Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
EXECUTIVE SUMMARY
SynTerra Corporation (SynTerra) prepared this annual effectiveness monitoring report
for Duke Energy Carolinas, LLC (Duke Energy). The purpose of this report is to provide
effectiveness monitoring updates for the accelerated remediation groundwater
extraction system at the Belews Creek Steam Station (Belews Creek, Site) in Belews
Creek, North Carolina, during the period of operation from April 2019 to April 2020.
The Site is owned by Duke Energy.
ES.1 Introduction
A Settlement Agreement between the North Carolina Department of Environmental
Quality (NCDEQ) Division of Water Resources (DWR) and Duke Energy (September,
2015) required Duke Energy to implement accelerated remediation to address off -site
groundwater impacts. At the time, data from groundwater monitoring indicated
migration of constituent of interest (COIs) in groundwater northwest of the basin, on a
2.67-acre parcel (Parcel A) not owned by Duke Energy. On March 4, 2020, Duke Energy
acquired Parcel A. As a result, identified groundwater migration from the ash basin to
the northwest is within Duke Energy's property boundary. The objective of the
accelerated remediation groundwater extraction system is to reduce groundwater
migration from the ash basin to the northwest. The accelerated groundwater interim
action included the installation of 10 extraction wells at the northwest corner of the ash
basin. System installation was completed in November 2017 and system startup
commenced on March 14, 2018. The system has been in operation continuously since
that time, excluding downtime for maintenance and repair.
Decanting of the free water within the ash basin began in March 2019 as part of the
basin closure process. The reduction in the hydraulic head in the basin has allowed the
natural groundwater divide northwest of the ash basin to reform, such that now Parcel
A is upgradient of the basin and groundwater from the basin no longer flows toward
the area. The groundwater extraction system adds hydraulic control at the northwest
corner of the ash basin to reduce COI concentrations in groundwater in the area.
ES.2 Key Findings
Over the period of operation from April 2019 to April 2020, the following are key
indicators of the accelerated remediation groundwater extraction system's effectiveness:
• Between the start of operation of the ten groundwater extraction wells in March
2018 and April 2020, approximately 10,810,890 gallons of groundwater have been
extracted by the groundwater extraction system.
Page ES-1

Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
• The groundwater extraction system is operating within system settings. The total
average system extraction flow rate is approximately 10 gallons per minute
(gpm), which is approximately 2 gpm less than the previous operating year. The
decrease in extraction flow rates can be attributed to ash basin decanting and the
lowering of the hydraulic head in the area.
• The system is continuously monitored and evaluated for improvement, using
water level data from transducers installed in extraction wells and data from the
remote monitoring system. Since startup, system settings have been adjusted,
generally to a lower target water level depth, to maintain or improve the
effectiveness of the system under changing Site conditions.
• Extraction wells have effectively maintained water levels lower than static
conditions. Lower groundwater levels indicate sustained localized hydraulic
control in the northwest area adjacent to the ash basin.
• Groundwater levels in monitoring wells northwest of the ash basin have been
reduced. Based on Site data, multiple hydraulic variables are affecting
groundwater conditions northwest of the ash basin, including groundwater
extraction and ash basin decanting.
• Based on statistical evaluation, ash basin decanting is the primary hydraulic
variable responsible for reduced water levels northwest of the ash basin. Ash
basin decanting has reduced the hydraulic head of the ponded water by
approximately 16 feet since decanting commenced in March 2019. Completion of
decanting is projected to occur by September 2020.
• Statistical evaluation suggests that the groundwater extraction system appears to
be partially responsible for reduced water levels in effectiveness monitoring
wells CCR-2S/D, EXOB-1, EXOB-2, and GWA-20SA/D.
• As a result of ash basin decanting, a natural hydraulic divide has started to
reform northwest of the ash basin, along the topographic ridgeline represented
by Middleton Loop. The reformation of the divide has hydraulically separated
the ash basin and the extraction system from the area northwest of the ash basin
by diverging groundwater flow directions along the divide.
• Estimated mass removal rates indicate that the extraction system is removing a
significant constituent mass from a localized area northwest of the ash basin. As
of April 2020, the extraction system has removed an estimated 800 pounds of
boron, the primary Constituent of Interest (COI) for the Site.

Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
Due to the acquisition of Parcel A and decanting the basin, groundwater migration no
longer occurs from the ash basin to off -site property. However, SynTerra recommends
that the groundwater extraction system remain operational to maintain localized
hydraulic control in the area as an interim measure prior to initiation of the Corrective
Action Plan (CAP) for the basin (SynTerra, 2019b).
To effectively maintain the system and improve the effectiveness monitoring network
additional recommendations are as follows:
• Evaluate improvements to extraction wells that produce low flow rates and have
water levels greater than 5 feet above the screen.
• Shut off extraction wells if groundwater levels are reduced below the screened
interval from ash basin decanting.
• Improve the effectiveness monitoring network by removing the monitoring wells
that are hydraulically separated from the system by the newly reformed
hydraulic divide.
Once there is hydraulic control northwest of the ash basin from operation of the CAP
system, SynTerra recommends evaluating the effectiveness and benefit of continuing
operation of the accelerated remediation groundwater extraction system. Termination
of system operations will be considered.

1.0 INTRODUCTION
Duke Energy Carolinas, LLC (Duke Energy), owns and operates the Belews Creek
Steam Station (Belews Creek, the Site), located on Belews Reservoir in Stokes County,
North Carolina (Figure 1-1). Belews Creek began operations in 1974 and currently
operates two coal-fired units. The Site, including the station and supporting facilities,
encompasses approximately 700 acres and lies within a 6,100-acre parcel owned by
Duke Energy. Coal combustion residuals (CCR) and other waste water from the coal
combustion process were sluiced to the ash basin until 2018, when all wastewater flows
to the ash basin were discontinued.
The Belews Creek coal ash basin meets the requirements for a "low -risk" classification
in accordance with North Carolina House Bill 630 signed into law in July 2016. Under
the North Carolina General Statutes (G.S.), as amended by the Coal Ash Management
Act (CAMA) of 2014, a low -risk coal CCR surface impoundment might, at the election
of North Carolina Department of Environmental Quality (NCDEQ), be closed by
excavation, closure in place, or a hybrid approach by December 31, 2029. A Consent
Order (CO), between Duke Energy and NCDEQ was finalized on February 5, 2020. The
CO specifies obligations for Duke Energy to excavate and remove all coal ash from the
ash basin. In recognition of the complexity and magnitude of the management and
closure of a CCR surface impoundment, closure of the Belews Creek ash basin will be
now be required by 2031, per G.S. Section 130A-309.215(a).
Duke Energy submitted a final closure plan to NCDEQ on December 31, 2019. The
closure plan includes details for closing the coal ash basin by excavating ash and
placing the ash in a lined landfill partially within the footprint of the former ash basin.
In 2018, initial steps were taken for closing the ash basin, including decommissioning
ash conveyance piping, both for fly ash and bottom ash. On March 27, 2019, ash basin
decanting (removal of ponded water) began and has been ongoing since March 2019.
Completion of decanting is projected to occur during or before September 2020. Ash
basin dewatering will occur after decanting is complete to continue the ash basin
closure process. Effluent discharge from the coal ash basin decanting and dewatering
system is permitted by the NCDEQ Division of Water Resources (DWR) under the
National Pollutant Discharge Elimination System (NPDES) Permit NC0024406. The
permitted outfall (Outfall 006) is located north of the ash basin and discharges to the
Dan River (Figure 1-1).

A settlement agreement between NCDEQ DWR and Duke Energy signed on September
29, 2015, requires accelerated groundwater interim action during the ash basin closure
process. Accelerated remediation was implemented at sites where off -Site groundwater
migration of constituents of interest (COIs) had been detected.
Data from groundwater monitoring indicated the migration of groundwater from the
ash basin to a 2.67-acre off -Site parcel (Parcel A) located adjacent to the northwest
corner of the ash basin (SynTerra 2019a and 2019b), that was not owned by Duke
Energy at the time.
On September 1, 2017, Duke Energy submitted a Basis of Design Report (100% Submittal)
to NCDEQ; the basis of design report (BOD) provides the final details of the accelerated
remediation groundwater extraction system to address off -Site groundwater migration
toward Parcel A ( SynTerra, 2017a).
NCDEQ granted approval to install a groundwater extraction system in October 2017
and approved the BOD report in February 2018. System installation was completed at
the end of November 2017, and system startup commenced on March 14, 2018.
On March 4, 2020, Duke Energy acquired Parcel A. As such, identified groundwater
migration from the ash basin to Parcel A is within Duke Energy's property boundary;
therefore, there is no off -Site groundwater migration related to the Belews Creek ash
basin.
Figure 1-2 illustrates Site features, with the former Parcel A boundary, and shows the
general area for the accelerated remediation groundwater extraction system.
1.1 Objective and Purpose
Constituents associated with coal ash have been identified within groundwater
northwest of the ash basin (SynTerra 2017a and 2019b). The original objective of the
accelerated remediation groundwater extraction system was to address off -Site
groundwater effects by reducing groundwater migration from the ash basin to the
northwest. Groundwater extraction provides a hydraulic boundary control in the
northwest corner of the ash basin.
With the decanting of the ash basin and the lower hydraulic head near the northwest
corner of the basin, the natural groundwater divide along the topographic ridge has
reformed which also provides hydraulic boundary control in the northwest corner of
the basin. The combination of the extraction system operation and ash basin decanting
prevent additional COI migration in groundwater to the northwest.

Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
Conceptual Site Model
The Belews Creek Conceptual Site Model (CSM) provides a current understanding of
the distribution of CCR constituents interacting with the Site -specific
geology/hydrogeology and geochemical processes that control the migration and
potential presence of constituents in various media. A detailed CSM for the ash basin is
provided in the Belews Creek Corrective Action Plan (CAP) Update (SynTerra, 2019b).
The following presents a general summary of the CSM and updates, based on new data,
related to the area northwest of the basin and the groundwater extraction system:
• Topographic ridges located upgradient (south) and side -gradient (east and west)
of the basin reflect hydraulic divides.
• The predominant direction of groundwater flow at the Site is to the north.
Groundwater flow paths (the area of potential constituent migration in
groundwater from the ash basin) remain primarily in the stream valley system of
the ash basin.
• Exceptions to this occur when relatively thin topographic features (e.g., narrow
hydraulic divides) are located downgradient and adjacent to the ash basin. The
ash basin former operating water level was approximately 750 feet North
American Vertical Datum of 1988 (NAVD 88). The ash basin ponded water was
elevated relative to natural groundwater levels. The hydraulic pressure head of
the basin created a hydraulic gradient acting as a driving mechanism for
constituent migration northwest of the ash basin (Figure 1-3).
• From March 26, 2019, when decanting operations began, to April 6, 2020, the
level of ponded water in the ash basin has reduced by approximately 16 feet.
Measured groundwater elevations in monitoring wells northwest of the ash
basin are lower as a result of decanting (Figure 1-3 and Figure 1-4).
• As a result of active ash basin decanting, and supported by new groundwater
elevation data, a natural hydraulic divide has reformed northwest of the ash
basin along the topographic ridgeline where Middleton Loop is located
(Figure 1-4).
• The reformation of the divide has hydraulically separated the ash basin and the
extraction system from the area northwest of the ash basin by diverging
groundwater flow directions along the divide.
• In the northwest area, a portion of the groundwater flow direction has reversed
from northwest in April 2019 to southeast in April 2020 (Figure 1-3 and Figure 1-
4).
Page 1-3

Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
• Generally, the physical setting for an ash basin within a perennial stream valley
limits the horizontal and vertical migration of constituents to areas near and
directly downstream of the basin dam.
• Boron is the primary CCR indicator constituent for groundwater migration from
the ash basin. Boron concentrations greater than North Carolina Administrative
Code (NCAC), Title 15A, Subchapter 02L, Groundwater Classification and
Standards (02L) occur approximately 750 feet beyond the northwest portion of
the ash basin waste boundary. The distribution of other CCR-related constituents
northwest of the ash basin are generally confined within the extent of the boron
plume, with distributions in localized footprints relative to the northwest waste
boundary of the ash basin.
• The reformation of the natural hydraulic divide, northwest of the ash basin, will
limit the migration of constituents in groundwater northwest of the ash basin.
Additionally, horizontal groundwater migration from the ash basin is further
limited by streams downgradient of the northwest corner of the ash basin, which
act as groundwater discharge zones.
To characterize and evaluate the effect of the groundwater extraction system on the
groundwater flow system, nine groundwater monitoring wells were selected as the
effectiveness monitoring network. The nine groundwater monitoring wells are located
in the shallow and deep flow zones, in the vicinity of the groundwater extraction
system (Figure 1-2). Effectiveness monitoring network wells are listed below:
• CCR-2S
• GWA-20SA
• CCR-2D
• GWA-20D
• EXOB-1
• GWA-21D
• EXOB-2
• GWA-27D
• GWA-11D
Constituents of interest (COIs) are those constituents detected at concentrations in
groundwater greater than applicable North Carolina groundwater standards [02L;
Interim Maximum Allowable Concentrations (IMAC); or background threshold values
(BTVs), whichever is greater]. Site COIs were identified in the CSA Update (SynTerra,
2017b) and evaluated in the CAP Update (SynTerra, 2019b) through a COI management
process.
Northwest of the ash basin waste boundary, constituents with concentrations greater
than 02L/IMAC or BTV, whichever is greater, include antimony, arsenic, beryllium,
Page 1-4

Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
boron, chloride, cobalt, iron, manganese, molybdenum, strontium, total dissolved solids
(TDS), and thallium. A summary of groundwater analytical results for effectiveness
monitoring wells and extraction wells is discussed in Section 2.2.
1.2 Groundwater Site Conditions
The ash basin was constructed within a former perennial stream valley in the Piedmont
of North Carolina. The valley topography provides natural hydraulic control of
groundwater flow direction within the former stream valley system. The predominant
direction of groundwater flow at the Site is to the north. There was a component of flow
to the northwest due to the former hydraulic head of the ponded water in the ash basin.
However, ash basin decanting has reduced the hydraulic head and altered the
groundwater flow direction away from the northwest and toward the north.
Three hydrostratigraphic flow zone units identified at the Site are as follows:
• Shallow Flow Zone (S) — Composed of regolith (including residual soils, fill and
reworked soils, alluvium, and saprolite). In the flow and transport model,
calibrated shallow flow zone hydraulic conductivity ranges from 0.05 feet per
day to 4 feet per day (Falta, et al., 2019).
• Deep Flow Zone (D) — A relatively transmissive zone composed mostly of
partially weathered rock that is gradational between saprolite and competent
bedrock. The unit is hydraulically connected to the upper shallow
hydrostratigraphic unit. In the flow and transport model, calibrated deep flow
zone hydraulic conductivity ranges from 0.01 feet per day to 7.0 feet per day
(Falta, et al., 2019).
• Bedrock Flow Zone (BR) — Composed of fractured competent bedrock, which is
confined, except for fractures in the bedrock, from the shallow and deep
hydrostratigraphic units. The majority of water -producing fracture zones are
found within the top 50 feet of competent rock. The water -bearing fractures
encountered in upper bedrock are only mildly productive; in the flow and
transport model, calibrated upper bedrock flow zone hydraulic conductivity
ranges from 0.0002 feet per day to 0.7 feet per day (Falta, et al., 2019).
Water levels from each hydrostratigraphic zone are used to determine the groundwater
flow direction. Water levels are recorded during a 24-hour period. Groundwater
elevations for monitoring wells and extraction wells in the northwest area are based
upon water levels measured during water level gauging events in April 2019 and April
2020 and are provided in Table 1-1. The deep flow zone is the primary flow system
targeted by the groundwater extraction system. Deep flow zone water level maps
Page 1-5

Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
focusing on the northwest area are included for April 2019 (Figure 1-3) and April 2020
(Figure 1-4). The flow direction for the shallow flow zone and bedrock flow zone would
be similar to the deep flow zone due to the unconfined nature of the units, however,
groundwater movement in the bedrock flow zone occurs in secondary porosity
represented by fractures, and is generally slower to respond to changes in groundwater
conditions.
Source Control (Ash Basin Decanting and Dewatering)
Ash basin decanting commenced on March 27, 2019. Decanting is lowering, and
eventually intended to remove, the hydraulic head of the ash basin. Completion of
decanting is projected to occur by September 2020. Ash basin dewatering will occur
after decanting is complete to facilitate ash removal. Decanting is a form of active
source remediation and is considered a critical component of reducing constituent
migration from the ash basin.
Ash basin decanting has reduced the hydraulic head of the ponded water by
approximately 12 feet from April 2019 to April 2020 (Table 1-1) and approximately 16
feet since decanting commenced in March 2019. As a result of decanting, April 2020
groundwater elevation data indicates a natural hydraulic divide has reformed
northwest of the ash basin. The reformation of the hydraulic divide indicates the
groundwater flow system is returning to its more natural condition, with groundwater
from the ash basin primarily flowing north within the basin's stream valley system
(Figure 1-4).
Interim Response Actions
The acquisition of Parcel A was an original objective outlined in the Interim Action Plan
(HDR, 2016a). On March 4, 2020, Duke Energy acquired Parcel A. As a result,
groundwater migration from the ash basin now occurs within Duke Energy's property
boundary; therefore, there are no off -Site groundwater effects identified as being
attributable to the Belews Creek ash basin.
1.3 System Overview
Ten (10) groundwater extraction wells (identified as EX-1 through EX-10) were installed
in the northwest corner adjacent to the ash basin. Extraction wells were installed in
accordance with the specifications described in the Basis of Design Report (100%
Submittal) (SynTerra 2017a).
Wells are configured in a linear pattern, spanning a length approximately 700 feet and
spaced approximately 85 feet apart. Boreholes were drilled approximately 5 feet into the
upper bedrock at depths between 55 and 65 feet. The well screens are 10 feet long, and
Page 1-6

Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
were installed to the bottom of the transition zone to provide capture in the targeted
flow zone. The system layout is provided as Figure 1-2.
The installation included well vaults, which each contain an electromagnetic flow
meter, submersible level transmitter, and pump controller. The pumps are controlled
with individual controllers that use high and low water level sensors to cycle operation
of the pumps as necessary to maintain set drawdown levels. The extraction well header
pipe connects all of the well discharges for direct discharge into the decanting treatment
system, located approximately 50 feet from the header pipe and extraction well EX-1
(Figure 1-2).
Complete system startup commenced on March 14, 2018. The specific details for the
system elements are included in the Basis of Design Report (100% Submittal) (SynTerra
2017a) and the Operations and Maintenance Manual — Interim Groundwater Remediation
System (SynTerra 2018).
The system is set to maintain target water level depths for each well, which currently
reduce the water levels within extraction wells to 15 feet or greater below static water
levels (recorded in November 2017) and are interpreted as the datum for pre -extraction
conditions, from here on out referred to as baseline conditions (SynTerra, 2018).
Since startup, the system is continuously monitored and evaluated for improvement.
The system settings have been adjusted over the course of five times to maintain system
performance under changing Site conditions. Each time the system has been adjusted,
NCDEQ has been notified. Details of system adjustments are included in Section 2.1.1.
The system's current target water level settings were last adjusted on February 27, 2020,
and are provided on Table 1-2.
System Design Alterations
The extraction system discharge line was initially routed to the ash basin. In early 2019,
the discharge line and discharge location were rerouted and modified in preparation for
ash basin closure and decanting. The new discharge location was routed to directly
discharge into the ash basin discharge tower structure via the ash basin dewatering line
(SynTerra, 2019a).
Later in 2019, the extraction system's central discharge line was merged with the ash
basin dewatering effluent line. The point where the extraction system's central
discharge line and ash basin dewatering line merge was rerouted in spring 2020 to the
influent of the treatment system. The rerouting of the pipe was implemented to
maintain operation of the groundwater extraction system, while also complying with
Page 1-7

Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
NPDES permit modifications and improve treatment of the ash basin decanting and
dewatering system. Further details of the system modification are included in
Section 3.0 and Appendix A.
System Effectiveness Monitoring Network
The primary flow zone targeted by the groundwater extraction system is the deep flow
zone or transition zone, consisting of a saprolite and weathered fractured bedrock. To
monitor the effectiveness of the hydraulic control of the system in the vicinity of the
extraction wells, data logging pressure transducers are installed in select monitoring
wells to record hourly water level measurements. The effectiveness monitoring wells
include CCR-2S/D, EXOB-1 and EXOB -2, GWA-111), GWA-20SA/D, GWA-211), and
GWA-27D. Monitoring wells were selected to represent the potential area of influence
of the extraction system. The effectiveness monitoring well layout is provided as
Figure 1-2.
All wells are screened in the deep flow zone, with the exception of CCR-2S and GWA-
20SA, which are screened in the shallow flow zone. Monitoring wells CCR-2S and
GWA-20SA are the nearest shallow flow zone wells to the extraction system. The deep
and shallow hydrostratigraphic flow zones are unconfined; therefore, the two shallow
flow zone monitoring wells nearest the extraction system are used for monitoring
effects to the upper hydrostratigraphic unit.

2.0 SYSTEM EFFECTIVENESS
The effectiveness of the groundwater extraction system is evaluated through
monitoring groundwater elevation and groundwater constituent concentrations from
the extraction wells and the effectiveness monitoring network wells. The system is
designed to provide hydraulic control through:
• Drawdown of groundwater elevation
• Achievement of hydraulic boundary control near the extraction well system
• Removal of constituent mass from the groundwater system to reduce migration
of CCR constituents.
Annual groundwater extraction system effectiveness is evaluated by comparing
baseline conditions of the Site taken before the startup of the system, previous annual
Site conditions, and current Site conditions. If adjustments to the system have been
made that have resulted in significant changes to the effectiveness of the groundwater
extraction system, information before and after adjustments can be compared.
Routine or annual information collected to support this evaluation includes:
• Weekly Groundwater Extraction System Performance Inspection
o Groundwater extraction system inspection weekly total flow, average
pump pressure, and average water level readings (Table 2-1)
• Groundwater Hydraulic Monitoring
o Water level data from pressure transducers installed in extraction wells
EX-1 through EX-10 (Figure 2-1 through Figure 2-5)
o Water level data from pressure transducers installed in monitoring wells
CCR-2S/D, EXOB-1, EXOB -2, GWA-111), GWA-20SA/D, GWA-211), and
GWA-27D (Figure 2-7 through Figure 2-11)
• Groundwater Analytical Monitoring
o Annual groundwater monitoring data from extraction wells EX-1 through
EX-10 (Table 2-2)
o Semiannual or quarterly groundwater monitoring data from monitoring
wells CCR-2S/D, EXOB-1, EXOB -2, GWA-111), GWA-20SA/D, GWA-211),
and GWA-27D (Table 2-2)

2.1 Groundwater Hydraulic Monitoring
2.1.1 Monitoring Well Hydraulic Evaluation
To monitor the effectiveness of hydraulic control near to the extraction system,
data logging pressure transducers are installed in effectiveness monitoring wells
CCR-2S/D, GWA-11D, GWA-20SA/D, GWA-21D, GWA-27D, EXOB-1, and
EXOB-2. Data is downloaded, and manual water level measurements are
collected monthly.
Groundwater elevations were measured during water level -gauging events in
April 2019 and April 2020 and are provided in Table 1-1. Deep flow zone water
level maps focusing on the northwest area are included for April 2019 (Figure 1-
3) and April 2020 (Figure 1-4). From April 2019 to April 2020, water levels are
reduced below static water levels in groundwater monitoring wells northwest of
the ash basin, including effectiveness monitoring wells. The inferred area of
influence of the groundwater extraction system is determined by the localized
area where water levels are reduced below static water levels around the
extraction wells.
As of April 2020, the groundwater extraction system has been operational for
approximately two years. Data downloaded from pressure transducers in the
effectiveness monitoring wells is used to evaluate changes in water levels during
the period from baseline conditions to current conditions. Water levels recorded
in January 2018 are interpreted as the datum for baseline conditions.
Regarding effectiveness monitoring wells, hydrographs of water level elevations
are included on Figure 2-7 through Figure 2-11. Effectiveness monitoring well
water levels have decreasing trends, and water levels in wells CCR-2S and GWA-
20SA are below the transducers.
There are multiple hydraulic variables that affect the groundwater flow system
in the area northwest of the ash basin. Correlation matrices are used to evaluate
linear associations between changes in water level data from effectiveness
monitoring wells and operation of the groundwater extraction system, as well as
two other identified hydraulic variables. Hydraulic variables and datasets used
to conduct correlation matrices include:
• Effectiveness monitoring well - water elevation (feet NAVD 88)
• Groundwater extraction - total cumulative flow (gallons)
• Ash basin decanting - water elevation (feet NAVD 88)
Page 2-2

Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
Generally, correlation coefficients between +/- 0.5 and +/- 0.75 (unitless) indicate a
moderate linear association. Correlation coefficients greater than +/-0.75 indicate
a strong linear association. Correlation matrices for each effectiveness monitoring
well and hydraulic variables are included in Appendix B. Correlations results
are discussed in the remainder of this subsection.
Groundwater Extraction
The groundwater extraction system removes groundwater from the flow system
and draws down water levels in a localized area near the system. Total
cumulative flow from the groundwater extraction system increases over time,
and therefore is a progressive measurement to evaluate the relationship with
changes in monitoring well water elevations over time. A negative linear
association between the two variables suggests that as groundwater extraction
total cumulative flow increases, monitoring well water levels decrease.
In order of greatest to least, effectiveness monitoring wells that have a strong
negative linear association with groundwater extraction total cumulative flow
are CCR-2S, EXOB-2, GWA-20SA, EXOB-1, CCR-2D, and GWA-20D (correlation
coefficient range: -0.808 to-0.885; Appendix B).
Effectiveness monitoring well GWA-27D has a moderately negative linear
association with groundwater extraction total cumulative flow (correlation
coefficient:-0.735; Appendix B).
Effectiveness monitoring wells GWA-11D and GWA-21D do not appear to have
a significant linear association with groundwater extraction total cumulative
flow (correlation coefficient range: 0.152 to-0.001; Appendix B).
Ash Basin Decanting
Ash basin decanting lowers the ponded water head of the ash basin, reducing the
hydraulic pressure on the groundwater flow system and lowering groundwater
levels in areas hydraulically connected to the ash basin. Water elevation from the
ash basin decreases over time and, therefore, is a progressive measurement to
evaluate the relationship with changes in monitoring well water elevations over
time. A positive linear association between the two variables suggests that while
ash basin water elevation decreases, monitoring well water levels also decrease.
After decanting, all nine effectiveness monitoring wells have a strong positive
linear association with the decreasing ash basin water level.
Page 2-3

Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
Monitoring well EXOB-2 has the highest correlation coefficient, and monitoring
well GWA-21D has the lowest correlation coefficient (correlation coefficient
range: 0.985 to 0.775; Appendix B).
Effectiveness monitoring wells CCR-2S/D, EXOB-1, EXOB-2, and GWA-20SA/D
are located southwest of the hydraulic divide and nearest the groundwater
extraction system and ash basin. These wells have a strong correlative association
with both hydraulic variables. This suggests that the groundwater extraction
system might be responsible for some observed drawdown in CCR-2S/D, EXOB-
1, EXOB-2, and GWA-20SA/D.
Effectiveness monitoring wells GWA-11D and GWA-21D are northwest of the
hydraulic divide and furthest from the groundwater extraction system and ash
basin. These wells do not appear to have a correlative association with the
groundwater extraction system.
2.1.2 Extraction Well Hydraulic Evaluation
The groundwater extraction system is continuously monitored and evaluated for
improving performance, using water level data from transducers installed in
extraction wells and retrieved from the remote monitoring system. The system
maintains lower water levels within each well below prescribed target water
elevations. Current settings create 15 feet or greater of drawdown below the
observed static water level (i.e., pre -extraction conditions) across the
groundwater extraction system (Table 1-2). A summary of weekly inspection
data pertaining to the groundwater extraction system can be found on Table 2-1.
Hydrographs depicting groundwater elevation data for extraction wells during
the period December 20, 2018, through April 6, 2020, are provided as Figure 2-1
through Figure 2-5. Remote monitoring system data before December 20, 2018, is
not available due to the replacement of the remote telemetry system in early
December 2018.
Since the startup of the groundwater extraction system, the system settings have
been adjusted, generally to a lower target water level depths to maintain or
improve the effectiveness of the system under changing Site conditions.
Adjusting the settings to lower target water level depths intends to increase
potential drawdown in the area of the groundwater extraction system. The first
system adjustment was made in August 2018; a summary of those adjustments
can be found in the Interim Action 2019 Effectiveness Monitoring Report (SynTerra,
Page 2-4

Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
2019a). The following summarizes the four adjustments to the settings made
from April 2019 to April 2020:
• On September 23, 2019, 'pump -on settings' were lowered by
approximately 2 feet to 4 feet in EX-1, EX-3, EX-4, and EX-6 to increase
cycling of the pump and create more drawdown and increase the
pumping rate, which had decreased in the weeks prior. To maintain a
water level above the screen interval and to prevent biofouling due to
increased cycling of the pump, 'pump -off settings' were increased by 1
foot in EX-6.
• On November 11, 2019, 'pump -on settings' were lowered by
approximately 6 feet in EX-8, EX-9, and EX-10. This was intended to create
more drawdown.
• On January 2, 2020, 'pump -off settings' were lowered in EX-3 by 1.5 feet
the pumping rate after a decrease had been observed in the weeks prior.
The 'pump -off settings' was increased by 3 feet in EX-9 to maintain water
level above the screen interval and prevent biofouling.
• On February 27, 2020, the 'pump -on setting' for extraction well EX-9
pump was increased by 12 feet, and the 'pump -off setting' was increased
by 7 feet to maintain the pumping rate and to keep the water level above
the top of the screen to prevent biofouling.
Annual average water elevations from April 2019 to April 2020, and an average
of water elevation recorded on April 6, 2020 for each well, are below target water
level depths, indicating the system is operating within prescribed system settings
and is effective at maintaining water levels within target settings (Figure 2-1
through Figure 2-5).
Between March 14, 2018 and April 6, 2020, the accelerated remediation
groundwater extraction system has extracted approximately 10,810,890 gallons of
water (Table 1-2). In order of greatest extraction flow rate, extraction wells EX-1,
EX-2, EX-4, and EX-6 produce the highest flows of extracted groundwater. These
four wells account for over 70 percent of the flow from the system. Extraction
wells EX-1, EX-2, EX-4, and EX-6 are located at the northeast end of the system,
within the thicker region of the transition zone, which has an approximate
thickness of 13 feet to 21 feet. Due to the relatively transmissive nature of the
transition zone, saturated thickness of the transition zone is a major factor that
influences the behavior of groundwater. On average, groundwater extraction
Page 2-5

Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
system settings in EX-1, EX-2, EX-4, and EX-6 system are able to maintain
water levels within a 5 foot range — the difference between 'on' and' off' pump
settings — and maintain water levels above the top of the screen, with the
exception of EX-4 which maintains a water level of 0.2 feet above the screen.
Current settings for extraction wells EX-1, EX-2, EX-4, and EX-6 are optimal
because settings maintain water levels within a tightly controlled depth range,
close to the screen interval, and produce high and stable extraction flow rates,
which are the highest in the extraction system.
Extraction wells EX-8 and EX-10 have lower flow rates, accounting for
approximately 5 percent of the flow from the system. Wells EX-8 and EX-10 are
located at the southwest end of the system, where the transition zone thickness
decreases (approximately 5 feet to 20 feet thick). On average, EX-8 and EX-10
system settings maintain water levels within a 16-foot range and maintain water
levels slightly greater than 7 feet above the screen. Current settings for extraction
wells EX-8 and EX-10 continue to be evaluated for increasing the pumping rete
and improving the hydraulic control.
To further evaluate the groundwater extraction systems effectiveness, extraction
flow rates and effectiveness monitoring analytical results (Section 2.2.2) are used
to calculate estimated mass removal rates and mass totals for each extraction
wells in Section 2.3.2.
In summary, the accelerated remediation groundwater extraction system
effectively maintains water levels lower than static conditions and creates
localized drawdown in the area near the system (Figure 1-3 and Figure 1-4).
Extraction wells EX-1, EX-2, EX-4, and EX-6 are producing more extracted
groundwater, while the remaining extraction wells continue to be evaluated for
increasing hydraulic control. Recommendations for adjusting system settings for
extraction wells that could improve the operation are included in Section 4.0.
2.2 Groundwater Analytical Monitoring
Groundwater sampling events for the extraction wells were conducted semiannually in
2018 and annually thereafter (April 2019 and April 2020). Effectiveness monitoring
wells are sampled routinely as part of either the Interim Monitoring Program (IMP) or
the United States Environmental Protection Agency (USEPA) CCR detection monitoring
program. A comprehensive groundwater analytical summary of samples collected from
January 2018 through April 2020 at extraction wells and effectiveness monitoring wells
is presented in Table 2-2. Laboratory reports for extraction well groundwater sampling
events are provided in Appendix C.

2.2.1 Baseline Analytical Results
Extraction Well Results
Groundwater samples for extraction wells EX-1 through EX-10 were collected in
March 2018, one week after system startup. Analytical results show that boron
was detected at concentrations greater than the 02L standard in all extraction
wells, except EX-8.Other COIs that were detected in concentrations greater than
02L/IMAC or BTV, whichever is greater, include antimony, beryllium, cadmium,
chloride, cobalt, iron, manganese, strontium, TDS, thallium, and vanadium
(Table 2-2).
Effectiveness Monitoring Well Results
Groundwater monitoring wells EXOB-1 and EXOB-2 were sampled twice in
December 2017 prior to system startup. The remaining effectiveness monitoring
wells were sampled during the groundwater quarterly sample event in January
2018. These samples are considered baseline analytical results and represent
groundwater quality prior to system startup and operation. Analytical results
show that boron was detected at concentrations greater than the 02L standard in
effectiveness monitoring wells CCR-2S/D, EXOB-1, EXOB-2, GWA-20SA/D and
GWA-27D. In effectiveness monitoring wells GWA-11D and GWA-21D, boron
concentrations were less than the 02L standard. Other COIs detected in
concentrations greater than 02L/IMAC or BTV, whichever is greater, include
arsenic, beryllium, chloride, chromium, cobalt, iron, manganese, molybdenum,
strontium, TDS, thallium, and vanadium (Table 2-2).
2.2.2 Effectiveness Monitoring Analytical Results
Extraction Well Results
Groundwater samples collected from extraction wells EX-1 through EX-10 from
March 2018 to April 2020 show relatively stable constituent concentrations since
the startup and operation of the system (Table 2-2), with the exception of
extraction well EX-9.
Extraction well EX-9 has increasing concentrations of COIs boron, beryllium,
cobalt, manganese, and thallium and decreasing concentrations of iron.
Extraction well EX-9 was serviced to clean the screen of fouling during the week
March 2, 2020. The precipitation of iron, which causes fouling in the screen, is
likely the cause of decreasing iron concentrations. Increasing concentrations of
other constituents is then likely related to less available iron for sorption.

Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
Effectiveness Monitoring Well Results
Groundwater samples collected from effectiveness monitoring wells from June
2016 to April 2020 include up to 18 sample events. Samples collected from April
2018 to April 2020 represent groundwater conditions while the system has been
operational. In general, analytical results collected since the system became
operational have similar constituent concentrations relative to baseline analytical
results (Table 2-2).
Effectiveness monitoring wells CCR-2S/D, EXOB-1, EXOB-2, and GWA-20SA/D
are located southeast of the hydraulic divide and nearest the extraction system.
Since the system has been operational, constituents with concentrations greater
than 02L/IMAC or BTV, whichever is greater, for these wells include antimony,
arsenic, beryllium, boron, cadmium, chloride, chromium, cobalt, iron,
manganese, selenium, strontium, TDS, and thallium (Table 2-2). These wells are
within the ash basin geographic limitation.
Effectiveness monitoring wells GWA-11D, GWA-21D, and GWA-27D are
northwest of the hydraulic divide and furthest from the extraction system. Since
the system has been operational, constituents with concentrations greater than
02L/IMAC or BTV, whichever is greater, for these wells include beryllium, boron,
chloride, cobalt, iron, manganese, strontium, TDS, and thallium (Table 2-2).
Boron Trend Evaluations
Boron is the primary indicator of COI migration at the Site. Boron concentrations
over time in effectiveness monitoring wells are depicted on Figure 2-12.
Monitoring wells are designated as either southeast of Middleton Loop and,
therefore, southeast of the hydraulic divide and nearest the extraction system or
northwest of Middleton Loop, and therefore, beyond the hydraulic divide. Dates
of significant Site changes, including system startup and decanting startup, are
indicated on the plots.
A Mann -Kendall trend analysis was performed on boron results from the nine
effectiveness monitoring wells (Appendix B). The analysis includes the boron
data of each well from June 2016 to April 2020 (Table 2-2). For the analysis to be
statistically significant, at least eight to 10 data points are necessary. Each
monitoring well has 12 or more data points included in the analysis. Results from
the trend analysis include:
Effectiveness monitoring wells EXOB-1 and GWA-20SA have statistically
significant decreasing trends. Wells EXOB-1 and GWA-20SA are located
Page 2-8

Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
near the northeast of the system where the wells with the highest flow
rates (EX-1, EX-2, EX-4, and EX-6) are located. Monitoring well hydraulic
evaluation (Section 2.1.2) concludes that EXOB-1 and GWA-20SA have a
strong negative linear association with groundwater extraction total
cumulative flow. This suggests that the groundwater extraction system's
capture zone extends to these wells, and therefore the groundwater
extraction system might be responsible for some observed drawdown in
effectiveness monitoring wells. Due to the statistically significant
hydraulic correlation, the groundwater extraction system appears to also
be responsible for decreasing boron concentrations.
• Effectiveness monitoring wells GWA-11D and GWA-21D have statistically
significant increasing trends. Wells GWA-11D and GWA-21D are
northwest of the hydraulic divide, and furthest from the groundwater
extraction system. Hydraulic evaluations of monitoring wells (Section
2.1.2) concludes that GWA-11D and GWA-21D do not appear to have a
significant linear association with groundwater extraction total
cumulative flow. This suggests that the groundwater extraction system's
capture zone does not extend to these wells. Due to a lack of significant
hydraulic correlation and an increase in boron concentrations, those wells
appear to be located beyond the localized area of hydraulic control from
the extraction system.
Effectiveness monitoring wells CCR-2S/D, EXOB-2, GWA-20D, and GWA-27D
have stable concentrations, and do not indicate statistically significant trends in
data. Wells CCR-2S/D and EXOB-2 are located near the southwest of the system
where wells with lower flow rates (EX-8 and EX-10) are located. Well GWA-20D
is located near the northeast of the system in the deep flow zone. Well GWA-27D
is located northwest of the hydraulic divide. Hydraulic evaluations of the
monitoring wells (Section 2.1.2) conclude that CCR-2S/D, EXOB-2, GWA-20D,
and GWA-27D have a strong to moderate negative linear association with
groundwater extraction total cumulative flow. This suggests that the
groundwater extraction system's capture zone extends to these wells, and
therefore the groundwater extraction system might be responsible for some
observed drawdown in effectiveness monitoring wells. Although the lack of
statistically significant trends in boron concentrations suggests the hydraulic
influence has yet to result in changes to groundwater chemistry.

2.3 System Performance Metrics
2.3.1 Groundwater Extraction Rates and Drawdown
Between the start of operation of the ten groundwater extraction wells in March
2018 and April 2020, the accelerated remediation groundwater extraction system
has extracted approximately 10,810,890 gallons of water. Since the system
became operational, the average total extraction flow rate for the system is
approximately 10 gallon(s) per minute (gpm), and approximately 8 gpm for the
annual period (April 2019 to April 2020) (Table 1-2).
Extraction flow rates across the 10 wells range from 2.4 gpm (EX-1) to 0.04 gpm
(EX-10). Extraction wells EX-1, EX-2, EX-4 and EX-6 continue to have the highest
flow rates (>0.6 gpm) relative to other extraction wells in the system. However,
flow rates for each well during the current annual period have decreased,
relative to the extraction flow rates of the previous annual period (SynTerra,
2019a), with the exception of extraction well EX-1. Extraction well EX-1 flow rate
has increased by 0.8 gpm. The increase in flow rate was determined to be
attributed to a siphoning effect from merging the central discharge line of the
extraction system and the ash basin dewatering influent line. Siphoning was
mitigated by the replacement of the check valve on EX-1.
Extraction flow rates are dependent on the hydraulic head of the groundwater
system. The groundwater system northwest of the ash basin is highly influenced
by the hydraulic head of the ash basin; therefore, the decrease in extraction flow
rates can be attributed to decanting activities at the ash basin. Decanting
activities have lowered the hydraulic head in the ash basin by approximately 16
feet, reducing overall groundwater levels in the surrounding area (Figure 1-4).
Extraction well EX-6 has the greatest reduction in flow rate from the previous
annual period. This is because EX-6 has the highest screen elevation (729.2 feet
NAVD 88), which is only 4 feet lower than the April 6, 2020, ash basin elevation
(733.6 feet NAVD 88). Based on flow and transport modeling, after ash basin
decanting is complete, the 10 extraction wells are predicted to have significantly
reduced flow rates, with combined system flow rate of approximately 2.5 gpm
(SynTerra, 2019b). Shutting -off extraction wells should be considered if
groundwater levels are reduced below the top of the screen due to ash basin
decanting. Extraction EX-6 and EX-3 have the highest screen elevation relative to
other extraction wells and will likely be initially affected.
Page 2-10

Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
Prior to system operation, static water levels in extraction wells ranged
approximately from 744.2 feet to 748.2 feet NAVD 88 [as reported in Appendix A
of the Operations and Maintenance Manual Interim Groundwater Remediation System
(SynTerra 2018)]. Static water levels were recorded in November 2017 and are
interpreted as the datum for baseline conditions. Total drawdown in each
extraction well is calculated as the difference between baseline conditions to
current conditions.
Relative to static water levels, April 6, 2020 water elevations indicate current
system settings maintain an average drawdown of approximately 15 feet to 35
feet below static water levels across the system (Table 1-2). This is a drawdown
approximately 5 feet greater than the previous annual period and approximately
10 feet greater than the startup period.
The drawdown inferred area of influence due to the groundwater extraction
system is determined by the degree of drawdown in extraction wells relative to
the degree of drawdown in effectiveness monitoring wells (Figure 2-6). The
accelerated remediation groundwater extraction system effectively maintains
water levels lower than static conditions and creates localized drawdown in the
area near the system.
2.3.2 Mass Removal Calculations
Groundwater sampling events for the extraction wells were conducted
semiannually in 2018 and annually thereafter (April 2019 and April 2020).
Groundwater samples are collected from the sample ports at EX-1 through EX-
10. Groundwater analytical results from EX-1 through EX-10 are included on
Table 2-2.
For the purposes of monitoring groundwater quality and affected groundwater
migration at the Site, boron provides a good indication of the occurrence and
distribution of CCR-related COIs due to its relatively greater concentration in
CCR than in native soil and its relatively significant solubility and mobility in
groundwater (Chu, 2017). April 2020 groundwater samples results from EX-1
through EX-10 indicated boron concentrations ranging from 2,160 µg/L (EX-8) to
8,240 µg/L (EX-3).
A summary of estimated mass removal rates and mass totals for each extraction
well sampling period and the total system since startup are presented in Table 2-
3. The calculations provide the estimated quantitative rate at which a constituent
mass has been removed from the groundwater system and is an indicator of the
Page 2-11

Interim Action Plan 2020 Effectiveness Monitoring Report July 29, 2020
Belews Creek Steam Station — Duke Energy Carolinas, LLC SynTerra
effectiveness of the system. Constituent mass removed by the extraction system
is removed from the groundwater system and, therefore, incapable of
contributing to affected groundwater migration.
Mass removal calculations are performed by multiplying boron analytical results
from extraction well EX-1 through EX-10; these results are presented in µg/L by
the average daily flow rate in gallons per day (GPD) and by applying
appropriate unit conversions to estimate mass removal rates in pounds per day.
Estimated mass removed (in pounds) during each period is then calculated by
the number of operational days per period.
Since system startup, the extraction system has removed an estimated 800
pounds of boron, the primary indicator of other COIs at the Site. Observations
from the mass removal calculations include:
Mass removal rates have generally decreased in the extraction wells. This
can be attributed to the decrease in average daily flow rates and a
decrease in boron concentrations (Table 2-3).
In order of greatest mass removal rates, extraction wells EX-1, EX-2, EX-4,
and EX-6 have removed the most mass of boron; each well has removed
more than 100 lbs. of boron as of April 2020 (Table 2-3).
Estimated mass removal rates indicate that the system is operating as designed
and is removing constituent mass from the localized area of influence.

3.0 OPERATIONS AND MAINTENANCE
The extraction system is monitored to assess system performance on an ongoing basis.
Weekly routine system performance monitoring includes a summation of flow per well,
well pump pressure, and extraction well water level. Extraction well system parameter
data can be found on Table 2-1.
There have been few operational or maintenance issues identified and resolved since
the system began operation, according to weekly inspections. An overview of system
operations and maintenance is reported monthly to NCDEQ.
System Design Alterations
The extraction system discharge line was initially routed to the ash basin. In early 2019,
the discharge line and discharge location were rerouted and modified in preparation for
ash basin closure and decanting. The new discharge location was routed to directly
discharge into the ash basin discharge tower structure via the ash basin dewatering
pipe (SynTerra, 2019a). The change had been implemented since further discharge to
the ash basin was not permitted once decanting commenced.
Later in 2019, the extraction system's central discharge line was merged with the ash
basin dewatering effluent line. The point where the extraction system's central
discharge line and ash basin dewatering line merge was rerouted in spring 2020 to the
influent of the treatment system. The rerouting of the pipe was implemented to
maintain operation of the groundwater extraction system, while also complying with
NPDES permit modifications and improve treatment of the ash basin decanting and
dewatering system.
The merger of the central discharge line of the extraction system and ash basin
dewatering effluent line has had insignificant effects on the structural integrity of the
piping associated with either system. The additional extraction of groundwater into the
decanting system has insignificantly affected decanting operations. The system
modifications are depicted in a revised design drawing in Appendix A.

4.0 CONCLUSIONS AND RECOMMENDATIONS
Interim groundwater monitoring indicated the migration of groundwater from the ash
basin to a 2.67-acre parcel (Parcel A) that was off -Site and northwest of the ash basin.
On March 4, 2020, Duke Energy acquired Parcel A. As a result of the March 4, 2020,
acquisition of the parcel, identified groundwater migration from the ash basin to Parcel
A now occurs within Duke Energy's property boundary; therefore, there are no off -Site
groundwater effects identified as being those of the ash basin at the Site. Decanting has
reduced the hydraulic head near the northwest side of the basin and the natural
groundwater divide in the area is reforming. As a result, the groundwater levels have
been lowered in the area and the groundwater flow direction is now to the north rather
than the northwest.
Operation of the groundwater extraction system began on March 14, 2018. The system
has been in operation continuously since that time, excluding downtime for
maintenance and repair. Conclusions from groundwater elevation data, extraction well
flow rates, and laboratory analytical data include the following:
• Between the start of operation of the ten groundwater extraction wells in March
2018 and April 2020, approximately 10,810,890 gallons of groundwater have been
extracted by the groundwater extraction system.
• The groundwater extraction system is operating within design parameters, with
a slight reduction in overall extraction flow rate since the startup of the system.
The total average system extraction flow rate is approximately 10 gallons per
minute (gpm), which is approximately 2 gpm less than the previous operating
year.
• Since the startup of the groundwater extraction system, the settings have been
adjusted five times, generally to a lower target water level depth to maintain or
improve the effectiveness of the system under changing Site conditions.
• The groundwater extraction system effectively maintains water levels
approximately 15 feet to 35 feet lower than static water levels and creates
localized drawdown in the area near the system (Figure 2-6).
• Extraction wells EX-1, EX-2, EX-4, and EX-6 are producing the most flow of

evaluated for increased hydraulic control.

• Since system startup, the extraction system has removed an estimated 800
pounds of boron, the primary indicator COI for the Site. Estimated mass removal
rates indicate that the system is operating as designed and is removing
constituent mass from the localized area of influence.
Although Duke Energy has acquired the property northwest of the ash basin, corrective
action is required in a localized area northwest of the ash basin beyond the geographic
limitation (SynTerra, 2019b). Therefore, SynTerra recommends that the groundwater
extraction system remain operational to maintain localized hydraulic control in the area
as an interim measure prior to initiation of the CAP for the basin (SynTerra, 2019b).
To effectively maintain the groundwater extraction system and improve the
effectiveness monitoring network additional recommendations are as follows:
• Evaluate improvements for drawdown in extraction wells that produce low flow
rates and have water levels greater than 5 feet above the screen (e.g. EX-8 and EX-
10).
• Shut off an extraction well if the groundwater level is reduced below the top of
the well screen from ash basin decanting. Extraction EX-6 and EX-3 have the
highest screen elevation relative to other extraction wells and will likely be
initially affected.
• Continue monitoring effectiveness groundwater monitoring wells, but improve
the effectiveness monitoring network by removing the monitoring wells GWA-
11D and GWA-21D. Statistical evaluation supports that these wells are
hydraulically separated from the system.
Once there is evidence of effective hydraulic control northwest of the ash basin from
operation of the corrective action system, SynTerra recommends that the effectiveness
and benefit of continuing the operation of the accelerated remediation groundwater
extraction system be evaluated and termination of system operations be considered.

1. SITE FEATURES ARE FOR 2020 SITE CONDITIONS.
2. GROUNDWATER MONITORING WELL DRAWDOWN WAS CALCULATED FROM THE
DIFFERENCE IN WATER LEVEL READING FROM JANUARY 15, 2018 (PRE -EXTRACTION
CONDITIONS) TO APRIL 6, 2020 (CURRENT CONDITIONS) (TABLE 1-2).
3. EXTRACTION WELL DRAWDOWN WAS CALCULATED FROM THE DIFFERENCE IN
STATIC EXTRACTION WELL WATER ELEVATIONS, AS REPORTED IN APPENDIX A -
OPERATIONS AND MAINTENANCE MANUAL INTERIM GROUNDWATER REMEDIATION
SYSTEM (SYNTERRA 2018), AND AVERAGE WATER LEVELS RECORDED ON APRIL 6,
2020.
4. ASH BASIS DRAWDOWN WAS CALCULATED FROM THE DIFFERENCE IN FORMER
OPERATING HEAD ELEVATION AND APRIL 6, 2020 ELEVATION.
5. ELEVATIONS ARE REFERENCED TO THE NORTH AMERICAN VERTICAL DATUM 88
(NAVD 88).
6. THE TOPOGRAPHY IS SHOWN FOR REFERENCE PURPOSES ONLYAND SHOULD
NOT BE USED FOR DESIGN OR ENGINEERING PURPOSES. TOPOGRAPHY IS BASED
ON LIDAR BARE EARTH DATA OBTAINED FROM THE NORTH CAROLINA SPATIAL DATA
SITE AT https://sdd.nc.gov/sdd/DataDownload.aspx.
7. THE WATERS OF THE U.S. DELINEATION HAS NOT BEEN APPROVED BY THE US
ARMY CORPS OF ENGINEERS AT THE TIME OF THE MAP CREATION. TH IS MAP IS NOT
TO BE USED FOR JURISDICTIONAL DETERMINATION PURPOSES. THE WETLANDS AND
STREAMS BOUNDARIES WERE OBTAINED FROM STREAM AND WETLAND

Notes:
' - Background threshold values were calculated using data from background groundwater samples collected June 2015 to April 2017
2 - Background threshold values were calculated using data from background groundwater samples collected October 2010 to December 2018 and submitted to NCDEQ June 2019
O - Bold highlighted concentration indicates exceedance of the 15A NCAC 02L .0202 Standard or the IMAC. (Effective date for 15A NCAC 02L .0202 Standard and IMAC is April 1, 2013)
* - Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April, 1, 2013.
< - concentration not detected at or above the adjusted reporting limit.
1g - Result confirmed by second analysis performed out of hold.
E - Analyte concentration exceeded the calibration range. The reported result is estimated.
L3 - Analyte recovery in the laboratory control sample (LCS) exceeded quality control (QC) limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
U - Analyte was analyzed for, but not detected above the MDC.
S1 - Data review findings indicate result may be unreliable. Use with caution.
Deg C - Degrees Celsius
j - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
M6 - Matrix spike and Matrix spike duplicate recovery not evaluated against control limits due to sample dilution.
M2 - Matrix spike recovery was Low: the associated Laboratory Control Spike (LCS) was acceptable.
Ml - Matrix spike recovery was High: the associated Laboratory Control Spike (LCS) was acceptable.
pmhos/cm - Micro mhos per centimeter
pg/L - Micrograms per liter
mg/L - Milligrams per liter
pg/mL - Micrograms per milliliter
my - Millivolts
NTU - Nephelometric turbidity unit
NA - Not analyzed
NE - Not established
NM - Not measured
pCi/L - picocuries per liter
R1 - Relative Percent Difference (RPD) value was outside control limits.
P4 - Sample field preservation does not meet EPA or method recommendations for this analysis.
D3 - Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
Spec Cord - Specific Conductance
S.U. - Standard Unit
B - Target analyte detected in method blank at or above the reporting limit. Target analyte concentration in sample is less than SOX the concentration in the method blank. Analyte concentration in sample could be due to blank contamination.
Temp - Temperature
RO - The data are unusable. The sample results are rejected due to serious deficiencies in meeting QC criteria. The analyte may or may not be present in the sample.
N2 - The lab does not hold accreditation for this parameter.
D6 - The relative percent difference (RPD) between the sample and sample duplicate exceeded laboratory control limits.
M4 - The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level. The associated Laboratory Control Spike recovery was acceptable.

Notes:
' - Background threshold values were calculated using data from background groundwater samples collected June 2015 to April 2017
2 - Background threshold values were calculated using data from background groundwater samples collected October 2010 to December 2018 and submitted to NCDEQ June 2019
O - Bold highlighted concentration indicates exceedance of the 15A NCAC 02L .0202 Standard or the IMAC. (Effective date for 15A NCAC 02L .0202 Standard and IMAC is April 1, 2013)
* - Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April, 1, 2013.
< - concentration not detected at or above the adjusted reporting limit.
1g - Result confirmed by second analysis performed out of hold.
E - Analyte concentration exceeded the calibration range. The reported result is estimated.
L3 - Analyte recovery in the laboratory control sample (LCS) exceeded quality control (QC) limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
U - Analyte was analyzed for, but not detected above the MDC.
S1 - Data review findings indicate result may be unreliable. Use with caution.
Deg C - Degrees Celsius
j - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
M6 - Matrix spike and Matrix spike duplicate recovery not evaluated against control limits due to sample dilution.
M2 - Matrix spike recovery was Low: the associated Laboratory Control Spike (LCS) was acceptable.
Ml - Matrix spike recovery was High: the associated Laboratory Control Spike (LCS) was acceptable.
pmhos/cm - Micro mhos per centimeter
pg/L - Micrograms per liter
mg/L - Milligrams per liter
pg/mL - Micrograms per milliliter
my - Millivolts
NTU - Nephelometric turbidity unit
NA - Not analyzed
NE - Not established
NM - Not measured
pCi/L - picocuries per liter
R1 - Relative Percent Difference (RPD) value was outside control limits.
P4 - Sample field preservation does not meet EPA or method recommendations for this analysis.
D3 - Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
Spec Cord - Specific Conductance
S.U. - Standard Unit
B - Target analyte detected in method blank at or above the reporting limit. Target analyte concentration in sample is less than SOX the concentration in the method blank. Analyte concentration in sample could be due to blank contamination.
Temp - Temperature
RO - The data are unusable. The sample results are rejected due to serious deficiencies in meeting QC criteria. The analyte may or may not be present in the sample.
N2 - The lab does not hold accreditation for this parameter.
D6 - The relative percent difference (RPD) between the sample and sample duplicate exceeded laboratory control limits.
M4 - The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level. The associated Laboratory Control Spike recovery was acceptable.

Notes: System total Estimated Boron Mass Removed Since Startup:
6.4
800
System Startup occurred on March 14, 2018. Prepared by: DAA Checked by: ALA
Estimated Mass Removed (Ibs/day) = extraction well analytical result X calculated average daily flow rate (applying appropriate unit conversion)
1) Periods are divided by the closest date from beginning and end of period where water samples were taken. Therefore dates between periods may vary.
2) Total flow is the sum of weekly flow per extraction well from individual flow meters (gallons) over the sampling period. Weekly flow since system startup is reported on Table 2-1. Total Flow is the calculated difference of flow from previous sample event.
3) Calculated average daily flow rate based on total flow during period divided by number of operational days during period.
GPD - gallons per day
Ibs - pounds
Ibs/day - pounds per day
pg/L - micrograms per liter
