Interior surfaces of the excavation (UST and piping excavations) will be visually <br /> I inspected for discoloration or staining. The results of the inspections will be documented <br /> Approximately 2 ft of native soil will be removed from beneath the UST for field screening with <br /> a FID and potential analysis. If field screening results indicate petroleum impacted soil at this <br /> depth, excavation will continue untAl field screening indicates less than 50 units on a FID <br /> Confirmation samples will be collected after over-excavation has been completed. <br /> am lin <br /> For planning purposes, the following sampling and analytical tasks represent the minimum level <br /> of effort planned for the project Additional sampling requirements, such as sidewall sampling, <br /> may be completed based on site conditions and requests by EHD <br /> Soil and groundwater sampling of the UST excavations, including the number and location of <br /> samples, and analytical parameters are listed below Theses requirements follow EHD <br /> regulations in conjunction with the RWQCB's, "Tri-Regional Board Staff Recommendations For <br /> Preliminary Evaluation And Investigation of Underground Tank Sites, August 1990." <br /> Ifan roundwater is encountered at time within the tank excavation, it will be sampled at the <br /> g Y <br /> i direction of EHD for the same analytical parameters as the soil samples from the excavation. <br /> i <br /> Unleaded Gasoline T k - 1,000Gallon <br /> One soil sample will be collected from the fill or pump end of the tank excavation and analyzed <br /> for the following analytical parameters <br /> L\PR0JECT5"NJ0QUA1M ACP 12 15 May 1995 <br />
