i 6y VVV <br /> 6.0 <br /> MANAGEMENT OF INVESTIGATION DERIVED WASTE <br /> The contamination assessment scope of work is limited and is directed at ascertaining if leakage <br /> of diesel fuel has occurred. Cuttings generated from borings which are not submitted as <br /> environmental samples will be placed back in the borehole. The remaining borehole space will <br /> be filled.by collapsing the surrounding soil or filling with nearby surface soil on site. It is <br /> anticipated that a maximum of 0.6 cubic feet of soil will be generated during investigation <br /> activities. Approximately one quarter to one half of this volume will be submitted to the <br /> laboratory for analyses. <br /> Decontamination procedures are detailed in the sampling plan. Decontamination fluids will <br /> consist of tap water, deionized water, alconox soap and materials removed from sampling <br /> equipment during decontamination. These fluids are anticipated not to exceed five gallons. The <br /> fluids will be examined for a petroleum sheen and screened with the Photovae Snapshot PID <br /> for VOC's. If no sheen or VOCs are evident, the fluids will be poured on an impervious <br /> surface on site, such as asphalt or concrete, and allowed to evaporate. When possible, the fluids <br /> should belaced inside the secondary ary containment for the AST. If a sheen or VOCs are <br /> detected,;the fluids shall be placed on a sealed 5-gallon bucket and labeled unclassified waste <br /> with the date and point of contact. The fluids shall remain on-site until analytical results are <br /> available. <br /> L <br /> L' <br /> P. <br /> 8054 cA8054Ucjax.gap 10 <br />
