Section 1. Facility Activities and Process:
The Duke Energy Belews Creek Steam Station is a 2,200-megawatt coal-fired electricity generating
plant that came online in 1974. There are two (2)production units. The site contains the powerhouse
yard, coal storage yard, flue gas desulfurization(FGD) system, waste storage facility, limestone stacker,
gypsum stacker, FGD residual landfill, sanitary lagoon, dry ash landfill, scrubber wastewater treatment
system, ash settling basin, ammonia tank farm, and various storage and maintenance buildings.
Since the last permit renewal, the following significant changes have been made:
• Outfalls SWO10 and SW012 were rerouted to above ground tanks and no longer discharge.
• Narrative descriptions for SW015, SW018A, SW01813, SW019, and SW024 updated.
o SW015: Used Oil tank was removed from the description.
o SW018A: Drainage area updated from 3.0 to 6.1 acres based on contour data.
o SW018B: Drainage area updated from 40.2 to 42.9 acres based on contour data.
o SW019: Drainage area was updated from 3.0 to 34.2 acres based on contour data.
o SW024: The Percent Impervious was updated from 0%to 12%based on area
measurement of the pavement and guard house.
With the renewal application, Duke Energy requested:
• Removal of outfalls SW012, SW013, and SW014 as they no longer discharge after being
rerouted to an above ground storage tank.
o DEMLR response: SW012, SW013, and SW014 will be removed from the permit.

Additional drainage areas/stormwater outfalls onsite but not included in permit:
• Outfall SW001 (Drainage area 1): Drainage area consists of the station guard house, water tower,
parking lots, and railcar staging. A concrete trench containing the ash-sluice pipelines forms the
southern border of the drainage basin (any ash spillage would be contained within the trench).
There is no discharge outlet for this location. Per information submitted by Duke Energy in an
email dated 6/24/2016, this drainage area could potentially be impacted by CCR due to ash
hauling operations. Per information submitted by Duke Energy in an email dated 10/6/2022, this
is the same outfall as SW024 and there is no significant material stored in this area.
• Outfall SWO02 (Inactive; Drainage area 2): Drainage area consists of the retired smokestacks in
the northern portion of the plant yard adjacent to the FGD. The entire drainage area is paved or
roofed. The ash-sluice pipeline trench borders a portion of this drainage area(spills within the
trench would be contained). Raw lake water is used in the chiller system to cool the "center bay"
area of the plant, and the once through, non-contact water is discharged through this outfall.
Chemicals are not added to the cooling water. Per information submitted by Duke Energy in an
email dated 6/24/2016, this drainage area could potentially be impacted by CCR due to ash
hauling operations. This drainage area is covered under the wastewater permit (NCO024406).
• Outfall SWO08 (Drainage area 8): Drainage area consists of a wooded area. No industrial activity
takes place in this drainage area therefore stormwater permit coverage is not needed.
• Outfall SWO10 (Abandoned; Drainage area 10): Drainage area consists of gypsum radial stacker
area and limestone stockpile, 1,200 feet of gravel access roads, approximately 800 feet of
railroad tracks, a railcar unloader, paved parking lot, and laydown area. Potential pollutants
include limestone, gypsum, and metals. Currently stormwater runoff is pumped to the ash basin.
o Per additional information provided via email 10/6/2022: All stormwater runoff is
collected and treated at the stormwater basin in the north edge of the drainage area. The
basin contents are pumped to the ash basin. A concrete culvert spillway for the
stormwater basin is located beneath the access road. Any basin overflow would discharge
into Drainage Area 7 and then to Belews Lake. No overflow events have been recorded.
• Outfall SWO 18 (Drainage area 1 q Drainage area consists of undeveloped areas, approximately
800 feet of railway, and overflow from the south coal yard sump should the sump pumps
malfunction. Per previously issued permit, from the area east of the gravel parking area is an
internal outfall that does not directly discharge to surface water, and that in the reported
configuration mode a stormwater discharge permit is not required.
• Outfall SWO18B (Drainage area 18B):_Drainage area consists of structural fill, woodlands, and
approximately 600 feet of railway. The structural fill was capped with a synthetic liner and
gravel parking lot. Runoff accumulates in a stormwater detention pond, which has a riser and
skimmer. Outfall was removed from permit per DEQ letter dated 3/13/2017.
• Drainage area 19: Drainage area consists of runoff from the eastern portion of the railroad tracks,
approximately 2,300 feet of railroad tracks, and retention pond. Stormwater runoff collects in the
pond until it evaporates. Per the previously issued permit, no industrial activity takes place in the
area west of the gravel parking area draining to this outfall, therefore stormwater permit
coverage is not needed.
• Outfall SW020 (Drainage area 20): Per the previously issued permit, FGD landfill operations are
pumped to the ash basin, therefore stormwater permit coverage is not needed.
• Outfall SW021 (Drainage area 21): Per the previously issued permit, FGD landfill operations are
pumped to the ash basin, therefore stormwater permit coverage is not needed.
Page 5 of 16

• Outfall SW023 (Drainage area 23): Per the previously issued permit, the ammonia tank farm and
ash storage dome are pumped to the ash basin, therefore stormwater permit coverage is not
needed.
• Outfall SW024 (Drainage area 24): Drainage area consists of approximately 600 feet of paved
road and a grassy berm. No industrial activity occurs in the drainage area, therefore stormwater
permit coverage is not needed. Per information submitted by Duke Energy in an email dated
6/24/2016, this drainage area could potentially be impacted by CCR due to ash hauling
operations. Per information submitted by Duke Energy in an email dated 10/6/2022, this is the
same outfall as SW001 and there is no significant material storage in this area.
• Outfall SW025 (Drainage area 25): Per the 2017 issued permit, the warehouse and covered waste
storage area sheet flows and does not discharge through a point source, therefore stormwater
permit coverage is not needed.
• Outfall SW026 (Drainage area 26): Drainage area consists of vegetated area with a series of
stormwater basins south of the FGD landfill. The drainage area does not come in contact with
any significant materials. Per previously issued permit, the drainage area consist of the FGD
residuals landfill, with no industrial activity taking place in this drainage area, therefore
stormwater permit coverage is not needed.
Why Industrial Sites with Stormwater are Subject to a Permit: Federal NPDES regulations define
stormwater discharge associated with industrial activity in 40 CFR §122.26 (b)(14) as: "the discharge
from any conveyance that is used for collecting and conveying storm water and that is directly related to
manufacturing,processing or raw materials storage areas at an industrial plant. The term does not
include discharges from facilities or activities excluded from the NPDES program under this part 122.
For the categories of industries identified in this section, the term includes, but is not limited to, storm
water [sic] discharges from industrial plant yards; immediate access roads and rail lines used or traveled
by carriers of raw materials, manufactured products, waste material, or byproducts used or created by
the facility; material handling sites; refuse sites; sites used for the application or disposal of process
waste waters (as defined at part 401 of this chapter); sites used for the storage and maintenance of
material handling equipment; sites used for residual treatment, storage, or disposal; shipping and
receiving areas; manufacturing buildings; storage areas (including tank farms) for raw materials, and
intermediate and final products; and areas where industrial activity has taken place in the past and
significant materials remain and are exposed to storm water. For the purposes of this paragraph, material
handling activities include storage, loading and unloading, transportation, or conveyance of any raw
material, intermediate product, final product, byproduct or waste product. The term excludes areas
located on plant lands separate from the plant's industrial activities, such as office buildings and
accompanying parking lots as long as the drainage from the excluded areas is not mixed with storm
water [sic] drained from the above described areas."

Quantitative sampling included pH, TSS, O&G, boron, antimony, arsenic, beryllium, cadmium,
chromium, copper, lead, nickel, selenium, silver, thallium, zinc, mercury, and PCBs.
Parameters are based on potential pollutants in the drainage area, sampling results, and in some cases,
dependent upon future activities (e.g., ash removal through the drainage area). Below is a table of the
proposed monitoring for each outfall at the Belews Creek Steam Station site.

Stormwater Benchmarks and Tiered Response: Rather than limits,North Carolina NPDES
Stormwater permits contain benchmark concentrations. Stormwater benchmarks are numerical action
levels for stormwater monitoring. Benchmarks are not effluent limits, and benchmark exceedances are
not permit violations. Benchmarks provide facilities a tool for assessing the significance of pollutants in
stormwater discharges and the effectiveness of best management practices (BMPs). Benchmark
concentrations are intended as guidelines for the facility's development and implementation of the
Stormwater Pollution Prevention Plan(SWPPP).
Benchmark exceedances require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater BMPs in a tiered program. The permit establishes a
tiered approach to specify actions the permittee must take in response to analytical results above
benchmark concentrations. The tiered structure of the permit provides the permittee and DEMLR wide
flexibility to address issues that may arise with one or more parameters and/or outfalls.
Page 10 of 16

Metals benchmarks are calculated to mimic acute water quality standards and with the guidance of
DWR. NC DWR follows established federal procedures for calculating acute standards when developing
the benchmarks. Just like the acute standards, metals benchmarks normally reflect one half of the
calculated Final Acute Value (the "1/2 FAV"). In most cases, translation into total recoverable values is
based on an assumed hardness of 25 mg/L and a total suspended solids (TSS) concentration of 10 mg/L.
Acute standards protect aquatic life from negative impacts of short-term exposure to higher levels of
chemicals where the discharge enters a waterbody. The Stormwater Permitting Program applies this
approach because of the ephemeral nature of rainfall events.
The Division may evaluate results to determine if a smaller suite of parameters for some outfalls is
adequate to characterize potential pollution or BMP effectiveness. For example, one or more metals or
other parameters may serve as an adequate tracer for the presence of ash pollution during disturbance or
ash removal in specific drainage areas at this site. For parameters that do not have a stormwater
benchmark, the Division may develop a benchmark value if appropriate toxicity data become available
or if rising trends in concentrations suggest a persistent source.
A summary of the benchmarks in the draft permit, and their basis, is below:

Stormwater Pollution Prevention Plan: The proposed permit conditions reflect the EPA and NC's
pollution prevention approach to stormwater permitting. The Division's maintains that implementation
of Best Management Practices (BMPs) and traditional stormwater management practices that control the
source of pollutants meets the definition of Best Available Technology (BAT) and Best Conventional
Pollutant Control Technology(BCT). The permit conditions are not numeric effluent limitations but are
designed to be flexible requirements for implementing site-specific plans to minimize and control
pollutants in stormwater discharges associated with the industrial activity. Title 40 Code of Federal
Regulations (CFR) §122.44(k)(2) authorizes the use of BMPs in lieu of numeric effluent limitations in
NPDES permits when the agency finds numeric effluent limitations to be infeasible. The agency may
also impose BMP requirements which are "reasonably necessary" to carry out the purposes of the Act
under the authority of 40 CFR 122.44(k)(3). The conditions proposed in this draft permit are included

under the authority of both of these regulatory provisions. In essence, the pollution prevention and BMP
requirements operate as limitations on effluent discharges that reflect the application of BAT/BCT.
Mercury Monitoring Requirements: The proposed permit requires mercury to be measured in
stormwater samples by EPA Method 1631 E, which can detect levels as low as 0.5 ng/l. This requirement
is consistent with recent federal rule-making that requires NPDES permittees to monitor discharges with
sufficiently sensitive test procedures approved under 40 CFR §136. Modifications to 40 CFR §122.44(i)
require a method that has a minimum level (ML) at or below the effluent limit(not applicable here), or
the lowest minimum level (ML) of EPA approved analytical methods for the measured parameter. Based
on results, Method 1631E will be required to quantify levels in these discharges. NC DEMLR
understands that this method is more costly and requires a more intensive sampling protocol than most
other parameters, and that fish tissue sampling will be provided during the permit cycle. Therefore, no
benchmark applies that would trigger tiered response actions. Proposed permit provisions also allow the
permittee to use field blank and/or method blank concentrations to adjust reported mercury levels as
long as documented is submitted with the Data Monitoring Report DMR).
Flexibility in Tier Responses: Tier Two actions provide an opportunity for the permittee to propose an
alternative monitoring plan for approval by the Region:
• Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances,
exercise the option of contacting the DEMLR Regional Engineer as provided below in Tier
Three. The Regional Engineer may direct the response actions on the part of the permittee as
provided in Tier Three, including reduced or additional sampling parameters or frequency.
• If pursuing the alternative above after two consecutive exceedances, the permittee may propose
an alternative monitoring plan for approval by the Regional Engineer.
The permit therefore allows the permittee to petition the Regional Office for monitoring changes sooner
than Tier Three (upon any four benchmark exceedances) and gives guidance on one option to take. For
example, the permittee may request that mercury only be monitored semi-annually under the tiers, or
that only parameters over the benchmark be monitored more frequently. In this way, changes to the
monitoring scheme for any outfall could be handled outside of a permit modification.
Other Proposed Requirements:
• It is standard for Stormwater Pollution Prevention Plan(SWPPP)requirements to include an
annual certification that stormwater outfalls have been evaluated for the presence of non-
stormwater discharges, and if any are identified, how those discharges are permitted or otherwise
authorized.
• Requirement to submit a request for permit modification if the facility identifies or creates any
new outfalls, removes outfalls, or alters any drainage area that changes potential pollutants.
• The Division expects the permittee to apply best professional judgment and consider the safety
of its personnel in fulfilling sampling obligations under the permit.
• Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). If a
state does not establish a system to receive such submittals, then permittees must submit DMRs
electronically to the EPA.
• Quarterly QualitativeNisual Monitoring to assure regular observation of outfalls throughout
year.

Section 4. Changes from previous permit to draft:
• Monitoring increased from semi-annually to quarterly for all parameters (qualitative and
quantitative)
• "No discharge" clarifications made
• eDMR requirement added
• Feasibility study requirement removed per updated stormwater program requirements
• Boilerplate language moved into body of the permit; boilerplate no longer attached
• Monitoring for total hardness added for all outfalls where monitoring for hardness dependent
metals is required
• Benchmarks updated for parameters per guidance from DWR Standards group on stormwater
benchmarks
• Non-Polar Oil & Grease and New motor oil usage monitoring added for all outfalls as standard
monitoring requirement in stormwater permits
• Benchmark and tiered response requirements have been added for all mercury monitoring.
• Outfalls SW001 and SW024 have been removed as no industrial activity takes place in the
drainage areas
• Outfall SW018B has been removed per DEQ letter dated 3/13/2017
• Outfall SW030 has been added to the permit per permittee's request
• PCB monitoring removed from the permit for outfalls SW003, SW004, SW005, SW006,
SW009, SWO11, SW015, SW016, and SW017 per the footnotes in the previous permit
• Monitoring for coal ash constituents added for outfalls SWOT I and SW015 due to exposure
potential
• Monitoring for BOD, COD, chromium, copper, lead, and zinc added to outfalls SW007, SW016,
SW017, SW018A, and SW022 due to items stored in laydown areas
• Total hardness added for outfalls SW007, SW016, SW017, SW018A, and SW022 as monitoring
for hardness dependent metals required
• Outfall SW031 added to permit per permittee's request
Section 5. Changes from draft to final:
• Monitoring for SW012, SW013, and SW014 has been added based on information provided by
the permittee
Section 6. Discussions with the Facility and Regional Office:
• Initial contact with facility: 8/17/2022
• Initial contact with Regional Office: 8/17/2022
• Draft sent to CO peer review: 11/9/2022
• Draft sent to Regional Office: 4/17/2023
• Final permit sent for supervisor signature: 5/26/2023

Section 7. Comments received on draft permit:
• Ben Kirby (DEQ PWS; via email 4/24/2023): Our Office concurs with the issuance of this
permit provided the facility is operated and maintained properly, the stated effluent limits are
met prior to discharge (if applicable), and the discharge does not contravene the designated water
quality standards.
• Lori Tollie (Duke Energy; via email 5/17/2023): Request removal of SW007 since this
discharge is uncontaminated groundwater(see supplemental information from the annual non-
stormwater inspection).
o DEMLR Response:
■ Per information provided in the draft permit comments, Outfall SW007 has
similar industrial activities in the drainage area as Outfalls SW016, and SW017,
SW018A, and SW022, which require monitoring. Please provide further
explanation as to why you feel monitoring for SW007 should be removed.
■ The draft permit comments have Outfalls SW012, SW013, SW014, and SW024
identified as having discharge. In information provided to the Division during the
permit renewal process, Outfalls SW012, SW013, and SW014 were stated as
having no discharge since they were routed to oil trap tanks that went to the FGD
scrubber make-up system. Outfall SW024 (the same as Outfall SW001) was
stated as having no industrial activity in the drainage area, however, the draft
permit comments mark the drainage area as having rail activity/coal haul. Please
clarify what industrial activities occur in each of these drainage areas.
o Lori Tollie (via email 5/23/2023):
■ Stormwater outfall SW007 does have industrial activity in its drainage area(inert
laydown/storage and parking) similar to SW016, SW017, SW018A, and SW022.
The difference in outfall SW007 is that it flows year around even outside of any
rain event. Cardno has indicated that the flow from SW007 is groundwater. Any
drainage from the transformers was rerouted to the FGD scrubber makeup system.
However, there is a drain near outfall SW013 that does have flow when it rains.
We agree that SW012, SW013, and SW014 should remain in permit until all flow
from SW013 is stopped.
■ Flow to SW024 was rerouted with the process water redirect project to prevent
anything related to coal from leaving the drainage area. All drains around the
coal yard or Ammonia tank farm area flow to the concert ditch that is then treated
at the lined retention basin. SW030 catches any flow from the other drains around
FGD wastewater treatment area. The flow that does not go to the concert ditch
surrounding coal pile goes to the ditches that flow back to the consolidated sump
and then treated through the wastewater treatment system.
o DEMLR Response (via email 5/25/2023):
■ For clarity on Outfall SW007, I understand the outfall discharges during non-rain
days, but when it does rain, does rainwater come into contact with the industrial
activity occurring in the drainage area and discharge through outfall SW007?
■ Outfalls SW012, SW013, and SW014 currently do not require monitoring in the
draft permit. Based on the comments provided, the permit will be amended to add
monitoring for these outfalls. Please confirm the potential pollutants and
industrial activity in each of these drainage areas.
o Lori Tollie (via email 5/25/2023): Any precipitation that falls within the drainage area of
outfall SW007 would come into contact with industrial activity.
Page 15 of 16

o DEMLR Response (via email 5/26/2023): As precipitation has the potential to come into
contact with industrial activity, outfall SWO07 will remain in the permit with monitoring.

SW007?
Outfalls SW012, SW013, and SWO14 currently do not require monitoring in the draft permit. Based on the comments

to SW016,SW017, SW018A, and SW022.The difference in outfall SWO07 is that it flows year around even outside of any
rain event. Cardno has indicated that the flow from SWO07 is groundwater. Any drainage from the transformers was
rerouted to the FGD scrubber makeup system. However,there is a drain near outfall SWO13 that does have flow when it
rains. We agree that SW012, SWO13, and SWO14 should remain in permit until all flow from SWO13 is stopped.
Flow to SW024 was rerouted with the process water redirect project to prevent anything related to coal from leaving
the drainage area. All drains around the coal yard or Ammonia tank farm area flow to the concert ditch that is then
treated at the lined retention basin. SWO30 catches any flow from the other drains around FGD wastewater treatment
area. The flow that does not go to the concert ditch surrounding coal pile goes to the ditches that flow back to the
consolidated sump and then treated through the waste water treatment system.
Please let me know if you have further questions.

Good afternoon,
Thank you for submitting comments on the draft permit. Please see below for a few follow-up questions.
• Per information provided in the draft permit comments, Outfall SWO07 has similar industrial activities in the
drainage area as Outfalls SW016, and SW017, SW018A, and SW022,which require monitoring. Please provide
further explanation as to why you feel monitoring for SWO07 should be removed.
• In the draft permit comments, Outfalls SW012, SWO13, SWO14, and SW024 are identified as having discharge. In
information provided to the Division during the permit renewal process, Outfalls SW012, SWO13, and SWO14
1

were stated as having no discharge since they were routed to oil trap tanks that went to the FGD scrubber
make-up system. Outfall SW024(the same as Outfall SW001)was stated as having no industrial activity in the
drainage area, however,the draft permit comments mark the drainage area as having rail activity/coal haul.
Please clarify what industrial activities occur in each of these drainage areas.
Thank you,

Thank you, Lori. Would it be possible to get a description of the expected industrial activity that will occur in the
drainage area?This way I know what required monitoring to put in the permit for the outfall.The BMP summary can
come at a later date. If things change after the basins are built,you can submit a modification request at that time and
we can address any monitoring changes needed.
An alternative is to just exclude the new outfall from the current draft permit and you can submit a modification request
in the future once the basins are built. Please let me know.
Thank you,

Hi Brianna,
I have removed Jessica Bednarcik from this email communication as she is our Senior Vice President and not typically
copied on routine permit correspondence. I do not have the additional information you requested concerning SW031
(former outfall 003) at this time. Cardno is putting the information package together on behalf of Duke Energy. I should
have this information to you next week, so hopefully this will work for you to include this new outfall in the permit
renewal. Also, Belews Creek had an onsite inspection with Lily Kay and Nate Gainer on Thursday October 13t".They had
given us some suggestions to make our permit application more accurate.
They offered the following suggestions:
• Renew tier relief for Outfalls SW003,SW004, SW005 and include SW006 since it's in the same drainage area and
experiences the same industrial activities. SW006 has been in tier status since the issuances of the permit in
2017. Recommended we sample from roof drains and background in the area of these outfalls to verify metals
contribution from roof drains/metal structures as well as background sampling. Recommended 1 sample per
month for 3 months.
• Remove Outfalls SW016 and SW017.These outfalls are associated with the switchyard are consistently under
the lake level and have not been sampled during the permit term. SW016 would be representative of SW017 if
sampling were possible.
• Remove Outfall SW015 as this drainage area has had no flow since early 2018.The oil storage tank has been
removed and replaced with a parking lot. There is storage for an empty spare transformer that sits in secondary
containment with a level alarm in this drainage area.
• Recommended we have an engineering firm review and certify that Outfall SW007 is groundwater and not
stormwater runoff. Cardno did an annual non stormwater inspection in April of this year determining that the
flow from SW007 is groundwater from a nearby spring. Inspection is attached.
Please let me know if you have any questions or concerns.Thank you

That numbering is fine. As this outfall is not marked in any previously submitted site maps or BMPs, please provide an
updated site map with this new outfall marked as well as a narrative description and BMP summary like that provided

I have one follow up question. Is repurposed Outfall 003 the new Outfall SW030 that was previously requested be added
to the permit? Or is Outfall 003 a separate, new outfall that needs a new number? If it needs a new number, please
assign an outfall number.

Hi Brianna,
1. The application references wanting to add a new outfall to the permit for discharge of upland flow
surrounding the ash basin. Which outfall is being referenced? We would like to repurpose the former
ash basin NPDES WW outfall 003 that discharges to an unnamed tributary to the Dan River. Latitude
36.3061, Longitude -80.0807
2. The application states outfalls SWO12 SW013, and SWO14 have been rerouted to ASTs. Where does the
flow go after it reaches the ASTs? Do the ASTs discharge, are they routed to wastewater treatment,
etc.? The ASTs go to the FGD scrubber make up systems and are not discharged.
3. Is outfall SWO10 pumped to the ash basin or ASTs? If to AST, where does it go after (see question
2). The original SWO10 was abandoned during the gypsum and limestone stacker construction. All
stormwater runoff from Drainage Area 10 is collected and treated at the stormwater basin in the north
edge of the drainage area. The basin contents are pumped to the ash basin. A double 24" diameter
concrete culvert spillway for the stormwater basin is located beneath the access road. Any basin
overflow would discharge into Drainage Area 7 and then into Belews Lake. To date, no overflow events
have been recorded.
4. Could outfalls SWO11 and SWO15 be impacted by CCR due to ash hauling operations? Information from
an email dated 6/24/2016 states this. Yes
S. Could outfalls SWO01 and SW024 be impacted by CCR due to ash hauling operations? Information from
an email dated 6/24/2016 states this, but the application says stormier permit coverage is not needed.
This area consists of a guard house, water tower, some rail car staging, and a parking areas. There is no
significant material storage in this area. Outfalls SWO01 and SW024 are the same outfall.
Please let me know if you have further questions and again my apologies for the delayed
response. Thank you

Good morning,
The Division of Energy, Mineral, and Land Resources (DEMLR) Stormwater Permitting Program
acknowledges receipt of your renewal application for coverage under NPDES Permit Number NCS000573.
Please continue to comply with all conditions and monitoring requirements in your current NPDES stormwater
permit. As long as you have submitted a complete renewal request package and maintain compliance with those
permit conditions, stormwater discharges from this facility are authorized by that permit until the Division
issues a renewal permit or notifies you of an alternative action.
I am working on renewing the individual stormwater permit for the Belews Creek Steam Station(NCS000573).
I need additional information in order to 1) confirm that the information I have is correct and 2) make sure the
permit adequately serves the needs of the facility. Please provide the following:
• Confirm the number of stormwater outfalls and associated coordinates;
• Confirm the status of stormwater outfalls SW001 and SW002;
• An electronic spreadsheet summarizing all of the monitoring data that has been collected since the
effective date of the current permit;
• Verification that the information in the renewal application is still complete and correct; and
• An explanation of any operational changes since the renewal application was submitted.
Enter your stormwater permit number into the Stormwater Permit Summary Report and you will see a form that
includes the address of the facility, contact information for the permit, and the regulated stormwater outfall(s)
for the facility. Please review the facility information to make sure it is correct. Information can be updated
using the links provided below, where applicable:
• Facility/Company name or ownership: Name/Ownership Change Form
• Owner Affiliation(Legally responsible person; i.e., someone with the company who is designated to
represent the company per signatory requirements or another authorized representative): Permit Contact

• Facility address only: Email Bethany Geor og ulias
• Stormwater outfall information: Email Bethanyy og ulias
• Visit the eDMR Six Steps website and complete Steps 1 and 2.
• Pay outstanding permit fees: Stormwater ePayment website

Once I have the above listed information, I can continue my review. You will receive a draft permit for a 30-day
comment period. During this time we will be able to address any comments or concerns you have. During the
same 30-day period, the draft will be sent to a Regional Office staff member for review as well as out to public
notice. Once all comments and concerns are addressed, you may be issued a final permit.
Please contact me if you have any questions.

in the future once the basins are built. Please let me know.

Hi Brianna,
Here is the map of the new proposed SW outfall 031 to the Dan River.The SW basins aren't built yet so I will have to
submit our BMP summary and narrative at a later date. Please let me know if you need anything else or would like to

Hi Brianna,
I have removed Jessica Bednarcik from this email communication as she is our Senior Vice President and not typically
copied on routine permit correspondence. I do not have the additional information you requested concerning SW031
(former outfall 003) at this time. Cardno is putting the information package together on behalf of Duke Energy. I should
have this information to you next week, so hopefully this will work for you to include this new outfall in the permit
renewal. Also, Belews Creek had an onsite inspection with Lily Kay and Nate Gainer on Thursday October 13t".They had
given us some suggestions to make our permit application more accurate.
They offered the following suggestions:
• Renew tier relief for Outfalls SW003,SW004, SW005 and include SW006 since it's in the same drainage area and
experiences the same industrial activities. SW006 has been in tier status since the issuances of the permit in
2017. Recommended we sample from roof drains and background in the area of these outfalls to verify metals
contribution from roof drains/metal structures as well as background sampling. Recommended 1 sample per
month for 3 months.
• Remove Outfalls SW016 and SW017.These outfalls are associated with the switchyard are consistently under
the lake level and have not been sampled during the permit term. SW016 would be representative of SW017 if
sampling were possible.
• Remove Outfall SW015 as this drainage area has had no flow since early 2018.The oil storage tank has been
removed and replaced with a parking lot.There is storage for an empty spare transformer that sits in secondary
containment with a level alarm in this drainage area.
• Recommended we have an engineering firm review and certify that Outfall SW007 is groundwater and not
stormwater runoff. Cardno did an annual non stormwater inspection in April of this year determining that the
flow from SW007 is groundwater from a nearby spring. Inspection is attached.
Please let me know if you have any questions or concerns.Thank you

Hello Lori,
I have one follow up question. Is repurposed Outfall 003 the new Outfall SW030 that was previously requested be added
to the permit? Or is Outfall 003 a separate, new outfall that needs a new number? If it needs a new number, please
assign an outfall number.

Hi Brianna,
1. The application references wanting to add a new outfall to the permit for discharge of upland flow
surrounding the ash basin. Which outfall is being referenced? We would like to repurpose the former
ash basin NPDES WW outfall 003 that discharges to an unnamed tributary to the Dan River. Latitude
36.3061, Longitude -80.0807
2. The application states outfalls SWO12 SW013, and SWO14 have been rerouted to ASTs. Where does the
flow go after it reaches the ASTs? Do the ASTs discharge, are they routed to wastewater treatment,
etc.? The ASTs go to the FGD scrubber make up systems and are not discharged.
3. Is outfall SWO10 pumped to the ash basin or ASTs? If to AST, where does it go after (see question
2). The original SWO10 was abandoned during the gypsum and limestone stacker construction. All
stormwater runoff from Drainage Area 10 is collected and treated at the stormwater basin in the north
edge of the drainage area. The basin contents are pumped to the ash basin. A double 24" diameter
concrete culvert spillway for the stormwater basin is located beneath the access road. Any basin
overflow would discharge into Drainage Area 7 and then into Belews Lake. To date, no overflow events
have been recorded.
7

4. Could outfalls SWO11 and SWO15 be impacted by CCR due to ash hauling operations? Information from
an email dated 6/24/2016 states this. Yes
5. Could outfalls SWO01 and SW024 be impacted by CCR due to ash hauling operations? Information from
an email dated 6/24/2016 states this, but the application says stormier permit coverage is not needed.
This area consists of a guard house, water tower, some rail car staging, and a parking areas. There is no
significant material storage in this area. Outfalls SWO01 and SW024 are the same outfall.
Please let me know if you have further questions and again my apologies for the delayed
response. Thank you

Good morning,
The Division of Energy, Mineral, and Land Resources (DEMLR) Stormwater Permitting Program
acknowledges receipt of your renewal application for coverage under NPDES Permit Number NCS000573.
Please continue to comply with all conditions and monitoring requirements in your current NPDES stormwater
permit. As long as you have submitted a complete renewal request package and maintain compliance with those
permit conditions, stormwater discharges from this facility are authorized by that permit until the Division
issues a renewal permit or notifies you of an alternative action.
I am working on renewing the individual stormwater permit for the Belews Creek Steam Station(NCS000573).
I need additional information in order to 1) confirm that the information I have is correct and 2) make sure the
permit adequately serves the needs of the facility. Please provide the following:
• Confirm the number of stormwater outfalls and associated coordinates;
• Confirm the status of stormwater outfalls SW001 and SW002;
• An electronic spreadsheet summarizing all of the monitoring data that has been collected since the
effective date of the current permit;
• Verification that the information in the renewal application is still complete and correct; and
• An explanation of any operational changes since the renewal application was submitted.
Enter your stormwater permit number into the Stormwater Permit Summary Report and you will see a form that
includes the address of the facility, contact information for the permit, and the regulated stormwater outfall(s)
for the facility. Please review the facility information to make sure it is correct. Information can be updated
using the links provided below, where applicable:

• Facility/Company name or ownership: Name/Ownership Change Form
• Owner Affiliation (Legally responsible person; i.e., someone with the company who is designated to
represent the company per signatory requirements or another authorized representative): Permit Contact
Update Request Form
• Delegation of Signature Authority (DOSA): Permit Contact Update Request Form
• Billing contact: Permit Contact Update Request Form
• Permit contact: Permit Contact Update Request Form
• Facility contact: Permit Contact Update Request Form
• Facility address only: Email Bethany Geor og ulias
• Stormwater outfall information: Email Bethany Geor_og ulias
• Visit the eDMR Six Steps website and complete Steps 1 and 2.
• Pay outstanding permit fees: Stormwater ePg3 ment website
Once I have the above listed information, I can continue my review. You will receive a draft permit for a 30-day
comment period. During this time we will be able to address any comments or concerns you have. During the
same 30-day period, the draft will be sent to a Regional Office staff member for review as well as out to public
notice. Once all comments and concerns are addressed, you may be issued a final permit.
Please contact me if you have any questions.

copied on routine permit correspondence. I do not have the additional information you requested concerning SW031
(former outfall 003) at this time. Cardno is putting the information package together on behalf of Duke Energy. I should
have this information to you next week, so hopefully this will work for you to include this new outfall in the permit
renewal. Also, Belews Creek had an onsite inspection with Lily Kay and Nate Gainer on Thursday October 131".They had
given us some suggestions to make our permit application more accurate.
They offered the following suggestions:
• Renew tier relief for Outfalls SW003,SW004, SWO05 and include SWO06 since it's in the same drainage area and
experiences the same industrial activities. SWO06 has been in tier status since the issuances of the permit in
2017. Recommended we sample from roof drains and background in the area of these outfalls to verify metals
contribution from roof drains/metal structures as well as background sampling. Recommended 1 sample per
month for 3 months.
• Remove Outfalls SWO16 and SW017.These outfalls are associated with the switchyard are consistently under
the lake level and have not been sampled during the permit term. SWO16 would be representative of SWO17 if
sampling were possible.
• Remove Outfall SWO15 as this drainage area has had no flow since early 2018.The oil storage tank has been
removed and replaced with a parking lot.There is storage for an empty spare transformer that sits in secondary
containment with a level alarm in this drainage area.
• Recommended we have an engineering firm review and certify that Outfall SWO07 is groundwater and not
stormwater runoff. Cardno did an annual non stormwater inspection in April of this year determining that the
flow from SWO07 is groundwater from a nearby spring. Inspection is attached.
Please let me know if you have any questions or concerns.Thank you

Lori,
That numbering is fine. As this outfall is not marked in any previously submitted site maps or BMPs, please provide an
updated site map with this new outfall marked as well as a narrative description and BMP summary like that provided
for the other permitted outfalls.

Outfall 003 would be a new outfall. Would SW031 be acceptable?
Thank you

Hello Lori,
I have one follow up question. Is repurposed Outfall 003 the new Outfall SW030 that was previously requested be added
to the permit? Or is Outfall 003 a separate, new outfall that needs a new number? If it needs a new number, please
assign an outfall number.

Hi Brianna,
1. The application references wanting to add a new outfall to the permit for discharge of upland flow
surrounding the ash basin. Which outfall is being referenced? We would like to repurpose the former
ash basin NPDES WW outfall 003 that discharges to an unnamed tributary to the Dan River. Latitude
36.3061, Longitude -80.0807
2. The application states outfalls SWO12 SW013, and SWO14 have been rerouted to ASTs. Where does the
flow go after it reaches the ASTs? Do the ASTs discharge, are they routed to wastewater treatment,
etc.? The ASTs go to the FGD scrubber make up systems and are not discharged.
3. Is outfall SWO10 pumped to the ash basin or ASTs? If to AST, where does it go after (see question
2). The original SW010 was abandoned during the gypsum and limestone stacker construction. All
stormwater runoff from Drainage Area 10 is collected and treated at the stormwater basin in the north
edge of the drainage area. The basin contents are pumped to the ash basin. A double 24" diameter
concrete culvert spillway for the stormwater basin is located beneath the access road. Any basin
overflow would discharge into Drainage Area 7 and then into Belews Lake. To date, no overflow events
have been recorded.
4. Could outfalls SWO11 and SWO15 be impacted by CCR due to ash hauling operations? Information from
an email dated 6/24/2016 states this. Yes
5. Could outfalls SWO01 and SW024 be impacted by CCR due to ash hauling operations? Information from
an email dated 6/24/2016 states this, but the application says stormier permit coverage is not needed.
This area consists of a guard house, water tower, some rail car staging, and a parking areas. There is no
significant material storage in this area. Outfalls SWO01 and SW024 are the same outfall.
Please let me know if you have further questions and again my apologies for the delayed
response. Thank you

After further review I have a few more questions on the Belews Creek permit.
1. The application references wanting to add a new outfall to the permit for discharge of upland flow surrounding

Good morning,
The Division of Energy, Mineral, and Land Resources (DEMLR) Stormwater Permitting Program
acknowledges receipt of your renewal application for coverage under NPDES Permit Number NCS000573.
Please continue to comply with all conditions and monitoring requirements in your current NPDES stormwater
permit. As long as you have submitted a complete renewal request package and maintain compliance with those
permit conditions, stormwater discharges from this facility are authorized by that permit until the Division
issues a renewal permit or notifies you of an alternative action.
I am working on renewing the individual stormwater permit for the Belews Creek Steam Station(NCS000573).
I need additional information in order to 1) confirm that the information I have is correct and 2) make sure the
permit adequately serves the needs of the facility. Please provide the following:
• Confirm the number of stormwater outfalls and associated coordinates;
• Confirm the status of stormwater outfalls SW001 and SW002;
• An electronic spreadsheet summarizing all of the monitoring data that has been collected since the
effective date of the current permit;
• Verification that the information in the renewal application is still complete and correct; and
• An explanation of any operational changes since the renewal application was submitted.
Enter your stormwater permit number into the Stormwater Permit Summary Report and you will see a form that
includes the address of the facility, contact information for the permit, and the regulated stormwater outfall(s)
for the facility. Please review the facility information to make sure it is correct. Information can be updated
using the links provided below, where applicable:
• Facility/Company name or ownership: Name/Ownership Change Form
• Owner Affiliation(Legally responsible person; i.e., someone with the company who is designated to
represent the company per signatory requirements or another authorized representative): Permit Contact
Update Request Form
• Delegation of Signature Authority(DOSA): Permit Contact Update Request Form
• Billing contact: Permit Contact Update Request Form
• Permit contact: Permit Contact Update Request Form

• Facility address only: Email Bethany Georgoulias
• Stormwater outfall information: Email Bethany Geor oulias
• Visit the eDMR Six Steps website and complete Steps I and 2.
• Pay outstanding permit fees: Stormwater ePayment website
Once I have the above listed information, I can continue my review. You will receive a draft permit for a 30-day
comment period. During this time we will be able to address any comments or concerns you have. During the
same 30-day period, the draft will be sent to a Regional Office staff member for review as well as out to public
notice. Once all comments and concerns are addressed, you may be issued a final permit.
Please contact me if you have any questions.

Hi Brianna,
1. The application references wanting to add a new outfall to the permit for discharge of upland flow
surrounding the ash basin. Which outfall is being referenced? We would like to repurpose the former
ash basin NPDES WW outfall 003 that discharges to an unnamed tributary to the Dan River. Latitude
36.3061, Longitude -80.0807
2. The application states outfalls SWO12 SW013, and SWO14 have been rerouted to ASTs. Where does the
flow go after it reaches the ASTs? Do the ASTs discharge, are they routed to wastewater treatment,
etc.? The ASTs go to the FGD scrubber make up systems and are not discharged.
3. Is outfall SWO10 pumped to the ash basin or ASTs? If to AST, where does it go after (see question
2). The original SWO10 was abandoned during the gypsum and limestone stacker construction. All
stormwater runoff from Drainage Area 10 is collected and treated at the stormwater basin in the north
edge of the drainage area. The basin contents are pumped to the ash basin. A double 24" diameter
concrete culvert spillway for the stormwater basin is located beneath the access road. Any basin
overflow would discharge into Drainage Area 7 and then into Belews Lake. To date, no overflow events
have been recorded.
4. Could outfalls SWO11 and SWO15 be impacted by CCR due to ash hauling operations? Information from
an email dated 6/24/2016 states this. Yes
5. Could outfalls SWO01 and SW024 be impacted by CCR due to ash hauling operations? Information from
an email dated 6/24/2016 states this, but the application says stormier permit coverage is not needed.
This area consists of a guard house, water tower, some rail car staging, and a parking areas. There is no
significant material storage in this area. Outfalls SW001 and SW024 are the same outfall.
Please let me know if you have further questions and again my apologies for the delayed
response. Thank you

Hello Lori,
After further review I have a few more questions on the Belews Creek permit.
1. The application references wanting to add a new outfall to the permit for discharge of upland flow surrounding
the ash basin. Which outfall is being referenced?
2. The application states outfalls SWO12 SW013, and SWO14 have been rerouted to ASTs. Where does the flow go
after it reaches the ASTs? Do the ASTs discharge, are they routed to wastewater treatment, etc.?
3. Is outfall SW010 pumped to the ash basin or ASTs? If to AST, where does it go after (see question 2).
4. Could outfalls SWO11 and SWO15 be impacted by CCR due to ash hauling operations? Information from an email
dated 6/24/2016 states this.

5. Could outfalls SW001 and SW024 be impacted by CCR due to ash hauling operations? Information from an email

SU-standard units <-not detected at the following level SA-semi-annual
mg/L-milligrams per liter NA-not applicable SA-QCA semi-annualor quarterly during during coal or ash transport NR-not recorded/not reported.
ug/L-micrograms per liter NE-not established Disc-discontinued
ng/L-nanograms per liter PCB-polychlorinated biphenyls ROS-representative outfall status
Compliant no shading H-Analyzed out of holding time. NFlow-no flow
Tier Requirements for Benchmark Exceedances
Tier I One exceedance of benchmark value-Inspection and evaluate causes within two weeks after receiving results and implement corrective actions within two months. Monthly sampling frequency of outfall until three(3)consecutive results are below benchmark value.
Tier II Two consecutive exceedances of benchmark value-evaluate causes within two weeks and implement corrective actions within two months. Sampling conducted monthly until three(3)consecutive results are below benchmark value.
Other Notes:
Mercury above 12 ng/L must be reported on the DMR but does not activate a Tier response

Narrative of Significant Site Changes
Outfalls SW010 and SW012 were rerouted to above ground
tanks and no longer discharge.
The outfall narrative descriptions for outfalls SW015, SW018A,
SW01813, SW019, and SW024 were updated.
SW015-The Used Oil tank was removed from the
description.
SW018A-The drainage area was updated in the description
from 3.0 to 6.1 acres based on contour data.
SW01813-The drainage area was updated in the description
from 40.2 to 42.9 acres based on contour data.
SW019-The drainage area was updated in the description from
3.0 to 34.2 acres based on contour data.
SW024-The Percent Impervious was updated from 0% to 12%
based on area measurement of the pavement and guard house.

Re: Stormwater Pollution Prevention Plan Review
Belews Creek Steam Station
CATLIN Project No. 220131
Dear Mrs. Tollie:
CATLIN Engineers and Scientists (CATLIN) is pleased to provide this letter report, outfall
analysis and recommendations for the 2021 renewal of the NPDES Stormwater Permit No.
NCS000573 (ISW Permit) for Duke Energy. CATLIN was tasked by Duke Energy to compare
the Stormwater Dischargo Permit Application to the ISW Permit, identify discrepancies, and
make recommendations for ways to address the discrepancies prior to next year's permit
renewal.
On July 9, 2020 CATLIN conducted a site visit to the Belews Creek Steam Station where the
stormwater outfalls were observed and the industrial activities within each drainage area were
verified. CATLIN then reviewed the Stormwater Discharge Permit Application, the ISW Permit,
the Stormwater Catch Basin Assessment and the maps provided showing the existing drainage
basins to determine the industrial activities exposed to stormwater associated with each outfall.
CATLIN then compared the permit requirements to the application to determine if there are
discrepancies, and if the number of outfalls can be reduced.
Table 1 contains the results of this review and lists the stormwater outfalls and
recommendations for each one with regards to renewal of the ISW Permit. It also lists any
analytical exceedances for the outfall and if it falls under any Tier Status. A summary of these
recommendations is below.
1. Pursue Representative Outfall Status (ROS) for SWO03 being representative of SWO04
2. Pursue ROS for SWO16 being representative of SWO17
3. SW011 and SWO12 can be removed from the ISW Permit in the future if they are re-
routed to above ground tanks
4. Remove SW024 removed from the ISW Permit since no industrial activity is occurring in
this basin
5. Pursue ROS for SW028 being representative of SW029

The outfall narrative descriptions for outfalls SW015, SW018A, SW018B, SW019, and SW024
were also updated in Appendix C of the ISW Permit Application with the data available to
address discrepancies as noted below.
SW015 The Used Oil tank was redlined out of the description.
SW018A The drainage area was updated in the description from 3.0 to 6.1 acres
based on contour data.
SW018B The drainage area was updated in the description from 40.2 to 42.9 acres
based on contour data.
SW019 The drainage area was updated in the description from 3.0 to 34.2 acres
based on contour data. The existing basin was much larger than 3.0
acres, so this was likely a mistake in the Permit Application.
SW024 The Percent Impervious was updated from 0% to 12% based on area
measurement of the pavement and guard house.
Several other small discrepancies in the outfall narrative descriptions were also corrected.
Outfall narrative descriptions for SW028 and SW029 were added to Appendix C.
CATLIN updated Figure 2 of the Stormwater Discharge Permit Application to include the
drainage areas for stormwater outfalls SW028 and SW029. Topographic information provided
by Duke Energy was used to delineate the drainage basins for outfalls SW028 and SW029, and
to verify and update the other drainage basins. All other drainage basins appeared accurate and
were not modified.
If we can be of any further assistance of if you have any questions please contact us at (910)
