SIC Code 4911
Dear Mr. Grant:
Enclosed with this letter is a copy of the draft permit renewal and modification for your facility. Please
review this draft carefully to ensure thorough understanding of the conditions and requirements it
contains. There are several changes from the existing permit, including the following:
• Effluent Limits and Monitoring Requirements were added for Outfall 001 (Phase II) for the
dewatering and groundwater remediation wastewaters to be discharged after decanting of the
active ash basin is completed. See condition A. (2).
• Effluent Limits and Monitoring Requirements were added for Outfall 001 for the groundwater
remediation and landfill leachate wastewaters to be discharged after dewatering of the active ash
basin is completed. This effluent page for Outfall 001 (Phase III) becomes effective with the
commencement and discharge of landfill leachate. See condition A. (3).
• New Outfall effluent pages were added for ash basin seeps: 101A LOLA,101B LOLA,102,109,118,
125,126,103A, and 128. See conditions A. (7.) through A. (15.).
• New Outfall effluent pages were added for cooling pond seeps: CPS -201, CPS -202, CPS 203, CPS -
204, CPS -205, CPS -215, CPS -216, CPS -207, CPS -208, CPS -209, CPS -217, CPS -218, CPS -219, CPS -220,
and CPS -221. See conditions A. (16.) through A. (30.). -
• Effluent Limits and Monitoring Requirements were revised for Outfall 002 as follows:
o BOD and fecal coliform monitoring were added since sanitary wastewaters discharge to
the cooling pond.
o Monitoring and limitations were added for total chromium, total zinc, free available
chlorine, total residual chlorine and no detectable amount of the 126 Priority Pollutants per
Effluent Guidelines 40 CFR 423.13 (d)(1) for cooling tower blowdown discharges.
o The Reasonable Potential Analysis based on limited data from outfall 002 effluent showed
molybdenum as a pollutant of concern. Molybdenum monitoring was added to the
monitoring requirements.
o A review of the cooling pond seep data showed arsenic, lead, mercury and fluoride, were
pollutants of concern, therefore, monitoring for these parameters was added to Outfall 002.

o The daily limitation for total suspended solids was reduced to 50 mg/L per Effluent
Guidelines 40 CFR 423.12 (b)(9) since coal pile runoff has been discharged to the cooling
pond for many years.
See condition A.(4.).
• Effluent Limits and Monitoring Requirements were added for Duke Energy's proposed cooling
pond Outfall to be constructed at the breach. See A. (5.) Effluent Limitations and Monitoring
requirements for Outfall 002A. The limitations and monitoring requirements are the same as
Outfall 002 except a discharge shall only occur during severe weather events or required
maintenance.
• Effluent Limits and Monitoring Requirements were revised for Outfall 003 as follows:
o Monitoring and limitations were added for total chromium, total zinc, free available
chlorine, total residual chlorine and no detectable amount of the 126 Priority Pollutants
per Effluent Guidelines 40 CFR 423.13 (d)(1) for cooling tower blowdown discharges.
o The Reasonable Potential Analysis based on limited data from Outfall 003 effluent
showed the maximum predicted concentration for selenium was greater than 50% of the
allowable discharge concentration. Selenium monitoring was maintained.
o Pollutants of concern for Outfall 002 (total arsenic; total lead, total molybdenum, and
fluoride) were added since Duke Energy has requested the option of discharging many of
the same waste streams to Outfall 003.
See condition A.(5.).
• Special Condition A. (10.) Total Nitrogen Reopener Clause, in the existing permit, was eliminated
since this facility is now classified as "non -nutrient bearing".
• Special Condition A. (11.) Selenium Reopener Clause, in the existing permit, was eliminated since
the closure of the coal-fired steam electric plant is complete.
• Special Condition A. (43) Ash Pond Closure was added to the permit to facilitate the
decommissioning of the ash ponds.
• Special Condition A. (44) Instream Monitoring was added to the permit to monitor the impact of
the discharges on the receiving stream.
• Special Condition A. (46) Applicable State Law was added to the permit to meet the requirements
of Senate Bill 729 (Coal Ash Management Act).
• Special Condition A. (47) Domestic Wastewater Treatment Plant was added to the permit to assure
compliance with the 40 CFR 133.102.
• Special Condition A. (49.) Seep Pollutant Analysis was added to identify all seeps (ash pond seeps
and cooling pond seeps) and to list actions to be taken by the Permittee.
• The NC Division of Water Resources NPDES Permitting Unit is required to implement the new
dissolved metal standards in all permits public noticed after April 6, 2016. The new standards for
most metals include acute standards. Further, the freshwater standards for several metals are
expressed as the dissolved form of the metals, and seven metals have hardness -dependent
equations. As a result, the permit includes the requirement to sample for hardness at all outfall
and instream locations.
• Special Condition A. (40) was added to the permit regarding the submittal of all the required
information under 40 CFR 125.95 with the next permit application
• Starting December 21, 2016, federal regulations require electronic submittal of all discharge
monitoring reports (DMRs) and specify that, if a state does not establish a system to receive such
submittals, then permittees must submit DMRs electronically to the Environmental Protection
Agency (EPA). The final NPDES Electronic Reporting Rule was adopted and became effective on
December 21, 2015.
The requirement to begin reporting discharge monitoring data electronically using the NC
DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been added to

web site:
hl!p://www2.epa.gov/comphance/­final-national-poRutant-discharge-ehmination-system-
Lipdes-electronic-reportin&:Lule.
• The following special conditions were added to the permit to be consistent with other Duke
Energy permits: A. (38) Biocides, A. (32) Additional Conditions and Definitions, A. (50.) Chemical
Discharges, A.(45.) Fish Tissue Monitoring Near Ash Pond Discharge, A. (42.) Structural Integrity
Inspections of Ash Pond Dam.
In addition, and in accordance with Part H standard conditions C. 6., solids, sludges .... or other
pollutants removed in the course of treatment or control of wastewaters shall be utilized/ disposed of .....
in a manner such as to prevent any pollutant from such materials from entering waters of the state or
navigable waters of the United States. Therefore, solids from the Filter Plant filter press or equipment
cleanings shall not be disposed of in the cooling pond or via Outfall 003.
Concurrent with this notification the Division is publishing a notice in a newspaper having circulation in
the general Wayne County area, soliciting public comments on this permit draft. Please provide any
comments you may have to the DEQ - DWR, NPDES Program no later than 30 days after receiving this
draft permit.
Following the 30 -day public comment period, the Division will review all pertinent comments and take
appropriate action prior to issuing a final permit. If you have questions concerning this draft permit,
please call me at [phone] or by email at [e-mail].
