Olver staff conducted <br />additional drive tests and confirmed that the mileage and speed data provided by the Towns and the <br />County used to estimate off-route hauling costs are in-fact accurate. No changes have been made to <br />the distance and speed assumptions between collection routes and transfer station options. Speed <br />and distance assumptions from the proposed County transfer station locations to the out of county <br />landfills were also revaluated. In order to standardize the long haul routing approach Olver has <br />selected Interstate routes even if there are shorter routes to the destination landfill. This approach <br />has resulted in changes to mileage assumptions and cost estimates for long-hauling MSW that have <br />had more impact on routing to Wake County Landfill than to Sampson County Landfill. <br />Table 3A presents the data that incorporates the new mileage assumptions. The costs to haul MSW <br />to the Sampson County Landfill from the Eubanks Reference facility and the Highway 54 site were <br />virtually unchanged and increased 2.7% respectively. Hauling to the Wake County Landfill from <br />the Eubanks Reference facility and from the Highway 54 site increased 4.3% and 5.8% respectively. <br />Table 3A also presents revised data as a result of the additional residential collection routes <br />requested by Chapel Hill. However, these revisions do not impact the overall findings or the <br />Z~ IProjectslOmnge Covnty1101 SlITRANSFER STUNG PROJEC7IDOCSI2009_06-02 -Gayle Rr/son - TSHav/Cost Analyses Revised - Chape/ Hi[Ldoc <br />cSarvujy'ifirgetrisend Au Grdimaat far anu 3(1 Ilt~ <br />$724 Red Oak Beelerard, Suite 545 eaa.~ {744) 524--3.127 <br />t'karbtte,NC 28217 e~ (744j 527-322$ <br />www.alraces <br />
