Dear Mr. Mussler:
526 South Church Street
Charlotte, NC 28202
In general accordance with the CCR Surface Impoundments Closure Guidelines for Protection of
Groundwater provided by the Division of Water Resources on November 4, 2016, Duke Energy Carolinas,
LLC (DEC) has completed the removal of CCR at Riverbend Steam Station. Duke Energy submitted a letter
to NCDEQ dated March 21, 2019 to provide notification that dewatering and removal of CCR from the
Riverbend Steam Station surface impoundments was completed on March 16, 2019. The letter also stated
that Duke Energy will submit the CCR Visual Removal Verification Report by April 30, 2019. The enclosed
report from Wood Environment & Infrastructure Solutions, Inc. includes documentation of visual
observation of CCR removal and PLM sampling results.
If you have any questions on the enclosed information, please contact me at bristol.grohol@duke-

Wood Project No. 7810-16-0625
Dear Mr. Varner:
Wood Environment and Infrastructure Solutions, Inc. (Wood) is pleased to submit this report documenting
observations of CCR removal by visual methods at Riverbend Steam Station. We conclude that visual CCR
removal verification criteria has been satisfied in general accordance with Section 3.0 of "Excavation Soil
Sampling Plan, Riverbend Steam Station Ash Basin System, Rev. 2, dated December 2018 (Attachment 1),
and in accordance with the soil closure guidelines Duke Energy received from the North Carolina
Department of Environmental Quality (NCDEQ) on November 4, 2016. This report documents the
completion of ash fill removal from the ash basin, cinder pit and ash stack areas. Closure of the primary
ash basin and secondary ash basin by removal is required by the North Carolina Coal Ash Management
Act of 2014. Excavation within the limits of the ash stack and cinder pit is required by a court order.
Background
The ash basin system is located at Duke Energy's Riverbend Steam Station in Mount Holly, North Carolina
as shown in Figure 1. The original ash basin system consisted of a single basin commissioned in 1957 but
was divided into a primary ash basin and a secondary ash basin by constructing an intermediate dam
(GASTO-99) in 1979. The intermediate dam was removed in February 2017 as part of the excavation
project. The estimated surface area of the combined ash basin is approximately 69 acres. The ash stack,
also known as the "dry stack", is an area of ash fill constructed with ash removed from both the primary
and secondary ash basins, which covers approximately 29 acres. The cinder pit is a triangular area of
approximately 13 acres located on the north side of the rail spur (Figure 2) and was used as a storage area
for bottom ash (cinders). A total of 5.35 million tons of material was disposed off -site (including soil
commingled with CCR), slightly over the 4.8 to 5.2 million ton pre -excavation estimates.

Wood Project No. 7810181025
The material was disposed at the following facilities:
• Waste Management R&B Landfill, Homer, GA (15,762 tons)
• Marshall Steam Station, FGD and Industrial Landfills, Catawba Co. NC (88,745 tons)
• Brickhaven Structural Fill, Chatham Co. NC (5,227,258 tons)
• Republic Services Charlotte Motor Speedway Landfill (19,543 tons)
Field Evaluation
Field evaluation consisted of conducting visual observations after removal of CCR and collecting samples
for testing utilizing polarized light microscopy (PLM). Photographic images were taken and samples were
obtained in the vicinity of each grid point marked on Figure 2. After the vertical extension of the primary
dam was removed, a column of eleven points was added to the grid between columns 19 and 20 (and in
one case between 20 and 21) to capture the exposed crest of the lowered primary dam. These points are
identified by the nearest regular grid point ID plus an offset indicator (i.e., O21W50 indicates a point
approximately 50 feet west of grid location 021). Wood's construction quality assurance (CQA) personnel
conducted visual observations and collected samples between February 11, 2017 and March 16, 2019 for
PLM testing and evaluation.
Visual CCR Removal Verification Results
CCR removal was evaluated based on three criteria:
1. comparison of estimated bottom of CCR grades to post-CCR removal grades;
2. visual observation; and
3. PLM evaluation.
Grade Comparison
Due to the limited quality of historical data used for the initial estimate of bottom of CCR grades, grade
comparison is an unreliable method for verifying ash removal. However, the data is presented in Table 1.
Visual Observation
Visual observation of CCR removal was performed on a 100-foot by 100-foot grid as shown in Figure 2.
The photographic log is included in Attachment 2.
PLM Evaluation
Sampling at depths of 0 — 6 inches and 24 — 30 inches and visual soil classifications were conducted on
the 100-foot grid as shown in Figure 2 for PLM evaluation. Hand auger refusal at depths shallower than
24 inches prevented sampling from 24 — 30 inches at 17 grid locations (M25, M33, P33, R33, 532, T24, T29,
U35, W22, W36, Y28, CC19, CC27, DD10, EE21, GG23 and GG24). Due to the presence of ponded rain
water at six locations (J32, J33, Q31, P31, S30 and S31) and soils too wet to access on foot but not
underwater at three locations (X21, X22 and DD08), sampling was performed by taking a 2-feet deep
scoop of material with an excavator bucket, dumping the material on dry ground, and then filling sample
jars. Four locations covered by stockpiled soil from the decommissioned intermediate dam were sampled

by excavating test pits and then filling sample jars with soil excavated from below the stockpiled fill (BB28,
131329, BB31 and 131332) Twenty-one sample locations were offset from the grid point location, as detailed
in Table 3.
The PLM evaluations were performed by RJ Lee Group, and the results are included in Attachment 3. PLM
results indicated a percentage of CCR ranging from not detected (ND) to 26 percent, with 97.5 percent of
sample results ranging from ND to 6 percent). The maximum allowable CCR percentage is 50 percent as
described in the Excavation Soil Sampling Plan, indicating that CCR removal has been achieved in
accordance with the plan. The results of a visual and laboratory soil classification of near -surface
materials presented in Table 2 indicate that CCR removal has been achieved in accordance with the plan.
Conclusions
CCR removal verification criteria have been satisfied in general accordance with Section 3.0 of the
Excavation Soil Sampling Plan, Riverbend Steam Station Rev. 2, December 2018, and in accordance with
the soil closure guidelines Duke Energy received from NCDEQ on November 4, 2016.

Wood,

Notes:
1. A positive number indicates that the CCR removal grade is higher than the estimated
bottom of CCR grade.
2. Sample locations with a-999.00 for elevation were located outside of the waste boundary
and did not have an estimated bottom of ash elevation.
References:
1. Estimated Bottom of CCR Elevations are from Drawing No. RVB_C901.016.004, entitled
"Estimated Bottom of Ash Excavation Grades - Overview", dated 9/18/2018.
2. Post-CCR Removal Elevations are from topographic mapping by LDSI based on 3/7/2019
aerial photography, modified to remove stockpiles in the area of grid Q-U 24-29 and Z-AA 30-
34. These stockpiles of clean material were placed after bottom of ash was encountered.
