(AECOM), on behalf of the City of Raleigh (CoR), has prepared this Leachate Release Soil Sampling Report for the East Wake Transfer Station (Site) located in Raleigh, Wake County, North Carolina. On September 8, 2022, the State of North Carolina, Division of Waste Management Solid Waste Section (SWS) inspected the Site for compliance with North Carolina Solid Waste Statutes and Rules. The NCDEQ issued a Notice of Violation (NOV) to the Site on September 20, 2022. The Site was found to be in violation of 15A NCAC 13B .0405 (a) (10), (b), and (c) and 15A NCAC 13 0.104 (a) through (d). In response, AECOM, on behalf of the CoR, submitted a Response Plan dated September 2022. Soil sampling was performed in accordance with the Response Plan approved by the SWS and the Leachate Release Sampling and Analysis Guidelines (SWS, 2021). Release Incident Pertaining to City of Raleigh The CoR portion of the Site was found to be in violation of 15A NCAC 13B .0405 (a) (10) for a large amount of windblown waste throughout the facility and concealed under plastic sheeting in the riprap along the eastern wall of the transfer station. The CoR portion of the Site violated 15A NCAC 13B .0405 (c) for improper temporary storage. Leaking rolling bins containing waste were stored on the soil adjacent to the access road. Also, transfer vehicles waiting to enter the transfer station tipping floor were leaking leachate, which was running down the access road and accumulating in a low-lying area of the access road. The Site was found to be in violation of 15A NCAC 13 0.104 (a) through (d) for improper solid waste storage. Multiple City of Raleigh plastic rolling garbage bins containing leachate and waste were stored uncovered on a dirt area adjacent to the facility access road to the south of the transfer station building. The area was covered with waste and several dark stains. Soil Sampling Results On October 20, 2022, AECOM properly disposed of all visible waste material and excavated the top 12 inches of soil from the approximate area presented in Figure 1. Approximately 340 bank cubic yards (BCY) were removed from the area a, transported, and disposed at the South Wake County Landfill. After soil removal, AECOM personnel inspected the cut floor for any remaining stains; no stains were observed. Once the excavation operations were completed, AECOM personnel subdivided the excavated area into eight (8) approximately equal parts and collected a discrete sample from the center of each sub -section (Figure 1). A duplicate sample and a background sample were also collected. The background sample (BG-1) was collected upgradient from leachate-impacted areas, and the duplicate sample was collected randomly from one of the sub -sections. A total of ten samples (BG-1, DUP-01, SS-1, SS-2, SS- 3, SS-4, SS-5, SS-6, SS-7, and SS-8) were collected. SS-4 sample exhibited a cobalt concentration that was twice the concentration of all sample locations, including the background location. Therefore, an additional 6 inches (approximately 22 BCY) of soil were removed from the SS-4 sub -section and disposed at the South Wake Landfill, and a second sampling was conducted on November 29, 2022 to reconfirm sampling. A summary of soil sample locations is provided in Table 1, and field notes are provided under Appendix A. Collected samples were labeled, sealed, and placed on ice in coolers for transportation under chain of custody protocol to Eurofins (formerly Environmental Conservation Laboratories, Inc.) for analysis of Volatile Organic Compounds (VOCs) by Test Methods For Evaluating Solid Waste, Physical/Chemical Methods (SW-846) 8260D, 1,4- dioxane by SW-846 8270E selective ion monitoring (SIM) with isotope dilution (ID), metals by SW-846 6010D, mercury by SW-846 7471 B, total phosphorus by Environmental Protection Agency (EPA) Method 365.4, sulfate by SW-846 9056A, nitrate by EPA Method 9056A, and pH by EPA Method 9045D. Soil analytical results were compared to the NCDEQ Preliminary Soil Remediation Goals (PSRGs) — July 2022 and the background sample BG-1. Arsenic, cobalt, and total phosphorus were detected above the NCDEQ PSRGs, but not all exceeded the background sample BG-1. Details of analytes exceedances are summarized below: Arsenic exceeded the Health -Based Residential PSRG in all nine sample locations, including the background location. The arsenic background concentration, 2.7 milligrams per kilogram (mg/kg), was exceeded by three sample locations which included sample locations SS-2, SS-3, and SS-6. Cobalt exceeded the Protection of Groundwater PSRG in all nine sample locations, including the background location, and exceeded the Health -Based Residential PSRG in sample location SS-7. The cobalt background concentration (3.0 mg/kg) was exceeded by seven sample locations which included SS-1, SS-2, SS-3, SS-4, SS- 5, SS-6, and SS-7. Total phosphorus exceeded the Health -Based PSRG and Protection of Groundwater PSRG in all nine sample locations, including the background location. However, the total phosphorus background concentration (640 mg/kg) was not exceeded by any sample locations. A summary of the analytical results is provided in Table 2, and exceedances are shown in Figure 2. The laboratory analytical data report is provided in Appendix B, and a copy of the NCDEQ PSRGs — July 2022 is provided under Appendix C. Conclusions and Recommendations In response to the NOV dated September 20, 2022, the following corrective measures were taken on leachate impacted area investigated by the CoR: • Sanitation operations were moved to the transfer station. • CoR plastic rolling garbage bins containing leachate and waste were processed through the transfer station. • Windblown waste was collected and processed through the transfer station. • 12 inches of topsoil were removed from the leachate-impacted area, and confirmatory soil samples were collected. Arsenic, cobalt, and total phosphorus were detected at concentrations exceeding their respective PSRGs in all nine sample locations, including the background location. The background sample and samples collected from the soil removal area exhibited similar concentrations indicating that the detected concentrations are naturally occurring. Additionally, the Metals and Radionuclides Analyses in Soil Cores from Mooresville, North Carolina investigation led by Dr. Xiaoming Liu (University of North Carolina at Chapel Hill) and Drs. Heather Stapleton and Avner Vengosh (Duke University) showed that cobalt and arsenic concentrations in soil cores collected from six sites near Mooresville, North Carolina were higher than that of the background soil in North Carolina but consistent with cobalt and arsenic concentrations expected in soils overlying Piedmont felsic rocks (Appendix D). Since the Site is located in the Piedmont providence, the soil could be expected to exhibit higher concentrations of arsenic and cobalt naturally. Based on the findings, all detected concentrations at the sample locations appear to be naturally occurring or unrelated to leachate contamination. The analytical results and conclusions indicate that the leachate-impacted area has been properly addressed in accordance with the response plan, and there are no continued hazards to public health and safety. aecom.com Yours sincerely, Jonathan Kucera Senior Engineer/Project Manager jon.kucera@aecom.com cc: Megan Tosches, CoR Stan Joseph, CoR aecom.com Tables Table 1 Soil Sample Summary East Wake Transfer Station Facility Permit No. 9233T-TRANSFER-2008 Raleigh, Wake County, North Carolina Soil Sample Code BG-1 Sample Date 10/20/22 Sample Location Area Background location upgradient from leachate impacted areas SS-1 10/20/22 Impacted soil located southwest quadrant of the Site, generally south of the service road and west of the southern -most storage building SS-2 10/20/22 SS-3 10/20/22 SS-4 10/20/22 SS-5 10/20/22 SS-6 10/20/22 SS-7 10/20/22 SS-8 10/20/22 DUP-01 10/20/22 Notes: 1.

These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported. Method 8260D: The laboratory control sample duplicate (LCSD) for analytical batch 680-748537 recovered outside control limits for the following analytes: 1,2-Dibromo-3-Chloropropane, Acetone and Trichlorofluoromethane. These analytes were biased high in the LCSD and were not detected in the associated samples; therefore, the data have been reported. Method 8260D: The method blank for preparation batch <PrepBatch> contained Acetone above the reporting limit (RL). None of the samples associated with this method blank contained the target compound; therefore, re -extraction and/or re -analysis of samples were not performed. Method 8260D: The method blank associated with analytical batch 680-748537 contained Styrene greater than one-half the reporting limit (RL). The samples could not be re -analyzed because not detected. The sample results have been qualified and reported. Method 8260D: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with analytical batch 680-748537.
