materials used at the site for ADC. The site also uses synthetic tarps and tires for ADC. All ADC material used is compacted to the required thickness in accordance with 27 CCR. 4.3.2 TRAFFIC LIMITATIONS Forward will maintain records of incoming loads and vehicle counts and will limit deliveries of wastes for disposal and other materials for beneficial reuse to a total of 620 trips/day and to the maximum inflow rates described above. It should be noted that delivery of waste and other materials varies on a daily basis. Therefore, on days when less waste is received, the site may accept more loads of the beneficial reuse materials. If the receipt of beneficial reuse materials exceeds the site needs on a given day, then the material will be stockpiled. When stockpiling of material is required, the material will be placed so as not to interfere with the daily landfill operations, in accordance with 27 CCR, Section 20660. Records are maintained of all beneficial use materials accepted and how these materials are utilized on-site. Forward will also track the weight/volume of stockpiled material and report that information to the LEA monthly. 4.4 WASTE INFLOW RATES For the purpose of estimating remaining site life, the estimated annual inflow rate to the Forward Landfill over the next five years is estimated to be approximately 1,871,374 tons, which corresponds to a weekly average inflow rate of approximately 35,987 tons. Actual quantities received may vary from these amounts. The diminishing landfill capacity for the Forward Landfill is included on Table 8. 4.5 REFUSE TO COVER RATIO The Forward Landfill remaining capacity and associated site life are dependent on a number of factors. One of these factors is the refuse-to-cover ratio. The Forward Landfill refuse-to-soil cover ratio (volume) is 4:1 (refuse to cover). Refuse-to-soil cover ratios can range from 3:1 to 5:1. The 4:1 ratio is generally accepted in the solid waste industry as an appropriate ratio for a properly operated sanitary landfill (i.e., a sanitary landfill that does not receive violations for inadequate cover). As discussed above, Forward utilizes a number of other materials which are used as alternative daily cover including, but not limited to, Forward Landfill JTD 4-10 J:\Allied\Forward\JTD Amendment\January 2007 JTD Amendment\JTD Sec 4 Final.doc: 05/24/02;Amendment No. 1: 2/1/2007 BRYAN A.STIRRAT 6 ASSOCIATES
