Michael Infurna , Jr. <br /> August 21, 2002 <br /> Page 4 of 5 <br /> (TPH-g, BTEX, fuel oxygenates) will be analyzed using EPA Method 8260. Methods may vary <br /> per laboratory. <br /> INVESTIGATION-DERIVED WASTE (IDW) <br /> Waste material; such as soil from drilling, water from cleanup, and used materials and supplies; <br /> will be generated during field investigation activities. IDW will be collected and stored in steel, <br /> 55-gallon drums at the Site. Each waste stream(soil, water, sludge, and other solid materials) <br /> will be segregated and stored separately. Drums will be labeled with the date and type of <br /> accumulated IDW, and will be stored in a designated area at the Site until the waste material is <br /> sufficiently profiled to facilitate disposal. <br /> SITE CONTROL AND DECONTAMINATION PROCEDURES <br /> Control of the working area during Site investigations will be accomplished using cones and <br /> barricade tape. Persons not directly involved with field investigation activities will not be <br /> allowed within exclusion zones defined by the barriers. <br /> Equipment brought to and used at the Site will be clean prior to introduction to work areas. <br /> Between sample locations and sampling intervals, sampling equipment will be cleaned to prevent <br /> cross-contamination between samples. Decontamination of equipment will be accomplished by <br /> initially washing the equipment with a non-phosphate, laboratory-grade detergent, double rinsing <br /> in potable water, and a final rinse with distilled water. Decontamination of equipment will be <br /> performed in an established exclusion zone at the Site. No materials will be allowed to enter <br /> storm drain inlets. <br /> Materials used at the Site will be new and free of residual petroleum and other organic chemical <br /> products. <br /> SITE RESTORATION <br /> Following completion of field work, work areas will be cleaned and restored to as close to <br /> original condition as feasible. Loose debris will be removed, as well as discoloration, as <br /> reasonable. The surface of sealed borings will be finished in a fashion approximating the <br /> surrounding surface. <br /> 3023-03/104700.4766.230/AUG2 1'02 <br />
