62-701500(2)(f) <br />METHOD AND SEQUENCING OF FILLING WASTES <br />Sequence of Filling Waste <br />Waste Filling <br />The Class I landfill shall be developed in accordance with the operations plan and the <br />operating sequence plan as described herein. The sequence of filling shall also be in <br />accordance with the phasing plan presented in the permit renewal application for <br />Segment 2. <br />Generally, Class I solid waste landfilling is accomplished in 8 to 10 foot high lifts, with <br />the working face progressing across the base of Segment 2 in an east to west direction. <br />A working face of about 100 feet width by 100 feet long is used. The working face area <br />is minimized to reduce infiltration, while providing adequate room for vehicles <br />unloading their solid waste. As of October 31,1995, the SWDD had completed filling <br />solid waste across the entire 26 -acre Segment 2 base, to an elevation of about 60 feet <br />National Geodetic Vertical Datum (NGVD). <br />A terrace has been constructed at elevation 55 feet NGVD by moving the next lift <br />inward 20 feet from the edge. Lift 4 from elevation 55 to 65 has started in the northeast <br />corner of Segment 2, and will advance to the west. Filling of lifts sequence from north <br />to south, in accordance with the approved fill sequence. The working face will be <br />sloped at a 4:1 slope to maximize runoff from the cover material. Diversion berms to <br />route stormwater away from the working face area will consistently be used to <br />minimize infiltration. The Segment 2 top surface will generally be graded to the east <br />and south to route stormwater away from the infill. Additional terraces with a 20 -foot <br />width will be constructed at elevation 75 and 95 feet NGVD.
