THE REMEDIATION PLAN �.. <br /> Foothill Engineering proposes that the soil remediation be done in two sections to keep the best <br /> possible access to the owner's equipment service area(see attached sketch). The section under over- <br /> excavation will be fenced to protect the public. Surface traffic will be routed around the section under <br /> excavation. The excavation will be limited to a projected slope of 1:1 from the building foundations <br /> as not to endanger the structural integrity of the surrounding buildings. No shoring or foundation <br /> support will be utilized. It is estimated that the first section will yield a volume of+/- 3000 CY of <br /> both contaminated and clean soil. <br /> Both clean and contaminated soil will be stockpiled on plastic sheeting on the west side of the <br /> property. After the actual volume and soil contamination levels are determined, the owner will decide <br /> on disposal or treatment. Contamination levels of excavated soils will be determined by combined <br /> samples. <br /> SOIL SAMPLING <br /> After excavation of each section of the project, confirmation samples will be taken from the sidewalls <br /> and bottom of the over-excavated area. Sidewall samples will be taken at twenty foot intervals. The <br /> excavation floor samples will be taken at random or as ordered by PHS/EHD at a rate of <br /> approximately one sample for every 400 square feet of surface area. <br /> All samples will be taken from excavated material in the excavator bucket or by taken by hand in <br /> place. Standard brass soil sample liners will be used to collect and contain the soil samples. Each liner <br /> will be sealed with aluminum foil, standard plastic cap and duct tape and labeled. All liners will be <br /> placed in individual sealed airtight bags and labeled. Samples will be shipped with ice, under chain-of- <br /> custody to Sherwood Labs, Hilmar, California. <br /> TEMPORARY FENCE <br /> A temporary fence will be placed around the excavation until the excavation is backfilled. <br /> BACKFILLING EXCAVATION <br /> The backfill of each section of excavation will proceed after approval by PHS/EHD. Fill material will <br /> be placed under City of Stockton building permit and to city specifications. <br /> GROUNDWATER MONITORING WELLS <br /> All groundwater monitoring wells that are removed will be replaced after backfill is completed. <br /> TENTATIVE WORK SCHEDULE <br /> Excavation to begin after work plan approval <br /> HEALTH AND SAFETY PLAN <br /> See attached Health and Safety Plan <br /> Respectfully submitted, <br /> Foo ginee QRS g�0�A <br /> Eh�G? <br /> ti <br /> Ervin Ri nbur owner <br /> SCF Cim.1 �' 2 <br />
