I� Two soil samples were taken at a depth of lit feet, from the north and south ends of the tank locations respectively Ml NR; and TK2 NR S) . Two (2) line samples were also taken, L piping 1 at 51 , 18' from the south edge: of the excavatc+in and piping 2 at 31 , under the former pump island l ocat i+_+n (see map #5) . Fear cOrap+asits were taken from the spoil pile before it was returned to the excavation. 'Sample analyses results showed detectable quantities of TPP--diesel in all samples, TK1 S-2300 mg/kg, TK1 N•--1100 rag/kg, TKA' S-24C) rag/kg, TK2 N--120 rng/kg, piping 1--2700 rag/kg, piping 2--140 wig/kg and the compos i t s SF11 , 2, 3 and 4 showed a combined t i_+t a 1 +--+f 900 rilg/kg. Detectable levels of B. E. T. R X were found in samples TM N, Total Xylenes--44 ug/kr]. TK1 S, ug/kcq, Ethyl : . Denaene-330 ug/I<g and Total Xylene?-9P_(') ,ag/k.g.

All samples were analyzed using California DOFIS LUFT method for diesel / 3550 and constituent volatile aromatics, Bent6nt*, Ethyl Benzene, Toluene and Total Xylene (BETX) using USEPA Test Method 8021) (!gee sini l sample analyses chart ) . Soil real+::+ved from the cCALth0aR5t and northeast corners of the tank locations showed signs of sr._+i l discoUnrcrt ion and had an odor of petroleum. There was no obvious sign of contamin- ation ontamin-ation on' the west side of the excavation. Based Upon the results of soil sample analyses, concentra- tions ontentr'a-- tion+s of TPH and ,the volatile aromatics present in the tank and pipeline Eiresr�-s, additional site characterization and/or, remediation will :'be required for closure. G. Remediation Steps C+_-ncre t e Inc. has retained WM. Hunter and Associates Registered Geole7r)ists and Jim Thorpe Oil, Inc_. to undertake the next phases +nf this cleanup prOject. After consultation with GJPHS/EHD, Wm. Hunter and Associates and Jird Thorpe Oil, Inc. , Concrete Inc. has decided to remove as much of the contamination remaining beneath the tank pit L area as passible by over excavation. The proposed excavation will start approximately 5 feet north of the north end of the original excavation and extend si-nuthward a distance of approximatc--ly 40 -feet. The new excavation will extend 2o feet in an easterly direction from the western boundry of the cirginal tank locition. The plan is to excavate to a depth of 20 feet and slight ad.jctstwents, up or down, made: if necessary. The resulting excavation will be appy!�xiniately 20 feet wide by 40 feet long by 18 to lir feet deep (sec- drawings 02 & 3) . Pipeline excavation will be necessary as the piping :samples indicate c=ontamination along the: product line route. This contamination will be removed by excavating a trench eight (8) feet deep and eight (8) feet wide along the path of RECEWE ED APP 2 'S' 19�
