• Nylander Equipment Charter Way Stockton 6.3.3 EQUIPMENT PREVENTATIVE MAINTENANCE Besides the daily maintenance (checking belts and fans, engines, hydraulic oil, fuel, blowing down dust, etc.), the landfill and transfer station have a preventive maintenance program that routinely schedules all heavy equipment for servicing based on the number of hours the equipment has been in service (250 hours, 500 hours, 750, 1000 hours, etc.). 6.4 MATERIAL HANDLING ACTIVITIES 6.4.1 CONSTRUCTION PHASING The base grading plan for the Forward Landfill (Drawing 3) shows the WMU excavations that will provide refuse fill capacity and soils to support landfill operations. The base of each future WMU excavation will be lined and an LCRS will be constructed over the liner before any waste is placed. The site phasing plan (Drawing 5) presents the order in which the WMUs will be developed and Drawing 4 shows the final landfill grades. For more details see Section 5.2.5. 6.4.2 UNLOADING Trained landfill personnel direct vehicles to the unloading area and maintain control over the area used for discharging wastes. Shipments of waste requiring special handling such as designated wastes, ash, Asbestos-Containing-Wastes (ACW), or sludge, are directed to their respective disposal areas. Since all shipments of waste are scheduled in advance, the site traffic is controlled and there is minimal stacking, if any. 6.4.3 SPREADING AND COMPACTION The landfill is constructed by the area fill method. The waste cells are approximately 150 feet wide, and refuse is placed in lifts of 10 to 20 feet. Wastes are tipped and spread in approximately 2-foot thick layers, and then compaction equipment traverses the waste several times on the active working face.
