8 November 1995 <br /> AGE-NC Project No 95-0130 <br /> Page 7 of 7 <br /> 44 SOIL, VAPOR EXTRACTION PILOT TEST <br /> For performance of a soil vapor extraction pilot test, the following procedures will be performed <br /> I A portable internal combustion extraction system will be set-up on-site and operated for a <br /> period of 8 to 10 hours to determine the subsurface permeability to vapor, radial influence of <br /> the vapor extraction well, and the initial hydrocarbon recovery rate <br /> 2 Four vapor samples will be collected during the test Samples will be collected at <br /> approximately 2-hour intervals and measure the hydrocarbons concentration in the extracted <br /> vapors The samples will then be transported under chain-of-custody to a state-certified <br /> laboratory for analysis Each vapor sample will be analyzed for TPH-g and BTE&X in <br /> accordance with the appropriate EPA methods <br /> 3 Results of the SVE pilot test will be used to determine feasibility of soil vapor extraction at <br /> the site <br /> 45 REPORT PREPARATION <br /> 3 <br /> Upon completion of the pilot test and laboratory analysis, a Corrective Action Plan (CAP) will be <br /> prepared summarizing results of the feasibility testing The CAP will include recommendations for <br /> remediation of impacted soil at the site and, if necessary, further investigation The report will be <br /> reviewed and signed by a California Registered Geologist <br />
