Project No. 013-10101 <br /> Page No. 5 <br /> • During drilling of the proposed borings, the drill cuttings (soil) will be subjectively analyzed for <br /> odor and discoloration. Additionally, the soil will be field-screened with a portable PID <br /> calibrated to 100-ppm isobutylene. No drill cuttings will be produced during this assessment. <br /> • Soil samples will be obtained by means of a split-spoon Modified California Sampler containing <br /> three 6-inch-long by 1.5-inch-diameter stainless steel liners or 18-inch-long by 1.125-inch <br /> diameter acetate liners. Once collected, the ends of each sample liner will be covered with <br /> Teflon& film, capped with plastic end caps, labeled, placed into a plastic bag, sealed, and then <br /> placed into a thermal chest cooled with ice for delivery to a state-certified analytical laboratory. <br /> • Soil sampling will be conducted in accordance with Appendix C of the March 1998 version of the <br /> Leaking Underground Fuel Tank (LUFT) Field Manual published by the State of California <br /> Water Resources Control Board. <br /> • Equipment used for the advancing of soil borings and collection of soil samples will be <br /> decontaminated (steam-cleaned, TSP, lab grade detergents, etc.) before arriving on site, between <br /> each boring and/or sampling interval, and before leaving the site each day, or as deemed <br /> necessary by the Krazan field engineer to reduce the chances of cross-contamination. The <br /> decontamination fluids (rinsate) will be temporarily contained in DOT-approved steel 55-gallon <br /> sealable drums. The rinsate will be stored on the subject site,pending the results of the chemical <br /> analyses,and will be disposed by LNAS within 90 days following material generation as deemed <br /> warranted by sample analytical results. Krazan is not the generator of the rinstate and is not <br /> responsible for its proper disposal. Krazan can assist in the proper disposal of impacted rinsate, <br /> if any. <br /> • Field work would be conducted by individuals meeting Occupational Safety and Health <br /> Administration requirements for hazardous waste work including 40-hour health and safety <br /> training and medical monitoring. The work would be completed under the standards set forth by <br /> the industry and deemed acceptable by various regulatory agencies. Hard hats, protective <br /> eyewear, steel-toe boots, protective clothing, and respiratory devices will be worn by Krazan <br /> personnel when deemed appropriate by the field engineer present. <br /> • Selected soil will be analyzed for the constituents of concern and analytical methods noted below. <br /> KRAZAN&ASSOCIATES,INC. <br /> Conducting Assessments Nationwide <br /> 1310101 United Rentals Workplan <br />
