SOLID WASTE MANAGEMENT PRACTICES 32 Attachment A 36 1 0 ' p Among other recommendations, PMA advised the Conservancy that the Island enter into cooperative discussions with the Town of Southold regarding the Town's compost project development activities. This Report This report was prepared at the direction of the Fishers Island Conservancy, and documents further analysis of solid waste management issues for the Island, including the following: 1. Examination of documentation with respect to the Southold composting project, including contractual provisions and estimated economics, to the extent available. 2. Identification and review of all logically available Long Island based solid waste management options potentially available to the Town of Southold. 3. Analysis of information provided by the Town regarding the tax contribution of Fishers Island to the Town and the dollar level of service the Island receives in return. 4 Review of on -Island management practices with respect to bulky waste and metals. Fd Opportunities available to the Town to reduce the impact upon the tax base appear to be the following: 1. To charge a user fee for the disposal of MSW, as the Town currently does for brush and demolition wastes. 2. To "sell" excess processing capability to other municipalities, to the extent it is available. .(Note: the RFP requested a facility sizing matching the flow of MSW to the Town's Landfill. Company proposals may ultimately offer additional capacity. 3. To maximize revenue received from recovered materials. Following the availability of proposals for the finalists, or for the selected company, and the release of an Agreement it will be possible to comment further on the economic, business and technical materials contained therein. Other Long Island Options A review of solid waste management activities other than those of the Town of Southold was performed in early 1989, in order to identify alternatives available to Fishers Island or the Town, in the event Southold did.not implement its composting project: No alternative appears readily available for the Town to participate in the near future. The Towns of Brookhaven and Islip appear to be potential partners to Southold, for j.oint development of a waste disposal facility in the future to serve a multi -town region. Since no specific options were discovered, PMA can only 4 scrap auto.dealers permitted to serve the Island, for the routine disposal of those materials, even for those times when the "value" of scrap results in payment of fee for disposal of the material. 2. For white goods, responsibility should be delegated to an individual for the continuous, as received, preparation of these items for recycling (removal of capacitors, refrigerator doors, etc.), and for their separate storage for ease of retrieval. Further, it is recommended that long term arrangements (e.g. a contract) for the regular removal and disposition of those materials be entered into. 3. For other, non-ferrous metals (aluminum, copper, etc.) separate storage areas, or containers should be placed at the,site, and arrangements be made for their routine removal as well. Implementation of the above program will require education of the citizens and businesses that use the facilities, and allocation of personnel assigned with the responsibility to monitor compliance. Brush Chipper In the event the Island wishes to implement utilization of a brush chipper, consideration should be given to purchase of a unit equivalent to the Eeeger Beever unit, as discussed in Section 6. The initial cost for the unit is approximately $15,000, with the annual operation and maintenance costs reported to be approximately $1,500. 6 i Proposals were to be submitted by September 20, 1988. Mr. Murphy supplied PMA with a copy of the RFP, and reported that at that time the following three companies were finalists, based on the proposals received: -Bedminster Bioconversion Corp. -Reidel Environmental Services, Inc. -Daneco The Proposed Project In summer, 1989 the Town released the information contained in Attachment A. The reader is referred to that document for available information regarding the Daneco Project which the Town is now pursuing. Since the degree of detail is somewhat limited, the nature of PMA's review constitutes an initial const eration of the project information, rather than a comprehensive analysis. Nonetheless, PMA has identified certain questions and concerns about the Project information supplied, as discussed below. a. Annual Waste Processing Capacity The information identifies the design capacity of the facility at 120 tons per day, with a design "surge" of 158 tons per day (3 day duration, we believe is intended). While the design capacity is important, it is critical to evaluate i the effective, annual waste processing capacity.of the facility and to base projected economics on that quantity of waste reasonably expected to be processed resulting from: i) average daily amounts of waste to be processed after taking into account downtime for maintenance, both N V.)- It is not clear from the presentation whether additional property would be needed to implement the facility, and whether any such costs have been included. If additional property must be purchased, the above costs may need to be revised upwards. vi.) It is not clear whether the contractor would be paying, as part of its O&M fee, all insurance, utilities costs, costs of transportation of residues and compost products, and comparable items, or whether allowances for those potential "pass-through" costs were included in projections of annual costs. vii.) The process description calls for brush to be shredded prior to its introduction into the facility. It is not clear that all annual costs associated with this activity are included. C. Proposed System Process Description Since no information was supplied regarding the history of experience of the proposed contractor with the specific process to be employed,, equipment specifications included, it is not possible to comment on the feasibility of the proposed system. In general, the technologies proposed represent - proven equipment components (shredders, trommels, etc.), and as such it is expected that if properly designed and operated, the proposed process is technically feasible. This statement --------- does not represent an endorsement of the technology ^nor of the I made regarding projected recovery rates and c process efficiency; neither of which can be effectively evaluated with the _l.imi.ted n-forma-ti.on-.av-ail1 able. 11 r ' � technologies offered, and -the stated -,experience the selected proposer possesses. In general, composting of municipal solid waste has been more common in Europe than the U.S.. As a result, PMA speculates that the majority of proposers will be offering specialized equipment which has been proven overseas, but not yet here. Although many communities in the U.S. are presently considering implementation of MSW composting projects, few, examples of operating facilities in this country exist. A review of the specific technology, and the experience offered by the proposer cannot be undertaken until the selection is made, and the proposal data is available. Contractual Provisions A proposed agreement to be executed between the Town and the successful contractor was unavailable for review. However, the RFP did contain information regarding the Town's desired contractual position. To the extent the proposers, and the selected vendor in particular, has agreed to accept the Town's stated position, then one would expect that the risk posture for the Town will be as presented in Exhibit 1, which is excerpted directly from the Town's RFP. Schedule Mr. Murphy reported the Town anticipated selecting a contractor by the beginning of February, 1989. Following completion of contract negotiations, receipt of permits from the DEC as required, and completion of financing for the facility, Mr. Murphy's expectation at the time of the meeting was that approximately 12 months will be required to construct the facility and begin operations. 13 ,EXHIBIT 1 (Continued) FOLLOWING ACCEPTANCE Private Public - Facility Public - Terminable 20 -Year 20 -Year After Risk Service Service One Year Failure to meet environmental quality requirements P P P Failure to market compost P P P Failure to meet waste processing guarantee P P P Uncontrollable circumstances: - capital costs P T T - operating cost increases P P P - temporary shutdown P T T• - permanent shutdown P T T Key: P = Proposer - T = Town 0* Regulatory Issues In order to develop a better understanding of.the regulatory environment under which the Town's composting program would potentially be implemented, discussions were held with representatives of the USEPA. As a result of those discussions, three separate regulatory areas were identified that could have impact on the Town project, in the opinion of EPA staff. Federal regulations identified that would potentially affect the project, each deal specifically with the expectation that sludge would be introduced with MSW, into the process system are: 1. Section 257 regulations, which were promulgated in 1979 provide direction to the design and -operation of the facility (including stockpiling of compost product at the facility), and also would regulate land application where the land is being used for agricultural purposes, in the (human) "food chain". 2. Section 503 regulations (which primarily address sludge disposal) are now issued in Draft form and do not presently cover material resulting from co -composting of sludge and MSW. Further, EPA staff confess that in developing the Draft, they did not consider the potential for co -composting. However, even though the regulations to be adopted soon would not address co -composting activities, it is important to recognize that the current effort represents only Round I of a two-phase mandate. Round II, which is reported to be approximately two years away, may address co -composting, acc ro di.ngof the staff 17 SECTION 4 OTHER LONG ISLAND OPTIONS PMA has sought to identify Long Island based solid waste management options that may be available to Southold in the event it does not proceed with the composting, or a different Town sponsored, project. Contact was made with representatives of the following Towns: -Riverhead -Brookhaven -Smithtown -Islip . The following summarizes the information provided: Riverhead Information regarding the Town of Riverhead's solid waste management program was obtained from Ms. Denise Civiletti, a member of the Town Board of Supervisors, and Chairperson of its Solid Waste Management Committee. It was reported that Riverhead, together with the Towns of South Hampton and Brookhaven had historically considered implementation of a waste -to -energy facility to meet the disposal needs for all three Towns. Although Brookhaven continues to promote a waste -to -energy facility, neither South Hampton nor Riverhead anticipate doing the same'at this time. 19 excluded private ownership or operation for the facility itself. Regarding schedule, the Town anticipates initiating project procurement activities in late 1989. Smithtown Discussions were held with the Town Engineer, Mr. Mooney. Smithtown is currently evaluating its solid waste management options, and anticipates selecting an option for implementation in the near future. The two options under consideration at this time include development of a new waste -to -energy facility (at an identified site previously used for solid waste management), or to contract for disposal services with the private company that will build a waste -to -energy facility in the Town of Huntington. The contractor for the Huntington project, Combustion Engineering, has expressed a desire to add an additional processing train to the facility, and.to provide Smithtown waste disposal services through the disposal capacity derived therefrom. Smithtown has identified several benefits from participation in the Huntington program, which include a shorter lead time for implementation and the avoidance of potential neighborhood objections that may result from an attempt to site a new facility. 21 SECTION 5 TAX BENEFIT/BURDEN In an effort to identify the tax contribution Fishers Island, as a discrete geographic entity, makes to the Town of Southold, and in particular the Island's share of the Refuse and Garbage portion of the Town budget, representatives of PMA met with John Cushman of the Town's Accounting & Finance Department. Mr. Cushman supplied the following documents, which have been relied upon in undertaking this analysis: 1. Town of Southold Budget for 1989 2. Budget summaries for the Town of Southold for 1988 & 1989 3. Fishers Island Garbage & Refuse District Budgets for 1988 & 1989 4. Status of Outstanding Indebtedness for the Town of Southold as of December 31, 1987 Mr. Cushman advised PMA that in order to estimate Fishers Island's tax contribution to the Town, the appropriate assessed valuation would be that applicable to the Fishers Island School District. This valuation differs only slightly from that used for purposes of the Fishers Island Fire, Ferry and Garbage & Refuse Districts and is reportedly the more current. The assessed valuation data for 1988 and 1989 is summarized below. 23 TABLE 2 SUMMARY -NONBENEFICIAL BUDGET CATEGORIES STOP A8510.4 21,426 31,376 TOTAL $ 763,558 $499,994 (1) Appropriation as it appears in 1989 Town Budget less direct revenues and fees.

Those who would argue the above Table 2 overstates the nonbeneficial portion of the budget might point out the use of the Town landfill on the Island, by Island residents and businesses, for bulky and demolition waste disposal. It is PMA's understanding the cost for that operation is included in the Town's highway budget; however, its use by Island residents is without cost, while the Town imposes a user fee at the Cutchogue Landfill for the disposal of those same materials. Therefore, Island residents enjoy free services for this activity, supported in part by other Town taxpayers, while at the same time non -Island residents pay separately for the disposal of those same items. The debate over the tax benefit/burden of any particular segment of a community cannot be resolved with certainty, however, PMA has, to the degree possible, sought to isolate those budget items upon which it believes there is general agreement the Island receives negligible benefit. It is PMA's understanding that little, if any, Town control of animals is performed on the Island. Similarly, with respect to the STOP Program (a household hazardous waste collection program) no Town efforts are performed on the Island. Since the Island has no Town Parks or Beaches, these budget categories are not deemed to benefit the tax payers of the Island, either directly or indirectly. Finally, since the Island disposes of its own refuse through the efforts of the FIG&RD, the Refuse & Garbage category is not of direct benefit to 'the Island. By eliminating these -budget categories from the Town's General Fund Townwide (since they are included in that budget) PMA can create a budget which, in all respects benefits the 29 TABLE 6 ESTIMATED FISHERS ISLAND TAX BURDEN IN EXCESS OF BENEFIT GENERAL FUND TOUNNIDE (1) TONNNIDE VALUATION (2) MILL RATE (3) BUDGET (4) ITEMS DEEMED NOT BENEFITING FISHERS ISLAND (5) ADJUSTED "BENEFIT" BUDGET 03 MINUS #4).

At the time representatives of PMA visited the site, in mid-January, only two rusting auto bodies were visible, along with a few appliances. Discussion with the Town employee who supervises the site, a member of the Town Highway Department, revealed the current operating plan and the immediate plans for sequence of filling. The primary storage area for scrap vehicles is currently at the Island's airport, where approximately ten vehicles were awaiting disposal. Management of metals of all types on the Island can be accomplished through reliance upon the Town parcel, and the airport vehicle storage area. However, to improve the level of recovery, it is suggested that the following practices be implemented: 1. For automobiles, responsibility should be delegated to an individual for preparing vehicles for disposal (removal of batteries, gas tanks). Long term arrangements should be sought with scrap auto dealers permitted to serve the Island, for the routine disposal of those materials, even in the event the "value" of scrap results in payment of fee on a regular, or infrequent basis. 2. For white goods, responsibility should be delegated to an individual for the continuous, as received, preparation of these materials for recycling (removal.of capacitors, refrigerator doors, etc.), and for their separate storage for 33 The estimated cost of the unit, including the recommended diesel engine is $15,000. Annual operation and maintenance costs are estimated to be approximately $1,500. 35 FRANCIS J. MURPHY?' r SUPERVISOR t. �'+ TOWN HALL, 53095 MAIN ROAD P.O.

Jort(n Commissioner The Honorable rrancis J. Murphy Supervisor - Town of Southold Town Hall, Main Road Southold, NY 11971 Re: Solid Haste Management Issues Dear Supervisor Murphy: As you know, Governor Mario Cuomo signed the Long Island Landfill Bill (6800-A) into law on June 21, 1983. The purpose of the legislation is to phase out the landfilling of raw municipal refuse as the primary solid waste disposal practice in Nassau and Suf.Olk Counties, and to have recycling programs and resource recovery facilities replace the landfilling of raw municipal refuse no later than December 18, 1990, Resource recovery facilities have been defined to mean either a waste -to -energy incineration plant or equivalently a municipal solid waste composting facility. Hence, the State legislature in 1983 gave the Towns seven (7) years to eli-iinate landfilling as their prime solid waste disposal strategy. Some towns, like Southold, are making progress toward devising and implementing plans relating to solid waste disposal with the intent of closing their landfills prior to December 18, 1990. It is imperative, however, that the progress Southold Town has demonstrated to date be continued to insure a resource recovery (compost -in is operational on December 18, 1990; any delays may result sinmthe Town's non-compliance with the Long Island Landfill Law.. Please be advised that this Department intends to Vigorously enforce the Long Island Landfill Law, Failure to cease they landfilling of raw municipal solid waste on December 18, 1990 will restilt in initiation of enforcement action against the Town. This may lead to imposition of substantial fines and ar. im=mediate landfill closure order, Placing the Town in the Position of off -Island hauling of waste.

The two feeding system 8 and 10 can be possibly used for feeding other streams of materials such as, but not limited to: . ` - Agricultural waste; - Compost having a maximum particle size larger than 10 millimeters (0.39 inch); and - Screen oversize residues to be recirculated. The mixed compostable material is transferred into the building reserved for the accelerated composting using a belt conveyor. The formed pile is about seven feet in height. Two aeration units (12), each one including centrifugal blower and dampers, provide an air flow through the pile via the perforated air distribution channels in the concrete floor. Air is alternatively supplied under negative and positive pressure according the preprogrammed cycle. During the negative pressure phases, the air from the compost pile is discharged through a compost bio -filter in order to control odors. After a two-week duration, a front loader is used to turn the pile; after a subsequent two-week period, the compost from the accelerated composting area is ready to be transferred to the curing area. Depending on the operational requirements, the material can be turned several times. The entire area for accelerated composting is roofed and provided with a water spraying system (13) installed under the roof of the building. The purpose of this system is to control the moisture content of the compost. Before being cured, the compost can possibly be shredded and screened by wing the following equipment of the compost screening section: - Compost feeding system (14); - Compost shredder (15); and - Tertiary trommel screen (16) . The final screening of the compost is done before the delivery of the compost product to the users. 1-2 a TABLE 1 RFP WASTE STREAM CHARACTERIZATION (1) Component Agricultural Brush Garbage (Household) Leaves/Grass Paper Rubbish Sludge (2) TOTAL Percent (Wet Weight) 3.75 15.09 58.68 8.41 0.62 11.50 1.95 100.00 (1) See Table 2.1.1 of Daneco proposal (Page 10) (2) At 30o solids content TABLE 3 REFERENCE COMPOSITION OF THE ENTIRE WASTE STREAM Component Percent (Wet Weight) I.
