Cherokee County will construct a 3.8 acre Municipal Solid Waste Landfill (Phase 2) according to Subtitle D requirements. The facility will be constructed with 24 inches of cohesive soil (permeability of 1.0 x 107 cm/sec), or 18 inches of cohesive soil (permeability of 1.0 x 10'5 cm/sec) with reinforced geosynthetic clay liner (GCL), 60 mil High Density Polyethylene liner (HDPE), 36 inches of protective cover over the liner and a leachate collection system which flows to the leachate lagoon. The_perimater_oi-tbe_Li.n.ed_ar_ea will_be_m.ar_ked_off_b_y_3_in.ch_P_V_C_pi.Re-at190-i.me.rvals_tha.t_wi1Lb-e-pla.cecLi.n the anchor trenches. Solid waste will not be placed within four (4) feet of this boundary to assure that it is being placed directly above the liner system so that no leachate can flow outside of this area. All stormwater that comes in contact with solid waste will be handled as leachate. The leachate is collected in the sump area, where it is pumped by force main to the lagoon. Leachate will be treated at the Town of Andrews Waste Water Treatment Plant. The leachate will have to be tested according to the pretreatment conditions outlined in the pre-treatment agreement. Leachate will be recirculated. (See Appendix IV) The leachate lagoon will be inspected on a monthly basis and a report generated and placed in the landfill records. The report will include the date the liner was inspected, the inspector, general observations since the last inspection, visible abrasions, possible stress cracks, or obvious punctures. Stress cracks can occur in wrinkles that are generated from heat expansion or contraction due to freezing. Also, the HDPE liner may deteriorate due to ultra violet light and this can appear as an abrasion where material can be scraped away with a hard object. If any damage or possible weak spots due to ultra violet exposure has been detected, a qualified HDPE installation company shall be notified immediately so that a repair patch can be installed. The leachate level shall not be allowed to exceed the depth of the damaged liner until it has been repaired and tested by the liner installation company. Once this has been accomplished all testing documentation shall be placed in the operating records. Daily cover will be the combination of soil and synthetic cover. The synthetic cover will be used on days that the next days fill will be placed directly on top of the fill. Soil cover will be used when the next day's waste will not be placed directly on top or the synthetic cover is not large enough to cover the entire area. Soil cover will be placed at least once a week. (See cover requirements under operational requirements). The County will implement a program at the landfill for detecting and preventing the disposal of hazardous and liquid wastes. 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. (See Section 5.3-Appendix 1). The County of Cherokee will monitor for explosive gases at landfill structures and the perimeter of the landfill. 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. (See Section 5.5-Appendix III) 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: Immediately take all necessary steps to ensure protection of human health, i.e. no smoking, temporarily abandon the structure and notify the Division of Solid Waste Management. 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 P \solid waste\Cherokee PTC Ph. Nocumcnts\G02032-111-C Ich Rev 812010.3 109 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 of Solid Waste management that the plan has been implemented. The plan will describe the nature and extent of the problem and the proposed remedy. Off 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. Tine-County_o#SChemLea--wjll_m-d-and_r_etai- at the landfill an Q ratin 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) Waste determination, Leachate sampling data, leachate levels, meteorological data ; (4) Gas monitoring results and any remediation plans; (5) Any demonstration, certification, findings, monitoring, testing or analytical data required for surface and groundwater monitoring; (6) Any monitoring, testing or analytical data required for closure or post -closure; (7) Any cost estimates and financial assurance documentation. All information contained in the operating record will be furnished upon request to the Division of Solid Waste Management or be made available at all reasonable times for inspection by the Division. Ground and surface water will be sampled and analyzed according to Subtitle D Appendix I detection monitoring requirements. The monitoring frequency for all Appendix I(Section 5.3) 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 of Cherokee 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 of Solid Waste. 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.

At the end of every day, waste will be covered either by synthetic cover or 6" of soil cover. At a minimum soil will be used once a week. Any waste that requires immediate cover, will be covered immediately with soil. b. "Disease vectors" means any rodents, flies, mosquitoes, or other animals, including insects, capable of transmitting disease to humans. 4. Explosive gases control a. Cherokee County must ensure that: i. The concentration of methane gas generated by the landfill does not exceed 25 percent of the lower explosive limit for methane in landfill structures (excluding gas control or recovery system components); and ii. The concentration of methane gas does not exceed 100 percent of the lower explosive limit for methane at the landfill property boundary. b. Cherokee County will implement a routine methane monitoring program to ensure that the standards of 4 (a) are met.

P:\solid wade\Cherokee P'I'C Ph. 2\doc moms\G02032-PTC Ich Rev. 8120/0 i 114 9 Liquids Restriction a. Bulk or non -containerized liquid waste will not be placed in the landfill unless: (i) The waste is household waste other than septic waste and waste oil, (ii) The waste is leachate or gas condensate derived from the landfill. b. Containers holding liquid wastes will not be placed in the landfill unless: (i) The container is a small container similar in size to that normally found in household waste; (ii) The container is designed to hold liquids for use other than storage; or (iii) The waste is household waste. C. For the purpose of this paragraph: (i) Liquid waste means any waste material that is determined to contain "free liquids" as defined by Method 9095 (Paint Filter Liquids Test), S. W. 846. d. Test for free liquids: Sludges or other wastes may be tested for free liquids after previous screening tests have shown that the waste is not hazardous and does not contain PCB's. The specified test to determine whether or not a material is considered to be a liquid is the Paint Filter Test method 9095. The procedure for conducting this test is as follows: (i) Obtain standard 400- micron paint filter; (ii) Place a properly -sized, clean, dry funnel in a ring stand or similar device; (iii) Fold the filter and line the funnel with it; (iv) Place a 100 ml sample of waste into the funnel; (v) Place a clean, dry container under the funnel; and, (vi) Check in exactly 5 minutes to see if any liquid is in the container. (vii) If any liquid passes through the filter in 5 minutes or less, the waste is considered to be a liquid. The filtrate can be water, oil or any combination of any non -hazardous liquids. 10. Record keeping Requirements a. Cherokee County MSWLF will record and retain at the facility, or an alternative location near the facility approved by the Division of Solid Waste Management, 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. P\solid waste\Cherokee PTC Ph. 2\documents\G02032-PTC Ich Rev. 8 ORI, 1 1 j (iii) Waste determination, Leachate sampling data, leachate levels, meteorological data ; (iv) Gas monitoring results and any remediation plans; (v) Any demonstration, certification, findings, monitoring, testing or analytical data required for surface and groundwater monitoring; (vi) Any monitoring, testing or analytical data required for closure or post -closure; and, Ancostcost estimates and financial assurance documentation. All information contained in the operating record will be furnished upon request to the Division of Solid Waste Management or be made available at all reasonable times for inspection by the Division. Cherokee County will maintain a copy of the operation plan at the landfill. 11. Spreading and Compacting Requirements The initial lift of solid waste will be placed over Phase 2. This lift will be covered with six (6) inches of daily cover. This lift will absorb the rain water and allow some of it to evaporate prior to reaching the leachate collection system. When a heavy rain does occur, the impact on the leachate collection system will not be immediate. Prior to placement of solid waste over any leachate pipe, the geotextile fabric that is covering the stone will be folded back so that solid waste will be in direct contact with the stone. This method will not allow biological growth to develop on the geotextile which could eventually clog the system. b. The initial lift of solid waste will be placed loosely at a depth of 4 feet. As this lift is being placed, a spotter should be placed in the landfill to assure that the compactor does not drive any long, sharp objects through the protective cover into the liner system. If an object were to penetrate the liner system, the protective cover must be removed and the penetration repaired. The subsequent lifts can be placed up to final grades. Heavy landfill equipment including articulating dump trucks, and compactor will only be allowed on areas that have a minimum of 4' of solid waste. Only low pressure equipment such as a D6 LGP Caterpillar will be allowed on the protective cover. C. The landfill will restrict solid waste into the smallest area feasible, typically 60' x 75' area Solid waste will be compacted as densely as practical into cells. The compactor should run over an area of solid waste a minimum of 6 times. Appropriate methods such as fencing and diking will be provided within the area to confine solid waste subject to be blown by the wind. At the conclusion of each day of operation, all windblown material resulting from the operation will be collected and returned to the area. 12. Leachate Management Plan a. Cherokee County will periodically maintain the leachate collection system. b. Cherokee County will maintain records for the amount of leachate collected. C. Cherokee County will quality sample their leachate bi-annually for Appendix I (Section 5.3) constituents, pH, BOD, COD, TDS, phosphate, nitrate, and sulfate. The sample will be obtained from the lagoon and sampled the same time as the monitoring wells. d. The leachate is being treated by the Town of Andrews Waste Water Treatment Plant. Paolid wasteTI-okee FTC Ph 2\docomems\G02032-11 C Ich Rev. 8/20/0.1 1 ] 6 Under extreme operational conditions Cherokee County has the option of shutting down the flow of leachate to the lagoon by shutting off the pump. The leachate will be temporarily stored within the MSWLF units until such a time the flow of leachate can continue to the lagoon. If any rain or other event requires storage of leachate or storm water in the cell, the Division of Solid Waste will be notified immediately followed by written communication. Leachate will be recirculated. (See Section 5.6-Appendix IV) P:kolid waste\Cherokee PTC Ph. Zdocuments\G02032-11 C Ich Rev, 8C0/03 1 ] 7 5.3 Appendix I A. INTRODUCTION The municipal solid waste stream is made up of wastes from all sectors of society. The waste is often categorized by its source or its characteristics. Terms used include commercial, industrial, residential, biomedical, hazardous, household, solid, liquid, demolition/construction, sludge, etc. Regardless of how one classifies wastes, the bottom line is that wastes are delivered to the landfill and a management decision must be made to either reject or accept them. This responsibility rests with the manager of the landfill. Wastes which are not authorized to be accepted at the landfill create a number of potential problems including: (1) liability due to future releases of contaminants; (2) bad publicity if media learns of unacceptable waste entering the landfill; (3) potential for worker injury; (4) exposure to civil or criminal penalties; (5) damage to landfill environmental control systems. B. HAZARDOUS WASTE REGULATIONS AND MANAGEMENT In the United States, hazardous waste is regulated under RCRA, Subtitle C. A waste is hazardous if it is listed as a hazardous waste by the Administrator of the Environmental Protection Agency (EPA) in the Code of Federal Regulations, Title 40, Part 261, or if it meets one or more of the hazardous waste criteria as defined by EPA. These criteria are: • Ignitability • Corrosivity • Reactivity • Toxicity Ignitability Ignitable waste is a waste that burns readily, causes a fire by friction under normal circumstances, or is an oxidizer. Any waste having a flash point of <140F falls in this category. Flash point is that temperature at which a liquid gives off vapors that will ignite when an open flame is applied. Under Department of Transportation (DOT) definitions, a flammable liquid has a flash point of >100 F. A combustible liquid has a flash point between 100 and 200 F. Therefore, a flammable liquid is always hazardous while a combustible liquid may or may not be hazardous depending upon its flash point. Corrosivity A corrosive waste is one having a very high or a very low pH. The pH of a liquid is a measure of how acidic or basic (alkaline) the material is. The pH scale ranges from 0 to 14. High numbers are basic and low numbers are acidic. A substance having a pH <2.0 or >12.5 is defined as hazardous under RCRA. Reactivity A waste is reactive if it is normally unstable: reacts violently with water; forms an explosive mixture with water; contains quantities of cyanide or sulfur that could be released to the air; or can easily be detonated or exploded. These wastes may fall into any one of several DOT categories. Toxicity Characteristic Leaching Procedure (TCLP) A waste is TCLP toxic if the concentration of any constituent in Table 1 exceeds the standard assigned to that substance. The TCLP is a methodology which attempts to simulate the conditions within a landfill. An acidic solution is passed through a sample of waste and the resultant "leachate" is analyzed for contaminants. The TCLP is designed to detect heavy metals, pesticides and a few other organic and inorganic compounds. The purpose of the test is to prevent groundwater P\solid waste\Cherokee PTC Ph Mocuments\G02032-11 C Ich Rea, 8'20.'0.1 1 1 8 contamination by highly toxic materials. TCLP tests the mobility of 40 different elements and compounds. Except in certain specified circumstances, regulated quantities of hazardous waste must be disposed of at a permitted hazardous waste disposal facility. In accordance with 40 CFR Part 261.3, any material contaminated by a hazardous waste is also deemed to be a hazardous waste and must be managed as such. Hazardous waste from conditionally exempt small quantity generators are to be disposed of in a Hazardous waste disposal facility. RCRA permits are also required to store, transport, and treat hazardous waste. C. POLYCHLORINATED BIPHENYL'S (PCBs) Introduction PCBs are nonflammable and conduct heat without conducting electricity. These compounds were most frequently used as an additive to oil or other liquids in situations where heat was involved. The PCBs enhance the heat conducting properties of the liquid and thereby increase the heat dissipation or cooling effect obtained. They have also been used in lubricants and paint. In the United States one of the most common applications was in electric transformers. The only effective method for destroying PCBs is high Temperature incineration which is relatively expensive due to a shortage of PCB incineration capacity.

There are many millions of pounds of PCBs still in use or in storage. One example is the ballasts used in fluorescent light fixtures. It has been estimated that there are between 0.5 million and 1.5 billion ballasts currently in use in this country. Due to the long life of these units, about half of these may be of pre-1979 manufacture and contain PCBs. Since each ballast contains about one ounce of nearly pure PCB fluid, there are about 20 to 30 million pounds of PCBs in existing lighting fixtures. These items are not the subject to RCRA Subtitle D Waste Screening! Commercial or industrial sources of PCB wastes that should be addressed by the program include: • Mineral oil and dielectric fluids containing PCBs; • Contaminated soil, dredged material, sewage sludge, rags, and other debris from a release of PCBs; • Transformers and other electrical equipment containing dielectric fluids; and • Hydraulic machines. 2. PCB Regulatory Requirements As contrasted to hazardous wastes, the Toxic Substance Control Act regulates PCBs based on the concentration of PCBs in the waste rather than the source or characteristic of the waste. The regulations concerning PCB disposal are spelled out in 40 CFR Part 761. Subtitle D of RCRA merely requires that PCB waste not be disposed in a MSW landfill. PCB management requirements include: Waste containing more than 500 ppm of PCBs must be incinerated. Waste containing from 50 to 500 ppm must be disposed of by incineration, approved burning, or in chemical waste landfill permitted to receive such wastes. The regulations are silent concerning wastes containing less than 50 ppm of PCBs; however, the regulations cannot be circumvented by diluting stronger wastes. D. FUNDAMENTALS OF WASTE SCREENING Know Your Generators and Haulers Since the level of sophistication of your waste screening program will be a reflection of the likelihood of hazardous waste and PCB waste being in your incoming waste, knowledge of the commercial industrial base of your service area is critical. Some examples are the automotive industry, which generates solvents, paint wastes, lead acid batteries, grease and oil; the dry cleaning industry, which may generate filters containing dry cleaning solvents; metal platers which generate heavy metal wastes; and other industries which generate a variety of undesirable wastes; e.g. chemical and related products, petroleum refining, primary metals, electrical and electronic machinery, etc. Landfill managers should also know the haulers and trucks serving the businesses in their community which are likely to carry unacceptable wastes. Some local governments and solid waste management agencies have enacted legislation requiring haulers to provide a manifest showing the customers whose wastes make up that particular load. Such a manifest is an extremely useful tool when a load is found to contain prohibited wastes. It is unwise to accept wastes from unknown, unlicensed, or otherwise questionable haulers. Inspections An inspection is typically a visual observation of the incoming waste loads by an individual who is trained to identify regulated hazardous or PCB wastes that would not be acceptable for disposal at the MSWLF unit. The training of landfill personnel will be conducted by a local EMS official or a P.\solid waste\Cheroi:ee PTC Ph. 2\documents\G02032-PTC Ich Rcc8/20/03 1 2 1 SWANA certification. An inspection is considered satisfactory if the inspector knows the nature of all materials received in the load and is able to discern whether the materials are potentially regulated hazardous wastes or PCB wastes. Ideally, all loads should be screened; however, it is generally not practical to inspect in detail all incoming loads. Random inspections, therefore, can be used to provide a reasonable means to adequately control the receipt of inappropriate wastes. Random inspections are simply inspections made on less than every load. At a minimum the inspection frequency will not be less than one percent of the waste stream. The frequency of random inspections may be based on the type and quantity of wastes received daily, and the accuracy and confidence desired in conclusions drawn from inspection observations. Because statistical parameters are not provided in the regulation, a reasoned, knowledge -based approach may be taken. A random inspection program may take many forms such as inspecting every incoming load one day out of every month or inspecting one or more loads from transporters of wastes of unidentifiable nature each day. If these inspections indicate that unauthorized wastes are being brought to the MSWLF site, the random inspection program should be modified to increase the frequency of inspections. Inspection priority also can be given to haulers with unknown service areas, to loads brought to the facility in vehicles not typically used for disposal of municipal solid waste, and to loads transported by previous would-be offenders. For wastes of unidentifiable nature received from sources other than households (e.g., industrial or commercial establishments), the inspector should question the transporter about the source/composition of the materials. Loads will be inspected on the tipping floor at the baler facility prior to actual disposal of the waste at the working face of the landfill unit to provide the County the opportunity to refuse or accept the wastes. An inspection flow chart to identify, accept, or refuse solid waste is provided as Figure 1 Inspections of materials may be accomplished by discharging the vehicle load in an area designed to contain potentially hazardous wastes that may arrive at the facility. The waste should be carefully spread for observation using a front end loader or other piece of equipment. The Division of Solid Waste recommends that waste should be hand raked to spread the load. Personnel should be trained to identify suspicious wastes. Some indications of suspicious wastes are: • Hazardous placards or markings; • Liquids; • Powders or dusts; • Sludges; • Bright or unusual colors; • Drums or commercial size containers; or • Chemical odors. Cherokee County will follow these procedures when suspicious wastes are discovered. • Segregate the wastes; • Question the driver; • Review the manifest (if applicable); • Contact possible source; • Call the State Solid Waste Management Department; • Use appropriate protective equipment; • Contact laboratory support if required; and • Notify the local Hazardous Material Response Team. Pasolid aasteWherokee PTC Ph. 2Vlocumen[s\G02032-P"hC lei, Rev. S120l01 122 Containers with contents that are not easily identifiable, such as unmarked 55-gallon drums, should be opened only by properly trained personnel. Because these drums could contain hazardous waste, they should be refused whenever possible. Upon verifying that the solid waste is acceptable, it may then be transferred to the working face for disposal. Testing typically would include the Toxicity Characteristic Leaching Procedure (TCLP) and other tests for characteristics of hazardous wastes including corrositivity, ignitability, and reactivity. Wastes that are suspected of being hazardous should be handled and stored as a hazardous waste until a determination is made. If the wastes temporarily stored at the site are determined to be hazardous, Cherokee County is responsible for the management of the waste. If the wastes are to be transported from the facility, the waste must be: (1) stored at the MSWLF facility in accordance with requirements of a hazardous waste generator, (2) manifested, (3) transported by a licensed Treatment, Storage, or Disposal (TSD) facility for disposal. E. RECORD KEEPING AND NOTIFICATION REQUIREMENTS Records must be kept pursuant to an incident where regulated hazardous waste or prohibited waste is found at the landfill. It is also recommended that records be kept of all screening activities and incidents, whether or not, regulated or prohibited wastes are found. This will help prove that the landfill owner/operator has acted in a prudent and reasonable manner. The best way to prove compliance with this requirement is to document each inspection including: Date and time of waste detection Hauler name (company and driver) Waste(s) detected Waste generator(s) if able to identify Action(s) taken to manage or return material(s) Efforts taken if extreme toxicity or hazard was discovered Landfill employee in responsible charge 40 CFR Part 258 requires that records should be maintained at or near the landfill site during its active life and as long after as may be required by the appropriate state or local regulations.

Be sure to allow for five to ten feet extra on each measurement to ensure that the refuse is completely covered. 2. The synthetic cover is shipped to the landfill site with panels folded accordion -type, then rolled up. Unroll the cover along the working face (depending upon operations), and attach the leading edge of th.e�nrolle.d_panel_tn_exis-tinglan-dfi.l.l_e.q_u.i.pm.e.nt with_r_op_e.s.(i.a.--to-the t -thP h Pull the sewn panels of cover across the compacted trash. The synthetic cover maybe pulled from any direction, which may vary from day to day. Keep the leading edge between the two machines (or people) as high as possible to eliminate drag. . 4. Anchor the edges of synthetic cover every 20 feet with tires or sandbags to hold the synthetic cover in place. If it is windy, more anchoring may be required. Make sure a large enough panel has been ordered to completely cover the refuse (base this on the heaviest day. to the week). If complete coverage is not possible, cover the exposed refuse with soil; but take care not to place too much dirt on the synthetic cover if it is to be re -used. 5. On the next day of operations, remove the tires and/or sandbags. Simply pull the synthetic cover across itself (to reduce drag) and off the refuse to an area that is inactive. Anchor the edges again to prevent wind from lifting the blanket. At the end of the day, pull the synthetic cover back across the refuse by repeating steps 3 and 4 until a new panel is needed. Synthetic Cover is designed to be used as landfill daily cover on a working face. For best results, it is recommended that the area to be covered be kept as close to a square shape as possible not to exceed 75' X 75' in size. Not only does this procedure allow for easier coverage, it allows for better management of the working face and saves time at the end of the working day. Cherokee County will use a panel of synthetic cover that is pulled over the working face on a daily basis by two pieces of landfill equipment. At the end of the working day, the panel will be secured in place. This is attained by one of two methods : the panel may be heavy enough to hold itself in place due to accumulation Of soil and is left in that manner; or tires are placed on the panel to secure it in place. The working face is operated in this manner, brought to an intermediate grade and then covered with the required six (6) inches of soil. The process will continue until a lift is completed. The process is then started over on the next lift until the landfill is filled to final grade and a section is closed. At a minimum six (6) inches of soil cover will be used once a week. TIPS TO REMEMBER Always pull the fabric across itself during installation and removal to make each panel last as long as possible. Avoid driving on the panel(s); this may cause punctures and tears. Tie the panel(s) to the top of the dozer blade and raise the blade to minimize dragging on refuse. Use tires or sandbags to hold the panel(s) down overnight. Soil can be used if you plan to leave panel(s) in place and cover with refuse. 5. Minimize stress between dozer/compactors while pulling on the panel(s). P:\solid waste\CheroAee VTC Ph. 2\documen1s\G02032-P'ITC Ich Rev. 8/20/03 127 5.5 Appendix III EXPLOSIVE GAS CONTROL PLAN FOR - CHEROKEE COUNTY Quarterly the Cherokee County landfill will monitor the explosive gas at the landfill structures and at or near the landfill boundary. The permanent probes will consist of a plastic stand pipe similar to a piezometer used for groundwater detection. A typical permanent methane probe is detailed in the operation drawings. The permanent probe will be constructed at a depth of six (6) feet. A 6" diameter hole will contain a one (1) inch slotted PVC pipe. The bottom two (2) feet will be backfilled with non -carbonate pea gravel with a bentonite seal one (1) foot thick above it. The remaining three (3) feet will be backfilled with in situ soils. The one (1) inch PVC pipe will be approximately three (3) feet above the existing grade. The PVC pipe will be capped with a one (1) inch PVC cap, one quarter (1/4) inch NPT hose barb, and 1" tubing, plugged or capped. The location and spacing of the methane monitoring probes is somewhat arbitrary. The locations were determined by the relationship of solid waste with property lines and landfill structures. The spacing of the monitoring probes is between 200 and 400 feet. The migration of methane gas is induced by pressure gradients. The methane will move from areas of high pressure to those of low pressure following the path of least resistance. The methane will migrate vertically until it reaches the landfill cap, where it will begin to flow horizontally. This occurs until it finds a pathway out, either by the installed methane collection trenches or migration through the permeable in situ soils. Since methane is lighter than air, it wants to escape into the atmosphere. It has been our experience that whenever gas is migrating no matter what the spacing or depth of the monitoring probes, the gas will fill the void created by the monitoring point and an explosive meter will monitor the level. The six foot depth of the monitoring probes is to ensure a stable monitoring point. The only time a shallow monitoring point has not worked is in a very heavy, impermeable clay layer that acts as a seal to the migration of the gas. If a clay layer is encountered during the construction of the monitoring points, it will either be moved beyond the clay or excavated to a depth that is in the conductive zone below the clay. The permanent probes will surround Phase 2. Cherokee County's landfill is designed with a base liner system and cap system, there should be no migration of methane in the permeable in situ soils. The gas can be detected by use of an instrument that reports the percent of lower explosive limit. The instrument being used is the Gas Tech GP 204. Quarterly, a County employee will visit each monitoring point either the temporary or permanent. The monitoring points consist of all methane probes and leachate collection system cleanouts. Using the detection instrument, he will determine if methane gas has filled the probes. If the probe is near the property line and methane gas is detected at or beyond the lower explosive limit (100% LEL), it must then be determined if the gas is migrating across the landfill boundary. If the probe is on the boundary or methane gas has migrated beyond the boundary , a remediation plan must be completed by Cherokee County. Other points of monitoring will be the landfill structures. Each structure will be monitored for methane using the following methods: 1. All crawl spaces will be monitored; 2. All corners in the structure will be monitored; 3. Any holes, cracks and pipes through the foundation will be monitored If methane gas is detected beyond 25% of its lower explosive limit in any structure, check the calibration of the monitor and resample. If the reading is still above 25%, evacuate the building and try to find the source of gas. If the source is found try to remove the source. If this fails a remediation plan is stated in the operational requirements. VAsolid waste\Cherokee PTC Ph. 2\documents\G0203_'-P'rC u, Ike,. 8/20103 128 5.6 Appendix IV CHEROKEE COUNTY'S RECIRCULATION PLAN Cherokee County does intend to utilize recirculation as a means of disposal of their leachate. The intention is to utilize recirculation as a method by which some relief can be given to the pumping and hauling. This relief will come in the form of evaporation and retention of water within the solid waste. The remaining leachate will be hauled to the Town of Andrews Waste Water Treatment Plant for disposal. Cherokee County must obtain a permit from the Division of Solid Waste before leachate recirculation can begin. No water that comes in contact with the present surface of solid waste runs off any where other than the leachate collection system. The County will spread the leachate over the surface of the solid waste, that is at a minimum five feet (5') deep, within the landfill. The spreading will be accomplished by one of two methods. The first method is by simply backing their leachate hauling truck into the landfill. A spreader hose will then be attached to the leachate tank and Cherokee County personnel will manually discharge the leachate over the solid waste. The second method will utilize the tank truck except the leachate will be used to wet down solid waste that is piled up from being dumped from a truck or trucks. Once this pile is wet, it will be spread around the working face by the trash compactor. At a later date, a pump system may be incorporated into the system. The pump system will pump directly from the leachate lagoon and the leachate spread in a manner as it was from the tank truck. Monthly monitoring will be performed to measure the leachate head at the leachate head detection well and analyze the leachate for BOD, COD, temperature and pH. The following conditions will be met by Cherokee County: • A rain gauge and thermometer will be placed on site • A base line sampling of leachate has been performed (See Attachment 1) • A brief description of the equipment and its associated specifications is submitted (see Attachment 2) • Weekly record of leachate head measurements (see Attachment 3) • Weekly record of leachate recirculated and leachate disposed (see Attachment 4) • Weekly record of visual monitoring log (see Attachment 5) • Weekly record of rainfall and lagoon depth (see Attachment 6) • Records will be kept on a weekly basis • No leachate will be applied on less than one lift (8 feet) of waste • No leachate will be recirculated when it is raining, or when the waste is too wet • No run off or side seepage will be allowed • Odors will be controlled • Leachate depth will be monitored in the leachate head detection well to ensure that the head on the liner does not exceed one foot for more than 24 hours. • The application system will be properly maintained and documented • Leachate will be tested every 30 days and a progress report will be submitted annually 1) \solid waste\Cherokee PTC Ph. 2\d0cuments\G020.12-PTC Ich Rec. 8/20/03 129 ATTACHMENT 1 BASELINE DATA TO BE ADDED IN THE FUTURE 1)isolid wasleTherokec PTC Ph. 2\docomcros%G02032•PTC Ich Res 3/20/03 - 130 U 11 \solid waste\Cherokee PTC Ph. 2\documents\G020,2-PTC Ich Rev. 912010; 1 J 1 ATTACHMENT CHEROKEE COUNTY LEACHATE HEAD READINGS DATE DEPTH AT HEAD TEST WELL P.\solid svaste\Cherokee P fC Ph. 2\ducumems\G02032-P'fC Ich Am 8/20/03 132 ATTACHMENT 4 CHEROKEE COUNTY LEACHATE RECIRCULATION DATA VOLUME HAULED DATE VOLUME RECIRCULATION ' 'FOR DISPOSAL RECIRCULATED AREA (Se_ctinn_of Landfill) P:\solid waste\Chcrokcc PTC Ph 2tdocumcros\G02032-P1'C Ich Rev, 812010' 133 ATTACHMENT 5 CHEROKEE COUNTY VISUAL MONITORING LOG DATE MONI DUAL TIOR NG I OBSERVATIONS P:uolid waste\Cherokee PTC Ph. 2\d0cuments\G02032-PTC Ich Rev.

In January of 1998, Phase 1 was permitted to operate for 5 years. The permit to construct was issued for approximately 7 acres; however, approximately 5.5 acres were constructed because it was determined that the adjoining counties were not going to dispose of their waste in the Cherokee County Landfill. According to a survey that was completed in November of 2002, there is 1.9 years of life remaining in Phase 1 as it was constructed. We are presently working on a Permit revision for authorization to Construct Phase 2. Once permission is granted, the County will construct the remainder of Phase 1 and Phase 2. We expect to submit the permit to construct Phase 2 within two months; however, in the meantime, the County is requesting permission to continue to operate Phase 1 as it was permitted. Attached are plan sheets showing the existing conditions according to the survey completed in November and the permitted contours. If you have any questions or need additional information, please do not hesitate to call. We look forward to hearing from you. Sincerely yours, MUNICIPAL ENGINEERING SERVICES CO., PA �%1.1, D.

Mr. Patterson is one of the Division of Waste Management's most experienced staff persons and therefore has a great deal of responsibility. I can assure you that Mr. Patterson inspects the Cherokee County Municipal Solid Waste Landfill facility frequently. However, he cannot be there every day. So we do appreciate your diligent monitoring of the facility's daily operations. In response to your recent complaint concerning odors emanating from the facility, Mr. Patterson conducted a comprehensive audit of the facility on the morning of October 1, 2003. The comprehensive audit includes a complete inspection of the facility water, gas and leachate collection monitoring systems, waste screening, adequacy of waste cover, erosion and sedimentation control, file review, access and safety requirements, and much more. Mr. Patterson reported that during his inspection of the facility, which included walking the perimeter of the landfill, he was unable to smell any objectionable odors. The only area he could smell odors was at the working face of the landfill. He reported in his audit that Cherokee County is doing an excellent job of keeping the refuse covered. He noted no violations on the landfill audit report at this facility during the inspection. Once again, thank you for relaying your concerns to Mr. Jim Patterson in our Asheville Regional Office If you have further questions or comments, please contact Jim Patterson at 828-251-6208, extension 209, or me 919-733-0692, extension 252. _ _ . - _ -- _ � - - Sincerely, Mark Poindexter Field Operations Solid Waste Section c: James Coffey Brent Rockett James Patterson Central File North Carolina LT Department of Environment and Natural Resources • Division of Waste Management Michael F.

Solid Waste Management Rules 1 SA NCAC 13B requires the initiation of assessment monitoring within 90 days under these circumstances (Rule .1634) unless a demonstration can be provided that a source other than the landfill caused the contamination [Rule .1633(c) (3)]. Therefore Cherokee County must fulfill the requirements of Rule .1634, or as allowed by Rule .1633, provide the Solid Waste Section with a demonstration that the tttected contaminants associated with MW-6s did not come from the landfill.
