2-4 <br /> production well is located along the eastern boundary of the site,just south of the entrance <br /> to the Composting Facility/RRF. The locations of the wells located in the RRF/Compost <br /> Facility area are shown on Figure 2. In addition, water is available from the storm water <br /> runoff sedimentation basins, however this alternative is not currently utilized at the site. For <br /> additional information, refer to Section 3.5.2. <br /> These water supplies are available for initial mixing of the compost to bring the water <br /> content up to desired levels, wetting of the compost, dust control, and other applications <br /> through use of on-site water trucks. <br /> Preprocessing. Preprocessing and initial handling of feedstocks is also common to the <br /> alternatives. Materials with large particle sizes such as wood waste, green material and <br /> agricultural wastes may require grinding before use as feedstock and composting. All <br /> incoming feedstock is spread out for manual screening before being stockpiled. These <br /> materials will be handled in the manual sorting receiving area of the Compost Facility and <br /> ground using a tub grinder. Additional grinding capacity will be added, as necessary, to <br /> handle the volume of green and wood waste material received at the facility. Green <br /> material high in grass will be mixed as soon as possible with ground wood waste and/or <br /> recycled compost and/or other relatively dry and low C:N feedstock to minimize odor <br /> production. Sorting of green and wood waste materials is done only as part of the <br /> composting operation in an area near the grinder. <br /> Any MSW that is mixed in with the curbside greenwaste is removed before composting. In <br /> addition, removal of large objects is necessary to prevent damage to Windrow turning <br /> equipment and grinding will aid decomposition during composting. If a higher quality <br /> product is desired, more extensive pre-processing may be necessary. This could consist of <br /> manual picking of metal, plastics and glass from the incoming material or receipt of clean <br /> source-separated waste. <br /> Grinding and trommel screening of the material prior to composting has significantly <br /> improved the quality of the final compost product. More mechanized processing has <br /> included magnetic and eddy current separation for improved removal of iron and aluminum <br /> components of the waste stream. The decision on the amount of preprocessing will be <br /> determined by economics and the final use of the compost product. <br /> Semi-solid materials such as food processing residue and food waste will be placed on other <br /> materials such as ground green material or wood waste or recycled compost and mixed as <br /> soon as possible to minimize the potential for leachate formation and odors. The amount of <br /> these materials accepted will be limited by the availability of other feedstocks. <br /> Current Design/Processing Option <br /> Windrow Composting using a Windrow Turner. Figure 4 shows the layout for windrow <br /> composting using a Windrow turner. A loader will be used to create the windrows, and a <br /> windrow turner is used to turn the windrows. The windrow dimensions can be up to <br /> approximately 7 feet high and approximately 15 feet wide at the base. The space between <br /> Windrows is about 8 feet to provide access for a water truck for water addition and for fire <br /> control. Windrow composting using a windrow turner is also discussed included in Section <br /> 1.3.1. <br /> Forward Composting Facility SWT Engineering <br /> Report of Composting Site Information-November 2014 <br /> z:\projects\allied waste\forward\resource recovery facility\5 yr permit rvw 2013-14\resi 2014\text\9-nov 2014 track changes\sec 2.doc <br />
