Person County Government Building at 304 South Morgan St in Roxboro. The purpose of
this public meeting is to discuss the Coal Combustion Residual Impoundment Risk
Classifications at Duke's Mayo and Roxboro Steam Electric Plants in Person Co.
Good evening. My name is Elizabeth Werner. I have been appointed by the North
Carolina Department of Environmental Quality to preside at this public meeting. I am a
permitting hydrogeologist with the N.C. Division of Waste Management in Raleigh.
I am joined tonight by other staff from the N.C. Department of Environmental Quality.
They are:
• Jason Watkins, field operations branch head in the Division of Waste
Management
• Jamie Kritzer, public information officer
• Ed Mussler, permitting branch supervisor in the N.C. Division of Waste
Management
• Shannon Aufman, permitting environmental engineer in the Division of Waste
Management
• Larry Frost, permitting engineer with the Division of Waste Management
• Shawn McKee, environmental senior specialist with Division of Waste
Management
• Jessica Montie, compliance officer with the Division of Waste Management
I'd also like to recognize any staff with the N.C. Department of Health and Human
Services in attendance tonight.
I appreciate everyone's attendance and would like to take this time to recognize any
public officials in attendance tonight.
(Staff from the registration table will provide a list if any elected officials sign in.)

Now I would like to invite any additional elected officials to stand and introduce
themselves.
This meeting is being held under the authority of North Carolina General Statutes
Chapter 130A-309.200 and 130A-309.213, which requires the department to develop
proposed classifications for all coal combustion residuals surface impoundments,
including active and retired sites, for the purpose of closure and remediation. Within 30
days of the receipt of all public comments, the department must finalize its
recommendations for classifications for coal combustion residuals impoundments at
Duke Energy facilities statewide.
As meeting officer, it is my responsibility to listen to your comments and assist in the
preparation of a report, which summarizes the information presented tonight and
provides recommendations on the classification of coal combustion residuals
impoundments at the Mayo and Roxboro Steam Electric Plants. To aid the department
in preparing the report, audio of tonight's meeting is being recorded. In addition, I ask
that you provide me with a written copy of your comments if possible. Comments
should be relevant to the issue of coal combustion residuals impoundment risk
classifications for the Mayo and Roxboro Steam Electric Plants in order to be considered
in the final recommendation.
At this time, I will provide an overview of how the meeting will be conducted:
1. Staff will give a presentation which summarizes the draft risk classifications for the
Mayo and Roxboro Steam Electric Plants. Following the staff presentation, I will hear
all oral comments relevant to the issue of coal combustion residuals impoundment
risk classifications for the Mayo and Roxboro Steam Electric Plants.
2. 1 will call on speakers in the order they signed up to speak.
3. Each speaker will be limited to minutes.
(Adjust the time limit as needed if a very large crowd attends.)
4. There will be no cross-examination of speakers or division staff.
5. All public comments will be directed to me as the meeting officer.
6. 1 ask that everyone respect the right of others to speak without interruption.

At this time, I will give a brief summary of the risk classifications for the Mayo and
Roxboro Steam Electric Plants.
(Presentation)
Now, we will hear from audience members who wish to speak in the order that they
registered. Please limit comments to minutes so that everyone who wishes to
speak has an opportunity to do so.
As you may be aware, recently state health officials have amended some of the usage
recommendations regarding well water. This recent decision does not have an impact
on the Coal Combustion Residual Impoundment Risk Classifications process.
The department may only consider technical and scientific information related to the
risk classification of the Mayo and Roxboro Steam Electric Plants when making
recommendations for the final classification. Other issues concerning this facility or the
issue of coal combustion residuals as a whole are beyond the scope of this public
meeting.
When your name is called, please come to the podium, state your name and indicate
any group you may be representing or affiliated with. To ensure that we hear from all
who wish to speak, there will be a minute time limit for providing comments. Staff
will keep track of the time and raise a sign to indicate when you have 1 minute
remaining and when you have 30 seconds remaining to finish your comments. Please
keep your comments concise and limit them to the issue of coal combustion residuals
impoundment risk classifications for the Mayo and Roxboro Steam Electric Plants. I
appreciate your cooperation in complying with these requests.
(Call out names.)
That concludes tonight's line-up of speakers. We have use of this meeting room for a set
time period, so department staff will not be available for questions or comments after

the meeting. However, comments may be submitted through April 18 by sending an
email to: [e-mail] and [e-mail].
I would like to thank you all for attending tonight's meeting. Your input is greatly
appreciated.
After careful study of all comments received and the requirements of state laws and
administrative rules, the department will make a recommendation based on this
meeting on the coal combustion residual impoundment risk classifications for the Mayo
and Roxboro Steam Electric Plants.
This meeting is adjourned.

COAL COMB USTION RESID UAL IMPO UNDMENT
RISK CLASSIFICATIONS
Background:
• Under the historic Coal Ash Management Act (CAMA) of 2014, all coal ash
impoundments in North Carolina are required to be closed.
• The deadlines for closure depend on the classification of each
impoundment as low, intermediate, or high.
• CAMA required the Department of Environmental Quality (DEQ) to make
available to the public a summary of the initial draft proposed
classifications in December 2015, and a full report in January 2016.
• These draft proposed classifications are based on the information
available to the department as of December 2015 and are posted on the
departments website, local library, and health department.
Department of Environmental Quality

COAL COMB USTION RESID UAL IMPO UNDMENT
RISK CLASSIFICATIONS
After the release of the summary of the initial draft proposed classifications,
CAMA requires the following process:
• DEQ must make available a written declaration that is a detailed report
explaining the technical and scientific background data and analyses
behind the draft proposed classifications.
• Publish a summary of the detailed report in the local newspapers.
• Make the report available to the local health director and accessible at the
local library.
• A public meeting in each county with a coal ash facility.
• Consider all public comments and develop final proposed classifications.

COAL COMB USTION RESID UAL IMPO UNDMENT
RISK CLASSIFICATIONS
Four of Duke's 14 facilities are designated as high -risk by the coal ash law.
Under CAMA, the department is required to consider the following factors,
at a minimum, in proposing classifications for the remaining 10 facilities:
1. Any hazards to public health, safety, or welfare.
2. Structural condition and hazard potential.
3. Consideration of surface
4. Consideration of groundwater.
5. The location and nature of all receptors.
6. All factors influencing the movement of contaminants.
7. Consideration of coal combustion residuals in the impoundment.
8. Position in 100-year flood plain
9. Any other factor the department deems relevant to the establishment of risk.

COAL COMB USTION RESID UAL IMPO UNDMENT
RISK CLASSIFICATIONS
The department incorporated all of the preceding criteria into three primary
categories that were used to evaluate each impoundment:
• Structural Integrity
• Impact to Surface Water
• Impact to Groundwater
The draft classification process was iterative and occurred over a series of
months. Recommendations regarding the impoundments were amended
and updated as additional scientific and technical information was received,
reviewed and verified.

ROXBORO STEAM ELECTRIC PLANT RISK
CLASSIFICATION
Overall Risk Classification
DEQ has proposed the risk classification for the East Ash Pond as Low -to -
Intermediate.
Groundwater Key Factor: Based on the information received to date, there
appears to be no downgradient receptors located 1,500 feet downgradient
of the impoundment compliance boundary. The following data gaps related
to groundwater uncertainty include:
• Additional areas adjacent to the current impoundment may contain CCR and
would therefore require additional assessment
• Incomplete capture zone modeling
• Incomplete geochemical modeling
• Incomplete background concentration determination
(Data gaps are currently being addressed by Duke Energy and their findings
will be presented to the DEQ in supplemental reports.)
Department of Environmental Quality

ROXBORO STEAM ELECTRIC PLANT RISK
CLASSIFICATION
DEQ has proposed the risk classification for the Unnamed Eastern
Extension Impoundment as Intermediate.
• This impoundment was just recently identified by Duke Energy and assessment
is currently underway
• The location of the impoundment is in close proximity to potential receptors
(Data gaps are currently being addressed by Duke Energy and their findings
will be presented to the DEQ in supplemental reports.)

ROXBORO STEAM ELECTRIC PLANT RISK
CLASSIFICATION
Surface Water Key Factor:
100-year floodplain.
The impoundment is not located within the
• East Ash Pond. Low risk. The CCR
impoundment is not located within a
100 year floodplain.
• West Ash Pond. Low risk. The
footprint of the CCR impoundment a
natural drainage way.
• Unnamed Eastern Extension
Impoundment. Low risk. The CCR
impoundment is sited in a natural
drainage way, it is sited along a
reservoir and it is not located within a
100 year floodplain.
*The NC floodplain map depicts a 100-year flood elevations within the west CCR impoundment. The west CCR
impoundment and Hyco Lake flood elevations are predicted to be 462 and 413 feet above sea level, respectively.
However, this ash basin is contained by a stream valley embankment (dam) with a discharge canal that conveys
wastewater from the ash basin to Hyco Lake.
