it 11 ACTIONS TAKEN AT THE ISC WINERY SITE BY JIM THORPE OIL COMPANY BETWEEN SEPTE:NIBER 13, 1955 AND DECE;WEIt 13, 1959 The September 13, 1983. date refers to Appendix A-9, wherein GTI responded to questions from the 511_HD (Appendix A-S) concerning their Preliminary Site Assessment RepDrt of May, 25, 1935 (Appendix A-7) . The first contaminated soil was discovered during the removal of a 15,060 gal . , concrete fuel storage bunker during late 1987 or early 1985. Approximately 4 ,000 cu. yds . of soil were excavated at that time (Fig. 2) , of which about 2 ,000 cu. ' ds. were considered to be contaminated with leakage from the concrete tank (diesel and/or bunker fuel oil ) . The removed spoil was stock- piled on site with all contaminated soil placed initially in Pile 11 i and later in Pile # 2 (Figs. 2 dr 3) . In as much as most of the surface at the site is either covered with concrete foundation slabs or a 6" asphalt topping, spoil could be easily stored without danger of groundwater infiltration . JTO , who was in charge of demolition and cleaning up of the site for ISC, along with other investors, purchased the entire property in July of 1988. According to JTO, buildings around the storage tank area were de- molished during October & November 19SS. Then, about 1250 cu. yds. of non-contaminated spoil were placed on plastic in a pile south of the excavation area (Pile # 3) and about 1400 cu. yds. of contaminated soil were removed and placed on plastic sheeting overlying asphalt north of the excavation (Pile # H . At that time the excavation was about 50' X 75" long and 20' deep. 71, December, 1988 a short work summary and a soil remediation plan was submitted to the DHS by JTO. While waiting for a response to this document , the remaining buildings were demolished in Jan. & Feb. 1989 (Appendix If 10) and most of the building material scrap removed from the site. Some rubble remains today, mostly in the form of concrete chunks and rebar. EXCAVATION In this same report (Appendix 10) , it was proposed to enlarge the excavation to about 75 'X 100' X 40' deep. These dimensions would approximately encompass the area between the outermost test and __.man i.-Lor ing - we I.I_s d.r_i I le-d- by - GTI , wherein no --- - -- ---.. contaminated soil was found. Because the three monitoring wells had not hown the groundwater to be contaminated, it was believed that all contaminated material could be recovered by an excava- tion of this size, estimateo to be about an additional 5,555 cu. yds. of possibly contam nated soil and 27SO yds. of uncontarnina- ted. It was proposed that sampling & testing be done during all 3
