Soil Analysis <br />Soil samples will be extracted from the bottom and sides of the excavation at a rate of one sample for <br />each 100 square feet of exposed surface. Soil samples will be transported under ice in standard BX <br />sample tubes designed for the use. Each sample tube will be capped with aluminum foil or Teflon sheet <br />and sealed with duct tape. Samples will be transported under ice to an approved state certified <br />laboratory for analysis. Samples will be analyzed by EPA methods 8020 (BETX), and 5030/LUFT <br />(TPHgasoline) & 3550/LUFT (TPHdiesel). Stockpiled soil may be subject to addition analysis as <br />required by the PHS-EHD and Foothill Engineering. <br />Recommended Action Levels <br />Excavation will continue until exposed soil yield analysis results of less than 100 mg/Kg for method <br />5030 & 3550/LUFT. <br />Excavation Backfill <br />Excavation will be backfilled to original grade with suitable, non-contaminated fill material. <br />Schedule <br />The excavation will require two days to complete and the anticipated start will occur on or <br />about December 1, 1998. Hauling of soil will be completed by February 15,1999. All work will <br />be completed by March 1, 1999. <br />Please consider this proposed work plan at the earliest opportunity. If any questions arise, please contact <br />this office @ (209)368-9381. <br />Respectfully submitted,
