November 30, 2016 OPERATIONS & MAINTENANCE MANUAL LANDFILL NO. 6 VERTICAL INCREASE 1.0 GENERAL 1.1 Purpose The purpose of this manual is to provide information to the personnel involved in the operation, maintenance, and closure of the Blue ridge Paper Products Inc., dba Evergreen Products (Evergreen), Canton Landfill Facility (Landfill). Guidelines and procedures for the development and operation of the Landfill are provided herein. It is important to recognize that some of the procedures in this manual may require modification over time in response to new regulations or as improved methods are developed for carrying out the day to day landfill activities. Changes in procedures must be verified with the Canton Mill area management, particularly Environmental, Health and Safety Department (EHS) and Mill Engineering prior to implementation. It is equally important for the personnel involved in landfill operations to understand the critical requirements for successful landfill operation and maintenance. Operation of a landfill is as much about managing water as it is the solid waste. Approximately one million gallons per acre of precipitation falls to the ground in the Canton, North Carolina area on a yearly basis. Management of this and other waters which may be associated with or absorbed by the incoming waste is a principal task of the landfill operations personnel. The Landfill has been designed to collect the precipitation and other water which becomes leachate. It is the operations personnel's goal to insure that maximum leachate collection efficiency is maintained while simultaneously minimizing leachate generation to the extent practical. Minimizing leachate generation is accomplished by separating clean surface runoff from the wastes, encouraging evaporation of leachate, and other procedures which are discussed herein. ____________________ 1-2 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 This manual was prepared with regard to the Solid Waste Rules and Regulations (Regulations) of the North Carolina Department of Environmental Quality (NCDEQ). It includes descriptions of development procedures, landfill operations, site maintenance, safety procedures, monitoring requirements, leachate management, and numerous other important procedures which must be adhered to. Everyone associated with the management and operation of the Landfill should be familiar with this manual to ensure a safe and environmentally secure facility. 1.2 Design Concept It is not the purpose of this document to provide a detailed account of the design of the Landfill; however, a general discussion of the design of the Landfill is presented herein. The Landfill operations personnel are encouraged to review the Design Reports and Engineering Drawings which provide detailed descriptions of the Landfill and its features. The Landfill incorporates an engineered liner system beneath the waste to minimize the potential for leachate to impact the groundwater underlying the site. The current landfill design begins by placing a geosynthetic clay liner (GCL) over the cell base grades followed by a 60-mil thick high-density polyethylene (HDPE) geomembrane. Over the geomembrane is placed a non-woven geotextile followed by a 15-inch granular drainage (leachate collection) layer to collect and transport leachate. Embedded within the drainage layer is a network of perforated pipes to aid in the transport of leachate by gravity flow to a discharge sump or wet well. From the sump, the leachate is pumped to the mill's wastewater treatment plant. Leachate storage ponds are an integral part of the system and provide leachate storage during periods of heavy rainfall. Once an area of the Landfill has reached final waste grades, final cover is applied as detailed in Section 9.0. Final Cover is installed to reduce leachate generation and allow consolidation of the waste. The residual water within the waste will slowly percolate out via the leachate collection system as the waste consolidates. 1.3 Development Concept ____________________ 1-3 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 The Landfill uses natural geographic features in the area such as depressions to maximize the space utilized for the waste stream from the Canton Mill. The main waste streams entering the Landfill are treatment plant sludge, multi-fuel boiler ash and lime from the papermaking process. The engineering properties of these two materials can vary significantly. Traditionally landfill construction consists of building a small self-enclosing berm and installing a liner system inside on which to place waste. To circumvent any issues with the paper mill wastes (i.e., stability) and traditional landfilling techniques, the Landfill enhances and utilizes the depression walls and embankments to buttress the waste to allow the same quantity of waste fill in a similar sized footprint as a typical landfill that would accept municipal solid waste. Development and operation of the Landfill in this manner allows for separation of clean surface water from the waste, thus minimizing leachate generation. The current permit to operate Area D allows placement above the rim (i.e., perimeter dike) of the landfill depressions. Development above the rim typically begins by filling the space below the rim of the depression with waste and then filling above the rim after approval is received from NCDEQ. Figure 1-1 shows the waste grades for Area D South and North, at the end of filling above the rim. Applications to the NCDEQ for successive permit modifications to increase the vertical height of the landfill Areas was made based on successful operation below the rim of each landfill Area.

If the fire does not appear to be controllable with a fire extinguisher, or if the fire is associated with the landfilled wastes, the emergency dispatcher at Mill extension 2911 will be contacted immediately. The emergency dispatcher will be provided with information concerning the location and extent of the fire. 3. The emergency dispatcher will mobilize the appropriate firefighting equipment and personnel. All fire personnel should be notified in advance to alert them of the nature of hazards at the Landfill so they may be appropriately prepared and equipped. 4. All efforts to keep applied water and firefighting chemicals within the landfill limits will be made. 5. EHS department personnel will be notified as soon as possible so that an inspection can be made. 6. Hot ashes on the sludge pile will not be considered a fire hazard unless they are blown by strong winds. 7. EHS department personnel will notify the NCDEQ Division of Solid Waste Management, Solid Waste Section, verbally within 24 hours and a written notification must be made within 15 days of the occurrence. A sample fire occurrence form is shown in Appendix D. ____________________ 2-7 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 2.6 Equipment Requirements The following equipment will be available to conduct the daily landfilling activities, place final cover, minimize erosion, maintain roads, and operate the leachate system: 1. Bulldozer for fine grading; 2. Bulldozer for waste placement and grading; 3. Front-end loader to move cover material and construct temporary berms; 4. Two-way radio communication system. 2.7 Waste Delivery and Acceptance To assure that all information regarding a waste delivery is accurately recorded, it is necessary to adhere to a "flow control" system. The details of the "flow control" system are described in this section and Section 2.8, as well as Section 8.0, which describes in detail the record keeping and reporting requirements which will be followed by this facility. Each day, drivers will provide the following information: 1. The types and sources of the waste being delivered; and 2. The number of truckloads of each type of waste delivered. Each month, drivers will provide the following information: 1. Weights of the trucks according to the established plan. Sample waste receipt forms are shown in Appendix A. Landfill personnel will determine if the Landfill is permitted for the type and source of waste being delivered, see Section 2.8. When the truck arrives at the disposal area, the Landfill Operator will direct the unloading of the waste. Weigh tickets will be obtained periodically from the Scale Operator by Landfill personnel for recording onto the monthly accounting forms. ____________________ 2-8 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 A sample of trucks will be weighed and the gross weight recorded in accordance with Section 8.3. Tare weight will be determined by deducting the truck empty weight determined at the time the truck was acquired from the weight of the truck when it enters the site. 2.8 Waste Inspection Plan The loader operator and truck driver will inspect the waste load and determine if the waste is accepted at the Landfill according to the list of permitted wastes shown below. If there is any question as to the waste being accepted at the Landfill, EHS management will be notified to obtain a decision on whether it is an acceptable waste. The general categories of accepted waste are: 1. Fly ash from multi-fuel boilers; 2. Lime waste (mud); 3. Wastewater treatment plant sludge; 4. Wood waste debris; 5. Cinders; 6. Asbestos containing material (ACM); and 7. Biosolids The Landfill is not permitted to accept the following wastes: 1. Municipal wastes; 2. Hazardous wastes; 3. Radioactive waste materials; 4. Liquid wastes; 5. Non-Evergreen waste; 6. Biomedical waste; 7. Sharps not properly packaged; 8. PCB waste as defined in 40CFR76; and, 9. Wastes banned from disposal in North Carolina by G.S.130A-309.10(F). ____________________ 2-9 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 The Landfill Operator will also inspect each load. If an unpermitted waste is improperly accepted for disposal, the Landfill Operator shall notify EHS management. In the event a special waste is generated, the owner will secure NCDEQ approval prior to disposal. 2.9 Waste Placement and Grading 2.9.1 Waste Placement Plan. The following is the waste placement plan. This plan is designed around the nature of the waste disposed at the Landfill and its location below or above the rim of the active landfill Area. Each lift shall be constructed as detailed herein to achieve the grades shown on the waste grading plans prepared as part of the engineering drawings for each phase. Failure to adhere to the procedures in this Manual could have negative results on overall or local landfill stability. 2.9.1.1 Waste Placement Below the Rim The sludge, woodwaste, and lime mud will be dumped by the haul truck operator and spread by an equipment operator. Dumping of waste will start at the lower elevations within the cell. The Landfill Operator will push and spread the waste over the working face, in layers no greater than 2 feet thick as shown in Figure 2-2. Spreading the waste in thin layers, allows the waste to drain, achieves greater in-place compaction (density), and maintains the stability of the working face. The thin layers of waste will make up waste in lifts approximately 10 to 15 feet thick. Each lift of waste must achieve positive drainage either through proper waste grading or through a mechanical means described in Section 2.9.2 (Special Handling of Waste). ____________________ 2-11 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 Papermill sludge as a byproduct of the papermaking process contains varying amounts of clay that is used as filler. As the sludge is landfilled deeper, the consolidation of the sludge makes the sludge less permeable; water does not drain through it as easily. In order to maintain good drainage within the landfill, the top surface of each lift will be covered with a 12-inch thick drainage layer of granular drainage material, i.e. stone, gravel, etc. In certain locations within the Landfill, the use of a substitute for the stone aggregate as the drainage layer is allowed as described under Leachate Drainage Layers in Section 4.2. The drainage layer will aid in draining the next lift of waste, making for a more stable landfill operation. In addition to the drainage layers, chimney drain strips oriented north to south will be extended upward to the top of the waste lifts, as shown in Figure 2-3. As with the chimney drain strips, the stone drainage layer along the lined sideslopes will also be extended with each new lift of waste. Above the rim this sequence is continued and the final waste surface is covered with a one-foot-thick drainage layer as shown on Figure 2-3. Between Area D South and North; and between Area D North and Area E (proposed) are containment berms that separates the two cells. A drainage layer is also present beneath the waste and will be placed over the final waste surface, prior to filling above the rim or final cover construction, as shown on Figure 2-4. Figures 2-3 and 2-4 are generalized cross-sections and are oriented east to west and north to south, respectively. Special procedures will be implemented during winter operation of the Landfill. Snow and ice removal from operational areas including roads and the working face in the active landfill Area must be maintained to allow proper operation of the Landfill. Waste placement, grading, and site cleanliness become more important during the winter since ungraded frozen sludge or other wet wastes can become a barrier to traffic movement. The access road must be plowed and sanded to provide safe travel conditions. Salt should only be used if necessary, because it may seep into the groundwater and could affect groundwater quality data. Sanding will be the preferred method of road treatment in the winter months. Drainage structures such as culverts should be kept free of ice and snow to assure unrestricted runoff during thawing conditions.

November 30, 2016 Any damage to the liner system of the Landfill that occurs as a result of construction or operational activities will be reported immediately to EHS management for appropriate action. 2.9.1.2 Waste Placement Above the Rim Waste placement above the rim in Area D South and North is allowed, according to the current Permit to Operate. Waste placed above the rim of the landfilled Area does not have the depression wall/embankment to buttress it against movement. Placement of waste above the rim is performed similar to waste placement below the rim with some exceptions. Proper waste placement above the rim is critical to landfill stability. Waste placed above the rim of the landfilled Area will have outside slopes as determined by a stability analysis conducted during the design phase for each cell. Typical outside slopes are likely to range from 3 to 4 feet horizontal to 1 foot vertical. Soft wet wastes must be placed greater than 100 feet away from any outside slope to maximize slope stability. 2.9.2 Special Handling of Waste. Other than asbestos disposal, which is described in Section 2.9.3, certain situations require special landfilling procedures to maintain the integrity of the Landfill and protect the working area and surrounding environment. One special procedure is in areas of the Landfill that have become too wet to work on and the other special procedure is for disposal of boiler ash. Occasionally, wetter than normal waste material will be delivered to the Landfill for disposal. This saturated waste material will not be placed closer than 100 feet from any outside slope. When an area is too wet to work, a mechanism is needed to allow the excess water to drain freely away from the saturated waste area. Drainage and enhanced equipment flotation will be achieved by using a drainage layer that utilizes either a drainage geocomposite, used paper machine wires or used paper machine felts placed over the wet area. This will ensure a channel for excess water to drain from the saturated waste materials while allowing continued waste placement. ____________________ 2-15 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 The safe disposal of boiler ash will protect the working atmosphere and the surrounding environment. Boiler ash amounts to approximately 1,400 cubic yards per week. Two types of ash are brought out to the Landfill: cinders and fly ash. The cinders consist of inorganic boiler residue from the burning of coal and wood fuel. This material is landfilled by spreading it over the working face or it is used as a gravel substitute within the active area of the Landfill. The fly ash is a much finer material and can dry out and become dusty. Landfilling the fly ash can be accomplished by spreading the fly ash and immediately placing a layer of sludge over it or working it into the sludge, depending on the moisture content of the sludge. This will prevent blowing of the ash, and water from the sludge will minimize the generation of fly ash dust. 2.9.3 Asbestos Disposal Procedures. 2.9.3.1 Notification and Approval Procedures A disposal area located between Areas F and H, as shown on Figure 3-1, has been permitted in accordance with 40 CFR Part 61 and 15 NCAC 2D and 10A NCAC 41C to accept asbestos containing materials (ACM). Anyone wishing to dispose of ACM at Landfill No. 6 must contact the EHS Department at 646-2028. The EHS Department will determine that the material to be disposed of is ACM and will issue and coordinate the disposal with the contractor. ACM must be hauled and disposed of by a contractor permitted by the State of North Carolina. The ACM must be removed from the source, transported to the disposal site, and properly buried in compliance with Toxic Substance Control Act and North Carolina Rules. Before approving the ACM disposal, the abatement contractor will assure that any personnel on the transport crew who may be exposed to asbestos fibers above the OSHA permissible exposure limit are required to wear a protective respirator during asbestos unloading and that they have complied the requirements of Evergreen/Blue Ridge Respiratory Protection Program. Personnel or ambient air monitoring may be required during the disposal event. ____________________ 2-16 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 2.9.3.2 Site Security and Maintenance During the unloading of asbestos waste at the Landfill, the Landfill Operator will assure that all personnel and equipment not directly involved with the unloading activity are kept at least 100 feet back from the disposal area. If the driver of the truck that hauled the asbestos has not been trained, he/she will remain in the truck with the windows up, or the driver should remain 100 feet away as per the Rules during a manual unloading process of friable asbestos or during clean-up of asbestos materials. All friable ACM is to be wetted and bagged according to the regulations. Within the disposal area, the bagged ACM is to be placed on an appropriate sized sheet of plastic, and then covered with plastic. Before the end of the day, at least 18 inches of soil will be placed over the plastic covered asbestos waste. The asbestos disposal area at the Landfill shall be permanently identified on a map as an asbestos waste disposal area in compliance with the Regulations. 2.9.3.3 Disposal Procedures Vehicles used to transport ACM must be marked during loading and unloading per 40 CFR 61.149(d)(1)(iii). All trucks must be weighed at the landfill scales on their way in and must reweigh when empty. The weight tickets must be signed by the transporter before departure. All friable or potentially friable asbestos waste will be transported to the disposal area in double 6-mil poly bags, labeled in compliance with 29 CFR 1926.58(k). The transport container shall be leak-tight and labeled in compliance with 40 CFR 61.152. Non-friable asbestos may be transported without bagging if the transport container is poly lined and the material is adequately wetted and covered with 6-mil poly cover and secured to prevent the effects of wind or evaporation on the material during transport. It is the responsibility of Evergreen and their ACM contractor to properly package and label the asbestos waste. The Landfill Operator can reject loads that are not properly packaged and labeled. Non-friable asbestos shall not be shredded, crushed, or subjected to any other form of volume reduction prior to placement in the Landfill. ____________________ 2-17 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 Trucks approaching the asbestos unloading area shall approach as closely as possible before unloading waste. The ACM contractor and Landfill Operator will coordinate asbestos disposal in the designated area shown on Figure 3-1. Waste containers shall be lowered to the ground at the disposal area and not pushed or dropped from the back of a truck. All containers shall be inspected during unloading and any damaged containers shall be immediately wetted sufficiently to prevent dispersal of asbestos fibers during the burying of the waste. The operators can then cover the asbestos with the proper amount of cover material. Damage to containers outside the disposal area may be repaired only by properly trained and licensed personnel under the supervision of the ACM contractor. The amount of asbestos material that may be repacked by the contractor crew is limited to minor asbestos abatement projects in accordance with 10A NCAC 41C.0605. These Rules allow the abatement of disturbances of less than or equal to 35 cubic feet (1 cubic meter), 160 square feet (15 square meters) or 260 linear feet (80 linear meters), of regulated asbestos containing material. If the quantities are greater than the allowed quantities, an asbestos abatement contractor shall be used to clean-up the asbestos release. Workers who must handle or repack damaged bags must wear proper protection equipment, which includes disposable protective clothing, gloves, and respirators equipped with HEPA filters, and must be properly trained and licensed to work with asbestos. All protective clothing and poly lining in the container shall be disposed of in compliance with the asbestos requirements of 29 CFR 1910.1001. 2.9.4 Wet Weather. During very wet weather, access to the working face may become difficult. Grit or gravel can be used to provide a stable traffic mat to improve movement of vehicles on the Landfill as needed, but the amount of these materials should be held to a minimum. ____________________ 3-1 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 3.0 LANDFILL DEVELOPMENT Waste placement within each cell will begin at the lowest elevation and placed as outlined in Section 2.9 in a uniform layer over the entire open operational area. Subsequent lifts will be placed on top of the lower lifts in the same manner until the rim elevation is reached. The initial development of each cell does not permit placement of waste above the rim. Therefore, prior to achieving waste capacity at any given cell, the following cell will be constructed and tied into the current cell as necessary to allow for proper leachate containment, transport, and disposal. Waste placement within that cell will proceed as with the previous cell, beginning at the lowest elevations and buttressing against waste of the previous cell. Upon reaching cell capacity beneath the rim, waste placement above the rim may commence after all necessary permits are acquired. All outer waste sideslopes should be graded as determined by a stability analysis conducted during the design phase for each cell. Typical outside slopes are 3 horizontal to 1 vertical (3H:1V) below the rim and for slopes with toes that are not adjacent to the perimeter dike; and 4H:1V above the rim where the toe is adjacent to the perimeter dike, as shown on Figure 2-3. Waste placement above the rim will continue as in previous cells, maintaining uniform layers over the entire open operational area until final waste grades are achieved, at which point final cover will be placed as outlined in Section 9.0. The current and future landfill development of Landfill No. 6 is shown on Figure 3-1. ____________________ 4-1 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 4.0 LEACHATE MANAGEMENT 4.1 Leachate Generation Leachate will be generated in the landfilled Areas through two mechanisms. Precipitation infiltrating into and running off of the active waste face is the major source of leachate generation at the Landfill. Waste consolidation and subsequent drainage of entrained water is the secondary mechanism by which leachate it generated at the Landfill. Further discussion concerning the volumes of leachate may be found in the Design Reports for Areas D South and North. Leachate is collected and transported through a gridwork of perforated pipes that underlie the waste and drainage layers that are placed along the side slopes of the landfill and between waste lifts. Leachate will flow by gravity to the leachate pump station and storage ponds and is pumped via a force main to the Canton Mill wastewater treatment plant. 4.2 Leachate Drainage Layers Leachate drainage is an important element to the landfill operation. The landfill leachate drainage layers are typically constructed with stone aggregate consistent with gradations of ASTM #57, #67, and #78 stone size. The stone is placed along the bottom and sideslopes of each cell prior to landfill operations. Additional stone is used between each waste lift which drains to the exterior sideslope or to a centrally located chimney drain. The use of stone aggregate is required for the base layer, along the sideslope, and for the chimney drain. The use of stone aggregate or recycled products is allowable for the drainage layers between waste lifts. The recycled products include tire derived aggregate (TDA) and reclaimed concrete aggregate (RCA). A description and handling procedures for the recycled products is described below. ____________________ 4-2 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 4.2.1 Tire-Derived Aggregate. TDA, also known as tire chips, may be substituted for #67 (¾”) stone in select locations of the Landfill. The use of TDA, however, carries several operational and handling changes compared to using stone that are addressed below. TDA will only be used in the leachate drainage layers between the intermediate waste lifts. TDA shall not be used in the construction of chimney drains, in the drainage layer at the base of the landfill Area, or adjacent to any geosynthetic liner or cover material. The drainage characteristics of the TDA are dependent upon the grain size of the material. The grain size specification for the TDA will adhere to ASTM C136-05, Type B (See Appendix E) and the maximum particle size not to exceed three inches. It is important to maintain safe handling and storage of tire chips at the Landfill to minimize the potential of fires. The National Fire Protection Association (NFPA) and Rubber Manufacturers Association recommends tire chip storage piles not exceed 10,000 square feet in area and 10 feet in height. Tire chips will be stored in an area outside of the active cell but within an area that the stormwater drains through the erosion and sedimentation control structures. During active operations of Area D South and North, the TDA can be stored in the footprint of Area E where other landfill materials are stockpiled and stormwater discharges can receive pollutant treatment in the sedimentation pond. This location is preferred over the active waste cell as truck maneuverability can become difficult over non-compacted, i.e. loose, TDA layers. Placement and compaction of TDA requires careful operational practices. Soft sludge areas require the use of a high strength geotextile separation fabric to prevent the migration of waste into the TDA void spaces. In addition, TDA may be tracked into soft waste with a crawler tractor to increase the strength of the waste surface before a geotextile is installed as a new drainage/travel layer. A two-foot layer of TDA is recommended when substituted for one-foot of aggregate stone thickness to maintain the hydraulic conductivity properties comparable to stone after compaction as shown on Figure 2-2. Compaction of TDA should adhere to ASTM specification D6270-08, Standard Practice for Use of Scrap Tires in Civil Engineering Applications (See Appendix E). ____________________ 4-3 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 Periodic inspections of the tire chip storage pile should be performed to maintain the recommended pile size and height. 4.2.2 Reclaimed Concrete Aggregate. RCA may be substituted for #67 (¾”) stone in select locations of the Landfill. Identical to TDA, RCA will only be used in the leachate drainage layer in the intermediate waste lifts and shall not be used in the construction of chimney drains, in the drainage layer at the base of the landfill, or adjacent to any geosynthetic liner or cover material. The grain size specification for the RCA will have a maximum stone size of 6 inches and contain no more than 10 percent fines (i.e., particles smaller than 0.075 mm, or a No. 200 U.S. Standard sieve). Placement and compaction of RCA is similar to stone aggregate. RCA layers shall be placed one-foot thick (as shown on Figure 2-2) and may be tracked into soft sludge areas for added strength before a new drainage/travel layer is installed. RCA compaction shall follow the stone aggregate compaction specifications. RCA storage piles shall be located in the footprint of Area E, with other material storage piles, and stormwater discharges can receive pollutant treatment in the sedimentation pond. 4.3 Leachate Storage The leachate storage ponds utilize a synthetic liner to contain excess leachate. The ponds are designed to store leachate during extended wet weather periods prior to transportation to the WWTP. Typically, the ponds will be dry by design. The capacity of the ponds is approximately 1.7 million gallons. The location of the leachate storage ponds is shown on Figure 3-1. 4.4 Leachate Flow Control The leachate transport piping system between the Landfill and the wastewater treatment plant is designed with gate valves to control the flow if necessary. The following scenarios are described with the proper actions to be taken. ____________________ 4-4 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 The leachate transport system includes a pump station with the capacity to handle up to 200 gpm of leachate flow. If this capacity is exceeded, the leachate flow in excess of 200 gpm will be directed to the leachate storage ponds. There are no actions required by the Landfill Operator for this scenario. Once the flow falls below 200 gpm, the ponds will begin to empty. In the event the leachate transport pipe from the pump station to the treatment plant develops a leak, pipe break, blockage, or the pump station needs maintenance, the transport pipeline can be shut off. A gate valve located on the outlet of the pond can be closed thereby allowing the ponds to fill. Leachate flow will then be temporarily stored in the leachate storage ponds while the problem is solved. 4.5 Leachate Disposal The leachate generated during the operation of the Landfill will be treated by Evergreen's NPDES permitted wastewater treatment facility. ____________________ 5-1 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 5.0 LANDFILL INSPECTION AND MAINTENANCE 5.1 General Landfill inspection and maintenance will be an ongoing activity. All personnel will be expected to observe the condition of Landfill facilities throughout their workday and notify the EHS management of areas and equipment which may need repair and maintenance. Formal landfill inspections will be conducted in the spring and fall of each year. Additional inspections may be warranted following unusual climatic or operational events including, but not limited to, major rain storms, flood, fire, hurricane, or earthquake. These inspections will follow the inspection forms attached in Appendix B. A description of the inspection items are discussed in the remainder of this section. EHS management is ultimately responsible to insure that the inspection and maintenance of all Landfill facilities and equipment occurs. 5.2 Access Roads The access roads to the Landfill will be maintained by Evergreen. Frequent inspections by the Landfill Operators, especially during the spring and winter months will be made to insure that these roads are in safe condition. The summer months are most prone to dry, dusty conditions that can be a nuisance for operators and neighboring properties. Dust control measures are described in Section 5.9 for minimizing dust problems. Internal landfill access roads, including those within the landfill Areas, will be maintained as all- weather roads. Prompt attention to road repairs is the most cost-effective approach since deterioration becomes increasingly more rapid once it has begun. Provisions will be made for snow removal during the winter to maintain relatively normal operations. Waste placement, grading, and site cleanliness become more important during the winter since waste such as ungraded frozen sludge can become a barrier to traffic movement. The access road will be plowed and sanded to provide safe travel conditions. Salt should be used sparingly. Sanding will be the preferred method of road treatment. ____________________ 5-2 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 5.3 Equipment Maintenance of equipment and landfill operations vehicles is critical in controlling and maintaining landfill operations. All equipment will be subject to a comprehensive, preventive maintenance program, as specified in the manufacturer’s specifications. Critical parts or replacement equipment will be identified and obtainable within a short period of time to maintain continuity of operations. 5.4 Erosion Control Facilities Open Areas - Areas outside of the individual landfill Areas, which have been disturbed, will be seeded to prevent erosion. The seeding will be performed in accordance with the seeding schedule contained in the closure plan. Prior to any land disturbing activity greater than 1/2 acre, a soil and erosion plan must be secured by the appropriate mill group (EHS or Mill Engineering). Ditches - Areas, which are riprapped or otherwise protected, will be repaired as necessary. All ditches, which are not riprapped or otherwise protected, will be seeded. All debris and other blockages will be removed from the ditch to allow for unobstructed drainage. Reseeding of the drainage ditches will be necessary from time to time, as erosion occurs. Cover System – It is important that the waste containing Areas of the Landfill that have received final cover remain intact to function to reduce leachate properly. The cover soils will be replaced and the area re-seeded in places where the final cover system has eroded. Repeated erosion in a particular area may require a different cover soil such as riprap as opposed to vegetative soil. 5.5 Leachate Collection Piping A cleanout is located at the end of the leachate collection mains and laterals that extend to the perimeter of each landfill Area. These devices provide a means to remove blockages within the piping system, should they occur. ____________________ 5-3 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 5.6 Leachate Storage Pond To insure the integrity of the leachate storage pond, annual inspections will be made. When the ponds are empty, visual inspection of the liner will be made. Any tears or punctures will be noted and repaired. 5.7 Liner Repair If tears or punctures occur in the liner within the pond or along the sideslopes of the landfill, they will be repaired as soon as possible. Punctures and tears less than 6 inches in length will be repaired by Evergreen personnel if trained personnel are available. Repairs will involve placement of an overlapping patch (6-inch minimum overlap) which will be tack-welded to the underlying liner. Extra liner will be stored on-site for field repairs. If the liner tear is greater than 6 inches in length, a liner installer will be contacted to make the necessary repairs. 5.8 Landfill Underdrain System The landfill underdrain system will be inspected on a monthly basis. An inspection form, see Appendix B, will be filled out to document each inspection. The inspection will consist of the following list. 1. Pipe outlets shall be checked for blockages and that the discharge is not eroding the outlet ditch. Any blockages should be removed to provide free flow from the pipe outlet. If erosion should occur, the ditch outlet should be stabilized, riprapped, or otherwise reinforced. The end of the pipe also has a rodent guard to prevent animals from entering the pipe. This should be checked and repaired, if necessary. 2. Inspect the manholes for blockages or silt build-up. For either case, the EHS management should have the manhole cleaned and reinspected. ____________________ 5-4 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 In addition to a monthly inspection, the underdrains shall be inspected after any major rain storms, floods, fire, hurricane, and earthquake or facility failure. 5.9 Fugitive Dust Control Landfill activities can be a potential source of dust. Dust results from trucks driving over the gravel access roads, blowing of dry waste transported in the trucks, and dust emissions during the landfilling of dry waste. The special handling of dry waste such as fly ash and prevention of dust emissions during landfilling activities is described in Section 2.9.2. The Canton Mill fly ash collection, storage, and loading vessel incorporates a wetting system to raise the moisture content of the fly ash so that it can be transported without dusting. Transport truck beds are covered with tarps to prevent escape of dust from dry waste during hauling. The application of dust control measures on access roads within the Landfill is discussed below. Dust control measures will be implemented at the facility by utilizing water spray trucks to wet roads during dry periods. Additional measures such as applying calcium chloride may be required on an as needed basis. The primary access road to the facility has been paved in order to reduce dust generation. In addition to water, several alternative dust control agents exist for suppressing dust with sand utilized as needed. Some alternatives include natural salt brine solutions as a replacement for calcium chloride; asphalt emulsions; organic, non-bituminous materials; and polymers. ____________________ 6-1 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 6.0 WATER QUALITY MONITORING 6.1 General To aid in evaluating the performance of the Landfill, a groundwater and surface water monitoring program will be conducted. The collection, preparation, preservation, and delivery of the samples to the laboratory shall be the responsibility of the EHS department. A description of the sampling program and procedures is provided in the Environmental Monitoring Plan in Appendix C. ____________________ 7-1 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 7.0 LANDFILL GAS MONITORING 7.1 General To aid in evaluating the performance of the Landfill, a landfill gas monitoring program will be conducted. The collection of landfill gas measurements shall be the responsibility of the EHS department. A description of the sampling locations, frequency and procedures; landfill gas safety procedures; equipment specifications and quality control; and reporting are provided in the Landfill Gas Monitoring Plan in Appendix F. ____________________ 8-1 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 8.0 RECORD KEEPING & REPORTING 8.1 General One of the most important elements of a well-run landfill is an efficient record keeping system. For a facility of this nature, it requires the timely collection, interpretation, and management of large volumes of data. Data collected will be presented in an annual report to the NCDEQ. The annual report will include the source, type, and volume of waste accepted over the course of the calendar year. A copy of the permit and operating plan will be maintained at the facility. 8.2 Operating Records and Annual Reports (a) Evergreen will maintain documentation of all facility operations, including: (1) Identification of the facility, owner, and operator; (2) Quantity, type and source(s) of wastes received; (3) Complete record of inspections, maintenance, repairs, and emergency event response; (4) Data on all environmental monitoring required for the current operating Area(s). (b) Evergreen will file an annual report of operation with the NCDEQ by July 31 of each year, for the previous 12 months of operation. 8.3 Waste Description The Landfill is licensed to dispose of wastes which fall into seven general categories. Regardless of the type of waste, similar accounting procedures will be used. Accounting will include logging the number of truckloads with regard to waste type and volume. ____________________ 8-2 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 The general categories of accepted waste are: 1. Fly ash from multi-fuel boilers; 2. Lime waste (mud); 3. Wastewater treatment plant sludge; 4. Wood waste debris; 5. Cinders; 6. Asbestos containing material (ACM); and 7. Biosolids. The scaled amount of each category of acceptable waste will be recorded on a truckload log sheet. Truck weight samples of each waste category will be logged as needed. A copy of the log sheet is included in Appendix A. ____________________ 9-1 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 9.0 FINAL CLOSURE 9.1 General Closure of the site is a continuing process which includes the following activities: 1. Final waste grading and shaping; 2. Closure of discontinued channels, pipes, or drains; 3. Placement of cover materials; 4. Seeding and fertilizing. The principle goals of the closure plan for the Landfill are: 1) to minimize future generation of leachate; and 2) to provide a cover system suitable for developing a grass crop which will prevent erosion. The final cover system designed for this site will minimize future generation of leachate, and provide a suitable stormwater management plan which will minimize the potential of erosion. Inspection and monitoring of closed areas are necessary to detect erosion and to initiate repair for prevention of significant damage to the landfill cover. Uneven settlement may result in ponding or breaks in the cover system, these areas will be rebuilt and/or regraded to restore proposed contours. In addition, maintenance and post-closure care will include periodic mowing to discourage large, deep-rooted vegetation which can damage the cover integrity. The Owner may permit third-party use of select areas for alternative use; however, State approval must be obtained. One such use is the FLS Energy Solar array located on Area B- Lower which was approved in 2009. Further information is provided in Section 9.8, Alternative Uses. 9.2 Closure Procedures The subsections which follow describe the various closure procedures and activities which must be performed. ____________________ 9-2 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 9.2.1 Grading. The waste will be placed and graded to design final waste elevations. Prior to cover installation, a topographic survey will be performed to insure that the proper grades exist and there are no low areas or depressions within the closure area. The survey will confirm that the slopes do not exceed the proper grades. The survey will also be used to check surface water runoff ditches to insure that proper slopes exist. The waste grades should be kept a minimum of 5 ft (vertical) below the top of the road or 11.5 ft parallel with the slope from the edge of the road, as shown on Figure 9-1. This will allow for a minimum ditch depth of 2 ft. Waste limits are shown on a typical cover section in Figure 9-1. 9.2.2 Drainage Channels, Pipes, or Drains. The closure of leachate collection channels, pipes, or drains will be accomplished in a manner which ensures the integrity of the system for the system's design life. The design life of all components within the Landfill is 50 years; typical products which have this life are stainless steel and high-density polyethylene (HDPE). Design of the closure should also take into consideration the forces acting on the area of interest. Stormwater will be discharge out of Area D via a system of culverts and catch basins. Culverts penetrating the cover system will have concrete headwalls and aprons at the inlet. The stormwater outlets are shown in Figures 9-2 and 9-3. The stormwater runoff from the closed Area D will flow to the south and discharge to the Pigeon River. Modifications will be required to the detention basin at the toe of the South dike of Area D. Stormwater runoff calculations and drawings showing the stormwater routing are presented in Appendix H, Stormwater Management Plan. 9.2.3 Final Cover Systems. Two types of final cover systems over the landfilled Areas have/will be completed; one consists of three layers and the other will consist of five layers. The two types of final cover systems are described below, from top to bottom are: Areas A, B, and C have been covered and consist of the following three layers: ____________________ 9-6 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 1. Four inches of vegetative cover soil; 2. 36 inches of suitable on-site soils, i.e. residual soils; and 3. 12 inches of granular drainage material. Area D will be covered and consist of the following five layers: 1. Four inches of vegetative cover soil; 2. 24 inches of suitable on-site soils, (i.e. residual soils); 3. Drainage Geocomposite; 4. Flexible geomembrane liner; and 5. 12 inches of granular drainage/gas collection material. The 12-inch granular drainage layer will tie into the stone leachate collection and drainage layer along the perimeter of the landfill Areas and will act as a passive gas collection system. The gas collection system will consist of a series of pipes with discharge vents that outlet through the cover system. Permanent markers consisting of metal or fiberglass placards will be placed at the waste boundary of landfilled Areas that have been permanently closed. The markers will extend up approximately 3 to 5 feet above the final cover surface, contain the words “Edge of Waste,” or “EOW,” and have a spacing not to exceed 250 feet. Caution should be taken when installing the sign post so as not to penetrate the liner. 9.2.4 Seeding. All areas which have final cover applied will be seeded. Seeding should normally occur between March 1 and October 15. All surface grading and construction of runoff control structures such as drainage ditches, berms, and culverts are to be performed prior to seeding. The top layer of soil shall be loosened by raking, discing, or other acceptable means before seeding. Lime (2 tons/acre or as needed based on testing) and fertilizer (1,000 lbs/acre of 10/10/10 or as needed based on testing) will be harrowed or disced into the soil at a minimum of 3 inches. If the site is hydroseeded, lime, fertilizer and seed can be applied simultaneously. The seed mixture to be used is as shown below. ____________________ 9-7 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 SEEDING MIXTURE (OR EQUAL) Tall Fescue (KY 31) 80 lb/acre Sericea lespedeza 20 lb/acre Kobe lespedeza 10 lb/acre 110 lb/acre The seed will be applied uniformly with a cyclone seeder, drill, cultipack seeder, or hydroseeder. Seed should not be planted if there is a danger of frost shortly after seed germination. Maximum seeding depth is 1/4 inch when using methods other than hydroseeding. 9.3 Erosion Control The following procedures will be used for erosion control on the seeded areas:  Slopes less than 4:1 - Apply unrotted, long-fibered hay, straw, or cellulose fiber at a rate of 2 tons per acre. Mulch material should be relatively free of all kinds of weeds, and should be anchored with a tractor drawn implement designed to punch and anchor it into the top 2 inches of soil. Anchoring of the mulch will be performed immediately after placement to minimize loss by wind or water. This method of anchoring should be done on the contour wherever possible.  Slopes steeper than 4:1 - On 4:1 slopes or steeper, the seed will be applied by hydroseeding with a binder or excelsior matting to control erosion. Siltation fences will be installed at the bottom of all seeded slopes. Berms will divert runoff from the top of the slopes to established slopes.  Drainage ditches - The grass-bottomed drainage ditches will be seeded in the same manner as the remainder of the site. The same mulch specified above will be placed in these areas. Staples, lightweight biodegradable paper, plastic, or cotton nettings will be placed within the ditches to anchor the mulch. ____________________ 9-8 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 9.4 Long-Term (Post-Closure) Maintenance The subsections which follow describe the various activities which must be performed to insure the long-term integrity of the Landfill subsequent to final closure. 9.4.1 Mowing. To prevent deep-rooted tree growth, the closed portions of the Landfill and drainage ditches will be mowed at least twice per year. Evergreen permits local farmers to use several areas that have final cover applied for hay production provided they cut the area at least 2 times per year to prevent tree growth. 9.4.2 Site Inspection. Once an Area of the Landfill is closed, the Area will be inspected by the EHS in the spring and fall of each year for a period of at least three years to insure the cover system integrity is maintained against differential settlement, erosion and other problems. The inspection will include an examination of the following items:  Surface drainage ways;  Surface grading; and  Grass growth. Each inspection will include notation of any problems and recommended remedial actions. Following the initial three years, an inspection frequency of once per year will be sufficient unless major problems develop, whereupon more frequent inspections will be made. 9.5 Leachate Collection Leachate collection will continue past the closure of the individual Landfill Areas. The primary source of leachate during this period will be consolidation of waste. The amount of leachate which must be collected, transported, and treated will be greatly reduced from that generated during operation of the landfill Area. ____________________ 9-9 2016brpp o&m Sevee & Maher Engineers, Inc. November 30, 2016 9.6 Water Quality Monitoring The semi-annual monitoring program described elsewhere in this manual will continue after site closure. After closure, if the concentrations of parameters analyzed stabilize, the NCDEQ can be approached to reduce the frequency of sampling and the number of parameters analyzed. 9.7 Gas Monitoring Landfill gas shall be monitored in accordance with Section 7.0 and Appendix F until the facility effectively ceases generation of gas. 9.8 Alternative Uses The owner may permit third-party use of select areas of the Landfill for alternative use; however, State approval must be obtained. In such cases, the person or company responsible for the operation and maintenance of the specific site must be made available. Examples of this may include but are not limited to security, fencing, mowing, and maintaining the integrity of the cap. 9.8.1 Solar Array. In 2009, approval was granted for FLS Energy to install and operate a solar array located on the closed portion of the Landfill, Area B-Lower. This area is shown on Figure 3-1.

April 23, 2009 (Revised December 2014) 1-1 1.0 INTRODUCTION This Environmental Monitoring Plan (EMP) summarizes the sampling procedures and analytical methods to be used for groundwater, surface water, underdrain, and leachate monitoring at the Blue Ridge paper Products Inc.’s (BRPP) Landfill No. 6 site in Canton, North Carolina (See Figure 1-1). The procedures, protocols, methods, and monitoring locations in this EMP shall not be changed or altered without approval from the North Carolina Department of Environment and Natural Resources (NCDENR). The purpose of the EMP is to detect any potential impacts of the landfill on the groundwater and surface water in the vicinity of the site. The monitoring wells have been located based on the groundwater flow directions determined from previous hydrogeologic studies at the site. A potentiometric map of the groundwater surface is provided in Appendix C. ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013Evergreen_emp.doc Sevee & Maher Engineers, Inc.

April 23, 2009 (Revised December 2014) 4-1 4.0 SAMPLING PROCEDURES The following sections describe the procedures to be followed for collecting groundwater, surface water, underdrain, and leachate samples at the BRPP site. Sample recordkeeping forms and chain-of-custody forms to be completed for each water quality monitoring location are presented in Appendix A. Monitoring well installation diagrams for the BRPP monitoring wells are presented in Appendix B. 4.1 Groundwater Sample Collection There is typically one of three possible purging and sampling procedures followed for collection of samples from the monitoring well locations at the BRPP site. The specific sampling methods are shown in Subsection 4.1.2, 4.1.3, and 4.1.4. 4.1.1 Well Inspection and Water Level Measurement. Upon arrival at each groundwater sampling location, the sampling personnel will observe the physical condition of the monitoring well(s). The inspection will include observation of the condition of the ground surface seal and the well guard pipe to evaluate if any evidence of frost heaving, cracks, or vandalism are present. The condition of the monitoring well will be recorded on the field data records. Periodically, the area around the well may have to be cleared of weeds, brush, or other materials prior to beginning the water sampling activity. Following inspection of the sampling location, the water level will be measured. The water level in the well casing will be determined by lowering a clean electronic sounding probe into the well until contact with the water surface is made. The distance from the monitoring well reference elevation to the water surface contact will be entered into the field records. Water levels in the monitoring wells will be measured to the nearest 0.01 foot. In all cases, the depth to water will be referenced to the top of the PVC well casing (permanently marked measurement reference point). In instances where water is flowing from the well casing, the water level will be noted as such. Upon removing the water level probe, it will be decontaminated as described in Section 5.0. ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013Evergreen_emp.doc Sevee & Maher Engineers, Inc. April 23, 2009 (Revised December 2014) 4-2 4.1.2 Monitoring Wells Where a Bladder Pump is Used. A submersible bladder pump is used to purge and sample monitoring well locations listed below. The bladder pump is adjusted to remove water from the monitoring well at a rate of approximately 200 millimeters per minute. Field measurements for pH, conductivity, temperature, and turbidity are monitored at five-minute or more intervals until three consecutive field readings are within the field parameter stabilization listed below for approximately 30 minutes prior to sample collection. The use of a bladder pump is applicable at the following wells: MW-13 MW-16S MW-14 MW-18 MW-15 MW-21 MW-16D Field parameter stabilization criteria: pH + 0.1 standard pH unit with respect to previous pH measurement. Specific conductance + 10% of previous measurement. Turbidity + 10% or <10 NTU of previous measurement. Temperature + 1C of previous measurement. 4.1.3 Monitoring Wells Where a Submersible Grundfos Pump is Used. A submersible Grundfos pump is used to purge and sample the monitoring well locations listed below. The Grundfos pump is adjusted to remove water from the monitoring well at a flow rate of between 1.0 and 1.5 gpm. Field measurements for pH, conductivity, temperature, and turbidity are taken every six to ten minutes until three or more well volumes are removed and the field parameters stabilize as discussed in Section 4.1.2. A sample is collected after completing the above purging process. If the water column is drawn down to the pump head, the pump will be turned off and a sample of the recharge water will be collected. The use of a Grundfos pump is applicable at the following locations: MW-10 MW-17 MW-20 ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013Evergreen_emp.doc Sevee & Maher Engineers, Inc. April 23, 2009 (Revised December 2014) 4-3 4.1.4 Monitoring Wells Where a Bailer is Used for Sample Collection. A Teflon bailer is used to purge and sample the monitoring locations listed below. In the case where the well has sufficient recharge, three well volumes of water will be removed from the well prior to sample collection. In the case where the recharge is insufficient and the well water is drawn down significantly, the well will be purged close to dry and a sample of the recharge will be collected. In the case where the monitoring well produces three volumes of water, periodic field measurements of pH, conductivity, temperature, and turbidity will be monitored, and purging will continue until these parameters have stabilized as discussed in Section 4.1.2. The following wells will be sampled using a bailer: MW-1A MW-7A MW-2 MW-8 MW-3A MW-9 MW-4 MW-11 MW-5A MW-12 MW-6 4.2 Surface Water and Underdrain Sampling Procedure Surface water samples from the six surface water locations as well as the one underdrain location listed in Table 2-1 will be collected in the following manner: 1. Collect the sample by immersing the sample bottle or sampling device not more than 1 foot below the water surface. If a stream is being sampled, the sample point will be upstream of the sampler with the opening of the sample bottle or sampling device oriented upstream, but avoiding floating debris. If a culvert is being sampled, the sample bottle or sampling device will be placed where the water flows out of the bottom of the culvert. 2. Directly fill the appropriate sample containers from the sampling device if needed. ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013Evergreen_emp.doc Sevee & Maher Engineers, Inc. April 23, 2009 (Revised December 2014) 4-4 3. If possible, measure the following parameters in the water body:  temperature  pH  specific conductance  turbidity If direct measurement is not possible, these parameters will be measured from water remaining in the sampling device or a separate plastic bottle. This information will be recorded in the sample data record, sample labels will be completed, and the chain-of-custody (COC) procedures will be initiated. 4. Complete the Surface Water or Underdrain Sample Data Record (see Appendix A). 4.3 Leachate Sampling Procedure Leachate samples will be collected from the leachate manhole by either using a Teflon bailer or a glass beaker attached to a pole. After filling sample bottles, pH, conductivity, temperature, and turbidity readings will be taken. The information will be recorded on a Leachate Sample Data Record (see Appendix A), sample labels will be completed, and the COC procedures will be initiated. 4.4 Sample Volume, Preservation, and Holding Times Obtaining required sample volumes, adhering to specified sample preservation procedures and complying with allowable sample holding times are necessary to produce analytical testing results which will be representative of the site water quality conditions. In preparing for each sampling event, the sampling personnel will prepare schedules which will permit adequate laboratory notification and sample delivery to allow testing within the allowable holding times. Preservation of collected samples is accomplished by refrigerating samples at 4 degrees ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013Evergreen_emp.doc Sevee & Maher Engineers, Inc. April 23, 2009 (Revised December 2014) 4-5 Celsius (C) and in some cases by acidification. Physical preservation of the samples will be accomplished by storing the filled sample bottles in covered insulated coolers constructed of impact resistant plastic. Efforts will be made to pack the coolers such that the sample bottles are not subject to movement or breakage. 4.5 Field Instrumentation Calibration Sampling quality control will include the daily calibration of field equipment used to measure pH, turbidity, and specific conductance. ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013Evergreen_emp.doc Sevee & Maher Engineers, Inc. April 23, 2009 (Revised December 2014) 5-1 5.0 EQUIPMENT DECONTAMINATION Decontamination of the sampling equipment and instrumentation is required prior to initiation of sampling and between each sample location to minimize the potential for cross contamination between samples. Clean nitrile or PVC gloves will be worn to reduce contamination potential when performing the decontamination activities, when handling decontaminated sampling equipment, as well as prior to and during all sampling. 5.1 Field Instrumentation Decontamination Field instrumentation, i.e., pH, specific conductance, turbidity, and temperature probes and meters will, under no circumstances, be introduced into a sampling device or sample bottle. To minimize latent influences between sampling locations, the probes and meters will be rinsed with distilled water and, when appropriate, wiped dry with clean paper towels. The electronic water level probe will be introduced into monitoring well(s) prior to the purging process. Upon extraction from a monitoring well, the probe and associated electric lead wire(s) will be cleaned with consecutive rinses of distilled water. 5.2 Bladder Pump and Grundfos Pump Decontamination The Grundfos pumps and bladder pumps used for well purging and sampling, along with the tubing attached to them, will be decontaminated as follows. The bladder pump is cleaned with a solution of soapy water, deionized (DI) water rinse, rinsed with alcohol, and followed by a DI water rinse. Each bladder as well as the pump seals and tubing are replaced between wells. The outside of the Grundfos pump is cleaned in the same manner as the bladder pump. Several gallons of DI water is pumped through the Grundfos pump and all tubing is replaced between samples. ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013Evergreen_emp.doc Sevee & Maher Engineers, Inc. April 23, 2009 (Revised December 2014) 5-2 5.3 Teflon Bailer Decontamination Each Teflon bailer used to purge and sample at monitoring well locations will be cleaned in the Rogers and Callcott Laboratory with a soapy hot water scrub, hot water rinse, alcohol rinse, and DI water rinse. Each bailer will be wrapped with tin foil after decontamination and prior to use. ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013Evergreen_emp.doc Sevee & Maher Engineers, Inc. April 23, 2009 (Revised December 2014) 6-1 6.0 SAMPLE CUSTODY Chain-of-custody (COC) procedures will be followed during sample collection and handling activities during both the field and laboratory operations. The COC procedures assure that each sample is accounted for at all times. To maintain the highest degree of control in sample handling, preprinted labels will be utilized so that all necessary information is retained with the sample. COC records will be used to maintain control over sample access during and after shipment from the sampling location. Additionally, proper completion of field sample logs, accession books, tracking sheets, and extraction logs by appropriate field and laboratory personnel will provide for thorough tracking of the samples from collection through analysis and final reporting. The objectives of sample identification, custody, and tracking procedures are as follows:  All samples collected for analysis are uniquely labeled for identification purposes throughout the analytical process.  Samples are correctly analyzed and results are traceable to field records.  Important sample characteristics are preserved.  Samples are protected from loss, damage, or tampering.  Any alteration of samples (e.g. preservation or damage due to shipment or other processes) is documented.  A record of sample integrity and analytical fate is established. ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013Evergreen_emp.doc Sevee & Maher Engineers, Inc. April 23, 2009 (Revised December 2014) 6-2 6.1 Sample Monitoring Forms The use of standard forms accomplishes one or more of the specific objectives of sample identification, custody, and tracking. Standard forms used by the samplers for water quality monitoring are provided in Appendix A and are discussed below. See attached COC form, field sampling log, and calibration form. 6.1.1 Chain-of-Custody Record. The COC Record is initiated in the field by the individual physically in charge of sample collection. The COC must be completed prior to the shipment of samples to the laboratory. The COC contains information specific to the sample location, date and time of sample collection, the sampler, the project name and number, laboratory project number, the number of containers of each sample being shipped, an itemization of the analyses requested for each sample and any remarks about the sample(s) prior to shipment. The completed COC is signed by the sampler and enclosed with the samples. The COC is then signed each time possession of the samples changes, with the signatures of the persons relinquishing and receiving the samples, as well as the time and date of the sample exchange being indicated on the COC Record. 6.1.2 Sample Collection Forms. The Monitoring Well, Surface Water, Underdrain, and Leachate Sampling Forms will be completed in the field by the individual placed in charge of sample collection. This form correlates the assigned sample bottle designation to a specific well. The forms also list pertinent sampling information that must be recorded at the time of sample collection (i.e., date and time of sampling and field parameter test results). 6.1.3 Instrument Calibration Form. Field instrument calibration procedures will be recorded on the Instrument Calibration Form on a daily basis. ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013Evergreen_emp.doc Sevee & Maher Engineers, Inc. April 23, 2009 (Revised December 2014) 6-3 6.2 Packing and Shipping Samples will be packed and shipped so as to maintain the sample container integrity as well as to provide for the health and safety of the sample transporter. 6.2.1 Packing. Sample containers are generally packed in picnic coolers for shipment. Bottles are to be packed tightly so that no motion is possible. Styrofoam, vermiculite, and bubble-pack are suitable as bottle packing material for most instances. (High-hazard samples may require different packing.) Ice is placed in double Ziploc™ bags and added to the coolers in order to maintain the required 4C preservation requirement. All necessary paperwork will be placed in a separate Ziploc™ bag and also placed in the cooler. The cooler top will then be closed and taped shut. Custody sealing and taping of coolers may be required for certain samples/occasions. 6.2.2 Shipping. The standard procedure followed for shipping environmental samples to the analytical laboratory is: 1. For projects where the laboratory can be practically accessed:  Deliver all samples directly to the laboratory. 2. For projects where the laboratory is not practically accessed: . All shipping of environmental samples must be done through Federal Express or an equivalent overnight delivery service. . If prompt shipping and laboratory receipt of the samples cannot be guaranteed (i.e. Sunday and holidays), the samplers will be responsible for proper storage of the samples until suitable transportation arrangements can be made. ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013Evergreen_emp.doc Sevee & Maher Engineers, Inc. April 23, 2009 (Revised December 2014) 7-1 7.0 QUALITY ASSURANCE/QUALITY CONTROL (QA/QC) Quality assurance/quality control (QA/QC) is an integral part of this EMP to provide for assessment of the adequacy of the analytical results and their intended use. QA/QC activities associated with sampling include utilization of standardized collection procedures and sample data records, calibration of field instruments, and adherence to COC procedures. Analytical QA/QC involves the use of approved analytical protocols by qualified laboratories. Assessment of analytical data quality is performed through review of method-specified quality control data, to be reported along with the analytical results. To ascertain that the QA/QC objectives are met, the following data validation methods will be used to verify the accuracy and precision of the reported results.  Chain of Custody for each sample is continuous and included with report.  Verification that all sample holding times were met.  Identification of values falling outside of historical (>5 sample rounds) range.  Identification of wells whose depths have changed since construction. ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013Evergreen_emp.doc Sevee & Maher Engineers, Inc.

December 18, 2014 1-1 1.0 INTRODUCTION This Landfill Gas Monitoring Plan (LFGMP) summarizes the landfill gas (LFG) procedures used for monitoring at the Blue Ridge Paper Products Inc.’s (BRPP) Landfill No. 6 site in Canton, North Carolina (See Figure 1). Also included in this LFGMP is a discussion of the characteristics of LFG and general safety considerations associated with LFG monitoring. The procedures, protocols, methods, and monitoring locations in this LFGMP shall not be changed or altered without approval from the North Carolina Department of Environment and Natural Resources (NCDENR). 1.1 Landfill Gas Characteristics Landfill gas (LFG) is a mixture of several gases that are produced through anaerobic (oxygen less) decomposition of organic wastes. Typically, LFG is composed of mainly methane and carbon dioxide with smaller amounts of nitrogen and water vapor. LFG is also composed of trace amounts of hydrogen sulfide, other sulfur compounds, and volatile organic compounds (VOCs). Typical components of LFG are shown below in Table 1-1. TABLE 1-1 TYPICAL COMPONENTS OF LANDFILL GAS Component Percent (dry volume basis except moisture) Methane 45 –60 Carbon Dioxide 40 –60 Nitrogen 2 –5 Oxygen 0.1 –1 Hydrogen sulfides, disulfides and other sulfur compounds 0 – 1 Ammonia 0.1 –1 Hydrogen 0 –0.2 Carbon Monoxide 0 –0.2 Moisture 2 –12 Volatile Organic Compounds (VOCs)0.01 –0.6 ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013(Rev 2014)Evergreen_LFG_Monitoring_Plan.doc Sevee & Maher Engineers, Inc. December 18, 2014 1-3 General LFG characteristics which a field technician should be aware of include:  LFG production undergoes changes over the life of the waste placed. Initially air entrained in the waste stimulates aerobic decomposition and produces mainly carbon dioxide. As the oxygen is depleted, large amounts of carbon dioxide are produced with some hydrogen. During complete anaerobic conditions, methane production begins and as the waste ages, the methane, carbon dioxide, and nitrogen production becomes fairly steady.  LFG is primarily composed of methane (typically 50%) and carbon dioxide (typically 45%) both colorless and odorless gases. The odor associated with LFG is due to the lesser and trace gases, such as hydrogen sulfide, that are part of the LFG mixture.  LFG is flammable and potentially explosive. Methane has a flammability range of 5 to 15 percent by volume in air. Five percent being the lower explosive limit (LEL) and 15 percent being the upper explosive limit (UEL). Between these limits, the LFG-air mixture is readily flammable. Just because LFG contains methane above the UEL does not mean that somewhere away from the source the conditions for flammability are not met.  Methane and carbon dioxide have specific gravities of 0.55 and 1.52, respectively. However, the mixture that comprises LFG has a specific gravity closer to that of air (i.e., 1.0); it should not be assumed that LFG will rise.  LFG can migrate within open conduits and through trench backfill or through the vadose zone (unsaturated soil or bedrock above the water table). This migration can allow it to accumulate to flammable or lethal levels in manholes, buildings and other structures designed for human occupancy. This migration through the vadose zone may also cause the LFG to separate into its component gases. LFG migration below the landfill is limited by the presence of a geosynthetic liner system. Landfill gas movement in unlined landfills may be influenced by ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013(Rev 2014)Evergreen_LFG_Monitoring_Plan.doc Sevee & Maher Engineers, Inc.

December 18, 2014 2-1 2.0 LANDFILL GAS MONITORING LOCATIONS AND FREQUENCY During the operation of the facility, gas monitoring will be conducted quarterly at six gas probes and the ambient air of the Landfill House and the Pump Station Motor Control Rooms (see Figure 2). These gas monitoring locations are listed in Table 2-1. The gas monitoring locations have been selected between the waste boundary and the landfill property boundary to monitor the vadose zone for potential LFG intrusion. A typical gas probe diagram and logs of on-site gas probes are provided in Appendix B.

December 18, 2014 3-1 3.0 SAMPLING PROCEDURES The following section describes the procedures to be followed for collecting LFG measurements at the BRPP site. LFG measurement recordkeeping forms to be completed for each monitoring event are presented in Appendix A. 3.1 Landfill Gas Measurement Procedure Upon arrival at each sampling location, the sampling personnel will observe the physical condition of the gas probe. The inspection will include observation of the condition of the ground surface seal and the probe guard pipe to evaluate if any evidence of frost heaving, cracks, or vandalism are present. The condition of the gas probe will be recorded on the recordkeeping form. Periodically, the area around the probe may have to be cleared of weeds, brush, or other materials prior to beginning the water sampling activity. Following inspection of the sampling location, a background set of gas readings will be measured and recorded on the recordkeeping form. The gas probe casing will then be unlocked. The inlet tubing from each meter is attached to the valve on top of the gas probe and the gas readings are recorded. Each meter is detached from the probe and allowed to continue operating at a distance away from the gas probe head until background levels are obtained prior to moving to the next monitoring location. ____________________ \\Nserver\cfs\Brpp\NC\docs\R\2014\2013(Rev 2014)Evergreen_LFG_Monitoring_Plan.doc Sevee & Maher Engineers, Inc.
