1-8 <br />Alternat ive 2. 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+P9. This capacity is based on the following <br />assu m ptions: <br />• Six-day per week operations. <br />• Up to approximately 8 acres for compost Windrows. <br />• New Ww indrows are approximately 154:8 feet wide at the base with approximately 8 <br />feet between Windrows for water addition and fire control. <br />• New wW indrows are approximately 128 feet high. <br />• Composting period is projected to be approximately 4 to 12 weel-<s 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 />p,cm'ide aR estimate of the aRtie/pated avemge dailj' throtJghpldt of the ,facility irJ toRS. <br />Inc/f:Jde the caleu/at/oRS Idsed to determirJe these capacities.
