® crushed by compacting equipment. Temporary berms are constructed where needed to <br />intercept and divert surface runoff water away from the working face. <br />The procedures for disposing of municipal solid waste include vehicles entering east <br />through the gates to the scale house. After entering the site vehicles follow signs toward <br />the active landfill face. After each vehicle unloads they proceed back to the scale house to <br />weigh and pay. <br />After waste is deposited at the active face, it is moved by dozers and bladed compactors to <br />its final resting spot. The compactors spread and compact the wastes by making repeated <br />passes over an area. As the process is repeated, each lift of waste receives a number of <br />passes of the compactor which increases the density of the waste. The dozers are used to <br />assist the compactors in moving wastes to meet the rate of disposal. The operators <br />observe disposed refuse for un -permitted and hazardous wastes. Procedures are <br />established for removing these wastes from the fill area before covering. <br />• The direction of filling in each module will be detailed in the design report for the module <br />and will be based on refuse fill stability. Operational issues, such as the direction of access <br />to the module will also be considered in assessing the refuse fill directions for each module. <br />In general, refuse filling in a module will begin on the same side as the boundary with the <br />previous module. Also, refuse filling will occur in uniform lifts between the side slopes to <br />reduce the refuse loads imparted on side slope lining systems. <br />6.3. Cover <br />6.3.1 Cover Materials <br />Currently, daily cover material is obtained by excavating from the area of the next <br />planned module or from the existing stockpiles (Figure 5). The Foothill Sanitary <br />Landfill site is expected to have sufficient soil for cover, including closure <br />(Tables 3 and 4). <br />The -operator currently uses cover soil at a refuse to soil ratio of approximately 4:1. <br />0 <br />Foothill Sanitary Landfill Page 37 of 57 Public Works/Solid Waste <br />Joint Technical Document County of San Joaquin — Revised 7/30/10 <br />
