3.5.2 Type of Operations <br /> Include the type of operation such as Windrow, static pile, enclosed vessel etc., <br /> and describe a typical operation cycle. Issues which should be addressed include the <br /> amount of waste received (daily, weekly or monthly), frequency of irrigation, aeration, <br /> turning, Windrow pile size, etc. <br /> The Compost Facility will use either the Windrow composting method turned by <br /> front-end loaders or Windrow machine turners.. The facility operations are further <br /> described in the following sections. The amounts of waste received are described in <br /> detail in Section 1.3, Quantity of Materials to be Accepted. <br /> a. Waste Handling and Separation <br /> Describe plans for waste handling and separation. Describe control and monitoring <br /> for maintenance of proper moisture content and temperature. <br /> Vehicles delivering green waste material that has been preprocessed (ground) prior <br /> to arriving at the Compost Facility or materials that do not need processing will be <br /> directed to a separate unloading area to bypass grinding operations. Compost Facility <br /> personnel will direct vehicles and supervise the unloading operations. <br /> After the wastes are unloaded, laborers will remove unacceptable wastes such as <br /> plastic bags and miscellaneous pieces of mixed waste from the material. Loads of <br /> material that have been processed prior to arriving at the Compost Facility will be <br /> visually inspected to ensure that contaminants are removed prior to composting. In <br /> addition, large concentrations of materials, which may be difficult to process or compost, <br /> may be segregated from incoming material and routed for disposal. Difficult-to- <br /> process materials include palm and other vine like materials, which can cause increased <br /> equipment maintenance and downtime; and eucalyptus, straw, and redwood, which <br /> take a long time to decompose and may contain phytotoxic components. <br /> Unacceptable wastes and large concentrations of difficult materials will be <br /> stockpiled onsite and transferred to an appropriate landfill for disposal. <br /> After personnel have removed unacceptable and/or difficult materials and large <br /> wood objects from the waste which requires grinding, a front end loader will feed the <br /> waste into the grinder or move the material within reach of a grapple that will load <br /> the grinder. The grinder will shred the material into pieces with a nominal diameter <br /> of approximately 3 to 6 inches. After the material passes through the grinder, it will <br /> be dropped onto a conveyor that moves the material past a magnetic separator. A <br /> magnetic separator will be provided to extract nails and other ferrous contaminants <br /> from the material. The shredded waste will be moved by the front end loader to the <br /> composting area or loaded into a dump truck that will transport the material to the <br /> composting area where it will be combined with other waste feedstock. <br /> The waste materials will be formed into compost piles up to approximately 8 feet high, <br /> approximately 18 feet wide, and of varying length (up to approximately 300 feet long). <br /> The active compost will be mixed, as required, for proper control depending on <br /> temperature and moisture profiles and season (turning will be kept to a minimum <br /> during the rainy season). The frequency of the Windrow turning and water addition will <br /> be determined by monitoring the pile temperature and moisture content.
