The waste materials will be formed into compost piles/beds, approximately 18 feet high, <br /> approximately 18 feet wide, and of varying length (up to approximately 300 feet long). The <br /> active compost will be mixed as required for proper control depending on temperature <br /> and moisture profiles and season (turning will be kept to a minimum during the rainy <br /> season). The frequency of the Windrow turning and water addition will be determined by <br /> monitoring the pile temperature and moisture content. Temperatures within the active <br /> compost will be monitored daily using hand-held temperature probes. This <br /> information will be recorded and kept in the RRF office. Moisture content will be <br /> monitored based on knowledge of incoming moisture content, moisture addition, and by <br /> manual and laboratory testing. Piles will be watered and/or turned based on the results <br /> of monitoring. All operating standards defined by state composting regulations will be <br /> 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 material <br /> will be stockpiled on the site prior to loadout to markets or for on-site uses. Oversized <br /> materials (overs) from the screening process will be reground, sold, or landfilled. <br /> b. Quench or Process Water <br /> Describe the anticipated volume of quench or process water required and <br /> planned method of treatment and disposal of any wastewater[14 CC18220(1)]. <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 be <br /> applied to the waste, on an as needed basis and as available, as it leaves the tub grinder. <br /> A fixed nozzle will spray the water on ground waste at the discharge of the conveyor from <br /> the tub grinder. This process will eliminate the potential for pathogen regrowth in the <br /> active compost. The nozzle will not require contact with a human operator. A pump <br /> system will be required to move water from the retention pond to the tub grinder <br /> area. The rate of application of water will be determined to provide the desired final <br /> 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 site operations is supplied by two on site production wells: a 1,000-gpm well <br /> 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. Water uses <br /> include site construction and waste disposal operations, RRF operations, dust control, <br /> equipment maintenance operations, sanitary facilities, fire fighting, and emergency <br /> situations. <br /> Forward Composting Facility <br /> p g <br /> Z:\PROJECTS\Allied Waste\Forward\Resource Recovery Facility\Permitting Services\2009 RCSI\RCSI Final 031609.doc; <br /> Page 44 <br />
