VVZ <br /> 8 INC <br /> 6 0 HYDROCARBON IMPACTED SOIL REMEDIATION PLAN <br /> 6.1 Characterization of Stockpiled Hydrocarbon Impacted Sal <br /> The 3,000 cubic yards of gasoline impacted soil that was excavated from the former <br /> gasoline tank (Tank#1) site at the Hi Hopes property and stockpiled on the remediation <br /> pad was sampled by WZI on September 16, 1996 Samples were collected from soil 4 to <br /> 5 inches below the surface of the remediation pad Brass tubes were driven into the soil, <br /> sealed and stored in ice pending delivery to the analytical laboratory Exhibit 8 depicts the <br /> locations Analytical results of the soil samples used to characterize the remediated soil <br /> are summarized in Table 2 The samples were analyzed using USEPA Test Method <br /> 8015(M) for total petroleum hydrocarbons as gasoline fuel and USEPA Test Method 8020 <br /> for benzene, toluene, ethyl benzene, and xylene Laboratory analytical reports are <br /> presented in Appendix IV of this report Concentrations of gasoline fuel in the soil were <br /> reported to range from below laboratory analytical detection limits to 15 mg/kg with an <br /> average of approximately 3 mg/kg Volatile organic compounds identified by USEPA Test <br /> Method 8020 were reported as a maximum of 2 6 mg/kg with an average of under 1 <br /> mg/kg Since the overall average of volatile organic compounds in hydrocarbon impacted <br /> soil on the remediation pad is below 50 mg/kg the entire volume of soil will be aerated at <br /> one time in accordance with Air District Rule 40 <br /> 62 Gasoline Contaminated Sal Remediation and Final Fate <br /> The following procedures outline the methodology that will be used in remediation of the <br /> approximate 3,000 cubic yards of gasoline impacted soil <br /> i <br /> 08220010 031 33 <br />
