Drinking Water Well Survey and Receptor Survey September 2014
Mayo Steam Electric Plant, Roxboro, NC SynTerra
EXECUTIVE SUMMARY
Duke Energy Progress, Inc. (Duke Energy), owns and operates the Mayo Steam Electric
Plant (Mayo Plant), located near Roxboro, in Person County, North Carolina. The Plant
is a single unit, coal-fired electricity -generating facility. Coal combustion residues
(CCR) have historically been managed in the Plant's on -site ash basin. Dry ash has been
hauled and disposed in the lined landfill located at the nearby Roxboro Steam Electric
Plant (near Semora, NC). Beginning in Fall 2014, CCR from the Plant will be managed
in a newly constructed on -site landfill.
In accordance with the requirements stipulated in Coal Ash Management Act 2014 —
North Carolina Senate Bill 729 (August, 2014), a survey was conducted to identify
drinking water supply wells and surface water bodies located downgradient of the ash
basin, 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 located within 0.5 mile of the Mayo 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 the upland
areas (the southwestern portion of the property) towards the northeast and Crutchfield
Branch.
No public or private drinking water wells, or wellhead protection areas, are located
within the potential area of interest. This finding is supported by field observations and
a review of public records. Shallow groundwater flow across the Mayo Plant facility is
from the west/southwest towards the northeast and Crutchfield Branch. Based on the
anticipated groundwater flow path, none of the wells identified in the water well
survey are located downgradient of the ash basin. Maps cross-referenced with tables
providing parcel and ownership information for the survey area are provided for
completeness, in accordance with the NORR.

1.0 INTRODUCTION
Duke Energy Progress, Inc. (Duke Energy), owns and operates the Mayo Steam Electric
Plant (Mayo Plant), located near Roxboro, in Person County, North Carolina (Figure 1).
The Plant is a single unit, coal-fired electricity -generating facility. Coal combustion
residues (CCR) have historically been managed in the Plant's on -site ash basin (Figure
2). Dry ash has been hauled and disposed in the lined landfill located at the nearby
Roxboro Steam Electric Plant (near Semora, NC). Beginning in Fall 2014, CCR from the
Plant will be managed in a newly constructed on -site landfill.
Discharge from the ash basin is permitted by the North Carolina Department of
Environment and Natural Resources (NCDENR) Division of Water Resources (DWR)
under the National Pollution Discharge Elimination System (NPDES) Permit
NC0038377.
SynTerra has completed a survey to identify water supply wells within 0.5 miles of the
Mayo Plant ash basin compliance boundary (Figure 2). The compliance boundary for
groundwater quality in relation to the ash basin 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) (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 Mayo Plant is a coal-fired electricity -generating facility located in Person County,
North Carolina, near the City of Roxboro. The location of the plant is shown on Figure
1. The Mayo Plant started operations in 1983. The plant is located on Boston Road (US
Highway 501) north of Roxboro. The northern plant property line extends to the North
Carolina/Virginia state line. The overall topography of the Plant generally slopes
toward the east (Mayo Reservoir) and northeast (Crutchfield Branch).
The Mayo Plant ash basin is approximately 153 acres in size with an earthen dike. Ash
generated from the plant's coal combustion is contained in the ash basin. The Mayo
Plant NPDES permit (NC0038377) authorizes two discharges to Mayo Lake. Outfall 001
discharges cooling tower water and circulating water system discharge water. Outfall
002 is comprised of a number of streams including internal outfall 008 (cooling tower
blowdown), internal outfall 009 (FGD blowdown), ash transport water, coal pile runoff,
and other sources including water from wastewater treatment processes. Four
stormwater outfalls are also authorized for Mayo Plant.
2.2 Description of Surrounding Properties
Properties located within a 0.5 mile radius of the Mayo Plant compliance boundary are
located in Person County, North Carolina and Halifax County, Virginia. The properties
uses include residential, commercial, industrial, and agricultural.
Figure 2 depicts the properties surrounding the Mayo Plant.

3.0 SITE GEOLOGY AND HYDROGEOLOGY
3.1 Generalized Site Hydrogeologic Conceptual Model
The Mayo Plant is situated in the eastern Piedmont of north -central North Carolina.
The Piedmont is characterized by well-rounded hills and rolling ridges cut by small
streams and drainages. Elevations in the area of the Mayo Plant range between 570 feet
above mean sea level (msl) near the Plant entrance along Boston Road to 360 feet msl in
the Crutchfield Branch stream area on the north side of the Plant.
Geologically, the Plant is located at the contact between two regional zones of
metamorphosed intrusive rocks: the Carolina Slate Belt (now referred to as Carolina
Terrane) on the east and the Charlotte Belt (or Charlotte Terrane) to the west. The
characteristics and genesis of the rocks of these regional metamorphic belts have been
the subject of intense study for many years with various approaches employed to
describe the geology in tectonic, structural, and/or litho-stratigraphic terms (Hibbard,
et. al., 2001).
Rocks of Charlotte Terrane near the Plant are characterized by strongly foliated felsic
mica gneiss and schist and metamorphosed intrusive rocks. Carolina Terrane rocks in
the vicinity of the Plant are typically felsic meta-volcanics and meta-argillites. These
conclusions are consistent with the description of the geologic nature of the area
according to the Geologic Map of North Carolina (1985). The Geologic Map of North Carolina
describes the felsic meta -volcanic rock as metamorphosed dacitic to rhyolitic flows and
tuffs, light gray to greenish gray; interbedded with mafic and intermediate volcanic
rock, meta-argillite and meta-mudstone. The felsic mica gneiss of the Charlotte Terrane
is described as being interlayered with biotite and hornblende schist.
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
saprolite or residuum. Direct observations at the Mayo Plant confirm the presence of
residuum, developed above the bedrock, which is generally 10 to 30 feet thick. The
residuum extends from the ground surface (soil zones) downward, transitioning
through a zone comprised of unconsolidated silt and sand, downward through a
transition zone of partially weathered rock in a silt/sand matrix, down to the contact
with competent bedrock.
Groundwater within the area exists under unconfined, or water table, conditions within
the residuum and/or saprolite zones and in the fractures and joints of the underlying

Survey \ Mayo \ Mayo Drinking Well Receptor Survey.docx

Drinking Water Well Survey and Receptor Survey September 2014
Mayo Steam Electric Plant, Roxboro, NC SynTerra
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/Hydrogeology
Geologically, the majority of the Mayo Plant, including the largest portion of the ash
basin and Mayo Lake are situated in the Carolina Terrane (USGS, 2007), which typically
consist of felsic meta-volcanics and meta-argillites. This description is consistent with
site -specific observations from drilling activities at the Mayo Plant, which document the
bedrock of the northwestern portion of the compliance boundary as intermediate meta -
volcanic rock of the Charlotte Terrane and the bedrock of the remainder of the site as
felsic meta-volcanics or meta-argillites of the Carolina Terrane.
Based on previous activities at the site, subsurface lithology beneath the Plant area is
comprised of tan, brown to orange sandy silt and fine to coarse sands grading into
partially weathered rock and then competent bedrock. The first occurrence of
groundwater tends to be within the partially weathered rock or competent bedrock at
depths ranging from nine to 20 feet below land surface (bls) along the downgradient
compliance boundary and greater than 30 feet bls upgradient of the ash basin.
3.3 Hydrogeologic Information for Flow Direction Determination
Shallow groundwater generally flows from local recharge zones in topographically high
areas, such as ridges, toward groundwater discharge zones, such as stream valleys.
Ridge and topographic high areas may 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 discharge for the
plant is to the north-northeast at Crutchfield Branch and, for the eastern portions of the
property, to the east and Mayo Lake. The predominant flow direction across the
property is from the topographically higher southwestern portion of the property
towards the northeast.
3.4 Groundwater Flow Direction Determination Results
Routine water level measurements and corresponding elevations from the compliance
groundwater monitoring well network indicate that groundwater flows from upland
areas (southwestern portion of the property) towards the northeast and Crutchfield
Branch. Therefore, the area between southwestern portion of the site and the
intersection with the 0.5 mile boundary to the northeast is 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 Sections (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 of the Mayo 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 Division of Water Resources (DWR)
Source Water Assessment Program (SWAP) online database for public water supply
sources to identify wells located within a 0.5 mile radius 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 any wellhead protection areas located within a 0.5 mile
radius of the compliance boundary. The NCDENR SWAP database provides detailed
assessments of all public drinking water intakes and wellhead protection areas in North
Carolina. The website address is: (httl2:Hswal2.ncwater.org/website/swap/viewer.htm).
Virginia's (VA) Department of Environmental Quality (DEQ) maintains a GIS database
called "VEGIS"
(http://www.deq.virginia.gov/ConnectWithDEQ/VEGIS/VEGISDatasets.aspx) which
includes many types of geo-spatial information. The VEGIS database was reviewed,
and it appears that it does not contain a database of water wells in the state. Virginia
DEQ personnel were contacted to verify that the state does not currently maintain a
publicly available searchable database of wells.
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

Mayo Steam Electric Plant, Roxboro, NC SynTerra
(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 water well information provided by Environmental Data
Resources, Inc. (EDR) was also conducted. The public water well information reported
for the surrounding area (North Carolina and Virginia) 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 location of a City of Roxboro water line and a fire hydrant, just south of the plant's
entrance road is based upon Person County on-line GIS information. These locations
are shown on Figure 3. The Halifax County, Virginia GIS information does not indicate
the presence of public water utilities in this part of the county.
4.4 Field Survey
During March, 2014, SynTerra personnel conducted a vehicular survey along public
roads located within 0.5 mile radius of the compliance boundary in North Carolina and
Virginia. Observations on property use, apparent proximity to available municipal
water lines and structures that may represent potential water supply wells were noted.
No wells were noted downgradient of the ash basin 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 Mayo Plant facility is from the west/southwest
towards the northeast and Crutchfield Branch (Figure 3). Based on this observation,
none of the wells identified in the water well survey are located downgradient of the
ash basin.
Water wells located upgradient of the facility 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.
TC3887559.1s 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.

should be field verified.

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.

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.
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 Oc014.
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.
Thank you for your assistance. If you have any questions, please contact Rhonda Isham, Public
Involvement Coordinator for SynTerra, at 864-527-4654.
