The excavation was filled with clean material from a quarry site; <br /> information concerning amount, type, & source of material has not <br /> been furnished to us. <br /> Sept.& Oct_ , 1994 - A 1,000 gallon waste oil tank was removed <br /> from a site just north of the shop & adjacent paint booth & wash <br /> rack by Jim Thorpe Oil, Inc; (refer to ELATE X11 for it' s <br /> location. ) Soil samples were collected at 10' below grade from <br /> the east & west end of the excavation, & the spoil pile_ The <br /> samples were analyzed for BTEX, TPH-G, purgable halocarbons, <br /> semi-volatile organics, TEPH, & CAM-TTLC, 10 metals. The results <br /> of those analyzes revealed very minor amounts of Xylene in two <br /> samples, diesel, motor oil, very minor amounts of some semi- <br /> volatzes, and no purgable halocarbons. The excavation was filled <br /> with clean material, & the spoil pile moved to a site adjacent to <br /> the removed diesel tanks. Laboratory results of those analyzes <br /> are included as MWIDIT E. <br /> Thorpe Oil then removed a 10,000 gallon, a 5, 000 gallon, & a <br /> 3,000 gallon UST which had contained diesel fuel. They were <br /> located in a open area about 1.00' east of the shop building; <br /> . refer to PLATE XIII for details of their locations & sample <br /> points. Laboratory results revealed very minor amounts of <br /> Ethylbenzene & Xylene in one sample from the west end of the <br /> 10,000 gallon tank, 6,000 mg/kg of TPH as diesel in that sample, <br /> 90 mg/kg from the sample at the east end of the 5, 000 gallon UST, <br /> 22 mg/kg of TPH--D in a sample at 4' beneath the line connecting <br /> the two sets of tanks, and EB, Xylene & TPH--D from the product <br /> lane Analysis of samples from the spoil piles revealed only <br /> TPH-G & motor oil . Copies of the laboratory sheets are included <br /> as EXHIBIT F. The excavations are currently open; spoil is stored <br /> as shown on PLATE XIII, and they are protected by an 8' high <br /> chain link fence. <br /> The four tanks were removed under permits obtained from the San <br /> Joaquin County EHD, & work was witnessed by a representative of <br /> the County. Permits, tank tracking records & other documents are <br /> included as EXHIBIJ G_ The results of any additional work that <br /> may be required by the County will be included in later reports. <br /> WQRKPLAN FOR SOIL &^ GROUN- ATER INV$S11GATION: <br /> The following workplan is for placing three (3) soil borings as <br /> shown on the enclosed PLATT. XIV programmed to approximately 35' <br /> below grade, or to the water table_ Soil samples will be taken & <br /> analyzed at 5 foot intervals from 5' bgl to the capillary fringe, <br /> and discrete water samples will be taken by driving a hydropunch <br /> or similar device into the groundwater. Soil boring #8 will be <br /> completed as a groundwater monitoring well as described below. <br /> 5 <br />
