activities. Mr. Yoshioka and Mr. Gipson had previously informed Mr. Fisk that if contamination were <br /> detected in the stockpile or tank samples, this soil would need to be re-excavated and removed. The <br /> product line/dispenser trenches were not backfilled, and the excavated soil remained piled adjacent to <br /> the trenches. <br /> 6.0 RESULTS <br /> Gasoline and BTEX compounds were detected in JL-P-3, and at the request of Elite IV, Upgradient <br /> therefore prepared a Site Contamination Work Plan to excavate the contaminated soil and transport it <br /> to REMCO in Richmond, California for disposal. The workplan was approved by PHS/EHD on <br /> November 13, and the work was performed November 16-22. A separate report describing that <br /> investigation is in preparation. <br /> No hydrocarbons were detected above reporting limits in any of the other samples (Attachment A). <br /> These results are in accord with the field observations described in section 4.0. Four of the five metal <br /> were detected at concentrations ranging from 4.8 to 31 mg/kg. These concentrations are well within <br /> the normal background ranges for native soil. <br /> 7.0 RECOMMENDATIONS <br /> Upgradient Environmental recommends that the northwestern portion of the property, where the <br /> underground storage tanks were formerly located, be considered for site closure. No evidence of soil <br /> contamination has been detected in this area. <br /> Due to the evidence of soil contamination in the front(eastern)portion of the property, this area cannot <br /> be recommended for closure at this time. However, Mr. Fisk has attempted to remediate this area by <br /> authorizing excavation of a considerable volume of soil. When the laboratory results from the remedial <br /> work have been received, Upgradient will provide recommendations concerning the eastern portion of <br /> the property. <br /> 3 <br />
