The property at 288 Whitehouse Dr, Lincolnton, NC is the site where Celadon Recycling Services formerly operated a Centralized Waste Treatment facility. Among other things, Shield was engaged to investigate and characterize the water quality and sludge material in an 0.81 acre pond ("Pond") and a 300,000 gallon open -top holding tank, referred to as the equalization tank ("Tank") on the property. See attached photographs. The effort, as described below, required Shield to conduct a sampling program and obtain EPA -certified laboratory analysis of the Pond water, sludge, and wastewater from the Tank. This report presents the results of the analytical program related to those conditions on the property and describes site features, Shield's field procedures, laboratory testing protocols and a summary of findings. Copies of the laboratory results from eurofins TestAmerica are provided as an Attachment. Analytical Report ID 400- 203460-1 addresses water samples from the Pond (Sample ID W-1) and from the Tank (Sample ID EQ-1). The second, Analytical Report ID 400-203461-1, addresses the results of a five -sample composite sample of the sediment/sludge from the Pond (Sample ID S1-5 Composite). SUMMARY FINDINGS • Very few analyzed constituents were detected in the Tank and Pond samples. Detected constituent concentrations in the samples are considered relatively low. No constituent was found at amounts that would cause the waters to be considered hazardous waste. No constituents were detected at levels that exceed common regulatory thresholds such as US EPA Regional Screening Levels, US EPA Maximum Contaminant Levels, and North Carolina surface and groundwater standards used for context. • In general, as with the water samples, few analyzed constituents were detected in the sludge. All the TCLP results for both organics and metals were reported as "ND" (Not SHIELD ENGINEERING Results of Pond and Tank Sampling Celadon Recycling Solutions Shield Project No. 1210037-01 July 23, 2021 Page 2 Detected at the reporting limit) indicating that the sludge did not contain detectable concentrations of D-Listed hazardous waste. Sampling Methodologies/Volumes Sampling of the Pond water, identified in the lab reports as "W-1", and the Tank, referred to as "EQ-111, as well as sludge from the pond, referred to as "S1-5 Composite", was conducted on May 13, 2021. Sampling, sample handling, and chains of custody were conducted in accord with standard methods. Water samples from the Pond were obtained in the nominal center at approximately 1 foot below the surface by Shield's sampling crew working out of a flat -bottom boat. The Tank, which is continuously mixed by pump recirculation therefore keeping solids in suspension, was sampled at the top from the exterior access ladder. The Pond bottom sludge samples were obtained by Shield's field crew at five representative locations in the Pond and were taken from the boat and from the catwalk on the east end of the Pond. The boat was held stable at each location by tethering to polypropylene ropes crossing the water at fixed locations and tied to the security fence that surrounds the Pond. A stainless - steel sampling dredge (clam shell sampler) was used to obtain each of the five sludge samples. For volume calculations, using a graduated rod and measuring tape, representative water -depth and sludge -thickness measurements were obtained at eight locations. The Pond water depth was determined to be nominally 6 feet to the top of the sludge. Water volume of the Pond is estimated to be 1.2 million gallons and is variable due to precipitation and evaporation. The sludge measured approximately 6 inches deep across the Pond and is estimated to be about 500 cubic yards. The Tank contains approximately 300,000 gallons. SHIELD ENGINEERING Results of Pond and Tank Sampling Celadon Recycling Solutions Shield Project No. 1210037-01 July 23, 2021 Page 3 In accordance with standard field sampling methods, the separate water samples were placed into laboratory -prepared containers. The separate sludge samples were also placed in laboratory -prepared containers and all samples were packed on ice in insulated containers and sent overnight to a U.S. EPA -certified laboratory, eurofins TestAmerica. The sludge samples were composited at the analytical laboratory into one sample. Both water and sludge samples were laboratory analyzed for a wide spectrum of analytes as described below. Laboratory Analyses All laboratory analysis were conducted by U.S. EPA SW-846 for RCRA testing under 40 C.F.R. § 260.11. The water samples were analyzed for volatile organic compounds (VOCs) by EPA Method 8260D, semi -volatile organic compounds (SVOCs) by EPA Method 8270E. The eight RCRA metals by EPA Method 6010D and Method 7470A (mercury), along with selected wastewater parameters - pH, temperature, ammonia, biochemical oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solids (TSS). As a conservative measure to identify other potential problematic analytes, we broadened the analysis to include organochlorine pesticides by EPA Method 8081B, and herbicides by EPA Method 8151A. The Pond sludge sample was also analyzed for a wide spectrum of analytes including VOCs, SVOCs, pesticides, herbicides, and eight RCRA metals. In addition, the sludge sample was analyzed using EPA Method 1311 Toxicity Characteristics Leachate Procedure (TCLP) for VOCs, SVOCs, pesticides, herbicides, and metals. TCLP results provide leachable values that can be used to determine if a waste is hazardous by the toxicity characteristic under 40 C.F.R. § 261.24. Pond W-1 and Tank EQ-1 Water Lab Results Summary As demonstrated, over 95 percent of the analytes, including the pesticides and herbicides, tested in the waters were not detected above the reporting limit (non -detected or "ND.") Of the SHIELD ENGINEERING Results of Pond and Tank Sampling Celadon Recycling Solutions Shield Project No. 1210037-01 July 23, 2021 Page 4 approximately 150 organic constituents analyzed, only seven were detected in the Pond sample and nine in the Tank sample. Only two out of eight metals, mercury and barium, were detected in the Pond and the Tank samples. The Tank and Pond results are generally similar with the exception being that the Tank sample has higher TSS (due to constant recirculation of water) and COD than the Pond sample. The results for these limited constituents that were detected and comparison to US EPA Regional Screening Levels and various water quality standards for context are presented in Table 1. As illustrated in Table 1, detected organic constituent concentrations are considered low with all but one result (benzoic acid) in the micrograms per liter (µg/I aka parts per billion (ppb)) range. Numerous detections were so low that they triggered "J" qualifiers signifying the results, while higher than the method detection limit, are below the reporting limit and, therefore, are estimated values. These results differ slightly in both constituents and amounts from results from samples conducted by the North Carolina Department of Environmental Quality (NCDEQ) in January 2021. However, the sampling locations and methods used for those investigations are not clear, and so Shield relies on its more recent and documented sampling to reflect the current conditions. Importantly, referring to Table 1, no constituent was found at amounts that would cause the waters to be considered hazardous waste. Another conclusion of the testing program is, except for benzoic acid exceeding the NCDEQ groundwater standard in sample EQ-1, the absence of any constituent at levels that exceed common regulatory thresholds such as US EPA Regional Screening Levels, US EPA Maximum Contaminant Levels, and other water quality standards. It is important to note that benzoic acid as well as several other detected constituents have few or no standards in the aforementioned programs, further indicating relatively low toxicity risk of those constituents. Finally, while a few of the parameters (e.g., BOD, COD, and TSS) are at levels that exceed the nominal local limits for discharge to the Lincolnton publicly owned treatment SHIELD ENGINEERING Results of Pond and Tank Sampling Celadon Recycling Solutions Shield Project No. 1210037-01 July 23, 2021 Page 5 works, the levels are well within the range that could be accepted if done so with proper testing on a planned schedule and payment structure. Pond Sludge (S-1) Laboratory Results Summary In general, as with the water samples, relatively few analyzed constituents were even detected in the sludge. Of the approximately 150 organic constituents analyzed, only seven were detected in the sludge composite sample, all at low levels. Metals detected were barium, chromium, lead and mercury, again at low levels. All the TCLP results for both organics and metals were reported as "ND" indicating that the sludge did not contain detectable concentrations of D-Listed hazardous waste. 40 C.F.R. §261.24. Furthermore, levels detected are below the EPA's Regional Screening Levels for industrial soil and below the levels recognized by the NCDEQ standards for Industrial/Commercial Health -Based Preliminary Soil Remediation Goals. The laboratory results and comparisons for the sludge analysis are provided in Table 2. Conclusions In Shield's opinion, the minor detection of organic compounds and metals in both the water samples and the sludge samples does not warrant these materials being characterized as hazardous waste. The results show the water and sludge samples are within the limits generally acceptable for disposal by discharge to a publicly owned treatment works (water) or in a municipal, non -hazardous landfill (sludge), subject to the requirements of the Pretreatment Coordinator or the landfill permit for water and sludge, respectively.

Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved and on ice. The temperature of the cooler at receipt was 0.00 C. GC/MS VOA Method 8260D: The laboratory control sample (LCS) for analytical batch 400-532736 recovered outside control limits for the following analyte: Hexachlorobutadiene. This analyte was biased high in the LCS and was not detected in the associated samples; therefore, the data have been reported. Method 8260D: The continuing calibration verification (CCV) associated with batch 400-532736 recovered above the upper control limit for Bromomethane, Hexachlorobutadiene and n-Butylbenzene . The samples associated with this CCV were non -detects for the affected analyte; therefore, the data have been reported. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. GC/MS Semi VOA Method 8270E: The following samples were diluted due to the nature of the sample matrix: W-1 (400-203460-1) and EQ-1 (400-203460-2). Elevated reporting limits (RLs) are provided. Method 8270E: Surrogate recovery for the following sample was outside control limits: EQ-1 (400-203460-2). Evidence of matrix interference is present; therefore, re -extraction and/or re -analysis was not performed. Method 8270E: The continuing calibration verification (CCV) associated with batch 400-532781 recovered outside acceptance criteria, low biased, for Bis(2-chloroethyl)ether, Caprolactam, Nitrobenzene, Isophorone, Phenol, and Bis(2-chloroethoxy)methane. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Since the associated samples were less than the reporting limit for this analyte, the data have been reported. Method 8270E: Six surrogates are used for this analysis. The laboratory's SOP allows one of these surrogates to be outside acceptance criteria without performing re-extraction/re-analysis. The following sample contained an allowable number of surrogate compounds outside limits: W-1 (400-203460-1). These results have been reported and qualified. Method 8270E: The continuing calibration verification (CCV) associated with batch 400-532788 recovered above the upper control limit for Carbazole and Bis(2-ethylhexyl) phthalate. The samples associated with this CCV were non -detects for the affected analytes; therefore, the data have been reported. The associated samples are impacted: (CCVIS 400-532788/3) and (MB 400-532580/1-A). No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. GC Semi VOA Method 8081 B: The continuing calibration verification (CCV) associated with batch 400-532257 recovered above the upper control limit for 4,4'-DDT. The samples associated with this CCV were non -detects for the affected analytes; therefore, the data have been reported. Method 8081 B: Two surrogates are used for this analysis. The laboratory's SOP allows one of these surrogates to be outside acceptance criteria without performing re-extraction/re-analysis. The following samples contained an allowable number of surrogate compounds outside limits: W-1 (400-203460-1) and EQ-1 (400-203460-2). These results have been reported and qualified.

Job ID: 400-203460-1 Method 8081 B: The laboratory control sample duplicate (LCSD) recovered above calibration range for the following analytes: 4,4'-DDT and Methoxychlor. However, the percent recoveries (%R) are within acceptance limits; therefore, the data has been reported. (LCSD 400-532015/3-A) No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. Metals Method 7470A: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 400-531709 and analytical batch 400-532149 were outside control limits. Sample matrix interference and/or non -homogeneity are suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits. Method 6010D: Method required MS/MSD and/or duplicate QC were prepared and analyzed at required batch frequency for preparation batch 400-532043 and analytical batch 400-532226 using samples from other sites, and are not reported with this project. Method 6010D: The continuing calibration verification (CCV) associated with batch 400-532226 recovered above the upper control limit for Arsenic, Chromium and Selenium. The samples associated with this CCV were non -detects for the affected analytes; therefore, the data have been reported. The associated samples are impacted: W-1 (400-203460-1), EQ-1 (400-203460-2) and (MB 400-532043/1-A). No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. General Chemistry Method SM 5220D: The following samples were diluted to bring the concentration of target analytes within the calibration range: W-1 (400-203460-1) and EQ-1 (400-203460-2). Elevated reporting limits (RLs) are provided. Method SM 5220D: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for analytical batch 400-532002 were outside control limits. Sample matrix interference and/or non -homogeneity are suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits. Method 350.1: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for analytical batch 400-532312 were outside control limits. Sample matrix interference and/or non -homogeneity are suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits. Method 350.1: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for analytical batch 400-532313 were outside control limits. Sample matrix interference and/or non -homogeneity are suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits. Method 350.1: The following samples were diluted to bring the concentration of target analytes within the calibration range: W-1 (400-203460-1) and EQ-1 (400-203460-2). Elevated reporting limits (RLs) are provided. Method SM 5210B: The glucose-glutamic acid standard (LCS) recovered outside the recovery limits specified in the method in batch 400-531930. The method holding time had expired, therefore the analysis was not repeated. The data was qualified and reported.

Receipt The samples were received on 5/15/2021 10:31 AM. Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved and on ice. The temperatures of the 2 coolers at receipt time were 0.00 C and 0.00 C. GC/MS VOA Method 8260D: The continuing calibration verification (CCV) associated with batch 400-532492 recovered outside acceptance criteria, low biased, for 1, 1 -Dichloroethene. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Since the associated samples were non -detect for this analyte, the data have been reported. Method 8260D: Due to the TCLP extraction process, the following sample was diluted X5: S1-5 COMPOSITE (400-203461-6). Method 8260D: The continuing calibration verification (CCV) associated with batch 400-532534 recovered above the upper control limit for Isobutyl alcohol. The samples associated with this CCV were non -detects for the affected analytes; therefore, the data have been reported. Method 8260D: The matrix spike duplicate (MSD) recoveries for preparation batch 400-532586 and analytical batch 400-532534 were outside control limits.
