1 <br /> samples will be analyzed for petroleum hydrocarbon constituents as specified in Section 3.7 <br /> below. Ground water encountered in the excavation will not be sampled. <br /> ' 3.5 Remediation of Excavated Soil <br /> Uncontaminated soil will be stored separately and used as fill in the completed excavation. <br /> ' Contaminated soil will be transported to a temporary containment site located on the property. <br /> The asphalt pad which will receive the contaminated soils will be covered with plastic sheeting <br /> to prevent leaching of contaminants from the contaminated soil. Upon completion of the <br /> excavation and transport of all of the contaminated soil to the temporary containment area the <br /> stockpile will be covered with plastic sheeting. <br /> ' After completion of the excavation, composite samples will be collected from the contaminated <br /> soil stockpile. One four-point composite sample will be collected for every 200 cubic yards of <br /> ' soil in the stockpile. The analysis of the soil will be performed to characterize the soil for mass <br /> balance calculations and remediation permitting purposes. <br /> ' AGS proposes to remediate the soil using an air stripping method. Soils will be spread on an <br /> asphalt or plastic lined pad in a thin layer to allow contaminants to volatilize. Mechanical <br /> turning or tilling may be employed to accelerate the aeration process. Soils will be added to the <br /> aeration pad in order to maximize remediation rates while remaining within permitted limits. <br /> Field based monitoring techniques will be utilized to determine contaminant levels during the <br /> remediation process. Upon attainment of field based target levels, confirmation samples will be <br /> collected for laboratory analyses. One two-point composite sample will be collected for every <br /> 100 cubic yards of remediated soil. Soils that have attained non detectable gasoline and BTEX <br /> levels will be removed from the aeration pad and stockpiled for on-site disposal. It is anticipated <br /> that remediated soils will be reclaimed by adding it to the adjacent arable land also owned by <br /> ' Western Refrigerating and Cold Storage. <br /> 3.6 Monitoring of Working Headspace <br /> To minimize any potential safety and health hazards from volatile compounds in the working <br /> space a PID will be employed to frequently monitor the working space. In addition, a hand <br /> pump with contaminant specific detector tubes will be utilized to monitor for the presence of <br /> benzene. <br /> 3.7 Laboratory Analysis of Soil Samples <br /> I ' All soil samples collected for analysis will be stored in a cooler chilled to 4' Celsius and shipped <br /> under strict chain of custody protocol to the analytical laboratory. The samples will be analyzed <br /> in Modesto, California by GeoAnalytical Laboratories, a California State certified analytical <br /> ' laboratory for the following constituents: <br /> American Geological Services, Inc. <br /> CA95DE-029 <br /> 7 <br />
