Table 5-2 (DHS TABLE A) QUANTITIES OF MANIFESTED WASTE GENERATED IN SAN JOAQUIN COUNTY IN 1986 (Continued) 1 . Manifest data were compared for 1985 and 1986. In cases where 1986 data were lower than 1985 data, manifests were reviewed and the relevant generators contacted. For these cases, generators indicated that 1986 data were more representative than 1985 data. Two waste groups, waste oil and pesticides, were responsible for the major difference between 1985 and 1986 data. See footnotes 4 and 5 for details. 2. To avoid double counting waste manifest data, route hauler quantities were subtracted and quantities of hazardous wastes manifested out of state were added to column 1 . This procedure reflects DHS directives. 3. The DHS Primary Generalized Treatment was selected for all but the contaminated soils group. See DNS Technical Reference Manual , Table E-1 and Section 5.2.2 in the text for discussion. 4. In 1985, 394.70 tons of waste oil were manifested, compared to 147.52 tons in 1986. This reduction resulted from fewer generators manifesting waste oil in 1986 compared to 1985 and by a drop in the amount of oil mani- fested. In 1986, Sharpe Army Depot, which serves as a collection center for waste oil from other bases, gener- ated only 8 tons (rounded data) of waste oil , compared to 61 tons in 1985. In addition, Western Pacific merged with Union Pacific in 1986. Together the two railroad companies generated 60 tons in 1986, compared with 116 tons in 1985. 5. In 1986, the quantity of pesticide wastes manifested in the County was 1 ,379.09 tons, compared to 3,657.80 tons in 1985. The unusually large quantity of pesticide waste generated in 1985 was due mainly to the significant amount of pesticide-contaminated runoff at the site of J.R. Simplot Company. Since the Simplot firm is closing their pesticide operation, the 1986 data are more representative of typical pesticide quantities. PJ9 9390502B.00D 5-22 Rev. 0 11/10/88
