Subject: Final NPDES Permit Renewal
Permit NCO039586
Shearon Harris Nuclear Plant
Wake County
Class II Facility
Dear Ms. Hamilton:
Division personnel have reviewed and approved your renewal application for the subject permit.
Accordingly, we are forwarding the attached NPDES permit. This permit is issued 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 dated October 15, 2007
(or as subsequently amended).
After evaluation of your comments on the draft permit the Division offers the following
responses:
• pH limits at outfalls 001, 004, and 005 — the Division agrees to remove the pH limits for
the low volume waste outfalls 004 and 005. These outfalls are a relatively small volume
and are combined with the much larger flow from outfall 001 and other internal outfalls.
The pH limits for outfalls 001 and 003 will remain in the permit.
• Schedule of compliance for copper and zinc limits at outfall 006 — The final limits and
effective day were maintained as in the draft permit. The Schedule of Compliance was
modified to include language pertaining to additional studies that may be included in the
Corrective Action Plan. Upon completion of studies and approval by the Division you
may request a permit modification to implement alternative limits.
• Outfall 002 Total Residual Chlorine — a footnote was added indicating that monitoring is
only applicable if chlorine is added.
• Auxiliary Reservoir Special Condition — this condition was inadvertently omitted from
the draft permit. It is now included as Special Condition A. (20).
• Special condition A. (15) was corrected to refer to the Shearon Harris Nuclear Plant.
• Supplement to Permit Cover Sheet — the holding tanks and comminutor were eliminated
from the description of the treatment system for outfall 002

Notes:
1. Effluent prior to mixing with any other waste stream.
2. Discharge of blowdown from the cooling system shall be limited to the minimum discharge of recirculating water
necessary for the purpose of discharging materials contained in the water, the further built-up of which would cause
concentrations in amounts exceeding limitations established by best engineering practices. The permittee may discharge
cooling water to the auxiliary reservoir in compliance with condition A. (20) of this permit.
3. Neither free available chlorine nor total residual chlorine may be discharged from any unit for more than two hours in any
one day and not more than one unit in any plant may discharge free available or total residual chlorine at any one time
unless the utility can demonstrate to the Director that the units in question cannot operate at or below this level of
chlorination. The permittee shall record and report times of release as part of the monthly monitor report. Free available
chlorine shall be a daily average and daily maximum.
4. Samples shall be multiple grabs at the tower'which shall consists of grab samples collected at the approximate beginning
of the total residual chlorine discharge and once every 15 minutes thereafter until the end of the total residual chlorine
discharge. For the purpose of this permit, daily average (as it relates to the chlorination period) shall mean the average
over any total residual chlorine discharge period.
5. These limitations and monitoring requirements apply only if these materials are added for cooling tower maintenance by
the permittee. There shall be no discharge of detectable amounts of the 126 priority pollutants (40 CFR 423 Appendix A)
contained in chemicals added for cooling tower maintenance except for Total Chromium and Total Zinc. Compliance with
the limitations for the 126 pollutants may be determined by engineering calculations which demonstrate that the regulated
pollutants are not detectable in the discharge by the analytical methods in 40 CFR 136.
6. By December 21, 2016, begin submitting Discharge Monitoring Reports electronically using NC DWR's eDMR
application system. See Special Condition A (19).

practicable, the stormwater management plan shall document the feasibility of diverting the stormwater runoff
away from areas of potential contamination.
(2) A schedule to provide secondary containment for bulk storage of liquid materials, storage of Section 313 of
Title III of the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals, or storage
of hazardous materials to prevent leaks and spills from contaminating stormwater runoff. If the secondary
containment devices are connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be secured with a locking
mechanism] and any stormwater that accumulates in the containment area shall be at a minimum visually
observed prior to release of the accumulated stormwater. Accumulated stormwater shall be released if found
to be uncontaminated. Records documenting the individual making the observation, the description of the
accumulated stormwater and the date and time of the release shall be kept for a period of five years.
(3) A narrative description of Best Management Practices (BMPs) to be considered such as, but not limited to, oil
and grease separation, debris control, vegetative filter strips, infiltration and stormwater detention or retention,
where necessary. The need for structural BMPs shall be based on the assessment of potential of sources
contributing significant quantities of pollutants to stormwater discharges and data collected through monitoring
of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to be taken to limit or prevent
erosion associated with the stormwater systems.
C. Spill Prevention and Response Plan: The Spill Prevention and Response Plan shall incorporate a risk assessment of
potential pollutant sources based on a materials inventory of the facility. Facility personnel (or team) responsible for
implementing the plan shall be identified in the plan. A responsible person shall be on-site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or exposure of materials associated
with the facility operations.

permit. Within 30 days of suc h notice, the permittee shall submit a time schedule to the Director for modifying the Plan
to meet minimum requiremen s. The permittee shall provide certification in writing (in accordance with Part VI, Section
B.11.) to the Director that the changes have been made.
h. Facility Inspections: Inspecti ns of the facility and all stormwater systems shall occur at.a minimum on a semiannual
schedule, once in the fall (September - November) and once during the spring (April - June). The inspection and any
subsequent maintenance activities performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a E arrative description of the facility's stormwater control systems, plant equipment and
systems. Records of these inspections shall be incorporated into the Stormwater Pollution Prevention Plan.
Visual monitoring as required in Part I, Section A(8) Stormwater Monitoring Requirements/Qualitative Monitoring shall
be performed in addition to facility inspections.
Implementation: Implements ion of the Plan shall include documentation of all monitoring, measurements, inspections,
maintenance activities and tr, ining provided to employees, including the log of the sampling data. -Activities taken to
implement BMPs associated with the industrial activities, including vehicle maintenance activities, must also be
recorded. All required docun entation shall be kept on-site fora period of five years and made available to the Director
or his authorized representative immediately upon request.
3.
Minimum monitoring and reporting requirements are as follows unless otherwise approved in writing by the Director:
a. If a facility has multiple disc arge locations with substantially identical stormwater discharges that are required to be
sampled, the permittee may petition the Director for representative outfall status. If it is established that the stormwater
discharges are substantially identical and the permittee is granted representative outfall status, then sampling
requirements may be performed at a reduced number of outfalls.
b. Qualitative monitoring for c 'lor, odor, solids, foam, outfall staining, visible sheens and dry weather flow shall be
performed at all stormwater discharge outfall locations. All qualitative monitoring shall be documented and records
maintained with the Stormwa 'er Pollution Prevention Plan. The initial qualitative monitoring event shall be performed
simultaneously with the first nalytical monitoring event and documentation of only this initial qualitative monitoring
event shall be submitted alonj with the required analytical monitoring submittal.
C. If the stormwater runoff is co#trolled by a detention pond, the following sampling requirements shall apply:
(1) If the detention pond detains the runoff generated by one inch of rainfall for 24 hours, visual observations for
color, foam, outfall taining, visible sheens and dry weather flow are required, but analytical sampling shall
not be required.
Page 14 of 16

NPDES Permit NCO039586
(2) If the detention pond discharges only in response to a storm event exceeding a 25 -year, 24-hour storm, the
pond shall be considered a non -discharging stormwater control system and not subject to NPDES requirements,
unless the discharge causes a violation of water quality standards.
d. Samples analyzed in accordance with the terms of this permit shall be submitted on forms approved by the Director no
later than January 31 for the previous year in which sampling was required to be performed.
e. Analytical results from sampling during the final year of the permit term shall be submitted with the permit renewal

Subject: RE: Duke energy Comments on draft permit NCO039586
We had this question come up in another permitting action and took the position that internal monitoring of pH would
not be necessary, unless there is reason to believe that the characteristics of the wastestreams being combined could
result in higher pollutant discharge — for example, if a highly acidic waste is combined with another waste that could
lead to dissolution of heavy metals that are not subsequently removed from the combined stream prior to discharge. I
think combining the wastes in this permit, without internal monitoring for pH, would be acceptable. I wasn't able to
track down any email relating to the previous permitting action dealing with this issue, but you may want to reach out to
Sean or Scott for their feedback.

In short, Duke wants no pH limits applied to the internal outfall for low volume waste since this waste stream mixes
with cooling tower blowdown. They only want the pH limit to apply after mixing.
It is my understanding that since the LVW mixes with CTB and not with just once through cooling water, the pH limits
would still apply at the internal outfall.
What is your recommendation?

Permitting gee.tion
In accordance with your letter dated July 13, 2016, Duke Energy staff have reviewed the
proposed draft permit and the accompanying Fact Sheet and offer the following comments in
response to your bulleted draft permit proposals:
Draft Permit Proposal:
• pH limits of 6 to 9 S.U. were added to outfalls 001, 004, and 005 as required per 40 CFR
423.12 (b) (1).
Comments:
Duke Energy requests that the Division remove pH monitoring and limits from outfalls 001, 003,
004, and 005, all of which are internal outfalls that discharge to outfall 006. (In addition to the
three outfalls in this bullet, pH limits were also added to outfall 003.) Limitations for pH are more
appropriate for outfalls discharging to surface waters, for the following reasons:
1. 40 CFR. 423.12(b)(1) requires pH limits only on outfalls discharging to surface waters
The requirements of 40 CFR 423.12(b)(1) read as follows:
(1) The pH of all discharges, except once through cooling water, shall be within the range of
6.0-9.0.
The .definition of "discharge" in 40 CFR 122 reads as follows:
Discharge when used without qualification means the "discharge of a pollutant."
Page 1

t �

Discharge of a pollutant means:
(a) Any addition of any `pollutant" or combination of pollutants to "waters of the United States"
from any `point source, "or
(b) Any addition of any pollutant or combination of pollutants to the waters of the "contiguous
zone" or the ocean from any point source other than a vessel or other floating craft which is
being used as a means of transportation.
The phrasing indicated in 40 CFR 423.12(b)(1) means a discharge to waters of the United
States and thus would be appropriate for this permit for Outfall 006. The remaining BPT limits in
this section refer to a pollutant being discharged "from" or "in" a specific source and thus are
appropriately applied to internal outfalls.
2. EPA guidance recommends against use of pH limits on internal outfalls
The pH limits of 40 CFR 423.12(b)(1) were proposed and adopted in the original 1974 Effluent
Limitations Guidelines for the Steam Electric Industry (ELG) as best practical control technology
(BPT). In the 1980 Development Document for the proposed revisions to the ELG, EPA
provided a discussion of the application of the effluent limitations guidelines presented in the
1974 Development Document that accompanied the rulemaking. In this discussion, EPA
specifically stated "In -plant dilution is permitted to achieve pH limitations."' This interpretation is
also explained in several guidance letters from EPA included in Attachment A and this approach
has been used in recent permits issued by EPA. A summary of these letters and their
application is as follows:
March 10, 1976, Letter from USEPA to Philadelphia Electric Company states:
`:. waste streams could be combined with cooling water for the sole purpose of pH
neutralization, as long as the final discharge was in the range of 6-9."
October 18, 1985, Letter from USEPA to New York State Department of Environmental
Conservation states:
"...the pH limitation per 423 applies at the "end of pipe" discharge to surface waters when
the wastewater discharges contains low volume waste that is commingled with once -through
cooling water."
February 24, 1986, Letter from National Expert Steam/Electric Region IV (Charles Kaplan) to
Environmental Engineer Region 2 (Dit Fai Chung) states:.
"... pH limitations for the comingled stream are applicable at the combined discharge point
to water of the U.S."
March 21, 1986, Letter from USEPA to Regional Permit Chiefs, State Directors, states:
"the pH limitations for the low volume waste (6.0 — 9.0 range) may be applied after
combination of once -through cooling, provided that monitoring is prior to discharge to
Waters of the United States."
11980 Dev. Doc. at 470
Page 2

t ,

USEPA, New England - Region I Fact Sheet Draft NPDES Permit for Mirant Canal, LLC, states:
"Monitoring for pH at the internal outfalls 010, 011, and 012 is not necessary as explained in
EPA's March 21, 1986, Memorandum from Charles Kaplan, EPA's National Steam
Electric/Water Expert, to Regional Permit Branch Chiefs and State Directors. Using dilution
to accomplish the neutralization of pH is preferable to adding chemicals."
3. Recent decisions by EPA in the ELG Rule demonstrate that pH monitoring on internal
outfalls is unnecessary
In the recently finalized revisions to the ELG, much emphasis was placed on demonstrating
compliance prior to the mixing of waste streams. EPA proposed that dischargers
demonstrate compliance with the proposed effluent limitations and standards applicable to a
particular waste stream prior to mixing the treated waste stream with other waste streams,
which could require internal outfalls; however, EPA explicitly stated the provision would
apply to all effluent limits "except pH."2 The exemption of pH provides justification that EPA's
policy of not setting internal limits for pH still applies. EPA opted to not finalize the rule
requiring internal outfalls but chose to recommend conducting a combined waste stream
formula (CWF) or building block approach to determine whether internal outfalls are
necessary or apply appropriate limits at the final outfall. The purpose of this action was to
ensure the pollutant loading (i.e. mass) is reduced and not merely "masked" through dilution
when concentration limits are applied. However, pH is not a mass based parameter and is
not associated with pollutant loading. Furthermore, Section 14 of the Final Technical
Development Document for the revisions to the ELG provides illustrations of compliance
points under different pre- and post -rule scenarios. In all scenarios, BPT limits, which
include pH, are depicted as applying at the final outfall. Even though only one of the waste
streams proposed for revision and none of the waste streams revised in the final rule apply
to HNP, the fact that EPA specifically stated effluent limits at internal outfalls would not
include pH supports that limits for pH should be applied only at the final outfall.
4. Limits on pH at internal outfalls are not necessary to protect the environment
Furthermore, there is no environmental justification for establishing pH limits at the internal
outfalls. As stated above, pH is not a parameter associated with pollutant loadings, but
rather is a scale for expressing the acidity or alkalinity of a solution. The preferred treatment
is neutralization with a buffer solution. By utilizing mixing with other waste streams,
neutralization can be accomplished without chemical addition or at least minimizing
chemical addition at the final outfall. As stated in the documents discussed above (February
24, 1986, Letter and USEPA Region 1 Fact Sheet for the Mirant Canal, LLC, NPDES
Permit), using dilution to accomplish the neutralization of pH is preferable to adding
chemicals.
Draft Permit Proposal.
• Effluent and Monitoring requirements for outfall 002 were modified to reflect the
expansion of the wastewater treatment system: Special Condition A. (18) was added to
the permit to allow for the transfer of wastewater between the two domestic WWTPs.
Comments:
Duke Energy agrees with this approach.
2 78 Fed. Reg. 34523 (7 June 2013)
Page 3

If the Division includes the Total Copper and Total Zinc limits, the following language should be
added to Part I (A)(9) — Schedule of Compliance:
"The Corrective Action Plan may include submission of additional effluent and receiving
water data, mixing zone analyses, and/or site specific studies to indicate that alternative
effluent limitations for total copper and total zinc are appropriate to achieve the dissolved
water quality criteria. The adopted water quality standards define the criteria as the
hardness based criterion times a Water Effect Ratio (WER) and also indicate alternative
site specific standards can be developed. Methods for conducting site specific studies
including development of WER will be reviewed with the Division.
"Upon review and approval of supplemental data, analyses, and/or site-specific studies,
the Division agrees to base development of effluent limitations for total copper and total
zinc based on the results of these studies and modify this NPDES permit accordingly."
Draft Permit Proposal.
• As a result of the RPA, monitoring for total nickel, total iron and total manganese were
removed from the monitoring requirements for outfall 001.
Comments:
Duke Energy agrees with this approach.
Draft Permit Proposal:
• Flow monitoring was added to outfall 006. Flow is a monitoring requirement for all
discharges per 15A NCAC 0213.0505.
Comments:
Duke Energy agrees with this approach and recommends the flow units for monitoring be
specified as Million Gallons per Day (MGD).
Draft Permit Proposal:
• Special Condition A. (17) was added to the permit regarding the submittal of all the required
information under 40 CFR 125.95 with the next permit application.
Comments:
Duke Energy agrees with this approach.
Draft Permit Proposal:
• The stormwater requirements included in Special Condition A. (20) will expire when the
Division of Energy, Minerals and Land Resources issues the individual stormwater permit for
this facility.
Comments:
Duke Energy agrees with this approach.
Draft Permit Proposal:
• A special condition was added to your permit including requirements for electronic reporting.
Proposed federal regulations require electronic submittal of all discharge monitoring reports
(DMRs) and specify that, if a state does not establish a system to receive such submittals,
then permittees must submit DMRs electronically to the Environmental Protection Agency
(EPA). The Division anticipates that these regulations will be adopted and is beginning

implementation. The requirement to begin reporting discharge monitoring data electronically
using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application
has been added to your NPDES permit. [See Special Condition A. (19)] For, information on
eDMR, registering for eDMR and obtaining an eDMR user account, please visit the following
web page: http://portal.ncdenr.org/web/wq/admin/boq/ipu/edmr. ,
For information on EPA's proposed NPDES Electronic Reporting Rule, please visit the
following web site: hftp://www2.epa.gov/compliance/proposed-npdes-electronic-reporting-
rule.
Comments:
Duke Energy agrees with this approach.
Draft Permit Proposal:
• The following special conditions were added to the permit to be consistent with other Duke
Energy permits: A. (10) Biocides, A. (11) Chemical Cleaning Wastes, A. (12) Combined
Waste Streams, A. (13) Federal Insecticide, Fungicide and Rodenticide Act, A. (14) PCB
Compounds, A. (15) Radioactive Material, and A. (16) Toxicity Reopener.
Comments:
Duke Energy agrees with this approach.
Our review also identified several other items for which we would like to offer the following
comments:
1. Relative to Total Residual Chlorine monitoring requirements for Outfall 002, this sanitary
waste treatment system functions predominately with a ultraviolet (UV) disinfection system.
The sodium hypochlorite system is rarely used and is maintained for backup purposes.
Duke Energy requests that a footnote for Total Residual Chlorine in Outfall 002 be added to
read:
"Total Residual Chlorine is only required to be monitored and reported if chlorine is added to
the sanitary treatment system for disinfection purposes."
2. A special condition in the previous NPDES permit (Part II, Special Condition No. 2)
regarding the Auxiliary Reservoir was removed from the proposed draft permit. This
condition should be reinstated in the final permit:
"In order to ensure that the auxiliary reservoir is available for its designated use at all times,
the permittee may circulate heated water through the auxiliary reservoir to prevent ice
formation at any time that the surface water temperature is below 35°F provided that the
surface water temperature in the auxiliary reservoir is not raised more than 5°F above
ambient temperature and in no case is raised to more than 40°F. Emergency Service Water
may be discharged to the auxiliary reservoir as required for operation of nuclear safety
systems and testing."
3. Special Condition A. (15) references McGuire Nuclear Station and should be corrected to
read "Harris Nuclear Plant."
Page 6

4. On the "Supplement to Permit Cover Sheet," the description of the 0.02 MGD wastewater
treatment facility should be revised to remove the following components:
a. Holding tanks; and
b. Comminutor.
These pieces of equipment are no longer in service and are not necessary to meet the
performance requirements associated with Outfall 007.
5. On Page 2 of the "Fact Sheet for NPDES Permit Development," Outfall Description for
Outfall 005, the following description clarification is suggested:
Radwaste treatment system. Treatment for potential radioactive liquids. The waste streams
are collected in tanks and sampled prior to selecting treatment. Radwaste is treated by a
Modular Fluidized Transfer Demineralization System MFTDS . Radiological treatment
10 processes and components are modified as necessary to achieve desired treatment in
compliance with Nuclear Regulatory Commission regulations. If not radioactive, the wastes
are routed to the low volume waste treatment system.
6. On Page 2 of the "Fact Sheet for NPDES Permit Development," Outfall Description for
Outfall 007, the reference to "radiological wastes from cleaning lab glassware" should be
removed' since cleaning of such radiological glassware has been discontinued at the Harris
U�Energy & Environmental Center.
If you have any questions or wish to discuss this matter further, please do not hesitate to
contact Mr. Bob Wilson, Harris Nuclear Plant Environmental Coordinator, at 919-362-2444.

to ash pond effluents indicate effective removal of certain trace
metals, but more studies are necessary to confirm these results.
(b) NSPS
For the same reasons that EPA is not proposing any requirements beyond
EPT for existing sources, EPA is proposing to withdraw the current
HSPS requirement of 20 times recycle and substitute the basic EPT
requirement in its place. Unlike dry fly ash handling systems for new
sources (which are no more costly than other fly as handling systems)
a recycle system for bottom ash is substantially more expensive than
other bottom ash handling systems.
(c) PSES and PSIS
The proposed PSES and PSNS do not restrict the discharge of any
pollutants from this wastewater source. The costs of controlling
priority inorganic pollutants and the low levels of pollutants
detected do not warrant the imposition of effluent standards for this
waste stream at this time.
E. metal Cleaning Wastes
This document supercedes all previous memoranda on effluent I'm' -
tations guidelines regarding the definition of metal cleaning wastes.
Metal cleaning wastes include boiler tube cleaning waste, air
preheater wash water and fireside wash water, with or without the use
of chemicals during the cleaning process.
The limitations for iron and copper of 1 mg/1 will not be changed.
For those cases where chelating or complexing agents are used in the
cleaning process, the treatment technology scheme may meed to be
altered. Lime treatment of these chelated wastes, together with air
preheater and fireside wash water (at the proper ratio), will result
in the achievement of the 1.0 mg/1 limitation. An alternate
precipitation scheme using sulfide will also achieve the 1.0 mg/1
limit.
F. Low -Volume Wastes
The best practicable technology currently available is found to be
adequate for control and is being defined as best available technology
economically achievable. Boiler blowdown, which is currently
considered as a separate waste category, is required to be treated for
iron and copper. In reexamination of the waste characteristics
information, boiler blowdown is now redefined as low-volume waste and,
therefore, is no longer subject to the iron and copper limitations.
ApRlication of Effluent Limitations Guidelines and Standards
A discussion of the application of the effluent limitations guidelines
was presented in the 1974 Development Document (1). Certain aspects
relating to the implementation of the original guidelines and
ME

i
recommended revisions are discussed below. In -plant dilution is
permitted to achieve pH limitations. Consolidation of waste streams
to a centralized treatment system is permitted and encouraged. The
quantity of pollutant permitted to be discharged, however, is not
always equal to the total flow times the effluent limitations. #
guidelines. It would equal the effluent limitations guidelines times
total flow only if all the raw waste streams contributing to the
central treatment system have waste characteristics which exceed the
guidelines.. -For cases where the dilution ratio would be so great that
the analytical method is not accurate enough to distinguish the
difference (such as low volume wastes containing oil and grease #
exceeding 15 mg/l are discharged to ash ponds), monitoring at the
point prior to mixing (or dilution) would be required. The same
analogy can be used for any stream and any pollutant.

This is to confirm our recent conversation regarding
effluent limitations guidelines for the steam electric power
industry (40 CFR Part 423),
In mfr letter of June 22� 2984 to tis. Ursula Basch of
your office, I summarized the applicability of the $team
electric regulation pR limitat-ion as applicable to low volume
waste streams when such wastewaters are commingled with
(once through) cooling waters® The interpretation that I
provided was not in accord with prior information and Instruc-
tions provided to ERA and State permitting authorities on
this subject®
The phi limitation per Part 423 applies at the "end—
of-pipe" discharge to surface waters when the wastewater discharge
contains low volume wastewater that is commingled'with once -
through cooling water. However, the intent of Part, 423 is
also that the total suspended solids and oil and grease
limitations applicable. -t -o low volume waste streams be applied
to the low volume Waste component of such a Combined discharge
Prior to Commingling of the individual Idaste Streams.

Dear Ms. Basch:
This is in response to- your gxiostinns during cur
discussion on June 21 regarding the effluent limitations
guidelines for the steam electric industry (40 CER Pant 423),
T e p1l limitation to low volume waste stream -S
is int ded tc� u
rec�i-r-e "that low volume waste streams he
treated, as necessary, to comply with the pH limitation prior
to discharge. Furthermore, the basis for compliance with the
pH limitation is not buffering or dilution provided by cooling
waters or other waste streams which are commingled with low
volume wastes.
I trust: that this information is responsive to your
questions, Please call me if you have any further questions.

use of chlorine will not result in chronic exposure to aquatic life.
Effluent Guideline Limit (Instantaneous Maximum) Outfall 001
In the effluent guidelines for the "Steam Electric Power Generating Point Source Category",
EPA has established a technology-based maximum discharge concentration of 0.2 mg/l for total
residual oxidants ("instantaneous maximum"), based on the best available technology
economically achievable (BAT). The 0.2 mg/L "maximum concentration" limit is an
"instantaneous maximum"limit, meaning that it is the value that shall not be exceeded, at any
time, as clarified in EPA's July 27, 1992, Memorandum from Cynthia Dougherty, Director of the
Permits Division, to the Regional Water Management Division Directors. This technology-
based effluent limit applies to plants with a total generating capacity of more than 25 megawatts
and once -through cooling water systems. Each individual generating unit is prohibited from
discharging chlorine for more than two hours per day, unless the discharger demonstrates to the
permitting authority that a longer duration is necessary in order to control macro -invertebrate
growth. In addition, simultaneous multi -unit chlorination is permitted according to the effluent
guidelines.
Currently, Canal Station is cooled via an open cycle system (Once -Through Cooling Water).
Biofouling of the Units 1 and 2 condenser tubing is controlled by the addition of chlorine, as
sodium hypochlorite (NaOCI), to the cooling water. During the summer months, the NaOCI
pumps for each Unit activate for one hour two times per day. Thus, each Unit receives a total of
2 hours of chlorination per day.
The above derived, technology-based TRO limit shall be measured at Outfall 001, prior to
discharge into the Cape Cod Canal. As noted above, the effluent guidelines specify that permit
limits for TRO shall be setas an "instantaneous maximum." EPA is not aware of continuous
chlorine monitoring equipment for use in salt or brackish water that currently satisfies the
analytical requirements of 40 C.F.R. Part 136, Table 1B. Therefore, in order to more accurately
determine that the concentration is below the limit for the duration of the chlorination event,
EPA requires that at least one sample is collected and analyzed every half hour during
chlorination.
Subject to the restrictions discussed above, the Draft Permit authorizes the use of chlorine as the
biocide for the Unit 1 and 2 condensers. Except for chlorine, no other biocide shall be used
without prior written approval from the EPA and MA DEP.
4.4.2 pH
The pH range for Class SB waters is from 6.5 to 8.5 standard units (s.u.) and not more than 0.2
units outside of the normally occurring range as defined in the Massachusetts Surface Water
Quality Standards, found at 314 C.M.R. 4.00. Unless otherwise specified, pH shall be measured
at Outfalls 001 and 002. Monitoring for pH at the internal outfalls 010, 011, and 012 is not

necessary as explained in EPA's March 21, 1986, Memorandum from Charles Kaplan, EPA's
National Steam Electric/Water Expert, to Regional Permit Branch Chiefs and State Directors.
Using dilution to accomplish the neutralization of pH is preferable to adding chemicals.
4.4.3 Polychlorinated Biphenyl Compounds
Pursuant to 40 C.F.R. Part 423, discharge of polychlorinated biphenyl compounds (PCBs) is
prohibited and any PCB's at the facility must be disposed of in accordance with 40 C.F.R. Part
761.
4.4.4 TSS
The quantity of Total Suspended Solids (TSS) that can be discharged from low volume waste
streams, fly ash transport water and metal cleaning wastes is limited under 40 C.F.R. § 423.12
"by multiplying the flow of low volume waste sources times the concentration listed in the
following table," which is 100 mg/1 daily maximum and 30 mg/l monthly average. The Draft
Permit contains TSS limits based on these requirements. In addition, 40 C.F.R. § 423.12(b)(11)
states that the permitting authority has the discretion to express the limits as concentration -based
as opposed to mass -based. The Draft Permit includes concentration -based TSS limits for Outfall
locations 010, 011, and 012.
4.4.5 Oil and Grease
The current permit's maximum daily limit for OiI and Grease for Outfall locations 010, 011 and
012 is 15 mg/l. Although 40 C.F.R. § 423.12 sets a maximum daily limit for Oil and Grease of
20 mg/1, the current permit limits will be maintained in the Draft Permit in accordance with
"anti -backsliding" provisions. Similarly, the average monthly limit is 10 mg/L in the current
permit for Outfall locations 010 and 011, which will be maintained in the Draft Permit. There is
no average monthly limit for O&G in the Station's current permit for Outfall 012. Therefore, in
accordance with 40 C.F.R. § 423.12, the average monthly limit in the Draft Permit for location
012 is 15 mg/L.
4.4.6 Copper
The applicable technology-based national effluent limitation guideline for copper specified in 40
C.F.R. Part 423 is based on the concentration of copper in the metal cleaning waste flow. The
metal cleaning waste stream is routed to one of two waste treatment tanks (Outfall 011) prior to
discharge into the discharge canal. The effluent limitation guidelines set a maximum daily limit
of 1.0 mg/1 and a 30 -day average value of 1.0 mg/1. These limits are included in the Draft
Permit.

Subject: EPA comments on the draft NPDES permit for Duke Shearon Harris Nuclear Plant
Hi Teresa,
-Per my voice mail message to you this morning, below are my comments on the draft permit for the Shearon Harris
plant
1. 1 believe the values for some of the penalties in the standard conditions are outdated. Please see the link below for
values that will be effective August 1, 2016. 1 pretty sure these values pertain to both state- and EPA -issued NPDES
permits.
https://www.gpo.gov/fdsys/pkg/FR-2016-07-0I/pdf/2016-154I1.pdf
I recommend the permit include a specific reopener clause that will allow NC to automatically modify/re-open
the permit to include actual interim limits for copper and zinc as part of the compliance schedule once the
Corrective Action Plan is finalized and approved by NC. The current version of the permit does not include
details pertaining to milestones. See the attached EPA memo on compliance schedules.
The permit should require instream monitoring so that actual hardness values can be obtained and eventually
be used to calculate metal limits in the subsequent permit.
Thanks,
Karrie-Jo

RPA Permitting Guidance QBELs for Hardness -Dependent Metals - Freshwater
The Reasonable Potential Analysis (RPA) is designed to calculate the allowable instream concentrations
for permit limitations. Limitations are required based upon a showing of "reasonable potential" to exceed
water quality standards. If monitoring for a particular pollutant indicates that the pollutant is not present
(i.e. consistently below detection level), then the Division may remove the monitoring requirement in the
reissued permit.
1. To perform a RPA on the Freshwater hardness -dependent metals the Permit Writer compiles the
following infonnation:
• Critical low flo of the receiving stream, 7Q10 (the spreadsheet automatically calculates
the 1 Q 10 using the formula 1 Q 10 = 0.843 (7Q 10) 0.993)
• The mean annual receiving stream flow (QA), for carcinogen comparisons against HH
criteria
• The minimum average flow over 30 consecutive days that has an average recurrence of
once in two years (30Q2) in the receiving stream, for comparisons against aesthetic
standards
• effluent hardne s and upstream hardness, site-specific data is preferred
• Permitted flow
• Receiving stre in classification
2. The chronic Aquatic Ljfe water quality criteria is converted from total recoverable metal at lab
conditions to dissolved lab conditions for the following metals: cadmium, copper, lead, nickel,
zinc, and trivalent chromium. EPA default partition coefficients, or site-specific translators
developed using federally approved methodology, are used in the RPA spreadsheet to convert the
dissolved lab conditions to a total recoverable metal at ambient conditions.
3. The acute Aquatic Life water quality criteria is converted from total recoverable metal at lab
conditions to dissolved lab conditions for the following metals: cadmium, copper, lead, nickel,
zinc, silver and trivallInt chromium. EPA default partition coefficients, or site-specific translators
developed using federally approved methodology, are used in the RPA spreadsheet to convert the
dissolved lab conditions to a total recoverable metal at ambient conditions.
4. For criteria that are hardness dependent, site-specific hardness data (effluent and upstream) is best
to evaluate chronic a d acute concentrations. The permit writer will first review DMR's, Effluent
Pollutant Scans, and oxicity Test results for
any hardness data and then contact the Permittee to
see if any additional data is available for instream hardness values, upstream of the discharge.
If no hardness data iavailable, the permit writer may choose to do an initial evaluation using a
default hardness of 2J5 mg/L and total suspended solids (TSS) of 10 mg/L to see if the permittee is
impacted. Minimum and maximum limits on the hardness value used for water quality
calculations are 25 g2 and 400 mg/L respectively. The minimum TSS value used for EPA
partition coefficient is 10 mg/L.
Page 2 of 4

If the use of a default hardness value results in a hardness -dependent metal showing reasonable
potential to violate water quality criteria the permit writer should contact the Permittee and
request 5 site-specific effluent and upstream hardness samples.
The overall hardness value used in the water quality calculations is calculated as follows:
Combined Hardness (chronic)
_ (Permitted Flow*Avg Effluent Hardness) x (7Q10 S*Avg. Upstream Hardness)
(Permitted flow + 7Q10 S)
The Combined Hardness for acute is the same but the calculation uses the IQ 10 flow.
5. EPA default partition coefficients or the "Fraction Dissolved" converts the value for dissolved
metal at laboratory conditions to total recoverable metal at in -stream ambient conditions. This
factor is calculated using the linear partition coefficients found in The Metals Translator:
Guidance for Calculating a Total Recoverable Permit Limit from a Dissolved Criterion (EPA
823-B-96-007, June 1996) and the equation:
Cdiss = 1
Ctotal 1 + { [Kpo] [ss(t+a)] [10-6] }
Where: ss = in -stream suspended solids concentration [mg/l], minimum of 10 mg/L used
Kpo and a = constants that express the equilibrium relationship between dissolved and
adsorbed forms of metals. A list of constants used for each hardness -dependent metal can
also be found in the RPA program under a sheet labeled DPCs.
6. The dissolved hardness -dependent metals calculations are divided by the default partition
coefficients (or translators) to obtain a Total Recoverable Metal at ambient conditions. Dissolved
metals that do not have translators or default partition coefficients are divided by one. All other
standards (HH, WS, non -hardness dependent metals) are automatically shown in Table 2 of the
RPA spreadsheet when the program is initiated.
7. The standards, criteria, and calculated Total Recoverable metals listed in Table 2 of the RPA
spreadsheet are inserted into a mass balance equation to determine the total allowable
concentration (permit limits) for each pollutant using the following equation:
Ca = (s7Q 10 + Qw) Cwgs) — (s7Q 10) (Cb)
Qw
Where: Ca = allowable effluent concentration (µg/L or mg/L)
Cwqs = NC Water Quality Standard or federal criteria
Cb = background concentration (assume zero for all toxicants except NH3)*
Qw = permitted effluent flow
S7Q10 = summer low flow used to protect aquatic life from chronic toxicity and human
health through the consumption of water, fish, and shellfish from noncarcinogens
* Discussions are on-going with EPA on how best to address background concentrations
Flows other than S7Q10 may be incorporated as applicable:
1Q10 = used in the equation to protect aquatic life from acute toxicity
QA = used in the equation to protect human health through the consumption of water, fish,
and shellfish from carcinogens
30Q2 = used in the equation to protect aesthetic quality
The total allowable concentration (permit limits) are shown on the "RPA Sheet" in the RPA
spreadsheet.
Page 3 of 4

8. Effluent toxicant data is e0tered into the "Data Sheet." of the RPA spreadsheet which uses
statistics to estimate the 95"' percentile concentration of each pollutant. These concentrations are
listed as the Predicted mai concentrations on the "RPA Sheet" in the RPA spreadsheet. The
Predicted Max concentrations are compared to the Total allowable acute and chronic
concentrations to determi�e if a permit limit is necessary. This is in accordance with the U.S.
EPA Technical Support Document for Water Quality -Based Toxics Control published in 1991.
9. Effluent hardness sampling and instream hardness sampling, upstream of the discharge, is being
inserted into all permits Iith facilities monitoring for hardness -dependent metals to build a more
robust hardness dataset. 7

Permit Application Amendment
Dear Mr. Belnick:

The current NPDES permit for the Harris Nuclear Plant (HNP) expired on July 31, 2011.
In January 2011, Duke Energy Progress (DEP) submitted a timely renewal application which is
currently under review by your staff. DEP submitted an NPDES permit application amendment
request on May 22, 2014 to address a power uprate, sewage treatment plant improvements,
and changes to wastewater management practices. DEP hereby amends the NPDES permit
application to reflect several additional changes since the May 22, 2014 permit application
amendment notification.
I. Corporate Name Update
The current Corporate name is Duke Energy Progress, LLC and DEP requests that all
permit documents and NPDES related electronic datasets be updated to reflect this name. .
II. Sewage Treatment Plant Improvements (Outfall 002)
The existing HNP sewage treatment plant,is permitted to discharge 25,000 gpd of
domestic wastewater; however it was upgraded to process 40,000 gpd as explained in the May
22, 2014 permit application amendment notification. Subsequent to this upgrade to 40,000
gpd, it has become apparent that additional capacity is needed to accommodate hydraulic and
organic loadings associated with episodic facility maintenance activities such as outages for
refueling and/or equipment maintenance. DEP is .requesting Outfall 002 be permitted for a
monthly average flow value of 0.065 MGD.
The upgrade will involve the installation of two primary treatment tanks, three 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. This
treatment is expected 'to be operational by August 1, 2016. DEP is diligently working to
complete this sewage treatment plant expansion ahead of a planned early October 2016
outage. Our desire is to avoid the need for any temporary storage of raw or treated wastewater
during this upcoming outage. DEP understands that an Authorization to Construct (ATC) is not

Serial: HNP-16-04.1/page 2
required to install this treatment system upgrade and the discharge from Outfall 002 may not
exceed a monthly average flow of 25,000 gpd under the current NPDES permit.
. In support of DEP's request to increase the permitted flow at Outfall 002, we have
modified and attached the affected portions of Form 2C Attachment 3 and Attachment 4 from
our application package.
If there are any questions regarding the enclosed information, please contact Mr. Don
Safrit at (9 19) 546-6146.
1 certify, under penalty of law, that this document and all attachments were prepared under
My direction or supervision in accordance with a system designed to assure that qualified
personnel properly gather and evaluate the information submitted. Based on my inquiry of
the person or persons who manage the system, or those persons directly responsible for
gathering the information, the information submitted is, to the best of my knowledge and
belief, true, accurate; and complete. l am aware that there are significant penalties for
submitting false information, including the possibility of fines and imprisonment for knowing
violations.

HARRIS NUCLEAR PLANT
The Harris Nuclear Plant (HNP) consists of a 930 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 normally 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 permit 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 5).
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
25°17.) 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 performance.
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
I

National Pollutant Discharge Elimination System Permit Number NCO039586
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 0.015 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) and a 0.025 MGD recirculating packed bed filter system consisting of
two primary treatment tanks and three AX -Max treatment units. Disinfected effluent is pumped
through a sand filter (added to help with TSS issues) to common outfall. 006. Currently, sludge is
land'applied offsite by a contract disposal firm (Granville Farms, Inc., Permit No. WQ0000838).
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.
The existing 0.040 MGD sewage treatment facility is currently being expanded to a firm capacity
of 0.065 MGD to accommodate hydraulic and organic loadings associated with episodic facility
maintenance activities such as outages for refueling and/or equipment maintenance. The
expansion facility components consists of two primary treatment tanks, three 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.
In addition to sanitary waste, HVAC condensate is discharged to the sewage treatment facility.
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.

National Pollutant Discharge Elimination System Permit Number NCO039586
Outfall 004 - HNP Low -Volume Wastes discharge to Outfall 006
In the operation of the HNP, there are many processes which result in intermittent 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. Annually 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 in (such as nitrites, molybdates, ammonia, hydrazine,
carbohydrazide, and ethanolamine), acids and bases from water treatment processes, and
I astewater 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 demineralizer 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 wetlayup
d) Non -radioactive secondary waste from condensate polishers
e) Miscellaneous drains/leaks from condenser, steam generator, and secondary components
f) Auxiliary boiler system blowdown
g) Miscellaneous waste streams not otherwise identified elsewhere in this application.
Outfall 005 HNP Radwaste 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

Progress Energy Carolinas, LLC
Harris Nuclear Plant and Harris Energy & Environmental Center
National Pollutant Discharge Elimination System Permit Number NC0039586
streams are collected in tanks and sampled for conventional pollutants and radioactivity. The
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 than 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 HNP Discharge's
1. 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. Upflow filter clear well drains
The upflow filter clearwell stores filtered lake water which is used in the potable
Water treatment system. Periodically, some of the water from this tank is drained
to the storm drains that discharge to Harris Lake. This water may contain low
concentrations of chlorine because sodium hypochlorite is added to control
biological growth in the tank prior to treatment through the up flow filter.
b. 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
4

Progress Energy Carolinas, LLC
Harris Nuclear Plant and Farris Energy & Environmental Center
National Pollutant Discharge Elimination System Permit Number NCO039586
heat the feedwater. The condensed steam is discharged to the storm drains that
flow to Harris Lake at approximately 5 - 10 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
time, the temperature of the condensed steam should be at ambient temperature
upon reaching the lake.
c. Condenser water box drains
Prior to condenser maintenance or repairs it is 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.
d. Filtered water storage tank
Water from the upflow filter clearwell 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 this. tank may be
drained to the storm drains that discharge to Harris Lake. This water may contain
trace amounts of chlorine.
.e. Fire protection system
Approximately 5000 gallons of lake water used for annual testing of the fire
protection system is routed to .most of the storm drains that discharge to Harris
Lake. In the event of a fire, additional water could be discharged to storm drains.
Condenser hotwell
During outages (approximately once per 18 months) it is necessary to drain the
condenser hotwell for condenser maintenance and inspection. Approxmiately
70,000 gallons of this water resulting from condensed steam is drained to storm
drains that discharge to Harris Lake. It may contain trace amounts of
ethanolamine, 100 ppb or less of -.boron,' and 100 ppb or less ammonia.
g. Condensate storage tank
Infrequently it is necessary to drain the condensate storage tank for maintenance.
Approximately 400,000 gallons per event is drained to storm drains that discharge
to Harris Lake. It may contain 200 ppb or less boron, 1000 ppb or less ammonia,
and trace .hydrazine,
h. Air conditioning system condensate

Progress Energy Carolinas, LLC .
Harris Nuclear Plant and Harris Energy & Environmental Center
National Pollutant Discharge Elimination System Permit Number NC0039586
The condensate from various building air conditioning systems flows to various
storm drains 'to Harris Lake. The volume is generally low and is greatest in the
humid summer months.
i. 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 storm
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; normal 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 storm drain system. In addition,
the facility may find it necessary to wash equipment with demineralized water
with the discharge to storm drains
2. 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 testing purposes or for containment cooling as needed. This water may
contain traces of chemicals identified for the cooling tower blowdown.

radiological wastewater, receive treatment in the 0.020 MGD 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 10 days followed
by a stabilization pond, also witha, minimum retention time of 10 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
MGD. In addition to the approximately 235 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 0 to 450 additional people per day).
Wastewater from the HNP may also be conveyed 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 0.001 MGD. 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 virtually all oily wastes are
drummed for off-site disposal. Laboratory wastes that are not drummed may go to one of two
5,000 gallon holding/neutralization tanks for visual inspection and testing before , being
discharged to the influent pump station.

Cooling Tower Blowdown
Cooling tower blowdown from the HE&EC air conditioning system averages approximately
0.002 MGD. Chemical additives include an algicide (aqueous glutaraldehyde solution) and a
suspension agent. The treatment and extended retention time in the ponds should ensure no
algicide is discharged to Harris Lake.
Radiological Wastewater
The majority of the radiological wastewater results from the cleaning of laboratory glassware. In
addition, small quantities of liquid radiochemistry laboratory samples, radioactive metallurgy
laboratory wastewater (which is prefiltered with a paper cartridge to remove particulates before
disposal), liquids generated from analyses of plant 10 CFR Part 61 samples, and reagents are
disposed via the HE&EC radiochemistry laboratory drains to a holding tank. Approximately
5,000 gallons are discharged annually from the holding tank, as allowed by the radioactive
materials License No. 092-02.18-4, issued by the N.C. Division of Radiation Protection. The
effluent from the radiological holding tank combines with the effluent from the sewage treatment
plant and discharges into Harris Lake.
Radiochemical analyses 'are performed prior to release to calculate the total activity in the waste.
These analyses include gamma spectrum analysis using intrinsic germanium gamma
spectrometry systems, as well as direct analysis for Tritium, Iron -55, Nickel -63 and Strontium -
89790. Individual radionuclides have different release limits, however, the total Tritium activity
discharged per calendar year shall not exceed 20 millicures, and the total activity excluding
Tritium discharge per calendar year shall not exceed 5 millicuries.
Additionally, the pH of the wastewater is determined before release. The pH must be between
six and nine and is adjusted,'if necessary, using 50% sodium hydroxide. The tank is agitated
after addition of the sodium hydroxide, and ail additional sample is analyzed to verify that the
appropriate pH adjustment is achieved.
Stormwater
Stormwater runoff from the HE&EC is composed of parking lot, roof, and lawn drainage. This
non -industrial stormwater is not subject to the Phase I stormwater regulations of 40 CFR Part
122.'

Duke Nukes/Stormwater Permitting
Bradley- Teresa and I met with Duke Energy/Don Safrit et al today on some of their nuke permits. Currently their nuke
plants are covered as follows:
1. Duke McGuire-' has separate wastewater permit (NC0024392) and stormwater permit.
2. Duke Shearon Harris- has combined wastewater/stormwater covered under NC0039586. There are 9+
stormwater outfalls identified in this permit. This permit expired 7/31/2011, and NPDES has not started renewal
due to manganese issue. When we do start our renewal, I would like to jettison the stormwater component.
3. Duke Brunswick- has combined wastewater/stormwater covered under NC0007064. Previous application listed
3 stormwater outfalls of minor concern, and no specific stormwater outfalls are identified in permit aside from
generic "stormwater". This permit expires 11/30/2016.
Duke/Don is getting ready to submit NPDES renewal app for Duke Brunswick and mentioned stormwater/EPA Form
2F. NPDES responded that we are now in process of separating wastewater from stormwater permits, so he wants to
know how to proceed with that application. What has been your process to notify Duke of need to apply for separate
stormwater coverage. Thanks.

Material Handling and.Storage Practices
`O Potential sources of pollutants to storm water discharges include material receiving,
storage,. and handling areas; waste handling storage, and disposal areas; and runoff
from inside the Protected Area. Exposure. of pollutants to storrn water may be a result
of material storage or handling practices; oras a result<of spills or leaks. Materials
identified as being of greatest significance.: are lubrication oils, fuel oils, transformer
fluids, and chemicals. Secondary.containments for oil are maintained in accordance
wifh the Spill Prevention Control and Countermeasure Plan (SPCC Plan).
Material Handling Practices
The majority of materials received at the HNP are brought to the receiving warehouse
and temporarily stored in the warehouse. The m 'ority of the materials are then loaded
onto a trailer and transferred to the stores issue warehouse, bulk warehouse, or
.chemical warehouse inside the Protected. A'" ' Butk:quantities of fuel oil are brought
into the 1 plantby1ankertrucks and unloaded iniac cordance,with°theSPCG Plan. Liquid
hydrogen, liquldoxygen, li4gid chlorihe, and polymer are brought to the. site bytanker
trucks. and unloaded at the appropriate -storage tank.
Material: Storage' Practices
Lubrication Oils and Fuel Oil
Major storage locations of fuel oil.,and lubrication oils are monitored and controlled.
Operators perform daily routine -checks of oil storage.and handling areas inside the
Protected Area, in- accordance with' approved; plant proceduras: Routine transfers of oil
from delivery trucks; oil leaks and/or, spills are c:ontrolied and monitored per the SPCC
Plan requirements and implementing plant procedures. Outside storage of oils is
contained as per the SPCC Plan,
Solid Waste Handling and StoragQ
Chemical -waste and Used Oil produced inside of the protected area is initially
processed in the chemical processing area west of the paint shop. This area is
sheltered fromthe weather and the drains -in the area.are routed to the Oily Waste
Separator for processing.
Used Oil and -waste chemical pro0u,v6d,outside of" protected area is stored in
Warehouse 6 and the Used Oil Storage area iocated' east of the Mobil . Equipment
Shop. The Used Oil Storage area contains two diked tanks for Used Oil and another
diked area for small tanks and drums. Storm .water in the diked area is visually
inspected before release to the storm -water system.
