WASTE DISCHARGE REQUIREMENTS -10- GOLDEN GATE FRESH FOODS, INC. VICTOR FINE FOODS TRchTMIEi"T PLANT Air"v CLASS II SURFACE IMPOUNDMENT SAN JOAQUIN COUNTY POND OPERATION EESB Construction Specifications 10. Materials used to construct liners shall have appropriate physical and chemical properties to ensure containment of discharged wastes over the operating life, closure, and post-closure maintenance period of the EESB. 11. Materials used to construct the LCRS shall have appropriate physical and chemical properties to ensure the required transmission of leachate over the life of the EESB and the post-closure maintenance period. 12. The LCRS shall be designed, constructed, and maintained to collect twice the anticipated daily volume of leachate generated by the WMU and to prevent the buildup of hydraulic head on the underlying liner at any time. The depth of fluid in the LCRS sump shall be kept at six inches, the minimum needed to ensure efficient pump operation. EESB Supervision and Certification of Construction 13. The equalization/emergency storage basin shall have a double synthetic liner with an intervening blanket type LCRS. The outer synthetic liner shall be 40 mil , high density polyethylene or equivalent material . The inner synthetic liner shall be 60 mil , high density polyethylene or equivalent. 14. The equalization/emergency storage basin shall be designed, constructed, and operated to maintain a freeboard of 12 feet. In the event that the activated sludge portion of the treatment plant and/or the injection well are down for maintenance or repairs wastewater may be diverted to and held in the EESB for up to 30 days or until the freefoard reaches 2 feet plus that needed for the 100-year return wet season. Immediately after such a event water levels must be lowered at a minimum rate equal to 3 days for every day of diversion. At no time shall the freeboard in the EESB be less than twelve feet for more than 90 consecutive days. 15. All discharges to the equalization/emergency storage basin shall have fail-safe equipment or operating procedures to prevent overfilling. 16. The EESB storage basin shall be designed, constructed and maintained to prevent scouring and/or erosion of the liner(s) and other containment features at points of discharge to the impoundments and by wave action at the water line.
