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 2024 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.

Terrell, North Carolina
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 2024 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 1 and Figure 2). A summary of monitoring well
construction information is presented in Table 2 and analytical parameter coverage for the
landfill semiannual groundwater monitoring program is summarized in Table 3A; likewise,
Table 3B shows analytical parameters for the surface water monitoring program. Table 3C
shows leachate analytical parameters.
The analytical parameters included in Tables 3A, 313, and 3C (except for dissolved selenium)
align with Duke Energy's Solid Waste Constituents and Analytical Methods (FID 1777041)
request letter to DWM dated March 15, 2023. That letter was approved by the DWM in a
March 20, 2023, letter (FID 1777045) to Duke Energy. A WQMP template for Duke Energy
landfills (FID 1809728) was subsequently submitted to the DWM on May 26, 2023. The WQMP
template included dissolved selenium analysis for surface water samples, and was initially
approved in a July 3, 2023, letter (FID 1809722) from DWM to Duke Energy.

2.0 METHODS
2.1 Sampling and Analysis Methods
Groundwater, surface water, and leachate sampling was performed by Duke Energy
Groundwater Science Group personnel (Duke Energy North Carolina Field Certification #5193)
on March 25, 2024, 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 (0213) are presented in Table 3A and 3B.
2.2 Regulatory Criteria
Semiannual monitoring analytical results were compared to the following regulatory criteria:
Groundwater
• 15A NCAC 02L .0202(g) Groundwater Quality standards (02L)
Surface Water

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 2024 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 2024 water level sweep (March 25,
2024) indicate groundwater at the Landfill generally flows to the east-southeast, consistent
with historical Site observations.
3.2 Analytical Results
A summary of the groundwater, surface water, and leachate field data are presented in Table 5.
Analytical results and reference comparisons discussed below are summarized in Table 6
through Table 10. Sample locations are depicted on Figure 2.
Groundwater
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 is presented in Table 7. Constituent concentrations greater than
their applicable comparative criteria are within the historical range.
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 C and WS-IV surface water standards. Constituent
concentrations greater than 02B s are noted in Table 8 by bold font.
The surface water analytical results equal to or greater than applicable comparison criteria are
presented in Table 9. The constituent concentration greater than applicable comparative
criteria is within the historical range.

Leachate
A leachate sample was collected from C-1 on the east side of the Landfill. Analytical results are
presented in Table 10. Leachate analytical results are not compared to groundwater (02L) or
surface water (02B) quality standards and are provided for informational purposes only.
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.

Notes:
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 - 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
Hardness -dependent standard calculated using 25 mg/L hardness and not actual in -stream hardness value. Provided for screening purposes only.
x - Hardness -dependent standard for chromium III 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.
