< - concentration not detected at or above the adjusted reporting limit.
* - Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April, 1, 2013.
B2 - Target analyte was detected in blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
B3 - Target analyte was detected in Continuing Calibration Blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
D3 - Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
j - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
L3 - Analyte recovery in the laboratory control sample (LCS) exceeded quality control (QC) limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
M1 - Matrix spike recovery was high: the associated Laboratory Control Spike (LCS) was acceptable.
M2 - Matrix spike recovery was Low: the associated Laboratory Control Spike (LCS) was acceptable.
M4 - The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level. The associated Laboratory Control Spike recovery was acceptable.
M6 - Matrix spike and Matrix spike duplicate recovery not evaluated against control limits due to sample dilution.
N2 - The lab does not hold accreditation for this parameter.
P4 - Sample field preservation does not meet EPA or method recommendations for this analysis.
RI - Relative Percent Difference (RPD) value was outside control limits.
S - Associated calibration check did not meet specified criteria.

B2 - Target analyte was detected in blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
B3 - Target analyte was detected in Continuing Calibration Blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
D3 - Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
j - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
L3 - Analyte recovery in the laboratory control sample (LCS) exceeded quality control (QC) limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
M1 - Matrix spike recovery was high: the associated Laboratory Control Spike (LCS) was acceptable.
M2 - Matrix spike recovery was Low: the associated Laboratory Control Spike (LCS) was acceptable.
M4 - The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level. The associated Laboratory Control Spike recovery was acceptable.
M6 - Matrix spike and Matrix spike duplicate recovery not evaluated against control limits due to sample dilution.
N2 - The lab does not hold accreditation for this parameter.
P4 - Sample field preservation does not meet EPA or method recommendations for this analysis.
R1 - Relative Percent Difference (RPD) value was outside control limits.
S - Associated calibration check did not meet specified criteria.

< - concentration not detected at or above the adjusted reporting limit.
* - Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April, 1, 2013.
B2 - Target analyte was detected in blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
B3 - Target analyte was detected in Continuing Calibration Blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
D3 - Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
j - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
L3 - Analyte recovery in the laboratory control sample (LCS) exceeded quality control (QC) limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
M1 - Matrix spike recovery was high: the associated Laboratory Control Spike (LCS) was acceptable.
M2 - Matrix spike recovery was Low: the associated Laboratory Control Spike (LCS) was acceptable.
M4 - The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level. The associated Laboratory Control Spike recovery was acceptable.
M6 - Matrix spike and Matrix spike duplicate recovery not evaluated against control limits due to sample dilution.
N2 - The lab does not hold accreditation for this parameter.
P4 - Sample field preservation does not meet EPA or method recommendations for this analysis.

Deg C - Degrees Celsius mV - Millivolts S.U. - Standard Unit
DIS - Dissolved NA- Not analyzed Spec Cond - Specific Conductance
DO - Dissolved oxygen NE - Not established Temp - Temperature
Eh - Redox Potential NM - Not measured TOT- Total
mg - N/L - Milligrams nitrogen per liter NTU - Nephelometric turbidity unit ug/L - Micrograms per liter
mg/L - Milligrams per liter ORP - Oxidation -Reduction Potential umhos/cm - Micro mhos per centimeter
< - concentration not detected at or above the adjusted reporting limit.
* - Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April, 1, 2013.
B3 - Target analyte was detected in Continuing Calibration Blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
H1 - Analysis conducted outside the EPA method holding time.
M4 - The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level. The associated Laboratory Control Spike recovery was acceptable.

< - concentration not detected at or above the adjusted reporting limit.
* - Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April, 1, 2013.
B2 - Target analyte was detected in blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
B3 - Target analyte was detected in Continuing Calibration Blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
CH - The continuing calibration for this compound is outside of Pace Analytical acceptance limits. The results may be biased high.
D3 - Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
j - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
L3 - Analyte recovery in the laboratory control sample (LCS) exceeded quality control (QC) limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
M1 - Matrix spike recovery was high: the associated Laboratory Control Spike (LCS) was acceptable.
M2 - Matrix spike recovery was Low: the associated Laboratory Control Spike (LCS) was acceptable.
M4 - The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level. The associated Laboratory Control Spike recovery was acceptable.
N2 - The lab does not hold accreditation for this parameter.
P2 - Re -extraction or re -analysis could not be performed due to insufficient sample amount.
R1 - Relative Percent Difference (RPD) value was outside control limits.
S - Associated calibration check did not meet specified criteria.

0 - Bold highlighted concentration indicates exceedance of provisional background concentrations.
Deg C - Degrees Celsius Eh - Redox Potential NA - Not analyzed ORP - Oxidation -Reduction Potential Temp - Temperature umhos/cm - Micro mhos per centimeter
DIS - Dissolved mg - N/L - Milligrams nitrogen per liter NE - Not established pCi/L - picocuries per liter TOT- Total
DO - Dissolved oxygen mg/L - Milligrams per liter NM - Not measured S.U. - Standard Unit ug/L - Micrograms per liter
DUP - Duplicate mV - Millivolts NTU - Nephelometric turbidity unit Spec Cond - Specific Conductance ug/mL - micrograms per milliliter
< - concentration not detected at or above the adjusted reporting limit.
* - Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April, 1, 2013.
B2 - Target analyte was detected in blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
B3 - Target analyte was detected in Continuing Calibration Blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
CH - The continuing calibration for this compound is outside of Pace Analytical acceptance limits. The results may be biased high.
D3 - Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
j - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
L3 - Analyte recovery in the laboratory control sample (LCS) exceeded quality control (QC) limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
M1 - Matrix spike recovery was high: the associated Laboratory Control Spike (LCS) was acceptable.
M2 - Matrix spike recovery was Low: the associated Laboratory Control Spike (LCS) was acceptable.
M4 - The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level. The associated Laboratory Control Spike recovery was acceptable.
N2 - The lab does not hold accreditation for this parameter.
P2 - Re -extraction or re -analysis could not be performed due to insufficient sample amount.
R1 - Relative Percent Difference (RPD) value was outside control limits.
S - Associated calibration check did not meet specified criteria.

* - Interim Maximum Allowable Concentrations (IMACs) of the 15A NCAC 02L Standard, Appendix 1, April, 1, 2013.
B2 - Target analyte was detected in blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
B3 - Target analyte was detected in Continuing Calibration Blank(s) at a concentration greater than 1/2 the reporting limit but less than the reporting limit. Analyte concentration in sample is valid and may be used for compliance purposes.
CH - The continuing calibration for this compound is outside of Pace Analytical acceptance limits. The results may be biased high.
D3 - Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
j - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
L3 - Analyte recovery in the laboratory control sample (LCS) exceeded quality control (QC) limits. Analyte presence below reporting limits in associated samples. Results unaffected by high bias.
M1 - Matrix spike recovery was high: the associated Laboratory Control Spike (LCS) was acceptable.
M2 - Matrix spike recovery was Low: the associated Laboratory Control Spike (LCS) was acceptable.
M4 - The spike recovery value was unusable since the analyte concentration in the sample was disproportionate to the spike level. The associated Laboratory Control Spike recovery was acceptable.
N2 - The lab does not hold accreditation for this parameter.
P2 - Re -extraction or re -analysis could not be performed due to insufficient sample amount.
R1 - Relative Percent Difference (RPD) value was outside control limits.
S - Associated calibration check did not meet specified criteria.

Dear Mr. Sideris:
The .North Carolina Department of Environmental Quality's Division of Water Resources (DWR).
requests Duke Energy (Duke) provide data and conduct additional site assessment as needed to
characterize the distribution of coal ash residuals (CCR) at confirmed and potential coal ash
disposal areas at the James E. Rogers Energy Complex, Roxboro Steam Electric Plant, and the
W.H. Weatherspoon Plant. Descriptions and approximate locations of these areas are provided
below.
The additional assessments shall be included as part of the on-going Comprehensive Site
Assessments (CSAs) for each of the subject facilities. Please be advised that these areas are to be
included in an updated Groundwater Assessment Plan (GAP) that conforms with the North
Carolina Department of Environment and Natural Resources Notice of Regulatory Requirements
letter dated August 13, 2014 and Comprehensive Coal Ash Management Act (LAMA). Site
activities shall follow the requirements under 15A NCAC 02L .0106(g). An assessment of surface
water quality for those areas that have impounded or flowing water shall also be conducted.
Area(s) of Wetness (AOW) related to these disposal areas should be assessed pursuant to CAMA
§130A-309.212.

Additional Site Assessment Required
July 8, 2016
The results of the characterization conducted to date in addition to pertinent historical records and
detailed plans for additional site assessments must provide adequate detail to allow technical
review of the proposed actions shall be provided to the DWR..GAPs are due to the DWR Central
Office and the appropriate DWR Regional Office no later than August 19, 2016. Results of related
investigations may be submitted as a CSA Addendum Report at.a.later.date,
In addition to performing site assessment activities facility site maps :must be updated with.the
revised waste boundaries and proposed compliance boundaries, established according to 15A
NCAC 021 Section .0107. A letter requesting the approval of the new compliance boundaries
shall be submitted to the appropriate DWR Central Office later than August 19, 2016.
The following are background information and approximate locations of the identified areas at
each of the subject sites requiring additional assessment:
James E. Rogers Energy Complex
On November 16, 2015, Duke communicated orally to .DWR that a historical coal ash disposal
area located was identified just north of the Broad River and west of the switchyard at the James
E. Rogers Energy Complex. Duke staff estimated the area to be approximately 3 acres in size, but
stated that the full extent of the area is unknown. The approximate location of 'the area is shown
below encircled. This area was not addressed .in the Groundwater Assessment Plan (GAP),
Comprehensive Site Assessment (CSA) report, or Corrective Action Plans (CAPs) submitted to
DWR. Characterization of CCR within the footprint of this disposal area was confirmed by Duke;
however, no data related to this disposal area has been provided to DWR at this time.

Roxboro Steam Electric Plant
Area 1 - This area was discovered by Duke an& resented orally to DWR during a joint meeting ., .
on January 14, 2016. This area is located directly:east:of. the East Ash Basin and was subsequently .:
named by DWR the "Unnamed Eastern Extension Basin" for purposes of prioritization ranking- : =
according to the Coal Ash Management Act. This area shalLalso include the discharge canal that
runs north along the eastern side of the East Ash.Basin:: This area was not addressed in the GAP,,
CSA report, or CAPS submitted to DWR. The approximate location of the area is shown below
encircled.

Area 2 — This area is located directly south of the West Ash Basin and encompasses the three
"fingers" of the dammed watershed and the drainage canal that runs north along the west side of
the West Ash Basin. The drainage canal should be assessed for the presence of coal ash and surface
water standards. Based on site visits and information presented in the CSA and CAP reports, DWR
suspects that coal ash may be present in this area. This area was not addressed in the GAP, CSA
report, or CAPs submitted to DWR. The approximate location of the areas is shown below
encircled.

W. H. Weatherspoon Power Plant
Duke informed DWR orally at a joint meeting on October 21, 2015, that the cooling pond may
contain coal ash. Also, according to the CSA Report for the facility, the cooling pond is part of
the treatment process before the effluent is discharged through the NPDES outfall. This area was
not addressed in the GAP, CSA report, or CAN submitted to DWR; however, Duke has stated that
an investigation is currently underway. The approximate location of the area is shown below
encircled.

Dear Mr. Sideris:
On August 18, 2016, the North Carolina Department of Environmental Quality (DEQ) received
the proposed plans to conduct additional assessment activities for the subject facilities per our
request letter dated July 8, 2016. Based on a review of the plans and other information received
by DEQ Regional Office staff, conditional approval of the plans is granted. DEQ's approval is
contingent upon the following site specific conditions:
James E. Rogers Energy Complex
In the groundwater assessment report that will be provided following this investigation,
please include the AMSC Foster Wheeler ash sampling results (map and tabular data).
■ if monitoring well data indicate exceedances of the 15A NCAC 02L groundwater
standards, notify DEQ's Asheville Regional Office immediately so that deeper wells may
be located and installed expeditiously. The deeper well(s) would be needed to determine
the vertical extent of groundwater contamination_
■ DEQ concurs with the proposed boring/well locationsT of which six are,ash-related and one
is background.
State of North Carolina I Environmental Quality I Water Resources
1611 Mail service Center I Raleigh, North Carolina 27699-1611
919 707 9000

• DEQ concurs with the sample depth intervals for purposes of Unified Soil Classification
System descriptions.
+ Please revise the soil/ash sampling requirements as follows. For each of the six ash -related
boring locations, a lab analysis (constituents are listed in Table 2) should be conducted for -
all sampled depth intervals that contain visual evidence of ash. If 4 or more intervals
contain ash, conduct a lab analysis only on the shallowest ash -interval, the deepest ash
interval, and a composite ofthe remaining ash intervals, for a total of three ash lab analyses.
DEQ concurs with the 5 -foot minimum thickness criterion to determine when to analyze
variations in ash type (fly or bottom).
■ For soil sampling and lab analysis at each of the six ash -.related boring locations, DEQ
concurs with the two proposed sample intervals: 2 feet below the ash/soil interface and 8
to 10 feet below the ash/soil interface.
■ For SPLP analysis at each of the six ash -related boring locations, please conduct an analysis
on
o a) the sampled ash interval with the highest concentration of arsenic, selenium, and
strontium among all sampled ash intervals at that location, and
o b) a sample composited from the two sampled soil intervals at that location.
For soil sampling and analysis at the background boring location, please collect:
o a) one shallow soil sample at a depth that approximates the general depth of most
of the shallow soil samples from the other six borings,
o b) one deeper soil sample at a depth that approximates the general depth of most of
the deeper soil samples from the other six borings, and
o c) one SPLP sample that is a composite of the shallow and deeper intervals in a)
and b) above.
■ Please revise Section 2.2.3 to read that if inaccessible from the bank, a boat should be used
to collect three surface water samples upstream, adjacent to, and downstream of the AO.ls.
These samples should be collected immediately adjacent to the bank during conditions that
approximate low or baseflow to the maximum extent possible and at least 5 days after a
previous rain event of any magnitude. Contact DEQ's Asheville Regional Office if this
request becomes difficult to meet based on weather conditions. Antecedent rainfall (prior
5 days and prior 48 hours) should be provided, along with its measurement location, as a
footnote in surface water results table.
Roxboro Steam Electric Plant
• In the groundwater assessment report that will be provided following this investigation,
please identify on a map all private supply well's within a :'% mile radius of an assumed
compliance boundary around the study area, monitor- yell locations, any areas of wetness,
and surface water features.
• DEQ recommends additional monitoring we11s-�.td- be. installed in each water=bearing
hydrostratigraphic unit at a nested well location'south.:east o:f existing well MW-12BR. '

• DEQ recommends relocating any proposed sampling point locations where insufficient
sediment recovery is an issue.
W. H. Weathers oon Power Plant
• In the groundwater assessment report that will bei provided following, this investigation,
please identify on a map all private supply wells -within a'/2 mile radius ofan assumed
compliance boundary around the study area, monitor well locations,._any areas of wetness,
and surface water features.
DEQ recommends moving the proposed sample location JC -1 to the drainage feature
before it enters the creek (coordinates N 34.5902, W 78.9660)
In response to your "Proposed Waste and Compliance Boundaries" letter dated August 19, 2016, DEQ
cannot approve the proposed revised compliance boundary locations for the subject facilities at this time.
DEQ will provide correspondence and direction regarding this issue in the near future.
Submit the findings of the site assessments for each subject facility as a groundwater site
assessment report. The respective site assessment reports shall include figures, tables, cross-
sections, and maps in a manner that provides an interpretation of site conditions. In each report,
include a map that shows all private supply wells, monitoring well locations, any areas of wetness,
and surface water features within a'/2 mile radius of a previously established compliance boundary
around the study area. Reports submitted in a data summary format will not be approved as an
acceptable documentation of findings. Submit site assessment reports for each facility by March
31, 2017.
Please begin implementing these plans immediately to include the conditional .items listed. For general
questions, contact Steve Lanter at (91.9) 807-6444. For more specific questions, please contact our

Dear Sir or Madam:
The subject erosion and sedimentation control plan was approved by default. The Sedimentation Pollution
Control Act (hereinafter "Act") states that this plan must be filed a minimum of 30 days (15 days for
revised plans) prior to the activity and the approving authority must approve or disapprove the submitted
plan within 30 days (15 days for revised plans) of receipt of G.S. 113A-54.1. The Act further states that if
the approving authority fails to approve or disapprove the submitted plan within the 30 -day (15 days for
revised plans) period, the plan will be deemed approved. The enclosed Certificate of Approval must be
posted at the job site. This plan approval shall expire three (3) years following the date of approval, if no
land -disturbing activity has been undertaken, as is required by Title 15A NCAC 4B .0129.
Title 15A NCAC 4B .0118(a) requires that a copy of the approved erosion control plan be on file at the
job site. Also, this letter gives the notice required by G.S. 113A -61.1(a) of our right of periodic
inspection to insure compliance with the approved plan.
North Carolina's Sedimentation Pollution Control Act is performance -oriented, requiring protection of
existing natural resources and adjoining properties. ifJollowing the commencement of this project, the

erosion and sedimentation control plan is inadequate to meet the requirements of the Sedimentation
Pollution Control Act of 1973 (North Carolina General Statute 113A-51 through 66), this office may
require revisions to the plan and implementation of the revisions to insure compliance with the Act.
The developer is responsible for obtaining any and all permits and approvals necessary for the development of
this project prior to the commencement of this land disturbing activity. This could include agencies such as the
DEMLR stormwater regulations, their enforcement requirements within Section 401 of the Clean Water Act, the
Environmental Protection Agency and/or the U.S. Army Corps of Engineers' jurisdiction of Section 404 of the
Clean Water Act, the Division of Solid Waste Management's landfill regulations, local County or Municipalities'
ordinances, or others that may be required. This approval cannot supersede any other permit or approval;
however, in the case of a Cease and Desist Order from the Corps of Engineers, that Order would only apply to
wetland areas. All upland areas would still have to be in compliance with the N.C. Sedimentation Pollution
Control Act.
If any area on site falls within the jurisdiction of Section 401 or 404 of the Clean Water Act, the developer is
responsible for compliance with the requirements of the Division of Water Resources, the Corps of Engineers and
the Environmental Protection Agency (EPA) respectively. Any erosion control measures that fall within
jurisdictional wetland areas must be approved by the aforementioned agencies prior to installation. DEMLR must
be notified of a relocation of the measures in question to the transition point between the wetlands and the uplands
to assure that the migration of sediment will not occur. If that relocation presents a problem or contradicts any
requirements of either DWR, the Corps, or the EPA, it is the responsibility of the developer to inform the
DEMLR regional office so that an adequate contingency plan can be made to assure sufficient erosion control
remains on site. Failure to do so will be considered a violation of this approval.
Please be aware that your project will be covered by the enclosed NPDES General Stormwater Permit
NCGO10000 (Construction Activities). You should first become familiar with all of the requirements for
compliance with the enclosed general permit.
You are requested to file an amended Financial Responsibility/Ownership Form, if there is any change in
the information provided to our office at the time of the initial plan submittal. In addition, it would be
helpful if you notify this office of the proposed starting date for this project. Please notify us if you plan
to have a preconstruction conference.

Dear Mr. Zimmerman:
On August 18, 2016, Duke Energy (Duke) submitted Work Plans for additional assessment
activities at the James E. Rogers Energy Complex (Rogers), Roxboro Steam Electric Plant
(Roxboro), and W.H. Weatherspoon (Weatherspoon) Power Plant. On November 23, (revised
December 2, 2016) Duke received North Carolina Division of Environmental Quality Division of
Water Resources (DWR) approval to the Additional Site Assessment Approvals for these three
facilities noting a reporting due date of March 31, 2017.
On November 30, 2016 in a meeting with DWR Regional office personnel, Duke made DWR
aware that permitting and constructability of monitoring wells would likely extend the schedules
for assessment beyond the March 31, 2017 date specified in the November 23 letter.
With this letter, Duke requests a 60 -day extension for the Additional Site Assessment Plans at
Roxboro and Weatherspoon, and an extension until after ash removal is complete at Rogers.
The extension request for these sites is outlined in more detail below:
James E. Rogers Energy Complex
• The area requested for additional assessment at Rogers is an ash area across the
Broad River near the Unit 5 switchyard. This area has tentatively been scheduled to
begin excavation in the second quarter of 2017 pending receipt of necessary permits.
Wells installed in the area of excavation would need to be abandoned prior to beginning
excavation resulting in reinstallation of most of the wells. Duke requests that installation
of the additional site assessment wells be postponed until completion of ash removal
from the area across the Broad River. Duke intends to propose an alternate schedule
once there is more c)arily on the completion dale of ash removal, Preliminary
discussions have occurred with Asheville Regional Office ori this topic:

Mr. S. Jay Zimmerman, Director
January 27, 2017

Roxboro Steam Electric Plant
■ Work Plan Schedule
Section 8.0 Proposed Schedule of the work plan noted that field work would
begin approximately 45 days following final NCDEQ approval with the CSA
Report submitted 60 days after receipt and validation of analytical data. The
proposed schedule accounted for permitting and assessment of data obtained
during the site assessment. The schedule submitted in the Work Plan was
aggressive with any alterations leading to the potential submittal of an incomplete
report.
• Additional monitoring well location
The Correction to the Additional Site Assessment Approvals requested one
additional monitoring well cluster at a location southeast of MW-12BR. Duke
noted that the requested location was likely an error with the actual location
southwest of MW-12BR. Clarification for well cluster location was directed to
NCDEQ on November 27, 2016. Confirmation of final cluster location was
received from NCDEQ on December 1, 2016.
• Permit Requirement
The area of disturbance for the 7 well cluster locations is greater than 1 acre and
therefore requires an Erosion and Sediment Control (E&SC) Permit from NCDEQ
Division of Land Quality. The initial E&SC permit application was submitted on
November 30, 2016 with a revision for the additional well cluster submitted on
December 6, 2016. Clearing and creation of roadways/pads cannot begin until
the E&SC permit is received.
■ Feasibility of compressed schedule
Installation of access roads/pads and utility clearance will begin upon receipt of
E&SC permit. However, the work is weather -dependent with driller mobilization
not anticipated until approximately two weeks after start of work with clearing and
road/pad installation continuing as well installation begins.
o Well installation and development - approximately 2 to 3 weeks
o Collection of groundwater and other media samples - approximately 1
week
o Analytical analysis - approximately 3 to 4 weeks
o Data validation of analytical results - approximately 1 week
o Report development and review - approximately 4 weeks

The installation of six wells on the cooling pond dam required Dam Safety work
plan approval by the NC Division of Energy, Mineral, and Land Resources.
Approval was received on January 12, 2017. Aligning drilling resources could
not begin until this approval was received.
Feasibility of Compressed Schedule
The following estimated durations beginning on the receipt date of the Dam
Safety approval will move completion beyond the March 31, 2017 report date
specified in the "Correction to the Additional Site Assessment Approvals" letter:
o Well installation and development - approximately 2 to 3 weeks
o Collection of groundwater and other media samples - approximately 1

The facility operates five internal outfalls and two outfalls to Hyco Reservoir. Duke requested
the addition of two new outfalls on the permit; one to reflect the future treatment system for the
low volume wastes as the ash basin will be closed and one for seeps and stormwater.
Description of existing outfalls:
• Outfall 003 - Heated Discharge Canal to Hyco Reservoir. The discharge canal combines
all internal outfalls (002, 005, 008, 009, 010) before discharging to Hyco Reservoir. In
addition, once -through cooling water from condensers for units 1,2, and 3, once -through
cooling water from heat exchangers, seepage from ash pond, and stormwater runoff
from plant drainage areas are discharged to the discharge canal.
Outfall 006 - Coal Pile Runoff discharges directly to Hyco Reservoir. Coal pile runoff
wastewaters include runoff from the coal pile, limestone pile and gypsum pile, truck
wheel wash area and coal handling areas. Treatment is accomplished by neutralization,
sedimentation and equalization.
Internal Outfall 002 - Ash Pond discharging to the discharge canal. The ash pond
receives wastewater from the following source:
• Bottom ash transport waters
• Silo wash water
• Ash landfill leachate and runoff (this landfill receives CCR from Mayo and
Roxboro plants)
• Dry -ash handling system wash water
• Blowdown from Unit 4 cooling tower
• Coal mill rejects and pyrites
• Sewage treatment plant effluent
• Low volume waste consisting of boiler blowdown, equipment maintenance
cleaning wastewaters, RO reject wastewater and floor drains. Low volume
wastes are treated by neutralization.
• Emergency overflow from FGD system blowdown.
The ash pond uses precipitation, adsorption, and settling for treatment, which has been
determined by NC to be BAT for this facility.
• Internal Outfall 005 - Cooling tower blowdown from Unit 4.
• Internal Outfall 008 - Treated domestic wastewater. The treatment system consists of a
screen, communitor, surge tank, aeration tank, clarifier, chlorine contact chamber and
sludge holding tank. A new package plant will be installed to replace the existing plant.
• Internal Outfall 009 - Chemical metal cleaning waste. Wastewaters from cleaning of the
boilers is generated every five to eight years. Every three to five years wastewaters are
generated from cleaning the heat exchangers. The wastewaters generated can be treated
by evaporation or by neutralization and precipitation.
• Internal Outfall 010 - Flue Gas Desulfurization (FGD) treatment system discharging to
the discharge canal. The scrubber system removes SOx by mixing flue gas with a

NPDES No. NC00003425
limestone slurry. The blowdown from the scrubber is discharged to a gypsum settling
pond system then to a bioreactor which utilizes microorganisms to reduce soluble
contaminants to insoluble forms (under anaerobic conditions) that then precipitate from
solution. Wastewater is discharged to the ash pond effluent channel. An emergency
overflow from the FGD system blowdown discharges to the ash pond.
Proposed Outfalls:
Outfall 001 (Seeps) - The facility identified 16 unpermitted seeps. Seven seeps are
engineered drains from the ash basin flowing to the discharge canal. Four non -
engineered seeps also flow to the discharge canal. Four seeps from the ash landfill and
one from the gypsum pile flow to the intake canal through a common outfall. This
outfall was previously designated as outfall 001 in the permit and will be reinstated to
monitor the seeps.
Internal Outfall 012 - Low volume waste and other wastewaters. Duke will build a new
dual basin treatment system to treat wastewaters than now go to the ash basin.
CWA 316 (b)
The permittee shall comply with the Cooling Water Intake Structure Rule per 40 CFR 125.95.
The Division approved the facility request for an alternative schedule in accordance with 40
CFR 125.95(a)(2). The permittee shall submit all the materials required by the Rule with the next
renewal application.
Temperature Mixing Zone - Outfall 003
The facility is located in the Lower Piedmont area of the state, the applicable state water quality
temperature standard is 32°C (89.6'F). The authorized temperature mixing zone for outfall 003
includes the North Hyco Arm downstream of NC Hwy 57, the main body of Hyco Reservoir
downstream of the confluence of the Cobbs Creek Arm and the North Hyco Arm and the entire
afterbay lake. USGS data at the afterbay monitoring station (USGS Station 02077303) was
reviewed for the period of January 2011 to April 2016. Data shows that the temperature water
quality standard was not exceeded for this period. Maximum temperature recorded was 30.5°C.
Instream Monitoring
The permit requires monitoring of Hyco Reservoir in accordance to the Biological Monitoring
Program as approved by the Division. Based on the Division's review of the reports the fish
community is comparable to other piedmont reservoirs and no problems were noted.

Internal Outfall 002 - Dewatering
To meet the requirements of the Coal Ash Management Act of 2014, the facility needs to
dewater two ash ponds by removing the interstitial water and excavate the ash to deposit it in
landfills. The facility's highest discharge rate from the dewatering process will be 1 MGD. The
facility submitted data for the standing surface water in the ash ponds, interstitial water in the
ash, and interstitial ash water that was treated by filters of various sizes. The following
pollutants were detected at concentrations higher than the water quality standards: selenium,
arsenic and molybdenum. A new effluent and monitoring sheet is included in the permit for the
ash pond dewatering phase. As this is an internal outfall the water quality standards are not
applied. Monitoring will be required for selenium, arsenic, molybdenum, antimony and copper.
Ash Pond Dams:
Seepage through earthen dams is common and is an expected consequence of impounding
water with an earthen embankment. Even the tightest, best -compacted clays cannot prevent
some water from seeping through them. Seepage is not necessarily an indication that a dam has
structural problems, but should be kept in check through various engineering controls and

regularly monitored for changes in quantity or quality which, over time, may result in dam
failure.

Reasonable Potential Analysis Outfall 003:
The Division conducted EPA -recommended analyses to determine the reasonable potential for
toxicants to be discharged at levels exceeding water quality standards/ EPA criteria by this
facility from outfall 003. For the purposes of the RPA, the background concentrations for all
parameters were assumed to be below detection level. The RPA uses 95% probability level and
95% confidence basis in accordance with the EPA Guidance entitled "Technical Support
Document for Water Quality -based Toxics Control." With the approval of the Triennial Review
(2007-2014) of the NC Water Quality Standards by the Environmental Management
Commission (EMC) in 2014 and US -EPA (with some exceptions) on April 6, 2016, the NPDES
Permitting Unit is required to implement the new dissolved metal standards in all permits
public noticed after April 6, 2016. The RPA included evaluation of dissolved metals' standards,
utilizing measured hardness value of 100 mg/L CaCO3 for hardness -dependent metals.
A reasonable potential analysis was conducted for arsenic, copper, nickel, selenium, strontium,
thallium, chlorides and zinc. Arsenic data used for the RPA was collected between 2011 and
2016. Data for the remaining parameters was from a special study for the period of March 2010
to August 2011. Based on this analysis, the following permitting actions are proposed for this
permit:
• Monitoring Only. The following parameters will receive a monitor -only requirement
since they did not demonstrate reasonable potential to exceed applicable water quality
standards/ criteria, but the maximum predicted concentration was >50% of the
allowable concentration: Arsenic, selenium, chloride and thallium.
• No Limit or Monitoring: The following parameters will not receive a limit or monitoring,
since they did not demonstrate reasonable potential to exceed applicable water quality

NPDES PERMIT FACT SHEET

NPDES No. NC00003425
standards/ criteria and the maximum predicted concentration was <50% of the
allowable concentration: copper, nickel, strontium, and zinc.
Mercury Evaluation Outfall 003:
A mercury evaluation was conducted in accordance with the permitting guidance developed
for the implementation of the statewide Mercury TMDL to determine the need for a limit and
Mercury Minimization Plan (MMP). Monitoring for mercury is not required for outfall 003 but
mercury data was collected during a special study during the period of March 2010 to August
2011. The water quality based effluent limitation (WQBEL) for mercury is 12 ng/1. The
technology based effluent limit (TBEL) is 47 ng/1. None of the annual averages exceeds the
WQBEL or TBEL, no limit is required. See the attached mercury evaluation spreadsheet.
