Recyclable materials which will be removed from the Tipping/Sorting Floor will be deposited in roll off bins. When full,the 40 CY bins will be moved from the "Z wall" at the south end of the tipping/sorting floor and staged in the Recycling Storage Area for removal off-site. The County will provide trucks and drivers for staging and limited removal of full bins. Private recycling companies will haul a portion of the recovered materials. The amount of recyclable materials recovered will determine the need for frequency of removal. Projections for recycling under the proposed hand and loader sorting on the tipping floor will depend upon the composition of the waste stream and the efficiency of sorting. As discussed previously, the lower range of diversion rates (5% to 15%) are expected to be potentially achieved during initial operations after the Station expansion project is completed anticipated to be in 1995. It is unknown what exact diversion will be realized, however, this range is anticipated from the hand sorting proposed. This range can be increased to 25% initially if manpower and equipment are added. In the future, if mechanized equipment and additional labor is added, the diversion rates could be significantly higher. Appendix B contains a series of Tables III.C.3.a. titled for various anous hypothetical diversion percentages for the Station. The lowest is 5% and the highest is 50%. Under the 5% to 15% diversion range for the year 1995,6 to 19 trips are anticipated daily for removal of recyclable bins. If future diversion ranged as high as 50% of Station volumes, the number of trips per day would be approximately 87 in the year 2010 (assuming bins averaging 35 CY and 250 lbs/CY waste density). The estimated number of trips for Station waste stream diversion rates, under "high"Station waste projections, are shown on note number 4 on each of Tables III.C.3.a.,in Appendix B. It should be noted that these are preliminary estimates based on estimated Station waste quantities and assumed recovery percentages initially using limited hand and waste loader sorting on the tipping floor. Diversion could be increased by mechanization in the future or by increasing the number of sorters. The level of increase would depend on the type of system which could be chosen by the County in the future. The County proposes to use County drivers to deliver some of the recovered materials to off-site recycling facilities. Assuming that the average round trip to the recycling facility is 1-1/2 hours, 2 drivers could make roughly 10 trips per day. The County driver staff will be supplemented by off-site drivers from local recycling or recovery companies. Staging of bins for off-site removal is provided by 12 stalls in the Recycling Storage Area as shown on Drawing RSI-6. In addition, the Recycling Drop-off area has storage space available for contingency. (2) Removal of Non-recoverable Residuals The removal methods and frequencies for residuals is daily as described previously. Removal will be by transfer truck to a disposal facility.
