A <br /> Site Safety Plan <br /> 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 Samoling <br /> During sampling,the geologist will use afield 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 /> r 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 /> Y PID against the soil after opening the brass container. R <br /> 3 <br /> i <br /> Soil Sampling in,Tank Cavi <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 /> j 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 /> u be maintained throughout delivery to the laboratory. <br /> Sampling Stockpiled 5oi1 <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 SO 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 /> '.rs <br /> 30003-4W <br />
