<br /> Comprehensive Review of <br /> S olid W aste Collection and Disposal Options <br /> <br />v2.1 107 10/22/12 <br />County Landfill. The commercial collections crew usually accomplishes disposal of two loads at <br />the Landfill per day. The evaluation of the new transfer station scenarios is structured to enable <br />the residential and commercial crews to complete the same number of trips to a hypothetical new <br />transfer station as they currently perform to the Orange County Landfill. <br />Relevant assumptions critical to this new transfer station disposal scenario analysis are <br />summarized below. More detailed discussions of these assumptions are presented previously in <br />Section 6, direct hauling MSW to a target transfer station facility. <br /> Collections Fleet Modifications and Capital Expenditures <br />- Consider compliance with NCDOT Overweight Regulations a non-issue <br />- Systematic Replacement of Single-axle vehicles with Tandem-axle vehicles <br />- Assumed the Town’s 2013 budgeted annual capital expense for previously <br />purchased equipment as provided = $311,000 per year <br /> Existing Fleet Summary and Projected Replacement Schedule <br />- Seven (7) Residential routes running 2 days per week <br />- Two (2) Commercial routes <br />- Seven (7) year vehicle replacement schedule initiating with existing vehicle age <br /> Fleet Modifications <br />- No additional Residential rear loader collection vehicle is necessary <br />- Annual amortization cost according to a 7-year amortization schedule and 4% <br />financing rate <br />- No modifications to Commercial collections fleet <br /> Routing Modifications <br />- No additional Residential route is necessary; seven Residential routes running 2 <br />days per week <br />- No additional 3-man crew for residential route <br />- Analysis excluded consideration of automated collections route <br /> Fleet Fuel and Maintenance Costs <br />- Determined from historical Town records <br />- Incremental savings resulting from traveling shorter distance to new transfer <br />station <br />- Includes incremental costs for replacement vehicle(s) on a year-over-year basis <br /> Impacts to Task-Based Collections System Structure <br />- No modification of existing off-route time to transport MSW to new transfer <br />station <br />- Maintain available flex time currently awarded to collections staff <br /> Other Assumptions <br />- Each modeling scenario includes the forfeiture of current transportation and <br />disposal costs associated with hauling to the Orange County Landfill but accounts <br />for the transportation and disposal costs associated with hauling waste in transfer <br />trailers to target destination landfill on facility-by-facility basis <br />- 3% cost of inflation <br />- Baseline fiscal year of FY 2012-13 for comparison purposes <br /> <br />
