Ll KLEINFELDER <br /> File No. 20-3978-O1.W32 <br /> May 23, 1997 <br /> also prepare a health and safety plan for use in the field. The health and safety plan will be <br /> included as part of the workplan. <br /> Laboratory Analysis <br /> A total of two composite samples and two confirmation samples will collected and transported <br /> under chain-of-custody control. The soil samples will be transported to the Kleinfelder office in <br /> Stockton and then transported by courier in a sealed container to Sequoia Analytical of <br /> Sacramento, California (Sequoia) for chemical analyses. Sequoia is certified by the California <br /> Department of Toxic Substances to perform the requested analyses. The four soil samples will <br /> be analyzed for- Total Threshold Limit Concentration (TTLC) and Soluble Threshold Limit <br /> Concentration (STLC) Lead. It is anticipated that samples will be analyzed on a normal <br /> laboratory turnaround schedule, which usually requires up to 10 working days for receipt of <br /> analytical data. <br /> Transportation and Disposal of Excavated Soil <br /> RAH Environmental will transport the excavated soil in DOT approved 55-gallon drums to an <br /> approved sanitary landfill following receipt of analytical results for said soil. For purposes of <br /> this proposal and the attached cost estimate, we assume the soil will be classified as a "Non- <br /> RCRA Hazardous Waste". <br /> Report Preparation <br /> Upon completion of the soil sampling and our receipt and review of the analytical results, a <br /> report will be prepared for client review. The report will include: <br /> • A description of field activities, observations, and protocols; <br /> • Bills of Laden and Hazardous Waste Manifests; <br /> • Tabularized results of soil sample analysis with copies of certified analytical <br /> laboratory results with chain-of-custody documentation; <br /> • Conclusions and recommendations. <br /> All information gathered during the study by Kleinfelder is considered confidential and will be <br /> released only upon written authorization from the client or as required by law. California law <br /> requires a person to inform the state if a situation is encountered that can be considered an <br /> immediate endangerment to the public's health or welfare and/or to the environment. <br /> 01997,Klein elder,Inc. <br /> 20-3978-0l.W321/20I7P0l8 Page 5 of 8 .( <br />
