1. INTRODUCTION
1.1 Overview
Geosyntec Consultants of North Carolina, PC (Geosyntec) conducted a subsurface investigation
within the Lay of Land Area (LOLA) at the L.V. Sutton Energy Complex (Sutton) located near
Wilmington, New Hanover County, North Carolina (NC). The purpose of the subsurface
investigation was to establish target base of excavation grades in LOLA, where coal combustion
residuals (CCR) to be excavated are present underwater. This report was prepared to document
the findings from the subsurface investigation, referred to as Closure Investigation hereafter, and
present established target base of excavation grades.
1.2 Background and Purpose
The NC General Assembly passed Senate Bill 729 in August 2014, known as the Coal Ash
Management Act (CAMA). CAMA requires the CCR basins at Sutton to be closed by August
2019. While CAMA does not require excavation of CCR in LOLA, Duke Energy Progress, LLC
(Duke Energy) voluntarily plans to excavate CCR within LOLA for closure, and place the
excavated CCR in the onsite CCR landfill. Figure 1 presents the locations of LOLA and the onsite
CCR landfill along with other significant site features.
On 13 June 2017 Duke Energy proposed a “pre-excavation” approach for confirmatory testing
upon completion of CCR excavation for verification purposes. This approach was approved via
email by Mr. Steven M. Lanter of NCDEQ on 14 June 2017 (Appendix A). The proposed approach
consisted of the following five steps:
i. Advance borings on a 100-ft by 100-ft grid within LOLA prior to completion of CCR
excavation;
ii. Identify the CCR/soil interface by visual classification of samples collected during the
borings per ASTM D 2488 [ASTM, 2017];
iii. Collect samples below the CCR/soil interface identified in the previous step and conduct
polarized light microscopy (PLM) examination on the collected sample;
a. Samples with less than 50 percent CCR are considered passing the criteria for closure
by excavation;
b. If a sample has greater than 50 percent CCR, an additional sample will be collected at
approximately 1-ft increment below the initial sample and submitted for PLM
examination;

iv. Develop target base of excavation grades based on the top elevation of the PLM sampling
interval, where the sample contains less than 50 percent CCR, at each of the boring
locations; and
v. Excavate/dredge, at a minimum, to the target base of excavation grades.
A third-party consultant performed an additional investigation to evaluate groundwater quality and
potential impacts on native soils in LOLA, in accordance with the technical direction from
NCDEQ presented in Appendix A. The additional investigation is beyond the scope of this report
and not presented herein.

2. CLOSURE INVESTIGATION
2.1 Overview
The Closure Investigation consisted of: (i) Geoprobe® borings within LOLA to identify the
CCR/soil interface by visual classification (ASTM D 2488) and collect PLM samples below the
CCR/soil interface; and (ii) laboratory examination via PLM to verify findings from the Geoprobe®
borings. Underground utility surveying was not performed prior to the Geoprobe® borings since
an active gas line has been identified recently and no additional active utility lines were identified
during previous subsurface investigations. The field and laboratory components of the Closure
Investigation are described in Sections 2.2 and 2.3, respectively.
2.2 Geoprobe® Borings
The Geoprobe® borings were performed by Cascade Drilling of Tampa, Florida under the
supervision of Geosyntec engineers from 27 July through 4 August 2017. A total of 177 borings
(LGB-1 through LGB-177) were advanced on an approximately 100-ft by 100-ft grid within
LOLA. Some boring locations were adjusted from the grid based on field conditions (e.g., safety
and accessibility). The boring locations were surveyed and staked out by Cape Fear Engineering
of Belville, NC.
The Geoprobe® borings were terminated within soil approximately 5- to 10-ft below the CCR/soil
interface, 5-ft to 25-ft below ground surface (bgs). Samples were collected using either 1.25-inch
(in) diameter Dual-Tube or 1.5-in diameter Macro-Core® (MC5) samplers. The MC5 sampler was
typically used in challenging subsurface conditions (e.g., heave or “cave-in” within boreholes) or
when greater sample recovery was required to collect samples for PLM examination. The CCR
and/or soil recovered in the Geoprobe® samplers were visually classified and logged by Geosyntec
engineers. Once the CCR/soil interface was identified, a sample was collected for PLM
examination approximately 2-ft below the CCR/soil interface, as directed by Duke Energy, and
placed into glass jars provided by Duke Energy’s Metallurgy Laboratory. Up to two additional
samples were collected at approximately 1-ft intervals below the initial sample interval. These
samples were placed in Ziploc® bags and stored in the Duke Energy field office in case additional
laboratory testing was required. Subsequently, sample jars were placed in bubble-wrap bags and
shipped to Duke Energy’s Metallurgy Laboratory with completed chain-of-custody forms.
2.3 Polarized Light Microscopy Examination
A total of 181 samples collected from the Geoprobe® borings (includes four additional samples to
minimize iterations and act as secondary samples) were shipped to Duke Energy’s Metallurgy
Laboratory. Subsequently, the samples were shipped to RJ Lee Group, Inc. (RJLG) of
Monroeville, Pennsylvania for PLM examination, directly contracted to Duke Energy, to verify
findings from the Geoprobe® borings. RJLG has ISO/IEC 17025:2005 accreditation for materials

testing using PLM (https://www.iso.org/standard/39883.html and http://www.rjlg.com/about-
us/accreditations/). RJLG used PLM to quantify the amount of CCR in the samples examined,
adopting a test method presented in EPA/600/R-93/116 [USEPA, 1993].

3. CLOSURE INVESTIGATION RESULTS
3.1 Findings
The “as-built” Geoprobe® boring locations are shown on Figure 2. Boring logs are provided in
Appendix B. The PLM results are summarized in Table 1 and the reports prepared by RJLG are
presented in Appendix C. The amount of CCR reported from the PLM examinations ranged from
0 (not detected) to 40 percent and no PLM results indicated exceedance of 50 percent CCR in the
samples.
3.2 Target Base of Excavation Grades
Historical investigations indicate the presence of CCR beneath a portion of the LOLA North Dike,
which will be excavated as part of the LOLA closure activities. The target base of excavation
grades were established by interpolating the information (i.e., the top elevation of the PLM
sampling interval where the sample contains less than 50 percent CCR) at each of the Geoprobe®
borings and incorporating the historical investigation results within the LOLA North Dike. The
target excavation grades were developed using Autodesk® AutoCAD® Civil 3D® and are presented
on Figure 3. The target base of excavation grades represent minimum excavation elevations in
LOLA. The elevation of target base of excavation at each of the boring locations is also
summarized in Table 2.

Subject:RE: Sutton 1971 Ash Basin - Bottom of Ash Determination - June 2017
John, 

Thanks for the summary of our discussions related to development of a strategy to address soil closure guidelines for coal 
ash basins with ash below the water table.  Analyzing solid phase samples in this site conditions scenario is problematic 
concerning obtaining representative sample results for evaluation of protection of groundwater criteria.  The Division 
grants approval for an alternate approach to sampling ash, soil, and groundwater beneath the water table to evaluate 
groundwater quality and potential impacts from soil beneath ash basins following technical direction provided below for 
the four proposed locations: 

 Collect soil samples from the interval 0 to 5‐feet below the base of the ash/ soil interface along established 
flowpath transects.  
o Analyze soil samples obtained below the water table for hydrous ferric hydroxide and hydrous aluminum 
oxide. 
o Soil samples for laboratory analysis must be collected in a manner  that  will  ensure  a  relatively  uniform
distribution of particles throughout the 6‐inch sample.
o Record physical parameters of the soil samples obtained.

 Collect groundwater samples from the interval 0 to 5‐feet below the base of the ash/ soil interface along 
established flowpath transects  
o Non‐filtered (total) groundwater samples will be analyzed for constituents in the CAMA groundwater analyte 
list. 
o At one split sample will be collected and analyzed for quality assurance/quality control. 
o Since turbidity can be an issue with respect to collection of representative groundwater samples, the Division 
encourages Duke Energy to make an effort to develop wells to reduce potential for samples that may not 
meet established CAMA criteria. Filtration of samples in the laboratory may be considered. 

Soil and groundwater analytical results will be used to calibrate fate/transport and geochemical models to evaluate 
potential impacts along the soil to groundwater pathway. Soil closure guidelines will be revised accordingly in the near 
future.  Please contact me if you have additional questions or comments. 

Best regards, 
Steve

Subject: Sutton 1971 Ash Basin ‐ Bottom of Ash Determination ‐ June 2017 

Steve – per our prior discussions on determination for full excavation of ash basins when ash is underwater, we have 
primarily discussed the 1971 ash basin at Sutton but the discussion will have impacts to other Duke Energy sites.  Again, I 
believe Duke Energy and DEQ are in agreement to complete borings on 100 foot grid to visually determine bottom of 
ash.  Just below that visual interface, soil samples will be collected (~1 foot increments) and submitted for PLM 
analysis.  Where PLM is determined to be less than 50%, the bottom of the basin will be determined at that location and 
a new bottom of ash basin figure will be re‐calculated.  Duke Energy will then dredge to those elevations and provide 
confirmation to DEQ that the dredge did go to those elevations and therefore all ash has been excavated. 

From the attached figure, Duke Energy will complete about 235 borings within the footprint of the 1971 ash basin.  Our 
most current discussions centered on groundwater/soil sampling from temporary wells.  Duke Energy plans to install a 
total of 4 temporary wells at four separate boring locations.  Two of those temporary wells will be located on a transect 
(transect from current geochemical & groundwater model) within the deep part of the basin and the two remaining 
temporary wells will be located on a transect in the shallower part of the 1971 ash basin.  The top of the temporary well 
screen will be targeted at five below the bottom of the ash/soil interface.  A groundwater sample will be collected and 
analyzed for the CAMA groundwater parameter list.  A soil sample will also be collected at that level of 5 feet below the 
ash/soil interface and analyzed for hydrous ferric oxide (HFO) and gibbsite (HAO).   All borings will be grouted after work 
is complete. 

A contractor will begin mobilization at Sutton this Friday with drilling slated to begin early next week.  Duke Energy 
requests from DEQ confirmation that borings can begin next week while we continue to discuss soil/groundwater 
sampling that is required at the four temporary well locations.  This confirmation is requested from DEQ ASAP. 

Duke Energy plans to move the boring equipment to the LOLA area after work in the 1971 ash basin is completed.  Duke 
Energy plans to complete the PLM work as described above and install two temporary wells in the LOLA area for same 
sampling (groundwater and soil) as that described above for the 1971 ash basin.   

Please let me know of any questions on the above information.  thanks

No responsibility or liability is assumed for the manner in which these results are used or interpreted. * This test report relates to the items tested. * Any reproduction of this document must include the entire document in order for the report to be valid. * This report may not be used to claim product endorsement by NVLAP Lab Code 101208-0 or any agency of the U.S. Government. * Sample(s) for this project were analyzed at our: Monroeville, PA (AIHA # 100364, NVLAP # 101208-0, NY ELAP # 10884) facility. * If RJ Lee Group, Inc. did not collect the samples analyzed, the verifiability of the laboratory’s results is limited to the reported values. * For the purposes of this method, Fly Ash is defined as any particle consistent with Coal Ash. * The method reporting level is 1% and anything <1% is considered a not-detected. Quartz – Angular anisotropic particulate with low relief. Feldspar – Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning. Clay – Sheet silicates with polycrystalline or display non-uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns. Opaques – Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture. Fly Ash – Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles. Organic Particulate – Pollen, plant and insect matter, and carbonaceous matter. Carbonates – High birefringent, can be rhombohedral, with high relief. Diatoms – Silica rich isotropic particles with various morphologies. Mica – Sheet silicate with moderate to high relief and low birefringence, mono-crystalline, and normal extinction. Miscellaneous Silicate – Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify. Amphibole – Elongated anisotropic particulate with moderate to high relief. Coal – Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color. <1% Fly Ash – Fly Ash observed, none counted. ND – No Fly Ash detected. 6 Page 6 of AOH1046326-0 350 Hochberg Road, Monroeville, PA 15146 | Phone: [phone] | Fax: [phone] Disclaimer Notes 8-15-17 Page 18 of 22

Quartz – Angular anisotropic particulate with low relief. Feldspar – Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning. Clay – Sheet silicates with polycrystalline or display non-uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns. Opaques – Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture. Fly Ash – Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles. Organic Particulate – Pollen, plant and insect matter, and carbonaceous matter. Carbonates – High birefringent, can be rhombohedral, with high relief. Diatoms – Silica rich isotropic particles with various morphologies. Mica – Sheet silicate with moderate to high relief and low birefringence, mono-crystalline, and normal extinction. Miscellaneous Silicate – Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify. Amphibole – Elongated anisotropic particulate with moderate to high relief. Coal – Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color. <1% Fly Ash – Fly Ash observed, none counted. ND – No Fly Ash detected. 9 Page 9 of AOH1046328-0 350 Hochberg Road, Monroeville, PA 15146 | Phone: [phone] | Fax: [phone] Disclaimer Notes 8-15-17 Page 22 of 22

Quartz – Angular anisotropic particulate with low relief. Feldspar – Angular to blocky anisotropic particulate, low to moderate relief, biaxial, can have polysynthetic twinning. Clay – Sheet silicates with polycrystalline or display non-uniform extinction with low to moderate relief, and zero to low birefringence. Clay also refers to particles that are less than 2.0 microns. Opaques – Opaque is a generic term for a particle that does not transmit light. Opaque minerals are distinguished from opaque bottom ash based on morphology of fracture. Fly Ash – Isotropic to opaque spheres, agglomeration of spheres, and angular ash particles. Organic Particulate – Pollen, plant and insect matter, and carbonaceous matter. Carbonates – High birefringent, can be rhombohedral, with high relief. Diatoms – Silica rich isotropic particles with various morphologies. Mica – Sheet silicate with moderate to high relief and low birefringence, mono-crystalline, and normal extinction. Miscellaneous Silicate – Isotropic and anisotropic silicates, with low to high relief, identification unsure and beyond the scope of the method to identify. Amphibole – Elongated anisotropic particulate with moderate to high relief. Coal – Irregular to angular particles with moderate opacity, edges and thin particles are reddish brown in color. <1% Fly Ash – Fly Ash observed, none counted. ND – No Fly Ash detected. 6 Page 6 of AOH1046411-0 350 Hochberg Road, Monroeville, PA 15146 | Phone: [phone] | Fax: [phone] Disclaimer Notes 8-18-17 Page 18 of 22
