Richard Springer, .P.E. Borden, Inc. 1050 Kingsmill Parkway Columbus, Ohio 43229 � Bear Mr. Springer, Please find arsclosed the: analytical :data report for the eleven samples collected from, the soil stocki.les rpt 'the iLaura Scudder's Tracy facility located at 100 W. Valpiao Road,, TraQy, California. The collection of these samples was done at the direction of the San Joaquin County Environmental Health Department, Environmental Health Division. The sample collection locations and number of samples were left to the .County,s cliscretion. Of these eleven samples, .six were collected from stockpile T? which is comprised of soils excavated from the area of the former underground diesel storage tank identified previously as tank T2 . Three samples were collected from the'. stockpile identified as FB which consists of soils collected froth the excavated flower bed. area along the northeastern property line. The remaining two samples were collected from a stockpile labeled ' UNlocated immediately west, outside the fence, &� the former truck-wash area at the southern end of the property. The origin of this stockpile is unknown. All of the soil samples were analyzed for the heavy fraction Petroleum Hydrocarbons (TPH) The heavy fraction TPH are recorded in the analytical data report'. as diesel #l, diesel #2 and jet fuel. The jet fuel designation is used for petroleum hydrocar- bons of a heavier fraction than diesel #2 such as diesel #6 and motor oil . Additionally, the two samples from the VNK stockpile were analyzed for the light fraction TPH. The analytical reaults, presented in tabular form � on;. Table 1, indicate detectable concentrations of heavy fraction TPH in all but three samples. The concentrations, while being low; are not of the range for which these piles may be land applicated without further treatment. Therefore, two alternatives for the soil disposition are available to Horden, Inc. at this time. These 'alternatives are 1) on-site $eratibn Of the 'stockpiled soils or 2)' off-site soil' disposal . The aeration of the soils on-site can be acoomplished' by: obtaining a permit from the San Joaquin County Environmental Health, Division, Air Pollution Control Division. Once the permit has been received, the soils can be spread into a thin layer on an impervious surface with a mixture of organic compost. i° This will allow natural aeration as well as microbial degradation to occur. However, due to the nature Of the compounds detected (heavy fraction TPH) , this 3
