WASTE DISCHARGE REQUIREMENTS ORDER NO.R5-2014-0006 -g- FORWARD INC.AND REPUBLIC SERVICES INC. FORWARD CLASS II LANDFILL SAN JOAQUIN COUNTY c. the leachate shall not exceed the moisture holding capacity of the receiving unit. This section of Title 27 also references State Water Board Resolution 93-62 regarding liquids restrictions in 40 C.F.R. section 258.28 for MSW landfills. 40 C.F.R. section 258.28 states that liquid waste may not be placed in MSW landfill units unless the waste is leachate or gas condensate derived from the landfill unit and it is designed with a composite liner and an LCRS. Therefore, leachate and landfill gas condensate from composite lined units with an LCRS may be discharged to composite lined units with similar classification. Forward has multiple composite lined units constructed with the same general design and with the same classification. This Order includes requirements for returning leachate and landfill gas condensate back to composite-lined units such that it is not exposed to surface water runoff, will not cause instability of the landfill, and will not seep from the edges of the units. SURFACE IMPOUNDMENTS 25 Liquid wastes will be discharged to one of two existing (F-North and F-West) and one proposed Class 11 surface impoundments. If leachate production exceeds impoundment capacity at any impoundment, excess leachate will either be contained in temporary on-site, above ground tanks or will be transported to the City of Stockton's wastewater plant for off- site disposal. No liquids generated offsite will be discharged to the impoundments without is prior approval of the Central Valley Water Board Discharges to Class II surface impoundments included the following: a. Leachate from the landfill units and surface impoundments; b. Landfill gas condensate from the LFG extraction system; c. Impacted storm water runoff from the landfill and associated facilities; d. Cannery rinse water; and/or e. Other liquid wastes that are compatible with the liner system and approved by Board staff. All Class II surface impoundments LCRSs are tested annually. 26.Facility Specification C.7 requires that the Discharger operates the Class II impoundments so that on October 15 of each year a freeboard of at least 4.73 feet and 5.51 feet exists in F- North and F-West, respectively. This corresponds to two feet plus the calculated rise in liquid level associated with an average annual storm season. Facility Specification C.8 of these WDRs requires that the Discharger manage liquid levels in the impoundment in accordance with a Board staff-approved operations plan under Title 27. COMPOST FACILITY WASTE 1925.The Discharger proposes to continue to treat some decomposable organic waste in the 1 Compost Facility. Material accepted for treatment at the compost Facility includes green
