-DRAFT - September 17, 1999 Jean W. Cochran, Supervisor Town of Southold Town Hall 53095 Main Road P.O. Box 1179 Southold,NY 11971 Re: Southold Landfill Closure D&B No. 1314 Dear Supervisor Cochran: During preparation of the construction drawings and specifications for closure of the landfill, a number of activities were performed in support of reducing the cost of construction, mitigating potential problems which may occur during construction, alleviating flooding problems in the area of the scale house, and upgrading and replacement of facilities that were not related to design of the cap. These activities included the following: 1. Sampling and testing of glass sand at the landfill as required by NYSDEC (cost: $7,200) 2. Continuing services in connection with securing and evaluating alternate materials for filling the former scavenger waste lagoons and contour grading material for cap construction (cost: $4,000) 3. Evaluation of existing soil cover thickness to determine the need for additional daily soil cover and odor control measures during regrading of the landfill (cost: $6,600) 4. Relocating and reconstruction of the Fire Department siren and nonpotable water supply well (cost: $6,400) 5. Design of a storm water management system to mitigate flooding in the area of the scale house and provide for adequate drainage for the area of the planned Collection Center improvements (cost: $4,400) A detailed description of each of these activities is provided in the attachment to this letter. While the total cost of these additional services is $28,600, the Town (and Cutchogue Fire Department)has received the following benefits: Jean W. Cochran, Supervisor Page Two Town of Southold September 17, 1999 1. The anticipated value of the glass sand, assuming continued receipt of the sand up until commencement of construction, is $190,000 as an avoided cost. 2. The estimated value of wood waste from George's transfer station is $75,000 as revenue and avoided cost. 3. The estimated value of dredge material from the Town of Huntington is $56,000 as an avoided cost. 4. Sufficient cover soil appears to exist in the area of planned regrading which will not require additional soil to be provided by the Contractor as daily cover, which will reduce construction cost, and odor control requirements have been incorporated into the construction specifications. 5. The Fire Department siren will still be located at the landfill. 6. Water supply will be available during construction of the cap which will reduce closure costs if the contractor would need to obtain water off-site. In addition, an adequate water supply will be available for yard waste composting, maintenance of site facilities and fire fighting, including a supplemental source of water for the Fire Department in the vicinity of the landfill. 7. Current drainage problems will be alleviated at the scale house and increased drainage problems will be mitigated as a result of planned expansion and upgrade of the Collection Center(assuming that storm water runoff from the North Road can be corrected). In addition to the above, we recommend prequalification testing of the stockpiled golf course sand in accordance with the NYSDEC construction quality assurance requirements. This will ensure that all of the material meets specifications to avoid potential change orders. Although the cost of this testing is $17,900,this cost would be incurred by the construction contractor and be part of his bid price.

September 9, 1999 REVISION 3 RE: PN 199-604 PROPOSAL TO PROVIDE LABORATORY TESTING SERVICES SOUTHOLD LANDFILL TOWN OF SOUTHOLD, NEW YORK Dear Mr. Glass: In accordance with our telephone conversation on August 24, 1999, we are pleased to submit this proposal to provide laboratory testing services during the closure of the Southold Landfill in the Town of Southold, New York. It is our understanding that our services will include laboratory testing of the stockpiled sand venting layer material and field services including stockpile sampling and delivery to Tectonic's laboratory. Based on our conversation, the existing stockpile is approximately 115,000 cubic yards and consists of a granular sand material. It is our understanding the required laboratory testing includes the following: • Sieve Analysis (ASTM D422) • Standard Maximum Dry Density/Optimum Moisture Determination (ASTM D698) • Constant Head Permeability (ASTM D2434) It is further our understanding that the required frequency of testing is one sieve analysis per 1,000 cubic yards, one permeability test per 5,000 cubic yards, and maximum density testing as appropriate. Based on these guidelines, the total number of laboratory tests will be approximately 115 sieve analyses, 23 permeability tests, and 6 maximum density determinations. As noted above, part of our services also includes providing field sampling from the sand venting layer stockpile and delivery of the soil samples to the laboratory for testing. It is our understanding that the excavation equipment required for the sampling will be provided by others. Based on our discussions relative to the dimensions of the • TECTONIC Mr. David Glass, P.E. Page 2 September 9, 1999 stockpiles, the equipment should be capable of excavating to a depth of approximately 25 feet or more. As discussed with you, the sampling will likely entail random excavations within the stockpile to obtain representative soil samples for conformance testing. For estimating purposes, we have assumed that the stockpile sampling will have a duration of two weeks at 10 hours per day (two hours of overtime/day). As requested, our services will be provided for a not-to-exceed fee based on the following assumptions. • The stockpile sampling will have a duration of two weeks at 10 hours per day for a total field inspection time of 100 manhours. If the stockpile sampling duration exceeds the two week duration, we will not continue until authorized. • The laboratory testing assumes 115 sieve analyses, 23 permeability tests, and 6 maximum density determinations. • The results of the laboratory tests will be provided upon completion in one test result submittal. As requested, no engineering analysis or report preparation is included in our scope of services beyond the submittal of the test results. If engineering services are requested to evaluate the soil samples for compliance, we will be pleased to provide such services for an additional fee. • Included with the test results submittal will be a location plan indicating the approximate sample locations within the stockpiles. As discussed, base map(s) on AutoCad Version 14 of the stockpiles, indicating the dimensions, locations, and topography, will be provided by your office for our use in selection of the sampling locations and preparation of the location plan. The total not-to-exceed fee for field sampling and laboratory testing based on the above assumptions and unit rates provided below is estimated to be $16,850.00. A breakdown of our not-to-exceed fee is as follows: Field Sampling_and Delivery Services (Assumes 2 week duration) Engineering Technician 80 hours @ $32.00/hr. $ 2,560.00 20 hours @ $48.00/hr.

Gla ate 1. a 'San 1. As required by NYSDEC, four samples were collected from the stockpile of glass sand near the former lagoon. A portion of one of the -four samples was tested For volatile organic compounds(VOCs). The remainder of the sample and the other three samples were composited and tested for semivolatile organic compounds, PCBs, pesticides,herbicides, metals and cyanide. 2. As required by NYSDEC, two additional samples were collected from a second pile of stockpiled glass sand located now the high voltage electric line tower on the landfill. The samples-were composited and analyzed for metals. 3. The results of the analyses were evaluated and presented in a .letter report to NYSDEC dated May 26, 1999. As a result of the testing and report, NYSDEC has allowed continued use of glass sand as part of landfill closure. 4. As required,by NYSDEC, a sampling protocol was prepared for sampling and analysis of glass sand stockpiled at the landfill in order to allow continued acceptance of glass sand at the landfill. Seeg ng and&gig ting Alternate-Fill and Contour Grading Material As part of continuing efforts to secure alternate fill and contour grading materials to reduce the cost of landfill closure, D&B has been requested to review a number of chemical and geotechnical data packages and additional information as follows: 1. OnLine Management Associate`, Inc. of Commack, New York provided chemical data on soil and car shredder screenings. (Upon review of the data, it was recommended to the Town that the material not be accepted at the landfill.) 2. Terry Contracting and Materials, Inc. provided chemical and geotechnical data regarding shredded wood waste stockpiled at a site known as "Goorge•s" in Southampton. In addition, D&B conducted a site visit to visually inspect the _ stockpiled materials at George's, prepared a letter to the Town providing an evaluation of the data and recommending acceptance of the wood waste, and reviewed and commented on a draft agreement for acceptance of tha material at the landfill. . 3. The Town of Huntington provided chemical 'data and a plan for obtaining geotechnical data .for material to be dredged from the Hecksher Park pond in the o u iuro9i�oi 1 O- THOLD T01411 HALL 516 765 1823=94 P. 1AG$ Ce 32 Village of Huntington. (Upon review of the data to date, it appears that this material is acceptable for use at the landfill--pending receipt of additional data requested.from the Town of Huntington) The total cost of the effort identified above.for glass sand sampling and evaluation of alternate materials, including labor, expensesand analytical laboratory services is $7,200. In addition to this amount,we suggest the addition of $4,000, for a total of$11,200, to continue to pursue and evaluate alternate sources of material to reduce the Town's cost for closure of the landfill. For informational purposes,it is estimated that to date approximately 12,000 cubic yards of glass sand have been used at the landfill to fill in the former lagoon, It is anticipated that an additional 15,000 cubic yards of glass sand will.be delivered to the landfill before closure construction begins (on or around April 2000). The estimated cost for general fill is $7 per cubic yard. Therefore, the projected avoided cost that the Town will realize as a result of the glass sand is estimated to be$190,000. The estimated volume of wood waste to be delivered to the landfill from Osorge's transfer station is 5,000 cubic yards. This material will be delivered by Terry Contracting and Materials, Inc. for $8 cubic yard to be paid to the Town. Taking Into consideration the avoided cost for general till, it is estimated that the projected combined revenue and avoided cost that the Town will realize as a result of the wood waste is$75,000. The estimated volume of dredged material from the Hecksher Park pond to be delivered to the landfill is 8.000 cubic yards. Therefore, the estimated value of this material (resulting from avoided cost)to the Town is$56,000, jai gigInvestigglon The final subgrade contours for the landfill have been completed.. This design information in conjunctiop with the updated topographic information showing existing surface elevations has beer:'utilized to identify area where cutting and filling will be required to obtain the design subgrade. As a result,the following work has been perforated: 1. In certain locations across the landfill surface,cutting to a depth of up to 6 feet will be required. A test pit program has been conducted in these areas to determine the general depth of existing cover material and whether special odor control measures are required, is particular near residences, This effort will in part provide the information required to avoid the purchasing of fill material for daily cover during regrading. 2. In the area where extensive cutting will be required to construct the .northwest recharge basin, a test trench has,been constructed to determine the depth of bulky waste. This information will be used to develop quantity estimates and determine what portion of the material can be used as fill to,obtain anal contours on other parts of the 1=011. o a 14fMJ Mi 2 OCT-l1 �07 %g�` 0�;091�-P1&ITHOLD TObU1 HALL 515 765 1823 C P a02 5/12 3. Installation of a stilling basin for storm water drainage is required along the southwest perimeter of the landfill. Test pits have*been constructed at this location to determine the depth of waste in this area to determine the need to install a geomembrane beneath the basin, and to develop quantity estimates and confirm whether or not the material c>tari be used as fill to obtain final contours on other parts of the landfill. 4. A memorandum was prepared documenting the results of the design investigation. The investigation has provided information which will be used to preclude problems during construction which would otherwise represent the potential for change orders. S. The drawings and specifications were modified to include management of bulky waste which was oneountered during the investigation and will need.to be disposed off-site. The total cost of the effort identified above for the design investigation is $6,600. Although there will be potential cost savings to the Town resulting from the design investigation, a figure cannot be estimated based on available information. Ralocs n o Fin D part ,ent Siren and Winer ner Sunni,►Well As part of the original landfill closure design effort it was assumed that the existing Fire Department siren and water supply well on the landfill would be abandoned and not replaced on the landfill site. The Town has decided, however, as part of closure, the Fire Department siren and water supply well.will be replaced at new locations on the landfill property. The effort required to include this work as part of the construction drawings and specifications includes the following:, 1. Review of data and information provided by the Town with respect to the details of construction of the existing water supply well, 2. Selection of a site,for the new water supply well and obtaining approval of Cutchogue Fire Department for the new siren. 3. Preparation of drawings and specifications for the new well, including new electrical service, meter, 25-hp submersible pump and appurtenances, stone pad and bollards to protect the well. 4. Preparation of drawings and specifications for the now siren, including new electrical service,meter and appurtenances. S.

Preparation of drawings and sPecifications for a new low watt light i0d a manually operated 500-watt floodlight as requested by the Fire Department to provide lighting at the water supply well site. The total cost of the effort identified above for relocation of the fire department well and water supply well is 56,400. Although a cost savings to the Town cannot be defined, without a replacement water supply well at the landfill site, the Contractor will be required to obtain construction water off-site at an additional cost to the project. In addition, a supply of the water at the site for fire fighting purposes and irrigation would not be available. The original closure design effort includes management of all stores, water runoff from the final landfill cap. Howsver, because of current flooding problems in the area of the scale house and anticipated exacerbation of these problems resulting from .planned Collection Center improvements, the Town requested that D&B assist in alleviating the flooding problems as part of the closure design effort. The additional effort for management of the scale house and Collection Center storm water runoff-includes the following: 1. Review of current storm water problems in the area of the scale house and along the southwestern property line at the entrance to the landfill. 2. Estimating the quantities of storm water generated from the western side of the Collection Center (Aria D-5 on the Construction Drawings), including the existing scale house, an area of approximately 5.5 acres- 3.

Preparation of drawings and specifications for construction of drainage structures, including a manhole and corrugated HDPE pipe to provide the connection. 5. - provision of recommendations to the Town that a drainage system be installed along the southwestern side of Area D-5 to help alleviate ponding of storm water and provide controlled discharge to the proposed drainage sem, and a recommendation that the Town pursue additional storm water.controls needed to redirect flow from Suffolk County Road 48 (North Road) away from the entrance to the landfill site In order not to exceed the capacity of the planned landfill storm water collection system, it should be noted that Ibis on-site drainage management ef'f'ort will not mitigate the problem of storm water runoff from County Road 49 draining onto the landfill property. The total cost of the effort identified above for management and design of the drainage from the scale houso area and Collection Center is$4,400. 0 1314/r0917901 4 QC Ssdllpocl, ',�� OT MOM *HOLD TOWN HALL 516 765 1823'0' • P a0z 7/12 PregaallticaH n Testini Qnsite_.oi15{tocko�iles In order to "prequalify" the Town's:existing on-site stockpiles of sand jo be used in the construction of the Oas Venting Gayer, the Barrier Protection Layer and the Fabricated Topsoil Layer of the cap system in order to satisfy NYBDEC's quality assurance/quality control requirements, the sand must be sampled and tested according to the methods and frequency contained in the design specifications. Based on estimates provided by- the. Town, the existing on-site stockpiles are. a total of approximately 115,000 cubic yards of granular sand. The required laboratory testing comprises the following; • Sieve Analysis(ASTM D422) • Standard Maximum Dry Density/Optimum Moisture Determination(ASTM D698) • Constant Head Pemeability(ASTM 02434) The required frequency of testing is one sieve analysis per 1,000 cubic yards, one permeability test per 5,000 cubic yards and maximum density testing as appropriate. Based on these guidelines, the total number of laboratory tests will be approximately 11 S sieve analyses, 23 permeability tests and 6 maximum density determinations. The sampling will entail random excavations within.the stockpile to obtain representative soil samples -for conformance testing.. For 'estimation purposes, it is assumed, that the stockpile sampling will have a duration of 10 days at 10 hours per day. Services during the stockpile sampling will include. obtaining representative soil samples and delivery to the laboratory for testing. The cost for sample collection and analysis (including expenses) by Tectonic Engineering is attached. It is assumed that the Town will provide and operate the excavation equipment for the sampling. (A backhoe with a reach of 25 fent and a front-end loader will be ' required.) The total cost of the effort identified above for the testing of on-site soil stockpiles is $17,900; however, this would be the same cost if the construction contractor was required to test this soil. (This includes $16,800 for sampling, testing and reporting as'indicated on the attached proposal from Tectonic and 51,100 for supervision and documentation by D&B..) Therefore, this testing will not result in additional cost to the Town for landfill closure.

Town Attorney Town of Southold Town Hall 59095 Main Road Southold,NY 11971 Re: Southold Landfill Closure General Construction D&B No. 1314 Dear r a oski: As your are aware, Dvirka and Bartilucci Consulting Engineers (D&B) has begun preparation of the Construction Contract Documents for the capping and closure of the Southold Landfill. The purpose of this letter is to outline some of the requirements of the contract documents that we need to discuss early in the document preparation process. Legal Requirements Construction and Work Easements: One of the items needed for inclusion in the construction contract documents is "construction and work easements" on the north, south, east and west sides of the site. These easements are needed because the cap and limits of the waste abut the property lines of adjacent property owners. It is our experience that a minimum 40-foot easement is generally required in order to simplify construction and minimize the cost to the Town. There is one exception to the 40-foot requirement and that is on the south side of the site parallel to the property now owned or formerly owned by Arnold W. and Rolland Wilson and the First Baptist Church of Cutchogue. At that location we believe a 10-foot easement will be sufficient. The enclosed drawing shows the easements needed and the information we have on the property owners who will need to be contacted. Please advise as to how the Town will proceed on, obtaining these easements. Public Bidding: It is our understanding that the project will be publicly bid in conformance with applicable public bidding laws. We plan to prepare the contract documents so that the entire scope of work is awarded to the lowest responsible and responsive bidder. Please verify whether award of the contract to a single prime contractor complies with the Wick's law. A DIVISION OF WILLIAM F.COSULICH ASSOCIATES,P.C. OVIRKA AND BARTI•CI • Gregory Yakaboski, Esq. Page 2 Town Attorney Town of Southold Town Hall May 14, 1999 Affirmative Action: We have not included requirements for subcontracting portions of the work to Local, Minority, Women-Owned, Disadvantaged Business Enterprises or other groups. Please verify whether any set-aside or other special programs apply to this contract. This information should be included in the agreement between the Town and the New York State Department of Environmental Conservation(NYSDEC) for Title 5 reimbursement. Bonds and Insurance: We will also send you a letter requesting instructions for bond and insurance requirements in a separate package. The bond and insurance package will contain several standard forms, including the standard general conditions. Please review the bond and insurance requirements of the standard general conditions. Project Labor Agreements: Please advise us whether this project is subject to a Project Labor Agreement, or any other legal requirements you are aware of that this letter does not address. Use of Standard Forms We plan to prepare the contract documents by customizing an integrated set of standard forms that we have developed for publicly bid municipal works. Please provide us with copies of any special forms that you wish to include in the contract documerift- at_ are required under applicable laws or regulations or Town of Southold practice. Important Contract Terms Selected important contract terms are highlighted in the following paragraphs. Pre-Bid Meeting: The Advertisement for Bids contains provisions for a pre-bid meeting. It is our understanding that a public owner may not reject a bid because a bidder failed to attend a pre-bid meeting. Nevertheless, we have found that pre-bid meetings (and subsequent minutes of the meetings) provide a useful format to address contractor concerns and many of our clients require them. Notice to Proceed: The contract documents measure time for substantial completion of the work from the date given on the Notice to Proceed. If you do not issue a Notice to Proceed, the contract time will not begin to run, and the contractor will not be under a time constraint to achieve substantial completion. Subcontracting: The Supplementary Conditions will fix the percentage of the total contract price that may be subcontracted out without Town of Southold written permission. On similar projects, we have found that subcontracting no more than 60 percent of the total contract price generally . OVIRKA AND BAATILUCCI Gregory Yakaboski, Esq. Page 3 Town Attorney Town of Southold Town Hall May 14, 1999 encourages qualified contractors to bid on the work while reducing the possibility that the contract will be "factored out" to third parties with little accountability for the quality of the work. This needs to be checked with your agreement with NYSDEC to be sure that they do not have a different minimum percentage. Separate Contractors: The "Work by Others" sections of the general condition makes each contractor responsible for coordinating its work with that of other contractors at the site. It limits the owner's liability for a contractor's failure to coordinate, and permits contractors to sue each other directly for damages caused by a failure to coordinate, if each contract that you enter into contains similar language. Hazardous Environmental Conditions: The risk of encountering unanticipated hazardous environmental conditions is on the owner. The owner is responsible for obtaining environmental permits and either rendering the affected area safe for the contractor to resume work or specifying the conditions under which the contractor may resume work. The contractor continues to be responsible for hazardous conditions that are caused by the contractor's operations. Differing Site Conditions: In its bid and in the agreement, the contractor represents that it has visited the site and is familiar with site conditions, and it has obtained carefully studied all reports and investigations furnished in, or with, the contract_docThe contractor also represents that no additional investigations are required. If the contractor encounters a subsurface or latent physical condition that differs materially from those indicated in the contract documents or generally recognized as inhering in the work, it may be entitled to a change order. Requests for change orders must be in writing and the contractor must comply with contractual notice provisions. No Damages for Dela: The contractor's sole and exclusive remedy for delays beyond the contractor's control is an extension of time equal to the time lost due to the delay. Liquidated Damages: Because of the difficulties and expense associated with proving actual damages due to the contractor's delay, we suggest incorporating liquidated damages provisions into the contract. The standard forms include such provisions. You must decide whether you prefer to seek liquidated damages or actual damages for contractor-caused delays before entering into any contracts. Liquidated damages, if reasonable and not a penalty, are generally enforceable instead of actual damages. With your input, we will develop reasonable amounts for liquidated damages for delays in substantial completion and final completion of the work. Dispute Resolution: The engineer is the initial interpreter of the requirements of the contract documents and claims, disputes and other matters referring to the acceptability of the work are OVIRKA AND BARTILUCCI Gregory Yakaboski, Esq. Page 4 Town Attorney Town of Southold Town Hall May 14, 1999 referred initially to the engineer. However, at present our standard contract documents do not contain a procedure for resolving disputes if the contractor protests the engineer's decision. Please advise us if you have established alternative dispute resolution procedures for contract disputes. Risk Allocation Matrix: The contract documents allocate the risks of certain events to the owner (such as hazardous environmental conditions) or contractor (failure to coordinate work with others). The enclosed risk allocation matrix sets forth various risks and summarizes how they are allocated in the standard forms. Follow-up I will call you in the next few weeks to set up a meeting to discuss this letter. Please feel free to call me at any time with any questions. Very trul yours, Thomas.F,_Maher, P.E.

Box 1179 Southold, NY 11971 Re: Southold Landfill Closure D&B.No. 1314 Dear Supervisor Cochran: The purpose of this letter is to provide a scope of work and budget to perforin testing of the glass sand material being delivered to the landfill by Waste Management. This work will be conducted by our geotechnical subconsultant,Tectonic Engineering. The purpose of the testing is to determine the ,effort required by construction equipment to compact the glass sand to be used for general fill and contour grading material for landfill closure. The equipment used will be that expected during construction, such as bulldozers. The parameters that will be evaluated in the field include lift thickness, density and possibly moisture content if it varies too much from optimum moisture content. The optimum moisture content and maximum dry density have already been determined by the Standard Proetot test method (ASTM D 698). This testing data will be the basis for measurements of dry density, moisture content and percent compaction achieved during the proposed field tests. Therefore, the tuaterial delivered and used for the test must be the same. One grain size sample will be obtained to verify the material is the same. In addition, one Modified proctor (ASOM D 1557) will be performed to provide data on percent compaction relative to the tY►wtnum dry density determined by this method, since it is more representative of the level of effort provided by models construction equipment. The proposed scope of work is as follows: Engineering • Review background data and define field test parameters • Direct field personnel • Review field test results and prepare brief letter report appending field data and summarizing findings A DIVISION OF WILLIAM F.COSULICH ASSOCIATES,P.C. .

Pursuing and securing the use of alternate contour grading material, represents a significant cost benefit for the Town since purchase of thousands of cubic yards of general fill material required for landfill closure Is avoided. Additionally, the development of a compost blend for vegetative growth medium using the Town's yard waste compost will result in avoiding the cost of purchasing topsoil for the landfill cap. A description of the services provided is presented below. Securing alternate contour grading material has included: ,DEC-09-98 15 : 56 FROM: ID: � PACE 7/9 OVIRKA ANO BAATILUCCI Jean W. Cochran, Supervisor Page 3 Town of Southold October 29, 1998 • Obtaining, reviewing and evaluating chemical and geotechnical test results from three potential sources: NY'CDEP Flushing Day Retention Facility Project, Waste Management glass sand, and NYCDEP City Island Subaqueous Force Main Project (Eastchester Bay). • Preparing applications for NY'SDEC approval of the Flushing Bay material, Glass Sand and Eastchester Bay material). Approval has been successfully received for all three materials for the specific use (i.e., contour grading material for closure of the Southold Landfill). • Preparing provisions for agreements between the Town and the material suppliers for the delivery of glass sand and the Eastchester Hay material. An agreement has been reached with Waste Management for delivery of glass sand to the landfill. Developing a compost blend and seed mixture for growth of landfill cover vegetation has included: • Obtaining nutrient analyses (performed by the Cornell Nutrient Analysis Laboratories) for two (2) compost soil blends to determine recommended fertilizer and pH adjustment requirements. • Developing specifications for a seed mixture suitable for growth on the compost blend and as a landfill cover,based on the results of the nutrient analysis. • Preparing a letter providing recommendations to the Town for two (2) test plots to verify the nutrient and seed mixture recommendations. Obtaining seed mixture for the test plot program and providing technical support for implementation of the program. The total cost associated with the additional services required to secure alternate contour grading material and developing an optimal compost blend and seed mixture is approximately $10,000. We suggest the addition of$5,000 for a total of$13 000 for this task in ordeit to continue pursuit of additional sources of material which will reduce the Town's cost for closure of the landfill. As a result of our efforts, if the alternate materials are obtained at no cost to the Town, based on a typical price of $5/cy for general fill, the Town could realize a cost savings of up to $400,000 for contour grading material. and more if topsoil is considered.

Box 1179 Southold, NY 11971 Re: Southold Landfill Closure D&B No. 1314-F Dear Supervisor Cochran: In response to the NYSDEC's comments on the preliminary landfill closure grading plan, in which they requested a minimum 4% surface slope and capping of the former scavenger waste lagoons, the grading plan was revised. The revisions, however, resulted in a substantial increase in the quantities of fill and contour grading material which would be required, on the order of approximately 36,000 yd3 and 26,000 yd3 to fill the former lagoons and achieve a 4% slope on the western portion of the landfill, respectively (for a combined total of approximately► 62,000 yd3 of required fill material). At an estimated unit cost for general fill material of$12/yd (installed)62,000 yd3 equates to approximately $750,000 which is a substantial cost. As a result of this cost, D&B contacted the NYSDEC to determine whether in light of these findings the concepts put forth in the initial grading plan (i.e., 2% slopes and not filling in the lagoons)could be reconsidered. NYSDEC has indicated that this-is a possibility, but that additional information is required to assess this request including further characterization of the former lagootu, and drainage and settling evaluations to support the use of 2% slopes. As a result, we have prepared the following description of suggested activities to obtain the information required by NYSDEC. I. In order to determine whether solid waste has been buried in the former lagoons, test pit excavation is required. We have assumed that the Town will provide the labor and equipment for test pit excavation and D&l3 will provide for ovetsight, visual characterization and logging of test pit excavations. The estimated tirne to complete this work is one(1)day and the cost for D&B's labor and expenses is$900. 2. In order to characterize the approximately 33,000 yd3 of soil which lies been stockpiled at the landfill and evaluate it for future use in connection with closure construction, in particular for suitability with respect to drainage on 2% slopes, geotechnical Analyses are required. D&B will collect up to four(4) samples of the stockpiled material for analysis A DIVISION OF WILLIAM F.COSULICH ASSOCIATES,P.C. DEC-09-98 1 S: S 3 FROM* ID PACE 2/8 CVIAKA ANC 9APTILUCCI Jean Cochran, Supervisor page Two Town of Southold June 10, 1998 for the following parameters: grain size (ASTM D422), constant head permeability (ASTM D2434), modified proctor (ASTM D1557) and direct shear strength (ASTM D3080). The estimated cost for the geotechnical analysis of four (4) samples is $2,840 and the cost for D&B's labor and expenses is$800. 3. In order to perform the settlement analysis requested by NYSDBC to support the use of 2% slopes, a proposal has been obtained from our geotechnical subconsultant, Tectonic Engineering Consultants, which is presented as Attachment A. As indicated, Tectonic's cost to complete the proposed scope of services is$2,000. 4. In addition, as part of this effort, test pit excavation is recommended in the northwest corner of the site since the extent of buried waste has not been completely characterized in this area. The cost for this effort is included in Item 1 above. 5. In order to evaluate the drainage properties of subsurface soils in the area of the former waste lagoons, being considered for use as a possible recharge basin, as well as in the northwest corner of the landfill where construction of a recharge basin Is also being considered, advancement of two(2) soil borings with continuous split spoon sampling from ground surface to the water table is required. Again we have assumed that the Town will provide the labor and equipment for soil boring construction and D&D will provide for oversight and visually characterizing and logging the samples. The estimated time to complete this work is one(1) day and the cost for D&B's labor and expenses is $800. The total cost for this work, including labor, expenses and geotechnical laboratory analyses is $7,200. The results of this work will be incorporated into the Landfill Closure plan. Since the results of this work are necessary to continue preparation of the Closure Plan, we recommend completing it as soon as possible. We are prepared to undertake this work during the week of June 15, 1998 with your approval.

Cochran, Supervisor Town of Southold 53095 Main Road P.O. Box 1179 Southold,NY 11971 Re: Southold Landfill D&B No. 1314 Dear Supervisor Cochran: In preparation of the Closure Plan, we utilized the latest topographic map for the Southold Landfill which was prepared in 1995. Although we do not expect significant settlement of the landfill since 1995, according to Jim Bunchuck some changes in landfill elevation may have taken place since 1995, in particular as a result of placement of construction and demolition debris, and perhaps some regrading. In order to ensure that elevations have not changed significantly, which possibly could affect the grading plan and quantities of material required for grading, it would be prudent to obtain a current topographic map of the landfill. The cost of the map, including a fly-over, aerial photograph and topographic map at a scale of 1 inch=40 feet with 2-foot contours(Aerographics, Inc.) is $4,635. This cost does not include surveying if the previous control elevations need to be resurveyed. It is my suggestion that this topographic map be prepared within the next 30 to 45 days. If you have any questions with regard to this letter, or require additional information, please do not hesitate to call me. Very truly yours, Thomas F. Maher,P.E.

As discussed at the meeting, apparently there was a misunderstanding as to the intent of the grading plan which was prepared for the Town, The intent of this "rough" grading plan was to address the Town's request to determine an estimate of fill that would be required for contour grading material for closure of the landfill. This estimate would provide the Town with information regarding the amount of material that could be accepted at the landfill for the purpose of closure. This rough grading plan also would provide guidance to the Town for shaping the landfill for closure with its own forces, if it decides to undertake this effort. In addition, it provided some concepts for drainage, including drainage to the south and west. l4owever, given the uncertainty of the Town's plans for the Transfer Station and areas along the southwestern boundary of the landfill, we also considered, as a fall-back option, to dispose of drainage water through a subsurface piping system to the borrow area in the northeast corner of the landfill property. Tbe-play--that-vmg prepared- vas-mrintended-to-be-a-€tial-;-de4eiled-grading p d a na8e plar►,,b�t t l!id�•cIasur�,e nEEpt�tc_Obtain,feedba*frotw thLr, mvh. To address Hank Pope's comments, as we discussed, they would be applicable if the intent of our preliminary grading plan was to provide a final grading and drainage plan, which it was not. As 1 discussed with Hank, all of his comments would have been addressed (and will be addressed) in the preparation of the final grading and drainage plans. A DIVISION OF WILLIAM F.COSULICH ASSOCIATES, P C, t c� •� SLoF SQL = i S - ---- - ---- ------ --fl fl OVIAKA AND®ARTIL.US0 Alice Hussie rage Two Town of Southold Town Hall February 2, 1998 Following our meeting, I felt that you were satisfied with the intent of the rough grading plan and that your and Hank's comments were considered and would be addressed. As we also discussed, prior to moving forward, soil borings will need to be constructed in potential areas for recharge basins in the southern and western portions of the site, and the ToNvn will need to decide if the current plan for the expanded Transfer Station will be modified to allow more space for a recharge basin, and if the Town requires any of the other areas of the landfill for equipment and materials storage, parking, etc. As I mentioned following our meeting on the above, we are concerned about the article in the Suffolk Times on January 22, 1998, which, although likely resulting from the misunderstanding of the intent of the rough grading pian, we feel was not correct. With regard to the area for the compost pad, as explained, we developed the size of the pad in discussion with Jim Bunchuck. However, as discussed at our meeting, if the Town requires additional area for composting, the pad easily can be enlarged to five acres, i re qtrl to coi.vnetit�._on drainege,,_as explained above and at oltr_..meeting,..-sur€awdr ' age would be directed to,the,southein.portion of-the an fill ro, of w ' e.drain "`�"--a-r..._--___ ._Pe __hal age-tci.the_north, if necessary, would,lZe ranted through subsurface 'lapin ich would not have "water running uphill" as stated„in the, ar ide, We would preclate tt if there could be a clarification provided to the media that would explain the context in which the statements were made and that.

Temporary off-site monitoring points #36 and #37, near the south-central portion of the site (near the scalehouse) were destroyed since the Landfill Closure Investigation, however, adjacent on-site points 2A and 3 (see Figure 1) did not indicate the presence of methane (0% LEL) on this date. As a result, points #36 and #37 were not reinstalled. Based on these results, off-site migration of methane in this area did not occur at the time of this investigation. 2. Temporary off-site monitoring point #44, near the northwest portion of the site (in the potato fields), was destroyed since the Closure Investigation, and adjacent off-site points #38 through 943 (see Figure 1) indicated the presence of methane at greater than 100% LEL on this date (#45 was saturated and an accurate reading could not be made). Based on these results, off-site migration of methane in this area occurred at the time of this investigation. 3. Temporary off-site monitoring point #46, on the east-central portion of the site, did not indicate any methane (0% LEL), however, adjacent on-site point #15D did indicate the presence of methane at greater than 100% LEL on this date. Based on these results, off- site migration of methane in this area did not occur at the time of this investigation. 4. Temporary off-site monitoring points #47 through #51, near the south-central portion of the site (at Corazinni's Asphalt Co.), were destroyed since the Closure Investigation, and as a result, six points (#47 through #52) in the same general area were reinstalled on December 30 (see Figure 1). Temporary monitoring point #47 was measured at a maximum of 23% LEL and a steady reading of 17% LEL; temporary point 948 (301/o LEL maximum, 7% steady); temporary point #49 (69% LEL maximum 65% steady); temporary point #50 (greater than 100% LEL); temporary point 1#51 (greater than 1001/6 LEL); and temporary point 52 (0% LEL). Based on these results, off-site migration of methane in this area occurred at the time of this investigation. DVIRKA AND BARTILU 1 • Thomas Maher Page Two February 21, 1997 Off-site migration of explosive methane gas was measured in excess of the NYSDEC Part 360 standard of 100% LEL (Part 360-2.17[f](l][ii]) for gases at or beyond the property boundary on December 30, 1996, at two of the four areas previously identified during the Closure Investigation. It should be noted that the methane trench has been almost entirely filled in on the east-central boundary of the site which may be the cause for off-site migration of explosive gas adjacent to temporary monitoring points #15G, 16 and 17. Although the methane trench exists adjacent to temporary monitoring points 11 E, 11 F, 11 G and 12A (and permanent monitoring point 12), the trench contains significant amounts of silt which has reduced the permeability of the trench and therefore its effectiveness to vent explosive gas. As a result of these findings, it is recommended that the methane gas venting trenches be rehabilitated, in particular where off-site measurements of explosive gas were 100%LEL.

Asphalt Pad Based on the planned dimensions of the pad (450' x 1,000') and a 6-inch base of "packed crushed stone or like material," the approximate volume of recycled concrete that could be used by the Town for construction of the base of the pad would be 8,500 cubic yards (cy) or 17,000 cy if the base was increased to 12 inches, which would not be unreasonable. This would equate to approximately 10,000 tons and 20,000 tons, respectively, based on an assumed weight of 2,500 lbs/cy for this type of material. 2. Contour Grading Material For the calculation of the volume of C&D material required for contour grading material, we looked at five different grading contours: two contours with a 4% grade, which is the basic minimum slope required by NYSDEC for landfill closure, and three contours with an 8% slope, which is not unreasonable to allow a factor of safety for settlement (see attached figures). Based on these grading contours, the quantity required for closure varies between a minimum of approximately 160,000 cy and a maximum of 330,000 cy. Based on an assumed weight of 1,500 lbs/cy, these volumes equate to 120,000 tons and 250,000 tons, respectively. A DIVISION OF WILLIAM F.COSULICH ASSOCIATES, P.C.

Regional Solid and Hazardous Waste Engineer NYSDEC Region 1 Building 40 SUNY Stony Brook Stony Brook,NY 11790-2356 Re: Southold Landfill Closure Investigation Work Plan D&B No. 1314 Dear Mr. Cava: As a follow-up to a telephone conversation on March 1, 1996 between Mr. Keith Robins of my office and Mr. Mathew Eapen of your office, we request the following changes in the Southold Landfill Closure Work Plan dated December 1995. These changes pertain to Section 3.2.1 of the work plan: 1. Since a low volume (approximately 10 gallons) of purge water is needed to be evacuated from a shallow well, we request approval to purge shallow wells utilizing a disposable polyethylene bailer instead of a 2-inch diameter submersible pump, as an option. 2. In order to save a substantial amount of money, we request approval to discharge purge water from the monitoring wells in the immediate vicinity of the wells. Results from previous groundwater sampling did not indicate significant contamination. This would negate the need for costly containment. If you have any questions, please feel free to contact me.

The purposef!this investigation was to obtain hydrogeologic and groundwater quality data to support expte n of the landfill into the northern borrow area and to delist the landfill from the New Yorks Registry of potential (Class 2A) hazardous waste sites. A Part 360/Phase II Investiaion Report was prepared in October 1991 and submitted to NYSDEC together with a Deing Petition. i i • The landfill was delisted by NYSDEC in October 1993. • Two subsequent sampling events were performed in July 1992 and January 1993 as p>ri't of the Landfill Operational Monitoring Program. Monitoring reports were preparid' in December 1992 and March 1993 and submitted to NYSDEC. I • The landfill was closed in September 1993. • The Town of Southold worked primarily with the Towns of Riverhead and East Hampt¢ ag well as Southampton and Shelter Island; and Twomey, Latham, Shea and Kelley; and F Isler, to develop the East End Towns' Regulatory Relief Initiative, which was prep in July 1994. The purpose of this Initiative was to seek relief from costly landfill closureder the NYSDEC Part 360 regulations. This document laid the foundation for the landfill cl 5 ire Varia►nee Requests submitted to NYSDEC in February 1995. • NYSDEC approved three of the Variance Requests (Gas Venting Layer [5 to 10% ifines passing a No. 200 slave]; Barrier Protection Layer [24" to 12" in thickness]; and Ti oil EquiWAttit) in August 1495. The Variance Request that was not approved (or conditi ly approved) was the reduction in monitoring. The Town will need to justify the reducti� in monitoring with additional sampling as specified in the Stipulation Agreement as nego f ted between the Town and NYSDEC. • The Stipulation Agreement to close the landfill and meet the NYSDEC closure require nts with agreeded upon Variance Requests was signed in October 1994. � • As part of the Agreement, the :iraft Closure Investigation Work Plan was prep" 6d submitted to NYSDEC in February 1994. Comments on the draft Work Plan were rec�i�l ed fiom NYSDEC in November 1995, and the revised/final Work Plan was subtnitt to NYSDEC in December 1995. The remaining stipulations in the Agreement regarding ctlure .; of the landfill are the following: i 1. Completion of the Closure Investigation and submittal of the draft Closure Investigation Report (CIR) within 150 days of NYSDEC Work Plan approval. Based on submit{ �q II � 4 1027\00103602(xol) i i BY:Xerox Telecopier 70% 4-96 ; 10:5MA 51F 60-4 7347978:# 3 the final Work Plan in December, the CIR is required to be subnutted to NYSDEC b It end of May 1996. This requires that the field program be initiated in February 1996. 2. Submit draft Closure Plan (construction drawings and specifications) to NYSDEC vJit'itin 180 days following DEC's approval of the CIR. II 3. Submit final Closure Plan incorporating NYSDEC's comments within 60 days of relc ipt of DLC comments. i 4.

DEC has not responded to date. • A Briefing Document requesting relief from costly Part 360 landfill closure was prepared and presented to the Governor's Office of Regulatory Relief and NYSDEC in June 1905) the Town's proposed closure plan was based on an "ecosystem" cover, rather than a syniih is cover. The Office of Regulatory Relief was receptive to the Town's proposed closure! lan and NYSDEC requested additional information/technical justification regarding use of Ithe USEPA's Hydrogeologic Evaluation of Landfill Performance(HELP)Model. • In order to use the HELP Model, as well as for developing a grading plan for closure 8f the landfill, tt topographic survey of the existing landfill is required. This survey and ma ,ng has beet► recent) completed December 1995) and the HELP Model is currently Wing y p ( prepared. • A test pit/limit of waste investigation was conducted in March 1995 and a report prepaied in April 1995. This investigation was conducted to determine the limits of waste dispose ,�for landfill closure and evaluate consolidation of the landfill to reduce closure costs, and to i0st in using the HELP Model for assessment of a less costly cover/cap for the landfill. � II • As a result of a water quality complaint filed by Donald Grim, who has property north hnd downgradient of the landfill,the Suffolk County Department of Health sampled his wells land other private water supply wells north of the landfill. As a result of this sampling, the �+viater quality from both of Donald Grim's wells was confirmed not to meet drinking Water standards. In addition, the water quality from the well located on the property of(owneld by) National Bank was also found to exceed drinking water standards. Based on the contami�n is detected, it is possible that the landfill is a source of the well contamination, however,l ere may also be other sources, such as pesticides and possible waste disposal on the propero. Alternatives to provide Mr. Grim with water that meets drinking water standards are to 1�611 a shallow water table well (about 60-70 feet) with a variance from SCDHS or install ai deep well beneath the clay layer underlying the area(about 200 feet). i ♦1027k30103602(RUI) t 1 { SgfV C BY:Xerox Te l ecopier 7020 ;11-24-95 ; 2:34PM 515 364 9045-+ 516 765 1823# 1 Dvirka V and 0 Bardlucc!

PATAKI GOVERNOR November 10, 1995 Dear Mr. Wickham: Thank you for your letter and resolution regarding landfill closure regulations . As you know, I have created the Office of Regulatory Reform to review all regulatory requirements which include potential reforms regarding Landfill Closure Regulations found in 6 NYCRR part 360 . Part of the reform process involves weighing the environmental benefits of existing or proposed legislation against its cost . This can be a difficult process, especially with landfill closures since the allowable limits for residual contaminants are subject to change. That change could result in a huge cost that could have been avoided if the landfill had been closed earlier under less stringent requirements . I am forwarding your letter to the Office of Regulatory Reform to assist them in their review and I have asked the office to keep you informed on all developments .

Zagata Commissioner November 3, 1995 Supervisor Thomas Wickham Town of Southold Town Hall, Main Road Southold, NY 11971 Dear Supervisor Wickham: The Division of Solid Waste has reviewed the Landfill Closure Investigation Work Plan for the Southold (Cutchogue) Landfill prepared by Dvirka and Bartilucci Consulting Engineers and dated March 1995. Based on our review, the Department has the following comments: 1. Groundwater Sampling and Analysis A. Complete groundwater elevations must be taken during the sampling program and must be reported. A current groundwater flow map (for both deep and shallow wells) must be included with the Closure Investigation Report (CIR). B. This round of baseline sampling as described in the CIR can be considered the first of the three conditions outlined in the Town of Southold's Stipulation of Settlement" whereby the Town is requesting a reduction in the post-closure groundwater monitoring frequency. Completing the three conditions outlined in the settlement enables the Town to apply for the variance request reducing the monitoring requirements at the site. 2. Explosive Gas Investigation A. The workplan details an explosive gas investigation using a combination of permanent explosive gas monitoring points and temporary explosive gas • Supervisor Thomas Wiain 2 monitoring points. In most cases, the number of proposed monitoring points is adequate. However, the number of proposed monitoring points along the southwest properly line (between permanent monitoring points 1-8) is inadequate (see attached map). Temporary monitoring points (using the same spacing as proposed along the north, east, and southeast sides of the landfill) should be continued along the entire southern and southwest sides of the landfill. These points will be useful because they will provide a different level of gas monitoring, two to three feet deep for the temporary probes and about 25 feet deep for the permanent gas probes. These points are necessary because at the -southwest boundary of the landfill site are a number of inhabited dwellings and the permanent gas monitoring points are too widely spaced to provide adequate monitoring. B. The explosive gas investigation must require a radial or lateral step out whenever gas is detected at a monitoring point. The investigator must move 25 or 30 feet away from the landfill and retest every time gas is identified at a monitoring point. This stepout will help to identify any potential migration path and possible limit of gas migration. 3. Surface Leachate Survey A. Groundwater is 12 to 50 feet below ground surface at this site and any leachate generated would be expected to percolate vertically into the ground. Therefore, any identified leachate seep or stain must'include an explanation as to why the leachate seep occurs where it does. 4. Other Comments A. The CIR should include a limits of waste map. This map should include the proposed capping area. Any areas not included under the cap must be identified and an explanation of why they will not be capped, must be provided. B. The report must also address the issue of how landfill under the proposed compost facility will be capped and monitored with special reference to gas venting. C. Water Well Survey - There are a number of water supply wells close to the landfill. The Scope of Work does not include any discussion about the groundwater quality or.the possible contamination of the nearby private wells. The workplan contains no provisions for the testing of private water wells. A number of these wells should be sampled for groundwater quality and possible contamination.

Wickham, Supervisor Town of Southold ( `Z Town Hall 53095 Main Road P.O. Box 1179 Southold,NY 11971 I/ Re: Town of Southold Landfill D&B No. 1314 Dear Supervisor Wickham: As requested, provided below is an outline for a scope of work and budget estimate to prepare a report which provides justification for "simple" closure of the Southold Landfill, as well as to develop costs for water supply alternatives for residences downgradient of the landfill. With regard to closure justification, the report will focus on the results of the groundwater sampling program conducted in 1991, 1992 and 1993, which showed little impact on groundwater quality caused by the landfill, and little or no impact on private wells located downgradient of the landfill. Based on this assessment, recommendations will be provided for closure of the landfill; these being the following: 1. In the area of the mounded eastern portion of the landfill, the area will be graded to promote runoff to minimize infiltration of precipitation through the landfill. Two feet of soil cover will be placed over the graded area and vegetation will be established to promote evapotranspiration, again to minimize infiltration of precipitation. 2. In the area of the flat western portion of the landfill, the area will be capped with asphalt which will support the planned yard waste composting facility and mitigate infiltration of precipitation through that portion of the landfill. 3. A monitoring program will be implemented to assess the impacts of the landfill and closure on groundwater and water supply quality. This program will initially be in accordance with the Part 360 regulations, but variances to the monitoring program, (at a minimum as provided in the Stipulation Agreement)will be developed after the first year(or two) of sampling. OVIRKA AND BARTILUOCI Thomas H. Wickham, Supervisor Page Two Town of Southold May 17, 1995 4. As part of the Closure Plan, a contingency plan will be developed to protect human health and the environment should the monitoring program show significant adverse impacts on groundwater or water supply quality caused by the landfill. Development of the contingency plan will consider the following alternatives: A. Groundwater extraction and treatment. B. Provision of treatment systems for private wells. C. Construction of deep private wells. D. Development of a community water supply system. E. Connection to the Suffolk County Water Authority public water supply system. F. Acquisition of properties/houses. Costs, together with a discussion of the "pros and cons," will be developed for each of these alternatives so that the Town can select the contingency plan it feels is the most appropriate for inclusion into the Closure Plan. The estimated budget for the preparation of this document, including the evaluation of groundwater and water supply alternatives, is $12,000. If savings can be accrued in the course of data gathering, in particular, to develop costs of the alternatives, we will make every attempt to reduce the cost of the report.

Wickham, Supervisor Town of Southold Town Hall �- 53095 Maui Road PO Box 1179 Southold,NY 11971 Re: Southol dfill T t and Waste Delineation Program &B No. 1314 Dear Supervisor Wickham: Please find enclosed a draft report which describes the activities performed and results of the recently completed test pit program conducted at the Southold Landfill. The purpose of this test pit program was to define the characteristics and limits of waste disposed at the landfill for purposes of development of a closure plan, including waste consolidation to reduce closure costs, and a land use plan for the site, including construction of a yard waste composting facility. This program was performed with the support of Mr. James Bunchuck and other Town staff who assisted greatly in the field work. The results of the test pit program, which comprised the construction of 60 test pits and trenches around the perimeter of the landfill, and in a grid in the flat area of the western portion of the landfill,are the following: 1. Except for the southeast quadrant of the landfill,buried waste comprises a combination of municipal solid waste (MSW) and construction and demolition debris (C&D). The southeast quadrant comprises essentially all MSW. 2. The area of buried waste comprises approximately 30 acres. 3. Based upon a 5-foot depth of waste being a break point for cost-effective waste consolidation, there is little opportunity for consolidation of waste at the landfill. Minor opportunity for consolidation, perhaps a few acres,exists along the western and southern boundaries of the landfill. 4. In a few areas along the northern, eastern and western landfill boundaries, waste extends essentially to the property line, which does not meet the requirements of the Part 360 regulations for closure. (The regulations require a minimum of 50 feet between the property he and the limits of waste.) As part of closure,removal of waste within 50 feet of the property boundary may be required unless a variance can be obtained. gVIRKA AND BARTILUCCI Thomas H. Wickham, Supervisor Page Two Town of Southold April 26, 1995 Based on the above results,the following is recommended as a Closure Plan for the landfill: 1. In the area of the mounded eastern portion of the landfill, the area should be graded to promote runoff to minimize infiltration of precipitation through the landfill. Two feet of soil cover should be placed over the graded area and vegetation established to promote evapotranspiration, also to minimize infiltration of precipitation. 2. In the area of the flat western portion of the landfill, the area should be capped with asphalt which will support the planned yard waste composting facility and mitigate infiltration of precipitation through that portion of the landfill. 3. A program should be developed to monitor the impacts of the landfill and implementation of the Closure Plan on groundwater and water supply quality. This program would initially be conducted in accordance with the Part 360 regulations,but variances to the monitoring program,(at a minimum as provided in the Stipulation Agreement)will be developed after the first year of sampling. 4. As part of the Closure Plan, a contingency plan should be developed to protect human health and the environment should the monitoring program show significant.adverse impacts on groundwater or water supply quality caused by the landfill. The cost to undertake the test pit program, which included provision of a geologist to supervise and record the results of the test pit excavation for a period of eight days and preparation of the enclosed report was $5,600. This effort is part of preparation of the required Closure Plan and will be invoiced as a new task If you have any questions or comments with regard to the report, or require additional information, or would like a presentation to be made to the Town Board regarding the work conducted and results of the test pit program,please call me.

Cowan: Kindly consider this letter the Town of Southold ' s revised, updated reclamation plan and variance request for the ± 5 acre mined area to the north of the cutchogue landfill . This letter is filed pursuant to Section TIG of the Stipulation of Settlement, dated October 5 , 1994 and is intended to supplement the mining and reclamation plan dated June 1986 , previously filed with the Department . The 1986 plan should be revised to add the northeasterly corner of the sand r,it as part of the designated area that has been mined. That area is shown by crass-hatching on the attached site plan. The slopes in that area will be restored to a 2 : 1 grade by scaling back the top of the slope to the east . A visual inspection of the remainder of the pit area reveals that the slopes have, for the most part, stabilized over that past several years, and indeed, sustained plant growth exists throughout . Slope stabilization and grading will be implemented in those isolated areas of the pit where erosion appears to be occurring. The 1986 reclamation plan is revised to delete possible use of the pit area for landfilling of municipal solid waste. The area will be used as a stormwater recharge basin. At some future date, the Town may choose to utilize the area for yard waste composting. That alternative, should it be pursued, would be coordinated with the Department . A variance from the 25 foot setback is requested as contemplated in the October 5 , 1994 Stipulation of settlement .

Residents drive into the collection building and deposit their bags of refuse in the trough that runs the length of the building, Carters drive their vehicles directly Into the lower portion of the building and dump their load directly in the trough. The waste is loaded from the trough into the trucks that transport the waste out of town. Once this portion of the collection building ceases to be used as a temporary transfer station, the trough and related areas will be cleaned so as to be free of waste and debris. It is anticipated that all structures will remain in place. How this area of the collection building will be used thereafter will be dependent on the long-range disposal plan adopted by the town. In addition to being used as a transfer facility, the collection building is used as part of the collection of recyclables and household hazardous wastes. Indeed, the town has recently received a new, three year permit for the STOP facility. The building also houses a shop and had been used in the past for storage of landfill equipment. One option will be to incorporate that portion of the collection building into a permanent transfer station. Alternatively, this area of the building could be converted and adapted to become part of the Town's recycling facility. In any event, upon cessation of its use as a temporary transfer station, that portion of the building that had been used as the temporary transfer station will be broom clean.

The funds available from the EFC are available in two programs: (1) a long-term SRF loan program which provides low-interest loans to municipalities to finance water treatment projects and (2) a short-term finance program to provide interest-free loans to municipalities to complement the long- term loan program. Short-Term Finance Program ("STFP"): The STFP will make interest-free loans to municipalities for eligible projects in an amount not to exceed $4,000,000 for a loan term of up to two (2) years. The loans can be used to pay for planning, design and construction costs that accrue regarding municipal solid waste projects before the long-term financing is needed. Application for SRF money involves the following: 1. Letter from municipality requesting the project be listed. 2. Description of the project and the problems that it will correct. October 14, 1994 Page 2 3. Documentation of the impact of the existing condition and the proposed project (landfill closure in this case). 4. Copy of an enforceable order or permit requiring the project to be built or action to be undertaken (Consent Order and/or variances). 5. List of target dates for completion of the closure investigation report, closure plan, construction start and construction completion and a preliminary estimate of the project costs. We have been advised by the EFC that application for funding should be filed by letter at the earliest possible date to reserve priority on the funding list. Long-Term Funding: The EFC also provides 30-year low-interest loans to municipalities for landfill closure projects. These loans are available at a rate that currently represents a 1/3 subsidy of the existing AA rated bond rate. That is, the loan rate should yield a savings of approximately 1/3 of what the interest rate would be for the town should it issue its own bonds for this project. The application for long-term funding can be made upon completion of the technical design of the project. To obtain further information about both of these loans the EFC contact persons are Robert Davis or Kumar Nepal at 1-800-882-9721 or (518) 457-4100. For you convenience, I have prepared a draft letter that may be utilized to make the initial application by the town to reserve a listing for project eligibility on the SRF. PER:JML -46 , • • October 14, 1994 Terry Agriss, President New York State Environmental Facilities Corporation 50 Wolf Road Albany, New York 12205-2603 Dear Ms. Agriss: This is to request that the landfill owned by the Town of Southold be included as a project on the State Revolving Fund for Water Pollution Control Project priority list. Briefly this project will entail landfill closure of the Town's only landfill pursuant to 6 N.Y.C.R.R. Part 360 regulations and the Consent Order entered into between the New York State Department of Environmental Conservation and the Town of Southold and subsequent amendments thereto. As agreed in the Consent Order, the Town of Southold will [You must set forth some technical work that will be done at the landfill to protect groundwater. For example, "augment its existing groundwater monitoring networks at the landfill", or "perform periodic sampling of existing wells", or "cap the landfill to prevent leaching of contaminants into the groundwater".] The purpose of the project is to comply with New York State law requiring that all landfills on Long Island be either capped or reclaimed so that precipitation does not infiltrate through the waste mass down to the water table and potentially impact the quality of groundwater beneath the landfill. The Town has chosen to cap the landfill so that precipitation will no longer infiltrate the waste mass. The present water quality data are presented in the enclosed [whatever water quality data has been compiled should be included.] . .-s Terry Agriss, President October 14, 1994 Page 2 We have enclosed for your reference and review the Consent Orders and amendments thereto entered into between the New York State Department of Environmental Conservation and the Town of Southold on requiring the projects to be completed as described above. The Town has estimated the project cost for capping the landfill to be approximately $ . Groundwater monitoring costs over the 30-year required period are estimated to be approximately $ The Town of Southold expects to complete its Closure Investigation Report for the landfill within the next — months. Upon completion of the CIR, the Town would ask that its eligibility for short-term financing from the State Revolving Fund be considered complete. It can be seen from the enclosed Consent Order that before the Town can proceed to long-term implementation or closure planning, design and construction initiation will require additional funding. The Town of Southold fully expects to make application for long-term financing upon completion of its Closure Plan. If your office requires additional information, please contact me directly. Thank you for your assistance in this matter.

The c nceptual closure glan, which is included as Section 3 of the Closure Investigation Report, does not meet the minimum requirements of 6NYCRR Part 360 Subdivision 360-2.15. The department may approve the use of alternative closure concepts at landfills which are not negatively impacting the environment. Due to documented groundwater impacts from this landfill, a more conservative conceptual closure plan will be required to remedy the groundwater impacts from the landfill. However, the Departm has in the past entertained the concept n asphalt capping system over the R/westem area of the landfill which would serve as a base to facilitate a yard waste composting site over the ylandfill cap. The Department will require a detailed engineering report about the-feasibility of an asphalt cap for the western area of the landfill in order to evaluate the viability of this alternate capping method. In reference to the plans for the complete and partial reclamation in the eastern area of the landfill site, the applicant has missed the deadline for submission of a feasibility study report for such a proposal as t outlined in the compliance Schedule and will require a modification.of the Stipulation-of-Settlement. To , Vt''V evaluate the merits of a second alternate capping plan with va otrans iration capping system, he �. Department will require that a detailed project report be submitted which could a permitted un er the provisions of 6NYCRR Part 360 Subdivision 360-1.13. However the fact that residential wells are being impacted by the landfill is a strong reason to avoid a long term project such as reclamation.

PATAKI GOVERNOR November 10, 1995 Dear Mr. Wickham: Thank you for your letter and resolution regarding landfill closure regulations . As you know, I have created the Office of Regulatory Reform to review all regulatory requirements which include potential reforms regarding Landfill Closure Regulations found in 6 NYCRR part 360 . Part of the reform process involves weighing the environmental benefits of existing or proposed legislation against its cost . This can be a difficult process, especially with landfill closures since the allowable limits for residual contaminants are subject to change . That change could result in a huge cost that could have been avoided if the landfill had been closed earlier under less stringent requirements . I am forwarding your letter to the Office of Regulatory Reform to assist them in their review and I have asked the office to keep you informed on all developments . Very truly yours, Honorable Thomas Wickham Supervisor Town of Southold P.O.

Based on our review, the Department has the following comments: 1. Groundwater Sampling and Analysis A. Complete groundwater elevations must be taken during the sampling program and must be reported. A current groundwater flow map (for both deep and shallow wells) must be included with the Closure Investigation Report (CIR). B. This round of baseline sampling as described in the CIR can be considered the first of the three conditions outlined in the Town of Southold's Stipulation of Settlement" whereby the Town is requesting a reduction in the post-closure groundwater monitoring frequency. Completing the three conditions outlined in the settlement enables the Town to apply for the variance request reducing the monitoring requirements at the site. 2. Explosive Gas Investigation A. The workplan details an explosive gas investigation using a combination of permanent explosive gas monitoring points and temporary explosive gas Supervisor Thomas W*am • 2 monitoring points. In most cases, the number of proposed monitoring points is adequate. However, the number of proposed monitoring points along the southwest properly line (between permanent monitoring points 1-8) is inadequate (see attached map). Temporary monitoring points (using the same spacing as proposed along the north, east, and southeast sides of the landfill) should be continued along the entire southern and southwest sides of the landfill. These points will be useful because they will provide a different level of gas monitoring, two to three feet deep for the temporary probes and about 25 feet deep for the permanent gas probes. These points are necessary because at the .southwest boundary of the landfill site are a number of inhabited dwellings and the permanent gas monitoring points are too widely spaced to provide adequate monitoring. B. The explosive gas investigation must require a radial or lateral step out whenever gas is detected at a monitoring point. The investigator must move 25 or 30 feet away from the landfill and retest every time gas is identified at a monitoring point. This stepout will help to identify any potential migration path and possible limit of gas migration. 3. Surface Leachate Survey A. Groundwater is 12 to 50 feet below ground surface at this site and any leachate generated would be expected to percolate vertically into the ground. Therefore, any identified leachate seep or stain must include an explanation as to why the leachate seep occurs where it does. 4. Other Comments A. The CIR should include a limits of waste map. This map should include the proposed capping area. Any areas not included under the cap must be identified and an explanation of why they will not be capped, must be provided. B. The report must also address the issue of how landfill under the proposed compost facility will be capped and monitored with special reference to gas venting. C. Water Well Survey - There are a number of water supply wells close to the landfill. The Scope of Work does not include any discussion about the groundwater quality or the possible contamination of the nearby private wells. The workplan contains no provisions for the testing of private water wells. A number of these wells should be sampled for groundwater quality and possible contamination.

As you are aware, the closure construction plans and specifications were approved by the Department in a letter dated December 23, 1999, and it was the Town of Southold's intent to bid the project in late January. However, two situations have developed which have precluded the Town from bidding the project, these being the need to resolve the replacement of the transmission towers on the landfill with LIPA and securing of construction easements on properties adjacent to the landfill from reluctant property owners. The Town has been attempting to resolve these matters over the past few months and is continuing to resolve them. Until these matters are resolved, however, the Town feels it is prudent not to bid the project and, as a result, the schedule for closure construction has been delayed. Based on best available information and the hope that the above matters can be resolved in the near future, the Town is hoping to bid the project in late March. Your understanding of this situation is greatly appreciated. If you have any questions or require additional information, please do not hesitate to call me. Very truly yours, Thomas F. Maher, P.E.

As a result of discussions with Mr. Ernie Lampro of your office, a copy of the Closure Plan also is being directly transmitted to Ms. Melissa Treers of the Albany office. During the site visit with Ms. Treers, Mr. John Vana and Mr. Lampro on June 23, 1998, because of the substantial amount of off-site fill material required to attain a 4% slope on the western portion of the landfill (approximately 46,000 cy), we discussed the concept of submitting both a 2% and 4% grading plan for the western portion of the landfill. (The eastern portion of the landfill will be only at 4% slope.) The Department was agreeable to this concept which would require provision of technical justification in the Closure Plan regarding a possible variance to allow for a 2% slope.- This draft Final Closure Plan contains Subgrade Grading Plans for both 2% and 4% slopes in the western portion of the landfill, and an evaluation of cap hydraulic efficiency, settlement and drainage pertaining to the 2% slope concept. Although the 2% slope does not appear viable based upon evaluation of settlement and drainage, since approval of the grading plan is contingent upon review of this draft plan, we have not prepared Final Grading Plans for closure at this time. After selection/approval of either a 2% or 4% slope for the western area by NYSDEC, a Final Grading Plan will be prepared and submitted to your office. Submittal of only the Subgrade Plans in the enclosure was discussed with and approved by Ms. Treers. A DIVISION OF WILLIAM F.COSULICH ASSOCIATES,P.C. I OVIRKA AND BARTILUCCI Anthony J. Cava, P.E.

As you also are aware. initially the 'Town of Southold planned to utilize the western portion of the landfill for its yard waste composting program, and a preliminary contour grading and drainage plan was developed to reflect this intended use. The initial plan was discussed with your staff in March to receive preliminary comments. Based on these comments, which primarily involved concerns regarding provision of adequate drainage due to the shallow slopes proposed for the composting pad, as well as comments on the Conceptual Closure Plan, which primarily involved concern regarding potential damage to the cap as a result of composting activities, the Town has decided to relocate the composting facility to the borrow area in the northeast corner of the landfill property. Not only will this change alleviate your Department's concerns, but also will reduce the amount of contour grading material needed to develop the area for tine initially planned compost area, and allow more drainage to the southwest corner of the landfill property, thereby negating the need to construct a subsurface piping system to convey ntnoff to the northeast portion of the landfill.

Blackman Environmental Engineer IV Division of Solid Waste NYS Department of Environmental Conservation 50 Wolf Road, RM 202 Albany, NY 12233 Re: Southold Landfill Dear Mr. Blackman: This is to provide you with a progress report concerning development of a closure plan for the Southold Landfill, following our meeting at the Association of Towns' Office with you and other NYSDEC staff and representatives of the Governor's Office on Regulatory Reform on June 22, 1995. As you are aware, the Town of Southold is extremely concerned about the substantial cost of the typically required Part 360 landfill closure involving construction of a geomembrane or clay soil cap, which is currently being required for closure of the Southold Landfill. As explained during our meeting, based on environmental data, it does not appear that this landfill poses a significant threat to human health or the environment, and can be closed in a more cost-effective manner, including construction of the "ecosystem" cover which we presented in a briefing document presented at the June 22nd meeting to mitigate leachate generation. Following the meeting, you had suggested that we utilize the USEPA Hydrologic Evaluation of Landfill Performance (HELP) Model to demonstrate the effectiveness of our proposal for landfill closure. As a result of your suggestion, we have directed our engineering consultant, Dvirka and Bartilucci Consulting Engineers (D&B) , to undertake this modeling. At this date, D&B has set up the model and performed a preliminary evaluation. In order to address the Southold Landfill on a site-specific basis, we are in the process of preparing a topographic map of the landfill and should have the map completed in about 30 days, after which D&B will prepare a rough closure grading plan. Following preparation of the grading plan, D&B will run the model for a geomembrane and/or 10(-5) cm/sec soil cap, and the "ecosystem" cover, to determine the effectiveness of these caps/covers. David E. Blackman Environmental Engineer IV Page Twp September 15, 1995 We hope to have a report on the modeling results prepared by he end of October, after which we will forward a copy to you for review.

Cowan, P.E. Regional Director NYSDEC Building 40 SUNY Stony Brook, N.Y. 11790-2356 re: Revision to Mining Reclamation Plan and Variance Dear Mr. Cowan: Kindly consider this letter the Town of Southold' s revised, updated reclamation plan and variance request for the t 5 acre mined area to the north of the Cutchogue Landfill. This letter is filed pursuant to Section IIG of the Stipulation of Settlement, dated October 5, 1994 and is intended to supplement the mining and reclamation plan dated June 1986, previously filed with the Department. The 1986 plan should be revised to add the northeasterly corner of the sand pit as part of the designated area that has been mined. That area is shown by cross-hatching on the attached site plan. The slopes in that area will be restored to a 2 : 1 grade by scaling back the top of the slope to the east. A visual inspection of the remainder of the pit area reveals that the slopes have, for the most part, stabilized over the past several years, and indeed, sustained plant growth exists throughout. Slope stabilization and grading will be implemented in those isolated areas of the pit where erosion appears to be occurring. The 1986 reclamation plan is revised to delete possible use of the pit area for landfilling of municipal solid waste. The area will be used as a stormwater recharge basin. At some future date, the Town may choose to utilize the area for yard waste composting. That alternative, should it be pursued, would be coordinated with the Department. A variance from the 25 foot setback is requested as contemplated in the October 5, 1994 Stipulation of Settlement. Thank you once again for your coope t on and assistance. If you have any questions or need any ad i ional information, please do not hesitate to contact me. Sincer y, aG Thomas Wickham Supervisor Enclosure cc: F. Isler M.

Cowan, P.E. Regional Director NYS Department of Environmental Conservation Building 40 SUNY Stony Brook Stony Brook, N.Y. 11790-2356 Re: Clean-Up Plan for Temporary Transfer Station Dear Mr. Cowan: Enclosed please find the Town's "clean-up plan" for the temporary transfer station. This plan is submitted in compliance with paragraph 6 of your letter of authorization of September 29, 1994 . Thank you once again for your cooperation an ssistance. Very trul yours, Thomas H. Wickham Supervisor Enclosure CLEAN-UP PLAN FOR TEMPORARY TRANSFER STATION (Facility Identification No. 52 T 92) STATEMENT This statement is being submitted in compliance with paragraph 6 of the letter of Ray E. Cowan, P.E. , dated September 29, 1994 to Supervisor Wickham, and is intended to supplement section 5. 11 [Closure of the Temporary Transfer Operations] of the Engineering Report of Dvirka and Bartilucci , dated September 1993. CLEAN-UP PLAN Upon cessation of the temporary transfer station operation, the site will be policed to be free of waste and debris. Presently, the transfer station operates as described in the Engineering Report of September 1993. Residents drive into the collection building and deposit their bags of refuse in the trough that runs the length of the building. Carters drive their vehicles directly in the trough. The waste is loaded from the trough into the trucks that transport the waste out of town. Once this portion of the collection building ceases to be used as a temporary transfer station, the trough and related areas will be cleaned so as to be free of waste and debris. It is anticipated that all structures will remain in place. How this area of the collection building will be used thereafter will be dependent on the long-range disposal plan adopted by the town. In addition to being used as a transfer facility, the collection building is used as part of the collection of recyclables and household hazardous wastes. Indeed, the town has recently received a new, three year permit for the S.T.O.P. facility. The building also houses a mechanic's shop and had been used in the past for storage of landfill equipment. One option will be to incorporate that portion of the collection building into a permanent transfer station. Alternatively, this area of the building could be converted and adapted to become part of the Town's recycling facility. In any event, upon cessation of its use as a temporary transfer station, that portion of the building that had been used as the temporary transfer station will be broom clean. {V c�� � `7 .•s JAMES BUNCHUCK c y< P.O.

Some of the work has occurred already, some has yet to be done. The addendum would increase the budget for Task#2 of the contract(i.e., "Preparation of Closure Plans and Specifications")by a total of$98,900. The work authorized by this increase has already resulted in about $150,000 in savings in cap construction costs, and could ultimately save as much as$456,000. The attached letter of November 18 from Tom Maher to Mary Wilson outlines the expected savings. Please contact me if you have any questions regarding this proposed addendum.
