Application for Permit to Construct Recovery (Extraction) Wells
Duke Energy Carolinas, LLC
Belews Creek Steam Station
Belews Creek, NC 27009
Dear Mr. Gonsiewski:
Duke Energy Carolinas, LLC (Duke Energy), is submitting the enclosed application package to obtain a
permit to install 49 recovery (extraction, EX) wells as part of the full-scale groundwater remediation
system at the Belews Creek Steam Station (Site), located in Belews Creek, North Carolina (Figure 1). As
part of a pilot study, twenty-three groundwater extractions wells were installed under well permit
WV0400056 in the Fall of 2020.
As detailed in the Corrective Action Plan (CAP) Update Report (SynTerra, 2019) and the Demonstration
of 02L Compliance for the Belews Creek Ash Basin technical memorandum (Tech Memo) (SynTerra,
2020), Duke Energy is implementing a multi -component CAP, including source control through excavation
of the Ash Basin and capping of existing on -site landfills, groundwater corrective action, and an
effectiveness monitoring plan to track progress during and after groundwater corrective action. The
groundwater CAP includes provisions for a robust groundwater remediation program that consists of
using groundwater extraction wells combined with clean water infiltration wells and associated treatment
to address constituents of interest (COI) concentrations in groundwater greater than applicable standards
at or beyond the Geographic Limitation of the Ash Basin.
As discussed in the CAP Update (SynTerra 2019), groundwater in the area of the Site occurs in three
interconnected hydrostratigraphic zones:
• The shallow flow zone in soils and saprolite (saprolite zone),
• The transition flow zone (referred to as "deep" in some previous reports); and
• The bedrock flow zone.
Groundwater flow and transport modeling suggest site -related COI are present from the saprolite into the
bedrock flow zone. Based on the distribution of COI and the vertical hydraulic connection through the
saprolite, transition, and bedrock zones, Duke Energy is proposing to install 49 extraction wells with well
screen and/or sand pack across all three zones (Table 1). Figures 2 and 3 illustrate the approximate

locations of the proposed extraction wells. Final locations will be determined in the field during
construction and surveyed by a licensed surveyor.
Given the interconnectivity of the hydrostratigraphic zones and consistent with the pilot study well
construction (permit WV0400056), Duke Energy is requesting a variance from 15A NCAC 02C .0108
North Carolina Well Construction Standards in accordance with 15A NCAC 02C .0105 based on the
following:
• Construction of extraction wells with screens across the three water -bearing units will allow for
more effective remediation of groundwater.
• Site -related COI are present in groundwater in all three zones.
• Corrective action to address these COI in groundwater is also proposed in all three zones.
• Extraction of groundwater provides the necessary hydraulic connection between the COI -
affected groundwater zones and the proposed clean water infiltration, which targets the saprolite
and transition zones.
• The proposed well construction is not expected to generate a potential risk to human health or
groundwater.
• Due to expected low well yield in some areas (less than two gallons per minute), constructing
recovery wells to extract water from a specific water -bearing unit would not provide sufficient well
yield to effectively remediate groundwater at the site.
• Water supply wells are not located within 500 feet of the proposed extraction wells.
The Application for Permit to Construct a Recovery Well System is attached, as well as additional
supporting information provided for your review and approval. We appreciate the NCDEQ's timely review
of this submittal package as we proactively implement the groundwater remediation strategy for this Site.
Please contact Mr. Scott Davies (980.373.6563) with any questions or concerns regarding this
application.
Sincerely,
Scott E. Davies, P.G.
