The tarps are removed from the surface of the <br />working area at the beginning of each work day, and replaced at the end of the day. <br /> <br />After delivery to the active face, refuse is spread in lifts approximately two feet thick in an area of <br />approximately 100 feet x 90 feet, or other dimension appropriate for the tarp or other cover. <br /> <br />Refuse fill is controlled by GPS, following a surface design by County staff. Computer screens in <br />the bulldozer and compactor inform the operators of their horizontal and vertical location in <br />relation to the surface design. <br /> <br />Waste is placed within the working area until the end of the day, when the refuse is covered with <br />tarps or soil. If the maximum local height is reached during the day, then soil cover is placed over <br />the refuse at that final elevation, and refuse placement is begun at an adjacent area, also with the <br />fill guided by GPS and the fill surface design. <br /> <br />Large and bulky wastes are separated to prevent bridging of the surrounding refuse. These items <br />are placed in the lower portion of the advancing lift, and crushed by compacting equipment. <br />Temporary soil berms are constructed where needed to intercept and divert surface runoff water <br />away from the working face.
