Dear Ms. Moutos:
525 N. Tryon St.
Charlotte NC, 28202
Duke Energy is providing the results of the September 2024 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 23-24, 2024, in accordance with the approved Water Quality
Monitoring Plan (WQMP). The September 2024 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 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 2025 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 Residuals (CCR) Landfill (Permit
No. 1119-INDUS-2020) and documents the results of the September 2024 groundwater, surface
water, seep, and leachate monitoring event.
Monitoring results show that groundwater constituents greater than comparison criteria are
within background or baseline concentration ranges, except for sulfate concentrations in
monitoring well ASV-LMW-3B. Sulfate concentrations in monitoring well 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, 2024).
1.1 Site and CCR Landfill Information
Duke Energy owns and operates the Asheville Plant, located on approximately 786 acres 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 material 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 former 1964 Ash
Basin (Figure 1). The CCR Landfill was constructed to support the last phase of ash excavation
from the 1964 Ash Basin. The CCR Landfill received a Permit Approval to Operate from the
North Carolina Department of Environmental Quality (NCDEQ) Division of Waste Management
(DWM) on April 1, 2021, and the initial placement of CCR material in the CCR Landfill occurred
on the same day. The Operations Plan, Asheville Steam Electric Plant — CCR Landfill (1119-
INDUS) Rev. 2 (Landfill Operations Plan; Geosyntec, 2021) and Landfill Permit (Permit No. 1119-
INDUS-2020) outline a variety of landfill -approved wastes; however, the primary waste
disposed of in the CCR Landfill is CCR material (fly ash and bottom ash). Closure in place of the
CCR Landfill was initiated in September 2022 and completed in April 2023.

Arden, North Carolina
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 the upper section of saprolite. Beneath
the surficial flow zone, the transition zone flow zone occurs in the lower portions of the
saprolite and partially weathered bedrock and is the most permeable part of the Site
hydrogeologic system. Bedrock underlies the transition zone flow 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 deeper hydrogeologic unit(s).
Groundwater flow direction at the CCR Landfill is generally to the northwest toward several
unnamed streams and a wetland area, which converge into Powell Creek (Figures 3A and 313).
The wetland area and streams act as groundwater discharge zones downgradient of the CCR
Landfill. Those surface waters are classified as Class C under the North Carolina Administrative
Code (NCAC), Title 15A, Subchapter 02B, Surface Water and Standards (02B standards). Flow
from those surface water features eventually reaches the French Broad River to the west.
1.3 CCR Landfill Semiannual Monitoring Program
The Water Quality Monitoring Plan Revision 3 — CCR Landfill (WQMP Revision 3; SynTerra, 2023)
was submitted in September 2023 and approved on October 12, 2023 (NCDEQ DWM, 2023).
The CCR Landfill semiannual monitoring program, described in detail in the WQMP Revision 3
and summarized in Table 1, consists of:
• Nine groundwater monitoring locations
• Four monitoring wells used for water levels only
• Three surface water monitoring locations
• One engineered drain outlet (seep) 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 2, and analytical parameters for the CCR Landfill semiannual
monitoring program are summarized in Table 3A, 3113, and 3C.

Arden, North Carolina
2.0 METHODS
2.1 Sampling and Analysis Methods
On September 23 and 24, 2024, 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
DWM, Solid Waste Section (SWS). The samples were analyzed using the updated parameter and
constituent list, approved by NCDEQ on March 20, 2023. In addition, dissolved selenium was
added to the constituent list when the WQMP — Revision 3 was submitted in September 2023
(SynTerra, 2023) and approved by NCDEQ in October 2023. The monitoring parameters; U.S.
Environmental Protection Agency (USEPA) Solid Waste (SW)-846 analytical methods; NCAC,
Title 15A, Subchapter 02L .0202(g), Groundwater Quality Standards (02L standards); and 02B
standards for Class C waters are presented in Tables 3A through 3C.
In addition to 02B standards, Duke Energy provides comparisons against in -stream target values
(ISTVs) 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 or 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 ISTVs 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 are based on acute and/or chronic sampling methods
and are not applicable to the grab sample method. Duke Energy uses a standard
hardness of 25 milligrams per liter (mg/L) to calculate hardness -dependent standards
for screening purposes. However, if in -stream hardness values are less than 25 mg/L,
actual in -stream hardness values would be used to calculate hardness -dependent
standards for screening purposes because those standards would be more stringent
than screening standards based on 25 mg/L hardness. If constituent concentrations are
greater than hardness -dependent standards based on 25 mg/L hardness but the actual
in -stream hardness values are greater than 25 mg/L, actual in -stream hardness values
would be used to calculate hardness -dependent standards for screening purposes

because those standards would be less stringent than screening standards based on 25
mg/L hardness.
• The 02B surface water standards for chromium are based on speciation for dissolved
trivalent and hexavalent chromium. Duke Energy will sample for total and dissolved
total chromium. Results will be screened against 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

Arden, North Carolina
3.1 Site Groundwater Flow
Groundwater flow in the aquifer beneath the CCR Landfill footprint is generally to the
northwest 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 2024
monitoring event. In addition, monitoring wells from other regulatory programs were incorporated
into the CCR Landfill monitoring network to be used as water -level -only wells. Additional wells used
as water -level -only wells are included in the WQMP.
Depth -to -water measurements and calculated groundwater elevations are presented in Table 4.
Calculated groundwater flow velocities are presented in Table 5. Calculated groundwater elevations
based on depth -to -water measurements gauged during the September 2024 monitoring event
indicate groundwater at the CCR Landfill generally flows to the west and northwest, consistent with
historical Site observations.
3.2 Historical Range Data
Newly Installed CCR Landfill Groundwater Monitoring Wells
The WQMP Revision 3 included collecting four groundwater samples from each new CCR Landfill
monitoring well prior to the CCR 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 CCR 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 CCR Landfill Monitoring Program
Monitoring wells C13-9, C13-9SL, and C13-913R existed at the Site prior to CCR Landfill development
but were incorporated into the CCR Landfill monitoring program (WQMP Revision 3; SynTerra,
2023). 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 before CCR Landfill operations were used to satisfy the initial baseline sampling
requirements. Historical concentration ranges for existing wells were established using

Arden, North Carolina
available data collected prior to initiation of CCR 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 4.
The analytical results and reference comparisons discussed below are summarized in Tables 6
through 9. Sample locations are depicted on Figure 2.
Groundwater Results
Field and analytical results for downgradient and background groundwater samples are
presented in Table 6. Groundwater analytical results are compared with 02L standards.
Constituent concentrations equal to or greater than the 02L standard are noted in Table 6 in
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 7.
Groundwater concentrations equal to or greater than (or outside the range for pH) 02L
standards 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
(Table 7). An alternate source demonstration (ASD) report was completed in accordance with
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, 2024).
Surface Water/Seep
Field and analytical results for surface water samples are presented in Table 8; those sample
locations are shown on Figure 2. Surface water samples are compared to applicable 02B
standards, ISTVs, and USEPA National Recommended Water Quality Criteria (NRWQC) for
Aquatic Life and Human Health. Duke Energy provides comparisons against ISTVs with the
qualification that constituent concentrations greater than the published value are not
necessarily a violation of the water quality standard for toxicity. As stated by the USEPA,
NRWQC standards do not constitute regulations or impose a legally binding requirement.
Therefore, comparisons with those criteria are for information purposes only. An in -stream
hardness of 25 mg/L is assumed for hardness -dependent metal standards and provided for
screening purposes only.
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 2024 sampling event because of

dry conditions. Surface water samples collected during the September 2024 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 CCR Landfill. Analytical results are presented in Table 9. Leachate analytical
results are not compared to groundwater (02L standards) or surface water (0213 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.
As normal laboratory practice, select samples were diluted to bring samples within the
calibrated range of the analysis. Specifics regarding the samples that were diluted, including the
dilution amount, are documented in the lab report. Additional QA/QC data, laboratory
analyses, and chain -of -custody forms are included in Appendix B.

Notes:
List of constituents were approved by NCDEQ on March 20, 2023. In addition, dissolved selenium was included in the September 2023 Water Quality Monitoring Plant (WQMP) update approved by
the NCDEQ in October 2023.
15A NCAC 02B Standards for Class C surface waters. North Carolina surface water and wetland standards (effective September 1, 2022).
ISTV - In -stream target values established per 15A NCAC 02B .0202 and .0208.
USEPA Criteria - U.S. Environmental Protection Agency National Recommended Water Quality Criteria
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.
$ - An exceedance of a published ISTV is not automatically a violation of the water quality standard for toxicity. Comparison value presented is the lesser of the Aquatic Life & Secondary Recreation or Fish
Consumption value, when applicable. ISTV is based on acute sampling method described in 15A NCAC 02B (11)(e). Compliance with acute instream standard is not applicable to sampling
method. An exceedance of a published ISTV is not automatically a violation of the water quality standard for toxicity.
USEPA National Recommended Water Quality Criteria are not a regulation, nor do they impose a legally -binding requirement. Therefore, comparisons with these criteria are for situational context.
Comparison criteria based on acute sampling method described in 15A NCAC 02B (11)(e). Compliance with acute instream standard is not applicable to sampling method and provided
for screening purposes only.
t

° - 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.
s - USEPA Criteria for Surface Water - U.S. Environmental Protection Agency (USEPA) 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.
e - 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.
- - no relevant information.
< - Concentration not detected at or greater than the adjusted reporting limit.
$ - An exceedance of a published ISTV is not automatically a violation of the water quality standard for toxicity. Comparison value presented is the lesser of the Aquatic Life & Secondary Recreation or Fish
Consumption value, when applicable.
# - ISTV is based on acute sampling method described in 15A NCAC 02B (11)(e). Compliance with acute instream standard is not applicable to sampling method. An exceedance of a published ISTV is not
automatically a violation of the water quality standard for toxicity.
USEPA National Recommended Water Quality Criteria are not a regulation, nor do they impose a legally -binding requirement. Therefore, comparisons with these criteria are for situational context.
& - Selenium standard for lotic water based on a 30-dayaverage. Not applicable to the sampling method and provided for screening purposes only.
