2.2 Location and Depth <br /> Drilling will take place at a time agreed upon by TVG and CFM but not later <br /> than 30 days after approval of San Joaquin County, near the previous position <br /> of the gasoline tank on the site. The soil boring will be drilled to the <br /> appropriate depth using a hand auger. Since new, clean backfill was used to <br /> fill in the excavation, we propose to sample just below the new backfill. We <br /> �. estimate the depth to be at 17 feet. If field monitoring indicates the presence <br /> of hydrocarbons at 17 feet, then an additional sample will be taken at 20 feet. <br /> See Figure'2 for location of soil borings. ik <br /> 2.3 Soil Sampling <br /> The samples will be taken at the appropriate depths using a brass tube that <br /> will be sealed and logged under chain of custod': <br /> li <br /> 2.4 Monitoring Wells I <br /> At this time, no provision for monitoring wells is being planned. The <br /> previous monitoring well located at the site indicated that no groundwater <br /> contamination had occurred. Since the time of the original investigation, the <br /> site has been sealed with an impervious layer,of asphalt that should have <br /> prevented leaching of any potential contaminants. <br /> 2.5 Boring Logs <br /> Detailed logs will be made of each boring. The information gathered will <br /> include: sample depths, horizons of detectable Icontamination, if any, (using <br /> field monitoring techniques), soil classification laccording to the Unified Soils <br /> , <br /> Classification System. �'i <br /> 2.6 Disposition of Soil Boring Cutting <br /> i <br /> Soil cuttings will be stock piled until the results of the analysis are obtained. <br /> Disposition will be made then. <br /> t, <br /> Work Plan Page 2 <br /> Custom Food Machinery <br /> :f <br /> July 1, 1992 ;, <br />
