The 837.8 acre parcel has been owned by Dare County since September 15, 1987. The transfer station resides on approximately 5 acres of this property. A copy of the registered deed is provided in Appendix A. The site consists of a transfer station, maintenance building, scale house, C&D landfill, borrow pit, and gravel and asphalt access roads as shown on the Facility Plan sheet provided in Appendix B. 1.3 Facility Description Operations at the Dare County Transfer Station began in December 2006 under Facility Permit No. 28-05T. Dare County contracts with Bowen Company, Inc. to operate the transfer station and to transport waste to the East Carolina Environmental Landfill (Permit No. 0803-MSWLF-1993) located in Bertie County. Section 1 • Introduction 1-3 Waste from residential, commercial, and industrial sources collected from routes in Dare, Hyde, and Tyrrell counties can be accepted at the station. The waste is transported to the transfer station by private haulers, County-owned collection vehicles and County residents. C&D waste collected in Tyrrell County can be comingled with MSW at the transfer station and disposed of at the East Carolina Environmental Landfill. The transfer station processed approximately 52,815 tons of waste from July 1, 2015 through June 30, 2016. The total tonnage processed includes 52,815 tons of waste received from Dare County and 0 tons of waste from Hyde County. The station receives approximately 170 tons of waste per working day and processes an average of approximately 4,400 tons per month. Vehicles entering the transfer station are directed by a station attendant. Waste is dumped onto the tipping floor and heavy equipment is used to push the waste through chutes where it is deposited into transfer trailers located in one of two loading bays on the lower level of the building. 1.4 Contacts The primary contact for the transfer station is the Transfer Station Supervisor. Contact information for the Transfer Station Supervisor and Public Works Director are provided below: Mr. Clyde Gard, Transfer Station Supervisor (252) 475-5880 Dare County Public Works Department Mr. Edward Mann, Public Works Director (252) 475-5888 Dare County Public Works Department The physical address for Mr. Gard and Mr. Mann is: Dare County Public Works Department 1018 Driftwood Drive Manteo, North Carolina 27954 The Transfer Station Operator is: Bowen Company Inc.

Recyclable materials are separated and are not allowed to stay on the tipping floor for more than 48 hours or two business days. The following recyclables are extracted from the waste prior to loading it in transfer trailers for management: Tires; Concrete (including reinforced and unpainted concrete); Asphalt; and Metals (propane tanks, drums, white goods, and other). Tires separated from the MSW are stockpiled adjacent to the transfer station building. Dare County personnel transport the tires to the Dare County Recycling Center located at 1018 Driftwood Drive, Manteo, North Carolina. The tires are picked up weekly at the recycling center by a private company and disposed of at a processing plant located in Waverly, Virginia. Concrete and asphalt is separated from the MSW and temporarily stockpiled on the tipping floor. A front end loader or similar piece of equipment is used to transport the concrete and asphalt to a storage area located at the end of Cell 4 of the C&D landfill adjacent to Link Road. A private company is contracted to crush the concrete and asphalt as needed. The County uses the processed concrete and asphalt for roadway fill at the adjacent C&D landfill and for other projects throughout the County. Metals are separated from the MSW and stockpiled on a gravel pad adjacent to the fenced perimeter of the transfer station. Metal recyclables include propane tanks, drums, white goods, and other similar type metals. Dare County employees inspect each propane tank that is collected for recycling to confirm the tank is empty. Following inspection, the tank valve is removed. Metal barrels and drums are only recycled if they are free of liquid and are perforated to ensure that no liquid or hazardous waste is contained therein. Recyclable metals are transported to the Dare County Recycling Center by Dare County employees, where the materials are separated and collected by private companies for recycling. White goods are collected by United Salvage & Auto, Inc. United Salvage & Auto, Inc. is responsible for the removal of Freon from white goods. Stockpiled metals are not allowed to remain on site for more than 30 days prior to transporting them to the Dare County Recycling Center. Section 2 • Waste Acceptance Criteria 2-2 2.2 Prohibited Wastes The following wastes are prohibited at the Dare County Transfer Station: Hazardous Waste; Containerized or Bulk Liquid Waste; Infectious Waste; Medical Waste; Animal Waste; Electronics; Animal Carcasses; Radioactive Waste; Land Clearing and Inert Debris (LCID); Wood Pallets; and Asbestos. Wood pallets, LCID, and electronics are separated from MSW at the transfer station when spotted by transfer station personnel. Wood pallets and LCID waste are transported to the adjacent C&D landfill for disposal. Electronics are stockpiled adjacent to the transfer station building and are transported by Dare County personnel to the Dare County Recycling Center where a private company collects them for recycling. Signs are posted at the facility entrance and at the perimeter entrance gate to the transfer station warning customers that hazardous waste is not accepted. A report identifying the waste type and hauler will be prepared for any attempted delivery of a prohibited waste. The report will be submitted to: Mr. Ray Williams Environmental Senior Specialist North Carolina Department of Environmental Quality Washington Regional Office Solid Waste Section 943 Washington Square Mall Washington, North Carolina 27889 (252) 948-3955 2.3 Prohibited Wastes – Contingency Plan Every effort will be made to preclude acceptance of prohibited wastes through education and inspection, but in the case of inadvertent receipt of these wastes, personnel will be available to Section 2 • Waste Acceptance Criteria 2-3 isolate the material; return the waste to the generator or removing it for appropriate disposal; and notification to the regulating authorities immediately. In the event hazardous materials are disposed, the initial response will be from the Dare County Haz-Mat team by calling 911. Section 2 • Waste Acceptance Criteria 2-4 This page intentionally left blank. 3-1 Section 3 Transfer Station Operations 3.1 Hours of Operation The Dare County Transfer Station operating hours are Monday through Friday from 7:00 a.m. to 5:00 p.m. and Saturday from 7:00 a.m. to 12:00 p.m. The transfer station is closed on Sundays and on the following holidays: Thanksgiving Day, Christmas Day, and New Year’s Day. A sign is posted near the facility entrance identifying the hours of operation. The transfer station operating hours are subject to change and special circumstances may cause temporary closure. In the event of a hurricane, transfer station operations will cease to prepare for the impending storm. 3.2 Operating Equipment and Personnel The transfer station utilizes the following equipment for operations: Weight Scales and Associated Software; Front End Loader; Two (2) Backhoes; Two (2) Yard Dogs (i.e. small tractor trailers used to position transfer trailers on site) Transport Tractor Trailers; and Four to eight (4-8) 48-foot Transfer Trailers. All pertinent personnel operating the transfer station have completed a training course in compliance with G.S. 130A-309.25. A trained employee will be onsite during hours of operation to oversee facility operations. The number of personnel and their title used to operate the transfer station are: Title Number of Personnel Transfer Station Supervisor 1 Transfer Station Attendant 1 Scale House Operator 1 Equipment Operators 6 Section 3 • Transfer Station Operations 3-2 3.3 Operating Procedures All vehicles delivering waste to the facility are directed to the scale house for weighing. Once vehicles are weighed they are directed west along Cub Road to the transfer station entrance on the left. Vehicles entering the transfer station follow the access road to the tipping building access apron. The tipping building apron provides access to the south side of the transfer station, which opens to the 14,000 square foot tipping floor. The tipping building has 10-foot high push walls running along the interior walls and in the center that allow equipment operators to push waste to chutes feeding transfer trailers located in bays on the lower level of the building. The building is divided into two separate tipping areas that are used to process waste. The County may use one of the two tipping areas for MSW and the other for processing a different waste stream (e.g. LCID) should the County choose to modify its current waste acceptance policy. Approval will be obtained from the NCDEQ Solid Waste Section prior to implementing any changes to the current waste acceptance policy. The transfer station operator will direct vehicles waiting to unload onto the tipping floor. Adequate area is available at the tipping building access apron for drivers to queue their vehicles into a backing maneuver. Transfer station personnel are on the tipping floor to guide each vehicle to a designated area for unloading. Each load of waste is inspected for recyclables and prohibited wastes. Prohibited wastes are outlined in Section 2.2. Inspected waste is directed to a chute using a front end loader or similar piece of equipment, where it is deposited into a transfer trailer. 3.4 Waste Screening Operations Access to the transfer station is controlled at the scale house. All waste entering the station must pass the scale house before entering the tipping floor. Each load is subject to visual inspection for prohibited waste at the scale house. Loads are visually inspected by transfer station personnel as they are discharged onto the tipping floor. Should prohibited waste be identified, transfer station operations will be terminated; and material from the hauler will be reloaded onto the vehicle and removed from the facility as practicable. Reporting of the illicit event will be recorded and reported as defined in Section 2 of the Operation Plan. 3.5 Windblown Litter Control All collection vehicles with waste are required to have their loads covered upon arrival at the scale house or fully enclosed to minimize windblown litter. Outbound transfer trailers are also required to cover their loads. The transfer station is enclosed on three sides, which minimizes windblown litter. Throughout the day and at the end of each day, the transfer station operator observes the area for windblown litter. Windblown litter discovered throughout the day is placed in on-site trash bins. Occasionally, Dare County uses inmates from the Tyrrell Prison Work Program to assist with the collection of windblown litter. 3.6 Maintenance General facility maintenance is performed, as needed, outside of normal operating hours. 4-1 Section 4 Erosion Control All unpaved areas are maintained to promote a healthy stand of vegetative cover to minimize erosion. Stormwater drainage and control is discussed in Section 5. Section 4 • Erosion Control 4-2 This page intentionally left blank. 5-1 Section 5 Leachate and Stormwater Control 5.1 Leachate Control The transfer station wastewater collection system drains by gravity piping to a 2,000 gallon underground storage tank (UST) where small debris mixed with the leachate is separated by baffles, which are cleaned as necessary. The leachate then flows to a 500 gallon UST with a grinder pump installed to remove debris prior to being pumped to a 10,000 gallon above ground storage tank (AST). A tank high water level alarm (visible and audible) is automatically activated when the liquid volume in the AST reaches approximately 8,000 gallons. The tank alarm system is located in the office of the transfer station building. The AST is located inside a concrete containment wall to prevent leaks or overflows from discharging to the ground surface. The AST is inspected daily by Dare County personnel. The County contracts with a licensed private disposal company to collect and transport the leachate to a treatment plant located in Elizabeth City, North Carolina. In general, the County schedules the wastewater to be collected when the liquid volume in the AST is at 5,000 gallons. 5.2 Wash Water Control Water used for cleaning activities at the transfer station is pumped from a pond adjacent to the scale house. A transfer pump is located in a grassed area inside of the fenced perimeter of the transfer station. The tipping floor and lower level loading bays are washed down periodically throughout the day and cleared of all waste at the end of each day for a final wash down. Wash down water used to clean the tipping floor is collected by trench drains located at the tipping floor entrance. Wash down water used to clean the transfer trailer loading bays is collected by a grated floor drain located near the middle of each bay and trench drains located at the entrance and exit of each bay. All wash water is conveyed to the transfer station wastewater collection system. 5.3 Stormwater Control Site grading conveys stormwater away from the transfer station operations and into rip-rap protected grate drains located around the perimeter of the building. Roof drains also collect and convey stormwater from the covered transfer station into the perimeter drains. The perimeter storm drains are connected to piping that discharge into drainage ditches located adjacent to the fenced perimeter of the transfer station, which ultimately convey stormwater to adjacent canals. Cleanouts are installed along the stormwater piping to remove accumulated debris as necessary. The stormwater conveyance system reduces the potential of waste coming into contact with stormwater and minimizes leachate generation. Incidental stormwater entering the transfer station is collected in the leachate collection system. Section 5 • Wastewater and Stormwater Control 5-2 This page intentionally left blank. 6-1 Section 6 Disease and Vector Control The Dare County Transfer Station provides effective vector control measures for the protection of human health and the environment. Disease vectors are defined as any rodent, flies, mosquitoes, or other animals, including insects, capable of transmitting disease to humans. Control of disease vectors shall be maintained by implementation of a daily cleaning program, which involves removal of waste, leachate, and ponded water from the facility operating areas. The complete removal of waste at the end of each operating day will deter vectors from entering the transfer station. The transfer station shall utilize wash water to keep the tipping floor and loading bay areas clean and free from rodents, flies and other vectors. Ponded water shall be prevented to control mosquito breeding. The County will contract with a licensed exterminator as necessary to aid in the control of vectors. Additional operating procedures that minimize vectors include: Full or partially loaded transfer trailers are covered if left on site overnight; Transfer trailers are not parked overnight outside of the fenced perimeter; Full transfer trailers are not left on site for more than 48 hours; and Waste is not stored on the tipping floor after operating hours. Six industrial ventilation fans are installed at the transfer station to reduce the nuisance odors and help mitigate vector problems. Section 6 • Disease and Vector Control 1-2 This page intentionally left blank. 7-1 Section 7 Sign and Safety Requirements 7.1 Sign Dare County has posted various signs at the facility entrance, scale house, and transfer station to inform and direct waste haulers. A general summary of the posted signs and their locations is provided below. Facility Entrance No fire arms, drugs, or alcoholic beverages are permitted on the property Transfer station and C&D landfill permit numbers and hours of operation No hazardous waste or liquid waste accepted After hours emergency contact numbers Scale House Transfer station and C&D landfill tipping fees Warning for all waste haulers to stop at the scale house Speed limit Transfer Station Empty trailer parking No hazardous waste accepted (English and Spanish) Transfer station traffic direction Warning to not enter the transfer station until directed by the attendant Non-potable water Fire extinguisher Warning of open pit hazard Authorized personnel only 7.2 Open Burning of Waste Open burning of waste is prohibited at the Dare County Transfer Station. Section 7 • Sign and Safety Requirements 7-2 7.3 Fire Control The transfer station is equipped with fire suppression equipment to control accidental fires. The building is equipped with 5 hose bibs for water supply access and 4 fire extinguishers. Four of the hose bibs are located at each corner of the building and one is located on the center of the north wall. Three of the fire extinguishers are located on the tipping floor and one is located in the office. In addition, each piece of equipment used at the transfer station is equipped with a fire extinguisher. Fire extinguishers are inspected monthly by Dare County personnel and yearly by a private company. Inspection dates are noted on each fire extinguisher. By keeping the transfer station clean and providing visual inspections of all incoming loads, the potential for fires will be minimized. Burning loads will be extinguished before dumping, if possible. If burning materials are unloaded at the facility, the waste will be segregated from other incoming waste. In the event of a fire, the local fire department will be notified immediately by dialing 911. Firefighting services will be provided by the local Manns Harbor Volunteer Fire Department and by the Roanoke Island Fire Department. A mutual aid agreement is in place with other fire departments should the County require additional assistance. Fires that occur at the Dare County Transfer Station require verbal notice to the NCDEQ Solid Waste Section within 24 hours and written notification shall be submitted within 15 days. Verbal and written notification shall be submitted to the Washington Regional Office: North Carolina Department of Environmental Quality Washington Regional Office Solid Waste Section 943 Washington Square Mall Washington, North Carolina 27889 (252) 946-6481 7.4 Inclement Weather Inclement weather will be considered on a case by case basis and if operations cannot be performed as required to safely transfer waste material, the facility will be closed. An emergency generator is located adjacent to the transfer station and is used during power outages. 7.5 Equipment Failure Routine maintenance is performed on all equipment to minimize downtime. In the event of equipment failure, back-up equipment may be obtained from other facilities owned by the County or from a local rental company. 8-1 Section 8 Access and Security Requirements 8.1 Transfer Station Access and Security The transfer station is secured by means of access gates and fences to prevent unauthorized entry. All vehicles delivering waste to the transfer station are required to enter and exit through access gates. In addition, an access gate is located near the scale house at the entrance to the property. The access gates are locked during non-business hours. Unauthorized vehicle and pedestrian access to the facility is prevented around the remaining portion of the transfer station building by a six-foot-high, barbed wire, chain link fence. Truck drivers picking-up transfer trailers are the only authorized personnel to be on the property during non-business hours. 8.2 Attendant The Dare County Transfer Station has a full-time scale operator located in the scale house during operating hours. In addition, a transfer station attendant will be at the facility at all times during operating hours. Both the scale operator and transfer station attendant are responsible for verifying that all vehicles comply with the permitted operational requirements. 8.3 Access Road The access road for the Dare County Transfer Station is constructed of asphalt and is maintained in good condition.
