Facility Capacity Study <br /> Tracy Material Recovery Facility and Transfer Station Expansion <br /> 30703 S. MacArthur Drive, Tracy, California 95377 <br /> Traffic Handling Analysis <br /> Vehicles delivering and removing materials from the Tracy MRF & TS include (1) Tracy <br /> Delta Solid Waste Management (TDSWM) collection trucks, including front-end loaders, <br /> rear-loaders, and debris box/roll-off hauling vehicles, (2) self-haul vehicles (mainly pick- <br /> up trucks and passenger-vehicle-drawn, small- and medium-size trailers), (3) trucks <br /> removing recovered materials, (4) and transfer trucks carrying solid waste to a landfill <br /> from the transfer facility. The calculations for potential vehicle throughput for each <br /> operational area are shown in Table 7 below. <br /> Table 7 <br /> Project Traffic Capacity Analysis <br /> Vehicle Classification/ Load/Unload <br /> Operational Area Number Time Vehicles per loading Total Vehicles/ Peak <br /> Of Spaces (avg.minutes) space/hour Hour Hour <br /> A Per Vehicle (60 min../B=C) (A x C=D) 10am to 11 am <br /> B <br /> D <br /> Inbound <br /> Material Recovery Facility and Transfer Station operations area—See Figure Al for number of spaces <br /> Commercial MSW 9 6 10 90 27 <br /> Self—Haul MSW 16 10 6 96 25 <br /> Commingled <br /> Recyclables 4 6 10 40 12 <br /> Source-Separated <br /> Recyclables 10 6 10 100 10 <br /> C&D Processing Area operations —See Figure A2 for number of spaces <br /> Self-Haul C&D 13 10 6 78 32 <br /> Commercial C&D 7 1 6 1 10 70 8 <br /> Compost Processing Area operations —See Figure A3 for number of spaces <br /> Self-Haul Compost 13 10 6 78 14 <br /> Commercial Compost 7 6 10 70 16 <br /> Inert Processing Area2 20 3 6 5 <br /> Total Inbound Peak Traffic 149 <br /> Outbound <br /> MSW Transfer 2 5 12 24 10 <br /> Recyclables Transfer 3 20 3 9 5 <br /> Compost Transfer 2 10 6 12 3 <br /> C&D Wood Transfer 3 1 10 6 18 4 <br /> Total Outbound Peak Traffic 22 <br /> Proposed scalehouse traffic can be handled with the use of two inbound scales for self- <br /> haul vehicles and one scale for commercial vehicles. On site survey data reveals that <br /> the average processing time necessary at the scalehouse is 10 seconds for each <br /> TDSWM commercial vehicle and approximately 45 seconds for each self-haul vehicle. <br /> Peak incoming hourly traffic at the proposed 2,500 TPD capacity is 149 vehicles (59 <br /> commercial and 90 self-haul vehicles). With two scales handling incoming self-haul <br /> vehicles, over 120 self-haul could be processed each hour; one scale could handle in <br /> s <br />
