BACKGROUND: At their May 18, 1996 meeting, the Landfill Owners ' Group requested that each governing board provide feedback to the LOG by the end of June concerning their views about several important implementation issues related to the integrated solid waste management plan. Specifically, the LOG asked that the Board of Commissioners provide comments at this point about : a) the overall solid waste management system studied by Weston, Inc . and recommended by the LOG. b) selecting unit-based pricing ("pay per throw") vs . collection bans (mandatory recycling) , coupled with differential landfill fees, as the primary waste prevention strategy. Public education would be coupled with either of these strategies. c) whether universal collection would be adopted for both recycling and solid waste collections county-wide, or whether a system of convenience centers and "laissez faire" private collections would be maintained in the unincorporated areas and for widespread commercial recycling. The attached LOG staff memo presents some of the advantages and disadvantages of various implementation issues, from the staff perspective. County staff prepared the chart on page 13 that compares some of the estimated costs associated with the current residential solid waste management system in unincorporated Orange x 2 County (6 staffed solid waste sites, voluntary/self-paid use of private haulers by individual residents, selected curbside recycling service, and dropoff recycling service) , vs . a universal collection system. County staff will provide an explanation of these cost estimates, and County and LOG staff will be available to respond to Board questions about the three subjects concerning which the LOG has requested feedback. RECOMMENDATION: The Manager recommends that the Board discuss and formulate specific recommendations to the Landfill Owners ' Group, either now or at a subsequent date, concerning the integrated solid waste management plan implementation issues identified in the June 13 , 1996 LOG memo. , . 3 MEMORANDUM TO: Carrboro Mayor and Board of Aldermen Chapel Hill Mayor and Town Council Hillsborough Mayor and Town Board Orange County Board Chair and Commissioners FROM: Don Willhoit, Landfill Owners Group Chair DATE: June 13, 1996 SUBJECT: Selecting an integrated solid waste management system At their May 18 meeting, the Landfill Owners Group established an outline of an integrated solid waste system for the member governments to consider. This outline is similar to the system previously selected by the Owners Group. The Owners Group requested that the member governments review the proposed system and recommend changes by July 1. The Owners Group will receive comments at their July 11 meeting. The Owners Group requested that the local governments do the following: 1. Review the system as recommended and recommend any changes. 2. Provide feedback and recommendations on selecting unit-based pricing v. collection bans (mandatory recycling) coupled with differential landfill fees as the primary waste prevention strategy. We note that either of these strategies would be coupled with public education. 3. Determine whether universal collection would be adopted for both recycling and solid waste collections county-wide or whether a system of convenience centers and laissez-faire private collections would be maintained in the unincorporated areas and for widespread commercial recycling. Summary This memorandum contains additional information on the Owners Group recommended system, unit-based pricing versus collection bans, and universal collection which may be helpful in addressing the three items requested by the Owners Group. Background The preliminary system selected by the Owners Group includes the following: 2 Waste Prevention: Note: select either unit-based pricing or collection bans to implement first • Unit-based pricing (volume or weight based) OR • Collection bans (Mandatory Recycling) • Differential Landfill Fees NOTE: Differential fees for a broad range of materials could be coupled to collection bans. Fees for selected items such as construction wastes could be implemented without the collection bans. • Non-economic incentives • Public Education NOTE: This would be integral to all other options. collection: • Universal collection of waste and recyclables except no rural yard waste collections, • Collection of solid waste by individual governments, collection of recyclables by Orange Regional Landfill/Orange Community Recycling or its successor agency, • Collection of commingled recyclables, • Elimination of convenience centers for solid waste collection in unincorporated areas, • Creation of two (or more) special waste centers for all materials except mixed solid waste. i.e. yard waste, bulky items, salvageable items, recyclables, used motor oil, tires, auto batteries. Processing: • Materials Recovery Facility for sorting and processing of mixed recyclables as well as source separated recyclables. This facility would not accept mixed solid waste. • Centralized composting facility for composting of some yard waste products and other compostables such as non-marketable, residual paper sorted out from Materials Recovery Facility. We note that Triangle J Council of Governments is working with area waste water treatment plants to develop a biosolids (sewage sludge) composting facility that could accept other 3 organic material such as unmarketable paper, yard waste and food wastes (see attachment 2) . We believe that the materials recovery facility is a cornerstone of this system and work on it should begin early, if this system is adopted. The composting facility does not necessarily need to be constructed early in the process to handle either yard waste or residual paper from the materials recovery facility. Yard waste is now adequately handled through the mulching process at the landfill. Residual mixed paper may have other markets as both sorting technology and end-use markets improve. Implementing the Plan and Reorganization of Solid Waste Management The Owners Group recommended proceeding with plan implementation prior to finalizing the structure and functions of the solid waste management reorganization. I forwarded a memorandum concerning the reorganization process to all governing board members last week. The proposed timetable calls for development of an agency by January 1997 with implementation by July, 1997. While proceeding with the plan absent a new governing structure is theoretically possible, it would require considerable ongoing coordipation of waste reduction activities by each government to ensure that the solid waste plan remains integrated. Discussion Owners Group member governments will need to make at least three key decisions in order to proceed with implementation of an integrated solid waste management plan. These decisions are only the first steps towards plan implementation. WESTON"s final report chapter 5 on plan implementation guidance details many of the types of decisions that must occur in order to fully implement the plan. This section reviews the first set of key decisions and presents some advantages and disadvantages of each approach. 1. Decide on the structure of the overall integrated solid waste system as presented above and make any desired changes. 2. Select between unit-based pricing and collection bans (mandatory recycling) coupled with differential landfill fees as the main mixed solid waste prevention strategy. The WESTON study considered implementation of all five prevention measures listed above. The Owners Group recommended implementation of public education and non-economic incentives. They requested that the member governments select either a unit-based pricing system or a collection ban (mandatory recycling) system plus differential landfill fees. Either of these strategies would accompany public education as the primary waste prevention measures. 4 It is theoretically possible to implement both unit-based pricing and collection bans simultaneously or to implement different measures in each jurisdiction. However, we believe that the effort required and the accompanying public education and awareness would make a choice between the two approaches a more practical approach. The other measure could be phased in, if desired, at a later date. We believe it is possible to use different strategies for different economic sectors. For example collection bans could be instituted in the residential sector where each can of waste is easily observed. At the same time, unit-based pricing could be instituted in the multifamily and commercial sectors where it is more difficult to observe the contents of the waste and where fee for service is more common. Unit-based pricing systems: These types of systems are becoming more prevalent throughout the country; over 3, 000 are now in place. Most of the recently implemented systems apply primarily to the single family residential sector and- most are tag or bag-based. Some are based on size or number of cans or carts. There are a few weight-based systems in place, but they are largely experimental and the technology is still being perfected to weigh solid waste "on board" the truck. Use of a weight-based or cart-based system also assumes the existence of a sophisticated billing system. Reported Waste Diversion Various cities that have implemented unit-based pricing after having had recycling in place report reductions in weight of residential mixed solid waste of 8% to 13%. Other locations where both recycling and unit-based pricing were implemented simultaneously report reduction rates in mixed solid waste in the 30% to 40% range. When unit-based pricing systems are used in the multifamily and commercial sectors, the dumpster volume and frequency of collection are the primary basis for billing. Virtually all private commercial haulers use some volume-based rates to determine the fees to charge for collection. There is little to no direct impact on the tenants of a multifamily or office building from this type of system and no readily available method to create an impact. Setting Svstem Goals System goals should be established to determine the pricing structure. Goals to consider include: What portion of the costs of collection, processing and disposal will the fees cover? 5 Will the fees be levied on only waste or waste and recyclables? Are the fees to provide an incentive for waste reduction and recycling? While these goals are not mutually exclusive, ranking them in importance would have an impact on the fee structure. There may be other goals that the governing bodies and Owners Group should consider. Advantages of Unit-Based Pricing: • Uses economic incentives to change solid waste generation behavior and increase prevention/recycling, • Enables raising of funds specifically related to solid waste collection activities, • Distributes costs of solid waste system according to use, • Enables development of a rate structure to achieve certain goals e.g. cost recovery, diversion of materials from solid waste, sending a "message" about solid waste costs, • Offers flexibility to system users and administrators in consumption choices and policy making/fee setting. Disadvantages of Unit-Based Pricing: • Potential for illegal disposal to avoid payment of fees, • Uncertainty in revenue generation depending on user behavior and unit costs (e.g. if there is a lot of recycling, prevention, and/or illegal dumping the revenue from sale of bags or stickers may not cover costs as projected) , • System set-up costs and rate structure development are significant tasks. Professional technical assistance could be necessary to establish rate structures and billing systems, • It is potentially difficult to achieve response to this system from tenants of multi-tenant commercial or residential buildings since costs are primarily borne by the owner, not the tenant. Hauling fees are usually built into the rent and do not vary. Thus there is no individual "reward", 6 • Financial savings from waste reduction may be cancelled out for residents by the non-deductibility of garbage fees from federal taxes where local property taxes are deductible. • Can be perceived as an additional tax, especially if taxes are not reduced when unit-based pricing is implemented. Collection Bans (Mandatory Recycling) With Differential Landfill Fees An alternative to unit-based pricing fees as a primary waste prevention strategy is collection bans (mandatory recycling) . These bans could be applied to a variety of materials in a variety of sectors. The bans could be most effective if coupled with differential fees at the landfill. Thus, those haulers who choose not to enforce collection bans would still be subject to penalties if their loads are in violation of landfill regulations. • This combination of collection bans and differential landfill fees is now in place in Orange County for commercially generated, recyclable corrugated cardboard and all yard waste. Reported Waste Diversion Compared with unit-based pricing fees, fewer communities that we are aware of, have instituted widespread collection bans. Locally, Alamance County reports a 34% decline in waste generation with their collection ban/differential landfill fee system. The system was instituted at the same time as recycling programs. Mitchell County has instituted collection bans at sanitation sites. They report a 40% waste reduction at those sites. Islip New York reports a 95% recycling bin set out rate and diversion of 48 pounds of recyclable containers and paper per household per month. That recycling rate is double our local residential recycling rate. Our anecdotal research with other communities who have used these bans for longer periods seems to show that if enforcement or education efforts are reduced, compliance with the bans drops. When enforcement is stepped up, compliance increases. Advantages of Collection Bans • Easy to implement and understand. • Can be enforced at the point of disposal. • Applies equally to all generators. 7 • Greater potential for diversion if enforcement level is high and maintained over time. Disadvantages of Collection Bans • Enforcement requires regular and continuing inspection of solid waste containers for violations that will require either additional personnel to maintain the present solid waste collection productivity. NOTE: Islip, New York, which has mandatory recycling, reports use of 7 inspectors to police 78, 000 households plus one supervisor. The inspectors also handle solid waste complaints. • Enforcement with no alternative means for handling banned materials may lead to resistance to the program and illegal dumping. • Difficult to determine if those using dumpsters are in compliance since most material is bagged in opaque garbage bags. • Inflexible in the face of changing markets and processing technologies for different materials that may or may not be subject to the initial ban. • Requires subjective judgment on the part of each solid waste collector and landfill inspector regarding tolerance levels, i.e. How many cans are too many? Was paper mixed with solid waste contaminated at the source or when it was mixed into,the waste? • Regulatory approach may be resisted by the public. 3. Decide whether to provide universal collection of solid waste and recyclables or to continue current drop-off site collections. The system recommended by the Owners Group includes universal collection of solid waste and recyclables. Currently universal collection of solid waste is provided to the urban residential, multifamily and commercial sectors. Universal collection of recyclables is provided to the urban residential sector and most multifamily units. Universal collection of solid waste and recyclables currently does not exist for the unincorporated residential sector; however solid waste convenience centers are provided for self-hauled disposal of waste. Also universal collection of recyclables does not exist in the commercial sector. Change to a universal collection system would have the most impact throughout the unincorporated area followed by the commercial sector. A summary table of how services are provided in each jurisdiction is attachment 1. 8 Advantages of Universal Collection • Provides more control of waste and recycling collections than an open system, • Provides similar, equitable service to all customers, • Makes recycling easier and more convenient than self-haul, • Possibility of integrated service with existing fleets in some sectors e.g. commercial service in unincorporated areas might be able to be provided from existing incorporated commercial fleets, • Ability to provide recycling in the commercial sector which has the largest untapped potential for diversion. • Assures consistent enforcement of bans or assessment of fees in the unincorporated areas. Disadvantages of Universal Collection • More costly than current collection system. Presently the collection system is not universal, providing curbside collection to all households in the county would raise the level of service to citizens but also increase total system costs. Current system costs do not include the costs to citizens for self-hauling their waste to convenience centers for disposal. There is some demonstrated support in unincorporated residential sector for retaining solid waste convenience sites. • Drop-off recycling sites are eliminated thus reducing flexibility for diversion programs. Recommendations We recommend that the member governments of the Owners Group consider the integrated solid waste system proposed by the Owners Group, recommend any changes and resolve the following issues: 1. Review the Owners Group recommended system and recommend any necessary changes. 2 . Selection of either collection bans (mandatory recycling) with differential landfill fees or unit-based pricing systems for prevention. 3 . Determine whether universal collection for all solid waste and recyclables is the best type of collection system. The Owners Group has requested that the governments discuss and resolve these issues by July 1 so they can finalize the system at their July 11 meeting. 9 Attachment 1 Summary Table of Solid Waste and Recycling Services.

Last fall, several jurisdictions within the TJCOG region decided to undertake a joint study of the feasibility of a regional composting facility for handling biosolids remaining as a result of the wastewater treatment process. The Towns of Apex,Cary,Clayton,Garner,and Zebulon;the City of Durham;the County of Durham;and Orange Water and Sewer Authority (OWASA) subsequently contracted jointly with TJCOG and E&A Environmental Consultants,Inc. to produce the resulting study report, "Regional Biosolids Composting Feasibility Study—Final Report," dated March 28, 1996. Based on this report,it is evident that local governments can realize several benefits through a cooperative interlocal approach to biosolids composting: significant economies of scale in constructing,operating, and maintaining such a facility;economies of scale and minimized competition in marketing the compost product to end users;an invaluable biosolids management option for those periods when inclement weather or other conditions prohibit the use of conventional land application as a method for biosolids disposal;and extended life for municipal solid waste landfills due to the opportunity to compost with the biosolids other organic material. The cost projections in the study report indicate that,for some jurisdictions,composting biosolids at a publicly owned regional facility could be economically competitive with current methods of biosolids disposal. Based on these cost projections, the Town of Cary and OWASA have to date formally committed to further evaluate the economic, technical, environmental, and institutional feasibility of establishing a publicly-owned regional biosolids composting facility using an aerated static pile composting technology. More specifically, these entities are currently working with TJCOG to develop (a) a set of general principles for guiding the further development of a regional biosolids composting facility;(b)recommendations concerning the legal structure for public ownership of such a facility; and (c) a draft interlocal agreement related to the foregoing. The facility size currently under discussion is one handling 20 dry tons per day of biosolids. This amounts to 111 tons per day of biosolids at 18%solids. For each of these 111 tons of biosolids,a little over half a ton of new bulking agent would be needed in the compost mix. The bulking agent should be primarily yard waste,but it could also include clean construction wood waste,and up to a third of the bulking agent could be mixed paper waste. Furthermore, once a facility was operational, food waste could also be composted in the facility, although, as with biosolids, a little over half a ton of bulking agent would have to be added for each ton of food waste. In the financial analysis of such a facility, a tip fee of$15 per ton was assumed for the bulking agent, although the biosolids would have a significantly higher tip fee. Once a facility was built, on the other hand, the marginal cost of processing a ton of food waste would be such that it is conceivable that food waste could also be accepted at a tip fee as low as $15. OWASA, the Town of Cary,and others continue to discuss the legal issues described above,and they welcome formal participation in these discussions on the part of the Landfill Owners Group. The assistance provided to date by Mr. Blair Pollock has been very valuable and appreciated. � G to r" G v to V2 - a . C M► Mt N O � 40 o to ,a a c °ryo4� mr ° a w e w W WN i �?
