Class I Facility
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please
review this draft carefully to ensure thorough understanding of the requirements and conditions
it contains. There are several changes from the existing permit, including the following:
• Proposed an external outfall 002 adjacent to outfall 001 to discharge cooling pond water
over the proposed emergency spillway during extreme rainfall events. Please note that
sampling requirements are waived for this outfall due to unsafe conditions during
extreme weather situations.
• Proposed a new internal outfall 001 A at the ash pond to discharge interstitial water to the
cooling pond during dewatering operations and added effluent limitations and monitoring
requirements. See condition A.(3).
• Proposed an internal outfall 115A to limit and monitor discharge from seven toe drains
and added effluent limitations and monitoring requirements. See condition A.(4).
• Proposed changes at outfall 001:
i. Added limits for oil & grease and TSS at outfall 001 as per 40 CFR 423.
ii. Added monitoring of effluent and instream hardness to collect site specific
effluent and instream data to analyze limitation and monitoring requirements for
hardness dependent metals.
iii. Added monitoring for total dissolved solids as per the recommendation of US
EPA.

iv. Added monitoring for total nitrogen, nitrate & nitrite, total kjeldahl nitrogen and
total phosphorus as per 15A NCAC 213.0508.
V. Removed monitoring for iron as it is no longer a parameter of concern for the
effluent from coal ash facilities.
vi. Added discharge limit and monitoring for mercury as it is a parameter of concern
for the effluent from coal ash facilities.
vii. Added monitoring for naphthalene and total phenols as they are parameters of
concern for discharges from fuel oil remediation system at the facility.
viii. Added monitoring of turbidity, chlorides, sulfates, total cadmium, total
chromium, total lead, total zinc and total thallium upon commencement of
dewatering of ash pond as they are parameters of concern for discharges from
coal ash facilities.
ix. Added discharge limits for arsenic upon commencement of dewatering as it
showed reasonable potential to violate water quality criteria of Lumber River
X. Removed monitoring for copper in cooling pond water as it did not show
reasonable potential to violate water quality criteria/standards for Lumber River.
However, the permittee is required to monitor copper upon commencement of
dewatering as it is one of the parameters of concern for discharges from coal ash
facilities.
A. (7) Biocide condition was changed for biocide used in cooling pond which was required
for cooling water systems in the previous permit.
Added following special conditions to the permit to be consistent with other Duke Energy

Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1
The permittee shall report discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:

If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements
may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1.1,
2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be submitted to
the mailing address above. See "How to Request a Waiver from Electronic Reporting" section
below.
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
Starting on December 21, 2020, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
Sewer Overflow/Bypass Event Reports;
Pretreatment Program Annual Reports; and
Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time
of each electronic submission. The permittee should use the EPA's website resources to identify
the initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the
entity (EPA or the state authorized by EPA to implement the NPDES program) that is the
designated entity for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at: http://www2.gpa. ovg /compliance/final-national-pollutant-
discharge-elimination-system-npdes-electronic-reporting-rule.
Electronic submissions must start by the dates listed in the "Reporting Requirements" section
above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers must be submitted in writing to
Page 10 of 14

Permit NC0005363
the Division for written approval at least sixty (60) days prior to the date the facility would be
required under this permit to begin submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring
data and reports shall be submitted electronically to the Division unless the permittee re -applies for
and is granted a new temporary electronic reporting waiver by the Division. Approved electronic
reporting waivers are not transferrable. Only permittees with an approved reporting waiver request
may submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
http://dM.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements (Supplements Section B. (11.) (b) and Supersedes Section B. (11.)
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part
II, Section B. (I 1.)(a) or by a duly authorized representative of that person as described in Part II,
Section B. (11.)(b). A person, and not a position, must be delegated signatory authority for eDMR
reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North
Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit
the following web page:
http://deg.nc.gov/about/divisions/water-resources/edmr
Certification. Any person submitting an electronic DMR using the state's eDMR system shall
make the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF
CERTIFICATION WILL BE ACCEPTED:
"I certify, under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or
persons who manage the system, or those persons directly responsible for gathering the
information, the information submitted is, to the best of my knowledge and belief, true, accurate,
and complete. I am aware that there are significant penalties for submitting false
information, including the possibility of fines and imprisonment for knowing violations. "
5. Records Retention [Supplements Section D. (6.)]
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR
submissions. These records or copies shall be maintained for a period of at least 3 years from the
date of the report. This period may be extended by request of the Director at any time [40 CFR
122.41].
