AZURE ENVIRONMENTAL <br /> 2,0 SCOPE OF WORK <br /> The Scope of Work for treatment cell closure has been organized into specific tasks as follows: <br /> Task 1: Confirmation Soil Sampling <br /> Task 2: Preparation of Soil Treatment Cell Closure Report <br /> A detailed description of each task follows. <br /> Task 1: Confirmation Soil Sampling <br /> To obtain representative data of petroleum hydrocarbon concentrations remaining in the treatment <br /> cell soil, eight (8) soil samples will be collected on a and pattern superimposed on the treatment <br /> cell (Figure 1). The soil samples will be collected at a depth of 2 to 3 feet below grade. <br /> Additionally, two (2) soil samples will be collected from the soil berm that bounds the treatment <br /> cell. The samples will be collected at a depth of 2 feet below the top of the berm. <br /> The soil samples will be submitted to a California state-certified laboratory and analyzed for total <br /> petroleum hydrocarbon (TPH) analysis characterized as gasoline and diesel (EPA Method <br /> 801515030) and BTEX (EPA Method 8020). i4 f t%t <br /> The soil samples will be collected using either hand auger equipment or a shovel. The sampling <br /> equipment will be decontaminated prior to reuse at each sampling location. The soil sample <br /> selected for laboratory analysis will be collected in glass jars, labeled and then placed in an ice- <br /> chilled cooler for transport to the laboratory. All work will be performed under the direction of a <br /> California Registered Geologist. <br /> Task 2: Preparation of Soil Treatment Cell Closure Report <br /> Soil analysis data collected from the confirmation soil san .)ling activities will be evaluated, <br /> summarized, and a report prepared by a California Registered Geologist. The report will include <br /> the following: <br /> • Detailed descriptions of the methodologies used to collect and analyze the data; <br /> • Appropriately scaled base maps showing all sample locations; <br /> • Presentation and interpretation of soil analytical results; and <br /> • A rationale for recommending additional soil remediation and/or closure of the soil treatment <br /> cell, in accordance with San Joaquin County Public Health Services (SJCPHS) requirements. <br /> 2 <br /> *© <br />
