1.1 SW004
• On June 19, 2023, monthly stormwater samples were collected and analyzed in accordance
with NCS000020. Analytical results for SW004 (ROS)were received by Duke Energy on June
29, 2023. Upon review of the results, it was observed that the benchmark for Zinc and Copper
were exceeded. The benchmark for Copper is 10 pg/L and the analytical result was 22 pg/L.
The benchmark for Zinc is 126 pg/L and the analytical result was 408 pg/L. This is the 4th
benchmark exceedance for Zinc within a 5 year period.SW004 entered into Tier III status for
Zinc on June 29th, 2023. Most recent benchmark exceedances for SW004 are included below.

2 Inspection Report
McGuire Station Sciences Management, Site Services Management, and Nuclear Environmental
Field Support conducted a thorough inspection of SWO04 drainage basins on June 29th, 2023.
This Inspection Report is included in Appendix A.
3 Review
3.1 SW004
The drainage area for SWO04 is comprised of a paved industrial asphalt surface which includes multiple
buildings, along with storage of sea-land containers and industrial equipment. Flow is also received from
a graveled lay down storage yard which includes a discarded material storage building, paint warehouse,
and facilities maintenance shop. Outfall 004 has Representative outfall status because the State has
deemed it substantially identical to the adjacent drains in the same area.
The paved asphalt surface includes 3 metal buildings: Mausoleum, Crane Storage, and Transmissions
Storage. There are also multiple sea land containers stored within this area. When not being used during
outage times, sea land containers are stored in the asphalt lay down area. The crane storage,
transmission storage, and a small extension of the mausoleum building contains a metal roof. The
transmission storage building is the only building without downspouts.
At times, pieces of heavy equipment such as JLG lifts, cranes, forklifts, or small excavators are stored in
the asphalt laydown area. Equipment and metal pieces are also stored here as well when not being
utilized in the plant.
The entire area is surrounded by a fence, which has been replaced. The details of this project, along
with all other BMP's and upgrades to help alleviate exceedances are discussed in the following
appendices.
Tier III Action Plan —July 2023

4 Action Plan and Associated Costs
4.1 SW004
The results of management walkdowns identified zinc and copper contributing sources. Some sources
identified were removed upon initial walkdown. Potential sources such as degraded galvanized fencing and
any building in the laydown area were tested for heavy metals. A piping inspection was performed using a
remote camera to investigate the piping as a potential source of heavy metals. HalenHardy was contracted to
develop filtration for the storm drain collection areas to remove heavy metals.
A HalenHardy 4 stage filtration system was purchased to surround the two storm drains that feed SW004. A
filtration system was also installed and is currently in use. Based on heavy metals results from the galvanized
fencing analysis, the entire fencing around this storm drain and asphalt laydown area has been removed and a
new coated fence has been installed. The storm drain pipe was determined to be a galvanized pipe.
Bionomics was contracted to install a junction box and to sleeve the 140 ft of piping with a special sleeve to
prevent leaching of heavy metals into storm drain run-off. The asphalt was swept multiple times to remove any
potential heavy metals. Additional management walkdowns identified other potential heavy metals sources
with materials that are being stored in the area. Some of the items can be relocated in addition to continued
removal of sealand containers.
Storm Drain Lining Project Cost:
$38,500-Junction box for tie into storm drain
$2,500- Robot to view galvanized storm drain piping
$3,000- Labor and oversight for storm drain piping sleeve
$125,000-Cost of the actual storm drain piping sleeve and installation
_$168,500 total for storm drain lining
Fence Removal and New Coated Fence Cost:
$177,205-Cost to remove old fencing and to install new fencing.
PIG Stormwater Heavy Metal Filter Sock Cost:
$1,229-Cost for the 1 st set of filters ordered from PIG
HalenHardy 4 Stage Filtration System:
$9,834-Cost for filtration system plus shipping
Total Cost Spent To Reduce Heavy Metals In SW004:
$356,768
Duke Energy has implemented several proactive steps to address the exceedance of benchmarks as
noted above and in Appendix A(Inspection Report/Site Pictures)and B (Best Management Practices).
Duke Energy will continue to assess the effectiveness of these improvements and will implement other
appropriate best management practices and/or physical improvements to assure compliance with
NPDES NCS000020 and the associated benchmarks.
4.2 Response Action Timeline for SW004 Benchmark Exceedances
12/14/2022: During a rain event, MNS Chemistry performed the permit required sampling on
Stormwater Outfall SW004, SW006, and SW008.Visual observations at the time of
sampling showed no adverse color, foam, or odors. Flow volume was 6 gpm from SW004.
12/29/2022: Sample results received on 12/29/22 showed a Benchmark exceedance of Zinc on
SW004. Zinc was 165 ppb against the benchmark value in our Industrial Stormwater
permit of 126 ppb. With those results, MNS entered Tier Two response actions according
to the ISW Permit requirements when 2 consecutive benchmark exceedances occur.
Tier III Action Plan —July 2023

Duke Energy
01/10/2023: The NC DEQ DEMLR Mooresville Regional Office was notified in writing via Certified Mail.
01/09/2023: Management meeting as required by the Tier Two guidance was held to discuss options
to implement in order to meet the benchmark value for Zinc. Those attending the meeting
were Greg Beaver, John Ballard, Don Safrit, Randy Hawkins, and members of the
company Halen Hardy. Actions already taken were discussed which included general
housekeeping of the area, sweeping the entire asphalt area, removal of equipment that
did not need to be in the area, and the installation of metal removing filter socks. Halen
Hardy will provide guidance on a 3 tiered more robust filtering of the drainage area which
will include installing sediment filter socks, carbon filter socks, and a polymer filter media.
Once the BMP recommendation is received from Halen Hardy, the filters will be
purchased and installed. Test sampling will be performed which will include sampling
downspouts from building roof drains and sampling downstream of the filter media once
installed.
2/15/2023: Filters were purchased and installed on 02/15/2023. A four-tiered filtering system
consisting of Oil and Sediment filter dikes, carbon filter dikes, heavy metal filter dikes,and
heavy metal filter sponge material was installed at both of the Stormwater filter drains that
feed SW004. Heavy Metal Test samples were pulled in 01/17/23 from existing metal
building downspouts and from the galvanized fencing surrounding the asphalt area that
drains to SW004. The galvanized fencing material resulted in 786 ppb Zinc. The Grove
Crane Building resulted in 1270 ppb Zinc. The Transmission Storage Building resulted in
2960 ppb Zinc. Site Management was briefed with those sample results and they are
evaluating options to eliminate those known Zinc Sources.
2/25/2023: During a rain event, MNS Chemistry performed the Permit Required Tier II Response
actions of monthly sampling of Outfall 004 after the new heavy metal filters were installed
on the 2 yard drains that feed this outfall.Visual observations at time of sampling
showed no adverse color, foam, or odors. Flow volume was 5 gpm from SW004.
3/9/2023: Sample results received on 3/9/2023 showed a Benchmark exceedance of Zinc on
SW004. Zinc was 157 ppb against the benchmark value in our industrial Stormwater
permit of 126 ppb. This is the 3rd consecutive benchmark exceedance of Zinc on Outfall
SW004. MNS remains in Tier 11 Response action status as a result.
3/15/2023: Management meeting/walkdown with Site Services Manager Ken Barrow, John Ballard
and Summit(Vendor) met onsite with a robotic camera to scope the discharge pipe
between the yard filter drains and the Discharge of SW004. Discovered that the discharge
pipe has a 140 ft section that is not corrugated black plastic as we believed but is actually
old metal piping. This section of piping is believed to be contributing Zinc back into the
discharge flow downstream of the installed filtration from Halen Hardy. Discussed
appropriate options and decided that the best option is to install an access manway and
sleeve the existing discharge pipe to prevent the continued leaching of Zinc into SW004.
Installation/repair expected to occur by 3/31/23.
3/17/2023: During a rain event, MNS Chemistry performed the Permit Required Tier II Response
actions of monthly sampling of Outfall 004. Visual observations at the time of sampling
showed no adverse color, foam, or odors. Flow volume was 50 gpm from SW004.
3/2112023: Junction box with access manway was installed at the junction of metal to plastic pipe on
the SWO04 discharge line.
3/30/2023: Sample results received on 03/30/2023 showed all sample parameters were below the
benchmark values for the month of March 2023. Zinc was 113 ppb against the benchmark
value of 126 ppb: MNS remains in Tier 11 Response Actions as this is the first month with
Zinc results under the Benchmark Value.

4/30/2023: SWO04 remains in Tier li Response Actions which requires monthly sampling. There was
no discharge from this outfall during any measurable storm event that occurred during the
facility's normal operating hours and began at least 72 hours after the previous
measurable storm event for the April 2023 monitoring period. "No Discharge"was
recorded and submitted in the April eDMR.
5/1/2023: Contractor was on site and deployed a robotic camera into the stormwater drain line to
assess the condition of the 140 ft section of galvanized pipe and take measurements to
fabricate the sleeve material. Actual pipe sleeving expected to occur in 2 to 4 weeks.
5/22/2023: Contractor Gaston Fence company began removing the old, galvanized fencing
surrounding the drainage area that feeds SW004. New rubber coated fencing will be
installed after the old fence is removed.
5/31/2023: SWO04 remains in Tier II Response Actions which requires monthly sampling. There was
no discharge from this outfall during any measurable storm event that occurred during the
facility's normal operating hours and began at least 72 hours after the previous
measurable storm event for the May 2023 monitoring period. "No Discharge"was
recorded and submitted in the May eDMR.
6/12/2023: Contractor Bionomics on site and installed the sleeve on the 140 ft section of galvanized
pipe upstream of SWO04 and the stormwater collection drain pit. All work on this section
of stormwater piping is now complete.
6/19/2023: During a rain event; MNS Chemistry performed the Permit Required Tier II Response
actions of monthly sampling of Outfall 004. Visual observations at the time of discharge
sampling showed a light reddish tinted cloudy color from fencing removal and installation
activities, a slight glue smell from the recent sleeving of the galvanized pipe, and no foam.
Flow volume was 100 gpm from SW004.
6/29/2023 Sample Results received on 6/29/2023 showed Benchmark exceedances of Zinc and Copper
on Outfall SW004. Zinc was 408 ppb against the Benchmark value of 126 ppb. Copper was
22 ppb against the Benchmark value of 10 ppb. Outfall SWO04 is now elevated to Tier III
Response Actions as a result of the 4th Zinc Benchmark Exceedance within a 5 year period.
6/29/2023 Management meeting/walkdown performed as required with Site Services Manager Ken
Barrow, Station Sciences Manager Travis Rollins, Site Environmental Professionals Greg
Beaver and John Ballard, Site Services Rob Dlugolinski, and Transmission Matt Harris. It was
noted during the walkdown that the removal process of the old, galvanized fencing and posts
likely contributed to the Zinc and Copper Benchmark exceedances during this sampling event.
Further cleanup and sweeping of the area will be performed following the completed
installation of the rubber coated replacement fence, which is still ongoing. Continue to remove
unneeded Sealand containers,transformer parts, and other miscellaneous metal parts that are
currently stored in this area.
7/5/2023 The NC DEQ DEMLR Mooresville Regional Office was notified in writing via Certified Mail of
the Zinc and Copper Benchmark Exceedances from the 6/19/2023 rain event sampling.
5 Monitoring Plan
5.1 SWO04
Following determination of zinc inputs and mitigation efforts, stormwater samples will be collected
monthly as required under Tier III status to monitor impacts (if any)to stormwater discharge.

Tier III Action Plan —July 2023

1 Best Management Practices Summary
A number of best management practices (BMPs) are currently in place at the station. These BMPs were
instituted over a number of years as a result of various regulatory drivers and good housekeeping
objectives. While a chosen practice provides some level of pollution prevention as it relates to the
management of stormwater discharges under this permit, the historic rationale behind implementing such
a practice is comprehensive of a number of contributing factors. The ongoing implementation of these
practices are part of the Stormwater Pollution Prevention Plan (SWPPP). The detailed listing of these
BMPs for the drainage area is provided in the outfall descriptions (Appendix B)where information
regarding the industrial activities and significant sources of pollutants are also compiled. The compiled
information in the appendix captures an ongoing assessment process for BMP selection and
implementation.
The Site Environmental Coordinator shall rely on the improvement, installation and implementation of
BMPs to address data collected through monitoring of stormwater discharges. The Site Environmental
Coordinator may also rely on other sources of information to implement other appropriate BMPs not listed
in Table 2. This list of BMPs shall be reviewed and updated annually as new practices are incorporated in
the plan or warranted as a result of exceedances of analytical monitoring benchmarks.
1.1 Fence Management
Rainfall may be contaminated as it is exposed to the degraded galvanized fencing if not managed
properly. Fencing is a likely source of heavy metal contamination and thus the fencing surrounding
the entire asphalt laydown area and storm drains has been removed. New coated fencing is in the
process of being installed so that no galvanized metal is exposed to rainfall. As seen in the photos
in Appendix B, part of the fencing is installed.
1.2 Galvanized Storm Water Piping
Upon inspection of the storm water piping, it was discovered that 140 ft of piping that leads directly from
the storm drain to SW004 discharge junction box was corrugated galvanized pipe. It is believed that the
galvanized piping is a direct contributor to the heavy metals at SW004 and needed to be replaced or
sleeved. Contractor Bionomics sleeved the galvanized pipe with a special coating. A junction box was
initially installed to connect the last 40 foot of piping to the end of the outfall. At this point, all of the
piping is either coated or plastic.
1.3 Storm Drain 4 Stage Filtration System
Contractor HalenHardy that specializes in storm drain filtration contacted to devise a plan to filter out any
heavy metals of SW004 prior to storm water entering the drain. They developed a 4 tier filtering system
consisting of Oil and Sediment filter dikes, carbon filter dikes, heavy metal filter dikes, and proprietary
heavy metal filter sponge media. Dimensions of the storm drain pad and storm drain were provided to
HalenHardy so that exact size dikes could be installed in a specific manner for the most effective
method of filtering the water. Pictures of the drains are listed in the appendix B.
1.4 Material Storage Areas
There are sealand containers, multiple heat exchanger parts, construction equipment, cranes, JLG lifts,
forklifts, transformer material, security BRE's, miscellaneous pieces of metal, etc. in the asphalt laydown
area. Exposure of the materials to rainfall and stormwater run-off has the potential to contaminate
stormwater. In the meantime, best efforts are being made to reduce the number of these items in the
area.

Project: J23050182 McGuire SW
Pace Project No.: 92673536
DEFINITIONS
DF-Dilution Factor,if reported,represents the factor applied to the reported data due to dilution of the sample aliquot.
ND-Not Detected at or above adjusted reporting limit.
TNTC-Too Numerous To Count
J-Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL-Practical Quantitation Limit.
RL-Reporting Limit-The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S-Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270.The result for each analyte is
a combined concentration.
Consistent with EPA guidelines,unrounded data are displayed and have been used to calculate%recovery and RPD values.
LCS(D)-Laboratory Control Sample(Duplicate)
MS(D)-Matrix Spike(Duplicate)
DUP-Sample Duplicate
RPD-Relative Percent Difference
NC-Not Calculable.
SG-Silica Gel-Clean-Up
U-Indicates the compound was analyzed for,but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting.Therefore,calculated parameters that are typically reported as
"Total"may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited.Contact your Pace PM for the current list of accredited analytes.
