Duke Energy Progress, LLC (Duke Energy) - Shearon Harris Nuclear Power Plant NPDES Permit No. NC0039586, Wake County Clarifications to Mixing Zone Modeling & Analysis

Dear Mr. Smith:

The 2016 NPDES Permit for Duke Energy's Shearon Harris Nuclear Power Plant (HNP) included new effluent limits for copper and zinc at Outfall 006, which discharges into Harris Lake. This permit, effective September 1, 2016, required compliance with these new limits by September 30, 2021. In accordance with the strategy outlined in the Corrective Action Plan (CAP), submitted to NC DEQ's Division of Water Resources (DWR) in September 2017, Duke Energy has expanded sampling and effluent characterization, employed water chemistry management strategies, and completed specialized testing and site-specific engineering studies.

In August 2020, as part of these compliance activities, Duke Energy submitted the results of a Mixing Zone Study (Study), completed at the request ofDWR. The Study used EPA guidance and national best practices to complete hydrodynamic modeling of mixing zones, evaluate acute and chronic mixing zone boundaries, and calculate dilution effects. In November, Duke Energy and DWR held a video conference call to address DWR questions about the Study.

At this meeting, DWR raised two questions regarding the CORMIX hydrodynamic model and recommended additional modeling runs to validate results. Although originally requesting additional review time, DWR confirmed by email on December 11 th, that their review was complete, and they had no additional questions or concerns. After performing the requested additional modeling runs, responses to DWR's two inquiries were detailed in the enclosed Technical Memorandum (TM).

Duke Energy trusts DWR is satisfied with the responses and supplemental modeling provided in the TM. Duke Energy requests the Study be approved, and the conclusions implemented to remove the copper and zinc limits from Outfall 006 within NPDES Permit No. NC0039586.

Duke Energy respectfully requests the removal of copper & zinc limits associated with Part I (A)(6) Effluent Limitations and Monitoring Requirements (Outfall 006) and the compliance language and date of September 30, 2021 as addressed in Part I (A)(9) Schedule of Compliance (Outfall 006). A check for $1,030 made payable to NC DEQ DWR for the major permit modification processing fee is enclosed. Duke Energy remains committed to continued compliance at HNP and requests DWR issue an appropriate permit revision as soon as practicable but prior to the current NPDES permit expiration date of August 31, 2021.

Brad Paulson - Jacobs Executive Summary In July 2019, as a response to Duke Energy's submittal of a Water Effect Ratio Study, the North Carolina Division of Water Resources (DWR) requested that a dye dispersion study or dilution modeling be completed to augment the WER Study results and further inform the development of permit limits for Total Recoverable Copper at Outfall 006 of the Shearon Harris Nuclear Plant (HNP) dischargi ng into Harris Lake. Accordingly, Duke Energy conducted a mixing zone study following U.S. Environm ental Protection Agency (EPA) guidance and using the Cornell Mixing Zone Expert System (CORMIX

).

The results of that study, submitted in August 2020, indicated significant dilution effects occur at Outfall 006. Within the model, the least favorable of eight seasonal cases predicted a dilution factor of 15.3 (or 6.5% lnstream Water Concentration [IWC]) at the acute mixing zone boundary, equivalent to an allowable daily maximum of 166.1 µg/L for Total Recoverable Copper.

After reviewing the Mixing Zone Study, DWR had two questions regarding the CORMIX model:

1. Is the modeling algorithm for a "Heated Discharge" different than what is used for the "Conservative Pollutant" option?

2. What is the sensitivity of the model to variations in Reservoir levels?

Responses to these two inquiries are detailed in this Technical Memorandum (TM) and were confirmed with additional CORMIX model runs. In both cases, the model results reaffirmed the conclusion that, when dilution effects are considered, the maximum predicted copper concentration at Outfall 006 (calculated by DWR Reasonable Potential Analysis spreadsheets) is less than half of the allowable limit.

Jacobs Clarifications to Mixing Zone Modeling & Analysis

1. Introduction Duke Energy conducted a mixing zone study evaluating the dilution provided for the discharge from Outfall 006 from Shearon Harris Nuclear Plant (HNP) into Shearon Harris Reservoir under National Pollutant Discharge Elimination System (NPDES) Permit No. NC0039586, effective September 1, 2016.

Prior to initiating modeling, a plan for the Mixing Zone Study was submitted to DWR on November 15, 2019, which included proposing using CORMIX for dilution modeling. Email approval of the study plan was received from DWR with the following recommendations:

• Ambient data collected since 2017 needs to include seasonal measurements of velocity, temperature, and density at the site of discharge and anticipated plume; and

• The thermocline should be sufficiently characterized and modeled as a boundary condition where appropriate.

Both ambient current and seasonal density gradients were addressed and incorporated into the modeling approach. CORMIX modeling results and mixing zone analysis were summarized in the Mixing Zone Study (Study), dated August 14, 2020, which was submitted concurrently with the Year 4 Activities Report for the Corrective Action Plan, dated August 19, 2020.

Duke Energy requested the opportunity to discuss both the Study and the conclusions summarized in the Year 4 Activities Report with DWR and to address any questions or concerns. A video conference call was held on November 2, 2020, with Duke Energy, DWR, and Jacobs personnel. Meeting minutes for this video conference are included as Attachment A.

While DWR expressed confidence in the overall approach and information they had reviewed, two specific questions were raised by David Hill regarding the CORMIX model:

1. Is the modeling algorithm for a "Heated Discharge" different than what is used for the "Conservative Pollutant" option, and how are the predicted dilution factors and plume dimensions affected?

2. What is sensitivity of the model results to variations in key input parameters such as reservoir levels?

Responses to these two inquiries are detailed in the following sections and were evaluated with additional CORMIX model runs. A representative sample of the validating runs was selected for each section and output data included as Attachment B and Attachment C, respectively.

2. Temperature Dispersion Versus Conservative Constituent Dilution In accordance with the-approved study plan, the-G0RMIX-hydrodynamie-modeling-system-( G0RMI~1--- - - - - -

module) was used to calculate the dilution and associated plume dimensions for a range of effluent and ambient conditions. CORMIX is an EPA-supported empirical modeling system based on experimentally derived curve-fit equations that predict dilution and verify the accuracy of theoretical models. The model emphasizes prediction of the near-field geometry and dilution, although it also predicts the behavior of the discharge plume beyond initial mixing (e.g., in the far-field).

2.1 CORMIX Pollutant Types The inputs for 'pollutant type' in CORMIX allow for five types of pollutant discharges (described in Section 4.3.1 of the CORM IX User Manual [Daneker and Jirka, 2007)). Specifically, these pollutant types are as follows:

1. Conservative Pollutant - no decay or growth processes occur; pollutant of concern can be in any unit of concentration (e.g., µg/L, °C, ppm, or%)

2. Non-conservative Pollutant - first-order decay or growth processes occur; pollutant of concern can be in any unit of concentration (e.g., µg/L, °C, ppm, or%)

Shearon Harris Nuclear Plant - Permit NC#0039586 Clarifications to Mixing Zone Modeling & Analysis Jacobs

3. Heated Discharge - capable of modeling heat loss to the atmosphere using a specified surface heat exchange coefficient, which is a function of wind velocity and ambient receiving water temperature; discharge dilution/concentration is shown in terms of thermal properties or "heat concentration" (shown as °C)

4. Brine Discharge - discharge density greater than ambient density (e.g., desalination by-product); may also include a pollutant concentration of interest (conservative/non-conservative/heated discharge)

5. Sediment Discharge - discharge density greater than ambient density with settling particles (e.g., discharge with suspended sediments); may also include a pollutant concentration of interest (conservative/non-conservative)

The two pollutant types directly applicable to effluent at Outfall 006 are 1) 'conservative pollutant' (i.e.,

effluent properties considered in the Study, such as zinc and copper concentrations or hardness - do not experience decay in freshwater) and 3) 'heated discharge'.

2.2 Selection of a "Pollutant Type" for HNP's Outfall 006 In modeling Outfall 006 (or any freshwater discharge) in CORMIX, thermal data- both effluent and ambient - is essential to predict discharge behavior, as temperature is equivalent to relative density, which governs hydrodynamics. Whether using pollutant TYPE 1 or TYPE 3 in the CORMIX model, the same thermal input is required, and all versions of Outfall 006 have a discharge which is "heated" (warmer than ambient temperatures).

The only meaningful distinction between the "conservative pollutant" and "heated discharge" options is that the latter has the added functionality of modeling atmospheric heat loss, if applicable, using a surface heat exchange coefficient (based on wind velocity and ambient water temperatures). This functionality is more useful when looking at far-field effects (i.e., when the plume behavior is impacted by ambient conditions more than initial discharge velocity) or where a shallow discharge allows for significant plume-surface interaction with a high heat exchange coefficient.

For purposes of the Study, only near-field effects were evaluated, and surface heat losses were not expected to be impactful at Outfall 006, considering its depth and the presence of a thermocline in Summer and Fall. However, unless a non-conservative property is being evaluated, Jacobs typically defaults to the 'Heated Discharge' type when generating new model scenarios. In general, this is a more robust option in the event that surface heat-losses do impact an analysis.

2.3 Concurrence from CORMIX Software Developer As mentioned above, in the absence of atmospheric heat losses, both the "conservative pollutant" and "heated discharge" options are essentially identical in their predictive algorithms. In theory, if a model is run with a surface heat exchange coefficient of zero (or near zero), or if a predicted discharge plume does not come in contact with the surface, CORMIX results - including centerline dilution and plume geometry

- from either pollutant type should be fully identical.

To confirm our understanding of the CORMIX model algorithms and Pollutant Type functionality, Jacobs reached out to the software developer (MiXZon, Inc.) on November 9, 2020. Senior Software Engineer Adi S. Ramachandran explained, "assuming all CORMIX model input parameters are the same, CORMIX should predict the same flow class [and thereby provide the same predictions] when specified as using the 'Conservative Pollutant' vs 'Heated Discharge' pollutant options." He further noted that - due to the ability of the "Heated Discharge" option to model atmospheric heat loss - results CAN vary in cases where there is a "loss of buoyancy in a positively buoyant surfacing plume due to ... surface heat exchange, mainly in the buoyant spreading regions of the prediction."

2.4 Validation of Study Model Results Using the "Conservative Pollutant" Type To further validate the assertion that in the absence of atmospheric heat losses "conservative pollutant" and "heated discharge" produce identical results, CORMIX cases from the Study were rerun using the TYPE 1 "Conservative Pollutant" option using copper concentration as the material of interest, rather than temperature. For the Summer/Fall cases (Cases 3a, 3b, 4a, and 4a), where the thermocline "traps" the CH2M HILL North Carolina, Inc.

Page3

Shearon Harris Nuclear Plant - Permit NC#0039586 Jacobs Clarifications to Mixing Zone Modeling & Analysis plume and prevents any surface interaction, the output data showed 100% identical plume data and dilution factors, as expected. Output for the modified Case 4a, using the "Conservative Pollutant" type, is included in Appendix B as a representative sample of these validating model runs.

For the Winter/Spring cases (Cases 1a, 1b, 2a, and 2a}, where the plume is exposed to the surface (and potential atmospheric heat loss}, output data was nearly identical. Output used in the Study (all near-field predictions} was the same for both "Conservative Pollutant" and "Heated Discharge" options. The anticipated mathematical variations in output - due to the difference in treatment of surface heat losses -

were almost undetectable and statistically meaningless (i.e., within the ability of the model to resolve). For example, in Case 1a, the first difference in predicted dilution is notable at a location 1717 m from Outfall 006, where the pollutant TYPE 1 option predicted dilution of 54.4 and the TYPE 3 option predicted 54.5.

3. Parametric Evaluation of Changing Reservoir Levels As with any computer model, simplifying assumptions were made to provide input values to CORMIX that simulate effluent properties and ambient conditions at Outfall 006. These model inputs and assumptions are detailed in Section 3 of the Study TM, including their source and/or basis for their selection.

In accordance with DWR's recommendations, seasonal variations for temperature profiles and effluent flow velocities were captured by running separate model cases for each season and utilizing average or maximum values, as appropriate. Model sensitivity to these key input parameters can be seen in the variation of predicted dilution factors at the acute mixing zone boundary, ranging from 15.3 to 27.2.

For most other inputs, however, static values were selected to best reflect "typical" or "most probable" conditions at Outfall 006. Water depth is an example of this kind of static variable. During the video conference call in November 2020, DWR requested a parametric evaluation be performed to illustrate the model's sensitivity to changes in static inputs, recommending reservoir levels be examined.

3.1 Historic Shearon Harris Reservoir Levels In the Study, water depth parameters (detailed in Section 3.2) were calculated using the Shearon Harris Reservoir normal pool elevation of 220 ft (National Geodetic Vertical Datum [NGVD]). To establish an appropriate range of elevations to use in the requested parametric evaluation, historical data from reservoir level meters in the HNP Primary and Secondary Intake Pumping Station were analyzed.

The table below shows the low (10th percentile), high (90 th percentile), and median daily reservoir levels for the six-year period from January 2015 to November 2020. A copy of the complete data set is included as Attachment D.

TABU:..2 Summary of Daily Reservoir Levels from January 2015 to November 2020 Case 1: Case 2: Case 3: Case 4:

Spring Summer Fall Year --

Winter Dec-Feb Mar-May Jun-Aug Sep-Nov Round Low Water Level 219.8 ft NGVD 219.0 ft NGVD 218.0 ft NGVD 218.8 ft NGVD 217.5 ft NGVD (1<Jh percentile)

High Water Level 220.9 ft NGVD 220.5 ft NGVD 220. 7 ft NGVD 220.8 ft NGVD 221.0 ft NGVD (9<Jh percentile)

Median Level 220.3 ft NGVD 219.8 ft NGVD 219.7 ft NGVD 220.0 ft NGVD 220.3 ft NGVD (S<Jh percentile)

As shown here, Shearon Harris Reservoir levels have been historically stable over the past six years, even in periods of extreme drought. While this supports the use of the normal pool elevation (220 ft NGVD} in the original Study, a parametric evaluation which explores sensitivity to a -2 ft /+1ft variability is helpful in validating the model and clarifying predicted behavior.

Case 4a (Fall season, Maximum Day discharge) was selected for the parametric evaluation, as it was the most restrictive model scenario, predicting the least dilution in the acute mixing zone. Additionally, a Fall Page4 CH2M HILL North Carolina, Inc.

Shearon Harris Nuclear Plant

• Permit NC#0039586 Clarifications to Mixing Zone Modeling & Analysis Jacobs or Summer case is expected to be more sensitive to changes in water level, as the CORMIX model predicts the discharge plume is trapped by the thermocline, restricting the volume available for dispersion.

Of the two seasons with "stratified" conditions, Fall had the greatest pool variability, according to the historic level data.

3.2 Input Parameters Affected by Pool Elevation In the parametric evaluation, two input values were recalculated to adjust for changes in pool elevation:

• Height/Depth at Discharge Location (Ho) - height to the water surface measured from the reservoir floor (sediment bottom); calculated as the difference between pool elevation and estimated bottom elevation at Outfall 006 (175 ft NGVD from available bathymetric survey data)

• Height of Thermocline (HINT) - height to the thermocline measured from reservoir floor; calculated by deducting the depth to the thermocline (estimated to be 5 m [16 ft] below the water surface) from the total Height at Discharge Location (HD)

The calculated input values used in the revised model runs for the parametric evaluation are shown in bold below.

Output for the Low Water Level variation of Case 4a is included in Appendix C. The CORM IX model results are summarized below for the original and alternative scenarios. As described in Section 3.1, the results confirm the plume is impacted by the thermocline, which acts as an upper boundary. Compared to the original Study Case 4a, the low water scenario further restricts the vertical movement of the plume, slightly expanding the width and reducing predicted dilution by less than 2%.

Conversely, the high water scenario raises the thermocline, allowing for a slight increase in vertical movement and narrower plume. The impact on dilution was negligible for the high water scenario.

CORMIX Case 4a (Original & Variations) Results at EPA-defined Acute Mixing Zone Boundary CORMIX Radial Horizontal Plume Centerline Equivalent Effluent Limit Case 4a Distance* Distance* Width Dilution Factor IWC Acute Copper (Daily Max)

Original Study 175.5 ft 278.1 ft 15.3 6.54% 166.1 µg/L High Water Level 177 ft 175.6 ft 277.0 ft 15.3 6.54% 166.1 µg/L Low Water Level 175.9 ft 279.6 ft 15.0 6.67% 163.0 µg/L -1 .9%

Notes:

a The radial distance is a vector distance from the center of the port, while the horizontal distance reflects the x-direction only (plan view, looking down at the surface of the waterbody)

For purposes of dilution at an acute mixing zone boundary, the Low Water Level Case 4a represents a "worst-case of the most conservative case" scenario. Notably, the predicted dilution factor at the acute mixing zone boundary of 15.0 is equivalent to an effluent limit of 163.0 µg/L, which is greater than double the maximum value measured at Outfall 006.

Jennifer Bell added that the modeling approach looked at the most conservative scenarios and that the team is ready to evaluate sensitivity.

3) Application of Mixing Zone Results to Water Quality Criteria:

Jennifer Bell reviewed Duke's recommended approach for incorporating mixing zone results into the calculation of water quality criteria. Once a mixing zone is defined, water quality criteria are calculated at the edge of the mixing zone. Hardness data are incorporated as well. NCDEQ does not have written guidance and Duke evaluated potential water quality criteria using EPA and Wisconsin guidance. No further discussion was had.

4) Next Steps Forward:

Don Safrit stated that Duke is receptive to refining the findings and then determining outcomes of an evaluation of appropriate water quality criteria. Don asked that DEQ provide written comments so that this can be resolved expeditiously ahead of or in parallel with the permit renewal process.

Duke understands that DEQ cannot provide additional feedback on water quality criteria until comments on mixing zone study are addressed.

David Hill stated that DEQ aims to provide written mixing zone study comments within 30 days.

Duke will plan to address those comments within the following 30 days.

David Hill asked if other DEQ industrial permitting staff had comments or questions. None were provided. This concluded the call.

• North Carolina rules allow m1xmg zones but provide little spec1fic1ty for determining characteristics

• EPA created the Technical Support Document (]SD") in 1991 for regulating toxic substances such as copper; incl des guidance on I --

mixing zones:

- Significant overall detail for establishing mixing zo es; general in nature

- Provides guidance for acute mixing zone definition

- No specific guidance for chronic mixing zones

• Wisconsin developed detailed mixing zone rules and guidance:

- Chronic mixing zone for lakes based on edge of dtcharge-induced mixing

- Includes a default dilution ratio for chronic mixing f 1O: 1 Source: Duke Energy, Environmental Monitoring Reports for 2016-2018 ef':')DUKE cl_~DUKE

Wedge length 117104.l m X*Positlon of wed1e tip -116907 m Thickness at discharge (end of NFR) 6.02 m (Wedge thickness gradually decreases to zero at wed1e tip.)

In this case, the upstream INTRUSION IS VERY LARGE, exceeding 10 times the local water depth.

This may be caused by very small ambient velocity, perhaps in :om bl nation with large discharge buoyancy.

If the ambient conditions are strongly transient (e.g. tidal), then the CORMIX iiteady-stattpredlctlons of upstream intrusion are probably unrealistic.

Note:

CORMIX is steady state model and assumes discharee and ambient conditions do not vary over time. The predicted plume cumulative travel time exceeds 48 hours at this trajectory distance. Keep In mind that ambient and dlscharce conditions are likely to vary over lar1e space and time scales. Predictions at such large space and time scales may be Inconsistent with CORMIX modelln1 ,ssumptlons.

Please carefully evaluate your simulation results and llmlt model 1terpretatla to space and time scales consistent with steady state tssumptlon: and ambient hematlzatlon.

• • End of NEAR-FIELD REGION (NFR) **

The initial plume WIDTH values In the next far-field module will be CORRECTED by a factor 3.84 to conserve the mass flux in the far-field I The correction factor is quite large because of the small ambient velocity relative to the strong mixing characteristics of the discharge I This indicates localized RECIRCULATION REGIONS and INTERNAL HYDRAULIC JUMPS.

Width predictions show discontinuities. Dilution values should be acceptable.

• Some BOUNDARY INTERACTION with both banks occurs at end of near-field.

The dilution values in one or more of the preceding zones may be too high.

Carefully evaluate results in near-field and check degree of interaction.

BEGIN MOD181: MIXED PLUME/BOUNDED CHANNEL/POSSIBLE UPSTREAM WEDGE INTRUSION An UPSTREAM INTRUDING WEDGE is formed along the surface/pycnocline.

UPSTREAM WEDGE INTRUSION PROPERTIES in bounded channel (laterally uniform):

Wedge length = 11893.14 m X-Position of wedge tip = -11696.37 m Thickness at discharge (end of NFR) = 5.81 m (Wedge thickness gradually decreases to zero at wedge tip.)

In this case, the upstream INTRUSION IS VERY LARGE, exceeding 10 times the local water depth.

This may be caused by a very small ambient velocity, perhaps in combination with large discharge buoyancy.

If the ambient conditions are strongly transient (e.g. tidal), then the CORMIX steady-state predictions of upstream intrusion are probably unrealistic.

The plume predictions prior to boundary impingement and wedge formation will be acceptable, however.
