i <br /> 1 ' <br /> 3.0 Field Activities <br /> Field activities included excavating approximately 80 cubic yards of soil from the , <br /> location of the former 2,000 gallon gasoline UST (East Excavation), and 4 <br /> approximately 250 cubic yards of soil from the location of the for'mee 1 ,000 gallon <br /> waste oil UST (West Excavation). The East Excavation removed approximately 40 <br /> cubic yards of hydrocarbon impacted soil, and approximately 40 cubic yards of "clean" <br /> overburden material. The excavation reached a depth of 15 feet BSG. The West <br /> Excavation removed approximately 150 cubic yards of hydrocarbon impacted soil and <br /> 100 cubic yards of "clean" overburden soil. This excavation reached a depth of 20 feet <br /> BSG. The excavations are shown on the Site Map included as Exhibit 2. <br /> 4.0 Excavation Procedures <br /> On September 16 and 17, 1992, Jim Thorpe Oil performed excavation operations <br /> using a John Deere 690C excavator and a John Deere 410C backhoe. The "clean" <br /> overburden material was removed first, field screened, stockpiled 30 to 40 feet from <br /> the excavation, and covered with visquene. The "clean" material consisted of the j <br /> upper 6 feet from the East Excavation and the upper 4 to 5 feet from the West <br /> Excavation. The contaminated soil was temporarily stockpiled adjacent to the <br /> excavations, and also covered with visquene. This soil will be transported to an <br /> apor priate landfill, and the disposal procedures will be discussed in the final report. <br /> A temporary fence was erected around the excavations. <br /> 4.1 Field Screening of Soil <br /> Soil was collected from the excavator bucket near the teeth and then placed in a <br /> mason jar to approximately 50%.capacity, shaken and stored for a period of 15 <br /> minutes. The top of the mason jar was then pierced, and analyzed with a Foxboro <br /> Model 128 OVA/GC Flame-ionizing detector (FID). A standard headspace reading <br /> was collected at this time and noted. When field observations of stain and odor, and <br /> FID-readings from the base and sidewalls indicated "non-detect", confirmation soil <br /> samples were collected. <br /> 4.2 Confirmation Soil Sampling (First Round) <br /> Confirmation soil samples were collected on September 16 and 17, 1992 <br /> (immediately after excavation), at the locations selected by the on-site County <br /> representative as the most likely to contain the greatest hydrocarbon concentrations <br /> 5 of 10 <br />
