WASTE DISCHARGE REQUIREMENTS -3- FRENCH CAMP LANDFILL CITY OF STOCKTON SAN JOAQUIN COUNTY 16. The 100-year, 24-hour precipitation event for the facility is 3.8 inches. 17. Surface drainage is to Walker Slough and to French Camp Slough, which are tributary to the San Joaquin River. 18. The beneficial uses of surface waters are municipal and domestic supply, agricultural supply, industrial process supply, ground water recharge, recreation, navigation, and freshwater habitat. FACILITIES OPERATION/DESIGN 19. The area fill method is used at the site for current operations. The remaining landfill capacity will be filled in a similar manner but is proposed to be developed in four modules. In Module I, filling will take place behind a screening berm, starting in the southernmost section of the module, and will advance in a northerly direction until the module is filled to final slope grade. Modules 2, 3, and 4 will be filled in 10-foot-thick lifts to final slope grade. 20. The Discharger's current plans indicate that the Limited Class III landfill will reach capacity, at the earliest, by the year 2010. The site has a projected additional capacity of 1.45 million cubic yards. 21. The Storm Water Pollution Prevention Plan (SWPPP) calls for a single sedimentation pond to be constructed adjacent to French Camp Slough, southeast of the landfill. Stormwater runoff would collect in a perimeter ditch and flow to the sedimentation pond. The pond would discharge to French Camp Sough after it has reached capacity. 22. The natural geologic materials between the base of the landfill and ground water may not prevent the impairment of beneficial uses of ground water from the discharge of non-hazardous solid wastes to the landfill during operation, closure, and the post- closure maintenance period. FINANCIAL ASSURANCES 23. The Discharger has obtained and maintained assurances of financial responsibility for initiating and completing corrective action for all known and reasonably foreseeable releases from the waste management units. Such assurances or funds for corrective action consist of a cost estimate for cleaning up all known or foreseeable releases from the landfill and a Certificate of Self-Insurance and Risk Management.
