This engineering report and accompanying plans will demonstrate that, if granted the permit, the facility will continue to not pose a nuisance to its neighbors. In addition, it will continue to operate in compliance with NYSDEC Solid Waste Management Policy identified in section 27-0106 under the ECL and NYCRR Part 360 1.14. This document supplements two earlier engineering reports listed immediately below for the Compost and Landfill facilities. These reports are attached as Appendix's A and B respectively: • Engineering Report dated November 2001 — Yard Waste Compost Facility, prepared by 1-12M Group • Post -Closure Monitoring and Maintenance Manual for Southold Landfill, dated August 2003, prepared by Dvirka and Bartilluci • The MSW transfer station and the C&D transfer station currently have individual NYDEC Registrations, while the compost facility has a NYSDEC permit. The purpose of this permit application is to unify the NYSDEC authorizations to operate under a single unified permit rather than 2 separate registrations and permit. • I• TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT 1.2 Site Description The Southold Solid Waste Management Facility is located between Oregon Road and • North County Road 48 to the north and south, respectively, and Cox Lane and Depot Lane to the east and west respectively, Suffolk County, New York. The site is in a rural, agricultural area of Cutchogue, approximately 2.5 miles east of Mattituck and 8 miles west of the incorporated Village of Greenport. • The property is shown on the Suffolk County Tax Map as the following parcels; District 1000, Section 96, Block 01, Lot 17.5 and District 1000, Section 96, Block 01, Lot 02 • The current land owner is the Township of Southold who is also the applicant for the NYSDEC Part 360 Permit to Operate. A Regional Settings Map is included in the Appendices as Appendix C. Additionally, an overall site plan is included as Appendix D. 1.3 Types of Waste to be Accepted and Quantities Residential and Commercial Waste including recyclables, unprocessed Construction and Demolition (C&D) Waste and Yard Waste will be accepted at this facility. Approval is requested to accept up to: • 5,000 tons per year of C&D waste. • • 25,000 tons per year of MSW waste • 4,000 tons per year of recyclables (Comingled and ONPICC) • 42,000 yards per year of Yard Waste n u 1.4 Prohibited Siting The site is not located within Critical Environmental Area designated pursuant to Article 8 of the ECL. The land is not within an agricultural district, and there are no floodplains, endangered species or wetlands on the site. There are no reservoirs, reservoir stems, • TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT controlled lakes, or watersheds managed pursuant to a filtration avoidance determination in the vicinity of the site. 1.5 Service Area The service area for the Town of Southold Solid Waste Management Facility is the Towns of Southold, Riverhead and Shelter Island. i 1.6 Site History The closed landfill property is approximately 34 acres, the MSW transfer station facility is approximately 11 acres, the compost facility is 17.2 acres and the C&D r transfer area is approximately 2.5 acres. The entire parcel is zoned for light industry use. The Town of Southold initiated operations in the landfill site in 1920 for the disposal of solid waste, refuse debris and scavenger (system) waste and operated the landfill continuously until 1993 when it was closed. At that time, an outdoors transfer station was set up which was subsequently demolished and a new state of the art transfer station building was constructed in 2006 and opened for business in 2007. 7 Ll r, TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT • 2.0 Operational Plans • 2.1 Transfer Station Description of Operations A new transfer station Facility was constructed in 2006 and opened for business in 2007. The estimated service life for the transfer station building, scale house and scales is twenty five years. The building is sized to have a capacity to hold approximately 350 tons of MSW. Please see Appendix E for site plan for the MSW Transfer Station. The facility is situated on approximately 11 acres of land and consists of the following structures and elements: • The main transfer station building is a 21,195 square foot steel building. The building includes a tipping floor, a truck load out tunnel, a mechanic's shop and various waste storage bunkers. The tipping floor has been armor coated to protect the floor surface and all interior building steel has been epoxied coated to protect against metal corrosion due to the high moisture environment in the building. • • New inbound and outbound weigh scales and scale house. • Long ( approx. 1,000 feet) entry/service road to scales for vehicle queuing 0 • Administration Offices • Residents recyclables and waste drop-off area • • Residents Home Exchange • Storage Bins for battery disposal, clothing and other material OR • Storage bunkers for white goods, bulk items and C&D • Waste oil storage Tank The facility will accept only residential and commercial MSW; no other types of solid waste will be accepted. The applicant is seeking an approved design capacity of 25,000 tons per year of 4 TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT waste at this facility. Vehicles will enter the site from the main entrance on Cox Lane after passing through the entrance gate, and proceed to the scale house for weight in. Here vehicle identification is made along with a description of the vehicle contents. All waste generators are required to identify the source(s) of the waste. All hauling vehicles are entered into a computerized system identifying company name, company owner, type and size of vehicle, and unloaded weight of vehicle. The computer system is used to determine daily waste input to the facility. Once vehicles are weighed, they are directed to the tipping floor. Trucks back into the tipping area and discharge their contents inside the building. Vehicles without tare weights exit the tipping area and need to stop at the scale house to be re -weighed and to sign a receipt. Vehicles with tare weights can immediately leave the site after dumping on the tipping floor. Waste and recyclables are dumped onto the tipping floor is then reloaded by payloader into 100 cubic yard walking floor trailers for transport to out of town disposal facilities. Solid waste handling shall be confined to the smallest practical area. Handling of all materials will be supervised by trained competent personnel at all times. All employees will be trained and familiar with proper operational procedures. The trailers are staged in the facilities "load -out' tunnel on the north side of the building. Residents also can dispose of their household waste on the east side of this facility at the Residents Recyclables and Waste Drop off Area. Dumping areas for residents will be clearly marked and separated from large commercial vehicles coming into the transfer station tipping floor. Residents may throw household waste and recyclables over a low parapet wall in to one of five storage bunkers and/or one of two self -dumping hoppers. The five storage bunkers and two hoppers (please see Appendix E) are dedicated to the following waste types: 1. Residential waste : 1 bunker, sized at 30 ft.x18 ft. 2. Residential glass, plastic and cans: 2 bunkers, each sized at 30 ft.x18 ft. 3. Residential cardboard: 2 bunkers each sized at 20 ft.x18 ft. 4. Residential paper: 2 self -dumping hoppers with a capacity of 1.5 cy each. In order to comply with this regulation, all MSW delivered to the site will be indoors inside the transfer building. Waste streams are kept separate at all times in accordance with NYCRR Part 360-16.4 (f)(3). The building is sufficiently large to handle the Towns waste stream including seasonal and peak periods. Since the transfer station facility opened in 2007, waste has never been unloaded outside the building. TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT ` NYSDEC regulations also require the installation of a scale system to weigh and record waste quantities received at this facility. Accordingly, shown on the site plan is an inbound and outbound scale, together with a small scale house in compliance with NYSDEC regulations. 2.1.1 Schedule of Operation Transfer station operations are conducted on all seven (7) days in the week. The hours of operation for this facility are from 7:00 AM to 5:00 PM. Waste deliveries to the • facility are predominantly in the morning hours with most deliveries received by 2 PM. This allows for the tipping area to be cleared and the solid waste transferred out by the end of the each working day. Every effort is made to keep the tipping area cleared and housekeeping activities completed at the end of each working day. This reduces the potential of adverse conditions developing in the waste receiving area • Prior to opening each day of operation, the Facility Operator shall examine the adjacent properties and main entrance roadway for any waste illegally dumped during "off' hours. Once a perimeter inspection has been performed, the Facility Operator shall open the gate to the facility, the Facility Operator shall perform a "Start -Up" inspection on a daily basis examining the following items: • Make sure all regulatory signs are visible. • • Inspect first aid kit, personal protective equipment and fire extinguishers for proper use. • Examine all equipment to be used in Transfer Station Operations. • Inspect tipping floor, loading ramps, overhead doors and building for damage or vandalism. • Make sure all water hoses work properly. • Monitor area surrounding Transfer Station Building for fugitive litter. • Examine sanitary facilities for adequate function. • Inspect all stairways, fixed ladders, doorways for emergency access. • Examine walking/working surfaces for safe working conditions • Acknowledge electric power to Facility. • Maintain positive "lock -out" procedures where applicable • Examine all maintenance equipment • • Inspect Facility's Stormwater/Drainage Systems and Erosion Control • Perform "self -test" of scale for accuracy and proper measurement of weight. 6 0 TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT After completion of the perimeter and start-up inspections, the facility operator will open up the gates of the facility. Upon closing down each day, the Facility Operator shall perform a "Shut -Down" • inspection consisting of the following items: • • Examine tipping floor areas for proper placement and separation of recyclables, unauthorized waste, and MSW waste. • In the event that waste remains on the tipping floor at the end of the day, account for all residual/commercial MSW in the facility (approximate volume). • Inspect Perimeter for Litter and other Vectors. • Check to see if facility gates are locked. The above referenced "Start -Up" and "Shut -Down" procedures shall be executed on a daily operating basis as per Part 360-16.3 (d) (4). 2.1.2 Site and Building Design/Size The facility is fenced to limit access and the grounds are landscaped appropriately to provide aesthetic screening. The facility is well lighted and appropriate signage is present to alert the • public that only authorized personnel are allowed on the site. The Transfer Facility has been developed with all activities being conducted under cover. The building is sized to have a capacity to hold approximately 350 tons of MSW. With a permit limit of 25,000 tons per year of MSW waste requested and an annual operating period of 351 days, the average daily capacity at this facility is calculated to be 71 tons per day. This translates into a storage capacity for MSW of 5 days if necessary during normal non -peak periods. • 2.1.3. On -Site Roads Bituminous pavement has been installed on all access roads and general outside paving for queuing areas and vehicle parking. • 9 u TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT 2.1.4. Drainage The site design includes adequate drainage facilities to retain any storm water on-site. All run- off from paved areas is directed to on-site leaching pools. 2.1.5 Water Supply & Sewage Disposal System The site is serviced with public water from a SCWA water main on Middle Country Road. There is an on-site sewage disposal system (septic tank and leach fields) located on the west of the main transfer station building. 2.1.6 Security The entire property is secured with 6' high chain link fencing. The entrance gates on Cox Lane are locked at the end of work each day. There are no personnel on the premises during the evening hours. The facility is well lighted and appropriate signage is present to alert the public that only authorized personnel are allowed on the site. No drop-off or salvaging by the public is allowed. Authorized visitors are escorted by facility personnel at all times. 2.1.7 Fire Protection In the case of the main MSW transfer station building, fire extinguishers will be strategically located throughout the tipping floor area. All fire extinguishers are capable of fighting class A, B and C fires as defined b Underwriters Laboratories. Fire detections stems are in accordance Y Y with 29 CFR 1910.164 and applicable local rules and regulations. In addition, a building fire well and hose reels have been installed. The hoses are capable of reaching the entire tipping floor areas. 8 • TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT 2.2 Compost Facility Description of Operations The Town of Southold has operated a compost facility since 2001 on 17.2 acres on the west side 40 of this site. Due to the fact that an extensive engineering report has been previously prepared by the H2M Group for the compost facility, please see the attached report entitled Engineering Report dated November 2001 — Yard Waste Compost Facili"repared by H2M Group which is attached as Appendix A of this document for a detailed description of the operations of this facility. • For convenience, a brief overview of the process undertaken by the town to compost yard waste materials is described below: • • Compost Site Incoming Materials • Residents and Landscapers after weighing in at the scales are directed to the compost area within the site to unload leaves and brush. Wood and leaves are handled separately at the site. • Compost Site Processing Wood and leaves are handled separately at the site. Wood is ground up in the town's CBI • grinder; wood includes brush, pallets and other clean wood. Leaves are placed into rows in order to form windrows using a payloader. Wood/brush first receives a primary grind using a 6 inch demolition screen. The resulting sized reduced wood is then screened in a McCloskey trommel equipped with %2 inch screens. The smaller sized pieces of wood that fall through the screen openings (about 25% of the total) is marketed by the town as • screened woodchips suitable for landscaping or erosion control purposes. The oversized pieces of wood that don't fall through the screens (about 75% of the total) are placed in the CBI grinder for a second grind, but this time using a smaller 2 inch screen. This material is marketed as double ground wood mulch. Leaves are windrowed for 49 approximately 8 months until ready for final screening using a 3/8 inch opening in the screen. Any oversized yard waste materials left is placed back in the windrows for further processing. :7 • Compost Site Products The Town markets four (4) types of products generated by its composting operations: E • TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT 1) single ground woodchips, i.e., "Rough Cut" woodchips made from the primary grinding of brush. There is a limited demand for the product, but it is sometimes requested for use on nature trails or as ground cover on newly cleared land. Because these woodchips would otherwise need to be screened and reground to in order to market, the town makes them available free of charge. 2) screened woodchips which consist of the fines resulting from the initial trommelling of the single ground material 3) double ground woodchips which are screened woodchips after a second grinding using the 2" screens; and 4) leaf compost which is the final fully decomposed leaf material for use as a soil amendment for farmers, landscapers and gardeners. The screened and double ground woodchips, as well as the leaf compost are marketed through the "free residential mulch program" wherein town residents may take up to 50 pounds per residence per year for free, or for a price to commercial users and to residents taking more then 50 pounds. 2.3 C&D Area Description of Operations • Background Until 1993, C&D debris accepted by the Town was processed and buried in the unlined Cutchogue landfill. When the landfill was closed in October of that year, the Town began to transfer its C&D stream to out of town facilities. Wanting to focus its efforts on handling and transferring MSW for its residents (since there was no alternate approved MSW transfer station in the Town), the Town sought to reduce the C&D waste stream under its management by implementing a tip fee on C&D far higher than that charged at private transfer stations on Long Island or the Brookhaven landfill. This had the desired effect, as the roughly 10,000 tons per year the Town accepted when it was landfilled fell to around 3,000 tons per year as the private market took over hauling and disposing of most of the C&D generated within the Town. Receipt and transfer by the Town of this reduced waste stream first came under DEC registration in 1997, at which time operations occurred on top of the closed, but not yet capped, landfill. Registration of this activity was approved only until such time as capping of the landfill was to begin. After approval of the Town's Landfill Closure Plan in 1999, which called for the importation of thousands of yards of material for landfill grading and contouring, the Town petitioned and the DEC approved the continued acceptance of locally generated C&D only for use as grading material under the cap. This continued until December of 2003 when the Town received a re -registration for C&D transfer at a point outside the footprint of the landfill. This 2003 registration is still in effect today. 10 TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT • Amount (Tipping Fees) The Town still charges a higher -than -market -rate tip fee for C&D, and as such it still manages only a small portion of the stream generated within the Town. In 2013, the • Town accepted approximately 1,800 tons of C&D at the transfer station. Most of this debris is generated by small contractors or "do it yourself' homeowners delivering in pickup trucks. Larger, "commercial" amounts of debris collected and hauled in roll -off containers are removed by private haulers to out of town facilities, where disposal fees II!I • are charged by volume (as opposed to weight at the Town facility). • Procedures Users enter the facility via the same roads and scale facility as described above. After weigh in most users bring their debris to an outdoor concrete bunker, 40'x50' in area, located between the scale and the transfer station building for unloading. The area is clearly visible from the scale for users to see. After enough debris has accumulated there for at least 1 trailer load, a CEO in a front-end loader will load a trailer parked on the • ramp of the transfer -trailer pit inside the building. This ramp is actually outside on the west -facing side of the building, approximately 150 feet away from the C&D bunker, however loading in this manner instead of inside the building (with the trailer fully in the "pit") is preferable as it avoids completely any interaction between the loading operation and users of the building, and eliminates dust or debris from the building. The C&D • bunker has a holding capacity of 500 cubic yards. Users with large pickup loads, small trailers, and the occasional roll -off box do NOT use the C&D bunker adjacent to the building, but instead are directed to a larger concrete • bunker in the facility's former borrow pit (i.e., area once mined for sand for covering waste when the Southold landfill was active). This bunker is approximately '/ mile to the north of the scale facility, quite remote from any other activity occurring at the site. It is 80' x 50' in size and can hold up to 800 cubic yards of debris comfortably. Adjacent to the bunker is a 100'x60' blacktop pad leading up to a 6' high loading wall at one end. • When ready to transfer C&D from this bunker, an operator will place a trailer along the • loading wall and load debris using a front-end loader. The Town loaded a total of 141 100 -cu yd trailers with C&D in 2013. 11 i TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT i 2.4 Landfill Area The Town of Southold initiated operations in the landfill site in 1920 for the disposal of solid waste, refuse debris and scavenger (system) waste and operated the landfill continuously until 1993 when it was closed. The closed landfill property is approximately 34 acres. Due to the fact that an extensive post closure engineering report has been previously prepared by the for the landfill facility, please see the attached Post -Closure Monitoring and Maintenance Manual for Southold Landfill, dated August 2003, prepared by Dvirka and Bartilluci attached as Appendix B of this document for detailed information concerning landfill closure activities. 2.5 Facility Wide Issues 2.5.1 Normal Traffic Flow This section of the engineering report discusses traffic flow issues during both normal and peak periods. Waste vehicles enter the facility's access road located on Cox Lane which is several hundred yards north off the Middle Country Road (Route 48). Almost all vehicles will use Middle Country Road to access Cox Lane for the entry and exiting i of the facility. Generally, three types of vehicles enter and exit this solid waste complex that could impact traffic, namely: 1. Residential and commercial garbage (Packer Trucks) 2. Homeowners (residents) delivering waste and recyclables in their cars 3. Homeowners/Landscapers delivering yard waste 4. Homeowners/Contractors hauling C&D waste i 5. MSW Transport Contractor (Trinity Transportation working as a subcontractor to Progressive Waste, Inc.) hauling MSW waste from site for disposal out of town. 6. C&D Transport Contractor (Trinity Transportation working as a subcontractor to Progressive Waste, Inc.) hauling C&D waste from site 'i for disposal out of town. 12 TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT 7. Recyclables Hauling Contractor (Trinity Transportation working as a subcontractor to Progressive Waste, Inc.) hauling recyclables from site for disposal out of town. In 2013, some 75,000 vehicles entered and exited Southold Solid Waste Management Facility. The facility experienced approximately 651 vehicles delivering waste to the site on an average day. Similarly, the facility experienced an estimated 1142 vehicles per day during peak periods in the spring during the Towns spring cleanup period. The hours of operation for this facility are from 7:00 AM to 5:00 PM allowing for a ten hour working day. Hence, the average traffic in an out of the facility is approximately 65 vehicles an hour during normal operating periods and 114 vehicles an hour during busier peak periods. The Town of Southold's Solid Waste management Facility is located in an area that is still rural in nature when compared to the rest of Long Island and as such its roadway network in the vicinity of this facility experiences a low traffic volume. Accordingly, it is felt that the site contribution of 65 vehicles an hour on most days and a higher contribution of 114 on peak days will not adversely impact local traffic. Also, it should be noted that peak traffic at the facility occurs in the spring and not during the busier summer period when road traffic is heavier due to the influx of tourist visitors to the town. Vehicular traffic from the site has never backed out onto Cox Lane causing a traffic problem. This is due to the long (approx. 1,000 feet) entry/service road to scales for vehicle queuing and the moderate vehicle traffic generated at this site. 2.5.2. On Site Heavy Equipment Heavy equipment utilized on site to handle the solid waste received is as follows: 0 • One Caterpillar 966 Payloader • One Volvo L120 Payloader • One McCloskey 21 foot Trommel Screen • One CBI 3000 Grinder 0 • One Caterpillar Articulating Dump Truck • One Ford LTS 9000 Yard Horse 0 13 TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT • One Forklift The Volvo payloader is utilized to move and stockpile the waste within the transfer building and at the C&D site. The Caterpiller 966 payloader is used to support operations at the compost facility including windrow turning. The McCloskey trommel screen is also used in the processing of yard waste materials as well as the CBI grinder. The dump truck, yard horse and forklift are used for general site work as dictated by site conditions. 2.5.3 Financial Assurances If the NYSDEC decides after review of this application that a form of financial assurance will be required to secure payment closure and any remediation activities, the Town of Southold will then provide the necessary documentation once the specific amounts are determined and requested by the NYSDEC. The Town of Southold Solid Waste Management Complex is owned and operated by the Town, a municipal corporation. Should any financial assurance be required 40 by the Department, the Town intends to pledge its full faith and credit and statutory authority to levy and collect taxes as the form of financial guarantee.

Liquid wastes b. Household Hazardous Waste c. Medical waste d. Radioactive wastes e. Sewage or Sewage Sludges f. Contaminated Soils g. Unauthorized Waste The C&D transfer station receives only construction and demolition debris and does not accept residential or commercial waste nor waste types a. through j. above. The Compost Facility receives only yard waste consisting of leaves brush, clean wood such as • pallets) and grass; it does not at this time receive any other form of organic waste, such as food waste. The Landfill Facility was closed in 1993 and accordingly does not receive any type of waste for • disposal. The landfill has been capped in accordance with DEC Part 360 regulations and is now a dormant site. Unauthorized Waste shall mean liquid wastes, sludge's, asbestos, infectious waste, other hazardous wastes and other such material that are not permitted at the facility. Employees • working in active waste areas of the site are trained in identification of unauthorized wastes and potentially hazardous materials that may be encountered. Should a hazardous waste be identified within the confines of the facility, it will be containerized, secured and separated from the other solid wastes on site as per Part 360-16.3(h)(4)(I)c. The isolated waste will be recorded � and included in the annual report and stored no longer than 90 days upon discovery. All unauthorized waste removed from the Facility shall be accompanied by a tracking document and be handled/transported by authorized personal only. The Supervisor will retain a 6NYCRR Part 364 permitted transporter to properly remove and dispose of the material. • A written report will be submitted to the Department with five (5) business days. The correspondence will be directed to: 0 17 I0 I0 TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT Regional Solid Waste Engineer New York State Department of Environmental Conservation SUNY @ Stony Brook 50 Circle Road Stony Brook, NY 11790-2356 Should a load of waste be identified as one of the above, the driver will be instructed to not unload his vehicle. As each delivery vehicle is identified at the scale house, a notation will be made and the generator of the waste along with the Regional Solid Waste Engineer will be contacted. Infractions against the firm could result in loss of facility use privileges. The plan for detecting and preventing the disposal of hazardous wastes at the facility will be comprised of the following components: • Random inspections of incoming loads • Inspections of suspicious loads • Recording inspections and keeping a paper trail Random inspections of incoming waste • In addition to waste acceptance screening and training program requirements, the facility will conduct periodic random inspection of incoming waste loads. Random inspections are yet another mechanism to ensure the effectiveness of a waste acceptance screening program. The inspections will be conducted at least bi-weekly and occur on the tipping floor. A record of the inspection will be completed and maintained on file at the facility. Procedures for conducting the random inspections will include: • Designation of a separate and exclusive area • Provide protective clothing and equipment (rakes and shovels) for inspection personnel • Maintain removal equipment on hand to isolate waste if necessary • Establish pre -planned methods for containment, transport or disposal of unauthorized materials • Conduct decontamination procedures for the inspection site, personnel and equipment 'i' 0 18 • TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT Inspections of suspicious loads As part of selecting waste loads for inspection, the Facility Manager will consider the • type and source of wastes generated within a service area and/ or the type of hauler involved, assurance that any one hauler can be checked at anytime, and an ability to promptly check loads deemed suspicious. The Facility Manager will be required to: • Know the waste sources Ilj • • Maintain an updated customer file of Waste Transporter Permits • Require specific quality control of incoming waste • Know waste haulers • Train landfill personnel j • • Check random loads bi-weekly • Be prepared to take corrective action to exclude prohibited wastes Recording inspections and keeping a paper trail The Facility Manager will maintain records of any prohibited waste delivery event and records of random load inspections. The Facility will achieve compliance with this • requirement by documenting each inspection, as well as each incident whereby an unauthorized waste is detected. Information will be recorded on pre -developed inspection report forms which will facilitate documentation of the following: • • Date and time of material detection • Hauler name, company and driver • Name of inspecting personnel • • Description of the inspection procedure and equipment used • Material(s) detected • Material generator(s) if identified • Corrective action(s) taken to segregate, contain or remove unauthorized wastes • Efforts taken if extreme toxicity or hazard was discovered • Necessary agency notifications utilizing telephone conversation record sheets j(b 19 • TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT Records of unauthorized waste discovery and random load inspection activities will be maintained by the Facility Manager for a minimum period of seven (7) years from the date of discovery or inspection. These events will also be summarized in the annual report to the NYSDEC.

Island Pump and Tank Inc. - 40 Doyle Court, E. Northport 11731, (631.462.2226) or an approved, comparable alternate will be retained to be available on a twenty-four (24) hour basis to respond to hazardous waste/material incidents. 5.3 Equipment Breakdown In the event of equipment malfunction, several alternatives are available depending on the magnitude of the malfunction. The following actions listed for each machine to be operated at the facility are prioritized; that is, the first recourse listed is the first action to be attempted. Should a certain action be inadequate to address the malfunction, the next action listed will be attempted. The following actions will be taken, as appropriate, to remedy the equipment malfunction: • troubleshoot and repair • use alternate equipment • rent alternate equipment • bypass the affected operation In the event of facility shutdown, residents and carters will not be permitted to deposit waste at this facility. 5.4 Fires Operators will be alert for signs of burning waste such as smoke, steam, or heat being released from incoming waste loads. Smoking is not permitted near waste management areas. In the case of the main MSW transfer station building, fire extinguishers will be strategically located throughout the tipping floor area. All fire extinguishers are capable of fighting class A, B and C fires as defined by Underwriters Laboratories. Fire detection systems are in accordance with 29 CFR 1910.164 and applicable local rules and regulations. In addition, a building fire well and hose reels have been installed. The hoses are capable of reaching the entire tipping floor areas. The Compost facility is equipped with a large 500 gpm water supply well that can be used to fight fires in addition to the site's water truck. Heavy equipment can also be brought in to smother any hot spots ofor flare ups. • 23 TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT In regards to the C&D area, should a fire occur in this relatively small isolated area, heavy equipment can be used to extinguish any fires with the assistance of the water truck and fire extinguishers. � • 5.5 Site Security The site is secured by a chain link fence and berm. At the close of business hours or when no attendant is on duty, all doors and gates are secured and locked to prevent unauthorized access and possible subsequent injury to personnel and to preclude illegal dumping. 5.6 Emergency Services - Site Evacuation In the event that the emergency response gear maintained at the facility is inadequate for the task at hand and the nature of the emergency is such that there is a real and present risk of injury to the site personnel, the site will be evacuated. Appropriate agencies, specifically the Police and Fire Department, shall be immediately notified of such a decision so than any dangers to the public at large may be promptly and adequately assessed. The senior person at the site will make the decision to evacuate the site and will, at that time, indicate his decision by verbally notifying all personnel. Personnel will assemble in pre -designated assembly areas coordinated with the Fire Department. Roll calls will be performed at the assembly areas so that all personnel are accounted for. 5.7 Noise The project site is zoned for light industry (LI). As such there are not many residential homes in the vicinity of this site. In reference to the Residential/Commercial Transfer Station Facility, all loading and unloading operations are conducted within the building reducing the potential for noise impacts. A combination of building materials, construction and landscaping features further mitigate noise impacts. The only source of noise at this facility would be from internal combustion engines (i.e. Payloaders, trucks). Sound levels for such equipment must not exceed 80 decibels (A) at a distance of 50 feet from the operating equipment. If a piece of equipment exceeds this value it will be removed from the site and replaced. If a waste carter's vehicle is exceeding the 80 decibels, then that vehicle will be prohibited from coming to the site until the noise specification can be met. In the event that noise levels exceed Part 360 guidelines, remediation measures will be instituted. 24 • TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT Excessive noise has not been an issue for the Composting Facility due to the fact that the site is in a low lying area which shields surrounding neighbors from noise. Also the Town has left a land buffer on the south east side of the compost area to protect the homes in the Tuthill Lane area from any potential noise impacts. Additionally, the compost • facilities brush/wood grinder has been relocated to the north end of the site to increase the buffer distance to the homes in the Tuthill Lane area. Similarly, excessive noise from the C&D Processing Area has not been an issue at this site due to its relatively remote location on the property, with the nearest residential • neighbor being more than a quarter mile away. This is also a relatively small size transfer station receiving only 1,850 tons of C&D waste in 2013 for an average of approximately 6 tons per day. This small receiving rate helps in keeping noise impacts to a minimum. There has been no noise complaints registered against any of the above the facilities in the last five (5) years. • 5.8 Dust In order to control dust inside the main Transfer Station Facility, the Facility Operator shall suppress the dust with water from water hoses located in the building. The hoses III • are capable of reaching the entire C&D tipping floor areas. Other sources of dust also include vehicular traffic on unpaved areas. Mostly, all portions of the site dealing with vehicular traffic are paved. This minimizes generation of dust from vehicular traffic. The Town also owns a water truck equipped with spray bars which can be deployed in dusty conditions to wet down road surfaces to further mitigate against dusty conditions. In reference to the closed landfill areas, as the landfill have been caped and planted with a vigorous vegetative cover, dust emissions should be negligible from these areas of the site. Lastly, dust can potentially be generated by the compost operations on the west side of the site, i. e., windrow turning, grinding operations and truck movements as an example. • Even though dust impacts from the compost operations historically have not been a problem, remedial steps will be taken if dusts problems occur. These remedial measures 0 25 TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT includes wetting down the working areas with water or dust palliatives and/or temporarily stopping operations until more favorable wind conditions exist. In addition to the water truck the, Town has installed in several strategic locations, water sprinklers and water "bazookas" to further suppress dust should the need arise. There is a 500 gpm water supply well in the compost area to provide water for dust control as well as to S provide water for the windrows to facilitate composting. There has been no dust complaints registered against the facility in the last five (5) years. 0 5.9 Vectors Vectors such as flies, rodents, and birds are associated with municipal solid waste. By removing all of the MSW from the main transfer station building on a regular basis the vector attraction to the site is minimized. All waste receiving and handling activities are conducted inside the steel building which is erected above a concrete floor The nuisance vectors described above are not expected to be problematic at the C&D transfer area or the compost site as no putrescible waste is handled at these locations as there are no food sources for vectors. Lastly, since the old landfill has been closed and capped, access to any waste attractive to vectors has been sealed off and not accessible to them. Should it become necessary, a professional exterminator will be utilized to provide a rodent control plan that includes bait boxes and traps. 5.10 Birds & Litter • All vehicles delivering waste to the facility are required to have their vehicles either tarped or enclosed to eliminate litter. The manned scale house is utilized for vehicle inspections. If a vehicle with an open load enters the facility, the vehicle driver is instructed to exit the site. I• The Facility Operator shall control litter from the Transfer Station Facility by deploying a laborer responsible for policing the entire site for fugitive litter. The laborer shall have personal protective equipment and containers (bags or garbage pails) to safely handle and dispose of the litter. The existing fencing that surrounds the site will also assist in minimizing litter from blowing off-site. 26 TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT Daily policing of the grounds is conducted to remove any papers and litter which may have collected. This further reduces bird attractions. Seagull deterrent wires have been used successfully at other sites and can be considered in the event that birds prove to be a problem. • To minimize rodent and insect attraction, waste activities are conducted indoors. The tipping floor is cleared on a daily basis. As rodents and insects may be present in waste loads entering the facility, a professional exterminator will be utilized to provide a rodent control plan that includes bait boxes and traps when necessary. 5.11 Odors To minimize impacts on the general public related to odor generation, the main MSW Transfer Station building incorporates mitigation features. All receipt, storage and load out of waste is conducted indoors. Good housekeeping practices are maintained A throughout to minimize the generation of adverse odors. Spray atomizers, if required could be utilized. After waste is received, it is loaded into long haul tractor trailers for transfer to out of state solid waste disposal facilities with 24 hours. In the event that wet suppression techniques fail to control air pollution or odors, an odor counteractant stray f atomizer system can be installed. The preferred vendor for an atomization system if required will be Hilsilblon Inc, an air pollution company whose spray system has established a good track record in solving odor problems at other transfer stations here in New York. J As the C&D area will not receive putrescible waste, odors are not anticipated to be a problem in the community. The closed landfill is not expected to generate odors as it has been capped by a impervious geomembrane encapsulating and sealing off any odorous materials. In regards to the Composting Facility, odor control at the facility will be accomplished through a combination of best management practices, site drainage and pro -active odor monitoring. Best management practices include proper construction and maintenance of 40 windows to ensure maximum aeration and elimination of odor causing conditions. Site drainage will direct runoff from the windrow to the south and west away from the nearest 27 TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT neighbors that may be affected by odors form standing water. In addition, on-site drainage into the soil will eliminate water and any runoff from the construction of drainage swales. Acceptance of grass has been prohibited at this facility which has been considerable help in eliminating compost odors. The location if the site is also advantageous with respect to minimizing odor impacts due to the fact that the nearest • residences are located south of the site and the prevailing winds at the site are from the southwest. There have been no odor complaints from this site for over five years since 2009. 5.12 Unusual Traffic Conditions In the event that the site is faced with unusually heavy traffic conditions, the waste • delivery trucks will be directed to stack on the entrance road to the facility. There is sufficient stacking length for over twenty (40) vehicles behind the entrance gate. Under no circumstances will the facility operate above capacity or allow waste to exit the building footprint. Trucks/cars can also be turned away in the event of unusually traffic conditions. 5.13 Safety and Training Plan It is the responsibility of management to provide a safe working environment for the employees of the company. Safety awareness is highly dependent upon the attitude of the manager and supervisors. The ultimate goal of the company is to make safe practices such a habit that no conscious thought is needed to maintain these practices. All precautions taken to safeguard the employee's health and welfare shall be, at a minimum, in accordance with 29 CFR Parts 1900 through 1910, inclusive, and any applicable local rules and regulations. Copies of such regulations are maintained at the site and made available for employee review. Copies of 29 CFR Parts 1900 through 1910 may be obtained through the United States Government Printing office, Phone: 202-783-3238. Protective equipment for personnel at the site includes, but is not limited to: • respirators as required by 29 CFR 1910.134 • safety boots, shoes as required by 29 CFR 1910.136 0 28 TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT • hard hats as required by 29 CFR 1910-135 • safety glasses, goggles as required by 29 CFR 1910.151(c) • gloves as required by 29 CFR 1910/156(c) • face shields -as required by 29 CFR 1910.133 • emergency stop switches for machinery as required by 29 CFR 1910.216(e) • hearing protection as required by 29 CFR 1910.95(c). • fire extinguishers and fire hoses are located in the building. 5.14 General Employee Training Any process that increases the skills and abilities of the employees to do a specific job is referred to as "training". Training is usually distinguished from "education" as the process of increasing ones understanding. Obviously, there are overlaps between the two processes. All employees will need to demonstrate that, at a minimum, they can read English. Without this basic skill, training an employee and safeguarding their health and welfare is difficult. It will be the responsibility of the Facility Manager to assure that all personnel know how to perform in a manner that will promote the establishment and maintenance of a safe working environment. Training will be an ongoing process. Institution of new techniques or modification of procedures will be accompanied by careful consideration of the training required to perform safely. All personnel will be adequately trained to safely carry out their designated on site duties. M Training of personnel will be both intramural and extramural. Intramural training will be provided on the job and may range from working closely with a person familiar with the facility operations and safety requirements to formally structured classes with lectures and presentations. Specifically, intramural training will cover and instruct employees in the following areas: • the facility layout specifically the location of exits, first aid and safety equipment • the correct use of safety equipment, including, but not limited to, gloves, masks, eye protection and safety boots • the site contingency plan • specific workplace practices - specifically: 29 TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT a. hand washing b. handling of sharp objects C. routine examinations of equipment d. disposal of contaminated materials e. decontamination and cleaning of equipment and machinery £ the correct and safe operation of all on site fire fighting equipment g. procedure for reporting safety violations • 0 I0 • • 30 • TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT • 6.0 Closure Plan The closure activities for the landfill and compost facility are described in the reports below.

The details presented below apply to both transfer station facilities 6.1 Transfer Station Closure Procedures At the cessation of site operations all waste will be removed and appropriately disposed. • The site will be fully secured to preclude potential illegal dumping. The closing of the facility is not anticipated to cause any adverse effect on the surrounding community. Any buildups of residues and or staining will be removed by scraping, digging and or steam cleaning. Collected contaminated materials will be contained for appropriate • removal and disposal. Any remaining residue MSW or C&D waste left will be removed and transported offsite for final disposal at a NYSDEC approved disposal facility. The transfer stations left in a "broom clean" condition. Found vectors will be appropriately treated and removed from the site. Similarly, any remaining litter will be collected from the transfer station and surrounding areas. 6.2 NYSDEC Notification of Closure • At the end of the site investigations and subsequent cleanup, the NYSDEC will be notified in writing of the intended closing of the facility. Said notice will be sent to the NYSDEC at least thirty (30) days prior to said closing. The NYSDEC, or an agent acceptable to said agency, will then arrange to inspect the site to complete the closure or • to determine any additional efforts that may be required to complete the closure. All 31 • TOWN OF SOUTHOLD SOLID WASTE MANAGEMENT FACILITY ENGINEERING REPORT . work performed at the site shall be performed in a manner acceptable and suitable to the NYSDEC and any applicable local rules and regulations 6.3 Financial Assurances If the NYSDEC decides after review of this application that a form of financial assurance will be required to secure payment closure and any remediation activities, the Town of Brookhaven will then provide the necessary documentation once the specific • amounts are determined and requested by the NYSDEC. The Town of Brookhaven Solid Waste Management Complex is owned by the Town, a municipal corporation. Should any financial assurance be required by the I1 I• Department, the Town intends to pledge its full faith and credit and statutory authority to levy and collect taxes as the form of financial guarantee. 32 I• u I• rl 40 TOWN OF SOUTHOLD SOLID WASTE DISTRICT YARD WASTE COMPOSTING FACILITY 6 NYCRR PART 3601 ENGINEERING REPORT NOVEMBER 2001 On '•�ELd•'•f� V2/4(-;ADPP PERMIT TO CONSTRUCT A YARD WASTE COMPOSTING FACILITY ENGINEERING REPORT TABLE OF CONTENTS PAGE NO.

The Town proposes to locate a yard waste compost facility at a 17.22 acre site on Middle Road (County Road 48) in the Hamlet of Cutchogue. The site is identified in The County of Suffolk Tax Maps as District 1000, Section 96, Block 01, Lot 02. Development of the Facility, in accordance with 6 NYCRR Part • 360 regulations dated November 24, 1999, supports the efforts of the town to implement an integrated solid waste management program that combines waste -to -energy with recycling, waste reduction and landfilling in conformance with the New York State Solid Waste • Management Plan 1988/1989 Update. The Town of Southold is facing a waste disposal crisis as landfills continue to fill up and the disposal capacity is not replaced. The Town is currently developing several alternatives to avert the crisis and is in the process of capping its Iandfill, As part of the Town's overall waste management strategy, yard waste composting offers a viable alternative by eliminating such waste from the landfill -bound wastestream and converting it into a useful and marketable • product. At present, yard waste within the Town of Southold is transported to the Cutchogue Landfill for processing and for disposal. A portion of the northwest property line of the proposed site is contiguous with the south property line of the Cuthogue Landfill. This site was selected on the basis of ease of access, existing availability of utilities, traffic patterns, existing land use, maximum buffer, minimal environmental impact, land availability, drainage control and access to existing facilities at the Cutchogue Landfill. The site is to be constructed with adequate access roads, substructure soil stability and drainage control to provide for a permanent facility. The facility will accept yard waste from sources within the Town of Southold and will accept yard waste from the Town of Huntington based on an intermunicipal agreement. 0 LI Municipal waste collected routinely from households includes a heterogeneous mixture of glass, plastic, metal, ceramic, leather, paper, cardboard, food waste, and yard waste (leaves, grass clippings, small branches and wood chips). Leaves differ from the rest of the wastestream in that they occur seasonally and are easier to segregate from the overall wastestream. In season, leaves may account for up to 50 percent (by volume) of the municipal waste collected. On a yearly basis, leaves may account for 2 to 20 percent of the total municipal solid waste (MSW) collected. These values depend on factors such as land use, population and character (urban, suburban or rural) of a community. Because segregated leaf waste is homogeneous, seasonal, and organic in nature, it lends itself to treatment by relatively uncomplicated composting procedures. The end product of the process is compost, which can serve as an organic amendment for soil or be utilized as a supplement to landfill cover material. Composting is a biological process in which organic matter is broken down under aerobic and thermophilic conditions into a humus -type end product. The composting process is dependent upon biological and environmental factors, including the population of •' microorganisms, the carbon -nitrogen content of the substrate material, temperature, oxygen concentration, moisture and pH. Composting is used to decompose the organic materials in tmunicipal solid waste sewage sludge, agricultural wastes, industrial wastes and yard wastes. The properties of the end product, known as "compost," make it useful as a soil conditioner, Composting has been identified by the New York State Department of Environmental Conservation (NYSDEC) as an acceptable form of recycling. The Town of Southold is committed to the integration of yard waste composting as a valuable component of the Town's comprehensive recycling program. 2 I• J • J 2.0 STATEMENT OF COMPLIANCE WITH THE GOALS AND OBJECTIVES OF THE NEW YORK STATE SOLID WASTE MANAGEMENT PLAN The Town of Southold's proposed yard waste compost facility is compatible with the objectives of the New York State Solid Waste Management Plan. To promote integrated solid waste management. the plan advances a "solid waste management method hierarchy," or order of'preference. This order is as follows: [haste Reduction Recycling and Reuse r Kiste-to-Energy and Landfilling By implementing a yard waste composting operation, the Town will be recycling the yard waste material which may otherwise be disposed of in a landfill. The end product of the composting process is compost, which is a soil conditioning material and, when used as such, is considered a recycled material. The recovery and reuse of such recyclable material will (1) reduce the consumption of and the demand for scarce landfill capacity, and (2) aid in the conservation of vital natural resources and energy. In making use of an otherwise unusable waste, yard waste composting furthers the State's goal to reduce reliance on landfilling. Finally, when properly operated a composting process will not produce a discharge or release to air or water. This asset, while not specifically addressed under the guise of solid waste management, furthers the goals and objectives of all environmental legislation whose fundamental purpose is to provide a safe and healthy environment for future generations. 3 3.0 PLANS 3.1 Regional Man Located in the Hamlet of Cutchogue, the proposed site is north of Middle Road (CR 48), approximately 0.15 of a mile east of Depot Lane and 0.11 of a mile west of the Cutchogue Landfill entrance. A regional map (scale 1:62,500) has been provided in Appendix 1 that delineates (shaded portion) the entire service area of the proposed composting facility. The regional map identifies the proposed and existing collection, processing and disposal operations, the major transportation systems in the area, including highways, airports, railways, ferry routes, and the closest population centers. 3.2 Site Vicinity Man The proposed site area is located between Depot Lane to the west and the Cutchogue Landfill to the east as shown in Appendix 2. The site is approximately 720 feet east of Depot Lane and includes a 420 foot frontage on Middle Road (CR 48). A vicinity map (scale 1:24,000) has been provided in Appendix 2 that delineates the • project area within one mile of the proposed facilities boundaries. Depicted on this map are local surface waters, residences, access roads, railroads, airports and any historic sites. 3.3 Site Plan The facility site plan and grading plan is provided in Appendix 3, which details the site in its relation to the Cutchogue Landfill complex. The grading plan (scale 1:1200) depicts two foot topographic contours, existing roads and utilities. The grading plan also shows the locations of any soil borings, monitoring wells, gates, parking areas, drainage, culverts, storage facilities, loading areas , surface water -bodies and ' drainage swales on the proposed site. 01 F'11 4 The site plan details the anticipated locations within the site facility of the bagged leaf storage area, shredding and grinding area, screening area, compost storage area, and windrow pile area along with optional areas for future storage buildings. 3.4 Auxiliary Plans Any wetlands and/or floodplains located within a 1,000 foot radius of the site are detailed in Appendix 3, Detailed information concerning land use, zoning. community facilities and a 0 geological cross section of the area surrounding the facility are shown on plans located in Appendices 4 through 7. 4.0 DESCRIPTION OF THE ULTIMATE USE FOR THE FINISHED COMPOST • A Final Marketing/Utilization Plan (Plan) of the processed compost cannot be defined until the material is actually produced, analyzed and evaluated for local growing conditions. Before the Plan will be finalized, any and all local, State and Federal requirements for compost end -products and particular uses will be met. The Plan will include a description of the labeling or other information necessary to specify the sources of waste from which the compost is derived, restrictions on usage, and suggested application rates. Initially, it is intended that the finished compost will be made available to local retail and residential users for gardening and soil enrichment purposes. It is also expected that finished compost will be used by the Town Parks and Highway Department in public projects to create natural berms and to improve water retention properties of the soil. Since the production of compost material by the yard waste composting facility is not expected to exceed the need for retail and town department purposes, there will not be a surplus of compost finished product at the site. The NYSDEC has already approved the use of the Cutchogue Landfill as a Brush Processing Site based on a registration validation letter from NYSDEC dated September 4, 2001 and has been included in Appendix 8. The facility will be designed with the flexibility to accept mechanical equipment capable of producing a high quality compost. The cost-effectiveness of 5 I10 providing this additional equipment for producing high quality compost for sale to agricultural or horticultural markets will be studied by the Town at a later date. 4.1 Case Histories There are numerous yard waste composting facilities operating successfully in the United States at the present time. In the Tri-state area (New Jersey -New York -Connecticut), yard waste composting operations are experiencing success in marketing the compost to various users. A "market" for composted yard waste may be defined as a productive use for the material which would divert it from disposal. Users may pay for the compost, but this is not a necessary criteria for a successful marketing program. Tenafly, New Jersey has been composting leaves for thirty years. They also make wood waste available to residents in the form of firewood and wood chips at no charge. Two products are distributed, a shredded product which sells for $10.00 per cubic yard, and an unshredded product which sells for $6.00 per cubic yard. These prices are for commercial businesses such as nurseries and garden centers. Residents are allowed to pickup material free of charge. Early in the program, the product was sold at $5.00 per cubic yard and supply was exhausted in a short time. Subsequently, the Town Council raised the price in order to have more material available for residents. In Webster Groves, Missouri residents annually pickup 1,200 cubic yards of compost from stockpiles that the City maintains in several municipal parks. There is no fee for the material. The City applies 3,500 cubic yards annually to its parklands. The Missouri Botanical Gardens uses approximately 500 yards per year. Other special, one-time projects consume significant quantities. The "Town of Wellesley, Massachusetts produces approximately 5,000 to 8,000 cubic yards per year of material used by the Town in municipal projects. During 1999, Wellesley sold 10,000 cubic yards of composted leaves to a nursery for a credit of $2,350 worth of plant material. Topsoil, which costs $8.00 to $10.00 per cubic yard, is no longer purchased for municipal projects. The public is allowed to take compost at no charge. 0 I0 Greenwich, Connecticut composts leaf and yard waste with sewage sludge by the static • pile method. Over 4,000 cubic yards of material are distributed annually with approximately 20 percent used in municipal projects, 20 percent used by residents and 60 percent sold to landscapers. The City allows residents to pickup the material at no charge and receive $7.00 to $9.00 per cubic yard from commercial landscapers. City officials estimate that several hundred individuals have used the compost product over the years. Since the material contains sewage sludge, the City analyzes the product for heavy metals and pathogens on a regular basis. ` Midland, Michigan has been operating a leaf composting operation since 1968. The product has been used in a variety of municipal projects, including the preparation of landfill cover material. It is also blended with soil to prepare topsoil for landscaping public parks. The finished compost is available to the public and to buildings, cemeteries and highways. • professional users at no charge in bulk form. City officials estimate saving $37,000 per year in topsoil purchases. Topsoil sells for $5.00 per yard. At LaPere, Michigan approximately 2,000 to 3,000 cubic yards of compost are distributed annually. The City has not assigned a value to the product which is used entirely in municipal projects such as parks and cemeteries. • One of the few composting operations that delivers compost to end users in Hennepin County, Minnesota. Approximately 35 commercial landscapers and five nurseries receive the material at no charge. Officials estimate that 40 percent of the material is distributed in this way. Private residents pickup and use approximately 50 percent of the material produced. The • remaining product is used by the municipalities. Total annual distribution is approximately 20,000 to 30,000 cubic yards. Two of the larger and more sophisticated leaf and yard waste composting operations in • the country are in California. The City of Davis operates its own facility, while in Berkeley a private firm called Urban Ore, Inc. is used to operate the compost facility. • 7 u i• � ' At Davis, woody yard waste is ground and added to leaves and grass clippings to under o g composting. The high quality product is reground before distribution to create an even textured material. Due to the size constraints at the site, some material that is only partially decomposed ' is sold as mulch material. Other incompletely degraded material is dried and sold as boiler fuel. The City has found its primary markets to be local landscapers and nurseries. These users substitute the composted wastes for processed forest waste materials. However seasonal variation in materials received at the compost site results in variable products, thus limiting the value of the material to professional users who desire a consistent product. Approximately 25 percent of the compost produced is given free to residents for use in private gardens. The ' average price that Davis receives from commercial buyers is approximately $4.00 per cubic yard or $20.00 per ton. This is their breakeven cost. Urban Ore, Inc. has marketed its compost products primarily to homeowners and private landscape firms. Composts and mulches were sold primarily to the same landscape contractors who brought in the brush. Urban Ore also sold directly to homeowners, renters and property ' managers. Small quantities of bagged materials were kept on hand for these smaller users. Material that was delivered in bulk was hauled by independent truckers. Brookside Nurseries, Inc. of Darien, Connecticut provides complete leaf composting services to municipalities in Connecticut, New York, and New Jersey. Brookside's operations are unique in that the leaf compost is blended with other waste organics and inorganic materials ' to create more than 20 different soil amending products, mulches and soil substitutes. It has been the experience of Brookside that professional horticultural tradespeople do not want leaf compost per se. Where they do purchase leaf compost, they are blending it with other materials. Thus, the creation of the various specialty products from a leaf mold base is tilling a well-defined need. The Town of Islip, New York currently operates a 100,000 cubic yard per year yard waste composting facility. The demand for compost for public landscaping projects at Town ' facilities such as parks, ball fields, buildings, traffic islands, golf courses, beaches, road shoulders, landfill cover, etc., has exceeded the production to date. The Town anticipates that *I any excess compost material will be made available to Town residents at no charge. '• I• Landscapers in the Town of' Islip have expressed an interest in utilizing this material in their businesses. Middlebush Compost Inc. currently operates a private composting facility in Somerset, New Jersey. The facility accepts from 100,000 cubic yards to 150,000 cubic yards of leaves per year from the New Jersey counties of Essex, Somerset. Middlesex and Union. The facility produces between 15,000 and 25,000 cubic yards of compost product per year which is sold to a local topsoil distributor. The topsoil distributor blends the leaf compost product with soil to increase the organic content of the soil. Different ratios of compost to soil are blended for sale to various uses such as at golf courses, garden centers and landscapers. To date the product demand has exceeded the production rate. • The Town of Southold has been operating a small scale yard waste composting facility since the Fall. The Town has determined that it will take a similar approach to the Town of Islip in marketing the compost product. This approach will stress using the compost products within 40 the Town. These uses include roadside plantings, parks development and maintenance, as a soil amendment in school yards, and as a landfill final cover material. In addition to these in -town uses, Southold will try to develop a cooperative program with a local college to utilize the material not only on campus, but also to evaluate the use of the material for a wide variety of commercial applications. It is anticipated that these plots will lead to the development of contact with commercial nurseries and topsoil blenders who will ultimately pay the Town for the compost and thereby defray some of the processing costs. A commercial operation for the processing of yard waste is currently operating in I'I Yaphank, New York. The facility known as Long Island Compost Corporation utilizes approximately forty (40) one acre sites spread around the East End of Long Island. Each of the sites is a mini -yard waste composting site where after the yard waste has been processed into compost it is transported to the bagging plant in Yaphank. The Yaphank plant currently bags up to four (4) million bags for commercial distribution in the retail market as a soil amendment. 9 is As might be expected, such a wide variety of products demand a variety of prices. Cost is related to the degree of processing required to produce the material, whether the material is fortified with fertilizer, and the quantity of material delivered. As examples, the lease expensive product, wood chips, is available at $13.50 a yard delivered in one yard quantities or for $5.50 per yard delivered in 25 to 35 yard loads. A product referred to as "Light and Leafy Pot Mix" sells for $52.50 per single yard load down to $44.50 per yard in 25 to 35 yard loads. The various other products are available for prices intermediate to those quoted above. 4.2 Method for Removal During the initial phases of the project when the product is used as a soil supplement, the compost product will be removed from the yard waste facility storage area with a front end loader, placed in dump trucks and transported to the Cuthogue Recycling Center at the Landfill Complex. If these dump trucks are required to transport the compost product on the Town roadways then the trucks will be equipped with tarps for covering the material during transport. If, after the initial stakes of the project, the compost product is marketed to the general public or commercial operations, then the options of removal by pickup or bulk deliveries will be examined. 4.3 Poor Quality Compost Based on construction and operation permits previously issued by NYSDEC for yard waste composting facilities it is anticipated that periodic sampling and monitoring of the compost product will be required. The yard waste composting facility in the Town of Islip, New York is required to test on a periodic basis for cadmium, mercury, lead, copper, zinc, nickel, total chrominum and pH. The compost product is to be initially utilized as a soil amendment for local retail, homeowners and Town projects; any material not meeting NYSDEC testing guidelines will be disposed of at an offsite location. After the initial stages of the project, the compost product may be marketed to the general public or commercial operations. If the product does not meet NYSDEC testing guidelines, this material will then also be disposed of at an offsite location. T 0 0 I0 44.4 Change in Market Condition The final marketing/utilization plan would incorporated multiple markets to ensure against over -dependence upon a single user. This strategy provides an economic buffer should a change in specific markets inhibit sales. In the event of such an occurrence, municipal uses will serve as the primary backup. Landfilling the compost by off site disposal will serve only as the ;,worst case" scenario means of disposal. It is anticipated that numerous yard waste composting facilities will become operational in the Tri-state area within the next decade. The increased cost of solid waste disposal and closure of many landfills will necessitate that alternative technologies such as yard waste composting be implemented. `this will increase the competition to sell compost on the open market. The operations in which the most reliable quality of compost and greatest volumes of compost can be produced will have the greatest advantage in marketing its product. The Town yard waste composting operations will be the largest producer by volume on the east end of Long Island. If a reliable quality compost can be produced, the Town will be at an advantage in comparison to its competitors in the sale of the product. 5.0 DESCRIPTION OF FACILITY OPERATION 5.1 Schedule of Operation a). Days and Hours The facility will be open for receipt of incoming yard wastes during the same operational hours as the Town of Southold, Cutchogue Recycling Center. These operational hours are seven days per week from 8:00 a.m. to 4:00 p.m. It is anticipated that the compost processing operations will be conducted during an 8 to 10 hour workday and in the event of peak overloads, the Facility will either operate longer hours each day or operate on weekends until the overload is reduced. The receiving and staging area of the site will be open to incoming vehicles during seasons in which yard waste is generated. It is expected that the yard waste will be received 11 between October 15`x' and December 3151 of each year. Therefore the receiving and staging area will be open for a ten week period. The actual composting process to include turning of the windrows and site maintenance will be conducted year round. b). Preparations before Opening There are no special procedures required prior to opening the yard waste compost facility. The operators will perform a quick survey of the area to make sure that no vandalism has occurred and that all mechanical equipment is operational. The site will be surveyed to identify for correction and repair any potential drainage problems or ponding areas. c). Procedures for Closing Routine maintenance will be performed after the operational day is completed. These services include greasing and oiling equipment, cleaning conveyors, and any other necessary procedures. The site will be prepared for closure by removing any debris from the on-site roadway, applying moisture to the windrows, completing paperwork and properly securing the si te. 5.2 Anticipated Daily Traffic Flow a). Present/Projected Traffic • This section of the report is limited to the potential impacts of yard waste truck traffic on the existing streets and roadways in the immediate vicinity of the composting site. All vehicles travel on designated routes. These vehicle routes are dependent on the location of the waste within the Town. ' Almost all vehicles travel to the Cuthogue Landfill via Middle Road (CR 48). It is assumed that traffic in the landfill area, other than vehicles carrying refuse to the landfill, will increase slightly. This slight increase in vehicle traffic is due to the fact yard waste will be ' received from the Town of Huntington. Changes that will occur in the immediate area of the landfill, which are traffic related, will expedite traffic flow. They include the significant of 12 10 • u L r] u n decrease in overall truck traffic exiting the landfill, by routing the existing trucks and non- commercial vehicles to Depot Lane and Coxs Lane. b). Traffic Routing All vehicles containing yard waste destined for composting will enter the site via the Zacks Lane entrance to the Cutchogue Landfill and be weighed on the existing truck weigh scale. After weighing, the trucks will proceed to the proposed site along an access road at the southwest corner of the landfill to the drop off area at the composting facility. The trucks will then exit via Corporate Road, turning left into Depot Lane and then proceeding back to Middle Road (CR 48). All non-commercial vehicles will also enter on Zacks Lane and proceed directly to a drop off area at the Cutchogue Recycling Center. After the drop off of yard waste the vehicle will exit the site to the east on an interior road to Coxs Lane, turning right to Middle Road (CR 48). The non-commercial yard waste will be transported to the composting site by Town Trucks via the landfill perimeter access road. c). Traffic Conditions The Cutchogue Landfill Environmental Assessment Form contains traffic counts and studies of the existing roads and intersections and develops data on the existing and projected peak hour traffic demand. This data is presented in terms of traffic volumes for the peak hour of travel (determined to be the 7:00 to 8:00 a.m. period) and the computed traffic carrying capacities of the existing and proposed roads in the immediate vicinity of the Cutchogue Landfill. The ratios of traffic volumes to capacities (or V/C ratios) and Levels of Service (LOS) were computed in accordance with the procedures of the latest edition of the Highway Capacity Manual. These values provide a measure of the efficiency and stability of the traffic flow conditions for each of the roadways and intersections surveyed. It would appear from the analysis of this data, as it impacts the Yard Waste Composting Site, that the split -off' of trucks from the overall truck traffic to the composting site presents a minor additional impact on the overall traffic -carrying capabilities of the surrounding road network. Basically, this is due to the fact that the portion of the yard waste which is now transported to the Cutchogue Landfill will now be trucked to adjacent Yard Waste Composting Facility. 13 5.3 Procedure for Unloading Vehicles a) Frequency/Rate Based on the traffic data presented above, it is anticipated that approximately 30 vehicles will enter the Facility daily during the receiving period. Ail vehicles will be unloaded at the bagged leaf storage area immediately after entry. b) Method In the initial year of the operation, leaves will be delivered in plastic bags by the Town of Huntington and will be delivered already cleaned by Town of Southold. Wastes to be accepted will be leaves, brush and grass. It is possible that the method of leaf collection may change in the future to utilize either paper or cornstarch bags which should degrade during the compost process. The only material permitted to be delivered to the site will be that carried by Town of Huntington contracted trucks or residential/commercial vehicles registered in the Town of Southold. These vehicles will only deposit the yard waste in a specially designated bagged leaf storage area, where the loads can be inspected by compost site personnel. The majority of yard waste handling on-site will be accomplished by use of a rubber tired payloader. This will be supplemented by a labor force to periodically check the incoming waste to ensure that only yard waste is being received at the site. Windrow piles will be turned periodically using a windrow turning device, and during the first month of operation the leaves will be turned weekly. Debagging, shredding and screening will also be included in the operations and are described in more detail in Section 6.9 — Process Flow Diagram. 5.4 Special Precautions or Procedures for Operation During Inclement Weather ' Since the composting operations are conducted entirely outdoors, inclement ' weather can affect the operation in many ways. The Facility must be flexible in its design and operation to enable handling of peak loads of leaves during the fall 1 14 0 season and peak loads created by unscheduled maintenance, downtime of mechanical equipment, or Facility closure due to inclement weather. a) Wind A screened earthern berm will be placed at the site along the boundary of the direction of the prevailing wind to reduce the amount of leaves blown Off-site during strong winds. As shown on the site plans, the compost facility is located adjacent to the Cutchogue Landfill, some residential areas and farm fields and any leaves blown off the composting site by high winds will have minimal effect on the surrounding landfill operations. b) Heavy Rain II' Standard operating procedures for composting operations require that the leaves be wet down to provide additional moisture for maximum decomposition by the bacteria. Moisture control will be monitored during • the operations and utility water (water truck or water main) will be added to supplement rainfall events. The composting operation may be affected by heavy rains. The site chosen for the compost operation has adequate drainage so this should not impede the operation. If ponding precludes easy access to the windrows, then cornposting activities would be discontinued until the site is properly graded to allow access. When necessary, gravel and sand will be placed to facilitate access to each individual pile. Heavy rains can also hinder the biological activity in the pile. This would occur if the leaves became saturated and thep ile turned anaerobic. This is most likely to occur when a pile is being formed since the surface area to volume ratio is highest and the rain is most easily absorbed. Since spring is typically the wettest season, this potential hindrance would be most closely monitored during spring. Once a pile is built, saturation is only likely to occur during the spring rains. If the windrows become too wet (>55% moisture), they will be turned to aerate 0 and evaporate the excess moisture. 15 '0 C) Snow/Freezing Conditions Since the composting operations are not expected to receive yard waste during the winter season, the effect of snow/freezing conditions should be negligible. The roadways can become slick and make it difficult to deliver the yard waste material to the site. In these cases, common sense would dictate that collection and delivery to the site would cease during particularly hazardous ice and snow storms. All on-site and access roadways will be built of asphaltic concrete or crushed gravel. Therefore, access to and movement around the site by trucks delivering yard waste should not create any problems during normal snow/freezing conditions. During the winter season, the windrows will still be monitored and turned. Snow on top of the windrow piles will tend to act as an insulating blanket during the cold weather. Due to the insulating features of the snow blanket cover, and based on temperature monitoring, the windrows may require turning more frequently during large snowfalls as compared to small snowfalls. During the winter season, prolonged periods with freezing conditions and no snow may adversely affect the composting process. To maintain minimally acceptable temperatures in the compost pile the windrow turner would operate less than during warmer periods of the year. The less the pile is turned in cold weather and exposed to the freezing air temperatures, the better the windrow pile will be able to maintain higher temperatures. In extreme prolonged cold weather periods, the windrow piles may be combined and made larger to provide insulating properties for maintaining proper temperature controls. Maintenance of more stable temperatures will result in better biological decomposition of the yard waste. 16 J • 6.0 DESCRIPTION OF FACILITY DESIGN 6.1 Equipment Needs Equipment needs are projected utilizing intermediate level composting 'technology. The first few years (2001 and 2002) of the program will process the • volume of leaves collected during a week k p eriod in the Fall. Yard waste during other seasons will be processed beginning in the Spring of 2002. • Wheeled front end loaders will be utilized for moving leaves around the site, forming the initial windrows, feeding yard waste to shredding and screening equipment, keeping space between rows clear, and forming curing plies. 'rile bucket capacity of the loaders will be 4 cubic yards. During the period when yard III • waste is delivered to the site a minimum of two (2) front end loaders will be needed. A minimum of one (1) loader will be needed during the remaining portion of the year for processing requirements. If front end processing is not required and delivered materials can be placed in rows, the number of front end • loaders will be reduced. Pre-processing equipment will include a shredding/grinding operation to break the plastic collection bags open and to shred any oversized material or clumps within the collection bags. A screening process will also be included in the pre- processing operation to remove the majority of the plastic and oversized material. • Self-propelled windrow turning machines will be utilized to turn the piles. Large capacity machines will be utilized during the initial and latter phases of the project. The machines will have the capacity to process a pile at least 6 to 8 feet high and 14 feet wide. During the initial years of the program, at least one (1) • turning machine will be needed and it is recommended that a backup be available to be secured in short notice if the need arises. 17 C: ITo maintain the optimum moisture level in the compost piles a water truck will be utilized. The water truck can also be utilized for dust control. Materials will be • moved around the site with dump trucks with a capacity of 10 to 20 cubic yards. The dump trucks will also be utilized to transport unacceptable or non- compostable material from the site for proper disposal. In lieu of a water truck, a • water main with yard hydrants may be constructed to provide for wetting of the piles. The need for a water main to supplement the water truck usage will be Imore fully evaluated during the design phase of the project . • 1 The end use proposed for the compost will determine the quality required. If necessary, a trommel screen will be utilized to enhance the quality of the compost ' product. The product should be suitable for distribution to residential and A landscaping businesses in the Town of Southold. Monitoring the composting process is recommended. A temperature probe, moisture indicator and oxygen meter will assist in determining when piles should be turned or if moisture should be added. ' The equipment needs for the initial and full scale program are summarized in Table 6-1. 6.2 Surface Nater Control Methods ' The general soil characteristics of the material underlying the site are considered poor subgrade from a structural standpoint, but good subgrade from a drainage ' standpoint. Stabilization of the site area for adequate composting operations will require the backfilling of recycled concrete aggregate (RCA). This material will ' also be used to slope the compost site area to minimize ponding on the site. Drainage swales will be constructed at the perimeter of the site to divert any off- site runoff away from the site. 1 18 n u The site may also require stone till for stabilization and load bearing purposes. • This will increase the ability of the site to drain. The existing topography of the site slopes down to the south. It is expected that on-site drainage will be controlled by a combination of drainage swales and '/z to I percent slopes under the windrows. Surface water runoff will be directed to existing berms at the southern and western boundaries of the property and the existing drainage area will collect and absorb the runoff prior to discharge into the ground from the construction of recharge basin. 6.3 Seed Material Description Leaves have a high organic carbon to nitrogen (C/N) ratio, and this condition can • slow microbial action early in the composting process which will increase composting time. The imbalance corrects itself as carbon is lost in the form of carbon dioxide, while nitrogen is conserved in the system. addition of inorganic nitrogen at the beginning of the process will accelerate decomposition, but it is • not a necessity for leaf composting. If nitrogen supplements are used to reduce composting time, the need for oxygen will be elevated, creating the need for a • greater turning frequency. Enrichment of the end product (compost) with nitrogen, and possibly phosphorus and potassium, would increase the fertilizer value of the compost. The compost is a good soil conditioner without supplements, although it has a low fertilizer value. The benefits and costs of adding the nutrients must be weighed. The compost facility will not be operated initially with any seed material. In • 2002 when the Facility begins to accept grass as part of the yard waste composting operation, then the nitrogen component of the grass will act as a seed material. If in the future the Town determines that a fertilizer market exists for • the compost material then seed materials will be evaluated. IN 6.4 Process Time As previously mentioned, the Town of Southold will only compost leaves for the Fall season of 2001. The leaf compost cycle will be approximately seven to nine months starting in November and ending in July of the following year. This allows two to three months to move the composted material to market. Beginning in the Spring of 2002 the composting facility will receive varied types of yard waste (brass, small brush). Brush and grass will be composted commencing in March and continuing through the Fall. The brush compost season may last at least one year unless a mulch market is developed which can utilize a less stabilized material. Grass will be composted with the other yard waste commencing during the spring and continuing during the Fall of 2002. 6.5 Windrow Construction A front end loader will be used to construct the windrows of leaves. Windrows will be trapezoidal in shape, approximately 14 feet at the base, 4 feet wide at the top and 6 to 8 feet high. Self-propelled windrow turning machines require as little as 3 feet between windrows. During the initial phase of the program a minimum 6 foot spacing will be utilized to allow the operators to become familiar with the equipment. To allow for free movement of the water trucks, every other row will be 10 feet wide to provide space between the rows. The windrows will be turned at least once per week. After one month, adjoining windrows will be combined with the front end loader. The piles will continue to be turned until a finished compost is produced. Water will be added, if necessary, between turnings to maintain optimum conditions. ' The area required during the initial phase of the program does not include the typical reduction in area required by combining piles since collected material will ' be processed only during a six week period during the Fall season. Area requirements are adjusted for combining piles tinder the full scale program, 1 20 Based on the proposed windrow size and the proposed level of technology, one acre of • land is required for every 6,000 cubic yards of yard waste that is collected and windrowed. During the initial phase of the program, approximately 10 acres of land will be required just for the windrow turning area. Staging and storage requirements are estimated at 15 percent of the windrow area, or 2 acres. Total land requirements during 'I• the initial phase of the program, excluding buffer and access roads, is 12 acres. 6.6 Aeration Method/Procedures j • The air required for microbial activity will be supplied by frequent turning, of the windrows and convective action caused by the temperature differential between the piles and the air. The windrows will be placed perpendicular to the prevailing wind direction so that all windrows will be uniformly aerated. During the • summer months, windrow temperature may also determine the frequency of turning. Piles will be turned if internal temperatures approach 130' F, which will prevent microbial die -off from occurring. `burning the pile aerates the material • and prevents the windrows from becoming anaerobic and producing odors. 6.7 Site Access Control Site access will be limited to the Town of Southold employees or their designated • representatives. In addition to the perimeter earthern berm at the compost site, there will also be an additional gate at the compost facility access roadway to ensure that solid waste destined for the Cutchogue Landfill does not get delivered to the yard waste composting facility. Town personnel will also be inspecting the OR contents of the leaf delivery vehicles as they deposit their loads at the receiving area to ensure that unapproved waste is not delivered. • 6.8 Fire Safety Procedures Leaves undergoing normal windrow composting will burn poorly because the interior of the windrow is wet. Vandals may be able to ignite dry surface leaves, but a major fire is unlikely. Based on the site security detailed above, it is not • expected khat ,� andals will easily enter the composting facility site. 21 • t Nevertheless, adequate fire protection will be provided by either water mains and fire hydrants constructed at strategic spots throughout the site or through the use of a water truck which will be used to extinguish fires at the site. In addition, soil -spreading with front end loaders could be used to control or extinguish fires at the site. In addition, the windrows will be kept adequately wet and the facility design allows for quick access, via the aisles, to all parts of each pile in case of a fire. In an emergency, the on-site telephone at the Cutchogue Landfill will be utilized ' to contact the local Fire District. All appropriate emergency personnel have been notified of the proposed facilities construction including the Cutchogue Fire ' Department. Easy access to any local emergency personnel is provided by the Zacks Lane landfill entrance or Corporate Road access off Depot Lane access points. Copies of the notification letter to the affected agencies to respond to emergency conditions follow this section. All appropriate fire protection and fire safety equipment will be provided in accordance with all State and local fire codes. 6.9 Process Flow Diagram The Process Flow Diagram for the facility is detailed in Figure 6-9. The leaves are received from local and Town of Huntington vehicles at the Bagged Leaf Storage Area. The leaves are then transported to the Debagging Area where the plastic bags of leaves are broken open and the majority of the plastic is removed. This ciebagging area may include a combination of shredding, grinding and screening to remove the plastic material. The plastic material will be disposed of off site if no market can be found for the material. The compostable material is then transported either by a front-end loader or dump truck and this homogeneous mixture of leaves will then be placed in the windrow composting area where it will stay for a minimum of six months. 22 • The windrow piles will be formed initially by a front end loader and turned periodically by a windrow turning machine. By turning the windrow piles, oxygen will be added to be utilized by the bacteria to maintain aerobic conditions. Water will also be added during this stage to maintain the optimum moisture IIS content of at least 50 percent (wet weight basis). During the biodegradation of the organic matter (leaves) oxygen is consumed, heat is produced and carbon dioxide and water are given off. After the minimum six month period of turning, the material should be completely composted and the material would then be used as a soil supplement. The Town may elect at a later date to screen the finished compost to market the higher quality compost product on a public or commercial basis. Any residuals recovered in the screening process will be disposed of at an off site permitted location. 7.0 OWNERSHIP/LEASING ARRANGEMENT The Town of Southold owns the property where the compost site is located. The Solid Waste District operates the Cutchogue Landfill and will be operating the composting facility. Initially only Southold & Town of Huntington collected yard waste will be accepted for composting at the facility. The Town will utilize equipment purchased under a capital program to run the Facility. This equipment will include mechanical equipment as detailed in Section 6.1 — Equipment 4eeds and mobile equipment such as front end loaders, water trucks and transport vehicles for both disposing of residue and moving compost for distribution to local users. To the extent that additional equipment is necessary it will be procured to ensure that adequate maintenance capability is available. The equipment will be owned and operated by the Town. All equipment necessary to operations will be maintained by the Town, and backup equipment can be leased on a short-term basis from suppliers if this becomes necessary. 23 • J • 8.0 PERSONNEL REQUIREMENTS/RESPONSIBILITIES Two to five full-time employees are proposed for assignment to the composting facility ' during the six week receiving period of leaves in the Fall. The number of personnel will be reduced during the non -receiving period of the year. An operationserations manager will • coordinate and oversee the daily activities. The manager will be responsible for completing the paperwork required for monitoring and operations at the site. A truck ' scale attendant will preview all incoming material, will direct vehicles to the proper area for depositing their loads, and will be trained to identify unapproved wastes. The site • ' manager will be responsible for disposing in a roll -off container any small size unapproved material received at the compost facility. Records of incoming/outgoing ' material will be maintained by the operations manager. The remaining employees during • the six week Fall period will include construction equipment operators, mechanics, heavy ' equipment operators who will operate the equipment (i.e., front end loaders, windrow turning equipment, screens) used for the composting operation. Prior to operation of the site, all personnel will be trained in proper composting operations including compost biology, pile building, monitoring and troubleshooting. Tile Town may contract with a yard waste composting operations consultant to provide a one month operator training startup and troubleshooting service after this facility has been constructed. The Town will be responsible for the technical aspects of the composting program. Seminars will be conducted by staff biologists to instruct compost facility employees in the proper operation of all phases of composting and to stress the importance of maintaining accurate records of all field data described in the operations and maintenance manual. A detailed operation and maintenance manual will be prepared for NYSDEC review and approval prior to commencing operation of the facility. 24 • 0 9.0 SOUGROUNDWATER CHARACTERISTICS Based on a series of test pits conducted at the site, the property is comprised of • approximately one -foot thick layer of topsoil and surface vegetation. Below the topsoil layer is approximately three to four feet thick layer of loam which as been removed from the site in the areas inside the 50' perimeter buffer zone. Below the loam layer is well - graded sand to depth of 12' below grade in most areas of the site. The test pits were r stopped at twelve feet below the grade surface based on the capability of the backhoe excavating the test pits. The sand layer is well graded sand with excellent drainage capabilities. Based on groundwater monitoring well data from the Cutchogue Landfill groundwater flows in a general northeasterly direction in the general vicinity of the • composting site. 10.0 YARD WASTE COMPOSITION 10.1 Source of Yard Waste The proposed Yard Waste composting facility will only accept wastes generated within the Town of Southold and from the Town of" Huntington. Because the Towns are located in the Northeast and contains deciduous foiliage, leaf waste is • generated in its greatest quantities during the Autumn months of September, October and November. In addition, grass and brush waste are generated throughout the growing season. The major contributors to yard waste production are property owners and, to a lesser degree, landscaping contractors. These contractors typically collect and dispose of yard wastes for private landowners, businesses and industry. The Highway Department is responsible for the disposal of yard waste generated in all Town parks. The amount of yard waste generated differs between Towns as a result of the land area in each Town that contains foilage. The Town of Southold is larger in land surface area than the Town of Huntington. Southold contains less residential • properties and more farmland and therefore will produce less yard waste on an 25 • annual basis than the Town of Huntington. In order to determine the yard waste to be expected at the composting facility, total waste quantities and compositional data for the Town's were analyzed. 10.2 Yard Waste Quantities To determine the design criteria, such as acreage and equipment needs, estimates of the amounts of yard waste to be expected at the Facility are necessary. Methods used to make this estimate include use of previous compositional studies and yard waste generation rate data. To utilize compositional studies, total waste steam quantity data is needed. The Town of Southold and Huntington operates weighing stations at each of their active solid waste disposal and transfer facilities. The data recorded at these stations is accumulated in the Monthly Tonnage Report. Given the location of each of these facilities, the total yard waste generated in each Town can be determined. Based on historic data the amount of yard waste generated in the Town of Southold is expected to be approximately 10,000 tons per year. The amount of yard waste to be received from the Town of Huntington during the initial year of operation (2002) will be approximately 10,000 tons per year. After the initial year of operation the Facility is expected to receive approximately 20,000 tons per year of yard waste from the Town of Huntington. Initially, only yard waste collected material in the Towns of Southold and Huntington will be accepted and processed at the composting facility. Total waste and yard waste brought in to the Cutchogue Landfill and Recovery Center vehicles has not changed significantly over the past three years. Waste composition data in combination with the total waste stream data, will give an estimate of yard waste generation rates. The yard waste components of the waste stream have been determined in studies for several cities as shown in Table 10-2. 26 0 0 r • 27 TABLE 10-2 YARD WASTE COMPOSTING PROJECT Yard Waste as a Percentage by Weight oi'Total Waste Stream Location Spring Summer ball Winter Average heaves Grass Lv&Gr Other (1) Hempstead, NY 14.4 27.1 6.2 0.4 18.0 - - - (2) Cincinnati, OH 27.2 12.6 33 4.1 19.6 - - 16.9 17 (2) Phoenix, - - - - 23.5 8.8 14.7 - - A R.

NY (Aue'88) (4) From Yard Waste Composting: A Study of l=ight Programs prepared by US1:11A (Apr'89) 27 The data accumulated in Table 10-2 shows a range of values for percentage composition of yard waste. In a nationwide survey, Franklin Associates estimates that 20 percent of the total waste stream is considered yard waste; this figure has been affirmed by NYSDEC by inclusion in the New York State Solid Waste ' Management Plan. an. Other estimates of percentage by weight of yard waste include 18 percent by USEPA and 17 percent by Massachusetts DEP. It is estimated that leaves alone ' constitute from one-fifth to one-third of yard waste and between 5 and 20 percent of the total waste stream. As previously mentioned, this range varies widely I based on suburban, urban or rural areas. ' This range includes estimates of 5 to 20 percent of the total waste stream in a New Jersey DEP publication, 5 to 10 percent according to a University of Connecticut ' Cooperative Extension Service publication and 6 percent in Massachusetts DEP publication. Some cities calculated compositional data on a seasonal basis and ' some further divided the yard waste into leaves, grass and others. These figures are somewhat inconsistent between cities, but can be used for estimation ' purposes. All figures in Table 10-2 are subject to different definitions and varying accuracy. Some of the figures presented for the cities include the ' geographical boundary of Long Island. • , As previously mentioned, the Yard Waste Composting Facility will initially accept only leaves collected in the Town of Southold and Huntington for the Year 2001. In addition, only leaves will be collected initially and yard waste, by definition, consists of leaves, grass, small brush and wood chips. Taking the ' above two factors into consideration and in light of the fact that there is no compositional data detailing the percentage of leaves for urbanized areas in the ' total waste stream, a more accurate estimate of the leaf to total waste generated in ' The Town of Southold is between 5 to 8 percent. Based on the above 28 K. I0 assumptions it is estimated that approximately 80,000 cubic yards of leaves will be received at the Yard Waste Composting Facility for the ten week collection period for 2001. 10.3 Composition of Yard Waste Little general data is available on the components of yard waste by percentage because much of its arrives in a mixed form at solid waste facilities. Some data is detailed in Table 10-2; the basic components are leaves and -,crass. `-Others" I• typically include brush, shrub trimmings and garden waste and wood chips. Results of a Cornell Cooperative Extension survey of Brooklyn landscaping contractors give an indication of the composition of yard waste generated in New York City: 66 percent are grass clippings, 20 percent are leaves, 10 percent is brush and 4 percent is wood. These values are based on estimates by each contractor of the percentages of each component of yard waste and may range in accuracy from actual recorded weights to inaccurate estimates. Therefore, use of these figures in further calculations may lead to erroneous results. Chemically, yard waste is composed of nitrogen, phosphorus and potassium, the same ingredients found in fertilizer. Low levels of lead are sometimes found in compost but are rarely a constraint on marketing and use. This is a result of lead in auto emissions which is absorbed by leaves. The lead concentration figures have decreased with stricter emissions regulations. 0 11.0 MONITORING Signs will be posted at the entrance to the facility to indicate the purpose of the facility and the materials that will be accepted (i.e., leaves, grass, small brush) and materials that will not be accepted (i.e., construction and demolition, municipal solid waste, paper, metal products, and toxic and hazardous wastes). WE 0 IAll deliveries of compostable material will be inspected at the Bagged Leaf Storage Area ' prior to incorporation into the windrows. While it is unlikely that hazardous waste will be deliberately delivered to the site, personnel will be properly instructed to immediately identify Such waste and to arrange for immediate and proper disposal by a NYSDEC licensed contractor. NYSDEC will be notified of such an occurrence and pertinent 0 1 information will be maintained on the daily log sheets. ' 11.1 Compost Process Monitoring If the Town of Southold decides to market the compost on a public or commercial ' basis, the compost will be periodically tested. The purpose of compost sampling and an, will be to determine the chemical mixture of the final product prior ' to distribution. Composite compost samples will be analyzed as required by the Permit to Operate conditions and as required by NYSDEC. Samples will be collected from a minimum of six (6) windrows and analyzed according to NYSDEC protocols by a NYSDOH certified laboratory. For the composting process to be most efficient, the critical items to be monitored include moisture content, temperature, pH and oxygen level. These monitoring activities will be the responsibility of the operations manager who will record the ' data on the forms detailed in Section 13 (Operating Records) of this document. This data will then be examined to determine the frequency of turning of the windrow piles. Troubleshooting and process monitoring control will be provided 7 in the Operations and Maintenance Manual for the compostint, facility. 11.2 Site Monitoring ' Adjacent to the composting site is the Cuthogue Landfill. Groundwater monitoring wells are on the landfill site. These wells are to be installed under the landfilI capping program. These monitoring wells will be utilized for monitoring the potential impact of the composting operation on the groundwater quality. 1 30 Compost leachate is not expected to be a problem at the facility site for two reasons. namely, the existing land use is agricultural and analytical data has demonstrated that yard waste compost leachate toxicity is not a significant environmental problem. With respect to the latter, E.P. 'Toxicity analysis performed by the Town of Islip, New York on a composite sample of leaf compost supports this conclusion. The Town of Southold will also collect periodic composite samples for analysis as required by NYSDEC. It is assumed that test results from the existing groundwater monitoring wells at the landfill will indicate the presence of leachate from past solid waste disposal a practices and chemical agents used in farming operations. Therefore, it may be difficult to determine the impact of the composting facility leachate on the groundwater quality. Samples of any surface water ponding on the composting . site may be more representative of the potential impact of compost leachate on the groundwater. Leachate indicators including specific conductance, total dissolved solids, total organic carbon, chloride, ammonia, alkalinity and pH will be sampled on a periodic basis. If, as a result of operation of the compost site, significant groundwater contamination is detected, the Town will undertake contingency steps to remediate the site. This may include the installation of groundwater monitoring i wells at the perimeter of the yard waste composting site. The impact of composting on surficial soils will be evaluated by the chemical analysis of composite compost samples collected from beneath a minimum of six (6) windrows prior to distribution of the final compost product. Soil samples will be analyzed for the same chemical constituents as the composite compost analysis and as required by NYSDEC under the Permit to Operate. 31 0 Samples will be collected from a minimum of six (6) windrows and analyzed according to NYSDEC protocols by a NYSDOH certified laboratory. 12.0 CONTINGENCY PLAN 12.1 Equipment Breakdown Equipment used during on-site operations of the Facility will be owned and regularly maintained by Town personnel. In this instances where specialized equipment, i.e., screens, grinders, etc., may be utilized on a lease basis, a maintenance agreement will be provided by the vendor to ensure continuos operation. if an unforeseen equipment breakdown does occur, the equipment will be replaced immediately in-kind while the repairs are performed. Rolling stock such as collection and transport vehicles are maintained on a regular basis by the Town or outside contractor. Spare parts will be provided for the mechanical pieces of equipment, which are deemed critical to the operation. 12.2 Odor Control Odor control at the Facility site will be accomplished through a combination of best management practices, site drainage and pro -active odor monitoring. Best management practices include proper construction and maintenance of windows to ensure maximum aeration and elimination of odor -causing conditions. Site drainage will direct runoff from the window to the south and west away from nearest neighbors that may be affected by odors from standing water. In addition, on-site drainage into the soil will eliminate standing water and any runoff from the construction of drainage swales. The location of the site is also advantageous with respect to minimizing odor impacts due to the fact that the nearest residences are located south of the site and the prevailing winds at the site are from a west to east direction. These receptors in the south are located approximately 500 feet from the compost site. 32 I• 12.3 Vector Control Insect and mammalian vectors, such as rodents, are attracted to a given location if water, food and shelter are readily available. The operation of a compost facility is not conducive to vector habitation, if properly managed. For example, ponding III• due to excessive application of water, may be a potential source of insect vectors, such as mosquitoes. Properly trained personnel will be aware of this potential concern and will be instructed to inform the site manager and will assist in • preventing such an occurrence. Rodents are especially troublesome if decomposable food is readily available. Problems in this regard will be prevented in two ways. Initially, _yard • waste will be monitored by site personnel to eliminate the inclusion of food waste with the yard waste. Routine site inspection will be conducted by personnel to monitor for the presence of rodents. A program of rodent baiting wil I be conducted if rodents are detected, in accordance with the requirements and recommendations of the County Health Department. 12.4 Spill Control Spill releases may occur at an active site where light or heavy equipment is routinely used during the workday. In this regard, liquid fuel spills will be eliminated by frequent inspections ensuring that no leaks are occurring. fuel storage on-site will be de-emphasized by the transportation of heavy equipment to • and from the Facility before and shortly after daily closing. Equipment retained on-site will be done so in a secure, fenced -in area or a storage building at the landfill facility to minimize vandalism. 33 If an unforeseen spill does occur, immediate steps will be taken to reduce environmental impacts to groundwater. Absorbent pads will be used to contain ' and collect any spilled fuel or lubricant materials. In addition, contaminated soils will be excavated and transported to an approved disposal site. Daily log sheets will also be maintained for inspection. Finally, appropriate Ton and NYSDEC • ' personnel will be notified if a spill does occur. ' 12.5 Delivery of Unapproved Wastes The Facility will only accept leaves for the Fall Season of 2001. In the Spring of ' 2002, the Facility will begin accepting small brush and grass. All the waste including garbage and hazardous waste will be banned from the Facility and as indicated by the placement of a suitable sign at the Facility entrance. All truck deliveries of compostable material will also be inspected in the storage area and ' prior to incorporation into the windows. Inadvertent deliveries of unacceptable waste will be handled by removal of such material from the site and transportation ' to the Town of Southhold collection and recycling facility. 1 12.6 Emergency Response Arrangements I� Emergency actions on-site include not only responses to tires but medical assistance to personnel. Fires are uncommon at a properly managed yard waste compost site. Because ' water is periodically applied to windrows, the potential of fires is minimal. However, if a fire should occur, immediate steps will be taken to extinguish the ' fire. "These measures include the immediate application of water through the use of a water truck and on-site water supply, as well as the application of quantities of sand to immediately smother a fire. Since the payloaders would be used to transport sand needed to smother a fire, personnel will be properly trained in the appropriate techniques of fighting such a fire. If additional help is needed, telephone contact will be made with the local fire department. 1 34 I0 Similarly, personnel will be properly instructed in the use of all equipment in an • effort to prevent work-related injuries. A first aid kit will be available on-site for • minor injuries; however, telephone and radio contact will be maintained with the emergency medical technicians available in the local response team. In both instances, fire or medical emergencies will be recorded on daily lop, sheets. • 12.7 Emergency Equipment As indicated in Section 12.6 (Emergency Response Arrangements), emergency response equipment will be either on-site or immediately available to service the • Facility in the event of a fire or medical emergency. Since the yard waste compost operation is a medium technology management technique, extraordinary measures are not considered necessary to respond to potential emergency occurrences. Other than fires, the potential for illegal delivery of hazardous waste I�• may be possible. Under such circumstances, the area would be immediately isolated from use and the hazardous emergency response team from the Suffolk County Department of Health Services would be notified along with Town 0 officials, the local fire department and the NYSDEC. Removal of hazardous waste would be immediate and such waste would be transported to an NYSDEC permitted landfill by a properly licensed NYSDEC contractor. • Copies of letters forwarded to the local emergency responders are included at the C end of the report to familiarize the agencies with the location and operations of the composting facility. 12.8 Evacuation Procedures Evacuation of the Facility would be accomplished in cooperation with Town officials, the local fire department and the local police department. 35 -<- Initially, personnel would be instructed to immediately notify their superiors and take immediate steps to prevent further access to the Facility. All personnel would leave the premises in an evacuation situation. The entrance/exit gates would be closed and locked pending final determination of the acceptability of re- entry into the Facility through joint determination by Town and State officials. If additional steps are needed to evacuate the immediate businesses or residences near the Facility, Town public safety and police officials will do so through door- to-door notification. 13.0 OPERATING RECORDS The operations manager or his designee will keep the following records: I . Log of daily deliveries of yard waste to the site; including volumes, and types of material entering the site. 2. Log of daily removal of compost, other products, and residuals. 3. Logs of temperatures, moisture, pH and oxygen achieved in the piles. 4. Logs of routine monitoring results on compost qualify. 5. Logs of operational problems on the site. 6. Records of water consumption Sample copies of the data/log sheets are provided in Appendix 9. 36 6 14.0 FACILITY MAINTENANCE MEASURES 14.1 Roadway Maintenance Facility entrance and exit roadways will be maintained by Town personnel to ensure continued operation of the Facility. Appropriate coarse base materials will be applied to maintain on-site roads as needed, and paved roadway surfaces will be provided as the access roadway from Middle Road (C.R. 48). 14.2 Equipment Maintenance All equipment will be maintained in operational condition through a preventive maintenance program managed by the 'town. On-site repairs will be accomplished by 0 Town personnel. A maintenance record will be kept for each piece of equipment used at the Facility site. It will be the responsibility of the operations manager to ensure that all equipment is maintained and in proper working condition. 14.3 Utility Maintenance Maintenance of Utility service to the Facility will be the responsibility of the respective utilities including Long island Power Authority and the local Telephone 0 Service Provider. Site personnel will be instructed to immediately notify the respective utility if failure does occur and to maintain a written record of each occurrence. 14.4 Closure As previously discussed, the composting facility is located on a separate and adjacent site from the Southold landfill. The composting facility is to be considered a permanent facility as the Town has in its long range plans, determined that the site will be utilized for long term processing of yard waste into a marketable compost material. Therefore, closure of the composting facility site will be predicated on the requirements of NYSDEC at the time in the future if the town determines to no longer operate the yard waste composting facility. f 37 Cl 15.0 PERMIT TO CONSTRUCT APPLICATION/SSE R DETERMINATION The application for Approval to Construct a Solid Waste Management Facility (NYSDEC from 47-19-2 (4/85)) is included as Appendix 10.

The landfill is situated in a rural, agricultural area of Cutchogue, approximately 2.5 miles east of Mattituck and 8 miles west of the Incorporated Village of Greenport. i The landfill property is approximately 62 acres, including the 17 acres north of the landfill which was formerly used for borrow operations and I acres south of the landfill currently used as a waste collection and recycling center and transfer facility. The area formally Y used for landfilling, including two former scavenger waste lagoons located in the western portion of the landfill, comprises 34 acres. The Town of Southold initiated operations at the landfill site in 1920 for the disposal of municipal solid waste, refuse, debris and scavenger (septic system) waste, and operated the landfill continuously until 1993, when it was closed. 1.2 Landfill Closure Design The current contour elevations and drainage characteristics of the closed Southold Landfill (see Figure 1-2) reflect the intent of the New York State Department of Environmental Conservation (NYSDEC) - approved Final Closure Plan design and the results of construction ♦ 1314\0313301 Aoc(R05) 1 _ 1 I9 0 lu 0 0 10 0 10 p t4% Fort NEW YORK 0- 6 QUADRANGLE LOCATI ay�y s6 1SOUTHOLD 5 NN -LANDFILL IN/ 0 IN A 0 -4 V 7 A. k 0 I L"4 C, earl 0i Cem, o 4. 4 ........... ,CuclAlo IUec X z U C 40 �4\ BA 32 V -V* \ +0 ` i� tchoove A I North For li % pflCountry Club 4 ., � - ..:><.: ,�:• , A'.Z •� �� of �� � y , � , 0 0 2000 Source: USGS MATTITUCK HILLS, N.Y. & SOUTHOLD, N.Y.

For the purposes of the following discussion, and consistent with design of the subgrade grading plan, the landfill is divided into eastern and • western sections, which are delineated by the main access road which runs in a north/south direction through the center of the landfill cap area. The final cover for the Southold Landfill was designed to: (1) support vegetation; • (2) protect the hydraulic barrier layer (i.e., the geomembrane) from physical damage; (3) restrict precipitation from infiltrating the landfill waste mass; and (4) provide collection and passive venting of the landfill gases. The installed capping system consists of the following, from the surface downward: • Topsoil Layer: A 6 -inch surface layer of uncompacted soil capable of supporting vegetation; • Barrier Protection Layer: A 12 -inch layer of clean fill; • Geocomposite Drainage Layer: A fabricated composite consisting of a geosynthetic (polyethylene) drainage layer (geonet) core with a nonwoven geotextile (8 oz./sq. yd., polyethylene) permanently bonded to each side of the geosynthetic drainage Iayer, • which was installed in all drainage swales and over areas with slopes of 20 percent or greater; • Geomembrane Cap: A high-density textured 60 -mil flexible polyethylene (HDPE) geosynthetic liner; • • Gas Venting Layer: A 12 -inch layer of sand with a minimum coefficient of permeability of 1 x 10-3 cm/sec. Passive gas vents are placed within the sand to collect gas from this layer and vent the gases to the atmosphere; and II• • Prepared Subgrade: The prepared subgrade surface serves as the graded and compacted surface upon which the veneered layers of the capping system are sequentially constructed. The prepared subgrade surface was achieved through a combination of activities which included: excavation of waste in areas of cut, relandfilling of excavated waste in areas of fill, and placement of contour grading material (general fill) to achieve the proposed subgrade contours. The subgrade was completed within a 6 -inch layer of soil. Because the final subgrade layer and gas venting layer comprised the same material, no geotextile was used between these two layers. The above-described capping system was constructed over the entire landfill waste mass. 'w 01314\r0313301.doc(R05) 1-4 G 11 1.3 Purpose and Scope The purpose of the Southold Landfill Post -Closure Monitoring and Maintenance Manual is to define the procedures for personnel performing routine inspection, maintenance or repair work on the landfill following its closure. The Manual is based upon the site remaining in an as - built and fully passive state. Any change in use requires Town and NYSDEC approval and revision, update and/or modification of this Manual. This Manual has been prepared in accordance with 6 NYCRR Part 360 requirements effective November 24, 1999. The Manual is intended to ensure the following: • Site is maintained effectively and efficiently; • Site is monitored for the prescribed parameters; • All parties are aware of the specific monitoring and maintenance needs of the site; and • Provide a smooth transition of the site from the closure construction phase to the post -closure monitoring and maintenance phase. The guidelines and procedures presented in this Manual are based on site-specific information, including: • Site visits • Southold Landfill General Construction Contract (Contract No. 2000) • Southold Landfill Final Closure Plan • As -built construction conditions The Post -Closure Monitoring and Maintenance Manual includes the following information: • Site Inspection Guidelines ♦ 1314VO313301.doc(ROS) 1-5 I0 • Maintenance and Repair Procedures • Groundwater Monitoring Plan • Landfill Gas Monitoring Plan • Personnel and Equipment Requirements • Contingency Plan • Post -closure Cost Estimate • Communication Procedures • Record Keeping and Reporting I• I• • ♦ 13141r0313301.doc(RO5) 1-6 I0 Section 2 L 2.0 SITE INSPECTION GUIDELINES Following the closure of the Southold Landfill, the site will be monitored in accordance with 6 NYCRR Part 360-2.15 criteria. The monitoring process requires the inspection of the site at least four times a year by qualified, trained landfill personnel. In addition, inspections will also be performed after a specified rainfall event (5 -year storm or greater as required by NYCRR Part 360). The results of these inspections will be recorded on the Post -Closure Site Inspection Checklist, a copy of which is provided in Appendix A. The location and extent of any damage discovered during an inspection will be noted on the inspection checklist form, along with any • necessary additional information. Any irregularities found during these site inspections will be remediated according to the guidelines provided in Section 3 of this Manual. A copy of all the inspection reports will be maintained on file in the offices of the Town of Southold Solid Waste Coordinator located at the landfill site and included in the facility's annual report. • 2.1 Cap Integrity During closure construction, a minimum of 18 inches of soil cover was placed over the geomembrane. The cap must be inspected to assure its continued integrity. 2.1.1 Soil Cover The soil cover will be visually inspected for signs of erosion damage, settlement, cracking, vectors, leachate or waste breakthrough, vandalism, litter and unauthorized dumping. Erosion, settlement or cracking of the cover soil will be considered damaging, based upon whether the function of the final cover had been impaired in the affected area, e.g., ponded storm water. The minimum final cover thickness must be maintained at 18 inches. The Town will perform visual observation to determine if settlement has occurred. The following will be noted on inspection logs: • Visible debris or litter (housekeeping); `1314W313302.D0QR06) 2-1 10 0 • Visible waste (indication of damage to the cap); • Signs of unauthorized dumping or vandalism, such as vehicular tracks or disturbed • cover soil; and • Evidence of surface leachate (indication of damage to the cap). 0 2.1.2 Vegetation The soil cover was vegetated during the cap construction according to the seeding specifications approved through the submittal process. Inspections of the vegetation will be performed to monitor the vegetative growth and identify problem areas which require reseeding. The vegetative cover will be inspected for bare spots, dead species and undesirable species. Bare or dead areas of vegetation will be further examined for the possibility of landfill gas, erosion or vector damage. The apparent cause of any damage will be noted in the inspection report. 2.2 Storm Water Collection and Recharge System The storm water collection system for the Southold Landfill closure construction consists of open drainage swales, subsurface piping and drainage strictures (such as a stilling basin, catch basins, headwalls and manholes), which convey collected storm water runoff to the three on-site groundwater recharge basins (see Figure 1-2). • Each of these structures will be monitored for wear or damage and the results of these inspections will be reported in the inspection logs. Any necessary repairs will be performed in according to the guidelines provided in Section 3 of this Manual. r All of the storm water collection, conveyance, drainage and control structures will be visually inspected for obstructions, siltation, ponded water and erosion damage, such as washouts. The location of any obstruction or damage and its cause, if known, will be noted in the inspection logs. Drainage swales will also be inspected for loss of vegetation, collection of debris or damage to the erosion control fabric. • ♦ 1314\R0313302_DOC(R06) 2-2 Ll The drainage swales for Recharge Basin 2 consist of a section of rend mattresses and stone fill_ The drainage swales for Recharge Basin 3 consist of a section of reno mattresses and stone fill • foIlowed by riprap aprons. The stilling basin, manholes and catch basin for Recharge Basins 1 and 3 are constructed of precast concrete. The headwalls and apron for Recharge Basins 1 and 3 are constructed of cast -in-place concrete followed b ri ra and stone fill P p y p p These structures will be examined for damage or instability which could affect their performance. Erosion of soil beneath or around the structures or reno mattresses, or signs of slippage of the structures, will be noted on the inspection logs. • 2.2.1 Diversion Swales and Gravity Storm Water Drains Open drainage swales were constructed to convey storm water runoff from the landfill without damaging the integrity of the cap. The northern swales receive storm water runoff via diversion swales from the northern portion of the eastern and western halves of the landfill. Storm water from the northeastern and eastern portions of the landfill is discharged to Recharge Basin 3 and storm water from the northwestern portion of the landfill is discharged to Recharge • Basin 2. The southern swales receiving storm water runoff discharge to a drain system which discharges to Recharge Basin 1. Recharge Basins 1 and 3 also receive storm water from gravity storm water drains along the southwestern and eastern edges of the landfill. respectively. The drainage swales, stilling basin, catch basins and manholes will be examined on a regular basis for • signs of debris erosion and/or sediment buildup, and noted in the inspection logs. On occasion, storm water control structures may become damaged and diminished in function by intense rainfall events or by alternating freeze -thaw cycles. Stone fill is particularly • susceptible to movement by erosion and undermining. Care should be taken to inspect reno mattresses, as well as the diversion swales, after intense rainfall events. If erosion or undermining is observed, the Town should notify NYSDEC immediately and corrective action should be taken. • Any obstructions found in and along the storm water collection route will be promptly removed. Eroded vegetated areas will be promptly filled with imported soil fill, compacted and seeded. Eroded or undermined armored channels, such as areas with reno mattress, well have the • ♦ 1314\R0313302.DOC(R06) 2-3 subgrade material repaired with material equivalent to the original construction and the mattress area repaired or replaced, also with material equivalent to that used in the original construction. Any sediment buildup will also be promptly removed with hand tools and will be spread over existing grassed sideslopes. 2.2.2 Recharge Basins The groundwater recharge basins, located on the northeast, northwest and southwest corners of the landfill, receive storm water discharge from the landfill. Periodic removal of silt and other fines may be necessary to maintain the proper functioning of the three recharge basins. The recharge basins' sideslopes will be periodically inspected and monitored for signs of erosion and repairs will be made, if required. U, j 2.3 Access and Maintenance Roads The access and maintenance roads for the Southold Landfill consist of a main access road, an east maintenance road, a west maintenance road and a middle maintenance road. Portions of the west maintenance road and the main access road are paved, while the remaining roads are constructed of a recycled concrete aggregate having a minimum thickness of 6 inches (Figure 1-2). Visual inspections of the roads will be conducted for potholes, erosion gullies, loss of aggregate cover and obstructions. The results of these inspections will be noted on the I inspection logs and repairs made, if required. 2.4 Landfill Gas Monitoring A passive venting system was installed on the landfill to allow venting of landfill gases through the geomembrane. During the post -closure monitoring period, these vents will be inspected for damage, such as excessive settlement which causes stress on the geomembrane or signs of vandalism. The vents will also be inspected for signs of vector infestation. The inspection report will reflect any damage noticed during the inspection. The functioning of these 4 13 MR0313302.DOC(R06) 2-4 I0 I• u 1%] 0 El vents will be monitored during air quality testing which will be performed at the site according to the guidelines provided in Section 5 of this Manual. Perimeter landfill gas migration control trenches are located in areas along portions of the northern, southern, western and eastern property boundaries. These trenches were constructed to control off-site migration of landfill gas. These trenches were constructed to a depth of 10 feet, lined with geotextile and filled with gravel. These trenches will likely not require any maintenance during the post -closure period. Fifteen perimeter gas monitoring wells are located at approximately 200 -foot intervals along the southern, western and eastern property boundaries. These wells are located at the property boundaries beyond the gas migration control trenches. Explosive gas monitoring at these wells will be performed regularly during the post -closure period. Explosive gas monitoring will also be performed in the scale house and at the six gas vents in the collection center. The intent of the regular monitoring at these Iocations is to identify the presence and concentration of explosive gases and determine the extent of landfill gas migration, and to determine if corrective action is necessary to mitigate gas migration, Gas monitoring wells will be visually examined during each routine inspection and the functioning of each well will be checked during each monitoring event. The details of the gas monitoring program are presented in Section 5 of this Manual. if a monitoring well sustains damage or cannot provide a representative gas reading, the well will be examined to determine whether the problem can be corrected. This determination will be facilitated by comparing data from previous monitoring activities. The inspection report will include the details of any gas monitoring well damage and the appropriate action that will be taken to correct the problem, as presented in Section 3 of this Manual. ♦ 13141R0313302.DOC(R06) 2-5 2.5 Groundwater Monitoring Wells 'Twelve groundwater monitoring wells are installed at six locations at the landfill. Each location comprises two wells, one shallow (water table) and one deep (approximately 100 feet below the water table). Two wells are located upgradient of the landfill to determine background/ambient groundwater quality, and the remaining wells are downgradient to monitor landfills impacts on groundwater quality. Groundwater monitoring wells will be visually examined during each routine inspection and the functioning of each well will be checked during each quarterly sampling event. The details of the groundwater sampling program. are presented in Section 4 of this Manual. If a monitoring well sustains damage, or cannot provide representative groundwater samples, the well will be evaluated to determine whether the problem can be corrected. This determination will be facilitated by comparing data from previous monitoring activities to determine the cause of the problem. In particular, the following signs of damages or deterioration will be examined: • Encrustation and corrosion; • An exceptional increase in solids content (e.g., from the breakdown of the screen); • An appreciable decrease in groundwater elevation, perhaps the result of these problems. The inspection report will include details of any well damage and the appropriate action that will be taken to correct the problem, as presented in Section 3 of this Manual. Damaged wells that cannot be rehabilitated will be decommissioned by appropriate methods (i.e., overdrilling, pulling of casing or grouting in place) and replaced by construction of a replacement groundwater monitoring well to re-establish the integrity of the sampling plan for groundwater monitoring. ♦ 1314\R03 m 3302.DOC(R06) 2_6 '0 2.6 Site Perimeter Fencing Site perimeter fencing consists of 6 or 12 -foot high chain link fence and temporary fencing on the eastern boundary of the landfill. The gates for the site are located on the east side of the landfill on Cox Lane and on the south side of the landfill on Middle Road. The fencing will be visually inspected for any signs of vandalism or trespass including, but not limited to, damaged or cut fence fabric, bent fence posts, rails or gates, damaged locks or chains, etc., and repairs will be made, if required. ♦ 13141R0313302.DOC(R06) i i 2-% Section 3 0 • 3.0 MAINTENANCE AND REPAIR PROCEDURES • The need for maintenance or repair work will be governed by the observations made during the regular site inspections previously described in Section 2, and records of this work will be maintained in the permanent landfill files at the Town, This section describes the maintenance and repair procedures which will be followed during the post -closure inspection and • monitoring period for the Southold Landfill. The personnel and equipment requirements for this 30 -year period are presented in Section 6 of this Manual. 3.1 Maintenance Routine maintenance work will be performed, as necessary, during the 30 -year post - closure monitoring period. Mowing, regrading of the cover soils, access and maintenance road • repair, additional seeding, vector control and the removal of undesirable vegetation species are considered typical maintenance tasks and are discussed in this section. 3. 1.1 Landfill Gas Control In addition to the landfill gas monitoring program that will occur at the perimeter monitoring wells, maintenance of the gas vents will also occur. During the post -closure period, I • the vents will be inspected and maintained on a regular basis. 3.1.2 Drainage and Erosion Control Surface drainage features to control and convey storm water runoff have been designed for the 100 -year, 24-hour storm. The groundwater recharge basin system has also been designed for the 100 -year, 24-hour storm. The drainage swales will be maintained with grassed channels. Complete vegetative coverage will be maintained and will be inspected at the same time the landfill cap is inspected. Areas of erosion will be noted and repaired as soon as possible to maintain the integrity of the cap. Discharge areas will be inspected for foreign debris and sediment which may interfere with its proper functioning, and for areas of erosion which may ♦ 13141R0313303.DOC(R03) 3-1 0 sediment which may interfere with its proper functioning, and for areas of erosion which may degrade the integrity of the cap. The recharge basins will be kept free of litter and foreign objects 0 that would inhibit groundwater recharge and degrade the integrity of the sideslopes and basin floors. Vegetation species that would inhibit access for maintenance purposes will be removed. In addition, the accumulation of silt on the basin floors which interfere with recharge will be 0 removed by periodic scraping of the basin bottom. The gravity storm water drain piping, catch basins, stilling basin and manholes will be periodically inspected for debris, sedimentation and visual settlement of the catch basin, stilling 0 basin and manhole structures. Debris and sediment in the piping, catch basins, stilling basin or manhole structures will be periodically cleaned. The cleaning will consist of rodding or flushing of the pipeline with appropriate sewer cleaning devices and hand or equipment excavation of the • interiors of manholes and catch basins. If entry into any of the catch basins, stilling basin or manholes is required, continuous gas monitoring and ventilation of these structures with an explosion proof blower will be implemented, along with confined space entry procedures. 0 3.1.3 Vegetative Cover The vegetative (grass) cover will be mowed at the discretion of the Town to control the growth of wild and deep-rooted species, and to minimize the potential for the introduction of vector habitats. The frequency of each mowing event will be determined by the site conditions. Undesirable species, such as saplings or other vegetation with penetrating roots discovered during inspections, will be removed if their presence poses a threat to the integrity of the final • cover system. Herbicides and insecticides will not be used to control undesirable plant and/or animal species unless the nonchemical methods do not yield desired results. NYSDEC will be notified of the use of herbicides and insecticides prior to use. Areas of the cap with dead vegetation or lack of vegetation will be inspected by qualified personnel for possible causes of defoliation and devegetation. Bare areas of the cap will be seeded according to the seeding specification provided in the Landfill Closure Construction Contract Documents (Contract No. 2000). ♦ 13I41R0313303.DOC(R03) 3-2 3.1.4 Regrading The effects of landfill subsidence, vandalism or gulleying from minor precipitation events (i.e., not causing extensive damage to the site) may result in the need to reestablish the affected areas of the cap system. The areas of erosion or landfill subsidence which affect the performance of the cap system will be restored to original grade to prevent surface ponding and further collection of water on the cap membrane. Deterioration of the access and maintenance roads will be repaired by regrading where possible, by the placement of additional RCA or repaving, if necessary, to provide access for routine inspections and maintenance activities. If vandalism is r detected on the site, such as off-road vehicle tracks, the Town will pursue additional efforts to further restrict access to the site. ♦ 1314\R0313303.DOG(R03) 3-3 �I I 3.1.5 Vector Control and Aesthetics • Vectors common to active landfill operations are not expected to be a problem at the closed landfill. However, suspected rodent or insect infestation will be addressed b contacting P Y g qualified licensed exterminators. Prior to initiating an extermination program, the Town will advise the NYSDEC of the situation and, if necessary, develop and submit to NYSDEC an extennination work plan for review and approval. Details of the communication procedures for nonroutine events are provided in Section 9 of this Manual. 3.1.6 Access Access to, and onto the landfill will be continually maintained. Vehicular access will be limited to authorized personnel and will only be accomplished through the main site entrance off County Road 48 and exit onto County Road 48, Cox Lane or the Town's Compost Facility along the boundary landfill. The be inspected for western of the access and maintenance roadways will • foreign objects and vegetative growth which could degrade their integrity and inhibit access. ♦ 1314\R0313303.DOG(R03) 3-3 �I I I 17 3.1.7 Fencing A six-foot high chain link security fence surrounds the majority of the perimeter of the site with 12 -foot high chain link fence in the vicinity of the collection center/transfer station. Two 20 -foot wide double leaf gates are located at the entrance from Middle Road and Cox's Lane. Periodic inspections will be made of the fences to determine if they have been damaged by vandals or the weather. Routine repairs will be made to damaged sections using the same type and quality materials as were used in the original fence installation. • 3.2 Repairs This section details the procedures which could be used to perform nonroutine repairs of the cap system and, as such, are considered to be outside of the scope of the normal maintenance procedures for the landfill. These activities may include, but not be limited to, repair of storm water structures, the geomembrane, gas vents, landfill gas monitoring wells, groundwater monitoring wells and the vegetative cover. 3.2.1 Storm Water Structures Should settlement of the gravity storm water drain piping, manholes, catch basins or stilling basin be observed during routine maintenance and cleaning of the pipeline and structures, the Town will monitor the area where the settlement has occurred in order to determine the nature of the settlement and whether the geomembrane cap may have been damaged or disrupted. 3.2.2 Geomembrane If the geomembrane cap has been damaged or disrupted, the Town will immediately notify the NYSDEC of the problem and propose a plan to repair the liner. This proposed plan will incorporate the requirements for repair of the cap membrane. Upon approval by the NYSDEC of the proposed repairs, the Town will proceed and implement the repairs as set forth in the proposal. ♦ 1314\R0313303.DOC(R03) 3-4 n u I• I• Once the geomembrane cap :has been repaired, or if excavation reveals that the geomembrane cap has not been damaged, the Town will backfill the area of settlement with compacted backfill material. Proper construction procedures will be followed as set forth in the closure design drawings and specifications for the Southold Landfill. 3.2.3 Gas Venting System Landfill gas vent damage will most likely occur during normal maintenance of the site, such as during mowing. If damage occurs to a gas vent, the vent will be replaced according to the approved closure construction documents. Breakage of landfill vents, which can damage the membrane beneath the cover soils or the watertight seal around the pipe penetration, will be examined. The cover soils will be removed and the membrane and pipe penetration boot inspected for damage. If damage has not occurred, the soil layers around the vent will be replaced by hand and compacted to a minimum thickness of 18 inches. All repairs will be such that replacement layers will match and tie directly into the undisturbed portion of the cap. Damage to the membrane or the pipe penetration boot will be repaired according to the guidelines provided in Section 3 of this Manual. 3.2.4 Landfill Gas Monitoring Wells The repairs required for the landfill gas monitoring wells may involve installation of a new monitoring well. Repair of the well will be based on the extent of the damage observed and the corrective action will be discussed with and approved by the NYSDEC prior to their implementation. Abandonment of the well will be performed in accordance with the closure construction documents and will include, but not be limited to, the following procedures: • Removal of surface protective casing and concrete slabs, as appropriate; ♦ 131 AR0313303.DOC(R03) 3-5 The repairs required for groundwater monitoring wells may involve: 1. Redevelopment of the well; 2. Removal and replacement of the well screen; or 3. The installation of a new monitoring well. The repair technique used will be determined by the extent of the damage observed. However, any corrective measures will be discussed with and approved by the NYSDEC prior to implementation. Damaged monitoring wells that cannot be rehabilitated will be abandoned in accordance with the closure construction documents to prevent potential contaminant migration downward through/along the monitoring well. The monitoring well abandonment procedures will follow NYSDEC protocols and comprise the following: ♦ 131 AR0313303.DOC(R03) 3-6 • Overboring and removal of the casing, if present, to the greatest extent possible (minimum 5 feet); S Perforation of any casing remaining in the borehole; • Pressure grouting of the borehole from the base of the borehole with cement - bentonite to a depth of 5 feet below the surface using the tremie method; grout ground ® Backfilling the remaining 5 feet with native soil and compacting to avoid settlement; 0 Grouted area will be periodically inspected or possible settlement; and ® If subsequent settlement occurs, soil will be placed into the depression and repacked to grade level.

These procedures are expected to continue to be followed for all routine sampling and analysis of groundwater conducted at the landfill. Detailed sample collection and quality assurance control procedures and requirements '• are provided in Appendix B. The groundwater monitoring well network consists of six existing and six new monitoring wells at the landfill (see Figure 1-2). Groundwater sampling will be conducted oil a quarterly basis, with three of the quarters consisting of analysis for G NYCRR Part 360 Routine Parameters and one quarter consisting of analysis for Baseline Parameters. Quarterly sampling will be conducted for a minimum of 2 years. Once a baseline has been established, the results r will be evaluated to determine if the frequency, number of wells and monitoring parameters can be modified/reduced. During each sampling event, each well will be purged a minimum of three well volumes prior to sample retrieval. Either dedicated or disposable bailers will be used to collect samples after this purging procedure. Chain of custody documents for each sample I• retrieved will be maintained by both the Town and the laboratory performing the quarterly sampling and analysis. Field measurements will be obtained for temperature, conductivity and pH, and the static water level of each well will be determined prior to purging each groundwater monitoring well. I'• The results of the groundwater sample results will be provided to NYSDEC. 013141R0313304.DOC(R04) 4-1 .rr„k� Section 5 U: 5.0 LANDFILL GAS MONITORING PLAN I• The purpose of the landfill gas monitoring plan, which will be conducted on a quarterly basis for the first 3 years of the post -closure period and modified accordingly thereafter, is to detect the possible migration of methane gas across the boundaries of the site to neighboring properties before the gas becomes a hazard to the public safety. The procedure for methane gas monitoring and the Landfill Gas Monitoring Form are contained in Appendix C. Each of the 15 landfill gas monitoring wells will be monitored for the percent of methane accumulated in the well's atmosphere. The locations of these monitoring wells are shown in Figure 1-2. In addition, explosive gas monitoring will be performed at the scale house and the six gas vents located in the collection center. The results of the monitoring will be submitted to the NYSDEC. Any indication of dangerous levels of methane in the wells will be reported to the appropriate authorities for immediate action. The lower explosive limit (LEL) of methane is 5 percent, by volume, in air. When levels of methane reach 25 percent of this amount, the Contingency Plan, as described in Section 7, will be implemented. The Contingency Plan identifies the appropriate authorities to contact should excessive levels of methane be detected. Is I• s 1314\R0313305.D0QR04) 5-1 I0 Section 6 I0 6.0 PERSONNEL AND EQUIPMENT REQUIREMENTS The post -closure monitoring of the Southold Landfill will be performed by the Town of Southold personnel or subcontractors retained for this purpose. Town personnel or subcontractors retained for this purpose will be responsible for the entire site's routine operation and maintenance. In the event that a component of the landfill becomes damaged, inoperative or requires repair, the procedures outlined in Section 3 of this Manual will be followed. The personnel and equipment requirements described below represent an estimate of the time that will be required to maintain and repair the landfill closure system. This estimate assumes that major storm events (i.e., those causing extensive damage to the landfill site) will not occur during the post -closure period and that other contingencies will not occur as discussed in Sections 7 and 9 of this Manual. 6.1 Staffing Plan The personnel required to conduct quarterly inspections and perform routine maintenance and repairs will be furnished on a part-time basis. Periodic training will be provided to Town personnel to satisfy the requirements for the monitoring and maintenance activities at the landfill. Equipment needed for operations and maintenance activities will be provided by the Town on an as -needed basis during the post -closure period. For events occurring outside the scope of the routine maintenance and repair program, the guidance described in Sections 7 and 9 of this Manual will be followed. Sections 6.1.1 and 6.1.2 provide a summary of the required training for monitoring and maintenance personnel. Records will be routinely kept for Town personnel and are described in Section 10 of this Manual. 6.1.1 Staff Training Selected Town personnel should be trained on specific duties at the site. These personnel should be given additional training in the recognition of, and response techniques to first aid, confined space entry and basic firefighting. These training programs will be updated annually and as newly developed procedures are implemented. The Town's personnel training will ♦13141R0319302.doc(R04) 6-1 I0 include conducting comparative data (laboratory and field) analyses and identifying when significant changes occur in data from period to period, as well as identifying unusual occurrences. If unusual circumstances or conditions occur, the Town will make arrangements for and acquire professional assistance, if required. Evaluations of alternatives and implementation of solutions will be directed by the Town. 6.1.2 Safety Plan The Southold Landfill after closure is not expected to expose personnel to waste or hazardous substances, and routine monitoring and maintenance activities are expected to be conducted using general site safety equipment personal protective equipment under normal conditions. Health and safety procedures for the performance of routine operations and maintenance of the site are outlined in this section. A site specific health and safety plan for the closure of the landfill was prepared by the construction contractor to address the conditions associated with the construction of the landfill capping system and appurtenances. This plan is provided as a reference document and as a resource in the event that extensive or invasive activities or repairs become necessary in the future. The document may need to be updated to address the activities to be undertaken. Personnel involved in the post closure monitoring and maintenance of the landfill should familiarize themselves with the health and safety program which was implemented during closure construction, but should recognize that it represents conditions with heavy construction, earthwork and activities directly involving the excavation and relandfilling waste. Based on available information, it appears that the landfill contains the following potential chemical and physical hazards: • Methane gas; Open drainage swales; ® Large diameter drainage piping, manholes, catch basins and stilling basin; ♦1314Ut0319302.doc(R04) 6-2 0 �0 • Recharge basins; ® Severe weather; and ® Deer ticks. The items listed above are not meant to be all inclusive, but are a minimum listing of hazards which should be taken into consideration during the post -closure monitoring and maintenance period, and which should be considered in the approach taken during post -closure activities. The Town should include other hazards as it determines appropriate. The landfill personnel must be made aware of these potential hazards, given special instructions as needed, and utilize issued safety equipment (as necessary), all in conformance with the Town's health and safety program, and in conformance with the Occupational Safety and Health Administration (OSHA) requirements. IMethane Gas Methane, an odorless, colorless and tasteless gas, is an asphyxiant under high concentrations. There are no systemic effects, either at 5 percent concentration or for long-term exposure. Neither are there any OSHA Permissible Exposure Limit (PEL), National Institute of Occupational Safety and Health (NIOSH) recommended exposure limit, or American Conference of ' Governmental Industrial Hygienists (ACGIH) threshold limit values. The prime concern associated with methane is the hazard of fire and explosion. The Lower Explosive Limit (LEL) for methane is 5 percent of air volume and the Upper Explosive Limit (UEL) is 15 percent of air by volume. IPost -closure monitoring personnel must be aware of. 1) the presence of methane gas on i site; 2) the potential hazards associated with methane gas; and 3) the procedures to be followed to detect methane. Personnel must avoid generating arcs, sparks or flames in areas where methane gas is detected at levels of 10 percent of the LEL or greater and are prohibited from smoking on site. An explosive gas/oxygen analyzer will be used to detect the presence of methane gas and determine its concentration. ♦ 13I AR0319302.doc(R04) ME J �0 Open Drainage Swales/Recharge Basins There are drainage swales, approximately 2 to 3 feet deep, located throughout the landfill. Three recharge basins are located at the site. Consistent with typical industry practice, the swales and recharge basins are not fenced and, therefore, could be a potential physical hazard to personnel traveling across the site. Personnel performing inspection, maintenance or repair work at the landfill should be aware of this potential hazard and the necessary precautions needed to be taken to avoid it becoming a hazard. Large Diameter Drainage Piping, Manholes, Catch Basins and Stilling Basin Along the southwest and eastern portion of the landfill are drainage systems which includes a series of open drainage swales which discharge into a buried 24- to 36 -inch diameter gravity storm water drain. There are several manholes, catch basins and a stilling basin as part of the buried gravity storm water drain systems which provide access to the pipe system. It is expected that all of these buried structures will require periodic inspection, cleaning and maintenance. Prior to entering any of these buried structures for any purpose, it is imperative that they be tested for the presence of gases, particularly methane. Confined space procedures should be implemented by personnel when entering and working in these areas. 4 Severe Weather The Southold Landfill is open and exposed to both the sun and the wind, which can aggravate extremes of temperature. In the winter, there is little protection from the wind, and in summer, there is no screening from the sun. These conditions can potentially contribute to physical hazards, such as hypothermia, dehydration and frostbite in the cold weather, and heat rash, heat cramps, heat exhaustion and heat stroke in hot weather. Personnel performing inspections, maintenance and repair work at the landfill will be advised of the severe weather hazards and necessary precautions as part of the safety orientation program. ♦13141R0319302.doc(R04) • " L Deer Ticks 0 Personnel working at the landfill should take the precautions described below against C7 possible deer tick bites. Deer ticks are carriers of the spirochete (borrelia bergdorfi), which causes Lyme Disease, that can be transmitted to humans when bitten. Signs and symptoms of Lyme disease may include the following: • The most well-known warning sign is a rash, classically described as a small red area that starts at the site of a tick bite and gradually enlarges over several days. The rash, which does not appear until three to 30 days after the tick bite, may grow to several inches in diameter and is circular with a central clearing. It may be obvious or very faint. Multiple, usually smaller, rashes without central clearing may develop in some individuals. r • Flu-like symptoms may precede or accompany the onset of the rash. Symptoms may include chills and fever, headache, malaise and fatigue, stiff neck and, in some cases, pain in the joints. • If the initial stage is not discovered and treated promptly, later stages may develop. Chronic arthritis, and in some cases heart and nervous system disorders may develop weeks to months after the tick bites. Some infected individuals may not develop either rash or symptoms. Therefore, anyone bitten or thought to be bitten by a deer tick, or developing signs or symptoms of Lyme Disease, is advised to see a physician promptly for an examination and possibly a blood test. To prevent tick bites, personnel should wear long pants made of light-colored, tightly woven cloth; tuck pants legs inside of socks; use an insect repellant; check themselves frequently; and wash themselves thoroughly at the end of each day. • 6.2 Equipment The equipment utilized for post -closure monitoring and maintenance of the Southold Landfill will consist of standard construction equipment from the Town's inventory or from that of ♦ 1314\R0319302.doc(R04) 6_5 IL] subcontractors retained by the Town for monitoring and maintenance purposes. In addition, the Town's standard maintenance equipment, such as mowers and trimmers, will be used at the discretion of the Town to maintain the site following its closure. 6.2.1 Minimum Requirements for Maintenance The principal operations to be performed by the Town on a regular basis during the post -closure period will be maintenance of the vegetative cover and the repair of cover soil erosion. Mowing operations will require the use of a heavy equipment mower which can be operated safely on steep sideslopes. The soils repair will be accomplished with a front-end loader, a vibratory drum roller and a grader, as necessary, depending on the size and depth of the area which has been eroded. This equipment may be available in the Town's inventory or will be rented or leased, or provided by subcontractors retained by the Town for monitoring and maintenance purposes. The equipment must be outfitted with rollover protection cabs and backup alarms meeting the OSHA requirements for this type of machinery. The equipment will be maintained according to the Town's current maintenance schedule and additional equipment for emergencies should available from the inventory of subcontractors retained by the Town. Because the Town will utilize necessary additional equipment from its subcontractors, resources will not be designated solely for landfill post -closure activities at the landfill. 6.2.2 Firefighting Equipment Fire extinguishers will be carried on all equipment used on the site for maintenance or repair work. In addition, the local fire company will provide assistance and/or equipment, as needed, to control any fires which may occur at the site. ♦ 1314\R0319302.doc(R04) 4=0 Section 7 . . . . . . . . . . . .0 7.0 CONTINGENCY PLAN The objective of the Contingency Plan is to address the events which may occur outside of the scope of the routine maintenance program. The Contingency Plan will be implemented following the discovery of a condition at the landfill which cannot be covered by routine scheduled maintenance and repair. Natural occurrences, such as storms, drought and landfill settlement, are considered "expected occurrences" and have been addressed in the previous sections of this Manual. Other situations, such as war, an earthquake or other catastrophic events, cannot be reasonably expected to occur and, therefore, are not specifically addressed in this Manual. The Contingency Plan which follows addresses new degradation of the groundwater quality, the migration of methane gas and the possibility of a fire on the landfill. The guidelines which follow will be used to determine when the Contingency Plan should be implemented and which corrective measures should be implemented. The appropriate regulatory agencies and public officials will be notified of any emergency which is governed by this plan. 0 7.1 Groundwater Contamination Groundwater will be monitored quarterly during the first 2 years of post -closure period according to the provisions of Section 4 of this Manual. In the event that a statistically significant increase in the level of contamination emanating from the landfill via the groundwater pathway occurs, the Town will notify the NYSDEC. Based on this occurrence, the next round of sampling will include testing of the wells for the Part 360 Baseline Parameters. Should the elevated levels continue, or if new contaminants are discovered, a work plan may be developed that will investigate the nature, extent and cause of the contamination, including the possible installation of additional groundwater monitoring wells. Upon development of the work plan and completion of the investigation involved, a report will be prepared describing the findings of the investigation and providing ♦ 13141R0313306.DOC(R05) 7-1 U recommendations for corrective measures, if necessary. At a minimum, any corrective measure will be accomplished in accordance with 6 NYCRR Part 360-2.20. 7.2 Landfill Gas Migration Methane gas that is vented to the atmosphere does not present a risk to human health. However, migration of gas off-site and a buildup of gas within a confined space may create an explosion hazard. If it is suspected that methane gas generation poses a health hazard, the NYSDEC will be notified and an investigation undertaken to determine whether the vent system is functioning properly. The possible responses to a gas venting problem include replacing portions of the venting system, adding new vents or venting trenches, or installing an active gas withdrawal system. 0 Currently, a gas monitoring system exists along the southern, western and eastern boundaries of the landfill. The landfill gas monitoring wells are designed to detect the presence of methane migration. A description of the routine gas monitoring plan is provided in Section 5 of this Manual. In the event that methane gas is detected at a level equal to, or greater than 25 percent of the LEL (5 percent, by volume) during the monitoring period, the NYSDEC will be notified and all steps necessary will be immediately undertaken to ensure safety and protection of human health. If deemed necessary, the following will be implemented. a Within seven days of detection, the Town will submit to the NYSDEC a report of the methane gas levels detected and provide a description of the steps that will be taken to protect human health; and ® Within 45 days of detection, the Town will submit a plan to implement a remediation plan for the methane gas releases and a schedule for implementation of the plan � within 60 days after date of detection. The plan will assess the nature and extent of y the gas release problem and describe the proposed remedy. • ♦ 1314\R0313306.DOC(R05) 7-2 I9 • 7.3 Fire and Explosion 0 The Southold Landfill has been inactive since 1993. As a result, the likelihood of an I• underground fire in the waste is low. However, an aboveground (vegetation) fire is a possibility and will be reported to the local fire department immediately if it occurs. The appropriate response measure, including the safety of the personnel on the site, will be the responsibility of the Fire Department. Any damage to the landfill closure structures will be repaired according to the guidelines in Section 3 of this Manual after extinguishing the fire. 7.4 Emergency Response Emergencies are events which fall outside of the reasonable range of occurrence and have not been included in the Contingency Plan. Such events may include, but not limited to, a catastrophic failure of one of the storm water control features or a catastrophic failure of the landfill cap. 7.4.1 Notification Procedure For emergencies that present an immediate danger or threat to human health and welfare, the Police and Fire Departments will be notified, the affected area(s) secured and local residents • warned or evacuated. For emergencies that do not present an immediate threat or danger, the NYSDEC will be notified.

I0 8.0 POST -CLOSURE COST ESTIMATE • This section of the Manual provides an estimate of the costs expected to be incurred during the post -closure monitoring and maintenance of the Southold Landfill. This annual cost estimate is based on 2003 dollars and is presented on Table 8-1. The projected cost of the three • basic components (inspection, monitoring and maintenance) is presented below. The total projected cost during the 30 -year post -closure period, based on quarterly inspection and monitoring, and an escalation rate of 5 percent annually, is approximately $5,771,000. However, certain variables may affect these estimated costs: • The extent or severity of storms which exceed the design standards and result in severe erosion or other natural calamities; • Weather extremes, such as drought or extensive frozen ground; • A change in groundwater quality which could require the installation of additional monitoring wells or additional testing of the existing wells; • A change in groundwater quality which could require less testing; • Migration of landfill gas beyond the perimeter of the landfill which could require the installation of additional monitoring wells or additional testing; and • Increase in annual escalation rate, fees, special levies, changes in insurance rates or other unexpected administrative costs. 8.1 Inspection Costs It is assumed that it will take one person to perform the inspection at an hourly rate of $50 per hour. Assuming that the inspection will be performed during a 4 -hour period, this would amount to $200 per inspection. The landfill will be inspected four times per year, therefore, the annual estimated cost of performing the site inspections is estimated to be $800 per year. 0131AR0320303.DQC(R05) 8-1 1 • 0 Table 8-1 POST -CLOSURE COST ESTIMATE - ANNUAL SUMMARY Inspection $800 Routine Maintenance and Repair 18,880 Contingency Repair 4,240 Groundwater Monitoring Sample Collection 14,400 Laboratory Analysis 19,600 Gas Monitoring 8,800 Record Keeping and Report Preparation 16,000 Total $82,720 ♦ 1314\R0320303.D0QR05) i4 8-2 s '• 8.2 Maintenance Costs • Routine maintenance of the landfill cap is anticipated to include three activities: 1) repair of erosion damage to the landfill cap, drainage swales, access road and maintenance roads; 2) mowing landfill vegetation; and 3) removal of silt and debris from the drainage structures, including the gravity storm water drainage systems and recharge basins. Estimating this work requires assumptions based on previous post -closure monitoring experience, as well as a knowledge of the site weather history. Repair costs will generally involve a minimum of two workers and appropriate equipment. Routine repairs are anticipated to involve one 8 -hour day per specific component (e.g., drainage swales), and routine repair to the access and maintenance roads and landfill cover system is anticipated to take two days for each occurrence. On average, it is expected that the erosion repair and maintenance of the swales, stilling basin, manholes, catch basins and drainage outlet structures will be performed twice per year. Mowing (at the discretion of the Town) will occur once per year. Routine erosion repair of the vegetative cover and to the roads will probably occur twice per year. The cost of these maintenance services, including general site maintenance, is anticipated to average approximately $16,760 annually (see Table 8-2). The cost of this maintenance work may be greater during the first 3 years of the post -closure period as the vegetative cover develops, but is expected to decrease to a lower value for the remainder of the 30 -year post -closure period. Other costs which may be incurred during the maintenance period include groundwater and landfill gas monitoring, monitoring well repair or replacement, gas vent repair or replacement, reconstruction of drainage structures, or repairs to the geomembrane or barrier • protection cover. These costs are contingent upon need and, therefore, are unable to be estimated at this time. However, an amount equal to approximately 25 percent of the routine inspection and maintenance costs is estimated for contingencies. This amount for these non -routine (contingent) repairs is estimated to be approximately $4,240 per year. While it is not expected to be used each year, it is anticipated that over the post -closure life of the facility, non -routine repairs will occur that will necessitate the use of contingent monies. Unspent contingency budget monies should be carried over, and accrued, from year to year. ♦ 13141R0320303.DOC(ROS) 8-3 Table 8-2 ROUTINE MAINTENANCE AND MONITORING SCHEDULE ANNUAL POST -CLOSURE BUDGET ♦ 1314\R0320303.DOC(RO5) 8-4 Labor Total Sample No. of Total No. of Combined Rates Labor Equipment Equipment Analysis Samples Analysis Total Activity Personnel $/hr $/day Days/yr. $/yr, $/day $/yr. $/sample yr. $/yr. $ Landscaping • Mowing (at the Town's 1 35 280 4 1,120 500 4,000 -- -- -- 5,120 discretion) Storm Water Control Features • Swales 2 70 560 2 1,120 100 200 -- -- -- 1,320 • Recharge Basins 2 70 560 2 1,120 100 200 -- -- -- 1,320 • Stilling Basin 2 70 560 2 1,120 100 200 -- -- -- 1,320 • Manholes 2 70 560 2 1,120 100 200 -- -- -- 1.,320 Environmental Monitoring • Groundwater Sampling and 2 100 800 8 6,400 500 8,000 300 42 12,600 34,000 Analysis (first 2 years) 500 14 7,000 • Landfill Gas Monitoring 1 50 200 4 800 500 8,000 -- -- -- 8,800 Contingency Repair 2 70 560 4 2,240 500 2,000 -- -- -- 4,240 Access and Maintenance Roads 2 70 560 4 2,240 500 200 -- -- -- 4,240 General Site Maintenance 2 70 560 4 2,240 500 2,000 -- -- -- 4,240 Record Keeping and Report 1 100 800 20 16,000 -- -- -- -- -- 16,000 Preparation Total 35,520 26,800 19,600 81,920 ♦ 1314\R0320303.DOC(RO5) 8-4 n 8.3 Monitoring Costs 8.3.1 Groundwater Monitoring Twelve wells will be utilized to monitor groundwater during the post -closure period. It is anticipated that well sampling will be conducted by two field personnel, and that two (8 -hour) days will be required for collection of a complete round of samples. With four rounds of monitoring required each year, a field labor budget of $6,400 is anticipated. Groundwater sampling will be conducted on a quarterly basis, with three of the quarters consisting of analysis for Part 360 Routine Parameters and one quarter consisting of analysis for Baseline Parameters for the first 2 years of sampling. The annual budget for laboratory analyses of groundwater samples is estimated to be $19,600. An estimated cost of $8,000 per year will be �1 required to cover costs for sampling equipment resulting in a total annual groundwater monitoring budget of $34,000 per annum. 8.3.2 Landfill Gas Monitoring Gas monitoring will be conducted on a quarterly basis during post -closure period. This involves the effort of one individual for a 4 -hour day for each monitoring event. This results in a labor and equipment expense of $9,600 on an annual basis. ♦ 1314\R0320303.DOC(R05) 8-5 0 Section 9 . . . . . . . . . . . i �a 1C EI 0 9.0 COMMUNICATION PROCEDURES During the 30 -year post -closure period at the Southold Landfill, routine inspections will be performed quarterly as described in Section 2 of this Manual. In addition to these scheduled inspections, non -routine inspections may be necessary as a result of extraordinary incidences which may occur at the landfill, such as fres, natural disasters or significant vandalism. Sections 2 and 3 of this Manual identify the procedures to be followed for routine site inspections and scheduled maintenance and repair. The procedures outlined in Sections 2 and 3 will also be followed in the event that a non -routine inspection is required. This section of the Manual outlines the recommended communication procedures to be followed in the event that a component of the landfill site becomes damaged, inoperative or requires non -routine repairs. Table 7-1 lists the telephone numbers of the appropriate authorities to contact in case of emergencies. 9.1 Vandalism Routine inspection of the soil cover will reveal if any unauthorized dumping or vandalism has occurred on site. Should this occur, inspection personnel will record evidence of such activity (e.g., vehicle tracks) or attempt to identify source of the illegally placed waste and those who caused the vandalism, and immediately notify the Town. One form of vandalism that may occur on this landfill during the post -closure period will be the result of off-road vehicles using the area. These vehicles tend to damage vegetation and create ruts, possibly exposing the geomembrane and damaging it. When vandalism, trespassing or unauthorized dumping has occurred, the Town will evaluate site security procedures to identify the probable access route and will augment the security procedures to prevent such access, as needed. If the site cannot be secured through the use of existing resources, and the Town determines that additional labor or materials are needed to protect the site, the Town will obtain an appropriate commitment of specialty resources. ♦ 131AR0319303MOC(R03) 9-1 A 'i In addition, to determine if any of the landfill components have been damaged as the result of significant vandalism, an emergency site inspection will take place. The Town Solid • Waste Coordinator will coordinate and direct all emergency repairs. • 9.2 Fires All Town equipment, or equipment used by subcontractors retained by the Town, used for maintenance and/or repair work, will be equipped with fire extinguishers. However, should a fire occur which cannot be contained by on-site personnel or equipment, the local fire department will be contacted. In addition, the Town Solid Waste Coordinator will be notified immediately so that he/she can coordinate the other on-site activities. After a fire, the Town will determine if any of the landfill components were damaged. A site investigation will be undertaken according to the procedures outlined in Section 2 of this Manual. The Town will coordinate and direct all emergency repairs and notify the appropriate agencies of any adverse conditions at the site. 9.3 Natural Disasters Some natural disasters that might occur at the site may include, but not be limited to, hurricanes, heavy rains, ice storms, lightning strikes and/or floods. Other natural phenomena, such as tornadoes and seismic events, are unlikely to occur at the site due to its geographic location. Should one or more of these events take place, Town personnel (or personnel of subcontractors retained by the Town) will follow emergency procedures to ensure protection and • prevent personal injury during the event, and will notify the Town of any evident damage or threatening conditions that have been created as a result of the event. Damage that might occur as a result of such events includes erosion of the cover system and clogging of storm water • conveyance structures. Lightning strikes to trees could result in trees falling across site roadways and fire. u 0 0 ♦ 1314=319303MOC(R03) 9-2 I 0 If a severe storm event or other natural phenomena has caused significant damage to the landfill, or if the landfill has sustained significant damage, an emergency site inspection will be undertaken to determine the extent of such damage. When the Town determines that conditions are safe to inspect the site, it will dispatch a team of qualified personnel to inspect the site as described in Section 2 of this Manual. The Town will coordinate and direct all emergency • repairs and notify the appropriate agencies of adverse conditions at the site. 9.4 Vectors During site inspections, vector infestation may be evidenced by the presence of burrow holes or nests. Should infestation be discovered to pose a potential threat to the integrity of the landfill cover system or other site components, the Town will be notified of these conditions. The Town will contact an appropriate extermination service to eliminate rodents or insects, as needed. 9.5 Methane The site will be monitored quarterly for methane at 15 locations to determine the percent of methane accumulated within the landfill gas monitoring well's atmosphere. Methane gas monitoring will also be performed in the scale house and six vents in the collection center. It is expected that these procedures will be followed throughout the 30 -year post -closure period. In the event that the recorded methane levels exceed 25 percent of the lower explosive limit (LEL), contingency planning will be implemented as described in Section 7 of this Manual. 9.6 Dust Prolonged dry periods are not expected to present the same problems at the closed/capped landfill as at an operating landfill because of the presence of vegetative cover. To prevent blowing dust, the landfill cap must maintain complete vegetative cover. This will prevent the cap from desiccation under prolonged dry conditions. However, during such periods, the use of areas that are not vegetated (e.g., access roads) will be minimized. ♦ 1314\R0319303.nOC(R03) 9-3 I0 I0 9.7 Storm Water Control System The storm water control system will be inspected to determine if siltation has occurred or if debris has accumulated which would impede the flow of storm water through the p b conveyance system or recharge into the groundwater. In the event that siltation has occurred, it will be noted I�• on the inspection form and the Town will be notified so that the appropriate action can be taken to clean the conveyance system or clean the recharge basin. L NE Drainage swales of the storm water conveyance system will be inspected for excessive build-up of silt; the gravity drain, manholes, catch basins and stilling basin will be cleared of silt and other debris; and the recharge basins will be scraped to remove silt and other fine particles that would prevent or impede groundwater recharge. 9.8 Excessive Landfill Settlement The landfill will periodically be visually inspected for cap integrity and differential settlement to determine if a change has occurred which could indicate potential malfunction of one of the landfill closure components. If it is determined through the evaluation that certain areas have settled to the point where the integrity of the cap system may be jeopardized, the Town will notify the NYSDEC. Upon a physical examination of the site by the Town and the NYSDEC, a work plan will be prepared to repair any damage that may have been caused to the landfill cover system. 9.9 Groundwater Contamination Should there be a statistically significant increase in the level of contamination emanating from the site via the groundwater pathway, the NYSDEC will be notified and the Town or its subcontractor will monitor the Part 360 Baseline Parameters during the next round of sampling. Should the elevated levels continue, or if new contaminants are discovered, the Town will prepare a work plan to investigate the nature, extent and cause of the contamination. The work ♦ 1314\R0319303.DOC(R03) 9_4 '* plan will be submitted to the NYSDEC for approval. Following implementation of this work plan, the results will be evaluated and recommendations for corrective measures will be made to the NYSDEC. • u u 0 I♦ 13I4\R0319303.DOC(R03) 9-5 0 Section 10 A J f 1 r 0 10.0 RECORD KEEPING AND REPORTING 10.1 Record Keeping The Town will maintain records of inspections, maintenance (routine and non -routine), and monitoring of the landfill.

The post closure monitoring program includes groundwater monitoring. The purpose of this Quality Assurance/Quality Control (QA/QC) Plan is to develop and describe the detailed sample collection and analytical procedures that will ensure high quality, valid data for use during post closure monitoring. 1.2 Data Usage The data generated from the field sampling program will be used to evaluate the effectiveness of the landfill closure in accordance with Part 360. In addition, data will be used to monitor health and safety of workers at the site and the health and safety of persons off-site. 1.3 Sampling Program Design and Rationale The following presents a general discussion of the sampling to be conducted during year 1 of post closure monitoring. ® Groundwater: Four rounds of 12 groundwater samples will be collected. Each round will consist of one sample from each of the six newly installed wells and the six existing wells. For a discussion of the sampling program and sample locations, see Section 4.0 of the Manual. ♦ 1314\A0314302.doc(R02) 1-1 1.4 Analytical Parameters The first round of samples will be analyzed for Baseline Parameters as defined in 6 NYCRR Part 360-2.11(c)(6) "Water Quality Analysis Table" (see Attachment A). The subsequent rounds of sampling will be collected at three-month intervals and analyzed for • Routine Parameters as described in 6 NYCRR Part 360-2.11(c)(6) "Water Quality Analysis Table" (see Attachment A). If turbidity of a groundwater sample is greater than 50 NTUs, the sample will be filtered for dissolved metals analyses. In such instances both filtered and unfiltered samples will be analyzed for dissolved and total metals, respectively. Table 1-1 presents a summary of the parameters/sample fractions to be analyzed together with the sample location, type of sample, sample matrix, number of samples, frequency of sample collection, type of sample container, method of sample preservation, holding time and analytical method. 1.5 Data Quality Requirements and Assessment Data quality requirements and assessments are provided in the 6/00 NYSDEC ASP, which includes the detection limit for each parameter and sample matrix. Note that quantification limits, estimated accuracy, accuracy protocol, estimate precision and precision protocol are • determined by the laboratory and will be in conformance with the requirements of the 6/00 NYSDEC ASP, where applicable. Table 1-2 presents a summary of the data quality requirements. In addition to meeting the requirements provided in the 6/00 NYSDEC ASP, the data must also be useful in evaluating the nature and extent of contamination.

Specific analytical procedures and laboratory QA/QC descriptions are not included in this QA/QC plan, but will be available upon request from the laboratory selected to perform the analyses. The laboratory will be New York State Department of Health (NYSDOH) Environmental Laboratory Approved Program (ELAP) certified for organic and inorganic analyses, and also USEPA CLP • certified. 1.5.1 Data Representativeness • Representative samples will be collected as follows: • Groundwater (Monitoring Well) - Samples will be obtained after the monitoring well has been purged of three to five well casing volumes and field measurements (pH, conductivity, temperature and turbidity) have stabilized, or until the well is purged dry (whichever occurs first) and allowed to recharge. Samples will be collected with a dedicated polyethylene bailer. • Equipment Calibration - Field equipment used for field measurements will be calibrated daily before use according to the manufacturer's procedures. • • Equipment Decontamination - Nonsterile sampling equipment will be decontaminated prior to use at each location according to the NYSDEC approved procedures described on Section 1.8 of this QA/QC Plan. Ci 1.5.2 Data Comparability All data will be presented in the units designated by the methods specified by a NYSDOH ELAP and CLP certified laboratory, and the 6/00 NYSDEC ASP. In addition, sample locations, collection procedures, and analytical methods from earlier studies will be evaluated for comparability with current procedures/methods. 4 13141A0314302.doc(R02) 1-11 I 0 9 • 0 I 1.53 Data Completeness The acceptability of 100% of the data is desired as a goal for this project. The acceptability of less than 100% complete data, meeting all laboratory QA/QC protocols/ standards, will be evaluated on a case-by-case basis. 1.6 Detailed Sampling Procedures Groundwater samples will be collected from different locations as part of the post closure monitoring for the Southold Landfill. Sample locations will consist of monitoring wells. Sampling procedures and equipment are described in this section. A summary of the sampling program, including sample media, locations, depths, equipment, rationale and analytical parameters is provided in Table 1-3. Sample collection will be performed in conformance with procedures described in Section 1.6.3. The materials involved in groundwater sampling are critical to the collection of high quality monitoring information, particularly where the analyses of volatile, pH sensitive or reduced chemical constituents are of interest. Sterile disposable polyethylene bailers will be utilized for this project. "There will be several steps taken after the transfer of the water sample into the sample container that are necessary to properly complete collection activities. Once the sample is transferred into the appropriate container, the container will be capped and, if necessary, the outside of the container will be wiped with a clean paper towel to remove excess sampling material. The container will not be submerged in water in an effort to clean - it. Rather, if necessary, a clean paper towel moistened with distilled/deionized water will be used. The sample container will then be properly labeled. Information such as sample number, location, collection time and sample description_ will be recorded in the field logbook. Associated forms (e.g., Chain of Custody forms) will then be completed and will stay with the sample. The ■ samples will be packaged in a manner that will allow the appropriate storage temperature (4°C) ♦ 1314W0314302.doc(R02) 1-12 i Table 1-3 SOUTHOLD LANDFILL POST CLOSURE MONITORING SAMPLING MATRIX Note: No field blanks will be collected in accordance with New York State Department of Environmental Conservation guidance.

Samples will be delivered to the laboratory within 48 hours of collection. 1.6.1 Sample Identification All samples collected during post closure monitoring at the Southold Landfill Site will be labeled with a sample identification code. The code will identify the sample location, sample matrix and series numbers for sample locations with more than one sample. Samples will be labeled according to the following system: • Sample Location: - Monitoring Well "MW" • Sample Matrix: - Water "W" • Sample Number: - For circumstances where more than one sample of the same type and/or from the same location will be collected, a consecutive sample number will be assigned. • Quality Assurance/ - Trip Blank "TB" Quality Control (QA/QC): - Matrix Spike "MS" - Matrix spike duplicate "MSD" Based upon the above sample identification procedures, an example of a sample label may be: Sample Location QA/QC MW -W -1 -MS E-`-`' Sample Matrix_._--- Sample Number 1.6.2 Sample Handling, Packaging and Shipping All analytical samples will be placed in the appropriate sample containers as specified in the 6/00 NYSDEC ASP. The holding time criteria identified in Volume I for the individual methods of the ASP will be followed, as specified in Table 1-l. ♦ 13141A0314302.doe(R02) 1-14 qY A Prior to packaging any samples for shipment, the sample containers will be checked for proper identification and compared to the field logbook for accuracy. The samples will then be wrapped with a cushioning material and placed in a cooler (or laboratory shuttle) with a sufficient amount of bagged ice or "blue ice" packs in order to keep the samples at 4°C until arrival at the laboratory. All necessary documentation required to accompany the sample during shipment will be placed in a sealed plastic bag and taped to the underside of the cooler lid. The cooler will then be sealed with fiber (duct) tape, and custody seals will be placed in such a manner that any opening of the cooler prior to arrival at the laboratory can be detected. All samples will be shipped to ensure laboratory receipt within 48 hours of sample collection in accordance with NYSDEC requirements. The laboratory will be notified prior to the shipment of the samples. 1.6.3 Groundwater (Monitoring Well) 1. Be certain that the sample location is noted on Location Sketch (see Section 1.9). 2. Measure the depth of water using a decontaminated water level indicator and compute the volume of standing water in the well. 3. Remove three to five times the volume of standing water from the well until field measurements (pH, conductivity, temperature, and turbidity) stabilize, or until the well is dry, whichever occurs first, with a submersible pump. (Turbidity must be less than 50 NTUs prior to collection of a sample for metals analysis. Greater than • 50 NTUs may require filtering of the sample or waiting a maximum of 24 hours for the turbidity to decrease.) 4. Remove the laboratory precleaned sample containers from sample cooler, label container with an indelible marker, fill out Sample Information Record and Chain of Custody Form (see Section 1.9). • 5. Obtain a sample by using the disposable polyethylene bailer. The order to which the samples are collected is: VOCs, metals, cyanide, and wet chemistry parameters. I 6. If the turbidity exceeds 50 NTUs, then the well should be sampled for all constituents except metals. The well can rest for a maximum of 24 hours until a turbidity reading is less than 50 NTUs, once less than 50 NTUs, the metals sample can be collected. 7. If it is determined in consultation with the NYSDEC that filtering of the sample is necessary (i.e., through direction from NYSDEC or after waiting a maximum of 24 hours), first collect an unfiltered sample in a sample container, replace the cover on the sample container and label the sample. Next, pour an appropriate amount of the remaining sample from the bailer into a second sample container through a filter medium (0.45 microns) to remove particulates from suspension. Replace the cover on the sample container and label the sample. The turbidity of both the filtered and unfiltered sample will be recorded at the time of collection. 8. Gently pour the sample into the sample container taking care not to spill on outside of bottle or overfill container and replace cover on the sample container. Samples for volatile organic analyses, will have no air space in the sample vial prior to sealing. This is done by filling the vial such that there is a meniscus on top. Carefully, slide the septum, Teflon side down, onto the top of the vial and cap the vial. Check for bubbles by turning the vial upside down and tapping it lightly. If bubbles appear, reopen the vial, remove the septum and add more sample (or resample). Replace the • septum, recap and check for bubbles. Continue until vial is bubble -free. 9. Return sample container to sample cooler. 10. Dispose of bailer. r 11. Place disposable personal protective equipment into a 55 -gallon drum. 1.7 Decontamination Procedures • All field sampling equipment should be sterile and dedicated to a particular sampling point. In instances where this is not possible, a field cleaning (decontamination) procedure will be used in order to reduce the chances of cross contamination between sample locations. A decontamination station will be established for all field activities. This will be an area located away from the source of contamination so as not to adversely impact the decontamination procedure, but close enough to the sampling area to keep equipment handling to a minimum. 01314\A0314302.doc(R02) 1-16 1.7.1 Field Decontamination Procedures All nondisposable equipment will be decontaminated at appropriate intervals (e.g., prior aitial use, prior to moving to a new sampling location and prior to leaving the site). Different ontamination procedures are used for various types of equipment that perform the field vities as discussed below. When using field decontamination, it is advisable to start sampling :1e area of the site with the lowest contaminant probability and proceed through to the areas of lest suspected contamination. 1.7.2 Decontamination Procedure for Drilling All equipment such as drill rigs, backhoes and other mobile equipment should receive an ial cleaning prior to use at the site. The equipment will then be decontaminated prior to ling the site and each time it returns on-site. Unless otherwise specified and approved, all Wrinse solutions should be collected and contained on-site. The actual fate of this material be determined after review of analytical data generated from samples and on-site discharge acts have been evaluated. After the initial washing, cleaning may be reduced to those areas that are in close Kimity to materials being sampled. Drill rig items such as auger flights, drill rods, and drill are to be cleaned in between sample locations. All decontamination generated wastes will be contained in 55 -gallon drums and stored in designated area. Drilling equipment will be decontaminated in the following manner: Scrub all surfaces thoroughly with nonresidual nonionic anionic detergent (such as alconox) and tap water using a brush to remove particulate matter or surface film. This is necessary in order to remove any solids buildup on the back of the rig, auger flights, drill rods, drilling head, etc. Any loose paint chips, paint flakes and rust must also be removed. f 41A0314302.doc(R02) 1-17 0 • Steam clean (212°F). f 1 1.7.3 Decontamination Procedure for Sampling Equipment Teflon, PVC, polyethylene, polystyrene and stainless steel sampling equipment decontamination procedures will be the following: • Wash thoroughly with nonresidual nonionic anionic detergent (such as alconox) and clean potable tap water using a brush to remove particulate matter or surface film. • Rinse thoroughly with tap water. • Rinse thoroughly with distilled water. • Rinse in a well ventilated area with methanol (pesticide grade) and air dry. • Rinse thoroughly with distilled water and air dry. • Wrap completely in clean aluminum foil with dull side against the equipment. For small sampling items, such as scoops, decontamination will take place over a drum specifically used for this purpose. The first step, a soap and water wash, is to remove all visible particulate matter and residual oils and grease. This is followed by a tap water rinse and a distilled/deionized water rinse to remove the detergent. Next, a high purity solvent rinse is designated for trace organics removal. Methanol has been chosen because it is not an analyte of concern in the TCL. The solvent must be allowed to evaporate and then a final distilled/deionized water rinse is performed. This rinse removes any residual traces of the solvent. The aluminum wrap protects the equipment and keeps it clean until it is used at another sampling location. 1.7.4 Decontamination Procedure for Well Casing/ Screen and Development/Purging Equipment �j Field cleaning of well casing and screen should consist of a manual scrubbing to remove foreign material and steam cleaning, inside and out, until all traces of oil and grease are removed. Ifrecleaned certified well casing and screen can be obtained from the manufacturer this would p g ♦ 1314W 0314302.doc(R02) 1-18 t 1 t i oil also be acceptable. This material should then be stored in such a manner so as to preserve it in this condition. Special attention to threaded joints may be necessary to remove cutting oil or weld burn residues. Materials and equipment that will be used within the monitoring well casing for the purposes of well development and purging shall also be decontaminated. The submersible pump will be decontaminated by the following procedures: 1. Place pump in a water solution of an nonionic anionic surfactant solution (such as unscented Tide or Alconox) solution and wash the outside of the pump with a scrub brush. 2. Pump approximately five gallons of the wash solution through the pump. 3. Place pump in bucket of clean water and pump out five gallons of water. 4. Wipe down the cable with deionized water and a paper towel. 5. Decontamination water will be disposed of on-site. 1.8 Laboratory Sample Custody Procedures A NYSDOH ELAP and CLP certified laboratory meeting the requirements for sample custody procedures, including cleaning and handling sample containers and analytical equipment will be used. The laboratory's Standard Operating Procedures (SOPs) will be available upon request. r 1.9 Field Management Documentation g n Proper management and documentation of field activities is essential to ensure that all necessary work is conducted in accordance with the sampling plan and QA/QC Plan in an efficient and high quality manner.

All findings will be documented and provided to the Field Operations Manager. A copy of Field Audit form is in Section 1.23, 1.12 Control and Disposal of Contaminated Material During sampling of the monitoring wells, water will be generated from purging. Specifically, all water associated with the wells will be disposed of on-site. Decontamination water will also be disposed of on-site. In general, soiled personal protective equipment (PPE) and disposable sampling equipment (i.e., bailers, tongue depressors, scoops) will be considered solid waste and contained and disposed off-site. If hazardous waste contamination of PPE or disposable equipment is suspected, due to elevated measurements of screening instruments, visual observations, odors or other means, PPE and equipment will be drummed and secured on-site until a hazardous waste determination can be made. Once a determination has been made, an approved disposal method will be employed. 1.13 Documentation, Data Reduction and Reporting A NYSDOH ELAP and CLP certified laboratory meeting requirements for • documentation, data reduction, and reporting will be used. All data will be cataloged according to sampling locations and sample identification nomenclature which is described in Section 1.6.1 of the QA/QC plan. ♦1314\ 0314302.doc(R02) 1-25 • � �s NYSDEC "Sample Identification and Analytical Requirement Summary" and "Sample !, • Preparation and Analysis Summary" forms (for VOC Analysis, B/N-A Analysis, Pesticides/PCB Analysis and Inorganic Analysis) will be completed and included with each data package. These forms are contained in Section 1.22. The sample tracking forms are required and supplied by the 6/00 NYSDEC ASP. 1.14 Data Validation As described in Section 1.13 above, summary documentation regarding data validation will be completed by the laboratory using NYSDEC forms contained in Section 1.22, and submitted with the dataP ackag e. • A Data Usability Summary Report (DUSR) will be prepared instead of full data validation. The DUSR is prepared by reviewing and evaluating the analytical data. The parameters to be evaluated in reference to compliance with analytical method protocols include all chain -of -custody forms, holding times, raw data (instrument print out data and chromatograms), calibrations, blanks, spikes, controls, surrogate recoveries, duplicates and sample data. If available, field sampling notes should also be reviewed and any quality control problems should be evaluated as to their effect on the usability of the sample data. The DUSR shall describe the samples and analysis parameters reviewed. Data deficiencies, analytical protocol deviations and quality control problems shall be described and their effect on the data discussed. Re -sampling and re -analysis recommendations will be made, if necessary. Data qualifications are documented for each sample analyte following the NYSDEC ASP 6/00 guidelines. I• P, ♦ 11 MAII14302.dm(R021 1-26 L15 Performance and System Audits A NYSDOH ELAP and CLP certified laboratory, which has satisfactorily completed performance audits and performance evaluation samples shall be used. 1.16 Corrective Action A NYSDOH ELAP and CLP certified laboratory shall meet the requirements for corrective action protocols, including sample "clean up" to attempt to eliminate/mitigate "matrix interference." The 6/00 NYSDEC ASP protocols include both mandatory and optional sample cleanup and extraction methods. Florisil column cleanup is required for the pesticide/PCB fraction of both soil and water samples. There are several optional cleanup and extraction methods noted in the 6/00 NYSDEC ASP protocol. These include: Silica gel column cleanup, acid-base partition, steam distillation and sulfuric acid cleanup for PCB analysis. It should be noted, that if these optional cleanup and extraction methods are requested by NYSDEC, holding time requirements should not be exceeded due to negligence of the laboratory. However, subsequent to selection of the analytical laboratory for this project, a meeting will be scheduled among representatives of the NYSDEC, the Town and the laboratory to discuss these issues and establish procedures to ensure good and timely communications among all parties. 1.17 Trip Blanks (Travel Blanks) The primary purpose of this type of blank is to detect additional sources of contamination that might potentially influence contaminant values reported in actual samples both quantitatively and qualitatively. The following have been identified as potential sources of contamination: 4 13141A0314302.doc(R02) 1-27 • Laboratory reagent water • Sample containers • Cross contamination in shipment • Ambient air or contact with analytical instrumentation during preparation and analysis at the laboratory 0 • Laboratory reagents used in analytical procedures A trip blank consists of a set of 40 ml sample vials filled at the laboratory with laboratory demonstrated analyte free water. Trip blanks should be handled, transported and analyzed in the • same manner as the samples acquired that day, except that the sample containers themselves are not opened in the field. Rather, they just travel with the sample cooler. Trip blanks must accompany samples at a rate of one per shipment. The temperature of the trip blanks must be • maintained at 4°C while on-site and during shipment. Trip blanks must return to the laboratory with the same set of bottles they accompanied in the field. The purpose of a trip blank is to control sample bottle preparation and blank water quality • as well as sample handling. Thus the trip blank travels to the site with the empty sample bottles and back from the site with the collected samples in an effort to simulate sample handling conditions. Contaminated trip blanks may indicate inadequate bottle cleaning or blank water of questionable quality. Trip blanks are implemented only when collecting water samples, and • analyzed for volatile organic compounds only (i.e., baseline sampling). 1.18 Field Blank (Field Rinsate Blank)/Equipment Blank Field blanks will not be required for this project, since disposable bailers are being iutilized for sample collection. .r ♦ 1314\A0314302.doc(R02) 1-28 ♦ 1314\A0314302.doc(R02) 1-28 1.19 Matrix Spikes/Matrix Spike Duplicates and Spiked Blanks • Matrix spike (MS), matrix spike duplicates (MSD), and matrix spike blanks (MSB) samples are quality control procedures, consistent with 6/00 NYSDEC ASP specifications, used by the laboratory as part of its internal QA/QC program. The MS and MSD are aliquots of a designated sample (water or soil), which are spiked with known quantities of specified compounds. They are used to evaluate the matrix effect of the sample upon the analytical methodology as well as to determine the precision of the analytical method used. A MSB is an aliquot of analyte -free water, prepared in the laboratory, and spiked with the same solution used to spike the MS and MSD. The MSB is subjected to the same analytical procedure as the MS/MSD and used to indicate the appropriateness of the spiking solution by calculating the spike compound recoveries. The procedure and frequency regarding the MS, MSD and MSB are defined in the 6/00 NYSDEC ASP. Site specific MS and MSDs should be collected at a • frequency of one per 20 samples or every 7 days (one for each sample delivery group), for each sample matrix collected (i.e., water, soil, etc.). The laboratory is required to analyze an MSB at the same frequency as the MS/MSD. 1.20 Method Blanks A method blank is an aliquot of laboratory water or soil, which is spiked with the same I• internal and surrogate compounds as the samples. Its purpose is to define and determine the level of laboratory background contamination. Frequency, procedure and maximum laboratory containment concentration limits are specified in the 6/00 NYSDEC ASP as follows: The laboratory shall prepare and analyze one laboratory reagent blank (method blank) for each group of samples of a similar matrix (for water or soil samples), extracted by a similar method (separatory funnel, continuous liquid extraction or sonication) and a similar concentration level (for volatile and semivolatile soil samples only) for the following, whichever is most frequent: • Each case of field samples received, or ♦ 131 MA0314302.doc(R02) 1-29 ' • Each 20 samples in a case, including matrix spikes and reanalyses, or • , Each 7 calendar day period during which field samples in a case were received (said beginning with the receipt of the first sample in that sample delivery or period group), • Whenever samples are extracted. • Volatile analysis requires one method blank for each 12 -hour time period when volatile target compounds are analyzed. • • 1 r ♦ 1314\A0314302.doc(R02) 1-30 • 1.21 Field Management Forms ♦13141A0314302.doc(R02) 1-31 9 0 • Dvirka and Bartilucci CONSULTING ENGINEERS A DIVISION OF WILLIAM F.

These wells are grouped in pairs, with one well being shallow and ;erred across the water table, and the other well being screened deep just above the clay unit : underlies the landfill, with the exception of S-68916, which is screened below the water e at 103 feet, and 5-68831, which is screened below the clay unit at 190 feet. Depending on inion and ground surface elevation, the water table wells vary in depth from 27 to 77 feet iw ground surface (bgs) with the average depth being approximately 55 feet, and the deep [s (exclusive of 5-68831) vary in depth from 85 feet to 150 feet bgs with the average depth ,g about 130 feet. The locations of these wells are shown on Drawing 2. The existing monitoring wells are constructed with 2 -inch diameter PVC casing and stainless steel screens with locking steel protective surface casings. Screen lengths for the shallow wells are 20 feet, and screen lengths for the deep wells are 10 feet. These wells, exclusive of 5-68831 and 5-68916, are constructed in accordance with Part 360 requirements. (5-68831 and 5-68916 were constructed by the Suffolk County Department of Health Services in 0 the early 198Os and the construction details are not known.) As part of closure construction, ten groundwater monitoring wells at five locations will 0 need to be abandoned since they are located in areas that will be graded and capped or where maintenance access roads are planned to be constructed. These wells are MW -2S and 2D; MW - 3S and 313; MW -6S and 6D; MW -7S and 713; and 5-68831 and 5-68916. Well abandonment will be in accordance -with Part 360 procedures contained in 360-2.11(a)(8)(vi). After the cap • t and maintenance roads are constructed, six of the ten monitoring wells will be replaced with new • wells at approximately the same locations as the abandoned wells and constructed in accordance with Part 360-2.11(a)(8). Monitoring wells MW -2S and 2D will not be replaced since well clusters MW -4 and MW -5 will effectively monitor groundwater quality downgradient of the MW -2 cluster, and ♦ 13141G0820801.DOC(R02) 9-1 monitoring wells MW -7S and 7D will not be replaced since they are located upgradient of the `area of waste and historically have shown littletbackground contamination. Locations of the replacement wells are shown on Drawing 3. Each new groundwater monitoring well will be constructed in a drilled borehole approximately 8 inches in diameter. Drilling will be performed with hollow stem augers. The •- wells will be constructed of a 2 -inch diameter Schedule 304 stainless steel screen and threaded, flush joint Schedule 40 PVC casing. Ten feet of stainless steel wire wrapped screen with 0.02 - inch openings will be installed in each deep borehole, and 20 -foot screens will be installed in each shallow borehole, 5 feet above the water table and 15 feet below. The PVC riser will • extend from the top of the screen to 21/2 feet above ground surface and will be contained in a steel protective casing with a locking cover. The annulus of the borehole in the area of the screen will be sand -packed to a height of 2 feet above the screened interval with No. 1 Grade clean silica sand. A finer grained No. 00 sand pack material (100 percent passing the No. 30 sieve and less than 2 percent passing the No. 200 sieve), 6 inches in thickness, will be placed on top of the sand pack between the sand and the bentonite seal. A 3 -foot seal of bentonite pellets or slurry will be placed immediately above the filter material and 6 inches of No. 00 Grade silica sand pack will be placed above the bentonite seal. The remaining annulus will be grouted to the surface with cement/bentonite grout. The • bentonite will be tested and/or warranteed to be free or organic and inorganic contaminants. All material placed in the annulus of the borehole will be installed using a tremie pipe. • A 4 -inch diameter protective outer steel surface casing with locking cover and a surface cement pad will be installed around each well casing/riser.
