The County has delineated a defined, isolated area within the C&D landfill footprint of the active phase as shown on Sheets OP-2 through OP-5. The asbestos waste shall be managed in accordance with 40 CFR 61. In accordance with Rule .0542(c)(2), the regulated asbestos waste shall be covered immediately with soil in a manner that will not cause airborne conditions and must be disposed of separate and apart from other solid wastes. Hot loads arriving at the site should be dumped immediately in the designated primary hot load area located near the working face. The designated area must be located only on areas containing compacted refuse covered by at least 12 inches of cover material. The location of the primary hot load area will change along with the landfill development so as to always be near the working face. Hot loads should be Section 2 Waste Acceptance and Disposal Requirements CDM 2-4 extinguished immediately after being dumped by applying water to the burning refuse and by covering the refuse with soil from the stockpile area. If problems are encountered, the local fire department should be called. Once extinguished, the hot load should be observed until it is certain that the fire is out. The remaining refuse should then be compacted and buried at the working face. 2.4 Prohibited Wastes The following wastes will be prohibited from disposal at the Buncombe County C&D Landfill:  Wastewater treatment sludge;  Containers such as tubes, drums, barrels, tanks, cans, and bottles unless they are empty and perforated to ensure that no liquid, hazardous or municipal solid waste is contained within;  Garbage;  Hazardous waste;  Industrial solid waste;  Liquid waste;  Medical waste;  Municipal solid waste;  Polychlorinated biphenyls (PCB) wastes;  Radioactive waste;  Septage;  Sludge;  Special wastes;  White goods; and  Yard trash. The following wastes cannot be received if separate from C&D landfill waste:  Lamps or bulbs including but not limited to halogen, incandescent, neon or fluorescent;  Lighting ballast or fixtures;  Thermostats and light switches;  Batteries including but not limited to those from exit and emergency lights and smoke detectors;  Lead pipes; Section 2 Waste Acceptance and Disposal Requirements CDM 2-5  Lead roof flashing;  Transformers;  Capacitors; and  Copper chrome arsenate (CCA) and creosote treated woods. Waste accepted for disposal in the C&D landfill shall be readily identifiable as C&D waste and shall not have been shredded, pulverized, or processed to such an extent that the composition of the original waste cannot be readily ascertained. The County shall not knowingly dispose any type or form of C&D waste that is generated within the boundaries of a unit of local government that by ordinance:  Prohibits generators or collectors of C&D waste from disposing that type or form of C&D waste.  Requires generators or collectors of C&D waste to recycle that type or form of C&D waste. 2.5 Receiving Prohibited Waste The Buncombe County C&D landfill shall only accept those solid wastes that it is permitted to receive. The County will notify the North Carolina Department of Environment and Nature Resources Division of Waste Management (NCDENR DWM) within 24 hours of attempted disposal of any waste the C&D and Subtitle D landfills are not permitted to receive. A report shall be prepared of any attempted delivery of waste of which the landfill is not permitted to receive, including waste from outside the permitted landfill service area. The report will be forwarded to: Department of Environment and Natural Resources Division of Waste Management Solid Waste Section 1646 Mail Service Center Raleigh, North Carolina 27699-1646 CDM 3-1 Section 3 Cover Material Requirements 3.1 Operational Cover In accordance with Rule .0542(f), the County shall cover disposed C&D waste with six inches of earthen material (or alternative cover material (ACM) approved by the Solid Waste Section (SWS)) when the waste disposal area exceeds one-half acre and at least once weekly. Soil cover shall be used once monthly at a minimum. Cover shall be placed at more frequent intervals if necessary, to control disease vectors, fires, odors, blowing litter, and scavenging. A notation of the date and time of the cover placement must be recorded in the operating record. In accordance with Rule .0542(f)(2), areas which will not have additional wastes placed on them for three months or more, but where final termination of disposal operations has not occurred, shall be covered and stabilized with vegetative ground cover or other stabilizing material. 3.1.1 Wet Weather Operations During wet weather, the County will develop a wet weather working face. The wet weather working face will be kept as small as possible. At the end of disposal operations, the County will cover in accordance with Section 3.1. 3.2 Alternative Cover Material ACM methods are described in this section for Posi-Shell and soil/mulch mixture. Each ACM shall provide control for disease vectors, fires, odor, blowing litter, and scavenging. The ACM approval letter is included in Appendix B. 3.2.1 Posi-Shell The Posi-Shell Cover System is proposed as an ACM (see Appendix C for Manufacturer’s Usage Guide) on waste disposed at the C&D landfill. Posi-Shell provides a thin cover that hardens over the covered waste surface. 3.2.1.1 Properties of Posi-Shell The properties of each component of Posi-Shell are presented in the Manufacturer’s Usage Guide in Appendix C. 3.2.1.2 Cover System Description As described in the Manufacturer’s Usage Guide, the application rate for short-term coverage (overnight cover for daily cover operations) is approximately 8 to 10 square feet per gallon. Assuming the working face is less than one acre (100 feet wide and 400 feet long), the desired load size would be approximately 4,000 gallons. At a minimum, the Posi-Shell material quantities for daily use should be the following:  3,200 gallons of liquid (water or leachate), Section 3 Cover Material Requirements CDM 3-2  8 bags (15 lbs each) of Posi-Pak,  40 bags (50 lbs each) of PSM-200 setting agent, and  80 bags (94 lb each) of optional Portland cement. Posi-Pak is a specially designed plastic fiber with a proprietary finish that provides the reinforcement matrix for the finished cover. PSM-200 setting agent is a blend of clay, polymers, and adhesives that provides thickening, lubrication, and adhesion. Portland cement can be used as a binder component which will help neutralize odors and enhances the durability of the cover system. 3.2.1.3 Cover System Application Procedures Application Procedure Application of the Posi-shell will generally follow the manufacturer’s recommendation and will employ the following minimum procedures:  The Posi-shell will be applied in two different directions to avoid spray shadow or wind dispersion;  The Posi-shell will be applied at the end of each working day;  The Posi-shell surface will be visually inspected on a daily basis for exposed waste and/or inadequate coverage. Inadequate coverage is generally defined as a thickness of less than 1/8 of an inch. Areas of exposed waste and/or inadequate coverage will receive an additional application prior to operations ending for that day. Maximum Daily Area Coverage Based on the July 2008 Airspace Analysis Report:  Annual 2007 waste disposal rate (C&D only) = 66,400 tons  Operating days per year = 284 days  Approximate daily waste disposal rate = 230 tons  In-place density = 0.65 tons of C&D per cubic yard  Daily cubic yards disposed = daily waste disposal rate / in-place density = 350 yd3 or 9,500 ft3 The working face will be restricted to the smallest area feasible. The working lift is typically 4 feet high. Based on a working lift thickness of 4 feet, the working face area is 5,400 square feet (daily cubic yards disposed / working lift thickness), which is less than the daily coverage area. Section 3 Cover Material Requirements CDM 3-3 Daily Depth and Quantity to be Applied N/A Average Monthly Volume of Daily Cover N/A List of Equipment Equipment required for the Posi-Shell consists of a standard hydroseeding unit and a towing unit. Material and Equipment Storage The material components of Posi-Shell will be housed in the machine shop to minimize the risk of hydration. The spraying equipment will be parked in a County designated area which will not impede daily operations. Wet Weather Operation See Section 3.1.1 of this section. Contingency Plans If, for any reason, the County cannot use Posi-Shell as ACM material, soil or a soil/mulch mixture will be used. Screening Criteria N/A 3.2.2 Soil/Mulch Mixture A mulch (30% maximum by volume) and soil mixture is proposed as another ACM material. Mulch will be hauled from the on-site mulching operations and soil will be provided from the County’s on-site borrow area. The soil/mulch mixture will be free of petroleum contaminated soils. The materials will be mixed at the borrow area or the working face. 3.2.2.1 Properties of Soil/Mulch Mixture At the Buncombe County facility, waste segregation occurs at the scale house to prevent the mulch processing of any unacceptable material. Unacceptable material includes construction and demolition debris, potentially contaminated debris, etc. Since waste segregation occurs prior to the waste processing into mulch, the resulting mulch is considered inert. 3.2.2.2 Cover System Application Procedures Application Procedure Application of the soil/mulch mixture will employ the following minimum Section 3 Cover Material Requirements CDM 3-4 procedures:  The mixure will be prepared by combining three (3) loads of mulch and seven (7) loads of soil;  Mix soil and mulch load and visually verify that the mixture is adequately commingled, ensure that there are no large clumps (3 inches in diameter or larger) of either soil or mulch in the mixture;  Load and haul soil/mulch mixture to active working face using an articulating truck; and  Use dozer to cover working face with six inches of soil/mulch mixture. The surface will be visually inspected on a daily basis for exposed waste and/or inadequate coverage. Areas of exposed waste and/or inadequate coverage will receive additional cover. Maximum Daily Area Coverage See Section 3.2.1.3. Daily Depth and Quantity to be Applied As stated above, 6 inches of the soil/mulch mixture will be applied to the daily coverage area of 5,400 square feet. Therefore; the required daily quantity of soil/mulch mixture placed is approximately 100 yd3 (Assuming no other daily cover is used). Average Monthly Volume of Daily Cover As stated above, approximately 100 yd3 per day of soil/mulch mixture will be used. Assuming 24 working days per month, the average monthly volume of daily cover required for normal operating conditions is 2,400 yd3. List of Equipment An articulating truck and dozer will be used for the application process. Material and Equipment Storage Any soil/mulch mixture requiring storage will be stored at the borrow area. Mulch stock pile sizes shall not exceed 30 feet in width and 15 feet in height to avoid spontaneous combustion and to maintain a manageable pile size in the event of a fire. Landfill equipment used for ACM procedures will be stored at County designated areas. Wet Weather Operation Section 3 Cover Material Requirements CDM 3-5 See Section 3.1.1 of this section. Contingency Plans If, for any reason, the County cannot obtain mulch for the on-site processing area for use as ACM material, soil or Posi-shell will be used. Screening Criteria Each soil/mulch mixture load will be visually inspected prior to transport to the working face to determine if the material is adequately mixed. The load will not be placed if the mixture is not commingled adequately or if foreign material is observed. CDM 4-1 Section 4 Spreading and Compacting of Waste The primary goals of waste placement are to (1) maximize the mass of waste landfilled through compaction, (2) minimize erosion and sedimentation impact to the surrounding and disposal areas, and (3) comply with all operating rules and regulations of the North Carolina Solid Waste Section for C&D landfills. 4.1 Working Area In accordance with Rule .0542(g)(1), the County shall restrict solid waste into the smallest area feasible (working face). The working face is defined as where waste is unloaded, inspected, spread, compacted, and ultimately covered with cover material. The working face shall be wide enough to prevent a backlog of vehicles waiting to unload and to allow adequate working space for landfill equipment. At a maximum, the width of the working face shall not exceed 100 feet. 4.2 Compaction Per Rule .0542(g)(2), solid waste shall be compacted as densely as practical into cells. Proper waste spreading and compaction is necessary both to conserve the capacity of the disposal areas and to minimize future settlement. C&D waste will be unloaded, inspected for unacceptable items, and spread on the working face. Each layer shall be compacted with a dozer. 4.3 Controlling Wind Blown Material In accordance with Rule .0542(g)(3), appropriate methods such as fencing and diking shall be provided as needed within the landfill area to confine solid waste which is subject to be blown by the wind. At the conclusion of each day of operation, all windblown material at the landfill site shall be collected and returned to the working face. 4.4 Filling Sequence Yearly operational grades are provided per Rule .0542(b)(1)(B) on Sheets OP-2 to OP- 5. 1Final Grades for the original Phase 5 and the 0.48 acre expansion are shown on C-103. 1 Revision for Phase 5 Expansion prepared by McGill Associates, P.A. in August 2015. Section 5 Disease Vector Control In accordance with Rule .0542(h), the County shall prevent or control on-site populations of disease vectors using techniques appropriate for the protection of human health and the environment. Disease vectors are defined as any rodent, flies, mosquitoes, or other animals or insects, capable of transmitting disease to humans. Effective vector control measures shall be applied when necessary. Control of vectors will be maintained by application of well-compacted cover material over the compacted solid waste. This will protect against migration of vectors into and from the landfill. Stagnant ponding water should be prevented to control mosquito breeding. Filling in low spots should be performed regularly, and if necessary, County mosquito control or a licensed exterminator shall be employed to control vectors. A 5-1 Section 6 Air Criteria and Fire Control 6.1 State Implementation Plan In accordance with Rule .0542(i)(1), the County shall ensure that units do not violate any applicable requirements developed under a State Implementation Plan (SIP) approved or promulgated by the U.S. EPA Administrator pursuant to Section 110 of the Clean Air Act, as amended. The Western North Carolina Regional Air Quality Agency was contacted during September 2008 and they indicated that two air quality regulations, which are in the local code, apply to the C&D landfill. They are as follows: • Chapter 4.0540 – Particulates from Fugitive Non-Process Dust Emission Sources • Chapter 4.1806 – Control and Prohibition of Odorous Emissions Chapter 4.0540 states that the C&D landfill shall not cause, permit, suffer or allow particulate matter to become airborne in the ambient air as a result of storage, transportation, processing, or handling of materials or refuse without taking reasonable precautions, approved by the Board, for the prevention of such particulate matter from becoming airborne. Additionally, the C&D landfill shall not cause, permit, suffer or allow particulate matter to become airborne in the ambient air as a result of the construction, alteration, maintenance, repair or demolition of any road, bridge, tunnel, railroad track right of way, vehicle, equipment, machinery, building or structure without taking reasonable precautions, approved by the board, for the prevention of such particulate matter from becoming airborne. As described in Section 7.4 of this plan, dust control measures are used throughout the facility and will be continuously used during the construction and operation of any phase of the C&D landfill.  Chapter 4.1806 states that the C&D landfill shall not operate the facility without implementing management practices or installing and operating odor control equipment sufficient to prevent odorous emissions from the facility from causing or contributing to objectionable odors beyond the facility's boundary. Any potential odors resulting from the C&D landfill are control by the use of operational cover. Additionally, the working face is kept to the smallest feasible area and disposal occurs in areas that are protected from the prevailing winds.   6.2 Open Burning of Waste Per Rule .0542(i)(2), open burning of solid waste, except for the approved burning of land clearing debris generated on-site or debris from emergency clean-up operations, is prohibited at the C&D landfill. Prior to any burning, a request shall be sent to the NCDENR DWM for review. The DWM will determine if the burning to be approved is one of the two types of burning as described above. A notation of the date of A 6-1 Section 6 Air Criteria A 6-2 approval and the name of the Division personnel who approved the burning shall be included in the operating record. 6.3 Fire Protection Equipment In accordance with Rule .0542(i)(3), equipment shall be provided to control accidental fires and arrangements shall be made with the local fire protection agency to immediately provide fire-fighting services when needed. Fires that break out close to the surface of the fill area should be dug out and smothered with cover material. Deep fires should be smothered out by placing moist soil on the surface and by constructing soil barriers around the fire. Where the smothering technique fails, the burning material shall be excavated and smothered or quenched with water once the burning material is brought to the surface. Water is usually not effective unless it can be directly applied to the burning material. 6.4 Fire and Explosion Notification Per Rule .0542(i)(4), fires and explosions that occur at a C&D landfill require verbal notice to the DWM within 24 hours and written notification within 15 days. Written notification shall include the suspected cause of fire or explosion, the response taken to manage the incident, and the action(s) to be taken to prevent the future occurrence of fire or explosion. Verbal and written notification shall be submitted to: Department of Environment and Natural Resources Division of Waste Management Solid Waste Section 1646 Mail Service Center Raleigh, North Carolina 27699-1646 (919) 733-4810 Section 7 Access and Safety Requirements 7.1 Landfill Access and Security In accordance with Rule .0542(j)(1), the Buncombe County C&D Landfill must be adequately secured by means of gates, chains, berms, fences and other security measures approved by the DWM to prevent unauthorized entry. All vehicles disposing of waste at the facility enter and leave through the access control gate. All waste entering the landfill must be weighed at the scale where a full- time Scale Operator verifies compliance with operation requirements. Unauthorized vehicle access to the site is prevented around the remaining portion of the landfill property by fencing, steep gradient, woods, wetlands, gates, and storm water ditches. 7.2 Attendant Per Rule .0542(j)(2), an attendant shall be on duty at the site at all times while the facility is open for public use to ensure compliance with operational requirements. A full-time Scale Operator will be located in the scale house during operating hours. The Scale Operator will verify compliance with operation requirements. In addition, a Facility Supervisor will be present on-site at all times during operation. 7.3 Access Road In accordance with Rule .0542(j)(3), the access road to the site and access roads to monitoring locations shall be of all-weather construction and maintained in good condition. Potholes, ruts, and debris on the roads will receive immediate attention in order to avoid damage to vehicles. Access roads will be regraded as necessary to maintain positive slope for adequate drainage. 7.4 Dust Control Per Rule .0542(j)(4), dust control measures shall be implemented when necessary. Minimum dust control will include a water truck for wetting of dusty roads. Sprinklers are also used along some portions of the landfill perimeter access road. Petroleum products shall not be used for dust control. 7.5 Signs In accordance with Rule .0542(j)(5), a sign providing information on disposal procedures, the hours during which the site is open for public use, the permit number and other pertinent information specified in the permit conditions is posted at the site entrance. In accordance with Rule .0542(j)(6), signs are clearly posted stating that no liquid, hazardous and municipal solid waste can be disposed in the C&D landfill. A 7-1 Section 7 Access and Safety Requirements A 7-2 In accordance with Rule .0542(j)(7), traffic signs or markers are provided to promote an orderly traffic pattern to and from the discharge area and to maintain efficient operating conditions. 7.6 Waste Removal Scavenging Policy Per Rule .0542(j)(8), the removal of solid waste from the C&D landfill is prohibited. A recycling program can be implemented which would allow removal of solid waste if program is approved by DWM. Currently, the County does not have a recycling program. Section 8 Erosion and Sedimentation Control Requirements 8.1 Control of Sediment In accordance with Rule .0542(k)(1), adequate sediment control measures shall be utilized to capture and control sediment in order to prevent sediment from impacting wetlands and off-site properties. Surface water runoff passing through the C&D landfill site shall be diverted to the sediment ponds by the use of ditches, berms, and pipes as shown on the Operation Drawings. Existing Sediment Pond 11 was constructed in accordance with the approved Sediment and Erosion Control Plan for control of onsite stormwater run-off and sediment transport from landfill operations. Sediment Pond 12 is proposed for control of Phase 5 expansion stormwater. Additionally, existing Sediment Ponds 10 and 11 will be modified. The sediment ponds have been designed in such a manner that releases will not overload downstream drainage features or damage adjacent property. Sediment accumulated in the ponds shall be removed as specified in the approved Sediment and Erosion Control permit. Silt gages shall be installed in all ponds as shown on the Detail Sheets in the Engineering Plan. Ditches require frequent inspection for sediment buildup. At a minimum, the sediment buildup should be assessed after all significant rain events. 8.2 On-Site Erosion Control Per Rule .0542(k)(2), adequate erosion control measures consisting of vegetative cover, materials, structures or devices shall be utilized to prevent excessive on-site erosion of the C&D landfill. Erosion control measures shall include: A. Disturbing as little area as practical at any one time for landfilling operations. B. Seeding/Mulching of all disturbed areas commencing as soon as practically possible. Employing erosion netting or sod on steep slopes and other erosion prone areas. C. Use of earthen berms, hay bales, silt fences, riprap or equivalent devices down-gradient of disturbed areas, stockpiles, drainage pipes inlets and outlets and at intervals along grassed waterways, until such time as permanent vegetation is established. D. Placement of riprap at the inlets and outlets of stormwater piping. A 8-1 Section 8 Erosion and Sediment Control Requirements A 8-2 8.3 Vegetative Cover In accordance with Rule .0542(k)(3), vegetative ground cover sufficient to restrain erosion shall be accomplished as directed by appropriate state or local agency upon completion of any phase of C&D landfill development consistent with Rule .0543(c)(5). Riprap, haybales, or other acceptable temporary methods of erosion control may be required until permanent cover is established. Mulching, until a vegetative cover is established, can stabilize areas where final grade has been reached. Soil mulching can be achieved using wood chips, straw, hay, asphalt emulsion, jute matting, and synthetic fibers. Mulches allow for greater water retention; reduce the amount of runoff; retain seeds, fertilizer, and lime in place; and, improve soil moisture and temperature conditions. Temporary seeding shall be applied in accordance with the NC Erosion and Sediment Control Planning and Design Manual, June 2006. CDM 9-1 Section 9 Drainage Control and Water Protection Requirements 9.1 Surface Water Diverted From Operational Area In accordance with Rule .0542(l)(1), surface water shall be diverted from the operational area. Excessive surface water at the working face creates difficulties for maneuvering equipment and prevents the operator from achieving maximum compaction of the waste. To divert surface runoff away from the working face, temporary diversion berms shall be installed on the current lift, up-gradient from the working face and in other locations as dictated by the direction of grade. The area between the temporary berm and the working face should be limited to one acre to prevent excessive ponding. The soil cover in the areas beyond the diversion berms shall be uniformly graded and compacted to prevent the formation of erosion channels. In the event that channels do form, the cover shall be promptly repaired. During the formation of the initial lift of each phase area additional measures shall be employed to divert surface water. Existing phases were graded with a high point located within each phase. The high point will separate each phase into two distinct areas from the perspective of stormwater control. Initial disposal operations for each phase will begin on only one side of the high point. 9.2 Surface Water Shall Not Be Impounded Over Waste Per Rule .0542(l)(2), surface water shall not be impounded over or in waste. Completed areas shall be adequately sloped at a minimum of 5% to allow surface water runoff in a controlled manner. 9.3 Waste Shall Not Be Disposed Of In Water In accordance with Rule .0542(l)(3), solid waste shall not be disposed of in water. The minimum four-foot separation between waste and the seasonal high groundwater table along with the drainage controls described in Section 8 will prevent waste from being disposed of in water. 9.4 Leachate Containment Operational cover is placed on the C&D landfill working face to minimize leachate generation. Any leachate generated is contained by existing and proposed stormwater control devices per Rule .0542(l)(4).2 9.5 Pollutant Discharge Operations shall not cause discharge pollutants or discharge of nonpoint source of pollution in accordance with Rule .0542(l)(5).2 2Revision for Phase 5 Expansion prepared by McGill Associates, PA in August 2015. Section 10 Survey for Compliance In accordance with Rule .0542(m), within 60 days of the County's receipt of the DWM's written request, the County shall conducted a survey of the active or closed portions of the C&D landfill in order to determine whether operations are being conducted in accordance with the approved design and operational plans. The County shall report the results of such survey, including a map produced by the survey, to the DWM within 90 days of receipt of the DWM's request. The survey shall be performed by a land surveyor registered in North Carolina. A 10-1 CDM 11-1 Section 11 Operating Record and Record Keeping Requirements 11.1 Regulatory Requirements In accordance with Rule .0542(n)(1), the county shall record and retain at the facility the following information as it becomes available:  Records of random waste inspections, monitoring results, certifications of training, and training procedures required by Rule .0544;  Amounts by weight of solid waste received at the C&D landfill, include county of generation;  Any demonstration, certification, finding, monitoring, testing, or analytical data required by Rules .0544 through .0545;  Any closure or post-closure monitoring, testing, or analytical data as required by Rule .0543;  Any cost estimates and financial assurance documentation required by Rule .0546;  Notation of date and time of placement of cover material; and  All audit records, compliance records and inspection reports. 11.2 Operating Record Per Rule .0542(n)(2), all information contained in the operating record must be furnished to the Division according to the permit or upon request, or be made available for inspection by the Division. The operating record must also include: (A) A copy of the approved operation plan required by this Rule and the engineering plan required by Rule .0539; (B) A copy of the current Permit to Construct and Permit to Operate; and (C) The Monitoring Plan, in accordance with Rule .0544 of this Section, included as appendices to the Operation Plan. 11.2.1 Monitoring Plan In accordance with Rule .0542(n)(3)(C), a monitoring plan per Rule .0544 shall be included as appendices to the Operation Plan. The groundwater and surface water monitoring plan was prepared per Rules .0544(b) and (c) and is included as Appendix A. Rule .0544(d) requires a gas control plan and is included as Appendix B. Section 11 Record Keeping Requirements CDM 11-2 Rule .0544(e) requires a waste acceptability program. Currently, this program is in place with the MSW landfill and was approved in the aforementioned Permit submittal. Since both landfills are integral parts of the solid waste management facility, the previously approved waste acceptability plan covers the C&D landfill as well.

This document is intended to fulfill all of the specified criteria delineated in this rules. 1 Purpose and Scope The purpose of this Water Quality Monitoring Plan is to address the requirements in Rule .0544 (b) and (c), and to present a plan for groundwater and surface water monitoring for the proposed Buncombe County C&D Landfill Phase 5 expansion. The Water Quality Monitoring Plan includes information on the expansion of the existing groundwater monitoring network, surface water monitoring plan, sampling and analysis requirements, and detection monitoring requirements. The groundwater monitoring network was designed based on information obtained from recent and previous subsurface investigations and a review of literature pertaining to regional geology and groundwater resources. A detailed discussion of the geologic and hydrogeologic conditions at the Phase 5 C&D expansion is presented in both the Site Plan Application and the Design Hydrogeologic Report for the C&D expansion area. The Water Quality Monitoring Plan includes the elements necessary to address the groundwater monitoring plan, including information on the existing and proposed groundwater monitoring system, sampling and analysis requirements, and detection monitoring requirements in accordance with Rule .0544(b)(1)(A) through (E). In addition, the Plan discusses provisions necessary to meet the requirements of a surface water monitoring plan as described in Rule .0544(c). 2 Geologic Setting The Buncombe County Landfill site is located in the Blue Ridge Mountains approximately 9 miles north of Asheville, North Carolina. The landfill site consists of 557 acres bounded by the French Broad River to the south and west, Blevin Branch to the north, and Flat Creek to the east. The site consists of moderate to steep slopes separating narrow hills and ridges from small incised secondary drainages. 2.1 Site Geology Detailed discussions of the site geology are provided in the Site Hydrogeologic Report and Phase 5 Expansion Design Hydrogeologic Report. The following section provides a summary of the site geology for the purposes of this Plan. The Geologic Map of North Carolina shows the site to be underlain by a Precambrian Migmatitic biotite-hornblende gneiss unit (NCGS 1985). The site vicinity was mapped as primarily granite and undifferentiated gneiss (Weiner 1970 and GRAM 1999). Small localized areas of alluvium and/or colluvium were encountered near the base of the secondary drainage features. These soils generally consisted of clays to silty Appendix A Water Quality Monitoring Plan A 2 P:\Buncombe - 6447\65973 C&D Substantial Amdmt\Reports\Permit to Construct and Sub Amdmt\6 - Operation Plan\AppA - GW and SW Monitoring Plan\Appendix A.docx sand with rock fragments. Typically, the uppermost layer consisted of residuum soils (saprolite) which generally consist of stiff sandy silts and dense clayey. The saprolite grades into partially weathered rock (PWR). PWR was encountered in the borings as indicated by a blow count greater than 50 blows per six inch interval. The thickness of saprolite and PWR was greatest in upland areas, and least in the bottom of secondary drainage features. Depth to bedrock in the Phase 5 C&D Expansion area, defined as depth to auger refusal, ranges from 3.5 feet in B-620 up to 29 feet in B-618. The average bedrock depth was approximately 15 feet over the proposed Landfill expansion area. The top of bedrock is typically a reflection of surface topography, with shallow bedrock in the secondary drainage features, and deeper bedrock in upland areas. 2.2 Site Hydrogeology As with bedrock, the potentiometric surface is a subdued reflection of surface topography. As discussed in Design Hydrogeologic Report, groundwater flow in the Phase 5 expansion area is to the North towards Blevin Branch. Groundwater is rarely present above the bedrock surface; groundwater was present in the shallower lithological units only in one location in the bottom of secondary drainage feature within the area, at B-619. The bedrock fracture flow system behaves similar to an anisotropic porous media, based on the potentiometric mapping for the Phase 5 area and results of pumping tests conducted during previous investigations at the Buncombe County site (CDM, 1995, 2002). The depth of groundwater circulation beneath the area is estimated at approximately 100 feet below ground surface (bgs), based on analysis of the regional flow system as discussed in the previous Design Hydrogeologic Reports (CDM, 1995). Thus, groundwater monitoring can be focused on depths of less than 100 feet bgs. As discussed in the Phase 5 C&D landfill expansion Design Hydrogeologic Report, groundwater flow converges into the secondary drainage feature; therefore this drainage feature is an important target for groundwater monitoring. 3 Proposed Groundwater Monitoring Network This section presents the proposed groundwater monitoring network for the Phase 5 expansion area. Section 3.1 presents proposed monitoring well locations, Section 3.2 discusses monitoring well installation and construction specifications, Section 3.3 discusses hydraulic conductivity testing of the monitoring wells, and Section 3.4 discusses the surface water quality monitoring plan. Existing and proposed monitoring well locations are provided on Sheet 1. 3.1 Monitoring Well Locations The SWS regulations require that upgradient monitoring well(s) be located so that groundwater samples collected from the uppermost aquifer provide an indication of background groundwater quality. Upgradient wells MW-1 and MW-1d have already been installed to monitor background water quality for the entire site. No additional Appendix A Water Quality Monitoring Plan A 3 P:\Buncombe - 6447\65973 C&D Substantial Amdmt\Reports\Permit to Construct and Sub Amdmt\6 - Operation Plan\AppA - GW and SW Monitoring Plan\Appendix A.docx background wells are proposed for the area. The downgradient monitoring wells must represent groundwater quality at the relevant point of compliance. The wells must be located in similar geologic units so that upgradient and downgradient groundwater quality data can be compared. The current groundwater monitoring system is shown in Sheet 1. This sheet shows the Subtitle D Landfill Cells 1-6 and the existing C&D Landfill and the relationship of the monitor wells to the cells. Monitoring wells MW-2/2d, MW-3/3d, MW-4/4d, MW- 5/5d, MW-6/6d, MW-7, MW-8/8d, MW-10/10d, MW-11/11d, and MW-13/13d are located around Cells 1-6 of the Subtitle D landfill. Monitoring well nests MW-12/12d and MW-14/14d are located downgradient of the existing C&D landfill. The location of the background well nest (MW-1/1d) is shown on Sheet 1. Table 1 lists the existing monitoring well network, the proposed monitoring well nest for the Phase 5 area, the approximate depth of completion for the proposed wells, and the rationale for each location. As the groundwater beneath the site is a three dimensional system, nested point of compliance wells are proposed for the Phase 5 expansion. In locations in which saturation occurs above the bedrock surface, the shallow monitoring well will be completed in the saprolite or PWR. If a sufficient thickness of saturated saprolite/PWR zone is found, then the well will be installed in this zone. The zone should be of sufficient thickness to account for seasonal fluctuations in the water table. If a sufficient saturated thickness is not present, then the boring will be advanced into the bedrock and the well will be screened across the saprolite and bedrock contact. As discussed in the Design Hydrogeologic Report, saturated conditions above bedrock do not appear to be found in the bottom of secondary drainage feature. In locations in which no saturation is encountered above the bedrock surface, the shallowest completion will be in bedrock. The bedrock monitoring wells at each location will target the shallowest water-bearing fracture zones encountered. Drilling observations and air lift yield tests will be utilized to identify fractured zones. The following nomenclature will be used for the Phase 5 C&D expansion nested monitoring wells: MW-15 Proposed shallow monitoring well at location # 15. Within the secondary drainage feature, downgradient of the proposed Phase 5 C&D landfill, with the screened interval in the saprolite/ bedrock contact, if present, or across the first encountered water-bearing fracture. MW-15d Proposed deep monitoring well at location # 15, with the screened interval in the next deepest conductive fracture zone in the bedrock aquifer.

An example of a monitoring well nest is shown on Figures 1a and 1b. The monitoring wells at locations of potentially saturated saprolite or PWR will be installed by advancing the borehole through the water table using hollow-stem augering techniques. Soil samples will be collected at five-foot intervals with a split spoon sampler in accordance with ASTM D- 1586. Soil lithology will be described in the field by an onsite geologist to develop a borehole log. If saturation conditions are not evident upon refusal of hollow stem auger drilling, then a temporary well screen will be placed in the hole for a period up to 48 hours to determine whether the well will yield water. If no saturation is expected or encountered during hollow stem auger drilling, then the shallowest well will be installed in the upper portion of the bedrock aquifer utilizing air rotary drilling techniques. During air rotary drilling, drilling observations will be recorded by an onsite geologist, including observed fractures and lithologic descriptions from cuttings. Drilling will proceed until the first water-bearing fracture is encountered. Upon observing a fracture (an evident drop of the drill rod and/or a change in drill chatter), then an air lift yield test will be conducted. The drill rod will be raised at least 10 feet, and operations will cease for a period of 30 minutes. After the 30 minute period, the drill rod will be lowered to the bottom of the hole, and air will be blown for a period of 10 minutes. The amount of water coming from the hole at this time (if any) will be estimated in gallons per minute. If the borehole is dry, then the drill rig will be moved approximately 20 feet, and the above procedure repeated. At locations in which a deeper well is desired, the deep well will be drilled after the shallow well, and installed at least 10 feet deeper than the bottom of the shallow borehole. The deeper well will target the next conductive fracture zones encountered at depth. The above procedure for observing fractures and performing air lift yield tests will be applied. If no evident fractures are encountered at a depth between 20 and 35 feet below the bottom of the shallow well, then drilling will continue to until a fracture zone is encountered. Since the wells will be located between the landfill and the groundwater discharge feature, it is anticipated that most wells will be completed within 100 feet of ground surface. Also, based on observed subsurface conditions, it appears that the more conductive fracture zones will be encountered within the upper 100 feet of the bedrock. However, if subsurface conditions dictate that a deeper completion is required, then the wells will be installed at that depth. All the deeper monitoring wells will target the most conductive fracture zones, regardless of depth.

The shallow monitoring well will be constructed with five to ten feet of 0.010-inch slot screen at the end of the casing string placed so that it brackets the water table. This actual length of screen will be chosen to dependent upon depth to the water table and bedrock. The deeper monitoring well will be constructed with an outer casing extending from the ground surface into the bedrock beyond the bottom of the shallower monitoring well screen. A five foot screen interval will be used to monitor the targeted fracture. The PVC casing string in each well will extend approximately three feet above ground surface. A sand pack will be placed around the screen interval to a maximum of two feet above the top of the screen. A two foot thick bentonite seal consisting of hydrated bentonite pellets will be placed on top of the sand to hydraulically seal the completion interval. The remainder of the annulus will be sealed with a bentonite-Portland cement grout to ground surface. A protective outer casing with a lockable cap will be placed over the PVC casing and into the grout, extending 2.5 to 3 feet below ground surface. Following completion, the monitor wells will be developed to remove the residual effects of drilling. The wells will be developed using a combination of surging and over-pumping. All drilling and down-hole equipment will be decontaminated by steam cleaning between borings. Well development equipment will be decontaminated by washing in a non-phosphate detergent solution followed by a potable water rinse, then a distilled water rinse, and allowed to air dry. The horizontal location of all new monitor wells will be surveyed in State Plane Coordinates by a Registered Land Surveyor to the nearest 0.1 foot. The vertical control or elevation of the top of PVC casing (the well measuring point) will be surveyed to the nearest 0.01 foot accuracy to mean sea level (msl). The height of the well measuring point above ground surface will be measured. 3.3 Hydraulic Conductivity Testing Following installation and development of the new monitor wells, the hydraulic conductivity of the aquifer material surrounding each well will be determined by conducting slug falling head and/or recovery tests on each well. During drilling operations, where possible, saturated saprolite samples will be collected for laboratory testing of porosity. 3.4 Surface Water Quality Monitoring Plan Five surface water sampling stations already exist to monitor the effects of landfill operations on surface water quality in Blevin Branch. Two sampling stations (SW-1 and SW-2) are located both upstream and downstream of the disposal Cells 1-6 of the Subtitle D landfill. Surface water sampling location, SW-3, is located at the outfall for the spring capture system located west of Cell 1. Surface water sampling location, SW-5, is located at the outfall for the spring capture system located north of Cell 6. Appendix A Water Quality Monitoring Plan A 10 P:\Buncombe - 6447\65973 C&D Substantial Amdmt\Reports\Permit to Construct and Sub Amdmt\6 - Operation Plan\AppA - GW and SW Monitoring Plan\Appendix A.docx SW-4 is located within the drainage feature downgradient of MW-14/14d at the existing C&D landfill. Surface water sampling station SW-6 is proposed for Blevin Branch, north of the Phase 5 area. The existing and proposed sampling locations are shown on Sheet 1. 4 Sampling and Analysis Plan 4.1 Introduction Rule .0544 specifies that the owner/operator must provide, as part of the groundwater monitoring program, a groundwater and surface water sampling and analysis (S&A) plan. The S&A plan should be designed to provide accurate results of groundwater quality at the upgradient and downgradient sampling locations. The S&A plan will address the following subjects: „ Groundwater and surface water sample collection „ Sample preservation and shipment „ Analytical procedures „ Chain-of-custody „ Quality assurance/quality control (QA/QC) 4.2 Groundwater and Surface Water Sample Collection Groundwater samples will be collected from each monitoring well and surface water sampling location. Samples from each monitoring well and surface water sampling location will be sampled on a semi-annual basis. One sample from the new monitoring wells (MW-15/15d) and surface water sampling location (SW-6) will be collected prior to the Phase 5 expansion receiving waste. 4.2.1 Static Water Level Measurements Static water level elevations will be measured at each monitoring well prior to any purging or sampling activities. Static water level data will be used to monitor changes in site hydrogeologic conditions. The following measurements will be recorded in a dedicated field book prior to sample collection: „ Height of the well measuring point above ground surface, „ Depth of water in the well from the TOC measuring point (to the nearest 0.01 foot), „ Total depth of the well, „ Height of the water column in the well casing. Appendix A Water Quality Monitoring Plan A 11 P:\Buncombe - 6447\65973 C&D Substantial Amdmt\Reports\Permit to Construct and Sub Amdmt\6 - Operation Plan\AppA - GW and SW Monitoring Plan\Appendix A.docx An electronic water level indicator will be used to accurately measure water elevations to within 0.01 foot within the same day in as short a period of time as possible. Each well will have a permanent, easily identified reference point from which all water level measurements will be taken. The reference point will be marked and the elevation surveyed by a North Carolina Registered Land Surveyor. 4.2.2 Detection of Immiscible Layers USEPA's Technical Manual for Solid Waste Disposal Facility Criteria outlines specifications for groundwater sampling and analysis. One of these specifications outlines the establishment of provisions for detecting immiscible fluids, if applicable. Typically, immiscible fluids are categorized as either, (1) light, non-aqueous phase liquids (L-NAPLs), or (2) dense, non-aqueous phase liquids (D-NAPLs). L-NAPLs are more commonly referred to as "floaters" due to their relatively lighter specific gravity, while D-NAPLs are typically referred to as "sinkers" due to their relatively denser specific gravity. In most instances, the probability of immiscible fluids being present and subsequently detected in groundwater monitoring wells surrounding C&D landfills is somewhat remote because chemical products (such as industrial solvents) are not accepted for storage or disposal at C&D waste management facilities. However, for those rare instances where a separate immiscible phase is believed to be present, EPA suggests that provisions for detecting these types of fluids should be developed. The following procedure is proposed to address these concerns in the event that the SWS ever requires this test to be performed. In those instances where the monitoring well screened interval encompasses the water table surface, the ability to detect and sample light non-aqueous phase liquids (LNAPLs) prior to implementation of routine groundwater sampling activities may exist. To accomplish this objective, a transparent Teflon bailer will be lowered into the well to just below the water table surface. The bailer will then be removed from the well and the contents examined to identify if any immiscible fluids are present. If any immiscible fluids are determined to be potentially present, an interface probe is proposed to be used. The depth of the light phase immiscible layer as determined by the interface probe, will then be recorded in a field logbook. The interface probe will continue to be lowered until it intersects the groundwater table surface. The depth of the fluid/water interface zone also will be recorded. From these two measurements, the thickness of the light phase immiscible layer can be readily determined. The potential presence of dense phase immiscible layer will be determined by the examination of laboratory analytical results. Analytical results above a percentage of a given chemicals solubility limit can indicate the potential presence of DNAPLs. As mentioned above, monitoring for immiscible phase fluids is not envisioned to be performed during typical sampling events, but is provided here to document how the test will be performed if the SWS requires it at a future date. Appendix A Water Quality Monitoring Plan A 12 P:\Buncombe - 6447\65973 C&D Substantial Amdmt\Reports\Permit to Construct and Sub Amdmt\6 - Operation Plan\AppA - GW and SW Monitoring Plan\Appendix A.docx 4.2.3 Monitoring Well Evacuation Following measurement of the static water level in all of the wells, individual wells will be purged of all stagnant water. The stagnant water, which is not representative of true aquifer conditions, will be removed to ensure that fresh formation water can be sampled. A minimum of three well casing volumes will be removed prior to sampling the well. The well volume for 2-inch diameter wells will be calculated using the following equation: One well volume in gallons equals the height of the water column (in feet) times 0.1632 (slightly less than 0.5 gallons per foot water for 3 casing volumes). Because aquifer formations onsite are relatively low-yield, the well will be purged in such a way that water is removed from the bottom of the screened interval. During the well purging process, field measurements (pH, temperature, specific conductance, dissolved oxygen, oxidation/reduction potential and turbidity) will be collected at regular intervals, and reported in a tabular format. The well will be purged until field measurements stabilize within approximately 10 percent between subsequent readings or until the well is dry. Stabilization of these measurements will indicate that fresh formation water is present in the well. Field measurements of pH, temperature, conductivity, dissolved oxygen, and ORP will be obtained by using a YSI-600 series multi-parameter meter or equivalent and turbidity readings will be collected with Lamont turbidity meter or equivalent. Field measurements collected during purging activities will be recorded in the field logbook. If the well is purged to dryness, the samples will be collected after a sufficient volume of water has entered the well to allow collection of the sample. Wells will be purged using a decontaminated Teflon bailer with new nylon rope or an acceptable pumping device approved by the SWS. Teflon bailers will be pre- decontaminated by the manufacturer. No field decontamination of bailers will be performed. 4.2.4 Sample Collection After purging activities are complete, groundwater samples will be collected for laboratory analysis. The wells will be sampled using disposable laboratory decontaminated Teflon bailers equipped with new nylon rope. Bailers will be used for one well only. Field decontamination of bailers will not be permitted. The bailers will be lowered slowly into the well to minimize sample agitation. Sample water will be placed directly into sample bottles provided by the analytical laboratory, using the following method: 1. Retrieve bailer and slowly transfer sample water to the appropriate sample container. The bailer should not be allowed to touch the sample container. 2. The sample container for the volatile organic compounds should be filled first, leaving no headspace or air bubbles. The container should then be tightly sealed. The sample containers will be pre-preserved. No field preservation will be performed. Appendix A Water Quality Monitoring Plan A 13 P:\Buncombe - 6447\65973 C&D Substantial Amdmt\Reports\Permit to Construct and Sub Amdmt\6 - Operation Plan\AppA - GW and SW Monitoring Plan\Appendix A.docx 3. The sample container for the metals should then be filled. This container should be filled to the bottle shoulder. Surface water samples will be obtained from areas of minimal turbulence and aeration. The following procedure will be implemented regarding sampling of surface waters: 1. Hold the bottle near the bottom with one hand, and with the other, remove the cap. 2. Push the sample container slowly into the water and tilt up towards the current to fill. A depth of about six inches is satisfactory. Avoid breaching the surface while filling the container. 3. The container should be moved slowly, in a lateral direction, if there is little current movement. 4. If the stream depths are too shallow to allow submersion of the sample container, a pool may be scooped out of the channel bottom and allowed to clear prior to sampling. 5. Lift the container from the water and place the uncontaminated cap on the container. The wells and surface water stations will be sampled in the order of potential for increasing contamination levels beginning with the upgradient (background) sampling locations. The individual water samples for C&D landfill wells (MW- 12/12d, MW-14/14d, and proposed MW-15/15d) will be collected in the order of parameter volatility. The collection order for the samples will be as follows: „ Volatile organic compounds (VOCs), „ Chloride, „ Sulfate, „ Alkalinity, „ Total Dissolved Solids (TDS), „ Total metals (including manganese, mercury and iron). The samples will be transferred from the sampling equipment directly into a prepared sample container provided by the laboratory. Field filtering of samples is not permitted. There will be a specific size and type of container provided for each constituent to be analyzed. For VOC analysis, the containers provided will be pre- preserved 40-ml glass vials. For metals analysis, the samples will be collected in pre- Appendix A Water Quality Monitoring Plan A 14 P:\Buncombe - 6447\65973 C&D Substantial Amdmt\Reports\Permit to Construct and Sub Amdmt\6 - Operation Plan\AppA - GW and SW Monitoring Plan\Appendix A.docx preserved 500-ml HDPE bottles. Chloride, sulfate, alkalinity and TDS will be collected in unpreserved 500-ml HDPE bottles. Extra containers will be provided in case of accidental breakage. All field personnel will wear protective latex disposable gloves in order to prevent extrinsic contamination from clothing, body oils, dirt, and other various contaminants. Sample documentation requirements to ensure sample integrity, will include sample locations, date and time of sample collection, proper analysis, and preservative (if applicable). 4.3 Sample Preservation and Shipment In order to ensure sample integrity, preservation and shipment procedures will be carefully monitored. Generally, ice and chemical additives will be used as sample preservatives, as recommended by the commercial laboratory. For VOC analysis, hydrochloric acid will be used as the preservation method as well as maintaining the samples at a temperature of 4°C. Nitric acid will be used as the preservative for samples needing metals analysis. If the analytical laboratory is located some distance from the site, samples shall be shipped via a 24-hour delivery service to ensure holding times are not exceeded. Shipment of samples will be coordinated with the laboratory. Proper storage and transport conditions must be maintained in order to preserve the integrity of the sample. Once collected, samples will be placed on ice and cooled to a temperature of 4°C. Samples are to be packed in coolers so as to inhibit breakage or accidental spills. Custody seals will be placed on the outside of the cooler, in a manner to detect tampering of the samples. The laboratory shall immediately notify the owner/operator of any samples that arrive with custody seals broken. 4.4 Analytical Procedures The samples taken from each monitoring well at the C&D landfill facility will be analyzed for the constituents listed in 40 CFR Part 258, Appendix I plus mercury, chloride, manganese, sulfate, iron, alkalinity, and Total Dissolved Solids. The surface water samples collected at the C&D landfill will be analyzed for Appendix I constituents only. The analytical procedures for the indicated parameters will be conducted using the following methods: Analysis EPA Method Number Volatile organic compounds 8260 Total metals 6010 Mercury 7470 Chloride 300.0 Appendix A Water Quality Monitoring Plan A 15 P:\Buncombe - 6447\65973 C&D Substantial Amdmt\Reports\Permit to Construct and Sub Amdmt\6 - Operation Plan\AppA - GW and SW Monitoring Plan\Appendix A.docx Sulfate 300.0 Alkalinity SM 2320B Total Dissolved Solids SM 2540C 4.5 Chain of Custody It is imperative that an accurate record of sample collection, transport, analysis, and disposal be maintained and documented. Therefore, chain-of-custody procedures will be instituted and followed throughout the sampling program. It is necessary to establish documentation to trace sample possession from the time of collection until disposal. The chain-of-custody program shall include the following requirements: „ Samples shall be accompanied by a chain-of-custody record that notes the date and time of collection as well as sampling personnel. „ All samples shall be properly labeled to prevent misidentification of samples. „ A sample analysis sheet shall accompany all samples to the laboratory. „ Sample custody seals shall be used to indicate any tampering of samples. „ All records pertaining to the shipment of a sample shall be retained (freight bills, post office receipts, and bills of lading). The laboratory shall not accept samples for analysis without a correctly prepared chain-of-custody form. The laboratory shall be responsible for maintaining chain-of- custody of the sample(s) from time of receipt to disposal. The chain-of-custody form shall be signed by each individual who possesses the samples. To prevent sample misidentification, a label will be affixed to each sample container in a manner as to prevent the label from becoming dislodged during transport which will contain the following information: „ Sample identification number, „ Name and signature of sample collector, „ Date and time of collection, „ Place of collection, „ Parameters requested, and „ Preservative. Appendix A Water Quality Monitoring Plan A 16 P:\Buncombe - 6447\65973 C&D Substantial Amdmt\Reports\Permit to Construct and Sub Amdmt\6 - Operation Plan\AppA - GW and SW Monitoring Plan\Appendix A.docx In addition the container itself should be labeled with the sample identification number, at a minimum, to allow for identification should the label fall off. 4.6 Quality Assurance/Quality Control The reliability and validity of the field and analytical laboratory data will be monitored as part of the QA/QC program used in the laboratory. Field duplicates and sample blanks will be collected to check sampling protocol and to account for any changes that occur after sampling. The QA/QC program will stipulate the use of standards, laboratory blanks, and duplicates for identification of matrix interferences. 4.6.1 Field Duplicates Field duplicates provide a measure of field and laboratory precision. Field duplicates will be collected from identical locations using proper sampling procedures. The duplicate samples will be collected at a frequency of one per day per sampling event. 4.6.2 Equipment Rinsate Blanks To evaluate the effectiveness of the decontamination procedures, equipment rinsate blanks will be collected. The sample will be collected by passing distilled water through the sampling equipment after decontamination has been completed. Equipment blanks will be collected at a minimum of one per day of groundwater sampling activities. 4.6.3 Trip Blanks A trip blank shall be prepared to account for any sample contamination that may occur during transport to and from the site. The sample will be prepared in the laboratory with deionized or distilled water and shall accompany the sample shipping container to the field. The trip blank shall remain unopened until receipt by the lab for analysis. One trip blank per sampling event will be collected. 5 References ASTM (American Society of Testing and Materials).

Page 3 T his guide gives you specific, easy to follow instructions for the safe and efficient usage of Landfill Service Corporation’s Posi-Shell® Cover System Advanced Formulation. For best results and to ensure safety, please follow the instructions care- fully. 1.0 Definition of Posi-Shell Cover System Advanced Formulation The Posi-Shell Cover System is a low-cost alternative to the conventional six inches of soil used as daily cover at most landfills. Posi-Shell Advanced Formulation is a noncombustible blend of materials providing a thin cover (approximately one-quarter inch) that hardens over the surface of the material to be covered, such as the working face of the landfill. Non-toxic, the stucco-like coating performs all functions of landfill daily and intermediate cover. Applied with a standard hydroseeding unit, this system provides increased landfill capacity while pro- viding a more environmentally effective cover system for the landfill. 1.1 Background and Concept Landfilled solid waste must be covered each day to control vectors, fires, odors, blowing litter, and scavenging. Cover material is generally defined as a six inch soil layer or other suitable material, or a combination of same, that is used to cover compacted solid waste in a landfill. The Posi-Shell Cover System Advanced Formulation is an alternative to traditional landfill daily cover materials. The coating is a spray-on slurry composed of water, Posi-Pak Type P-100, PSM-200 Setting Agent, and optional Portland cement that forms an approximately one- quarter-inch coating for various types of landfill cover. The Posi-Shell Cover System Advanced Formulation is designed for use by a landfill operator at the close of each operating day for compliance with cover regulations. The material meets and exceeds regulatory requirements for the control of landfill vectors, fires, odors, blowing litter, and scavenging. Posi-Shell Advanced Formulation (AF) provides cover ranging from 4 to 10 square feet per gallon of slurry. The coverage area is dependent upon the desired thickness and the actual texture of the covered surface. Application of the Posi-Shell AF is a one-man operation. 1.2 Environmental and Economic Benefits The Posi-Shell Cover System conserves natural resources. Additionally, use of the Posi-Shell Cover System conserves energy and improves air quality by eliminating the use of heavy earth-moving equipment for the transporting, laying, and reworking of daily soil cover. Traffic congestion to and from the landfill site, vehicle exhaust, and fugitive dust emissions are also reduced proportionately to the reduction of landfill soil hauling for daily cover. Soil, a valuable natural resource, is conserved by the Posi-Shell Cover System AF. In many areas, soil is an expensive natural resource that is in short supply. Use of the Posi-Shell Cover System AF can eliminate the waste of this precious commodity. The major benefit of the use of the Posi-Shell Cover System AF is the conservation of extremely valuable landfill capacity, commonly known as “air space”. Landfill air space is a valuable asset and the need to conserve capacity is paramount to achieve environmental and economic objectives for both landfill operators and regulatory agencies. Efficient use of air space today can directly translate into longer landfill life, decreased operating costs, and increased revenue generation. An increase in air space efficiency can delay or even eliminate the need for the siting and construction of new facilities that ultimately may have severe environmental and economic impacts. For comparison purposes using daily cover for a working face area of 5,000 square feet for a period of one year with Posi-Shell AF as op- posed to six inches of top soil will realize an air space savings of about 24,000 cubic yards. Use of Posi-Shell AF as opposed to soil will result in a direct increase in the amount of airspace available in a landfill. Landfill Service Corporation Page 4 1.3 Equipment The equipment used for the Posi-Shell Cover System AF consists of a standard hydroseeding unit, a towing unit, and a water source. The towing unit is used for moving the hydroseeding unit around the landfill site. If a nearby hydrant or other water source is not available, then a water trailer or truck is required. 1.4 Personnel One operator is required for the Posi-Shell Cover System AF. This operator must be capable of operating heavy equipment and be familiar with the mechanics of all equipment used. The operator will be trained by Landfill Service Corporation in the use of Posi-Shell AF. If preferred, a two man operation may be used to expedite coverage time. 1.5 Materials 1.5.1 Water Potable water, non-potable water and landfill leachate can be used as the liquid portion of the Posi-Shell Cover System AF. Use of leachate requires a site-specific regulatory approval to assure proper health and safety practices are implemented. Approximately 1,600 gallons of water is used for each 2000 gallon load of Posi-Shell AF. The water can either be supplied by a hydrant, pumped from a nearby pond, or brought to and stored adjacent to the hydroseeding unit by water truck or trailer. The sizing of the spe- cific water supply method should be adequate to ensure that the filling of the hydroseeding unit occurs within a few minutes’ time. As stated, leachate can be used as a water source if specific regulatory approval is obtained. It is not recommended that a high-strength leachate be used due to odor concerns and the added safety precautions required to assure worker safety. However, use of relatively dilute leachate is an effective method for reducing a portion of a landfill’s total leachate production. The inherent odor-neutralizing properties of Posi-Shell AF mitigate the potential odor problems of leachate when it is used as a water source. 1.5.2 Posi-Paks Posi-Paks are an important constituent of Posi-Shell AF and give the cover its fiber reinforced rigidity and weather resistance. Posi-Paks are lightweight, easy to handle, and ready to use. Posi-Pak is a specially designed plastic fiber with a proprietary finish that provides the rein- forcement matrix for the finished cover. Four Posi-Paks are used for each 2000 gallon load. See the back of this manual for a material safety data sheet for this material. 1.5.3 Dye Optional dyes can be added to the Posi-Shell AF mixture to create a soil-like brown coloring or a grass-like green coloring. 1.5.4 PSM 200 Setting Agent A proprietary blend of natural bentonite clay, synthetic polymers, and adhesives provide thickening, lubrication, and adhesion in the Posi- Shell AF mixture. See the back of this manual for a Material Safety Data Sheet for this material. 1.5.5 Portland Cement Optional Portland cement can be used as the cementitious mineral binder component of Posi-Shell AF. On average, approximately 4,000 lbs. of this material is used for each 2000 gallon Posi-Shell AF load. The Portland Cement further helps neutralize odors and contaminants found in leachate and enhances the durability of the Posi-Shell. Posi-Shell AF Usage Guide Page 5 2.0 Safety Posi-Shell AF is nonhazardous and is composed of nonhazardous materials. Certain safety measures are recommended during different aspects of Posi-Shell AF use. Follow safety procedures specific to your hydroseeding unit, towing unit, or other equipment used. 3.0 Operator Attire The operator should, at all times, wear appropriate protective clothing. Jewelry and loose fitting clothing should be avoided. Recom- mended protective clothing includes the following: • Safety glasses with side shields • Leather gloves • Industrial grade work coveralls • Leather steel-toed shoes • Dust particulate mask If leachate is being used as the liquid portion of the Posi-Shell AF mixture, protective clothing in accordance with site regulations should be worn. 4.0 Towing Units See table on page 11 for Posi-Shell AF total material weights. To determine the total load weight, add the Posi-Shell AF total material weight to the weight of your hydroseeding unit. Ensure that the towing unit and hitch arrangement are capable of handling the total of these weights. 5.0 Loading and Mixing Procedure It is important to add the Posi-Shell Advanced Formulation materials in the order specified. 5.1 Liquid Addition (Step 1) Before placing any dry material in the mixing tank, the tank must be filled with the appropriate amount of liquid (water or leachate). See chart on page 11. If your hydroseeding unit has a reserve water tank, fill at this time with clean water. It is not recommended to use leachate as the clean out water. All bags of material (Posi-Pak Type P-100, PSM-200 Setting Agent, Portland cement) can be loaded through the side rails of hydroseed- ing unit onto mixing deck from the ground. Ensure that they do not obstruct the ladder area. Never attempt to carry up or down lad- ders. To avoid back injuries, always use proper lifting practices when handling bags. Wet or frozen materials should not be used. 5.2 Posi-Pak Addition (Step 2) With mixer paddles of hydroseeding unit turning slowly open the Posi-Pak, Type P-100 bag and dump contents into inlet hopper (discard bag). Posi-Paks are designed such that the plas- tic covering may be torn away with the bare hands. If a knife is used take care not to drop into mixing tank. See chart on page 11 for Posi-Pak, Type P-100 quantities. Landfill Service Corporation Page 6 5.3 Optional Dye (Step 3) Various dyes are available for Posi-Shell Advanced Formulation to alter the color of the finished product to best suit the application. Most commonly used are brown and green. Brown and green dye is available in powder form and comes in dissolvable “Mix Ready” bags which can be placed directly in the mixing tank. Green is also available in liquid form that can be poured in the tank. 5.4 PSM-200 Setting Agent (Step 4) When handling PSM-200 Setting Agent or Portland cement a dust mask is recommended to prevent inhalation, and coveralls and gloves to prevent skin contact. Safety glasses should be worn to keep dust from entering the eyes. Should eyes or skin come in physical contact any Posi-Shell AF ingredients thoroughly rinse with water. With mixer paddles running at medium speed add PSM-200 Setting Agent material by cutting open bag and dumping contents into the mixing tank (discard bag). See chart on page 14 for quantities. Allow PSM-200 Setting Agent and Posi-Pak to mix at me- dium speed for about 5 minutes until a gravy-like consistency is achieved and no clumps are visible (see photo below at left). 5.5 Optional Portland Cement Addi- tion (Step 5) With mixer paddles still running at medium speed add Type I Portland cement material (regular Portland cement, NOT concrete.) by cutting open bag and dumping contents into the mixing tank (discard bag). See chart on page 11 for quantities. Posi-Shell AF material is now ready to be applied (see photo below at right). After Adding PSM-200 Setting Agent After Adding Portland Cement Powdered Dye Liquid Dye Posi-Shell AF Usage Guide Page 7 6.0 Transporting Close inlet hopper lid prior to transportation and leave mixer paddles turning at medium speed. 6.1 Cold Weather Transport To prevent freezing during extremely cold weather (below 20°F), with discharge gun attached to recirculation fitting, run pump in low-speed forward to circulate slurry from mixing tank, through pumping and discharge system, and back to mixing tank. 6.2 Traversing Slopes The proper procedure for traversing slopes is to approach the slope with machine parallel with fall line of slope. Machine should always be backed down the slope and towed up. Following this procedure eliminates any possibility of the machine “jack-knifing” around the towing unit. 7.0 Application of Posi-Shell AF Conventional end-of-day waste surface preparation and grooming are normally adequate prior to Posi-Shell AF application. A smoother surface will require less slurry due to reduced surface area. Also, the functional performance of the coating is enhanced by a smoother receiv- ing surface. Therefore, it may be desirable to spread available materials such as sludge, ash, or processed wastes at the end of the day to func- tion as surface leveling agents to economize on Posi-Shell AF slurry consumption. Each gallon of slurry will coat approximately 4 to 10 square feet depending on surface roughness and application thickness. Methods of application and the desired appearance of daily coatings are shown on the photographs which follow. In general, the operator should position the Applicator upwind, and should select the spray nozzle appropriate to the distance from the waste pile. A uniform coat- ing of approximately one-quarter-inch thickness will normally accomplish the daily cover functional criteria. In some cases, it will be neces- sary to spray a given area from two directions to compensate for “spray shadow” effects or wind dispersion. The most effective method of coverage will vary with each site, but generally, spraying the working face from the bottom of the waste slope, toward the top, is most effective. A minimal amount of “shadowing" occurs if applied in this manner. Application of Posi-Shell AF cover is not typically affected by weather conditions. Normal operations can be performed during windy, rainy, or cold weather conditions. During cold weather periods, the hydroseeding unit tank and pump must be drained at the end of the day to avoid freezing. It is desirable, but not necessary, to bring the machinery into a building for overnight storage. The application process is typically not affected by severe cold weather. When high winds are encountered, it may be necessary to position the hydroseeding unit in an upwind position. Since the hydroseeding unit pumps emit a high pressure stream of slurry, it is not generally affected by light winds; however, wind direction should always be consid- ered with respect to airborne dispersion of overspray. During light rains, Posi-Shell AF will not wash away and will retain its stucco consistency. However, during extremely heavy rains, some washing of the material may occur prior to its curing. During extremely cold weather, Posi-Shell AF will freeze before curing. After a thaw the material will cure. Cured Posi-Shell AF material typically can retain integrity up to one year or longer depending upon its initial application thickness.

By applying the material as a daily cover, typical landfill odors will be reduced by the thick layer of Posi-Shell that is applied. Additionally, if Portland Cement is used the calcium oxide (lime) applied to putrid waste further suppresses odors by sealing the outer face of the waste with an alkaline surface layer. Posi-Shell AF allows an opportunity for the optional addition of approved odor-masking agents where excessive odors warrant such action. 7.2 Vector Control Application of Posi-Shell AF to the working face of waste piles is an extremely effective vector deterrent. Shortly after the Posi-Shell AF coat- ing is applied, temperatures within the waste pile will increase due to initial aerobic and subsequent anaerobic decomposition. The Posi- Shell AF layer forms a seal that inhibits flies from laying additional larvae. Other vectors such as rodents and birds are discouraged by the Posi-Shell AF seal. Posi-Shell AF cover has proven effective in inhibiting the attraction of vectors to waste piles. 7.3 Scavenging General animal scavenging is reduced since the Posi-Shell Cover System AF seals in odors and hides the visible food source beneath the cov- ering shell. Scavenging by humans is inhibited by the complete visual coverage of the waste pile and by the viscid coating of slurry applied upon all available surface objects. 7.4 Litter Control Posi-Shell AF cover is highly effective for litter control. Due to the sticky consistency of the material, a shell is formed over the garbage which prevents litter from being blown away by high winds. A thin layer of Posi-Shell AF cover is recommended for preventing litter genera- tion. In extremely windy situations, Posi-Shell AF coating can be applied to waste as it is being unloaded from garbage trucks. This technique has been proven highly effective. 7.5 Fire Control Posi-Shell AF cover is an extremely effective fire control material. Independent laboratory testing of Posi-Shell AF by D-4982 method has certified that Posi-Shell AF is non-fuel contributing, non-smoke producing, and non-combustible. When an acetylene torch is applied di- rectly to the Posi-Shell AF cover, ignition of the Posi-Shell AF cover or underlying waste does not occur. In addition to the non-flammable characteristic of Posi-Shell AF cover, your hydroseeding unit can be used to fight landfill fires. Direct ap- plication of Posi-Shell AF material to an open flame will smother it. If a subterranean landfill fire occurs, Posi-Shell AF coating can be ap- plied to the waste pile’s surface and will form a fire smothering seal. Landfill Service Corporation Page 10 7.6 Additional Applications Posi-Shell AF cover fulfills the relevant performance criteria for various additional applications including erosion control, ditch lining, coat- ing of sludge piles, contaminated soil piles, compost piles and temporary waste piles and excavations of various types. If has been successfully applied to coal piles, salt piles, cement clinker piles and used at remediation sites to suppress volatile emissions. Posi-Shell AF may also be used as the tackifier in hydroseeding mixtures.

Experience and operator discretion will determine which nozzle to use in each situation. 7.8 Handling the Discharge Spray Boom Care must be taken to use the proper discharge nozzle in order to attain the desired spray range, as being too close to the surface will cause the Posi-Shell AF stream to overturn waste on contact. At long range distances the Posi-Shell AF stream will break up, causing the desired spray effect. At ranges under 75 ft. the medium or short nozzle should be used and are designed to spray in a wide ribbon pattern. Blockages may occur in nozzles due to foreign objects in the raw materials. Refer to Section 11.1 for procedure on removing foreign object from discharge nozzle. With the desired nozzle securely in place, firmly grasp discharge spray handle in one hand and point discharge nozzle in desired direction of spray. With the other hand move pump control lever to full speed forward and begin covering area. For desired spray effect operator may adjust pump/throttle speed. Never disconnect nozzles when pump is running. Never engage pump with discharge spray boom left unattended. Never put hands in front of discharge nozzles. Do not spray at or near other persons. Spray exits nozzle at a high velocity and could cause injury. Do not spray toward power lines, transformers or other high voltage conductors. Avoid spraying into wind. When unavoidable, be sure to keep direction of spray near to ground. Safety glasses should be worn during spraying operation. 7.9 Coverage of Large Area Coverage of a large area will require moving the hydroseeding unit to several spray locations. Inspect the area from several perspectives to ensure that the spray has covered all areas. 7.10 Thicker Coats Thicker coats may be applied by letting the first coat partially dry before recoating the area. Several thin applications provide a more durable shell than a single very thick application. Long Range for Distances of 75ft -150ft Medium Range for Distances of 25ft -75ft Short Range for Distances of 5ft -25ft Posi-Shell AF Usage Guide Page 13 8.0 Cleaning It is recommended that you clean the hydroseeding unit after each load. Due to the variety of hydroseeding units on the market a generic procedure for cleaning follows. Some steps may need to be altered to apply to your hydroseeding unit. 1. When all Posi-Shell AF is removed from mixing tank, immediately bring pump and mixer control levers to neutral position. Engine should remain at full throt- tle. 2. Open all inlet lids on hydroseeding unit. 3. Firmly grasp clean-off hose in one hand and turn on water. 4. With both hands on hose perform initial rinse down of all inlets and any resi- due visible in mixing tank. This process should take approximately one minute and use about 50-100 gallons of water depending on the size of the mixing tank. 5. Turn water off. 6. With a spray nozzle in place (to retain cam and groove gasket) run pump control lever full speed forward for 5 seconds. Return to neutral when complete. Re- peat with all nozzles used during application. 7. Close all inlet lids and bring mixer control lever to full speed reverse and allow to run for at least one minute. 8. Return mixer control lever to neutral then to full speed forward for at least one minute. 9. With mixer control lever in full speed forward, climb down ladder and remove drain cap and a l - low initial rinse water to completely drain. 10. Replace pump drain cap. 11. Return to deck of unit and move mixer control lever to neutral and repeat steps 2-9. During this secondary rinse make sure all external surfaces are thoroughly rinsed. A properly cleaned hydroseeding unit will remain free of any built-up product internally and exter- nally, and all decals and labels remain clearly readable. 9.0 Winter Care In extreme cold it is imperative that engines and hydraulic systems are thoroughly warmed before introducing a load. Refer to the opera- tions manual for your hydroseeding unit for proper winter usage and care. 9.1 Posi-Shell AF Winterizing Procedure 1. After cleanout, drain the mixing tank thoroughly. DO NOT REPLACE DRAIN CAP. 2. If your hydroseeding unit is equipped with a reserve water tank and/or pump, drain thoroughly. DO NOT REPLACE DRAIN CAPS. 3. Pour approximately one half gallon of anti-freeze into pump or tank and slowly run through pump and lines to prevent freezing. Landfill Service Corporation Page 14 10.0 Materials Storage All materials are inert, and can be stored on, or off, the boundaries of lined landfill cells. 10.1 Posi-Shell Material Storage 10.1.1 Posi-Paks Posi-Paks should be kept dry, particularly when freezing is possible. The Gaylord boxes are water-resistant, but not waterproof. Boxes can be easily covered with a tarp or plastic to keep the Posi-Paks dry. 10.1.2 PSM-200 Setting Agent PSM-200 Setting Agent should be kept dry. Stretch wrapped pallets can be easily covered with a tarp or plastic. 10.1.3 Optional Portland Cement & Dye Portland Cement & dye should be kept dry. Stretch wrapped pallets can be easily covered with a tarp or plastic. 11.0 Troubleshooting (may not apply to all hydroseeding units) 11.1 Removing Foreign Object from Discharge Nozzle 1. Immediately move pump control lever to neutral position. 2. Move pump control lever to slow speed reverse. 3. Run pump in reverse for 5 seconds to relieve pressure in discharge line. 4. Return pump control lever to neutral position. 5. Remove nozzle and clear obstruction. 6. Reconnect nozzle and continue spraying. 11.2 Removing Foreign Object from Mixing Tank 1. Move throttle, mixer, pump, control levers to slow/neutral position. 2. Shut engine off. 3. Move hydroseeding unit to area appropriate for dumping load. 4. Remove pump cleanout plug and allow load to drain. 5. Visually inspect pump for foreign object. Remove if found, replace plug and return to operations. 6. If object is not found in pump, remove exit pipe cleanout cap. 7. Inspect this section of pump for object. Remove if found, replace cap and pump cleanout plug and return to operations. 8. If object is not found in this section, remove two pipe couplers and removable section of tank exit pipe. 9. Visually inspect flange section of pump and mixing tank (flashlight may be necessary). Remove object if found, replace removable pipe and cleanout cap, pump cleanout plug, and return to operations. 10. If object is in mixing tank use appropriate length grapple through tank exit pipe. Posi-Shell AF Usage Guide Page 15 11.3 Clearing Clogged Mixing Tank 1. If Posi-Shell AF slurry has thickened in the mixing tank to the point that the mixer paddles will not turn, move mixer control lever to neutral. Trying to force mixer shaft back and forth at this point will only result in possible damage to the mixer shaft compo- nents. If the pump was not running, immediately connect the recirculation hose and move the pump control lever to slow speed forward (slightly above neutral). Slowly running the pump will prevent the Posi-Shell AF from setting up in the pump. If Posi-Shell AF is so thick that it is not flowing freely to pump, then the slurry must be liquefied at the mixing tank outlet to the pump in order to establish pump flow. 2. A reserve of 300-500 gallons of water should be available while mixing loads of Posi-Shell AF. In the event of a clogged mixing tank, water should immediately be introduced through the liquid inlets to the Posi-Shell AF mixture to thin the slurry and establish pump flow. By injecting water through a 2-3" diameter hose and directing the flow at the surface of the slurry it may be possible to loosen the product enough to free the mixing shaft. While trying to free the mixing shaft, gently move the mixer control lever from slow speed forward to slow speed reverse. Abrupt movements to full speed forward and full speed reverse could cause damage. 3. Use a slurry pump and water pick hose to loosen stiffened mixture. This can be attached on the spray tower in the same manner as a spray nozzle and used as a high-pressure, high-volume water pick which will cut the slurry away from the mixing shaft and liq- uefy it as it goes through the pump system. This spraying should be performed through the inlet hoppers. Excess slurry can be discharged out of the tank and new water introduced as required. Continue cutting away and liquefying with the water pick hose until mixer is free. Care should be taken as the water exits this hose at a high rate of speed. Also safety goggles and rain gear should be worn as splashing will occur. Immediately rinse any slurry off skin. 4. If the slurry will not flow through the pump, then water may be injected directly into pump drain and moved through the hy- droseeding unit’s pumping system and sprayed back into the mixing tank. To prevent cavitation of the pump, water must be in- jected at a rate equal or greater than the discharge rate. Once pump flow is established, then proceed with Step 3 above. 5. If the mixture is so hardened that the water pick will not cut it, move mixer and pump control levers to neutral and the throttle control lever to low, and shut off engine. Remove key from ignition and lock out control panel enclosure. Remove deck plates starting with right rear section. After removing all sections, thickened slurry will need to be removed from around mixing shaft using shovels and hoes. Rubber boots, goggles, gloves, and coveralls should be worn if entry into the tank is necessary. It may not be necessary to remove all of the slurry from the tank. First, simply free the mixing shaft and if the Posi-Shell AF is still soft, add water and after replacing deck plates, mix rapidly in tank to loosen and drain out the cleanout. Never allow mixed Posi-Shell AF to set in tank more than one hour. Landfill Service Corporation Page 16 11.4 Clearing Clogged Discharge Pipe/Hose 1. Immediately move pump control lever to neutral position. Move pump control lever to slow speed reverse. 2. Run pump in reverse for 10 seconds to relieve pressure in discharge line. 3. Return pump control lever to neutral position. 4. Disconnect discharge hose quick-connect from discharge elbow and allow discharge pipe and hose to drain. 5. To ensure that obstruction is not in pump and exit piping, move throttle and pump control levers to very slow speed forward for 5 seconds. If product is discharging at top of discharge elbow, obstruction is not in pump. 6. If pump and exit piping are clear, disconnect discharge hose from discharge pipe and visually inspect discharge hose for obstruction. Clear if found, reconnect hose and return to operations. 7. If discharge hose is clear, it will be necessary to snake out discharge piping. 8. When obstruction is found and cleared, reconnect discharge hose and return to operations. 11.5 Clearing Obstruction from Pump 1. Immediately move pump and throttle control levers to neutral position. 2. Shut engine off. 3. Move hydroseeding unit to area appropriate for dumping load. 4. Remove pump cleanout plug and allow load to drain. 5. Visually inspect pump for foreign object. Remove if found, replace plug and return to operations. 6. If object cannot be removed via pump cleanout, disassembly of stator will be required. See hydroseeding unit operations manual for procedure. 12.0 Contingency Soil Supply In the event that you are unable to apply Posi-Shell AF, the landfill operator should have a three-day supply of soil for daily cover material available on-site.

Landfill Service Corporation Page 32 MATERIAL SAFETY DATA SHEET MATERIAL: OSHA 29CFR 1910.1200 PORTLAND CEMENT DATE OF PREPARATION: MARCH 2006 SECTION I -- IDENTITY Distributor's Name and Address: Landfill Service Corporation 2183 Pennsylvania Avenue Apalachin, NY 13732 Emergency Telephone: (607) 625-3050 Chemical Name and Synonyms: Portland Cement Generic Name: Also known as hydraulic cement Trade Name: Portland Cement Type I, IA, II III, V SECTION II -- HAZARDOUS INGREDIENTS Posi-Shell AF Usage Guide Page 33 *Trace Constituents: Portland cement has a variable composition depending upon the cementitious products produced in the cement kiln. Small amounts of naturally occurring, but potentially harmful, chemical compounds might be detected during chemical analysis. These trace compounds might include free crystalline silica, potassium, and sodium compounds; heavy metals, including cadmium, chromium, nickel, and lead; and organic compounds. Other trace constituents may include calcium oxide (also known as free lime or quick lime). SECTION III -- PHYSICAL DATA Boiling Point (ºF) (Aqueous Portion): N/A Vapor Pressure (mm. Hg): N/A Vapor Density (Air=1): N/A Solubility in Water: Slight (0.1-1.0%) pH (in water): 12-13 Specific Gravity (H2O=1): 2.9-3.15 Evaporation Rate: N/A Appearance and Odor: Gray or white powder, no distinct odor SECTION IV -- CHEMICAL DATA N/A SECTION V -- FIRE AND EXPLOSION HAZARD DATA Portland cement is non-combustible and not explosive. Special firefighting procedures are not applicable. (Although Portland cement poses no fire-related hazards, a self-contained breathing apparatus is recommended to limit exposure to combustion products when fight- ing any fire.) Landfill Service Corporation Page 34 SECTION VI -- HEALTH HAZARD DATA Threshold Limit Value: N/A Effects of Overexposure: Acute: Wet cement on unprotected skin, whether direct or through saturated clothing, can cause severe, third-degree caustic burns. NOTE: Portland cement burns skin with little warning; discomfort or pain cannot be relied upon to alert a person to a hazardous skin exposure. The severity of the burn may not be detected until several hours after the dam- age begins. Dry Portland cement can produce mild irritation to severe burns of the eye; it can irritate the upper respiratory system. Chronic: Dry Portland cement can cause inflammation of the lining of the nose and the cornea. Repeated exposure to Portland cement may result in drying of the skin and may lead to thickening, cracking, or fissuring, of the skin. Hypersensitive individuals may develop an allergic dermatitis (possibly due to trace amounts of hexavalent chromium at less than 0.005%). This reaction may appear in several forms including a mild rash to severe skin ulcers. Persons already sensitized may react to their first contact with the product. Other persons may experience this effect after years of exposure to Portland cement products. While Portland cement typically has less than 0.2% crystalline silica, other additives to Portland cement and those components (e.g. aggregates) added to produce Portland cement concrete may significantly increase the amount of crystalline silica that is present. Exposure to respirable crystal- line silica without the use of a respirator can cause silicosis and may ag- gravate other lung conditions. Signs and Symptoms of Exposure: Burning sensation around moist tissue areas (i.e., eyes, nose, upper res- piratory system); painful burning on exposed skin that can develop with little warning. Exposure of sufficient duration to wet Portland cement can cause serious, potentially irreversible tissue (skin or eye) destruction in the form of chemical (caustic) burns, including third-degree burns. The same kind of destruction can occur if wet or moist areas of the body are exposed for sufficient duration to dry Portland cement. Do not allow wet Portland cement to get inside boots, shoes, or gloves, and do not allow wet, saturated clothing to remain against the skin. Posi-Shell AF Usage Guide Page 35 Emergency and First Aid Proce- dures: ● Irrigate eyes immediately and repeatedly with large amount of clean water for at least 15 minutes and get prompt medical attention. ● Wash exposed skin areas with pH-neutral soap and clean water. ● Apply sterile dressings; seek medical treatment in all cases of pro- longed exposure to wet Portland cement, Portland cement mixtures, liq- uids from fresh Portland cement products, or prolonged wet skin expo- sure to dry Portland cement. ● If ingested, consult a physician immediately. ● Do not induce vomiting. If conscious, have the victim drink plenty of water and call a physician immediately. ● In the event of inhalation, remove to fresh air. ● Seek medical attention if coughing and other symptoms do not sub- side. ● Inhalation of gross amounts of Portland cement requires immediate medical attention. SECTION VII -- REACTIVITY DATA Stability: Product is stable. Keep dry until used. Hazardous Polymerization: Will not occur. Incompatibility: Aluminum powder and other alkali and al- kaline earth elements will react in wet mor- tar or concrete, liberating hydrogen gas. Portland cement is highly alkaline and will react with acids to produce a violent, heat- generating reaction. Toxic gases or vapors may be given off, depending on the acid involved. Hazardous Decomposition Products: None known. SECTION VIII -- SPILL PROCEDURES Steps to be Taken if Material is Released or Spilled: Use dry cleanup methods that do not disperse the dust into the air. Avoid breathing the dust. Emergency procedures are not required. SECTION IX -- EXPOSURES OF CONCERN Medical Conditions Generally Ag- gravated by Exposure: Pre-existing skin conditions may be worsened. Silicosis may aggravate other chronic pulmonary conditions and may increase the risk of pulmo- nary tuberculosis infection. Landfill Service Corporation Page 36 Chemical Listed as Carcinogenic or Potential Carcinogen: Portland cements are not considered carcinogenic. However, the Inter- national Agency for Research on Cancer (IARC) has determined, primar- ily through animal studies, that silica is a known human carcinogen. The National Toxicology Program (NTP) has characterized respirable quartz silica as reasonably anticipated to be a carcinogen. OSHA does not regulate silica as a carcinogen. SECTION X -- HANDLING AND USE PRECAUTIONS Portland cement should only be used by knowledgeable persons. While the information provided in the ma- terial safety data sheet is believed to provide a useful summary of the hazards of Portland cement, as it is commonly used, the sheet cannot anticipate and provide all of the information that might be needed in every situation. Inexperienced product users should obtain proper training before using this product. A key to using the product safely requires the user to recognize that Portland cement chemically reacts with water, and that some of the intermediate products of this reaction (that is, those present while a Portland cement product is "setting") pose a more severe hazard than does Portland cement itself. These hazards include potential injuries to eyes and skin. The data furnished in this sheet do not address hazards that may be posed by other materials mixed with Portland cement to produce Portland cement products. Users should review other relevant material safety data sheets before working with this Portland cement or with Portland cement products, including, for exam- ple, Portland cement concrete. SECTION XI -- INDUSTRIAL HYGIENE CONTROL MEASURES Ventilation Requirements: Local exhaust can be used to control airborne dust levels. Respiratory Protection: Avoid actions that cause dust to become airborne. Use local or general ventilation to control exposures below applicable exposure limits. Use NIOSH/MSHA-approved (under 30 CFR 11) or NIOSH-approved (under 42 CFR 84) respirators in poorly ventilated areas, or if an applica- ble exposure limit is exceeded, or when dust causes discomfort or irrita- tion. (Advisory: Respirators and filters purchased after July 10, 1998, must be certified under 42 CFR 84.) Eye Protection: When engaged in activities where Portland cement dust or wet Portland cement or concrete could contact the eye, wear goggles or safety glasses with side shields. In extremely dusty environments and unpre- dictable environments, wear unvented or indirectly vented goggles to avoid eye irritation or injury. Contact lenses should not be worn when working with Portland cement or wet Portland cement products. Posi-Shell AF Usage Guide Page 37 Skin Protection: Prevention is essential to avoiding potentially severe skin injury. Avoid contact with unhardened (wet) Portland cement products. If contact oc- curs, promptly wash affected area with soap and water. Do Not Allow Wet Portland Cement to Get Inside Boots, Shoes, or Gloves; and Do Not Allow Wet, Saturated Clothing to Remain Against the Skin. Do not rely on barrier creams. Barrier creams should not be used in place of gloves. Use impervious, abrasion- and alkali-resistant gloves, boots, and protective clothing to protect the skin from prolonged contact with wet Portland cement in plastic concrete, mortar, or slurries. SECTION XII -- SPECIAL PRECAUTIONS Work/Hygienic Practices: ● Periodically wash areas contacted by dry Portland cement, or by wet Portland cement, or concrete fluids with a pH neutral soap and clean, uncontaminated water. ● Wash again at the end of the work. ● If irritation occurs, immediately wash the affected area and seek treat- ment. ● If clothing becomes saturated with wet Portland cement or concrete, it should be removed and replaced with clean, dry clothing. ● Follow listed precautions as appropriate, during repair or maintenance work on contaminated equipment.
