The entire report is provided in pdf for your review. Review of the current analytical results for Appendix I Volatiles indicate all of the monitoring wells and stream samples to be compliant for all hydrocarbon compounds tested with the exception of low level non -compliant vinyl chloride found at 0303T- MW3. Vanadium exceeding 2L IMAC standards was found at 0303T-MW1, 0303T-MW3, and slightly turbid stream samples 0303T-ST1 and 0303T-ST2. Cobalt exceeding 2L IMAC standards was found at 0303T-MW2 and 0303T-MW3. Barium exceeding MCL was found at 0303T-MW3. All other monitoring wells and stream samples revealed compliant metals compounds tested. In a continued evaluation of the low level vinyl chloride contamination present at 0303T-MW3, it appears that the contaminant is stable within a localized area and does not appear to be a threat to human health or the environment. 0303T-MW3 is considered an upgradient background well and is immediately bordered to the north by mountainside. Sparse residential activity is present to the northwest at greater than 500' with no legitimate identifiable source for the contaminant. At this point, it is undetermined as to the source of the vinyl chloride for there have been no historical reported spills or other known incidents in this specific location. Residuals from PVC (poly vinyl chloride) well materials could possibly be a contributive source. The well will continue to be closely monitored and in the event contaminant concentrations significantly increase or begin to appear within down gradient wells, additional hydrogeological analyses or assessment could become necessary. Historical methane monitoring at the site revealed the monitoring wells to contain low level methane readings ranging from 0 to 120 ppm. During this event, all monitoring wells revealed no measurable methane levels and LEL readings were consistent at 0%. No detectable methane levels were found at the scale house or tipping scale area and low level methane ranging from 0 to 30 ppm was found at the recycle center. The methane well, located in the central portion of the landfill, revealed methane concentrations ranging from 40 to 1,020 ppm and a %LEL between 0% and 10%. Methane % volume was calculated at 0.102%. It is recommended that the groundwater/surface water monitoring program continue on a semi-annual schedule. Methane monitoring for all five monitoring wells, the on -site methane well, and enclosed structures will continue on a quarterly basis.

Due to the accumulation of analytical data over several years, the summary has been revised to include the previous three years of data. This event included the sampling of the five monitoring wells (0303T-MW 1 through 0303T-MW5), and two stream samples (0303T-ST1 and 0303T-ST2). Also, methane monitoring was conducted on -site at designated locations. Figure 1 is a Site Map With Monitoring Well And Stream Sample Locations. Review of the current analytical results for Appendix I Volatiles indicate that all monitoring wells and surface water stream samples were found to be compliant for all hydrocarbon compounds tested with the exception of low level non -compliant vinyl chloride in 0303T- MW3 at an estimated 0.67 ppb. The up hydraulic gradient well 0303T- MW3, has historically contained low level non -compliant vinyl chloride and has also revealed non detect levels. It should be noted that due to consecutive compliant 1,4-Dioxane concentrations for all sampling locations, this analysis was previously removed from the sampling program. Appendix I metals barium, cobalt, and vanadium were found during this event at low level non -compliant concentrations. Vanadium exceeding 2L MAC standards was found at 0303T-MW 1 (estimated 0.00043 ppm, 0303T- MW3 (estimated 0.00048 ppm), stream samples 0303T-ST1 (0.0011 ppm) and 0303T-ST2 (estimated 0.00084 ppm). Cobalt exceeding 2L IMAC standards was found at 0303T-MW2 at 0.01041 ppm and 0303T-MW3 at 0.0137 ppm. Barium exceeding MCL was found at 0303T-MW3 at 2.030 July 11, 2022 ppm. All other monitoring wells and surface water stream samples were found to be compliant for all Appendix I Volatiles and Appendix I Metals. Historical results have revealed 0303T-MW1 to contain fluctuating low compliant and non -compliant vinyl chloride and benzene concentrations. Benzene concentrations at 0303T-MW 1 have ranged from below laboratory quantitation limits to 5.02 ppb. Since the June 2011 monitoring event, both the benzene and vinyl chloride concentrations have been found to be none detected. 0303T-MW2 has historically revealed non -compliant methylene chloride concentrations ranging from 5.0 to 17.1 ppb. This event revealed none detected, and methylene chloride has been found to be none detected since June of 2016. 0303T-MW3 has historically shown low level non- compliant vinyl chloride concentrations and none detectable levels. This event and previous event revealed a low level non -compliant concentrations from 1.3 ppb to an estimated 0.67 ppb. Up gradient well, 0303T-MW4 has revealed all compliant concentrations for this event. All compounds have been compliant since December of 2014, with the exception of a non- compliant 2-Hexanone concentration of 55.4 ppb in the December 2015 monitoring event. Concentrations of 2-Hexanone have been complaint or none detected since the June 2016 event, and remain compliant for this event. The down gradient well, 0303T-MW5, located between 0303T-MW1 and Vile Creek, has consistently revealed all target compounds to be compliant, with the exception of the low level non -complaint chloromethane concentration at 6.8 ppb in the December 2016 event; however, this event and the last several results revealed none detected. All other monitoring wells and stream samples collected during this event and previous events were found to be compliant for Appendix I Volatiles. Domestic water supply wells identified on Figure 2 were initially sampled in 2008 and all five were found to be compliant. The closest cross hydraulic gradient well, well#5 was sampled in December, 2012, and was found to remain compliant. The on -site Water Supply Well #1 was sampled during the November 30, 2017 event and analyzed for Appendix I Volatiles only. All compound concentrations were found to be none detected. Methane monitoring was conducted during this event at all five monitoring wells, the on -site methane well, and the enclosed structures identified as the scale house, the recycling center, and the tipping scale area. Non detect methane concentrations were recorded for all monitoring well locations (see Table 1). Historically, low level methane readings have been periodically found in the monitoring wells ranging from 0 to 120 ppm. %LEL and %volume CH4 readings forthe monitoring wells were consistent at 0% during this event. No detectable methane levels were found at the scale house or tipping scale area and low level methane renging from 0 to 30 ppm was found at the recycling/storage center. The methane well, located in the central portion of the landfill, revealed methane concentrations ranging from E July 11, 2022 40 to 1,020 ppm, a % LEL between 0% and 10%, and a % CH4 volume calculated at 0.102%. Results of Well Gauging A Semi -Annual Monitoring Well Data Summary is presented in Table 1. Depth to the groundwater table, as measured on 6/16/22, ranged from 4.96 to 33.44 feet. Sampling Methods and Results (Refer to Tables 2, 3A, 3B, 3C and Appendix A and B) As part of this monitoring event, five monitoring wells, 0303T-MW 1 through 0303T-MW5 were purged of at least three well volumes of groundwater, field measured for parameters pH, temperature, conductivity, turbidity, and sampled. Field measurements are included in Table 1. All groundwater samples collected revealed low turbidity at <5NTUs. Stream samples were found to be slightly turbid ranging from 8.85 to 12.2 NTUs. pH readings were found ranging from 6.23 units at 0303T-MW2 to 5.36 units at 0303T-MW4. Temperatures ranged from 68 F to 69.98 F. All of the monitoring well groundwater samples and stream samples were analyzed by Pace Analytical Services, LLC for Appendix I Volatiles and Appendix I Metals per NC Landfill parameters. 1,4-Dioxane analysis was previously omitted due to consecutive compliant concentrations for all samples collected. The laboratory results are enclosed as Appendix A. Appendix I VOCs Results This event revealed all five monitoring wells (0303T-MW1 through 0303T- MW5), and two stream samples (0303T-ST1 and 0303T-ST2) to be compliant for all Appendix I volatile organic compounds with the exception of an estimated low level non -compliant vinyl chloride concentration (0.67 ppb) found in 0303T-MW3. A Historical Groundwater Sample Results Summary (Appendix I VOCs) is provided in Table 3A. Appendix I Metals Results Appendix I metals barium, cobalt, and vanadium were found during this event at low level non -compliant concentrations. Vanadium exceeding 2L IMAC standards was found at 0303T-MW 1 (estimated 0.00043 ppm, 0303T- MW3 (estimated 0.00048 ppm), stream samples 0303T-ST1 (0.0011 ppm) and 0303T-ST2 (estimated 0.00084 ppm). Cobalt exceeding 2L IMAC standards was found at 0303T-MW2 at 0.01041 ppm and 0303T-MW3 at 0.0137 ppm. Barium exceeding MCL was found at 0303T-MW3 at 2.030 ppm. Monitoring well and stream samples were found to be compliant during c July 11, 2022 this event. A Historical Groundwater Sample Results Summary (Appendix Metals) is provided in Table 3B. Methane Monitoring Results Methane monitoring was conducted at the site utilizing an RKI Instruments Gas Tracer. No measurable methane concentrations were detected in any of the monitoring wells during this event. Historically, the monitoring wells were found to contain low level methane readings ranging from 0 to 120 ppm. LEL and CH4 volume readings were consistent at 0%. The methane well, located in the central portion of the landfill, revealed methane concentrations ranging from 40 to 1,020 ppm, with a %LEL between 0% and 10%. CH4 by volume was measured at 0.102%. In addition, methane monitoring was conducted inside the enclosed structures identified as the scale house, the recycling center/storage area, and the tipping scale area. No measurable methane levels were detected at these locations with the exception of a low level methane reading at the recycle center ranging from 0 to 30 ppm. A Quarterly Methane Monitoring Data Summary is provided in Table 2, and a NCDWM-Solid Waste Section Landfill Gas Monitoring Data Form is provided in Appendix B. 1.2 Proximity of the Plume to the Nearest Receptor (Refer to Figure 2) Sensitive receptors of contamination, as defined by the NCDEQ "include groundwater supply wells and subsurface building structures, as well as any potential for adverse impact to humans, plants, or animals." Five surrounding water supply wells were identified in 2008 by Alleghany County personnel, located within a 500 foot buffer of the former landfill. Figure 2 is a site map that includes the domestic well locations. A summary of surrounding water wells are as follows: WELL OWNER/ WELL MUNICIPAL MUNICIPAL APPROXIMATE # ADDRESS TYPE/ WATER WATER DISTANCE FROM USE AVAILABLE CONNECTION SOURCE AREA OF RELEASE (ft.) 1 Alleghany Co.

Irrigation Sparta, NC 28675 (Inactive) The five surrounding domestic water supply wells were initially sampled in July 2008 and revealed all hydrocarbon concentrations to be compliant. Due to the continued low level vinyl chloride concentrations found at 0303T-MW3, the closest cross hydraulic gradient water supply well, Well #5, was included in the December, 2012 monitoring event and sampled for Appendix I VOCs and Metals. All compounds were found to be compliant. Since that time, Well #5 has remained inactive due to property abandonment. The on -site water supply well, Well #1 was sampled in late November, 2017 and was found to remain compliant. An updated water supply well survey was conducted during a previous event. Wells 1-4 appear to still be in use. Well #5 is on an abandoned property and its building structure is uninhabitable. 1.3 Description of Current Plume Size Historical results have shown varying low level hydrocarbon concentrations of benzene and vinyl chloride exceeding NCAC T:15A 02L Groundwater Standards at monitoring well 0303T-MW1 and 0303T-MW3. Also, 0303T- MW2 has revealed low level methylene chloride and 1,1 dichloroethane concentrations during several previous events above the State action limit. This event revealed all groundwater and surface water samples to be compliant for all Appendix 1 Vocs with the exception of 0303T-MW3 which contained estimated vinyl chloride at 0.67 ppm. The Appendix 1 metals barium, cobalt, and vanadium were found at low level non -compliant concentrations. Vanadium exceeding 2L IMAC standards was found at 0303T-MW 1 ,0303T-MW3, and stream samples 0303T-ST1 and 0303T-ST2. Cobalt exceeding 2L IMAC standards was found at 0303T-MW2 and 0303T- MW3. Barium exceeding MCL was found at 0303T-MW3. 0303T-MW3 Evaluation The contaminant vinyl chloride has been present at times within the surficial groundwater aquifer monitoring well 0303T-MW3. In review of historical data dating back to 2008 and as shown on Figure 3, vinyl chloride was below quantitation limits during the 7/2/2008 sampling event. Starting 12/18/2008 through 12/14/12, non -compliant vinyl chloride concentrations ranging from estimated 0.320 ppb to 1.56 ppb were found to be present within the well. For the following year from 6/19/13 to 6/12/14, no vinyl chloride concentrations were detected. Since that period up to present, the vinyl chloride concentrations have been found from none detected to 1.3 ppb. This event revealed a continued non -compliant vinyl chloride estimated concentration decreasing to 0.67 ppb. It appears that the contaminant is stable within a localized area and does not appear to be a threat to human health or the environment. 0303T-MW3 is considered an upgradient 0 July 11, 2022 background well and is immediately bordered to the north by mountainside. Sparse residential activity is present to the northwest at greater than 500' with no legitimate identifiable source for the contaminant. At this point, it remains undetermined as to the source of the vinyl chloride for there have been no historical reported spills or other known incidents in this location. It is theorized that the contaminant could possibly be associated with residuals from PVC (polyvinyl chloride) well materials. 1.4 Groundwater Flow Direction (Refer to Figure 4) As presented on Figure 4, groundwater flow appears consistent with historical data and remains toward the southeast under the site. 1.5 Predictive Rate of Contaminant Transport As shown on Figure 4, an overall groundwater flow toward the southeast was identified within the area of investigation. A hydraulic gradient (dh/dl) of 4.1 % was calculated between 0303T-MW2 and 0303T-MW4. No slug testing or other hydrogeological testing has been conducted as of this date. In the event contaminant concentrations significantly increase or begin to appearwithin down gradient wells, additional hydrogeological analyses could become necessary. 2.0 CONCLUSIONS AND RECOMMENDATIONS Review of historical results have shown fluctuating low level volatile hydrocarbon compounds meeting and exceeding the NCAC T:15A 02L Groundwater Standards at monitoring wells 0303T-MW1 through 0303T-MW5. Review of the current analytical results for Appendix I Volatiles indicate all of the monitoring wells and stream samples to be compliant for all hydrocarbon compounds tested with the exception of low level non -compliant vinyl chloride found at 0303T-MW-3. Vanadium exceeding 2L IMAC standards was found at 0303T-MW1, 0303T-MW3, and slightly turbid stream samples 0303T-ST1 and 0303T-ST2. Cobalt exceeding 2L IMAC standards was found at 0303T-MW2 and 0303T-MW3. Barium exceeding MCL was found at 0303T-MW3. All other monitoring wells and stream samples revealed compliant metals compounds tested. In a continued evaluation of the low level vinyl chloride contamination present at 0303T-MW3, it appears that the contaminant is stable within a localized area and does not appear to be a threat to human health or the environment. 0303T-MW3 is considered an upgradient background well and is immediately bordered to the north by mountainside. Sparse residential activity is present to the northwest at greater than 500' with no legitimate identifiable source for the contaminant. At this point, it is undetermined as to the source of the vinyl chloride for there have been 9 July 11, 2022 no historical reported spills or other known incidents in this specific location. Residuals from PVC (poly vinyl chloride) well materials could possibly be a contributive source. The well will continue to be closely monitored and in the event contaminant concentrations significantly increase or begin to appear within down gradient wells, additional hydrogeological analyses or assessment could become necessary. Historical methane monitoring at the site revealed the monitoring wells to contain low level methane readings ranging from 0 to 120 ppm. During this event, no measurable methane concentrations were detected at any of the monitoring wells. No detectable methane levels were found at the scale house or tipping scale area and low level methane ranging from 0 to 30 ppm was found at the recycling center. The methane well, located in the central portion of the landfill, revealed methane concentrations ranging from 40 to 1,020 ppm and a %LEL between 0% and 10%. Methane % volume was calculated at 0.102%. It is recommended thatthe groundwater/surface water monitoring program continue on a semi-annual schedule. Methane monitoring for all five monitoring wells, the on -site methane well, and enclosed structures will continue on a quarterly basis. 7 July 11, 2022 3.0 REFERENCES North Carolina Department of Environment and Natural Resources, NC Solid Waste Program.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit MDL -Adjusted Method Detection Limit. Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean -Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis ofAcrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as 'Total' may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes TNI - The NELAC Institute. ANALYTE QUALIFIERS IK The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should be considered an estimated value. v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the associated samples may have a high bias. v2 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the associated samples and the sensitivity of the instrument was verified with a reporting limit check standard. v3 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the associated samples may have low bias.
