Technical Memorandum
Date: Friday, May 26, 2017
Project: Marshall Steam Station Ash Basin System
To: Tyler Hardin
From: Chad Hearn
Subject: Additional Background Monitoring Well Determinations — Revision 1
The purpose of this revised technical memorandum (TM) is to address the North Carolina Department of
Environmental Quality's (NCDEQ's) requirement identified below. In addition, this revised TM includes the
justification for additional monitoring wells that should be considered as background wells for the Marshall
Steam Station (MSS) ash basin system as originally presented in the TM dated December 13, 2016.
Following submittal of the TM dated December 13, 2016, Duke Energy submitted the Statistical Methods
for Developing Reference Background Concentrations for Groundwater and Soil at Coal Ash Facilities
(Background Methodology) to DEQ on January 20, 2017. NCDEQ subsequently requested additional
information regarding the Background Methodology via a letter dated April 28, 2017. As part of the April
28, 2017 letter, NCDEQ requested the following information:
• Provide up-to-date digital spreadsheets of raw background groundwater data for each facility
by May 26, 2017, and include, within the raw background data spreadsheet as "strike-
throughs", the individual monitoring data results that Duke Energy believes should be omitted
from the background dataset due to (a) high pH, (b) high turbidity, (c) auto -correlation, (d)
outlier designation, (e) non -detect values that are above 2L/IMAC, or (f) other reasons.
The up-to-date raw background groundwater data for background determinations at MSS are provided in
Table 2 of this revised TM. Note the remainder of the requirements in the April 28, 2017 NCDEQ letter
are addressed in a revision to the Background Methodology under separate cover.
The potential additional background monitoring wells at MSS include GWA-4S/D, GWA-5S/D, GWA-6S/D,
GWA-8S/D, GWA-12S/D/BR, BG-1 BR, and BG-3BR. These potential background wells are being
proposed based on evaluation of the following criteria: groundwater flow direction, groundwater elevation
as compared to the nearest ash basin surface water or porewater elevation, historical analytical results,
and horizontal distance to the ash basin system. Distances and elevations pertinent to the evaluation are
provided in Table 1. Locations for each monitoring well discussed below are shown on Figure 1.
Additional details are provided for each monitoring well cluster on the following pages of this
memorandum.
Historical analytical data for previously evaluated background wells (CAP Part 1) and the potential
background wells listed above are provided in Table 2. The background wells and analytical data are
separated by groundwater flow layer (shallow, deep and bedrock) and a valid sample count is provided
for each constituent. Sample data associated with turbidity reported to be greater than 10 nephelometric
turbidity units (NTU), samples without a recorded turbidity, samples with a pH greater than 8.5, non -detect

FEZ
samples with a method detection limit greater than the respective 2L Standard or IMAC, or samples with
less than a 60 day interval between sample events are denoted with "strike-throughs" and were not
included in the valid sample counts as requested by NCDEQ.
GWA-4S and GWA-4D
Monitoring wells GWA-4S and GWA-41D were installed as part of the Comprehensive Site Assessment
(CSA) activities in May and June 2015 to evaluate groundwater quality and flow direction northwest of the
MSS ash basin. Water level measurements and calculated groundwater elevations from March, June,
and September 2016 have been considered to confirm groundwater elevations compared to the ash
basin and for determining groundwater flow direction in this area of the site.
• Monitoring wells GWA-4S/D are located approximately 550 feet west-northwest of the ash basin
waste boundary. The ground surface elevation at the monitoring well cluster is approximately 899
feet.
• The closest ash basin surface water elevation was measured to be 817.46 feet in June 2016, in
the northwest portion of the ash basin.
• GWA-4S is screened from approximately 49 to 64 feet below ground surface (ft bgs) in the
shallow flow layer (approximately 850 to 835 feet elevation). The average groundwater elevation
calculated from the March, June and September 2016 gauging events was 843.95 feet
(approximately 27 feet higher than the nearest ash basin surface water elevation measured in
June 2016). The lowest groundwater elevation calculated for these sampling events was 843.42
feet (March 2016).
• GWA-41D is screened from approximately 81 to 86 ft bgs in the deep flow layer (approximately
818 to 813 feet elevation). The average groundwater elevation calculated from the March, June
and September 2016 gauging events was 844.54 feet (approximately 27 feet higher than the
nearest ash basin surface water elevation measured in June 2016). The lowest groundwater
elevation calculated for these sampling events was 844.22 feet (March 2016).
• Analytical data included in Table 2 indicate that boron was not reported in GWA-4S and GWA-41D
at concentrations that equal or exceed the laboratory method reporting limit. Chloride was
reported at concentrations approximately one to two orders of magnitude less than the 2L
Standard in GWA-4S and GWA-41D samples. Sulfate was either not detected or reported at
concentrations more than two orders of magnitude less than the 2L Standard in GWA-4S
samples, and at approximately one order of magnitude less than the 2L Standard in GWA-41D.
Based on the justification provided above, groundwater passing through monitoring wells GWA-4S/D
originates upgradient and northwest of the ash basin and is not impacted by the ash basin system.
Therefore, groundwater samples collected from GWA-4S/D represent background water quality relative to
the MSS ash basin system and have been included in the valid background sample counts.
GWA-5S and GWA-5D
Monitoring wells GWA-5S and GWA-51D were installed as part of the CSA activities in July 2015 to
evaluate groundwater quality and flow direction north of the MSS ash basin. Water level measurements
and calculated groundwater elevations from March, June, and September 2016 have been considered for
determining groundwater flow direction in this area of the site. Note that GWA-5S was dry in September
2016.

FEZ
• Monitoring wells GWA-5S/D are located approximately 500 feet north of the ash basin waste
boundary. The ground surface elevation at the monitoring well cluster is approximately 844 feet.
• The closest ash basin surface water elevation was measured to be 803.8 feet in June 2016, in
the northeast portion of the ash basin.
• GWA-5S is screened from approximately 24.5 to 34.5 ft bgs in the shallow flow layer
(approximately 820 to 810 feet elevation). The average groundwater elevation calculated from the
March, June, and September 2016 gauging events was 813.21 feet (approximately 9.5 feet
higher than the nearest ash basin surface water elevation measured in June 2016). The lowest
groundwater elevation calculated for these sampling events was 813.19 feet (March 2016). Note
that GWA-5S was dry during the September 2016 gauging event.
• GWA-51D is screened from approximately 43.5 to 48.5 ft bgs in the deep flow layer (approximately
801 to 796 feet elevation). The average groundwater elevation calculated from the March, June,
and September 2016 gauging events was 813.08 feet (approximately 9 feet higher than the
nearest ash basin surface water elevation measured in June 2016). The lowest groundwater
elevation calculated for these sampling events was 812.69 feet (September 2016).
• Analytical data included in Table 2 indicate that boron was not reported in GWA-5S and GWA-51D
at concentrations that equal or exceed the laboratory method reporting limit. Chloride and sulfate
were reported at concentrations approximately two orders of magnitude less than the 2L
Standard.
Based on the justification provided above, groundwater passing through monitoring wells GWA-5S/D
originates upgradient and north of the ash basin and is not impacted by the ash basin system.
Therefore, groundwater samples collected from GWA-5S/D represent background water quality relative to
the MSS ash basin system and have been included in the valid background sample counts.
GWA-6S and GWA-6D
Monitoring wells GWA-6S and GWA-61D were installed as part of the CSA activities in June and July 2015
to evaluate groundwater quality and flow direction northeast of the MSS ash basin. Water level
measurements and calculated groundwater elevations from March, June, and September 2016 have
been considered for determining groundwater flow direction in this area of the site.
• Monitoring wells GWA-6S/D are located approximately 480 feet northeast of the ash basin waste
boundary. The ground surface elevation at the monitoring well cluster is approximately 843 feet.
• The ground surface elevation at the closest portion of the ash basin waste boundary is
approximately 800 feet. Standing water has been observed in this "finger" of the ash basin, but a
surface water elevation has not been measured. The closest portion of the ash basin waste
boundary is at the upgradient end of this "finger" of the ash basin. Therefore, the surface water
elevation in this finger of the ash basin should be considered less than or equal to 800 feet (or a
maximum of 800 feet).
• GWA-6S is screened from approximately 38 to 48 ft bgs in the shallow flow layer (approximately
805 to 795 feet elevation). The average groundwater elevation calculated from March, June, and
September 2016 gauging events was 804.34 feet (approximately 4 feet higher than the nearest
maximum ash basin surface water elevation). The lowest groundwater elevation calculated for
these sampling events was 803.74 feet (September 2016).
• GWA-61D is screened from approximately 102 to 107ft bgs in the deep flow layer (approximately
741 to 736 feet elevation). The average groundwater elevation calculated from the March, June,
and September 2016 gauging events was 804.14 feet (approximately 4 feet higher than the

FEZ
nearest maximum ash basin surface water elevation). The lowest groundwater elevation
calculated for these sampling events was 803.49 feet (September 2016).
• Groundwater flow direction in the vicinity of GWA-6S/D is from the northeast and flows southwest
toward the ash basin.
• Analytical data included in Table 2 indicate that boron was not reported in any of the GWA-6
wells at concentrations which equal or exceed the laboratory method reporting limit. Chloride and
sulfate were reported at concentrations approximately one to two orders of magnitude less than
the 2L Standard.
Based on the justification provided above, groundwater passing through monitoring wells GWA-6S/D
originates upgradient and northeast of the ash basin and is not impacted by the ash basin system.
Therefore, groundwater samples collected from GWA-6S/D represent background water quality relative to
the MSS ash basin system and have been included in the valid background sample counts.
GWA-8S and GWA-8D
Monitoring wells GWA-8S and GWA-81D were installed as part of the CSA activities in July 2015 to
evaluate groundwater quality and flow direction north of the MSS ash basin. Water level measurements
and calculated groundwater elevations from March, June, and September 2016 have been considered for
determining groundwater flow direction in this area of the site.
• Monitoring wells GWA-8S/D are located approximately 1,075 feet north of the ash basin waste
boundary. The ground surface elevation at the monitoring well cluster is approximately 850 feet.
• The closest ash basin surface water elevation was measured to be approximately 803.95 feet in
June 2016, in the northeast portion of the ash basin.
• GWA-8S is screened from approximately 23 to 38 ft bgs in the shallow flow layer (approximately
827 to 812 feet elevation). The average groundwater elevation calculated from the March, June,
and September 2016 gauging events was 819.37 feet (approximately 15.5 feet higher than the
nearest ash basin surface water elevation measured in June 2016). The lowest groundwater
elevation calculated for these sampling events was 818.97 feet (March 2016).
• GWA-81D is screened from approximately 56 to 61ft bgs in the deep flow layer (approximately
794.5 to 789.5 feet elevation). The average groundwater elevation calculated from the March,
June, and September 2016 gauging events was 818.37 feet (approximately 14.5 feet higher than
the nearest ash basin surface water elevation measured in June 2016). The lowest groundwater
elevation calculated for these sampling events was 818.09 feet (September 2016).
• Analytical data included in Table 2 indicate that boron was not reported in any of the GWA-8
wells at concentrations which equal or exceed the laboratory method reporting limit. Chloride and
sulfate were reported at concentrations approximately two orders of magnitude less than the 2L
Standard.
Based on the justification provided above, groundwater passing through monitoring wells GWA-8S/D
originates upgradient and north of the ash basin and is not impacted by the ash basin system.
Therefore, groundwater samples collected from GWA-8S/D represent background water quality relative to
the MSS ash basin system and have been included in the valid background sample counts.
GWA-12S, GWA-12D, and GWA-12BR
Monitoring wells GWA-12S, GWA-12D, and GWA-12BR were installed offsite in May 2016 to evaluate
groundwater quality and flow direction west of the MSS ash basin. These wells were first sampled in June
4

FEZ
2016. Water level measurements and calculated groundwater elevations from June and September 2016
have been considered for determining groundwater flow direction in this area.
• Monitoring wells GWA-12S/D/BR are located approximately 950 feet west of the ash basin waste
boundary. The ground surface elevation at the monitoring well cluster is approximately 876 feet.
• The closest ash basin surface water elevation was measured to be approximately 800.17 feet in
June 2016, in the southwest portion of the ash basin.
• GWA-12S is screened from approximately 10 to 25 ft bgs in the shallow flow layer (approximately
866 to 851 feet elevation). The average groundwater elevation calculated from the June and
September 2016 gauging events was 860.73 feet (approximately 60 feet higher than the nearest
ash basin surface water elevation measured in June 2016). The lowest groundwater elevation
calculated for these sampling events was 859.92 feet (September 2016).
• GWA-12D is screened from approximately 88 to 93 ft bgs in the deep flow layer (approximately
788 to 783 feet elevation). The groundwater elevation calculated from the September 2016
gauging event was 860.41 feet (approximately 60 feet higher than the nearest ash basin surface
water elevation measured in June 2016). Note that a water level measurement was not provided
for June 2016.
• GWA-12BR is screened from approximately 113 to 118 ft bgs in the bedrock flow layer
(approximately 763 to 758 feet elevation). The average groundwater elevation calculated from the
June and September 2016 gauging events was 858.97 feet (approximately 59 feet higher than
the nearest ash basin surface water elevation measured in June 2016). The lowest groundwater
elevation calculated for these sampling events was 858.51 feet (June 2016).
• Analytical data included in Table 2 indicate that boron was not reported in any of the GWA-12
wells at concentrations which equal or exceed the laboratory method reporting limit. Chloride was
reported at concentrations approximately two orders of magnitude less than the 2L Standard.
Sulfate was reported at approximately one to two orders of magnitude less than the 2L Standard.
Based on the justification provided above, groundwater passing through monitoring wells GWA-12S/D/BR
originates upgradient and west of the ash basin and is not impacted by the ash basin system. Therefore,
groundwater samples collected from GWA-12S/D/BR represent background water quality relative to the
MSS ash basin system and have been included in the valid background sample counts.
BG-1 BR
Monitoring well BG-1 BR was installed adjacent to existing background wells BG-1 S/D in April 2016 to
further evaluate groundwater quality and flow characteristics in the bedrock flow layer to the northeast of
the ash basin. As documented in Appendix B of the MSS CAP Part 1, BG-1 S/D were evaluated and
confirmed to be background wells. BG-1 BR was first sampled in April 2016. Water level measurements
and calculated groundwater elevations from June and September 2016 have been considered for
determining groundwater flow direction in this area.
• Monitoring well BG-1 BR is located approximately 5,700 feet northeast of the ash basin waste
boundary. The ground surface elevation at the monitoring well cluster is approximately 815 feet.
• The closest ash basin surface water elevation was measured to be approximately 786.81 feet in
June 2016, in the southeast portion of the ash basin.
• BG-1 BR is screened from approximately 84 to 89 ft bgs in the bedrock flow layer (approximately
731 to 726 feet). The average groundwater elevation calculated from the June and September
2016 gauging events was 800.79 feet (approximately 14 feet higher than the nearest ash basin

FEZ
surface water elevation measured in June 2016). The lowest groundwater elevation calculated for
these sampling events was 799.68 feet (June 2016).
Analytical data included in Table 2 indicate that boron was not reported in monitoring well BG-
1 BR at concentrations which equal or exceed the laboratory method reporting limit. Chloride and
sulfate were reported at concentrations approximately two orders of magnitude less than the 2L
Standard.
Based on the justification provided above, groundwater passing through monitoring well BG-1 BR
originates side -gradient and northeast of the ash basin and is not impacted by the ash basin system.
Therefore, groundwater samples collected from BG-1 BR represent background water quality relative to
the MSS ash basin system and have been included in the valid background sample counts.
BG-3BR
Monitoring well BG-3BR was installed adjacent to existing background wells BG-3S/D in April 2016 to
further evaluate groundwater quality and flow characteristics in the bedrock flow layer to the northeast of
the ash basin. As documented in Appendix B of the MSS CAP Part 1, BG-3S/D were evaluated and
confirmed to be background wells. BG-3BR was first sampled in April 2016. Water level measurements
and calculated groundwater elevations from June and September 2016 have been considered for
determining groundwater flow direction in this area.
• Monitoring well BG-3BR is located approximately 4,100 feet northeast of the ash basin waste
boundary. The ground surface elevation at the monitoring well cluster is approximately 865 feet.
• The closest ash basin surface water elevation was measured to be approximately 786.81 feet in
June 2016, in the southeast portion of the ash basin.
• BG-3BR is screened from approximately 105 to 110 ft bgs in the bedrock flow layer
(approximately 760 to 755 feet). The average groundwater elevation calculated from the June
and September 2016 gauging events was 832.18 feet (approximately 45 feet higher than the
nearest ash basin surface water elevation measured in June 2016). The lowest groundwater
elevation calculated for these sampling events was 831.29 feet (June 2016).
• Analytical data included in Table 2 indicate that boron was not reported in monitoring well BG-
3BR at concentrations which equal or exceed the laboratory method reporting limit. Chloride and
sulfate were reported at concentrations approximately one to two orders of magnitude less than
the 2L Standard.
Based on the justification provided above, groundwater passing through monitoring well BG-3BR
originates side -gradient and northeast of the ash basin and is not impacted by the ash basin system.
Therefore, groundwater samples collected from BG-3BR represent background water quality relative to
the MSS ash basin system and have been included in the valid background sample counts.

Notes:
1. Elevations presented in North American Vertical Datum (NAVD) 88.
2. The groundwater elevations presented are the averaged based on available groundwater elevation measurements from sampling/gauging events at the site.
3. Ash basin surface water elevations closest to monitoring wells were measured during the June 2016 gauging event, except for GWA-6S/D (see note below).
4. The closest ash basin surface water elevation to GWA-6S/D should be considered less than or equal to 800 feet due to topography and the lateral extent of
the ash basin waste boundary.
* = Groundwater flow direction estimated based on topography and slope -aquifer system.

Notes
"Strike-throughs" indicates samples that will not be used in the initial background dataset for determining proposed provisional background threshold values (PPBTVs).
The criteria for "strike-throughs" (as stipulated by NCDEQ) requires Duke Energy to omit samples due to pH > 8.5, turbidity >10 NTU, non -detect samples with a
method detection limit (MDL) > 2L Standard or IMAC, or less than a 60 day interval between sample events.
Q - Bold highlighted concentration indicates exceedance of the 15A NCAC 02L Standard or IMAC, Appendix 2, April 1, 2013.
pm = micron
pg/L = micrograms per liter
pS/an = microsiemens per centimeter
ft = feet
mg/L = milligrams per liter
Eh values were calculated by adding 200 mV to the field -measured ORP value. Depending on the field meter used, Eh values calculated using this formula can vary by +/- 5 mV.
mV = millivolts
NTU - nephelometric turbidity units
DHHS = North Carolina Department of Health and Human Services
pCi/L = picocuries per liter
DO = dissolved oxygen
SU = standard unit
GW = groundwater
J = laboratory estimated concentration
GWQS = groundwater quality standard
J- = estimated concentration, biased low
IMAC = Interim Maximum Allow Concentration
J+ = estimated concentration, biased high
N = normal
U = results not detected at concentrations which equal the laboratory's method reporting limil
NS = no standard
02L = North Carolina groundwater standards as specified in T15A NCAC 02L
T = total
D = dissolved
TDS = total dissolved solids
Deg C = degree Celsius
TOC = total organic carbon
