SECTION 2-SITE DESCRIPTION
1 Section 2 - Site Description
2.1 Plant Description
I
Allen is a five-unit, coal-fired electric generating plant with a capacity of 1,140 megawatts
located in Gaston County, North Carolina, near the town of Belmont. Allen is located on the
west bank of the Catawba River on Lake Wylie, as shown on Figure 1. Commercial operations
1 at Allen began in 1957.
Lake Wylie is owned by Duke Energy and operated as part of the Catawba-Wateree Project
I
Federal Energy Regulatory Commission(FERC) Project No. 2232. The reservoir is used for
hydroelectric generation, municipal water supply, and recreation. Lake Wylie has a surface
area of approximately 13,443 acres.
1 2.2 Ash Basin Description
The coal ash residue from the coal combustion process has historically been disposed of in the
I
Allen ash basin. The ash basin currently receives waste streams from the ash sluice lines
(mostly bottom ash), water treatment system wastewater, stormwater, Flue Gas Desulfurization
(FGD)system blowdown, landfill leachate, and miscellaneous cleaning and maintenance wash
I
waters. The discharge from the ash basin is permitted by the North Carolina Department of
Environment and Natural Resources(NCDENR) Department of Water Resources(DWR) under
NPDES Permit NC0004979.
IAllen has an active ash basin and an inactive ash basin. The active ash basin was
commissioned in 1973 (Duke Energy 2009)and is currently in operation. The inactive ash basin
I
is located to the north of the active ash basin and is not in operation. A large portion of the
inactive ash basin is permitted as an industrial landfill by the NCDENR Division of Waste
Management(DWM)(Permit No. 3612). See Figure 2.
IThe active ash basin is located approximately 2,500 feet to the south of the power plant on the
western side of Lake Wylie. There are two earthen dikes impounding the active ash basin; the
I
East Dike, located along the west bank of Lake Wylie and the North Dike, separating the active
and inactive ash basins. The surface area of the active ash basin is approximately 169 acres
(Duke Energy 2009)with an approximate operating pond elevation of 633.5 feet. The full pond
I
elevation of Lake Wylie is approximately 568.7 feet.
Due to the nature of Allen operations and weather, inflows to the ash basin are highly variable.
I
The inflows from the ash removal system and other plant discharges are discharged through
sluice lines into the ash basin. Prior to 2009, all of the fly ash produced was sluiced to the ash
basin. Since 2009, fly ash has been dry-handled and is infrequently sluiced to the ash basin.
I All of the bottom ash produced by the station is sluiced to the ash basin. The water level (pond
elevation)of the ash basin is maintained at approximately 633.5 feet by the use of concrete stop
logs. A 42-inch-diameter reinforced concrete pipe serves as the outlet conduit for the discharge
I
tower into Lake Wylie.

SECTION 3-SITE GEOLOGY AND HYDROGEOLOGY
' Section 3 - Site Geology and Hydrogeology
3.1 Geologic/Soil Framework
Allen and its associated ash basin system are located in the Charlotte Terrane of the Carolina
Zone (Pippin et al. 2008), or as described in the older belt terminology, the Charlotte Belt of the
Piedmont physiographic province (Piedmont)(North Carolina Geological Survey 1985). The
' Charlotte terrane is characterized by mostly felsic to mafic plutonic rocks which intrude a suite of
mainly metaigneous rocks and minor metasedimentary rocks(Pippin et al. 2008).
' The soils that overlie the bedrock in the area have generally formed from the in-place
weathering of the parent bedrock. The fractured bedrock is overlain by a mantle of
unconsolidated material known as regolith. The regolith, where present, includes the soil zone,
1 a zone of weathered, decomposed bedrock known as saprolite, and alluvium. Saprolite, the
product of chemical and mechanical weathering of the underlying bedrock, is typically
composed of silt and coarser granular material up to boulder size and may reflect the texture of
the rock from which it was formed. The weathering products of felsic rocks may be sandy-
textured and rich in quartz content while mafic rocks form a more clayey saprolite(LeGrand
2004).
Based on a review of the monitoring well installation logs provided by Duke Energy, the soils
comprising the saprolite layer on site were characterized as ranging from clayey silt to partially
' weathered rock containing quartz and potassium feldspar. Bedrock encountered on site
consists of granite and quartz diorite. See Appendix A for Boring Logs and Monitoring Well
Construction Logs.
' 3.2 Hydrogeologic Framework
The groundwater system in the Piedmont Province in most cases is comprised of two
' interconnected layers or mediums: 1) residuum/saprolite and weathered rock(regolith)
overlying, and 2)fractured crystalline bedrock(Heath 1980; Hamed and Daniel 1992). Within
the regolith layer, a thoroughly weathered and structureless material (termed residuum)occurs
near the ground surface with the degree of weathering decreasing with depth. The residuum
grades into a coarser-grained material that retains the structure of the parent bedrock and is
termed saprolite. Beneath the saprolite, partially weathered bedrock occurs with depth until
' sound bedrock is encountered. This mantle of residual soil, saprolite, and weathered rock is a
hydrogeological unit that covers and crosses various types of rock(LeGrand 1988). It provides
an intergranular medium through which the recharge and discharge of water from the underlying
fractured rock occurs. The bedrock layer consists of fractured, nonporous crystalline bedrock.
The fractures control both the hydraulic conductivity and storage capacity of the rock mass.
1 A transition zone at the base of the regolith has been interpreted to be present in many areas of
the Piedmont. The zone consists of partially weathered/fractured bedrock and lesser amounts
of saprolite that grades into bedrock and has been described as"being the most permeable part
' of the system, even slightly more permeable than the soil zone"(Harned and Daniel 1992). The
zone thins and thickens within short distances and its boundaries may be difficult to distinguish.

OGY AND HYDROGEOLOGY
It has been suggested that the zone may serve as a conduit of rapid flow and transmission of
Icontaminated water(Harned and Daniel 1992).
Piedmont topography is characterized by gently rounded sloped hills and valleys. Recharge
I typically occurs on upland areas and slopes while groundwater discharge is concentrated in
surface water bodies and lowland areas. LeGrand's(1988, 2004)conceptual model of the
groundwater setting in the Piedmont incorporates the above two medium systems into an entity
I that is useful for the description of groundwater conditions. That entity is the surface drainage
basin that contains a perennial stream or river(LeGrand 1988). Each basin is similar to
adjacent basins and the conditions are generally repetitive from basin to basin. Within a basin,
I movement of groundwater is generally restricted to the area extending from the drainage divides
to a perennial stream or river(Slope-Aquifer System; LeGrand 1988, 2004). Rarely does
groundwater move beneath a perennial stream or river to another more distant stream(LeGrand
1
2004).
Therefore, in most cases in the Piedmont, the groundwater system is a two-medium system
I (LeGrand 1988) restricted to the local drainage basin. The groundwater occurs in a system
composed of two interconnected layers: residuum/saprolite and weathered rock overlying
fractured crystalline rock separated by the transition zone. Typically, the residuum/saprolite is
I partly saturated and the water table fluctuates within it. Water movement is generally through
the fractured bedrock. The near-surface fractured crystalline rocks can form extensive aquifers.
The character of such aquifers results from the combined effects of the rock type, fracture
I system, topography, and weathering. Topography exerts an influence on both weathering and
the opening of fractures while the weathering of the crystalline rock modifies both transmissive
and storage characteristics.
IThe aquifer system in the Piedmont typically exists in an unconfined or semi-confined condition
in the bedrock zone. Under natural conditions, the general direction of groundwater flow can be
I approximated from the surface topography. Groundwater moves both vertically down through
the regolith and parallel to the bedrock surface to areas where groundwater discharges as
seepage into streams, lakes, or other surface water bodies.
IThe Allen ash basin is generally bounded to the north by the inactive ash basin (Figure 2). Lake
Wylie is located to the east of the ash basin and lies along the toe of the East Dike. To the
I south, the ash basin is generally bounded by a surface water divide located north of Reese
Wilson Road. This divide drops in elevation to the east toward Lake Wylie. The ash basin is
generally bounded to the west by a surface water divide that runs approximately along the
I alignment of South Point Road (NC 273)and upland areas east of South Point Road. The
geologicalgroundwater conditions at the site are expected to be generally consistent with the
characteristics of the conceptual groundwater model developed by LeGrand for the Piedmont
I region. The surface water divide along South Point Road likely functions as a groundwater
divide. The predominant direction of groundwater flow from the ash basin is likely in an easterly
direction, generally from South Point Road towards Lake Wylie.

SECTION 4-MONITORING PROGRAM
' Section 4 - Monitoring Program
4.1 Regulatory Requirements for Groundwater Monitoring
' The NPDES program regulates wastewater discharges to surface waters to ensure that surface
water quality standards are maintained. Allen operates under NPDES Permit NC0004979,
which authorizes discharge of cooling water(Outfall 001), operate a septic tank and ash pond
with pH adjustment and discharge domestic wastewater, stormwater runoff, ash sluice,water
treatment system wastewaters, FGD system blowdown, landfill leachate, and miscellaneous
cleaning and maintenance wash waters (Outfall 002), coal yard sump overflow(Outfall 002A)
' and power house sump overflow(Outfall 002B), miscellaneous equipment for non-contact
cooling and sealing water(Outfall 003), and miscellaneous non-contact cooling water, vehicle
washwater, and intake screen backwash (Outfall 004)to the Catawba River in accordance with
effluent limitations, monitoring requirements, and other conditions set forth in the permit.
Finally, continued operation of the FGD wet scrubber wastewater treatment system discharging
to the ash basin through internal Outfall 005. The NPDES permitting program requires that
permits be renewed every five years.
The Allen NPDES permit requires groundwater monitoring. Permit condition A(11), Attachment
XX, Version 1.1, dated June 15, 2011, lists the groundwater monitoring wells to be sampled, the
parameters and constituents to be measured and analyzed, and the requirements for sampling
frequency and results reporting. Attachment XX also provides requirements for well location
and well construction. A copy of Attachment XX is included as Appendix B.
The compliance boundary for groundwater quality for the Allen ash basin is defined in
accordance with NCAC Title 15A Chapter 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.
Sampling at the compliance groundwater wells commenced March 2011. Analytical results
have been submitted to the Department of Water Resources(DWR) before the last day of the
month following the date of sampling for all monitoring wells except AB-9S, AB-9D, AB-10S, and
' AB-10D. In the future, analytical results will be submitted to the DWR within 60 days of the date
of sampling for all monitoring wells except AB-9S, AB-9D, AB-10S, and AB-10D.
Monitoring wells AB-9S, AB-9D, AB-10S, and AB-10D are located inside of the compliance
boundary. Compliance with 2L Standards(at the compliance boundary)for AB-9S, AB-9D, AB-
IOS, and AB-10D is determined by using predictive calculations or a groundwater model. For
' these four monitoring wells, Duke Energy uses a groundwater model to predict the
concentrations at the compliance boundary. The predicted results from the groundwater model
and the analytical results for samples collected during the sampling events are to be submitted
to the DWR annually.

SECTION 4-MONITORING PROGRAM
4.2 Description of Groundwater Monitoring System
' The groundwater monitoring system for the Allen ash basin system consists of the following
monitoring wells: AB-1R, AB-4S', AB-4D, AB-9S, AB-9D, AB-10S, AB-10D, AB-11D, AB-12S,
AB-12D, AB-13S, AB-13D, and AB-14D. The compliance monitoring wells were installed in
2010 (MACTEC 2011). Well construction data is provided in Table 1 and Figure 3 provides an
example of typical construction details.
The locations for the compliance boundary monitoring wells were selected in consultation with
the DWR Aquifer Protection Section. The location of the monitoring wells, the waste boundary
' and the compliance boundary are shown on Figure 2. A summary of the monitoring well
location data is included in Appendix C.
Monitoring wells AB-4S, AB-9S, AB-10S, AB-12S, and AB-13S were installed by rotary drilling
methods using hollow stem augers, with the well screen installed above auger refusal to monitor
the shallow aquifer within the saprolite layer. These wells were installed with 15-foot screens.
The screen intervals for these wells range from 3 feet to 18 feet below ground surface (bgs)at
AB-10S to 8 feet to 23 feet bgs at AB-12S.
Monitoring wells AB-4D, AB-9D, AB-10D, AB-11D, AB-12D, AB-13D, and AB-14D were installed
by rotary drilling methods using hollow stem augers and by rock coring techniques(HQ-
diameter barrel)with the well screen installed in the uppermost region of the fractured rock
transition zone. These wells were installed with screens lengths of either 5 feet or 10 feet. The
' screen intervals for these wells range from 15 feet to 20 feet bgs at AB-11D to 110 feet to 115
feet bgs at AB-9D.
' Monitoring well AB-1 R is located to the northwest of the inactive ash basin and is considered by
Duke Energy to represent background water quality at the site. AB-1 R was installed by rotary
drilling methods using hollow stem augers, with the well screen installed above auger refusal to
monitor the shallow aquifer within the saprolite layer. AB-1 R was installed with a 20-foot-long
screen from 51 feet to 71 feet bgs.
' Monitoring wells AB-9S, AB-9D, AB-10S, and AB-10D are located down gradient from the
inactive and active ash basins. Monitoring wells AB-9S and AB-9D are located southeast of the
Retired Ash Basin Ash Landfill. Monitoring wells AB-10S and AB-10D are located to the east of
the active ash basin. AB-11D is located to the south of the active ash basin. Monitoring wells
AB-12S, AB-12D, AB-4S, AB-4D, and AB-13S, AB-13D are generally located to the west of the
active ash basin. Monitoring well AB-14D is located to the south of a portion of the inactive ash
' basin and near the western extent of the property.
With the exception of monitoring wells AB-9S, AB-9D, AB-10S, and AB-10D, the ash basin
monitoring wells were installed at or near the compliance boundary. Monitoring wells AB-9S,
' AB-9D, AB-10S, and AB-10D are located where it was not possible to access the compliance
1 ' Prior to 2011, monitoring well AB-4S was identified as AB-4. The NPDES permit condition A(11),
Attachment XX,Version 1.1,dated June 15, 2011,and the well construction records and boring logs
' presented identify monitoring well AB-4S as AB-4.

boundary. Therefore, these monitoring wells were installed inside of the 500-foot compliance
Iboundary.
Groundwater monitoring wells AB-1, AB-2, AB-2D, AB-5, AB-6A, AB-6R, and AB-8 were
installed by Duke Energy in 2004 and 2005 as part of a voluntary monitoring system.2 No
samples are currently collected from these wells under the compliance monitoring program.
I 4.3 Monitoring Frequency
The monitoring wells will be sampled three times per year in March, July, and November.
I4.4 Sample Parameters and Methods
The monitoring program consists of sampling and analysis for parameters and constituents
identified in Attachment XX of the NPDES permit(Appendix B).
IThe parameters and constituents and the analytical methods are presented in Table 2. The
analytical results will be compared to the 2L Standards.
I 4.5 Data Quality Objectives
The overall Quality Assurance(QA)objective is to ensure that reliable data of known and
I acceptable quality are provided. All measurements will be documented to yield results that are
representative of the groundwater quality. Data will be calculated and reported in units as
required by the NCDENR.
IThe analytical QA objectives for precision, accuracy, and completeness have been established
by the laboratory(s) in accordance with the Environmental Protection Agency(EPA)or other
accepted agencies for each measurement variable where possible. The objectives are outlined
in the Duke Energy Analytical Laboratory Procedures Manual and are available upon request.
I Appropriate methods have been selected to meet applicable standards for groundwater quality.
Instances may occur, however, in which the condition of the sample will not allow detection of
the desired limits for various parameters either because of matrix interference or high analyte
I concentrations requiring sample dilution. The laboratory(s)will provide sufficient documentation
with each data package to notify reviewers about any analytical problems with the data, if
needed.

SECTION 5-SAMPLING PROCEDURES
1 Section 5 - Sampling Procedures
5.1 Sampling Equipment
IDevelopment, purging, and sampling equipment shall be selected to ensure that materials are
compatible with the sample parameters and comply with state and federal regulatory
Irequirements for sampling. Positive-gas-displacement fluorocarbon resin bladder pumps are
installed in each monitoring well as dedicated purging and sampling systems.
5.1.1 Equipment Cleaning Procedures
I Dedicated sampling equipment has been installed in each monitoring well. In the event
non-dedicated equipment is used between monitoring wells, equipment will be cleaned before
use and between wells in accordance with standard EPA-approved cleaning procedures for field
Iequipment. This standard is outlined in the Standard Operating Procedures and Quality
Assurance Manual, Engineering Support Branch, EPA Region IV, February 1, 1991.
I5.2 Groundwater Sampling
5.2.1 Development of Monitoring Wells
I
All 13 monitoring wells addressed in this sampling plan have been previously developed.
If new monitoring wells are installed, they will be developed prior to initial sampling.
I Development removes silt that has settled into the bottom of the well following installation and
removes fine silt and clay particles from the well screen and sand pack surrounding the screen.
Well development is necessary to eliminate potential clogging and enhance well performance.
I Development involves removing an estimated ten or more well volumes from the well using a
positive-gas-displacement fluorocarbon resin bladder pump with up-and-down agitation to
loosen particles from the well screen. After development of a well, a true well depth is recorded
Ireferencing the top of well casing (TOC).
5.2.2 Groundwater Level and Total Depth Measurements
IWater level measurements shall be collected and recorded to determine the groundwater
elevations and groundwater flow direction and to calculate the volume of standing water in the
well. All monitoring wells have been surveyed to determine the elevation of the TOC. All depth
I
and water level measurements shall be referencing the TOC and recorded to the nearest one-
hundredth of a foot.
Water level measurements shall be made with an electronic measuring device consisting of a
Ispool of dual-conductor wire and sensor. When the sensor comes in contact with water, the
circuit is closed and a meter light and/or buzzer are attached to the spool to signal the contact.
The sensor is lowered further until it rests on the bottom of the well to determine the total depth
Iof the well referencing the TOC. The depth and water level measurements shall be used to
verify that the well has not filled with silt and to calculate the volume of water in the well.
IThe volume of well water(in gallons) is calculated using the following equation:
V= h*Tr* rz*(7.48052 gal/ft3)

I
V= volume of water in the well screen and casing (gallons)
Ih = height of standing water(feet) =total well depth -water level
r= radius of well casing (feet)
IFor example, a 2-inch-diameter casing will have a volume of 0.1631 gallons per foot.
In dedicated sampling systems, an accurate well depth is determined as indicated above after
I development of the well and prior to installation of the dedicated bladder pump. The well depth
will be re-measured anytime the dedicated sampling system is removed for repair or
replacement. The well depth, water level measurement, and calculated well volume are
Irecorded on the Groundwater Monitoring Data Sheet(Figure 4).
5.2.3 Well Purging and Sampling
I The selection of purging technique is dependent on the hydrogeologic properties of the aquifer
and hydraulic characteristics of each well. Hydraulic conductivity, water column, well volume,
screen length, and other information are evaluated to select the purging technique to acquire
I groundwater representative of the aquifer conditions. The Groundwater Monitoring Data Sheet
(Figure 4) is used to record purging methods and measurements.
A multi-parameter water quality monitoring instrument is used to measure field stabilization or
indicator parameters for determining representative groundwater during purging. These
instruments measure pH, specific conductance, temperature, dissolved oxygen (DO), and
Ioxidation-reduction potential (ORP). Instrument calibration must be performed and documented
before and after each sampling event. The pH subsystem will be calibrated with two pH
standards(pH 7.0 and 4.0) bracketing the expected groundwater pH. The specific conductance
Isubsystem will be calibrated using two standards bracketing the expected groundwater
conductivity. Calibration results will be recorded on a Field Sampling Calibration Form
(Figure 5).
IVarious well purging techniques are described below. The purging method utilized at any
particular well will be selected after considering the characteristics of the well and the purging
method(s) used during previous sampling events.
IConventional Purging
This technique entails removing one equivalent well volume and measuring the indicator
I parameters(temperature, pH, and specific conductance). When the parameters have stabilized
to within ±0.2 pH units and ±10 percent for temperature and conductivity over three to five well
volumes, representative groundwater has been achieved for sampling. It is acceptable to begin
I sampling after five complete well volumes have been removed, even when indicator parameters
have not stabilized. Groundwater is pumped into a graduated container to measure the volume
of water purged. Under normal rates of recovery, samples should be collected immediately
Iafter purging in accordance with EPA guidelines.

IAllen Steam Station Ash Basin
SECTION 5-SAMPLING PROCEDURES
For low-yield wells incapable of yielding three to five well volumes in a reasonable amount of
I time(e.g., 2 hours or less), groundwater is purged to the elevation of the pump intake while
measuring indicator parameters. Typically, low-yield wells are evacuated to dryness one time
and sampled when sufficient water level recovery occurs. Turbidity is not a required
I
stabilization parameter, but turbidity levels of 10 nephelometric turbidity units(NTU)or less
should be targeted.
I Low-Flow Purging
Low-flow purging and sampling are appropriate when the recharge rate of the well approximates
or equals the discharge rate of the pump with minimal drawdown of the water column (51 foot).
IDuring low-flow purging and sampling, groundwater is pumped into a flow-through chamber at
flow rates that minimize or stabilize water level drawdown within the well. Indicator parameters
I are measured over time (usually at 5-minute intervals). When parameters have stabilized within
±0.2 pH units and ±10 percent for temperature, conductivity, and DO; and ±10 millivolts (mV)for
ORP over three consecutive readings; representative groundwater has been achieved for
I sampling. Turbidity is not a required stabilization parameter, but turbidity levels of 10 NTU or
less should be targeted.
Modified Low-Flow Purging
This technique is considered a viable option particularly in the Piedmont region due to the likely
presence of fine-grained soils where water level drawdown cannot be stabilized while pumping.
When the well recharge rate is less than the pump discharge rate, excessive drawdown
I (>1 foot)of the water column occurs and mixes with stagnant water located above the screened
interval. One equivalent well volume is removed initially before measuring indicator parameters.
Frequently, removal of the initial well volume reduces the hydraulic head and allows for
I matching of the recharge rate with the pumping rate providing stabilization of drawdown.
Indicator parameters should be measured at 5-minute intervals using a flow-through chamber
attached to a multi-parameter water quality instrument. When parameters have stabilized to
Iwithin ±0.2 pH units and ±10 percent for temperature, conductivity, and DO; and ±10 mV for
ORP over three consecutive readings; representative groundwater has been achieved for
sampling. Turbidity is not a required stabilization parameter, but turbidity levels of 10 NTU or
Iless should be targeted.
Very Low-Yield Well Purging
I This technique provides the best option for monitoring wells that historically purge to dryness
and do not sufficiently recharge to provide adequate volume for sample collection. Wells that
yield less than 100 milliliters per minute (mUmin)frequently incur significant drawdown during
I well purging. Therefore, if the well yield is less than 100 mUmin, the volume of the pumping
system (i.e., the pump bladder,tubing, and flow-through chamber)shall be calculated and two
pumping system volumes shall be removed. Indicator parameters will be measured and
Irecorded initially, and then sample collection will begin.
5.3 Sample Collection
I Groundwater samples are collected after representative groundwater has been determined by
purging and stabilizing the indicator parameters.

SECTION 5-SAMPLING PROCEDURES
Sampling personnel wear clean, disposable, non-powdered nitrile gloves at each location.
ISamples are collected in the order of the volatilization sensitivity of the parameters:
• Metals, metalloids, and selenium
I • Sulfate, nitrate, and chloride
• Total dissolved solids
I After collection, samples will be preserved and stored according to parameter-specific methods
and delivered to the laboratory under proper Chain-of-Custody(COC) procedures. All pertinent
notations, water-level measurements, removed well volumes, and indicator parameters shall be
Idocumented on the Groundwater Monitoring Data Sheet(Figure 4).
5.4 Sample Containers, Volume, Preservation, and Holding Time
I All sample containers supplied by the laboratory for the collection of groundwater samples shall
be new and pre-cleaned as approved by EPA procedures appropriate for the parameters of
interest. Table 3 summarizes the sample containers, sample volume, preservation procedures,
I and holding times required for each type of sample and parameter. Sample containers will be
kept closed until used. All sample containers will be provided by Duke Energy or vendor
laboratories.
1 5.5 Sample Tracking
The COC procedures allow for tracing the possession and handling of individual samples from
Ithe time of field collection through laboratory analysis and report preparation. Samples shall be
pre-logged prior to sample collection. This process assigns a unique tracking number for each
sample and generates corresponding labels. An example of the COC Record is provided as
IFigure 6.
5.6 Sample Labeling
ISample containers shall be pre-labeled and organized prior to field activities as part of the
pre-sampling staging process. As samples are collected,the sampling personnel shall write the
Ifollowing information directly on the label: sampling date and time, and initials of sample
collector. This information is also recorded on the Groundwater Monitoring Data Sheet
(Figure 4) and the COC Record (Figure 6).
1 5.7 Field Documentation
Field documentation from each sampling event is recorded on the Groundwater Monitoring Data
I Sheets(Figure 4), the Field Sampling Calibration Form (Figure 5), and the COC Record (Figure
6). Additionally, a Groundwater Sampling Site Checklist(Figure 7) is completed indicating
information about the monitoring well such as proper identification (ID)tag and condition of
I protective casing and pad. Field notations shall be made during the course of the field work to
document the following information as applicable:
• Identification of well
I • Well depth
• Static water level depth and measurement technique

SECTION 5-SAMPLING PROCEDURES
5.9 Sample Custody, Shipment, and Laboratory Receipt
IFor the purpose of these procedures, a sample is considered in custody if it is:
• In actual possession of the responsible person
I • In view, after being in physical possession
• Locked or sealed in a manner so that no one can tamper with it after having been in
Iphysical custody or in a secured area restricted to authorized personnel
All samples shall be maintained in the custody of the sampling crew during the sampling event.
At the end of each sampling day and prior to the transfer of the samples off site, entries shall be
Icompleted on the COC form for all samples. Upon transfer of custody, the COC form is signed
by a sampling crew member including the date and time. If outside vendor laboratories are
utilized, samples shall be delivered to these facilities by Duke Energy personnel or courier.
IAll COC forms received by the laboratory(s) shall be signed and dated by the respective
supervising scientist(s) or their designee (at the Duke Energy lab)or the laboratory sample
Icustodian (at vendor labs) immediately following receipt by the laboratory.
The analysts at the laboratory(s) maintain a sample tracking record that will follow each sample
I through all stages of laboratory processing. The sample tracking records show the date of
sample extraction or preparation and analysis. These records are used to determine
compliance with holding time limits during lab audits and data validation.
ICustody procedures followed by Duke Energy laboratory personnel are described in detail in the
Duke Energy Laboratory Services Procedures Manual.

SECTION 6-ANALYTICAL METHODS
I Section 6 - Analytical Methods
The main analytical laboratory used in this program is the Duke Energy Laboratory Services
Laboratory: N.C. Drinking Water(NC37804)and Wastewater(#248) Certifications. The
Iorganizational structure and staff qualifications of the laboratory are discussed in its generic
Quality Assurance Program (QAP). The QAP and the Analytical Laboratory Procedures Manual
are available for review upon request.
1 Vendor laboratories that meet EPA and North Carolina certification requirements may be used
for analyses with approval by Duke Energy.

SECTION 7-INTERNAL QUALITY CONTROL CHECKS
I Section 7 - Internal Quality Control Checks
Internal laboratory quality control (QC) checks used by the laboratories are described in each
laboratory's generic QAP and procedures manual. Using the internal laboratory QC checks, the
Ilaboratories demonstrate the ability to produce acceptable results using the methods specified.
Internal quality control checks for sampling procedures and laboratory analyses will be
I conducted with each sampling event. These checks will consist of the preparation and submittal
of field blanks, trip (travel) blanks, equipment blanks and/or field replicates for analysis of all
parameters at frequencies described in the laboratory(s) procedures manuals.
IThe field QC blanks and replicates that may be included as internal QC checks are described
below. The specific type and number of blanks used may vary depending on the sampling
Ievent and will be determined by the Duke Energy field sampling personnel:
• Field Blanks: A field blank consists of a sample container filled in the field with organic-
free, deionized, or distilled water prepared and preserved in the same manner as the
Isamples. The field blank is transported to the laboratory with the samples and analyzed
along with the field samples for the constituents of interest to check for contamination
imparted to the samples by the sample container, preservative, or other exogenous
Isources. Field blanks are typically utilized for each sampling event. The field blanks are
typically analyzed for major anions, cations, and metals.
I • Trip Blanks: A trip (travel) blank is a sample container filled with organic-free water in
the laboratory that travels unopened with the sample bottles. Trip blanks are typically
utilized when sampling for volatile organic compounds. The trip blank is returned to the
I laboratory with the field samples and analyzed along with the field samples for
parameters of interest.
• Equipment Blanks: If non-dedicated equipment is used between wells, it is
I recommended that equipment blanks be collected. The field equipment is cleaned
following documented cleaning protocols. An aliquot of the final control rinse water is
passed over the cleaned equipment directly into a sample container and submitted for
I analyses.
• Field Replicates: A field replicate is a duplicate sample prepared at the sampling
locations from equal portions of all sample aliquots combined to make the sample. Both
I the field replicate and the sample are collected at the same time, in the same container
type, preserved in the same way, and analyzed by the same laboratory as a measure of
sampling and analytical precision.

' Dear Mr. Allison:
MACTEC is pleased to provide this report on behalf of our client, AE Drilling, LLC. The purpose
' of this report is to present the results of monitoring well installation and evaluation activities
conducted in November and December 2010 at the above-referenced site (Figure 1). The well
1 installation and testing was conducted in general accordance with the requirements outlined in the
Ash Basin Groundwater Monitoring Well Installation Project Work Summary (Work Summary)
1 provided by Duke Energy (Duke) and dated October 18, 2010. The following Figure, Tables and
Appendices have been included:

Table 2: Summary of Slug Test Results
Appendix A: Rock Core Photographs
1 Appendix B: Soil and Rock Boring Logs
Appendix C: NCDENR Monitoring Well Construction Records
Appendix D: Monitoring Well Development Records
1 Appendix E: Photographs of Completed Well Pairs
Appendix F: Slug Test Data
1 Four Type II groundwater monitoring well pairs and two Type II single groundwater monitoring
wells(a total of 10 wells)were installed between November 15, 2010 and December 2, 2010 at the
locations shown on Figure 1. The well locations were pre-determined by Duke and marked in the
field with wooden stakes and survey flagging. Each well pair consisted of one shallow well(using
the identifier "S") set into overburden soils and one deep well (using the identifier "D) set into

bedrock. Please note that shallow wells were not installed at two locations (MW-11 and MW-14)
I because bedrock was encountered prior to groundwater, indicating a local absence of a surficial
aquifer in these locations. In addition, MACTEC replaced one well (AB-1R), at the request of
I Duke, that had historically produced inadequate water for sampling. Standard Penetration Testing
(SPT) and split-spoon sampling was performed at five-foot intervals from the surface to bedrock
during installation of the deep well at each well pair. Soils observed in the split-spoon samples
Iwere logged in the field in accordance with the Unified Soil Classification System (ASTM
D2487/D2488). Upon auger refusal, each deep boring was extended a minimum of 10 feet into
Icompetent bedrock using HQ-sized rock core techniques.
I Rock core samples were logged in the field in accordance with the Field Guide for Rock Core
Logging and Fracture Analysis established by Midwest Geosciences. As specified in the Work
Summary, split-spoon sampling and rock coring were not performed during installation of the
I
shallow wells. Photographs of rock cores obtained during installation of the five deep wells are
included as Appendix A.
I
Shallow wells were installed using 4.25-inch ID hollow stem augers; deep wells were installed
Iusing 4.25-inch ID hollow stem augers to refusal, then HQ-sized rock core approximately 10 feet
into competent bedrock. Total depths for shallow wells ranged from 18 feet below ground surface
I (bgs) in MW-10S to 23 feet bgs in MW-12S. Total depths for bedrock wells ranged from 20 feet
bgs in MW-11D to 115 feet bgs in MW-9D. Shallow wells were constructed with 15 feet of 0.010-
slot 2-inch diameter PVC well screen and riser with well screens set so that at least 10 feet of
Iscreen is below the static water table at the time of installation. Deep wells were constructed with
5-foot well screens(except well MW-14D, in which a 10-foot screen was installed) set across low-
IRQD bedrock core intervals to facilitate maximum water flow through each well. Filter sand was
placed in the annular space between the augers and the casing from the total depth of the boring to
I at least one foot above the screen. A bentonite seal was placed on top of the filter pack and the
well was grouted to the surface. Please note that shallow well depths were typically adjusted after
I installation, but prior to placement of bentonite, to account for rise in hydraulic head observed at
each location. In these instances, additional filter sand was placed between the bottom of the
borehole and the bottom of the well. Each well was completed with a stand-up well cover that
Iextends approximately 30 inches above-grade and set into a 2-foot by 2-foot concrete pad.

I
Monitoring well ID tags were secured to the outside of the stand-up covers and well numbers were
Ietched into the wet concrete pad. Soil boring logs and well construction records for the ten
monitoring wells installed in during this work have been included as Appendix B and C,
respectively.
I
Subsequent to installation, each well was developed using a submersible or bladder pump to
remove fine-grained material. In general, each well was purged until the development water
I
appeared visually clear,at which time,water quality parameters(temperature,pH,conductivity and
I
turbidity) were recorded in 5-gallon increments until turbidity readings were less than or equal to
50 NTUs. Purge water generated during well development ranged from 10 gallons to more than
1 150 gallons and was discharged to the ground surface adjacent to each well. Please note that water
quality parameters were not recorded for well MW-11D. However, 10 gallons of water were
purged from the well during well development. Monitoring well development records are included
as Appendix D. Photographs of
ppthe completed monitoring well pairs are included as Appendix E.
PP
I
Rising head slug tests were performed on each well on December 2 and 3, 2010. Prior to the tests
an In-situ Level Troll pressure transducer and 4-foot long stainless steel slug were placed into the
I
well. The water level in the well was recorded as a"Background"test until the well recharged to
within 90% of the original measurement. Subsequent to normalization, the rising head test was
' started, the slug was removed and the change in head versus time was measured using a Rugged-
reader data logger. Slug test data was analyzed using Aqtesolv software to estimate hydraulic
conductivity in each well. A summary of slug test data is presented in Table 2. Copies of raw data
Igenerated during completion of the rising head slug tests are included in Appendix F. Electronic
slug test data is included on the attached compact disc.

the compliance of this NPDES permitted facility with the current groundwater Standards
found under 15A NCAC 2L.0200
2. WELL CONSTRUCTION. Within 120 days of permit issuance, monitoring wells, as
1
proposed on Attachment XX,shall be installed to monitor groundwater quality.
a. Monitoring wells shall be constructed in accordance with 15A NCAC 02C .0108
(Standards of Construction for Wells Other than Water Supply) and any other
I jurisdictional laws and regulations pertaining to well construction. The general
locations for all monitoring wells are indicated on Attachment XX.
b. Within 30 days of completion of well construction, a completed Well
Construction Record (Form GW-1) must be submitted for each monitoring well
to Division of Water Quality, Aquifer Protection Section, 1636 Mall Service
Center, Raleigh, NC 27699-1636.
c. The Mooresville Regional Office, telephone number (704) 663-1699, shall
approve the location of new monitoring wells prior to installation. The regional
office shall be notified at least 48 hours prior to the construction of any
I monitoring well and such notification to the Aquifer Protection Section's
regional supervisor shall be made from 8:00 a.m. until 5:00 p.m. on Monday
through Friday,excluding State Holidays.
d. Within 60 days of completion of the monitoring wells, the Permittee shall
I
submit two original copies of a site map with a scale no greater than 1-inch
equals 500 feet. At a minimum, the map shall include the following
information:
i. The location and identity of each monitoring well.
ii. The location of major components of the waste disposal system.
iii. The location of property boundaries within 500 feet of the disposal
I areas.
iv. The latitude and longitude of the established horizontal control
monument.
v. The elevation of the top of the well casing (i.e., measuring point)
relative to a common datum.
vi. The depth of water below the measuring point at the time the
measuring point is established.
vii. The location of compliance and review boundaries.
viii. The date the map is prepared and/or revised.
ix. Topographic contours in no more than ten(10)foot intervals
I
e. The above information should be overlaid on the most recent aerial photograph
taken of the site. Control monuments shall be installed in such a manner and
made of such materials that the monument will not be destroyed due to
I activities taking place on the property. The map and any supporting
documentation shall be sent to the Division of Water Quality,Aquifer Protection
Section, 1636 Mail Service Center,Raleigh,NC 27699-1636.
I f. The well(s) must be constructed by a North Carolina Certified Well Contractor,
the property owner, or the property lessee according to General Statutes 87-
98.4. If the construction is not performed by a certified well contractor, the
I property owner or lessee, provided they are a natural person, must physically
perform the actual well construction activities.

g. The monitoring wells shall be regularly maintained. Such maintenance shall
include ensuring that the well caps are rust-free and locked at all times, the
outer casing is upright and undamaged,and the well does not serve as a conduit
for contamination.
3. GROUNDWATER SAMPLING AND COMPLIANCE. Monitoring wells shall be sampled after
construction and thereafter at the frequencies and for the parameters as specified in
Attachment XX. All maps, well construction forms, well abandonment forms and
' monitoring data shall refer to the permit number and the well nomenclature as •
provided on Attachment XX.
a. Per 15A NCAC 02H .0800, a Division certified laboratory shall conduct all
laboratory analyses for the required effluent, groundwater or surface water
1 parameters.
b. The measurement of water levels shall be made prior to purging the wells. The
depth to water in each well shall be measured from the surveyed point on the
top of the casing. The measurement of pH shall be made after purging and prior
to sampling for the remaining parameters.
c. The measuring points (top of well casing) of all monitoring wells shall be
surveyed to provide the relative elevation of the measuring point for each
monitoring well. The measuring points (top of casing) of all monitoring wells
shall be surveyed relative to a common datum.
d. For monitoring wells that are not located at the Compliance Boundary, the
Compliance Monitoring Form (GW-59CCR) is not required. However, predictive
calculations or modeling shall be submitted to the Regional Office annually(i.e.
1 12 months after permit issuance) demonstrating groundwater quality standards
at the Compliance Boundary.
e. Two copies of the monitoring well sampling shall be submitted on a Compliance
Monitoring Form (GW-59CCR), and received no later than the last working day
of the month following the sampling month. Copies of the laboratory analyses
shall be kept on site, and made available upon request. The Compliance
Monitoring Form (GW-59CCR) shall include this permit number and the
appropriate well identification number. All information shall be submitted to
the following address:
1 Division of Water Quality
Information Processing Unit
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
f. For groundwater samples that exceed the ground water quality standards in
15A NCAC 02L.0202,the Regional Office shall be contacted within 30 days after
submission of the groundwater monitoring report; an evaluation may be
required to determine the Impact of the waste disposal activities. Failure to do
so may subject the permittee to a Notice of Violation,fines,and/or penalties.

4. COMPLIANCE BOUNDARY. The compliance boundary for the disposal system shall be
' specified in accordance with 15A NCAC 02L .0107(a). This disposal system was
individually permitted prior to December 30, 1983;therefore, the compliance boundary
is established at either 500 feet from the effluent disposal area, or at the property
boundary, whichever is closest to the effluent disposal area. An exceedance of
groundwater standards at or beyond the compliance boundary is subject to remediation
action according to 15A NCAC 02L.0106(c)as well as enforcement actions in accordance
with North Carolina General Statute 143-215.6A through 143-215.6C.
