Active faces need to have a certain moisture content <br /> so as to preclude the generation of dust. It Is recognized that a balance must be struck <br /> between maintaining sufccient moisture for dust control and applying too much moisture <br /> such that the generation of=ess leachate occurs. The conditions at the active faces of a <br /> landfall as well as the lewhare generated,shall be monitored and professional judgment <br /> utilized at all tunes to kzep these two factors in balance. <br /> F.HYDROLOGYAND WATER QLL4 LTIY <br /> 44(F.1) <br /> Proposed as Part of the Project: <br /> As part of the design plans for the proposed landfill,Forward Landfill completed calculations <br /> of the 1000-year peak disccLxrges. The hydraulic and drainage study was used to design <br /> appropriate drainage con^-ols. Drainage controls were designed to prevent contact between <br /> surface water and refuse. Size run-on and run-off control facilities consist of drains and <br /> perimeter ditches that cha.=- el surface water to lined holding and evaporation ponds on the : <br /> I <br />
