�# kn!4KLEINFELDER'l <br /> .61 <br /> sample from each area will be field—screened with ,a flame ionization <br /> detector (FID) If high FID readings are recorded, ','aeration will continue <br /> and the soil will be reserved at a :later date. <br /> Once relatively low FID readings are recorded from the aerating soil, a <br /> confirmation sample will be collected from the survey point with the <br /> highest FID reading.. The sample will be submitted under chain—orf—custody <br /> E to a certified analytical laboratory and analyzed for total' :petroleum <br /> r <br /> hydrocarbons by GC—FIS]. If the analytical results of the confirmation <br /> rl sample are greater than or equal. to 300 mg/kg, aeration of the soil will <br /> continue until the TPH concentration of less than 300 mg/kg is .achieved. <br /> If the results are less than 300 mg/kg, then the soil will b'e used as <br /> daily or intermediate cover at the landfill. White waiting for the <br /> confirmation sample result, the aerating soil. will be piled until the <br /> reduced TPH concentration has been confirmed. Once the aerated' soil has <br /> been piled, the next section of unaerated soil can begin the same aeration <br /> process. The contaminated soil will be aerated at a, rate of approximately <br /> 60 cubic yards per section until the 400 cubic yards of stockpiled soil <br /> F i <br /> s <br /> has undergone the aeration process. Soil that!i has a confirmed TPH <br /> concentration below 300 mg/kg will be used as daily or intermediate cover. <br /> cl <br /> ;i <br /> sl <br /> it <br /> 'i <br /> 59-87-679 5 <br /> i <br />
