k' ■ KLEINFELDER concentrates, in areas of former above ground storage tanks (ASTs), tank wash out area, and the residence leach field. A total of seven (7) shallow soil sampling locations have been identified in this section. Please see Plate 2 for sample locations. In accordance with the soil sampling protocols in the City of Manteca, South Manteca EIR, for farm properties proposed for development, the City of Manteca requires at least the following, but it should be noted that this property is not being developed at this time, and this sampling protocol is being implemented due to the lack of specified guidance at this time from regulatory bodies. • "One sample retrieved at random from every 5 acres;" • "One sample from every area identified by records examination as characterized by probable high concentrations of pesticides or pesticide residues;" • "Alternating samples recovered from the ground surface at depths of 1 foot below ground surface, and at depths of 3 feet below the ground surface;" • "A testing program designed to detect threshold concentrations of priority pesticides, including chlorinated hydrocarbons, carbamates and organophosphates;" • "An accounting procedure, in which any instances of contamination discovered during the sampling program are reported to San Joaquin County Environmental Health Department (EHD);" • "A report containing all soil sample test results and locations, as well as recommendations for remediation procedures to be completed under the direction of EHD prior to issuance of development entitlements." The soil samples would be collected by using a hand auger to advance the soil boring to its total depth. When the desired sampling depth is reached a cleaned stainless steel sampler attached to a slide hammer is lowered to the bottom of the boring and driven into the subsurface. The sampling tool is retrieved and the soil sampled is sealed for possible laboratory analysis. 3.2.1 Vehicle Parking Area Within the former vehicle parking area the soil samples would be collected from one location for possible laboratory analysis. The soil samples would be collected at the surface, 1 foot bgs, and 3 feet bgs. A total of 3 soil samples would be collected in this area for possible laboratory analysis. At this time and in accordance with the requirements stated above we propose to submit a total of 1 soil sample for laboratory analysis. The 1 foot soil sample from the vehicle parking area would be submitted for laboratory analysis. The remaining soil samples would be put-on hold at the laboratory pending further analysis requirements if applicable. 3.2.2 Depression Near the Eastern Edge of the Site A depression of the land surface exists near the eastern edge of the site, and was described to Kleinfelder as an area where surface water pools due to run off at the site. Kleinfelder proposes to collect two shallow soil sample from within the depression area for possible laboratory analysis. The soil samples would be collected at the surface, 1 foot and 3 feet bgs. We propose to analyze the 1 foot soil sample at this time. The remaining soil samples would be put on hold at the laboratory pending further analysis requirements if applicable. 27125.E01 /ST03R657 Page 7 of 15 Copyright 2003,Kleinfelder,Inc. May 23,2003
