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, aerated static piles, a combination <br /> of Windrows/static piles, or enclosed agitated beds. 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 carrying waste materials will be directed by to the RRF and will unload in the <br /> appropriate area. Vehicles delivering green waste material that has been <br /> preprocessed (ground) prior to arriving at the Compost Facility or materials that do <br /> not need processing will be directed to a separate unloading area to bypass grinding <br /> operations. Compost Facility personnel will direct vehicles and supervise the unloading <br /> operations. <br /> qW <br /> After the wastes are unloaded, laborers will remove unacceptable wastes such <br /> as plastic bags and miscellaneous pieces of mixed waste from the material. <br /> Loads of material that have been processed prior to arriving at the Compost <br /> Facility will be visually inspected to ensure that contaminants are removed prior to <br /> composting. In addition, large concentrations of materials, which may be difficult to <br /> process or compost, may be segregated from incoming material and routed for <br /> disposal. Difficult-to-process materials include palm and other vinelike materials, <br /> which can cause increased equipment maintenance and downtime; and eucalyptus, <br /> straw, and redwood, which take a long time to decompose and may contain <br /> phytotoxic components. Unacceptable wastes and large concentrations of difficult <br /> materials will be stockpiled onsite and transferred to an appropriate landfill for <br /> 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 /> Forward Composting Facility <br /> Z:\PROIECTS\Allied Waste\Forward\Resource Recovery Facility\Permitting Services\2009 RCSI\RCSI Final 031609.doc; <br /> Page 43 <br />
