The approximately 158 acre facility is located approximately 6 miles east of High Point, in Guilford County. Area development is a mix of agricultural, industrial/commercial and landfill use. In general, development in the area is primarily along the main roads. The site and monitoring locations are shown on Figure 1. 1.2.1 Geology The WI High Point C&D Landfill is located within the Piedmont Physiographic Province of North Carolina, which is characterized by moderately rolling valleys and ridges. The Geologic Map of North Carolina (USGS, 1985) indicates that the site lies within the Carolina Slate Belt; Late Proterozoic to Cambrian age volcanic and sedimentary rock metamorphosed to lower greenshist facies with multiple intrusions. The site is underlain by white to gray, fine to coarse grained, granitic rock. DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 4 1.2.2 Hydrogeology The hydrogeology at this site has been investigated using, groundwater monitoring wells and aquifer slug tests. Groundwater flows primarily southwest, towards Richland Creek and its tributaries, with additional flow south and west. Richland Creek is approximately 1300 feet from the facility boundary and flows into Deep River. The uppermost aquifer is saprolite, partially weathered rock (PWR) along with granitic bedrock. Groundwater occurs from approximately ten feet below grade or less in the downgradient wells near the Richland Creek tributaries to twenty-five feet below grade upgradient of the waste area. Locally, the C&D site is bounded Richland Creek and its tributaries to the west and south. The average estimated horizontal hydraulic gradient across the site is approximately 8.06 ft/yr. Effective porosities calculated from the Phase 2 Design Study ranged from 13 to 28 percent. Laboratory derived permeabilies for those same locations ranged from 5.8 x 10-5 to 7.9 x 10-4 cm/sec2. Three well clusters were used to determine vertical gradient, MW-4S/D, P-26S/D and P-30S/D. Strong upward gradients were calculated at the MW-4S/D location, indicating discharge at this location. P-26S/D exhibited a downward gradient suggesting recharge as expected on the topographic high. Vertical gradient for P-30S/D was slightly downward, consistent with transition area hydrology. This Water Quality Monitoring Plan (WQMP) has been prepared to meet the field sampling and laboratory analysis requirements of ongoing monitoring at the site. The WQMP details field and laboratory protocols that must be followed to meet the data objectives of semi-annual groundwater monitoring. 2 From Golder Design Hydrogeologic Report, Phase 2 Expansion. (Revised August 2008). DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 5 2.0 MONITORING PROGRAM This Water Quality Monitoring Plan section addresses individual monitoring program components. At a minimum, WI High Point, LLC will monitor the groundwater quality on a semi-annual basis. 2.1 Monitoring Network and Analytical Parameters Historical water level data indicates that groundwater is flowing generally south to southwest towards a tributary of Richland Creek. There are ten existing well locations and four surface water points for the C&D landfill monitoring network. Three monitoring wells, MW-9, AMW-1 and AMW-2, are proposed for addition to the monitoring network. MW-9 is proposed to monitor the groundwater flowing south from the Phase 3 area. Due to VOC detections in samples collected from MW-2 and MW-6 the assessment monitoring wells AMW-1 and AMW-2 will be installed slightly downgradient to these locations. Well construction details are provided in Table 1 and well construction records are presented in Appendix A. The proposed monitoring network for the site is shown on Figure 1 and summarized in the table below.

Appendix I, Field and C&D parameters are listed in Table 2. 2. MW-1 and MW-2 are in Appendix II monitoring for 2-years per the December 7, 2015 letter from Golder Associates NC to Ms. Jackie Drummond. After 2-years water quality will be re-evaluated. A work plan DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 6 approval letter was issued to Mr. Seth Heath issued January 28, 2016. [DIN 25551] 3. Proposed monitoring well 4. Proposed in the Assessment Monitoring Notification and Work Plan Addendum letter from Golder Associates to Ms. Jackie Drummond, October 21, 2016; approved by NCDEQ October 31, 2016 (DIN 26956). This monitoring system is adequate to detect any releases from the landfill unit. 2.2 Groundwater Sample Collection Details regarding the procedures and equipment required to perform groundwater field measurements and sampling from monitoring wells during each monitoring event are presented in this section. Where possible, work will proceed from the upgradient (background) wells to downgradient (compliance) wells. 2.2.1 Guidance Documents Sampling, analysis, and submittals will be performed in accordance with this plan and the following guidance documents: 1. Groundwater, Surface Water and Soil Sampling for Landfills - NCDENR Guidance updated April 2008. 2. October 27, 2006 Memo from NCDENR entitled "New Guidelines for Electronic Submittal of Environmental Monitoring Data." 3. February 23, 2007 Memo from NCDENR entitled Addendum to October 27, 2006, North Carolina Solid Waste Section Memorandum Regarding New Guidelines for Electronic Submittal of Environmental Data. 4. October 16, 2007 Memo from NCDENR entitled Environmental Monitoring Data for North Carolina Solid Waste Management Facilities. 2.2.2 Fuel Powered Equipment Monitoring wells at WI High Point Landfill have dedicated bladder pumps; therefore fuel-powered equipment is not required for routine groundwater sampling. In the event, fuel-powered equipment, such as generators for additional pumps is needed, it must be situated away and downwind from site activities (i.e. purging and sampling). If field conditions prevent such placement, then the fuel source must be placed DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 7 as far away as possible from the sampling activities. The sampling conditions must be described in detail in the field notes. If fuel must be handled, it should be done the day before sampling. Effort should be made to avoid handling fuels on the day of sampling. If fuels must be dispensed during sampling activities, dispense fuel downwind and well away from any sampling locations. Wear gloves while working with fuel and dispose of the gloves away from sampling activities. Wash hands thoroughly after handling any fuels. 2.2.3 Equipment Decontamination Dedicated bladder pumps are used at WI High Point, however, non- dedicated equipment that will come in contact with the well casing and water will be decontaminated between wells. The procedure for decontaminating non-dedicated equipment is as follows: 1. Don new powder-free surgical gloves. 2. Clean item with tap water and phosphate-free laboratory detergent (Liqui-Nox or equivalent), using a brush if necessary to remove particulate matter and surface films. 3. Rinse thoroughly with pesticide grade isopropanol and allow to air dry. 4. Rinse with organic-free water (Milli-Q water or other ultra- pure water) and allow to air dry. 5. Wrap with commercial-grade aluminum foil, if necessary, to prevent contamination of equipment during storage or transport. Liqui-Nox detergent solutions will be stored in a clearly marked High Density Polyethylene (HDPE) or Polypropylene (PP) container. Containers for pesticide-grade isopropanol will be made of inert materials such as Teflon, stainless steel, or glass. Sampling will be planned and conducted in such a way as to minimize the need for decontamination in the field by using dedicated sampling equipment; new disposable Teflon bailers may be used as needed. Unclean equipment will be separated from clean equipment during field activities. Clean equipment will remain in the manufacturer's packaging until use, or will be wrapped in commercial-grade aluminum foil or untreated butcher paper. DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 8 2.2.4 Water Level Measurements 2.2.4.1 Static Water Levels Static water level and depth to the well bottom will be measured in each well prior to any purging or sampling activities. Static water level and well depth measurements are necessary to calculate the stagnant water volume in the well prior to purging. Additionally, these measurements provide a field check on well integrity, degree of siltation, and are used to prepare potentiometric maps, calculate aquifer flow velocities, and monitor changes in site hydrogeologic conditions. Groundwater depths will be measured to a vertical accuracy of 0.01 feet relative to established wellhead elevations. Each well will have a permanent, easily identified reference point on the well riser lip from which water level readings will be measured. The reference point elevation will be established by a Registered Land Surveyor. 2.2.4.2 Contamination Prevention After opening each well, new, powder-free, surgical gloves will be donned. Appropriate procedure will be followed during measurement activities to minimize the potential for soils, decontamination supplies, precipitation, and/or other potential contaminants from entering the well or contacting clean equipment. 2.2.4.3 Equipment An electronic water level indicator will be used to measure depth to groundwater in each well and/or piezometer. The electronic water level indicator will be constructed of inert materials, such as stainless steel and Teflon. Between each well, the device will be thoroughly decontaminated by washing with non-phosphate (Liqui-Nox) soap and rinsing with organic-free water to prevent cross contamination from one well to another. The following measurements and observations will be recorded in a field book prior to sample collection:  Depth to static water level and well bottom (to the nearest 0.01 foot);  Water column height in the riser (based on measured well depth); DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 9  Wellhead protective casing, base pad and riser condition; and  Changes in well and surrounding conditions. Section 5.0 presents a detailed description for collected field notes. 2.2.5 Monitoring Well Evacuations Water accumulated in each well may be stagnant and unrepresentative of surrounding aquifer conditions and therefore must be removed to insure that fresh formation water is sampled. The standing water in the well casing will be purged following recording the static water level measurement, unless low-flow sampling techniques are used. Monitoring well evacuation should be performed in upgradient wells first, and by systematically moving to downgradient well locations. 2.2.5.1 Contamination Prevention New, powder-free, surgical gloves will be donned for well purging and sampling activities and whenever handling decontaminated field equipment. Appropriate measures will be executed during measurement, purging, and sampling activities to minimize the potential for surface soils, decontaminated supplies, precipitation, and/or other potential contaminants from entering the well or contacting clean equipment. 2.2.5.2 Calculations The standing water volume in the well riser and screen will be calculated immediately before well evacuation during each monitoring event (if standard purging techniques are used). A standing water volume will be calculated for each well using measured static water level, well depth and well casing diameter according to the following equation: V = (TD - SWL) x C Where: V = One well volume (gallons) TD = Total depth of the well (in feet) SWL = Static water level (in feet) C = Volume constant for well diameter (gallons/foot) C = 0.163 gal/ft for two-inch wells. C = 0.653 gal/ft for four-inch wells.

Bailers – Where bailers are used, new, disposable bailers with either double or bottom check-valves will be used to purge each well. Disposable purge bailers will be constructed of fluorocarbon resin (Teflon) or inert plastic suitable for the well and ground conditions. Each bailer will be factory-clean and remain sealed in a plastic sleeve until use. A new Teflon-coated stainless steel, inert mono-filament line or nylon cord will be used for each well to retrieve the bailers. Where bailers are used, a minimum of three well volumes will be purged unless the well runs dry. Low Flow Pumps – Low flow pumps are typically used at this site for groundwater sample collection. Monitoring wells may be purged and sampled using the low-flow sampling method in accordance with the Solid Waste Section Guidelines for Groundwater, Soil, and Surface Water Sampling (NCDENR, 2008). Obtain depth-to-water measurements using an electronic water level indicator capable of recording the depth to an accuracy of 0.01 foot. Determine if the water table is located within the screened interval of the well. If the water table is not within the screened interval, the drawdown amount that can be achieved before the screen is intersected will be calculated. If the water table is within the screened interval, total drawdown should not exceed 1 foot to minimize the amount of aeration and turbidity. If the water table is above the top of the screened interval, the drawdown amount should be minimized to keep the screen from being exposed. If the purging equipment is non-dedicated, the equipment will be lowered into the well, using care to minimize the disturbance to the water column. If conditions (i.e., water column height and well yield) allow, the pump will be placed in the uppermost portion of the water column (minimum of 18 inches of pump submergence is recommended). The minimum volume/time period for obtaining independent Water Quality Parameter Measurements (WQPM) will be determined. The minimum volume/time period is determined based on the stabilized flow rate and the amount of volume in the DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 11 pump and the discharge tubing (alternatively, the volume of a direct read flow-cell can be used, provided it is greater than the calculated volume of the pump and discharge tubing). The bladder pump volume should be obtained from the manufacturer. Volume from the discharge tubing is as follows: 3/8-inch inside diameter tubing: 20 milliliters per foot 1/4-inch inside diameter tubing: 10 milliliters per foot 3/16-inch inside diameter tubing: 5 milliliters per foot Once the flow-cell or the pump and discharge tubing volume has been calculated, the well purge will begin. The flow rate should be based on historical data for that well (if available) and should not exceed 500 milliliters per minute. The initial WQPM should be recorded and the flow rate adjusted until drawdown in the well stabilizes. Water levels should be measured periodically to ensure a stabilized water level is maintained. The water level should not fall within 1 foot of the top of the well screen. If the purge rate has been reduced to 100 milliliters or less and the head level in the well continues to decline, the required water samples should be collected following stabilization of the WQPM, based on the criteria presented below. If neither the head level nor the WQPM stabilize, a passive sample should be collected. Passive sampling is defined as sampling before WQMP have stabilized if the well yield is low enough that the well will purge dry at the lowest possible purge rate (generally 100 milliliters per minute or less). WQPM stabilization is defined as follows: pH (+/- 0.2 S.U.), conductance (+/- 5% of reading), temperature (+/- 10% of reading or 0.2oC). Dissolved oxygen (DO) [+/- 20% of reading or 0.2 mg/L (whichever is greater)] and oxidation reduction potential (ORP) should also fall within +/- 10mV of reading; however, they are not required parameters but may also be measured. At a minimum, turbidity measurements should be recorded at the beginning of purging, following the stabilization of the WQPM, and following sample collection. The optimal turbidity range for micropurging is 25 Nephelometric Turbidity Units (NTU) or less. Turbidity measurements above 25 NTU are generally indicative of an excessive purge rate or natural conditions related to excessive fines in the aquifer matrix. WQPM stabilization should occur in most wells within five to six rounds of measurements. If stabilization does not occur following the removal of a purge volume equal to three well volumes, a passive sample will be collected. DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 12 Direct-read equipment used at each well will be calibrated in the field according to the manufacturer’s specifications prior to each day’s use and checked, at a minimum, at the end of each sampling day. Calibration information should be documented in the instrument’s calibration logbook and the field book. Each well is to be sampled immediately following stabilization of the WQPM. The sampling flow rate must be maintained at a rate that is less than or equal to the purging rate. For volatile organic compounds, lower sampling rates (100 - 200 milliliters/minute) should be used. Final field parameter readings should be recorded prior to and after sampling. Grundfos Redi-Flo Pumps – Where Redi-Flo pumps are used, the same low flow techniques for sampling will be used. Please see above for detailed summary of purging/sampling techniques. 2.2.5.4 Purge Rate Wells will be purged at a rate that will not cause recharge water to be excessively agitated or cascade through the screen; minimizing disturbance to the well sidewalls and bottom, which could result in silt and fine particulate matter suspension. The water volume purged from each well, and the relative recharge rate will be documented in sampling field notes. Wells which have very low recharge rates will be purged once until dry. Damaged, dry, or low yielding and high turbidity wells will be documented for reconsideration before the next sampling event. 2.2.5.5 Purge Water Disposal Purge water will be managed to prevent possible soil and surface water contamination. Well site management options may include temporary containment and disposal as leachate or portable activated carbon filtration if warranted by field characteristics. 2.2.5.6 Non-Dedicated Equipment Durable, non-dedicated equipment that is lowered into the well or which may come in contact with the water samples will be thoroughly decontaminated before each use. Equipment will be disassembled to the degree practical, washed with (non- phosphate) soapy potable tap water, and triple rinsed using de- ionized water. Detailed equipment decontamination procedures are detailed in Section 2.2.3.

Samples should be collected from the least contaminated location(s) first, followed by locations of increasing contamination across the site. Prior to sample collection, sample labels should be properly filled-out with permanent, waterproof ink. At a minimum, the label should identify the sample with the following information:  Site Name;  Sample Location or Well Number;  Collection Date and Time;  Analysis Required;  Sampler's Initials;  Preservative Used (if any); and  Other Pertinent Information as Necessary. Affix a label with the written information to the sample bottle prior to sampling. Sampling will occur within 24-hours of the purging of each well and as soon after well recovery as possible. Wells which fail to recharge or produce an adequate sample volume within 24 hours of purging will not be sampled. 2.2.6.1 Field Parameters Field measurements for temperature, pH, and specific conductance will be recorded immediately prior to sampling each monitoring point. For low-flow sampling, dissolved oxygen (DO) and oxidation reduction potential (ORP) shall also be collected. Additionally, turbidity measurements should be collected for detected metals evaluation. The field test specimens will be collected with the sampling bailer and placed in a clean, non- conductive glass or plastic container for observation. Temperature, pH, conductivity and turbidity meter calibration will be performed according to the manufacturers' specifications and will be consistent with Test Methods for Evaluating Solid Waste - Physical/Chemical Methods (SW-846). A pocket thermometer and litmus paper will be available in case of meter malfunction.

Dedicated bladder pumps are installed in the groundwater monitoring wells and low flow purging/sampling is most commonly utilized at the WI High Point Facility. Teflon Bailers – Where bailers are used, each well will be sampled using a new, factory-cleaned, disposable Teflon bailer with bottom check-valve and sample discharge mechanism. A new segment of Teflon-coated stainless steel wire, inert mono- filament line or nylon cord will be used to lower and retrieve each bailer. The bailer will be lowered into each well to the point of groundwater contact and then allowed to fill as it sinks below the water table. Bottom contact will be avoided, preventing suspended sediment in the samples. The bailer will be retrieved and emptied in a manner which minimizes sample agitation. Low Flow Pumps – Following purging with the low flow pump systems, samples may be collected immediately from the pumping system. Samples are to be collected in the order outlined in Section 2.2.6.4. Redi-Flo Pumps - Following purging three well volumes of water, samples may be collected from the Redi-Flo pumps. Samples will be collected in the order outlined in Section 2.2.6.4. 2.2.6.3 Sample Transference Samples will be transferred directly from the Teflon bailer or pump discharge tubing into a sample container that has been specifically prepared for the preservation and storage of compatible parameters. A bottom emptying device provided will be used to transfer samples from the bailer to sample container. The generation air bubbles and sample agitation will be minimized during bailer discharge. DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 15 2.2.6.4 Sample Collection Order Groundwater samples will be collected and contained in the order of volatilization sensitivity. Whenever possible the following sampling order will be observed:  Volatile Organics and Volatile Inorganics;  Extractable Organics, Petroleum Hydrocarbons, Aggregate Organics, and Oil and Grease;  Total Metals;  Inorganic Nonmetallics, Physical and Aggregate Properties, and Biologicals;  Microbiological  Wet Chemistry; and  Temperature, pH, DO, ORP, Conductivity, and Turbidity Measurements. Note: If the pump used to collect groundwater samples is not suitable to collect volatile or extractable organics then collect all other parameters and withdraw the pump and tubing. Then collect the volatile and extractable organics. Samples will be collected and analyzed in an unfiltered state during sampling events. Samples for dissolved metal analysis, if subsequently required, will be prepared by field filtration using a disposable 0.45 micron filter cartridge specifically manufactured for this purpose. 2.2.6.5 Decontamination Reusable sampling equipment including water level probes, water quality meters, interface probes, and filtering pumps which might contact aquifer water or samples will be thoroughly decontaminated between wells by washing with non-phosphate soapy, de-ionized water and rinsing with isopropanol and organic- free water (MilliQ or equivalent). Equipment decontamination procedures are detailed in Section 2.2.3. DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 16 2.2.6.6 Sample Preservation Following sampling at each location, the sample bottles will be placed in Ziploc bags inside a cooler with ice for preservation. 2.2.6.7 Field Quality Assurance Equipment and trip blanks will be prepared, handled, and analyzed as groundwater samples to ensure cross-contamination has not occurred. One set of trip blanks, will be prepared before leaving the laboratory to ensure that the sample containers or handling processes have not affected the quality of the samples. One set of equipment blanks will be created in the field at the time of sampling to ensure that the field conditions, equipment, and handling during sampling collection have not affected sample quality. This sample will be collected using the same equipment utilized for well sampling. A duplicate groundwater sample may be collected from a single well to check laboratory accuracy. Blanks and duplicate containers, preservatives, handling, and transport procedures for surface water samples will be identical to those noted for groundwater samples. Blank samples are discussed in detail in Section 3.1. 2.2.6.8 Sample Containers Sample containers will be provided by the laboratory for each sampling event. Containers must be either new, factory-certified analytically clean by the manufacturer, or cleaned by the laboratory prior to shipment for sampling. Laboratory cleaning methods will be based on the bottle type and analyte of interest. Metal containers are thoroughly washed with non-phosphate detergent and tap water, and rinsed with (1:1) nitric acid, tap water, (1:1) hydrochloric acid, tap water, and non-organic water, in that order. Organic sample containers are thoroughly washed with non-phosphate detergent in hot water and rinsed with tap water, distilled water, acetone, and pesticide quality hexane, in that order. Other sample containers are thoroughly washed with non-phosphate detergent and tap water, rinsed with tap water, and rinsed with non-organic water. The laboratory will provide proper preservatives in the sample containers prior to shipment (Section 4.0). 2.3 Surface Water Sample Collection This section presents the procedures and equipment required to perform surface water field measurements and sampling from springs, streams and ponds during each monitoring event. DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 17 2.3.1 Surface Water Level Observations Surface water quality analyses are particularly sensitive to site hydrologic conditions and recent precipitation events. Water levels may fluctuate significantly in comparison to the groundwater table and may result in either diluting or increasing contaminant loadings. Recent weather and sampling station conditions should be considered when scheduling the sampling event and interpreting the surface water data. 2.3.1.1 Monitoring Conditions Surface water level and sampling station conditions should be observed and recorded during each sampling event if warranted by site conditions. Surface water observations will include the flood stage in streams, seasonal base flow conditions, and confirm location and timing for meaningful surface water quality sampling. The following objective observations will be recorded in the field book prior to sample collection:  Relative stream water level;  Surface water clarity; and  Changes in surface monitoring station conditions and surroundings. 2.3.1.2 Sampling Station Modifications Modifications to surface water sampling station conditions may be required prior to each sampling event. These modifications may include surface and submerged debris removal, slightly deepening the station to allow sample container immersion, or channeling/piping to consolidate local discharge. When modifications are required, sufficient time will be allowed for settlement of suspended solids between the disturbance and sample collection. A minimum a settling period of four hours prior to sampling will be observed. 2.3.2 Sample Collection 2.3.2.1 Collection Procedure Surface water samples will be obtained from areas with minimal turbulence and aeration. Samples will only be collected if flowing water is observed during the sampling event. New, non- powdered, surgical gloves will be donned prior to sample collection. The following procedure will be implemented regarding surface water sampling: DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 18 1. Put on new, non-powdered, surgical gloves. 2. Hold the bottle by the bottom with one hand, and with the other, remove the cap. 3. Push the sample container slowly into the water and tilt up toward the current to fill. A water depth of six inches is generally satisfactory. Breaching the surface or losing sample preservatives while filling the container will be avoided. 4. If there is little current movement, the container should be moved slowly, in a lateral, side to side direction, with the container mouth pointing upstream. Surface water samples will be collected from surface water monitoring points shown on Figure 1. Samples will be collected directly from the station in the container that has been prepared for the preservation and storage of compatible parameters. Samples will be collected in a manner that assures minimum agitation. 2.3.2.2 Field Parameters Temperature, pH, specific conductivity, and turbidity will be measured at the start of surface water sampling, as a record of field conditions and a check on the water sample stability over time. Prior to sampling, temperature, pH, conductivity, and turbidity meter calibration will be completed according to the manufacturers' specifications and consistent with Test Methods for Evaluating Solid Waste - Physical/Chemical Methods (SW-846). 2.3.2.3 Sample Collection Order Surface water samples will be collected in the order of volatilization sensitivity. When collected, the following sampling order will be observed:  Volatile Organics and Volatile Inorganics;  Extractable Organics, Petroleum Hydrocarbons, Aggregate Organics and Oil and Grease;  Total Metals;  Inorganic Nonmetallics, Physical /Aggregate Properties;  Wet Chemistry; and  Temperature, pH, DO, ORP, Conductivity, and Turbidity Measurements. DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 19 Samples will be collected and analyzed in an unfiltered state during sampling events. Samples for dissolved metal analysis, if subsequently required, will be prepared by field filtration using a decontaminated peristaltic pump and a disposable 0.45 micron filter cartridge specifically manufactured for this purpose. 2.3.2.4 Decontamination Field meters which might contact surface water samples will be thoroughly decontaminated between stations by washing with non-phosphate soapy, de-ionized water and rinsed with isopropanol and organic-free water (MilliQ or equivalent). Detailed equipment decontamination procedures are detailed in Section 2.2.3. 2.3.2.5 Sample Preservation Following sampling at each location, the sample bottles will be placed in Ziploc bags inside a cooler with ice for preservation. 2.3.2.6 Field Quality Assurance If needed, equipment and trip blanks will be prepared, handled, and analyzed in the same manner as blanks for groundwater samples (Section 2.2.6.7). Samples will be collected using the same equipment utilized for well sampling. Duplicate samples will not be collected for surface water samples. Blanks and duplicate containers, preservatives, handling, and transport procedures for surface water samples will be identical to those noted for groundwater samples. Blank samples are discussed in detail in Section 3.1. 2.3.2.7 Sample Containers Sample containers will be prepared and provided by the laboratory for each surface water sampling event. Each container's preparation and preservatives will be the same as those utilized for groundwater sampling and addressed previously in Section 2.2.6.8. DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 20 3.0 FIELD QA/QC PROGRAM Field Quality Assurance/Quality Control (QA/QC) requires the routine collection and analysis of blank samples to verify that the handling process has not affected sample quality. Contaminants reported in blank samples could be attributed to: 1. Interaction between the sample and the container; 2. Contaminated source water; and/or 3. A handling procedure that altered the sample. 3.1 Blank Samples 3.1.1 Trip Blanks The laboratory will prepare a trip blank by filling each sample bottle type with laboratory grade distilled or deionized water. Trip blanks will be placed in bottles of the specific type required for the analyzed parameters, bottle packs will be specifically assembled by the laboratory for each sampling event. Trip blanks will be packaged by the laboratory prior to the sampling event and transported with the empty bottle packs. These bottles return to the laboratory in an untampered state. The trip blanks will be analyzed for volatile and purgeable organics only. 3.1.2 Equipment Blanks Where wells are sampled with non-dedicated equipment, equipment blank samples shall be collected at a rate of one sample per day. To collect an equipment blank, a bailer shall be filled with non-organic water (Milli-Q or equivalent). Handling the bailer in a manner identical to well sampling, the water is to be transferred into the sample collection jars for the equipment blanks. These samples are packed in the field and sent to the laboratory with the other samples. 3.1.3 Field Blanks To collect a field blank, deionized water from the lab or non-organic (Milli-Q or equivalent) water will be poured at the sampling location into laboratory provided sample collection jars. These samples are packed and sent to the laboratory with the other samples. 3.2 Blank Concentrations The contaminant concentration levels found in any blank samples will be reported but will not be used to correct the groundwater data. In the event that elevated parameter concentrations are found in a blank, the analysis will be flagged for future evaluation and possible re-sampling. DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 21 3.3 Field Instruments Field instruments utilized to measure groundwater characteristics will be calibrated prior to entering the field, and recalibrated in the field as required, to insure accurate sample measurements. The specific conductivity and pH meter will be recalibrated utilizing two prepared solutions of known pH concentration in the range of anticipated values (between 4 and 10). A permanent thermometer, calibrated against a National Bureau of Standards Certified thermometer, will be used for temperature meter calibration. Other field equipment should be calibrated at least daily using the manufacturer's recommended specifications. DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 22 4.0 SAMPLE PRESERVATION AND SHIPMENT Sample preservation, shipment, and Chain-of-Custody procedures to be observed between sampling and laboratory analysis are presented in the following sections. 4.1 Sample Preservation Pre-measured chemical preservatives will be provided by the analytical laboratory. Hydrochloric acid will be used as a chemical stabilizer and preservative for volatile and purgeable organic specimens. Nitric acid will be used as the preservative for samples for inorganic metals analysis. 4.2 Storage/Transport Conditions Proper storage and transport conditions must be maintained to preserve the sample integrity between collection and analysis. Ice and chemical cold packs will be used to cool and preserve samples, as directed by the analytical laboratory. Samples will be maintained at a maximum temperature of 4o C. Dry ice is not to be used. Samples will be packed and/or wrapped in plastic bubble wrap to inhibit breakage or accidental spills. Chain-of-Custody control documents will be placed in a waterproof pouch and sealed inside the cooler with the samples for shipping. Tape and/or custody seals will be placed on the outside of the shipping coolers, in a manner to prevent and detect sample tampering. 4.3 Sample Delivery Samples shall be delivered to the analytical laboratory within a reasonable period of time in person or using an overnight delivery service to insure hold times are not exceeded. If samples are not shipped the same day, the ice used to keep the samples cool will be replenished to maintain the required maximum temperature of 4o C. Shipment and sample receipt will be coordinated with the laboratory. Do NOT store or ship highly contaminated samples (concentrated wastes, free product, etc.) or samples suspected of containing high contaminant concentrations in the same cooler or shipping container with other environmental samples. 4.4 Chain of Custody Chain-of-Custody control will be maintained from sampling through analysis to prevent tampering with analytical specimens. Chain-of-Custody control procedures for samples will consist of the following: 1. Chain-of-Custody will originate at the laboratory with the shipment of prepared sample bottles and blank(s) in sealed coolers. Container kits will be shipped by express carrier to the sampler or site or picked up at the laboratory. DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 23 2. Following sample kit receipt, the sampler will inventory the container kit, and check its consistency with number and type of containers indicated in the Chain-of-Custody forms and required for the sampling event. 3. Labels for individual sample containers will be completed in the field, indicating the site name, sampling time and date, sample location/well number, analysis required, sampler’s initials, and preservation methods used for the sample. 4. Collected specimens will be placed in the iced coolers and will remain in the continuous possession of the field technician until shipment or transferal as provided by the Chain-of-Custody form has occurred. If continuous possession cannot be maintained by the field technician, the coolers will be temporarily sealed and placed in a secured area. 5. Following laboratory delivery, samples will be issued a laboratory sample number and recorded into a logbook indicating client, sample location/well number, and delivery date and time. The laboratory director or his designee will sign the Chain-of-Custody control forms and formally receive the samples. 6. Chain-of-Custody form copies will be placed in the laboratory's analytical project file and attached to the laboratory analysis report following analysis. Chain-of-Custody forms will be used to transfer direct deliveries from the sampler to the laboratory. A coded, express delivery shipping bill shall constitute the Chain-of Custody between the sampler and laboratory for overnight courier deliveries.

DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 25 6.0 LABORATORY ANALYSIS The ground and surface water parameters will be analyzed for field water quality indicators (pH, conductivity, temperature and turbidity) and those constituents listed in Table 2. Analytical methods will follow Test Methods for Evaluating Solid Waste - Physical/Chemical Methods (SW-846) or Methods for the Chemical Analysis of Water and Wastes and will be consistent with the DWM’s policies regarding analytical methods and reporting limits. Analysis will be performed by a laboratory certified by the North Carolina DWM for the analyzed parameters. 6.1 Laboratory Quality Assurance/Quality Control Formal environmental laboratory Quality Assurance/Quality Control (QA/QC) procedures are to be utilized at all times. The landfill owner/operator is responsible for selecting a laboratory contractor and insuring that the laboratory is utilizing proper QA/QC procedures. The laboratory must have a QA/QC program based on specific routine procedures outlined in a written laboratory Quality Assurance/Quality Control Manual. The QA/QC procedures listed in the manual shall provide the lab with the necessary assurances and documentation that accuracy and precision goals are achieved in analytical determinations. Internal quality control checks shall be undertaken regularly by the lab to assess the analytical procedures precision and accuracy. 6.2 Laboratory Quality Control Checks The internal quality control checks include calibration standards, standard references, duplicate samples, and spiked or fortified samples. Calibration standards shall be verified against a standard reference obtained from a second (alternate) source. For most analytical methods, calibration curves shall be developed using at least one (1) blank and three (3) standards. Samples shall be diluted, if necessary, to ensure that analytical measurements fall within the linear portion of the calibration curve. Where required, duplicate samples shall be processed at an average frequency of 10 percent to assess the precision of testing methods, and standard references shall be processed not less than monthly to assess the accuracy of analytical procedures. Method or procedural blanks and spiked or fortified samples shall be carried through sample preparation and measurement to validate the efficiency and accuracy of the analysis. 6.3 Data Review During analyses, quality control and sample data shall be reviewed by the laboratory manager to identify questionable data and determine if the necessary QA/QC requirements are being followed. If a portion of the lab work is subcontracted, it is the contracted laboratory’s responsibility to verify that subcontracted work is completed by certified laboratories, using approved QA/QC procedures. DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 26 7.0 RECORD KEEPING AND REPORTING This section addresses the documentation and reporting requirements associated with the WQMP implementation. 7.1 Groundwater System Evaluations After each monitoring event, the potentiometric surface will be evaluated to determine if the monitoring system is adequate to provide early detection of a release from the landfill unit and to determine the rate and direction of groundwater flow at the site. The groundwater flow direction will be confirmed by comparing the most recent groundwater surface elevations across the site using a potentiometric surface map. Groundwater flow rates will be calculated using the following equation: V=Ki/n Where: V = Velocity (feet/day) K = Hydraulic Conductivity (feet/day) i = Hydraulic Gradient (foot/foot) n = Effective Porosity of aquifer soils (unit less) If these evaluations indicate the groundwater monitoring system requires modification to meet rule requirements, a work plan and revised WMQP will be submitted to NCDWM for review prior to modifications to enhance the monitoring system. 7.2 Reporting A report summarizing the monitoring event and the analytical data from the event will be submitted to the DWM within 120 days following receipt of laboratory analytical data. Monitoring reports will include the following: 1. An discussion of site geology and hydrogeology; 2. A discussion of the monitoring event procedures and results; 3. An potentiometric surface map; 4. Analytical laboratory reports and summary tables; 5. Graphical analysis of analytical data may be reported but is not required; 6. Solid Waste Environmental Monitoring Reporting Form (Appendix B); and 7. Laboratory Data (in Electronic Data Deliverable Format – see Section 2.2.1). Monitoring reports may be submitted electronically by e-mail or in paper copy form. Report copies will be kept at the landfill office. DocuSign Envelope ID: 593AF09C-165A-4A52-836F-55BB87DDBC36 WI High Point C&D Landfill Water Quality Monitoring Plan November 2016 Page 27 8.0 MONITORING PROGRAM MODIFICATIONS This section addresses the procedures that should be followed with respect to any water quality program modifications. 8.1 Well Abandonment/Rehabilitation After each water quality monitoring event, the potentiometric surface will be evaluated to determine whether the monitoring system is still effective at detecting an early release from the landfill, and to determine the groundwater flow rate and direction at the site. If the potentiometric maps reveal the depths, locations, or well number is insufficient to monitor for a potential releases of solid waste constituents from the solid waste management area, new well locations and depths will be submitted to the DWM for approval. Should wells become irreversibly damaged or require rehabilitation, the DWM will be notified. If monitoring wells and/or piezometers are damaged irreversibly they will be abandoned under DWM direction following 15A NCAC 02C .0113. The abandonment procedure in unconsolidated materials involves over-drilling and/or pulling the well casing and plugging the well with a sealant such as neat cement grout and/or bentonite clay. For bedrock well completions the abandonment encompasses plugging the interior well riser and screen with a sealant such as neat cement grout and/or bentonite clay sealant. 8.2 Additional Well Installations Additional well installations will be carried out in accordance with DWM directives. Monitoring wells will be installed under the supervision of a North Carolina registered geologist or engineer who will certify to the DWM that the installation complies with the North Carolina 2C Regulations. For future well installation, the documentation for well construction will be submitted by the registered geologist or engineer to the DWM within thirty (30) days following well construction. 8.3 Implementation Schedule The Monitoring Program proposed herein will be implemented following approval of this Water Quality Monitoring Plan by the DWM.
