Surface Water Sampling to Assess 15A NCAC 213
Compliance for Implementation of Corrective Action under 15A NCAC 02L .0106 March 2017

EXECUTIVE SUMMARY
Based on the results of groundwater assessments required by the Coal Ash
Management Act of 2014 (CAMA), Duke Energy has proposed corrective action at the
Cliffside Steam Station (Cliffside) ash basins be implemented by a combination of
installation of engineered cover systems over ash, excavation of ash, and monitored
natural attenuation (MNA). Cliffside has three ash basins and two ash storage areas:
the Unit 5 Inactive Ash Basin, the Units 1-4 Inactive Ash Basin, the Active Ash Basin,
and the Ash Storage Areas. The Broad River, the Second Broad River, the unnamed
tributary west of the Inactive Unit 5 Ash basin, and Suck Creek, located near or adjacent
to the CAMA regulated units, are classified as WS-IV (i.e., water supply) and are also
subject to Class C water quality standards. For groundwater corrective action to be
implemented under 15A North Carolina Administrative Code (NCAC) .02L .0106(1),
groundwater discharge to surface water cannot result in violations of standards for
surface waters contained in 15A NCAC 2B .0200.
In response to electronic correspondence with North Carolina Department of
Environmental Quality (NCDEQ), Duke Energy submitted a work plan dated
November 28, 2016 for surface water sampling to demonstrate compliance with 15A
NCAC 2B .0200. Subsequently, NCDEQ provided comments to that proposed plan in a
letter dated December 20, 2016. With these updates to the workplan, the Cliffside
surface water comparative assessment was scheduled to occur as soon as weather and
personnel schedules permitted.
During the week of January 30 to February 5, 2017, surface water samples were
collected from locations within the Broad River and Suck Creek where groundwater
flowing from CAMA-related source areas might cause exceedances of NCAC 2B water
quality standards. Sample collection was conducted during low or base flow conditions
to evaluate both acute and chronic water quality. Surface water samples were also
collected at background locations (upgradient of source areas) within the Broad River,
the Second Broad River, and Suck Creek. Analytical results were evaluated with
respect to NCAC 2B water quality standards and background data.
Analytical results indicate groundwater discharge from ash basins and ash storage
areas is not causing surface water constituent concentrations greater than
corresponding standards for surface water contained in 15A NCAC 2B .0200. The Jan -
Feb 2017 surface water sample results are consistent with and support previous water
quality sampling performed for the NPDES permit, CAMA Comprehensive Site
Assessment (CSA) data, and groundwater —to -surface water interaction modeling

performed to demonstrate compliance with 15A NCAC 02L .0106(1)(6). At most
locations downgradient and/or adjacent to the ash basins, constituent concentrations,
where detected, are consistent with results from background locations. At locations
SW-BRAB-2 and SW-BRAB-3, located immediately downgradient of the Active Ash
Basin outfall (NPDES Outfall 002), water hardness was measured at levels greater than
the NCAC 2B water quality standard for hardness, and appears to be associated with
wastewater discharged from NPDES Outfall 002 rather than groundwater discharges.
Based on the analytical results from this investigation, CAMA, and NPDES data,
continued evaluation of MNA for management of coal combustion residuals -affected
groundwater as a viable corrective action alternative is appropriate.

1.0 PURPOSE OF SURFACE WATER SAMPLING
Based on the results of groundwater assessments required by the Coal Ash
Management Act of 2014 (CAMA) Duke Energy has proposed corrective action at the
Cliffside Steam Station (Cliffside) ash basins be implemented by a combination of
installation of engineered cover systems over ash, excavation of ash, and monitored
natural attenuation (MNA). Regulation 15A North Carolina Administrative Code
(NCAC) 02L .0106(1)(6) requires for corrective action that is based on the natural
processes of degradation and attenuation of contaminants:
(6) that, if the contaminant plume is expected to intercept surface waters,
the groundwater discharge will not possess contaminant concentrations
that would result in violations of standards for surface waters
contained in 15A NCAC 2B .0200,
In response to electronic correspondence from the North Carolina Department of
Environmental Quality Division of Water Resources (NCDEQ), Duke Energy submitted
a work plan for surface water sampling to demonstrate compliance with this
requirement in a letter dated November 28, 2016 (Appendix A). NCDEQ provided
comments to that proposed plan in a letter dated December 20, 2016 that prescribed
specific sampling locations intended to supplement previous sampling data (Appendix
B).
The analytical results from the surface water sampling described in this report will be
used in conjunction with routine CAMA related monitoring, water quality sampling
performed for the National Pollutant Discharge Elimination System (NPDES) permit,
CAMA routine surface water monitoring, and groundwater to surface water interaction
modeling (HDR 2017), previously submitted, to demonstrate compliance with .0106
(1)(6) and to support the proposed corrective action, including MNA. The site location
map is shown on Figure 1.

2.0 SITE DESCRIPTION AND CONDITIONS
2.1 Site Description
The Cliffside site is located in the Piedmont region on the south bank of the Broad
River, in both Rutherford and Cleveland counties, Figure 1. Duke Energy Carolinas
operates Unit 5 and Unit 6 to produce electricity by combustion of coal. The site is
described in the Comprehensive Site Assessment (CSA) Report prepared by HDR
Engineering in August 18, 2015. The description information provided here is
summarized from that report. In general, site topography slopes from topographic high
areas along McGraw Road towards the Broad River and to Suck Creek. Suck Creek
transects the site, approximately from south to north discharging into the Broad River.
As shown on Figure 2, the confluence of the Second Broad River with the Broad River is
located approximately at the county line on the north bank of the Broad River. The
Broad River flows west to east and Suck Creek flows south to north.
Cliffside has three ash basins and two ash storage areas. The Unit 5 Inactive Ash Basin,
the Unit 1-4 Inactive Ash Basin, the Active Ash Basin, and the Ash Storage Areas are
located along the south bank of the Broad River. Suck Creek runs along the western
side of the Active Ash Basin. The groundwater flow and 2L exceedances from the ash
basins were evaluated by the CSA, the Corrective Action Plan Part 1 (CAP Part 1), and
the Corrective Action Plan Part 2 (CAP Part 2) (HDR 2015, HDR 2016). These reports
depict groundwater flow from the ash basins at Cliffside to adjacent surface water
bodies. The adjacent surface water bodies and the surface water classifications are
listed below:
Adjacent Surface Water Body
Surface Water Classification
(15A NCAC 2B .0300)
Broad River
WS-IV
Suck Creek
WS-IV
Western Creek
WS-IV
Notes:
1) WS-IV waters are also subject to Class C water quality standards
2) The surface water classification of the Second Broad River is WS-IV. The
Second Broad River flows from the north to the confluence with the Broad
River. The Second Broad River would not receive groundwater discharge
from ash source areas.

2.2 Site Conditions
The site is an actively operating electric generation facility. As described in the CSA,
the Unit 5 Inactive Ash Basin and the Units 1-4 Inactive Ash Basin contain ash but are
no longer actively in service. The excavation of ash from the Unit 1-4 Inactive Basin
began in 2015 and is still occurring. The Active Ash Basin continues to receive ash from
the operation of Unit 5. Ash produced by Unit 6 is dry handled and disposed of in the
on -site lined NCDEQ permitted landfill.
The extent of groundwater exceedances at the site was presented in the CSA, with
subsequent analytical results presented in the CAP Part 1, CAP Part 2, and CSA
Supplement 2. Analytical results from on -going monitoring are submitted to NCDEQ
monthly.
2.3 CAMA Monitoring
NCDEQ provided requirements to conduct interim monitoring at the Duke Energy coal
ash facilities in a letter dated December 21, 2016. Beginning in the second quarter 2017,
this interim montoring requires quarterly monitoring of groundwater, surface water,
and seep (area -of -wetness) locations for the same constituents and parmeters required
for the CSA monitoring. The monitoring results are submitted to NCDEQ monthly
with a report to be submitted by April 30th of 2018. The proposed interim monitoring
consists of sampling the following locations: 195 monitoring wells, 8 surface water
sample locations, and 47 seep locations. On February 2, 2017, Duke Energy provided a
response to NCDEQ's December 21, 2016 letter requesting modifications to the
proposed list of sampling locations. The list of proposed interim monitoring locations
and excerpts from both NCDEQ's December 21, 2016 letter and Duke Energy's February
2, 2017 letter are provided in Appendix C.
2.4 NPDES Monitoring
Surface water discharges from the station are permitted by the NCDEQ under the
National Pollutant Discharge Elimination System (NPDES) Permit NC0005088. The
permit describes both the Broad River and Suck Creek as receiving waters.
In addition to monitoring at outfall locations, the draft NPDES permit, dated September
13, 2016, contains the requirements to monitor constituents at seep locations and to
conduct instream monitoring.
The draft NPDES permit states that the facility identified 35 seeps in areas surrounding
the active and inactive ash basins. Based on low concentrations of constituents
associated with coal ash and/or the absence of a discharge to "Waters of the State",
fourteen (14) of the seep locations do not require coverage under the permit and are not

considered as point -source discharges under the Clean Water Act. Eighteen (18) of the
remaining twenty-one (21) seeps were identified as effluent channels and are identified
in the draft permit as seep outfalls. The remaining three seep outfalls contribute to flow
toward Seep Outfall 102. Duke is required to sample these outfalls for the parameters
listed in the permit monthly for 1 year after the effective date of the permit and then
quarterly.
Section A.(49.) of the draft permit also requires that within 180 days after the effective
date of the permit, instream sampling be conducted to demonstrate that the water
quality standards in the receiving stream are not contravened. The draft permit
contains the following instream monitoring requirements:
A. (30.) INSTREAM MONITORING
The facility shall conduct semiannual instream monitoring at the following
locations:
1) Broad River —upstream at Alternate Route 221 and downstream at Hwy 150.
2) Suck Creek - at least 100 feet upstream from outfall 132 and downstream before
the confluence with the Broad River.
The draft permit requires that sampling shall be conducted for arsenic, selenium,
mercury (method 1631E), chromium, lead, cadmium, copper, zinc, bromide, hardness,
and total dissolved solids (TDS). The approximate location of the instream monitoring
stations are shown on Figure 2. The Broad River upstream location corresponds
approximately with sample location SW-9, and the Suck Creek locations correspond
approximately with SW-SC-1 (at least 100 feet upstream of outfall 132) and SW-4
(downstream before the confluence with the Broad River). The Broad River
downstream location is located downstream of the eastern extent of the area shown on
Figure 2.

3.0 SAMPLING LOCATIONS AND PROCEDURES
3.1 Sampling Locations
Figure 2 shows the site layout and sample locations for CAMA surface water
monitoring points, areas of wetness (AOWs), groundwater monitoring wells, draft
NPDES outfalls, including effluent channels, and the locations of the surface water
samples collected in the January -February 2017 surface water sampling event. The
Jan/Feb 2017 surface water sample locations were prescribed by NCDEQ in a December
20, 2016 letter to Duke Energy (Appendix B) to fill data gaps between previous CAMA
and NPDES surface water monitoring locations and to further evaluate the use of MNA
for groundwater at the site.
Minor modifications to the prescribed surface water sampling locations were made
based on access constraints and were approved by NCDEQ. A summary of the Jan/Feb
2017 surface water assessment areas is as follows:
07 Background (3 locations) — SW-BRBG (Broad River), SW-02 (Suck Creek), SW-
SBRBG (Second Broad River)
47 Unit 5 Inactive Ash Basin (2 locations) — SW-WCU5-1 (Western Creek), SW-
BRU5-1 (Broad River)
Units 1-4 Inactive Ash Basin (3 locations) — SW-BRU14-1 (Broad River), SW-
BRU14-2 (Broad River), SW-BRU14-3 (Broad River)
07 Western Ash Storage Area (2 Locations) — SW-SC-7 (Suck Creek) and SW-BRAB-
1 (Broad River)
-0 Main Dam of Active Ash Basin (2 locations) — SW-BRAB-2 (Broad River) and SW-
BRAB-3 (Broad River)
10 Western Dammed Area of Active Ash Basin (3 locations) — SW-SC-4 (Suck
Creek), SW-SC-5 (Suck Creek), and SW-SC-6 (Suck Creek)
y Southwestern Area of Active Ash Basin (3 locations) — SW-SC-1 (Suck Creek),
SW-SC-2 (Suck Creek), SW-SC-3 (Suck Creek)
Note the term "Western Creek" is a reference to the otherwise unnamed tributary that is
located west of the Unit 5 Inactive Ash Basin.

3.2 Analytical Parameters and Methods
For the special Jan/Feb 2017 sampling event, surface water samples were collected and
analyzed for the parameters listed in Table 1. Samples were submitted to Pace
Analytical Laboratory, LLC in Asheville, North Carolina. Table 1 of the November 28,
2016 workplan provided by Duke Energy to NCDEQ (Appendix A) presented the
proposed analytical parameters, analytical methods, and corresponding reporting
limits.
Laboratory method detection limits for dissolved silver (0.07 micrograms per liter
(µg/L)) using USEPA Method 200.8 are greater than applicable NCAC 2B chronic
criteria for aquatic life (0.06 µg/L). The laboratory reporting limit for silver is 0.5 µg/L.
This is an instance where the surface water criteria are below achievable reporting
limits. However, as discussed further in Section 4, there were no exceedances of other
metals in any samples collected as part of this investigation. Therefore, silver
concentrations in these samples are likely less than 0.06 µg/L.
3.3 Sample Collection Methods
Samples collected from the Broad River, the Second Broad River, and Suck Creek were
collected by direct grab from within two feet or less from the edge of the stream/river
bank. At locations where the banks were excessively steep or undercut to preclude
walking to the water's edge, sampling equipment (e.g., dipper, peristaltic pump) was
used to collect the samples. Sample collection was conducted during low or base flow
conditions after a period of five days with no measurable precipitation, as well as no
measureable precipitation during the four day sampling event. A summary of rainfall
totals recorded at the site from January 22 to February 5, 2017, which brackets the
sampling event, is presented as Table 2. Summaries of the Broad River stage recorded
at the nearest United States Geological Survey (USGS) river gaging station, located near
Boiling Springs, NC is included in Appendix D.
Typically, surface water sampling for compliance with 15A NCAC 02B allows for
mixing with the receiving water body. However, in order to assess potential inputs
from groundwater discharges to surface water bodies and "to avoid lateral mixing that
can dilute the sample", NCDEQ requested "near bank" sample collection (Appendix B).
Locations were sampled at a frequency to allow an assessment with 15A NCAC 02B
water quality standards. Rule 15A NCAC 02B .0211 (11) (e) states: "Compliance with
acute instream metals standards shall only be evaluated using an average of two or
more samples collected within one hour. Compliance with chronic instream metals
standards shall only be evaluated using an average of a minimum of four samples taken

on consecutive days, or as a 96-hour average". At each location, two samples were
collected within one hour and the remaining two samples were collected within the
following 95 hours. Samples were collected from the same physical locations during
each of the four sampling events. Flagging tape and stakes were placed to mark the
sampling locations, and in some cases, mark the best route to the sampling location in
case additional sampling is needed. Downstream locations were sampled prior to
upstream locations to minimize sediment disturbance and turbidity in the sample.
Sample aliquots for sulfide were inadvertently not collected on the first day of sampling
(January 30, 2017). Samples were collected at those locations for sulfide only on the
following day (January 31, 2017).

4.0 RESULTS
Surface water sample analytical results are summarized in Table 3, including historic
sampling results for parameters that were analyzed as part of this assessment. Table 4
presents a summary of the Jan/Feb 2017 surface water sample analytical results for non -
hardness dependent constituents and compares those results with established NCAC 2B
values. Table 5 presents a summary of the Jan/Feb 2017 surface water sample analytical
results for hardness -dependent dissolved metals and compares those results with
established NCAC 2B values. Comparative criteria for hardness -dependent dissolved
metals at locations where hardness values were greater than 25 milligrams per liter
(mg/L) are based on actual in -stream hardness values using calculations specified in
Table A of 15A NCAC 02B .0211 (11) (c). For applicable constituents, the average of the
first two sample sets was used for acute comparative assessment; the average of four
sample sets was used for chronic comparative assessment. An evaluation of
constituents that exceed 2B values for metals need also consider 15A NCAC 02B .0211
(11)(f) which states the following:
Metals criteria shall be used for proactive environmental management. An
instream exceedence of the numeric criterion for metals shall not be considered to
have caused an adverse impact to the instream aquatic community without
biological confirmation and a comparison of all available monitoring data and
applicable water quality standards. This weight of evidence evaluation shall take
into account data quality and the overall confidence in how representative the
sampling is of conditions in the waterbody segment before an assessment of
aquatic life use attainment, or non -attainment, shall be made by the Division.
Recognizing the synergistic and antagonistic complexities of other water quality
variables on the actual toxicity of metals, with the exception of mercury and
selenium, biological monitoring will be used to validate, by direct measurement,
whether or not the aquatic life use is supported,
Table 6 presents a summary of surface water sample analytical results for constituents

Water Quality Criteria for Protection of Aquatic Life and/or Water Supply, for

provided by Duke Energy to NCDEQ. The most recent data from December 2016 was
reported on February 15, 2017, and is evaluated herein (NCDEQ 2017).
Boron is an indicator of potential influence from the ash basins on water quality.
Therefore, the most recently available boron concentrations in surface water,
groundwater, and AOWs are presented on Figures 3-9, as requested by NCDEQ. Boron
concentrations presented on Figures 3-9 for groundwater and AOWs are summarized
on Table 7. Surface water sample results for boron obtained during Jan/Feb 2017 are
included on Figures 3-9 as a range, showing the highest and lowest concentration of the
four samples collected within the 96-hour period.
4.1 Background Surface Water Quality
Surface water samples were collected at background locations (upgradient of source
areas) within the Broad River, the Second Broad River, and Suck Creek. Background
surface water sampling locations are shown on Figure 2. Results of the analytical
results for background sampling are discussed below with respect to a comparison to
NCAC 2B values.
4.1.1 Broad River Background
Analytical results from sampling in the Broad River at SW-BRBG upgradient of
the ash basins indicate constituent concentrations less than applicable 2B criteria.
These results are also consistent with historical sample results collected from the
nearby location SW-09, and those results are less than applicable 2B criteria.
4.1.2 Second Broad River Background
Analytical results from sampling in the Second Broad River at SW-SBRBG
upgradient of the ash basins and prior to its confluence with the Broad River
indicate constituent concentrations less than applicable 2B criteria.
4.1.3 Suck Creek Background
Analytical results from sampling in Suck Creek at SW-2, upgradient of the ash
basins and prior to its confluence with the Broad River, indicate constituent
concentrations less than applicable 2B criteria. These results are also consistent
with historical sample results collected from SW-02, and those results are less
than applicable 2B criteria.
4.2 Surface Water Quality Adjacent to and/or Downgradient of Ash
Basins and Ash Storage Areas
Surface water samples were collected within the Western Creek, Broad River, and Suck
Creek at locations adjacent to and/or downgradient of the CAMA ash management

areas. Sampling locations are shown on Figure 2. As requested by NCDEQ, Figures 4
through 9 present six specific areas of interest across the site at a larger scale. Figures 4
through 9 also present recent boron results. Analytical results for sampling
downgradient and/or adjacent to the CAMA management areas are discussed below
with respect to a comparison to NCAC 2B values and are grouped by specific areas of
interest. For reference, the discussion below also includes a preliminary comparison of
results to background samples that correspond with the water body from which the
samples were collected, such as the Broad River or Suck Creek. However, the scope of
this surface water comparative assessment did not include a thorough background
evaluation and statistical development for comparison. Although background samples
may be used for preliminary comparison to samples collected downstream, there is
potential for water character to be influenced by constituent loading at areas between
the background locations and downstream sample locations.
4.2.1 Unit 5 Inactive Ash Basin
Surface water samples collected downgradient of the Inactive Unit 5 Ash Basin
include one location from within the Western Creek and one location within the
Broad River downgradient of its confluence with the Western Creek as shown on
Figures 2, 3, and 4. Figure 4 presents the Unit 5 Inactive ash basin area of
interest and includes the headwaters of the Western Creek and its confluence
with the Broad River, the Broad River as it passes the Unit 5 Inactive Ash Basin,
the extents of the Unit 5 Inactive Ash Basin, the Cliffside CCP Landfill, and the
Broad River background sampling location (SW-BRBG). Since the headwaters
for the Western Creek emerge from an area adjacent to the Unit 5 Inactive Ash
Basin, a valid background sample from the Western Creek may not be
applicable.
Western Creek
Analytical results from sampling in the Western Creek at SW-WCU5-1
downgradient of the Unit 5 Inactive Ash Basin indicate constituent
concentrations less than applicable 2B criteria.
Broad River
Analytical results from sampling in the Broad River at SW-BRU5-1 downgradient
of the Unit 5 Inactive Ash Basin indicate constituent concentrations less than
applicable 2B criteria. Constituent concentrations at SW-BRU5-1 were similar to
those detected in background sample SW-BRBG.

4.2.2 Units 1-4 Inactive Ash Basin
Surface water samples collected downgradient of the Units 1-4 Inactive Ash
Basin included three locations within the Broad River and are shown on Figures
2, 3, and 5. Figure 5 presents the Units 1-4 Inactive Ash Basin area of interest and
includes the confluence of Suck Creek and the Broad River, the Broad River as it
passes the Units 1-4 Inactive Ash Basin, and the extents of the Units 1-4 Inactive
Ash Basin.
Analytical results from sampling in the Broad River at SW-BRU14-1, SW-BRU14-
2, and SW-BRU14-3 downgradient of the Units 1-4 Inactive Ash Basin indicate
constituent concentrations less than applicable 2B criteria. Constituent
concentrations at these three locations were similar to those detected in
background samples SW-BRBG and SW-SBRBG.
4.2.3 Ash Storage Area
Surface water samples collected downgradient of the western Ash Storage Area
include one location within Suck Creek and one location within the Broad River,
downstream of its confluence with Suck Creek, as shown on Figures 2, 3, and 6.
Figure 6 presents the western Ash Storage area of interest and includes the
confluence of Suck Creek with the Broad River, the Broad River as it passes the
western Ash Storage Area, portions of the Active Ash Basin, and the extents of
the western Ash Storage Area.
Suck Creek
Analytical results from sampling in Suck Creek at location SW-SC-7,
downgradient of the western Ash Storage Area, indicate constituent
concentrations less than applicable 2B criteria. Constituent concentrations at SW-
SC-7 were similar to those detected in background sample SW-2. These results
are also consistent with historical sample results collected from SW-04, located
downstream of SW-SC-7, and those results are less than applicable 2B criteria.
Broad River
Analytical results from sampling in the Broad River at SW-BRAB-1,
downgradient of the western Ash Storage Area and non -engineered discharge
location S-4/Outfall 104, indicate that constituent concentrations are within the
acceptable range of applicable 2B criteria, with the exception of dissolved oxygen
recorded in the field during sample collection on February 1, 2017. The
dissolved oxygen concentrations measured that day are likely due to field
instrumentation error, as previous dissolved oxygen concentrations at SW-
BRAB-1 and other nearby locations in the Broad River were recorded to be at

concentrations greater than the 2B minimum of 5 mg/L. Other constituent
concentrations at SW-BRAB-1 were similar to those detected in background
samples SW-BRBG and SW-SBRBG, although several constituent concentrations
were slightly greater than background, notably during the initial acute sampling
event. During that initial event, the turbidity was slightly elevated, which may
have influenced the results. However, some indicator parameters such as boron,
chloride, and sulfate that may not be related to turbidity were also greater than
background indicating the western Ash Storage Area may have some influence
on surface water quality in the Broad River at this location.
4.2.4 Main Dam of Active Ash Basin
Surface water samples collected downgradient of the main dam of the Active
Ash Basin include two locations from within the Broad River as shown on Figure
2, 3, and 7. Figure 7 presents the main dam of the Active Ash Basin area of
interest and includes the confluence of Suck Creek with the Broad River, the
Broad River as it passes the Western Ash Storage Area, portions of the Active
Ash Basin and the extents of the Western Ash Storage Area. Figure 7 also
presents discrete hardness concentrations and hardness concentrations averaged
from the four samples collected during the Jan/Feb 2017 sampling event at SW-
BRAB-2 and SW-BRAB-3.
Analytical results from sampling in the Broad River at SW-BRAB-2,
downgradient of the main dam of the Active Ash Basin, indicate constituent
concentrations less than applicable 2B criteria, with the exception of hardness.
Several constituent concentrations at SW-BRAB-2 were notably greater than
those detected in background samples.
Analytical results from sampling in the Broad River at SW-BRAB-3,
downgradient of the main dam of the Active Ash Basin, indicate constituent
concentrations less than applicable 2B criteria, with the exception of hardness.
Several constituent concentrations, including boron, at SW-BRAB-3 were greater
than those detected in background samples and similar to concentrations
detected at SW-BRAB-2.
Elevated constituent concentrations, including hardness, at SW-BRAB-2 and SW-
BRAB-3, are likely due to influence from NPDES Outfall 002 discharge rather
than representation from groundwater discharge.
Effluent from NPDES Outfall 002 is comprised primarily of decanted water from
the Active Ash Basin. Discharge Monitoring Reports for Outfall 002 indicate

flow rates of several million gallons per day (Appendix F). Hardness
concentrations measured from water within the Active Ash Basin during AOW
monitoring in April and October 2016 indicate hardness concentrations ranging
from 106 to 127 mg/L (Appendix G). Comparatively, at non -engineered
discharge location S-6/Outfall 106 (which may indicate groundwater conditions
and is adjacent to Outfall 002), hardness concentrations measured during the
April and October 2016 AOW monitoring event (163 and 162 mg/L, respectively)
were similar to Outfall 002, yet flow was estimated to be substantially less at
approximately 22,000 to 54,000 gallons per day. This indicates constituent
loading is also substantially less from non -engineered discharge location S-
6/Outfall 106 and that constituents detected downstream at surface water
sampling location SW-BRAB-2 and SW-BRAB-3 are likely attributable to Outfall
002.
Additionally, as measured during the April and October 2016 AOW monitoring
event, flow at S-6/Outfall 106 was similar to estimated flow rates at non -
engineered discharge location S-3/Outfall 103 (7,000 and 42,000 gallons per day,
respectively, Appendix G) while hardness concentrations detected at S-3/Outfall
103 were nearly three times greater (330 and 338 mg/L, respectively) than at S-
6/Outfall 106. However, hardness concentrations detected in the surface water
sample SW-BRU14-1 located downgradient of S-3/Outfall 103 were notably less
than the 2B and within the range of background concentrations in the Broad
River, indicating constituent loading at the rate of groundwater discharge
upgradient of Outfall 002 does not have a notable effect on surface water quality
in the Broad River.
Detected hardness concentrations at SW-BRAB-3, located farther downstream of
Outfall 002 surface water sample location SW-BRAB-2, are less than
concentrations detected at SW-BRAB-2, illustrating that further mixing with river
water downstream of Outfall 002 reduces constituent concentrations. This
indicates that planned downgradient in -stream monitoring associated with the
draft NPDES permit is sufficient to determine impact on surface water character
downstream of the CAMA ash management areas. This also suggests that
potential loading from groundwater further downstream of Outfall 002 is not
notably altering constituent concentrations in the Broad River.
Prior CAMA sampling locations SW-10A/B/C are located approximately 2,500
feet further downstream from SW-BRAB-3. Detected constituent concentrations
at SW-10A/B/C are less than those detected at SW-BRAB-3 and are less than

applicable 2B criteria. Although samples from SW-10A/B/C were not analyzed
for hardness, historical results from SW-10A/B/C indicate dilution of constituents
downstream of SW-BRAB-2 and SW-BRAB-3 and Outfall 002.
4.2.5 Western Dammed Area of Active Ash Basin
Surface water samples collected downgradient of the western dammed area of
the Active Ash Basin include three locations from within Suck Creek as shown
on Figure 2, 3, and 8. Figure 8 presents the western dammed area of the Active
Ash Basin area of interest and includes the portion of Suck Creek as it passes the
western dam of the Active Ash Basin and southern portions of the Ash Storage
Areas.
Analytical results from sampling in Suck Creek at SW-SC-4, SW-SC-5, and SW-
SC-6, downgradient of the western dammed area of the Active Ash Basin,
indicate constituent concentrations less than applicable 2B criteria. Constituent
concentrations at these three locations were similar to those detected in
background sample SW-2. These results are also consistent with historical
sample results collected from SW-03, located between SW-SC-5 and SW-SC-6,
which were less than applicable 2B criteria.
4.2.6 Southwestern Area of Active Ash Basin
Surface water samples collected downgradient of the southwestern area of the
Active Ash Basin included three locations within Suck Creek and are shown on
Figure 2, 3, and 9. Figure 9 presents the southwestern area of the Active Ash
Basin area of interest and includes the southern portion of the Active Ash Basin,
the background sampling location within Suck Creek (SW-2), and an unnamed
tributary to Suck Creek that emerges south of the Active Ash Basin.
Analytical results from sampling in Suck Creek at SW-SC-1, SW-SC-2, and SW-
SC-3, downgradient of the southwestern area of the Active Ash Basin, indicate
constituent concentrations less than applicable 2B criteria. Constituent
concentrations at these three locations were similar to those detected in
background sample SW-2.

5.0 CONCLUSIONS AND RECOMMENDATIONS
The following conclusions have been developed from the information presented in this
report:
47 Analytical results obtained from surface water samples collected during low
flow conditions indicate that groundwater discharge from the ash basins and
ash storage areas is not resulting in exceedances of standards for surface water
contained in 15A NCAC 2B .0200.
'67 Surface water sample results are consistent with and support previous water
quality data collected for the NPDES permit, CAMA CSA, and groundwater -
to -surface water interaction modeling to demonstrate compliance with 15A
NCAC 02L .0106(1)(6).
0 The exceedance of the water quality standard for hardness measured at SW-
BRAB-2 and SW-BRAB-3 appears to be related to permitted NPDES Outfall 002
rather than groundwater discharges. The seeps in the area are also covered in
the draft permit to demonstrate future compliance with 2B criteria in surface
water.
Based on the findings and conclusions of the surface water monitoring conducted, the
following recommendations are offered:
47 Continue to evaluate MNA as a viable corrective action alternative for
management of coal combustion residuals -affected groundwater at the site.
47 Implement the surface and waste water monitoring programs outlined in the
draft NPDES permit to demonstrate compliance with 2B criteria in the
receiving systems.

Notes:
Spec Cond - Specific Conductance NTU - Nephelometric turbidity unit umhos/cm - Micro mhos per centimeter
S.U. - Standard Unit Deg C - Degrees Celsius DIS - Dissolved
< - concentration not detected at or above the adjusted reporting limit.
B - Target analyte detected in method blank at or above the reporting limit. Target analyte concentration in sample is less
than 1OX the concentration in the method blank. Analyte concentration in sample could be due to blank contamination.
D3 - Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
D6 - The relative percent difference (RPD) between the sample and sample duplicate exceeded laboratory control limits.
No rain was recorded within the on -site rain gage at least 5 days prior to the sampling event (Table 2)
mg/L - Milligrams per liter ORP - Oxidation -Reduction Potential mg - N/L - Milligrams nitrogen per liter
DO - Dissolved oxygen Eh - Redox Potential Temp - Temperature
j - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
J = Laboratory estimated concentration.
J+ = Estimated concentration, biased high.
J- = Estimated concentration, biased low.
M1 - Matrix spike recovery was high: the associated Laboratory Control Spike (LCS) was acceptable.
Prepared by: BER Checked by: MfMS
NA - Not analyzed ug/L - Micrograms per liter NM - Not measun
my - Millivolts TOT- Total
N2 - The lab does not hold accreditation for this parameter.
P4 - Sample field preservation does not meet EPA or method recommendations
U = Results not detected at concentrations which equal the laboratory's metho,
S - Associated calibration check did not meet specified criteria.

Acute and Chronic Mean Concentrations for comparison to 2B standards utilized method detection limits as analyzed values when selected constituent was not detected greater than the detection limit
Acute and Chronic Mean Concentrations for comparison to 2B standards utilized analyzed values when selected constituent was detected greater than the detection limit and less than the reporting limit
The chronic standard for dissolved silver is not hardness dependent and is therefore listed in Table 4.
NM - Not measured
NA - Not analyzed
NE - Not established
j - Estimated concentration greater than the adjusted method detection limit and less than the adjusted reporting limit.
