Four staff are currently required to apply PGM; one for the loader, two for the haul trucks, and one for the dozer. Spreading and compacting of the day's wastes prior to application of daily cover will be consistent with the procedures established in the facility's JTD. The PGM is loaded onto haul trucks, which then dump the material on or directly adjacent to the working face requiring daily cover. The green material is placed over the waste and compacted to provide a cover with a minimum compacted thickness of six inches and an average compacted thickness no greater than 12 inches (a 12-inch thick layer was assumed for purposes of calculating the associated refuse to cover ratio). Dozer(s) are used to evenly spread the PGM. The operator will take adequate steps to ensure that processed green material cover will not be exposed to the elements for more than 21 days. Odor and moisture infiltration are also addressed by utilizing 100 percent soil cover on days proceeding non-operational days. If more material comes in than is required for the day, the material is stockpiled onsite and processed and used, as needed. PGM is generally processed within 7 days. Geosynthetic Blanket and Panel Products (Tarps): During daily landfill operations, the size of the working face will be maintained at a size five (5) to ten (10) feet smaller for each dimension as compared to the size of the ADC panel total area. When more than one panel is utilized, they will be overlapped a minimum of three feet and secured. After properly compacting the waste, the tarp is placed over the exposed refuse. The panel(s) is (are) placed on the exposed refuse face in the evening. Three staff are required to place the tarp(s). A dozer is used to raise the tarp in the air and then two laborers unroll and position the tarp. The current tarp size is approximately 65 feet square feet. The tarp(s) is (are) anchored along the edges and across the center. The ADC will be removed the following morning in the same manner and stored away from the active face. The same number of staff are utilized to remove the tarp. A dozer is used to hold the tarp in place and two laborers then re-roll the tarp. The tarp will be removed within 24 hours and the exposed waste will either be covered with new waste or with approved cover materials. Securing the Synthetic Tarp. The tarp will be secured with either soil, sandbags, tires or other heavy items, which have no sharp edges. Depending on site conditions tires, sandbags, or other similar items will be placed in a grid pattern Forward Landfill JTD 6-9 J:\Allied\Forward\JTD Amendment\March 2006 JTD-LEA Resp\JTDUTD Sec 6 Rev.doc: 5/22/02;Rev. t:7/2002:Rev.2:4/2003;Rev 3:6/2003;Amendment No.t:5/22/2006
