H.F.Lee Energy Complex-Duke Energy Progress,LLC SynTerra
1.0 INTRODUCTION
On March 28 and 29, 2019,Judd Mahan (NC L.G. #2026) of SynTerra inspected the H.F.
Lee Energy Complex (H.F. Lee or Site) property for existing and potential new seeps.
No changes to seep status were observed during this inspection. Inspection activities
were performed in accordance with North Carolina Environmental Management
Commission (EMC) Special Order by Consent WQ #S18-006. That Special Order by
Consent(SOC) describes inspection requirements as follows:
Duke Energy shall conduct annual comprehensive surveys of areas down gradient of ash
basins, the Lay of Land Area (LOLA) and the cooling pond, identifying new seeps, and
documenting the physical characteristics of previously documented seeps. All
examinations of seeps must include identification of seeps by approximate latitude and
longitude and date-stamped digital photographs of their appearance. A report
summarizing the findings of the surveys, including a section analyzing the effect
decanting of the basin(s) has on seep flows, accompanied by copies of the photographs
noted above ("Annual Seep Report"), shall be submitted to DWR in conjunction with
submittal of the April 30 quarterly report noted in 2(b)(3) above. This Annual Seep
Report must list any seep that has been dispositioned (as described below) during the
previous year, including an analysis of the manner of disposition.
All locations listed in Table 1 of the SOC were observed and documented with
photographs during the inspection.
General observations include:
• No previously unidentified seeps were observed during the inspection.
• No notable changes to seep status were observed during the inspection.
• The decanting target for the active ash basin was reached in November 2018.
1.1 Inspection Details
The weather was clear before and during the inspection. Temperatures ranged from
approximately 45 to 75 degrees Fahrenheit (F). No rain occurred during the inspection
according to the on-Site rain gage. The on-Site rain gauge had the following results on
the three days before the inspection: 0.28 inches (March 25), 0.12 inches (March 26), and
0.00 inches (March 27).
The inspector reviewed previous seep inspection reports and the weekly dam safety
inspection reports for each ash basin. Sharat Gollamudi (Duke Energy system owner)
conducted the ash basin dam safety inspections and prepared the reports.
Page 1-1

2019 Annual Seep Report April 2020
H.F.Lee Energy Complex-Duke Energy Progress,LLC SynTerra
Mr. Gollamudi and Mr. Chris Hallman (Duke Energy Subject Matter Expert) were
interviewed about recent rainfall amounts, recent construction/stabilization projects
associated with the ash basins, and general Site conditions in and around the ash basins.
Observations from the dam safety inspection reports were consistent with observations
made during the SOC inspections.
The inspection included observations in the following areas (Figure 1):
• Along the shore of the Neuse River and Halfmile Branch
• Areas along and downgradient of the ash basin dam
• Drainage features associated with the ash basins
Seep locations and inspection areas are shown on Figure 1. Observations noted during
the inspection are summarized on Table 1. Photographs taken of each seep location
during the inspection are included in Appendix A.

2.0 FINDINGS
2.1 General Observations
Inspection observations are shown for each seep in Table 1. Details include:
• No new seeps were observed during the inspection.
• No previously unidentified or unreported pipes were observed during
inspection.
• The Neuse River stage was relatively high. The nearby United States Geological
Survey (USGS) rain gauge station (02089000) reported the Neuse River ranged
from approximately 11.8 feet to 10.6 feet and was falling over the two days of
inspection.
• The Neuse River water level was high enough to back up into seep areas
including: CPS-1 through CPS-7, CPS-20, S-3A, S-9, and S-18.
• Saturated ground and standing water were observed as evidence of recent
precipitation. Existing ditches and depressions along the perimeter of the basins
were generally observed to hold standing water.
2.2 Effects of Decanting
Decanting of the active ash basin at H.F. Lee commenced in April 2016 and was
completed in November 2018. Future dewatering of ash pore water in the active ash
basin is expected to substantially reduce or eliminate the seeps.
2.3 Changes to Seep Status
Mr.Mahan inspected each seep to evaluate whether it met requirements to be
dispositioned in accordance with the SOC. The requirements for dispositioning a seep
are as follows:
For purposes of this Special Order, "dispositioned" includes the following: (1) the seep is
dry for at least three consecutive quarters; (2) the seep does not constitute, and does not
flow to, waters of the State or Waters of the United States for three consecutive quarters;
(3) the seep is no longer impacted by flow from any coal ash basin as determined by the
Director of DWR in accord with applicable law and best professional judgment; or (4) the
seep has been otherwise eliminated (e.g., through an engineering solution). If a seep that
has been dispositioned through drying up reappears in any subsequent survey, such a
seep will no longer be deemed dispositioned and can be subsequently re-dispositioned as
specified above.
No changes to seep status were observed during this inspection.
