INTRODUCTION AND BACKGROUND This transfer station operations plan has been created on behalf of the Duplin County Department of Solid Waste for the Solid Waste Handling and Transfer Facility (Permit 31-03T). Operations for this facility will be conducted in accordance with this plan, the North Carolina Waste Management Rules, and generally sound environmental and waste management practices. The MSW transfer facility accepts waste from Duplin County and transports its waste to the Sampson County Disposal Inc. Landfill in Roseboro, NC, which is a lined waste management facility (Permit number 82-02). Closure of the transfer station will commence at such time as determined by Duplin County, and in conformance with this plan. Zoning approval was acquired when the MSW transfer facility was originally permitted in 1993. I1i V.T1110 Y 11•/ 1C1Zflr I Dlei The Duplin County MSW Transfer Facility is located near Rose Hill, North Carolina. The facility, which is owned and operated by the County of Duplin, is located approximately 4 miles northeast of Rose Hill, NC on Landfill Road (SR 1918). The physical address is as follows: Duplin County Transfer Station 325 Landfill Road Rose Hill, North Carolina 28458 The mailing address is as follows: Duplin County Transfer Station PO Box 976 Kenansville, NC 28349 III.

FACILITY DESCRIPTION The main MSW transfer station structure is a metal building constructed on a concrete slab and retaining wall. It is enclosed on three sides, keeping one open facade that provides accessibility for incoming vehicles. One of the enclosed sides provides an entrance for service vehicles to the tipping floor. The tipping floor encompasses an area of approximately 10,000 square feet (100 feet by 100 feet). Transfer trailers are positioned in a loading bay under the tipping floor. Incoming loads are discarded onto the concrete tipping floor where they are compacted into the transfer trailer located on the lower level. Leachate that is generated from normal activities and from regular washing of the tipping floors is collected through drains in the lower -level floor. These drains empty into the on -site holding tanks which will be pumped out by a licensed septage hauler and disposed at Shamrock Environmental Corp., Brown's Summit, NC. Any solid waste not removed from the transfer station will be stored in an enclosed transfer trailer overnight. V. SOURCE, TYPES, AND QUANTITIES OF WASTE The source of municipal solid waste will be from residential, commercial, and industrial facilities located within Duplin County. The MSW handling and transfer facility will be used solely for the handling and conveyance of municipal solid waste generated within Duplin County. The Facility will only accept solid waste as defined in G.S. 130A — 290(35). Any hazardous, liquid, or other prohibited materials found in the waste stream shall be removed and held for proper disposal. The waste will be transferred to the site in publicly and privately owned vehicles of various types and sizes. July 1, 2021, through June 30, 2022, 45,221.92 tons of MSW was accepted at the Duplin Transfer Station, which equates to approximately 3,768.5 tons per month. This equates to approximately 28.99 (-29) tons of waste per day based on a five-day work week. This rate is expected to remain relatively constant relative to population growth. Thus, a proportional increase in waste quantities should be expected as Duplin County's population increases. VI. OPERATIONS PLAN A. General The Duplin County Transfer Station will be open Monday through Friday from 7:00 AM until 5:00 PM. The facility will be closed in the observance of the following holidays: New Year's Day, Martin Luther King Jr. Birthday, Good Friday, Memorial Day, Independence Day, Labor Day, Veterans Day, Thanksgiving Holidays, and Christmas Holidays. Waste collection and transportation vehicles are weighed in at the scale house and again weighed upon departure. Signs are posted directing traffic to the proper areas for disposal of the respective material. MSW is unloaded onto the tipping floor, where it is gathered and moved into the transfer trailer. Waste is screened as it comes into the transfer station to prevent banned items from entering the facility. Wastes containing hazardous wastes, polychlorinated biphenyls (PCB's) or asbestos containing wastes are not accepted for disposal. The scale house operator will keep a log of all the daily activities. The station operator, who is responsible for observing the contents of each load, will take action if unsuitable waste is received. If a banned waste item is brought to the facility, the person responsible for bringing the waste is directed to remove it from the facility, and taken away for proper disposal, or has the option of the solid waste department staff removing the waste at an additional charge. Other activities that occur at the transfer facility include: - Duplin County accepts used tires daily. Tires are stacked by the public into the storage trailer. When the trailer is full, the County will contact Central Carolina Tire and have it switched out. A recycling warehouse is on site to process source separated recyclable materials for market. Used lead -acid batteries are collected in a designated location. These batteries are stored on a wooden pallet adjacent to the recycling warehouse. In general, the batteries are removed monthly. Yard Waste such as grass clippings, leaves, brush, and other debris (excluding pallets) is disposed of in the permitted area. Old Metal materials and appliances are collected in an area designated for metals. These materials are generally processed and removed every two months or as needed. White Goods, which contain Freon, are collected by the facility and stored in one designated area in the metal storage area. The freon is properly removed, and the discarded materials are removed every two weeks by Encore Recycling. The handling and disposal of these items are governed by 40 CFR 82 "Protection of Stratosphere Ozone". - The Scale house and Office are open during standard operating hours. Vehicles transporting MSW will stop at the scale house for weighing before and after trips to the transfer station. B. Equipment The equipment used at the MSW Transfer Station, is owned and operated by Duplin County. County personnel will conduct preventive and other maintenance to ensure the equipment remains in good operational condition. The following equipment will be used at the transfer station: - 1 CAT-926M Wheel Loader - 1 CAT-963B Track Loader - 1 JCB Backhoe - 1 Bobcat Skidsteer - 1 CAT Skidsteer - 13 Open -Top Transfer Trailers - 5 Road Tractors - 1 Yard Tractor - 4 Roll -off Trucks - 5 Pickup Trucks A wheel loader will collect the waste from the facility's tipping floor where it is then compressed and loaded into trailers located in the lower level of the transfer station. Based on the current waste volume rates, the transfer station can be managed with one wheel loader and the yard tractor. However, if the rates increase substantially, the County will rent another loader for the duration of the increased volume or until another loader is acquired (if high rates persist). C. Personnel County staff will be present at the scale house to weigh vehicles in and out. Trained staff will also be stationed at the transfer areas to oversee operations to ensure no hazardous or prohibited waste enters the transfer facility. All employees will be routinely trained in safety issues such as recognizing and managing hazardous waste, fire prevention and firefighting, and other emergency and safety related topics. Staff will receive no less than eight (8) hours of training updates annually that includes review of the operations plan and permit documents. Documentation of the training will be maintained in the operating record and be made available to the DWM upon written request in accordance with 15A NCAC 13B .0405 (a)(7). A qualified person will conduct training. First aid supplies and training will be provided in the facility. All employees will be required to immediately report all work -related injuries and illnesses. All staff members will be provided with the necessary safety equipment including gloves, dust masks, safety shoes, earplugs, safety glasses and related protective items as needed. D. Waste Transfer All vehicles will be weighed at the scale and then proceed to the transfer station or appropriate location. A two-lane all-weather access road will be maintained between the scale house and other structures. Vehicles hauling MSW will back up to the transfer stations loading bay and unload onto the tipping floor over the facility's dock. A visual inspection will then be performed by the transfer station attendant to ensure only authorized waste is accepted. Random waste screening will also be conducted in accordance with the rules as described below in F. Hazard and Nuisance Control. A wheel loader will then push and compact the waste onto the transfer trailer through the loading bay. Once full, the transfer trailer will transport the waste to the Sampson County Disposal, Inc. Landfill near Clinton, NC and an empty trailer will replace the departing trailers. Outgoing trailers will then be weighed at the scale house for bookkeeping purposes and to ensure no overloaded vehicles will enter NC roads. Weight records of MSW will be maintained at the facility and will be used in preparation for the annual reports submitted to NCDEQ Division of Waste Management. E. Leachate Management The tipping floor will be cleaned daily by using a push broom. The tipping floor, push walls and truck loading areas will be pressure washed at least monthly. The remainder of the facility including the building structure will be pressure washed no less than twice per year. Records of the pressure washing activity will be maintained at the facility. Leachate generated as a result of daily operations and periodic cleaning or pressure washing of the facility will be collected by a drain in the lower loading bay. These drains are then piped into a series of solids and grease/oil separators prior to entering the two 2,500-gallon onsite holding tanks. The volume in the holding tanks will be monitored and the tanks will be pumped out as needed, and hauled to Shamrock Environmental Corporation's wastewater treatment plant. In accordance with 15A NCAC 13B .0405(c), all vehicles and containers used for the storage or transportation of waste will be maintained to be leak resistant or stored such that no leachate will be released from the vehicles or in a manner that provides for the capture of leachate to prevent its release into the environment. F. Hazard and Nuisance Control Hazard and nuisance control for a MSW transfer station is vital for proper management and efficient operation. The attributing factors to any waste transfer process include prohibited or unauthorized waste materials, fire, odors, disease, vectors, noise, dust, and litter. The Material Screening process conforms to 15A NCAC 13B.0405(a)(8). Key elements of this plan consist of a. Training of facility personnel to recognize regulated hazardous and unacceptable waste, including asbestos materials b. Visual inspection of each load that comes into the facility, as well as random checks of loads. c. A contingency plan to correctly manage any proscribed waste. Training of Facility personnel: Anyone working at the scale house and/or transfer station will be trained to identify suspicious, hazardous and unacceptable wastes based on visual and odor characteristics. The Operations Manager or any personnel trained to identify and manage hazardous and liquid wastes will administer inspections. Transfer station employees will be SWANA certified Transfer Station Operations Specialists. All staff will be provided no less than 8 hours of training updates annually that includes a review of the operations plan and permit documents in accordance with 15A NCAC 13B .0405(7). Visual inspections: These shall include observations of each truckload at the transfer station, unloading their shipment onto a concrete pad, and observations before loading onto the processing area. The truck and driver will be detained if objectionable material is found during the unloading process. Random load inspections: Random waste screenings will be conducted by properly trained personnel who will visually inspect the incoming loads weekly at a rate of no less than 5% of the average daily waste tonnage based on the previous year's annual report as required by 15A NCAC 13B .0405 (a)(8). Records of the random screening will be kept on file, and made available during an inspection. Methodology for choosing the loads to be examined will be based on: - The probability that a load may contain proscribed waste based on type of business served or type of hauler involved. - A random selection process that will ensure any load can be checked. - The ability to distinguish and check "suspicious" loads. The shipment will be examined for prohibited and/or hazardous waste: - Asbestos containing material - Containers with hazardous labels or markings - Polychlorinated Biphenyls (PCB's) - Container with liquids, oils, paints, varnishes, etc. - Drums or commercial sized containers - Material with "chemical odors", dust, powders, smoke, or vapors - Materials with bright or unusual colors - Regulated biochemical waste - Sludges, biomass, etc. - Waste banned from landfill disposal by North Carolina statute Fire: The MSW transfer station and associated buildings will be equipped with fire extinguishers. Qualified personnel will conduct routine inspections of the fire prevention equipment. A qualified person will train all staff members in effective firefighting procedure and fire prevention. There shall be no flammable liquids stored in or around the MSW Transfer Station. A hose and water supply will be provided inside the facility for firefighting measures, and in the case of a fire, the local Fire Department will be contacted by calling 911. In the event of a fire at the site, the County will verbally notify the DWM within 24 hours of the fire and submit a written report of the fire within 15 days. The report shall include the information specified in 15A NCAC 13B .0405(a) (3)(D). Litter: The implementation of covered transfer vehicles, staff supervision, and a fenced facility will be used to prevent litter. Windblown material, if any, will be picked up and discarded daily. Odors and Vectors: Measures to be taken to control odors and disease vectors include immediate removal of waste, monthly pressure washing of the tipping floor, push walls and truck loading bays, and covering of any partial loads which may remain outside overnight. If vectors are discovered, adequate extermination measures will be taken. The tipping floor and area surrounding the push walls will be empty and clean at the end of each working day. Dust: The access roads and the areas adjacent to the MSW Transfer Station are paved to help lessen the problems associated with dust. Noise: The tract of land on which the MSW Transfer Facility is located has ample buffer to soften most noise pollution. Current levels are not expected to change. G. Operating Record and Record Keeping Hard copies of daily transactions at the Transfer Station are kept in files at the Scale House. Electronic data is retained on a computer at the Scale House The operating record will contain the following information: 1. Records of waste inspections, screenings, rejected wastes, monitoring results, certifications of training, and training procedures required by the rules at 15A NCAC 13B .0400; 2. Amounts by weight of solid waste received at the site including county and state of generation, in accordance with G.S. 130A-309.09D; 3.
