the annual operating cost budget for maintaining the number of trucks and trailers used during the pilot study period. A disposal fee reduction of $183,102 was recognized at WHSL due to the increased volume of solid waste at WSHL during the pilot study period. The fee was based upon 2012 tiered rates for solid waste disposal fees agreed upon between Waste Management, Inc. and the County of Hawaii. For the annual projected cost data in Table B, most of the values, except for fuel /oil, stayed constant with the data in the HLFS projections. The operating days and the average values for miles per trip, cost per gallon of fuel and the miles per gallon of fuel used differed from the assumptions in the HLFS report. Also, the disposal fee reduction during the HLFS reporting was based on 2011 tiered rates for solid waste disposal fees. DISCUSSION As a result of the effects of offsetting costs by the disposal fee reduction at WHSL, the net cost of long - hauling 4,155 tons of solid waste from East Hawaii to WHSL over the pilot study period of 75 days was $148,010 which yields a hauling cost $35.62/ton. Because this 4,155 tons of solid waste was not processed at the SHSL, it can be perceived that there was an avoided cost of $353,175 (based upon a landfill operating cost of $85 /ton for SHSL) resulting in a savings of $205,165, or $49.38/ton. Finally, it is noted that no complaints were received by DEM during the Pilot Study field test period. In the annual projected cost scenario, the assumptions in the HLFS report generally conform to the data collected during the Pilot Study field test. Although fuel and oil were significantly higher in the Pilot Study field test, there was an offset to the operating cost by greater disposal fee reductions at WHSL due to a greater volume price break. The estimated annual projected net cost for hauling all of East Hawaii solid waste to WHSL under the HLFS projection is $3.34M per year or $53.23 per ton; and under the Pilot Study projection is $3.28M per year or $51.71 per ton. The "average tons per load" in the Pilot Study data was significantly less than the value in the HLFS report. This would indicate that improvements to the compaction efforts and usage of particular types of trailers will be necessary to minimize the resulting number of trips taken and therefore the cost of hauling for a full -scale operation. The annual projected cost of long- hauling at full -scale is expected to range between $52 to $71 per ton, depending on individual component in loading and hauling, and whether a savings on volume price breaks are included. The East Hawaii Sort Station Traffic Study should be updated to properly assess additional impacts if long- hauling were pursued. As of this report, no final decision on a waste management alternative will be made without public input. 5
