The subject property is identified by the Mecklenburg County GIS website as Parcel identification Number (PIN) 12703509 and owned by CC Elizabeth on Seventh LLC. The subject property is a North Carolina Department of Environmental Quality (NCDEQ), Division of Waste Management (DWM), Brownfields Program site. The Brownfields assigned project name is Seventh Street Properties and has the Brownfields Project No. of 24004-20-060. Currently the site is undergoing redevelopment. Throughout the site grading/redevelopment activities, a total of 8 previously unknown underground storage tanks (USTs) were encountered. In accordance with the approved Environmental Management Plan (EMP) which was approved on April 23, 2020 for the site, the USTs were documented, removed, and samples were collected from the UST excavations. This letter report documents the UST removal activities and presents the laboratory data and disposal documentation. 2.0 UST REMOVAL SERVICES On September 88, 2020 ECS observed and documented the removal of one 550-gallon UST by Choate Construction (Choate), the on-site general contractor. ECS subcontracted Contaminant Control Inc. Environmental Services (CCI) to remove the contents of the UST prior to removal, and to transport the UST and contents for off-site disposal. Following the removal of the UST and based on the length of the UST (i.e., less than 10 feet), ECS collected one soil sample (TS-1) beneath the location of the former UST. The approximate location of the UST is indicated on Figure 2. On January 25, 2021 ECS observed and documented the removal of four additional USTs. One of the USTs was approximately 300-gallons and was paired with an approximately 50-gallon UST that was believed to be part of a hydraulic lift reservoir (located above the 300-gallon UST). The other two USTs were approximately 550-gallons in size. Each of the USTs were located in the eastern corner of the site near the intersection of East 7th St and North Caswell Rd and were removed by Choate. ECS subcontracted CCI to remove the contents of the USTs prior to removal, and to transport the USTs and contents for off-site disposal. Following removal of the USTs, based on size and locations, ECS collected three soil samples. One beneath the former location of each of the 550-gallon USTs (T-1 and T-3, and one beneath the 300-gallon UST (T-2). The approximate location of the USTs is indicated on Figure 2. On January 29, 2021 ECS observed and documented the removal of two more USTs thought to be associated with another hydraulic lift reservoir. The larger UST was approximately 300-gallons in size, and the smaller UST was approximately 50-gallons. The USTs, including remaining liquids inside were removed by Choate and staged onsite (placed on and covered with plastic). Following removal, ECS collected one soil sample (T-4) from the area beneath the USTs. ECS subcontracted CCI to remove the remaining product in the USTs and transport the USTs and contents for off-site disposal on February 8, 2021. The approximate location of the USTs are indicated on Figure 2. Underground Storage Tank Removal Letter Report Seventh Street Properties Brownfields Project No. 24004-20-060 East 7th Street & North Caswell Road Charlotte, Mecklenburg County, North Carolina ECS Project No. 49:8832-C September 8, 2021 2 On February 1, 2021 ECS observed and documented the removal of one approximately 700-gallon UST by Choate, which was staged with the previously mentioned 300-gallon UST and 50-gallon UST. Following the removal of the tank and based on the size, ECS collected one soil sample (T-5) from the area below the UST. The 700-gallon UST was removed by CCI for off-site disposal on February 8, 2021. The approximate location of the UST is indicated on Figure 2. Photographs taken during the various UST removal activities are included in Appendix A and disposal manifests for the removed contents and the USTs are included in Appendix B. Each soil sample was collected from a depth of approximately 8 feet below the ground surface. Approximately one to two feet of soil was removed from the base of each UST prior to the collection of the soil samples. Groundwater was not encountered during the removal of the USTs. Each of the soil samples collected from the base of the UST excavations were submitted to either Pace Analytical Services, LLC or Waypoint Analytical, both of which are North Carolina certified laboratories. In accordance with the approved EMP, the soil samples were submitted for laboratory analysis of volatile organic compounds (VOCs) using EPA Method 8260, semi-volatile organic compounds (SVOCs) using EPA Method 8270, Resource Conservation and Recovery Act (RCRA) Metals using EPA Methods 6010/6020 and 7471, and hexavalent chromium (Cr6) using EPA Method 7199. In accordance with the EMP, the NCDEQ, Brownfields was notified within approximately 48 hours of the discovery of each of the USTs. 3.0 LABORATORY ANALYTICAL RESULTS Review of the laboratory analytical results for sample TS-1 indicated concentrations of various VOCs, SVOCs, and RCRA Metals at concentrations below their respective NCDEQ Preliminary Soil Remediation Goals (PSRGs). Laboratory analytical results indicated concentrations of arsenic at 1.5 milligrams per kilogram (mg/kg), which is above the Residential Health Based PSRG; as well as cadmium at 4.5 mg/kg and selenium at 3.5 mg/kg, which are above their respective Protection of Groundwater PSRGs. Review of the laboratory analytical results for sample T-1 indicated concentrations of barium at 31.6 mg/kg, cadmium at 0.10 mg/kg, total chromium at 20.8 mg/kg, lead at 11 mg/kg, and mercury at 0.060 mg/kg. Each of these detections were below respective PSRGs. Laboratory analytical results also indicated concentrations of selenium at 5.2 mg/kg, which is above the Protection of Groundwater PSRG. VOCs and SVOCs were not detected at concentrations above the laboratory detection limits in the T-1 sample. Review of the laboratory analytical results of sample T-2 indicated concentrations of multiple VOCs, SVOCs, RCRA Metals, and Cr6 above the laboratory detection limits. Cr6 was indicated at a concentration above the Residential Health Based PSRG. Multiple VOCs and SVOCs were detected at concentrations above the Protection of Groundwater PSRGs. Naphthalene and lead were detected at concentrations above their respective Protection of Groundwater PSRGs, Residential, and Industrial/Commercial Health Based PSRGs.

Cr6 and ethylbenzene were indicated at concentrations above the Residential Health Based PSRG. Multiple VOCs and SVOCs were detected at concentrations above the Protection of Groundwater PSRGs. Lead was detected at a concentration above the Protection of Groundwater and Residential Health Based PSRG. Naphthalene was detected at a concentration above the Protection of Groundwater PSRGs, and the Residential and Industrial/Commercial Health Based PSRGs. Review of the laboratory analytical results for sample T-4 indicated concentrations of multiple VOCs, SVOCs, and RCRA metals above the laboratory detection limits. Arsenic was detected at a concentration above the Protection to Groundwater and Industrial/Commercial Health Based PSRG. 1-Methylnaphthalene was detected at a concentration above the Protection of Groundwater PSRG. Review of the laboratory analytical results for sample T-5 indicated concentrations of multiple metals above the laboratory detection limits. Arsenic was detected at a concentration above the Residential Health Based PSRG. VOCs, SVOCs, and Cr6 were not detected at concentrations above the laboratory detection limits. The results are summarized in Table 1. Laboratory analytical data sheets are included in Appendix A. 4.0 CLOSING The USTs discovered during the site redevelopment activities for the Seventh Street Properties Brownfields site were removed in accordance with the approved EMP for the site. The areas of remaining impacted soil are covered by either two feet of clean fill or covered by hardscape. This report has been prepared for documentation purposes and ECS recommends it be submitted to the Brownfields Program for their review. According to the Environmental Protection Agency Technical Guide For Addressing Petroleum Vapor Intrusion At Leaking Underground Storage Tank Sites (dated June 2015): • For each building within the lateral inclusion zone, collection additional soil gas, soil, and groundwater samples as necessary to determine the vertical separation distance. Additional investigation is generally unnecessary if the distance to contamination is greater than: o 6 feet for dissolved contamination beneath buildings of any size, or o 15 feet for LNAPL if the overlying building has at least one side shorter than 66 feet in length. Based on the results of the historical sampling activities at the site (notably the previous soil gas sampling results as documented in the Report of Environmental Assessment prepared by ECS dated March 30, 2020), the impacts remaining in the vicinity of T-2 and T-3 are petroleum based, the depths (greater than 6 feet deep) of the samples collected, and the non-residential re-use of the area with slab on-grade construction, the impacts remaining in place do not appear to represent a vapor intrusion concern for the proposed development.

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. 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 of Acrolein 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. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. ANALYTE QUALIFIERS Sample was diluted due to the presence of high levels of non-target analytes or other matrix interference.D3 Analyte concentration exceeded the calibration range. The reported result is estimated.E The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should be considered an estimated value.IK This analyte exceeded secondary source verification criteria low for the initial calibration. The reported results should be considered an estimated value.IL Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1 Matrix spike recovery and/or matrix spike duplicate recovery was below laboratory control limits. Result may be biased low.ML The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A complete list of accreditations/certifications is available upon request.N2 Matrix spike recovery was outside laboratory control limits due to a parent sample concentration notably higher than the spike level.P6 Surrogate recovery not evaluated against control limits due to sample dilution.S4 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.v2 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the associated samples may have low bias.v3 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 02/04/2021 04:45 PM Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 Page 41 of 45 #=CR# QUALITY CONTROL DATA CROSS REFERENCE TABLE Pace Project No.: Project: 92518589 7th & Caswell Tank Pull Lab ID Sample ID QC Batch Method QC Batch Analytical Method Analytical Batch 92518589001 595682 595847T-1 EPA 3050B EPA 6010D 92518589002 595682 595847T-2 EPA 3050B EPA 6010D 92518589003 595682 595847T-3 EPA 3050B EPA 6010D 92518589001 595763 595766T-1 EPA 7471B EPA 7471B 92518589002 595763 595766T-2 EPA 7471B EPA 7471B 92518589003 595763 595766T-3 EPA 7471B EPA 7471B 92518589001 595929 596357T-1 EPA 3546 EPA 8270E 92518589002 595929 596357T-2 EPA 3546 EPA 8270E 92518589003 595929 596357T-3 EPA 3546 EPA 8270E 92518589001 595702 595704T-1 EPA 5035A/5030B EPA 8260D 92518589002 596037 596041T-2 EPA 5035A/5030B EPA 8260D 92518589003 596037 596041T-3 EPA 5035A/5030B EPA 8260D 92518589001 595458T-1 SW-846 92518589002 595458T-2 SW-846 92518589003 595458T-3 SW-846 92518589001 1614567 1614567T-1 SM 2540 G SM 2540G 92518589002 1614567 1614567T-2 SM 2540 G SM 2540G 92518589003 1614567 1614567T-3 SM 2540 G SM 2540G 92518589001 1613765 1613765T-1 3060A EPA 7199 92518589002 1613765 1613765T-2 3060A EPA 7199 92518589003 1613765 1613765T-3 3060A EPA 7199 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 02/04/2021 04:45 PM Pace Analytical Services, LLC 9800 Kincey Ave. Suite 100 Huntersville, NC 28078 (704)875-9092 Page 42 of 45 Page 43 of 45 Page 44 of 45 Page 45 of 45 #=CL# February 09, 2021 LIMS USE: FR - CHRIS ORRELL LIMS OBJECT ID: 92519538 92519538 Project: Pace Project No.: RE: Chris Orrell ECS Southeast, LLP 1900 Center Park Dr Suite D 9809 Aviary Hill Way, Charlott Charlotte, NC 28217 7th & Caswell Tank Pull Dear Chris Orrell: Enclosed are the analytical results for sample(s) received by the laboratory on February 01, 2021.
