II. PROJECT DESCRIPTION a high percentage of recoverable materials, would be directed to the processable area. Front- g P g loading or side-loading vehicles carrying source separated recyclables from residential and commercial recycling programs would also be directed to the processable area of the tipping floor. The other incoming trucks, front-end loaders with commercial and residential refuse, would be directed to the non-processable area. At 1,000 TPD,the facility would receive an estimated 100 loads per day in rolloff vehicles (coming from construction sites) and 69 loads per day mainly in front loaders(from residential and commercial routes). The loads of incoming vehicles under 2.5 tons(such as automobiles and small pickups)would be estimated by volume,rather than weighed at the truck scale, and the vehicles directed to the appropriate area of the tipping floor or the green waste pad. In the non-processable area of the tipping floor,one to two floor sorters would be stationed to pull out large recoverable items such as large pieces of wood, metal,cardboard, and white goods. In addition, materials would be recovered by up to six sorters on an elevated sorting platform (discussed below). The non-processable trash would be consolidated and moved from the tipping floor toward the loadout chutes, which extend over a below-grade roadway,using a front loader or similar equipment. The trash would be pushed through the chutes onto top-loading transfer trucks directly below. The project includes a screen and conveyor belt in an enclosed building to sort and recover materials,primarily from C&D wastes. The processable waste would be moved onto an feed conveyor which rises from the floor to a shaker screen and belt approximately 18 feet above ground to the sorting platform. The screen removes dirt and small pieces of plastic,glass,and other debris so that only larger,potentially recoverable pieces of material move onto the conveyor belt. Recyclable pieces of concrete, wood,ferrous and nonferrous metals,paper, and cardboard are picked off the belt by employees stationed at six bays along the belt. Recovered materials would be dropped into rolloff bins situated below the conveyor. When a bin was full, the materials would be transported to off site markets. Non recoverable residuals on the belt would continue back to the loadout area via the"rejects conveyor" shown in Figure II-2. GREEN WASTE The facility would receive approximately 25 loads per day(averaging 6 tons per load)of green waste in various collection vehicles. Vehicles hauling green waste would deposit their loads on a paved green waste pad in the southeastern comer of the site. The pad,which would not be covered,would be equipped with a floor drain connected to the existing site drainage system, which leads to an existing detention pond just east of Pershing Avenue. Using a bucket loader, the green waste would be loaded into a tub grinder at the green waste pad, from which it would be loaded into a rolloff bin. Any rolloffs holding green waste temporarily on site would be parked on the green waste pad. The ground green waste would be transported off site for composting or other uses. No green waste would remain at the site for more than 72 hours. The sources of the green waste would be self haul loads and,potentially, loads now collected every other week by City of Stockton crews (and currently taken to the composting facility at Forward Landfill) under the City's curbside program.
