Subject: Consent Order Provision
Demonstration of 02L Compliance for the Ash Basin by December 31, 2029
Belews Creek Steam Station
Stokes County, North Carolina
Dear Ms. Holman:
A Consent Order (CO) that specifies obligations related to the closure of coal ash
impoundments and groundwater corrective action at six Duke Energy coal combustion sites in
North Carolina, including Belews Creek Steam Station (Belews Creek) was signed on February
5, 2020. The CO requires 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
Geographic Limitation. 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.
The attached memorandum prepared by SynTerra Corporation on behalf of Duke Energy,
addresses a provision of Paragraph 27 of the CO. The memorandum provides a technical
demonstration that groundwater constituents of interest (COls) attributable to the coal ash basin
can be remediated to be concentrations less than 02L standards by December 31, 2029.
The Belews Creek Corrective Action Plan Update (SynTerra, 2019) provided three groundwater
remedial alternatives. Groundwater flow and transport model simulations used in those
alternatives indicated that the earliest the Belews Creek ash basin could be in compliance with
02L standards is approximately 10 to 13 years after groundwater operations begin. To comply
with Paragraph 27 of the CO, SynTerra developed a fourth remedial alternative that takes an
accelerated approach to the remediation of affected groundwater at or beyond the geographic
limitation.
Corrective action modeling for this technical demonstration for Belews Creek assumes that
groundwater remediation activities will begin in 2020 and compliance will be achieved by
December 31, 2029. This also includes the acquisition of a triangular -shaped parcel,
approximately 2.67 acres (i.e. Parcel A), located northwest of the ash basin which extends the
geographic limitation by approximately 300 feet from its former position.

Subject: Demonstration of 02L Compliance for the Belews Creek Ash Basin by
December 31, 2029
SynTerra prepared this technical memorandum for Duke Energy to address a provision
of Paragraph 27 of the Consent Order, dated February 5, 2020, regarding coal ash
management in North Carolina. Specifically, this memorandum provides a technical
demonstration that groundwater constituents of interest (COIs) attributable to the coal
ash basin at the Belews Creek Steam Station (BCSS, Site) can be remediated to be
concentrations less than North Carolina Administrative Code, Title 15A, Subchapter
02L, Groundwater Classification and Standards (02L) by December 31, 2029. This
demonstration was performed using multiple lines of evidence including:
• Extensive data collected at the Site and analyzed
• A robust groundwater flow and transport model that simulates groundwater
remediation alternatives for meeting the 2029 timeframe
Details regarding this demonstration are presented as follow.
Background
Duke Energy, the North Carolina Department of Environmental Quality (NCDEQ), and
11 community groups entered into a Settlement Agreement (SA) on December 31, 2019.
A Consent Order (CO) to address the SA was finalized on February 5, 2020 (Attachment
A). The CO specifies obligations related to the closure of coal ash impoundments at
seven of Duke Energy's North Carolina coal combustion sites. The CO also specifies
obligations related to groundwater corrective action plans (CAPs) pertaining to the
seven sites, including BCSS in Belews Creek, Stokes County, North Carolina.
The BCSS CAP Update (SynTerra, 2019) provides three groundwater remedial
alternatives. Groundwater flow and transport model simulations used in those
alternatives indicate that the earliest the BCSS ash basin could be in compliance with
02L standards is approximately 10 to 13 years after groundwater remediation
operations begin, potentially after the December 31, 2029 date included in Paragraph 30
of the CO.

Duke Energy Carolinas, LLC - Belews Creek Steam Station SynTerra
SynTerra has addressed the demonstration required in Paragraph 27 of the CO by
developing a fourth remedial alternative that takes an accelerated approach to the
remediation of affected groundwater at or beyond the "geographic limitation' (i.e.
equivalent to 500 feet from the ash basin waste boundary, as described in Paragraph 75
of the CO, Attachment A). The fourth alternative establishes December 31, 2029, as the
date by which the Site would be in compliance with 02L standards. This demonstration
is submitted in accordance with the schedule requirement (on or before May 4, 2020)
included in Paragraph 27 of the CO.
The demonstration presented below follows the same format as the remedial
alternatives presented in the BCSS CAP Update (SynTerra, 2019), with applicable
section references, beginning with CAP Content Section 6.D.a as included in the CAP
content guidance issued by NCDEQ on September 10, 2019. In this manner, the
demonstration presented below is consistent with the methodology used to evaluate
remedial options in the CAP Update and in accordance with NCDEQ's preferred
format.
Remedial Alternative 4 - Accelerated Groundwater Extraction
Combined with Clean -Water Infiltration and Treatment
(CAP Content Section 6.D.a)
This accelerated remedial alternative consists of groundwater extraction combined with
clean -water infiltration and treatment for the areas north and northwest of the ash
basin. This alternative provides an effective combination of technology for groundwater
remediation at or beyond the "geographic limitation".
Under this alternative, compliance with 02L can be achieved within approximately 9
years after system operation begins. The lesser timeframe, relative to remedial
alternatives presented in the CAP Update (SynTerra, 2019), for compliance is achievable
under the following assumptions:
1. The "geographic limitation", as described in Paragraph 75 of the CO
(Attachment A), is equivalent to 500 feet from the ash basin waste boundary, as
shown on the most recent National Pollutant Discharge Elimination System
(NPDES) permit. Per the most the recent NPDES permit, this geographic
limitation is equivalent to the "compliance boundary";
2. Duke Energy acquired a triangular -shaped parcel, approximately 2.67 acres (i.e.
Parcel A), located northwest of the ash basin on March 4, 2020. Duke Energy's
ownership of the parcel locally extends a small section (less than 500 feet) of the
Page 2

Belews Creek Ash Basin by December 31, 2029 March 23, 2020

geographic limitation by approximately 300 feet from its former position (see
"modified geographic limitation" in Figure 1).
Problem Statement and Remediation Goals
(CAP Content Section 6.D.a.i)
A limited number of CCR constituents in groundwater associated with the BCSS ash
basin and the closed Pine Hall Road (PHR) Landfill occur at or beyond the geographic
limitation to the north and northwest of the ash basin at concentrations detected greater
than applicable 02L standards, Interim Maximum Allowable Concentrations (IMACs),
or background values, whichever is greater. Groundwater remediation goals are to
restore groundwater quality at or beyond the geographic limitation by returning
constituent concentrations to acceptable concentrations (02L, IMAC, or background,
whichever is greater), or as closely thereto as is economically and technologically
feasible consistent with 15A NCAC 02L .0106(a). In the future, alternative standards
may be proposed as allowed under 02L .0106(k). This approach is considered
reasonable given the documented lack of human health risk or ecological risk at the Site
(CAP Content Section 6.1).a.i.2).
As discussed in the CAP Update (SynTerra, 2019), the groundwater constituents to be
addressed by corrective action are arsenic, beryllium, boron, chloride, cobalt, iron,
lithium, manganese, strontium, thallium, and total dissolved solids (TDS) (CAP Content
Section 6.D.a.i.1). These are the constituents that indicate a discernable plume associated
with the source area.
The conceptual model and predictive modeling discussions summarize the foundations
for development of the accelerated groundwater extraction combined with clean -water
infiltration and treatment remedial alternative presented herein. The remedial
technology and the general area targeted for groundwater remediation for this
accelerated alternative are equivalent to CAP Update (SynTerra, 2019) "Remedial
Alternative 3 - Groundwater Extraction Combined with Clean -Water Infiltration and
Treatment." Therefore, discussion of the conceptual site model, flow and transport
modeling, and geochemical modeling presented in the CAP Update are applicable to
the accelerated remedial alternative presented herein. The BCSS Conceptual Site Model
(CSM) is discussed in Section 5.0 of the CAP Update; the Belews Creek flow and
transport model report is presented in CAP Update Appendix G (SynTerra, 2019); and
the Belews Creek geochemical model report is presented in CAP Update Appendix H
(SynTerra, 2019).

Conceptual Model — Corrective Action Design to Demonstrate
Groundwater Remediation Objectives Can be Achieved by
December 31, 2029
(CAP Content Section 6.D.a.ii)
The applicable remedial design components that comprise this demonstration include:
• 52 extraction wells to the north and northwest of the ash basin
• 84 clean -water infiltration wells north and northwest of the ash basin
• Associated pumps, piping, and control systems
• An infiltration water intake structure and distribution piping
• Infiltration and discharge piping and structure
• Applicable water treatment system(s) to comply with permit requirements
The proposed design and well locations are shown on Figure 1. The flow and transport
model predicts a total groundwater infiltration system flow rate of approximately 118
gallons per minute (gpm) would be required and a total groundwater extraction system
flow rate of approximately 85 gpm would be required. Post -decanting, the existing 10
interim action extraction wells installed in the area northwest of the ash basin are
predicted to remove about 2.5 gpm. The continued operation of the interim action
extraction wells is not included in this remedial alternative. The number of extraction
and clean -water infiltration wells is estimated based on flow and transport modeling
results. A general summary of the systems anticipated number of groundwater
extraction wells and clean -water infiltration wells per flow zone — with corresponding
depth ranges, and with system flow rate and operation assumptions — is included in
Table 1.
The system's design includes approximately half of the extraction wells completed into
bedrock to allow full drawdown within the transition zone. Depths of bedrock
extraction wells, dependent on the transition zone and bedrock contact depth, range
from 60 feet below ground surface (bgs) to approximately 180 feet bgs in the design.
Based on the CSM and flow and transport modeling results, both presented in the CAP
Update (SynTerra, 2019), groundwater affected by the ash basin is hydraulically
controlled within the topographic drainage basin downgradient of the ash basin, with
the exception of the area to the northwest of the dam.
The distribution of conservative [non -reactive, greatly mobile due to low partition
coefficient (Ka) values] constituents (e.g. boron, chloride, TDS) represents the maximum
Page 4

Demonstration of 02L Compliance for the
Belews Creek Ash Basin by December 31, 2029 March 23, 2020
Duke Energy Carolinas, LLC - Belews Creek Steam Station SynTerra
horizontal and vertical extent of groundwater affected by the ash basin. The area that is
the focus of corrective action is determined by the maximum horizontal and vertical
extent of groundwater affected by the ash basin at or beyond the geographic limitation.
Boron is relatively more soluble and mobile in groundwater compared to other CCR
constituents (Chu, 2017). At Belews Creek, the distribution of boron concentrations
greater than the 02L boron groundwater standard of 700 µg/L represents the maximum
horizontal and vertical extent of groundwater affected by the ash basin. Under 2019 pre -
decanting conditions, boron concentrations, along with other conservative constituent
concentrations (CAP Update; SynTerra, 2019), decrease to less than the 02L
groundwater standards within 500 to 750 feet beyond the ash basin waste boundary, or
less than 250 feet beyond the modified geographic limitation (Figure 2 through
Figure 4).
Due to constituent geochemical characteristics and Site geochemical and hydrogeologic
conditions, additional constituent concentrations — identified as being greater than
their respective groundwater regulatory standards or background values, and
associated with affected groundwater migration from the ash basin — have generally
not migrated, horizontally or vertically, appreciably from the source area (CAP Update,
SynTerra 2019). Non -conservative and variable constituents have smaller, and generally
isolated, plume geometries that are confined within the extent of the 02L boron plume
at the Site, because of their high Ka values and reactivity, which reduce their mobility.
Focusing remedial action on addressing conservative constituents would also address
non -conservative and variably reactive constituents for the following reasons:
1. The area of conservative constituent distribution at or beyond the geographic
limitation is greater than the area of non -conservative and variably reactive
constituent distribution.
2. Mobilized, non -conservative, and variably reactive constituents follow the
same groundwater flow path.
3. Non -conservative and variably reactive constituents are more reactive and
can effectively attenuate by natural attenuation mechanisms, other than
physical attenuation mechanisms (e.g. sorption, precipitation, and ion
exchange). Natural attenuation helps stabilize control of non -conservative
and variably reactive constituents.
Groundwater flushing involves the infiltration of clean water into groundwater to
accelerate flushing of targeted constituents. The introduction of a clean water into
groundwater enhances physical groundwater flow by increasing the hydraulic gradient
Page 5

Belews Creek Ash Basin by December 31, 2029 March 23, 2020
Duke Energy Carolinas, LLC - Belews Creek Steam Station SynTerra
between the point of infiltration and the point of extraction or discharge. Infiltration of
clean water into the groundwater system can enhance groundwater flushing at
locations with limited natural recharge or low permeability. Constituents mobilized by
flushing would be captured by an extraction well or could naturally attenuate by
enhanced (from active infiltration and flushing) physical natural attenuation
mechanisms such as advection, dispersion, and molecular diffusion.
Based on water quality and implementation access and feasibility, water used for clean -
water infiltration would be obtained from the Dan River. It is expected that infiltration
water would be treated for pH and suspended solids using pH adjustment and
flocculation technology.
Extracted groundwater would also be treated and discharged through the existing
NPDES Internal Outfall 006A and Outfall 006 locations based on currently available
groundwater data and the current permit. Initially, the groundwater would be treated
by pH adjustment and flocculation in the system used to treat the water from decanting
and dewatering the ash basin. Post -decanting and dewatering of the ash basin provides
an intervening period, where modifications to the decanting/dewatering treatment
system or alternatives, including beneficial reuse, would be considered. If necessary, a
modified treatment method would be selected based on the quantity and quality of the
extracted groundwater. A preliminary summary of groundwater data and current
discharge permit limits is presented in the Section 6.0 of the CAP Update (SynTerra,
2019).
Preliminary calculations pertaining to the remedial alternative piping design (e.g. pipe
sizing, pressures, flow, friction losses, etc.) and graphically represented conceptual
extraction and clean -water infiltration well network layouts are included in
Attachment B.
Predictive Modeling
(CAP Content Section 6.D.a.iii)
A clean -water infiltration and groundwater extraction remediation system would result
in localized groundwater flow control and increase the rate of mass removal. While low
permeability might still limit flow in areas, the additional volume of groundwater
created by clean -water infiltration could enhance natural recharge and permeability,
increasing the effectiveness of flushing the system and reducing constituent mass.
The flow and transport simulated the total groundwater extraction system flow rate to
be 85 gpm, with an average flow rate per extraction well of approximately 1.6 gpm.
Extraction well efficiency is assumed to be 50 percent. The flow and transport simulated
Page 6

Demonstration of 02L Compliance for the
Belews Creek Ash Basin by December 31, 2029 March 23, 2020
Duke Energy Carolinas, LLC - Belews Creek Steam Station SynTerra
the total clean -water infiltration system flow rate to be 118 gpm, with an average flow
rate per infiltration well of approximately 1.4 gpm. Infiltration well efficiency is
assumed to be 25 percent. Modeled groundwater extraction well details are provided in
Table 2. Modeled clean -water infiltration well details are provided in Table 3.
The flow and transport model predicts the maximum extent of the boron plume, at any
point in time, would be approximately 800 feet beyond the modified geographic
limitation. This maximum extent of the boron plume occurs northwest of the ash basin
during the timeframe for system startup and operation (i.e. the earliest timeframe
modeled; Figure 5). Flow and transport simulations demonstrate that boron
concentrations in groundwater can meet the 02L boron standard of 700 µg/L at the
modified geographic limitation within approximately 9 years after system startup and
operation (Figure 5).
The simulated time it would take to achieve compliance is likely conservative because
the area targeted for groundwater remediation northwest of the ash basin, particularly
in the area of the 2.67 acres where no data is currently available, has been calibrated in
the flow and transport model with a low hydraulic conductivity zone. The area was
calibrated in order to simulate boron transport in the transition zone and bedrock that
matches empirical Site data.
The geochemical modeling report (CAP Update Appendix H) provides applicable
detailed Site predictions, descriptions, and explanations of the effects of clean -water
infiltration and groundwater extraction. Discussion of flow and transport detailed Site
predictions, description, explanations of the effect of clean -water infiltration and
groundwater extraction are provided below.
Flow and Transport Predictive Simulation — Closure -by -
Excavation with Accelerated Active Remediation
The closure -by -excavation design involves excavation of the ash in the ash basin,
with construction of an on -Site landfill.
Groundwater remediation such that compliance with the 02L groundwater rule
is achieved by December 31, 2029, is simulated using the groundwater flow field
of the interim model with the ash, after the ash basin is decanted. Completion of
ash basin decanting, which began on March 27, 2019, is scheduled to be
completed by September 2020. Therefore, it is assumed that the construction of
the remedial system outside of the ash basin is completed by the end of year
2020. It is assumed that constituent concentrations are not changed significantly
during ash basin decanting. The transport simulation using the flow field of the
Page 7

Demonstration of 02L Compliance for the
Belews Creek Ash Basin by December 31, 2029 March 23, 2020
Duke Energy Carolinas, LLC - Belews Creek Steam Station SynTerra
interim model continues to run until compliance with the 02L groundwater rule
is achieved (approximately 9 years after ash basin decanting is completed).
Because compliance with 02L is achieved before the completion of ash basin
closure -by -excavation (assumed to be approximately 16 years after ash basin
decanting is completed), the remediation system is not included in the
excavation model or simulated using the resulting flow field in the excavation
model.
The groundwater remediation primarily occurs northwest of the ash basin. The
remedial system considered consists of 52 extraction wells pumping a total
extraction rate of 85 gpm (Table 2). Eighty-four (84) clean -water infiltration wells
are considered to introduce a total of 118 gpm of clean water to the system
(Table 3).
The extraction wells are simulated using a vertical series of MODFLOW DRAIN
points. The DRAIN bottom elevations are set to the center of the gridblock
containing the drain. This simulates a condition where the water is being
pumped out of the well casing to maintain a water level near the bottom of the
well. The DRAIN conductance values are estimated by considering radial flow
to a well, which follows the Anderson and Woessner (1992) approach. For a
horizontal hydraulic conductivity of K, a well radius of rW, and horizontal and
vertical grid spacing of Ax and Az, the DRAIN conductance for a gridblock is
computed as:
C=
2;TKAz
In 0.208Ax
r
W
The conductance value is reduced by 50 percent to account for well skin effects.
Clean -water infiltration wells are treated similarly, using the General Head
Boundary (GHB) condition in MODFLOW, with a conductance calculated the
same way, but with a reduction of 75 percent to account for well clogging. The
clean -water infiltration well heads are set to 10 feet above the ground surface.
Figure 5 shows the maximum boron distribution in all non -ash layers at 4- to 5-
year intervals starting after the ash basin has been decanted. The remediation
system achieves 02L compliance 9 years after system startup and operation,
demonstrating that compliance by December 31, 2029, is achievable under the
assumptions and conditions presented in this technical memorandum (Figure 5).

Belews Creek Ash Basin by December 31, 2029 March 23, 2020
Duke Energy Carolinas, LLC - Belews Creek Steam Station SynTerra
Northwest of the ash basin in the transition zone and shallow bedrock, there are
low hydraulic conductivities zones in the model where the boron persists the
longest. Northwest of the ash basin, a groundwater divide intersects these low
hydraulic conductivity zones in the model, which reduces groundwater
velocities and contributes to the challenge of achieving 02L compliance in an
accelerated timeframe.
Based on conclusions from the Updated Groundwater Flow and Transport
Modeling Report (CAP Update Appendix G), distributions of chloride and total
dissolved solids in groundwater are similar to boron distributions, and active
remediation approaches appear equally effective in reducing the areas of 02L
chloride (250 mg/L) and TDS (500 mg/L) within a similar timeframe.
Summary
Based on groundwater modeling simulations performed using Site -specific data, and
assumptions stated herein, this technical analysis demonstrates that 02L groundwater
compliance can be met at the BCSS by December 31, 2029.

CONSENT ORDER
Plaintiff, the State of North Carolina ex rel. North Carolina Department of Environmental
Quality ("DEQ"), Division of Water Resources, Plaintiff -Intervenors, Roanoke River Basin
Association, Sierra Club, Catawba Riverkeeper Foundation, Inc., Appalachian Voices,
MountainTrue, and Waterkeeper Alliance ("Community Groups"), and Defendants, Duke Energy
Carolinas LLC and Duke Energy Progress LLC ("Duke Energy") (collectively the "Parties"),
hereby consent to the entry of this Consent Order in order to resolve the matters in controversy
between them.
The Honorable Paul Ridgeway, Senior Resident Superior Court Judge, is presiding over
these matters pursuant to designation under Rule 2.1 of the General Rules of Practice. The Court
makes, and the Parties hereby stipulate to, the following findings of fact and conclusions of law.
Findings of Fact and Conclusions of Law
1. These actions were brought by the State of North Carolina upon the relation of the
Secretary of DEQ, the State agency established pursuant to N.C. Gen. Stat. § 143B-
279.1 et seq., and vested with the statutory authority to enforce the State's
environmental protection laws, including laws enacted to protect the water quality of
the State. The Division of Water Resources ("DWR") is a division within DEQ and all
actions taken by DWR are necessarily actions of DEQ.
2. This Court has jurisdiction over this action for injunctive relief for claims of existing
or threatened violations of the laws, rules, and regulations governing the protection of
the State's water resources pursuant to N.C. Gen. Stat: § § 7A-245 and 143-215.6C.
3. Venue is proper in Wake County for 13 CVS 11032 and Mecklenburg County for 13
CVS 14661 under N.C. Gen. Stat. §§ 1-79 and 143-215.6C.

4. Defendant, Duke Energy Carolinas, LLC ("Duke Energy Carolinas"), is a corporation
organized and existing under the laws of the State of North Carolina. Duke Energy
Carolinas owns, operates, or has operated the coal-fired steam station facilities'
addressed by DEQ's Mecklenburg County Complaint, Case No. 13 CVS 14661, and
this Order at the following locations: the Allen Steam Station ("Allen") in Gaston
County, Buck Steam Station ("Buck") in Rowan County,2 Cliffside Steam Station (now
referred to as the Rogers Energy Complex) ("Cliffside/Rogers") in Rutherford County
and Cleveland County, the Belews Creek Steam Station ("Belews Creek") in Stokes
County, and the Marshall Steam Station ("Marshall") in Catawba County.3
5. Defendant Duke Energy Progress, LLC ("Duke Energy Progress"), is a corporation
organized and existing under the laws of the State of North Carolina. Duke Energy
Progress owns or operates coal-fired steam station facilities addressed by DEQ's Wake
County Complaint, Case No. 13 CVS 11032, and this Order at the following locations:
Mayo Steam Electric Generating Plant ("Mayo") in Person County and the Roxboro
Steam Electric Generating Plant ("Roxboro") in Person County.4
1 The facilities listed in Paragraphs 4 and 5 may be referred to singularly as "Facility" and
collectively as "Facilities."
2 Buck has been selected by Duke Energy Carolinas, LLC as a beneficiation site pursuant to N.C.
Gen. Stat. § 130A-309.216(a). On December 16, 2016, the Community Groups dismissed their
Complaint in Intervention with prejudice as to Buck. As set forth below, this Consent Order
resolves the claims raised in DEQ's Complaint as to Buck.
3 In the Mecklenburg County Complaint, 13 CVS 14661, the Dan River Combined Cycle Station
is also included. Complaint at 2, ¶ 3. The Dan River Combined Cycle Station was addressed by
a prior order of the Court, and is not at issue in this Consent Judgment. Order Granting Motions
for Partial Summary Judgment, 13 CVS 14661 & 11032 (June 1, 2016) (the "Four Plant Order").
4 In the Wake County Complaint, 13 CVS 11032, the Cape Fear Steam Electric Generating Plant,
H.F. Lee Steam Electric Plant, Weatherspoon Steam Electric Plant and L.V. Sutton Electric Plant
were also included. Complaint at 2, ¶ 3. These facilities were addressed by prior orders of the
Court and are not at issue in this Order.

6. Plaintiff -Intervenors, the "Community Groups," are non-profit public interest
organizations whose mission and interests include advocating for the protection of
water quality for the health, protection, and enjoyment of their members. The
Community Groups were allowed to intervene in these actions with no objection from
DEQ. The Community Groups have stipulated that they assert no additional causes of
action in these proceedings beyond those asserted by DEQ.
7. DEQ filed these civil enforcement actions in August of 2013. As set forth in the
Complaints, DEQ sought mandatory injunctions requiring Duke Energy to assess and
abate what it alleged were threatened or claimed violations of North Carolina's
groundwater rules, found at Title 15A, Subchapter 2L of the North Carolina
Administrative Code (the "2L groundwater rules"), threatened or claimed violations of
North Carolina's water pollution laws set forth at N.C. Gen. Stat. § 143-215.1, and
threatened or claimed violations of National Pollutant Discharge Elimination System
("NPDES") permits at the above -referenced facilities ("Facilities") caused by the coal
combustion residuals ("CCR") surface impoundments, and to seek through mandatory
injunctive relief compliance with these laws, regulations, and rules.
8. In 2018 and 2019, DEQ issued NPDES permits (or, in the case of Marshall, a major
modification of an NPDES permit) for each of the Facilities except Roxboro. For
Roxboro, the NPDES permit is currently out for public comment. The NPDES permits
set effluent limits on the discharge of wastewater. Constructed seeps engineered
features on or within the dam structures (such as toe drains or filter blankets) to collect
seepage are incorporated as permitted outfalls in these NPDES permits with
monitoring and effluent limits.
149

9. In 2018, the Environmental Management Commission ("EMU) approved a Special
Order by Consent ("SOC") for each of the Facilities. The SOCs require accelerated
decanting —rem oval of free water from the surface of the CCR impoundments in a
manner that protects surface water quality. Decanting is expected to substantially
reduce or eliminate seepage flows of wastewater from CCR impoundments to non -
constructed or non -engineered seeps.
10. Subsequent to the filing of these actions, the General Assembly enacted Session Law
2014-122, which became effective on September 20, 2014. Part II of Session Law
2014-122 provided for the "Comprehensive Management of Coal Combustion
Residuals" and added new Part 2I to Article 9 of Chapter 130A of the North Carolina
General Statutes, which may be cited as the "Coal Ash Management Act of 2014"
("CAMA").
11. In July of 2016 CAMA was amended by House Bill 630, Session Law 2016-95.
Pursuant to this amendment, on November 13, 2018, after Duke Energy established
permanent water supplies to certain households and rectified deficiencies noted in dam
safety orders, DEQ classified the CCR impoundments at the above -referenced
Facilities as "low risk."
12. Pursuant to the provisions of CAMA and at the election of DEQ, low risk
impoundments may be closed by excavation, by capping in place largely in compliance
with the State rules for municipal solid waste landfills, or by closing in compliance
with the federal CCR Rule. N.C. Gen. Stat. § 130A-309.214(a)(3).

13. The CCR impoundments at each of the Facilities are as follows:
a. At Allen, there are two CCR impoundments, the Retired Ash Basin and the
Active Ash Basin. The Retired Ash Basin is approximately 123 acres and
contains approximately 6,100,000 tons of coal ash and the Active Ash Basin is
approximately 170 acres and contains approximately 10,480,000 tons of coal
ash.6 The Retired Ash Basin and the Active Ash Basin are CCR impoundments
as defined by CAMA, N.C. Gen. Stat. § 130A-309.201(6), and the Federal CCR
Rule 40 CFR Parts 257 and 261. For illustration purposes only, these CCR
impoundments are depicted on Exhibit A.
b. At Belews Creek, there is one CCR impoundment, the Ash Basin. The Ash
Basin is approximately 270 acres and contains approximately 11,970,000 tons
of coal ash. The Ash Basin is a CCR impoundment as defined by CAMA, N.C.
Gen. Stat. § 130A-309.201(6), and the Federal CCR Rule 40 CFR Parts 257 and
261. For illustration purposes only, this CCR impoundment is depicted on
Exhibit B.
c. At Buck, there are three CCR impoundments, Basin 1, Additional Primary
Pond/Basin ("Basin I"); Basin 2, Primary Pond/Basin ("Basin 2"); and Basin
3, Secondary Pond/Basin ("Basin 3"). There is also one ash stack. Basin 1 is
5 CCR impoundments are defined in CAMA, N.C. Gen. Stat. § 130A-309.201(6).
6 Note that the tonnage of coal ash includes only the coal ash contained within the CCR
impoundments and not coal ash in landfills or structural fills. Duke Energy Carolinas and Duke
Energy Progress, on the one hand, and DEQ and the Community Groups on the other, have a
dispute as to whether coal ash under a lawfully permitted landfill is regulated by CAMA. At Allen,
the Retired Ash Basin Landfill and subgrade is 25 acres and contains approximately 1,740,000
tons of coal ash. There are approximately 1,392,000 tons of coal ash beneath the Retired Ash
Basin Landfill, and approximately 991,000 tons of coal ash in the area designated as the "DORS"
area.
2

approximately 71 acres and contains 3,550,000 tons of coal ash. The ash stack
is adjacent to and partially above Basin 1, encompasses approximately 14 acres,
and contains approximately 263,000 tons of coal ash. Basins 2 and 3 are
separated by a divider dike built over ash, encompass approximately 57.5 acres
and 21.5 acres, respectively, and contain approximately 1,998,000 and 864,000
tons of coal ash, respectively. Basin 1 and the ash stack are contained within
one waste boundary, while Basin 2 and Basin 3 are contained in another waste
boundary. For illustration purposes only, these CCR impoundments are
depicted on Exhibit C.
d. At Cliffside/Rogers there are two CCR impoundments, the Unit 5 Inactive Ash
Basin and the Active Ash Basin. The Unit 5 Inactive Ash Basin is
approximately 46 acres and contains approximately 2,350,000 tons of coal ash
and the Active Ash Basin is approximately 86 acres and contains approximately
5,240,000 tons of coal ash. The Unit 5 Inactive Ash Basin and the Active Ash
Basin are CCR impoundments as defined by LAMA, N.C. Gen. Stat. § 130A-
309.201(6), and the Federal CCR Rule 40 CFR Parts 257 and 261. For
illustration purposes only, these CCR impoundments are depicted on Exhibit
lI
e. At Marshall, there is one CCR impoundment, the Ash Basin. The Ash Basin is
approximately 360 acres and contains approximately 17,650,000 tons of coal
ash.8 The Ash Basin is a CCR impoundment as defined by LAMA, N.C. Gen.
7 The Units 1-4 Ash Basin was fully excavated and closed in February 2018.

For illustration purposes only, this CCR impoundment is depicted on Exhibit
E.
f. At Mayo, there is one CCR impoundment, the Ash Basin. The Ash Basin is
approximately 153 acres and contains approximately 6,630,000 tons of coal
ash. The Ash Basin is a CCR impoundment as defined by CAMA, N.C. Gen.
Stat. § 130A-309.201(6), and the Federal CCR Rule 40 CFR Parts 257 and 261.
For illustration purposes only, this CCR impoundment is depicted on Exhibit
F.
g. At Roxboro, there are two CCR impoundments, the East Ash Basin and the
West Ash Basin. The West Ash Basin is approximately 225 acres and contains
approximately 12,970,000 tons of coal ash and the East Ash Basin is
approximately 71 acres and contains approximately 7,100,000 tons of coal ash.9
on the one hand, and DEQ and the Community Groups on the other, have a dispute as to whether
coal ash under a lawfully permitted landfill is regulated by CAMA. At Marshall, the Structural
Fill beneath solar panels contains approximately 6,490,000 tons of coal ash. The subgrade fill
beneath Industrial Landfill ("ILF") Cells 1 and 2 contains approximately 460,000 tons of coal ash.
The subgrade fill beneath ILF Cells 3 and 4, contains approximately 409,000 tons of coals ash.
The Old Ash Fill (1804 Phase I Landfill) contains approximately 626,000 tons of coal ash. The
Retired Landfill (1804 Phase II Landfill) contains approximately 4,870,000 tons of coal ash. The
ILF (Permit 18-12) contains approximately 2,050,000 tons of coal ash. The Marshall ILF
continues to receive production ash and these tonnages represent the approximate tonnages as of
December 31, 2019.
9 Note that the tonnage of coal ash includes only the coal ash contained within the CCR
impoundments and not coal ash in landfills or structural fills. Duke Energy Carolinas and Duke
Energy Progress on the one hand, and DEQ and the Community Groups on the other, have a
dispute as to whether coal ash under a lawfully permitted landfill is regulated by CAMA. For
Roxboro, the Roxboro Landfill contains approximately 6,818,000 tons of coal ash in one portion
of the landfill and an additional 7,635,000 tons of coal ash in a separate portion of that landfill.
The Roxboro Landfill continues to receive production ash and these tonnages represent the
approximate tonnages as of December 31, 2019.
8

The East Ash Basin and the West Ash Basin are CCR impoundments as defined
by CAMA, N.C. Gen. Stat. § 130A-309.201(6), and the Federal CCR Rule 40
CFR Parts 257 and 261. For illustration purposes only, these CCR
impoundments are depicted on Exhibit G.
14. On April 1, 2019, DEQ issued Coal Combustion Residuals Surface Impoundment
Closure Determinations ("Closure Determinations"), pursuant to its authority under
CAMA, electing and ordering excavation of the coal combustion residuals from the
CCR impoundments as the method of closure in compliance with CAMA at six of the
above -referenced Facilities: Allen, Belews Creek, Cliffside/Rogers, Marshall, Mayo
and Roxboro. DEQ's election of this method of closure was based upon its assessment
of the required statutory criteria as applied to these Facilities.
15. On April 26, 2019, Duke Energy filed six Petitions for Contested Case Hearing in the
North Carolina Office of Administrative Hearings ("OAH") challenging DEQ's
Closure Determination for each of these Facilities, and on May 24, 2019 Duke Energy
filed six Amended Petitions challenging subsequent DEQ actions related to the Closure
Determinations (the "OAH Proceedings"). Duke Energy has filed twelve petitions for
judicial review ("PJRs") appealing from two Orders issued in the OAH Proceedings.
16. Certain Plaintiff -Intervenors in these actions Appalachian Voices, MountainTrue,
Catawba Riverkeeper Foundation, Inc., Waterkeeper Alliance, Roanoke River Basin
Association, and The Sierra Club were allowed to intervene as Respondent -
Intervenors in the OAH Proceedings.
17. On December 31, 2019, the Parties, desiring to resolve and settle the OAH Proceedings
and related PJRs, and to ensure that the CCR impoundments are excavated on an
9

expedited basis and to remove any uncertainty associated with the litigation, entered
into a Settlement Agreement (the "Agreement"), obligating each of the parties to take
certain actions.
18. Pursuant to this Agreement, the Parties agreed to submit to the Court this Consent Order
incorporating the terms of the Agreement with the exception of certain provisions.
19. For impoundment sources of groundwater contamination at each Facility, the
obligations of Duke Energy Carolinas or Duke Energy Progress, as appropriate, are set
forth below, including the closure method to be employed for closing the CCR
impoundment(s) at each Facility, the requirements for remediating the alleged 2L
groundwater violations caused by the CCR impoundment(s) at each Facility, and the
requirements for addressing the alleged surface water violations at each Facility.
20. For any alleged 2L groundwater violations caused by sources other than CCR
impoundments at any Facility (e.g., on -site landfills, on -site structural fills, or coal piles
at certain Facilities), DEQ shall retain the authority to order appropriate corrective
action under its administration and implementation of the statutes, rules and regulations
under its purview. 10
21. The counter -obligations of DEQ and the Community Groups are also as set forth below.
to For clarity, the Parties understand the Complaints to address only groundwater contamination
caused by impoundment sources. Groundwater contamination, if any, caused by non -
impoundment sources is not resolved by this Consent Order and, as noted, will be separately
addressed through DEQ's administration of the statutes, rules and regulations that it implements.
By way of information, DEQ anticipates receiving Comprehensive Site Assessments for non -
impoundment sources of groundwater contamination that are not hydrologically connected to
impoundment sources on March 31, 2020 for Allen, Belews Creek, Cliffside/Rogers, Mayo and
Roxboro, and on July 1, 2021 for Buck.
f

INJUNCTIVE RELIEF
The Parties stipulate and agree that for the above -referenced Facilities, Duke Energy's
compliance with approved Groundwater Corrective Action Plans, NPDES permits, and SOCs,
along with the actions required by this Consent Order and through DEQ's administration of the
statutes, rules and regulations that it implements, have resolved or will resolve the remaining
alleged groundwater violations and surface water violations (i.e., those caused by impoundment
sources) set forth in the Complaints filed in these actions.'' Based upon the foregoing findings of
fact and conclusions of law as well as the stipulations of the Parties,12 IT IS THEREFORE
ORDERED, ADJUDGED, AND DECREED as follows:

of closure. DEQ will approve or disapprove a request for variance at the appropriate time.
15

Pine Hall Road Landfill, Duke Energy Carolinas shall conduct groundwater monitoring
(including the installation of new wells if reasonably necessary) and, upon re-formation
of surface water features that demonstrate DEQ-confirmed intermittent or perennial
flows (not merely precipitation), surface water sampling. Consistent with the
provisions of Paragraph 74, in this plan Duke Energy Carolinas shall propose (1)
additional groundwater remedial measures for any coal ash constituent if the data
indicate an increasing trend in groundwater concentrations in excess of the standards
set forth in i 5A NCAC 2L .0202 ("2L groundwater standards") for four (4) consecutive
semi-annual sampling events for that constituent, subject to the provisions of Paragraph
75, and (2) surface water treatment if the data shows impact from coal ash constituents

Order.
68. CCR Rule Deadlines. The Community Groups will not oppose Duke Energy
Carolinas's or Duke Energy Progress's efforts in court or in an administrative
proceeding to extend the deadlines imposed by the federal CCR rule to the extent that
such an extension is necessary to meet the obligations under this Consent Order. If
appropriate, the Community Groups will support such requests.
34

69. Deadlines for Coal Ash Recycling. The Community Groups will not oppose in court
or before an administrative body, extensions to the CAMA closure dates as may be
requested for the purposes of completing beneficiation at Buck, Cape Fear, and HF
Lee, through December 31, 2035. For purposes of this paragraph only, Cape Fear River
Watch, Inc., Waterkeeper Alliance, Sound Rivers, and Winyah Rivers Foundation
(together "additional community groups"), DEQ, and Duke Energy Progress consent
to amending the Order Granting Motion for Partial Summary Judgment entered on
April 4, 2016 and amended on June 9, 2017, with respect to Paragraph 19 (H.F. Lee)
and Paragraph 34 (Cape Fear). The signatures of these additional community groups
on this Consent Order shall apply only to the provisions of this paragraph. The Motion
seeking an amendment to the Order Granting Motion for Partial Summary Judgment
shall be filed separately from this Consent Order.
Further Obligations
70. Closure Method. The terms of this Consent Order satisfy the closure method
requirements of N.C. Gen. Stat. § 130A-309.214 for Duke Energy Carolinas and Duke
Energy Progress at the Facilities. In the event of inconsistency between this Consent
Order and the closure method ordered in DEQ's April 1 Closure Determinations, the
terms of this Consent Order shall control.26
71. Consent Order and Settlement Agreement. The Court takes judicial notice that the
Parties entered into a Settlement Agreement on December 31, 2019. Nothing in this
26 For clarity, this paragraph does not constitute approval of the closure plan. DEQ will approve
or disapprove the closure plan at the appropriate time.
35

Consent Decree is intended to alter, amend, or change any surviving obligations of the
Settlement Agreement. The Parties further agree that:
a. Except as set forth in Paragraph 72, below, the only State entity bound by this
Consent Order is DEQ.
b. Except as set forth in Paragraph 72, below, the resolution of cases or issues
pursuant to this Consent Order shall have no preclusive, res judicata, or collateral
estoppel effect against the State of North Carolina or any other State entity other
than DEQ.
c. Nothing in this Consent Order shall limit the arguments that may be made or
conclusions that may be drawn by other State entities in any matter or proceeding
concerning recovery through rates of costs incurred by Duke Energy.
72. Release of Claims. Notwithstanding any other provision of this Consent Order, for the
Facilities listed in Paragraphs 4 and 5, this Consent Order releases and resolves the civil
claims for injunctive relief set forth or which could have been set forth by Plaintiff
against Duke Energy Progress and Duke Energy Carolinas in the above -captioned
matters for past and continuing alleged violations of the water quality statutes and
regulations referenced in the Complaints based on information reasonably known to
DEQ at the time of filing of the Consent Order. For clarity, this release does not apply
to any alleged groundwater violations referenced in Paragraph 20.
73. No Limitation of Authority for Unknown or Future Endangerment. Plaintiff
retains all legal and equitable remedies to address any imminent and substantial
endangerment to the public health or welfare or the environment that is presently
unknown or which may arise in the future as a result of activities at the Facilities
36

whether related to the violations addressed in this Consent Order or otherwise. The
Parties reserve all legal and equitable remedies available to enforce the provisions of
this Consent Order, including requesting the Court to exercise its contempt powers.
74. Substantial Compliance. For any term of this Consent Order that requires compliance
with the 2L groundwater standards, neither Duke Energy Carolinas nor Duke Energy
Progress will be deemed to be in violation of any such term of this Consent Order and
shall not be subject to civil penalties or enforcement action by DEQ at a Facility
covered by this Consent Order so long as Duke Energy Carolinas or Duke Energy
Progress, as applicable, has used best efforts (as described in Paragraph 77) to
implement the Corrective Action Plan and post -closure monitoring and care plan unless
DEQ determines that there are multiple and material deviations from such standards at
or beyond the geographic limitation set forth in Paragraph 75.
75. Geographic Limitation. Active remediation will not be required in the area within 500
feet of the waste boundary of each CCR impoundment as shown on the most recent
NPDES permit for each of the Facilities (except that if a property boundary or body of
water is located closer than 500 feet to the waste boundary, that property boundary or
body of water shall define the geographic limits for active remediation) ("geographic
limitation"), provided that, subject to the provisions of Paragraph 74, coal ash
constituents outside the geographic limitation described in this paragraph do not
increase beyond the 2L groundwater standards post -closure. DEQ will not assess a
civil penalty or pursue an enforcement action for any exceedances of the 2L
groundwater standards within the geographical limitation so long as Duke Energy
Carolinas or Duke Energy Progress, as applicable, is making best efforts (as defined by
37

Paragraph 77). to implement the approved Corrective Action Plan and closure plan as
determined by DEQ. The Corrective Action Plans may be periodically updated as
required by DEQ if the groundwater cleanup fails to meet projected targets.
76. No Admission. No Party admits wrongdoing or liability related to matters covered in
this Consent Order.
77. Force Majeure. It will not be a violation of this Consent Order if performance of any
of the obligations contained in any paragraph is delayed by an extraordinary event that
is beyond the control of Duke Energy Carolinas or Duke Energy Progress, as
applicable, or any entity controlled by Duke Energy Carolinas or Duke Energy
Progress, as applicable, or their contractors, despite best efforts to fulfill the obligation.
Such causes are war, civil unrest, act of God, or act of a governmental or regulatory
body delaying performance or making performance impossible including any appeal or
decision remanding, overturning, modifying, or otherwise acting (or failing to act) on
a permit or similar permission or action that prevents or delays an action needed for the
performance of any of the work contemplated under this Consent Order such that it
prevents or substantially interferes with Duke Energy Carolinas's or Duke Energy
Progress's performance within the time frames specified herein. Duke Energy
Carolinas or Duke Energy Progress, as applicable, shall bear the burden of proving by
a preponderance of the evidence the existence of such circumstances. Such
circumstances do not include the financial inability to complete the work, increased
cost of performance, or changes in business or economic circumstances.
a. To qualify as a force majeure under this Consent Order, the failure of a permitting
authority to issue a necessary permit in a timely fashion which prevents Duke
38

Energy Carolinas or Duke Energy Progress from meeting the requirements in this
Consent Order must be beyond the control of Duke Energy Carolinas or Duke
Energy Progress, as applicable, and Duke Energy Carolinas or Duke Energy
Progress must have taken all steps available to obtain the necessary permit,
including but not limited to submitting a complete permit application, responding
to requests for additional information by the permitting authority in a timely
fashion, and accepting lawful permit terms and conditions after expeditiously
exhausting any legal rights to appeal those terms and conditions imposed by the
permitting authority.
b. The requirement that Duke Energy Carolinas and Duke Energy Progress use "best
efforts" in this Consent Order includes using commercially reasonable efforts to
anticipate any event that delays obligations and to address the event in a
commercially reasonable manner as it is occurring or following the event such that
delay is minimized to the greatest extent possible.
c. Duke Energy Carolinas or Duke Energy Progress, as applicable, shall notify the
Court, DEQ, and the Community Groups in writing within ten (10) days of
knowledge of the event which causes or may cause delay, describing in detail the
anticipated length of the delay, the precise cause or causes of the delay, the
measures taken and to be taken by Duke Energy Progress or Duke Energy Carolinas
to prevent or minimize the delay, and a timetable by which those measures will be
implemented. Failure to comply with the notice requirements constitutes a waiver
of any defense to a failure to comply with the terms and conditions of this Order.
39

The Parties may, in advance of the actual occurrence of an event causing delay,
move the Court for a determination as to whether the event will excuse the delay.
78. Obligations of the Defendants. Duke Energy Progress and Duke Energy Carolinas
shall be responsible for carrying out their respective obligations of the Consent Order
until relieved by the Court.
79. No Limitation on Administrative Process and Judgment. DEQ is a governmental
agency with statutory rights or obligations, and must abide by all applicable procedural
and substantive laws and regulations in the exercise of such authority during the
implementation of the provisions in this Consent Order. No provision in this Consent
Order shall diminish, modify, or otherwise affect the statutory or regulatory authority
of DEQ. For any provision in this Consent Order where DEQ makes a determination
on a matter, nothing in this Consent Order waives any rights of a Party under the North
Carolina Administrative Procedure Act (including the right to appeal, if any), nor does
a determination by DEQ on a matter prohibit a challenge to that determination under
the terms of this Consent Order, where appropriate. Nothing in this Consent Order
shall limit the opportunity for the Community Groups to participate in any
administrative process to the extent consistent with their commitments in this Consent
Order and as set forth in Paragraph 71.
80. Notice. Whenever notice is required to be given or a document is required to be sent
by one Party to another under the terms of this Consent Order, it shall be provided to
all Parties, directed to the individuals at the addresses specified below, unless those
individuals or their successors give notice of a change to the other Parties in writing.
Notice or submission by electronic mail is acceptable.

81. Effective Date. This Consent Order shall take effect immediately upon entry and shall
remain in effect until further order of this Court. The Parties shall comply with the
terms of this Consent Order.
82. Continuing Jurisdiction. The Court shall retain continuing jurisdiction to enforce the
terms and conditions of this Consent Order, to modify this Consent Order, and to
resolve disputes arising under this Consent Order. This Consent Order may be
41

modified, altered, or changed upon application to the Court by written consent of all
Parties. Absent consent of all Parties, a Party may seek modification or amendment of
this Consent Order only upon a showing of a substantial change of facts and
circumstances such that it would no longer be equitable to enforce the terms and
conditions of this Consent Order absent such modification or amendment. In the event
that any Party seeks such a modification or amendment without the consent of any other
Party, all Parties have the right to be heard by the Court. This Consent Order shall
remain in force and effect until all obligations and terms have been completed or
satisfied. Upon Duke Energy Carolinas and Duke Energy Progress demonstrating
completion of all obligations imposed by this Consent Order for each Facility to the
satisfaction of Plaintiff and Plaintiff -Intervenors, Plaintiff and Plaintiff -Intervenors
shall file appropriate notice and satisfaction documents with the Court.
83. Compliance. The parties agree that the actions required by this Consent Order
(including costs incurred) are for the purpose of complying with CAMA and coming
into compliance with applicable laws, rules, and regulations. For clarity, in ordering
methods of closure for the impoundments, DEQ did not seek to impose a fine or
penalty. This paragraph relates solely to issues arising under federal tax law.
84. Reporting. Duke Energy Carolinas and Duke Energy Progress shall submit annual
progress reports to DEQ detailing the work and activities undertaken and completed
pursuant to the requirements set forth in this Consent Order. The annual reports are
due no later than the thirtieth (30th) day of January for the duration of this Consent
Order.
42

85. Enforcement. The full power of the Court, including the contempt provisions of
Article 2, Chapter 5A of the North Carolina General Statutes, shall be available to
enforce this Consent Order. In no event shall any Party be entitled to monetary
damages for breach of this Consent Order. In addition, no action under this Consent
Order shall be brought or maintained until: (a) the non -breaching Party provides
written notice to the breaching Party which explains with particularity the nature of the
claimed breach, and (b) within thirty (30) days after receipt of said notice, the breaching
Party fails to cure the claimed breach or, in the case of a claimed breach which cannot
be reasonably remedied within a thirty (30) day period, the breaching Party fails to
commence to cure the claimed breach within such thirty (30) day period, and thereafter
diligently complete the activities reasonably necessary to remedy the claimed breach.
86. Signature. This Consent Order may be signed by the Court out -of -court, out -of -term,
and out -of -county, and by the Parties in counterparts.
