The plan must include a set of drawings and a report which present the long-term, general design concepts related to construction, operation, and closure of the C&DLF unit(s). The scope of the plan must span the active life of the unit(s). Additional solid waste management activities located at the C&DLF facility must be identified in the plan and must meet the requirements of this Subchapter. The facility plan must define the waste stream proposed for management at the C&DLF facility. If different types of landfill units or non-disposal activities are included in the facility design, the plan must describe general waste acceptance procedures. 1.2 Definitions 15A NCAC 13B.0537(c) The terminology used in describing areas of the C&DLF unit(s) shall be defined as follows and must be used consistently throughout a permit application. As recommended by the North Carolina Department of Environment and Natural Resources (NCDENR), the following terms are defined as follows: Phase: An area constructed with a base liner system that provides no more than approximately 5 -10 years of operating capacity Cell: A subdivision of a phase, which describes modular or partial construction Sub-cell: A subdivision of a cell, which describes leachate and stormwater management for active or inactive areas of the constructed Construction and Demolition (C&D) Landfill (LF) 1.3 Facility Drawings 15A NCAC 13B .0537(d) The Facility Plan (Plan) includes a Site Plan depicting the development of the facility, physical site features, the C&D landfill units, closed municipal solid waste landfill, and staging areas for non-waste management units. The boundary survey was prepared by James L. Wright., November 1984. The topographic mapping outside the C&DLF footprint was provided by photogrammetric methods by Cartographic Aerial Mapping, Inc. for Brady Surveying Company dated June 13, 2008 and Landair Surveying, Inc. dated March 24, 2000. July 2015 2 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\facility plan_july_rev.docx 1.4 Facility Report 15A NCAC 13B .0537(e) This Facility Report includes a discussion of facility information related to the proposed waste stream, landfill capacity, and special engineering features. 1.4.1 Waste Stream Moore County, North Carolina (County) owns and operates the Moore County Landfill (Landfill), located on State Highway 5 in southwestern Moore County, to manage C&D waste, yard waste, white goods, electronics waste, scrap tires, and emergency storm debris generated within the county. The landfill has been constructed in four phases totaling 21.7 acres. 1.4.1.1 Types of Waste The landfill will accept C&D waste as defined by NCDENR. This includes waste generated solely from the construction, remodeling, repair, or demolition of pavement, buildings, or structures. C&D waste does not include municipal or industrial wastes that might be generated by the ongoing operations at buildings or structures. Unacceptable waste is defined in the Operations Plan. 1.4.1.2 Disposal Rates The anticipated average daily intake and disposal rate is estimated at 89 tons per day. This rate equates to an average monthly disposal rate of 1,935 tons per month assuming 260 operational days per year. 1.4.1.3 Service Area It is anticipated that the Moore County Landfill facility will receive C&D waste only from Moore County. 1.4.1.4 Waste Segregation The landfill only accepts permitted C&D waste and any materials that may pose health hazards, cause fires, or negatively impact the environment are considered unacceptable. Signs are posted at the facility stating the permitted types of waste and the location of the appropriate disposal area. Waste screening is accomplished through random inspections at the scale house and the tipping area. Employees are trained to detect and handle hazardous waste. Hazardous waste detected at the scale house is not permitted into the landfill and hazardous waste detected at the tipping area is isolated by installing a berm around the area. The Solid Waste Manager will notify NCDENR-Division of Waste Management (DWM) within 24 hours of a hazardous waste incident. The hauler will be responsible for removing hazardous waste from the property and if the hauler is not identified, the landfill will remove and dispose the waste appropriately. July 2015 3 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\facility plan_july_rev.docx 1.4.1.5 Equipment Requirements Specific equipment requirements will vary depending on landfill operations and additional equipment may be used as necessary. Equipment will be maintained and serviced according to the manufacturer's recommendation and operating and service manuals will be kept at the facility and followed. Generally, landfill equipment use will be associated with the following tasks:  Cell construction/preparation  Spreading and compacting waste  Spreading cover soil  Site maintenance and clean-up  Extinguishing fires along with other measures As the volume of the waste stream and material handling change (e.g., at start-up, during peak daily handling times, or during peak days), the number and type of machinery needed to perform daily operations will change. As of June 2015 the landfill maintained the following equipment onsite:  444-J John Deere Rubber Tire Loader  953-B Caterpillar Track Loader  613 Caterpillar Scraper Pan  370-A Rex Compactor  670-C John Deere Motor Grader  555-D Ford Backhoe  5400 John Deere Tractor The equipment used on site may be modified as necessary to facilitate efficient and compliant operations. The following is a sample list of equipment that may be used at the facility to perform necessary operational functions. 1.4.2 Landfill Capacity and Soil Resources The life expectancy of the landfill is based on the available airspace, anticipated disposal rate, and calculated specific gravity of waste. The available airspace is determined by comparing the topography of the site to the design intermediate cover grades. The disposal area is approximately 21.7 acres, and the top intermediate cover grades are approximately 455 feet above mean sea level. The final side slopes will be 3H:1V to an elevation of 440 feet, and will transition to an 8% slope up to 455 ft. During the next permit cycle, stability calculations will be performed and drawings revised to accommodate the permitted capacity of final side slopes at 3H:1V to an elevation of 470 feet, transitioning to an 8% slope up to 475 feet. July 2015 4 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\facility plan_july_rev.docx The total net capacity for Phases I-V is approximately 1,870,000 cubic yards, using the design intermediate cover grades. Of the total net capacity, it is estimated that approximately 412,000 cubic yards of storage is remaining. The disposal of C&D materials for the previous 30 months of operations (from November 01, 2012 to April 30, 2015) was determined to be 58,070 tons as shown in the Moore County Material Analysis Report from the Moore County Landfill scale house. This equates to a disposal rate of 23,228 tons per year. The specific gravity of waste was previously determined by analyzing the total weight and volume of disposed waste for a given timeframe. A specific gravity of 844 pound per cubic yard (lb/CY) was calculated based on the January 2005 topographic surveys and increased to 938 lb/CY based on the June 2008 topographic surveys. A specific gravity of 938 lb/CY will be assumed for the calculations of the remaining operating life of the landfill. Based on the available airspace, disposal rate, and calculated specific gravity of waste, the landfill is expected to remain operational until March 2024. The table below outlines the net capacity of the landfill. Table 1: Phase Volumes PHASE VOLUMES Phase Acres Waste Capacity (million cy) Net Per Phase Cumulative Net Cumulative Gross I & II 12.38 0.61 0.61 0.67 III 4.64 0.44 1.05 1.13 IV 4.68 0.40 1.45 1.55 V -- 0.31 1.76 1.87 Total 21.7 1.76 1.87  Phase V is a vertical expansion over previous phases. Stability calculations will be performed prior to modifying fill sequence to permitted top elevations.  Gross waste capacity includes waste, periodic cover, and intermediate cover. Soil for operations such as daily and intermediate cover, are utilized from the excavation of the Cell 5 area. The cap system will consist of an 18-inch-thick soil layer with a permeability of 1x10-5 cm/s or less, and an 18-inch-thick vegetative support layer capable of sustaining native plants. Construction appurtenances, such as roads and berms, will generally be constructed from onsite soil. July 2015 5 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\facility plan_july_rev.docx The following table summarizes the estimated soil requirements. A potential onsite borrow area is identified on Drawing G-01 which may yield 250,000 CY of soil for either landfill construction or operations. Additional evaluation of the borrow area will be needed to better determine the quantity and appropriate uses for the borrow material. Table 2: Soil Requirements SOIL REQUIREMENTS Material Minimum Quantity CY) Anticipated source Operations 30,000 On-site Miscellaneous Structural Fill 12,000 On-site 18” Soil Cap 56,000 On-site or off-site 18” Vegetative Support Layer 56,000 On-site or off-site Total Needs 154,000 Borrow Area(s) 250,000 On-site  The soil required for operations assumes a 10:1 waste-to-cover ratio (300,000 CY waste to 30,000 CY of cover).  The soil required for miscellaneous structural fill assumes 25:1 waste-to-soil ratio.  The soil cap and vegetative support layer assume a 0.1-foot overbuild.  The on-site borrow area soils may not be acceptable for all uses. 1.4.3 Special Engineering Features 1.4.3.1 Leachate Management No leachate management system is currently being utilized at the Moore County Landfill as it is not required by regulation. 1.4.3.2 Landfill Gas Management To protect public health and safety in the vicinity of the landfill, landfill gas produced by the decomposition of C&D waste will be controlled and monitored during the operational, closure, and post- closure periods. A gas monitoring program will be implemented for the purpose of maintaining the concentration of methane gas below the following regulatory levels, if necessary:  The concentration of methane gas generated is not to exceed 25 percent of the lower explosive limit (LEL) for methane in on-site structures. July 2015 6 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\facility plan_july_rev.docx  The concentration of methane gas is not to exceed the LEL for methane at the facility property boundary. Landfill gas is a by-product from the decomposition of organic waste in a C&D Landfill. The major components of landfill gas are methane and carbon dioxide. Other gases, such as volatile organic compounds, may be present in trace quantities. Gas monitoring will be performed during the active life of the landfill and throughout the closure and post- closure periods. At a minimum, quarterly monitoring of explosive gases will be conducted at all gas detection probes and in structures at the landfill. As required by NCDENR guidance, methane and hydrogen sulfide will be monitored. If additional structures are built, the monitoring program will be expanded to include the new structures. Gas detection probes will be installed around the boundary of the waste disposal unit. Probes should not be needed where site topography permits gas to be released to the atmosphere before it migrates to the property boundaries, or where the site is bound by surface water features. The facility’s Operation Plan contains more detailed information regarding landfill gas management. 1.4.3.3 Containment and Environmental Controls Protective Final Cover System A protective final cover system will be implemented at the completion of landfill operations in order to limit infiltration of precipitation into the waste mass and minimize creation of leachate and landfill gas. A properly engineered final cover system, which is properly maintained, will significantly limit precipitation from entering the waste mass, and thus minimize the formation of leachate and prevent the emission of landfill gas, which is a known greenhouse gas. The goal of a final cover system is to minimize long-term maintenance and to protect human health and the environment from both leachate and greenhouse gases. The cap system will consist of a soil liner layer of at least 18 inches with permeability no greater (slower) than 1.0 x 10-5 cm/sec and a vegetative support layer of at least 18 inches capable of sustaining native plant growth. Within 6 months of the anticipated date of final receipt of waste, Moore County will select the material(s) to be used for the layer of restricted permeability. Three choices currently anticipated are:  18 inches of on-site 10-5 cm/sec soils  18 inches of off-site 10-5 cm/sec soil  Geosynthetic liner (e.g. GCL, LLDPE) typically slower than 5 x 10-9 cm/sec. At that time, the existing soils available for capping the waste will be evaluated for compliance with the cap system requirements. If soils of sufficient quantity and quality exist, a plan to incorporate those soils into the cap system may be proposed for approval by NCDENR. The County may evaluate the economic July 2015 7 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\facility plan_july_rev.docx cost of a soil cap and a geosynthetic cap. If a geosynthetic cap is cost effective, then it may be proposed for approval by NCDENR. This proposal would include a revised Engineering Plan including slope stability analysis (global and veneer slope analyses and stormwater drainage and erosion control design), technical specifications of the selected geosynthetic material which must satisfy the performance standards and minimum criteria based on the design of the selected final cap, a revised Construction Quality Assurance Plan, and a revised Closure Plan with closure cost estimates. Construction methods shall be based upon the type and quality of the borrow source and shall be verified in the field by constructing a test pad. A professional engineer shall certify that the installation of the permeability restricted layer conforms to the plans approved by the NCDENR-DWM. The vegetative support layer will consist of no less than 18 inches of earthen material capable of sustaining native plant growth. It is anticipated that this layer will consist of suitable on-site or off-site borrow material. The materials of this layer will be selected considering soil type, pH, erodibility, side slope drainage, and other factors. The vegetation will be selected based upon the following characteristics:  Species of grasses which are locally adapted and resistant to drought or temperature extremes.  Having roots which will not disrupt the low permeability layer.  Ability to thrive in low nutrient soil and develop a good stand to resist erosion.  Ability to survive and function with little or no maintenance. All cover material will be free of putrescible material, solid waste, construction debris, and other deleterious materials. 1.4.3.4 Other Solid Waste Management Areas A drop-off/recycling area is also available for the general public and is located at the entrance to the facility. The drop-off/recycling area accepts aluminum cans, steel cans, glass, newspapers, magazines, mixed paper, scrap metal, white goods, electronics waste, scrap tires, and yard waste. These materials are sent their final disposal destination as described in the Operations Plan and are not disposed of in the landfill. Staging Areas for emergency storm debris, yard waste, white goods, electronics waste, scrap tires, and the citizen drop off area are shown on the Overall Site Plan. 1.4.3.5 Special Engineering Features There are no special engineering features proposed for the facility at this time.

This plan was prepared in general accordance with Rule .0542 and provides details of the procedures and policies, which shall be implemented throughout the life of the proposed landfill expansion. 1.1 Operation Drawings Drawing P-02 depicts the anticipated fill progression and yearly contour transitions. As waste is placed, storm water management features such as drainage benches, side slope swales, and slope drains will be installed. 1.2 Waste Acceptance and Disposal All vehicles must stop at the scale house located at the entrance of the existing landfill facility and visitors are required to sign-in. All refuse transportation vehicles are weighed and the content of the load assessed. The scale attendant(s) requests from the driver of the vehicle entering the landfill a description of the waste it is carrying to confirm that unacceptable waste is not allowed into the landfill. The attendant(s) then visually checks the vehicle as it crosses the scale. The landfill will accept only those solid wastes it is permitted to receive. The County will notify the North Carolina Department of Environment and Natural Resources (NCDENR) – Division of Waste Management (DWM) within 24 hours of attempted disposal of any waste the landfill is not permitted to receive, including waste from outside the area the landfill is permitted to serve. Asbestos waste will be managed in accordance with 40 CFR 61. The regulated asbestos waste must be covered immediately with soil in a manner that will not cause airborne conditions and must be disposed of separate and apart from other solid wastes: 1. In a defined isolated area within the footprint of the landfill, or 2. In an area not contiguous with other disposal areas. Separate areas must be designated so that asbestos is not exposed by future land-disturbing activities. Wastewater treatment sludge must not be accepted for disposal. Wastewater treatment sludge may be accepted, with the approval of the NCDENR-DWM, for utilization as a soil conditioner and incorporated into, or applied onto, the vegetative growth layer. The wastewater treatment sludge may not be applied at greater than agronomic rates or to a depth greater than six inches. July 2015 2 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx 1.3 Waste Exclusions The following wastes will not be disposed of at the C&D landfill unit. 1. Containers such as tubes, drums, barrels, tanks, cans, and bottles unless they are empty and perforated to ensure that no liquid, hazardous or municipal solid waste is contained therein. 2. Garbage as defined in G.S. 130A-290(a)(7). 3. Hazardous waste as defined in G.S. 130A-290(a)(8), to also include hazardous waste from conditionally exempt small quantity generators. 4. Industrial solid waste unless a demonstration has been made and approved by the NCDENR- DWM that the landfill meets the requirements of Rule .0503(2)(d)(ii)(A). 5. Liquid wastes. 6. Medical waste as defined in G.S. 130A-290(a)(18). 7. Municipal solid waste as defined in G.S. 130A-290(a)(18a). 8. Polychlorinated biphenyls (PCB) wastes as defined in 40 CFR 761. 9. Radioactive waste as defined in G.S. 104E-5(14). 10. Septage as defined in G.S. 130A-290(a)(32). 11. Sludge as defined in G.S. 130A-290(a)(34). 12. Special wastes as defined in G.S. 130A-290(a)(40). 13. White goods as defined in G.S. 130A-290(a)(44). 14. Yard trash as defined in G.S. 130A-290(a)(45). The following wastes will not be received if separate from C&D waste. 1. Lamps or bulbs including but not limited to halogen, incandescent, neon or fluorescent. 2. Lighting ballast or fixtures; thermostats and light switches. 3. Batteries including but not limited to those from exit and emergency lights and smoke detectors. 4. Lead pipes. 5. Lead roof flashing. 6. Transformers. 7. Capacitors. 8. Copper chrome arsenate (CCA). 9. Creosote treated woods. Waste accepted for disposal in a C&D landfill unit must be readily identifiable as C&D waste and must not have been shredded, pulverized, or processed to such an extent that the composition of the July 2015 3 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx original waste cannot be readily ascertained. However, C&D waste that has been shredded, pulverized or otherwise processed may be accepted for disposal from a facility that has received a permit from an authorized regulatory authority which specifies such activities are inspected by the authority and whose primary purpose is recycling and reuse of the C&D material. A waste screening plan and waste acceptance plan must be made available to the NCDENR-DWM upon request. A container will be located near the working face to collect and remove banned and/or recyclable items. Moore County, or its employees, will not knowingly dispose any type or form of C&D waste that is generated within the boundaries of a unit of local government that by ordinance: 1. Prohibits generators or collectors of C&D waste from disposing that type or form of C&D waste, or 2. Requires generators or collectors of C&D waste to recycle that type or form of C&D waste. 1.4 Waste Inspection In order to assure that prohibited wastes are not entering the landfill facility, screening programs will be implemented. Waste shall be screened at both the scale house entrance and at the working face by trained personnel. Screening programs for visual and olfactory characteristics of prohibited wastes will be an ongoing part of the landfill operation. Approximately one percent of all waste trucks bound for the C&D landfill will be selected for a more thorough screening. Selected vehicles will be directed to an area of intermediate cover adjacent to the working face where the vehicle will be unloaded. The waste will be inspected for municipal solid waste (MSW), liquid waste, hazardous waste, PCB waste, and other banned items. Waste is carefully spread using suitable equipment. An attendant trained to identify wastes that are unacceptable inspects the waste discharged at the screening site. If unacceptable waste is found, the load will be isolated and secured by constructing a berm around the area. For regulated hazardous or PCB wastes, the Solid Waste Division Manager will notify officials of the NC DENR, Division of Waste Management. The hauler is responsible for removing unacceptable waste from the landfill property. If no unacceptable waste is found, the load will be pushed to the working face and incorporated with the daily waste. For each vehicle screened, a random waste screening inspection form will be filled out and will be kept on-site. An inspection form should include the following information:  The date and times wastes were received for inspection  Source and type of wastes  Vehicle and driver identification  All observations made by the inspector July 2015 4 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx  Final disposition of waste after inspection Records of information gathered as part of the waste screening programs will be maintained at the landfill during the active life of the C&D unit and as long as required by the County and the Division. 1.5 Cover Material Requirements Cover soil will be placed on solid waste with six inches of earthen material when the waste disposal area exceeds one-half acre and at least once weekly. Cover will be placed at more frequent intervals if necessary to control disease vectors, fires, odors, blowing litter, and scavenging. A notation of the date and time of the cover placement will be recorded in the operating record. Areas which will not have additional wastes placed on them for three months or more, but where final termination of disposal operations has not occurred, will have at least 6 inches of cover soil and be stabilized with vegetative ground cover or other stabilizing material. The County may request use of alternative materials or an alternative thickness of cover from the NCDENR-DWM by demonstrating that the alternative material or thickness controls disease vectors, fires, odors, blowing litter, and scavenging without presenting a threat to human health and the environment. 1.6 Spreading and Compacting Requirements Incoming waste at the landfill will be confined to the smallest working face feasible. Appropriate control devices such as berms, fences, and cover material will be used as needed to prevent windblown debris. At the conclusion of each operating day, all windblown material resulting from the operation will be collected and disposed of by the staff. 1.7 Disease Vector Control The County will prevent or control on-site populations of disease vectors using techniques appropriate for the protection of human health and the environment. For purposes of this item, "disease vectors" mean any rodents, flies, mosquitoes, or other animals or insects, capable of transmitting disease to humans. Vectors are generally attracted by opportunities for food and shelter. C&D waste is not a food source for many vectors. Vectors seeking shelter in the waste mass can be discouraged by covering of the waste and proper grading to prevent ponding of water. If vectors become a problem, a licensed exterminator or other legal means of control shall be implemented.

Historical monitoring results submitted to NCDENR- DWM indicate the presence of methane above the lower explosive limit (LEL) at locations associated with the MSW unit (i.e., GP-10, MW-6, and MW-15). However, data from recent monitoring events show the presence of methane above the LEL at GP-15, which is close to the C&D unit and in the yard waste management area. The source of the methane is likely the yard waste area rather than the C&D unit. The County has completed corrective measures including:  2005: a trenching and venting network consisting of a trench and 12 passive LFG vents was installed  2007: trenching and venting network was expanded via 12 additional LFG 7.  2014: three in-waste passive gas vents (GV-30, GV-31, and GV-32) were installed in February 2014 as part of the Contingency Plan Update and Implementation Plan-Revised approved by NCDENR on June 5, 2013 related to the Assessment of Corrective Measures for to address volatile organic constituents in groundwater samples from monitoring wells at the MSW facility. Additional corrective measures for methane may be required in the future as part of methane and groundwater compliance activities. The following sections discuss the proposed locations of landfill gas monitoring wells, the monitoring of structures, and the monitoring frequency. 1.8.1.1 Landfill Gas Monitoring Well Locations Nine landfill gas monitoring wells (GP-9 through GP-17), the headspace of two monitoring wells (MW-6 and MW-15), and three structures (maintenance building, transfer station, and scalehouse) are monitored quarterly for methane and hydrogen sulfide. The network monitors both the active C&D facility and the adjacent closed MSW unit. The locations on these landfill gas monitoring wells are shown on Drawing G-01. 1.8.1.2 Structure and Ambient Sampling As stated above, three structures (maintenance building, transfer station, and scalehouse) are monitored quarterly as part of the landfill gas monitoring network. 1.8.1.3 Landfill Gas Monitoring Frequency Landfill gas monitoring will be performed on a quarterly basis as required in Title 15A NCAC 13B.0544(d)(2)(B) and in accordance with NCDENR November 2010 Landfill Gas Monitoring Guidance. In the event that the explosive action level or compliance level is exceeded, the monitoring frequency will increase to monthly until three consecutive months have passed without a methane action level or compliance level exceedance, at which time the monitoring frequency will revert to quarterly. July 2015 6 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx 1.8.1.4 Landfill Gas Sampling Procedures The following sections outline the recommended procedures for performing required landfill gas monitoring well and facility structure monitoring for methane gas. 1.8.1.5 Detection Equipment Used The GEM-2000 Plus is the preferred monitoring device for monitoring landfill gas monitoring wells. Alternatively, a digital or analog manometer combined with a vacuum-pump-equipped monitoring device designed to measure methane gas and hydrogen sulfide concentrations can be used. In addition to the monitoring device(s), the following equipment and documents should be readily available during monitoring events:  Copy of the facility’s Landfill Gas Monitoring Plan  A copy of the Operation Manual(s) for the equipment being used during monitoring  Blank copies of the Landfill Gas Monitoring Log  Calibration gas (if applicable)  Barometer (if available)  Personal protection equipment (site specific)  Necessary keys (site specific) Gas monitoring equipment should be calibrated daily, prior to use in the field. Generally, one calibration per day is sufficient. In some instances where highly variable concentrations are being observed, it may be necessary to re-calibrate the monitoring device during the work day to ensure that instrument drift is minimal. Instrument drift can be checked with a calibration gas of known concentration. If more than a 3% difference is observed between the instrument reading and the gas standard during an instrument drift check, the unit should be recalibrated. Field calibration should be performed in accordance with the instrument manufacturer’s recommendations using an approved gas standard. Generally, when landfill gas monitoring wells are monitored it is best to calibrate the unit with standard composed of 15% or less methane. Calibration activities should be documented on a calibration log. Gas monitoring equipment should also be calibrated by the manufacturer or supplier in accordance with the recommended schedule for that instrument. 1.8.1.6 Sampling Procedures After calibrating the monitoring instrument, record the weather conditions at the site, including the barometric pressure and ambient temperature. The temperature and barometric pressure should be logged at the beginning and ending of each field day. Site-specific barometric pressure readings are July 2015 7 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx preferred. In the event that a barometer is not available, barometric pressure readings from a nearby weather station can be used. Monitoring should be conducted between noon and sunset. 1.8.1.7 Landfill Gas Monitoring Well Gas Concentration Measurements Before connecting the monitoring instrument to the landfill gas monitoring well, purge the connector tube for at least one minute prior to taking reading. Connect the instrument tubing to the landfill gas monitoring well cap fitted with a stopcock valve or quick connect coupling. Open the valve and record the initial reading and then the stabilized reading for methane and hydrogen sulfide. A stable reading is one that does not vary more than 0.5 percent by volume on the instrument’s scale. Turn the stopcock valve to the off position and disconnect the tubing. Proceed to the next landfill gas monitoring well and repeat. 1.8.1.8 Facility Structure Gas Concentration Measurements Confined spaces, which require a confined space permit to enter, are excluded from these general monitoring requirements. The following monitoring plan applies to the structures at the facility:  After entering the designated structure, turn on the gas monitoring device and vacuum pump and traverse the accessible and open area on the first floor of the facility structure while holding the intake hose for the monitoring device at shoulder height. During the traverse, observe the meter for any measurable methane concentrations and record the time and concentration on the monitoring log.  If measurable methane concentrations are observed in a facility structure, attempts to identify the source of the methane should be made. If the facility structure is elevated and has a crawl space, the crawl space beneath the facility should be monitored from outside of the structure on accessible sides to determine if the methane gas is migrating into the structure from the crawl space. Do not enter a crawl space beneath a structure without proper authorization and sufficient personal protection equipment, including an oxygen monitoring device, since these areas may be considered confined spaces. If the facility structure is constructed on grade, ambient air near the exterior walls at floor level or near cracks in the floor, if exposed, should be monitored to determine if gas is migrating upward along or through the foundation. 1.8.1.9 Well Decommissioning Procedures If a landfill gas monitoring well requires decommissioning, an abandonment record shall be submitted to NCDENR within 30 (thirty) days of the decommissioning. The landfill gas monitoring well(s) shall be decommissioned in accordance with 15A NCAC 2C .0113(d) by a certified well driller. The landfill gas monitoring well(s) shall be over-drilled and sealed with grout via tremie-pipe if located in the future waste footprint. The landfill gas monitoring well(s) shall be sealed with grout and all surface completions removed if not located in the future waste footprint. The decommissioning report will be sealed by a North Carolina Licensed/Professional Geologist. July 2015 8 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx 1.8.1.10 Record Keeping and Reporting Quarterly gas monitoring results shall be maintained by the facility operator for the life of the facility operation, closure, and post-closure care periods. Each quarterly report shall be retained on-site as part of the permanent operating record for the facility. 1.8.1.11 Landfill Gas Monitoring Form The date, time, location, sampling personnel, equipment, atmospheric temperature, reported barometric pressure, general weather conditions at the time of sampling, and the concentration of methane and hydrogen sulfide shall be recorded on the Landfill Gas Monitoring Field Log (see Appendix 1). 1.8.1.12 Sampling Reports A letter report that includes the Landfill Gas Monitoring Form, calibration certificate for the field meter, and a map showing the monitoring locations will be prepared after each monitoring event. Monitoring records will be kept on site in the facility files. In the event that explosive gas concentrations are detected in excess of allowable limits in the compliance monitoring points, a report will also be provided to the NCDENR within 5 days of the exceedance as described below. 1.8.1.13 Permanent Record Keeping A copy of each quarterly report shall be retained on-site as part of the permanent operating record for the facility. 1.8.1.14 Contingency Plan Pursuant to the 15A NCAC 13B, the compliance levels for landfill gas monitoring are 25% of the lower explosive limit (LEL) for methane and other explosive gasses (1.25% methane by volume) in facility structures (excluding gas control or recovery system components) and 100% of the LEL (5% methane by volume) for methane at the facility boundary. If either of these compliance levels is exceeded, the operator shall:  Take all immediate steps necessary to protect public health and safety, including those required by the contingency plan. The contingency plan for this facility is as follows:  Evacuating all personnel from any facility structure(s) exceeding the safe LEL levels  Notifying local fire officials of the exceedance if there are habitable structures within 1,000 feet of the property boundary  Isolating the effective area and post signs around the affected area indicating the potential health and safety risk  Posting signs in the affected area indicating a “No Smoking” area  Appropriate safety training for all personnel entering in the isolated area July 2015 9 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx  Notify NCDENR in a written statement within five working days of learning that action levels have been exceeded, and indicate what has been done or is planned to be done to resolve the problem.  Begin initial remediation actions, which may include the following activities:  Additional temporary gas monitoring probe installations and sampling to determine the extent of the gas migration  Increased monitoring of probes, structures, and any identified preferred flow pathways to verify concentrations and to protect human health  Within 60 days of detection, implement a remediation plan for the explosive gas releases and submit it to NCDENR for amendment of the facility permit The Landfill Gas Remediation Plan shall describe the nature and extent of the problem and the proposed remedy. The plan shall include an implementation schedule specifying timeframes for implementing the corrective actions, an evaluation of the effectiveness of such corrective actions, and milestones for proceeding in implementation of additional corrective actions, if necessary to re-establish compliance. Gas control systems proposed in a Landfill Gas Remediation Plan shall be designed to:  Prevent methane accumulation in on-site structures  Prevent methane compliance level exceedances at the facility boundary  Provide for the collection, treatment, and destruction/disposal of decomposition gases and condensate  Comply with Clean Air Act requirements, as applicable 1.8.2 Fire Control 1.8.2.1 General The following protocols will be utilized for fire control at the facility:  Smoking will be confined to designated areas only, away from active areas of the Landfill, fueling stations, methane vents, and other fire sensitive areas.  The County will ensure that the disposal area does not violate any applicable requirements developed under a State Implementation Plan (SIP) approved or promulgated by the U.S. EPA Administrator pursuant to Section 110 of the Clean Air Act, as amended.  Open burning of solid waste, except for the approved burning of land clearing debris generated on-site or debris from emergency clean-up operations is prohibited. Prior to any burning, a request must be sent to the NCDENR-DWM for review and approval. In addition, the Division of Air Quality and local fire department must approve the activity prior to burning. A notation of the date of approval and the name of the NCDENR-DWM personnel who approved the burning must be included in the operating record. Fires that develop spontaneously at the C&D unit working face will be extinguished by covering the burning area with soil. An ample supply of soil will be stored near the working face during operational hours. July 2015 10 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx  Equipment must be provided to control accidental fires and arrangements must be made with the local fire protection agency to immediately provide fire-fighting services when needed. 1.8.2.2 Fire on Landfill Working Face The following actions should be taken if a fire develops at the working face. 1. Notify the supervisor of the existence of the fire. 2. If the supervisor determines the fire is controllable, follow his instructions. Compactors should be used to cut and push burning garbage away from working face and then cover with soil until fire is extinguished. 3. If the supervisor determines the fire to be uncontrollable, evacuate the area immediately using predetermined evacuation paths. 4. Concurrently, the supervisor notifies the scale attendant via two-way radio or cell phone that a fire has developed on the C&D unit and status of the fire. If it is determined that the fire is uncontrollable, advise the scale attendant to call 911 for fire and rescue. If the fire is deemed to be controllable, inform the scale attendant of steps taken to control the fire and also when the fire is extinguished. The scale attendant will not allow additional waste disposal vehicles to enter the landfill until the fire has been extinguished. The scale attendant will direct emergency vehicles to the location of the fire. 5. The supervisor and landfill employees will assist fire and rescue personnel as directed by the senior fire officer. 6. The supervisor will ensure that all landfill emergency equipment is prepared for reuse before resuming normal operations. 1.8.2.3 Fire in Landfill Equipment The main goal in controlling a fire involving landfill equipment is for the equipment operator to evacuate to safety. The following steps should be followed in case of a fire involving landfill equipment. 1. Evacuate the equipment immediately upon discovery of a fire. 2. Inform the supervisor of the exact location of the fire, the equipment involved, and whether any individuals remain in the equipment. 3. Follow the supervisor's instructions to control the fire and to allow rescue of injured individuals remaining in the equipment. 4. Concurrently, the supervisor notifies the scale attendant via two-way radio of the existence of the fire involving equipment and if any personnel are injured and/or remain in the equipment. The scale attendant will call 911 for fire and rescue if needed and will dispatch a vehicle to landfill entrance to escort emergency vehicles to the location of the fire. The scale attendant will not allow additional vehicles to enter the landfill until the fire is extinguished. July 2015 11 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx 5. If the supervisor deems the fire to be controllable and no injuries have occurred to personnel, the fire will be extinguished by appropriate measures (i.e., fire extinguisher). If the supervisor determines assistance from local fire and/or rescue squad will be required, efforts to control the fire to prevent spreading will be taken until the fire and rescue squad arrive. These measures include:  preliminary first aid on injured personnel  continuing to soak burning equipment with water from water truck  moving other equipment from vicinity of burning equipment  directing vehicles currently unloading waste away from the disposal area 1.8.2.4 Explosions Fires and explosions that occur at the landfill require verbal notice to the NCDENR-DWM within 24 hours and written notification within 15 days. Written notification must include the suspected cause of fire or explosion, the response taken to manage the incident, and the action(s) to be taken to prevent the future occurrence of fire or explosion. In the event of an explosion at the C&D unit, the following procedures should be followed: 1. Evacuate to a safe area. 2. Assist in rescue of injured personnel. 3. The supervisor will notify the scale attendant of the occurrence of the explosion and the results of such explosion (fire, injured personnel, and malfunctioning equipment). The scale attendant will dial 911 as instructed by the supervisor. The scale attendant will not allow additional waste vehicles to enter the facility. 4. Fires that occur as a result of the explosion will be controlled whenever possible. 5. The supervisor and landfill employees will assist fire and rescue personnel as directed by the senior fire officer. 6. The supervisor will ensure that all emergency equipment is prepared for reuse before resuming normal operations. 7. The supervisor will alert the scale attendant when the situation is under control and when normal operations can resume. 8. The supervisor will prepare a written report of the incident and submit it within three working days. 1.9 Access and Safety Requirements Entry to the site will be limited to landfill personnel, approved contractors, approved waste haulers, visitors, and other properly identified persons whose entry is authorized by the site management. The County reserves the right to restrict access to the site. Visitors may be allowed near the active area only when accompanied by a site representative July 2015 12 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx 1. The landfill will be adequately secured by means of gates, chains, berms, fences and other security measures approved by the NCDENR-DWM to prevent unauthorized entry. The landfill entrance is protected by a 6-foot chain link fence with triple strands of barbed wire to prevent unauthorized entry into the site. Areas currently not protected by fencing are inaccessible by motor vehicle due to steep slopes, berms, water barriers, trees, etc. The disposal areas will be surrounded on all sides by natural barriers, fencing, or an equivalent means of controlling vehicular access and preventing illegal disposal. Gates will limit access, and such gates will be securable and equipped with locks. 2. In accordance with G.S. 130A-309.25, an individual trained in landfill operations must be on duty at the site while the facility is open for public use and at all times during active waste management operations to ensure compliance with operational requirements. 3. The access road to the working face will be of all-weather construction and kept in good condition. A paved road within the perimeter of the property facilitates two-way traffic to the landfill units. 4. Dust will be controlled on the access roads applying water to the roads on an as needed basis. 5. An entrance sign will be posted stating the facility’s name, permit number, and operating hours. Additional signs will be posted for allowable speed limit, promote an orderly traffic pattern to and from the discharge area, and maintain efficient operating conditions. Proper signage will be placed in high visibility areas, informing facility users that no hazardous or liquid wastes can be received. 6. The removal of solid waste from the landfill is prohibited unless the operational plan includes a recycling program which has been approved by the NCDENR-DWM. The general public is prohibited from removal activities on the working face. 7. The access road to the site and access roads to monitoring locations will be of all- weather construction and maintained in good condition. 1.10 Erosion and Sedimentation Control Requirements Adequate sediment control measures consisting of vegetative cover, materials, structures or devices will be utilized to prevent sediment from leaving the landfill and preventing excessive on-site erosion of the landfill. An Erosion and Sediment Control Plan has been approved by the NC Division of Land Resources, Land Quality Section. Refer to the “Letter of Approval” for the Erosion and Sediment Control Plan from the NC Division of Land Resources, Land Quality Section dated November 25, 2009. July 2015 13 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx 1.11 Drainage Control and Water Protection Requirements The fill sequence of Phases I-IV is illustrated on Drawing P-02. As filling operations are initially proceeding, stormwater from the unfilled portion of Cell 5 is kept out of the fill area. Cell 5 has been designed with maximum waste side slopes of 3H:1V and maximum 8% top slopes to promote runoff and prevent ponding over or in the waste. Side slope terraces and perimeter drainage channels at the toe of the slope will provide runoff, erosion, and sediment control. The drainage channel will allow for the movement of surface water from landfilling activities and provide a settling zone for sediments carried from the site. The channel is constructed to allow drainage via sediment basins through natural outfalls and tributaries to Horse Creek. Sediment basins will also prevent the discharge of pollutants that violate requirements of the Clean Water Act, including, but not limited to, NPDES requirements, into the waters and wetlands of the United States. The County currently monitors the facility under general permit number NCG120000, Certificate of Coverage number NCG120084. As described in the approved Water Quality Monitoring Plan, the landfill has a comprehensive surface and groundwater monitoring program to provide early detection of any leachate migration problems. In the event any constituents are detected above the allowable limits, measures will be taken to begin assessing the extent of contamination. If necessary, corrective actions will be taken to prevent pollution of waters or wetlands. The following operational controls will be used. 1. Surface water shall be diverted from the operational area. 2. Surface water shall not be impounded over or in waste. 3. Solid waste shall not be disposed of in water. 1.12 Survey for Compliance Within 60 days of the County’s receipt of the NCDENR-DWM's written request, the County must conduct a survey of the active or closed portions of the landfill in order to determine whether operations are being conducted in accordance with the approved design and operational plans. The County must report the results of the survey, including a map produced by a North Carolina registered land surveyor survey, to the NCDENR-DWM within 90 days of receipt of the NCDENR- DWM's request. 1.13 Operating Record and Recordkeeping Requirements Records for facility inspections, tonnage, waste generators, and employee training will be kept at the facility and made available to the NCDENR-DWM upon request within a reasonable period of time. July 2015 14 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx Records for gas/groundwater monitoring results and corresponding analytical data, Closure/Post Closure cost estimates, and financial assurance documentation will be kept in the office of the Solid Waste Administrator. The information will be made available to the NCDENR-DWM upon request within a reasonable period of time. Copies of the Operation Plan will be kept at the facility and the office of the County Public Works Director. All information contained in the Operating Record will be furnished to the NCDENR-DWM according to the permit or upon request, or be made available for inspection by the NCDENR-DWM. The County will record and retain at the facility, or in an alternative location near the facility, the following information: 1. Records of random waste inspections, monitoring results, certifications of training, and training procedures required by Rule .0544. 2. Amounts by weight of solid waste received at the facility to include, consistent with G.S. 130A-309.09D, county of generation. 3.

Any closure or post-closure monitoring, testing, or analytical data as required by Rule .0543. 5. Any cost estimates and financial assurance documentation required by Rule .0546. 6. Notation of date and time of placement of cover material. 7. All audit records, compliance records and inspection reports. The Operating Record will also include the following. 1. A copy of the approved operation plan and the engineering plan required by Rule .0539. 2. A copy of the current Permit to Construct and Permit to Operate. 3. The Monitoring Plans. 1.14 Exceptional Operations In the event of a fire, explosion, spill, natural disaster, long-term power outage, major equipment breakdown or other atypical event that effects the normal operation of the landfill, the landfill manager, with the assistance of others, will develop and implement an event specific contingency plan. If the plan requires the redirection or suspension of service, the public and NCDENR will be notified as appropriate. The landfill manager will be responsible for providing the personnel and equipment necessary to handle exceptional operation events in a manner consistent with the requirements of the permit. July 2015 15 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx 1.15 Miscellaneous Waste Management 1.15.1 Moore County Landfill Collection Center A manned solid waste collection center is located near the entrance of the landfill. The collection center is approximately a half acre in size and accepts household waste, plastic, aluminum, newspaper, and magazines. The County provides containers labeled for each of the acceptable materials. Space is maintained between containers for facilitating inspection and firefighting. Users of the collection center do not cross the scales but must enter and exit thru a gate before the scale house. The operating hours are Monday through Saturday from 7:00 a.m. to 7:00 p.m. The site is closed on the following four holidays: New Year’s Day, Independence Day, Thanksgiving Day, and Christmas Day. When a container is full, it is removed from the collection center within 24 hours by Moore County staff. The following are the final disposal destinations for each accepted material. Household Waste On-site transfer station Permit # 63-02T Plastic, Aluminum, and Paper Products North Davidson Garbage and Recycling Center 4157 Old US Hwy 52 Lexington, NC 27295 1.15.2 Scrap Tires Scrap tires are currently collected free of charge at the landfill. It is estimated that 80 percent of the tires collected are passenger tires, 15 percent truck tires, and 5 percent large off-road tires. Two box trailers, approximately 50’ in length, are available for tire collection located in only one area of the Landfill (refer to Overall Site Plan, G-01). Users are responsible for unloading their scrap tires and stacking them directly into these trailers. When a trailer is full, it is removed from the landfill and an empty trailer is brought to the landfill. Approximately one trailer per week is collected and removed from the landfill. The final disposal destination of the tires is currently: Central Carolina Tire Disposal 1616 McKoy Town Rd. Cameron, NC 28326 1.15.3 White Goods/Scrap Metal White goods and scrap metal are collected and stored at the landfill on a gravel pad that is approximately 300’ by 300’ in only one area of the Landfill (see Overall Site Plan G-01). The County July 2015 16 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\response to comments\final\operations plan_july_rev.docx is currently under contract with Metal Recycling Services, Inc. to extract and collect the refrigerant from the white goods and remove the white goods and scrap metal from the landfill. The white goods and scrap metal are not allowed to exceed the available storage area. Extraction of refrigerant from the white goods takes place quarterly. White goods and scrap metal are removed from the site every six weeks or when 125 tons have been collected. More frequent collection may occur upon mutual agreement of the County and Recycling Services, Inc. 1.15.4 Electronics Waste Electronics waste collected and stored at the landfill on a covered concrete pad adjacent to the white goods staging area (see Overall Site Plan G-01). These materials are sent to a third party facility for proper disposal and recycling. The final destination of these materials is currently: Southern Environmental Solutions of the Carolinas, Inc. 895 State Rd 1403 Peachland, NC 28133 1.15.5 Yard Waste Two yard waste staging areas are provided at the facility and are located directly west and northwest of the active C&D landfill (see Overall Site Plan G-01). The facility will store and/or stockpile unprocessed vegetation and ground material in the designated areas and these materials will not be distributed to the public or composted by the County. The material will be transported to either a compost facility, a wood waste burner, or used on-site. Refer to the Moore County Landfill Yard Waste Treatment and Processing Facility Operations Plan, last revised January 2013, for more details. 1.15.6 Transfer Station An on-site transfer station was constructed in 1993 for handling of MSW upon the closure of the MSW landfill located at the facility. The structure is located south of the landfill (see Overall Site Plan G-01) and operates under Permit #63-02T. The transfer station is handled separately from this Permit Amendment and operations are currently contracted to Republic Services of NC, LLC. 1.15.7 Emergency Storm Debris Management Area An emergency storm debris management area is located north of the landfill (see Overall Site Plan G-01) and is provided by the facility to assist the County with managing debris associated with cleanup efforts conducted due to severe weather conditions.

The plan must include a set of drawings and a report which present the long-term, general design concepts related to construction, operation, and closure of the C&DLF unit(s). The scope of the plan must span the active life of the unit(s). Additional solid waste management activities located at the C&DLF facility must be identified in the plan and must meet the requirements of this Subchapter. The facility plan must define the waste stream proposed for management at the C&DLF facility. If different types of landfill units or non-disposal activities are included in the facility design, the plan must describe general waste acceptance procedures. 1.2 Definitions 15A NCAC 13B.0537(c) The terminology used in describing areas of the C&DLF unit(s) shall be defined as follows and must be used consistently throughout a permit application. As recommended by the North Carolina Department of Environment and Natural Resources (NCDENR), the following terms are defined as follows: Phase: An area constructed with a base liner system that provides no more than approximately 5 -10 years of operating capacity Cell: A subdivision of a phase, which describes modular or partial construction Sub-cell: A subdivision of a cell, which describes leachate and stormwater management for active or inactive areas of the constructed Construction and Demolition (C&D) Landfill (LF) 1.3 Facility Drawings 15A NCAC 13B .0537(d) The Facility Plan (Plan) includes a Site Plan depicting the development of the facility, physical site features, the C&D landfill units, closed municipal solid waste landfill, and staging areas for non-waste management units. The boundary survey was prepared by James L. Wright., November 1984. The topographic mapping outside the C&DLF footprint was provided by photogrammetric methods by Cartographic Aerial Mapping, Inc. for Brady Surveying Company dated June 13, 2008 and Landair Surveying, Inc. dated March 24, 2000. June 2015 2 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\facility plan.docx 1.4 Facility Report 15A NCAC 13B .0537(e) This Facility Report includes a discussion of facility information related to the proposed waste stream, landfill capacity, and special engineering features. 1.4.1 Waste Stream Moore County, North Carolina (County) owns and operates the Moore County Landfill (Landfill), located on State Highway 5 in southwestern Moore County, to manage C&D waste, yard waste, white goods, electronics waste, scrap tires, and emergency storm debris generated within the county. The landfill has been constructed in four phases totaling 21.7 acres. 1.4.1.1 Types of Waste The landfill will accept C&D waste as defined by NCDENR. This includes waste generated solely from the construction, remodeling, repair, or demolition of pavement, buildings, or structures. C&D waste does not include municipal or industrial wastes that might be generated by the ongoing operations at buildings or structures. Unacceptable waste is defined in the Operations Plan. 1.4.1.2 Disposal Rates The anticipated average daily intake and disposal rate is estimated at 89 tons per day. This rate equates to an average monthly disposal rate of 1,935 tons per month assuming 260 operational days per year. 1.4.1.3 Service Area It is anticipated that the Moore County Landfill facility will receive C&D waste only from Moore County. 1.4.1.4 Waste Segregation The landfill only accepts permitted C&D waste and any materials that may pose health hazards, cause fires, or negatively impact the environment are considered unacceptable. Signs are posted at the facility stating the permitted types of waste and the location of the appropriate disposal area. Waste screening is accomplished through random inspections at the scale house and the tipping area. Employees are trained to detect and handle hazardous waste. Hazardous waste detected at the scale house is not permitted into the landfill and hazardous waste detected at the tipping area is isolated by installing a berm around the area. The Solid Waste Manager will notify NCDENR-Division of Waste Management (DWM) within 24 hours of a hazardous waste incident. The hauler will be responsible for removing hazardous waste from the property and if the hauler is not identified, the landfill will remove and dispose the waste appropriately. June 2015 3 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\facility plan.docx 1.4.1.5 Equipment Requirements Specific equipment requirements will vary depending on landfill operations and additional equipment may be used as necessary. Equipment will be maintained and serviced according to the manufacturer's recommendation and operating and service manuals will be kept at the facility and followed. Generally, landfill equipment use will be associated with the following tasks: • Cell construction/preparation • Spreading and compacting waste • Spreading cover soil • Site maintenance and clean-up • Extinguishing fires along with other measures As the volume of the waste stream and material handling change (e.g., at start-up, during peak daily handling times, or during peak days), the number and type of machinery needed to perform daily operations will change. As of June 2015 the landfill maintained the following equipment onsite: • 444-J John Deere Rubber Tire Loader • 953-B Caterpillar Track Loader • 613 Caterpillar Scraper Pan • 370-A Rex Compactor • 670-C John Deere Motor Grader • 555-D Ford Backhoe • 5400 John Deere Tractor The equipment used on site may be modified as necessary to facilitate efficient and compliant operations. The following is a sample list of equipment that may be used at the facility to perform necessary operational functions. 1.4.2 Landfill Capacity and Soil Resources The life expectancy of the landfill is based on the available airspace, anticipated disposal rate, and calculated specific gravity of waste. The available airspace is determined by comparing the topography of the site to the design intermediate cover grades. The disposal area is approximately 21.7 acres, and the top intermediate cover grades are approximately 455 feet above mean sea level. The final side slopes will be 3H:1V to an elevation of 440 feet, and will transition to an 8% slope up to 445 ft. The total net capacity for Phases I-IV is approximately 1,451,400 cubic yards, using the design intermediate cover grades. Of the total net capacity, it is estimated that approximately 412,000 cubic yards of storage is remaining. The disposal of C&D materials for the previous 30 months of operations (from November 01, 2012 to April 30, 2015) was determined to be 58,070 tons as shown in the Moore County Material Analysis Report from the Moore County Landfill scale house. This equates to a disposal rate of 23,228 tons per year. June 2015 2 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\facility plan.docx The specific gravity of waste was previously determined by analyzing the total weight and volume of disposed waste for a given timeframe. A specific gravity of 844 pound per cubic yard (lb/CY) was calculated based on the January 2005 topographic surveys and increased to 938 lb/CY based on the June 2008 topographic surveys. A specific gravity of 938 lb/CY will be assumed for the calculations of the remaining operating life of the landfill. Based on the available airspace, disposal rate, and calculated specific gravity of waste, the landfill is expected to remain operational until March 2024. The table below outlines the net capacity of the landfill. Table 1: Phase Volumes PHASE VOLUMES Cell Acres Waste Capacity (million cy) Net Per Cell Cumulative Net Cumulative Gross 1 and 2 8.41 0.61 0.61 0.67 3 3.97 0.44 1.05 1.13 4 4.64 0.40 1.45 1.55 5 4.68 0.31 1.76 1.87 Total 21.7 1.76 1.87 Soil for operations such as daily and intermediate cover, are utilized from the excavation of the Cell 5 area. The cap system will consist of an 18-inch-thick soil layer with a permeability of 1x10-5 cm/s or less, and an 18-inch-thick vegetative support layer capable of sustaining native plants. Construction appurtenances, such as roads and berms, will generally be constructed from onsite soil. The following table summarizes the estimated soil requirements. A potential onsite borrow area is identified on Drawing G-01 which may yield 250,000 CY of soil for either landfill construction or operations. Additional evaluation of the borrow area will be needed to better determine the quantity and appropriate uses for the borrow material. June 2015 3 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\facility plan.docx Table 2: Soil Requirements SOIL REQUIREMENTS Material Minimum Quantity CY) Anticipated source Operations 30,000 On-site Miscellaneous Structural Fill 12,000 On-site 18” Soil Cap 56,000 On-site or off-site 18” Vegetative Support Layer 56,000 On-site or off-site Total Needs 154,000 Borrow Area(s) 250,000 On-site • The soil required for operations assumes a 10:1 waste-to-cover ratio (300,000 CY waste to 30,000 CY of cover). • The soil required for miscellaneous structural fill assumes 25:1 waste-to-soil ratio. • The soil cap and vegetative support layer assume a 0.1-foot overbuild. • The on-site borrow area soils may not be acceptable for all uses. 1.4.3 Special Engineering Features 1.4.3.1 Leachate Management No leachate management system is currently being utilized at the Moore County Landfill as it is not required by regulation. 1.4.3.2 Landfill Gas Management To protect public health and safety in the vicinity of the landfill, landfill gas produced by the decomposition of C&D waste will be controlled and monitored during the operational, closure, and post- closure periods. A gas monitoring program will be implemented for the purpose of maintaining the concentration of methane gas below the following regulatory levels, if necessary: • The concentration of methane gas generated is not to exceed 25 percent of the lower explosive limit (LEL) for methane in on-site structures. • The concentration of methane gas is not to exceed the LEL for methane at the facility property boundary. Landfill gas is a by-product from the decomposition of organic waste in a C&D Landfill. The major components of landfill gas are methane and carbon dioxide. Other gases, such as volatile organic compounds, may be present in trace quantities. June 2015 4 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\facility plan.docx Gas monitoring will be performed during the active life of the landfill and throughout the closure and post- closure periods. At a minimum, quarterly monitoring of explosive gases will be conducted at all gas detection probes and in structures at the landfill. As required by NCDENR guidance, methane and hydrogen sulfide will be monitored. If additional structures are built, the monitoring program will be expanded to include the new structures. Gas detection probes will be installed around the boundary of the waste disposal unit. Probes should not be needed where site topography permits gas to be released to the atmosphere before it migrates to the property boundaries, or where the site is bound by surface water features. The facility’s Operation Plan contains more detailed information regarding landfill gas management. 1.4.3.3 Containment and Environmental Controls Protective Final Cover System A protective final cover system will be implemented at the completion of landfill operations in order to limit infiltration of precipitation into the waste mass and minimize creation of leachate and landfill gas. A properly engineered final cover system, which is properly maintained, will significantly limit precipitation from entering the waste mass, and thus minimize the formation of leachate and prevent the emission of landfill gas, which is a known greenhouse gas. The goal of a final cover system is to minimize long-term maintenance and to protect human health and the environment from both leachate and greenhouse gases. The cap system will consist of a soil liner layer of at least 18 inches with permeability no greater (slower) than 1.0 x 10-5 cm/sec and a vegetative support layer of at least 18 inches capable of sustaining native plant growth. Within 6 months of the anticipated date of final receipt of waste, Moore County will select the material(s) to be used for the layer of restricted permeability. Three choices currently anticipated are: • 18 inches of on-site 10-5 cm/sec soils • 18 inches of off-site 10-5 cm/sec soil • Geosynthetic liner (e.g. GCL, LLDPE) typically slower than 5 x 10-9 cm/sec. At that time, the existing soils available for capping the waste will be evaluated for compliance with the cap system requirements. If soils of sufficient quantity and quality exist, a plan to incorporate those soils into the cap system may be proposed for approval by NCDENR. The County may evaluate the economic cost of a soil cap and a geosynthetic cap. If a geosynthetic cap is cost effective, then it may be proposed for approval by NCDENR. Construction methods shall be based upon the type and quality of the borrow source and shall be verified in the field by constructing a test pad. A professional engineer shall certify that the installation of the permeability restricted layer conforms to the plans approved by the NCDENR- DWM. The vegetative support layer will consist of no less than 18 inches of earthen material capable of sustaining native plant growth. It is anticipated that this layer will consist of suitable on-site or off-site June 2015 5 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\facility plan.docx borrow material. The materials of this layer will be selected considering soil type, pH, erodibility, side slope drainage, and other factors. The vegetation will be selected based upon the following characteristics: • Species of grasses which are locally adapted and resistant to drought or temperature extremes. • Having roots which will not disrupt the low permeability layer. • Ability to thrive in low nutrient soil and develop a good stand to resist erosion. • Ability to survive and function with little or no maintenance. All cover material will be free of putrescible material, solid waste, construction debris, and other deleterious materials. 1.4.3.4 Other Solid Waste Management Areas A drop-off/recycling area is also available for the general public and is located at the entrance to the facility. The drop-off/recycling area accepts aluminum cans, steel cans, glass, newspapers, magazines, mixed paper, scrap metal, white goods, electronics waste, scrap tires, and yard waste. These materials are sent their final disposal destination as described in the Operations Plan and are not disposed of in the landfill. Staging Areas for emergency storm debris, yard waste, white goods, electronics waste, scrap tires, and the citizen drop off area are shown on the Overall Site Plan. 1.4.3.5 Special Engineering Features There are no special engineering features proposed for the facility at this time.

This plan was prepared in general accordance with Rule .0542 and provides details of the procedures and policies, which shall be implemented throughout the life of the proposed landfill expansion. 1.1 Operation Drawings Drawing P-02 depicts the anticipated fill progression and yearly contour transitions. As waste is placed, storm water management features such as drainage benches, side slope swales, and slope drains will be installed. 1.2 Waste Acceptance and Disposal All vehicles must stop at the scale house located at the entrance of the existing landfill facility and visitors are required to sign-in. All refuse transportation vehicles are weighed and the content of the load assessed. The scale attendant(s) requests from the driver of the vehicle entering the landfill a description of the waste it is carrying to confirm that unacceptable waste is not allowed into the landfill. The attendant(s) then visually checks the vehicle as it crosses the scale. The landfill will accept only those solid wastes it is permitted to receive. The County will notify the North Carolina Department of Environment and Natural Resources (NCDENR) – Division of Waste Management (DWM) within 24 hours of attempted disposal of any waste the landfill is not permitted to receive, including waste from outside the area the landfill is permitted to serve. Asbestos waste will be managed in accordance with 40 CFR 61. The regulated asbestos waste must be covered immediately with soil in a manner that will not cause airborne conditions and must be disposed of separate and apart from other solid wastes: 1. In a defined isolated area within the footprint of the landfill, or 2. In an area not contiguous with other disposal areas. Separate areas must be designated so that asbestos is not exposed by future land-disturbing activities. Wastewater treatment sludge must not be accepted for disposal. Wastewater treatment sludge may be accepted, with the approval of the NCDENR-DWM, for utilization as a soil conditioner and incorporated into, or applied onto, the vegetative growth layer. The wastewater treatment sludge may not be applied at greater than agronomic rates or to a depth greater than six inches. June 2015 2 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx 1.3 Waste Exclusions The following wastes will not be disposed of at the C&D landfill unit. 1. Containers such as tubes, drums, barrels, tanks, cans, and bottles unless they are empty and perforated to ensure that no liquid, hazardous or municipal solid waste is contained therein. 2. Garbage as defined in G.S. 130A-290(a)(7). 3. Hazardous waste as defined in G.S. 130A-290(a)(8), to also include hazardous waste from conditionally exempt small quantity generators. 4. Industrial solid waste unless a demonstration has been made and approved by the NCDENR- DWM that the landfill meets the requirements of Rule .0503(2)(d)(ii)(A). 5. Liquid wastes. 6. Medical waste as defined in G.S. 130A-290(a)(18). 7. Municipal solid waste as defined in G.S. 130A-290(a)(18a). 8. Polychlorinated biphenyls (PCB) wastes as defined in 40 CFR 761. 9.

The following wastes will not be received if separate from C&D waste. 1. Lamps or bulbs including but not limited to halogen, incandescent, neon or fluorescent. 2. Lighting ballast or fixtures; thermostats and light switches. 3. Batteries including but not limited to those from exit and emergency lights and smoke detectors. 4. Lead pipes. 5. Lead roof flashing. 6. Transformers. 7. Capacitors. 8. Copper chrome arsenate (CCA). 9. Creosote treated woods. Waste accepted for disposal in a C&D landfill unit must be readily identifiable as C&D waste and must not have been shredded, pulverized, or processed to such an extent that the composition of the June 2015 3 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx original waste cannot be readily ascertained. However, C&D waste that has been shredded, pulverized or otherwise processed may be accepted for disposal from a facility that has received a permit from an authorized regulatory authority which specifies such activities are inspected by the authority and whose primary purpose is recycling and reuse of the C&D material. A waste screening plan and waste acceptance plan must be made available to the NCDENR-DWM upon request. A container will be located near the working face to collect and remove banned and/or recyclable items. Moore County, or its employees, will not knowingly dispose any type or form of C&D waste that is generated within the boundaries of a unit of local government that by ordinance: 1. Prohibits generators or collectors of C&D waste from disposing that type or form of C&D waste, or 2. Requires generators or collectors of C&D waste to recycle that type or form of C&D waste. 1.4 Waste Inspection In order to assure that prohibited wastes are not entering the landfill facility, screening programs will be implemented. Waste shall be screened at both the scale house entrance and at the working face by trained personnel. Screening programs for visual and olfactory characteristics of prohibited wastes will be an ongoing part of the landfill operation. Approximately one percent of all waste trucks bound for the C&D landfill will be selected for a more thorough screening. Selected vehicles will be directed to an area of intermediate cover adjacent to the working face where the vehicle will be unloaded. The waste will be inspected for municipal solid waste (MSW), liquid waste, hazardous waste, PCB waste, and other banned items. Waste is carefully spread using suitable equipment. An attendant trained to identify wastes that are unacceptable inspects the waste discharged at the screening site. If unacceptable waste is found, the load will be isolated and secured by constructing a berm around the area. For regulated hazardous or PCB wastes, the Solid Waste Division Manager will notify officials of the NC DENR, Division of Waste Management. The hauler is responsible for removing unacceptable waste from the landfill property. If no unacceptable waste is found, the load will be pushed to the working face and incorporated with the daily waste. For each vehicle screened, a random waste screening inspection form will be filled out and will be kept on-site. An inspection form should include the following information: The date and times wastes were received for inspection Source and type of wastes Vehicle and driver identification All observations made by the inspector June 2015 4 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx Final disposition of waste after inspection Records of information gathered as part of the waste screening programs will be maintained at the landfill during the active life of the C&D unit and as long as required by the County and the Division. 1.5 Cover Material Requirements Cover soil will be placed on solid waste with six inches of earthen material when the waste disposal area exceeds one-half acre and at least once weekly. Cover will be placed at more frequent intervals if necessary to control disease vectors, fires, odors, blowing litter, and scavenging. A notation of the date and time of the cover placement will be recorded in the operating record. Areas which will not have additional wastes placed on them for three months or more, but where final termination of disposal operations has not occurred, will have at least 6 inches of cover soil and be stabilized with vegetative ground cover or other stabilizing material. The County may request use of alternative materials or an alternative thickness of cover from the NCDENR-DWM by demonstrating that the alternative material or thickness controls disease vectors, fires, odors, blowing litter, and scavenging without presenting a threat to human health and the environment. 1.6 Spreading and Compacting Requirements Incoming waste at the landfill will be confined to the smallest working face feasible. Appropriate control devices such as berms, fences, and cover material will be used as needed to prevent windblown debris. At the conclusion of each operating day, all windblown material resulting from the operation will be collected and disposed of by the staff. 1.7 Disease Vector Control The County will prevent or control on-site populations of disease vectors using techniques appropriate for the protection of human health and the environment. For purposes of this item, "disease vectors" mean any rodents, flies, mosquitoes, or other animals or insects, capable of transmitting disease to humans. Vectors are generally attracted by opportunities for food and shelter. C&D waste is not a food source for many vectors. Vectors seeking shelter in the waste mass can be discouraged by covering of the waste and proper grading to prevent ponding of water. If vectors become a problem, a licensed exterminator or other legal means of control shall be implemented. June 2015 5 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx 1.8 Air Criteria and Fire Control 1.8.1 Landfill Gas Monitoring The County has monitored methane at the facility quarterly since March 2000. Historical monitoring results submitted to NCDENR- DWM indicate the presence of methane above the lower explosive limit (LEL) at locations associated with the MSW unit (i.e., GP-10, MW-6, and MW-15). However, data from the 2015 monitoring events show the presence of methane above the LEL at GP-14, which is close to the C&D unit and in the yard waste management area. The source of the methane is likely the yard waste area rather than the C&D unit. The County has completed corrective measures including: 2005: a trenching and venting network consisting of a trench and 12 passive LFG vents was installed 2007: trenching and venting network was expanded via 12 additional LFG 7. 2014: three in-waste passive gas vents (GV-30, GV-31, and GV-32) were installed in February 2014 as part of the Contingency Plan Update and Implementation Plan-Revised approved by NCDENR on June 5, 2013 related to the Assessment of Corrective Measures for to address volatile organic constituents in groundwater samples from monitoring wells at the MSW facility. Additional corrective measures for methane may be required in the future as part of methane and groundwater compliance activities. The following sections discuss the proposed locations of landfill gas monitoring wells, the monitoring of structures, and the monitoring frequency. 1.8.1.1 Landfill Gas Monitoring Well Locations Nine landfill gas monitoring wells (GP-1 through GP-9), the headspace of two monitoring wells (MW-6 and MW-15), and three structures (maintenance building, transfer station, and scalehouse) are monitored quarterly for methane and hydrogen sulfide. The network monitors both the active C&D facility and the adjacent closed MSW unit. The locations on these landfill gas monitoring wells are shown on Drawing G-01. 1.8.1.2 Structure and Ambient Sampling As stated above, three structures (maintenance building, transfer station, and scalehouse) are monitored quarterly as part of the landfill gas monitoring network. 1.8.1.3 Landfill Gas Monitoring Frequency Landfill gas monitoring will be performed on a quarterly basis as required in Title 15A NCAC 13B.0544(d)(2)(B) and in accordance with NCDENR November 2010 Landfill Gas Monitoring Guidance. In the event that the explosive action level or compliance level is exceeded, the monitoring frequency will increase to monthly until three consecutive months have passed without a methane action level or compliance level exceedance, at which time the monitoring frequency will revert to quarterly. June 2015 6 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx 1.8.1.4 Landfill Gas Sampling Procedures The following sections outline the recommended procedures for performing required landfill gas monitoring well and facility structure monitoring for methane gas. 1.8.1.5 Detection Equipment Used The GEM-2000 Plus is the preferred monitoring device for monitoring landfill gas monitoring wells. Alternatively, a digital or analog manometer combined with a vacuum-pump-equipped monitoring device designed to measure methane gas and hydrogen sulfide concentrations can be used. In addition to the monitoring device(s), the following equipment and documents should be readily available during monitoring events: Copy of the facility’s Landfill Gas Monitoring Plan A copy of the Operation Manual(s) for the equipment being used during monitoring Blank copies of the Landfill Gas Monitoring Log Calibration gas (if applicable) Barometer (if available) Personal protection equipment (site specific) Necessary keys (site specific) Gas monitoring equipment should be calibrated daily, prior to use in the field. Generally, one calibration per day is sufficient. In some instances where highly variable concentrations are being observed, it may be necessary to re-calibrate the monitoring device during the work day to ensure that instrument drift is minimal. Instrument drift can be checked with a calibration gas of known concentration. If more than a 3% difference is observed between the instrument reading and the gas standard during an instrument drift check, the unit should be recalibrated. Field calibration should be performed in accordance with the instrument manufacturer’s recommendations using an approved gas standard. Generally, when landfill gas monitoring wells are monitored it is best to calibrate the unit with standard composed of 15% or less methane. Calibration activities should be documented on a calibration log. Gas monitoring equipment should also be calibrated by the manufacturer or supplier in accordance with the recommended schedule for that instrument. 1.8.1.6 Sampling Procedures After calibrating the monitoring instrument, record the weather conditions at the site, including the barometric pressure and ambient temperature. The temperature and barometric pressure should be logged at the beginning and ending of each field day. Site-specific barometric pressure readings are June 2015 7 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx preferred. In the event that a barometer is not available, barometric pressure readings from a nearby weather station can be used. Monitoring should be conducted between noon and sunset. 1.8.1.7 Landfill Gas Monitoring Well Gas Concentration Measurements Before connecting the monitoring instrument to the landfill gas monitoring well, purge the connector tube for at least one minute prior to taking reading. Connect the instrument tubing to the landfill gas monitoring well cap fitted with a stopcock valve or quick connect coupling. Open the valve and record the initial reading and then the stabilized reading for methane and hydrogen sulfide. A stable reading is one that does not vary more than 0.5 percent by volume on the instrument’s scale. Turn the stopcock valve to the off position and disconnect the tubing. Proceed to the next landfill gas monitoring well and repeat. 1.8.1.8 Facility Structure Gas Concentration Measurements Confined spaces, which require a confined space permit to enter, are excluded from these general monitoring requirements. The following monitoring plan applies to the structures at the facility: After entering the designated structure, turn on the gas monitoring device and vacuum pump and traverse the accessible and open area on the first floor of the facility structure while holding the intake hose for the monitoring device at shoulder height. During the traverse, observe the meter for any measurable methane concentrations and record the time and concentration on the monitoring log. If measurable methane concentrations are observed in a facility structure, attempts to identify the source of the methane should be made. If the facility structure is elevated and has a crawl space, the crawl space beneath the facility should be monitored from outside of the structure on accessible sides to determine if the methane gas is migrating into the structure from the crawl space. Do not enter a crawl space beneath a structure without proper authorization and sufficient personal protection equipment, including an oxygen monitoring device, since these areas may be considered confined spaces. If the facility structure is constructed on grade, ambient air near the exterior walls at floor level or near cracks in the floor, if exposed, should be monitored to determine if gas is migrating upward along or through the foundation. 1.8.1.9 Well Decommissioning Procedures If a landfill gas monitoring well requires decommissioning, an abandonment record shall be submitted to NCDENR within 30 (thirty) days of the decommissioning. The landfill gas monitoring well(s) shall be decommissioned in accordance with 15A NCAC 2C .0113(d) by a certified well driller. The landfill gas monitoring well(s) shall be over-drilled and sealed with grout via tremie-pipe if located in the future waste footprint. The landfill gas monitoring well(s) shall be sealed with grout and all surface completions removed if not located in the future waste footprint. The decommissioning report will be sealed by a North Carolina Licensed/Professional Geologist. June 2015 8 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx 1.8.1.10 Record Keeping and Reporting Quarterly gas monitoring results shall be maintained by the facility operator for the life of the facility operation, closure, and post-closure care periods. Each quarterly report shall be retained on-site as part of the permanent operating record for the facility. 1.8.1.11 Landfill Gas Monitoring Form The date, time, location, sampling personnel, equipment, atmospheric temperature, reported barometric pressure, general weather conditions at the time of sampling, and the concentration of methane and hydrogen sulfide shall be recorded on the Landfill Gas Monitoring Field Log. 1.8.1.12 Sampling Reports A letter report that includes the Landfill Gas Monitoring Form, calibration certificate for the field meter, and a map showing the monitoring locations will be prepared after each monitoring event. Monitoring records will be kept on site in the facility files. In the event that explosive gas concentrations are detected in excess of allowable limits in the compliance monitoring points, a report will also be provided to the NCDENR within 5 days of the exceedance as described below. 1.8.1.13 Permanent Record Keeping A copy of each quarterly report shall be retained on-site as part of the permanent operating record for the facility. 1.8.1.14 Contingency Plan Pursuant to the 15A NCAC 13B, the compliance levels for landfill gas monitoring are 25% of the lower explosive limit (LEL) for methane and other explosive gasses (1.25% methane by volume) in facility structures (excluding gas control or recovery system components) and 100% of the LEL (5% methane by volume) for methane at the facility boundary. If either of these compliance levels is exceeded, the operator shall: Take all immediate steps necessary to protect public health and safety, including those required by the contingency plan. The contingency plan for this facility is as follows: Evacuating all personnel from any facility structure(s) exceeding the safe LEL levels Notifying local fire officials of the exceedance if there are habitable structures within 1,000 feet of the property boundary Isolating the effective area and post signs around the affected area indicating the potential health and safety risk Posting signs in the affected area indicating a “No Smoking” area Appropriate safety training for all personnel entering in the isolated area June 2015 9 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx Notify NCDENR in a written statement within five working days of learning that action levels have been exceeded, and indicate what has been done or is planned to be done to resolve the problem. Begin initial remediation actions, which may include the following activities: Additional temporary gas monitoring probe installations and sampling to determine the extent of the gas migration Increased monitoring of probes, structures, and any identified preferred flow pathways to verify concentrations and to protect human health Within 60 days of detection, implement a remediation plan for the explosive gas releases and submit it to NCDENR for amendment of the facility permit The Landfill Gas Remediation Plan shall describe the nature and extent of the problem and the proposed remedy. The plan shall include an implementation schedule specifying timeframes for implementing the corrective actions, an evaluation of the effectiveness of such corrective actions, and milestones for proceeding in implementation of additional corrective actions, if necessary to re-establish compliance. Gas control systems proposed in a Landfill Gas Remediation Plan shall be designed to: Prevent methane accumulation in on-site structures Prevent methane compliance level exceedances at the facility boundary Provide for the collection, treatment, and destruction/disposal of decomposition gases and condensate Comply with Clean Air Act requirements, as applicable 1.8.2 Fire Control 1.8.2.1 General The following protocols will be utilized for fire control at the facility: Smoking will be confined to designated areas only, away from active areas of the Landfill, fueling stations, methane vents, and other fire sensitive areas. The County will ensure that the disposal area does not violate any applicable requirements developed under a State Implementation Plan (SIP) approved or promulgated by the U.S. EPA Administrator pursuant to Section 110 of the Clean Air Act, as amended. Open burning of solid waste, except for the approved burning of land clearing debris generated on-site or debris from emergency clean-up operations is prohibited. Prior to any burning, a request must be sent to the NCDENR-DWM for review and approval. In addition, the Division of Air Quality and local fire department must approve the activity prior to burning. A notation of the date of approval and the name of the NCDENR-DWM personnel who approved the burning must be included in the operating record. Fires that develop spontaneously at the C&D unit working face will be extinguished by covering the burning area with soil. An ample supply of soil will be stored near the working face during operational hours. June 2015 10 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx Equipment must be provided to control accidental fires and arrangements must be made with the local fire protection agency to immediately provide fire-fighting services when needed. 1.8.2.2 Fire on Landfill Working Face The following actions should be taken if a fire develops at the working face. 1. Notify the supervisor of the existence of the fire. 2. If the supervisor determines the fire is controllable, follow his instructions. Compactors should be used to cut and push burning garbage away from working face and then cover with soil until fire is extinguished. 3. If the supervisor determines the fire to be uncontrollable, evacuate the area immediately using predetermined evacuation paths. 4. Concurrently, the supervisor notifies the scale attendant via two-way radio or cell phone that a fire has developed on the C&D unit and status of the fire. If it is determined that the fire is uncontrollable, advise the scale attendant to call 911 for fire and rescue. If the fire is deemed to be controllable, inform the scale attendant of steps taken to control the fire and also when the fire is extinguished. The scale attendant will not allow additional waste disposal vehicles to enter the landfill until the fire has been extinguished. The scale attendant will direct emergency vehicles to the location of the fire. 5. The supervisor and landfill employees will assist fire and rescue personnel as directed by the senior fire officer. 6. The supervisor will ensure that all landfill emergency equipment is prepared for reuse before resuming normal operations. 1.8.2.3 Fire in Landfill Equipment The main goal in controlling a fire involving landfill equipment is for the equipment operator to evacuate to safety. The following steps should be followed in case of a fire involving landfill equipment. 1. Evacuate the equipment immediately upon discovery of a fire. 2. Inform the supervisor of the exact location of the fire, the equipment involved, and whether any individuals remain in the equipment. 3. Follow the supervisor's instructions to control the fire and to allow rescue of injured individuals remaining in the equipment. 4. Concurrently, the supervisor notifies the scale attendant via two-way radio of the existence of the fire involving equipment and if any personnel are injured and/or remain in the equipment. The scale attendant will call 911 for fire and rescue if needed and will dispatch a vehicle to landfill entrance to escort emergency vehicles to the location of the fire. The scale attendant will not allow additional vehicles to enter the landfill until the fire is extinguished. June 2015 11 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx 5. If the supervisor deems the fire to be controllable and no injuries have occurred to personnel, the fire will be extinguished by appropriate measures (i.e., fire extinguisher). If the supervisor determines assistance from local fire and/or rescue squad will be required, efforts to control the fire to prevent spreading will be taken until the fire and rescue squad arrive. These measures include: preliminary first aid on injured personnel continuing to soak burning equipment with water from water truck moving other equipment from vicinity of burning equipment directing vehicles currently unloading waste away from the disposal area 1.8.2.4 Explosions Fires and explosions that occur at the landfill require verbal notice to the NCDENR-DWM within 24 hours and written notification within 15 days. Written notification must include the suspected cause of fire or explosion, the response taken to manage the incident, and the action(s) to be taken to prevent the future occurrence of fire or explosion. In the event of an explosion at the C&D unit, the following procedures should be followed: 1. Evacuate to a safe area. 2. Assist in rescue of injured personnel. 3. The supervisor will notify the scale attendant of the occurrence of the explosion and the results of such explosion (fire, injured personnel, and malfunctioning equipment). The scale attendant will dial 911 as instructed by the supervisor. The scale attendant will not allow additional waste vehicles to enter the facility. 4. Fires that occur as a result of the explosion will be controlled whenever possible. 5. The supervisor and landfill employees will assist fire and rescue personnel as directed by the senior fire officer. 6. The supervisor will ensure that all emergency equipment is prepared for reuse before resuming normal operations. 7. The supervisor will alert the scale attendant when the situation is under control and when normal operations can resume. 8. The supervisor will prepare a written report of the incident and submit it within three working days. 1.9 Access and Safety Requirements Entry to the site will be limited to landfill personnel, approved contractors, approved waste haulers, visitors, and other properly identified persons whose entry is authorized by the site management. The County reserves the right to restrict access to the site. Visitors may be allowed near the active area only when accompanied by a site representative June 2015 12 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx 1. The landfill will be adequately secured by means of gates, chains, berms, fences and other security measures approved by the NCDENR-DWM to prevent unauthorized entry. The landfill entrance is protected by a 6-foot chain link fence with triple strands of barbed wire to prevent unauthorized entry into the site. Areas currently not protected by fencing are inaccessible by motor vehicle due to steep slopes, berms, water barriers, trees, etc. The disposal areas will be surrounded on all sides by natural barriers, fencing, or an equivalent means of controlling vehicular access and preventing illegal disposal. Gates will limit access, and such gates will be securable and equipped with locks. 2. In accordance with G.S. 130A-309.25, an individual trained in landfill operations must be on duty at the site while the facility is open for public use and at all times during active waste management operations to ensure compliance with operational requirements. 3. The access road to the working face will be of all-weather construction and kept in good condition. A paved road within the perimeter of the property facilitates two-way traffic to the landfill units. 4. Dust will be controlled on the access roads applying water to the roads on an as needed basis. 5. An entrance sign will be posted stating the facility’s name, permit number, and operating hours. Additional signs will be posted for allowable speed limit, promote an orderly traffic pattern to and from the discharge area, and maintain efficient operating conditions. Proper signage will be placed in high visibility areas, informing facility users that no hazardous or liquid wastes can be received. 6. The removal of solid waste from the landfill is prohibited unless the operational plan includes a recycling program which has been approved by the NCDENR-DWM. The general public is prohibited from removal activities on the working face. 7. The access road to the site and access roads to monitoring locations will be of all- weather construction and maintained in good condition. 1.10 Erosion and Sedimentation Control Requirements Adequate sediment control measures consisting of vegetative cover, materials, structures or devices will be utilized to prevent sediment from leaving the landfill and preventing excessive on-site erosion of the landfill. An Erosion and Sediment Control Plan has been approved by the NC Division of Land Resources, Land Quality Section. Refer to the “Letter of Approval” for the Erosion and Sediment Control Plan from the NC Division of Land Resources, Land Quality Section dated November 25, 2009. June 2015 13 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx 1.11 Drainage Control and Water Protection Requirements The fill sequence of Phases I-IV is illustrated on Drawing P-02. As filling operations are initially proceeding, stormwater from the unfilled portion of Cell 5 is kept out of the fill area. Cell 5 has been designed with maximum waste side slopes of 3H:1V and maximum 8% top slopes to promote runoff and prevent ponding over or in the waste. Side slope terraces and perimeter drainage channels at the toe of the slope will provide runoff, erosion, and sediment control. The drainage channel will allow for the movement of surface water from landfilling activities and provide a settling zone for sediments carried from the site. The channel is constructed to allow drainage via sediment basins through natural outfalls and tributaries to Horse Creek. Sediment basins will also prevent the discharge of pollutants that violate requirements of the Clean Water Act, including, but not limited to, NPDES requirements, into the waters and wetlands of the United States. The County currently monitors the facility under general permit number NCG120000, Certificate of Coverage number NCG120084. As described in the approved Water Quality Monitoring Plan, the landfill has a comprehensive surface and groundwater monitoring program to provide early detection of any leachate migration problems. In the event any constituents are detected above the allowable limits, measures will be taken to begin assessing the extent of contamination. If necessary, corrective actions will be taken to prevent pollution of waters or wetlands. The following operational controls will be used. 1. Surface water shall be diverted from the operational area. 2. Surface water shall not be impounded over or in waste. 3. Solid waste shall not be disposed of in water. 1.12 Survey for Compliance Within 60 days of the County’s receipt of the NCDENR-DWM's written request, the County must conduct a survey of the active or closed portions of the landfill in order to determine whether operations are being conducted in accordance with the approved design and operational plans. The County must report the results of the survey, including a map produced by a North Carolina registered land surveyor survey, to the NCDENR-DWM within 90 days of receipt of the NCDENR- DWM's request. 1.13 Operating Record and Recordkeeping Requirements Records for facility inspections, tonnage, waste generators, and employee training will be kept at the facility and made available to the NCDENR-DWM upon request within a reasonable period of time. June 2015 14 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx Records for gas/groundwater monitoring results and corresponding analytical data, Closure/Post Closure cost estimates, and financial assurance documentation will be kept in the office of the Solid Waste Administrator. The information will be made available to the NCDENR-DWM upon request within a reasonable period of time. Copies of the Operation Plan will be kept at the facility and the office of the County Public Works Director. All information contained in the Operating Record will be furnished to the NCDENR-DWM according to the permit or upon request, or be made available for inspection by the NCDENR-DWM. The County will record and retain at the facility, or in an alternative location near the facility, the following information: 1. Records of random waste inspections, monitoring results, certifications of training, and training procedures required by Rule .0544. 2. Amounts by weight of solid waste received at the facility to include, consistent with G.S. 130A-309.09D, county of generation. 3.

Any closure or post-closure monitoring, testing, or analytical data as required by Rule .0543. 5. Any cost estimates and financial assurance documentation required by Rule .0546. 6. Notation of date and time of placement of cover material. 7. All audit records, compliance records and inspection reports. The Operating Record will also include the following. 1. A copy of the approved operation plan and the engineering plan required by Rule .0539. 2. A copy of the current Permit to Construct and Permit to Operate. 3. The Monitoring Plans. 1.14 Exceptional Operations In the event of a fire, explosion, spill, natural disaster, long-term power outage, major equipment breakdown or other atypical event that effects the normal operation of the landfill, the landfill manager, with the assistance of others, will develop and implement an event specific contingency plan. If the plan requires the redirection or suspension of service, the public and NCDENR will be notified as appropriate. The landfill manager will be responsible for providing the personnel and equipment necessary to handle exceptional operation events in a manner consistent with the requirements of the permit. June 2015 15 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx 1.15 Miscellaneous Waste Management 1.15.1 Moore County Landfill Collection Center A manned solid waste collection center is located near the entrance of the landfill. The collection center is approximately a half acre in size and accepts household waste, plastic, aluminum, newspaper, and magazines. The County provides containers labeled for each of the acceptable materials. Space is maintained between containers for facilitating inspection and firefighting. Users of the collection center do not cross the scales but must enter and exit thru a gate before the scale house. The operating hours are Monday through Saturday from 7:00 a.m. to 7:00 p.m. The site is closed on the following four holidays: New Year’s Day, Independence Day, Thanksgiving Day, and Christmas Day. When a container is full, it is removed from the collection center within 24 hours by Moore County staff. The following are the final disposal destinations for each accepted material. Household Waste On-site transfer station Permit # 63-02T Plastic, Aluminum, and Paper Products North Davidson Garbage and Recycling Center 4157 Old US Hwy 52 Lexington, NC 27295 1.15.2 Scrap Tires Scrap tires are currently collected free of charge at the landfill. It is estimated that 80 percent of the tires collected are passenger tires, 15 percent truck tires, and 5 percent large off-road tires. Two box trailers, approximately 50’ in length, are available for tire collection located in only one area of the Landfill (refer to Overall Site Plan, G-01). Users are responsible for unloading their scrap tires and stacking them directly into these trailers. When a trailer is full, it is removed from the landfill and an empty trailer is brought to the landfill. Approximately one trailer per week is collected and removed from the landfill. The final disposal destination of the tires is currently: Central Carolina Tire Disposal 1616 McKoy Town Rd. Cameron, NC 28326 1.15.3 White Goods/Scrap Metal White goods and scrap metal are collected and stored at the landfill on a gravel pad that is approximately 300’ by 300’ in only one area of the Landfill (see Overall Site Plan G-01). The County June 2015 16 Project No. 073-9615014 g:\projects\moore county\2015 permit renewal\operations plan.docx is currently under contract with Metal Recycling Services, Inc. to extract and collect the refrigerant from the white goods and remove the white goods and scrap metal from the landfill. The white goods and scrap metal are not allowed to exceed the available storage area. Extraction of refrigerant from the white goods takes place quarterly. White goods and scrap metal are removed from the site every six weeks or when 125 tons have been collected. More frequent collection may occur upon mutual agreement of the County and Recycling Services, Inc. 1.15.4 Electronics Waste Electronics waste collected and stored at the landfill on a covered concrete pad adjacent to the white goods staging area (see Overall Site Plan G-01). These materials are sent to a third party facility for proper disposal and recycling. The final destination of these materials is currently: Southern Environmental Solutions of the Carolinas, Inc. 895 State Rd 1403 Peachland, NC 28133 1.15.5 Yard Waste Two yard waste staging areas are provided at the facility and are located directly west and northwest of the active C&D landfill (see Overall Site Plan G-01). The facility will store and/or stockpile unprocessed vegetation and ground material in the designated areas and these materials will not be distributed to the public or composted by the County. The material will be transported to either a compost facility, a wood waste burner, or used on-site. Refer to the Moore County Landfill Yard Waste Treatment and Processing Facility Operations Plan, last revised January 2013, for more details. 1.15.6 Transfer Station An on-site transfer station was constructed in 1993 for handling of MSW upon the closure of the MSW landfill located at the facility. The structure is located south of the landfill (see Overall Site Plan G-01) and operates under Permit #63-02T. The transfer station is handled separately from this Permit Amendment and operations are currently contracted to Republic Services of NC, LLC. 1.15.7 Emergency Storm Debris Management Area An emergency storm debris management area is located north of the landfill (see Overall Site Plan G-01) and is provided by the facility to assist the County with managing debris associated with cleanup efforts conducted due to severe weather conditions.
