Brooke York, Environmental Engineer, and David Champagne, Environmental Engineer, Region 4 Enforcement and Compliance Assurance Division (ECAD) requested the sampling and laboratory analyses of the piles of auto shredder residues and surface water seepage at the site. Representatives of the LSASD conducted the requested waste and surface water sampling investigation. The following personnel were present for all or a portion of the investigation: NAME ORGANIZATION Paula Whiting Art Masters Mike Neill Brooke York David Champagne Faney Foster Todd Bethune Scott Henson LSASD LSASD LSASD ECAD ECAD Georgia Env. Prot. Div. Georgia Env. Prot. Div. Georgia Env. Prot. Div. DUTIES Project Leader, Safety Officer Sampler Scribe, Sampler Project Manager, Inspector Inspector Inspector Inspector Inspector This sampling event was conducted in accordance with the Sampling and Analysis Plan (SAP) for the TAV Holdings, Inc. facility dated November 19, 2021. Any deviations from the SAP are documented in the field logbook as needed and discussed in the appropriate sections of this report. In addition, the SAP was designed to be used in conjunction with the Applied Science Branch (ASB) Quality Assurance Project Plan December 2019. 2.0 Summary During the TAV Holdings, Inc. sampling investigations, LSASD personnel collected a total of four samples for the Atlanta facility and a total of ten samples for the Greenville facility. The four Atlanta samples and nine Greenville samples were waste samples collected from various locations at the facilities, and one sample was surface water collected from the seep at the toe of the Big Pond. LSASD's Laboratory Services Branch chemists analyzed the samples for total metals and Toxicity Characteristic Leaching Procedure (TCLP) metals. Total metal laboratory analyses showed that nine of the thirteen samples collected from the waste materials contained lead concentrations ranging from 320 mg/kg to 2800 mg/kg and could potentially exhibited the toxicity characteristic (TC) for lead (D008). However, TCLP results for lead exceeded the TC regulatory level of 5.0 mg/l for only one sample. The lead TCLP result was 9.0 mg/l for sample GWA13. LSASD ID: 22-0050 Final Report Page 4 of 126 3.0 Site Background TAV Holdings, Inc. (TAV) has multiple locations in the State of Georgia. TAV operates recycling facilities that use various separation technologies from different industries, as well as a processing and trading of non-ferrous metals. A second Atlanta TAV Holdings, Inc. facility identified is located at 3400 Hamilton Boulevard SW in Atlanta, Georgia. This TAV facility was leased but is no longer in operation. This facility was used as a research and development site prior to the Empire Road facility startup. The property reverted to the original owners, but still store abandoned automobile shredder residue (ASR) material from the TAV operations. TAV also has a facility located at 56 Jarrell Road in Greenville, Georgia. This TAV facility operation include offices, the Shop (an open sided metal building), Runway 1 and 2 Piles of ASR material, the Ball Mill and processed ASR pile, a settling pond, the Big Pond and the Big Waste Pile. The TAV facility receives ASR, fluff generated from the shredding of automobiles, various stages of ASR in the recovery process, and previously landfilled ASR from multiple offsite sources. This material received would normally be disposed of in solid waste landfills. TAV Greenville operates a recycling facility that uses various separation technologies for different industries, as well as a processing and trading company of non-ferrous metals. The US EPA and Georgia Environmental Protection Division (GAEPD) inspectors were informed that the incoming material is received at no cost to TAV. All the material received for processing at TAV are solid waste. This solid waste received is stored outside upon delivery. The solid waste is seperated based on particle size and undergoes several screening and particle size reduction processes to recover metals, primarily copper. As the solid waste is processed, material not high enough in recovered metals, to be sold for recovery or smelting, is being stored onsite. TAV Greenville plans to send this waste for off-site disposal at the Turkey Run Landfill. No disposal records of any of the wastes generated from the processing of the ASR have been provided. TAV Greenville currently holds a National Pollutant Discharge Elimination System (NPDES) industrial stormwater permit from GAEPD. The US EPA was originally contacted concerning NPDES violations that were occuring at the TAV Empire Road facility. TAV Greenville facility recovers metals from the ASR. However, there are numerous piles of the processed ASR material stored on the ground throughout the facility. In addition, the facility operates a process water treatment system, where the process water is sent to a system of settling ponds and then back into the process. Studies, completed by the US EPA, report that auto shredder residues may contain lead, cadmium, and chromium. ECAD has requested LSASD to collect samples to determine if the ASR and processed materials with metal contaminants are being properly managed and/or if contaminants are potentially leaving the site. LSASD ID: 22-0050 Final Report Page 5 of 126 4.0 Field Investigation and Methodology On November 30, 2021, the US EPA and GAEPD conducted a case development investigation evaluation (CDIE) at TAV Holdings, Inc., 3400 Hamilton Boulevard, SW in Atlanta, Georgia. LSASD conducted an authoritative sampling investigation by collecting four waste samples. Sample locations were based on observations at the time of the investigation. The US EPA inspectors and LSASD field investigators surveyed the facility initially to determine where to collect samples. During the November 30, 2021 CDIE, the US EPA and GAEPD investigators observed a building with a pit area filled with liquid and sediment. Next to the building were three large totes and two small totes suspected to contain used sulfuric acid. LSASD attempted to screen one large tote with pH paper to determine corrosivity. However, results were inconclusive because of color interference with the liquid. Next to the totes was an open fractionation tank with several inches of sediment in the bottom. In the center of the facility were three large ASR piles containing metal chunks and various debris. The piles started near the property fence and stretched almost 200 feet towards the rear of the property. Between the first two piles was liquid that had runoff and was ponding. On the northeast side of property fence was a large pile of ASR fines that appeared to be solid but once stepped upon shifted and then collapsed under weight. The investigators observed that the ASR fines pile was multi-phased with liquid flowing between the fines. However as the investigators moved away from the large ASR fines pile toward the front of the property, the ASR fines were dried with cracks and observed to have flowed under the property fence to the public sidewalk and the city right of way. ECAD requested that LSASD sample the pit area filled with liquid and sediment, the large ASR piles with metal and various debris, the ASR fines pile and the ASR material outside of the property fence. LSASD personnel sampled liquid and/or solids from the pit area, the large ASR piles, the ASR fines pile and the material released outside the property fence (AWA01, AWA02, AWA03, and AWA04). Chain of custody documents were prepared by Mr. Neill using the US EPA's Scribe program. Samples were submitted to the LSASD laboratory for analyses. Split samples were collected by LSASD and were provided to Mr. Robert Brewer, TAV Holdings, Inc. on November 30, 2021, at 2:18 PM. On December 1, 2021, the US EPA and GAEPD conducted a CDIE at TAV Holdings, Inc. in Greenville, Georgia. LSASD conducted an authoritative sampling investigation and collected nine waste samples and one surface water sample. Sample locations were based on observations at the time of the investigation. The US EPA inspectors and LSASD field investigators surveyed the facility initially to determine where to collect samples. During the CDIE, the US EPA and GAEPD investigators observed Runway 1 and Runway 2 Piles. Mr. Tim Good, Jr., TAV, explained that Runway 1 Pile contained oversized ASR material that got screened first and then shredded to a smaller size, while Runway 2 Pile was processed ASR material. Across from Runway 2 Pile was the Settlement (Settling) Pond which held piles of dark brown LSASD ID: 22-0050 Final Report Page 6 of 126 multi-phase sediment mixed with debris and liquid. Mr. Good explained that this material is reused in the process. The investigators then followed the path of the process water as it exited and then enter the operations. The runoff from the process and the facility flows between Runway 1 and Runway 2 piles into a settling swale next to the Big Pond. Majority of the sediment drops out into the settling swale. The runoff liquid flows into the Big Pond for additional settling before being pumped to the Concrete Pond. The liquid is then returned to the process. The Concrete Pond holds the spray bar water from the Big Pond. The Big Pond captures all the runoff water, process water and stormwater from the facility. During the investigation, the investigators observed a seep on the north side of the Big Pond. The seep released into a wooded area and has created a runoff path further into the wooded area. Near the entrance of the facility are office buildings, a large open-end building called the Shop and the Ball Mill with in-process ASR piles, and the Ball Mill settling pond. Behind the Ball Mill is a very large pile of discarded ASR material stored onsite. This pile, according to Mr. Good, needs to be disposed of at the Turkey Run Landfill. At the base of the big ASR waste pile is a pond collecting runoff liquid and sediment. The investigators walked the property border to determine runoff paths with potential releases to the environment. The investigators noted that the back side of Runway 1 Pile is bordered by a runoff stream and a capped landfill. ECAD requested that LSASD sample the Settlement (Settling) Pond 1, Big Pond Settling Swale, Big Pond near the inlet, Ball Mill Settling Pond mud pile, Big Waste Pile toe pond, Runway 1 Pile heel pond and the Big Pond seep at the toe slope. LSASD personnel sampled liquid and/or solids from the Settlement (Settling) Pond 1, Big Pond Settling Swale, Big Pond near the inlet, Ball Mill Settling Pond mud pile, Big Waste Pile toe pond, Runway 1 Pile heel pond (GWA05, GWA06, GWA07, GWA08, GWA09, GWA10, GWA11, GWA12, and GWA13), and surface water sample from Big Pond toe slope seep into the wooded area (GSW01). Field activities were conducted in accordance with LSASD's Field Branch's Management and Quality System Procedures and the following LSASD field sampling operating procedures: LSASDPROC-302-R4, Waste Sampling LSASDPROC-201-R4, Surface Water Sampling All field measurement and sampling procedures were performed and/or overseen by LSASD Field Services Branch personnel proficient in the pertinent procedures. Any person that was not proficient in any measurement or sampling procedure was teamed with someone who was proficient. Chain of custody documents were prepared by Mr. Neill using the US EPA's Scribe program. Samples were submitted to the LSASD laboratory for analyses. Split samples were collected by LSASD and were provided to Mr. Brent Fairchild, TAV Holdings, Inc. on December 1, 2021, at 5:30 PM. LSASD ID: 22-0050 Final Report Page 7 of 126 Sample data collected during the investigation are presented in Table 1 and Table 2. Photographs are in Appendix A. 5.0 Results and Discussion The environmental sample (GSW01) and waste samples (AWA01, AWA02, AWA03, AWA04, GWA05, GWA06, GWA07, GWA08, GWA09, GWA10, GWA11, GWA12 and GWA13) were analyzed for total metals using USEPA method 6010C and USEPA method 200.8. When total metal scan results showed that one of the TC constituents in a sample could possibly exceed its TC regulatory levels, the TCLP was performed for that sample. The TCLP was performed on ten waste samples using US EPA method 1311 and the TCLP extracts were analyzed for TC metals. Table 3, Table 4 and Table 5 summarize the Total Metals -Data Summary, and Table 6 and Table 7 summarize the TCLP metal analyses for the waste samples. LSASD's complete analytical reports are included as Appendix D. As expected, metal scans of the waste samples showed high concentrations of copper and other metals including aluminum, iron, lead and zinc. Analyses showed that the waste samples that were solids or multi-phased contained copper ranging from 39 mg/kg to 67000 mg/kg, aluminum ranging from 4600 mg/kg to 42000 mg/kg, iron ranging from 16000 mg/kg to 44000 mg/kg, lead ranging from 320 mg/kg to 2800 mg/kg, and zinc from 200 mg/kg to 9200 mg/kg (Tables 3 and 4). Sample AWA04 which was collected from the public sidewalk outside the fence at the TAV Atlanta facility contained 2500 mg/kg of lead. Note: The TAV Atlanta facility is located in an industrial park with worker and public access. This lead concentration exceeds both the 400 mg/kg USEPA Regional Screening Level (RSL) for lead compounds from the Resident Soil Table (TR=1E-06, HQ=0.1) November 2021 for noncarcinogenic SL Child, THI=0.1, and the 800 mg/kg RSL for lead from Composite Worker Soil Table (TR=1E-06, HQ=1) November 2021 for noncarcinogenic SL, THI=1. Based on concentrations of TC metals obtained during the total metal scans, ten samples were extracted for the TCLP. However, TCLP results for lead exceeded the TC regulatory level of 5.0 mg/l for only one sample. The lead TCLP result was 9.0 mg/l for sample GWA13 (Table 7). The other five samples from the TAV Greenville facility had lead TCLP results ranging from 0.87 mg/l to 2.9 mg/l while the four samples from the TAV Atlanta facility had lead TCLP results ranging from 3.7 mg/l to 4.5 mg/l. Quality Control Sample Results Blanks (Field and Equipment) No field or equipment blanks were collected during this investigation. A temperature blank accompanied the environmental sample and arrived at the laboratory at 3.4 C. LSASD ID: 22-0050 Final Report Page 8 of 126 Split Samples Split samples were collected at each sample station and were provided to the facility for shipment to and analysis at their contract laboratory. The copy of the signed Receipt for Samples is in Appendix C. Laboratory Quality Control Samples For the total metal analyses, samples AWA04 and GWA11 were designated as the LSASD's laboratory matrix spike/matrix spike duplicate (MS/MSD), and for the TCLP analyses, sample AWA03 was used as the quality control sample. Results of quality control analyses are contained in the LSASD's Laboratory Analytical Data Reports in Appendix D and are acceptable for the purposes of this investigation. Full definitions for the data qualifiers are provided in their respective reports. The reported results are accurate within the limits of the methods. 6.0 Conclusions Laboratory analyses showed high concentrations of metals in the processed materials but only one of the thirteen waste samples (GWA13) was shown to exhibit the toxicity characteristic for lead (D008) with a lead TCLP result of 9.0 mg/l. The analytical data from this sampling investigation indicate that the TAV Holdings' activities and operations could potentially impact environmental media at both sites due to ASR with high concentrations of metals being stored on the ground. 7.0 References US EPA LSASD.

MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and reported with a 99% confidence that the analyte concentration is greater than zero. MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and moisture content of soil/sediments. TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the estimated concentration reported.

This report shall not be reproduced except in full without approval of the Region 4 laboratory. These analyses were performed in accordance with the Laboratory Services Branch's Laboratory Operations and Quality Assurance Manual (LSB LOQAM) found at www.epa.gov/region4/sesd/asbsop. Any unique project data quality objectives specified in writing by the data requestor have also been incorporated into the data unless otherwise noted in the Report Narrative. Chemistry data have been verified based on the LSB LOQAM specifications and have been qualified by this laboratory if the applicable quality control criteria were not met. Verification is defined in Chapter 5 of the LSB LOQAM. For a listing of specific data qualifiers and explanations, please refer to the Data Qualifier Definitions included in this report. The reported results are accurate within the limits of the method(s) and are representative only of the samples as received by the laboratory.

Id: 22-0050 Project: 22-0050, TAV Holdings, Inc. - Greenville, GA - Reported by Stephanie McCarthy Report Narrative for Project: 22-0050 Analysis: TCLPM Four samples were not analyzed for TCLP because the total metal results were below the TCLP Fail Threshold / screening concentrations (i.e., samples cannot exceed TCLP regulatory levels based on the total scan analyses). Sample Disposal Policy Due to limited space for long term sample storage, LSB's policy is to dispose of samples on a periodic schedule. Air samples collected in summa canisters will be disposed of 30 days following the issuance of this report. All other sample media including original samples, sample extracts and or digestates will be disposed of, in accordance with applicable regulations, 60 days from the date of this report. This sample disposal policy does not apply to criminal samples which are held until the laboratory is notified by the criminal investigators that case development and litigation are complete. These samples may be held in the laboratory's custody for a longer period of time.

The identification of the analyte is acceptable; the reported value is an estimate. Matrix Spike Recovery less than method control limits ACRONYMS AND ABBREVIATIONS CAS Chemical Abstracts Service Note: Analytes with no known CAS identifiers have been assigned codes beginning with "E", the EPA ID as assigned by the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R4-", a unique identifier assigned by the EPA Region 4 laboratory. MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and reported with a 99% confidence that the analyte concentration is greater than zero. MRL Minimum Reporting Limit - Analyte concentration that corresponds to the lowest demonstrated level of acceptable quantitation. The MRL is sample-specific and accounts for preparation weights and volumes, dilutions, and moisture content of soil/sediments. TIC Tentatively Identified Compound - An analyte identified based on a match with the instrument software's mass spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the estimated concentration reported.
