The unlined MSW area opened in 1982 and stopped receiving waste prior to October 9, 1991. The capped MSW stopped receiving waste in December of 1997, and was closed in 1998. The capped MSW was certified in March, 2000. The closed MSW areas have a minimum of two feet of final cover. The total permitted C&D capacity is 1,126,540 (1997 Submittal) cubic yards. The permitted capacity is the sum of the total air space of 1,039,420 cubic yards (1997Submittal) and the final soil cover system of 87,120 cubic yards. The existing closed MSW footprint is approximately 47 acres in size.

The County will cap their landfill within 180 days after the final receipt of solid waste. The cap system will consist of 12 inches bridging material (temporary cover), 18 inches of soil liner with a permeability no -5 greater than 1.0 x 10 cm/sec, and 18 inches of protective/erosive layer. The cap contains gas venting system consisting of a series of washed stone trenches below the soil liner that will be vented through pipes that penetrate the cap. The cap system will also include the proper seeding and mulching of the erosive layer and other erosion control devices. Landfill Capacity The Life Expectancy calculations were calculated for Phases 4-6 of development with a vertical expansion being included when a Phase is constructed adjacent to the previous Phase. Each successive phase will vary in size due to being able to expand onto the previously filled areas. The Operation Plan of the Engineering Report will delineate this more clearly. The airspace is a net volume excluding the capping requirements: Given: Life expectancy based on actual survey dated May 8th, 2009 Fiscal Year 08-09 is as follows: Life expectancy based on using the survey is 23,868 cubic yards/year (using 1200#/cy compaction rate = 14,320.8 tons/year), for the first year and an annual increase of 3.1 % for each year thereafter. Phases Airspace Available Years of Life Phase 4 = 160,920 cubic yards = 6.61 years Phase 5 = 162,386 cubic yards = 6.53 years Phase 6 = 194,738 cubic yards = 7.67 years 518,044 cubic yards 20.81 years Soil requirements for construction, daily cover and final caps for Phases 4-6 (Assume an 8:1 Trash to soil ratio) Soil needed for Intermediate and Daily Cover = 57,560 cubic yards Soil needed for Closure = 87,120 cubic yards (18 acres) Overall Soil Requirements = 144,680 cubic yards (closure and daily cover) PHASE ASTE FOOTPRINT GROSS CAPACITY STATUS (ACRE) (CUBIC YARDS) 1,2 & 3 18 518,159 ACTIVE AND PERMITTED 4 10.39 1607920 NEW PTO REQUESTED 5 VERTICAL EXPANSION 162,386 TO BE DEVELOPED 6 VERTICAL EXPANSION 1943738 TO BE DEVELOPED TOTAL 18 ACRES 1,036,203 Note: All air space and soil calculation were determined by Autodesk Land Development computer program.

The unlined MSW area opened in 1982 and stopped receiving waste prior to October 9, 1991. The capped MSW stopped receiving waste in December of 1997, and was closed in 1998. The capped MSW was certified in March, 2000. The closed MSW areas have a minimum of two feet of final cover. In addition to the C&DLF, this facility has a MSW Lined Landfill, Asbestos disposal area, a White Goods Drop -Off and Freon Extraction Area, Metals transfer pad, Small TypeA Compost Area, Closed LCID Unit, borrow sites and a Leachate Collection Lagoon. A copy of contact information on all contract haulers of recyclables shall be placed in the operating record. The County will continue a program at the landfill for detecting and preventing the disposal of hazardous and liquid wastes according to the approved existing plan. The program consists of random inspection of incoming loads at a minimum of 1 % of the weekly traffic. Landfill personnel will be trained to recognize hazardous and liquid wastes. Records will be kept on the training and the inspections. The County will monitor for explosive gases at landfill structures and the perimeter of the landfill according to the approved existing monitoring plan. The concentration of methane gases generated by the landfill cannot exceed 25 percent of the lower explosive limit for methane in the structures, and it cannot exceed 100 percent of the lower explosive limit for methane of the landfill property boundary. If methane gas is found to exceed the acceptable limits at either the property boundary or landfill structures, it is the County's responsibility to do the following: 1. Immediately take all necessary steps to ensure protection of human health, (i.e. no smoking, etc.), temporarily abandon the structure and notify the Division of Waste Management(Division). 2. Within seven days of detection, place in the operating record the methane gas levels detected and a description of the steps taken to protect human health; and 3. Within 60 days of detection, implement a remediation plan for the methane gas releases, place a copy of the plan in the operating record, and notify the Division that the plan has been implemented. The plan will describe the nature and extent of the problem and the proposed remedy. Off -site and on -site erosion will be controlled through erosion control structures and devices. Provisions for a vegetative ground cover sufficient to restrain erosion will be accomplished within 30 working days or 120 calendar days upon completion of any phase of landfill development. The County will record and retain at the landfill an operating record of the following information: (1) Inspection records, waste determination records, and training procedures; (2) Amounts by weight of solid waste received at the landfill; (3) Gas monitoring results and any remediation plans; (4) Any demonstration, certification, findings, monitoring, testing or analytical data required for surface and groundwater monitoring; (5) Any monitoring, testing or analytical data required for closure or post -closure; (6) Any cost estimates and financial assurance documentation. All information contained in the operating record will be furnished upon request to the Division or be made available at all reasonable times for inspection by the Division. P:\ Solidwaste\G17041 Lenoir C&D Permit\documents\Permit Application.doc LHC 2/8/2017 g Ground and surface water will be sampled and analyzed according to the approved existing monitoring pIan, to 40 CFR, Part 258, Appendix I detection monitoring requirements. The monitoring frequency for all Appendix I detection monitoring constituents will be at least semiannual during the life of the facility (including closure) and the post -closure period. A minimum of four independent samples from each well (background and downgradient) will be collected and analyzed for the Appendix I constituents during the first semiannual sampling event. At least one sample from each well (background and downgradient) will be collected and analyzed during subsequent semiannual sampling events. If the County determines that there is a statistically significant increase over background for one or more of the constituents listed in Appendix i at any monitoring well at the relevant point of compliance, the County will, within 14 days of the finding, report to the Division of Solid Waste and place a notice in the operating record indicating which constituents have shown statistically significant changes from background levels. The County will establish an assessment monitoring program within 90 days. The County may demonstrate that a source other than the landfill caused the contamination or that the statistically significant increase resulted from an error in sampling, analysis, statistical evaluation, or natural variation in ground -water quality. A report documenting these demonstrations will be certified by a Licensed Geologist or Professional Engineer and approved by the Division. A copy of this report will be placed in the operating record. If a successful demonstration is made, documented, and approved by the Division, the County may continue detection monitoring. If after 90 days, a successful demonstration is not made, the County will initiate an assessment monitoring program. 3.2 Operational Requirements 1. Waste Acceptance and Disposal Requirements A .

The County will ensure that the units do 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. b. 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 at all C&DLF facilities. Prior to any burning a request will be sent to the Division for review and approval. In addition, the Division of Air Quality and local fire department must approve the activity prior to burning. The Division will determine the burning to be approved if it is one of two types of burning previously referenced. A notation of the date of approval and the name of the Division personnel who approved the burning must be included in the operating record. c. Equipment will be provided to control accidental fires. In the event of an emergency the operator(s) will call 911. The site is located in the La Grange Fire District and will be served by their volunteer fire department. Fire extinguishers are located in all buildings and on all equipment. Dirt piles are also on site to use in emergency situations. d. Fires and explosions that occur at the C&DLF require verbal notice to the Division 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. 6. Access and safety requirements a. The C&DLF will be adequately secured by means of gates, chains, beams, fences and other security measures approved by the Division of Solid Waste Management to prevent unauthorized entry. b. An attendant will be on duty at the site at all times while it is open for public use to ensure compliance with operational requirements. c. The access road to the site and monitoring locations will be of all-weather construction and maintained in good condition. d. Dust control measures will be implemented when necessary. If dust problems should arise, the County will use any reasonable means necessary to reduce it. At a minimum the County will spray water on necessary areas. Water sources for dust control will be from the existing sediment basins, existing creeks and existing on -site wells. e. Signs providing information on tipping or disposal procedures, the hours during which the site is open for pubic use, the permit number and other pertinent information will be posted at the site entrance. f. Signs will be posted stating that no hazardous or liquid waste can be received. g. Traffic signs or markers will be provided as necessary to promote an orderly traffic pattern to and from the discharge area and to maintain efficient operating conditions. h. The removal of solid waste from the C&DLF will be prohibited unless the County has included in it's operational plan a recycling program which has been approved by the Division. The general public is prohibited from removal activities on the working face. 7. Erosion and Sedimentation Control Requirements a. Adequate sediment control measures (structures or devices), will be utilized to prevent silt from leaving the landfill. P:\ Solidwaste\G17041 Lenoir C&D Pemut\documents\Permit Application.doc LHC 2/8/2017 12 �7 b. Adequate sediment control measures (structures or devices), will be utilized to prevent excessive on -site erosion. c. Provisions for a vegetative ground cover sufficient to restrain erosion will be accomplished within 30 working days or 120 calendar days upon completion of any phase of landfill development. Drainage Control and Water Protection Requirements a. Surface water will be diverted from the operational area and will not be impounded over waste. b. Solid waste will not be disposed of in water. c. Leachate will be contained on site and properly treated prior to discharge. d. The landfill will not: (i) Cause a discharge of pollutants into waters of the United States, including wetlands, that violates any requirements of the Clean Water Act, including, but not limited to, the National Pollutant Discharge Elimination System (NPDES) requirements pursuant to Section 402. (ii) Cause the discharge of a nonpoint source of pollution to waters of the United States, including wetlands, that violates any requirements of an area -wide or state-wide water quality management plan that has been approved under Section 208 or 319 of the Clean Water Act, as amended. e. The County will inspect the exterior slopes of the landfill at least weekly to determine if there are any breakouts of leachate in the slopes. If any are discovered, they will be contained immediately to assure that they will not leave the site. The containment can consist but not be limited to an earthen berm, sand bags, erosion control logs and/or anything that will contain the leachate on the slope. The repair of the breakout will require excavating into the cover soil on the slope down to the waste and into the waste to determine what is causing the leachate to come to the surface. Normally it is another layer of soil that has been used as cover and the leachate is flowing along that layer to the slope and surfacing on the slope. The lower layer of cover needs to be removed at the breakout so that the leachate that is flowing along this cover has a point where it will go vertically into the landfill instead of flowing along the soil boundary that was once either daily cover or an intermediate cover. Once this soil layer has been breached, the excavation can be filed back with stone, clean waste or any material, other than soil, that will allow the leachate to flow vertically instead of horizontally. Once the excavation has been filled with this material, the surface can be cover with soil so that surface water does not intrude into the excavation. Vegetative cover will be reestablished over the excavated area. Survey for Compliance Within 60 days of a permittee's receipt of the Division's written request, the permittee will have a survey conducted of active and/or closed portions of the units) at the facility in order to determine whether operations are being conducted in accordance with the approved design and operation plans. The permittee must report the results of the survey, including a map produced by the survey, to the Division within 90 days of receipt of the Division's request. P:\ Solidwaste\G17041 Lenoir C&D Permit\documents\Permit Application.doc LHC 2/8/2017 13 a. A survey shall be required by the Division: (i) If there is reason to believe that the operations are being conducted in a manner that deviates from the plan listed in the effective permit, or (ii) As verification that operations are being conducted in accordance with the plan listed in the effective permit. b. Any survey pursuant to this Paragraph must be performed by a professional land surveyor duly authorized under North Carolina law to conduct such activities. 10. Record keeping Requirements a. The County will record and retain at the facility, or an alternative location near the facility approved by the Division, in an operating record the following information as it becomes available. (i) Inspection records, waste determination records, and training procedures; (ii) Amounts by weight of solid waste received at the landfill to include source of generation.

Following closure of the landfill, the County shall notify the Division that a certification, signed by the project engineer verifying that closure has been completed in accordance with the closure plan, and has been placed in the operating record. The County shall record a notation on the deed to the landfill property and notify the Division of Solid Waste that the notation has been recorded and a copy has been placed in the operating record. The notation on the deed shall in perpetuity notify any potential purchaser of the property that the land has been used as a landfill and its use is restricted under the closure plan approved by the Division of Solid Waste. The County may request permission from the Division to remove the notation from the deed if all waste is removed from the landfill. The County will cap their landfill within 180 days after the final receipt of solid waste. The cap system will consist of 12 inches of intermediate cover, 18 inches of cohesive soil with a permeability no greater than 1.0 x 10-5 cm/sec, and 18 inches of erosive layer. The cap will contain gas venting system consisting of a series of washed stone trenches below the soil liner that will be vented through 10" diameter PVC pipes that penetrate the cap. The cap system will also include the proper seeding and mulching of the erosive layer and other erosion control devices.

Wyoming bentonite or an approved equivalent may be blended with the soil to lower the soil's permeability. (b) A permeability "window" shall be developed for each type of soil from the borrow material that will be used for construction of the cohesive soil cap. The window shall be plotted on a semi -log plot with moisture content versus density. Laboratory testing to develop the window shall include a series of remolded samples compacted to various dry densities and moisture contents utilizing the same compactive effort (ASTM D 698 or D 1557). The remolded samples shall be tested for permeability to determine whether or not the particular soil type will provide the maximum permeability (1.0 x 10-5 cm/sec) at various dry densities and moisture contents. The window is then developed from the accepted remolded samples and moisture contents from the semi -log plot. A straight line is typically drawn between the acceptable points on the moisture -density curve to indicate a range of probable acceptable permeability results. The window will be used in the construction of the test strip to verify the laboratory remolded permeability results. (c) Atterberg Limits (ASTM D4318) and grain size distribution (ASTM D422) and visual classification (ASTM D2488) shall also be conducted on the bulk samples used to prepare the permeability window. These tests can be used as indices on random samples collected from the borrow site during construction to verify the soil type is the same as was used to develop the "window". As a minimum, sufficient visual classifications and Atterberg Limits shall be conducted in association with each permeability test to verify that the construction materials meet specifications. (d) A test strip of compacted cohesive soil cap shall be prepared to verify the permeability "window'' prior to general installation of the cohesive soil cap. The test strip will be used to verify the results from the remolded permeabilities from the borrow site utilizing the permeability window(s) for each soil type that is going to be used for construction of the cohesive soil cap. At a minimum, the verification will consist of three moisture density tests, one Atterberg limits test, one grain size distribution test (ASTM )2488, D4318, and D422), and one Shelby Tube sample for each lift constructed in the test pad. Laboratory permeability tests shall be performed on tube (Shelby or drive tubes) samples of the cohesive soil cap after placement and compaction. The permeability must be a maximum of 1.0 x10- 5cm/sec. Tests shall be performed in accordance with the ASTM D5084. The test strip shall be approximately 2,500 sq. ft. in surface area and constructed to conform geometrically to the site topography with a minimum lateral dimension in any direction of 25 ft. The test strip shall consist of at least three compacted 6 inch lifts of cohesive soil cap. Placement and testing of the test strip shall be in conformance with the construction specifications and requirements for general installation of the cohesive soil cap. Test results from the test strip shall be used to guide placement and achievement of the required maximum permeability of 1.0 x 10-5 cm/sec of the cohesive soil cap. The test strip may be used as an integral part of the overall cohesive soil cap if it meets the required specification for the cap. All results shall be given to the Construction Observer. P:\ Solidwaste\G17041 Lenoir C&D Permit\documents\Permit Application.doc LHC 2/8/2017 1 g (e) The soils shall be placed to the total thickness shown on the plans in maximum 8-inch thick loose lifts with a maximum 6" compacted lift compacted preferably at a moisture content between 0 to 3% above optimum moisture content to 95% standard Proctor maximum dry density (ASTM Test Designation D698). A sheepsfoot roller or approved alternative may be used to compact the soil cap provided the compaction and permeability requirements can be achieved. Each lift shall be tested for permeability, moisture content, particle size distribution analysis, Atterberg limits, moisture -density - permeability relation, and if needed percent bentonite admixed with soil, prior to the placement of the succeeding lift and visually inspected to confirm that all soil clods have been broken and that the surface is sufficiently scarified- so that adequate bonding can be achieved. Soils- for cohesive soil cap shall be screened, disked, or prepared using any other approved method as necessary to obtain a homogeneous cohesive soil with clod sizes in a soil matrix no larger than about 1.5 inches in maximum diameter. After each lift, the surface shall be scarified prior to the placement of the next lift to provide good bonding from one lift to the next. (f) The cohesive soil cap shall be tested to evaluate the coefficient of permeability. The coefficient of permeability of the soil cap shall be equal to or less than 1.0 x 10-5 cm/sec after placement and compaction. The soil cap must be a minimum of 1.5 feet thick. (g) Laboratory permeability tests shall be performed on tube (Shelby or drive tubes) samples of the cohesive soil cap after placement and compaction. The .permeability must be a maximum of 1.0 x 10- 5cm/sec. Tests shall be performed in accordance with ASTM D5084. (h) The soil cap shall be tested a minimum of one soil sample per lift per acre for laboratory permeability. All permeability testing will be on random samples judged by the Engineer to be representative of the most permeable soil conditions for the area being tested. The project engineer shall certify that the materials used in construction were tested according to the Division approved plans. If after placement of the soil cap it fails the required tests, the material will either be reworked or replaced and then retested for permeability. The soil cap must remain moist at all times, if any section becomes dry, rework the dry area and moisten. (i) A minimum of two (2) inches of soil shall be removed prior to securing each sample for permeability testing. The sampling tube shall be advanced vertically into the soil with as little soil disturbance as possible and should be pushed using a uniform pressure. The sampling tube (Shelby tube), when extracted, shall be free of dents, and the ends shall not be distorted. A backhoe or approved alternative should be used to advance the sampling tube (Shelby tube) as long as disturbance is minimized. Drive tube samples of the cap may be obtained for permeability testings. If the Engineer judges the sample to be too disturbed, another sample shall be taken. Once an acceptable sample has been secured and properly prepared, all sample excavations shall be backfilled to grade with a 50% mixture of bentonite and similar soils in maximum 3-inch loose lifts and hand tamped with a blunt tool to achieve a tight seal equivalent to the original density. (j) No additional construction shall proceed on the soil layers at the area being tested until the Engineer has reviewed the results of the tests and judged the desired permeability is being achieved. (k) As a minimum, sufficient visual classifications (ASTM Test Designation D2488) ,analyses (ASTM Test Designation D422) and Atterberg limits (ASTM Test Designation D4318) shall be conducted in association with each permeability test to verify that the construction materials meet specifications. The minimum number of tests will be 1 per lift per acre. (I) If the soil for the cohesive soil cap is incapable of achieving the required permeability when compacted, bentonite or approved alternative may be mixed with the soils to decrease the permeability. The amount of additive required must be determined in the laboratory. Where additives are required, the soil shall be placed in maximum &inch thick loose lifts and compacted, preferably between 0 to +3% optimum moisture content to 95% standard Proctor maximum dry density (ASTM Test Designation )698) for the soil -additive mixture. All other compaction procedures for the soil apply. P:\ Solidwaste\G17041 Lenoir CB:D Permit\documents\Permit Application.doc LHC 2/8/2017 19 (m) The Contractor shall protect the cohesive soil cap from desiccation, flooding and freezing. Protection, if required, may consists of a thin plastic protective cover, (or other material as approved by the engineer) installed over the completed cohesive soil cap until such time as the placement of flexible membrane liner begins. Areas found to have any desiccation cracks or which exhibit swelling, heaving or other similar conditions shall be replaced or reworked by the contractor to remove these defects. (n) The thickness and grade of the soil cap will be verified by the surveyor. The soil cap will be surveyed at 100' grid points where the elevations of the top of landfill will be checked with the top of soil cap to verify 1.5 feet of soil cap. The grade will then be verified with the surveyed information. The survey will be performed by North Carolina Professional Land Surveyor. The soil for the erosive layer shall consist of any soils suitable of supporting vegetative growth. (a) Native vegetation will be used as recommended in the NC Erosion and Sediment Control Planning and Design Manual and as shown in the Closure Plan drawings in Appendix A. (b) The thickness and grade of the erosive layer wi!I be verified by the surveyor. The erosive soil layer will be surveyed at 100 foot grid points where the elevations of the top of landfill will be checked with the top of soil cap to verify 1.5 feet of erosive soil layer. The grade will then be verified with the surveyed information. The survey will be performed by North Carolina Professional Land Surveyor. 4.5 Methane Venting System Gas Venting System NC.D.O.T.

However, any future use of the landfill shall not disturb the integrity of the cap system, base line system or any other components of the containment system or the functioning of the monitoring systems. The County Landfill will be monitored quarterly for evidence of settlement, subsidence and ponding in the cap system. The entire site will be monitored quarterly for evidence and effects of erosion. The erosion control plan will be preserved. All gates, fencing, access roads, and signs shall be maintained appropriately. Annually in the Spring, the vegetative cover will be monitored to assure a good stand of vegetation, and where needed, it will be reseeded. The vegetative cover will be mowed twice a year , once in mid -summer and again in early fall. These maintenance activities will take place over the entire post closure period of thirty years.. The County will make repairs as necessary to maintain the integrity and effectiveness of the Cap System. The County Landfill will monitor and analyze ground and surface water semi-annually for Subtitle D Appendix I constituents for a period of thirty years. The County will also monitor methane gas at landfill structures and the boundary quarterly for the thirty-year period. The County will inspect the exterior slopes of the landfill at least weekly to determine if there are any breakouts of leachate in the slopes. If any are discovered, they will be contained immediately to assure that they will not leave the site. The containment can consist but not be limited to an earthen berm, sand bags, erosion control logs and/or anything that will contain the leachate on the slope. The repair of the breakout will require excavating into the cover soil on the slope down to the waste and into the waste to determine what is causing the leachate to come to the surface. Normally it is another layer of soil that has been used as cover and the leachate is flowing along that layer to the slope and surfacing on the slope. The lower layer of cover needs to be removed at the breakout so that the leachate that is flowing along this cover has a point where it will go vertically into the landfill instead of flowing along the soil boundary that was once either daily cover or an intermediate cover. Once this soil layer has been breached, the excavation can be filed back with stone, clean waste or any material, other than soil, that will allow the leachate to flow vertically instead of horizontally. Once the excavation has been filled with this material, the surface can be cover with soil so that surface water does not intrude into the excavation. Vegetative cover will be reestablished over the excavated area. Following completion of the post -closure care period for each unit, the owner or operator will notify the Division of Solid Waste that a certification, signed by a registered professional engineer, verifying that post -closure care has been completed in accordance with the post -closure plan, has been placed in the operating record. P:\ Solidwaste\G17041 Lenoir C&D Pemut\documents\Permit Application.doc LHC 2/8/2017 25 The largest closed area, to be monitored within the post closure life will be 47 acres.
