NPDES Permit Application
Riverbend Steam Station
Permit#: NC0004961
Gaston County
Dear Ms. Grzyb,
Duke Energy Carolinas, LLC (Duke Energy) hereby submits this NPDES permit renewal
package for the existing NPDES permit NC0004961. As mandated by North Carolina
Administrative Code 15A NCAC 2H.0105(e), this permit application for renewal is being
submitted at least 180 days prior to expiration of the current permit.
Electric power generation operations ceased on April 1, 2013 at the Riverbend facility. The
facility is in the process of completing post-closure activities. Demolition of the steam
generation plant is complete. Duke Energy completed excavation efforts of the primary and
secondary ash basins, ash stack and cinder pit at site on March 16, 2019. Duke Energy
anticipates the potential for future groundwater extraction and/or remediation activities on the
site and requests continued coverage under this existing permit for those activities as further
described in this submittal.
Due to the discontinuing of all steam generation processes at the Riverbend facility, Duke
Energy requests the following modifications to the new permit:
1. Condition A. (1), Outfall 001 - Removal of Outfall 001. All plant structures associated
with the steam generation plant were decommissioned and demolished. The Riverbend
facility no longer operates a plant chiller system. This condition is no longer applicable
to the site.
2. Condition A. (2), Outfall 002 - Removal of Outfall 002. The excavation of the ash basin
was completed in accordance with the North Carolina Coal Ash Management Act
(CAMA) of 2014, HB 630 of 2016 and the Senate Bill 716: Mountain Energy Act of
2015. None of the discharges associated with historic fa
cility acility operations will continue
due to the decommissioning of the plant, therefore this condition is no longer applicable
to the site. The groundwater remediation system discharge (GW Remediation Oil/Water
Separator system) was removed in approximately 2001. Duke Energy also requests the

Page 2
removal of conditions, A.5 throughA.15, associated with the former plant and ash basin
operations.
3. Condition A. (4), Outfall 002A—Discharge from the yard sump overflow will no longer
be discharged from Outfall 002A. The yard sump overflow was removed along with the
site decommissioning. Duke Energy requests the modification of this outfall to
accommodate focused groundwater extraction and discharge determined necessary after
the submittal of the Riverbend Groundwater Correction Action Plan (CAP) update.
(Additional information about specific characteristics of the potential future discharge
detailed in attachment 3).
4. Condition A. (10) - Groundwater Monitoring Well—Duke requests the removal of the
groundwater monitoring requirements to make the Riverbend permit consistent with other
Duke Site Permits. These compliance wells will continue to be monitored through the
CAMA groundwater monitoring program.
5. Condition A. (16)—Removal of Outfalls 101, 103, 104, 105, 106, 109, 110, 111, 112
which corresponds to seeps S-1, S-3, S-4, S-5, S-6, S-9, S-10, S-11, and S-12. This is
requested due to these flows having ceased. In accordance with the terms of Consent
Order EMC SOC WQ S 16-005, completion of the closure activities referenced in
subparagraph 1.f. of the consent order will eliminate the seeps from the ash basins at the
Riverbend Steam station. Only outfalls 102,107 and 108 still flow after excavation.
These flows meet all water quality standards and requirements in the SOC. Duke Energy
is requesting continued coverage for these flows to be assured they are covered, if
needed, in the interim however, Duke Energy believes the best way to handle these flows
is in accordance with the procedure used for Duke Energy coal fired permits in North
Carolina issued subsequent to the Riverbend permit. Duke requests concurrence that
these remaining flows, previously identified as wastewater seeps, can be addressed in site
Corrective Action Plans, as needed, and continuing NPDES permit coverage is not
needed. Attachment 5, is analytical data from seep sampling from 2017 —2019. Upon
receiving concurrence that these flows can be addressed in the CAP for the site, Duke
Energy would withdraw request for continuing coverage of outfall 102, 107 and 108.
6. Duke Energy requests removal of Appendix A, "Plan for identification of new
discharges" to make the Riverbend permit consistent with other Duke Energy permits.
7. Duke Energy requests inclusion of a groundwater compliance boundary map in the
reissued permit.
Please find enclosed in triplicate, the renewal application, which includes the following items:
• EPA Form 1
• EPA Form 2C
• Attachment 1 —NPDES Outfalls Map
• Attachment 2—Form 2C Item IIA Flow Diagram

CONTINUED FROM PAGE 3 OF FORM 2-C NC0004961 002A
PART C- If you are a primary industry and this outfall contains process wastewater,refer to Table 2c-2 in the instructions to determine which of the GC/MS fractions you must test for. Mark"X"in column 2-a for all such GC/MS
fractions that apply to your industry and for ALL toxic metals, cyanides,and total phenols. If you are not required to mark column 2-a(secondary industries, nonprocess wastewater ouffalls, and nonrequired GC/MS
fractions), mark"X"in column 2-b for each pollutant you know or have reason to believe is present. Mark"X"in column 2-c for each pollutant you believe is absent. If you mark column 2a for any pollutant,you must
provide the results of at least one analysis for that pollutant.If you mark column 2b for any pollutant,you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be
discharged in concentrations of 10 ppb or greater.If you mark column 2b for acrolein,acrylonitrile,2,4 dinitrophenol,or 2-methyl-4,6 dinitrophenol,you must provide the results of at least one analysis for each of these
pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater.Otherwise,for pollutants for which you mark column 2b,you must either submit at least one analysis or
briefly describe the reasons the pollutant is expected to be discharged. Note that there are 7 pages to this part; please review each carefully. Complete one table(all 7 pages)for each outfall.See instructions for
additional details and requirements.

PART C- If you are a primary industry and this outfall contains process wastewater,refer to Table 2c-2 in the instructions to determine which of the GC/MS fractions you must test for.Mark"X"in column 2-a for all such GC/MS
fractions that apply to your industry and for ALL toxic metals,cyanides, and total phenols. If you are not required to mark column 2-a(secondary industries, nonprocess wastewater outfalls, and nonrequired GC/MS
fractions), mark"X"in column 2-b for each pollutant you know or have reason to believe is present. Mark"X"in column 2-c for each pollutant you believe is absent. If you mark column 2a for any pollutant, you must
provide the results of at least one analysis for that pollutant.If you mark column 2b for any pollutant,you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be
discharged in concentrations of 10 ppb or greater.If you mark column 2b for acrolein,acrylonitrile,2,4 dinitrophenol,or 2-methyl-4,6 dinitrophenol,you must provide the results of at least one analysis for each of these
pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater.Otherwise,for pollutants for which you mark column 2b,you must either submit at least one analysis or
briefly describe the reasons the pollutant is expected to be discharged. Note that there are 7 pages to this part; please review each carefully. Complete one table(all 7 pages)for each outfall. See instructions for

PART C- If you are a primary industry and this outfall contains process wastewater,refer to Table 2c-2 in the instructions to determine which of the GC/MS fractions you must test for.Mark"X"in column 2-a for all such GC/MS
fractions that apply to your industry and for ALL toxic metals, cyanides,and total phenols. If you are not required to mark column 2-a(secondary industries, nonprocess wastewater outfalls, and nonrequired GC/MS
fractions),mark"X"in column 2-b for each pollutant you know or have reason to believe is present. Mark"X"in column 2-c for each pollutant you believe is absent. If you mark column 2a for any pollutant,you must
provide the results of at least one analysis for that pollutant.If you mark column 2b for any pollutant,you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be
discharged in concentrations of 10 ppb or greater.If you mark column 2b for acrolein,acrylonitrile,2,4 dinitrophenol,or 2-methyl-4,6 dinitrophenol,you must provide the results of at least one analysis for each of these
pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater.Otherwise,for pollutants for which you mark column 2b,you must either submit at least one analysis or
briefly describe the reasons the pollutant is expected to be discharged. Note that there are 7 pages to this part; please review each carefully. Complete one table(all 7 pages)for each outfall.See instructions for

LABORATORY FLAGS
< -concentration not detected at or above the adjusted reporting limit.
A - Federal MCL.
*- Interim Maximum Allowable Concentrations(IMACs)of the 15A NCAC 02L Standard,Appendix 1,April 1, 2013.
lg- Result confirmed by second analysis performed out of hold.
2g-The concentration in the Blank QC is less than the reporting limit but greater than 1/2 the reporting limit.
B-Target analyte detected in method blank at or above the reporting limit. Target analyte concentration in sample is less than 10X the
concentration in the method blank. Analyte concentration in sample could be due to blank contamination.
B1 -Target analyte detected in method blank at or above the reporting limit. Target analyte concentration in sample was greater than
l0X the concentration in the method blank. Analyte concentration in sample is not affected by blank contamination.
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.
B4-Target analyte was detected in Continuing Calibration Blank(s)at or above the reporting limit.
B5-Target analyte was present in blank(s)above the method detection limit but less than the reporting limit. Data is valid for
compliance purposes.
B6-Target analyte was detected in Continuing Calibration Blank(s) at a concentration greater than the reporting limit.
BC-The same analyte was detected in an associated blank at a concentration above 1/2 the reporting limit but below the
laboratory reporting limit.
CO- Result confirmed by second analysis.
CR-The dissolved metal result was greater than the total metal result for this element. Results were confirmed by reanalysis.
CU -The continuing calibration for this compound is outside of Pace Analytical acceptance limits. Analyte presence below reporting limits
in associated samples. Results unaffected by high bias.
D3 -Sample was diluted due to the presence of high levels of non-target analytes or other matrix interference.
D4-Sample was diluted due to the presence of high levels of target analytes.
D6-The precision between the sample and sample duplicate exceeded laboratory control limits.
E-Analyte concentration exceeded the calibration range. The reported result is estimated.
H -Sample analyzed past the recommended holding time.
H1 -Analysis conducted outside the EPA method holding time.
H2- Extraction of preparation conducted outside EPA method holding time.
H3-Sample was received or analysis requested beyond the recognized method holding time.
H6-Analysis initiated outside of the 15 minute EPA required holding time.
HS- Results are from sample aliquot taken from VOA vial with headspace(air bubble greater than 6 mm diameter).
j+ - Estimated concentration, biased high.
Ll -Analyte recovery in the laboratory control sample(LCS) was above quality control (QC) limits. Results may be biased high.
L2-Analyte recovery in the laboratory control sample(LCS)was below QC limits. Results for this analyte in associated samples may be
biased low.
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.
M - Matrix spike/ matrix spike dup failure.
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.
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.
P2- Re-extraction or re-analysis could not be performed due to insufficient sample amount.
P4-Sample field preservation does not meet EPA or method recommendations for this analysis.
P8-Analyte was detected in the method blank. All associated samples had concentrations of at least ten times greater than the blank
or were below the reporting limit.
RO-The data are unusable.The sample results are rejected due to serious deficiencies in meeting QC criteria. The analyte may or may
not be present in the sample.
R1 - Relative Percent Difference(RPD)value was outside control limits.
S-Associated calibration check did not meet specified criteria.
S1 - Data review findings indicate result may be unreliable. Use with caution.
U-Analyte was analyzed for, but not detected above the MDC.
