Lead Environmental Specialist Subject: Demolition Area Petroleum Soil Screening Former Coal-Fired Plant Arden, North Carolina NCDEQ UST Incident Number 28421 Dear Chris Gilbert: At your request, Haley & Aldrich1 completed screening of subsurface soil for potential petroleum- impacts at the Duke Energy Progress, LLC (Duke Energy) Former Coal-fired Plant (Former Progress Energy Steam Plant) located at 46 Duke Energy Lane in Arden, North Carolina (site, Figure 1). The following sections describe the background information, soil screening and sampling methods, observations and analytical results, findings and conclusions, and recommendations based on the completed soil screening and associated sampling. Background Information Petroleum-impacted soil, associated with historical underground storage tanks (USTs), was previously identified during coal-fired plant demolition activities at the Duke Energy site (Figure 1). This soil was reported and managed as part of prior North Carolina Department of Environmental Quality (NCDEQ) Underground Storage Tank Program Incident Number 28421 (Incident Number 28421). That incident was associated with two historical, unregulated USTs removed in 2006. Petroleum impacted soil was excavated in November 2022 with confirmation soil sampling conducted by Haley & Aldrich. A threshold of 50 parts per million (ppm) with photoionization detector (PID) screening was used during excavation and the confirmation soil samples results did not contain concentrations above NCDEQ Soil-to-Water Maximum Soil Contaminant Concentrations (MSCCs) with the exception of total petroleum hydrocarbons (TPH) C11-C22 aromatics and dichloromethane, a common laboratory contaminant. 1 For all professional engineering and geology services performed in North Carolina, Haley & Aldrich of North Carolina P.C., License Numbers C-5077 and C-610, respectively, performed the work. Duke Energy Progress, LLC 06 September 2023 Page 2 The former excavation area is shown on Figure 2. An Initial Abatement Action Report summarizing the excavation and sample results was submitted to the NCDEQ. Following review of the report, NCDEQ indicated that Duke Energy could obtain a No Further Action Letter for Incident Number 28421with a Notice of Residual Petroleum (NRP) that would include a land use restriction. Haley & Aldrich is currently assisting Duke Energy with the NRP. Since additional soil excavation and grading is proposed in the demolition area, Duke Energy requested that Haley & Aldrich conduct a supplemental assessment to screen the proposed excavation and grading area for petroleum impacts. We understand that the purpose is to reduce uncertainty of potentially unknown petroleum impacts in soil so that, if present, they can be managed prior to post-demolition excavation and grading. Soil Screening and Sampling Methods From 8 to 10 August 2023, South Atlantic Environmental Drilling and Construction Co., Inc., a subcontractor for Haley & Aldrich, advanced 37 soil borings to facilitate screening of subsurface soil within the proposed excavation area that will be disturbed during site grading activities. The soil borings were advanced on a grid with approximate spacing of 25, 50, or 100 feet as shown on Figure 2. As agreed upon with Duke Energy, soil borings targeted the location of former aboveground storage tanks (ASTs) and USTs, around the perimeter of the 2022 petroleum-impacted soil excavation area, the former administrative building area to the west, and the proposed storm sewer along the western side of the former coal-fired plant demolition area. The area to the north and east were excluded since that area was previously disturbed to approximately 10+ feet during demolition activities. The area to the south was excluded since it was primarily occupied by a coal pile prior to demolition and is not currently anticipated to be disturbed to a depth of more than 1 or 2 feet during demolition and grading activities. Additionally, towards the west, borings were not advanced in the vicinity of prior borings completed by Anchor QEA of North Carolina, PPLC (as reported in the Initial Site Assessment Report and Incident Closure Request for Incident #89246 dated July 2018), since samples collected during the 2018 assessment reportedly contained no detectable concentrations of TPH in the soil and no detectable concentrations of petroleum constituents in the groundwater above the North Carolina Administrative Code, Title 15A, Subchapter 2L Groundwater Quality Standards. Soil borings were advanced using a track-mounted drill rig and direct push technology methods. Borings near the former maintenance building, former ASTs and USTs, and limit of excavated impacted soil were advanced to approximately 16 feet below ground surface (ft bgs). Borings located along the proposed storm sewer line were advanced to approximately 10 ft bgs. Borings located in the west-central portion of the project area (i.e., the former administrative building area where post-demolition grading soil disturbance is expected to be shallow), were advanced to approximately 4 ft bgs. Boring locations SB-07 and SB-08 were added to the sampling program to collect additional data around boring SB-04. At each sampling location, Haley & Aldrich staff logged the soil type and screened the soil on a 2-ft interval with a PID. Results were recorded on boring logs, which are included in Appendix A. If PID results exceeded 50 ppm, the threshold previously used for petroleum-impacted soil excavation at the site, the sample was analyzed in the field for TPH diesel range organics (DRO) using a SiteLab® portable Duke Energy Progress, LLC 06 September 2023 Page 3 field analyzer (UVF-Trilogy analyzer, model no. 7200-004-EDRO), which uses Ultraviolet Fluorescence (UVF) technology to detect hydrocarbons in the C10 to C36 diesel and oil-carbon range. Fifteen samples (plus one duplicate) were field analyzed for TPH DRO from varying depths at nine boring locations. Based on a TPH DRO result with the SiteLab® UVF analyzer greater than 100 ppm (the NCDEQ Action Level for TPH DRO), Haley & Aldrich submitted four samples for laboratory analysis. The samples were collected from soil borings SB-04, SB-13, SB-18, and SB-20 at depths between 2 and 16 ft bgs. The samples were submitted to Pace Analytical Services, LLC for the following analyses consistent with those specified in Table 3: Approved Soil Analyses Methods for Petroleum UST Closures, Over-Excavation and Site Checks Section 4. “Used/Waste Oil (non-hazardous)” of NCDEQ’s Comprehensive Tables for Corrective Action Guidelines, UST Section, Version 7 September 2022.  volatile organic compounds by U.S. Environmental Protection Agency (EPA) Method 8260;  semivolatile organic compounds by EPA Method 8270;  Massachusetts Department of Environmental Protection (MADEP) volatile petroleum hydrocarbons (VPH);  MADEP extractable petroleum hydrocarbons (EPH);  total metals (chromium, hexavalent chromium, and lead);  pesticides by EPA Method 8081 (submitted on hold); and  polychlorinated biphenyls by EPA Method 8082. Because previous sampling results from the area of the former USTs did not detect pesticides, pesticide samples collected during this sampling event were placed on hold and were not analyzed. Observation and Analytical Results On-site soil is described as brown silty sand with gravel followed by dark brown or red-brown sandy silt or sandy clay. Based on observed soil saturation, groundwater was encountered between 11 and 15 ft bgs. Refusal above the target boring depth was encountered at one location: boring SB-01 at a depth of 14.6 ft bgs. The results of PID screening from each 2-foot interval is listed on the boring logs included in Appendix A. The maximum PID reading for each of the 37 boring locations is summarized on Table I. The readings ranged from less than the detection limit (<0.1 ppm) to 563.4 ppm. A PID reading greater than 50 ppm was recorded at 15 sampling intervals from nine soil borings (SB-04, SB-07, SB-08, SB-12, SB-13, SB-16, SB-17, SB-18, and SB-20) at depths ranging between 2 feet and 16 feet bgs. The 15 sampling intervals with a greater than 50 ppm reading were then field-analyzed for TPH DRO. The 15 sampling results (plus one duplicate from boring SB-04) are shown on Table II. The following eight samples exhibited a TPH DRO result greater than the NCDEQ Action Level of 100 ppm: Duke Energy Progress, LLC 06 September 2023 Page 4  SB-04 at 12 to 14 ft bgs  SB-07 at 14 to 16 ft bgs  SB-08 at 14 to 16 ft bgs  SB-12 at 8 to 10 ft bgs  SB-13 at 8 to 10 ft bgs  SB-18 at 14 to 16 ft bgs  SB-20 at 2 to 4 ft bgs The sample locations, which are highlighted on Figure 2, are in the vicinity of prior petroleum impacts managed under Incident Number 28421. The TPH DRO concentrations for the samples analyzed with the SiteLab® UVF analyzer ranged from 107 ppm (SB-18) to 3,136 ppm (SB-04). Four of the samples from borings SB-04, SB-13, SB-18, and SB-20 were also submitted for laboratory analysis. Borings SB-07 and SB-08 were offset from the primary boring SB-04. Since the TPH DRO results were lower in the samples from the offset borings than the primary boring, the samples from borings SB-07 and SB-08 were not submitted for laboratory analysis. Results from boring SB-04 sample will be used to characterize the area. The sample from boring SB-12 was not submitted to the laboratory since it was collected from a gravel layer with an insufficient volume of soil for laboratory analysis. Laboratory analytical results from the four soil samples are presented in Table III and the laboratory analytical report is included in Appendix B. Laboratory results were compared to the NCDEQ UST Section Soil-to-Water, Residential, and Industrial/Commercial MSCCs. Results are summarized as follows.  No analytes were detected at concentrations greater than the Industrial/Commercial MSCCs.  Multiple analytes (two MADEP EPH/VPH carbon ranges, 1-methylnaphthalene, and naphthalene) were detected from boring SB-04 from 12 to 14 ft bgs at concentrations greater than the Soil-to-Water and Residential MSCC but less than the Industrial/Commercial MSCC.  Several analytes were detected above the Soil-to-Water MSCCs but below the Residential MSCCs in the remaining samples, including EPH/VPH C9-C22 aromatics, benzene in boring SB-13 (8 to 10 ft), p-isopropyltoluene in borings SB-18 (14 to 16 ft) and SB-20 (2 to 4 ft), and naphthalene and tetrachloroethene in boring SB-18 (14 to 16 ft). Findings and Conclusions Haley & Aldrich screened subsurface soil from 37 boring locations. The boring locations targeted areas of former USTs/ASTs and areas previously developed with buildings and proposed to be disturbed during post-demolition grading activities. Fifteen soil samples from different depth intervals at nine boring locations were identified to have a PID reading greater than 50 ppm. Those samples were then analyzed for TPH DRO in the field using a SiteLab® UVF analyzer, which indicated that seven of the samples (one depth interval from seven boring locations) had TPH DRO concentrations exceeding the NCDEQ Action Level of 100 ppm. Four of the samples were submitted for laboratory analysis. Results Duke Energy Progress, LLC 06 September 2023 Page 5 indicated concentrations greater than the Soil-to-Groundwater MSCCs and Residential MSCCs, but no analytes were detected at concentrations greater than the Industrial/Commercial MSCCs. The results of this assessment indicated TPH impacted soils are present in the area of the former USTs and 2022 petroleum-impacted soil excavation; therefore, the TPH impacts identified during this assessment are likely associated with those previously identified petroleum impacts managed under Incident Number 28421 and do not constitute a new release. An NRP is being prepared and will be recorded for Incident Number 28421. The NRP will include land use restrictions limiting the use of the property to industrial/commercial use and prohibit the use of groundwater for water supply. Duke Energy is preparing the plat specifying that the NRP restrictions will apply to the approximate 18-acre demolition area, including the area of proposed excavation and grading assessed during this investigation. Recommendations Haley & Aldrich recommends that soil that has concentrations of hydrocarbons above Soil-to- Groundwater MSCCs (or Residential MSCCs where they are lower) that is excavated as part of grading activities or other future soil excavations be managed as a waste and be properly disposed of off-site at a permitted facility in accordance with Appendix E of the NCDEQ UST Section Comprehensive Appendices for Corrective Action Guidelines.

Results in bold are detected. 2. ND (#): Not detected above the indicated method detection limit (MDL). 3. Lab qualifiers defined as follows: B: Analyte was detected in the associated method blank. IK: The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should be considered an estimated value. J: Analyte detected below the reporting limit, therefore result is an estimate. M1: Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery. N2: 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. R1: RPD value was outside control limits. v1: The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the associated samples may have a high bias. v2: 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. 4. Detected concentrations and MDLs were compared to NCDEQ Maximum Soil Contaminant Concentrations (MSCCs). Values that are above the MSCC are flagged in [ ] and shaded as follows. [A]: Result or MDL is greater than Soil-to-Water Maximum Contaminant Concentration [B]: Result or MDL is greater than Residential Soil Cleanup Levels [C]: Result or MDL is greater than Industrial/Commercial Soil Cleanup Levels 5. Chromium III MSCCs were used because the chromium IV results are below laboratory reporting limits. 6.

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. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.
