1� <br /> B. Excavation Technique <br /> For the initial stage of the excavation, the excavated soils <br /> will be removed by a track hoe and stockpiled on-site on <br /> plastic tarps. If additional excavation is needed, the <br /> s. soils will be loaded directly onto Awaiting trucks. <br /> 1 , <br /> C. Site Control <br /> R,y The entire site is surrounded by perimeter fencing to <br /> prevent unauthorized access. <br /> D. Shipment <br /> tc <br /> The transportation of the excavated soils will be by proper- <br /> ,.:, ly licensed and certified hazardous waste haulers. The <br /> 4L exterior of the trucks will be thoroughly cleansed prior to <br /> leaving the site to avoid possible migration of soil from <br /> the site. The trucks will be cleansed by brushing all <br /> visible dust and soil off the vehicles onto plastic ground <br /> cover. At the conclusion of the excavation project, any <br /> soil cleared from the trucks along with the plastic ground <br /> E� cover will be placed in the last truck to leave the site. <br /> All trucks will be covered with a waterproof tarpaulin to <br /> prevent soil dispersion during transit. <br /> All soils shipped with TPH concentrations <br /> greater than 1000 <br /> a,.r. mg/kg will be documented by hazardous waste manifesting <br /> �.. �' procedures. All soils shipped with TPH concentrations less <br /> than 1000 mg/kg will be documented by bills of lading. For <br /> disposal and shipping, San Joaquin County's EPA generator <br /> identification <br /> number will be documented on the shipping <br /> manifest. San Joaquin County has a current EPA generator <br /> number on file with the EPA and State of California. <br /> �z3 <br /> { E. Disposal <br /> E <br /> ci All soils containing greater than 1000 mg/kg TPH will be <br /> disposed of in a Class 2 disposal site. soil containing <br /> � g less than 3,000 mg/kg of TPHwill be delivered locally for <br /> land spreading at the Stockton, Forward, Inc. site. <br /> F. Confirmation Sampling and Analysis <br /> At the completion of the excavation to the dimensional <br /> limits shown on Figures 3 through 5, four soil samples will <br /> € ' be taken from along the perimeter of the excavation. One <br /> ho sample at each of the four locations will be taken 5' above <br /> the excavation bottom. Samples will be collected from <br /> equally spaced distance around the perimeter of the excava- <br /> tion. The samples will be collected via the track hoe scoop <br /> and containerized outside of the excavation. The samples <br /> will be in lab prepared lass ars with teflon lids.
