Cape Fear Steam Electric Plant - Moncure, NC SynTerra
EXECUTIVE SUMMARY
Duke Energy Progress, Inc. owns the Cape Fear Steam Electric Plant (Cape Fear Plant)
located on approximately 900 acres in central North Carolina near Moncure, North
Carolina. The Cape Fear Plant is located in Chatham County along the east bank of the
Cape Fear River southeast of Moncure and west of Corinth Road. The Cape Fear Plant
began operations in 1923. In the most current configuration, the Cape Fear Plant
employed two coal-fired units along with four oil -fueled combustion turbine units. Ash
generated from coal combustion was stored on -site in ash basins. Operations were
terminated at the Cape Fear Plant in October 2012 and demolition activities are
currently underway.
In accordance with the requirements stipulated in Coal Ash Management Act 2014 -
North Carolina Senate Bill 729 (August, 2014), a survey has been conducted to identify
drinking water supply wells located downgradient of the ash basins, herein referred to
as the potential area of interest. In addition, to satisfy the requirements of the Notice of
Regulatory Requirements (NORR) received by Duke on August 13, 2014, potential
water supply wells and surface water features located within 0.5 mile of the Cape Fear
Plant ash basin compliance boundary are also included.
Routine water level measurements and corresponding elevations from the groundwater
compliance monitoring well network indicate that groundwater flows from upland
areas to the east of the Plant property towards the west and west-northwest, toward
Shaddox Creek, the Haw River, and the Cape Fear River.
No public or private drinking water wells, or wellhead protection areas, are located
within the potential area of interest downgradient of the ash basins. This finding is
supported by field observations and a review of public records. Based on the
anticipated groundwater flow path, none of the wells identified in the water well
survey are located downgradient of the ash basins. The location and available
information pertaining to suspected water wells located upgradient of the facility,
within 0.5 mile of the compliance boundary, are also included in this report as required
by the NORR.

1.0 INTRODUCTION
Duke Energy Progress, Inc. (Duke Energy) owns the Cape Fear Steam Electric Plant
(Cape Fear Plant) located on approximately 900 acres in central North Carolina near
Moncure, North Carolina. The Cape Fear Plant is located in Chatham County along the
east bank of the Cape Fear River southeast of Moncure and west of Corinth Road. The
site location is shown on Figure 1.
The Cape Fear Plant began operations in 1923. In the most current configuration, the
Cape Fear Plant employed two coal-fired units along with four oil -fueled combustion
turbine units. Ash generated from coal combustion was stored on -site in ash basins.
Operations were terminated at the Cape Fear Plant in October 2012 and demolition
activities are currently underway. Wastewater discharges from the ash basins are
permitted by the North Carolina Department of Environment and Natural Resources
(NCDENR) Division of Water Resources (DWR) under National Pollution Discharge
Elimination System (NPDES) Permit NC0003433.
SynTerra has conducted a survey to identify water supply wells and surface water
features within 0.5 miles of the Cape Fear Plant ash basins compliance boundary
(Figure 2). The compliance boundary for groundwater quality in relation to the ash
management basins is defined in accordance with 15A NCAC 02L .0107(a) as being
established at either 500 feet from the waste boundary or at the property boundary,
whichever is closer to the source.
This downgradient drinking water well survey report has been prepared to meet the
requirements stipulated in Coal Ash Management Act 2014 - North Carolina Senate Bill
729 (August 2014) and the Notice of Regulatory Requirements (NORR) received by
Duke Energy on August 13, 2014.
As part of the survey, a questionnaire is being sent to owners of property within the
survey area as directed by DWR. The purpose of the questionnaire is to determine if
additional wells may be present in the area that were not observed or have not been
previously reported. The questionnaire is also designed to collect additional
information, such as well use and construction details. An addendum letter and
updated information summarizing the questionnaire findings will be submitted to the
DWR no later than November 7, 2014. The information available to date is herein
provided.

2.0 BACKGROUND
2.1 Plant and Ash Basin Description
The Cape Fear Plant began operations in 1923 and additional units were added in the
following years. In the most current configuration, the Cape Fear Plant employed two
coal-fired units along with four oil -fueled combustion turbine units. Ash generated
from coal combustion was stored on -site in ash basins. Five ash basins were used at the
Cape Fear Plant and are referenced using the date of construction: 1956, 1963, 1970,
1978, and 1985 (Figure 2).
The Plant is located off of Corinth Road, approximately three miles southeast of
Moncure, North Carolina. The Plant is situated on the east side of the Cape Fear River.
The Plant property is roughly bounded by the Cape Fear River on the west, Corinth
Road and undeveloped property to the east, Shaddox Creek and the Haw River to the
north, and undeveloped land to the south.
The 1956 ash basin is located north of the former plant, and the remaining ash basins
are located south of the plant area. The 1963 and 1970 ash basins were constructed on
the west side of the Plant property adjacent to the Cape Fear River. The 1978 ash basin
was constructed east of and abutting the 1963 and 1970 ash basins. The 1985 ash basin
was constructed east of the existing ash basins between the discharge canal and Corinth
Road. The ash basins are impounded by earthen dams. Currently, the 1956, 1963, and
1970 ash basins are covered with vegetation (both hardwood and pine trees). A small
area near the southern end of the 1970 ash basin is seasonally wet, otherwise it too has
well established vegetation. The 1978 ash basin is partially vegetation -covered (both
trees and scrub), and a portion of the southern end of the ash basin retains water. The
1985 ash basin has some grass cover and ponded water in the southwest corner of the
ash basin. Wastewater flows from the ash basins are permitted by under NPDES Permit
NC0003433.
Operations were terminated at Cape Fear Plant in October 2012 and decommissioning
activities are currently underway.
2.2 Description of Surrounding Properties
Properties within a 0.5 mile radius of the Cape Fear Plant compliance boundary are
located in southeastern Chatham County and eastern Lee County, North Carolina.
Property uses within the 0.5 mile radius include residential, recreational, industrial, and
agricultural. The Cape Fear River flows south along the western property boundary.
Figure 2 depicts the properties surrounding the Cape Fear Plant.

3.0 SITE GEOLOGY AND HYDROGEOLOGY
3.1 Generalized Site Hydrogeologic Conceptual Model
The Cape Fear Plant is situated in the Piedmont plateau region of central North
Carolina, only a few miles north and west of the contact between the Piedmont and the
North Carolina Coastal Plain. The Piedmont is characterized by well-rounded hills and
rolling ridges. Topographic elevations in the area of the Cape Fear Plant range from
approximately 150 to 200 feet above mean sea level.
Geologically, the Plant is located within the Deep River Basin (specifically the northern
portion of the Sanford Sub -basin), an irregular, half graben structural feature of Triassic
age. In the area of the Plant, the basin is surrounded by and presumably underlain by
igneous and metamorphic rocks of the Carolina Terrane (formerly Carolina Slate Belt)
rocks. Over time, continental sediments filled the basin to great thicknesses and were
subsequently cut by numerous diabase dikes. The stratigraphy of the basin, consistent
with other basins in North Carolina and Virginia, is represented by a lower sequence of
coarse -grained arkosic sandstone and conglomerate; a middle sequence of siltstone,
shale, and thin coal deposits; and an upper sequence of sandstone, mudstone, siltstone,
and conglomerate. In general, the strata of the Deep River Basin dip gently to the east
(Horton and Zullo, 1991).
Rocks of the region, except where exposed in road cuts, stream channels, and steep
hillsides, are covered with unconsolidated material formed from the in -situ chemical
and physical breakdown of the bedrock. This unconsolidated material is referred to as
residuum. Direct observations at the Cape Fear Plant confirm the presence of
residuum, developed above the sedimentary rocks of the Plant area, which is generally
15 to 30 feet thick and extends from the ground surface to the contact with rock.
Groundwater within the area exists under unconfined, or water table, conditions within
the residuum and in the fractures and joints of the underlying bedrock. The water table
and bedrock aquifers are interconnected. The residuum acts as a reservoir for water
supply to the fractures and joints in the underlying bedrock.
3.2 Site Geology/ Hyd rogeology
According to the Geologic Map of North Carolina (1985), the Cape Fear Plant is situated
within the rocks of the Pekin Formation of the Chatham Group; although, the Plant
appears to be situated near the gradational contact of the Pekin Formation with the
Cumnock Formation. The Geologic Map of North Carolina describes each of these units as
being comprised of fluvial sedimentary rocks such as conglomerate, sandstone, and
mudstone. These general observations are consistent with well lithologic logs from the

Fear\Cape Fear Drinking Water Well Survey Report.docx

Drinking Water Well And Receptor Survey September 2014
Cape Fear Steam Electric Plant - Moncure, NC SynTerra
Cape Fear Plant, which generally describe the sedimentary rocks underlying the Plant
as brown to gray mudstones and siltstones.
3.3 Hydrogeologic Information for Flow Direction Determination
As previously described, groundwater within the area exists under unconfined
conditions within the residuum and in the fractures and joints of the underlying
bedrock. Shallow groundwater generally flows from local recharge zones in
topographically high areas toward groundwater discharge zones, such as stream
valleys. Topographic high areas serve as groundwater recharge zones. Groundwater
flow patterns in recharge areas tend to develop a somewhat radial pattern from the
center of the recharge area outward toward the discharge areas and are expected to
mimic surface topography. The closest surface water bodies on the subject property
occur to the west as small, perennial and intermittent streams and creeks that flow
toward the Cape Fear River, a large regional river. The predominant flow direction for
groundwater is to the west and west-southwest.
The Cape Fear Plant is bounded on the west by the Haw and Cape Fear Rivers. The
Haw River bounds the property from its confluence with Shaddox Creek south to its
confluence with the Deep River, a distance of about 1,200 feet. The Haw River and
Deep River come together to form the Cape Fear River which extends along the western
side of the Cape Fear Plant property for about two miles (river distance). The Haw,
Deep, and Cape Fear Rivers flow south. Shaddox Creek is a perennial stream that flows
generally from northeast to the west and enters the Cape Fear Plant property in the
northeast corner of the property, eventually flowing to the Haw River. Several small
intermittent streams enter the property from the northeast and east and flow through in
the eastern and southern part of the property, eventually flowing to the "canal" and
then to an unnamed tributary to the Cape Fear River.
3.4 Groundwater Flow Direction Determination Results
The first occurrence of groundwater at the Cape Fear Plant is within the residuum at
depths ranging from approximately 10 feet to 20 feet below the ground surface. Depths
to groundwater in wells completed in the shallow bedrock are similar. Groundwater
beneath the ash basin in the residuum and shallow bedrock appears to generally flow to
the west, toward the Haw and Cape Fear rivers. The flow direction has been consistent
from year to year with minor variations.
Based on the hydrogeology of the area and site specific conditions, the Haw and Cape
Fear rivers appear to be areas of discharge for groundwater moving downgradient of
the ash basins. Therefore, the area between the ash basins and these groundwater

discharge areas would be considered the potential area of interest, with respect to
drinking water wells. The potential area of interest is shown on Figure 3.

4.0 DRINKING WATER WELL SURVEY ACTIVITIES AND FINDINGS
4.1 State Records Review
SynTerra reviewed the NCDENR Department of Environmental Health (DEH) Public
Water Supply Section's (PWSS) Public Water Supply Water Sources Geographic
Information System (GIS) point data set (pwsws.shp) and the Water Distribution Map
Service (WDMS) data set obtained from the NC OneMap GeoSpatial Portal
(http://data.nconemap.com/geoportal/catalog/main/home.page) to identify public water
supply sources and water supply lines within a 0.5 mile radius downgradient of the
Cape Fear Plant compliance boundary.
According to the NC OneMap website, the Public Water Supply Water Sources point
data was current through November 18, 2009, and that it is the most current GIS data
set of public water supply locations available from North Carolina state agencies. The
GIS point data for the public water supply wells includes, but is not limited to,
information such as public water supply (PWS) system identification numbers,
ownership information, PWS source type, well depth, and well yield. The WDMS data
set contains information on municipal water lines and other appurtenances.
On June 24, 2014, SynTerra reviewed the NCDENR DWR Source Water Assessment
Program (SWAP) online database for public water supply sources to identify wells
located within a 0.5 mile radius downgradient of the compliance boundary; to confirm
the location of wells included in the Public Water Supply Water Sources GIS point data
set, and to identify wellhead protection areas located within a 0.5 mile radius of the
compliance boundary. The NCDENR SWAP database provides detailed assessments of
public drinking water intakes and wellhead protection areas in North Carolina. The
website address is: (http://swap.ncwater.org/website/swap/viewer.htm).
4.2 Federal/Other Records Review
SynTerra reviewed the United States Geological Survey (USGS) National Hydrography
Dataset (NHD) obtained from the USGS National Map Viewer
(http://viewer.nationalmap.gov/viewer/) to identify surface waters within a 0.5 mile
radius of the compliance boundary. Hydrography data obtained from the USGS NHD
is included on Figure 3.
A review of public database information provided by Environmental Data Resources,
Inc. (EDR) was also conducted. The public water well information has been
incorporated in the summary table (Table 1) and on Figure 3. A copy of the EDR report
is included as Appendix A.

4.3 County and Utility Department Records Review
The Water Distribution Map Service (WDMS) data set obtained from the NC OneMap
GeoSpatial Portal as well as GIS websites for both Chatham County and Lee County
were reviewed for public water supply information. The presence of water lines
managed by Chatham County Utilities & Water Division were noted in the area
upgradient of Cape Fear Plant, mostly along or proximate to Corinth Road. The area of
Lee County encompassed by the 0.5 mile compliance area is located on the west side of
the Haw, Deep, and Cape Fear Rivers, beyond the area of groundwater flow moving
beneath the Cape Fear Plant. This area of Lee County is not served by municipal water
lines.
4.4 Field Survey
Between February and April 2014, SynTerra personnel conducted vehicular surveys
along public roads located within 0.5 mile of the compliance boundary. Observations
on property use, apparent proximity to available municipal water lines, structures that
may represent potential water supply wells, and surface water features were noted. No
wells were located downgradient of the ash basins compliance boundary.
A written survey questionnaire is being mailed to the owners of properties within the
survey area (Table 2). The questionnaire requests information regarding potential well
location, well use, well depth and construction, date of completion, etc. Information
reported from the questionnaire responses will be compiled and provided as an
addendum to the survey on or before November 7, 2014. An example of the survey
questionnaire is attached in Appendix B.

5.0 SUMMARY OF FINDINGS
No public or private drinking water wells or wellhead protection areas are located
within the potential area of interest (Figure 3). This finding is supported by field
observations and the results of the records review as described in Section 4.0 above.
Shallow groundwater flow across the Cape Fear Plant is from upland areas east of the
Plant towards the west and west-southwest with flow to Shaddox Creek, the Haw River
or the Cape Fear River. Based on this observation, none of the wells identified in the
water well survey are located downgradient of the ash basins.
Water wells located upgradient of the Plant and within 0.5 miles of the compliance
boundary are noted on Figure 3 in accordance with the NORR. Parcel information for
these upgradient water well locations is provided in Table 1. A questionnaire is being
sent to all the owners of property within the survey area as directed by DWR. These
property owners are summarized on Table 2. An addendum letter and updated Figure
3 summarizing the questionnaire findings will be submitted to the DWR no later than
November 7, 2014.

EDR's GeoCheck Physical Setting Source Addendum is provided to assist the environmental professional in
forming an opinion about the impact of potential contaminant migration.
Assessment of the impact of contaminant migration generally has two principal investigative components:
1. Groundwater flow direction, and
2. Groundwater flow velocity.
Groundwater flow direction may be impacted by surface topography, hydrology, hydrogeology, characteristics
of the soil, and nearby wells. Groundwater flow velocity is generally impacted by the nature of the
geologic strata.
TC3887529.1 s Page 1

GEOCHECe - PHYSICAL SETTING SOURCE SUMMARY
GROUNDWATER FLOW DIRECTION INFORMATION
Groundwater flow direction for a particular site is best determined by a qualified environmental professional
using site -specific well data. If such data is not reasonably ascertainable, it may be necessary to rely on other
sources of information, such as surface topographic information, hydrologic information, hydrogeologic data
collected on nearby properties, and regional groundwater flow information (from deep aquifers).
TOPOGRAPHIC INFORMATION
Surface topography may be indicative of the direction of surficial groundwater flow. This information can be used to
assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or,
should contamination exist on the target property, what downgradient sites might be impacted.

GEOCHECe - PHYSICAL SETTING SOURCE SUMMARY
HYDROLOGIC INFORMATION
Surface water can act as a hydrologic barrier to groundwater flow. Such hydrologic information can be used to assist
the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should
contamination exist on the target property, what downgradient sites might be impacted.
Refer to the Physical Setting Source Map following this summary for hydrologic information (major waterways
and bodies of water).

Hydrogeologic information obtained by installation of wells on a specific site can often be an indicator
of groundwater flow direction in the immediate area. Such hydrogeologic information can be used to assist the
environmental professional in forming an opinion about the impact of nearby contaminated properties or, should
contamination exist on the target property, what downgradient sites might be impacted.
AQUIFLOW®
Search Radius: 1.000 Mile.
EDR has developed the AQUIFLOW Information System to provide data on the general direction of groundwater
flow at specific points. EDR has reviewed reports submitted by environmental professionals to regulatory
authorities at select sites and has extracted the date of the report, groundwater flow direction as determined
hydrogeologically, and the depth to water table.

GEOCHECe - PHYSICAL SETTING SOURCE SUMMARY
GROUNDWATER FLOW VELOCITY INFORMATION
Groundwater flow velocity information for a particular site is best determined by a qualified environmental professional
using site specific geologic and soil strata data. If such data are not reasonably ascertainable, it may be necessary
to rely on other sources of information, including geologic age identification, rock stratigraphic unit and soil
characteristics data collected on nearby properties and regional soil information. In general, contaminant plumes
move more quickly through sandy -gravelly types of soils than silty -clayey types of soils.
GEOLOGIC INFORMATION IN GENERAL AREA OF TARGET PROPERTY
Geologic information can be used by the environmental professional in forming an opinion about the relative speed
at which contaminant migration may be occurring.

DOMINANT SOIL COMPOSITION IN GENERAL AREA OF TARGET PROPERTY
The U.S. Department of Agriculture's (USDA) Soil Conservation Service (SCS) leads the National Cooperative Soil
Survey (NCSS) and is responsible for collecting, storing, maintaining and distributing soil survey information
for privately owned lands in the United States. A soil map in a soil survey is a representation of soil patterns
in a landscape. Soil maps for STATSGO are compiled by generalizing more detailed (SSURGO) soil survey maps.
The following information is based on Soil Conservation Service STATSGO data.
Soil Component Name:
CHEWACLA
Soil Surface Texture:
silt loam
Hydrologic Group:
Class C - Slow infiltration rates. Soils with layers impeding downward
movement of water, or soils with moderately fine or fine textures.
Soil Drainage Class:
Somewhat poorly. Soils commonly have a layer with low hydraulic
conductivity, wet state high in profile, etc. Depth to water table is
1 to 3 feet.
Hydric Status: Soil meets the requirements for a hydric soil.
Corrosion Potential - Uncoated Steel: HIGH
Depth to Bedrock Min: > 60 inches
Depth to Bedrock Max: > 60 inches

Duke Energy is conducting comprehensive site assessments at operating and retired coal-fired power
plants across the state, as required by the Coal Ash Management Act of 2014 recently passed by the
North Carolina legislature. One aspect of these assessments seeks to identify private water supply
wells within a half -mile radius of the [Plant name].
You are receiving this letter because county real estate records indicate that you own property within
this half -mile radius; however, it does not mean that your property is at an environmental risk. We
need your assistance to provide information about your property for the purpose of completing the
comprehensive site assessment. #461k NW
Duke Energy has contracted with HDR Engineering, Inc. (HDR) to assist in collecting this site
information. We ask that you complete the enclosed survey and return in the enclosed, pre -paid
envelope by �2014. 1L qw1h, -
As part of Duke Energy's commitment to protecting the environment, the company regularly monitors
the groundwater around the plant and submits all results to the North Carolina Department of
Environment and Natural Resources (NCDENR), the state agency responsible for groundwater
quality. The information you provide in response to this well survey will be compiled with information
from other neighbors and forwarded to NCDENR. NCDENR will use these survey responses along
with technical information about local geology and groundwater to develop future groundwater
monitoring requirements.
