2-6 <br />Forward Composting Facility SWT Engineering <br /> Report of Composting Site Information - August 2019January 2022 <br />z:\projects\allied waste\forward\resource recovery facility\5 yr permit rvw 2019-2020\rcsi 2019\text\sec 2.doc <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, t he 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 />Processing Areas. The Compost Facility include s areas for receiving, pre compost processing, <br />post-processing, and compost storage. Non-processible materials (residual wastes) will be <br />hauled to the Forward Landfill for disposal at the end of each working day or within 24 hours <br />from the time of receipt . Figure 2 includes a general dimension of the unloading, storage, <br />processing, parking, and loading areas. Design calculations for this area is included in <br />Appendix B. <br />Prevention of the Propagation of Vectors and the Creation of Nuisances. The site will be <br />graded as shown on the grading plan (Figure 6) to promote drainage of surface water from <br />all areas of the site into two ditches that drain to a sedimentation basin. The site will be <br />constructed of compacted native earth. On-site soils are silt and clay, and will provide a <br />relatively impermeable surface. The site will be graded relatively smooth allowing complete <br />removal of deposited feedstock. Feedstock such as food processing residue will be <br />incorporated immediately into compost piles to minimize the chance of vector attract ion and <br />reproduction as well as for odor minimization. Semi-solid and liquid feedstocks will be <br />added to other feedstocks at a rate to meet the composting mixture moisture criteria, thus <br />minimizing the potential for leachate formation. Semi-solid and liquid feedstocks will be <br />incorporated immediately into compost piles to minimize the chance of vector attraction and <br />reproduction as well as the generation of potential odors. Other highly putresible wastes <br />such as grass will also be incorporated immediately into compost to minimize the chance of <br />vector attraction and reproduction and odor production. All feedstocks will be mixed in <br />proportions that promote efficient composting, aerobic conditions , and minimize ammonia <br />odor release. <br />Windrow tTurning and ASP aeration cycles will be scheduled to provide compliance with <br />pathogen reduction requirements and maintain aerobic conditions. <br />Water Usage. Water will be added to the piles, as necessary, before turning to maintain <br />efficient composting. Water will also be used to control dust from the compost pad and <br />various composting operations , such as grinding and screening.
