I 1 September 1996 " AGE Project No. 95-0108 - ' "Page 6 of 10 3.7. EXCAVATION OF HYDROCARBON-IMPACTED SOIL, NOVEMBER 1994, On 29 November 1994, approximately 100 cubic yards of impacted soil was excavated from the- western portion of the former UST area under the direction of GAS. Excavated soil was stockpiled ti adjacent to the excavation. A total.of five soil samples were collected from the floor and sidewalls of the excavation. Samples . . • were collected using a metric soil sampler �re-loaded with two clean 2-'b 3-inch brass sleeves. Upon collection, the ends of the leading brass sleeve were covered with.aluminum sheets, capped; and sealed with tape. The samples were placed in a chilled container and transported under chain-of- to MAI. All soil samples were P custod ' les ere analyzed for TPH-d.in accordance with EPA-method 8015. •TPH-d was detected in the sample collected from the west wall (WW-l; 28 feet) at a concentration. of 14,000 ppm. Petroleum hydrocarbons were not detected in.the'other samples"collected on 29_. November 1994.. Analytical •results of soil t sar'iples are included in Table 4. The laboratory report(MAI Lab ID 42669 to 42673) and chain-of custody included in Appendix M. 3.8. STOCKPILED SOIL SAMPLING, APRIL 1995 ' On 14 April 1995, a representative of AGE collected ten soil samples from the soil stockpile on site.' Soil samples were collected using a metric soil sampler pre-loaded with two clean 2-by 3-inch brass 'sleeves. Upon collection, the ends of the lead brass sleeve were covered with aluminum sheets, ' capped and sealed with tape. The samples were placed in a chilled container and transported under_ chain-of-custody to MAI. The stockpile samples were composited by MAI into five samples.for analysis of TPH-d and BTE&X. TPH-d was detected in each sample at concentrations as high as 1,110 ppm. Low concentrations of • P g _ ,. toluene and, xylenes were also detected in the stockpile soil samples. Analytical results are summarized in Table 4. The laboratory report (MAI Lab ID 51728 to 51732) and chain-of-custody, M are included in Appendix N. 3.9. EXCAVATION OF HYDROCARBON-IMPACTED SOIL, APRIL 1995 On 25 Apri1,1995, an additional 140 cubic yards of hydrocarbon-impacted soil was excavated from. ' the former UST area, under the supervision of AGE. Four soil samples were collected from the floor ' and sidewalls of the excavation-at depths ranging from 24 to 28 feet bsg. Soil samples were collected using a metric soil sampler pre-loaded with two clean 2-by 3-inch brass sleeves: Upon collection, the ends of the leading brass sleeve were covered with aluminum sheets, capped and sealed with
