This semiannual report pertains to the Duke Energy Carolinas, LLC (Duke Energy) Marshall
Steam Station (Marshall, Site) Flue Gas Desulfurization (FGD) Residue Landfill (Landfill) and
documents the results of the March 2023 FGD Landfill groundwater, surface water, and
leachate monitoring event.
1.1 Site and Landfill Information
Duke Energy owns and operates Marshall Steam Station, located at 8320 NC Highway 150E in
Terrell, Catawba County, North Carolina (Figure 1).
The North Carolina Department of Environmental Quality (NCDEQ) Division of Waste
Management (DWM) issued a permit to operate (PTO) the FGD Residue Landfill (Landfill; No.
1809 - INDUS) on November 21, 2006. Closure activities began in July 2018 and were completed
in March 2019; the Closure Permit was issued on June 30, 2020. The Landfill encompasses an
18-acre landfill footprint. The FGD Residue Landfill is constructed with a leachate collection and
removal system and an engineered liner system to prevent effects on groundwater.
1.2 Hydrogeologic Setting
The Landfill site is located within the Piedmont physiographic province (Piedmont). Piedmont
bedrock primarily consists of igneous and metamorphic bedrock. The fractured bedrock is
overlain by a mantle of unconsolidated material known as regolith. The regolith includes, where
present, the soil zone, a zone of weathered, decomposed bedrock known as saprolite, and
alluvium. Saprolite, the product of chemical and mechanical weathering of the underlying
bedrock, is typically composed of clay and coarser granular material up to boulder size and may
reflect the texture of the rock from which it was formed. The weathering product of granitic
rocks may be quartz -rich and sandy -textured, whereas rocks poor in quartz and rich in feldspar
and other soluble minerals form a more clayey saprolite.
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 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 hydrogeologic system, where groundwater flow occurs
predominantly along fractures, joints, and faults. Groundwater is usually first encountered in
the surficial flow zone.
Groundwater flows to the south and emerges in a discharge zone. The water flows from the
discharge zone to an unnamed tributary that ultimately flows to Lake Norman. The surface
water classification of Lake Norman is WS-IV.

1.3 Landfill Semiannual Monitoring Program
The initial Water Quality Monitoring Plan (WQMP) (Altamont, 2006) has been revised over time
to incorporate changes. The March 2023 sampling event and this Semiannual Water Quality
Monitoring Report comply with WQMP, Revision 2 (Wood, 2019) submitted to the DWM on
July 24, 2019. The Landfill semiannual monitoring program, described in detail in the WQMP,
consists of nine groundwater monitoring locations, one surface water monitoring location, and
one leachate monitoring location (Table 3 and Figure 2). A summary of monitoring well
construction information is presented in Table 1, and analytical parameter coverage for the
Landfill semiannual water quality monitoring program is summarized in Table 2.

2.0 METHODS
2.1 Sampling and Analysis Methods
Groundwater sampling was performed by Duke Energy Groundwater Science Group personnel
(Duke Energy North Carolina Field Certification #5193) on March 27, 2023, 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) analyzed the samples for 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. The
monitoring parameters, along with the U.S. Environmental Protection Agency (USEPA) Solid
Waste (SW)-846 analytical methods, Title 15A, North Carolina Administrative Code (NCAC),
Subchapter 02L .0202(g) Groundwater Quality Standards (02L), and Title 15A, NCAC, Subchapter
02B .0200, Surface Water and Wetland Standards (02B) are presented in Table 2.
2.2 Regulatory Criteria
Semiannual monitoring analytical results were compared to the following regulatory criteria:
Grnundwater
• 02L standard
Surface Water
• 02B standard
2.3 Statement of Work
The following tasks were completed for semiannual water quality monitoring:
• Collected groundwater, surface water, and leachate samples on March 27, 2023.
• Reviewed the laboratory analytical results pertaining to the parameters listed in Table 2.
• Compared groundwater analytical results to the 02L standard and historical
concentration ranges.
• Compared surface water analytical results to the 02B standard and historical
concentration ranges.
• Developed generalized groundwater surface contour maps using groundwater elevation
data. 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.

Terrell, North Carolina
WIM.7*1111%V
3.1 Site Groundwater Flow
Groundwater flow in the aquifer beneath the Landfill footprint generally flows to the east and
southeast beneath the landfill, toward the Ash Basin and Lake Norman.
Generalized groundwater elevation contours and groundwater flow direction arrows in the
vicinity of the Landfill are shown on Figure 3 for the shallow flow zone. These contours were
developed by calculating groundwater elevations in each monitoring well using the depth -to -
water measurements taken during the March 2023 monitoring event. Depth -to -water
measurements and calculated groundwater elevations are presented in Table 1. Calculated
groundwater flow velocities are presented in Table 4. Calculated groundwater elevations based
on depth -to -water measurements gauged during the Spring 2023 water level sweep (March 27,
2023) indicate groundwater at the Landfill generally flows to the east-southeast, consistent
with historical Site observations.
3.2 Analytical Results
Analytical results and reference comparisons discussed below are summarized in Table 5
through Table 9. Sample locations are depicted on Figure 2.
Leachate
A leachate sample was collected from C-1 on the east side of the Landfill. Analytical results are
presented in Table 5. Leachate analytical results are not compared to groundwater (02L) or
surface water (02B) quality standards and are provided for informational purposes only.
Groundwater Results
Field and analytical results for the collected 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 their 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
applicable comparison criteria are presented in Table 7. Constituent concentrations greater
than their applicable comparative criteria are within the historical range. The concentrations
and historical range are demonstrated in Appendix C.
Surface Water
Field and analytical results for the surface water sample are presented in Table 8. The sample
location, SW-1, is depicted shown on Figure 2. Analytical results for the surface water sample
are compared with applicable 02B Class WS-IV surface water standards. No constituent
concentrations were greater than 02B Class WS-IV surface water standards.

Marshall Steam Station — FGD Residue Landfill (Permit No. 1809-INDUS)
Terrell, North Carolina
Duke Energy provides comparisons against in -stream target values 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, National Recommended Water Quality Criteria (NRWQC)
do not constitute regulations, nor do they impose a legally binding requirement. Therefore,
comparisons with those criteria are for information purposes only.
Iron and manganese concentrations were reported greater than USEPA NRWQC. NCDEQ has
not adopted the iron and manganese NRWQC as surface water standards because those
constituents occur naturally at relatively high concentrations in the Piedmont region.
3.3 Quality Assurance/Quality Control
Field -performed quality assurance and quality control (QA/QC) consisted of the collection and
analysis of a field blank to evaluate if contamination was 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.
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 in the lab report in Appendix B. Additional QA/QC data, laboratory
analyses, and chain -of -custody forms are included in Appendix B.

15A NCAC 02B Standards for Surface Water - 15A NCAC 02B Standards for Class WS-IV surface waters. North Carolina surface water and wetland standards (effective September 1, 2022).
ISTV for Surface Water - In -stream target values established per 15A NCAC 02B .0202 and .0208.
USEPA Criteria for Surface Water - 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.
Dissolved constituents are applicable to surface water analytical parameters only.
$ - 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.
"- 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
t - Hardness -dependent standard calculated using 25 mg/L hardness and not actual in -stream hardness value. Provided for screening purposes only.

Notes:
Analytical data presented in this table reflect the Duke Energy Biological Analytical Data Storage System as of 05/04/2023.
Bold concentrations are equal to or greater than the 02B for surface waters (for pH, bold indicates a measurement less than or greater than the indicated range).
Z -15A NCAC 02B Standards for Class WS-IV surface waters. North Carolina surface water and wetland standards (effective September 1, 2022). Other comparison criteria are listed as
applicable when no 02B standards exist.
Samples collected by Duke Energy personnel on March 20, 2023
1- Solid Waste Section Identification. Unique identification assigned by the Section.
$ - 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. (Only acute values were considered).
- 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 - Hardness -dependent standard calculated using 25 mg/L hardness and not actual in -stream hardness value. Provided for screening purposes only.
&- Selenium standard for lotic water based on a 30-dayaverage. Not applicable to the sampling method and provided for screening purposes only.
no relevant information.
< - Concentration not detected at or greater than the adjusted reporting limit.
J - Value is estimated. The result is below the reporting limit or potentially biased based on data validation.

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:
J-Analyte detected above the MDL, but below the RL; analyte concentration should be considered an estimate.
7
M - MS and/or MSD recovery was outside of the control limits; the associated LCS recovery was acceptable.
U-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 10x the blank concentration.
• Mercury MS/MSD % recoveries low for C-1 LEACHATE (M).
• The RPD between MS-14 and the field duplicate is greater than 35%for Iron (0.011/0.017 mg/L).
• Nitrate (0.04 mg/L), Nitrate as N (0.01 mg-N/L), Calcium (0.013 mg/L), and Molybdenum (0.654 ug/L) were detected in the Equipment Blank; Nitrate, Nitrate as N, and Molybdenum were also
detected in the samples at concentrations less than 10x the blank concentrations.
• Nitrate (0.04 mg/L), Nitrate as N (0.01 mg-N/L), and Chromium (0.192 ug/L) were detected in the Field Blank; Nitrate, Nitrate as N, and Chromium were also detected in the samples at
concentrations less than lox the blank concentrations.
