rill Tire SACRAMENTO Letter to Mr. Richard McCombs January 5, 1988 Page 4 covered to prevent rainwater from washing hydrocarbons onto the surrounding soil , or to prevent the escape of unpermitted air emissions. According to Mr. Harlin Knoll of the San Joaquin County Local Health District, a soil sample from a depth of 40 feet was taken for :laboratory analysis by Jim Thorpe Oil, Inc., during the week of December 21,'1987. The result of the laboratory analysis was not available at the time of this report; however, Mr. Knoll added that contamination was visibly identifiable in the sample from 40 feet. Mr. Knoll indicated that an investigation determining the lateral and vertical extent of the contamination would most likely be required prior to determination of necessary cleanup actions. A 500-gallon underground gasoline storage tank was also removed during January, 1987. The gasoline tank was located along the northern edge of the distilling material storage building {see Photo 2, Attachment II). The gasoline storage tank was constructed of steel, and the age is unknown. According to Jim Thorp: oil, Inc., at the time of excavation the soil sampled below the gii;oline storage tank contained no hydrocarbon contamination. After the laboratory results had been received, the tank excavation pit was backfilled. A copy of the tank removal permits are included as Attachment III. According to Mr. Beck, neither of the tanks were ever integrity tested. A 104-gallon above-ground tank was located on the northwest corner of the concrete operations yard. The tank appears to have contained solvent for cleaning equipment. No secondary containment structure is evident around the tank, however, no evidence of contamination was identified. Three wastewater ponds are located on the northern edge of the site. The westernmost pond is used for rainwater runoff from the concrete facility operations yard. The center pond was used for distillery slop material and process equipment cleaning wastewater (see Photo 3, Attachment II) The easternmost pond was an overflow pond and, according to the plant manager, was never utilized. During certain times of the year, excess wastewater in the central pond was pumped across the river to the 20-acre pond. According to the plant manager, the ISC winery held no permits for the discharge of the wastewater to the ponds. According to Mr. Alien Biederman of the San Joaquin Local Health District, in 1984 the ISC winery was ordered by the Regional Eater Quality. Control Board to submit a complete characterization of their wastewater discharge in order to prepare a discharge plan. There is no --- -- - ---record-of-any-such-reporting. - -- -- - = Versar collected two surface soil samples for laboratory analysis. One sample, BSI-87-3, was collected from the central wastewater pond at a depth of 1'.5 to 4.0 inches. Another sample, BSI-87-4, was collected
