a. Waste Handling and Separation Describe plans for waste handling and separation. Describe control and monitoring for maintenance of proper moisture content and temperature. Vehicles carrying waste materials will be directed by to the RRF and will unload in the appropriate area. Vehicles delivering green waste material that has been preprocessed (ground) prior to arriving at the Compost Facility or materials that do not need processing will be directed to a separate unloading area to bypass grinding operations. Compost Facil- ity personnel will direct vehicles and supervise the unloading operations. r After the w ° _,.are unloaded, laborers will remove unacceptable wastes such as plastic bags and misceaheous pieces of mixed waste from the material. Loads of material that have been processed prior to arriving at the Compost Facility will be visually inspected to ensure that contaminants are removed prior to composting. In addition, large concentra- tions of materials, which may be difficult to process or compost, may be segregated from incoming material and routed for disposal. Difficult-to-process materials include palm and other vinelike materials; which can cause increased equipment maintenance and downtime; and eucalyptus, straw, and redwood, which take a long time to decompose and; may contain phytotoxic components. Unacceptable wastes and large concentrations of difficult materials will be stockpiled onsite and transferred to an appropriate landfill for disposal. After personnel have removed unacceptable and/or difficult materials and large wood ob- jects from the waste which requires grinding, a front-end loader will feed the waste into the grinder or move the material within reach of a grapple that will load the grinder. The grinder will shred the material into pieces with a nominal diameter of 3 inches or less. After the material passes through the grinder, it will be dropped onto a conveys that moves the material past a magnetic separator. A magnetic separator will be provited to extract nails and other ferrous contaminants from the material. The shredded waste will be 1 moved by the front-end loader to the composting area or loaded into a dump truck that will transport the material to the composting area where it will be combined with other waste feedstock. The waste materials will be formed into compost piles/beds 8 feet high, 18 feet wide and P P g , of varying length (up to 300 feet long). The active compost will be mixed as required for proper control depending on temperature and moisture profiles and season (turning will be kept to a minimum during the rainy season). The frequency of the Windrow turning and water addition will be determined by monitoring the pile temperature and moisture content. Temperatures within the active compost will be monitored daily using hand-held temperature probes. This information will be recorded and kept in the RRF office. Mois- ture content will be monitored based on knowledge of incoming moisture content, moisture addition, and by manual and laboratory testing. Piles will be watered and/or turned based on the results of monitoring. All operating standards defined by state composting regula- tions will be followed. wa10029B5C.W'P 5/61 9/29/94 61
