Solid Waste Operations Center Design The architectural firm of Dixon Weinstein will provide the Board of Commissioners with a presentation on the proposed design of the new Solid Waste Operations Center to be located on the south side of Eubanks Road, immediately adjacent and to the west of the County's mixed solid waste (MSW) landfill. The Solid Waste Advisory Board (SWAB) received a brief presentation from the architects at their March 2 meeting and gave a favorable review to the planning efforts to date. After receiving the Board's direction on facility design elements, staff and the architects will make appropriate revisions and schedule a meeting with community representatives to review with them the BOCC's proposed design for the facility. The project timeline at this point contemplates soliciting and awarding construction bids in late summer or early fall, with move in to the new facility targeted for mid -2007. No Attachments B. SWAB Recommendation Regarding Transfer Station Siting At the November 9, 2005 work session on solid waste matters, the BOCC instructed staff to conduct analysis and proceed with developing recommendations regarding the siting of a transfer station in Orange County. The County's MSW landfill is expected to reach capacity sometime in 2010 and, in light of the policy decision not to site any new MSW landfills in Orange County in the future, a transfer station will be needed as a staging point for the shipment of waste to disposal facilities in other jurisdictions. The SWAB has reviewed the analytical work performed by staff and the County's consulting engineering firm (Olver Incorporated) and has adopted the attached resolution recommending that the BOCC direct staff to proceed expeditiously with permitting, design, and construction of an MSW transfer station.

Solid Waste Convenience Center Siting Issues The County received notice in August 2005 from the new owner of property on which the Highway 57 SWCC is located that the County's lease would not be renewed upon its expiration on April 1, 2006. Staff then began working to examine alternatives to that site that would allow the County to continue providing service to residents who use that site. The property owner and BOCC approved an agreement in February 2006 that provides for the Highway 57 site lease to extend automatically for two -month periods, subject to 60 days notice by either party to terminate the arrangement. While this lease extension provides some latitude, staff are vigorously pursuing both long -term and short-term options for continuing convenience center services after the Highway 57 site closes. Staff will report on efforts to date to examine potential property acquisitions that could lead to co- located County facilities, such as a park and convenience center. As was discussed at the joint work session with the Hillsborough Board of Commissioners on February 23, staff will also review with the Board options for a possible temporary convenience center site at the County's Public Works facility on Highway 86. No Attachments D. Greene Tract Disposition In June 2002, the Greene Tract Work Group adopted the attached resolution recommending to the County and Towns of Carrboro and Chapel Hill that approximately 86 acres of the Greene Tract be preserved as open space protected by conservation easements and that approximately 18 acres be earmarked for affordable housing purposes. This portion of the work session provides the Board with an opportunity to discuss and provide direction to staff on how to proceed with either or both components of the Greene Tract disposition.

Interim Report from SWAB Work Group on Solid Waste Management Plan Update The next three -year update of the County's 10 -year solid waste management plan is due to the State of North Carolina in Summer 2006. County staff have been working with the SWAB and elected officials from each Orange County local government to examine the County's current goals and solid waste plan, and to develop proposed recommendations for consideration by the various governing boards related to the goals and the best array of programs and services for achieving those goals. The accompanying report, prepared by the Solid Waste Management Director and staff, and reviewed by the SWAB Chair, provides an update for all four governing boards regarding progress to date. Attachment E 3115106 Solid Waste Management Director Memo — Interim Report 3 F. Feasibility of Landfill Gas Recovery The BOCC asked staff to examine the feasibility and implications of recovering gas from the County's MSW landfill and converting it to energy that could conceivably be used to provide power to various County or other public facilities. The accompanying report from the County's consulting engineers discusses the potential for landfill gas recovery, and some of the implications, benefits, and costs that might be associated with such an undertaking. This report is provided simply for information at this time, although staff will receive Commissioner comments and questions and perform further coordination with the consulting engineers as necessary and appropriate. Attachment F March 2006 Landfill Gas Recovery Feasibility Study FINANCIAL IMPACT: There is no financial impact at this time associated with discussion of these topics. The Board's decisions in the future to develop additional needed solid waste management facilities would be funded through future appropriations in the Solid Waste /Landfill enterprise fund. Depending on the timing of conservation easements and affordable housing development on the Greene Tract, the County and Towns will be responsible for reimbursing the enterprise fund for the original purchase cost of the property, plus interest, in keeping with the interlocal agreement governing solid waste matters. RECOMMENDATION(S): The Manager recommends that the Board discuss the solid waste topics mentioned above and provide appropriate direction to the Manager and staff. Memorandum To: Mr. Barry,Jacobs, Chair Board of County Commissioners, Orange County CC: Mayor Foy, Chapel Hill Mayor Stevens, Hillsborough Mayor Chilton, Carrboro From: Dr. .Jan F. Sassaman, Chair Orange County Solid Waste Advisory Board Subject: Resolution to Recommend the Landfill Property Located North of Eubanks Road as the Future Site of the Orange County Transfer Station Date: March 2, 2006 In response to the request of the Board of County Commissioners, the Solid Waste Advisory Board (SWAB) has considered options for location of the future Waste Transfer Station on landfill property located north of Eubanks Road provided by Olver Incorporated, consultants to the Solid Waste Management Department. The present landfill property identified by Olver is physically amenable as a location of the transfer station, and is also ideally situated from an operational standpoint in terns of local land use, transportation issues of proximity to sources of waste and to Interstate roadways, and existing use of the property. Therefore, the attached resolution recommends, as a result of a unanimous vote of the SWAB, that the landfill property located north of Eubanks Road be used as the future site of the Orange County Transfer Station. Furthermore, since the Board of County Commissioners has affinned that there will be no future county -owned municipal solid waste landfill in the Orange County, the SWAB recommends that the Board of County Commissioners proceed expeditiously to design, permit and construct the Transfer Station so as to maximize retention of existing MSW landfill capacity for a disposal contingency. Please let me know if you have any further questions.

and WHEREAS, title to 60 acres of this property was deeded exclusively to Orange County in 2000 under provisions of the 1999 interlocal "Agreement for Solid Waste Management'; and WHEREAS, under the same interlocal agreement the County and Towns agreed to bargain in good faith during the two year period following the effective date of the agreement to determine the ultimate use or disposition of the balance of the acreage on the Greene Tract; and WHEREAS, the end date of the "bargaining period" as defined in the agreement was April 17, 2002, the second anniversary of the date upon which the County assumed overall responsibility for solid waste management in Orange County; and WHEREAS, the Greene Tract Work Group considered direction from the respective governing boards, comments from interested citizens and organizations, and information developed by staff in response to Work Group inquiries in developing a recommended concept plan for the balance of the Greene Tract; and WHEREAS, the Work Group reported to all three governing boards in a resolution dated March 21, 2002 that it had reached substantial agreement on a concept plan providing for approximately 78 acres to be earmarked for open space protected by conservation easements and approximately 15 acres to be earmarked for affordable housing but had not yet reached agreement regarding what designation should be placed on the remaining 11 acres; and WHEREAS, the Work Group had recommended in that March 21, 2002 resolution that the following additional steps be taken: • The area shown on the concept plan as open space should be protected by executing a conservation easement between appropriate parties • The Board of County Commissioners should consider protecting its 60 acre portion of the Greene Tract by executing a conservation easement with an appropriate party • The Chapel Hill Town Council should consider initiating a small area planning process to examine desirable land uses for the Purefoy Road area • The property should be renamed in a manner that recognizes the significance of this area as the headwaters for three important streams (Bolin Creek, Old Field Creek, and Booker Creek) • The governing boards should take note of the public investment already made in the general vicinity of the Greene Tract, as cataloged in an accompanying table; and WHEREAS, the governing boards of all three jurisdictions approved resolutions extending the bargaining period beyond April 17, 2002 in order to allow the Greene Tract Work Group additional time to try to reach consensus on the basic uses to be established for the approximately 11 acres at that time unresolved;

Cal Horton, .John Link, Eric Peterson, Steve Stewart, Jan Sassaman Attachments: .3 This memorandum provides an update of the work and meetings of the Solid Waste Plan Work Group from its inception in April 2005 to date. The memo also reviews the information presented to the Work Group and presents a projected schedule and tasks for work yet to be completed. Background Last February, the Board of Orange County Commissioners tasked the Solid Waste Advisory Board (SWAB) with moving the solid waste planning process forward to develop the next three year update required by the State of North Carolina and also to clarify and create consensus on that plan as a road map for long teen solid waste planning in Orange County. The SWAB's response was to expand into a broader working group for this task. Dubbed the Solid Waste Plan Work Group, it includes the current SWAB membership and Solid Waste Department staff, an elected official and key staff people from each jurisdiction, as well as an additional staff person from UNC. (List of'work group membership Attachment 1). A subsequent staff memo (Attachment 2) introduced a possible schedule through which the Board could receive an updated solid waste plan for submittal to the State by the statutory due date of June 30, 2006 It has become clear due to our rate of progress on this project, as well as the upcoming budget work required by the various elected Boards and their staff, drive a realistic date of completion later into calendar 2006. It is reasonable to say that the three -year, update of the ten -year plan will not occur by June 30, 2006. That delay will allow a more thorough consideration of all the elements of a relatively complex plan by all the jurisdictions and should result in an effective consensus on a plan that moves deliberately towards the County's stated 61 % waste reduction goal. Summary of Meetings The work group began meeting in April 2005 and has met six times: April .June October May September November A brief'recap of the primary discussion topics of each meeting is below. The minutes from the meetings are available on request from the Solid Waste Management Department. April: Introductory meeting with a brief history of solid waste management in Orange County and opportunity for each jurisdiction to state its concerns about solid waste. This meeting was essentially an open forum for discussion of topics of interest by each member. Topics included: • Meeting the 61 % goal • Transitioning from landfill to transfer station. • Handling commercial waste. • Allocating recycling fee fiords among programs. • Residential OCC collection. • Expansion into commercial recycling • Effects of PAYT on dumpster systems • Ability to process commingled materials locally. • Future tipping fees. • How to achieve higher recycling rates. • hrtegration of recycling with other aspects of solid waste management. • Limits of recycling. • Need for disposal options. • Financing. • Private sector compliance with County (and Town) regulations, May Presentation on how the waste reduction rate is calculated, showing it at 46% for 2003- 04, how C &D waste has been reduced and the potential within the waste stream to get to 61% reduction from the current 46 %. Continued discussion of the underlying issues included: Solid Waste Fund solvency. Expanding the number of materials collected, particularly mixed paper and a PAYT system. The need to build a large MRF that is dependent on huge amounts of material versus tailoring a processing facility to meet only estimated local processing requirements. June Report on waste stream analysis, comparing 2000 to 2005. Discussion of keeping the goal if it is hard to reach given the current materials discarded. Additional discussion consisted of PAYT and the Work Group and /or SWAB role in it. Focus future discussions on collection and processing (of recyclables). Collection of recyclables at the curb in carts v. bins. September Report on collecting additional materials including residential food waste, other (non -food) organics, plastic film, injection molded plastics, scrap metal, textiles, electronics, clean wood. These show that at a 50% capture rate for all recyclables remaining in the waste that Orange County could reach 54% a waste reduction rate. Disposal options were discussed and recycling collection options were tabled. Report on administrative cost of PAYT was submitted with no presentation. October Report on residential recycling options dual- stream v, single- stream /automated v, semi - automated. Report on commercial recycling options delivered but not presented orally, Commercial recycling waste stream analysis and options presented. November Clarification of commercial waste analysis, PAYT cost presentation, landfill v. transfer station, and solid waste collection in Orange County. Other informational staff reports have also been prepared but not presented addressing drop -off sites and rural waste collection. At the November meeting, the Work Group realized they had been presented with a significant amount of information and had given staff and SWAB some feedback and direction. They stated their ° next step would be to have staff prepare some analyses of possible program options. Through December, January and February, the SWAB continued to receive informational reports about aspects of the current system including rural garbage collection, multifamily recycling, regulatory mechanisms for increasing recycling and controlling waste, transfer station development, development of MRF and landfill siting guidelines. The remaining Work Group members can readily review these presentations and the minutes of the subsequent discussions to further their decision - making effectiveness. The initially planned trajectory was for the Work Group to reconvene once the recycling programs' technical analysis had been completed and there was some substantive information to review. At the December SWAB meeting, the SWAB requested a `decision- points' memorandum to make explicit the types of'decisions needed to build a solid waste plan. That memorandum and questionnaire on the decision points was distributed to the Work Group March 2 (attachment 3). Preliminary results of the questionnaire will be compiled and discussed in April then used again when discussing the analysis in subsequent meetings. Having a preliminary set of preferences and comparing them to a second set once the technical data are available may sharpen the decision making process. It now appears the analyses will be completed in late April and presented at the following Work Group meeting. Discussion Through preparation of the previous solid waste plan update in 2003, there was dissection among the jurisdictions on a number of key issues including whether to consider an in- County materials recovery facility and how to go about achieving the 61% waste reduction goal. A significant outcome was that the Town of Chapel Hill did not endorse the 2003 plan update. Another key outcome was that the County, as lead agency, did not firmly commit to a strategy to achieve the goal and, notably, removed its previous at least tacit support for a materials processing center as integral to meeting the waste reduction goal. As the various jurisdictions and the Solid Waste Advisory Board re- engage, the intent is to produce the statutorily required three year update of the State - required ten year solid waste plan, as well as develop a consensus around a workable, practical plan that achieves the waste 3 reduction goal. While staff believes plan development must be an iterative process, it is also useful to try to clarify at least generally, procedural and substantive steps in moving forward. Technical Assistance and Anal The staff has engaged its Departmental engineering consultant, Olver, Inc and their subcontractor Resource Recycling Systems Incorporated, to assist in technical aspects of the analysis of recycling collection and processing options, The collection options will compare dual stream to single stream collection in each of the three sectors — residential, multifamily and commercial - along with corollary issues of types of containers and automated to semi - automated collection. There will be a specific analysis of public v. franchised collection options for the commercial sector, as this is the least developed part of the County's recycling program. This analysis will be combined with an analysis of potential processing for recyclable materials — how much does it cost and what are the pros and cons of processing materials in- County with a County -owned and /or controlled facility compared to sending materials out to be processed by other private processors. Other possible work by staff Other important elements of the overall plan will continue to be worked on by staff at the direction of the Work Group including: • whether and how to include PAYT or mandatory recycling in the planning process, • franchising solid waste collection, particularly in unincorporated areas, • franchising solid waste collection in some or all.jurisdietions for non- residential waste, • multiple, jurisdictions working together to franchise waste and /or recycling services, • the future of drop -off sites and solid waste convenience centers wider changed solid waste and recycling collection options, • financing of the solid waste system, • soliciting and compiling public input. NOTE: Where we address franchising issues above, it is important to point out that in the upcoming legislative short session of the North Carolina General Assembly, Senate Bill 951, could be adopted. This bill would require local governments to pay any private haulers collecting waste or recyclables in areas in which they were considering collecting waste or recyclables beginning as soon as .July 1, 2006. Adoption of this bill as written, would require immediate action by Orange County and the Towns, outside the solid waste planning process considered below, to ensure passage of a local franchising ordinance which would preserve local governments' flexibility to franchise or outright collect waste and recycling without pre - paying private haulers who might already be working within the jurisdiction. Schedule and Process The staff has prepared a survey of decision points (attachment 3) that will provide the building blocks for development of a solid waste management system. The first iteration of the decision points survey will be completed without analytical data. Once data from the technical analyses are available to help the Work Group inform their decisions and ranked preferences for types of collection and processing, then they can begin development of a first draft of a system, 4 A series of decisions on recyclables collection methods will impact processing choices and there will have to be more feedback once the impact on processing is assessed. Plan development could go through several cycles including financial analysis, until there is an outcome that the work group wishes to put forward as the first draft of the system plan. Other elements to be included in the system include decisions such as whether or not to provide universal waste collection services and use of Pay As You Throw methods for financing residential waste collection. Once a whole system is established, it will be revised by the Work Group and then presented to the elected boards and the public for further feedback. Once the substantive recycling analyses are complete, they could be presented at a scheduled meeting of the Solid Waste Plan Work Group. The Work Group could then develop its straw plan including the other elements mentioned above and a financial analysis, and then present that to the various elected Boards. Following those presentations and subsequent revisions to the plan, in response to board feedback, would be one or more public hearings and a final draft to be prepared for the BOCC and other governments' approval and subsequent submittal to the State. This process could take the remainder of the current calendar year. There are then several steps to putting this draft forward that could be taken in a variety of sequences. It will be a Work Group decision on the sequence. Thus the order of the steps below does not reflect any preference, just enumeration. I. Complete draft plan after receiving technical reports, conducting internal debate, further analysis and discussion. Planning level estimates of financial aspects will be included for the straw plan. 2. Take complete draft plan to each jurisdiction for presentation to the elected boards and their constituencies. We believe this effort should be led by the elected officials and SWAB representatives from each.jurisdiction, with solid waste staff providing technical backup. 3. Work Group and staff revise the resultant plan and present to the public in a public hearing or series of hearings. This phase would include other public education including articles in the newspapers and on the County web site as well as possible radio interviews or other media coverage, At least one public hearing is statutorily required for this process 4. Reconsider the plan in light of public continent, 5 Develop a more precise financial model of the selected plan including revenue sources and levels. 6, Revise plan as needed to meet BOCC requirements, T Get final approval from all,jurisdictions. 8. Submit to the State. 5 Frankly, the only things we are certain of in the sequence are item one being first and item eight being last, The other six items could be subject to a variety of sequences and we believe the next Solid Waste Plan Work Group meeting should consider this procedural sequence and provide some direction on the staff work they need. We believe one focus of the Work Group could be on items that relate to individual jurisdictions' control of waste, specifically PAYT, mandatory recycling, and franchising, While we recognize these are potentially important elements of the solid waste system, arguments could be made that they are solely the responsibility of each jurisdiction and not of the Solid Waste Department. Therefore each jurisdiction could implement at its own discretion. Conversely, implementing for example PAYT in only one jurisdiction would potentially have effects in other jurisdictions that they have to react to. If the Town of Chapel Hill implemented PAYT alone, then the County might have to restrict use of solid waste convenience centers in some way by providing PAYT there, which would cause the County to reassess its method of tax -based financing of these centers. Summary The Solid Waste Plan Work Group began meeting in April 2005 to begin a planning process that would result in adoption of the three -year update to the State - required ten year solid waste management plan for Orange County. The Group has laid out its concerns, received a series of staff technical reports explaining aspects of the current solid waste and recycling system and requested additional information to inform their future decision - making. While the Work Group last met in November, the SWAB and staff have continued to examine details of the solid waste management system over the past three months. In the coming months, the Work Group will complete a decision - points survey, evaluate its results, receive additional techmical analysis and craft a draft plan and time line for submittal to the elected boards and the public for consideration.

The plan for using this questionnaire is that all Solid Waste Plan Work Group members will complete it, electronically if possible, and return it to staff with any additional comments by March 23. The completed questionnaires will form the basis for the April Solid Waste Plan Work Group meeting to further develop its ideas, positions and possible consensus on these decision points as well as other decision points that may arise through discussion and further comment from the Work Group. In your response please indicate what dates in April and May you are available for meetings exclude week of April 3-7. We expect completion of a technical report on primarily the recycling portion of the County's scope of work due at the end of April. We expect to schedule a presentation of that work in May for the Solid Waste Plan Work Group, Once you receive the report, you will, at the subsequent Work Group meeting, have an opportunity to reconsider the responses to the questionnaire in light of data presented in the report. We realize that some of the questions are better answered with data the technical report in hand, while some, such as developing ranking preferences, may be better made before the data are presented. Feel free to answer all or some of the questions this first time as a way to express initial preferences; once you get data you may change your mind on some of them. Group consensus may shift. You may choose to not answer those that are more data - driven until you get the data; that's fine too. There is a lot of indecision right now, as no data on projected program performance has been presented, eg, single stream v, dual stream cart v bin. Use of the decision points tool is a two -step process. The first iteration allows representatives of the various entities to express what they want at this point and to a certain extent, we will use that to push against the recycling technical analysis. Then we'll do a second iteration once the data are in and come to consensus about the system we recommend. It will be important for all jurisdictions to express their preferences particularly in the part VII B of the questionnaire that pertains specifically to them. Work group members from outside the particular jurisdiction may express their preferences for solid waste management techniques in communities other than their own, but the opinions of those representing that jurisdiction will have most importance. The exception to this is that all members are able to comment on solid waste management needs for the unincorporated area because all are residents of Orange County and all pay taxes to support the current system of convenience centers. Please respond to the questionnaire along with any comments you may have on it, preferably electronically, and return to Blair Pollock of the staff by March 23 so he can prepare a summary of responses for presentation at the as yet unscheduled Solid Waste Plan Work Group meeting to be held in April. Decision Points Requiring Solid Waste Plan Work Group Recommendations This document lays out a series of decisions that must be made to continue development of the updated solid waste management plan. Those decisions will provide guidance to the staff on how to conduct the detailed analysis needed to bring back specifics on how various solid waste and recycling systems might perform fiscally and in terms of the tonnage of materials managed by each element of the system e.g. dropoff recycling, residential solid waste collections, etc. Since the Solid Waste Plan Work Group began its effort last April, they have reviewed descriptive data from the various recycling programs operated by the County and learned about the potential for further waste reduction through a detailed examination of recyclables remaining in the waste stream. The Work Group has also learned about various recycling collection and processing concepts and options that could be involved in advancing our County's recycling efforts. Considerable additional analysis is underway and will continue through the spring, when the Work Group will begin formulating recommendations. We anticipate results of our technical analysis to be available in May and plan to schedule a presentation when the technical analysis is complete At this point, the staff is presenting the Work Group with this decision - making framework for a preliminary opinion forming exercise. We do not expect you to answer all the questions presented without more data, but do answer as much as you like to help create a bounded useful discussion at the April meeting. As you answer the questions, critically review this document with an eye towards ensuring that the questions being asked get us the answers we need to develop a comprehensive, integrated solid waste management plan that reflects the priorities and desires of the County and its municipalities regarding the future of waste management. We urge you to answer at least those questions that do not require data e.g. ranking of the importance of various criteria to decide where and by whom materials should be processed. Staff believes that the criteria should be established and ranked prior to seeing the data so that the data don't drive what we believe should be values -based decisions, You will see the questionnaire again when the data are analyzed and continue to use it for decision- making. Many critical items in this summary are currently under analysis. Once the analysis is complete the number of items will likely be reduced. One thing to keep in mind is that all of these items are interconnected and interdependent. While we may look at residential collections separately, in the end decisions made in processing or even multi- family collection may dictate the residential course. Development of the solid waste plan will be an iterative process that will be informed by the data from the upcoming analyses along with the judgments of the Work Group and staff We anticipate being able to present a planning document to the Towns and County later this year based on the decisions taken from this document For the past several months the Work Group has been involved in reviewing and discussing the many different alternatives for managing solid waste in the County, particularly as regards reducing solid waste in the most effective and efficient manner. Considerable data and reports have been presented and discussed, but to date no recommendations have been made. The SWAB has continued focusing on elements of a new plan in the absence of recent formal Work Group meetings. Affiliation The breakdown is by sector. Please circle your response and for the few questions requesting additional information please so respond: I, Waste Reduction Goals- The County has been working towards a 61 % waste reduction goal. This goal is ambitious, but appears to be achievable considering that we are currently at 45% (2005). The staff has presented information that 54% is a reasonable step based on the recyclables materials matrix provided earlier. This assumes that additional investment and commitment is provided in support of these goals. Should the County keep its waste reduction goal of 61 %?

Budgets and Financials/ Fee Changes — Decision Points to be developed at a later point. 23 Attaclunent 3 Orange County Solid Waste Management Plan Reconsideration /Review Process The current adopted Orange County Solid Waste Management Plan contains several components. The component that is the focus of this planning document is the waste reduction goal, including the operational /financial means to achieve that goal. In the most recent BOCC approved Solid Waste Management Plan that was submitted to the state earlier this year, a number of substantive changes were made from earlier approved Plans relative to future waste reduction strategies. While the waste reduction goal of 61% was maintained, virtually all of the waste reduction and recycling program improvements /expansions were eliminated. This memorandum discusses how the County could reestablish a long -term waste reduction plan that is acceptable to the stakeholders and is aimed at achieving the adopted 61 % goal. Suggested participants in the process include: • Solid Waste Advisory Board • Board of County Commissioners • Carrboro Board of Alderman • Chapel Hill Town Council • Hillsborough Town Board • Citizens • Staff At the February 8 Board of County Commissioners' Work Session the BOCC indicated that the SWAB should take the lead role in development of a revised Solid Waste Management Plan. The SWAB intends to initiate a plan development process that involves the key stakeholders, especially interested elected officials. The SWAB will request each,jurisdiction appoint at least one elected official to become part of the SWAB Solid Waste Plan Work Group. UNC would also be invited to send a representative to the Work Group. The SWAB Work Group would meet periodically (at least monthly and occasionally more often) over the course of a year to review and discuss staff work and provide guidance. Additionally, these members would keep their own boards' apprised of the progress and key issues relative to the planning process. The following represents an outline of a timeline and process that could be followed to: • reexamine and reconsider the portion of the Plan that serves as the means by which the 61% goal could be achieved, including • residential and commercial recyclable material collection methodologies • equipment and staffing • adding new materials and marketing • regulatory issues • material processing options • financial impacts and funding requirements for the enterprise find • implementation issues El receive input fiom the SWAB, the Town's, the public, and the BOCC, and prepare a recommended revised Plan and have that revised Plan considered and adopted by the three Towns and the BOCC before the next 3-Year Update to the State required plan is due on June 30, 2006. Suggested Timeline 2004 November- December -Solid Waste staff to examine and identify a scope of work and timeline necessary to reexamine and analyze future waste reduction policy (including recyclables collection and processing options). Staff begins information gathering and analysis and discussions with the SWAB that will continue throughout the process. 11R February — Staff presents to the BOCC a proposed process and timeline to conduct a study reconsidering the County's long -tern waste reduction strategy, including specific issues previously raised by the Towns of Chapel Hill and Carrboro. Staff receives guidance and proceeds to implement approved process /timeline, March — Staff discusses approved process with SWAB and defines and discusses the SWAB's role in the process. (SWAB will discuss as necessary at any scheduled monthly meeting or at a special meeting if desired). A letter- will be sent to the four jurisdictions requesting appointments to the Work Group. March /April - Work Group is fornned and meets to receive progress update and review work to date, discuss their role and degree of involvement in the process, and to provide guidance /input to the process. April — Staff provides status of process to the Assembly of Govermments, including discussion of Interlocal Agreement provisions regarding long terns planning policies. August/September — Work Group meets as necessary. September - SWAB provides status update to BOCC and Town Boards (if desired). Public education conducted on the newly proposed Plan elements. October — SWAB sponsors open forum for citizen input. November /December — Staff submits preliminary draft of recommended revised Plan to Work Group and SWAB.

April — SWAB submits final draft of Plan to Towns. Towns provide feedback, Requests for any substantive changes by Towns will be shared with BOCC. (This could be done at AOG meeting, if desired) May— Towns endorse revised 3 -Year Solid Waste Management Plan Update to State, which includes revised waste reduction and recycling component. June — BOCC endorses revised 3 -Year Solid Waste Management Plan Update and authorizes submission of 3 -Year Plan to State (Due June 30). Summer — Staff prepares comprehensive implementation plan for adopted Solid Waste Management Plan, including financing, capital, and operational elements. 26 -P� LANDFILL GAS axc"r ' FEASIBILITY STUDY ►n_AM:�z�1�z� Prepared for: Orange County, North Carolina ® MMk�'Gfi:1 ri® Orange County PO Box 17177 Chapel Hill, NC 27516 -7177 Prepared by: I%a� //, a`` Olver Incorporated OLVERCharlotte, NC 282It lard, Suite 505 INCORPORATED Project Number 20151 1.0 INTRODUCTION One of the major components of Orange County's (County) integrated solid waste management system is the municipal solid waste (MSW) landfills, MSW contains significant quantities of organic materials that produce a variety of gaseous products when anaerobically decomposed in a landfill. Anaerobic bacteria produces significant quantities of carbon dioxide and methane gas Landfill gas also commonly contains trace amounts of hydrogen sulphide, me captans, vinyl chloride, and numerous other volatile organic compounds Landfill gas represents both an environmental liability and a unique renewable energy resource. The methane component of landfill gas contains energy that can be used to generate electricity, heat buildings, or fuel for industrial processes. Utilization of energy from landfill gas not only aids in the control of local environmental impacts but also avoids consumption of fossil fuels that would otherwise be required to generate an equal amount of energy 2.0 ENERGY RECOVERY OPTIONS The primary objective of a landfill gas -to- energy project is to convert landfill gas into a useful energy form such as electricity, steam, supplementary or replacement boiler fuel, or pipeline quality gas. There are several technologies that can be used to maximize the value of landfill gas when producing these energy forms; the most prevalent of which are: • Direct medium -Btu gas use • Power' production /cogeneration Sale of upgraded pipeline quality gas The most advantageous form of energy for a particular landfill will depend upon a number of factors including the existence of available energy markets, process technology requirements, and project development and operation costs. This study focuses on the key elements that determine a project's preliminary economic feasibility and, more specifically, on -site specific design issues related to direct use of gas and /or power production since these are the most common landfill gas recovery options. 2.1 Sale of Medium -Btu Gas The simplest and often most cost - effective use of landfill gas is as a medium -Btu fuel for boiler or industrial process uses (e g., drying operations, kiln operations, cement and asphalt production, etc) For this type of project, the recovered gas is piped directly to a nearby customer where it is used in new or existing combustion equipment as a replacement or supplementary fuel. Orange County 1 March 2006 Draft 2.2 Power Generation The most prevalent use for landfill gas is as a fuel for power generation with the electricity sold to a utility and /or a nearby power customer. Power generation is advantageous because it produces a valuable end product — electricity — from the waste gas. Facilities that use landfill gas to generate electricity can qualify as a "small power producer" under the Public Utilities Regulatory Policy Act (PURPA), which requires electric utilities to purchase the output fi'om such facilities at the utility's avoided cost The electricity can in some cases be used on site to displace purchased electricity or be sold to a nearby electricity user (c g., municipality, industrial, etc.) Cogeneration (electric power with waste gas heat recovery) is an alternative to the production of electricity only Thermal energy cogenerated by landfill gas projects can be used on site for hearing, cooling and /or process needs, or piped to a nearby industrial or commercial user to provide a second revenue stream to the project. 2.3 Upgrade to High -Btu (Pipeline Grade) Natural Gas Another option is to upgrade the landfill gas to a high -Btu product for compression and direct introduction into a natural gas pipeline. This application requires extensive high technology treatment of the gas to remove CO, and other impurities In addition, gas companies require that gas injections into their pipeline systems conform to strict quality specifications, which can impose additional quality control, cleanup, and compression requirements on the producer. However, this can in some cases be an attractive option since it is possible to utilize all the gas that is recovered. XM il] 11 �111�]O]fP__I Determining the optimum size for a landfill gas recovery project requires a careful balance between maximizing electricity In and /or direct landfill gas use while minimizing the risk of insufficient gas supply in later years. The challenge arises because landfill gas production rates change over time Gas generation may be increasing at an open landfill or decreasing at a closed landfill. Other considerations such as existing and future electricity rates, equipment cost's, and any penalties for shortfalls in electricity output must be factored into the system design. The optimum design and operating scenario for a particular landfill gas project is likely to fall somewhere between two general scenarios: (1) minimum gas flow design; and (2) maximum gas flow design However, a third design scenario — a modular approach — may be used at landfills where gas flow rates are expected to change substantially over time For the purposes of this study, a minimum gas flow design was used in the evaluation of potential landfill gas recovery alternatives The combined total production of gas from both the North and South Eubanks Road landfill sites and the production from the South Eubanks site only were respectively evaluated. Orange County 2 March 2006 Draft !i _100= ­111' Gi DIE[ [,—Eli loon i'dli_000 Based on a review of existing potential energy users in the immediate vicinity of the Eubanks Road solid waste management facilities, it was determined that power production and/or high -Btu gas production were the most feasible alternatives available at this time No significant medium - Btu customers (i.e., customers with an existing boiler or combustion system that could direct fire landfill gas) were identified in immediate proximity to the Eubanks Road site It is assumed that if a school or similar type energy user is constructed in the area that the option of using landfill gas for heating and electricity (cogeneration) rather than direct firing of a medium Btu gas would prove to be the most beneficial use. 4.1 Electric Energy (Power) Production Several proven technologies exist for generating power — internal combustion engines and combustion turbines (microturbines). A typical landfill gas -to- electric energy installation has the following components: • Landfill gas collection system Landfill gas compressor(s) • L,andfill gas pretreatment equipment (for moisture, siloxanes, and particulates removal) Microturbine, boiler/steam turbine, or Internal Combustion Engine Generator • Motor control center Switchgear and step -up transformer Waste gas beat recovery (cogeneration option) 4.1.1 Internal Combustion Engine The reciprocating internal combustion (IC) engine is the most commonly used conversion technology in landfill gas applications — almost 80 percent of all existing landfill gas projects use them. The reason for such widespread use is their relatively low cost, high efficiency, and good size match with the gas output of many landfills. IC engines are relatively efficient at converting landfill gas into electricity 4,1.2 Microturbines Microturbines are an emerging landfill gas energy recovery technology option, especially at smaller landfills where electric generation plants are not generally feasible due to economic factor's and lower amounts of landfill gas Microunbine technology is based on the design of much larger combustion turbines employed in the electric power and aviation industries Microturbines generally operate as follows: Orange County 3 March 2006 Draft Fuel is supplied to the combustion section of the microt ubine under medium pressure. Air and fuel are burned in the combustor, releasing heat that causes the combustion gas to expand • The expanding gas powers the gas turbine that in turn operates the generator; the generator then produces electricity. • To increase overall efficiency, microturbines are typically equipped with a recuperator that preheats the combustion air using turbine exhaust gas. A microturbine can also be fitted with a waste heat recovery unit to heat water_ 4.2 High -Btu (Pipeline Grade) Gas Production The following treatment technologies are typically used to produce landfill gas of similar quality to natural gas. However, it is sometimes necessary to employ a combination of these technologies to obtain the desired quality. The most commonly used technologies to upgrade landfill gas quality are water absorption and PSA (pressure swing adsorption), which uses active carbon. The PSA process was assumed as the gas treatment technology for this study. 0[—i M]i -I.1 111FIII nI 11 li I� I I's the estimated methane generation and energy production capacity of the County's two landfills were based upon the estimated emissions results using the Environmental Protection Agency's (EPA) landfill gas emissions model LandGEM. This model uses a first - order decomposition rate equation for quantifying emissions from the decomposition of landfilled waste in MSW disposal facilities_ The combined methane generation rate fron both disposal facilities is estimated to peals at approximately 410 cubic feet per minute (CFM) in the years 2008 to 2010 and, subsequently, decline to approximately 180 CFM by the year 2030. Orange County 4 March 2006 Draft The primary customers identified as potential energy users for a landfill gas -to- energy project at the Eubanks Road site are the County, Duke Power, and PSNC Energy, The County would primarily use power and /or waste gas heat from the electric generation gas combustion process for the proposed operations building, transfer station, and other on -site power and heating uses Given the relatively low projected on -site usage of available electrical energy, it was assumed that all electric power generated from the project would be sold to Duke Power and that the County would buy back electricity for its needs The cogeneration potential (exhaust gas heat recovery for building and /or water heating, etc.) was not factored into the project economics at this time because of the lack of a large user like a school, industrial process, or commercial building complex in the immediate area. If plans to construct a new public school complex and animal shelter in the area are implemented, the economics of landfill gas recovery should be reevaluated with respect to cogeneration of electricity and heat for these additional needs (i.e., energy demands in addition to the proposed transfer station, operations building, and other existing on -site uses already factored into this preliminary landfill gas recovery feasibility analysis). Cogeneration may potentially lower overall energy cost's while using waste heat for internal building(s) uses and providing clean, complete combustion of the waste gases. Direct sale of pipeline grade gas to PSNC Energy was considered under the high -Btu gas production alternative. The following power and gas production alternatives were considered. Option I — Power Generation using Microturbine Technology — Utilization of combined gas flow from both the North Eubanks and South Eubanks MSW Landfills Option 2 — Power Generation using Microt'urbine Technology — Utilization of gas flow from South Eubanks MSW Landfill • Option 3 — Power Generation using Internal Combustion Engine Technology — Utilization of combined gas flow from both the North Eubanks and South Eubanks MSW Landfills • Option 4 — Power Generation using Internal Combustion Engine Technology — Utilization of gas flow from the South Eubanks MSW Landfill Option 5 — Production of Pipeline Grade Gas using Pressure Swing Adsorption Technology — Utilization of combined gas flow from both the North and South Eubanks MSW Landfills Based on the projection of annual costs and revenue, a net operating loss is anticipated for each power generation option over the life of the project (2007 to 2030) Losses for Options 1 through Orange County 5 March 2006 Draft 4 range from a low of approximately $128,000 in 2007 to $205,500 in 2020. The projection of electric revenues is based upon Duke Power's fixed long -term (15 -year) rate schedule (Schedule PP -N (NC), Non - Hydroelectric Qualifying Facilities - Purchased Power). Production of Pipeline Grade Gas (Option 5) shows an initial breakeven projection; however, a significant downside potential (operating losses of anywhere from $497,500 to $937,500 during the 2020 to 2030 period) exists in the later years of the project resulting from the reduction in gas flow from the disposal facilities as the waste decomposition is advanced. Based upon the County's preliminary discussions with Mr, Jerry O'Keeffe, PSNC does not allow any connection to their system by small suppliers, In all cases, it was assumed that the County would own and operate the proposed landfill gas recovery facilities. The results of the economic evaluation are summarized in the following table.

If development of the proposed school complex or other significant energy user occurs in the immediate vicinity of the Eubanks Road site, the feasibility of landfill gas recovery would be significantly improved given the potential for this type of facility to make use of both the electricity and heat created during power production. In this situation landfill gas could become a clean efficient energy source rather than an environmental liability even when generated in relatively small quantities as projected for the Eubanks Road disposal sites. Given the beneficial impact of additional energy use on the feasibility of landfill gas recovery, the County should further evaluate landfill gas utilization in the design of the school(s), animal shelter, and /or other proposed facilities for electric and heating purposes. The following additional information relative to each potential user will be required in order to provide a more comprehensive evaluation of landfill gas use potential from the existing Eubanks Road site: proposed facility implementation schedule, start -up date, heating loads, electricity demand, seasonal load and demand variations, sustainable landfill gas production, and availability and costs of supplemental fuels By producing electricity and heat during power production, microtubine technology is highly suited to landfill gas recovery applications, and is considered an emerging system technology that is likely to improve in terms of economic feasibility as the result of ongoing product development and commercial use experience (landfill gas -to- energy). The microturbine offers the following advantages when compared to other types of landfill gas utilization and power generation technologies: Portable and Easily Sized — Microturbines are modular and available in incremental capacities for multiple -unit stacks, so that single or multiple microturbines can be configured to adapt to gas flow and satisfy on -site power requirements. Orange County 8 March 2006 Draft Flexibility — Microturbines may be a more viable option at smaller and older landfills where landfill gas quality and quantity would not support more traditional landfill gas electric power generation technologies. They may also be feasible at larger landfill gas projects that have excess unutilized gas,. Compact and Fewer Aloving Parts — Microturbines are approximately the size of a large refrigerator and require minimal operation and maintenance. The use of air bearings coupled with an air - cooled generator eliminates the need for lubrication and liquid cooling systems. Lower Pollutant Emissions — Microturbines burn cleaner than comparable r'ecipr'ocating engines For example, NOx emissions levels from microturbines are typically less than one -tenth those of the best performing reciprocating engines and lower than those from a landfill gas flare Capable of Conrbrr.sting Lower- Methane - Content Landfill Gas — Microturbines can operate on landfill gas with .35 percent methane content and perhaps as low as 30 percent. • Ability to Generate Heat and Hot Water — Most microturbine manufacturers offer a hot water generator as a standard option to produce hot water (up to 200 °F) from waste heat in the exhaust. This option can replace relatively expensive fuel, such as propane, needed to heat water in colder climates to meet space - heating requirements. The sale or use of tnicroturbine waste heat can significantly enhance project economics. Orange County 9 March 2006 Draft
