According to NPDES Permit No. WQ0008907, sampling should be completed at the facility in October of each year. However, as indicated in the 2012 report, samples were collected in January 2013 due to a misunderstanding WITH THE Inactive Hazardous Waste Branch (IHWSB). Based on a conversation with the Inactive IHWSB, GCDM was told they did not need to follow any further instruction from NCDENR until the IHWSB got back to them. After conversations with Andrew Pitner in the NCDENR Mooresville office, GCDM realized that the information from the IHWSB was incorrect and they are required to continue sampling per the NPDES permit. GCDM conducted sampling in 2011 and January 2013 to verify the system was operating properly. Moving forward, GCDM will follow the requirements of the permit. GCDM will file to renew the permit in May 2013. If you have questions, please contact Robert Hird at 704-246- 2420 or James Medlin at GCDM at 704-822-5022. . Sincerely, EFI Global, Inc.

Solid Solutions 1.0 INTRODUCTION EFI Global Inc. and A&W Professional Services, PLLC (collectively EFI) prepared this Active Remediation Monitoring Report on behalf of Gaston County Dyeing Machine (GCDMC). This report summarizes current treatment system operational data obtained on January 21, 2013and March 19, 2013. The site is located in the town of Stanley, Gaston County, North Carolina. Figure 1 is a Topographic Map of the property and surrounding area. EFI prepared this report in general accordance with the North Carolina Department of Environment and Natural Resources (NCDENR), Division of Environmental Management (DEM), Non -Discharge Permit Number WQ0008907. The permit requires monitoring wells MW-3, MW-5, MW-7 (formerly MW-713), MW-14 and MW-16 to be sampled in October of each year. Regulatory management of the site was transferred to the Inactive Hazardous Waste Branch (IHWB) in 2010. The IHWB did not require sampling in October 2010-12, however, to meet the requirements of the Non -Discharge Permit, GCDMC requested EFIAo complete the annual sampling. Therefore, EFI conducted the last annual sampling event in January 21, 2013. Please note that MW-7B (intermediate depth well) will be referred to as MW-7 in accordance with the NCDENR, Permits and Compliance Unit. Recently, due to signs of breakthrough during the January 21, 2013 system sampling the carbon was replaced in February 2013 and influent and effluent samples, as well as in-between carbon were collected to evaluate the system performance on March 19, 2013. The spent Carbon was manifested for disposal through OMNI a licensed disposal company. Figure 2 is a Site Map detailing pertinent site features and monitoring well locations. 2.0 ANNUAL GROUND WATER MONITORING EFI measured the depth to the water table in the on -site and off -site monitoring wells on January 21, 2013. The historical static water level measurements and elevation data are presented in Table 1. The static water level measurements at this site indicate the direction of ground water flow is generally toward the west and southwest. Figure 3 is a Potentiometric Map that illustrates the direction of ground water flow. EFT 0 Global Complex Issues • Solid Solutions EFI collected water samples from monitoring- wells MW-3, MW-5, MW-7, MW-14, and MW-16 on January 21, 2013. EFI submitted the ground water samples to Pace Analytical Services, Inc. (Pace) for laboratory analyses for standard pH and volatile organic compounds (VOCs) by EPA Methods 9040 and 624, respectively. According to the laboratory analytical report, tetrachloroethene was detected at concentrations of 6.8 micrograms per liter (ug/1), 9.7 ug/I and 8.5 ug/I in the ground water samples that were collected from monitoring wells MW-3, MW- 14 and MW-16, respectively. A summary of the most recent and historical ground water analytical results are included in Table 2. The laboratory report for the 2013 sampling event is included in Appendix A. Figure 4 is a Tetrachloroethene Concentration Map from the January 2013 sampling event. This map also includes the laboratory analytical results for the influent sample that was collected from recovery well RW-1. According to the report, tetrachloroethene was detected in this sample Below the Detection Limit. The tetrachloroethene concentration that was detected in MW-3 showed up at a low concentration of 6.8 ug/I and the concentrations detected in samples from monitoring wells MW-14 and MW-16.remained relatively stable. See Table 2 and Figure 4 for the tetrachloroethene concentrations. EFI completed the required GW-59 forms for each well and will submitted them to the DEM Groundwater Section, Permits and Compliance Units, as required by the non -discharge permit. Copies of the GW-59 and GW-59A forms are included in Appendix B. 3.0 SYSTEM SAMPLING AND OPERATION AND MAINTENANCE 3.1 System Sampling EFI collected samples from the influent, before the carbon canisters, between the carbon canisters (carbon), and from the effluent on January 21, 2013. During this sampling event the influent sample showed no detectable VOC concentrations however, the between sample showed 5.2 ug/L and the Effluent showed 6.5ug/L present of tetrachloroethene. The sample was immediately shut down and the carbon was replaced in February 2013. The system was F EFI 0 Global Complex Issues • Solid Solutions resampled on March 19, 2013 and no concentrations were detected in the influent, between and Effluent samples and the system was turned back on. The samples were submitted to Pace for laboratory analysis of nitrates, standard pH, and VOCs in accordance with EPA Methods 352.2, 9040, and 624. Additionally, nitrates were not detected at concentrations exceeding the ground water standards in any of the samples collected. Table 3 presents the historic influent and effluent sample analytical results. The laboratory analytical report is provided in Appendix A. 3.2 Operation and Maintenance Between May of 2011 and January 21, 2013, the remediation system operated an estimated 600 days. During the reporting period, approximately 421,561 gallons of water were treated by the remediation system. The total quantity of water that has been treated since remediation commenced at this site is 6,955,728 gallons. The average flow rate for this period was approximately 702.60 gallons per day. The effluent water was injected at an average rate of approximately 1 gallon per minute with the injection well pressure readings generally ranged between 2 and 4 pounds per square inch (psi). The psi is below the injection well permit maximum of 5 psi. During the January sampling event it was determined that the carbon was spent as tetrachloroethene was detected in the between carbon samples and effluent samples. Gaston County then proceeded to shut the system down and replace the spent carbon. Therefore, the system was turned off immediately on January 21, 2013, the system remained off until the carbon was replaced and the system resampled on March 19, 2013. 4.0 CONCLUSIONS AND RECOMMENDATIONS Tetra ch lo roethene (PCE) has historically been detected at concentrations exceeding state standards in ground water samples that have been collected at the site. However, these concentrations have reduced over time in the area of impact near the former lagoon. Recent sampling indicated concentrations of .0068 mg/I in MW-3, .0097mg/I in MW-14 and .0085 in MW-16. No impact was detected of PCE in MW-5 and MW-7 or the influent sample from RW-1. The geometric plume shape has remained fairly stationary and the contaminant concentrations 3 EFI Global Complex Issues • Solid Solutions have been reduced through a combination of natural attenuation and removal by the remediation system. Impact was detected in the January 21, 2013 sampling event that prompted the system to be shut down until the carbon was replaced and resampling confirmed the system operated properly. During the march 19, 2103 sampling event no concentrations of contaminates were detected in the influent, between carbon and effluent samples. CGDM will continue to operate the remediation system until the plume boundaries can be re- established and tetra ch loroethene is reduced sufficiently to justify turning off the remediation system. GCDM will conduct the next monitoring event in October 2013 per the permit requirements. The current NPDES permit expires on November 30, 2013. GCDM will submit a renewal application in May 2013. 5.0 REMARKS The analyses contained in this report represent EFI's professional opinions and are based upon the finding of this investigation and the investigation performed by others.

This report summarizes ground water monitoring and treatment system operational data obtained between January 1, 2010 and May 8, 2011. Also included in the report are the results of annual ground water sampling. The site is located in the town of Stanley, Gaston County, North Carolina. Figure 1 is a Topographic Map of the property and surrounding area. A&W prepared this report in accordance with the North Carolina Department of Environment and Natural Resources (NCDENR), Division of Environmental Management (DEM), Non -Discharge Permit Number WQ0008907. The permit requires monitoring wells MW-3, MW-5, MW-7 (formerly MW-7B), MW-14 and MW-16 to be sampled in October of each year. Regulatory management of the site was transferred to the Inactive Hazardous Waste Branch (H-IWB) in 2010. The IhIWB did not require sampling in October 2010, however, to meet the requirements of the Non -Discharge Permit, GCDMC requested A&W to complete the annual sampling. Therefore, A&W conducted the annual sampling event on April 30, 2011. Please note that MW-7B (intermediate depth well) will be referred to as MW-7 in accordance with the NCDENR, Permits and Compliance Unit. In addition, influent and effluent samples are collected annually to evaluate the system performance. Figure 2 is a Site Map detailing pertinent site features and monitoring well locations. 2.0 ANNUAL GROUND WATER MONITORING A&W measured the depth to the water table in the on -site and off -site monitoring wells on April 30, 2011. The historical static water level measurements and elevation data are presented in Table 1. The static water level measurements at this site indicate the direction of ground water flow is generally toward the west and southwest. Figure 3 is a Potentiometric Map that illustrates the direction of ground water flow. A&W collected water samples from monitoring wells MW-3, MW-5, MW-7, MW-14, and MW-16 on April 30, 2011. A&W submitted the ground water samples to Pace Analytical Services, Inc. (Pace) for laboratory analyses for standard pH and volatile organic compounds (VOCs) by EPA Methods 9040 and 624, respectively. According to the laboratory analytical report, tetrachloroethene was detected at concentrations of 9.5 micrograms per liter (µg/I) and 5.5 µg/1 in the ground water samples that were collected from monitoring wells MW-14 and MW-16, respectively. A summary of the most recent and historical ground water analytical results are included in Table 2. The laboratory report for the 2011 sampling event is included in Appendix A. Figure 4 is a Tetrachloroethene Concentration Map from the April 2011 sampling event. This map also includes the laboratory analytical results for the influent sample that was collected from recovery well RW-1. According to the report, tetrachloroethene was detected in this sample at 5.0 ug/l. The tetrachloroethene concentrations that were detected in samples from monitoring wells MW-14 and MW- 16 and recovery well RW-1 decreased slightly. See Table 2 and Figure 4 for the tetrachloroethene concentrations. A&W completed the required GW-59 forms for each well and submitted them to the DEM Groundwater Section, Permits and Compliance Units, as required by the non -discharge permit. Copies of the GW-59 and GW-59A forms are included in Appendix B. 3.0 SYSTEM SAWLING AND OPERATION AND MAINTENANCE 3.1 System Sampling A&W collected samples from the influent, before the carbon canisters, between the carbon canisters (carbon), and from the effluent on April 30, 2011. The samples were submitted to Pace for laboratory analysis of nitrates, standard pH, and VOCs in accordance with EPA Methods 352.2, 9040, and 624. As previously mentioned, tetrachloroethene was detected at 5.0 µg/l in the influent sample. No VOCs were collected in the samples collected before the carbon canisters, between the carbon canisters, or in the effluent samples. Additionally, nitrates were not detected at concentrations exceeding the ground water standard. However, because the hold time had expired for analyzing the samples for nitrates, A&W collected additional samples from the before the carbon canisters, between the carbon canisters, and after the carbon canisters on May 8, 2011. Nitrates were not detected in these samples at concentrations exceeding the ground water standard. Table 3 presents the historic influent and effluent sample analytical results. The laboratory analytical report is provided in Appendix A. 2 3.2 Oneratio n and Maintenance Between December 31, 2009 and May 8, 2011, the remediation system operated an estimated 456 days out of a possible 493 days. During the annual reporting period, approximately 364039 gallons of water were treated by the remediation system. The total quantity of water that has been treated since remediation commenced at this site is 5,153300 gallons. The average flow rate for this period was approximately 798 gallons per day while the system was operating. The effluent water was injected at an average rate of approximately 0.6 gallons pet minute while the system was operating. Injection well pressure readings generally ranged between 2 and 4 pounds per square inch (psi), were below the injection well permit maximum of 5 psi. 4.0 CONCLUSIONS AND RECOMW DATIONS Tetrachloroethene has historically been detected at concentrations exceeding state standards in ground water samples that have been collected at the site. However, these concentrations have reduced over time in the area of impact near the former lagoon, and have been below the laboratory detection limit in the source area monitoring well (MW-3) for several years. Additionally, the tetrachloroethene concentrations in samples from down -gradient monitoring wells MW-14 and MW-16 continue to decline. The geometric plume shape has remained fairly stationary and the contaminant concentrations have been reduced through a combination of natural attenuation and removal by the remediation system. CGDM will continue to operate the remediation system until the plume boundaries can be re-established and tetrachloroethene is reduced sufficiently to justify turning off the remediation system. GCDM will continue to conduct annual sampling of the ground water and the remediation system. The next annual sampling event is scheduled for October 2012. 5.0 RE3LkRKS The analyses contained in this report represent A&W's professional opinions and are based upon the finding of this investigation and the investigation performed by others. These opinions are arrived in accordance with the currently accepted hydrogeologic and engineering practices at this time and location and no warranties or guarantees are intended or implied. 3 3.2 Operation and Maintenance Between December 31, 2009 and May 8, 2011, the remediation system operated an estimated 456 days out of a possible 493 days.

This report summarizes ground water monitoring and treatment system operational data obtained between November 4, 2008 and December 31, 2009. Also included in the report are the results of annual ground water sampling. The site is located in the town of Stanley, Gaston County, North Carolina. Figure 1 is a Topographic Map of the property and surrounding area. A&W prepared this report in accordance with the North Carolina Department of Environment and Natural Resources (NCDENR), Division of Environmental Management (DEM), Non -Discharge Permit Number WQ0008907. The permit requires monitoring wells MW-3, MW-5, MW-7 (formerly MW-7B), MW-14 and MW-16 to be sampled in October of each year. Please note that MW-7B (intermediate depth well) will be referred to as MW-7 in accordance with the NCDENR, Permits and Compliance Unit. In addition, influent and effluent samples are collected annually to evaluate the system performance. Figure 2 is a Site Map detailing pertinent site features and monitoring well locations. 2.0 ANNUAL GROUND WATER MONITORING A&W measured the depth to the water table in the on -site and off -site monitoring wells on December 23, 2009. The historical static water level measurements and elevation data are presented in Table 1. The static water level measurements at this site indicate the direction of ground water flow is generally toward the west and southwest. Figure 3 is a Potentiometric Map that illustrates the direction of ground water flow. A&W collected water samples from monitoring wells MW-3, MW-5, MW-7, MW-14, and MW- 16 on December 23, 2009. A&W submitted the ground water samples to Pace Analytical Services, Inc. (Pace) for laboratory analyses for standard pH and volatile organic compounds (VOCs) by EPA Methods 9040 and 624, respectively. According to the laboratory analytical report, tetrachloroethene was detected at concentrations of 11.1 micrograms per liter (µg/1), 12.8 µg/,) and 9.8 µg/1 in the ground water samples that were collected from monitoring wells MW-7, MW-14, and MW-16, respectively. A summary of the -- most recent and historical ground water analytical results are included in Table 2. The laboratory report for the 2009 sampling event is included in Appendix A. Figure 4 is a Tetrachloroethene Concentration Map from the December 2009 sampling event. This map also includes the laboratory analytical results for the influent sample that was collected from recovery well RW-1. The tetrachloroethene concentrations that were detected in samples from monitoring wells MW-14 and MW-16 decreased slightly, however the concentration increased in the sample from monitoring well MW-7. Additionally, it was detected in the sample from the recovery well (the influent sample) at 6.3 ug/l. See Table 2 and Figure 4 for the tetrachloroethene concentrations. A&W completed the required GW-59 forms for each well and submitted them to the DEM Groundwater Section, Permits and Compliance Units, as required by the non -discharge permit. Copies of the GW-59 and GW-59A forms are included in Appendix B. 3.0 SYSTEM SAMPLING AND OPERATION AND MAINTENANCE 3.1 System Sgmpling A&W collected samples from the influent, between the carbon canisters (carbon), and from the effluent on December 23, 2009. The samples were submitted to Pace for laboratory analysis of nitrates, standard pH, and VOCs in accordance with EPA Methods 352.2, 9040, and 624. As previously mentioned, tetrachloroethene was detected at 6.3 µg/1 in the influent sample. No VOCs were collected in the samples collected between the carbon canisters and in the effluent samples. Additionally, nitrates were not detected at concentrations exceeding the ground water standard. Table 3 presents the historic influent and effluent sample analytical results. The laboratory analytical report is provided in Appendix A. 3.2 Operation and Maintenance Between October 28, 2008 and December 31, 2009, the remediation system operated an estimated 423 days out of a possible 423 days. During the annual reporting period, 181,226 gallons of water were treated by the remediation system. The total quantity of water that has been treated since remediation commenced at this site is 4,787,964 gallons. The average flow rate for this period was approximately 428 gallons per day while the system was operating. The effluent water was injected at an average rate of r approximately 0.3 gallons per minute while the system was operating. Injection well pressure readings generally ranged between 2 and 5 pounds per square inch (psi), were equal to or below the injection well permit maximum of 5 psi. 4.0 CONCLUSIONS AND RECOMMENDATIONS Tetrachloroethene has historically been detected at concentrations exceeding state standards in ground water samples that have been collected at the site. However, these concentrations have reduced over time in the area of impact near the former lagoon, and have been below the laboratory detection limit in the source area monitoring well (MW-3) for several years. Additionally, the tetrachloroethene concentrations in samples from down -gradient -monitoring wells MW-14 and MW-16 continue to decline. The geometric plume shape has remained fairly stationary and the contaminant concentrations have been reduced through a combination of natural attenuation and removal by the remediation system. CGDM will continue to operate the remediation system until the plume boundaries can be re- established and tetrachloroethene is reduced sufficiently to justify turning off the remediation system. GCDM will continue to conduct annual sampling of the ground water and the remediation system. The next annual sampling event is scheduled for December 2010. 5.0 REMARKS The analyses contained in this report represent A&W's professional opinions and are based upon the finding of this investigation and the investigation performed by others.
