On December 4, 2003, approximately 750 <br /> barrels(31,500 gals.) of crude oil were released on property owned by Charles Spatafore at 23577 <br /> Mountain House Parkway, Tracy, California (the Site). The release occurred because an <br /> employee of KAgehiro Ranch, Inc-, (a contractor to Mr. Spatafore) Punctured CPL'S KLM crude <br /> oil pipeline while plowing the overlying fields. CPL'S emergency response activities recovered <br /> approximately 400 barrels of oil,and 350 barrels(14,700 gals.) are estimated to remain in the site <br /> subsurface. Kleinfelder has prepared the Workplan at the request. of Mr. Kagehiro's insurer, <br /> Allied Insurance, and Pegasus MH Ventures I,LLC. <br /> To minimize project lifecycle costs and to accurately define the aside oil impact, Cambria offers <br /> the following comments to the Workplan: <br /> L The workplan proposes sampling following a grid pattern; however, no grid dimensions <br /> were specified. The Workplan figure did not include sample grids or sample locations. <br /> Cambria estimates that 50 ft x 50 It grids sampled on center, would provide sufficient <br /> data to reasonably bracket clean-up costs. <br /> 2. The objectives of the proposed scope of work are to: 1) delineate the vertical extent of <br /> r'"itirra crude oil, and 2) pre-characterize soil for offsiw disposal. In addition, the workplan <br /> rmaromeeM't a methodology for collecting analytical data to support field observations of <br /> Talmslagy,Inc. proposes gY 6 ' Y � ' PP <br /> "clean" soil. Following any soil excavation, a minimum number of confirmation samples <br /> 5900He11a so-9et will be required, regardless of the pre-characterization results and observations of"clean" <br /> Suite A soil. <br /> li nyvilla.CA 94608 <br /> Tel(S10)620-0700 <br /> Fax(310)470.9170 <br />
