Per the North Carolina Department of Environmental Quality approval letter dated October 8, 2015, the routine groundwater and surface monitoring frequency for Piedmont Landfill is reduced from semiannual to annual. The report package includes an Environmental Monitoring Reporting Form and the complete WQMR and laboratory data in electronic format. Samples were collected by Professional Technical Support Services (ProTech) on March 14-15, 2017, and leachate samples by Joyce Engineering on May 3, 2017. All samples were transported to the Test America, Inc. laboratory in Arvada, Colorado for analysis. The Piedmont Landfill and Recycling Center is a closed municipal solid waste facility that last received waste in 2004 and entered into post closure care in accordance with Rule .1627(d) of the North Carolina Solid Waste Management Regulations (NCSWMR) as of October 29, 2004. All points at the facility are currently being monitored under a Detection Monitoring Program under Rule .1633 of the NCSWMR. An exceedance of the NC2L groundwater standard for chromium was detected in well MW-03; however, an Alternate Source Demonstration for chromium was submitted on July 26, 2010, and was approved by the Solid Waste Section (SWS) in a letter dated April 28, 2011. There were no other exceedances of Groundwater Protection Standards for any NCSWMR Appendix I constituents during the 2017 annual sampling event. A copy of this report will be placed into the site’s operating record in accordance with Rule .1633(c)(1) of the NCSWMR. The next sampling event for the Piedmont Landfill and Recycling Center is scheduled for the first quarter of 2018 in accordance with the Water Quality Monitoring Plan, Revised December 2015, and approved by the SWS in a letter dated January 12, 2016.

This report may also serve to fulfill the notification requirements of Rule .1635 (g) of the North Carolina Solid Waste Management Regulations (NCSWMR). An Environmental Monitoring Reporting Form (EMRF) for this event is attached. Sampling for the event was performed on March 14-15, 2017, by ProTech. During this annual event, the site compliance wells and surface water monitoring points were sampled and analyzed for the NC Appendix I list of constituents. The site leachate was also sampled on May 3, 2017, to be included with this event for the required list of parameters. The laboratory analytical reports, field data logs, and chains of custody are provided as Appendix A of this report. MONITORING NETWORK: The current monitoring network for this facility was accepted by the North Carolina Department of Environmental Quality (NCDEQ) in a letter dated January 12, 2016, in response to the facility’s revised Water Quality Monitoring Plan dated December 2015. The current network consists of 11 monitoring wells: MW-01, MW-02, MW-03, MW-04, MW-05, MW-07, MW-08, MW-9R, MW-10, MW-11, and MW-12. MW-01 is an upgradient background well and the others are downgradient compliance wells. The locations of the monitoring wells are shown on Drawing 1 (presented in Appendix B). Table 1 presents the construction data for the monitoring wells. The monitoring wells are sampled annually in accordance with the North Carolina Solid Waste Management Regulations (NCSWMR) and the Water Quality Monitoring Plan for this facility. Mr. Al Lacsamana June 20, 2017 Page 2 of 5 Surface water at the facility is monitored annually in conjunction with the groundwater sampling events. Samples are collected from four surface water monitoring points: S-02, S-03, S-04, and S-05. Surface point S-01 was removed from the monitoring program as approved in a letter from the North Carolina Department of Natural Resources (DENR), now the NCDEQ, dated July 15, 2010. The locations of the surface water points are shown on Drawing 1. MONITORING PROGRAM HISTORY: The site entered into an Assessment Monitoring Program for background wells MW-01 and MW-06 and downgradient well MW-09 after volatile organic constituents were detected in MW-09 during the second semiannual event of 1996. Two organic compounds (chloroethane and 1,1-dichloroethane) were historically detected in monitoring well MW-09. Chloroethane exhibited a declining trend to the point where chloroethane was reported at less than the laboratory reporting limit during the January 1998 sampling event. The concentration of 1,1-dichloroethane in MW-09 also decreased below the laboratory reporting limit during the July 1998 sampling event. Following receipt of approval from DENR, all wells at the site reverted to the Detection Monitoring Program as of the second semiannual event in 1999, as allowed by 15A NCAC 13B.1634 (b). Monitoring well MW-09 was replaced by well MW-09R in November 1999. No chloroethane concentration above the laboratory reporting limit or Solid Waste Section Limit (SWSL) has been detected in MW-09R since the well was installed; however, 1,1-dichloroethane was detected in MW-09R at a concentration of 23 g/L during the initial sampling event conducted in January 2000. The concentration of 1,1-dichlorothane remained relatively consistent until 2009, ranging in concentration from 7 g/L to 28 g/L; however, it has not been detected at quantifiable levels since September 2009. The constituent cis-1,2-dichloroethene was detected in MW-09R above the laboratory reporting limit for the first time during the July 2002 event at a concentration of 6.5 g/L, and has been detected at concentrations ranging from 5-28 µg/L; however, it has not been detected at quantifiable levels since September 2009. The presence of organic constituents in MW-09 and MW-09R is attributed to landfill gas (LFG). The LFG extraction network was expanded in this area in January 2003, and the recent decrease in concentrations of organic constituents in this well is attributed to the control of LFG. Due to the detection of 1,1-dichloroethane in MW-09R during the first semiannual event in 2000, the site performed Assessment Monitoring on wells MW-01, MW-06, and MW-09R through the second semiannual event of 2001. Following DENR approval of an August 20, 2001 request by Waste Management, MW-01 and MW-06 again reverted to Detection Monitoring. Monitoring well MW-09R was sampled for the NC Appendix I list of constituents plus detected Appendix II constituents during the first semiannual event each year and NC Appendix II list of constituents during the second semiannual event until the DENR approved reverting back to detection monitoring in a letter dated March 15, 2012. Mr. Al Lacsamana June 20, 2017 Page 3 of 5 In the September 2007 sampling event, benzene and vinyl chloride were detected in MW-02 at concentrations in exceedance of the groundwater standards established in 15A NCAC 2L.020 (NC2L). A resampling event confirmed the vinyl chloride, but not the benzene exceedance. An Alternate Source Demonstration (ASD) was submitted to DENR on March 14, 2008. The ASD demonstrated that the organic constituents detected in MW-02 are related to LFG impacts. In January 2008, improvements to the active LFG recovery system at the site were initiated to help mitigate these impacts. The ASD was accepted by DENR in a letter dated May 7, 2008 with the condition that if vinyl chloride and benzene concentrations in MW-02 are not sufficiently reduced by spring 2009, MW-02 would enter Assessment Monitoring. Neither benzene nor vinyl chloride have had confirmed detections above the NC2L standards in MW-02 since September 2008, so MW-02 remains in detection monitoring. During the March 2010 sampling event, chromium was detected in MW-03 at a statistically significant concentration above the NC2L groundwater standard. An ASD was submitted on July 26, 2010 for the chromium demonstrating that the chromium was naturally occurring in the soil and groundwater of the facility. DENR approved the ASD for chromium at the facility in a letter dated April 28, 2011. A Request to Reduce Monitoring Requirements was submitted to the NCDEQ by Joyce Engineering in a report dated September 23, 2015, on behalf of Waste Management. The report requested that the frequency of water quality sampling be reduced from semiannual to annual, and it requested the removal of wells MW-4D, MW-6, MW-11D, and MW-12D from the compliance network. NCDEQ approved the request in a letter dated October 8, 2015. A revised Water Quality Monitoring Plan for the Piedmont Landfill & Recycling Center, Permit 34-06, was then submitted to the NCDEQ in December 2015, reflecting the approved changes. The revised Water Quality Monitoring Plan, was approved for the facility by the NCDEQ in a letter dated January 12, 2016. DETECTION MONITORING EVENT: MW-01, MW-02, MW-03, MW-04, MW-05, MW-07, MW-08, MW-9R, MW-10, MW-11, MW-12, and Surface Water Points: S-02, S-03, S-04, and S-05 The 2017 annual sampling event was conducted by ProTech on March 14-15, 2017. Eleven monitoring wells and four surface water points were sampled for the NC Appendix I list of constituents. The laboratory analytical reports, field data logs, and chains of custody for the 2017 annual event are provided in Appendix A of this report. Table 2 presents the quantified detections above the NCDEQ Solid Waste Section Reporting limits (SWSL) for the 2017 sampling event. Table 3 presents the exceedances of 15A NCAC 2L.0202 Groundwater Standards (NC2L Standards) or the NCDEQ Solid Waste Section Groundwater Protection Standards (GWPS) for the 2017 sampling event. Table 4 presents the field parameters for the March 2017 sampling event. Mr. Al Lacsamana June 20, 2017 Page 4 of 5 Organic Constituents There were no quantified detections (above the SWSL) of any Appendix I organic constituents in any of the monitoring wells or surface water points during the 2017 Annual sampling event. Inorganic Constituents Two inorganic constituents had quantified detections (above the SWSL) in one or more monitoring wells. These included barium in MW-02 and chromium in MW-03. Zinc in MW-08 was blank-qualified by a detection in the field blank. Chromium was detected above the NC2L Standard in MW-03. An ASD for chromium was approved by the NCDEQ in a letter dated April 28, 2011; therefore, the detections are not considered regulatory exceedances of Groundwater Protection Standards (GPS). No other Appendix I inorganic constituents were detected above the SWSL or the NC2L or GWPS in any monitoring well. There were no quantified detections (above the SWSL) of any inorganic constituents in any of the surface water samples collected during the 2017 annual sampling event. SUBMITTAL OF LEACHATE ANALYTICAL DATA: Appendix A to this report contains the leachate monitoring results for the May 3, 2017, sampling event as requested in the Solid Waste Section memo dated November 13, 1996, and confirmed by DEQ as required in May 2017. The leachate was analyzed for NC Appendix I constituents, alkalinity, carbonate alkalinity, bicarbonate alkalinity, TDS, TOC, chloride, ammonia, sulfate, nitrate, phosphorus, BOD, COD, TSS, mercury, indicator metals (calcium, iron, magnesium, manganese, sodium, and potassium), and the required field parameters. SUBMITTAL OF GROUNDWATER MAP AND FLOW CALCULATIONS: Appendix B to this report contains the groundwater surface potentiometric surface map (Drawing 1) and groundwater flow rates for this event. In summary, the 2017 sampling results and groundwater flow assessment indicate that the site monitoring network is effective in monitoring for the release of solid waste constituents to the environment. CONCLUSIONS/CLOSURE: There were no organic constituents with quantified detections (above the SWSL) reported for any monitoring wells or surface water points during the 2017 annual monitoring event. Two inorganic constituents had quantified detections in two monitoring wells, and chromium was detected above the NC2L groundwater standard in MW-03. An ASD was submitted on July 26, 2010, for the exceedance of chromium during the March 2010 sampling event. On April 28, 2011, DENR, now NCDEQ, approved the ASD for chromium at the facility. MW-03 will continue to be monitored in accordance with the Detection Monitoring Program. Mr. Al Lacsamana June 20, 2017 Page 5 of 5 The current approved monitoring network will continue to be monitored in accordance with the Detection Monitoring Program and surface water points will continue to be monitored as required by the NCDEQ. The frequency of groundwater and surface water monitoring for the closed Piedmont Landfill and Recycling Center has changed to annual as approved by NCDEQ in correspondence dated October 8, 2015. Therefore the next groundwater and surface water monitoring event is scheduled for the first quarter of 2018. If you have any questions, feel free to contact me at (336) 323-0092.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. The reporting limits (RLs) in this report are North Carolina SWSLs. Sample Receiving The samples were received on 03/16/2017; the samples arrived in good condition, properly preserved and on ice. The temperature of the cooler at receipt was 0.3 C. Holding Times The holding times were within established control limits. Method Blanks All Method Blanks were within established control limits. Laboratory Control Samples (LCS) All Laboratory Control Samples were within established control limits. Matrix Spike and Matrix Spike Duplicate (MS/MSD) All MS/MSD samples were within established control limits. Metals The Instrument Blank was above the upper control limit for Total Copper during Method 6020A analysis. Because the data are considered to be biased high and Total Copper was not detected in the samples above the reporting limit, corrective action was deemed unnecessary. 03/30/2017Page 3 of 102 EXECUTIVE SUMMARY -

Pursuant to NELAP, this report shall not be reproduced except in full, without the written approval of the laboratory. All questions regarding this report should be directed to the TestAmerica Denver Project Manager. The Lab Certification ID# is 4025. Reporting limits are adjusted for sample size used, dilutions and moisture content if applicable. TestAmerica Laboratories, Inc. TestAmerica Denver 4955 Yarrow Street, Arvada, CO 80002 Tel (303) 736-0100 Fax (303) 431-7171 www.testamericainc.com Page 1 of 50 CASE NARRATIVE Client: Waste Management Project: 134|Piedmont Landfill Report Number: 280-94901-1 With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. This report may include reporting limits (RLs) less than TestAmerica’s standard reporting limit. The reported sample results and associated reporting limits are being used specifically to meet the needs of this project. Note that data are not normally reported to these levels without qualification because they are inherently less reliable and potentially less defensible than required by the latest industry standards. Sample Receiving The samples were received on 03/16/2017; the samples arrived in good condition, properly preserved and on ice. The temperature of the cooler at receipt was 3.1C. Holding Times The holding times were within established control limits. Method Blanks All Method Blanks were within established control limits. Laboratory Control Samples (LCS) All Laboratory Control Samples were within established control limits. Matrix Spike and Matrix Spike Duplicate (MS/MSD) The Method 8260B MS/MSD performed on the sample 3406-S02 exhibited a RPD result outside the RPD limit for Acetone. A short compound list was reported for the Method 8260B MS/MSD and therefore Acetone is not reported in the MS/MSD section. Because the corresponding Matrix Spike and Matrix Spike Duplicate recoveries, Laboratory Control Sample, and Method Blank sample were within control limits, this anomaly is considered to be due to matrix interference and no corrective action was taken. All other MS/MSD samples were within established control limits. Metals Copper is present in the continuing calibration blank associated with QC batch 280-366863. This is an indicator that data may be biased high. As no detectable concentrations of Copper are present in the associated samples, corrective action is deemed unnecessary.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. This report may include reporting limits (RLs) less than TestAmerica’s standard reporting limit. The reported sample results and associated reporting limits are being used specifically to meet the needs of this project. Note that data are not normally reported to these levels without qualification because they are inherently less reliable and potentially less defensible than required by the latest industry standards. Sample Receiving The samples were received on 05/04/2017; the samples arrived in good condition, properly preserved and on ice. The temperature of the cooler at receipt was 0.1 C. Holding Times The holding times were within established control limits. Method Blanks Total Barium, Total Sodium Method 6010C, Total Alkalinity and Bicarbonate Alkalinity Method 2320B were detected in the Method Blanks below the project established reporting limit. No corrective action is taken for any values in Method Blanks that are below the requested reporting limits. All other Method Blanks were within established control limits. Laboratory Control Samples (LCS) All Laboratory Control Samples were within established control limits. Matrix Spike and Matrix Spike Duplicate (MS/MSD) The Matrix Spikes and Matrix Spike Duplicates performed on samples from other clients exhibited recoveries outside control limits for 1,2-Dichloroethane Method 8260B, Total Phosphorus Method 365.1 and Chemical Oxygen Demand (COD) Method 410.4. Because the corresponding Laboratory Control Samples and the Method Blank samples were within control limits, these anomalies may be due to matrix interference and no corrective action was taken. All other MS/MSD samples were within established control limits. Organics The prepreserved hydrochloric acid preserved vials for Method 8260B analysis for the sample 3406-T01 exhibited pH values greater than 2. This is non-compliant with Method 8260B which requires samples to be preserved with hydrochloric acid to a pH of less than 2. Because this sample is a leachate sample, a buffering effect was suspected. Metals The Method 6010C Continuing Calibration Verification (CCV) sample was above the control limits for Total Sodium. Because the sample 3406-T01 exhibited a detection of Total Sodium greater than ten times the reporting limit, corrective action was deemed unnecessary. The bracketing Continuing Calibration Verification Samples (CCV) surrounding the Method Blank were above control limits for Total Sodium during Method 6010C analysis. Because the data are considered to be biased high and Total Sodium was not detected in the Method Blank sample above the reporting limit, corrective action was deemed unnecessary. 05/23/2017Page 3 of 69 EXECUTIVE SUMMARY - Detections Client: Waste Management Job Number: 280-96675-1 Analyte Result Reporting Limit Units Method Lab Sample ID Client Sample ID Qualifier 280-96675-1 3406-T01 10 ug/L 8260B0.15 J1,2-Dichlorobenzene 3.0 ug/L 8260B4.01,4-Dichlorobenzene 100 ug/L 8260B4.7 J4-Methyl-2-pentanone (MIBK) 100 ug/L 8260B160Acetone 3.0 ug/L 8260B1.9 JBenzene 3.0 ug/L 8260B0.40 JChlorobenzene 5.0 ug/L 8260B0.63 Jcis-1,2-Dichloroethene 5.0 ug/L 8260B2.0 JEthylbenzene 5.0 ug/L 8260B1.2 JToluene 4.0 ug/L 8260B6.0Xylenes, Total SU Field Sampling7.45Field pH umhos/cm Field Sampling3999Field Conductivity Degrees C Field Sampling21.3Field Temperature NTU Field Sampling57.5Field Turbidity mg/L Field Sampling2.1Field Dissolved Oxygen millivolts Field Sampling30.4Field EH/ORP 6.0 mg/L 300.01400Chloride 10 mg/L 300.071Sulfate 20 mg/L 350.1840Ammonia 1.0 mg/L 365.113Phosphorus, Total 500 mg/L 410.4660Chemical Oxygen Demand 5.0 mg/L SM 2320B3100BTotal Alkalinity 5.0 mg/L SM 2320B3100BBicarbonate Alkalinity as CaCO3 40 mg/L SM 2540C3800Total Dissolved Solids 4.0 mg/L SM 2540D29Total Suspended Solids 10 mg/L SM 5310B270Total Organic Carbon - Average 25 mg/L SM5210B48Biochemical Oxygen Demand Total Recoverable 100 ug/L 6010C190BBarium 10 ug/L 6010C80Chromium 10 ug/L 6010C23Cobalt 200 ug/L 6010C45000Calcium 15 ug/L 6010C150Copper 50 ug/L 6010C180Nickel 100 ug/L 6010C11000Iron 20 ug/L 6010C32Zinc 25 ug/L 6010C45Vanadium 200 ug/L 6010C38000Magnesium 10 ug/L 6010C610Manganese 3000 ug/L 6010C280000Potassium 5000 ug/L 6010C1200000B ^Sodium 2.0 ug/L 6020A6.7Antimony 5.0 ug/L 6020A35Arsenic TestAmerica Denver 05/23/2017Page 4 of 69 METHOD SUMMARY Client: Waste Management Job Number: 280-96675-1 Preparation MethodMethodLab LocationDescription Matrix:Water Volatile Organic Compounds (GC/MS)TAL DEN SW846 8260B Purge and Trap TAL DEN SW846 5030B Metals (ICP)TAL DEN SW846 6010C Preparation, Total Recoverable or Dissolved Metals TAL DEN SW846 3005A Metals (ICP/MS)TAL DEN SW846 6020A Preparation, Total Recoverable or Dissolved Metals TAL DEN SW846 3005A Mercury (CVAA)TAL DEN SW846 7470A Preparation, Mercury TAL DEN SW846 7470A Anions, Ion Chromatography TAL DEN MCAWW 300.0 Nitrogen, Ammonia TAL DEN MCAWW 350.1 Phosphorus, Total TAL DEN EPA 365.1 Phosphorus, Total TAL DEN MCAWW 365.2/365.3/365 COD TAL DEN MCAWW 410.4 Nitrogen, Nitrate-Nitrite TAL DEN SM Nitrate by calc Alkalinity TAL DEN SM SM 2320B Solids, Total Dissolved (TDS)TAL DEN SM SM 2540C Solids, Total Suspended (TSS)TAL DEN SM SM 2540D Organic Carbon, Total (TOC)TAL DEN SM SM 5310B BOD, 5 Day TAL DEN SM SM5210B Field Sampling TAL DEN EPA Field Sampling Lab References: TAL DEN = TestAmerica Denver Method References: EPA = US Environmental Protection Agency MCAWW = "Methods For Chemical Analysis Of Water And Wastes", EPA-600/4-79-020, March 1983 And Subsequent Revisions.

The groundwater flow and direction calculations presented in this report are based on groundwater elevation data obtained by ProTech on March 15, 2017. The information provided in this report will satisfy, in part, the environmental reporting requirements of Piedmont Landfill's Municipal Solid Waste Permit. The groundwater level measurements taken during the above referenced sampling event were used to construct the groundwater surface contour map attached to this report as Drawing 1. A summary of groundwater elevations obtained during this and previous sampling events is provided in Table 5. The potentiometric contours and the groundwater flow directions presented in Drawing 1 were used to calculate hydraulic gradients for the site. The hydraulic gradient calculations are provided in Table 6. The hydraulic gradients (i) ranged from 0.018 ft/ft to 0.027 ft/ft. These gradients are generally consistent with past interpretations for the site. An effective porosity value (n) of 41 percent was used in the equation based on an average of six laboratory-derived porosities as reported in the April 1994 Design Hydrogeologic Study, prepared by RUST Environment & Infrastructure. Hydraulic conductivities (K) were also taken from the Design Hydrogeologic Study, and were based on slug test data from piezometers located nearest the respective groundwater flow paths. Using the gradient (i) along each flow path, the linear flow velocity (V) was estimated using the modified Darcy equation: V = i K/n. The flow rate calculations are presented in Table 6. As shown on Drawing 1, groundwater flow at the site is generally to the northwest; however, a hydraulic divide runs through the site such that the local groundwater flow on the northeast side of the landfill is toward the north while groundwater flow on the southwest side of the landfill is toward the southwest. The velocity along the flow segments shown on Drawing 1 were as follows: SEGMENT VELOCITY DIRECTION Segment i1 20.0 ft/yr NW to N Segment i2 10.8 ft/yr W to SW Segment i3 9.6 ft/yr N Segment i4 7.7 ft/yr SW Piedmont Landfill and Recycling Center, Permit # 34-06 Joyce Engineering Groundwater Flow Regime Report May 2017 2 The average groundwater flow rate for the 2017 event was approximately 12.8 feet/year. These groundwater flow directions and velocities are consistent with those calculated during other recent events. The groundwater measurements obtained during the 2017 annual event are generally consistent with those obtained during previous sampling events. Based on this information, it is our opinion that the groundwater monitoring system continues to be adequate for the detection of the release of solid waste constituents to the environment.
