1-5 <br />Forward Composting Facility SWT Engineering <br /> Report of Composting Site Information - July 2014 <br />z:\projects\allied waste\forward\resource recovery facility\5 yr permit rvw 2013-14\rcsi 2014\text\sec 1.doc <br />land. The permitted maximum daily throughput for the Compost Facility is 1,100 tons, <br />however, actual throughput, including volume of each feedstock, will depend on the <br />composting technology and the availability of the feedstock. Feedstock tonnages will not <br />exceed 100,000 tons annually without prior notification and approval of the LEA. <br />1.3.1 Maximum Daily Load Capacity <br />The permitted maximum daily throughput for the Compost Facility is 1,100 tons per day <br />(tpd) as allowed under SWFP No. 39-AA-0020. The maximum daily load capacity to the <br />Compost Facility will depend on the composting technology employed. Forward chooses to <br />operate with windrow composting using a windrow turning machine. The maximum daily <br />load capacity for this option is presented below. Additional options may be investigated in <br />the future, if necessary. <br />Windrow Composting Using a Windrow Turning Machine <br />The maximum daily load capacity of the Windrow Compost Facility using a windrow turning <br />machine is approximately 1,100 tpd. This capacity is based on the following assumptions: <br />♦ Six-day per week operations. <br />♦ Up to approximately 8 acres for compost windrows. <br />♦ New windrows are up to approximately 15 feet wide at the base with approximately 8 <br />feet between Windrows for water addition and fire control. <br />♦ New windrows are up to approximately 7 feet high. <br />♦ Composting period is projected to be approximately 4 to 12 weeks depending on <br />product desired. <br />♦ 40 percent volume reduction after composting. <br />Figure 4 depicts the windrow composting using a windrow turning machine option. The <br />facility design capacity is discussed in Section 1.3.4 and calculations are included in <br />Appendix B. <br />Sufficient space to store materials during peak operating periods without infringing upon <br />traffic flow or equipment operation is available at the facility. In instances of emergency <br />situations where the inflow rate could be increased and/or additional waste storage is <br />needed, the LEA is contacted to coordinate the best procedures to minimize potential short- <br />term environmental nuisances and public health issues and complaints. During periods of <br />peak loading, the unloading area may be expanded to accommodate higher hourly inflow <br />rates and minimize the potential for customer traffic stacking out onto Austin Road. The <br />vehicle queuing/stacking area leading up to the scales and fee booth is sufficient and <br />proven adequate during peak loading. Additional manpower and equipment will be <br />available, as needed, during periods of peak loading. At no time will the site exceed the <br />1,100 tpd (for the Composting Facility) or 8,668 tpd (for the combined Forward Landfill, <br />RRF, and Composting Facility) permitted maximum for all wastes and materials. <br />1.3.2 Average Daily Throughput <br />The combined maximum tonnage for the Forward Landfill, RRF, and Composting Facility is <br />46,080 tons per week (not to exceed 8,668 tpd). The total permitted throughput for the <br />RRF is 3,080 tpd and as previously mentioned, the total maximum daily tonnage for the
