2 <br /> appropriate method for disposition of the cuttings based on the analytical results <br /> and will be responsible for disposal of the drill cuttings <br /> ' <br /> Soil samples for the y chemical analysis will be collected in brass, stainless steel or clear <br /> acetateliners, sealed with Teflon® tape and plastic end caps, labeled, placed on <br /> ice, and delivered to a state-certified analytical laboratory, along with the <br /> appropriate chain-of-custody documentation Soil samples selected for chemical <br /> analysis will be determined from a head-space analysis using a hand-held photo- <br /> ionization detector (PID) The soil will be placed in a glass tar, sealed, and placed <br /> to a warm atmosphere or contained in the acetate sleeve After approximately 15 <br /> minutes, which is generally sufficient for volatiles to escape from the soil, the PID <br /> probe will be inserted into the container The total volatile hydrocarbons present <br /> are detected by the PID and reported in parts per million The PID will be calibrated <br /> to any isobutylene standard <br /> Generally two to three soil samples from each soil boring will be submitted for <br /> chemical analysis Soil samples selected for analysis typically represent the <br /> ' highest PID reading recorded for each soil boring and the sample dust above first- <br /> encountered groundwater <br /> Site Specific Soil Boring Directions <br /> Generally two soil samples from each soil boring will be submitted for chemical <br /> analysis <br /> Subsurface soil samples will be collected from soil borings and the single <br /> monitoring well boring in an effort to define the lateral and vertical boundaries of the <br /> supposed contaminated soil mass The actual sampling locations will be <br /> dependent on access, surface condition, and potential encountered buried objects <br /> Please reference Figure 3, Site Plan Three DPT borings will be placed laterally <br /> dust beyond the suspected contamination zone If contamination is encountered in <br /> a boring the distance from the presumed center of the contaminated soil (previous <br /> UST location) will be increased and an additional DPT boring will be placed This <br /> procedure may be repeated until clean soil is encountered <br /> Soil samples will be collected approximately every 4 to 5 feet for field screening, <br /> lithologic logging and potential chemical analysis The sample is collected by <br /> pushing a hollow probe head into the soil The probe tube contains a clear acetate <br /> tube After extraction, the tube is examined, cut, and capped The sample is <br /> allowed to warm and the head space is evaluated for volatile hydrocarbons A <br /> ' short section, 4- to 6-inches long, with contained sample is cut from the tube The <br /> B -2 <br />
