Page 2-9 SECTION 2- SITE OPERATIONS PLAN <br /> (and operations/dumping pad in) a corner of the new cell. After construction,the landfill operator <br /> should regularly inspect the access ramps for signs of subgrade failure (pumping). Should severe <br /> pumping occur, the geomembrane must be checked for damage. <br /> The initial waste layer (i.e. the waste placed directly on the liner drainage layer) must consist of <br /> select waste. The select waste will be free of large, sharp or protruding objects (such as rebar, <br /> nails, 2 x 4s, etc.) that could be forced through the geomembrane. On-site landfill personnel <br /> should assist in screening and removing or repositioning waste that could damage the <br /> geomembrane. <br /> Refuse collection trucks will remain on the operations pad when discharging the first loads of <br /> select waste onto the liner. It is recommended that when several loads have been discharged, <br /> the operator push refuse out on the liner with a tracked dozer. When a three to four foot thick <br /> bed of select refuse has been placed over the liner, the tracked dozer may safely move over it, <br /> and continue building the first lift. Maximum compaction is not the main goal for the first five feet <br /> of refuse. Instead, compaction should be sufficient to support subsequent refuse lifts, but <br /> minimized to protect the liner. Three passes with the tracked dozer over select refuse that is at <br /> least three to four feet deep should accomplish these goals. Maximum refuse compaction will <br /> be a desired goal once several feet of select waste have been placed over the liner. <br /> A minimum of five feet of select waste must cover the geomembrane and sand drainage layer <br /> before the waste compactor is allowed into the new cell. Until the five foot minimum is met, the <br /> tracked dozer will be used to place and compact the refuse. <br /> A minimum of five feet of compacted, select refuse must cover the geomembrane and drainage <br /> layer before a road can be built on the refuse to accommodate truck traffic. At that time, a <br /> minimum six inch thick, 26 foot wide (minimum) layer of on-site clean sand and gravel will be <br /> placed over the refuse to serve as the road bed. The edge of the road will be clearly marked to <br /> keep traffic from leaving the roadbed. <br /> Filling of the new cell will begin at the operations pad, working "up" until a road can be <br /> constructed on the refuse. At this point, the operation will begin working "down" to place the first <br /> lift of refuse. (That is, the refuse will be dumped from the road on top of the first lift of refuse and <br /> then pushed down the slope onto the liner system). All other lifts will be placed working "up." <br /> 2.1.7.2 Waste Unloading and Compaction Procedures <br /> To reduce the amount of blowing litter, vehicles should use an L-shaped dumping method. This <br /> L-shaped method consists of unloading the refuse along the toe of the previously constructed cell <br /> perpendicular to the working face (which creates the long leg of the "L") and along the toe of the <br /> advancing working face (which creates tlhe short leg of the "L"), as shown in Figure 2-2. The <br /> compaction equipment then pushes the refuse from each leg to the working face where it is <br /> spread and compacted. <br /> R.W.Back and Associates <br /> C::y of Stocxton 1811 002 <br />
