Title 14, Chapters 3 and 5 of the California Code of Regulations which relate to solid waste disposal at the site. This involves review of this and other engineering and permitting reports for the site and also site inspection to verify compliance with CIWMB regulations. In July 1988, an ASWAT was performed at the site to comply with Health and Safety Code, Section 41805.5. As mentioned in Section D, above, the SJVUAPCD approved the ASWAT. The SJVUAPCD has recently adopted Rule 8010 to control various sources of fugitive dust, including landfill operations. The San Joaquin County Department of Public Works has complied with this new rule. VI. CONCEPTUAL DEVELOPMENT PLAN The conceptual development plan for the Foothill Sanitary Landfill is contained in the January, 1994 "Preliminary Closure Plan" (PCP) for the site. This plan includes drawings titled, "Foothill Sanitary Landfill Preliminary Closure Plan". The Preliminary Closure Plan is contained in appendix C of the 1995 Report of Disposal Site Information. A. Site capacity and operational life: Estimates of waste capacity, earthwork, soil cover requirements and site life according to the PCP are shown in Table 1. The refuse capacity is approximately 102, 116, 000 cubic yards of compacted waste including daily cover. Estimated site life is 61 years or the year 2055. This was calculated using 1994 waste quantities for a base year and applying an annual increase of 5% for population growth. The gate volume for each year is adjusted for the effects of AB 939 which require diversion of 25% of the waste stream by 1995 and 50% by 2000. Finally, the resulting waste quantity is adjusted to in-place volume by applying a compaction factor. A list of assumptions used to prepare the table follows the table. B. Earthwork and location of soil borrow pits: The Foothill Sanitary Landfill will be developed in modules. Sheet 3 of the PCP shows the sequence of modules to be developed. As each module is being filled, the next module will be used for borrow soil. C. Surface drainage, erosion, and sedimentation control: Surface drainage will be as shown on the Final Grading Plan (sheet 2 of the PCP) . Erosion will be controlled by maintaining gentle slopes to reduce water velocity. Sedimentation will be controlled by constructing a series of sedimentation basins around the perimeter of the site. Further information regarding drainage is contained in section III E. D. Leachate control and monitoring: 19
