Total annual residential MSW disposal = 6,725 tons. <br />2. SWANA resources support typical industry compaction density of in-truck waste ranges between 500 <br />and 1,000 pounds per cy. <br />3. Each route anticipated to include one 19 cubic yard rear loader compaction vehicle making one trip <br />per collection day. <br />Adjusting the number of collection days or routes, is necessary to adequately distribute the daily <br />collection volume among the subject vehicles, thus enabling each collection route to make a <br />single trip to the transfer station during each collection day, while also mitigating the potential of <br />the residential collection vehicles exceeding their legal weight limit during the periodic use of <br />the single-axle trucks comprising the reserve fleet. This analysis highlights that understanding <br />the Town’s actual waste compaction density is critical to configuring the route distribution. <br />This analysis assumes that as the existing cubic yard single-axle fleet reaches the end of its <br />operating life (deemed to be 7 years), these vehicles will be replaced with new 18 to 20 cubic <br />tandem-axle vehicles and the older tandem-axle vehicles will become a backup piece of <br />equipment in the reserve fleet. Certainly the replacement vehicles purchased in the future could <br />be larger capacity, such as 25 cubic yards. Accordingly, these tandem-axle vehicles will further <br />enable the Town to meet its load capacity and NCDOT weight limits. <br />Furthermore, the analysis includes a separate scenario which evaluates phasing in automated <br />collection vehicles targeting appropriate areas of the Town which can accommodate automated <br />collection services. Refer to Section 4 for further discussion regarding introduction of automated <br />collections. <br />For this short-term, direct haul option, additional routing and scheduling modifications to the <br />commercial fleet are anticipated to accommodate the legal weight limits and multiple direct haul <br />trips to a transfer station. This analysis anticipates that implementing the commercial collections <br />recommendations, including a routing study, identified in Section 4 will promote collection <br />efficiencies that would likely allow the commercial collections vehicles to continue to make two <br />(2) daily trips to the target transfer station while evenly distributing the waste into highway legal <br />loads. <br />6.3.2 Fleet Fuel and Maintenance Costs <br />All Town collections vehicles are garaged, serviced, maintained, and fueled at the Public Works <br />facility. The vehicles dispatch from and return to this same location after each collection route. <br />The Town maintains a detailed maintenance, repair, and fuel consumption log for each vehicle
