Re-excavation/resampie steps: At this time Jim Thorpe Oil, on behalf <br /> of Raymond Investment Corporation, is requesting a re-excavation/resample <br /> to Hopefully remove any remaining traces of gasoline contamination. We <br /> propose to excavate, an area starting 3' north of the existing wall, extending <br /> east and west 3' from the existing wall to a point 5' south of the existing <br /> wall to a maximum depth of 11'. Total proposed excavation is 14' wide x <br /> 22' long x 11' deep. The total amount of additional excavated soil will be <br /> approximately 169 cubic yards. All spoils will be placed on plastic and <br /> covered with same in the area Immediately west of the excavation. Soil samples <br /> i will be taken by the above properly licensed facility from the teeth of the <br /> hoe bucket with brass tubes. Samples will be taken in the appropriate places; <br /> 2 from the bottom of the excavation and 2 from the middle of each side wall <br /> for a totai of 10 samples, Soil samples will be analyzed for RTX R E and <br /> TP11-G. Sidewall sample depths will start at 15' and the second sample will <br /> be taken at 101. (See attached B drawings g ._, C and D for proposed excavation, <br /> r ! resample and spoils locations). Soil remediation plan will be submitted <br /> subsequent to analysis results. <br /> We also plan to take two composite samples from the spoils pile and analyze <br /> as above. . <br /> 8.
