2-5 <br /> Curing and Screening. Following composting, the mixture may be screened or placed in <br /> stockpiles up to approximately 12 feet high and approximately 30 feet wide at the base for <br /> curing. In curing, a slower rate of decomposition occurs. A curing time of approximately 1 <br /> to 6 months is needed. An even longer curing period is desirable for production of a higher <br /> quality compost. The curing period will depend on the quality desired and this in turn will <br /> depend on the market or final use of the product. Therefore, the capacity of final compost <br /> output decreases significantly to produce a higher quality compost product. After curing, <br /> the material may be screened. Screening produces a higher quality material, but at <br /> additional cost. Oversized material from screening may be returned for grinding, recycled to <br /> be used in the compost mixture or landfilled. <br /> Alternative Processing. The windrow turning/processing discussed above has been <br /> determined to be at optimum. In the event of equipment breakdown, Republic will <br /> replace/rent a windrow turner. If this equipment is not available, front end loaders will be <br /> used to turn the windrows. <br /> Compost Quality. The decision on what quality of compost to produce will depend on the <br /> available feedstocks, potential markets for compost, and the overall economics of the <br /> composting process. Potential uses/markets for the compost are as follows: <br /> ♦ Bulk agricultural use; <br /> ♦ Wholesale to topsoil manufacturers; <br /> ♦ Tun`farm; <br /> ♦ Farm land reclamation; <br /> ♦ Wholesale to landscape industry; and <br /> ♦ Retail to individuals. <br /> 2.1.3 Facility Construction <br /> The operation of the Compost Facility will be coordinated with operation of the existing RRF <br /> and landfill facilities. Unloading of materials requiring processing (i.e., material screening <br /> and/or grinding) will be done west of the RRF building, as shown in Figure 2. Handling of <br /> wood waste, green material, and agricultural wastes will be similar to the existing wood <br /> waste handling procedures. <br /> The existing conditions plan, legal property limits, and topography are shown in Figure 2. <br /> Except for some setbacks, internal roads, the South Fork easement, and County of San <br /> Joaquin right of way for Austin Road, virtually the entire South Area is developed for <br /> composting (including some of the area now occupied by the RRF). The easement and right <br /> of way are shown in Figure 2. A detailed Site Plan, including the unloading, storage, <br /> processing, parking and loading areas, and ancillary facilities, is shown on Figure 2. <br /> Storage Areas. To the extent feasible, the incoming compostable materials are mixed into <br /> compost piles the same day as received. The storage time of compost feedstock is 72 <br /> hours. <br /> Parking Areas. Visitor and employee parking are on the east side of the RRF building as <br /> shown on Figure 5. <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 />
