This Operations Plan has been prepared in accordance with the North Carolina Solid Waste Rules 15A NCAC 13B .0402, Operational Requirements for Transfer Facilities. The Operations Plan also addresses pertinent operational requirements outlined in Rule .0505, Operational Requirements for Sanitary Landfills. The Operational Plan will discuss the following issues: ■ Waste Acceptance Criteria ■ Facility Operations ■ Erosion Control Requirements ■ Drainage Control and Water Protection ■ Disease and Vector Control ■ Sign and Safety Requirements ■ Access and Security Requirements 1.2 Facility Location The proposed Henderson County Transfer Station will be located near the scale house on the existing Henderson County Landfill property. The Henderson County Landfill is located near the City of Hendersonville on Stoney Mountain Road. A location map is provided on the front of the transfer station drawings provided as part of this application. The transfer station site will occupy approximately 2.5 acres of landfill property. Henderson County began operating the landfill in 1970s and will cease operations by December 31,1997 to comply with closure deadlines for unlined landfills. The transfer station site is located in an area previously utilized for sedimentation control. The building site, which includes the tipping building and tipping building apron encompasses 0.66 acres of the 2.5 acre development. The Henderson County Landfill property lies within an R-15 Medium Density Residential zoning district. The use of this property as a landfill is considered a civic use and is permitted within the R-15 district. Therefore, the transfer station is a permitted use within this zoing district. The mailing address for the transfer facility is: 802 Stoney Mountain Road Hendersonville, North Carolina 28739 nAwake\swtrnsfr\permit I CDM Camp Dresser & McKee 1-1 Section 1 Introduction 1.3 Facility Description The Henderson County Transfer Station will consist of a tipping building, tipping building apron, and access roads. The tipping building will include upper and lower level concrete slabs with metal wall panels on three sides of the building. The east side of the building will be open for vehicle access to the tipping floor. Two exhaust fans will be installed along the west wall for odor control and air quality within the operating area. The tipping building apron and access roads will have either a stone, asphalt, or concrete paved surface. The existing landfill scale house will be used for weighing incoming vehicles. The outgoing transfer trailer vehicles will be weighed prior to exiting the landfill. A complete set of Civil and Architectural drawings have been included with this Transfer Facility Permit Application. The transfer facility was designed to operate as a tipping floor system. Wash water from the tipping floor and two driveway operations will be collected and directed to an onsite pump station. The pump station will convey the wash water, via a 2" force main, to the City of Hendersonville pump station. The owner of the transfer station will be Henderson County; and, the County will operate the transfer station. The primary contact person for issues concerning operation of the transfer station will be: Mr. Eldon Owen Director Henderson County Solid Waste Department 802 Stoney Mountain Road Hendersonville, North Carolina 28739 nAwakelswtrnsfApermit I CDM Camp Dresser & McKee 1-2 Section 2 Waste Acceptance Criteria In accordance with 15A NCAC 13B .0402(1), a transfer facility shall only accept those wastes which it is permitted to receive. The Henderson County Transfer Station will accept only municipal solid waste (MSW) (i.e., residential, commercial, and industrial waste) generated within the Henderson County service area. Based upon recent annual landfill waste disposal records, the County anticipates receiving a maximum annual tonnage rate of approximately 78,000 tons per year of MSW at the transfer station. The projected annual tonnage rate yields a daily rate of 230 tons per day based upon 312 operating days per year. The daily tonnage rate is subject to seasonal fluctuations in the amount of waste delivered to the facility; therefore, the transfer station has been designed to handle a maximum average tonnage rate of 325 tons per day to account for daily surges in waste flow. The residential waste will be transported to the convenience center located at the landfill by residential vehicles. The residential vehicles will consist primarily of pick-up trucks and cars. The transfer station will serve commercial vehicles only. 2.1 Recyclable Material Henderson County owns and operates a convenience center at the Henderson County Landfill. The convenience center accepts waste and recyclables delivered primarily by private homeowners. The Drop-off facility will continue to operate after closure of the landfill. The types of materials that will be delivered to the Drop-off facility are: lead acid batteries, yard wastes, white goods, and whole scrap tires. A trained inspector capable of recognizing hazardous and liquid wastes will be available during all operating hours. The transfer station will not handle or store recyclable materials. The County convenience center will continue to act as an additional waste screening measure for the Henderson County Transfer Station. 2.2 Prohibited Wastes In accordance with Rule .0505(10)(e), the Henderson County Transfer Station will not accept barrels and drums unless they are empty and perforated sufficiently to ensure that no liquid or hazardous waste is contained in them. In accordance with Rule .0505(11)(b), no hazardous or liquid waste shall be accepted at the transfer station. In addition, the transfer station will not accept infectious waste, medical waste, animal waste, animal carcasses, sludge, or radioactive waste. A report shall be prepared for any attempted delivery of waste of which the transfer station is not permitted to receive, including waste from outside the permitted transfer station service area. The report will be forwarded to: CDM Camp Dresser & McKee 2-1 bp0698 Section 3 Transfer Station Operations The Henderson County Transfer Station will be open to the public Monday through Saturday from 7:00 a.m. to 3:00 p.m. Henderson County contracts with private waste haulers to collect waste and recyclables from the various county convenience centers. The transfer station will be open on Sundays from 7:30 a.m. to 4:00 p.m. for the private haulers servicing the convenience centers. The transfer station will be closed on federal and legal holidays. A sign will be posted at the entrance to the transfer station identifying the hours of operation. The proper operation of the transfer station will require a sufficient number of trained personnel working in cooperation with each other. The County will operate the transfer station. Since the Henderson County Transfer Station will be operated as a tipping floor facility, the only equipment required for safe and effective operation of the facility are the rubber -tired front-end loaders, the transfer trailer trucks, and the pump station. The pump station has been designed to house two (2) pumps: one primary and one secondary. In the event the primary pump fails, the secondary pump is automatically activated and placed on line to maintain discharge of sanitary sewer. The County will be responsible for providing primary equipment, backup equipment, and equipment maintenance. 3.1 Tipping Floor Operations Collection vehicles delivering residential, commercial, and industrial waste to the facility will proceed to the scale house to be weighed. Once vehicles have passed the scale house area, they will continue along the access road until reaching the tipping building apron at the transfer station. The tipping building apron provides access to the north side of the Henderson County Transfer Station which opens to the 3,600 square foot tipping floor. The transfer station has been designed with a 10 ft. high push wall that runs along the east, south, and a portion of the west sides of the tipping floor; and, one (1) open pit (33' x 6') located at the north end of the facility approximately 14 ft. above the drive-thru areas. The transfer station attendant will direct vehicles, waiting to unload, back into the facility through the north entrance. The vehicles will back directly onto the tipping floor to an area designated by the attendant. Once the vehicle is in position and the waste has been inspected by the attendant, the waste load will be discharged directly onto the tipping floor. The Operator will continuously push deposited waste towards the open pit located at the north end of the upper level tipping floor. The lower level of the transfer station will have one (1) drive-thru area for transfer trailer truck access. The open -top transfer trailer trucks pull into the drive-thru area and align themselves beneath the open pit. Once the trailer CDM Camp Dresser & McKee 3-1 bp0698 Section 3 Transfer Station Operations truck is in position, the Operator will load and compact the waste into the transfer trailer. The lower drive-thru area has been designed to provide sufficient space for drivers to exit their vehicles; and, walk to safety in the event of an emergency. Once the transfer trailer has been completely loaded, the vehicle will be driven to either the Waste Management Palmetto landfill facility in South Carolina or the BFI Speedway landfill facility located in Cabarrus County, North Caroina for ultimate disposal. The tipping floor and drive-thru areas will be washed down periodically throughout the day and also at the end of each operating day. The current design indicates that wash down water will be collected by two (2) trench drains located on the upper level and four (4) driveway drains located in the drive-thru areas on the lower level of the transfer station. Henderson County and CDM are currently evaluating the use of paved collection channels (on the upper and lower levels) instead of trench and driveway drains for the collection of leachate. The final system (drains or channels) will effectively collect and treat leachate separately from stormwater. The wash down water will ultimately drain into a 6" sanitary sewer line that connects to an onsite pump station located on the south side of the transfer station. The pump station ultimately discharges to the City of Hendersonville wastewater treatment plant. A complete set of architectural, structural, plumbing, and HVAC drawings, which provide plan and sectional views of the tipping floor and drive-thru areas, have been provided with this operational plan report. CDM Camp Dresser & McKee 3-2 bp0698 Section 4 Erosion Control Requirements The Henderson County Landfill has an existing erosion and sedimentation control plan for the proposed location for the transfer station. The landfill area has several drainage ditches and sediment ponds which convey and filter sediment - laden stormwater runoff. The Henderson County Transfer Station site is located near an existing sediment pond and a proposed sediment and stormwater pond will be constructed as permitted. Stormwater runoff from the transfer station will be diverted to two (2) drop inlets located on the east and west sides of the building. Reinforced concrete pipes (RCP) encased in concrete carry the stormwater under the access roads to a proposed rip rap lined ditch which empties into an existing drainage ditch. All unpaved areas will have established vegetative cover to prevent the erosion of underlying soil material. During construction activities, silt fence will be installed along all fill slopes until vegetative cover has been established. Drawing sheet C-2 presents proposed erosion and sedimentation control measures. Since the transfer station construction will not disturb any stabilized or re-claimed areas, Henderson County will apply for an amendment to the current erosion and sedimentation control permit to cover construction and operation of the transfer station. CDM Camp Dresser & McKee 4-1 bp0696 Section 5 Drainage Control and Water Protection Requirements In accordance with Rule .0505(7)(b)(c), the Henderson County Transfer Station will be operated so as to prevent ponded water from coming in contact with discharged waste, and to contain and properly discharge collected leachate. The tipping floor of the transfer station is sloped away from the push pit area and towards the 3" trench drains located along the northern edge of the upper level concrete floor slab. The floor drains will collect any leachate (wash water) generated from washing the tipping floor during and after daily operations. The 3" trench drains connect to a 4" sanitary sewer line which travels along the upper level toward the southeast corner of the building. At the southeast corner of the building, the sewer line travels to the lower level. The transfer station lower level contains the drive-thru area for transfer trailer vehicles. The drive-thru area will have 3" driveway drains along the entire length to collect wash water. The driveway drains connect to a 4" sewer line that merges into the 4" sewer line from the upper level. Henderson County and CDM are currently evaluating the use of paved collection channels (on the upper and lower levels) instead of trench and driveway drains for the collection of leachate. The final system (drains or channels) will effectively collect and treat leachate separately from stormwater. The combined (upper and lower) flows will travel via a 4" sewer line to a pump station located outside the building (see sheet C-2). The collected leachate will be pumped to an existing onsite Pump Station which conveys wastewater to the City of Hendersonville Wastewater Treatment Plant. The tipping floor and drive-thru areas will be emptied and washed down at the end of each operating day. The upper level trench drains and lower level driveway drains (or paved channels) shall properly collect any leachate generated; and, minimize areas of ponded water within the transfer station.

HENDERSON COUNTY OFFICE OF THE COUNTY ENGINEER October 14, 1997 Mr. Jim Coffey N.C. Department of Environment, Health, and Natural Resources Division of Waste Management P.O. Box 27687 Raleigh, North Carolina 27611-7687 Ref Status of Solid Waste Transfer Station Construction Henderson County Landfill Permit# 45-04T Dear Mr. Coffey: Gary T. Tweed, P.E. County Engineer ZD On July 29, 1997 your Division issued above permit for the construction of the Solid Waste Transfer Station at the Henderson County Stoney Mountain Road Landfill. This letter is being provided to bring your Division up to date as to the status of the construction and to seek extension of the December 31, 1997 closure date for the landfill. Henderson County placed the project out to bids originally with a June 12, 1997 bid opening. This bid opening did not result in three acceptable bids and the project had to be rebid. The second bid was set for June 25, 1997 in which three bids were received. The two low bidders had failed to provide the acceptable bid documents and the third bidder was extremely higher than budget for the project. The Board of Commissioners rejected the bids and requested ihat the project be rebid. inuring this time the project scope was modified and the Couniy siari took responsibility for some of the preliminary grading work. The project was started by County staff. The third bid opening was set for July 23, 1997 at which time only two bids were submitted requiring a fourth bid opening on July 31, 1997. An acceptable bid was received, awarded by the Board of Commissioners on August 4, 1997 and contracts executed August 15, 1997 with an August 25, 1997 start of construction. The contracts called for completion of the project within 150 days (5 months) putting completion in mid January, 1998. The project has progressed well and the preliminary grading, storm drainage, and footings for the building have been installed. We have been providing assistance to the contractor in hopes of speeding up the construction and attempt to be operational by December 31, 1997. However, due to poor soil conditions much of the site has had to be under cut which has resulted in change orders'extending the contract time by approximately two weeks. At the 802 Stoney Mountain Road • Hendersonville, North Carolina 28791 • (704) 698-51 15 • FAX: (704) 697-5599 current time the contract for completion of construction runs to the end of January, 1998. I am anticipating additional time delays as we approach winter months due to weather. Should bad weather result in additional change order requests the project may not be complete and operational before the end of February, 1998. We are proceeding as quickly as possible to complete the project by the end of December, 1997 and stop the active landfill. However, based on the current status of the transfer station construction we do not expect to be able to meet the December 31, 1997 closure. Our options are, to keep the active landfill open, or to operate a temporary transfer area in the open. Since we will be in winter months we think that an open area transfer area will be difficult to operate and that continuing the active landfill would be the most environmentally sound option. We are requesting permission to continue the active landfill operation until completion of the transfer station which we feel will be operational on or before February 28, 1998. With respect to the hauling and disposal contracts, the County staff has received bids for these services and will be recommending to the Board of Commissioners by late October on a hauling and disposal contract. This contract should be in place by end of November 1997. The County is in the process of buying/leasing equipment for the transfer station operation and will be ready for the operation of the transfer station upon its completion. Your quick response to our request to continue the active landfill is needed in order to plan our operation during the end of 1997 and early 1998. Should you have any questions or need additional information, please contact my office at 704-698-5115. Your assistance in this matter is greatly appreciated. Sincerely, 00 G T. Tweed, P.E.
