Dear Ms. Moutos:
525 N. Tryon St.
Charlotte NC, 28202
Duke Energy is providing the results of the September 2023 semiannual water quality monitoring for the Duke
Energy Progress Asheville CCR Landfill (1119-INDUS), located in Arden, Buncombe County, North Carolina.
Sampling was conducted on September 25-26, 2023, in accordance with the approved Water Quality
Monitoring Plan (WQMP). The September 2023 monitoring event included samples from nine groundwater
monitoring wells, two surface water locations, and one sample of composite leachate. Seep location ASV-DP-
4 and surface water location ASV-LF-SW-1 were not sampled during the September 2023 sampling event
because of dry conditions.
The groundwater analytical results are compared to the groundwater standards found in Title 15A NCAC 02L
.0202 (02L Standards). The surface water analytical results are compared to the surface water standards found
in Title 15A NCAC 02B .0211 (02B Standard) for Class C waters. Leachate analytical results are not compared
to groundwater or surface water quality standards.
Duke Energy personnel sample designated locations for groundwater, surface water, and leachate at the
Asheville CCR Landfill semiannually during March and September. The next water quality monitoring event for
the CCR Landfill is planned for March 2024 with a report of monitoring results to follow.

This semiannual report pertains to the Duke Energy Progress, LLC (Duke Energy) Asheville
Steam Electric Plant (Asheville Plant or Site) Coal Combustion Residual (CCR) Landfill (Landfill;
Permit No. 1119-INDUS-2020) and documents the results of the September 2023 groundwater,
surface water, seep, and leachate monitoring event.
Monitoring results show that groundwater constituents greater than comparison criteria are
attributable to natural variation and not the CCR Landfill, except for sulfate concentrations in
one monitoring well (ASV-LMW-3B). Sulfate concentrations in ASV-LMW-3B are attributed to
the mineral solubilization of gypsum (or another sulfate -bearing mineral) present in the
material used to construct the mechanically stabilized earth (MSE) berm for the CCR Landfill
(SynTerra, 2023a).
1.1 Site and Landfill Information
Duke Energy owns and operates the Asheville Plant, located on approximately 786 acres,
addressed at 46 Duke Energy Lane in Arden, Buncombe County, North Carolina (Figure 1).
The Asheville Plant began operations in 1964 with the construction of two coal-fired electricity -
generating units. Throughout the period of coal-fired generation, CCR was managed and stored
on -Site in the 1964 and 1982 Ash Basins. The Asheville Plant ceased burning coal in January
2020, and the coal-fired units were replaced with a natural gas combined cycle station for
electricity generation; thus, the facility no longer generates CCR. Excavation of the 1982 Ash
Basin was completed in September 2016, and excavation of the 1964 Ash Basin was completed
in June 2022.
Development and construction activities for the on -Site double -lined CCR Landfill began in
February 2020 and were completed in March 2021. The CCR Landfill was constructed in an area
previously developed as a laydown yard, located north of and adjacent to the 1964 Ash Basin
(Figure 1). The CCR Landfill was constructed to support the last phase of ash excavation from
the 1964 Ash Basin. The Landfill received a Permit Approval to Operate from the North Carolina
Department of Environmental Quality (NCDEQ) on April 1, 2021, and the initial placement of
CCR material in the Landfill occurred on the same day. The Landfill Operations Plan (Geosyntec,
2021) and Landfill Permit outline a variety of landfill -approved wastes; however, the primary
waste disposed of in the Landfill is CCR (fly ash and bottom ash). Landfill closure was initiated in
September 2022; closure was completed in April 2023.
1.2 Hydrogeologic Setting
The Asheville Plant is located within the Blue Ridge physiographic province, where soil overlying
the bedrock has formed from the in -place weathering of bedrock. Groundwater at the Site
typically occurs in three interconnected flow zones. The shallowest groundwater flow zone —
the surficial flow zone — occurs in the residual soil and/or the upper section of saprolite.
Beneath the surficial flow zone, the transition zone flow zone occurs in the lower portions of
January 2024 Page 1-1
Project: 00.0069.38.01.02

Semiannual Water Quality Monitoring Report — September 2023 Sampling Event

Arden, North Carolina
the saprolite and partially weathered bedrock and is the most permeable part of the Site
hydrogeologic system. Bedrock underlies the transition zone and comprises the least
permeable flow zone of the Site's hydrogeologic system, where groundwater flow occurs
predominantly along fractures, joints, and faults. Groundwater is usually encountered in the
surficial flow zone; however, as the hydrogeologic units above the bedrock thin to the west and
northwest, groundwater is encountered only within the lower hydrogeologic unit(s).
Groundwater flow direction at the Landfill is generally to the west toward an unnamed stream,
and to the northwest toward a wetland area and several unnamed streams, which converge
into Powell Creek. The wetland area and streams act as groundwater discharge zones
downgradient of the Landfill. Those surface waters are classified as Class C under Title 15A of
the North Carolina Administrative Code (NCAC), Subchapter 02B, Surface Water and Standards
(02B standards). Flow from those surface water features eventually reaches the French Broad
River, located to the west.
1.3 Landfill Semiannual Monitoring Program
The Water Quality Monitoring Plan (WQMP), Revision 2 (Geosyntec, 2019) for the CCR Landfill
was submitted to NCDEQ on October 31, 2019, and approved on February 7, 2020. A WQMP
Revision 3 was submitted in September 2023 (SynTerra, 2023b), and approved on October 12,
2023 (NCDEQ DWM, 2023).
The Landfill semiannual monitoring program, described in detail in the WQMP Revision 3 and
summarized below, consists of:
• Nine groundwater monitoring locations
• Three surface water monitoring locations
• One seep (drainpipe) monitoring location
• One leachate monitoring location
The monitoring locations are shown on Figure 2. A summary of monitoring well construction
information is presented in Table 1, and analytical parameters for the Landfill semiannual
groundwater monitoring program are summarized in Table 2.

2.0 METHODS
2.1 Sampling and Analysis Methods
On September 25 and 26, 2023, Duke Energy personnel (Duke Energy North Carolina Field
Certification #5193) conducted groundwater, surface water, seep, and leachate sampling in
accordance with the North Carolina Solid Waste Management Guidelines. Copies of the field
sampling forms are included in Appendix A. Duke Energy Analytical Laboratory (North Carolina
Laboratory Certification #248) and Pace Analytical Laboratory (North Carolina Laboratory
Certification #40) analyzed the reported parameters and constituents. The laboratory report
and chain -of -custody forms are included in Appendix B.
Duke Energy developed a list of parameters and constituents using guidance from the NCDEQ
Division of Waste Management (DWM), Solid Waste Section (SWS). The samples were analyzed
using the updated parameter and constituent list, approved by NCDEQ on March 20, 2023.
Dissolved selenium was added to the constituent list when the WQMP Update was submitted in
September 2023, and approved by NCDEQ in October 2023. Dissolved selenium will be analyzed
for during subsequent semiannual monitoring events for the CCR Landfill surface water sample
locations. The monitoring parameters along with the U.S. Environmental Protection Agency
(USEPA) Solid Waste (SW)-846 analytical methods, Title 15A, NCAC, Subchapter 02L .0202(g),
Groundwater Quality Standards (02L standards), and 02B standards for Class C waters are
presented in Table 2.
In addition to 02B standards, Duke Energy provides comparisons against in -stream target values
(ISTV) and USEPA National Recommended Water Quality Criteria (NRWQC), with the
qualification that an exceedance of the published value is not necessarily a violation of the
water quality standard for toxicity. As stated by the USEPA, NRWQC standards do not constitute
regulations, nor do they impose a legally binding requirement. Therefore, comparisons with
those criteria are for screening purposes only.
Additional information regarding surface water standards and screening criteria are outlined
below:
• Several 02B standards and ISTV require sampling methods specific to acute or chronic
concentrations and are not applicable to the grab sample method; however acute
standards are considered more applicable to grab sampling and are included for
screening purposes only.
• Hardness -dependent standards require sampling methods specific to acute or chronic
concentrations and are not applicable to the grab sample method. Duke Energy will use
a standard hardness of 25 milligrams per liter (mg/L) for screening purposes only;
however, if the in -stream hardness values for a given sampling event are substantially
less than or greater than 25 mg/L, the minimum in -stream hardness value will be used
to calculate the hardness -dependent standard to more accurately screen analytical
results.

• The 02B surface water standards for chromium are based upon speciation for dissolved
trivalent and hexavalent chromium. Duke energy will sample for total and dissolved
total chromium. Results will be screened to the dissolved trivalent 02B standard; this
standard is also a hardness dependent, acute standard and will be based on 25 mg/L
hardness and used for screening purposes only.
The 02B surface water standard for mercury represents a total concentration and is not
for acute, chronic, or hardness -dependent concentrations. The mercury 02B standard
for Class B, C, and water supply waters is 0.012 micrograms per liter (µg/L). Duke Energy
will use the analytical method USEPA 245.1/SW 7470A for mercury analysis, which has a
reporting limit of 0.050 µg/L and is greater than the 02B criteria of 0.012 µg/L.
2.2 Regulatory Criteria
Evaluation of the semiannual monitoring analytical results is compared to the following
regulatory criteria:
Groundwater
• 02L standards
Surface Water/Seep
• 02B standards
2.3 Statement of Work
The following tasks were completed for semiannual water quality monitoring:
• Collected groundwater, surface water, and leachate samples on September 25 and 26,
2023. (Duke Energy personnel completed this task.)
• Compared groundwater analytical results to 02L standards and historical concentration
ranges.
• Compared surface water analytical results to 02B standards and historical concentration
ranges.
• Developed generalized groundwater contour maps using groundwater elevation data
collected during the September 2023 groundwater monitoring event.
• Calculated groundwater flow velocities based on groundwater elevations at wells
perpendicular to groundwater flow.
• Converted the laboratory -provided electronic data deliverable (EDD) to the format
requirements of the NCDEQ DWM EDD template and submitted copies of the EDDs to
the NCDEQ DWM with this report.
• Prepared and submitted this Semiannual Water Quality Monitoring Report.

Asheville Steam Electric Plant— CCR Landfill (Permit No. 1119-INDUS-2020)
Arden, North Carolina
3.1 Site Groundwater Flow
Groundwater flow in the aquifer beneath the Landfill footprint is generally to the west toward
an unnamed stream, and to the northwest toward a wetland area and several unnamed
streams, which converge into Powell Creek.
Generalized groundwater elevation contours and groundwater flow direction arrows in the
vicinity of the CCR Landfill are shown on Figure 3A for the surficial and transition flow zones
and Figure 313 for the bedrock flow zone. Those contours were developed by calculating
groundwater elevations in each monitoring well using the depth -to -water measurements taken
during the September 2023 monitoring event. In addition, monitoring wells from other
regulatory programs were incorporated into the Landfill monitoring network to be used as
water -level -only wells. Depth -to -water measurements and calculated groundwater elevations
are presented in Table 3. Calculated groundwater flow velocities are presented in Table 4.
Calculated groundwater elevations based on depth -to -water measurements gauged during the
September 2023 monitoring event indicate groundwater at the Landfill generally flows to the
west and northwest, consistent with historical Site observations.
3.2 Historical Range Data
Newly Installed Landfill Groundwater Monitoring Wells
The WQMP Revision 3 included collecting four groundwater samples from each new Landfill
monitoring well prior to the Landfill becoming operational (baseline samples). The four baseline
monitoring events occurred from September 2020 to January 2021, with samples collected
from each well approximately once every 30 days. The baseline monitoring included measuring
groundwater field parameters, gauging depth -to -water in the wells, and analyzing the collected
groundwater samples for the list of parameters and constituents outlined in the WQMP
Revision 3 (same parameter list sampled and analyzed for in the Landfill semiannual monitoring
program). The results of the four baseline sampling events were submitted in the Groundwater
Monitoring Report Baseline Sampling Events #1 Through #4 — CCR Landfill (SynTerra, 2021). For
each newly installed monitoring well, historical ranges of constituent concentrations were
calculated using the analytical results from the four baseline monitoring events.
Existing Wells Incorporated into the Landfill Monitoring Program
Monitoring wells C13-9, C13-9SL, and C13-913R existed at the Site prior to Landfill development but
are incorporated into the Landfill monitoring program. Those three wells were not sampled
during baseline sampling events for the newly installed wells. Rather, data from those wells,
collected as part of other regulatory sampling programs well in advance of Landfill operations,
were used to satisfy the initial baseline sampling requirements. Historical concentration ranges
for existing wells were established using available data collected prior to initiation of Landfill
operations (November 2012 to January 2021).

3.3 Analytical Results
A summary of the groundwater, surface water, and leachate field data is presented in Table 3.
The analytical results and reference comparisons discussed below are summarized in Tables 5
through 8. Sample locations are depicted on Figure 2.
Groundwater Results
Field and analytical results for downgradient and background groundwater samples are
presented in Table S. Groundwater analytical results are compared with 02L standards.
Constituent concentrations equal to or greater than the 02L standard are noted in Table 5 by
bold font. The laboratory analytical reports are included as Appendix B.
A summary of the downgradient groundwater field and analytical results that are equal to or
greater than (or outside the range for pH) applicable comparison criteria are presented in
Table 6.
Groundwater concentrations equal to or greater than (or outside the range for pH) 02L
standards (Table 6) are within historical background ranges and are attributable to natural
variation, except for sulfate in ASV-LMW-3B, which is greater than historical background
concentrations. An alternate source demonstration (ASD) report was completed in accordance
with Rule 40 Code of Federal Regulations (CFR) § 257.94(e)(2). The ASD report concluded that
sulfate concentrations in ASV-LMW-3B are attributed to the mineral solubilization of gypsum
(or another sulfate -bearing mineral) present in the fill material used to construct the MSE berm
for the CCR Landfill (SynTerra, 2023a).
Surface Water/Seep
Field and analytical results for surface water samples are presented in Table 7. The sample
locations are shown on Figure 2. Analytical results for surface water and seep samples, as
available, are compared with applicable 02B Class C surface water standards. Seep location
ASV-DP-4 and surface water location ASV-LF-SW-1 were not sampled during the September
2023 sampling event because of dry conditions. Surface water samples collected during the
September 2023 sampling event were less than applicable 02B Class C surface water standards.
Leachate
A leachate sample (ASV-LCS-1) was collected from the leachate collection discharge pipe on the
west side of the Landfill. Analytical results are presented in Table 8. Leachate analytical results
are not compared to groundwater (02L standards) or surface water (02B standards) quality
standards and are provided for informational purposes only.

3.4 Quality Assurance/Quality Control
Field -performed quality assurance and quality control (QA/QC) consisted of the collection and
analysis of two field blanks (one on each day of sampling) to evaluate whether possible effects
were imparted to the samples by the sample container, preservative, or other exogenous
sources. A field duplicate sample was also collected to estimate sampling and laboratory
precision. The data were validated and deemed usable.
Select samples were diluted, as is normal laboratory practice, to bring samples within the
calibrated range of the analysis. Specifics regarding the samples that were diluted, including the
dilution amount, are reported in the lab report. Additional QA/QC data, laboratory analyses,
and chain -of -custody forms are included in Appendix B.

7) In -stream target value (ISTV) for surface water - In -stream target values established per 15A NCAC 02B .0202 and .0208. An exceedance of a published ISTV is not automatically a violation of the water
quality standard for toxicity.
8) USEPA Criteria for Surface Water - U.S. Environmental Protection Agency National Recommended Water Quality Criteria do not constitute regulations, nor do they impose a legally binding requirement.
Therefore, comparisons with those criteria are for information purposes only.
9) For 15A NCAC 02B Standards and ISTVs with acute and chronic criteria, the acute criteria are considered more applicable to grab sampling; therefore, those values are presented.
Legend:
a - ISTV is based on acute sampling method described in 15A NCAC 02B (11)(e).
b - ISTV for surface water
`- USEPA National Recommended Water Quality Criteria.
d- Comparison criteria based on acute sampling method described in 15A NCAC 02B (11)(e).
Hardness -dependent standard calculated using 25 mg/L hardness and not actual in -stream hardness value. Provided for screening purposes only.
Hardness -dependent standard for chromium III calculated using 25 mg/L hardness and not actual in -stream hardness value. Provided for screening purposes only.

Notes:
1) List of constituents analyzed were approved by NCDEQ on March 20, 2023.
Prepared by: RSB Checked by: TAW
2) Solid Waste Section Identification. Unique identification assigned by the Section.
3) 15A NCAC 02B Standards for Surface Water - 15A NCAC 02B Standards for Class C surface waters. North Carolina surface water and wetland standards (effective September 1, 2022).
4) In -stream target value (ISTV) for surface water - In -stream target values established per 15A NCAC 02B .0202 and .0208. An exceedance of a published ISTV is not automatically a violation of the water quality standard
for toxicity.
5) USEPA Criteria for Surface Water - U.S. Environmental Protection Agency National Recommended Water Quality Criteria do not constitute regulations, nor do they impose a legally binding requirement.
Therefore, comparisons with those criteria are for information purposes only.
6) Dissolved analysis only applicable for samples collected from surface water and/or underdrain outlets as it pertains to receiving water body with water quality standards defined in Title 15A NCAC 02B.
7) Dissolved selenium was added to the constituent list when the Water Monitoring Quality Plan Update was submitted in September 2023, and approved by NCDEQ in October 2023. Dissolved selenium will be analyzed
for during subsequent semiannual monitoring events for the CCR Landfill.
8) For 15A NCAC 02B Standards and ISTVs with acute and chronic criteria, the acute criteria are considered more applicable to grab sampling; therefore, those values are presented.
9) Analytical data presented in this table reflect the Duke Energy Biological Analytical Data Storage System as of 12/06/2023.
10) Bold concentrations are equal to or greater than the 15A NCAC 02B Standards for Class C surface waters (for pH, bold indicates a measurement less than or greater than the indicated range).
11) Samples collected by Duke Energy personnel on September 25, 2023.
12) Surface water sample location LF-SW-1 was not sampled due to dry conditions.
13) J - Value is estimated. The result is below the reporting limit or potentially biased based on data validation.
14) -- no relevant information.
15) <- Concentration not detected at or greater than the adjusted reporting limit.
16) MDL - laboratory method detection limit; MDL values presented are for samples not diluted by the laboratory during analysis.
Legend:
a - ISTV is based on acute sampling method described in 15A NCAC 02B (11)(e).
6 - ISTV for surface water
USEPA National Recommended Water Quality Criteria.
d - Comparison criteria based on acute sampling method described in 15A NCAC 02B (11)(e).
e - Hardness -dependent standard calculated using 25 mg/L hardness and not actual in -stream hardness value. Provided for screening purposes only.
Hardness -dependent standard for chromium III calculated using 25 mg/L hardness and not actual in -stream hardness value. Provided for screening purposes only.
g Selenium standard for lotic water based on a 30-day average.

The questions on this checklist refer to basic review of laboratory analytical reports for completeness and accuracy of data. Any responses requiring follow up action with the analytical lab or field personnel must be
noted in the summary section at the end of this form before the data can be approved for use by technical leads.
Lab Qualifiers:
B2 (Duke) -Target analyte was detected in Method/Prep Blank(s) at a concentration greater than Y2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid
and may be used for compliance purposes.
J (Duke) -Analyte detected above the MDL, but below the RL; analyte concentration should be considered an estimate.
U (Duke) -Analyte was analyzed for, but not detected above the MDL.
Validation Qualifiers:
R- Result is unusable. The sample result is rejected due to serious deficiencies in meeting quality control criteria; the analyte may or may not be present in the sample.
J - Value is estimated. The result is below the reporting limit or potentially biased based on data validation.
U-Analyte was analyzed form but not detected above the minimum detectable concentration (MDC) or method detection limit (MDL).
B -Target analyte detected in the method blank an in the sample at a concentration less than lox the blank concentration.
• Iron (0.00818 mg/L) was detected in the Method Blank (B2); Iron was also detected in FB-20230925-1500 at a concentration less than lox the blank concentration.
• Iron (0.005 mg/L) was detected in the 9/25/2023 Field Blank; Iron was not detected in the associated samples at concentrations less than lox the blank concentration.
• Boron (0.007 mg/L) and Cadmium (0.048 ug/L) were detected in the 9/26/2023 Field Blank; Boron and Cadmium were also detected in the associated samples at concentrations less than lox
the blank concentrations.

QUALIFIERS
Project: J23090047 Asheville CCR LF
Pace Project No.: 92689819
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
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. Contact your Pace PM for the current list of accredited analytes.
TN -The NELAC Institute.

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.
