1-6 Windrow Composting Using a Windrow Turning Machine The maximum daily load capacity of the Windrow Compost Facility using a windrow turning machine is approximately 1,100 tpd. This capacity is based on the following assumptions: • Six-day per week operations. • Up to approximately 8 acres for compost Windrows. • New windrows are !!l2.1Q __ approximately 15 feet wide at the base with approximately 8 feet between Windrows for water addition and fire control. • New windrows are !!Q..1Q....approximately I~ feet high. • Composting period is projected to be approximately 4 to 12 weeks depending on product desired. • 40 percent volume reduction after composting. Figure 4 depicts the windrow composting using a windrow turning machine option. The facility design capacity is discussed in Section 1.3.4 and calculations are included in Appendix B. Sufficient space to store materials during peak operating periods without infringing upon traffic flow or equipment operation is available at the facility. In instances of emergency situations where the inflow rate could be increased and/or additional waste storage is needed, the LEA is contacted to coordinate the best procedures to minimize potential short-- term environmental nuisances and public health issues and complaints. During periods of peak loading, the unloading area may be expanded to accommodate higher hourly inflow rates and minimize the potential for customer traffic stacking out onto Austin Road. The vehicle queuing/stacking area leading up to the scales and fee booth is sufficient and proven adequate during peak loading. Additional manpower and equipment will be available, as needed, during periods of peak loading. At no time will the site exceed the 1,100 tpd (for the Composting Facility) or 8,668 tpd (for the combined Forward Landfill, RRF, and Composting Facility) permitted maximum for all wastes and materials. 1.3.2 Average Daily Throughput The combined maximum tonnage for the Forward Landfill, RRF, and Composti ng Facility is 46,080 tons per week (not to exceed 8,668 tpd). The total permitted throughput for the RRF is 3,080 tpd and as previously mentioned, the total maximum daily tonnage for the Composting Facility is 1,100 tpd. The average load capacity that will be received will vary with the maximum throughput of 1,100 tpd (for the Composting Facility), as discussed in Section 1.3.1. The current quantity being processed is a fraction of the maximum loading. Forward intends to develop the market for organic materials and increase the quantity of materials composted depending on the demand in the marketplace and ability to use the composted product. The specific materials to be composted will depend on a number of factors: • Availability of materials delivered to Forward • Avai lable markets or end use of compost produced • Specific ratio of materials and compatibility in development of compostable mixtures (I.e., moisture content, Carbon:Nitrogen [C:N] ratio, porosity, etc).
