WZr INC <br /> The hydrocarbon impacted soil was spread in lifts not exceeding 18 inches in height on <br /> the Hi Hopes property approximately 200 feet south of the excavation The samples were I <br /> submitted to a State of California certified analytical laboratory and were analyzed for total <br /> petroleum hydrocarbon as gasoline and benzene, toluene, ethyl benzene, and xylene to <br /> determine initial volatile organic compound concentrations using USEPA Test Methods <br /> 8015 (modified) and 8020, respectively The maximum concentration for the 3,000 cubic <br /> yards of hydrocarbon impacted soil was determined to be as follows total petroleum <br /> hydrocarbon as gasoline (<15 mg/kg), benzene (<1 mg/kg), toluene (<1 mg/kg), ethyl <br /> benzene (<1 mglkg), and xylene (<3 mg/kg) These data were used to establish the initial <br /> volume of hydrocarbon impacted soil that can be remediated on a daily basis Because <br /> the concentrations were below 50 mg/kg of volatile organic compounds, the entire volume <br /> of 3,000 cubic yards of hydrocarbon impacted soil can be aerated on a daily basis in <br /> accordance with Rule 40 of the San Joaquin Valley Unified Air Pollution Control District <br /> (Air District) <br /> The Air District has been notified of the intention of Hi Hopes to aerate the hydrocarbon <br /> impacted soil Once target soil remediation levels have been obtained as documented by <br /> soil sample analytical data, an application to discontinue remediation operations will be <br /> submitted to both the Air District and PHSEHD The remediated soil will be left onsite and <br /> utilized as roadbase material <br /> I <br /> 08228010 011 6 <br />
