San Joaquin Street • P. O. Box 388 • Stockton, CA 95201-0388 <br /> 209/468-3420 <br /> C (0 <br /> JERYL FRY <br /> MOHR FRY RANCHES <br /> 12609 N WEST LANE <br /> LODI CA 95240 WED JUN 2 21995 <br /> RE: MOHR-FRY RANCHES SITE CODE: PROO1152 <br /> 950 INDUSTRIAL <br /> STOCKTON CA 95206 <br /> San Joaquin County Public Health Services, Environmental Health Division (PHS/EHD) has <br /> reviewed the June 2, 1995 "Workplan for Soil Sampling at Former Acetone Tank Area" <br /> prepared by Cypress Environmental on behalf of Universal Rundle Corporation for the above <br /> referenced site. <br /> The workplan states that due to uncertainties in the actual depth of the former tank pits, samples <br /> for chemical analysis will be collected approximately 5 feet below the reported excavation <br /> depths. A review of the tank removal inspection report by PHS/EHD staff indicates that the <br /> sample depth in tank 1 was 15 feet for sample 1W, 15.5 feet for sample 1E and 2.5 feet for the <br /> pipeline sample. Sample depth in tank 2 was 17 feet for both the North and the South sample. <br /> Figure 2 of the workplan shows the relative locations of the two proposed borings and the <br /> location of the former waste acetone tank. The text of the workplan says CE-1 will be drilled <br /> near the east end of former product Tank 1 and CE-2 will be drilled near the north end of <br /> former waste acetone Tank 2. PHS/EHD concurs that these proposed locations will resolve the <br /> question of contamination located near T1-E taken July 18, 1989 and T1-N taken December 20, <br /> 1989. <br /> A review of the tank removal results by PHS/EHD staff indicates that contamination is also <br /> present at the west end of former product Tank 1 as indicated by the results of the analysis of <br /> T1-W taken July 19, 1989 and the pipeline between the former dispenser and the former fill end <br /> of Tank 1 as indicated by the results of the analysis of P1 taken July 19, 1989. PHS/EHD staff <br /> has determined that these areas are not addressed in this workplan. <br /> The workplan was discussed during the meeting of June 14, 1995 by all parties involved. The <br /> agreed upon changes to the workplan are two additional borings CE-3 and CE-4 and the <br /> sampling depths in all the borings. CE-3 is to provide confirmatory analysis of the former <br /> pipeline area. One sample is to be taken from a depth of 3.0-3.5 feet below grade. CE-4 is to <br /> provide confirmatory analysis of the former west end of the product acetone tank. The samples <br /> are to be obtained from a depth of 17 and 22 feet. CE-1 is to be sampled at 17 and 22 feet. <br /> Boring CE-2 is to be sampled from 20 and 25 feet. <br /> A Division of San Joaquin County Health Care Services <br />
