within the active compost will be monitored daily using hand-held temperature <br /> probes. This information will be recorded and records maintained at the facility. <br /> Moisture content will be monitored based on knowledge of incoming moisture content, <br /> moisture addition, and by manual and laboratory testing. Piles will be watered and/or <br /> turned based on the results of monitoring. All operating standards defined by State <br /> composting regulations will be followed. <br /> As the materials in the active compost age, the volume of the compost decreases. <br /> Windrows will be combined with neighboring Windrows to maintain the desired pile <br /> dimensions. <br /> The final material will be screened according to market specifications. Screened <br /> material will be stockpiled on the site prior to loadout to markets or for on-site uses. <br /> Oversized materials (overs) from the screening process will be reground, sold, or <br /> landfilled. <br /> b. Quench or Process Water <br /> Describe water supplies for process water required and planned method of <br /> treatment and disposal of any wastewater(14 CCR, Section 18227(k). <br /> Describe the facilities water supply and irrigation system that will be used at the compost <br /> piles, vessels, grinders, mixers, etc. <br /> The water collected in the runoff retention pond will be used as process water to <br /> meet the desired moisture contents for composting. Water from the retention pond will <br /> be applied to the waste, on an as needed basis and as available, as it leaves the tub <br /> grinder. A fixed nozzle will spray the water on ground waste at the discharge of the <br /> conveyor from the tub grinder. This process will eliminate the potential for pathogen <br /> regrowth in the active compost. The nozzle will not require contact with a human <br /> operator. A pump system will be required to move water from the retention pond to the <br /> tub grinder area. The rate of application of water will be determined to provide the <br /> desired final mixture moisture content. <br /> It is anticipated that the retention pond will provide adequate process water supply. <br /> However, if necessary, process water may be obtained from other on-site sources. <br /> Water for facility operations is supplied by two on-site production wells: a 1,000-gpm <br /> well near the landfill entrance facilities and a 20-gpm well near the RRF building. An <br /> approximate 8,000-gallon water tank will be located in the South Area near the Compost <br /> Facility operations area. Water uses include site construction and waste disposal <br /> operations, RRF/Compost Facility operations, dust control, equipment maintenance <br /> operations, sanitary facilities, fire fighting, and emergency situations. <br /> C. Preprocessing Procedures <br /> Describe any preprocessing procedures (bioreactors, etc.) used to lower availability of <br /> heavy metals in compost. <br /> Preprocessing will include inspecting the incoming material to remove any visible <br /> contaminants. Loads will be visually inspected at the RRF/Compost Facility and will be <br /> manually sorted once they are dumped at the receiving and processing area. A <br /> magnetic separator will be provided to extract nails and other ferrous contaminants <br /> Forward Composting Facility RCSI <br /> 7/20/09;Page 38 SWT Engineering <br />
