Subject: Application for Permit to Construct Recovery (Extraction) Wells
Dear Mr. Rice:
526 South Church St
Mail Code EC13K
Charlotte, NC 28202
Duke Energy Progress, LLC (Duke Energy), is submitting the enclosed application package to
obtain a permit to install 41 recovery (extraction) wells as part of the pilot test phase of a
proposed groundwater remediation system at the Roxboro Steam Electric Plant (Site), located
in Semora, North Carolina.
As detailed in the Corrective Action Plan (CAP) Update Report (SynTerra 2019)1, Duke Energy
is implementing a multi -component CAP, including source control through excavation of the ash
basins 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 and treatment to address constituents of interest
(COI) concentrations in groundwater greater than applicable standards at or beyond the
Geographic Limitation of East Ash Basin, and a combination of groundwater extraction and
clean water infiltration at the Gypsum Storage Area (GSA) and Dry Fly Ash Handling Area
(DFAHA).
As discussed in the CAP Update (SynTerra 2019), groundwater in the area of the Site is
presented 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 in the bedrock
flow zone. Based on the distribution of COI, Duke Energy is proposing to install select extraction
wells (EX-19 through EX-59) as individual extraction wells, screened in the bedrock zone.
