HELD BY )
DUKE ENERGY PROGRESS, LLC )
Pursuant to the provisions of North Carolina General Statutes (G.S.) 143-215.2,this Special
Order by Consent is entered into by Duke Energy Progress, LLC, hereinafter referred to as Duke
Energy, and the North Carolina Environmental Management Commission, an agency of the State
of North Carolina created by G.S. 143B-282, and hereinafter referred to as the Commission.
Duke Energy and the Commission are referred to hereafter collectively as the"Parties."
1. Stipulations: Duke Energy and the Commission hereby stipulate the following:
a. This Special Order by Consent("Special Order") addresses issues related to the
elimination of seeps (as defined in subparagraphs f and g below) from Duke
Energy's coal ash basins during the separate and independent process of basin
closure under the Coal Ash Management Act, G.S. 130A-309.200 through 130A-
309.231 ("CAMA") and the Federal Coal Combustion Residuals Rule,40 CFR
Parts 257 and 261. The Environmental Protection Agency first directed
permitting authorities to consider potential impacts on surface water of seeps from
earthen impoundments in 2010. At that time, Duke Energy began discussions
with the North Carolina Department of Environmental Quality("the
Department")regarding seeps at multiple Duke Energy facilities, including
identifying certain seeps in permit applications and providing data to the
Department regarding seeps. In 2014, Duke Energy provided a comprehensive
evaluation of all areas of wetness and formally applied for NPDES permit
coverage of all seeps. Since 2014, Duke Energy has performed periodic
inspections and promptly notified the Department of new seeps and sought
NPDES permit coverage where appropriate. On March 4, 2016, the Department
issued Notices of Violation ("NOVs")to Duke Energy related to seeps.

Both decanting and dewatering of the H. F. Lee Facility's coal ash basins will be
required before the ash basins can be closed. Decanting(i.e., removal of the free
water on the surface of the coal ash basin), has already been observed to affect
existing seeps at Duke Energy's H. F. Lee Facility. Removal of remaining coal
ash wastewater through continued decanting and dewatering(i.e. removal of
sufficient interstitial water) is expected to substantially reduce or eliminate the
seeps. In order to accomplish this goal of substantially reducing or eliminating
seeps,this Special Order affords certain relief to Duke Energy related to the non-
constructed seeps (as defined in subparagraph g below),while Duke Energy
completes activities associated with closure of the ash basins at the H. F. Lee
Facility. After completion of those activities, for any remaining seeps, Duke
Energy must take appropriate corrective action as specified more fully below.
b. Duke Energy has been issued a North Carolina NPDES permit for operation of an
existing wastewater treatment works at the following electric generation facility
(the "H. F. Lee Facility"):
Permit Issuance Receiving Water
Facility Number CountyDate for Primary
Outfall
H. F. Lee NC0003417 Wayne 07/23/2010 Neuse River
c. The H. F. Lee Facility listed above has ceased coal fired generation and now
consists of a 3 x 1 combined cycle unit capable of being fired on natural gas or
oil, and five simple cycle combustion turbines. The facility's coal ash basins still
exist, and are subject to the provisions of this Special Order.
d. The H. F. Lee Facility also has a permitted wastewater cooling pond that was used
during coal-fired operations, and continues to be used for the combined cycle
plant. Several areas of minor seep flow from the cooling pond to the Neuse River
have been observed. Chemical testing of the cooling pond seeps has revealed
some contain minor concentrations of coal combustion residuals (CCR). The
cooling pond seeps listed in Attachment A are also addressed by this Special
Order.
e. Wastewater treated at coal-fired electric stations includes water mixed with ash
produced through the combustion of coal for the steam generation process. Ash is
controlled and collected through the use of water, creating a slurry that is
conveyed to impoundments or basins with earthen dike walls. In the ash basin,
the solids separate from the liquid portion,with the resulting supernatant
discharged under the terms of the NPDES permit.
EMC SOC WQ S18-006
Duke Energy Progress,LLC
p. 3
f. The coal ash basins and the cooling pond at the H. F. Lee Facility are unlined,
having no impermeable barrier installed along their floors or sides. Earthen
basins and dike walls are prone to the movement of liquid through porous features
within those structures through a process known as seepage. The H. F. Lee
Facility exhibits locations adjacent to,but beyond the confines of, the coal ash
basins and the cooling pond where seepage of wastewater from those basins may
intermix with groundwater, reach the land surface (or"daylight"), and may flow
from that area. Once such seepage reaches the land surface, it is referred to as a
"seep." Each of the seeps identified at the H. F. Lee Facility and addressed in this
Special Order exhibit some indication of the presence of coal ash wastewater.
Both(a) confirmed seeps and(b) areas identified as potential seeps that were later
dispositioned, are identified in Attachment A.
g. Seeps that are not on or within the dam structure or that do not convey wastewater
via a pipe or constructed channel directly to a receiving stream are referred to as
"non-constructed seeps." Non-constructed seeps at the H. F. Lee Facility often
exhibit low flow volume and may be both transient and seasonal in nature, and
may, for example,manifest as an area of wetness that does not flow to surface
waters, a point of origin of a stream feature, or flow to an existing stream feature.
These circumstances of the non-constructed seeps make them difficult to discern,
characterize, quantify and/or monitor as discrete point source discharges. This
creates challenges in permit development and compliance monitoring because it is
difficult to accurately monitor for flow and discharge characterization. Non-
constructed seeps at the H. F. Lee Facility present significant challenges to their
inclusion in NPDES permits as point source discharges,but they do cause or
contribute to pollution of classified waters of the State. Therefore,these non-
constructed seeps are addressed in this Special Order rather than in an NPDES
permit.
h. Investigations and observations conducted by the Department and U. S. Army
Corps of Engineers staff have concluded that some seeps emanating from Duke
Energy's coal ash ponds create and/or flow into features delineated as classified
waters of the State or Waters of the United States.
Collectively,the volume of non-constructed seeps is generally low compared to
the volume of permitted wastewater discharges at the Duke Energy Facilities.
EMC SOC WQ S18-006
Duke Energy Progress,LLC
p. 4
j. In 2014, Duke Energy conducted a survey of each coal-fired electric generation
station to identify potential seeps from the coal ash surface impoundments. Duke
Energy included all areas of wetness identified around the impoundments as
seeps, and submitted applications to include those seeps in NPDES permits.
Beginning in 2015, Duke Energy has implemented semi-annual surveys to
identify new seeps in the vicinities of the coal ash basins. Additional seeps have
been observed and documented during these surveys and reported to the
Department pursuant to a Discharge Identification Plan mandated by CAMA.
Additional investigation has determined that not all of areas identified in 2014 are
seeps,but each Duke Energy facility does have multiple seeps.
k. The Department issued NOVs to Duke Energy on March 4, 2016 for the seeps
that emanate from the unlined coal ash surface impoundments at the Duke Energy
Facilities.
1. Non-constructed seeps create conditions such that certain surface water quality
standards may not consistently be met at all Duke Energy monitoring sites.
m. The presence of coal ash influenced water in the non-constructed seeps causes or
contributes to pollution of the waters of this State, and Duke Energy is within the
jurisdiction of the Commission as set forth in G.S. Chapter 143,Article 21.
n. A list of seeps identified in the vicinities of the coal ash surface impoundments at
the H. F. Lee Facility, as well as their locations, and the bodies of water those
seeps may flow into (if applicable), can be found in Attachment A to this Special
Order.
o. Duke Energy must close the coal ash surface impoundments at all North Carolina
coal-fired electric generating stations in accordance with applicable requirements
set out in CAMA and the Federal Coal Combustion Residuals Rule,requirements
of which are independent of the resolution of seeps addressed in this Special
Order.
p. Decanting of wastewater performed at Duke Energy's coal ash basins is expected
to eliminate or substantially reduce the seeps from the ash basins at the Duke
Energy Facilities.
q. Since this Special Order is by consent, the Parties acknowledge that review of the
same is not available to the Parties in the N.C. Office of Administrative Hearings.
Furthermore, neither party shall file a petition for judicial review concerning the
terms of this Special Order.

2. Duke Energy, desiring to resolve the matters causing or contributing to pollution of the
waters of the State described above, hereby agrees to do the following:
a. Penalties
1) Upfront Penalty. As settlement of all alleged violations due to seepage at
these Duke Energy Facilities,pay the Department,by check payable to the
North Carolina Department of Environmental Quality, a penalty in the
amount of$72,000, calculated based upon$6,000 each for twelve non-
constructed seeps identified prior to January 1, 2015.
A certified check in the amount of$72,000.00 must be made payable to
the Department of Environmental Quality and sent to the Director of the
Division of Water Resources(DWR) at 1617 Mail Service Center,
Raleigh,North Carolina 27699-1617 by no later than thirty(30)days
following the date on which this Special Order is approved and executed
by the Commission, and received by Duke Energy.
No penalty shall be assessed for seeps identified after December 31, 2014,
given Duke Energy's inclusion of seeps in permit applications and
compliance with the Discharge Identification Plan required under CAMA.
By entering into this Special Order, Duke Energy makes no admission of
liability,violation or wrongdoing. Except as otherwise provided herein,'
payment of the upfront penalty does not absolve Duke Energy of its
responsibility for the occurrence or impacts of any unauthorized
discharges in the area of the Duke Energy Facilities that may be
discovered in the future, nor does the payment preclude DWR from taking
enforcement action for additional violations of the State's environmental
laws.
I See especially paragraph 2(a)(2) excepting newly identified seeps from future penalties under
certain conditions.

Duke Energy is required to comply with the requirements of G.S. § 130A-
309.216. Duke Energy has announced plans to construct an ash beneficiation
plant at the H. F. Lee Facility capable of processing 300,000 tons of CCR material
per year.
1) The Coal Ash Management Act(G.S. § 130A-309.210)required the
cessation of CCR wastewater placement into the basins at the H. F. Lee
Facility by October 1, 2014. Duke Energy commenced decanting in April
2016. Decanting will be completed by March 31, 2019.
2) Dewatering will be required in order to excavate the ash for the purpose of
beneficiation. Duke Energy will begin the process of removal of
interstitial water from the H. F. Lee Facility no later than July 31, 2019
and will continue as needed to support the beneficiation plant described
above.
3) Once the dewatering process is initiated,within (30)days after the end of
each quarter, Duke Energy shall provide reports on the status of
dewatering work and other activities undertaken with respect to
excavation of each coal ash surface impoundment to DWR. The quarterly
reports are due by April 30, July 30, October 30, and January 30. The
reports are to be submitted as follows: one copy must be mailed to DWR's
Washington Regional Office Supervisor, 943 Washington Square Mall,
Washington,NC 27889, and one copy must be mailed to the Water
Quality Permitting Program, Division of Water Resources, 1617 Mail
Service Center, Raleigh NC 27699-1617. The quarterly reporting
requirement shall remain in force until completion of two years of
beneficiation operations.

4) Duke Energy shall conduct annual comprehensive surveys of areas down
gradient of the 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. 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.
5) No later than October 31, 2021 Duke Energy shall conduct a
comprehensive survey of areas down gradient of ash basins at the H. F.
Lee Facility, 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 this survey, including a section analyzing the
effect decanting of the basin(s)has had on seep flows, accompanied by
copies of the photographs noted above, shall be submitted to the Director
of DWR ("Final Seep Report"). This Final Seep Report must list any seep
that has been dispositioned(as described in subparagraph(4) above)
during decanting process, including an analysis of the manner of
disposition. The determination of whether a seep is dispositioned rests
with the Director of DWR. At, or at any time prior to, submission of the
Final Seep Report, Duke Energy shall seek formal certification from the
Director of DWR, certifying the disposition of any seep that Duke Energy
has characterized as dispositioned. Any seeps not certified as
dispositioned by the Director of DWR shall not be deemed as
dispositioned.
EMC SOC WQ S18-006
Duke Energy Progress,LLC
p. 9
6) If any seeps have not been certified by the Director of DWR as
dispositioned(as described in subparagraph 4) above),Duke Energy shall
conduct a characterization of those seeps.3 Duke Energy shall submit a
report on the findings of these characterizations ("Seep Characterization
Report")to the Director of DWR no later than December 31, 2021 (i.e.,
within 60 days of the submittal of the Final Seep Report). The Seep
Characterization Report must include all sampling data for each remaining
seep as well as Duke Energy's evaluation of the jurisdictional status of all
seeps at the H. F. Lee Facility. The determination regarding whether a
surface water feature is a classified water of the State rests with DWR.
7) Within 60 days of the submittal of the Seep Characterization Report,Duke
Energy shall submit a complete and adequate proposed amendment to the
groundwater Corrective Action Plan and/or Closure Plan as appropriate
for the Facility describing how any seeps identified in the Seep
Characterization Report will be managed in a manner that will be
sufficient to protect public health, safety, and welfare, the environment,
and natural resources. This proposed amendment will go to public
comment. Duke Energy shall submit documentation that the proposed
modification has been submitted to the appropriate division within the
Department that has authority for approving modification of the
groundwater Corrective Action Plan and/or Closure Plan. The content of,
and DEQ's review of, an amendment to a groundwater Corrective Action
Plan shall be consistent with Title 15A, Chapter 2L of the N.C.
Administrative Code (specifically including 2L.0106(h)-(o)). The
amendment to the Corrective Action Plan and/or Closure Plans shall be
implemented byDuke Energyin accordance with the deadlines contained
P
therein, as approved or conditioned by the Department. Failure by Duke
Energy to implement the amendment will be handled in the normal course
bythe Department in accordance with its enforcementprocedures (i.e.,
p
outside this Special Order). Notwithstanding the foregoing provisions of
this paragraph, any cooling pond seeps contained in the Seep
Characterization Report shall be addressed in a separate report(rather than
a proposed amendment to the groundwater Corrective Action Plan and/or
Closure Plan), specific to the matters of those seeps, and describe how
remaining cooling pond seeps will be managed in a manner that will be
sufficient to protect public health, safety, and welfare,the environment,
and natural resources. The report shall be submitted to DWR's Complex
3 If any seep is dispositioned between the time that the Final Seep Report is submitted and the
time the Seep Characterization Report is submitted, an analysis of the manner of disposition
must be included in the Seep Characterization Report, and Duke Energy must seek certification
of such a disposition from the Director of DWR. Only if such certification is received prior to
the due date of the proposed amendment described in paragraph 2(b)(7)may such a seep,
certified as dispositioned,be omitted from the proposed amendment.

• January 31, 2022; or
• 30 days following the approval of an amended groundwater
Corrective Action Plan and/or Closure Plan, as appropriate (if an
amendment is submitted in compliance with subparagraph 2(b)(7)
above).
c. Interim Action Levels.
I) Upon the complete execution of this Special Order, with regard to non-
constructed seeps, interim action levels for the receiving waters (which are
minor tributaries)are hereby established as noted in Attachment A. The
interim action levels are site-specific. Duke Energy shall monitor at
approved sampling sites to ensure interim action levels are met. Interim
action levels shall remain effective in the designated surface waters until
the applicable termination date in paragraph 2(b)(8) is reached.
2) Duke Energy shall perform monitoring of waters receiving flow from non-
constructed seeps in accordance with the schedules listed in Attachments
A and B, except as noted in paragraph 2(c)(3)below.
EMC SOC WQ S18-006
Duke Energy Progress,LLC
p. 11
3) If the monitoring of any classified water of the State receiving flow from
seeps regulated by this Special Order indicates exceedance of any interim
action level established by the Special Order, Duke Energy shall increase
monitoring at that location from quarterly to monthly until concentrations
of monitored characteristics return to those observed at the initiation of the
Special Order. If any interim action level established by the Special Order
is exceeded by more than 20% in a single sampling event, or exceeded for
two (2)consecutive monitoring events, in addition to paying the
associated stipulated penalty, Duke Energy shall conduct a re-assessment
of the contributing seep(s), including,but not limited to, evaluation of
proposed remedial actions for treatment and/or control of the seep such
that impacts to the receiving waters are quickly mitigated. A report
compiling the findings of the re-assessment, including proposed remedial
actions, shall be provided to the Director of DWR within 60 days of any
applicable exceedance. Following its review,DWR shall notify Duke
Energy of its concurrence or disapproval of Duke Energy's proposed
remedial actions.
4) Monitoring associated with seeps covered by this Special Order is exempt
from the electronic reporting requirements associated with NPDES
permits. Results of monitoring required exclusively per the terms of this
Special Order shall be reported to the Director of DWR in a
spreadsheet/worksheet format agreed to by Duke Energy and DWR.
Monitoring data shall be submitted to the Director of DWR in a digital
format no later than 30 days following the end of each calendar quarter for
as long as the Special Order is in effect. Monitoring data shall be sent to
the following email address: desocdata@ncdenr.gov. Data from those
sites with monitoring required exclusively per the terms of the Special
Order will be posted on DWR's website to provide the public with the
opportunity for viewing.
3. Duke Energy will continue to operate the H. F. Lee Facility's coal ash surface
impoundments in such a manner that their performance is optimized, and potential for
surface waters to be affected by seeps is minimized.
4. Duke Energy shall make available on its external website the NPDES permits,this
Special Order and all reports required under this Special Order for the H. F. Lee Facility
no later than thirty(30) days following their effective or submittal dates.

5. Duke Energy and the Commission agree that the stipulated penalties specified in
paragraph 2(a)(2) are not due if Duke Energy satisfies DWR that noncompliance was
caused solely by:
a. An act of God;
b. An act of war;
c. An intentional act or omission of a third party,but this defense shall not be
available if the act or omission is that of an employee or agent of Duke Energy or
if the act or omission occurs in connection with a contractual relationship with
Duke Energy;
d. An extraordinary event beyond the Duke Energy's control, specifically including
any court order staying the effectiveness of any necessary permit or approval.
Contractor delays or failure to obtain funding will not be considered as events
beyond Duke Energy's control; or
e. Any combination of the above causes.
6. Failure within thirty(30) days of receipt of written demand by DWR to pay the stipulated
penalties, or challenge them by a contested case petition pursuant to G.S. 150B-23,will
be grounds for a collection action,which the Attorney General is hereby authorized to
initiate. The only issue in such an action will be whether the thirty(30) days has elapsed.
7. Any non-constructed seeps causing or contributing to pollution of waters of the State
associated with the coal ash impoundments and the cooling pond at Duke Energy's H. F.
Lee Facility, and listed in Attachment A to this Special Order, are hereby deemed
covered by this Special Order. Any newly-identified non-constructed seeps discovered
while this Special Order is in effect, and timely reported to the Department per the terms
of CAMA and this Special Order, shall be deemed covered by the terms of the Special
Order, retroactive to the time of their discovery. Newly-identified non-constructed seeps
must be sampled for the presence of those characteristics listed in Attachment B to this
Order. Newly-identified non-constructed seeps found to be causing or contributing to
pollution of the waters of the State, with the effect of causing a violation of water quality
standards in surface waters not already referenced in the Special Order, may require
modification of the Special Order to address those circumstances.
8. Noncompliance with the terms of this Special Order is subject to enforcement action in
addition to the above stipulated penalties, including,but not limited to injunctive relief
pursuant to G.S. 143-215.6C or termination of this Special Order by the Director of DWR
upon ten (10) days' notice to Duke Energy. Noncompliance with the terms of this
Special Order will not be subject to civil penalties in addition to the above stipulated
penalties.
