2-3 2.3.1 Design Plans (14 CCR, Section 18221.6 (c)) The existing conditions plan, legal property limits, and topography are shown on Figure 2. A detailed site plan, including the unloading, compaction, processing, and loading areas, is shown on Figure 2. The RRF consists of one 12,000-square foot, 3-sided metal building. The floor plan and equipment layouts are shown on Figure 8. 2.3.2 Design Calculations (14 CCR, Section 18221.6 (g)) The RRF was designed in accordance with accepted engineering practices for this type of waste handling facility. Title 14 CCR regulations pertaining to the operation of transfer stations were developed to evaluate a facility's performance through objective periodic inspections. Design criteria utilized to determine the station's waste handling capacity, traffic loading and drainage system capability have been demonstrated repeatedly by the level of compliance the operator is able to maintain at the current permitted tonnage allowed in the SWFP. The maximum daily flow through capacity (i.e., the rate by which materials can be processed through the RRF) of the RRF was calculated to be 750+ tons per day (TPD). The storage capacity for the RRF building varies depending on the type of materials accepted. Based on the acceptance of recyclable materials, only the storage capacity is 200 tons up to a maximum 500 of tons based on the acceptance of heavier recyclables. The storage capacity calculations assumed that the largest manageable pile of material that will fit inside the RRF building, without impeding operations is 85 X 105 feet (which allows 15 feet of clearance around the inside perimeter of the building) and 12 feet high. Ropes are used to measure and limit the pile height (not to exceed 15 feet in height). The calculations are included in Appendix B. The assumptions used to calculate the volume handled at the site are as follows: ♦ The RRF operates 12 hours a day, 6 days a week. ♦ Transfer trailer loading rate of between 3 to 4 per hour(20-ton load). ♦ Unloading rate of 20+vehicles per hour. ♦ Based on RRF records,the average density of the wood is 330 Ib/cy. ♦ Based on published information,the average densities of cardboard, paper, and metal are 85, 150, and 270 Ib/cy, respectively. 2.4 Final Disposal (14 CCR, Section 18221.6 (m)) The final disposal of any residual wastes generated at the RRF are placed in a bin and disposed of at the Forward Landfill working face.
