5 April 1993 <br /> (GeoAudit 652-S) <br /> Page 3 of 3 <br /> PHS/EHD will indicate the number and location of the soil <br /> samples after the excavation is completed. We anticipate <br /> collecting approximately six soil samples from the floor of <br /> the excavation. <br /> 8) Cap samples, seal with tape and store on ice pending analysis. <br /> 9) Label and log soil samples on a chain-of-custody form. Samples <br /> will be transmitted to a state certified laboratory. <br /> 10) Analyze soil samples for total petroleum hydrocarbons (TPH as <br /> gasoline and diesel, EPA 8015m) and volatile aromatics (BTE&X, <br /> EPA 8020) . <br /> 11) Prepare a written report summarizing the results of the above <br /> investigation in a format to be submitted to the PHS/EHD and <br /> the Central Valley Regional Water Quality Control Board <br /> (CVRWQCB) . <br /> The opportunity to prepare this work plan is greatly appreciated. <br /> Please contact our office if you have any questions or comments. <br /> Sincerely, <br /> GEOLOGICAL AUDIT SERVICES, INC. <br /> /� -.1-Z %� <br /> Bob Marty Kevin McKibben <br /> Pro)ect Geologist Staff Geologist <br />
