1 <br /> �►�rum� <br /> Site SafetyPlan t <br /> 1� Field work performed by Applied GeoSystems, Inc /RESNA Industries (RESNA) at the site <br /> will be conducted in accordance with RESNA's Site Safety Plan This plan will describe the <br /> safety requirements for drilling soil borings at the site The Site Safety Plan will be <br /> applicable to personnel and subcontractors of RESNA RESNA personnel and <br /> subcontractors scheduled to perform work at the site will be briefed on the contents of the <br /> Site Safety Plan before work begins A copy of the Site Safety Plan will be available for <br /> reference by appropriate parties during the work The onsite Staff Geologist of RESNA will <br /> act as the Site Safety Officer <br /> Soil Sampling <br /> During sampling, the geologist will use a field photoionization detector (PID) to characterize <br /> the relative levels of hydrocarbons Field instruments such as the PID are useful for <br /> indicating relative levels of hydrocarbon vapors, but do not detect the concentration of <br /> hydrocarbons present with the same precision as laboratory analyses One of the samples <br /> in brass sleeves not selected for laboratory analysis at each sampling interval will be tested <br /> in the field using an PID This testing will be performed by placing the intake probe of the <br /> PID against the soil after opening the brass container <br /> Soil Sampling in Tank Cavity <br /> The soil will be brought to the ground surface in an excavator bucket, and the outer soil will <br /> be scraped away A clean, 6-inch-long, 2-inch-diameter, clean brass tube will be driven into <br /> the soil using a percussion sampler The brass tube will be removed and the ends covered <br /> with aluminum foil and plastic end caps and taped The tube will be labeled and <br /> immediately placed on ice for transport to the laboratory Chain of Custody Records will <br /> be maintained throughout delivery to the laboratory <br /> Samoling Stockpiled Soil <br /> Soil samples will also be collected from the stockpiled soil to evaluate treatment or disposal <br /> options Four soil samples will be collected for approximately every 50 cubic yards of <br /> stockpiled soil Each group of four samples will be composited into one sample by the <br /> laboratory Soil samples will be collected in clean brass tubes from approximately 6 inches <br /> below the surface of the stockpiles <br /> 30003.4W <br />
