6. The results for soluble lead from the excavation bottom and two background samples <br /> indicate the presence of elevated levels of soluble lead in onsite shallow soils. The <br /> occurence of lead is unrelated to the presence of the wood debris, and is present in the <br /> historic fill at the site. <br /> 3.0 SITE CLEANUP ACTIVITIES <br /> 1. A February 16, 1993 meeting between CDFG, SJCPHS, Santa Fe, and Environmental <br /> Solutions, Inc. resulted in Santa Fe's agreement to remove remaining wood chips from the <br /> surficial soils at the Jersey Island staging area to the satisfaction of CDFG. It was also <br /> determined that the presence of elevated levels of soluble lead in the soils at the site was a <br /> pre-existing condition. <br /> 2. On February 17, 1993, personnel from Claude C. Wood Company and Santa Fe were <br /> mobilized on site to remove the wood chips from the soil. The affected area was <br /> mechanically raked using a tractor to uncover buried wood chips and then manually <br /> cleaned of wood chips using rakes,buckets and wheel barrows. Wood chips were collected <br /> and stored in a 20-cubic yard roll-off box. The wood chips were profiled as non-hazardous <br /> waste at Chemical Waste Management's (CWM) Kettleman Hills facility. The wood chips <br /> were disposed at CWM's Kettleman Hills Facility due to the initially high lead levels found <br /> in the soils and the potential for lead contaminated soils adhering to the wood chips. <br /> Although the wood chips were physically separated from the soils,BFI's Vasco Road <br /> Landfill was hesitant to take the remaining wood chips due to the low level of lead <br /> permitted at their Landfill. <br /> 3. Following initial cleanup efforts, a site inspection was conducted on March 23, 1993 by <br /> Mr. Art Ramirez,Warden with CDFG, and personnel from Environmental Solutions, Inc. <br /> During the site inspection, Mr. Ramirez indicated that the area was not cleaned to his <br /> satisfaction and that further effort would be required. <br /> 4. A meeting was conducted between Santa Fe, Claude C. Wood Company, and <br /> Environmental Solutions, Inc., on March 25, 1993 to re-evaluate the technique used to <br /> remove the wood chips. It was agreed that the current method of wood removal would be <br /> sufficient. Starting on March 29, 1993, an intense effort was made to remove the wood <br /> chips. Two additional 20-cubic yard roll-off boxes were delivered to the site. In addition <br /> to the manual raking of the soils, a mechanical screen was used on site to assist in the <br /> 5 <br /> ENVIRONMENTAL SOLUTIONS <br />
