operating day. If tonnage was figured from records of cubic yards, include the conversion <br /> factor used. Describe provisions to handle unusual peak loadings in accordance with 14 <br /> CCR, Section 18227(i). <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 <br /> to operate with one primary composting technology (Alternative 1) and one back-up <br /> technology (Alternative 2). The maximum daily load capacity for these two alternatives is <br /> presented below. Additional alternatives may be investigated in the future. <br /> Alternative 1. Compost Windrows Turned by Front End Loaders <br /> The maximum daily load capacity for the Windrow Compost Facility turned by front end <br /> loaders is approximately 640 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 /> • Windrows are approximately 16 feet wide at the base with approximately 10 <br /> feet between each pair of Windrows to allow turning using front-end loaders. <br /> • Windrows are approximately 8 feet high. <br /> • Composting period is projected to be approximately 4 to 12 weeks, depending <br /> on product desired. <br /> • Curing period is projected to be approximately 1 to 6 months, depending on product <br /> desired. <br /> • 40 percent volume reduction during composting. <br /> Alternative 2. Windrow Composting Using a Windrow Turning Machine <br /> The maximum daily load capacity of the Windrow Compost Facility using a windrow <br /> turning machine is approximately 1,100 TPD. This capacity is based on the following <br /> assumptions: <br /> • Six-day per week operations. <br /> • Up to approximately 8 acres for compost Windrows. <br /> • Windrows are approximately 18 feet wide at the base with approximately 8 feet <br /> between Windrows for water addition and fire control. <br /> • Windrows are approximately 8 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 /> Forward Composting Facility RC51 <br /> 7/20/09;Page 5 SWT Engineering <br />
