Phase II Work Plan 304 E. Weber Avenue Page 3 Each soil sample collected for laboratory analyses will be cut from the liners. The liners will be sealed at the ends with Teflon® sheeting, capped, and labeled. The samples will be placed in a cooler with ice and delivered under chain-of-custody (COC) procedures to a California certified laboratory for analyses. Groundwater samples will be collected from each borehole using a discrete depth sampling tool. At least 12 groundwater samples will be collected. The sampling tool consists of a stainless steel well screen sealed inside stainless steel casing. An expendable point will be attached to the base of the tool and the tool advanced to the desired sample depth. The casing will be pulled back to expose the screen and to allow groundwater to flow into the sample chamber. Groundwater in the chamber will be retrieved using a stainless steel bailer. Following sample collection, the sampling equipment will be removed from the boring and cleaned using laboratory-grade non-phosphate detergent and deionized water. The equipment will be double rinsed with de-ionized water. Groundwater samples will be retained in 40 milliliter (m1) volatile organic analyses (VOA) vials fitted with a Teflon-lined septum and clean, one-liter glass bottles provided by the analytical laboratory. 3.4 LABORATORY ANALYSES The soil and groundwater samples will be delivered under COC procedures to a state certified laboratory for analyses. The soil samples collected from the borings will be analyzed for Total Petroleum Hydrocarbons quantified as gasoline (TPH-G) and Total Extractable Petroleum Hydrocarbons (TEPH) by EPA Method 8015B, for Volatile Organic Compounds (VOCs) by EPA Method 8260B, SVOCs by Method 8270C, and CAM 17 Metals by Method 6010B and 7417A. The groundwater sample collected from each borehole will be analyzed for TPH-G, VOCs, SVOCs, and CAM 17 Metals. REPORTING Condor will prepare the Limited Phase II ESA Report detailing the findings of the investigation to be submitted to Mr. Karam and to the SJCEHD. The report will include a discussion of the field and laboratory procedures used to conduct the investigation, a discussion and presentation of the analytical results, and conclusions regarding the potential for contamination at the Site. PROJECT SCHEDULE AND COST Upon approval of this Work Plan by the Mr. Karam and SJCEHD, and acquisition of the boring permits, the field portion of the investigation is scheduled to begin April 2, 2007. A verbal summary of the investigation results can be submitted to Mr. Karam by April 13, 2007, followed by a written report by April 27, 2007. If you need additional information or have any questions, please call Robert Job at (209) 532 0361. Condor is proposing to conduct all tasks associated with the above-described Phase 11 ESA on a time- and-materials basis for a total estimated cost of approximately $98,850. Attached is a detailed estimate of the associated costs by task. CONDOR
