To: M L Ref. Date AIIG 0 R in17 DEPARTMENT OF ENVIRONMENTAL MANAGEMENT LETTER REPORT: PILOT STUDY ON LONG- HAULING TO WEST HAWAII SANITARY LANDFILL July 25, 2012 Since 1992, various studies have recommended more than one alternative for the disposal of solid waste in Hawai'i County. Among the recommendations in the 2002 Updated Integrated Resources and Solid Waste Management Plan (IRSWMP), two of the recommendations stated "construct no new landfills in East Hawaii ", and "procure a waste reduction facility for the East Hawaii waste stream using either mass -burn waste -to- energy, thermal gasification, or anaerobic digestion technology ". Subsequent to adoption of the 2002 Updated IRSWMP, the County issued two (2) requests for proposals (RFP) for construction of a waste reduction facility. The first RFP issued in 2004 was cancelled by the County prior to award. The second RFP was issued in 2006 and later awarded to Wheelabrator Technologies for the construction of a mass -burn waste -to- energy facility at the County -owned South Hilo Sanitary Landfill (SHSL). In 2008, due to higher than anticipated construction and operation costs, the County Council rejected the second RFP. The 2009 Updated IRSWMP made residual management strategy recommendations including evaluating the feasibility and cost - effectiveness of developing a new lined landfill adjacent to the SHSL site and long- hauling solid waste to the West Hawaii Sanitary Landfill (WHSL) site taking into account hauling operations, haul routes, traffic issues and equipment acquisition plans. In 2011, the Department of Environmental Management executed a contract with R.W. Beck to perform this evaluation and provide a report. The Hilo Landfill Feasibility Study (HLFS) report was finalized in March 28, 2012 which evaluated the technical, economic, environmental, socioeconomic and regulatory /permitting feasibility of landfilling adjacent to the SHSL. R.W. Beck updated and refined the planning level cost estimates presented in the 2009 Updated IRSWMP for landfilling and long- hauling from SHSL to WHSL. As summarized in R.W. Beck's report, the resulting net cost for landfilling ranged from $70 /ton to $130 /ton (excluded were financing costs) depending upon the method of leachate treatment. The resulting net cost for long- hauling ranged from $53 /ton to $57 /ton depending on variations in individual cost components of loading and hauling. This also included the estimated savings derived from a lower disposal rate for landfilling the east side tonnage at WHSL. If the cost savings for landfilling at WHSL are excluded, the net cost for long- hauling would range from $67 /ton to $ 71 /to n. R.W. Beck's opinion was that while technically feasible, permitting and land use constraints, and leachate management issues made design and permitting of a landfill expansion impractical and uneconomical. Moreover, based on the updated and refined planning level cost estimates, long- hauling from SHSL to WHSL was a potentially feasible and more cost - effective disposal alternative. The report's final recommendation was to update the February 2004 traffic impact assessment prepared for the Final Environmental Impact Statement for the East Hawaii Regional Sort Station. 1 In January of 2012, the Department of Environmental Management, Solid Waste Division conducted a long -haul pilot study between East Hawaii and the WHSL which is operated by Waste Management, Inc., under contract with the County of Hawaii. The purpose of the study was to field test the hauling assumptions and verify the planning -level cost estimates presented in the HLFS report. The intent was to collect a sufficient amount of data on a short -term basis and it was determined that 3 months was an adequate amount of time to field test the hauling assumptions. The purpose of the long -haul pilot study was to: 1. Field test the hauling assumptions made in the HLFS report by obtaining the following field data and comparing it to data in the HFLS report: • Fuel consumption • Fuel cost • Travel time • Travel distance • Travel route • Tonnage per trip • Trips per day 2. Determine effect of additional solid waste volumes from East Hawaii on disposal fees at WHSL (see note below on disposal fees). 3. Derive an estimated annual cost of hauling WHSL using pilot study projections. 4. Evaluate the impact of long- hauling on traffic and the environment. Note: Unlike the SHSL which is operated by the County of Hawaii, Waste Management, Inc. (WMI) is contracted with the County of Hawaii to operate the WHSL. WMI receives payment for their services by charging the County a per ton disposal fee at a rate that is based upon the average daily incoming tonnage for that whole month. It is on a sliding scale such that the more the tonnage, the less the disposal fee charged to the County. 3RnCEC The long -haul pilot study was initiated on January 27, 2012, and was conducted six (6) days a week through April 28, 2012. Each day, a total of four (4) SWD equipment operators were assigned as truck drivers at the Hilo baseyard. One equipment operator on light duty maintained data and two (2) SWD supervisors scheduled the drivers' daily assignments. Workers drove between the hours of 6:30 am and 5:00 pm. Refuse collection trailers from the transfer stations located south of the Hilo baseyard — Volcano, Glenwood, Kalapana, Pahoa and Kea'au — were hauled to the Hilo baseyard where they were parked overnight and hauled to the WHSL at Pu'uanahulu the next day. Refuse collection trailers from the two 2 (2) transfer stations located north of the Hilo baseyard — Papa'ikou and Honomu — were hauled directly from the transfer stations to the WHSL. One round trip constitutes a single load being transferred to WHSL. Depending upon driver availability and the amount of refuse to be hauled to WHSL on a given day, each driver completed up to two (2) round trips daily resulting in a daily average of four (4) round trips between the total number of drivers. Overall, round trips per day varied between one (1) and (9). Average road time for each driver was four (4) hours per round trip. Drivers hauling refuse collection trailers to WHSL were responsible for emptying, cleaning and hauling the trailer back to the Hilo baseyard, or to Papa'ikou and Honomu transfer stations on the same day. A total of 24 trailers with 70 and 100 cubic yard (c.y.) capacities were used in the pilot project. The 100 - c.y. trailers which do not have built -in compactor units are only at the Pahoa transfer station site. All 70- c.y. trailers are equipped with built -in compactors. All trips were made along the Hamakua Coast (see Figure 1). This route was considered to be the safer route for long- hauling until upgrades to the Saddle Road portion closest to Kona can be completed. FIGURE 1: Pu' HAULING ROUTE FOR PILOT STUDY Performance Data: During the pilot study period, drivers made a total of 303 trips over 75 days and hauled a total of 4,155 tons of solid waste from east side to WHSL. Table 1 shows a comparison of average data between the HLFS assumption values and the field -based values derived during the 3 -month pilot study. Table A in the Appendix A shows additional field -based values with details recorded during the course of the pilot study. The road time value is the sum of each driver's time (averaging four (4) drivers per day) spent on the road traveling to and from WHSL. A total of 14,261 gallons of fuel was expended during the pilot study for a total fuel cost of $59,277, at an average per gallon cost of $4.16. TABLE 1: Average Data Comparisons LOGISTICS HLFS Data Pilot Study Data Fuel — Miles Per Gallon 4.5 3.67 Round Trip Time 4 hours, 36 minutes 4 hours, 12 minutes Miles Per Trip 156 172.5 Fuel Cost Per Gallon $3.10 $4.16 Tons Per Day, East HI 205 (64,000 =312 days) 55 (4,155 =75 days) Tons Per Day, West HI 280 275 Tons Per Trip 20 13.71 Trips Per Day 10 4 Estimated Pilot Study Cost & Annual Projected Cost Data: A line item of costs are shown in Tables A and B within Appendix B. The labor cost including fringe benefits is comprised of regular and overtime costs of $9,587 and $37,676. The fuel /oil cost of $59,277 is from Table A within Appendix A. The maintenance /tires cost of $10,008 is a percentage estimate of 4 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 TABLE A APPENDIX A PILOT STUDY FIELD DATA SUMMARY Road Time hour:min Fuel Mileage MPG Trips Avg miles /trip Cost /gal Total Fuel Cost Days Hauled Avg Trips per Day Total Tons per Mon Avg Tons Per Day Avg Tons per Trip Jan 38:54 427.00 1,552.90 3.6367681 9 172.54 3.86 1,648.22 4.00 2.25 104.85 26.21 11.65 Feb 297:54 3,391.90 11,994.00 3.5360712 69 173.83 4.00 13,567.60 22.00 3.1363636 887.71 40.35 12.87 Mar 472:16 5,319.20 19,273.20 3.6233268 113 170.56 4.20 22,340.64 26.00 4.3461538 1,549.59 59.60 13.71 Apr 463:47 5,122.70 19,457.30 3.7982509 112 173.73 4.24 21,720.25 23.00 4.8695652 1,613.08 70.13 14.40 Totals 1272:51 14,260.80 52,277.40 3.6658112 303 172.53 4.16 $59,276.71 75.00 4.04 4,155.23 55.40 13.71 APPENDIX B TABLE ESTIMATED PILOT STUDY COST Labor: Fuel /Oil: Maintenance /Tires: WHSL Tipping Fees: TOTAL COST: Less Fee Reduction at WHSL: NET COST: Less Avoided Cost at SHSL: SAVINGS (75 days): $ 47,263 (includes fringe benefits) $ 59,277 $ 10,008 $214,564 (4,155 tons x $51.64/ton) $331,112 -$183,102 (21,217 ton/ x *- $8.63 /ton) $148,010 (4,155 tons = $35.62/ton) - $353,175 (4,155 tons x * * -$85 /ton) - $205,165 (4,155 tons = - $49.38/ton) 9 *$51.63 - $60.27 = -$8.63 * *Estimated cost /ton to run SHSL APPENDIX TABLE B ESTIMATED ANNUAL PROJECTED COST OF LONG-HAULING _Ammal Projected C'ost: llLFS Projections Pilot Studv Projections 10 S 606,147(5':14750ri-ii 10 Insurance, License.

Objectives: 1. Provide background. 2. Evaluate 3 alternatives: • Waste -to- Energy • New Hilo Landfill • Hauling to West Hawaii Sanitary Landfill (WHSL) 3. Discuss purposes and results of Hauling Pilot Study. 07/02/12 BACKGROUND 1. Since 1992 - Various studies have recommended more than one alternative for the disposal of solid waste in Hawaii County. 2. 2002 — Integrated Resources and Solid Waste Management Plan (IRSWMP) recommended that County pursue waste-to- energy (WTEJ proposal. RFP issued in 2007. 3. 2008 — WTE proposal rejected by Council as being too costly. 4. 2009 — For long -term solid waste management for East Hawaii, updated IRSWMP recommended the evaluation of hauling rubbish to WHSL and building a lined landfill in Hilo. 5. 2011 — DEM executed contract with R.W. Beck to perform this evaluation. 07/02/12 BACKGROUND (cont.) 6. 2012 — Hilo Landfill Feasibility Study (HLFS) compared costs of building and operating a new landfill in Hilo with hauling waste to the WHSL. The HLFS concluded that hauling is the more cost - effective alternative. 7. 2012 — DEM conducted a pilot study to field -test the hauling assumptions made in the HLFS. 8. 2012 — DEM determined that all of Hawaii County's annual rubbish totals to 63,446 tons in East Hawaii (205 tons / day ; and 103,009 tons in West Hawai 'i 332 tons /day based on FY 2010 -11 information. The average total daily tonnage for East and West Hawaii is 537 tons / day. 9. 2012 — The County's island -wide estimate to collect, haul, and dispose of rubbish is $137 per ton. 07/02/12 WASTE -TO- ENERGY (RFP) A Waste -to- energy RFP was issued in 2007 for the management of East Hawaii's solid waste. The winning proposal was rejected by the Council in 2008 as being too costly.

J�1J�������I Results: i. The assumptions in the HLFS generally conform to the data from actual field operations of the Pilot Study. 2. Although fuel and oil were significantly higher in the Pilot Study, it was offset by greater disposal fee reductions at WHSL due to the volume price break. Combining the waste from East Hawai' i and West Hawai' i amounted to approximately the same cost per ton in both studies. I The annual projected cost in the HLFS is $3.343 million, or $52.23/ton. The annual projected cost in the Pilot Study is $3.281 million, or $51.71 ton. a. There were no significant increase in equipment maintenance. 5. No complaints were received by the DEM during the Pilot Study. 07/02/12 L-1-1 HAULING (Hauling Pilot Study cont.) Conclusions: 1. The actual tons per load in the Pilot Study was significantly less than the HLFS Study. This means that improvements in compaction and types of trailers used will be necessary to minimize trips taken and cost of hauling. 2. The East Hawai' i Sort Station Traffic Study should be updated to assess additional impacts if hauling is pursued. 3. Projected cost of hauling to the WHSL is between $52 /ton and $71 /ton, depending on whether savings on volume price breaks are included. 4. Although hauling to the WHSL is the least costly of the three alternatives discussed, no decision will be made without public input. 07/02/12 Annual Cost -Range Comparisons ® lJll�l�JIJ��I) J��J�lllJJ�J1J�J1J JJJJJ�J�JJJ�1JJlJJJ�JJ�J�J��1J1�1�1 J�J�JJ�JJllll�lJ�IJJ�IIJ��IJJ�IJ�JJJJJJJJJ�JJ1JJJJJJ1J�1 J�J1 J1�1J111J�JI Solid Waste Alternatives $200 /ton $150 /ton $100 /ton $50 /ton _Lnergy Landfill Hauling
