Box 32861 Charlotte, NC 28232-2861 Bennett.Thompson@atriumhealth.org Steven.Garrett@atriumhealth.org Subject: 801 Baxter Fill Export Approval Domestic Laundry Brownfields Project Charlotte, Mecklenburg County Brownfields Project Number 25032-21-060 Dear Mr. Thompson and Mr. Garrett, The North Carolina Department of Environmental Quality (DEQ) Brownfields Program received a request to export approximately 560 cubic yards of fill soil/material from the former Domestic Laundry Brownfields Property. This email request was submitted on your behalf by Ms. Amy Kenwell with Geosyntec Consultants of NC, P.C., on November 8, 2022, and requests approval to export the fill to Republic Services’ Charlotte Motor Speedway Landfill in Concord, North Carolina. For this request, DEQ Brownfields reviewed the November 8, 2022 email and the analytical report. Based on our review of the data, the DEQ Brownfield determines that the fill may be exported to Republic Services’ Charlotte Motor Speedway Landfill in Concord, North Carolina. If another export facility is selected, please contact us and we will assist you in determining if additional sampling is needed for the receiving facility. In accordance with the approved Environmental Management Plan (EMP), soils are to be field screened during excavation prior to export from the property. If unanticipated impacts are identified during excavation, please refer to the EMP for further actions and cease transfer until appropriate characterization can be completed. In accordance with the site’s approved EMP, an annual Redevelopment Summary Report will be submitted to DEQ Brownfields. Details related to the disposition of the fill including but not limited to, total volume, general description of field screening efforts, etc. should be included with the Redevelopment Summary Report. Mr. Thompson and Mr. Garrett November 9, 2022 Page 2 Please be advised that this approval does not waive any applicable requirement to obtain any necessary permits, licenses or certifications which may be required from other state or local entities. If you have questions about this correspondence or require additional information, please feel free to contact me by phone at 984-275-5391 or by email at peter.doorn@ncdenr.gov. Sincerely, Peter L.

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 0.9º C. GC/MS VOA Method 8260D: The leachate blank for preparation batch 400-598006 and analytical batch 400-598350 contained 2-Butanone (MEK) above the method detection limit. This target analyte concentration was less than the reporting limit (RL); therefore, re-extraction and/or re-analysis of samples was not performed. Method 8260D: Due to the TCLP extraction process, the following samples were diluted X5: Fill-20221020 (Grab) (680-223795-1) and Fill-20221020 (Composite) (680-223795-2). 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 RPD of the laboratory control sample (LCS) and laboratory control sample duplicate (LCSD) for preparation batch 400-598664 and analytical batch 400-598902 recovered outside control limits for the following analytes: Pyridine. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. Metals Method 7470A: The method blank for preparation batch 400-598005 and 400-598538 and analytical batch 400-598841 contained Mercury above the method detection limit. This target analyte concentration was less than the reporting limit (RL); therefore, re-extraction and/or re-analysis of samples was not performed. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. General Chemistry Method 7196A: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 400-599462 and analytical batch 400-599470 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. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
