WASTE DISCHARGE REQUI EM£NTS -9- <br /> FORWARD INCORPORATED <br /> WASTE MANAGEMENT FACILITY <br /> CLASS II LANDFILLS <br /> CLASS III LANDFILLS <br /> CLASS II SURFACE IMPOUNDMENT <br /> CLASS. II LAND TREATMENT UNIT <br /> SAN JOAQUIN COUNTY <br /> "SHREDDER WASTE MONITORING", the shredder waste may be disposed <br /> of in a monofill dedicated to shredder waste or in an area where <br /> the shredder waste will not contact other wastes or leachate or <br /> be overlain by wastes other than shredder waste. <br /> S. The discharge of liquid andsemi-solid waste to the surface Impound- <br /> ments is limited to leachate from the landfill unit and surface <br /> impoundment LCRSs; septage, chemical toilet waste, boiler blowdown <br /> water, grease trap pumpings, and other wastes that are compatible with <br /> the liner system and meet the approval of the Board. <br /> 5. Waste materials shall be confined to the waste management units as <br /> shown on Attachments 8, C, and 0. <br /> 7. The Discharger shall remove and relocate any wastes discharged at this <br /> site in violation of this Order. <br /> S. Wastes shall not be discharged below an elevation of +15 feet above <br /> mean .sea level (MSL) . A minimum separation of 30 feet shall be <br /> maintained between wastes or leachates and the highest anticipated <br /> elevation of underlying ground water including the capillary fringe. <br /> 9. All wells located within 500 feet of a waste management unit shall be <br /> sealed to the satisfaction of the San Joaquin Local Health District <br /> prior to the discharge of waste to the unit. A record of the sealing <br /> and/or abandonment of such wells shall be sent to the Board. <br /> GENERALCONSTRUCTION <br /> 10. Materials used to construct liners shall have appropriate physical and <br /> chemical properties to ensure containment of discharged wastes over <br /> the operating life, closure, and post-closure maintenance period of <br /> the WMUs. <br /> 11. Materials used to construct leachate collection and removal systems <br /> (LCRS) shall have appropriate physical and chemical properties to <br /> ensure the required transmission of leachate over the life of the <br /> WmUs. <br /> 12. Clay liners and landfill caps shall have a minimum hydraulic <br /> conductivity of 1x1O-6 cm/s and a minimum relative compaction of 90 <br /> percent. Hydraulic conductivities of liner materials shall be <br /> determined by laboratory tests using solutions with similar properties <br /> as the fluids that will be contained. Hydraulic conductivities of cap <br /> materials shall be determined by laboratory tests using water. <br />
