AGE-NC-07-1517 17 March 2008 Page 2 of 7 The area of soil excavation and soil samples are depicted on Figure 4.A total of approximately 100 cubic yards were removed during the two excavation events. 2.2.1 Soil Excavation Soil was excavated by L&B Environmental,Inc.of Stockton,California(L&B Environmental)with a backhoe. The northeast excavation areal dimensions were approximately 64 feet in length and 18 feet in width. The southeast excavation areal dimensions were approximately 28 feet long and 15 feet wide at its widest point. Based upon laboratory reported lead concentrations of soluble lead within sample NEWS2 which exceeded hazardous waste criteria, the northeast excavation area was extended approximately 2 feet further west on 01 February 2007.Hazardous-waste soil from both the northeast and southwest excavation areas was segregated into a soil stockpile,pending appropriate disposal at a Class I landfill. The remaining soil was stockpile for disposal at a designated waste landfill (Class II). All soil stockpiles were placed on plastic and covered with plastic. 2.2.2. Soil Sampling and Analysis On 06 December 2007,utilizing a metric slide-sampler or by hand-packing,an AGE representative collected 18 soil samples from the both the northeast and southwest excavation areas and two soil samples from the segregated soil stockpile under the oversight of EHD. On 07 December 2007, an AGE representative collected a total of three soil samples from the two stockpiles remaining to be sampled. These samples were used to determine the appropriate landfills for disposal. Soil samples NEB 1 through NEB4 were collected at approximately 2 feet bsg from the center of the floor of the northeast excavation area from approximately 12 linear feet from the north sidewall (NEB 1)equi-distant apart to approximately 12 linear feet from the south sidewall(NEB4).Samples NEB 1 and NEB4 were collected at former sampling points AA and BB, respectively. Soil samples NENS and NESS were collected at approximately one foot bsg from the northeast excavation area north and south sidewalls,respectively. Soil samples NEWS 1,NEWS2 and NEWS3 were collected at approximately one foot bsg from the north,middle and south sections of the west sidewall of the northeast excavation area,respectively. Soil samples NEES 1,NEES2 and NEES3 were collected at approximately one foot bsg from the east sidewall north, middle and south sections of the northeast excavation area, respectively.
