Duke Energy is providing the result of the semiannual water quality monitoring for the Duke Energy
Carolinas, Marshall Steam Station, Flue Gas Desulfurization (FGD) Landfill, located near Terrell,
North Carolina.
On September 28, 2022, leachate and groundwater samples were collected in accordance with the
facility's Water Quality Monitoring Plan (WQMP) approved July 24, 2019. No surface water sample
was collected from SW-1 during the September 2022 sampling event because of dry conditions.
Field sampling forms, chain of custody (COC) forms, and laboratory reports are included in Appendix
A and B.
The leachate sampling field and analytical results are presented in Table 5. Leachate analytical
results are not compared to groundwater or surface water quality standards and are provided for
informational purposes only.
A summary of the groundwater sampling field and analytical results are presented in Table 6. The
analytical results for the constituents are compared to the groundwater standards found in Title 15A
NCAC 02L .0202 (21- Standards). Results with values that are equal to or greater than the 2L
Standards are indicated on Table 6 by bold font. A summary of the analytical results that are equal
to or greater than the 2L Standards and a preliminary analysis of the cause and significance of such
occurrences are presented in Table 7.
Leachate, groundwater, and surface water locations at the Marshall FGD Landfill are sampled
semiannually during March and September. The next water quality monitoring event is planned for
March 2023 with a report of monitoring results to follow.

Semiannual Water Quality Monitoring Report — September 2022 Sampling Event
Marshall Steam Station — FGD Residue Landfill (Permit No. 1809-INDUS)
Terrell, North Carolina
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 September 2022 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 consists of 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 September 2022 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 September 28, 2022, 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.
The samples were analyzed for the list of parameters and constituents outlined in the WQMP
and guidance from the NCDEQ DWM, Solid Waste Section (SWS). 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 and leachate samples on September 28, 2022. A surface water
sample was not able to be collected because of dry conditions.
• 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.
• 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.

Semiannual Water Quality Monitoring Report — September 2022 Sampling Event
Marshall Steam Station — FGD Residue Landfill (Permit No. 1809-INDUS)
Terrell, North Carolina
3.0 RESULTS
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 surficial flow zone. These contours were
developed by calculating groundwater elevations in each monitoring well using the depth -to -
water measurements taken during the September 2022 monitoring event. In addition, water -
level measurements from nearby groundwater monitoring wells included in other Site
groundwater monitoring programs were used. 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 Fall 2022 water level sweep (August 8, 2022) 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 S. 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
standard. 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 except pH at MS-10 and MS-
12. The pH values at MS-10 and MS-12 are greater than the historical range.
Surface Water
The surface water sample location was dry on September 28, 2022, therefore no sample was
collected. The sample location is shown on Figure 2.

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.

Pace Project No.: 92620222
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.

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 (Duke) -Analyte detected above the MDL, but below the RL; analyte concentration should be considered an estimate.
7
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 10x the blank concentration.
• MW-1 not collected due to dry well.
• Calcium (0.014 mg/L) was detected in the Equipment Blank; Calcium was not detected in the samples at concentrations less than lox the blank concentration.
• Nitrate (0.03 mg/L) and Nitrate as N (0.01 mg-N/L) were detected in the Field Blank; Nitrate and Nitrate as N were not detected in the samples at concentrations less than 10x the blank
concentrations.

Program Comments:
Note: This is a revised report that supersedes the original dated 10/18/2022. Due to significant figure limitations to the test
code for nitrate as N, the equipment blank result was reported as 0 J. The actual result has been manually entered.
QC Note: A constant weight (method requirement) could not be achieved for TDS sample MS-15.
Data Flags & Calculations:
Any analytical tests or individual analytes within a test flagged with a Qualifier indicate a deviation from the method quality
system or quality control requirement. The qualifier description is found at the end of the Certificate of Analysis (sample results)
under the qualifiers heading. All results are reported on a dry weight basis unless otherwise noted. Subcontracted data
included on the Duke Certificate of Analysis is to be used as information only. Certified vendor results can be found in the
subcontracted lab final report. Duke Energy Analytical Laboratory subcontracts analyses to other vendor laboratories that have
been qualified by Duke Energy to perform these analyses except where noted.
Data Package:
This data package includes analytical results that are applicable only to the samples described in this narrative. An estimation of
the uncertainty of measurement for the results in the report is available upon request. This report shall not be reproduced, except
in full, without the written consent of the Analytical Laboratory. Please contact the Analytical laboratory with any questions. The
order of individual sections within this report is as follows:
Job Summary Report, Sample Identification, Technical Validation of Data Package, Analytical Laboratory Certificate of Analysis,
Analytical Laboratory QC Reports, Sub -contracted Laboratory Results, Customer Specific Data Sheets, Reports &
Documentation, Customer Database Entries, Test Case Narratives, Chain of Custody (COC)
Certification:
The Analytical Laboratory holds the following State Certifications : North Carolina (DENR) Certificate #248, South Carolina
(DHEC) Laboratory ID # 99005. Contact the Analytical Laboratory for definitive information about the certification status of
specific methods.

QUALIFIERS
Project: J22080352 MSS LF
Pace Project No.: 92628383
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.
ANALYTE QUALIFIERS

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.
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.
7
lg (Pace) - Constant weight could not be achieved for this sample after 4 drying cycles. The final weight change was 0.0018 g.
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.
• Achieving constant weight for TDS sample MS-15 was not possible, result should be considered an estimate (lg).
• Mercury (0.024 ug/L) was detected in several Method Blanks; Mercury was also detected in the samples at concentrations less than lox the blank concentrations.
• The RPD between MS-9 and the field duplicate is greater than 35% for Nitrate (0.88/2.8 mg/L) and Nitrate as N (0.20/0.63 mg/L).
• Per Duke Lab, the test code is set up to report Nitrate as N with two significant figures; the actual result for the Equipment Blank is 0.004 J mg-N/L.
• Nitrate as N (0.004 mg-N/L), Mercury (0.01 ug/L), Calcium (0.033 mg/L), and Iron (0.005 mg/L) were detected in the Equipment Blank; Nitrate as N, Mercury, Calcium, and Iron were also
detected in the samples at concentrations less than lox the blank concentrations.
• Mercury (0.01 ug/L), Boron (0.005 mg/L), and Chromium (0.38 ug/L) were detected in the Field Blank; Mercury, Boron, and Chromium were also detected in the samples at concentrations less
than lox the blank concentrations.
• Revised report issued 10/31/2022. Due to significant figure limitations to the test code for Nitrate as N, the equipment blank result was reported as 01 The actual result has been manually
entered.
