Executive Summary 316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT On August 15, 2014, regulations implementing §316(b) of the final Clean Water Act (CWA) rule for existing facilities (the Rule) were published in the Federal Register with an effective date of October 14, 2014.

Facilities subject to the Rule are required to develop and submit technical material, in accordance with

§122.21(r), that will be used by the National Pollutant Discharge Elimination System (NPDES) permit Director (Director) to make a Best Technology Available (BTA) determination for the facility.

Harris Nuclear Plant (HNP) began commercial operations in May 1987 and was permitted in pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency (NC0039586).

Based on the §122.21{r) submittal material provided herein, HNP's selected method of compliance with the Impingement Mortality Standard is the continued operation of a closed-cycle recirculating system.

Further, HNP requests that the Department designates the existing closed-cycle system as Best Technology Available {STA) for entrainment reduction. Give that HNP currently employs closed-cycle cooling as described below, no further impingement or entrainment controls are necessary to comply with the standards.

Impingement BTA The final Rule, at §125.94(c), requires existing facilities to employ one of seven impingement BTA alternatives 1. HNP already employs two of these alternatives:

Primary impingement BTA-Closed-cycle cooling with a natural draft cooling tower is utilized to provide makeup water which is consistent with a closed-cycle recirculating system (CCRS) defined at §125.92(c) and meets the BTA Standards for Impingement Mortality at §125.94(c)(l).

Accordingly, this is HNP's preferred option for complying with the impingement standard.

Entrainment BTA The Rule does not prescribe BTA for entrainment but does require BTA to be determined by the permitting authority on a site-specific basis. Based on the information presented in this report, HNP requests that the Department designate closed-cycle cooling at HNP as BTA for entrainment based on the following:

When compared against the factors in 40 CFR § 122.25(f), an existing closed-cycle cooling system provides benefits to entrainment relative to once-through cooling (OTC) without additional costs.

The HNP uses closed-cycle cooling, which minimizes entrainment through flow reduction. The flow reduction achieved is calculated at 91% flow reduction based on design flow and 365 days 1 Or under specific circumstances one of nine alternatives, which includes §125.94(c)(ll) and (12) in addition to

§125.94(c)( 1)-(7).

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT per year operation. Generally, only one CTMU pump is operated which results in a more realistic flow reduction of approximately 95%. Using actual CTMU flows during the 2016-2018 period, the withdrawal reduction is 97.2%.

Statements made by the United States Environmental Protection Agency (EPA) in the preamble to the Rule support a conclusion that an existing closed-cycle cooling system is appropriate for designation as BTA for entrainment:

"Although this rule leaves the BTA entrainment determ;notion to the Director, with the possible BTA decisions ranging from no additional controls to closed-cycle recirculating systems plus additional controls as warranted, EPA expects thot the Director, in the site-specific permitting proceeding, will determine that facilities with properly operated closed-cycle recirculating systems do not require additional entrainment reduction control measures. "2 (emphasis added)

This conclusion is further reiterated In the Response to Public Comments document, where EPA states:

"EPA hos mode it clear that a facility that uses a closed-cycle recirculating system, as defined in the rule, would meet the rule requirements for impingement mortality at§ l25.94(c}(l). This rule language specifically identifies closed-cycle as a compliance alternative for the [impingement mortality]

performance standards. EPA expects the Director would conclude that such a facility would not be subject to additional entrainment controls to meet BTA. "3 (emphasis added)

Overall, entrainment at the facility Is low and is not expected to involve federally protected species or their designated critical habitat. Potential impacts to fish and shellfish populations at HNP due to entrainment is also extremely unlikely due to the operation and configuration of the intake. Based on these findings, the existing closed-cycle cooling system is the best technology available for reduction of entrainment.

1 Introduction 316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT Section 316(b) was enacted under the 1972 Clean Water Act (CWA), which also introduced the National Pollutant Discharge Elimination System (NPDES) permit program. Certain facilities with NPDES permits are subject to §316(b) requirements, which require the location, design, construction, and capacity of the facility's cooling water intake structure (CWIS)4 to reflect Best Technology Available (BTA) for minimizing potential adverse environmental impacts.

On August 15, 2014, regulations implementing §316(b) of the final CWA rule (Rule) for existing facilities were published in the Federal Register with an effective date of October 14, 2014. The Rule applies to existing facilities that withdraw more than 2 million gallons per day (MGD) from waters of the United States, use at least 25 percent of that water exclusively for cooling purposes, and have or require an NPDES permit.

Facilities subject to the Rule are required to develop and submit technical material that will be used by the NPDES Director (Director) to evaluate an applicant's preferred technology for compliance with the impingement standard and to make a site-specific Best Technology Available (BTA) determination regarding entrainment for the facility. The actual intake flow (AIF)5 and design intake flow (DIF)6 at a facility determines which submittals will be required. As shown in Table 1-1, facilities with an AIF of 125 MGD or less have fewer application submittal requirements and will generally be required to select from the impingement compliance options contained in the final Rule. Facilities with an AIF in excess of 125 MGD are required to address both impingement and entrainment, and provide specific entrainment studies, which may involve extensive field studies and the analysis of alternative methods to reduce entrainment (§122.21(r)(9)-(13)).

The §316(b) compliance schedule under the Rule is dependent on the facility's NPDES permit renewal date. Facilities were required to submit their §316(b) application material to their Director with their next permit renewal application unless that permit renewal application was due prior to July 14, 2018, in which case an alternate schedule could have been requested.

4 CWIS is defined as the total physical structure and any associated constructed waterways used to withdraw cooling water from Waters of the United States. The CWIS extends from the point at which water is first withdrawn from waters of the United States up to, and including, the intake pumps.

s AIF is defined as the average volume of water withdrawn on an annual basis by the cooling intake structure over the past 3 years initially and past 5 years after Oct. 14, 2019. The calculation of AIF includes days of zero flow. Alf does not include flows associated with emergency and fire suppression capacity.

5 DIF is defined as the value assigned during the CWIS design to the maximum instantaneous rate of flow of water the CWIS is capable of withdrawing from a source waterbody. The facility's DIF may be adjusted to reflect permanent changes to the maximum capabilities of the cooling water intake system to withdraw cooling water, including pumps permanently removed from service, flow limit devices, and physical limitations of the piping. DIF does not include values associated with emergency and fire suppression capacity or redundant pumps (i.e., back-up pumps).

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT 2.1 Description of Source Waterbody [§122.21(r)(2)(i)]

HNP is a nuclear-powered electrical generation facility located in the southwest corner of Wake County, North Carolina. Portions of HNP site also lie in southeastern Chatham County. HNP consists of one pressurized light water reactor nuclear steam supply system and turbine generator rated at 992 megawatts with a cooling tower-based heat dissipation system. HNP began commercial operation in May 1987. A 4,150-acre main reservoir was constructed to serve as the source of cooling tower makeup. A smaller, 321-acre auxiliary reservoir was also constructed to serve as the primary source for the Emergency Cooling Water System, which is designed to remove heat from the reactor and critical components following a loss-of-coolant accident or a loss of off-site power.

HNP has two cooling water intake structures; one (Emergency Service Water and Cooling Tower Makeup Intake Structure) on the main reservoir (aka Harris Reservoir}, from which cooling tower makeup water is obtained, and one (Emergency Service Water Intake Screening Structure} on the auxiliary reservoir (aka West Reservoir), from which water is obtained for the plant's Emergency Service Water (ESW)

System. Harris Reservoir is a freshwater reservoir located in Chatham and Wake Counties, North Carolina. The reservoir was created by impounding Buckhorn Creek, a tributary of the Cape Fear River.

The main body of Harris Reservoir has a surface area of approximately 4,150 acres, a maximum depth of 18 meters, a mean depth of 5.3 meters, a volume of approximately 8.9 x 107 cubic meters, a full-pool elevation of 67.1 meters National Geodetic Vertical Datum (NGVD) [220 ft], and an average residence time of 28 months. The reservoir began filling in December 1980 and full pool elevation was reached in February 1983. The 40-mile shoreline is mostly wooded, and the 71-square mile drainage area is mostly rolling hills with land used primarily for forestry and agriculture. A smaller 317-acre auxiliary reservoir was also built to serve as the primary source for the Emergency Colling Water System, which is designed to remove heat from the reactor and critical components following a loss-of-coolant accident (LOCA) or a loss of off-site power (LOOP).

From its headwaters east of HNP near Fuquay-Varina, Buckhorn Creek flows in a southwesterly direction for most of its length, then moves south to its confluence with the Cape Fear. Buckhorn Creek has five tributaries above the Harris Reservoir dam; Tom Jack Creek, Thomas Creek, little White Oak Creek, White Oak Creek and Cary Branch (HNP FSAR). Buckhorn Creek and its tributaries drain an area of 76.3 square miles (USGS 2004). Flows in Buckhorn Creek showed dramatic daily and seasonal fluctuations prior to the development of Harris Reservoir, but are now regulated by the Harris Reservoir dam. From 1981 to 2016, annual mean streamflow (measured at USGS station 02102192 located approximately one mile downstream of the dam) ranged from 1.33 to 137 cubic feet per second.

2.1.1 Water Quality Surface water dissolved oxygen in Harris Lake ranged from 5.2 to 8.5 mg/Land surface water pH ranged from 6.9 to 7.6 s.u (Appendix A). Secchi depths were at or greater than a meter at all three lake sampling sites (range= 1.0 to 1.6 meters), indicating that the water clarity was good. Total phosphorus ranged from 0.02 to 0.05 mg/Land total Kjeldahl nitrogen ranged from 0.62 to 0.77 mg/L. Nitrite plus nitrate concentrations were less than the laboratory detection level of 0.02 mg/Land ammonia ranged from <0.02 to 0.05 mg/L. Chlorophyll a values ranged from 9.3 to 41.0 ug/L, the latter of which was the single value that was greater than the state water quality standard of 40.0 ug/L for chlorophyll a.

Based on the calculated North Carolina Trophic State Index scores for the growing season of 2013, Harris Lake was determined to exhibit elevated biological productivity or eutrophic conditions. This 9

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT reservoir was also determined to be eutrophic in 2003 and 2008 when it was last monitored by the North Carolina Division of Water Resources (DWR) (DWR Intensive Survey Unit 8/4/2014).

Duke Energy Progress conducted an environmental monitoring program in 2012 at Harris Lake to assess the reservoir's overall water quality, identify potential introduction and expansion of invasive plant and animal species to the reservoir and to demonstrate the existence of a recreational fishery in the lake. In this study, Harris Lake was found to have high biological productivity with chlorophyll a values ranging from 3 to 37 ug/L. Biological surveys identified the presence of Asiatic clams (Corbiculo fluminea) as well as the invasive plants hydrilla (Hydrilla verticillata) and Creeping Water Primrose (Ludwigia uruguayensis).

2.2 Characterization of Source Waterbody [§122.21(r)(2)(ii)]

To identify and characterize the primary source water body (i.e., Harris Reservoir) the following resources were reviewed and summarized:

Environmental Monitoring Reports 2008, 2010, 2012, 2014, 2016 These data were compiled and analyzed for this report and are summarized below. This report was developed utilizing the existing, available data for Shearon Harris Reservoir.

The Harris Reservoir shoreline is mostly wooded; the drainage area is mostly rolling hills with land used primarily for silviculture and agriculture. Although the immediate watershed is forested, the expanding towns of Apex and Holly Springs are to its north and east, respectively. The HNP facility NPDES permit (NCNC0039586) regulates discharges to the reservoir. The reservoir also receives treated discharge from a wastewater treatment plant in Holly Springs via Utley Creek (a tributary of White Oak Creek),

which flows into Harris Reservoir's northeastern-most arm.

An analysis of land use coverage in 2004 showed more than 70 percent of the sub-basin (which includes several watersheds, including the Buckhorn Creek-Harris Reservoir watershed) is forested (NCDENR 2004a). However due to accelerated urban growth especially around the towns of Holly Springs and Fuquay-Varina, the amount of land in pasture, cultivated crops, and forest will probably continue to decrease while the amount of land committed to residential and commercial uses will increase.

Harris Reservoir was classified by North Carolina Department of Environmental Quality as eutrophic in the agency's most recent Basinwide Assessment Report (NCDENR 2004a, pages 89, 93, and 94). The reservoir was sampled by the agency in 2003. At that time, despite heavy rainfall in the watershed, Secchi depths were greater than one meter at all sampling sites. Fecal coliform bacteria concentrations were low. Total phosphorus concentrations were similar to those previously measured. Ammonia concentrations were consistently below detection level at all sites and these concentrations were the lowest ever observed. Aquatic macrophytes, including Hydrilla sp., were observed throughout the reservoir. NCDENR classified Harris Reservoir as eutrophic based on calculated North Carolina Trophic State Index scores (which are in turn based on water clarity, algal densities, and phosphorus concentrations); it had received this classification in previous monitoring cycles as well.

Duke Energy Progress, formally Progress Energy, has monitored water quality and biological communities in Harris Reservoir since the reservoir filled, in the early 1980s, in an effort to evaluate the waterbody's health, track changes in water quality, document the appearance of nonnative plants and 10

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT animals, and assess the recreational fishery. Water quality (including temperature, dissolved oxygen, pH, and turbidity), water chemistry (including major nutrients and various trace metals), fish have been sampled quarterly and aquatic vegetation once annually (Progress Energy 2003a, pp. 4-6, Duke Energy Progress 2016}.

Like several other impoundments in piedmont of North Carolina, Harris Reservoir is a biologically productive reservoir. Harris Reservoir has many of the characteristics of eutrophic southeastern reservoirs including elevated nutrient concentrations, extensive growth of aquatic vegetation in shallows, oxygen-deficient hypolimnetic water in summer (Duke Energy Progress 2016 The nearest USGS gage station is located at Buckhorn Creek near Corinth, North Carolina (USGS 02102192). The drainage area of this gaging station is 76.3 square miles. Downstream from Harris Nuclear Plant on the Cape Fear River near Lillington, North Carolina is a USGS gaging station (02102500).

USGS 02098206 Haw River near Monclure, North Carolina, is located upstream from the mouth of the Cape Fear River and has a drainage area of 1,691 square miles (Figure 2-3).

The estimated drainage area of the Cape Fear River Basin is approximately 9,164 square miles.

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT The HNP is located in the Piedmont physiographic province near the fall line separating the Coastal Plain from the Piedmont (FSAR p. 2.4.13-1). The site is located within the southeastern portion of the Durham Basin and is underlain by rocks of the Triassic Newark Group. The plant area is covered by residual soils derived from the underlying rock which consists of claystone, shale, siltstone, sandstone, conglomerate, and fanglomerate (FSAR p. 2.4.13-1). The surficial clay soils and saprolite prevent ready recharge to the rocks below (FSAR p. 2.4.13-2).

Vegetation at most of the HNP site is typical of the eastern Piedmont province of North Carolina (CP&L 1982). Forests at HNP are in various stages of ecological succession and consist of pine forest, hardwood forest, or pine-hardwood mixtures. loblolly pine (Pinus toeda) dominates the pine forests, but shortleaf (P. echinoto), Virginia (P. virginiono), and longleaf (P. pollustris) are also found at the site.

Hardwood forests at HNP are found primarily in lowland areas along streams. Dominant lowland forest species are sweet gum (Liquidambor styraciflua), red maple (Acer rubrum), American sycamore (Platonus occldento/is), American elm (Ulnus americano), and river birch (Betula nigra). Most of the upland forests at HNP are a mixture of pines (Pinus spp.), oaks (Quercus spp.) and hickories (Carya spp.)

(NRC 1983).

Harris Reservoir provides some limited marsh habitat in shallow backwaters. These marshes and adjacent shallows are used by waterfowl such as the mallard (Anos p/atyrhynchos), wood duck (Aix sponso), and Canada goose (Branta canodensis), and wading birds such as herons and egrets. A great blue heron (Ardea herodias) rookery, known to be active during recent breeding seasons, is located at the mouth of Jim Branch in the southeastern portion of Harris Reservoir.

Cooling Water Intake Structure Data [§ 122.21(r)(3)]

The information required to be submitted per 40 CFR §122.21(r)(3), Cooling Water Intake Structure Data, is outlined as follows:

(i)

A narrative description of the configuration of each of the cooling water intake structures and where it is located in the waterbody and in the water column; (ii)

Latitude and longitude in degrees, minutes, and seconds for each of the cooling water intake structures; (iii)

A narrative description of the operation of each of the cooling water intake structures, including design intake flows, daily hours of operation, number of days of the year in operation and seasonal changes, if applicable; (iv)

A flow distribution and water balance diagram that includes all sources of water to the facility, recirculating flows, and discharges; and (v)

Engineering drawings of the cooling water intake structure.

Each of these requirements is described in the following subsections.

3.1 Description of CWIS Configuration [§122.21(r)(3)(i)]

HNP has two cooling water intake structures but only one is equipped with cooling water makeup (intake) pumps.

The first structure is the Cooling Tower Makeup and Emergency Service Water Intake Structure (CTMUESW). It is located at the end of a canal that stems from an arm of the Harris Reservoir. This structure Is equipped with two Coollng Tower Makeup (CTMU) pumps, each rated at 26,000 gallons per minute (gpm), and two Emergency Service Water (ESW) pumps, each rated at 21,000 gpm. The structure was constructed with 14 bays but only two bays are used for the CTMU pumps and two bays are used for the ESW pumps. The remaining 10 bays are unused and do not have any pumps. Each of the ESW pump bays have a concrete dividing wall with an eight by ten foot butterfly valve. The dividing wall butterfly valve arrangement along with pipe valving permits operation of the EWS pumps by accessing water from either the main or auxiliary reservoir. The CTMU pump bays are each equipped with traveling screens with 3/8-inch openings. The ESW pump bays are fitted with traveling screens with 3/8-inch openings. Normal water elevation is 220 feet. The invert to the suction for the pumps in located at approximately 191.5 feet.

The second intake structure is the Emergency Service Water Intake Screening Structure which is located at the end of a canal coming from the auxiliary reservoir. This structure has no cooling water intake pumps and functions only as an alternate screened intake opening for water withdrawal by the two ESW pumps located at the CTMUESW. This structure has traveling screens with 3/8-inch opening. The normal water elevation in the auxiliary reservoir is 250 feet and the invert to the conveyance pipes is approximately 233.3 feet in elevation. The structure does have two screen wash pumps (@500 gpm) 14

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT which are operated about one hour per year each; two fire protection system pumps (@3000 gpm) which are operated about 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months per year each; and one fire jockey pump with negligible flow rate and run time.

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT 3.3 Description of CWIS Operation [§122.21{r)(3)(iii)]

Under normal design operating conditions, the cooling water flow of HNP is 538,000 gallons per minute (gpm). This total includes circulating water (487,000 gpm) and Normal Service Water (50,000 gpm) flows, apportioned as follows: three circulating water pumps@ 162,300 gpm each (Progress Energy 2003d) and two NSW pumps @ 25,000 gpm each (Progress Energy 2003c). After passing through the main condenser, cooling water (combined flow of circulating water and service water) is routed to a 100 percent capacity, 523-foot-tall, hyperbolic natural-draft cooling tower where the bulk of the waste heated is removed (Progress Energy 2003b). The tower is designed to remove 6.663 X 109 BTU/hr at the design flow rate of 538,000 gpm and reduce water temperature 25 degrees F.

Cooling Tower Makeup Pumps (two located in the ESW and CTMU Intake Structure) supply makeup water from the main reservoir. Each Cooling Tower Makeup (CTMU) Pump has a 26,000 gpm capacity.

Normally, one CTMU pump operates continuously, supplying makeup water to the cooling tower, while the other is kept in reserve. One pump supplies all the necessary makeup water to replace losses to drift, evaporation, and blowdown.

Under certain extraordinary circumstances, CTMU pumps are also used to transfer water from the main reservoir to the auxiliary reservoir. When drought limits the amount of water entering the auxiliary reservoir and water levels drop beyond those considered optimal for safe operations, water is pumped from the main reservoir to the 321-acre auxiliary reservoir. This typically requires 2 to 3 days of pumping in drought years.

Finally, HNP has a non-recirculating Emergency Service Water system that allows the pumping of water from the auxiliary reservoir or the main reservoir to various essential components following a loss-of-coolant accident or loss of off-site power. This system, which is tested periodically to ensure reliability, is equipped with two 20,000 gpm pumps. Under typical circumstances, one of these pumps is operated while the other is kept in reserve.

The number of CWIS operating hours from 2016 to 2018 is provided in Table 3-1. During these 3 years, CWIS operated 8,760 hours0.0088 days 0.211 hours 0.00126 weeks 2.8918e-4 months per year (i.e., 100 percent of the time). Note this should not be confused with the capacity factor of the HNP facility. Plant outages typically occur in the spring and/or fall each year.

3.5 Avoided Withdrawals Due to Cooling Tower Utilization The utilized natural draft cooling tower provides effective reductions in withdrawals. Assuming that the cooling water withdrawal without cooling towers would be the combined flow from the circulating water pumps (774.15 MG0) and the normal service water pumps (72.00 MGD), the total comparable once-through cooling withdrawal would be 846.15 MGD. As the actual withdrawal of water used for makeup to the cooling tower is only 23.5 MGD, the reduction is expressed by:

[1 * (23.5 MGD / 846.15 MGD))

100 = 97.2%

4.2 List of Species and Relative Abundance in the vicinity of CWIS

[§ 122.21( r)(4)(ii)]

Duke Energy has monitored the fish community in Harris Reservoir and near the CWIS since 1975 using electrofishing and other gear types. The following sections describes the results of boat electrofishing surveys on Harris Reservoir from 2008-2016, the fish assemblage summary based on a composite of survey locations from 2008-2016, and summaries of the fish community composition and their relative abundance from 2008-2016 for Transect P and V.

2008-2016 Sample Transects Fish were sampled with boat electrofishing at Transects E, H; P, S, and V (Table 4-1, Fig 4-1). Transect V is adjacent to the CWIS and is in the hydraulic zone of influence and near-field to the CWIS (Fig 4-2).

Transect Pis approximately 2.3 km downlake ofV and is far. field in relation to the CWIS. The other monitoring Transects, E, H, and Sare approximately 7.1 km, 10.5 km, and 6.4 km from V, respectively.

Each monitoring transect consisted of two, fixed position stations situated on opposite shorelines from each other, for a total of 10 stations (El, E3, Hl, H3, P2, P3, Vl, V3.) that were sampled quarterly in even years (2008, 2010, 2012, 2014, 2016). The stations and quarterly samples at each transect were combined annually to produce the fish community summaries and relative abundance.

Boat electrofishing was conducting following standard methods (Murphy and Willis 1996) and Duke Energy Internal procedures. Electrofishing was conducted for 900 seconds (15 minutes) of effort at each station (10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months annual total effort across all stations and transects). Fish were identified to the species level when possible using regional taxonomic references (Menhinick 1993, Jenkins and Burkhead 1994), measured for total length (TL) to the nearest millimeter, and weighed to the nearest gram. Fish that could not be accurately identified in the field were preserved with 10 percent buffered formalin solution and transported to the laboratory for identification and body measurements. Each specimen was examined for hybridization, anomalies, disease, parasites, and general condition. Photographs were also taken of fish with any deformity or anomaly. Some specimens were retained in 70 percent ethanol for identification in the laboratory and for voucher purposes.

In total there were 27 species of fish (excluding hybrids) collected on Harris Reservoir from 2008 to 2016. There were 25 species of fish encountered at Transect E, followed by V with 22, S with 20, H with 19, and P with 18 species. Differences in species assemblages between transects were attributed to 22

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT species that were low in abundance and characterized as being less than 0.5% of the total fish assemblage. The transects also had some differences in habitat such as presence of aquatic macrophytes, water depth and structure. Species common to all transects were generally greater than 1% of the community assemblage. The fish community is representative of a typical southeastern reservoir sportfish and forage fish assemblage comprised of(% fish community composition) Bluegill (40%), Threadfin Shad (19%), Redear Sunfish (15%), Largemouth Bass (12%), Gizzard Shad (4%), White Perch (2%), Golden Shiner (2%}, and Black Crappie (1%) (Table 4-2). The fish community composition for each of the years that were sampled (2008, 2010, 2012, 2014, 2016) had similar composition percentages between years.

The most numerous species collected in the reservoir from 2008 to 2016 (Table 4-3) were Bluegill (54.5-178.1 Fish/Hour), followed by Threadfin Shad (7.5-92.9 Fish/Hour), Redear Sunfish (23.8-54.8 Fish/Hour), Largemouth Bass (18.4-52.5 Fish/Hour), Gizzard Shad (4.3-15.7), and Black Crappie (0.4-10.4 Fish/Hour).

1 0,5 2.5 Common Carp, which were stocked everywhere for decades by the U.S. Fish Commission beginning the late 1870's (Cole 1905), are considered exotic and potentially invasive and have been collected in Shearon Harris Reservoir. White Perch, which were first observed in the reservoir during 1996 from an undocumented stocking, are not exotic, but are non-native to the interior waters of North Carolina and could be considered invasive. These fishes do not appear to be having an impact on the extant reservoir fish community. The presence and operation of the CWIS has not contributed to the presence of the 29

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT exotic or invasive species nor has the structure contributed to the decline of the established fishes in the reservoir.

4.3 Identification of Species and Life Stages Susceptible to Impingement and Entrainment [§122.21(r)(4)(iii)]

The CWIS design, with a TSV of less than 0.5 fps, is compliant with impingement BTA requirements of the Rule. As such, no species or life stages are anticipated to be susceptible to impingement at the Shearon Harris CWIS. To the extent any species may have the potential to be entrained, based on the operational parameters of the CWIS on Shearon Harris Reservoir (low 0IF and TSV), interactions with aquatic organisms are expected to be limited with no potential for adverse environmental impacts.

4.3.1 Impingement The degree of vulnerability to impingement exhibited by adult and juvenile fish species depends upon biological and behavioral factors including but not limited to: Seasonal fish community structure, spawning effects on distribution, habitat surrounding intake structures, water quality stressors, high flow events, and the location and attraction to the flow associated with the intake. In addition, swimming speed, intake velocity, screen mesh size, trash rack spacing, and other intake configurations will also affect the susceptibility to impingement. For example, clupeids have high susceptibility to impingement based on multiple factors such as schooling behavior, distribution in the water column, negative rheotactic response to intake flows, and poor swimming performance in winter months due to lower water temperatures (Loar et al 1978).

No ongoing or historical impingement studies have been performed at the CWIS on Shearon Harris Reservoir. The CWIS withdraws water from Harris Reservoir through traveling screens with a design TSV of less than 0.5 fps. In the Rule, intake screens designed to achieve a TSV at or below 0.5 fps are compliant with the impingement reduction standard.

Species with floating eggs would continue to have some susceptibility to entrainment 4.3.3 Selected Species A subset of species present in Shearon Harris Reservoir with the likelihood to be entrained was selected for detailed life history descriptions including reproduction, recruitment, and peak abundance.

Threadfin Shad and Gizzard Shad were selected as target species because of reproduction (i.e.,

broadcast spawner or floating eggs). Bluegill was also selected as a target species because it was the most abundant species in historic electrofishing collections, is a substantial contributor to the recreationaJ fishery, and is an important forage species for game fish. Other selected species that contribute to the recreational fishery of Shearon Harris Reservoir and were among the most dominant species collected in historic electrofishing sampling include Redear Sunfish, Largemouth Bass, White Perch, Golden Shiner, and Black Crappie.

32

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT Of the selected species, two (i.e., Threadfin Shad and Gizzard Shad) are recognized as having the highest potential for entrainment at the CWIS. The species account descriptions below are ordered from most abundant to least.

Threadfin Shad Spawning occurs in shallow waters such as near shorelines or riverbanks. Threadfin Shad spawn from April to July in water temperatures above l6°C between dawn and sunrise (Jenkins and Burkhead 1993; Rohde et al 2009) (Citation). Spawning occurs near the shoreline and over aquatic plants and other submerged objects with eggs that are demersal and adhesive. Threadfin Shad are sensitive to sudden changes in water temperature and oxygen content resulting in frequent die-offs in late summer and winter (Jenkins and Burkhead 1993; Rohde et al 2009). (Citation). This species is not considered fragile but are similar to the fragile classified Gizzard Shad in their biology, physiology, and morphology. The Threadfin Shad similar enough to Gizzard Shad to warrant treatment as a fragile species in this report.

Gizzard Shad Gizzard Shad are classified by the EPA as a fragile species (Table 4-10). Gizzard Shad spawning can occur from mid-March to late August, with peak population spawning in May and June at water temperatures ranging from 15.6-22.S"C (Wallus et al. 1990). They spawn in large schools and their adhesive eggs are deposited on roots, fibers, and debris along the shore (Miller 1960). Gizzard Shad are extremely prolific spawners and can deposit as many as 400,000 eggs at one time (Tomelleri and Eberle 1990).

Bluegill Bluegill occur in most rivers and lakes in the southeastern U.S. and are frequently found in backwater habitats containing vegetation and woody debris. Bluegill spawn at water temperatures between 19.4 and 26.7"C (Cornish and Welke 2004; Spotte 2007). The spawning season begins in spring or early summer when the water temperature reaches approximately 21.1 *c with the peak of spawning in the mid-Atlantic region occurring in May or June. Individual fish may spawn several times within the same season (Rohde et al. 1994).

Bluegill are colonial breeders and build nests to spawn in that are usually in close proximity to each other. Males construct nests that are approximately 1 foot in diameter in shallow water (i.e., depths of 1 to 3 feet). The eggs from several females can be fertilized and deposited in the nest, which is then defended by the male until the eggs have hatched. Because the nests are located in shallow depths, water level fluctuations can severely impact successful reproduction as nests can be stranded by low water level or disrupted by strong wave action. The adhesive eggs hatch after 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months at 22.2°C and 34 hours3.935185e-4 days 0.00944 hours 5.621693e-5 weeks 1.2937e-5 months at 26.7°C (Cornish and Welke 2004). The yolk sac is absorbed when larvae are 6 millimeters long, at which time they leave the nest and move into littoral vegetation. Fry are free swimming after approximately 10 days (Carlander 1977). Fecundity ranges from 2,000 to 8,000 eggs at age 3 and up to 60,000 eggs at ages 4 to 8.

RedearSunfish Redear Sunfish inhabit a variety of habitat including vegetated ponds, lake, reservoirs, pool and backwater of streams and small rivers over mud or sandy bottoms (Jenkins and Burkhead 1993).

Spawning starts, usually in synchrony, in May when water temperatures reach 20 to 21

C and can 33

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT continue into mid-summer. Redear Sunfish are colonial breeders and build nests in close proximity to each other in water shallower than two meters. Females can produce from 12,000 to 30,000 demersal sticky eggs. Males guard the eggs and fry in the nests. Redear Sunfish consumes a wide variety of insects, but due to large molariform teeth, the fish also crushes and eats snail, small mussels and clams.

Largemouth Bass Largemouth Bass spawn when water temperatures reach 15.6-23.9 °c (Heidinger 1975). The male builds a nest in substrate typically comprised of rocky sand or gravel and cleared of organic debris and silt (Emig 1966; Rohde et al. 1994; Pflieger 1997). The nests are 2 two 3 feet in diameter and usually widely spaced (i.e., 30 feet apart) unless the available nesting area is limited. Nests are built in areas of no current or wave action (Pflieger 1997) at depths of 1 to 15 feet.

Males remain at the nest to fan the eggs to keep them silt-free and to protect the young for up to two weeks (Pflieger 1997). Eggs hatch in 2 to 5 days (Emig 1966) and the fry form tight schools over the nest and begin to feed in five to eight days. The schools break up approximately 1 month after hatching when the young bass are approximately one inch long. Growth rates are variable and depend on the lake productivity and food availability. Largemouth Bass typically mature at about ages 1 to 2 in the region (Carlander 1977; Rohde et al. 1994), or when they reach approximately 10 inches long (Pitlo et al. 2004).

White Perch White Perch are native to Atlantic slope rivers and are a semianadromous species typically found in lower and mid-estuary areas that make spawning runs into upstream reaches of rivers. White Perch have been introduced into may freshwater reservoirs inside and outside of their native range. They were first observed in Shearon Harris Reservoir in 1996. White Perch are broadcast spawners and can produce from 20,000 to 150,000 adhesive and demersal eggs (Jenkins and Burkhead 1994). Spawning occurs in aggregations and takes place when temperatures are between 10 and 16° C during a one to two-week period. Peak spawns may occur in Shearon Harris in February, March, or April. Spawning takes place on primary points (rather than secondary points in embayment areas), on cover-free shallow sloping points that have hard/sand clay features (Wong 2002). White perch are opportunistic feeders and eat insects, zooplankton and fishes. Older fishes concentrate on young of the year shad when available (Wong 2002). White Perch school in open water and are found in shallow to moderate depths for most of the year but move to deeper water during the winter. In reservoirs, White Perch can occupy similar areas as Black Crappie.

Golden Shiner The Golden Shiner is widely distributed throughout eastern North America and found in a variety of habitats including streams, river, ponds, lake, and reservoirs. The shiner typically associates with vegetation and often swims in schools in alongside vegetation shorelines (Jenkins and Burkhead 1994).

The Shiner feeds on plankton from midwater to surface depths and will often follow the plankton daily migration. Midge larvae, microcrustaceans, and insects are also a component of the diet. Spawning may occur from April through August from 15 to 26° C. Adhesive eggs are cast over rooted aquatic vegetation, filamentous algae, gravel, and sometimes on the nests of black basses and sunfishes (Etnier and Starnes 1993). Females can produce up to 200,000 eggs. Sexual maturity is reached at two years of growth usually at lengths of 65-80 mm.

[§ 122.21(r)(4)(iv)]

Fish are cold blooded, thus primary growth occurs when water temperatures are l0°C or above. The conventional view on seasonal variation in fish growth in North America is that growth is fastest in the spring and early summer, slows in the late summer and fall, and virtually stops in the winter (Gebhart and Summerfelt 1978). The majority of fishes will have their highest densities shortly after the hatch occurs when larvae are concentrated, and natural mortality has not yet reduced numbers. Feeding competition is especially important during late spring through early summer when the bulk of fish are in their early life stages. During this time, they are more susceptible to starvation (May 1974). This is a critical stage in development, where larval fish have a short time period to initiate exogenous feeding before starving (Ehrlich 1974; Miller et al. 1988).

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT 4.6 Identification of Threatened, Endangered, and Other Protected Species Susceptible to Impingement and Entrainment at CWIS

[§ 122.21(r)( 4)(vi)J The Rule requires the permittee to document the presence of federally listed species and designated critical habitat in the action area (see 40 CFR 125.98[f]). For the purpose of defining listed species, the action area is defined as Shearon Harris Reservoir.

A desktop review of available resources was performed to develop a list of species with protected, endangered, or threatened status that might be susceptible to impingement and entrainment at the CWIS on Shearon Harris Reservoir. The USFWS's map-based search tool (Information for Planning and Consultation [IPaC]) was used to identify state or federally listed rare, threatened, or endangered (RTE) aquatic species or critical habitat designations within Shearon Harris Reservoir. Listed species spatial occurrence data from the North Carolina Natural Heritage Program was cross-referenced spatially with Shearon Harris Reservoir. Because the Shearon Harris CWIS is in a freshwater environment, marine and anadromous federally listed species and designated critical habitat under National Marine Fisheries Service jurisdiction were not considered.

State or federally listed rare, threatened, or endangered (RTE) aquatic species or critical habitat designations occurring with Shearon Harris Reservoir, are provided in Table 4-7. Federal species of concern and candidate species were omitted from the list (unless they were also state threatened or endangered), as there are no requirements to address those species under the Rule or Section 7 of the ESA. The following materials were reviewed to develop the species list in Table 4-7:

IPaC (https://ecos.fws.gov/ipac/) (USFWS 2019) for the search area shown on Figure 4-1, and North Carolina Department of Natural and Cultural Resources (NCDNCR) Natural Heritage Program Data explorer listed species element occurrence data (NCDNCR 2018).

Historical electrofishing results for Harris Reservoir are discussed in Section 4.2 of this report. No federally or state-listed species were collected during electrofishing surveys on Harris Reservoir from 2008 to 2016. The UFWS IPAC search indicated that the Cape Fear Shiner (Notropis mekistocholas) might be affected by activities in the search location (Shearon Harris Reservoir). The reservoir is outside of any critical habitat designation and is not included in any of the known or managed populations (USFWS 1987, 1988, 2017). The NCNHP element of occurrence spatial search did not have any records for federal or state listed species in the reservoir. The Cape Fear Shiner is not likely to occur in the reservoir.

4.10 Identification of Protective Measures and Stabilization Activities [§122.21(r)(4)(x)]

DEP has performed habitat improvements in Shearon Harris to increase angling success by recreational users at the DEP employee use area. The design of the cooling water intake structure (i.e., TSV less than 0.5 fps) are anticipated to minimize impingement and greatly reduce entrainment.

4.11 List of Fragile Species [§122.21(r)(4)(xi)]

In the Rule, the EPA identifies 14 species of fish as fragile or having post-impingement survival rates of less than 30 percent. Occurrence of fragile species in Harris Reservoir was evaluated using historical sampling data (Table 4-2 Fish Species and Community Composition). The environmental monitoring program for Harris Reservoir has documented Gizzard and Threadfin Shad in electrofishing surveys.

Gizzard Shad are listed by the EPA as a fragile species (Table 4-10). Threadfin Shad, which is not on the EPA's list of fragile species, is closely related to several fragile species (family Clupeidae) and is expected to have very low post-impingement survival. Both the Gizzard and Threadfin Shad are discussed in 43

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT Section 4.3.3 Selected Species Reviewed, and their seasonal and daily activities are summarized in Table 4-8. Because the CWIS has coarse-mesh screens with a TSV less than 0.5 fps, the facility is compliant with impingement mortality compliance option §125.94(c)(2). Impingement is anticipated to be negligible at this facility based on the low TSV; therefore, a discussion or assessment of potential fragile species is not warranted.

Each of these requirements is described in the following subsections.

5.1 Description of Cooling Water System Operation

[§ 122.21{r)(S )(i)]

HNP's circulating water system is a closed-loop system; that is, the water is recycled and reused in the steam turbine condensers. The purpose of the circulating water system is to supply cooling water to various plant components and systems. The heat transferred to the circulating water in the condenser is rejected to the atmosphere by the evaporation process in the cooling tower. Approximately 99 percent of the intake water is used for non-contact cooling and no water is used for contact cooling.

The closed cycle cooling system consists of a natural draft, hyperbolic cooling tower that provides a heat sink for the recirculating condenser cooling water and the normal service water systems. The normal service water is withdrawn from the closed-cycle cooling water system (cooling tower basin) and provides cooling water to various plant components and systems. During normal operation, one CTMU pump supplies all the necessary makeup water (37.44 MGD, design) for the closed-cycle cooling system in order to restore losses due to drift, evaporation, blowdown and internal consumption. Infrequently, in drought years, the CTMU pumps are also used to transfer water from the main reservoir to the auxiliary reservoir. Additionally, during periods of extreme cold weather, heated cooling water may be discharged to the auxiliary reservoir in order to ensure that ice does not build up at the emergency cooling water intake screening structure. The closed-cycle recirculating cooling system is generally in operation when the plant is in operation. Assuming a capacity factor of 90%, the plant would operate approximately an average of about 329 days per year. However, the circulating water pumps operated 45

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT continuously during the 2016-2018 period. The closed-cycle recirculating system has a blowdown that averages approximately four MGD per month.

The two ESW pumps are intended for emergency use only but are tested periodically to ensure reliable operation. Typically, one or the other EWS pump draws water from the auxiliary reservoir about four days per quarter and draws water from the main reservoir about 10 days per year. This amount totals approximately 786 million gallons per year. This water is conveyed through critical plant components and discharged back to the auxiliary reservoir by the ESW discharge canal.

Under normal operating conditions, the recirculating (internal) cooling water flow is 774.15 MGD. This total includes recirculating cooling water (702.15 MGD) and Normal service water (NSW, 72.0 MGD) flows apportioned as follows:

3 circulating water pumps@ 234.05 MGD each 1 NSW pump@ 72 MGD The total flow to the cooling tower is 846.15 MGD. The cooling tower makeup pump design flow is 74.9 MGD and this is considered to be the cooling water DIF.

5.1.1 Proportion of Design Flow Used in the Cooling Water System Historical water withdrawals from Harris Reservoir to support HNP operations from 2016 to 2018 are provided in Table 3-2 (Section 3.4). Based on the water balance diagram (Figure 3-1), approximately 99 percent of the intake flow is used for non-contact cooling purposes (i.e., cooling tower makeup water).

The remainder is used as service water for various plant uses such as fire protection water, boiler wash water, and demineralizer water. Table 5-1 provides the proportion of the 74.88 MGD DIF withdrawn from the Harris Reservoir from 2016 through 2018. Although the historical averages are not necessarily indicative of future withdrawals, only 31.4 percent of the DIF was withdrawn from the Harris Reservoir from 2016 to 2018.

5.2 Design and Engineering Calculations [§122.21(r}(S)(ii)]

Table 5-1 provides the estimated TSV under low and full pond water depths. The maximum withdrawal rate from the period of record (January 2016-December 2018) is 34.5 MGD (23,958 gpm) and occurred one time in July 2017. The engineering calculations ofTSV prepared by a qualified professional are provided in Appendix C.

Lake elevations are typically at or above 215 ft-msl. Based on the data reviewed to prepare this report, lake elevations below 213 ft-msl feet would be a rare if not exceptional event. At a lake elevation of approximately 212.8 ft-msl, the resultant through-screen velocity would be 0.50 fps.

~

HNP achieves substantial reductions in entrainment and impingement by means of flow reduction. The underlying assumption for entrainment is that entrainable organisms have limited or no motility and passively move with the water entering the power plant; therefore, reduction in flow results in a 47

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT commensurate reduction in entrainment'. This flow reduction is achieved through the use of dosed-cycle recirculating cooling system.

The design flow of the recirculating cooling system is 846.15 MGD. Assuming a 365 day per year operation this results in an annual flow of approximately 308,844.75 Million gallons per year or if the plant operated a once-through cooling system they would withdraw approximately this amount per year. The plant is designed to withdraw the following amount per year assuming no emergency withdrawal is needed:

Table 5-3. Design and Actual (2016-2018) Flow Data.

CTMU ESW Design Total Operation Total Actual Total (2016-2018)

Daily Volume 74.9 MGD design 37.44 MGD expected operation 23.5 MGD actual (2016-2018)

~-----.-

Annual Volume 27,338.SMG 13,665.6MG 8577.5 MG 786MG 28,124.5 MG 14,451.6 MG 9,363.5 MG Proportioning the recirculating water (hypothetical once-through) to the amount withdrawn by the closed-cycle system, a flow reduction of approximately 91% is realized. Since generally only one CTMU pump is in operation a more realistic flow reduction is approximately 95%. Actual operational data from January 2016-December 2018 shows a flow reduction of 97%. With either scenario, the flow reduction is certainly commensurate with those flows generally achieved by closed-cycle recirculating systems on a freshwater system.

7 This is the underlying assumption in EPA's calculation of entrainment reduction associated with closed-cycle cooling - see USE PA 2014.

Chosen Method(s) of Compliance with Impingement Mortality Standard [§122.21(r)(6)]

The information required to be submitted per 40 CFR § 122.21(rl(6) is as follows:

The owner or operator of the facility must identify the chosen compliance method for the entire facility; alternatively, the applicant must identify the chosen compliance method for each cooling water intake structure at its facility. The applicant must identify any intake structure for which a BTA determination for Impingement Mortality under 40 CFR 125.94 (c)(11) or (12) is requested.

The Rule at 40 CFR 125.94(c) gives existing facilities seven BTA options for achieving impingement mortality compliance. These are listed below. A facility needs to implement only one of these options.

1. Operate a closed-cycle recirculating system as defined at 40 CFR 125.92(c)(l) (this includes wet, dry or hybrid cooling towers, a system of impoundments that are not WOTUS, or any combination thereof);

2. Operate a cooling water intake structure that has a maximum design through-screen velocity of 0.5 fps or less;

3. Operate a cooling water intake structure that has a maximum actual through-screen velocity of 0.5 fps or less;

4. Operate an existing offshore velocity cap that is a minimum of 800 feet offshore and has bar screens or otherwise excludes marine mammals, sea turtles, and other large aquatic organisms; S. Operate a modified traveling screen system such as modified Ristroph screens with a fish handling and return system, dual flow screens with smooth mesh, or rotary screens with fish returns. Demonstrate that the technology is or will be optimized to minimize impingement mortality of all non-fragile species;

6.

Operate any combination of technologies, management practices, and operational measures that the Director determines is BTA for reducing impingement. As appropriate to the system of protective measures implemented, demonstrate the system of technologies has been optimized to minimize impingement mortality of all non-fragile species; and

7.

Achieve a 12-month performance standard of no more than 24 percent mortality including latent mortality for all non-fragile species.

Compliance options 1, 2, and 4 are essentially pre-approved technologies that require minimal additional monitoring after their installation and proper operation. Options 3, 5, and 6 require that more detailed information be submitted to the Director before they can be specified as the BTA to reduce impingement mortality. Options 5, 6, and 7 require demonstrations with field studies that the technologies have been optimized to minimize impingement mortality of non-fragile species.

In addition, the Rule provides two other impingement compliance BTA options for which the Director may consider little or no additional controls for impingement mortality (USEPA 2014a). These options apply under very specific circumstances.

49

316(b) Compliance Submittal Requirements SHEARON HARRIS NUCLEAR PLANT De minimis rate of impingement - if the rates of impingement at a facility are so low that additional impingement controls may not be justified (Section 125.94(cl(ll)); and Low Capacity utilization of generating units - if the annual average capacity utilization rate of a 24-month contiguous period is less than 8 percent (Section 125.94(c)(12)).

Harris Nuclear Plant meets the requirements of 40 CFR §125.94(c)(l) (BTA Option #1) based on data provided in Table 5-2. In addition, the cooling tower makeup pumps have a design and actual through-screen velocity of <0.5 fps and therefore compliant with the requirements of 40 CFR §125.94(c)(2) and (3) (BTA Options 2 and 3).

By meeting the CCRS criterion (BTA #1) the existing technologies in use at Harris Nuclear Plant are BTA for impingement mortality compliance. Furthermore, the cooling water makeup pumps have a design through-screen velocity that is lower than the 0.Sfps standard for impingement mortality compliance.

Entrainment Performance Studies [40 CFR § 122.21(r)(7)]

The information required to be submitted per 40 CFR § 122.21(r)(7), Entrainment performance studies, is as follows:

The owner or operator of an existing facility must submit any previously conducted studies or studies obtained from other facilities addressing technology efficacy, through-focility entrainment survival, and other entrainment studies. Any such submittals must include a description of each study, together with underlying data, and a summary of any conclusions or results. Any studies conducted at other locations must include an explanation as to why the data from other locations are relevant and representative of conditions at your facility. In the case of studies more than 10 years old, the applicant must explain why the data ore still relevant and representative of conditions at the facility and explain haw the data should be interpreted using the definition of entrainment at 40 CFR l25.92{h).

7.1 Site-Specific Studies [40 CFR §122.21(r)(7)(i)]

Harris utilizes a CCRS, therefore entrainment survival is not anticipated. Hence, no site-specific entrainment performance studies (i.e., studies evaluating biological efficacy of specific entrainment reducing technologies or through-facility entrainment survival) have been conducted at Harris.

7.2 Studies Conducted at Other Locations [40 CFR §122.21(r)(7)(ii)]

As of the date of this report, no entrainment performance studies conducted at other facilities have been determined relevant for documentation in this section.

Duke Energy Progress, LLC Harris Nuclear Plant National Pollutant Discharge Elimination System Permit Number NC0039586 Form 2C - Section 3.1 - Flows, Sources of Pollution, and Treatment Technologies

Duke Energy Progress, LLC Harris Nuclear Plant and Harris Energy & Environmental Center National Pollutant Discharge Elimination System Permit Number NC0039586 Attachment S Form 2C - Section 3.1 Flows, Sources of Pollution, and Treatment Technologies HARRIS NUCLEAR PLANT The Harris Nuclear Plant (HNP) consists of a l,0 16 MW generating unit and associated facilities.

The HNP systems include a Westinghouse pressurized water reactor, three re-circulating steam generators, a turbine generator, a one-pass condenser, an open re-circulating (cooling tower) cooling water system, and a lake to makeup water lost by evaporation. In a pressurized water reactor design, steam is produced in the secondary system steam generators using hot water from the reactor core. The primary system does not nonnally come into contact with any other part of the generating system, such as the steam cycle which includes the turbine and the condenser.

Outfall 006 - Combined Outfall to Harris Lake The HNP operates on an open re-circulating cooling system using a natural draft cooling tower and 4100 acre makeup water storage reservoir. All five major wastewater discharges at the HNP are combined in a 36-inch diameter common pipe which discharges to the Harris Lake 500 feet offshore at 40 feet below the surface (Discharge Serial No. 006 in this application.) The individual waste streams contributing to the common outfall pipe are: cooling tower blowdown, sanitary waste treatment plant effluent, metal cleaning wastes, low-volume wastes, and radwaste system. (These waste streams are enumerated in the present pennit as Discharge Serial Numbers 001. 002, 003, 004, and 005, respectively.) Toxicity testing has been conducted on the combined outfall line since February 1990. Each of the waste streams, as well as miscellaneous discharge points, are described in this narrative. Also included is a list of chemicals which are expected to be in waste streams from the HNP (Attachment 6).

Outfall 001-HNP Cooling Tower Blowdown discharge to Outfall 006 The cooling tower provides the condenser with a supply of water for removing the heat rejected by the condensation of steam. (The circulating water temperature rise across the condenser is 2s*F.) This heat is dissipated primarily by evaporation as the water falls through the tower.

This evaporation is essentially pure water vapor, with the dissolved and suspended solids remaining to concentrate.

To prevent the solids from causing scale and corrosion problems, some of the concentrated cooling water is discharged from the cooling tower basin, i.e., blowdown.

During plant operation, the cooling tower basin continuously discharges for optimum perfonnance.

Blowdown currently averages approximately 6 MGD.

Makeup water for cooling tower evaporative losses and cooling tower blowdown is provided from the main reservoir. The cooling tower also serves as a partial source of service water, which is used for non-contact cooling of auxiliary equipment throughout the plant. The cooling tower is infrequently drained

Duke Energy Progress, LLC Harris Nuclear Plant and Harris Energy & Environmental Center National Pollutant Discharge Elimination System Permit Number NC0039586 for maintenance. The normal operating procedure includes draining the residual water to the lake via Discharge Serial No. 006.

Occasionally, the condensers are drained for maintenance and repairs. When the condensers are drained, it is necessary to route the residual water (approximately 60,000 gallons per condenser per event) to area storm drains which discharge to the lake. This water is monitored prior to discharge for appropriate parameters required for cooling tower blowdown in accordance with the NPDES permit. Presently, condenser draining events are reported with relevant monitoring data to DWQ on attachments to monthly Discharge Monitoring Reports.

Outfall 002 - HNP Sewage Treatment Facility discharge to Outfall 006 The HNP is served by a 0.065 MGD firm capacity sewage treatment facility comprised of:

a) a 0.015 MGD extended aeration sewage treatment facility (consisting of an equalization basin, aeration basin, sludge holding tanks, raw sewage holding tank, clarifiers, and chlorine contact tanks); This unit is current not being operated. and b) a 0.050 MGD recirculating packed bed filter system consisting of four T-Max settling units, six AX-Max treatment units, two AdvanTex polishing units, ultraviolet disinfection, and an effluent pump station serving the combined sanitary treatment units to discharge to Outfall 006.

Currently, treatment system residuals are land applied off site by a contract disposal firm (Granville Farms, Inc., Permit No. WQ0000838).

In addition to sanitary waste, HV AC condensate is discharged to the sewage treatment facility. Because the HNP sewage treatment facility receives industrial type waste as well as domestic type waste, the land application of the mixed sludge meets the exemption conditions stipulated at 40 CFR Part 503.6.

Outfall 003 - HNP Metal Cleaning Wastes discharge to Outfall 006 Infrequently, cleaning of heat exchanger equipment by chemical solutions may be necessary.

Cleaning solutions would be routed to the waste neutralization basin for pH adjustment (or other chemical neutralization) prior to discharge to the settling basin where further treatment by sedimentation occurs.

To date, the only metal cleaning which has been conducted was a preoperational flush. If a new system is added in the future or if an existing system is changed out, flushing could be necessary again. Also, metal cleaning may be needed in the future for plant systems (e.g., steam generators, auxiliary boilers, piping, etc.). Chemical solutions used may include phosphates, organic cleaners, citric acid, or oxalic acid.

2

Duke Energy Progress, LLC Harris Nuclear Plant and Harris Energy & Environmental Center National Pollutant Discharge Elimination System Permit Number NC0039586 Outfall 004 - HNP Low-Volume Wastes discharge to Outfall 006 In the operation of the HNP, there are many processes which result in intennittent low volumes of various waste streams. Low-volume waste is treated by neutralization (for pH adjustment),

sedimentation, and separation. These wastes may be treated in the oily waste separator and/or neutralization basin as needed prior to routing to the sedimentation basin, which ultimately discharges to the common outfall line. Periodically as a maintenance practice this basin may be physically cleaned using chlorine, a bisulfate is added after cleaning to remove the chlorine before discharge. Chemicals present in these systems may include corrosion products {such as copper and iron) corrosion inhibitors {such as nitrites, molybdates, ammonia, hydrazine, carbohydrazide, and ethanolamine), acids and bases from water treatment processes, and wastewater from ion exchange processes and ammonium bisulfite from dechlorination. Low-volume waste flow from the settling basin averages approximately 0.2 MGD. The various low-volume waste sources are described below:

a)

Water treatment system wastes from processing of demineralized water and potable water.

(The water treatment system includes coagulation, filtration, disinfection, and ion exchange. Wastes from treatment include filter backwash and demineratizer regeneration wastes.)

b)

Non-radioactive oily waste, floor drains, and chemical tank containment drains.

{Turbine building wastes which could contain oil are routed to the oily waste separator for treatment prior to routing to the neutralization basin. Used oil is collected by a contractor for reclamation.)

c)

Steam generator and auxiliary boiler draining following wet layup d)

Non-radioactive secondary waste from condensate polishers e)

Miscellaneous drains/leaks from condenser, steam generator, and secondary components t)

Auxiliary boiler system blowdown g)

Miscellaneous waste streams not otherwise identified elsewhere in this application.

Outfall 005 - HNP Radwastc Treatment System discharge to Outfall 006 The radwaste system is designed to collect, store, process, and release any radioactive or potentially radioactive liquids associated with operation of the nuclear power plant. The waste streams are collected in tanks and sampled for conventional pollutants and radioactivity. The 3

Duke Energy Progress, LLC Harris Nuclear Plant and Harris Energy & Environmental Center National Pollutant Discharge Elimination System Permit Number NC0039586 specific batch treatment is selected based on these analytical results. This allows for selection of the proper treatment processes for each individual batch. Most radwaste streams are treated by the Modular Fluidized Transfer Demineralization System (MFTDS) that uses filtration and ion exchange in a manner that minimizes the production of solid wastes. Boric acid is recycled. The secondary waste system (SWS) is for treating radioactively-contaminated water from the secondary steam cycle system; however, since that system is not normally contaminated, those flows are routed to the normal low-volume waste treatment system after radiological monitoring.

After treatment, the radwaste flows are stored in one of four tanks: the secondary waste sample tank, the treated laundry and hot shower tank, the waste monitor tank, or the waste evaporator condensate tank. After monitoring to verify adequate treatment, the tanks are discharged to the common outfall line.

The cooling tower bypass line provides a flow of lake water for radwaste releases, as regulated by the NRC.

Other BNP Discharges I.

Storm Drains Runoff from parking lots, outside storage areas, roof drains, and other areas on the plant site are collected in storm drains and ultimately routed to release points which discharge to Harris Lake. Flow contributed from those areas is estimated at 8.8 million gallons per month, based on average rainfall of 43 inches per year and a runoff assumption factor of 0.7.

In addition to stormwater, a few miscellaneous sources of water are also intermittently routed to the storm drains. These sources that have a minor contribution to overall storm drain flows are as follows:

a.

b.

Upflow Filter Clearwell System The upflow filter clearwell system has been abandoned in place and no longer has any drains which might discharge to Harris Lake.

Heat exchanger on the demineralizer feedwater It is necessary to heat the source water to the demineralized water treatment system to achieve optimum degassification. To accomplish this, steam is used to heat the feedwater. The condensed steam is discharged to the storm drains that flow to Harris Lake at approximately 5 - l O gallons per minute. This steam could contain trace amounts of hydrazine and ammonia used for chemistry control in the auxiliary boiler steam system. Due to the low flow rate and the long retention 4

Duke Energy Progress, LLC Harris Nuclear Plant and Harris Energy & Environmental Center National Pollutant Discharge Elimination System Permit Number NC0039586 time, the temperature of the condensed steam should be at ambient temperature upon reaching the lake.

c.

Condenser water box drains

d.

Prior to condenser maintenance or repairs 1t 1s sometimes (approximately twice/year) necessary to drain circulating water to the storm drains (approximately 60,000 gallons per condenser per event) that discharge to Harris Lake. This water is monitored for selected cooling tower blowdown parameters.

Filtered water storage and Demin water Storage Tanks Water is treated using a micro-filtration unit for turbidity control and then stored in a tank prior to subsequent filtration (nano-filtration unit) and disinfection.

Occasionally, some water from these tanks may be drained to the stonn drains that discharge to Harris Lake. This water may contain trace amounts of chlorine.

e.

Fire protection system

f.

g.

Approximately 5000 gallons of lake water used for annual testing of the fire protection system is routed to most of the stonn drains that discharge to Harris Lake. In the event of a fire, additional water could be discharged to stonn drains.

Condenser hotwell During outages (approximately once per 18 months) it is necessary to drain the condenser hotwell for condenser maintenance and inspection. Approximately 70,000 gallons of this water resulting from condensed steam is drained to stonn drains that discharge to Harris Lake.

It may contain trace amounts of ethanolamine, JOO ppb or less of boron, and 100 ppb or less ammonia.

Condensate storage tank Infrequently it is necessary to drain the condensate storage tank for maintenance.

Approximately 400,000 gallons per event is drained to stonn drains that discharge to Harris Lake. It may contain 200 ppb or less boron, 1000 ppb or less ammonia, and trace hydrazine.

Duke Energy Progress, LLC Harris Nuclear Plant and Harris Energy & Environmental Center National Pollutant Discharge Elimination System Permit Number NC0039586 Service water system strainers Infrequently, when service water strainers located at the makeup pumps from the cooling tower basin are backwashed to remove biofouling organisms or debris, a small volume of service water overflows the basin and runs to the adjacent stonn drain that discharge to Harris Lake.

Maintenance Activities During maintenance activities at the facility it may become necessary to drain all or some portion thereof of the following plant systems; nonnal service water, emergency service water, circulating water, potable water, and demineralized water. Maintenance activities at the facility may also require the hydrostatic flushing of system piping with discharge to the stonn drain system. In addition, the facility may find it necessary to wash equipment with eemiAereli:zee water and discharge to the stonn drains Emergency Service Water System This system primarily provides non-contact cooling water for nuclear safety-related equipment systems and during emergency conditions. The emergency service water system discharges to the auxiliary reservoir which is used as the plant's heat sink during emergency conditions, a feature required by Nuclear Regulatory Commission regulations to provide a reliable supply of cooling water. Under normal operating conditions, the auxiliary and the main reservoirs are isolated from each other; however, the reservoirs may be connected as necessary. In addition to emergency situations, this system is used periodically for to raise auxiliary reservoir basin level, system testing purposes or for containment cooling as needed. This water may contain traces of chemicals identified for the cooling tower blowdown.

Duke Energy Progress, LLC Harris Nuclear Plant and Harris Energy & Environmental Center National Pollutant Discharge Elimination System Permit Number NC0039586 HARRIS ENERGY & ENVIRONMENT AL CENTER The Harris Energy & Environmental Center (HE&EC) includes facilities that provide support services (laboratories and training classrooms) for the HNP and other CP&L operations. The sources of wastewater at the HE&EC are domestic waste. conventional laboratory waste, cooling tower blowdown, and potentially radioactive liquid waste from the radiochemistry and metallurgy laboratories. Additionally, floor drains from several shops and storage buildings are routed to the wastewater treatment facility.

All waste streams, with the exception of the radiological wastewater, receive treatment in the 0.020 MOD wastewater facility.

Components of the treatment facility include a bar screen, submersible pump station as an influent pump station, three treatment ponds, sand filtration, chlorination and dechlorination, as well as the various lift stations for the HE&EC's various buildings. The pond portion of the treatment facility consists of an aerated pond with a minimum retention time of IO days followed by a stabilization pond, also with a minimum retention time of IO days. The third pond is a polishing pond with a minimum 2-day retention time. Effluent from the treatment facility is discharged via the effluent discharge pipe into Harris Lake.

If necessary, sludge from the treatment facility will be removed and land applied by a contractor (a contractor for sludge disposal will be chosen when needed). Because the treatment facility receives industrial type waste as well as domestic type waste, the land application of the mixed sludge meets the exemption conditions stipulated as 40 CFR 503.6 Domestic Waste The maximum domestic waste flow from the HE&EC sanitary facilities is approximately 0.014 MOD. In addition to the approximately 200 permanent employees on the site, the HE&EC, serving as a company training facility and as a visitors' center for the nearby Harris Nuclear Plant, accommodates a fluctuating population (ranging from Oto 450 additional people per day).

Wastewater from the HNP may also be conveyed on private plant roads, to the HE&EC for treatment during times where sanitary flows generated onsite exceed the capacity of the HNP sewage treatment plant.

Laboratory Waste Laboratory waste flow, consisting primarily of rinse water from the chemical, metallurgical, and biological laboratories, is approximately 0.00 I MOD. HE&EC personnel are educated in the proper disposal of laboratory wastes and are encouraged to minimize the use of laboratory drains for chemical disposal. Most laboratory chemical wastes and oily wastes are drummed for off-site disposal.
