Dear Mr. Mussler:
In general accordance with the CCR Surface Impoundments Closure Guidelines for Protection of
Groundwater provided by the Division of Water Resources on November 4, 2016, Duke Energy
Carolinas, LLC (DEC) has completed the removal of CCR at the Dan River Steam Station. On July
31, 2019, Duke Energy provided the CCR Visual Removal Verification Report, which included
visual observation of CCR removal and the PLM sampling results.
The attached technical memorandum provides the results of the ash basin closure soil sampling
that was completed concurrently with the visual observations and PLM sampling. If you have
any questions or need any clarification regarding the information provided, please contact me
at [e-mail] or [phone].

Subject: Closure Soil Sampling Summary
Dan River Steam Station — Eden, NC
SynTerra performed soil sampling at the Duke Energy Dan River Steam Station (Dan River, the
Site) during 2019. Sampling was conducted in areas of formerly deposited ash to characterize
Site conditions after ash was removed from the former ash basins. The sample collection was
conducted in accordance with the "Excavation Soil Sampling Plan, Dan River Steam Station Ash
Basin System," Rev. 2, dated December 2018, developed by Duke Energy and submitted to and
approved by the North Carolina Department of Environmental Quality (NCDEQ).
The project entailed conducting soil boring operations by direct -push technology (DPT)
methods and equipment to obtain soil samples on a one -acre grid within the ash basins. Soil
samples were collected at 52 locations across the Site. Within each one -acre grid, soil samples
were collected at five (5) depth intervals to a maximum depth of 17.0-17.5 feet below ground
surface (bgs), unless the water table or rock was encountered.
NC licensed well drillers performed the soil boring operations and properly abandoned the
borings upon completion. SynTerra personnel provided soil boring operations oversight,
including coordinating field activities with Dan River personnel, selecting boring locations,
logging soil sample descriptions, and performing soil sampling. Soil samples were analyzed for
total inorganics and synthetic precipitation leaching procedure (SPLP) analyses.
This memorandum provides a summary of soil sample analytical results.
CLOSURE SOIL SAMPLING AND ANALYSIS
Due to the sequential process of final ash excavation and dewatering, the Dan River closure soil
sampling occurred during four mobilization events:
• April 17-18, 2019
• May 14-15, 2019
• May 22-23, 2019
• June 20, 2019

Ash Basin Closure Soil Sampling Summary August 15, 2019
Dan River Steam Station Page 2 of 2
A total of 280 basin closure ("BC-" or "NC-") soil sample locations were designated as part of
the Site half -acre grid system for visual ash verification, polarized light microscopy (PLM)
sampling, and analytical analysis in accordance with the sampling plan. Analytical sampling
was performed at fifty two (52) locations. Samples were not collected at eight (87) locations
where ash was never historically deposited, as shown on Figure 1.
Soil samples were collected from a total of 52 'BC-" or "NC-" locations, meeting the sampling
plan protocol to collect one soil sample for each acre of excavated ash basin at the Site
(approximately 53 acres). Figure 1 shows the half -acre grid system and soil sample locations for
each acre.
At locations where borings were drilled, soil samples were collected from the following five (5)
intervals for laboratory analyses, unless the water table or rock was encountered:
0 0 to 0.5 feet bgs,
• 2 to 2.5 feet bgs,
• 7 to 7.5 feet bgs,
• 12 to 12.5 feet bgs, and
• 17 to 17.5 feet bgs.
Soil samples were submitted to the Duke Energy Analytical Laboratory for total inorganics and
SPLP analyses. Table 1 and Table 2 provide the basin closure soil sample analytical results.
Notes for Table 1 and Table 2 are provided in Table 3.
Evaluation of analytical data is not provided in this technical memorandum. It is anticipated
that evaluation of the soil sampling data will be included in the forthcoming Corrective Action
Plan (CAP) Update or assessment update for the Site.

< - concentration not detected at or above the adjusted reporting limit.
^ Federal MCL.
* - Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April 1, 2013.
1g - Result confirmed by second analysis performed out of hold.
2g - The concentration in the Blank QC is less than the reporting limit but greater than 1/2 the reporting limit.
B - Target analyte detected in method blank at or above the reporting limit. Target analyte concentration in sample is less than 1OX the
concentration in the method blank. Analyte concentration in sample could be due to blank contamination.
B1 - Target analyte detected in method blank at or above the reporting limit. Target analyte concentration in sample was greater than
1OX the concentration in the method blank. Analyte concentration in sample is not affected by blank contamination.
B2 - Target analyte was detected in blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit.
Analyte concentration in sample is valid and may be used for compliance purposes.
B3 - Target analyte was detected in Continuing Calibration Blank(s) at a concentration greater than 1/2 the reporting limit but less than
the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.

LABORATORY FLAGS (CONTINUED)
B5 - Target analyte was present in blank(s) above the method detection limit but less than the reporting limit. Data is valid for
compliance purposes.
B6 - Target analyte was detected in Continuing Calibration Blank(s) at a concentration greater than the reporting limit.
BC - The same analyte was detected in an associated blank at a concentration above 1/2 the reporting limit but below the
laboratory reporting limit.
CO - Result confirmed by second analysis.
CH - The continuing calibration for this compound is outside of Pace Analytical acceptance limits. The results may be biased high.
CL - The continuing calibration for this compound is outside of Pace Analytical acceptance limits. The results may be biased low.
CR - The dissolved metal result was greater than the total metal result for this element. Results were confirmed by reanalysis.
CU - The continuing calibration for this compound is outside of Pace Analytical acceptance limits. Analyte presence below reporting limits
in associated samples. Results unaffected by high bias.
D3 - Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
D4 - Sample was diluted due to the presence of high levels of target analytes.
D6 - The precision between the sample and sample duplicate exceeded laboratory control limits.
E - Analyte concentration exceeded the calibration range. The reported result is estimated.
H - Sample analyzed past the recommended holding time.
H1 - Analysis conducted outside the EPA method holding time.
H2 - Extraction of preparation conducted outside EPA method holding time.
H3 - Sample was received or analysis requested beyond the recognized method holding time.
H6 - Analysis initiated outside of the 15 minute EPA required holding time.
HS - Results are from sample aliquot taken from VOA vial with headspace (air bubble greater than 6 mm diameter).
j - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
j- - Estimated concentration, biased low.
j+ - Estimated concentration, biased high.
Ll - Analyte recovery in the laboratory control sample (LCS) was above quality control (QC) limits. Results may be biased high.
L2 - Analyte recovery in the laboratory control sample (LCS) was below QC limits. Results for this analyte in associated samples may be
biased low.
L3 - Analyte recovery in the laboratory control sample (LCS) exceeded quality control (QC) limits. Analyte presence below reporting
limits in associated samples. Results unaffected by high bias.
M - Matrix spike / matrix spike dup failure.
M1 - Matrix spike recovery was high: the associated Laboratory Control Spike (LCS) was acceptable.
M2 - Matrix spike recovery was Low: the associated Laboratory Control Spike (LCS) was acceptable.
M4 - The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level.
M6 - Matrix spike and Matrix spike duplicate recovery not evaluated against control limits due to sample dilution.
N2 - The lab does not hold accreditation for this parameter.
P2 - Re -extraction or re -analysis could not be performed due to insufficient sample amount.
P4 - Sample field preservation does not meet EPA or method recommendations for this analysis.
