Subject: Underground Injection Permit Application

Belews Creek Steam Station

Mr. Michael Rogers,
On behalf of Duke Energy Carolinas, LLC (Duke Energy), AECOM Technical Services of North
Carolina Inc. (AECOM) is submitting the attached Application for a Permit to Construct or
Operate Injection Wells — Injection Well Type "Other" (UIC Permit) to install and operate a clean
water infiltration system as part of a proposed groundwater remediation system for the Duke
Energy Belews Creek Steam Station (BCSS). The groundwater remediation system intends to
accelerate the corrective action process to meet applicable groundwater standards. The UIC
permit application and associated attachments are provided for approval to install and use 74
clean water infiltration wells as part of groundwater remediation activities at the Belews Creek
Steam Station.
Background
A Consent Order (CO) that specifies obligations related to the closure of the coal ash
impoundment and groundwater corrective action at the Belews Creek Steam Station (Belews
Creek) was signed on February 5, 2020 to address a Settlement Agreement between Duke
Energy, the North Carolina Department of Environmental Quality (NCDEQ) and relevant
community groups. The CO requires constituents of interest (COls) attributable to the Belews
Creek ash basin be remediated to concentrations less than the North Carolina Administrative
Code, Title 15A, Subchapter 02L, Groundwater Classification and Standards (02L) by December
31, 2029 at or beyond the defined Geographic Limitation. COls identified in the Corrective Action
Plan (CAP) Update (Synterra, 2019) include arsenic, beryllium, boron, chloride, cobalt, iron,
lithium, manganese, strontium, thallium, and total dissolved solids. The "Geographic Limitation"
is defined in the CO as 500 feet from the ash basin waste boundary, at the property boundary,
or the boundary of a water body, whichever is closer.
Groundwater flow and transport modeling was used to evaluate and select a groundwater
remedial alternative in the CAP Update developed by Synterra Corporation and submitted to
NCDEQ on December 31, 2019. Following the acquisition of a 2.67-acre parcel within the
Geographic Limitation by Duke in March 2020, the groundwater flow and transport model and
selected remedial action were updated to their current iterations as detailed in the Consent Order
Provision submitted to NCDEQ on April 7, 2019. The current schedule detailed in the CO
BUILDING A SMARTER ENERGY FUTURE"'
June 19, 2020
Page 2
assumes that groundwater remedial activities at the Belews Creek Steam Station will begin in
2020.
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 extend from the saprolite
into the bedrock flow zone.
Groundwater Remediation Activities
The groundwater remedial action selected in the CAP Update includes a groundwater
remediation system that consists of a combination of groundwater extraction and clean water
infiltration. The proposed groundwater remediation system will be installed in phases, beginning
with a pilot -scale system (Phase 1) to facilitate refinement of the final system design and
implementation. Following Phase 1 implementation and evaluation, the full-scale system will be
designed and installed (Phase 2). The groundwater treatment system is designed to maximize
pore volume exchange (i.e. groundwater flushing) and establish groundwater flow control and
capture in areas downgradient of the Belews Creek Steam Station ash basin. Phase 1 of the
groundwater extraction system will include 23 groundwater extraction wells that will utilize down -
well submersible pumps to convey groundwater to an on -site treatment system prior to
discharging to a Nation Pollutant Discharge Elimination System (NPDES) permitted outfall.
Phase 1 of the clean water infiltration system will consist of a water treatment system to treat
surface water from Belews Lake delivered to the treatment system from the Steam Station fire
service water main. Compounds added to source water will be consumed during the treatment
process and will not be a component of the final infiltration water. After treatment, clean water
will be conveyed to 23 clean water infiltration wells for low-pressure (less than five pounds per
inch [psi]) delivery to groundwater. The anticipated total flow rates during Phase 1 from the
extraction wells and into the infiltration wells are approximately 37 gpm and 37 gpm,
respectively, based on modeling results. The proposed pilot test extraction and clean water
infiltration well locations were selected to ensure that clean infiltration water will be captured by
the pilot test extraction well network.
Phase 2 of the groundwater extraction system will include the installation of approximately 76
additional groundwater extraction wells and 51 additional clean water infiltration wells. During
Phase 2, the anticipated total flow rates from the extraction wells and into the infiltration wells
are approximately 130 gpm and 120 gpm, respectively, based on modeling results. Therefore,
expected extraction rates are greater than expected infiltration rates.
Based on the distribution of COI and the vertical hydraulic connection through the saprolite,
transition, and bedrock zones, Duke Energy is proposing to install the infiltration wells with well
screen and/or sand pack material across all three zones. Given the interconnectivity of the
hydrostratigraphic zones, Duke Energy is requesting a variance from 15A NCAC 02C .0225
North Carolina Well Construction Standards in accordance with 15A NCAC 02C .0241 based on
the following:
• Construction of the infiltration wells with screens across the three water -bearing units will
allow for more effective remediation of groundwater.
June 19, 2020
Page 3
• 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.
• The proposed well construction is not expected to generate a potential risk to human
health or groundwater.
• Water supply wells are not located within 500 feet of the proposed extraction wells.
The Application for a Permit to Construct or Operate Injection Well(s) 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. Andrew Shull (919.546.2104) or Mr. Scott
Davies (980.373.6563) with any questions or concerns regarding this application.

Clean Water Infiltration System Operating Design
UIC Permit Application
Belews Creek Steam Station
Belews Creek, North Carolina
The proposed clean water infiltration system will include a pre -infiltration water treatment system, seventy-
four (74) vertical clean water infiltration wells, conveyance piping, pumps, and associated equipment and
instrumentation. Water used for the clean water infiltration system will be conveyed from the Belews Creek
Steam Station fire service water main to the water treatment system. Water for the fire service water main
is derived from Belews Lake (see Figure D-2). Duplex pumps will be utilized to convey water from the fire
service water main to the infiltration water treatment system. Following the receipt of analytical results from
the Belews Lake surface water samples, AECOM will design the infiltration water treatment system to treat
surface water prior to low-pressure introduction to groundwater through the infiltration well network. AECOM
anticipates the infiltration water treatment system could possibly require the following process treatment
components:
• Initial Filtration (e.g.: Disposable cartridge filters)
• Chemical and mechanical precipitation (e.g.: Sodium hydroxide')
• Disinfection (e.g.: Ultraviolet light)
• pH adjustment (e.g.: Sulfuric acid', acetic acid')
• Final filtration prior to discharge (e.g.: Disposable cartridge filters)
Compounds added to source water will be consumed during the treatment process and will not be a
component of the final infiltration water. Samples will be collected to evaluate treatment system
effectiveness prior to infiltration water delivery to groundwater. Parallel treatment processes will be utilized
to facilitate infiltration system operation and maintenance and help achieve optimal runtime and
performance. Individual system components (turbine pumps, equalization tanks, modular treatment system
units, and transfer pumps) will be capable of operating singularly or in parallel to achieve maximum
infiltration water production capacity and system redundancy. The infiltration well system controls and
monitoring equipment will be housed in an enclosed structure to prevent exposure to prevailing weather
conditions. A conceptual process flow diagram for the groundwater treatment system is included as Figure
C-1. In the event of a system malfunction or power loss in any part of the infiltration water treatment or
pumping systems, the system control logic will have redundant safeguards designed to shut off water
conveyance to infiltration treatment system and clean water infiltration wells to prevent untreated surface
water from entering the infiltration wells.
Following treatment, infiltration water will be pumped to parallel equalization tanks, each capable of
handling the total system flow in the event maintenance is required on either tank. Clean infiltration water
will then be conveyed to an infiltration water control and distribution system building that will house the
manifold legs of each clean water infiltration well. Manifold legs will include a solenoid shutoff valve, a flow
control valve, and flow and pressure transmitters. The transmitters will communicate with the system PLC
to monitor clean water infiltration system operation. HDPE piping will then convey infiltration water from the
manifold to each infiltration well (well schematic included in Attachment B). Table C-1 includes the design
injection rate, pressure, and water temperature at each clean water infiltration well. On/off valves in the
system will normally closed (power to open) to ensure infiltration line shutdown in the event of a power
failure.

water supply wells, septic systems, or other sources
of contamination located within 250 feet of the proposed
clean water infiltration wells. Multiple monitoring wells
and surface water bodies are located within 250 feet of
the proposed clean water infiltration wells.
