Section 1. Facility Activities and Process:
The Weatherspoon Steam Electric Plant was a coal fired steam electric power plant(facility was retired
in 2011 and demolished in 2013) that had four(4) internal combustion turbines with a 160-megawatt net
capacity. The site contains a coal ash pond, large cooling pond, and an access road(ash hauling route).
Stormwater is routed to the cooling pond. Although electricity generation has ceased, coal ash is still
present at the site and will be disturbed and/or transported as ash pond closeout procedures are carried
out. A public hearing was held on 12/8/2016 during last permit issuance.
Per the inspection report from February 2020, ash hauling activities began in September 2017. Drainage
from the access road to SW001 is primarily sheet flow into the road shoulder and catch basins leading to
SWO03 have been covered with a metal plate, almost eliminating any flow/discharge to SW003. Per
communication dated 10/10/2022, Duke Energy estimated onsite ash removal activities would be
completed in three (3) years.
Per the November 2022 inspection report, analytical monitoring was only conducted at outfall SW-2 as
outfall SW-1 only sheet flows and the drains leading to outfall SW-3 have been covered with metal
plates. Also, approximately 25 trucks enter and exit the facility twice per day, five days per week, with
an estimate that ash hauling should be completed in approximately three more years.
Outfall SW001:
Drainage area includes runoff from the access road(ash hauling route). A culvert connects an offsite
pond adjacent to a used automobile parts business to this area.
Outfall SWO02:
Drainage area includes runoff from the access road(ash hauling route), ditches along an abandoned
railroad, an admin building and parking lot, and a vegetative area adjacent to the power plant.

Outfall SW003:
Drainage area includes runoff from the access road(ash hauling route) and a picnic area adjacent to the
power plant.
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."
Section 2. Monitoring Information and Compliance History:
• December 2017 to August 2022, benchmarks exceeded for(only SW002 results submitted):
o SW002: TSS 2x, Copper 2x, Zinc Ix
• Per letter dated Q1 2019, SW002 was in Tier I status for TSS
Representative outfall status was previously granted(see DEQ letter dated 9/4/2009) for outfall SW002
to represent outfalls SW001, SW002, and SW003 but appears to have been revoked with the last permit
renewal.
Per information provided by the permittee 10/18/2022, there is no monitoring data for SW001 or SW003
as neither outfall has actual discharge from the permitted outfall site (SW001 only has sheet flow and
SW003 has metal plates welded on the inlets).
TMDL:
A TMDL exists for the entirety of the Lumber River Basin for mercury (Statewide Mercury TMDL
overrides this).
Threatened/Endangered Species:
In the vicinity of the discharge outfalls is the Carolina Bogmint(Macbridea caroliniana;NC status: E).
Additionally, in the adjacent and nearby vicinity there are the Phantom Darner(Triacanthagyna trifida;
NC status: SR), Coppery Emerald(Somatochlora georgiana;NC status: SR), Comfortroot(Hibiscus
aculeatus; NC status: T), American Alligator(Alligator mississippiensis;NC status: T; Federal status:
Page 2 of 8

T(S/A), Ironclad Shiner(Notropis chalybaeus;NC status: SR), Florida Yellow-eyed-grass (Xyris
floridana; NC status: SC-V), Shining Clubtail (Stylurus ivae;NC status: SR), and Sebastian-bush
(Ditrysinia fruticose;NC status: SR-P).
Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities (coal-fired
electric generation, plant decommissioning, and ash removal) and data was submitted for December
2017 to August 2022. Quantitative sampling included pH, TSS, non-polar O&G, boron, zinc, antimony,
arsenic,beryllium, cadmium, chromium, copper, lead, nickel, selenium, silver, thallium, and mercury.
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 Weatherspoon Steam Electric Plant site.
Per the 2016 permit renewal application, Duke Energy indicated magnesium and molybdenum as
potentially being in the coal ash. These pollutants are not being included in the current permit as they do
not have surface water quality standards and do not provide any additional information on the presence
of coal ash in the outfall.

Weatherspoon's wastewater NDPES permit NC0005363 requires fish tissue monitoring for arsenic (As),
selenium(Se), and mercury(Hg)near the ash pond discharge each year. The proposed stormwater
permit requires the permittee to submit a copy of monitoring results to the DEMLR Stormwater Program
(Central Office) within 30 days of receiving results and indicate the location of sampling in relation to
stormwater discharge outfalls. DEMLR is requiring the fish tissue analysis results be submitted
separately to ensure Stormwater Program staff who are not in the Division of Water Resources receive
results and have an opportunity for review.
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
Page 4 of 8

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.
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:
Parameter Benchmark Basis
Total Suspended 100 mg/L National Urban Runoff Program(NURP) Study, 1983
Solids TSS
H 6 s.u. —9 s.u. NC Water Quality Standard(Range)

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 1631E, 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
Page 6 of 8

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:
• Quarterly monitoring required for all parameters (qualitative and quantitative)
• "No discharge" clarifications made
• eDMR requirement added
• Boilerplate language moved into body of the permit; boilerplate no longer attached
• Monitoring for total hardness added for all outfalls as monitoring for hardness dependent metals
is required
• Benchmarks updated for parameters per guidance from DWR Standards group on stormwater
benchmarks
Section 5. Changes from draft to final:
• Facility site map updated
• Feasibility study requirement removed due to programmatic change
Section 6. Discussions with the Facility and Regional Office:
• Initial contact with facility: 9/21/2022
• Initial contact with Regional Office: 9/21/2022
• Draft sent to CO peer review: 11/9/2022
• Draft sent to Regional Office: 2/2/2023
• Final permit sent for supervisor signature: 3/10/2023

Permit: NCS000589 Owner-Facility:Duke Energy Progress LLC
Inspection Date: 11/02/2022 Inspection Type:Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
Inspection conducted as part of the individual stormwater permit renewal process.Met with Kent Tyndall, Lead EHS
Professional, and Ricky Stroupe, CCP Environmental Field Support. Application for permit renewal has been submitted as
required. Based on review of the facility's monitoring records, facility was triggered into monthly monitoring of all parameters
under the current permit's Tier One response actions due to an exceedance of the benchmark value for TSS at outfall SW-2
in December 2018. Additionally, there was an exceedance of the benchmark value for Zinc in December 2019, TSS and
Copper in September 2020, and Copper in April 2022. Monthly monitoring has been conducted and recorded continuously
since December 2018 as there has not been three consecutive monitoring events with all results below benchmarks. For
several months in 2019 as well as late 2020 into most of 2021, 'No Flow'was recorded. It should be noted that there have
been no consecutive exceedances of any parameter. Analytical monitoring has only been conducted at outfall SW-2 as
outfall SW-1 has been determined to have only sheet flow and the drains leading to outfall SW-3 have been covered with
metal plates. In an attempt to determine what might be causing the sporadic exceedances,facility staff have evaluated the
weather conditions that occurred during the respective sampling events (large storms/hurricanes)and even tested the fines
associated with the available gravel that was purchased to place on parking and roadways after large storm events. Results
of the gravel fines testing, which were provided for review during the inspection, show extremely elevated levels of all
parameters; not just TSS, Zinc and Copper. Facility's SWPPP contains all necessary components and is reviewed/updated
on an annual basis. Documentation related to facility inspections, employee training, evaluations of the stormwater outfalls
for the presence of any non-stormwater discharges, listing of significant spills (none),effectiveness of BMPs, and
comparison of monitoring data to the benchmark values was also provided for review.
Regarding the facility's ash hauling activities; approximately 25 trucks enter and exit the facility twice per day, five days per
week. Facility staff estimate that ash hauling should be completed in approximately three more years.
After the records review, observations were made of the ASTs and other containers with secondary containment. Trucks
hauling ash along the travel route as well as the catch basins leading to outfall SW-2 were also observed.

Brianna,
Attached is a copy of the inspection report for Weatherspoon (NCS000589). I will also upload a copy to the FRO folder in
Laserfiche.
Also attached are a couple of documents provided by facility staff during the inspection. One is a spreadsheet of
monitoring data for their current permit period, including data on testing of gravel fines. The other is a power point style
summary of their response actions and investigations regarding occasional benchmark value exceedances.
Please note the following additional comments/recommendations:
• facility staff have requested tier relief from monthly monitoring;they feel that the occasional benchmark
exceedances are due to gravel fines and not ash
• 1 informed facility staff during the inspection that I would not grant tier relief considering that there have not
been exceedances of any of the other parameters,which based on their results of testing gravel fines should be
the case
• I'm not certain why their permit contains monthly monitoring under Tier One (a single exceedance triggers
monthly monitoring)when all of our other permits (general and individual) have it under Tier Two after
consecutive exceedances; was this done specifically for the power plants with coal ash?; unless there is a
specific reason for these facilities to have the monthly monitoring condition under Tier One, I recommend
moving monthly monitoring to the Tier Two response actions to be consistent with all other permits
If you need any additional information or we need to discuss my recommendation above in further detail, please contact
me.

Permit: NCS000589 Owner-Facility:Duke Energy Progress LLC
Inspection Date: 11/02/2022 Inspection Type:Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
Inspection conducted as part of the individual stormwater permit renewal process. Met with Kent Tyndall, Lead EHS
Professional, and Ricky Stroupe, CCP Environmental Field Support.Application for permit renewal has been submitted as
required. Based on review of the facility's monitoring records, facility was triggered into monthly monitoring of all parameters
under the current permit's Tier One response actions due to an exceedance of the benchmark value for TSS at outfall SW-2
in December 2018. Additionally,there was an exceedance of the benchmark value for Zinc in December 2019, TSS and
Copper in September 2020,and Copper in April 2022. Monthly monitoring has been conducted and recorded continuously
since December 2018 as there has not been three consecutive monitoring events with all results below benchmarks. For
several months in 2019 as well as late 2020 into most of 2021, 'No Flow'was recorded. It should be noted that there have
been no consecutive exceedances of any parameter. Analytical monitoring has only been conducted at outfall SW-2 as
outfall SW-1 has been determined to have only sheet flow and the drains leading to outfall SW-3 have been covered with
metal plates. In an attempt to determine what might be causing the sporadic exceedances,facility staff have evaluated the
weather conditions that occurred during the respective sampling events (large storms/hurricanes)and even tested the fines
associated with the available gravel that was purchased to place on parking and roadways after large storm events. Results
of the gravel fines testing,which were provided for review during the inspection, show extremely elevated levels of all
parameters; not just TSS, Zinc and Copper. Facility's SWPPP contains all necessary components and is reviewed/updated
on an annual basis. Documentation related to facility inspections, employee training, evaluations of the stormwater outfalls
for the presence of any non-stormwater discharges, listing of significant spills (none),effectiveness of BMPs, and
comparison of monitoring data to the benchmark values was also provided for review.
Regarding the facility's ash hauling activities; approximately 25 trucks enter and exit the facility twice per day, five days per
week. Facility staff estimate that ash hauling should be completed in approximately three more years.
After the records review, observations were made of the ASTs and other containers with secondary containment Trucks
hauling ash along the travel route as well as the catch basins leading to outfall SW-2 were also observed.

Thanks, Mike. In regards to Tier status, I didn't see anything in the permit file during my review as to why Tier 1 would
be different than the standard.The new draft permit follows the same Tiered guidance as all other individual permits.

Brianna,
Attached is a copy of the inspection report for Weatherspoon (NCS000589). I will also upload a copy to the FRO folder in
Laserfiche.
Also attached are a couple of documents provided by facility staff during the inspection. One is a spreadsheet of
monitoring data for their current permit period, including data on testing of gravel fines.The other is a power point style
summary of their response actions and investigations regarding occasional benchmark value exceedances.
Please note the following additional comments/recommendations:
• facility staff have requested tier relief from monthly monitoring;they feel that the occasional benchmark
exceedances are due to gravel fines and not ash
• 1 informed facility staff during the inspection that I would not grant tier relief considering that there have not
been exceedances of any of the other parameters,which based on their results of testing gravel fines should be
the case
• I'm not certain why their permit contains monthly monitoring under Tier One (a single exceedance triggers
monthly monitoring)when all of our other permits (general and individual) have it under Tier Two after
consecutive exceedances; was this done specifically for the power plants with coal ash?; unless there is a
1

specific reason for these facilities to have the monthly monitoring condition under Tier One, I recommend
moving monthly monitoring to the Tier Two response actions to be consistent with all other permits
If you need any additional information or we need to discuss my recommendation above in further detail, please contact
me.

I have started reviewing the renewal application for the Weatherspoon Steam Plant (NCS000589). Please let me know if
there are any concerns that should be addressed during this renewal. It looks like an inspection was last done in
February 2020, but please perform another inspection to confirm site conditions.

CAUTION: External email. Do not click links or open attachments unless you verify.Send all suspicious email as an attachment to

Good morning Brianna,
There is no monitoring data for SWO01 or SWO03 due to the following:
• SWO01: No sample collected since SW1 only has 'sheet flow' (no actual discharge from the permitted site
outfall).
• SWO03: No sample collected since SW3 has metal plates welded on the inlets (no actual discharge from the
permitted site outfall).
These notes are included on the eDMR and the qualitative monitoring reports.
I hope this answers your question. Please contact either Elizabeth or myself if you have additional questions.Thank you!

Hello Elizabeth,
I have one follow up question—the monitoring data supplied only includes outfall SW002. Is there any monitoring data
for outfalls SWO01 and SWO03?
