(CEC) has prepared this Spring 2017 Semi-Annual Water Quality Monitoring Report for the GWS Landfill (formerly Highway 55 C&D Landfill). This report describes the well gauging and field sampling activities, and provides a summary of the site groundwater conditions and acquired groundwater sample data. -2- Spring 2017 Water Quality Monitoring Report August 2017 2.0 SITE DESCRIPTION AND BACKGROUND Greenway Waste Solutions of Apex, LLC (GWS) operates the subject landfill facility under Solid Waste Facility Permit Number 92-30. The facility address is 5940 Old Smithfield Road, Apex, North Carolina. A Site Location Map is attached as Figure 1. The property is bounded by the Triangle Expressway (Interstate 540) to the north, the South Wake Landfill to the south, Highway 55 to the east, and private property to the west. A tributary creek forms the southern property boundary, and a receptor creek forms the western property boundary. The Phase 1 and 2 disposal areas total approximately 32.6 acres. A Site Map is attached as Figure 2. The North Carolina Department of Environment and Natural Resources (now Department of Environmental Quality) – Solid Waste Section (NCDEQ-SWS) issued the original solid waste facility permit for the landfill facility on August 20, 2002. The facility will be completed in three phases. The permitted capacity and acreages of each of the phases are listed in the table below. Area Gross Capacity (cy) Acreage Phase 1 858,000 17.8 Phase 2 1,100,000 14.8 Phase 3 900,000 11.2 Totals 2,858,000 43.8 CEC last updated the facility Groundwater Detection Monitoring Plan in May 2016. The updated plan includes the installation of new detection wells approved for the Phase 3 expansion area and the addition of two more surface water sampling locations. Whereas, C&D waste has not yet been disposed in the Phase 5 expansion area, CEC performed the recent monitoring activities to address the existing Phase 1 and 2 landfill areas. -3- Spring 2017 Water Quality Monitoring Report August 2017 3.0 DESCRIPTION OF FIELD SAMPLING ACTIVITIES Field activities associated with the routine Spring 2017 semi-annual water quality monitoring were conducted by CEC personnel on April 19 and 20, 2017. CEC conducted additional groundwater sampling on June 15, 2017 to obtain quality control data. Project oversight was provided by an NC-licensed geologist. Well water levels were gauged, static well water was purged, and groundwater samples were collected from 11 monitoring wells including wells MW-1, MW-2, MW-3, MW-4, MW-5, MW-6, MW-7, MW-8, MW-9, MW-10, and MW-11. The approximate locations of these monitoring points are shown on Figure 2. Also, four surface water samples (SW-1 through SW-4) were collected from the creek along the western property boundary (SW-1 and SW-2) and the tributary creek along the southern property boundary (SW-3 and SW-4). The approximate surface water sampling locations are depicted on Figure 2. 3.1 WELL WATER LEVEL GAUGING Prior to well purging/sampling, the water level in each monitoring well was gauged using an electronic water level meter. The depth-to-groundwater as measured from a reference point on each well top-of-casing was recorded to the nearest 0.01-inch on the well sampling field log (see Appendix A). The water level probe was decontaminated between well measurements. 3.2 WELL PURGING CEC field personnel employed a peristaltic pump to purge the shallow monitoring wells at a low- flow rate until targeted analytical parameters were found to stabilize. During each well purge, specific conductance, pH, dissolved oxygen, and oxidation-reduction potential were frequently measured with an YSI 556 Water Quality Meter in a flow-through cell to observe and document the chemical stability of the formation water entering the monitoring well. When parameter values indicated stable water chemistry, as defined by USEPA Groundwater Sampling Guidelines for Superfund and RCRA Project Managers (EPA 542-S-02-001, May 2002), the well purge was considered complete and groundwater samples were then collected. Well purge data was recorded on the well sampling field logs provided in Appendix A. -4- Spring 2017 Water Quality Monitoring Report August 2017 3.3 GROUNDWATER SAMPLE COLLECTION Following the above-described well purging procedures, CEC field personnel collected groundwater samples from each well employing a peristaltic pump and the same low-flow pumping protocols used during the well purge. Groundwater samples were collected in laboratory- supplied sample containers that were labeled and then packed on ice in insulated coolers. The samples were either hand-delivered by CEC personnel or shipped overnight by FedEx to the selected analytical laboratory under chain-of-custody protocol. -5- Spring 2017 Water Quality Monitoring Report August 2017 4.0 GROUNDWATER FLOW EVALUATION A depth-to-water level measurement was performed relative to the well top-of-casing in each groundwater monitoring well prior to well purging. A water level elevation was calculated by subtracting the depth-to-water from the respective surveyed top-of-casing elevation datum. Monitoring well gauging data are summarized in Table 1. 4.1 GROUNDWATER POTENTIOMETRIC MAP Calculated static groundwater levels were used to prepare the Spring 2017 groundwater potentiometric map presented in Figure 3. Shallow groundwater movement beneath the landfill is semi-radial to the northwest and west toward a tributary creek located to the northwest and the receptor creek forming the west property boundary, respectively; and to the southwest toward the tributary creek forming the southern property boundary. 4.2 HORIZONTAL HYDRAULIC GRADIENTS AND GROUNDWATER FLOW VELOCITIES The horizontal hydraulic gradient (i) used in the flow velocity calculation below was estimated between the upgradient well MW-1 and downgradient well MW-5, which are separated by a distance of approximately 2,700 feet. Based on the calculated groundwater elevations for the April 2017 event, the hydraulic head difference between MW-1 (346.10 ft) and MW-5 (278.23 ft) is 67.87 feet. The head difference (67.87 ft) divided by the well separation distance (2,700 ft) is 0.025, the horizontal hydraulic gradient, unitless. Slug tests to estimate the horizontal hydraulic conductivity (K) in the vicinity of monitoring well MW-6 were conducted by Elite Techniques, Inc. in August 2013. The mean K calculated from the slug test data is 4.54 x 10-5 cm/sec (= 0.13 ft/day). Based on the known typical absence of significant fracturing within the massive conglomerate beneath the landfill footprint, the mean K of 10-5 cm/sec would appear to be a higher rate than the norm. Typical values for unfractured rock from the scientific literature suggest K values of 10-2 ft/year. -6- Spring 2017 Water Quality Monitoring Report August 2017 An effective porosity (ηe) of 10 percent was estimated based on the fractured conglomerate comprising the surficial aquifer at the site. Groundwater flow velocity calculations are included in Table 2. A groundwater flow velocity was estimated based on the April 2017 groundwater monitoring data. The flow velocity estimate was calculated by using the following equation: V = K x i ηe Where: V = groundwater flow velocity (ft/sec) K = horizontal hydraulic conductivity (ft/sec) i = horizontal hydraulic gradient (dh/dl, unitless) dh = difference in hydraulic head between wells (ft) dl = distance between wells (ft) ηe = effective porosity (%) TABLE 1 - AVERAGE GROUNDWATER FLOW VELOCITY ESTIMATE K (ft/day) i (ft) MW-1A to MW-5 ηe V (ft/day) V (ft/year) 0.13 0.025 0.10 0.033 11.86 Table Notes: V = (K x i)/ ηe Where: V = groundwater flow velocity (ft/sec) K = horizontal hydraulic conductivity (ft/sec) i = horizontal hydraulic gradient (dh/dl, unitless) dh = difference in hydraulic head between wells (ft) dl = distance between wells (ft) ηe = effective porosity (%) The groundwater flow velocity calculated for the May 2017 sampling event is approximately 12 feet/year. Flow values in less fractured rock would be on the order of 0.01 to 1.0 ft/year. -7- Spring 2017 Water Quality Monitoring Report August 2017 5.0 WATER SAMPLE ANALYTICAL PARAMETERS CEC submitted the routine semi-annual groundwater and surface water samples to TestAmerica Laboratories, Inc. (TA) for analytical testing. All 11 monitoring well samples and four surface water samples were analyzed for the following parameters: Appendix I Volatile Organic Compounds (VOCs) [EPA 8260B] Appendix I Metals [EPA 200.8] Mercury [EPA 245.1] Monitoring well samples were also tested for leachate indicator parameters including the following list: Alkalinity [SM 2320B] Sulfate EPA 9056A Chloride [9056A] Total Dissolved Solids (TDS) [2540C] For quality control purposes, CEC also submitted a blind duplicate sample (collected from MW- 8) to TA for analysis of Appendix I VOCs plus THF. In addition, CEC collected a split sample from MW-8 that was submitted to Pace Analytical Services, Inc. (Pace) laboratory for analysis of Appendix I VOCs plus THF. Due to conflicting laboratory analytical results from the initial round of sample analyses, CEC personnel re-sampled MW-8 on June 15, 2017 and submitted this sample to TA for analysis of Appendix I VOCs. -8- Spring 2017 Water Quality Monitoring Report August 2017 6.0 GROUNDWATER SAMPLE ANALYTICAL DATA EVALUATION The laboratory analytical data reports are provided in Appendix B. Summaries of Appendix I VOCs, Appendix I metals, and inorganic analytes detected in the collected groundwater samples at concentrations above their respective laboratory-reported detection limits are provided in Table 3. Historical Site Data Data discussed in this section draw inferences to historical well sampling data acquired at the landfill since 2012. Enviro-Pro, PC conducted the field monitoring activities, sample collection, and reporting for the routine semi-annual groundwater monitoring events from at least 2009 to 2016. Shealy performed the sample analyses for the semi-annual monitoring events since at least 2012, except for the most recent Spring 2017 monitoring event for which the analyses were performed by TA. The monitoring reports are submitted to the NCDEQ-SWS – Compliance Unit. Organic Analytes Detected at Concentrations Exceeding the 2L Standards For the Spring 2017 monitoring event, TA detected vinyl chloride in MW-8 at a concentration of 4.2 µg/L, which exceeds the 2L Standard of 0.03 µg/L. TA also detected 2.5 µg/L vinyl chloride in the blind duplicate sample that CEC collected from MW-8. However, for the split sample from MW-8 that CEC submitted to Pace for VOC analysis, Pace did not detect vinyl chloride above the laboratory reporting limit of <1.0 µg/L. For MW-8, unexpected vinyl chloride detections were reported by TA compared to the Pace results. CEC asked TA to review the results, analysis methodology, instruments used, and interviewed the analysts in an effort to either validate or discount this first round of 2017 results. TA brought in their Senior Technical Services Group to review their process. In late May, TA informed CEC of the following results of their investigation: 1. Search indicated a possibility of conversion of a Freon refrigerant (Freon 151) to vinyl chloride in the gas chromatograph (GC); -9- Spring 2017 Water Quality Monitoring Report August 2017 2. Confirmation of this occurred after TA obtained and ran a Freon 151 standard through their Chicago GCs, resulting in only one of the GCs not converting the Freon 151 to vinyl chloride; 3. A TA company-wide program was implemented and identified most of their GCs converting the Freon 151 to vinyl chloride; and 4. TA started, and is continuing, a corrective-action program to identify and change the component(s) of the GCs converting the Freon. (It is reported that the likely cause is the Purge and Trap mechanism.) On June 15, 2017, CEC re-sampled MW-8 and submitted the sample to TA for VOCs analysis. TA did not detect vinyl chloride in the second sample above the laboratory reporting limit of <0.5 µg/L. The confirmatory sample was analyzed by TA using a GC instrument that they previous tested and cleared to provide artifact-free vinyl chloride data. Following the June 2017 confirmation-resampling event, CEC received a letter from Shealy regarding in-house testing of their GC instruments documenting the results of their independent testing, which confirmed TA’s findings. Shealy also provided a letter from the supplier of the silica gel component in the GC purge and trap mechanisms (OI Analytical) that indicated the silica gel component may be the “active” Freon 151 to vinyl chloride conversion location. The documentation from TA, Shealy, and OI Analytical can be found in Appendix C. The confirmed conversion of Freon 151 to vinyl chloride explains the false detection of vinyl chloride in sample MW-8 at the Highway 55 Landfill. Confirmation of these findings from the Spring 2017 sampling will continue to take place for the near future as part of the approved groundwater monitoring plan. CEC will continue to obtain and analyze split samples and blind duplicates from selected groundwater monitoring wells. TA and Pace are continuing to conduct reviews of their GCs to eliminate the issue(s) converting the Freon to vinyl chloride. The presented data and supporting correspondence from the analytical laboratories directly working on the project clearly show that the vinyl chloride analytical data prior to the Spring 2017 sampling event have to be considered invalid. Any remedial efforts to address vinyl chloride -10- Spring 2017 Water Quality Monitoring Report August 2017 impacts above the 2L Standards will be based on sample data from the Spring 2017 event and future sampling events. Metal Analytes Detected at Concentrations Exceeding the 2L Standards As highlighted in Table 2, the laboratory test results for the monitoring event show that cobalt and vanadium exceed the NC Interim Maximum Allowable Concentrations (IMACs) in the majority of the landfill monitoring well samples. Cobalt was detected above its IMAC of 1 µg/L in MW- 3, MW-4, MW-5, MW-6, MW-7, MW-8, MW-11, SW-3, and SW-4. Vanadium was detected above its IMAC of 0.3 µg/L in MW-1, MW-2, MW-6, MW-8, MW-9, and SW-3. The uniformity of these detected cobalt and vanadium concentrations in the respective well samples suggests that they are representative of naturally occurring levels. Barium was detected at a concentration of 1,200 µg/L in upgradient well MW-1 and was detected at 1,400 µg/L in MW-10. These barium levels exceed the 2L Standard of 700 µg/L. MW-1 is an upgradient monitoring well, which suggests that the detected barium concentration in this well is likely related to an unknown upgradient source. Lead was detected at 21 µg/L in MW-6, which is above its 2L Standard of 15 µg/L. Elevated lead has not been typically reported in any well samples; thus, this lead detection should be confirmed by additional data collection. Inorganic Leachate Indicator Parameters The detections of inorganic parameters are summarized in Table 3. Detected total dissolved solids (TDS) levels in wells MW-1, MW-2, MW-3, MW-4, MW-10, and MW-11 exceeded its 2L Standard of 500 mg/L. Detected chloride concentrations in wells MW-1, MW-3, MW-9, and MW- 10 exceeded its 2L Standard of 250 mg/L. The detected sulfate concentration of 260 mg/L in MW- 11 was above the NC 2L Standard of 250 mg/L. The detected mercury concentration of 1.2 mg/L in upgradient well MW-1 exceeded its 2L Standard of 1 mg/L. -11- Spring 2017 Water Quality Monitoring Report August 2017 It is important to note that elevated chloride and TDS levels were observed in the upgradient on- site monitoring well MW-1, as well as downgradient on-site wells. Chloride and TDS levels were highest in MW-1 and MW-10. -12- Spring 2017 Water Quality Monitoring Report August 2017 7.0 SURFACE WATER SAMPLING DATA CEC personnel collected a total of four surface water samples (SW-1 through SW-4), which were taken from the creek along the western property boundary (SW-1 and SW-2) and the tributary creek along the southern property boundary (SW-3 and SW-4). The approximate surface water sampling locations are depicted on Figure 2. Surface water samples were analyzed for the constituents listed in Appendix I of 40 CFR Part 258. The stream sample analytical results are summarized in Tables 2 and 3. No Appendix I VOCs were detected above the laboratory reporting limits in the surface water samples. Several Appendix I metals including arsenic, barium, cobalt, copper, iron, lead, manganese, vanadium, and zinc were detected in at least one surface water sample. With the exception of copper, detected metals concentrations in the upstream background sample (SW-1 and SW-3) were higher than the downstream (SW-2 and SW-4) metals concentrations indicating that the metals and their concentrations detected in the surface water samples are naturally occurring. The maximum detected copper level of 16 µg/L in sample SW-4 is well below the NC surface water protection standards. -13- Spring 2017 Water Quality Monitoring Report August 2017 8.0 DEMONSTRATION LETTERS ON VINYL CHLORIDE AND METALS Per 15A NCAC 13B .0544 (b) (1) (I), on behalf of Greenway Waste Solutions of Apex, LLC (GWS), CEC prepared and submitted letters under separate cover to the NCDEQ-SWS – Compliance Unit presenting historical data and recent technical findings regarding the laboratory detections of vinyl chloride and on the presence of background metals in the groundwater underlying the landfill. Copies of these letters and supporting documentation are included in Appendix C. Both letters present and discuss data on laboratory error in falsely reporting vinyl chloride due to the Freon conversion and on the presence of naturally occurring metals in geology and hydrogeology at the landfill. -14- Spring 2017 Water Quality Monitoring Report August 2017 9.0 OTHER GROUNDWATER MONITORING ACTIVITIES On behalf of GWS, CEC submitted a request dated May 2, 2107 to the NCDEQ-SWS for the abandonment and subsequent re-location of detection monitoring well MW-11 in order to expand on-site road access to the compost storage area and general facility improvements to the landfill. The NCDEQ-SWS approved this request via email dated May 9, 2017 (see Appendix D). MW- 11 was abandoned-in-place on May 16, 2017 by an NC-certified well driller, Troxler Geologic Services, Inc. A Well Abandonment Record is included in Appendix D. According to the NCDEQ-SWS-approved well re-location plan, a replacement well MW-11R will be installed at the proposed location prior to the Fall 2017 groundwater monitoring event. The new well will replace the abandoned well in the detection groundwater monitoring network. In addition, CEC will update the current Groundwater Detection Monitoring Plan (May 2016) to reflect changes due to the new well locations and any monitoring tables, etc. -15- Spring 2017 Water Quality Monitoring Report August 2017 10.0 CONCLUSIONS AND RECOMMENDATIONS 10.1 CONCLUSIONS Routine field activities associated with the Spring 2017 semi-annual water quality monitoring event were conducted by CEC personnel on April 19 and 20, 2017. Well water levels were gauged, static well water was purged, and groundwater samples were collected from 11 monitoring wells. Surface water samples were collected from four creek locations. Due to a laboratory issue involving the conversion of Freon 151 to VC, CEC re-sampled MW-8 on June 15, 2017 and submitted the confirmatory sample to TestAmerica for VOC analysis. Vinyl chloride was not detected in the MW-8 re-sample at a concentration above the laboratory reporting limit of <0.5 µg/L. Analytical testing detected several leachate indicator parameters including chloride, sulfate, and TDS at concentrations above the 2L Standards. Chloride and TDS were detected at the most elevated levels in upgradient well MW-1. An upgradient source for elevated chloride and TDS has not been identified and is being further investigated. 10.2 RECOMMENDATIONS It is CEC’s technical opinion based on the quality assurance sampling and analytical data obtained during the Spring 2017 monitoring event that recent historical vinyl chloride detections in MW-8 are the result of laboratory artifacts. Laboratory instrumentation reviews have determined that when present Freon 151 will degrade to vinyl chlorine in GC instruments operating with certain purge and trap columns with a silica gel component. The well re-sample analysis in June 2017 is the only reported vinyl chloride data that should be representative of site groundwater quality. Confirmation of these second-round results from the Spring 2017 sampling will continue to take place for the near future as part of the approved groundwater monitoring plan. CEC will continue to obtain and analyze split samples and blind duplicates from selected groundwater monitoring -16- Spring 2017 Water Quality Monitoring Report August 2017 wells. TestAmerica and Pace are continuing to conduct reviews of their GCs to eliminate the issue(s) converting the Freon to vinyl chloride. Potential upgradient sources for elevated chloride and TDS detected in upgradient well MW-1 will be further investigated to evaluate the impact to the site groundwater. To minimize sampling artifacts and validate certain metals, chloride and TDS data, CEC will carefully monitor turbidity in the site monitoring wells during the well purge process. CEC will collect samples after achieving turbidity levels of 20 Nephelometric Turbidity Units (NTUs) or less, if practical. As a replacement for the recently abandoned MW-11, new detection monitoring well MW-11R will be installed at a NCDEQ-SWS-approved location prior to the Fall 2017 groundwater monitoring event. The new well will replace the abandoned well in the detection groundwater monitoring network. In addition, CEC will update the current Groundwater Detection Monitoring Plan (May 2016) to reflect changes due to the new well locations and any monitoring tables, etc. FIGURES REFERENCE DATE:DWG SCALE: DRAWN BY:CHECKED BY:APPROVED BY: PROJECT NO: FIGURE NO.: SITE LOCATION MAP 111-370.0031"=1000'AUGUST 2017 PNP EHS EHS 1 HIGHWAY 55 C&D LANDFILL GREENWAY WASTE SOLUTIONS OF APEX, LLC www.cecinc.com 1900 Center Park Drive - Suite A - Charlotte, NC 28217 Ph: 980.237.0373 · Fax: 980.237.0372 NORTH DATE:DWG SCALE: DRAWN BY:CHECKED BY:APPROVED BY: PROJECT NO: FIGURE NO.: SITE MAP 111-370.0031"=250'AUGUST 2017 PNP EHS EHS 2 HIGHWAY 55 C&D LANDFILL GREENWAY WASTE SOLUTIONS OF APEX, LLC REFERENCE www.cecinc.com 1900 Center Park Drive - Suite A - Charlotte, NC 28217 Ph: 980.237.0373 · Fax: 980.237.0372 NORTH LEGEND DATE:DWG SCALE: DRAWN BY:CHECKED BY:APPROVED BY: PROJECT NO: FIGURE NO.: POTENTIOMETRIC CONTOUR MAP 111-370.0031"=250'AUGUST 2017 JKS EHS EHS 3 HIGHWAY 55 C&D LANDFILL GREENWAY WASTE SOLUTIONS OF APEX, LLC www.cecinc.com 1900 Center Park Drive - Suite A - Charlotte, NC 28217 Ph: 980.237.0373 · Fax: 980.237.0372 NORTH REFERENCE LEGEND TABLES Table 1 Summary of Monitoring Well Gauging Data Highway 55 C&D Landfill Apex, North Carolina CEC Project No. 111-370.003 August 2017 MW ID Well Depth GRD Elev.Depth to TOS Depth to BOS TOS Elev.BOS Elev.TOC Elev.Depth to Water (TOC)WL Elev.

Receipt The samples were received on 6/17/2017 10:20 AM; the samples arrived in good condition, properly preserved and, where required, on ice. The temperature of the cooler at receipt was 2.0º C. GC/MS VOA Method(s) 8260B: The samples with positive detects for Vinyl Chloride in the presence of freon 151 were re-collected and the lab re-analyzed these on Instrument 25. The lab had determined this instrument to be "inert" to the degradation of freon 151 to Vinyl chloride. The results for Vinyl Chloride were significantly lower from the original samples. The lab analyzed the Freon 151 standard on this instrument before and after these samples were analyzed to confirm vinyl chloride was not detected and the instrument continues to be "inert". The following sample was re-collected and analyzed: MW-8 (500-129772-1). No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

(CEC), on behalf of Greenway Waste Solutions of Apex, LLC, is submitting this Demonstration Letter to establish that a natural variation in groundwater quality has caused contamination at the aforementioned facility. Certain metals have been detected in the groundwater that is sampled and analyzed per the approved Groundwater Monitoring Plan. These metals are regularly detected at concentrations exceeding their respective cleanup standards as published in 15A NCAC 02L .0202 (Standards), or published Interim Maximum Contaminant Levels (IMCL). This letter presents: • Statistical analysis used to determine metals of concern; • Condensed historical information on the detection of metals in groundwater at the landfill; • Information on the presence of reducing groundwater conditions and its impact on metal solubility and mobility; and • Summary of published information on the background presence of selected metals in groundwater and stream sediments. Attachments include a site plan depicting groundwater monitoring well locations, selected field data sheets on the latest sampling event; and figures on published stream sediment concentration data for selected metals. Ms. Jackie Drummond - NCDEQ CEC Project 111-370.0003 Page 2 August 2, 2017 Statistical Analyses and Metals of Concern Semi-annual groundwater monitoring has been performed at the landfill for an extended period. CEC tabulated and statistically analyzed historical groundwater data for the Facility for the period 2013 thru 2017 to determine metals of concern. The criteria for selection of metals of concern are: • Any constituent must have a minimum of two detections within 2013 and 2017 above method detection limit (MDL); • The geometric mean (GM) of the data for each constituent is then determined using only values greater than MDL; • A comparison is made between the GM against the Standard or IMCL (Standard/IMCL); and • If the comparison indicates the GM is greater than the Standard/IMCL, then the constituent is a metal of concern. Using the monitored wells, the analyses yielded three metals of concern: 1) Cobalt (1 µg/L) – GM of 5.6 µg/L, 9 samples above MDL; 2) Iron (300 µg/L) – GM of 1,669 µg/L, 17 samples above the MDL; and 3) Manganese (50 µg/L) – GM of 1,480 µg/L, 88 samples above the MDL. Condensed Historical Information The groundwater-monitoring program at the Highway 55 C&D Landfill currently consists of 11 groundwater monitoring wells. Semi-annual sampling and analysis is conducted per the approved Groundwater Monitoring Plan. For the time period evaluated, Appendix I metals have been analyzed. The first available data (2013) show that manganese was the first and most prevalent metal detected. Arsenic, barium, chromium, copper, lead, nickel and zinc were observed in the historical records at levels less than their applicable current Standard. Various semi-annual reports submitted by others state that the detected values represent background concentrations in the Piedmont. Groundwater Conditions and Its Impact on Bedrock Metal Mobility Two of the metals of concern, iron and manganese, are well recognized as being part of the Triassic Basin conglomerate. Both of these metals are easily mobilized from the conglomerate when reducing groundwater conditions are present. Field sampling logs generated by CEC personnel during the last two low-flow groundwater-sampling events identified a majority of the groundwater wells as having a negative Oxidation-Reduction Potential (ORP) measurement. This negative ORP indicates a reducing environment. A reducing environment allows for the converting insoluble forms of iron and manganese in the conglomerate to soluble salts resulting in elevated concentrations of these metals in the groundwater. CEC has also reviewed the historical field notes from 2013 to 2016. There are notations of high turbidity in some collected samples. Similar to the solubilizing of the iron and manganese in reducing conditions, high-turbidity in the Triassic groundwater is well understood to increase the total metal concentrations compared to a low-turbidity sample. The revised groundwater Ms. Jackie Drummond - NCDEQ CEC Project 111-370.0003 Page 3 August 2, 2017 sampling process of low-sampling now in practice should reduce the likelihood of high turbidity samples going forwards. Published Information on Selected Metals in Background Cobalt is also well understood to be present in the Triassic geology. The Energy, Land and Natural Resources Division of NCDEQ published maps(1) on the measured concentrations of this metal in stream sediments. This map can be found in the Attachments. In the map, significant concentrations of cobalt is observed in sediments. Cobalt in stream sediments has been observed to have concentrations ranging from 5 to 10 milligrams per liter in the general area of the Facility. Comparing the detected stream sediment concentrations to the GM concentration of 5.6 µg/L, the presence of cobalt due to naturally occurring background geology is concluded. Conclusion The presented data clearly supports the position that each of the six metals of concern detected in the Facility groundwater are due to their presence in the natural geology. These metals should then be removed from the Contaminants of Concern for the Facility at this time. If you have any questions or comments, please feel free to contact me at (980) 260-2130.

(CEC), on behalf of Greenway Waste Solutions of Apex, LLC has prepared and is submitting this Demonstration Letter presenting history and recently discovered facts regarding the detections of vinyl chloride in groundwater that is sampled and analyzed per the conditions in the above permit. Vinyl chloride is groundwater contaminant 145 as listed in 15A NCAC 02L .0202 and has a cleanup standard of 0.03 micrograms per liter (Standard) or the practical quantitation limit whichever is greater. This letter presents condensed historical information on the detection of vinyl chloride in groundwater at the landfill and then provides a timeline and facts generated during the investigation of higher than expected detection of vinyl chloride. Attachments include site plan showing well locations and correspondence from analytical laboratories certified by the state to perform groundwater organic analyses. Condensed Historical Information The groundwater-monitoring program at the Highway 55 C&D Landfill consists of a network of 11 groundwater monitoring wells and has been ongoing since operations at the Landfill started. Available information on groundwater sampling results starts in the fall of 2009. Semi-annual sampling takes place and the samples analyzed per the approved groundwater-monitoring plan. CEC has reviewed the available groundwater sampling result data from 2013 until spring of 2017. Two monitoring wells (MW-2/MW-8) at the Facility contained vinyl chloride at concentrations above the practical quantitation limit during the fall 2016 sampling. In 2013, the first detection of vinyl chloride occurred in MW-8. At a permitted facility operated by Greenway Waste Solutions of North Meck a similar vinyl chloride data history exists. As part of CEC’s review of the North Meck vinyl Ms. Jackie Drummond - NCDEQ CEC Project 111-370.0003 Page 2 August 2, 2017 chloride history and after detailed review of the historical data for the Highway 55 C&D Landfill, CEC was tasked with sampling the groundwater monitoring wells in 2017. For the spring 2017 groundwater-sampling event, CEC obtained split samples and these were delivered to TestAmerica and Pace Analytical Laboratories. For certain samples, higher than expected values of vinyl chloride were reported by TestAmerica compared against the Pace results. CEC asked TestAmerica to review the results, analysis methodology, instruments used and interview the analysts in an effort to either validate or discount this first round of 2017 results. TestAmerica brought in their Senior Technical Services Group to review their process. In late May, TestAmerica informed CEC of the following results of their investigation: 1. Search indicated a possibility of conversion of a Freon refrigerant (Freon 151) to vinyl chloride in the GC; 2. Confirmation of this occurred after TestAmerica obtained and ran a Freon 151 standard through their Chicago GCs, resulting only one of the GCs not converting the Freon 151 to vinyl chloride; 3. A TestAmerica company-wide program was implemented and identified most of their GCs converting the Freon 151 to vinyl chloride; and 4. TestAmerica started, and is continuing, a corrective-action program to identify and change the component(s) of the GCs converting the Freon. (It is reported that the likely cause is the Purge and Trap mechanism.) After receiving the information that the analytical procedure and equipment were the cause of the higher than expected groundwater vinyl chloride results, CEC resampled MW-8 at the Highway 55 C&D Landfill in June 2017. The comparison of the recent historical vinyl chloride results are shown in the following table: Table 1 – Vinyl Chloride Results Fall 2016 to Spring 2017 Results are shown in µg/L BOLD = value exceeds the PQL or Standard of 0.03 µg/L for vinyl chloride A figure showing the facility’s wells can be found in Attachment B.

The various pieces of correspondence from TestAmerica, Shealy and OI Analytical can be found in Attachment C. Impacts on Compliance Status The confirmed conversion of Freon 151 to vinyl chloride explains the higher than expected historical data on vinyl chloride at the Highway 55 C&D Landfill. The groundwater as measured at the Facility does not exhibit a groundwater violation of the published standards for volatile and semi-volatile organic compounds. However, CEC and Greenway recognize that only one data point at this time is considered reliable for vinyl chloride. We are proposing to continue the sampling program specified in the approved groundwater-monitoring plan. Confirmation of these second round results from the spring 2017 sampling will continue to take place for the near future until the required four rounds of data show compliance with the Standards. CEC will continue to obtain an analyze split samples and blind duplicates from selected groundwater monitoring wells as we have recently done. TestAmerica and Pace are continuing to work through reviews of their GCs to eliminate the issue(s) converting the Freon to vinyl chloride. Conclusion CEC on behalf of our client is requesting that NCDEQ discount the vinyl chloride analytical data when reviewing historical information from prior to 2017.

All the samples that we are detecting vinyl chloride have the tentatively identified compound 1-chloro-1-fluoroethane (molecular weight 82.5 aka Freon 151) which is breaking down in the autosampler metal sample pathway to vinyl chloride (molecular weight 62.5). This is likely occurring in the 6 port valve of the autosampler where actives site are catalyzing HF which accounts for 20 AMUs. I discussed this with Test America staff since they had the large discrepancy between the two labs. It appears that some autosamplers are most likely to have the active sites that cause this degradation of Freon 151. They have witnessed this specific issue first hand at Test America as well. We have ordered a single standard of Freon 151 which we will run on several instruments to determine if any do not cause the degradation. This situation is fairly rare, but due to the presence of Freon 151 in these samples the conditions were right to form vinyl chloride. I will call you to discuss, but wanted to get you in the loop now so you can pass this on to your client and the applicable regulators. Once we analyze the Freon 151 standard we should be able to switch out some components in our autosamplers to remove the active site thus preventing the formation of vinyl chloride. If we demonstrate we can eliminate the degradation issue we certainly want to talk to you about systematically getting this groundwater work back. We have supported these sites for many years and appreciate the scope or requirements.

Page 1 of 3 TestAmerica Chicago Corrective Action Report Client: Civil and Environmental Consultants Inc. Project: NC Landfills Site: NC North Mecklenburg Landfill, NC Highway 49 Landifll, NC Apex Landfill, NC Responsible Parties: TestAmerica Chicago Date Initiated: 05/24/17 Initiator: JoAnn Petruszak-Kmetty Description of Problem: The client requested that the vinyl chloride (VC) data for job 500-127404 from the North Mecklenburg Landfill - Infill be re-reviewed because the results were “an order of magnitude greater than the split samples results”. During the review, it was observed that each sample that had a positive detect for vinyl chloride also had a tentatively identified compound (TIC) identified as 1-chloro-1-fluoroethane (Freon 151). An inquiry was made of the other TestAmerica laboratories and the technical support personnel within TestAmerica to see if others have seen this correlation. After a preliminary investigation was performed at three TestAmerica laboratories, the TestAmerica Technical Support Organization (TSO) determined that false positive or high-biased results for vinyl chloride can occur due to the degradation of 1-chloro-1-fluoroethane (Freon 151) on some VOA GC/MS instruments. Freon 151 is not a VOA target analyte and it is not commonly found in the environment, but it is present more frequently in landfill leachates and monitoring wells. All of the vinyl chloride artifacts attributable to Freon 151 that we have identified to date are associated with landfill operations. When samples containing Freon 151 are analyzed on certain VOA GC/MS instruments that ‘activate’ or promote its degradation, vinyl chloride artifacts will Page 2 of 3 TestAmerica Chicago be generated. Some VOA instruments are highly ‘activated’ towards Freon 151 degradation, while others are quite ‘inert’. Freon 151 degradation is believed to occur on active sites in the VOA instrument ‘sample pathway’ that have developed over time, and may be difficult to reverse. Freon 151 has a characteristic mass spectrum and is easy to identify by library search. It will usually be evident as a significant peak eluting shortly after vinyl chloride. Corrective Action Plan: To correct the immediate problem, the following actions were taken: 1) Analyze a Freon 151 standard at ~ 300 ppb concentration on all VOC instruments. 2) Identify VOC instruments as ‘activated’ if VC is > RL, and ‘inert’ if VC is < RL, in the analysis of the Freon 151 standard. 3) Monitor each presumptive positive detect for VC on an activated instrument for the presence of Freon 151. If Freon 151 is present, re-analyze samples with presumptive positives for VC on an inert instrument. 4) When/where possible, perform maintenance on activated instruments to eliminate active sites and ensure inert status. 5) Review previous jobs that were analyzed from these sites and identify samples that had Freon 151 and VC detects. Status as of 6-12-17: The TestAmerica Chicago laboratory has analyzed a Freon 151 standard on each VOA instrument in the laboratory and has identified which instruments are ‘activated’ and which instruments are ‘inert’. All analysts have been informed of the situation and instructed to re-analyze samples with positive detects for VC and Freon 151 on an instrument which has been determined to be ‘inert’. The laboratory project manager will be informed of the situation and the client will be notified if data is impacted. The project manager will flag each known project site that historically has had Freon 151 with a method comment in TALs computer system so that it will appear on the analyst’s backlog upon arrival of samples to the laboratory. The following jobs have been reviewed and samples containing VC and Freon 151 have been identified: 500-127325, -127370, -127404, -127480, -127268, and -126939. The results have been flagged with a ‘cn’ flag and narrated. Page 3 of 3 TestAmerica Chicago The TestAmerica Chicago laboratory is in the process of performing maintenance on the activated instruments to minimize or eliminate the active sites to ensure an inert status. Further Corrective Action Needed: 1. Systematically clean or replace sample pathway to identify location of active site within the instrumentation. 2. 3.

The stated reason for the request is to accommodate construction of a new access road and for general facility routing improvements. We agree that relocating these two monitoring wells as proposed will maintain the integrity of the groundwater monitoring and methane monitoring at the facility. According to information provided by CEC, MW-11 was last sampled in April 2017 and MM-9 was last monitored on May 4, 2017. The next scheduled monitoring events at the GWS’s Apex C&D Landfill facility are: semi-annual groundwater monitoring in October 2017, and quarterly methane monitoring in August 2017. According to the proposed plan, GWS will abandon (in place) wells MW- 11 and MM-9 and install new wells at the proposed locations prior to the next monitoring events. The new wells will replace the abandoned wells in their respective monitoring networks. The Section requests the following for abandoning the wells: · MW-11 and MM-9 shall be properly abandoned and sealed in accordance with 15A BCAC 2C .0113, entitled “Abandonment of Wells”, and · Well abandonment records (GW-30 form) for each decommissioned piezometer, boring, and groundwater monitoring well must be certified by a Licensed Geologist in accordance with rule .1623(b)(2)(1) and submitted to the Solid Waste Section in accordance with 15A NCAC 2C. 0114(b). · Update the Water Quality Monitoring and Landfill Gas Monitoring Plans (May 2016) to reflect changes due to the new well locations and any monitoring tables etc. In addition, please contact me on the schedule for abandonment and installation so that I may option whether to visit the site during well drilling. If, for some reason, the wells are not abandoned prior the next scheduled monitoring events, continue collecting and reporting monitoring data from these wells until further notice. If you have any questions, feel free to call or email. Thank you.

The attached site map depicts the proposed new well location area to the north of their existing well placements. Please note that MW-3 shown on the map was the location of a former piezometer that has been abandoned. The new proposed groundwater monitoring well location is optimal for detecting the locally converging groundwater flow in this north-central area of the landfill facility. On behalf of GWS, CEC will conduct the current required monitoring before abandoning the existing wells. With your approval, GWS would like to abandon these existing wells ASAP to expedite the facility improvements. The well replacements will be completed prior to the next quarterly monitoring event. Please advise.
