Comprehensive Review of S olid W aste Collection and Disposal Options v2.1 86 10/22/12 reported in units of cost and summarized for the current month, 12-month rolling total, and vehicle life-to-date. In addition vehicle mileage is tracked and recorded in the same manner. Using these actual data, the historical and projected fleet operational cost was computed on a per mile basis and allocated accordingly by vehicle to residential and commercial sector operations. As previously discussed in Section 2, Exhibit 6-4 summarizes these projected vehicle operations costs. The scenario modeling analysis includes these costs as new vehicles are added to the fleet in the projections according to their respective use (i.e., residential or commercial), which are adjusted in accordance with inflation assumptions. Exhibit 6 -4. Projected Town Vehicle O&M Cost Vehicle Description Maintenance & Repair Cost ($$ per mile) Total Cost Including Fuel ($$ per mile) Commercial Front Loader 1.43 2.35 Residential Rear Loader 1.38 2.28 Hooklift 1.45 1.74 Knuckleboom 0.91 1.60 Scooter Truck 0.37 0.66 Flat Bed 0.22 0.58 Pick-up/Passenger Car 0.08 0.23 The analysis assumes a cost of diesel fuel of $2.91 per gallon based on information provided by the Town. This cost is the tax-exempt purchase price of fuel provided by the Town at the PW garage facility. 6.3.3 Impacts to Task -Based Collections System Structure As described above, this analysis concludes that routing modifications are necessary to accommodate the projected waste disposal volume, corresponding NCDOT weight limits, and additional transit and queuing time required to transport and dispose of waste at an existing transfer station. A review of current collections schedules (7 residential routes 4 days per week, 2 commercial routes 5 days per week) and compensation structure indicates:  The average residential collection route (i.e., task) requires approximately 6 working hours per day. The collections staff is typically free to leave each day upon the completion of their task. Residential collections staff are currently compensated for four (4) 10-hour days (i.e., 40-hours) per week with Wednesdays off.  The average commercial collection route requires 5 working hours per day. Similarly, the collections staff is typically free to leave each day upon the completion of their task. The commercial collections staff is compensated for five (5) 8-hour days (i.e., 40 hours) per week. Using the distance to each target transfer station and assuming average highway speeds consistent with these distances, the off-route (i.e., transport and tip) time associated with each transfer station location was estimated. For comparison, SCS calculated available off-route time
