KI iLE1NFELDER <br /> SOIL ASSESSMENT WORK PLAN <br /> AMERICAN MOULDING AND MILLWORK F LCILITY <br /> STOCKTON, CALIFORNIA <br /> 24-220182-B00 <br /> August 6, 1992 <br /> INTRODUCTION <br /> American Moulding and Millwork Company (AMM) is located approximately 40 acres <br /> at the intersection of Alpine Street and West Lane in Stockton, C ' ornia (Plate 1). AMM <br /> acquired this facility from American Forest Products Company AFPC) in 1987. AFPC <br /> operated a lumber remanufacturing facility at the site from 1921 to 1987. AFPC purchased <br /> lumber from other mills and produced finished products, including furniture kits, cut stock, <br /> agricultural boxes, and moldings. <br /> AMM is considering debt refinancing and wishes to investigate s veral areas at this time. <br /> The following scope of work outlines Kleinfelder's proposed dr lling locations, sampling <br /> protocol, and analytical analyses for the burn pit investigation. <br /> SCOPE OF WORK <br /> Task 1 - Drilling and Sampling of Four Borings <br /> Four borings will be drilled at the approximate locations shown n Plate 2. The borings <br /> will be drilled to a depth of approximately 30 feet. Soil borings will be advanced using a <br /> truck-mounted drill rig equipped with 6-inch hollow stem augeis. The borings will be <br /> drilled, logged, and sampled following the protocol described in A ftachment A, Sections A- <br /> 2.1 through A-2.4, and closed as described in Section A-2.7. <br /> Task 2 - Laboratory Analysis <br /> One soil sample from each boring will be selected for laboratory a clysis. The samples will <br /> be selected based on field observations, qualitative screening results, and the objectives of <br /> the investigation. The four soil samples will be submitted to a laboratory certified by the <br /> State of California Department of Toxic Substances Control (I)TSC) for the proposed <br /> analyses. The samples will be analyzed for: <br /> ► Extractable total petroleum hydrocarbons (TPH); <br /> ► Polychlorinated byphenols (PCBs); <br /> ► Metals (chromium, lead, nickel, and zinc) by ICP <br /> In addition, two of the four samples will be analyzed for halogenated volatile organic <br /> compounds. Each of the samples will be analyzed on a regular turnaround schedule, <br /> usually requiring 15 working days for completion. <br /> FAT-92-16 Page 1 of 3 <br /> Copyright 1992 Kleinfelder,Inc. <br />
