1.0 INTRODUCTION AND BACKGROUND
Duke Energy Progress, LLC (Duke Energy) owns and operates the H.F. Lee Energy
Complex (H.F. Lee, Lee Plant or Site) located at 1199 Black Jack Church Road,
Goldsboro, North Carolina. The property encompasses approximately 2,100 acres,
including the ash basins (171-acre inactive ash basins and 143-acre active ash basin),
cooling pond and plant operations area. A Site Location Map is included as Figure 1-1.
The Neuse River (a main stem river) flows through the property.
The Lee Plant began operation as a coal-fired electricity-generating facility in 1951.
From 1967 through 1971 four oil-fueled combustion turbine units were added. In 2000,
five simple-cycle dual fuel (oil and natural gas) units were built. The three coal-fired
units were retired in September 2012, followed by the four oil-fueled combustion
turbine units in October 2012. The new combined-cycle plant was brought on line in
2012.
1.1 Project Background
In order to satisfy requirements of the North Carolina Coal Ash Management Act (NC
CAMA), a Comprehensive Site Assessment (CSA), Corrective Action Plan (CAP) Parts 1
and 2, Interim Action Plan (IAP) and the CSA Supplemental Report (CSA SUP) were
prepared and submitted to the North Carolina Department of Environmental Quality
(DEQ). The most recent document, the CSA SUP, was submitted to DEQ on September
15, 2016.
The CAP (Parts 1 and 2) was designed to describe means to restore groundwater quality
to the level of the standards, or as close as is economically and technologically feasible
in accordance with T15A NCAC 02L.0106. Exceedances of numerical values contained
in Subchapter 2L and Appendix 1 Subchapter 02L (IMACs) at or beyond the compliance
boundary were determined to be the basis for corrective action with the exception of
parameters for which naturally occurring background concentrations are greater than
the standards.
1.1.1 Settlement Agreement
A Settlement Agreement between DEQ and Duke Energy signed on September
29, 2015, requires accelerated remediation to be implemented at sites that
demonstrate off-site groundwater impacts. Historical and CSA assessment
indicates the potential for off-site impact east of the active ash basin at H.F. Lee.
Figure 1-2 illustrates the general area to be addressed for accelerated
remediation. Arsenic and boron have been identified as constituents which
occur at levels above 2L and greater than proposed background concentrations.

H.F. Lee Energy Complex SynTerra
Page 1-2
P:\Duke Energy Progress.1026\04.LEE PLANT\22.Basis of Design Report\Design Report (30)\Report text\HF Lee Basis of Design Report.docx
Arsenic and boron impact which has the potential to migrate beyond the
compliance boundary and off site, will be the focus of the accelerated
remediation plan.
Duke Energy provided an Accelerated Remediation Summary to DEQ on
February 17, 2016 which supplemented and updated information included with
the CAP Part 2. In correspondence dated March 28, 2016, DEQ acknowledged
receipt of the Remediation Summary and requested additional information.
DEQ conditionally approved the IAP(s) in a letter dated July 22, 2016 with the
condition (among others) that a Basis of Design Report be submitted for review.
1.1.2 Interim Action Plan
The IAP, submitted to DEQ in April 2016, provided an update on planned
additional assessment and remedial activities at the site. Interim action activities
conducted in 2016 which pertain to the east side of the active ash basin are
summarized as follows:
Background monitoring wells AMW-16BC, AMW-17S and AMW-17BC
were installed north of the active basin to increase the available
background data set.
Monitoring wells AMW-18S and AMW-18BC were installed to further
delineate potential ash basin influence east of the active basin (Figure
1-2).
A pilot test was conducted in the area proposed for accelerated
remediation. The pilot test included the installation of a six inch
diameter extraction well (PTW-1) and five observation wells (PTW-2
through PTW-6). Two step drawdown tests and one 36-hour constant
rate pumping test were completed in July and August 2016.
1.1.3 Purpose of Basis of Design
The purpose of this Basis of Design Report is to provide a system layout and
sizing of system components including wells, piping, pumps, and discharge
system. It also serves to provide control system capabilities and power
requirements. This report also includes evaluation of fate and transport of
constituents, potential changes to site geochemistry as a result of remedial efforts
and evaluation of remedial alternatives. Key elements include:
Refined site conceptual model which incorporates aquifer test results

Groundwater extraction system design
Groundwater fate and transport modeling with an emphasis on boron
mobility through 2117
Geochemical modeling to address constituent mobility and potential
geochemical changes related to remediation
1.1.4 Scope and Objectives of the Interim Action
Constituents associated with coal ash pore water migration have been identified
within groundwater in the surficial flow zone at the compliance boundary east of
the active ash basin. Arsenic and boron are the primary constituents greater than
2L in groundwater. Results from monitoring wells northeast of the active basin
have not indicated arsenic and boron concentrations greater than 2L. This
indicates that constituent migration is east from the active ash basin and then
south and southeast toward the Neuse River. This is consistent with radial
groundwater flow for short distances away from the basin.
Groundwater monitoring wells indicating constituent concentrations above 2L
adjacent to the active basin are on Duke Energy property. The primary objective
of the groundwater extraction system is to accelerate the reduction of constituent
concentrations in groundwater to below 2L at and beyond the compliance
boundary and limit further migration of constituents.
1.2 Interim Action Alternative Evaluation
The CAP Part 2 and IAP evaluated groundwater extraction by (1) a network of
conventional vertical wells and, (2) an interceptor trench, as part of the remedy for the
active ash basin. The IAP proposed completion of a groundwater extraction pilot test to
determine expected flow rates and an effective radius of influence for extraction wells.
To conduct this test, United States Army Corps of Engineers (USACE) permitting for
installation of the test wells was necessary because the well locations are in potential
wetland areas. Through the permitting effort, it became clear that disturbance of
wetlands could be a significant issue in implementing the proposed interim actions.
Ground surface disturbance was determined to be less with a conventional extraction
well network than with installation of an interceptor trench. As a result, groundwater
extraction along the eastern edge of the active basin is proposed to be accomplished
with a network of conventional vertical wells. This approach was evaluated in the CAP
and determined to be feasible and effective.

H.F. Lee Energy Complex SynTerra
Page 1-4
P:\Duke Energy Progress.1026\04.LEE PLANT\22.Basis of Design Report\Design Report (30)\Report text\HF Lee Basis of Design Report.docx
In addition to less surface disturbance, this approach will also provide more operational
flexibility. With a network of wells, spatial and temporal variations in the response of
the aquifer can be addressed through operational cycling and pumping rate adjustment
to individual wells, or by adding wells.
Details of alternative remediation technologies were presented in Section 6.0 of the CAP
Part 2 (SynTerra, February 2016). The pilot test conducted at H.F. Lee in August 2016
confirmed the feasibility of implementation of extraction wells east of the active ash
basin.
1.3 Report Organization
The initial 30% submittal provides enough detail of the groundwater extraction design
to conceptualize system components, performance, and initiate evaluation of site
specific considerations. Provided herein are conceptual layout drawings, preliminary
pump and piping specifications. Findings from the aquifer pumping test which
determined potential extraction system yield and area of influence are summarized in
Section 2.3 and the pilot test report is provided as Appendix A. Sections three through
eight will continue to be developed and incorporated into 60% and 90% design
packages prior to the final (100%) submittal. Appendices including Focused Evaluation
of Alternative Remedial Technologies, Updated Groundwater Fate and Transport
Modeling Report, and Updated Geochemical Modeling Report will be provided as
interim submittals at time of completion.

2.0 REFINED SITE CONCEPTUAL MODEL
The site conceptual model (SCM) is an interpretation of processes and characteristics
associated with hydrogeologic conditions and constituent interactions at the Lee Plant
site. The purpose of the SCM is to evaluate areal distribution and flow pattern of
constituents with regard to site-specific geological/hydrogeological and geochemical
properties at the site relative to the source, potential receptors and natural control
mechanisms. The SCM was developed using data and analysis from the CSA
(SynTerra, August 2015) and was further refined in the Corrective Action Plan Part 2
(SynTerra, February 2016). This discussion incorporates additional assessment
conducted between June and August 2016.
Key components of the H.F. Lee SCM are as follows:
The ash basins, surficial deposits, the Black Creek and the Cape Fear deposits
make up distinct hydrogeologic layers at the H.F. Lee site. Unconsolidated
saprolite and/or metamorphic bedrock underlie the sedimentary deposits.
Where unconsolidated saprolitic material underlies or is laterally contiguous
with either Black Creek or Cape Fear deposits it is considered a component of
that hydrogeologic layer. Groundwater in the surficial deposits under the ash
basins flows horizontally to the east and south and discharges into the Neuse
River or Halfmile Branch.
Water within the active ash basin and inactive ash basin 1 is hydraulically higher
(upgradient) than the surrounding land surface. Pore water drains through the
underlying soil to the groundwater.
Groundwater flow is toward the Neuse River (south for the active basin, east to
southeast for the inactive basins). This flow direction is away from upgradient
receptors. The Neuse River is the hydraulic boundary for constituent migration.
Groundwater and seeps are the primary mechanisms for migration of ash-related
constituents to the environment. Both flow toward the Neuse River.
Boron and arsenic are constituents associated with the ash basins and generally
are not found at comparable levels in background wells.
Cobalt, iron, vanadium and manganese are ubiquitous in groundwater samples
including background locations. Provisional background values have been used
to interpret how much of each constituent is background or from basin influence.
Basis of Design Report – 30% Submittal November 2016
H.F. Lee Energy Complex SynTerra
Page 2-2
P:\Duke Energy Progress.1026\04.LEE PLANT\22.Basis of Design Report\Design Report (30)\Report text\HF Lee Basis of Design Report.docx
Results from sorption studies on site specific soils indicate that iron and
manganese leach from naturally occurring materials. While it is known that
these metals leach from coal ash, occurrences in background areas limit their use
as indicators of groundwater contamination.
The primary geochemical factors that affect groundwater quality in the surficial
aquifer in the vicinity of the active ash basin are variations in pH and redox
potential (Eh). In background areas upgradient from the active basin pH is
generally low (4.2 to 4.5) and Eh is high. In contrast, pH values are higher (6.0 to
6.5) and Eh values are lower in groundwater beneath and immediately
downgradient from the ash basin.
Flow rates observed during the August 2016 pumping test for the surficial
hydrogeologic unit at the east side of the active ash basin indicated higher
hydraulic conductivity (136 ft/day) than previously estimated based on slug tests
from assessment wells (geometric mean for surficial unit of 4.85 ft/day). The
duration of pumping tests is longer than slug tests and affects a larger formation
volume. Due to scale dependence, pumping tests often result in greater
estimates of hydraulic conductivity (Butler and Healey, 1998). The difference in
results illustrates the importance of pumping tests for extraction system design
purposes. Slug test results are useful data for comparison purposes but may be
heavily influenced by near-well conditions.
Field observations from well installations indicate the surficial deposits east of
the active basin are characterized by thick (15 feet or greater) layers of medium to
coarse grained sand which appear to be contiguous across the area.
Downward vertical migration of constituents is restricted due to the clay and silt
layers beneath the ash basins that act as confining layers over the deeper aquifers
in the area.
2.1 Geology and Hydrogeology
Assessment activities conducted as part of the CSA in 2015 indicate that the lithology
beneath the site generally consists of a layer of silty to clayey surficial deposits
underlain by interbedded clay and sand of the Cape Fear and Black Creek deposits.
The Cape Fear is present beneath surficial deposits in areas on the west side of the
active ash basin. The Black Creek deposits are present beneath the active basin and in
areas to the east. Field observations indicate that a confining clay layer at the top of the
Black Creek deposits is present under the active basin and to the east.
Basis of Design Report – 30% Submittal November 2016
H.F. Lee Energy Complex SynTerra
Page 2-3
P:\Duke Energy Progress.1026\04.LEE PLANT\22.Basis of Design Report\Design Report (30)\Report text\HF Lee Basis of Design Report.docx
Pertinent aspects of the hydrogeology east of the active basin are summarized as follow:
Boron and arsenic are present in the surficial hydrogeologic unit east of the
active basin at concentrations above 2L. Monitoring results from below the
underlying Black Creek confining clay do not indicate elevated boron and
arsenic concentrations.
Depth to groundwater varies from one to five feet in the area.
Surficial deposits in the area consist primarily of medium grained sand with
minor clay lenses. The surficial hydrogeologic unit thickens from the north (20
feet) to the south (40 feet) toward the Neuse River.
2.2 Summary of Baseline Site Conditions
Based on groundwater monitoring results from wells east of the active basin, arsenic
(AMW-18S, CMW-6 and CMW-6R) and boron (AMW-18S, CMW-6, CMW-6R and
CMW-5) are present at concentrations above 2L in the surficial aquifer. Constituent
concentrations at AMW-18S in July 2016 were greater than 2L standards for arsenic and
boron and were similar to June 2016 results from CMW-6R for those constituents.
Results from shallow monitoring wells to the north (AMW-17S and BGMW-10) and on
the northeastern side of the active basin (AMW-14S and AMW-15S) have not indicated
arsenic and boron exceedances. This is consistent with constituent migration towards
the CMW-6R and AMW-18S areas. Monitoring well CMW-6R is located at the
compliance boundary. Monitoring well AMW-18S is located southeast of CMW-6R, just
outside of the compliance boundary.
Preliminary groundwater fate and transport modeling included in the CAP Part 2
indicated that removing constituent mass from this area will accelerate reduction of
groundwater constituents at the compliance boundary.
2.3 Summary of Aquifer Characteristics
Aquifer testing east of the active basin consisted of two step-drawdown tests and a
pumping test in late July and early August 2016. Approximately 10,000 gallons of water
was extracted during the two step-drawdown tests. On August 2, 2016, a 36-hour
constant rate pumping test was initiated at pilot test well PTW-1. The volume of water
extracted during the 36-hour pumping test was approximately 63,500 gallons. The
extracted groundwater was pumped into the active ash basin.

H.F. Lee Energy Complex SynTerra
Page 2-4
P:\Duke Energy Progress.1026\04.LEE PLANT\22.Basis of Design Report\Design Report (30)\Report text\HF Lee Basis of Design Report.docx
Results from step-drawdown tests and pumping test indicate the following:
Average sustainable yields (over the course of the test) were at least 30 gallons
per minute.
The radius of influence is approximately 300 feet from the extraction well.
Hydraulic conductivity of approximately 136 ft/day with an assumed average
aquifer thickness of about 20 feet.
Specific yield and hydraulic conductivity are constant throughout the target area,
confirming low heterogeneity of the unconfined aquifer flow system.
Hydraulic conductivity calculated from step-drawdown and pumping tests
exceeded predicted hydraulic conductivities from well development logs.
Using graphical calculation methods and AQTESOLV Pro.4.5, the geometric
mean of the transmissivity in the surficial unit is 2,970 ft2/day. This value is
representative of medium to coarse sand.
Aquifer data in the vicinity of PTW-1 indicate conditions at this location would
support viable extraction wells under current site conditions. There was no
measurable water level drawdown of the hydrogeologic unit below the Black
Creek clay unit from pumping the surficial aquifer system.

3.0 INTERIM ACTION DESIGN CONSIDERATIONS
This section addresses the identification and evaluation of possible corrective measures
applicable to the restoration of groundwater quality in the area of interest to the east of
the active basin.
3.1 Preliminary Design Criteria and Layout
Groundwater extraction along the eastern edge of the active basin is proposed to be
accomplished with a network of conventional extraction wells. Results from aquifer
testing indicate that groundwater extraction is feasible given site conditions.
3.2 Groundwater Extraction System Design
The groundwater extraction system design is based on effective and efficient capture
and conveyance of groundwater for treatment and discharge.
Groundwater extraction was evaluated in the CAP Part 2 (SynTerra, February 2016) and
IAP as part of the remedy for the area east of the active ash basin. The IAP proposed
completion of aquifer testing to evaluate the feasibility of groundwater extraction
within this area. Results of the aquifer testing indicated groundwater extraction could
be a viable remedial alternative. Criteria for the design of groundwater extraction at the
Lee Plant include:
Installation of extraction wells with sufficient capacity to efficiently extract
groundwater and constituent mass from the surficial hydrogeologic flow system;
Well placement within the area of highest concentrations (east of the active ash
basin) as determined by extensive groundwater sampling and assessment; and
Adequate treatment of extracted groundwater to meet potential limits required
by selected discharge option.
Extracted groundwater is anticipated to be pumped to a permitted National Pollutant
Discharge Elimination System (NPDES) outfall, possibly with treatment prior to the
outfall. A conceptual layout of the remediation system is shown on Figure 1-2. The
system layout and the location of the treatment system and control panel will be further
evaluated through the 60% design submittal. The final location of the treatment system
and control panel will be coordinated with basin closure activities.
3.3 Evaluation of Alternative Technologies
Collection of groundwater can be accomplished with extraction wells or collection
trenches. For this facility, groundwater will be extracted primarily from the surficial

H.F. Lee Energy Complex SynTerra
Page 3-2
P:\Duke Energy Progress.1026\04.LEE PLANT\22.Basis of Design Report\Design Report (30)\Report text\HF Lee Basis of Design Report.docx
groundwater zone. Conventional vertical extraction wells are an effective method of
groundwater capture and will provide much more operational flexibility and less
ground disturbance than a trench. With a series of wells, spatial and temporal
variations in the response of the aquifer can be addressed through operational cycling
and pumping rate adjustment to individual wells or by adding wells. For the purpose
of accelerated groundwater remediation in the area of interest, this is the most viable
approach for ease of design and implementation.
A focused evaluation of alternative remedial technologies will be provided in
Appendix B.
3.4 Groundwater Flow Modeling
An initial Groundwater Flow and Transport Modeling Report was developed and
submitted with the CAP Part 1 on November 2, 2015. This model will be updated with
information obtained from the installation of data gap wells and the recently completed
aquifer pumping test. The updated groundwater flow model will be included in
Appendix C and prepared to inform the 60% design level.
3.4.1 Groundwater Flow Model Conceptualization Design
Discussion of Groundwater Flow Model Conceptualization Design will be
included in the final Basis of Design Report submittal.
3.4.2 Groundwater Flow Model Calibration
Discussion of Groundwater Flow Model Calibration will be included in the final
Basis of Design Report submittal.
3.5 Groundwater Extraction System Design
The groundwater extraction system design is based on effective and efficient capture
and conveyance of groundwater for treatment and discharge.
3.5.1 Current Conditions
The step-drawdown test and extended pumping test data were used to calculate
a hydraulic conductivity of approximately 136 feet per day (ft/day) with an
assumed average aquifer thickness of about 20 feet for the surficial aquifer east of
the active basin.
Aquifer data in the vicinity of PTW-1 indicate conditions at this location could
support viable extraction wells under current site conditions. Radius of
Influence (ROI) was calculated to be at least 300 feet. Average sustainable yields
were at least 30 gallons per minute (gpm). The 30 gpm flow rate yielded a 3-foot
drawdown.

3.5.2 Post-Basin Closure Conditions
Source control measures are being addressed separately but are assumed to
occur in addition to the groundwater corrective action alternatives discussed in
this submittal. The closure scenario at H.F. Lee is anticipated to involve
excavation to a lined solution. The hydraulic head currently associated with the
active basin is expected to be lowered in this closure scenario which will lessen
or remove the component of groundwater flow to the east of the basin.
3.6 Groundwater Fate and Transport Modeling
An initial Groundwater Flow and Transport Modeling Report was developed and
submitted with the CAP Part 1 on November 2, 2015. This model will be updated with
information obtained from the installation of data gap wells and the recently completed
aquifer pumping tests and groundwater analysis. The updated groundwater fate and
transport model will predict how long boron concentrations will remain above the 2L at
the offsite property boundary (compliance boundary), and at least through the year
2117. This model will be included in Appendix C and prepared to inform the 60%
design level.
3.6.1 Groundwater Fate and Transport Model Calibration
Discussion of Groundwater Fate and Transport Model Calibration will be
included in the final Basis of Design Report submittal.
3.6.2 Predictive Results
Discussion of predictive results will be included in the final Basis of Design
Report submittal.
3.6.3 Implications of Remedy on Geochemical Conditions and
Plume Stability
Implementation of the remedial strategy (groundwater extraction) is anticipated
to drive subsurface geochemical conditions toward more natural background
conditions. This is likely to result in a localized decrease in pH and increase in
Eh.
A decrease in pH will generally cause a decrease in the mobility of anions and an
increase in the mobility of cations. Anions will have a greater electrostatic
attraction and cations will have a lesser electrostatic attraction towards the
sorptive medium as mineral surfaces transition from a net negative to a net
positive surface charge. In general, the expected decrease in pH toward
background conditions may result in sustained concentrations of soluble

groundwater cationic species such as manganese, and a decrease in groundwater
concentrations of anionic species such as arsenic.
Changes in geochemistry near the ash basin as a result of groundwater
extraction, such as a return to more natural Eh-pH conditions, are not expected
to change the mobility of boron.

4.0 WELL DESIGN
The well system design is intended to provide drawdown and capture groundwater
flow to the east of the active basin.
4.1 Overview of Extraction Well Network
Based on this objective and results from the pumping test, design spacing between
extraction wells is estimated at 300 feet along the eastern edge of the basin. The
expected width of the plume at the base of the basin is approximately 2,700 feet so nine
wells are anticipated. At 30 gpm per well, the total flow rate for the proposed
extraction system would be 270 gpm. At some point greater pumping rates and
drawdown levels may be desirable so, for planning purposes, a maximum design flow
rate of 540 gpm is used.
The nine extraction wells will be located approximately adjacent to the existing
monitoring well access path to minimize disturbance of wetland areas during drilling
and installation and to provide access for operations and maintenance (O&M) of the
extraction system.
4.2 Well Construction
The extraction wells will be installed by a North Carolina licensed well driller in
accordance with North Carolina Administrative Code Title 15A, Subchapter 2C – Well
Construction Standards, Rule 108 Standards of Construction: Wells Other Than Water
Supply (15A NCAC 02C .0108). The wells are planned to be drilled using 12-inch
hollow stem auger drilling methods to allow for a 3-inch annular space around the 6-
inch casing and screen. The well casing will extend approximately one foot above
ground surface. The top of the sand pack (Gravel Pack #3) will extend to two feet above
the top of the well screen. The bentonite well seal will be at least one foot thick. Neat
cement grout with 5% bentonite will be placed to within three feet of the ground
surface. Concrete grout will be placed in the top three feet of the annular space. Due to
difficult access in some areas, well construction methods and specifications may be
modified for site specific conditions. All materials and installations will be in
accordance with 15A NCAC 02C. Groundwater modeling will aid in the determination
of minimum yield requirements to achieve the objective of accelerated remediation. A
schematic diagram of an extraction well is included as Figure 4-1.
The wells will be drilled and installed to approximate depths between 25 and 40 feet,
corresponding to the shallow aquifer thickness, to enable recovery through the entire
shallow aquifer water column. The depth of each well will correspond to the shallow
aquifer thickness at that location. The exact depths will be determined based on

observations in the field during drilling. The expected depths, based on previous
drilling data, are provided in Table 4-1. The wells will not penetrate the underlying
clay layer. The well screens will be installed near the bottom of the permeable
formation to reduce premature oxidation of iron during extraction, which could cause
extraction and pumping system fouling and loss of efficiency. Wound wire screens will
be used to reduce loss of efficiency over time and to facilitate rehabilitation if necessary.
The extraction wells will be 6-inch diameter wells with Schedule 40 PVC casings. At a
maximum depth of 40 feet, the worst case scenario collapse pressure will be 17.3 psi.

The collapse pressure for 6-inch Schedule 40 PVC is 77 psi. Six-inch diameter PVC

02C.
The well screens will be 0.010-inch (10-slot) Johnson Screen® Free-Flow® 304 stainless
steel wound wedge (or comparable) wire screens. These screens have a collapse
pressure of 87 psi.
The well screens will be 10 feet long which will provide for a minimum flow capacity of
108 gpm which is significantly greater than the maximum design flow of 60 gpm.

4.3 Groundwater Extraction Rates
Results of the pilot test activities in July and August 2016 indicate a hydraulic
conductivity of approximately 136 feet per day (ft/day) with an assumed average
aquifer thickness of about 20 feet for the surficial aquifer east of the active basin. Radius
of influence (ROI) was calculated to be at least 300 feet. Average sustainable yields
were at least 30 gallons per minute (gpm). The 30 gpm flow rate yielded a 3-foot
drawdown.

5.0 GROUNDWATER EXTRACTION SYSTEM PIPELINE AND
PUMP STATION DESIGN
5.1 Overall Pipeline Design Basis
The anticipated flow rate for the system is 270 gpm. The pipeline design basis is 540 gpm
to allow for increased pumping rates if that becomes necessary. The piping system will be
constructed either aboveground or below grade with high density polyethylene (HDPE).
Above grade installation would be adequately insulated to protect from freezing
conditions.
5.1.1 Well Pumps
The extraction wells will be equipped with a Grundfos 62S75-14 (or equal)
submersible electric pumps. Each pump will be equipped with variable frequency
drive (VFD) motor control and electrical and thermal motor protection.
Assuming similar conditions and flow rates as indicated during the pumping test,
the pumps provide 285 feet of nominal head, operate on 230 or 460 volt 3-phase
power and have a 7.5 horsepower (Hp) motor. The pump diameter is four inches
with a 2-inch discharge. At 30 gpm, the pump provides 375 feet of head and
operates at 55% efficiency. At 60 gpm, the pump provides 305 feet of head and
operates at 70% efficiency. The minimum 305 feet of head is sufficient to provide the
necessary flow rates for the system.
The expected head requirement assumes 45 feet from the well water column, 195
feet for piping losses, 30 feet for fittings loss, and an estimated 20 feet to reach
treatment system headworks.
This pump provides the greatest efficiency over the design flow rate range. Use of a
VFD will provide the capability to operate the pump at lower flow rates, if
necessary, while not significantly sacrificing efficiency or subjecting the pump to
unnecessary working pressure. The control system will include water level and
flow monitoring and feedback to the VFD and will allow for efficient, timely and
effective operation of the pumps.
5.1.2 Well Discharge Piping
It is anticipated that the well pump will discharge through a 2-inch diameter
discharge pipe to the surface. The pipe will be secured in the center of the well with
Simmons (or equal) top guides.

H.F. Lee Energy Complex SynTerra
Page 5-2
P:\Duke Energy Progress.1026\04.LEE PLANT\22.Basis of Design Report\Design Report (30)\Report text\HF Lee Basis of Design Report.docx
5.1.3 Well Head Configuration
Well boxes will be finished above or below grade and insulated to simplify O&M
(Figure 5-1 provides an above grade example). Well box piping and fittings may be
304 stainless steel to reduce risk of damage due to O&M. The piping will transition
to HDPE fusion-welded pipe.
The well seal will be Simmons Model 316 (or equal) cast solid plate, 4-bolt seal with
threaded openings for the pump power cable, level monitor and well vent.
The piping will be fitted with a Simmons Model 516SS (or equal) check valve.
Flow monitoring at the well head will be accomplished with a Sparling Tigermag EP
FM656 (or equal) electromagnetic flow meter with direct read and transmitter.
Well water level will be monitored with a Solinist Levelogger (or equal) transducer.
This feature will allow level control of the pumping system.
The piping will be fitted with a one-half inch sampling port ball valve.
The well head piping train will include a ball valve for isolation of the well head
from the header and pipe unions for maintenance access.
The well head will be enclosed within a Virtual Polymer Compounds (or equal) 6-
foot by 3-foot by 30-inch high insulated fiberglass aboveground vault with full top
access and locking cover. The vault will be attached to a poured-in-place concrete
foundation.
5.2 Extraction Well Pipeline
The extraction well header pipe will connect all of the well discharges to the treatment
system. It will be constructed of polyurethane pre-insulated 6-inch diameter DR-11 HDPE.
5.2.1 Pipe Pressure
The maximum pressure of the system will be less than 150 psi. Manufacturers’
pressure rating for DR-11 HDPE pipe is 200 psi. DR-11 pipe also meets long term
pressure performance criteria.

5.2.2 Pipe Flow
Flow velocities for the extraction well and header piping were estimated using the
Hazen Williams formula with US units. S = 𝑃𝑃𝑑𝑑𝐿𝐿=4.52 𝑄𝑄1.852 𝐶𝐶1.852 𝑑𝑑4.8704
where:
S = frictional resistance (pressure drop per foot of pipe) in psig/ft (psi gauge
pressure per foot)
Pd = pressure drop over the length of pipe in psig
L = length of pipe in feet
Q = flow, gpm
C = pipe roughness coefficient
d = inside pipe diameter, in
At the assumed header pipe operating flow rate of 270 gpm, the water velocity in
the pipe would be 3.85 feet per second (fps) and the head loss would be 0.010 feet of
water per foot of pipe length (ft/ft). At the design flow rate of 540 gpm the velocity
would be 7.71 fps and the head loss would be 0.036 ft/ft.

H.F. Lee Energy Complex SynTerra
Page 5-4
P:\Duke Energy Progress.1026\04.LEE PLANT\22.Basis of Design Report\Design Report (30)\Report text\HF Lee Basis of Design Report.docx
Piping from the well boxes to the header is anticipated to be pre-insulated 2-inch
diameter DR-11 HDPE. At the expected well line operating flow rate of 30 gpm, the
water velocity in the pipe will be 3.32 fps and the head loss will be 0.025 ft/ft. At the
design flow rate of 60 gpm the velocity will be 6.65 fps and the head loss will be
0.089 ft/ft.
These fluid velocities and head losses are within acceptable ranges given the fluid
and piping material characteristics. Installation of the pipe will be completed with
heat fused joints and insulating collars will be installed over the joints after welding
and pressure testing.
5.2.3 Pipe Insulation
To prevent freezing, the header and well extraction piping will be factory-insulated
with 1-1/2 inches thick polyurethane foam and polyurethane polymer coating.
Temperature loss over the length of the header piping under average conditions is
estimated to be 0.13 oF. This assumes a groundwater extraction temperature of 60.8
oF and the historical lowest monthly average low ambient air temperature of 34 oF.

The temperature drop using the more extreme temperature conditions and
assuming only one well is running at 30 gpm is 2.1 oF. This is also low heat loss.
Freezing should not occur under these conditions.
5.2.4 Pipe Expansion/Contraction
HDPE pipe has a thermal expansion coefficient of 67.0 × 10−6 in/in ℉. Using the
average groundwater temperature, 60.8 oF, as the starting point, the largest
dimension change would be during the record low temperature of -1 ℉. ∆𝑇𝑇=65.8 − −1 =66.8 ℉
∆𝐿𝐿=100 𝑜𝑜𝐷𝐷 × 12 𝑝𝑝𝐶𝐶𝑜𝑜𝐷𝐷× 67.0 × 10−6 in℉ in × 66.8 ℉.=5.4 𝑝𝑝𝐶𝐶
Pipe expansion loops or curvature will be included in the detailed pipe layout to
accommodate approximately 5.4 inches of expansion/contraction per 100 feet of
pipe. Due to the thermal capacity of the pipe contents and the pipe insulation, this
will be a conservative approach.

To ensure that the piping will not float due to buoyancy during flood events if the
piping system is placed aboveground, the piping will be anchored with percussion
driven or drilled helical anchors installed 5 to 10 feet deep, spaced approximately 50
feet apart, and adjacent to connection points between the header pipe and individual
well discharge pipes.
The buoyancy force will be equal to the weight of the volume of water displaced by
the piping minus the weight of the pipe material. The 6-inch pipe has a 9.75-inch

6.0 ELECTRICAL AND INSTRUMENTATION DESIGN
It is anticipated that three-phase, 460-Volt, 200-Amp electrical service will be provided to
the system from a power drop located near the system outfall. Planning at this stage
assumes the control panel for the system will be located near the proposed treatment
facility near the top of the active basin. Power to the well pumps, through the VFDs, as
well as the pumping system controls will be provided from this panel. The final location of
the system components will depend upon, and be coordinated with, basin closure
activities.
6.1 Piping and Instrumentation Diagram
The Piping and Instrumentation Diagram (P&ID) will be completed as part of the 60%
design package once the conceptual design and complete design objectives are determined.
6.2 Pump Controls
The pumps will be controlled with individual Grundfos CUE (or equal) VFDs which adjust
the power frequency to vary the motor speed to control the pumping rate. The pumping
rate can be adjusted manually or based on set points for flow rate or water level in the well
from flow or level sensor signals. The VFDs allow for soft starts of the motor and allow the
motors to operate efficiently by only drawing the necessary amperage to provide the
desired pumping rate. It is assumed that control of the system will be accomplished
through a Human Machine Interface (HMI) screen for ease of operation.
6.3 Emergency System Shutdown
The pump motors have internal shutdown systems if the motors start to draw excessive
power indicative of pump problems. The motors also have internal shutdown systems for
motor overheating. In addition to these safeguards, high pressure conditions or other
treatment system malfunctions will also trigger complete system shutdown. These
safeguards will be programmed into the pumping control system once the treatment
system design is completed.
The control system will also be equipped with an auto-dialer to notify operations staff
immediately of a system shutdown condition.

Subject: Pilot Test Report — H.F. Lee Energy Complex �Z '-.
_1 z�
A groundwater extraction pilot test was conducted at the H.F. Lee Energy Complex
(Site) located in Goldsboro, North Carolina (Figure 1). Comprehensive Site Assessment
(CSA) and historical groundwater monitoring results indicate that areas to the east and
north of the active ash basin have potential to have constituent concentrations greater
than 2L beyond the compliance and property boundaries. The pilot test was conducted
in the area east of the active ash basin to determine aquifer characteristics needed to
evaluate and design a remedial action strategy in the area (Figure 2). This report
describes the activities, methods and findings for the pilot test which included step-
drawdown and pumping test components.
1.0 SITE GEOLOGY AND HYDROGEOLOGY
The Site is located in the Atlantic Coastal plain. The Coastal Plain consists of a sequence
of stratified marine and non -marine sedimentary rocks deposited on crystalline
basement rocks. Surficial soils at the site are comprised of Quaternary alluvial deposits
associated with the adjacent Neuse River, consisting primarily of silty and clayey sands
with interbedded clay, which contain the surficial aquifer. Underlying these deposits,
at depths of around 20-feet below grade in the area of the active ash basin, is the Black
Creek Formation, the upper portion of which consists of a dark, carbonaceous -rich,
laterally continuous clay unit. The Black Creek clay unit confines the lower boundary
of the surficial aquifer. Depths to groundwater in the area of the active ash basin are
generally two to five feet below grade. Overall groundwater flow in the area of the
active ash basin is southerly toward the Neuse River.
2.0 PILOT TEST WELL INSTALLATION
Pilot test wells PTW-01 through PTW-06 were installed between July 12 and July 14,
2016 using a GeoprobeTM rig capable of both direct -push and hollow -stem auger
drilling. In order to characterize the local hydrogeology, continuous coring was
conducted at the locations of PTW-01, PTW-04, PTW-05 and PTW-06. Macro -core

samples were collected into 5-foot vinyl sleeves measuring approximately 1.5 inches in
diameter. Borings were advanced at each location until the upper portion of the Black
Creek clay unit was identified. The upper contact of the Black Creek clay varied from
approximately 19 feet below ground surface (bgs) at PTW-05 to 25 bgs at PTW-06. In
general, the soil profile encountered above the Black Creek clay unit consisted of a thin
sandy clay layer from ground surface to approximately 5 feet bgs followed by medium
to coarse grained sands to approximately 20 to 25 feet bgs. Cores were described and
photo-documented in the field. Boring logs and well construction records are provided
in Attachment 1.
Well PTW-01 was designed as a 6-inch diameter extraction well. PTW-02 through PTW-
06 were designed as 2-inch diameter observation wells. Wells PTW-01 through PTW-04
were installed with screen intervals from 10 to 20 feet bgs. Wells PTW-05 and PTW-06
were installed with screen intervals of 9 to 19 feet and 8 to 18 feet bgs, respectively.
Wells PTW-02 through PTW-06 were installed with 10-ft lengths of 0.010-inch slotted
PVC screens. Well PTW-01 was constructed with a 10-ft length of 0.010-inch slotted
stainless steel V-wire screen. As shown on Figure 1, the observation wells (PTW-02
through PTW-06) were installed at varying directions and distances which ranged from
15 feet to 150 feet from extraction well PTW-1. The extraction well permit is included
with Attachment 1.
Well development was conducted to establish communication with the surrounding
formation and until the water was generally free of turbidity. Wells were surveyed for
coordinates on the North Carolina State Plane NAD88 system and to determine top of
casing (TOC) elevations. A well construction table is provided as Table 1.
3.0 STEP DRAWDOWN TESTS
3.1 Procedure
Two step-drawdown tests were conducted, one on July 27, 2016 and one on July 28,
2016. The starting flow rate for the initial step-drawdown test was determined based on
results of slug tests from nearby assessment wells and pilot test well development
results. A Grundfos 10 Redi-Flo 3 pump with a maximum flow rate of about 15 gpm
was used for the initial step-drawdown test on July 27, 2016. Due to flow rates greater
than the predicted estimate, a second step-drawdown test was conducted on July 28,
2016 using a Grundfos 22 Redi-Flo 3 pump, which has a maximum flow rate of
approximately 34 gpm.
Prior to beginning the step-drawdown tests on July 27, 2016 and July 28, 2016, data level
loggers were installed in pilot test wells (PTW-1 and PTW-2) and water level

measurements were recorded prior to step-drawdown testing. Data loggers were
programed to collect water level measurements at a frequency of one per second.
Step-drawdown tests were conducted using pilot test well PTW-01 as the extraction
well. Water level measurements were collected prior to step-drawdown testing, during
the test and at the end of the test. Data for each step-drawdown test was recorded
using a Solinst Levelogger data logger, which was programmed to start before pumping
began. The data logger was lowered into both wells to approximately 0.5 feet from the
bottom of the well. A direct read cable was attached to the data logger installed in well
PTW-1, which allowed for real-time viewing of water level drawdown as the well was
being pumped. Once the data loggers were installed for the initial step-drawdown test,
the pump was installed into the well approximately one-foot above the data logger.
Once the water level stabilized based on the direct readings from the data logger, the
pump was started and the start time noted.
Flow rates were calculated by measuring the time to fill a 100 mL (milliliter) cylinder, a
1000 mL cylinder, or a 5 gallon bucket. Flow measurements were made several times
during a given step interval and adjustments were made to the flow valve to maintain a
steady flow rate. Periodic water level measurements were also collected to confirm the
water level data was being accurately measured and collected with the data logger. A
summary of the pumping rates and step intervals for the step-drawdown tests are
described below:

At the conclusion of each step-drawdown test, the pump was shut off and the data
logger was allowed to continue taking readings as the water level recovered in each
well. Recovery was measured for one hour and the pump and data logger were
removed from the well. Data from the data logger was downloaded to a computer for
data evaluation. The data logger was then reset to read data at one second intervals for
the next step-drawdown test.
3.2 Data Evaluation
Data from the data loggers was imported into AQTESOLV Pro.4.0. The Theis step-
drawdown solution was used to analyze the data from the step-drawdown tests. The
solution uses curve matching to determine the aquifer transmissivity (T) and storage
coefficient (S). Hydraulic conductivity was calculated using an aquifer thickness of
19.75 feet (Table 2). The outputs from the step-drawdown evaluation are included as
Attachment 2.

4.0 PUMPING TEST
4.1 Procedure
On August 2, 2016, a 36-hour constant rate pumping test was conducted at PTW-1. Data
loggers were programmed and installed 0.5 feet from the bottom of wells PTW-1, PTW-
2, PTW-3, PTW-4, PTW-5, PTW-6, CMW-6, and CMW-6R; however, level loggers did
not read throughout the pumping test. Manual water levels were collected every hour
from wells with data loggers and water levels were collected periodically during the
test from monitoring wells AMW-06BC, AMW-14S, AMW-14BC, CCR-103S, AMW-18S,
and AMW-18BC to determine radial extent of drawdown influence (Table 3, Figure 2).
Note that “PMW”, “CMW”, and “S” wells are screened in surficial deposits
and “BC” wells are screened below a laterally continuous clay unit associated with the
Black Creek deposits.
Several weather systems passed through during the pumping test. The site gauged
about 1.13’’ of rain on Tuesday, August 2nd and 0.18’’ of rain on Wednesday, August 3rd.
The Seymour Johnson Air Force Base, which is about 4.75 miles east-southeast of the
site, had an average daily barometric pressure of 29.98 to 30.06 inches of mercury.
The submersible pump in pilot test well PMW-1 was operated at a constant rate of 30
gpm for 36 hours. A flow meter was used to determine the flow rate during the pump
test and was recorded every hour. The extracted water was transferred to the active
basin. The total volume of water extracted during the 36-hour pumping test was
approximately 63,500 gallons.
4.2 Data Evaluation
Depth-to-water measurements were recorded during every hour during the 36-hour
pumping test and were analyzed using the Cooper-Jacob (1946) straight line method
(Figures 3-7) for observation wells PTW-2, PTW-3, PTW-4, and PTW-5. Head levels
from extraction well PTW-1 were imported into AQTESOLV Pro.4.0 and analyzed using
the Moench solution for unconfined aquifers (Attachment 3). CMW-6 was not analyzed
because the well was influenced by the rain events and drawdown was minimal. In
addition, the water level differences were near the error tolerance for manual level
measurements.
The Cooper-Jacob method is a solution created for confined aquifers, however since the
surficial unconfined aquifer behaves similar to a confined aquifer by the head draining
as a result of dewatering and there were no delayed yield effects observed, the confined
solutions were applied towards the end of the drawdown data.

The assumptions for applying the Cooper-Jacob method are as follows:
The aquifer is homogenous, isotropic and of uniform thickness
All layers are horizontal and extend infinitely in the radial direction
Groundwater flow is horizontal and directed radially towards the well
Pumping rate is constant
Water is released instantaneously from storage with decline of hydraulic
head
Head losses through the well screen and pump intake are negligible
The Cooper-Jacob solution is plotted on a drawdown versus log time scale to calculate
transmissivity (T):
T = 2.3𝑄𝑄4𝜋𝜋∆(ℎ𝑜𝑜−ℎ)
Note:
Q is the flow rate ∆(ℎ𝑜𝑜−ℎ) is the slope of the fitted line
By using an estimated aquifer thickness (b) based on boring logs, hydraulic conductivity
can be calculated.
K = 𝑇𝑇𝑏𝑏
The Moench solution is plotted on a log drawdown versus log time scale to calculate
transmissivity (T), specific yield (Sy), and vertical hydraulic conductivity (𝐾𝐾𝑧𝑧). The
assumptions for applying the Moench solution are as followed:
The aquifer has infinite areal extent
Aquifer is homogeneous, isotropic, unconfined and of uniform thickness
Aquifer is unsteady

The radius of influence (ROI) was determined by graphing the drawdown versus
distance plots after pumping 2170 minutes; 𝑑𝑑𝑜𝑜 was estimated to be about 300 feet
(Figure 8).
5.0 RESULTS AND RECOMMENDATIONS
Step-drawdown tests and the pumping test results conclude the surficial aquifer east of
the active basin was calculated to have a hydraulic conductivity of approximately 136
ft/day with an assumed average aquifer thickness of about 20 feet.
Aquifer data in the vicinity of PTW-1 indicate conditions at this location could support
a viable extraction well under current site conditions. A ROI calculation is shown on
Figure 8 with a result of 300 feet. In addition, there was no measurable water level
drawdown of the hydrogeologic unit below the Black Creek clay unit from pumping the
surficial aquifer system.
Using graphical calculation methods and AQTESOLV Pro.4.5, the geometric mean of the
transmissivity in the surficial unit is 2,970 𝑓𝑓𝑓𝑓2𝑑𝑑𝑑𝑑𝑑𝑑 . This value is representative of medium to
coarse sand.
Precipitation during the pump test had little effect on groundwater levels in the
surficial aquifer; however CMW-6 did see a 0.2 ft increase in head after the August 2nd
rain event which had about 1.12 inches of rain.

Recharge boundaries were not observed (positive or negative) and recovery occurred
faster than drawdown.
Results from step-drawdown tests and pumping test indicate the following:
Average sustainable yields (over the course of the test) were at least 30
gallons per minute.
The radius of influence is approximately 300 feet from the extraction well.
Specific yield and hydraulic conductivity are constant throughout the target
area, confirming low heterogeneity of the unconfined aquifer flow system.
Hydraulic conductivity calculated from step-drawdown and pumping tests
exceeded predicted hydraulic conductivities from well development logs.
SynTerra recommends initially installing a line of nine six-inch extraction wells along a
2,700 foot transect (Figure 9).
