LFR Inc. <br /> Response records of on-site personnel, and assisted with administering a medical <br /> surveillance program. <br /> Collected health and safety monitoring air samples were analyzed for heavy metals, <br /> sulfur compounds, VOCs, and polynuclear aromatic hydrocarbons (PAHs). Sampling <br /> methodology, air monitoring results and worker exposures are summarized in the Air <br /> Monitoring Report presented in Appendix D of this report. <br /> Generally, SBES concluded that no applicable thresholds developed to protect worker <br /> health and safety were exceeded for VOCs, metals, PAHs, or total dust during the <br /> health and safety air monitoring conducted by SBES. SBES also concluded that the <br /> permissible exposure limit for total nuisance particulates of 10,000 micrograms per <br /> cubic meter (set by Cal-OSHA) was never exceeded during the site operations and that <br /> site operations therefore did not present a significant health risk to personnel at the <br /> Site. <br /> NES Summary. NES, working under the direct supervision of the CIWMB, conducted <br /> additional health and safety air monitoring of individuals, background (ambient) <br /> conditions, and area stations on July 13 and August 2, 2005. <br /> Collected health and safety monitoring air samples were analyzed for TPH, VOCs, <br /> PAHs, heavy metals, sulfurous compounds, and total dust. Sampling methodology, air <br /> monitoring results and worker exposures were summarized in the Industrial Hygiene <br /> Air Sampling Results report presented in Appendix D of this report. <br /> Generally, NES concluded that, based on the air sampling analytical results, the <br /> analyzed particulates were well below any published worker exposure guidelines or <br /> regulatory limits. However, due to the highly odorous compounds released during <br /> some of the excavation activities and due to the low concentrations (0.012 to 0.021 <br /> parts per million) of benzene that were detected in the air samples collected from the <br /> excavation area, NES concluded that the PPE (level "C") and procedures used by the <br /> workers on site were appropriate for the compounds detected during the two sampling <br /> events conducted by NES. <br /> 5.9 Waste Transportation and Disposal <br /> Waste invoices, copies of manifests, and landfill activity reports that include waste <br /> disposal quantities for each truck load were received to track the quantity of wastes <br /> transported each day. A total of 387,435 tons of waste material comprising over 16,000 <br /> truck loads were removed from the Site for disposal at licensed landfills in California. <br /> Digital copies of the waste transport and disposal manifests were compiled on compact <br /> discs and are presented in Appendix E. Table 4 summarizes the tonnages, number of <br /> truck trips, waste destination, and transportation/disposal costs for the wastes removed <br /> from the Site. <br /> Page 32 rpt-RA_summ-Nov06-fina1-09025:FNC <br />
