-detect within 30 to 45 days from treatment. Cleaned soil will be used to backfill the <br /> excavation site. <br /> Sampling <br /> Samples will be taken at the rate of 2 per 100 cubic yards of soil for a total of 25 samples <br /> (unless additional samples are required by regulatory agencies). Testing of each of the samples will <br /> tom, consist of EPA method 8015 and for every second sample 8020 (unless otherwise directed by the <br /> regulatory agencies). All samples collected are subject to comprehensive QA/QC protocol. The <br /> overall objective of this protocol is to meet federal and state standards for precision and accuracy. <br /> Sampling and analysis will be conducted by Brown and Caldwell. <br /> Final Report <br /> A final report will be prepared within 30 days of project completion which will summarize the <br /> procedures used during the demonstration,results of laboratory analysis, and discuss any problems <br /> encountered. <br /> Project Management <br /> Project management organization plays a critical role in determining the success of a remedial <br /> action project. The scope of this project requires careful operations planning as well as the selection <br /> of a project team capable of carrying out the various operational tasks in a safe, orderly manner. <br /> This approach is composed of four key elements including QA/QC, health and safety, environmental <br /> compliance and contract administration. The team that has been assembled for this project has been <br /> selected based upon the required job function qualifications and previous remedial action experi- <br /> ence. Further, G. R. Kause Construction has selected key individuals who have significant relevant <br /> ..r experience. These individuals will be dedicated to the project and will provide an environmentally <br /> sound and economical remediation program. The organizational structure of the G. R.
