• Hazardous organic wastes would not be acceptable unless <br /> stabilized or solidified and encapsulated. <br /> 2. The design and operation of the facility would be such as to keep <br /> 9 p y P <br /> the residuals dry as practical to prevent the formation of leach- <br /> ate. <br /> 3. Major cells of a residuals repository would be operated during the <br /> normal dry weather in order to promote drying of the residual <br /> prior to final cover. During periods of rain, temporary sheeting <br /> would be used to keep the cells dry. <br /> In accordance with regulatory requirements, a repository can be sited <br /> only in areas that meet hydrogeologic criteria outlined in Sec- <br /> tion 2531 et. seq. of Title 23 of the California Code of Regulations. <br /> A copy of these regulations is included in Appendix E. This section <br /> of .the Code specifies (among other requirements) permeability of <br /> underlying soils, thickness of underlying low permeability materials, <br /> the need to exclude floodplains, and the requirement of a 200-foot <br /> setback from known Holocene faults. If at some future time the waste <br /> management needs in the County suggest considering siting a residuals <br /> facility, extensive hydrogeologic assessments would be needed of any <br /> candidate areas. <br /> 11 .4 IN SITU TREATMENT OF CONTAMINATED SOIL <br /> Depending on the constituents involved, various in situ treatment <br /> methods (for treating contaminated soils) have been successfully <br /> implemented at a number of locations. Within the County, much of the <br /> 1985 and 1986 contaminated soil has gasoline, diesel fuel , and motor <br /> oil constituents. The following treatment methods can be used for <br /> contaminated soil : <br /> PJ9 9390502D.000 11-19 Rev. 1 11/08/88 <br />
