Comprehensive Review of S olid W aste Collection and Disposal Options v2.1 140 10/22/12 10.2 SCENARIO MODELING AN ALYSIS Like the short-term disposal option of direct hauling to a transfer station, the scenario modeling analyses of this short-term disposal option were structured to result in the least impact to the current level of service that Town customers receive and the least disruption to existing Town collections systems, personnel and equipment; while also providing sufficient collection capacity to enable Town vehicles to make a single trip to the target landfill per day. Furthermore, the various scenarios within this analysis include program modifications that are anticipated to reflect changes in equipment, personnel, and routing over time (e.g., scheduled fleet replacement, inflation, and population growth, etc.). For this MSW disposal option of direct hauling to an existing transfer station, the analysis incorporates the allocated equipment and labor waste collections resources provided in the Town‘s FY 2012-13 budget. The routing configurations, labor, and equipment are allocated such that each residential collections crew can collect along its dedicated route, transport, and generally dispose one (1) load at the Orange County Landfill within the workday. This analysis recognized that a few Town vehicles make a second trip along a limited number of routes. The commercial collections crew usually accomplishes disposal of two loads at the Landfill per day. The evaluation of the direct haul scenarios is structured to enable the residential and commercial crews to avoid having to complete multiple trips to the target landfills. Other relevant assumptions critical to this direct haul to a landfill analysis are identical to those made with SCS’s evaluation of direct hauling MSW to a target transfer station facility. Detailed discussions of these assumptions are presented in Section 6 and include:  Collections Fleet Modifications and Capital Expenditures - Compliance with NCDOT Overweight Regulations - Systematic Replacement of Single-axle vehicles with Tandem-axle vehicles - Assumed the Town’s budgeted annual capital expense for previous equipment replacement as provided = $311,000 per year  Existing Fleet Summary and Projected Replacement Schedule - Seven (7) Residential routes - Two (2) Commercial routes - Seven (7) year vehicle replacement schedule initiating with existing vehicle age  Fleet Modifications - Scheduled replacement of existing Residential rear loader vehicles with tandem-axle 18 to 20 cubic yard vehicles according to the 7-year schedule. Larger capacity vehicles (25 cubic yard) can be utilized as well. Next scheduled replacement FY 2012-13. - Annual amortization cost according to a 7-year amortization schedule and 4% financing rate - No modifications to Commercial collections fleet  Routing Modifications - Evaluated adding one (1) additional Residential route, resulting in a total of seven (7) routes. Equipped with an existing, stand-by collection vehicle. - One (1) additional 3-man crew for this seventh route
