Six (6) soil samples were collected and compiled into one composite sample for total metals and SPLP analysis per the Asheville Stockpiled Soil Sampling Plan (Rev. 1) approved on June 20, 2019. The stockpiled soil is estimated to be 10,000 cubic yards (cy) and includes material from the former 1982 Ash Basin dam and excavated soils from a cleared area outside of the Ash Basin waste boundary. Duke Energy proposes to reuse an estimated 6,000 cy of this soil for an off - site project at a Duke Energy facility. The soil will be utilized in the Asheville Fleet Operations Slope Repair Project at 5 East Oakview Road, Asheville, NC. The remaining soil quantities are proposed to be re -used on -site to support construction of the new lined retention basin. This submittal is only being transmitted electronically.

Certified vendor results and QC qualifiers can be found in the vendor lab final report. This report shall not be reproduced, except in full, without the written consent of the Analytical Laboratory. Vendor Data Review Criteria: This vendor data package has been reviewed at the Duke Analytical Laboratory for the following applicable criteria: • Required QC samples collected and analyzed • Required tests performed for all samples • Vendor Laboratory utilized required test methods for all analyses • Vendor Laboratory met all requested Reporting Limits (RL) • QC Results reviewed for outlying recovery values Case Narrative: Method: EPA 6010D Metals SPLP MS and MSD recovery associated with sample Stockpile Comp exceeded QC limits for Aluminum. Batch accepted based on LCS recovery. LCS recovery associate with sample Stockpile Comp was above QC limits for Sodium. Results for this analyte in associated sample may be biased high. Method: EPA 6020 Metals The lab does not hold NELAC/TNI accreditation for Antimony and Silver. Method: EPA 6020E Metals SPLP Antimony was detected in the MB associated with sample Stockpile Comp. Method: 9045D pH The pH test was performed after the method recommended 15 minute holding time. Method: EPA 300.0 Anions SPLP Sulfate was detected in the MB associated with sample Stockpile Comp. Method: EPA 7199 Hexavalent Chromium The precision between the sample (Stockpile Comp) and sample duplicate exceeded laboratory control limits for Hexavalent Chromium. aceAnalytical —pacelabs.com Pace Analytical Services, LLC 9800 KiQcfr&e.

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 B Analyte was detected in the associated method blank. D3 Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference. D6 The precision between the sample and sample duplicate exceeded laboratory control limits. H3 Sample was received or analysis requested beyond the recognized method holding time. L1 Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated samples may be biased high. L5 LCS recovery exceeded QC limits.
