Page 3 <br /> the former waste oil tank overexcavation were analyzed for <br /> TPH-gas, TPH-diesel, Total Oil and Grease (TOG) according to <br /> EPA Method 3550, Volatile Organic Compounds according to EPA <br /> Method 8240, Semi-volatile Organic Compounds according to <br /> EPA Method 8270 , and ICAP Metals according to EPA Method <br /> 6010 . A copy of the analytical laboratory reports and Chain- <br /> of-Custody forms are presented in Appendix A. Analytical <br /> summaries are found in Tables A, B and C . <br /> SOIL EXCAVATION AND REMEDIATION <br /> Waste Oil Tank Excavation <br /> Approximately 140 cubic yards of soil was overexcavated in <br /> the vicinity of the former waste oil tank location. The <br /> waste oil tank excavation measured approximately 16 feet by <br /> 14 feet by 16 feet deep ( figure 3 ) . Soil samples WX-1B, WB- <br /> 1A and WB-2A were collected during overexcavation activities <br /> as verification of remediation effectiveness . Final sidewall <br /> and bottom samples were designated WXX-1 through WXX-5, WBB- <br /> 1 and WBB-2 (figures 2 and 3 ) . The sample depths are listed <br /> in Table A with the analytical summary data for the waste <br /> oil overexcavation. <br /> UST Excavation <br /> The overexcavation around the former fuel UST complex was <br /> approximately 75 feet long by 45 feet wide at the longest <br /> and widest sections , and approximately 35 feet deep. An <br /> estimated 1600 cubic yards of soil were removed from this <br /> area during excavation. The approximate location and extent <br /> of the excavation is shown on figures 2 and 4 . <br /> Twenty seven verification samples (TX-1 through TX-27 ) were <br /> collected from the sidewalls of the overexcavation to define <br /> the lateral extent of hydrocarbon impacted soils . Similarly, <br /> eight samples (TB-1 through TB-8 ) were collected from the <br /> bottom of the overexcavation to define the vertical extent <br /> of hydrocarbon impact. Sample locations are shown in figures <br /> 2 and 4 . The depths for each sample collected are listed in <br /> analytical summary Table B. <br /> Product Piping and Pump Island Excavation <br /> Overexcavation around the former product piping area, <br /> originally represented by sample P-1 in TD' s report dated <br /> March 31 , 1993, was approximately 3 1/2 feet by 12 feet by 5 <br /> �) 1/2 feet in depth. Soil sample designated PX-1 was collected <br /> in the bottom of the trench . During removal of the concrete <br /> pad west of the western most former pump island, staining <br /> and hydrocarbon ordors were observed. This area suspected to <br />
