Subject: Letter Report — Stage I Work
Response to Third Party Recommendations for Ash Pond Dikes (HFLEE 9)
H.F. Lee Station, Goldsboro, NC
Duke Energy Corporation
Dear Mr. Smith:
Duke Energy Corporation (DEC) contracted with Geosyntec Consultants of North Carolina, P.C.
(Geosyntec) to evaluate the recommendations provided by a third party engineering firm for the
ash pond dikes at the H.F. Lee (Lee) station in Goldsboro, North Carolina. Geosyntec has been
working on evaluating conceptual closure options for the ash ponds at Lee since May 2013 as
part of a separate project for DEC. During the conceptual closure options evaluations, Geosyntec
reviewed existing subsurface investigation data and historical dam inspection reports, as well as
conducted a preliminary field geotechnical investigation program. The area referred to in the
comment by the third party engineering firm was not evaluated by Geosyntec as part of the
conceptual closure evaluation work.
Messrs. Kula Kulasingam, Ph.D., P.E., Beau Hodge, P.G. and Lauren Wellborn, P.E. from
Geosyntec conducted a site visit to Lee on 12 June 2014 to inspect the locations that are relevant
to the third party comments assigned by DEC for evaluation by Geosyntec. They were escorted
by Mr. Eugene Smith of DEC to assist in identifying the relevant locations. Subsequently, Ms.
Wellborn visited the site on 15 July 2014 to inspect the dike areas not covered during the 12 June
2014 site visit. Messrs. Chris Keenan, P.E. and Cedric Fairbanks, Ph.D., P.E. of DEC
accompanied her during the dike inspection. This letter report (Report) is prepared based on: (i)
information gathered by Geosyntec during the above mentioned site visits; and (ii) limited field
investigation performed by Geosyntec from 7 July through 9 July 2014. The remainder of this
Report presents the overall project approach and response for comment HFLEE-9.

PROJECT APPROACH
The dikes of the active ash pond at Lee are regulated under the North Carolina Department of
Environment and Natural Resources (NCDENR) Dam Safety regulatory program, while the
inactive pond dikes and the Lay of Land Area (LOLA) addressed in this Report are not. The term
active pond is used herein to be consistent with historical reports for the ponds, even though no
discharges are being routed to the active pond since late 2012. It is our understanding that DEC's
overall project approach consists of the following:
• Evaluate the third party recommendations, perform analyses (if needed), and develop
responses to the recommendations (Stage 1).
• Perform detailed design (if needed), evaluate constructability, and develop permit and
construction documents (Stage I1).
• Perform field implementation and monitoring of construction (if needed) and develop as -
built documentation for regulatory submittal (Stage III).
The previous closure option evaluations identified the preferred closure option to include
removal of ash from the inactive ponds and placement within the footprint of the active pond,
which will then be closed in place with an engineered cover. This option was selected based on
the Kepner-Tregoe (K-T) analysis performed by DEC and Geosyntec's conceptual closure
evaluation work. This option was selected in consideration of the inactive pond dike crests being
below the 100-year flood elevation. While the LOLA was not considered as part of the closure
evaluation previously, it is noted that the LOLA and its dikes are also located below the 100-year
flood elevation. To the extent possible, Geosyntec has considered the effect of the selected
closure option as it relates to the implementation of the third party comments.

COMMENT AND RESPONSE FOR HFLEE - 9
HFLEE-9
"There is potential risk of loss of CCB materials from the Lay -of -Land Storage Area during
heavy rainfall events or flooding from the Neuse River."
Recommended Action: "Investigations should be performed to characterize the extents of ash
materials in the Lay -of -Land Storage Area. In addition, the area should be included in routine
monitoring activities at the site. Monitoring should include observations for erosion and/or
runoff of materials from this area into the surrounding floodplain."
Response:
To characterize the lateral and vertical extents of coal combustion residuals (CCRs) in the
LOLA, Geosyntec reviewed previous efforts conducted by AMEC in May 2013, and conducted a
limited field investigation in July 2014, which employed the use of hand auger and direct push
technology (DPT) soil borings for visual characterization of CCRs.
AMEC completed five hand auger borings (HA-1 through HA-5) in May 2013, to depths ranging
from 2.0 to 9.0 feet (ft) below ground surface (BGS). Based on Geosyntec's conversation with
Mr. Scott Auger (AMEC), we understand that the depth of each boring indicates the base of
CCRs which were visually observed by an AMEC field representative at each location. The
depth from land surface to the top of CCRs was reportedly not recorded by AMEC during this
field investigation. Based on observations from these five borings, AMEC estimated that an area
of approximately 430,967 square feet (sf) (9.9-acres) was impacted with CCRs at the LOLA.
Using an average depth of observed CCRs, AMEC estimated that the CCR impacted volume was
approximately 83,000 cubic yards (cy). The results of AMEC's May 2013 characterization
efforts are provided in Attachment HFLEE-9-A.
In order to further refine and delineate the lateral and vertical extent of CCRs at the LOLA,
Geosyntec conducted a limited field investigation from 7 July through 9 July 2014. This limited
field investigation consisted of the advancement of 18 DPT soil borings (DPT-1 through DPT-3,
DPT-3A, DPT-3B, DPT-3C, DPT-4 through DPT-10, and DPT-24 through DPT-28) and 16 hand
auger borings (11 LOLT HA through 23 LOLT HA, and 29 LOTL HA through 31 LOTL HA).
Generally, DPT collection was utilized to characterize areas where access with a drill rig was
GK5637/GA 140490_Duke_HFLEE_ABSAT Comments (9) Letter Report.doc

feasible. The remaining areas were sampled with hand augers. Borings were typically advanced
to a total depth of at least 1 foot below the observed bottom of CCR impacts. If no CCR impacts
were found, borings were advanced to a total depth of 10 ft BGS (DPT) or 6 ft BGS (hand
auger). The spatial location of each boring was recorded in the field using a hand-held GPS
device. The maximum depth of CCRs identified by Geosyntec was 8 ft BGS (DPT-3A) and the
maximum CCR thickness observed by Geosyntec was 7.25 ft (DPT-9). Boring logs which
present Geosyntec's field observations and lithologic descriptions at each DPT and hand auger
boring location are presented in Attachment HFLEE-9-B. Selected photographs representative
of Site conditions from selected soil borings are presented in Attachment HFLEE-9-C.
Figures depicting Geosyntec's analysis and interpretation of field observations and AMEC-
provided information are presented in Attachment HFLEE-9-D. Herein, Geosyntec presents:
• The location of each of AMEC's May 2013 and Geosyntec's July 2014 soil boring
locations (Figures 1A and 1B).
• Surface topography in the LOLA based on Geosyntec's review of the North Carolina
Department of Transportation (NCDOT) LIDAR topographic map for the area (Figures
1A and l B).
• An estimate of the lateral extent of CCRs in the LOLA based on Geosyntec's field
observations and interpolated using kriging calculations (Figure 2). Geosyntec estimates
this area to be 393,246 sf (9.0-acres). Please note that, in some areas, the extent of ash
was interpreted outside of the area where CCRs were observed.
• An estimated surface contour of the "top of ash" based on Geosyntec's field observations
(Figure 2).
• An estimated surface contour of the "bottom of ash" based on Geosyntec's and AMEC's
field observations (Figure 3). The upper and lower vertical bounds of CCR materials
was estimated based on observations from Geosyntec's DPT and hand auger borings.
The respective elevations noted in the borings were used to generate top and bottom
surfaces encapsulating the CCR materials. The elevations were utilized in ACAD Civil
3D to triangulate and generate a triangulated irregular network (TIN) surface.

• An estimate of ash volume based on the top of ash and bottom of ash surface contours,
and volume isopach contours (Figure 4). Geosyntec estimates that 53,650 cy of ash is
present in the LOLA.
• An estimate of an excavation volume based on the surface topography and bottom of ash
contour, and volume isopach contours (Figure 5). Geosyntec estimates this volume to be
72,151 cy. This estimate has assumed that the soil overburden covering the ash material
is included in the excavation volume. Excavation sidewall sloping has not been
estimated and/or included in this volume estimation.
• Two cross sections depicting the estimated extent of ash in the LOLA (Figure 6).
As noted earlier, the dikes and interior of the LOLA are located below the 100-year flood
elevation. Boring logs indicate that zero to a few feet thick organic soil with leaf litter cover the
CCR materials in the LOLA. The dikes along the Neuse River side are one to three feet higher
than the interior area, while dikes are not visible along the access road around the cooling pond.
The above mentioned dikes are not visible in the NCDOT LIDAR topographic map.
Selected photographs taken during the site visit on 15 July 2014 are provided in Attachment
HFLEE-9-E. Dikes have vegetation growing on them. Dikes appear to be in reasonably good
condition, while there are certain locations with signs of erosion, slumping, and development of
low points.
Attachment HFLEE-9-F summarizes the specific observations and recommendations by the
third party engineering firm, and discusses Geosyntec's observations based on site visits and field
work. Based on the information discussed in Attachment HFLEE-9-F, including the challenges
associated with accessing the area for inspection, monitoring, and maintenance, it is
recommended that DEC considers the preparation of plans for excavation and disposal of the
CCR, either in the active pond (permanently or temporarily, if allowed by NCDENR) or hauling
off -site for disposal in a landfill.
While a permanent solution is being prepared, Geosyntec recommends doing the repairs of the
low spots along the Neuse River as a short term risk mitigation measure against high frequency
storm events. The low spots should be filled in with clayey material to the top of the surrounding
dike. The existing pipe should be decommissioned and animal burrows should be evaluated to
see if they are active; inactive burrows should be filled to prevent preferential flow paths from

forming. An access path should be cleared and maintained to facilitate future inspections of the
area.

Mitigation Options Evaluation

Comment by Third Party Engineering Firm
There is potential risk of movement/washout of
materials from the lay of land disposal area
during heavy rainfall events or flooding from
the Neuse River.
The lay of land disposal area should be
included in routine monitoring activities at the
site. Monitoring should include observations of
erosion and/or runoff of materials from this
area and to surrounding flood
plain. Downstream berm areas should be a
focus of monitoring. This area is heavily
wooded so pathways to perform
inspection/monitoring will need to be cut in
while limiting the disturbance that could allow
material to move out of the lay of land area.
Response and mitigation procedures for this
area should be included in the facility's
emergency response plans.

MITIGATION OPTIONS EVALUATION
Comment by Geosyntec
The LOLA is located below the 100-yr flood plain,
and therefore, wash out potential is present. Low
spots in certain dike locations along the Neuse River
present limited washout potential. Dike was not
observed along the cooling pond. Limited organic
soil and leaf litter provides some cover and erosion
protection.
Agreed. It is relatively easier to monitor the LOLA
boundary along the access road around the cooling
pond. However, monitoring the downstream dike
along the Neuse River poses access and safety
challenges. The soil along the river bank is slippery
and may not be accessible based on river levels. The
LOLA area also has an adjacent area with ponded
water.
Agreed.
Proposed Solution
Repair the low spots on the dikes along the Neuse River
as a short term risk reduction measure against high
frequency storm events..
Consider relocating the ash to the active ash basin or
offsite disposal as a long term risk elimination measure.
Monitoring is recommended as long as the CCR
materials remain in the LOLA. Small walking access
paths (with gravel as needed) are recommended to be
maintained to facilitate access and monitoring.
Inspection and monitoring frequency shall not be less
than the frequency used at present for the inactive ponds
at Lee. Additional monitoring after severe storm events
is recommended.
It is noted the use of heavy riprap amour or buttressing
the dike slopes along the Neuse river will involve
floodway permitting challenging. It is recommended that
all low spots on the dikes be filled in and compacted.
Walking the dikes with a contractor and addressing the
issues is recommended due to the difficulty in conducting
field survey in this heavily wooded and difficult access
area at this time.
It is recommended that material supplies (e.g. sand bags)
and other items required in the emergency action plan for
the site be maintained onsite to address any potential
release of CCR from the LOLA as well.
