Hydrazine is a chemical used to remove dissolved oxygen: Oxygen promotes
general corrosion and pitting of ferrous and copper surfaces. One ppm of
hydrazine will react with one ppm of dissolved oxygen as follows
nitrogen and water: to form
NA + 02 N2 + 2H 20"" i
The reaction rate is dependent upon temperature, pH, and concentration.
In addition, hydrazine thermally decomposes at temperatures above 400°F
to form ammonia.
All wastes that might contain hydrazine flow via plant drains to the low-
volume waste treatment system_ that consists primarily of two 230,000 gallon
neutral. i zat i or- basins, followed by. a 1,000,000 gallon sedimentation basin.
The neutralization -sedimentation basins operate on a batch -process mode. When
the appropriate treatment levels are reached, the treated water is pumped to
the cooling tower blowdown line at 500-800 gpm.
The cooling tower blowdown line usually maintains a minimum flow of
900 gpm (1.3 MGD) even when the plant is not operating. During normal
operation, the cooling tower blowdown is a continuous flow of about 2 to
6 MGD.
Hydrazine is normally used in plant systems that treat and recycle their
blowdown, and, therefore, the small amounts of hydrazine released are due .to
minor leakage or maintenance work. There are essentially four sources of
hydrazine wastes to the low-volume waste treatment system:
1. Auxiliary Boiler System: blowdown of 5-10 gpm with a hydrazine
concentration of approximately 0.1 ppm.
2. Main Steam System: No blowdown; miscellaneous leaks may produce
10-20 gallons per day at 100-300 ppb hydrazine.
3. Regeneration of condensate polishers (ion -exchange) will produce
65,000 gallons per event (every other day) with less than 50 ppb
hydrazine.
The above sources of hydrazine are such low qualities or concentrations
that after mixing with other waste flows in the neutralization basins,
the hydrazine should be well below any level of concern. The remaining
source is the only one that is likely to produce hydrazine wastes at
concentrations that might remain detectable after routine treatment.
4. Wet lay-up of steam generators and miscellaneous steam cycle
systems: When the plant is taken off-line for an extended period,
such as a refueling outage, the steam generators and steam cycle
systems may be" filled with water and a hydrazine residual of
75-200 ppm is maintained to prevent corrosion. This may happen

indicates that each nitrogen atom should be spa hybridized with bond angles close to
109.50•(the tetrahedral angle) since the nitrogen atom is surrounded by four electron;;
pairs. The observed structure with bond angles of 112° (see Fig. 19.8) agrees with
these predictions. Hydrazine, a colorless liquid with an ammoniacal odor, freezes at
2°C' and boils at 113.5°C. This boiling point is quite high for a compound with a
molecular weight of 32; this suggests that considerable hydrogen bonding must
occur among the polar hydrazine molecules.
Hydrazine is a powerful reducing agent and has been widely used as a rocket
propellant. For example, its reaction with oxygen -is highly exothermic:
;'•
N2114(1) + N + 2H AH' _ —622 kJ^"'
Since hydrazine also reacts vigorously with the halogens, fluorine is often used

instead of oxygen as the oxidizer in rocket engines. Substituted hydrazines, where
one or more of the hydrogen atoms are replaced by other groups, are also useful
rocket `eels. For example, monomethylhydrazine,

is used with the -oxidizer dinitrogen tetroxide (N204) to power the U.S. space shuttle
orbiter. The reaction is
5N,04(l) + 4NA(CHAO ---)' 12H2O(g) + 9N2(g) + 4CO2(g)
Because of the large number of gaseous molecules produced and the exothermic
nature of this reaction, a very high thrust per weight of fuel is achieved. The
reaction is also self-starting—it begins immediately when the fuels are mixed—
which is a useful property for rocket engines that must be started and stopped
frequently.

Using the bond energies in Table 8.4 (Chapter 8), calculate the approximate value

The bonding in N204 is described by resonance structures that predict the N-0

The use of hydrazine as a rocket propellant is a rather specialized application.
The main industrial use of hydrazine is as a "blowing" agent in the manufacture of
plastics. Hydrazine decomposes to form nitrogen gas, which causes foaming in the
liquid plastic, which results in a porous texture. Another major use of hydrazine is
in the production of agricultural pesticides. Of the many hundreds of hydrazine
derivatives (substituted hydrazines) that have been tested, 40 are used as fungicides,
herbicides, insecticides, and plant growth regulators.
The manufacture of hydrazine involves the oxidation of ammonia by the hypo-
chlorite ion in basic solution:
2NH3(aq) + OCl—(aq) —> N-H4(aq) + Cl—(aq) + H2O(l)
Although this reaction looks straightforward, the actual process involves many steps
and requires high pressure, high temperature, and catalysis to optimize the yield of
hydrazine in the face of many competing reactions.
' Nitrogen Oxides
Nitrogen forms a series of oxides in which it has an oxidation state from +1 to +5,
an as shown in Table 19.2 on the following page.
` Dinitrogen monoxide (N20), more commonly called nitrous oxide or laughing
' gas, has an inebriating effect and is often used as a mild anesthetic by dentists.
r " - Because of its high solubility in fats, nitrous oxide is widely used as a propellant in
tk aerosol cans of whipped cream; it is dissolved in the liquid in the can at high
pressure and forms bubbles that produce foaming as the liquid is released from the
can. A significant amount of N20 exists in the atmosphere, mostly produced by soil
Blowing agents, such as hydrazine
which forms nitrogen gas on
decomposition, are used to produce
porous plastics like these styrofoam
chips.

and chlorophytes. Algal populations were relatively low in 1990 with the phytoplankton
community being dominated by a small cyanophyte, Lvnebya species. The low algal biovolume
may be attributed to the presence of the weedy, aggressive macrophyte, Hydrilla, which provides
shading and utilizes available nutrients. The change in status from eutrophic to mesotrophic is due
primarily to a decrease in chlorophyll a and an increase in Secchi depth during the last two
sampling dates.
Harris Lake was sampled for its potential to support algal growth via the Algal Growth
Potential Test (AGPT) in July, 1991. Five sites .were sampled. Of these, four sites were found to
be co-limited by nitrogen and phosphorus, and one site was nitrogen limited. Control Mean
Standing Crop (MSC) for these five sites ranged from 0.18 mg/l to 2.32 mg/l, indicating a low
probability for the lake to support excessive algal growth.
This relatively new lake contains an extremely diverse population of aquatic macrophytes. At
least 58 species of aquatic plants have been collected and identified from, and adjacent to, this body
of water-8. One of the species present is Hydrilla verticillata (hydrilla). In 1990, areal coverage for
this aquatic macrophyte was eight times the areal coverage observed in 1989, however, the
operation of the nuclear power plant has not been impacted and hydrilla has not spread beyond a
depth of less than three meters within the littoral zone9. Due to hydrilla's potential to spread
rapidly, it is a species CP&L is actively trying to control. Because the presence of the hydrilla
beds may have coritrributed to the improved fisheries observed in the lake, efforts have been
centered on reducing the plant coverage at the boat launcheslo
Colonization of the lake by the Asiatic clam rbicula fluminea) was observed by CP&L in
1988, and the size distribution of specimens collected indicated that the population has been in the
lake for approximately two years. These exotic clams were thought to have been introduced by
boaters' 1. Asiatic clams were also observed in the lake in 1990, but were not presenting a problem
to the power plant water intakes12. Also in 1990, two monthly mean chlorophyll a concentrations
were found to be above the North Carolina standard of 40 µg/1(72.5 µg/1 in May near the dam and
63.4 µg/1 in March in the Buckhorn Creek arm of the lake)13 ` }

Harris Lake
Harris Lake is 4.4,150 acre (1,680 hectare) impoundment constructed in 1983 to provide
cooling water for the Shearon Harris Nuclear Power Plant. It is also used for recreation. The lake
is owned by Carolina Power and Light (CP&L), who conducts annual monitoring of the chemical,
physical, and biological components. Harris Lake is located on Buckhorn Creek. Other
significant tributaries to the lake include White Oak Creek, Little White Oak Creek, Thomas Creek,
and Tom Jack Creek. Maximum depth is 20 feet (six meters) and the shoreline length is 40 miles
(64 kilometers). The watershed, characterized by rolling hills, consists primarily of forest and
agriculture covering 70 mit (1811tm2).
Harris Lake was most recen6l, sampled.by DEM on August 26, 1993. Physical measurements
indicated that the lake was stratified at all sampling locations with the thermocline occurring at a
depth of three to five meters. Dissolved oxygen ranged from 8.1 to 8.5 mg/l at the surface,
dropping off to anoxic conditions �t the bottom. Surface temperature was approximately 29.0°C.
Mean pH was 7.2 at the surface d mean surface conductiN -Ity was 81 µmhos/cm. Total
phosphorus levels were moderate, while total organic nitrogen levels were elevated. The mean
chlorophyll a value was 9 µg/1. is low chlorophyll a concentrations signified little planktonic
production. However, a large inv ive, filamentous cyanophyte, Lvnebya w 11 i, was found
growing near the shoreline. This lue-green alga forms extensive mats, has a tough sheath and is
resistant to desiccation. Although this species has not been reported to be a nuisance yet in Harris
Lake, L. w 11 i has become a pro lem- in other reservoirs in the southeastern U.S. Fecal coliform
bacteria and metals were below la oratory detection limits. With a NCTSI score of -0.2 in 1993,
Harris Lake is classified as mesotrophic and is Threatened due to elevated nutrients. Harris Lake is
currently designated as Class C.
Harris Lake was previously sampled by DEM in 1987, 1989, and 1990. In 1989, a eutrophic
indicator, Aphanizomenon flos-a.Iuae, was dominant among the algal community. Several classes
of algae other than cyanophytes w�re well represented including euglenophytes, dinoflagellates,

Clarification of Toxicity Test Sample Type
We have reviewed the CP&L letter to you dated May 17, 1995
requesting changing the toxicity sample type to a 24 hour composite
from a grab. CP&L believes the 24.hour composite would be a more
representative sample to test for acute toxicity. We have
conferred with Kristie Robeson of the Aquatic Toxicity Group on
this matter and she also has no problem modifying the sample type..::-)
CP&L also states in the letter that Part I (A) and Part III (E) of.

Clarification of Toxicity Test Sample Type

Carolina Power & Light Company (CP&L) recently became aware that the subject NPDES Permit contains
a discrepancy regarding the sample type required for effluent toxicity testing. Part I (A) of the Permit for
outfall serial number 001 states that a "grab" sample be used for acute toxicity testing. However, Part III (E)
states that the sample type should be "a 24-hour composite."
CP&L believes that a 24-hour composite sample is the most representative sample of the facility's effluent to
test for acute toxicity. Therefore, CP&L requests that the two (2) affected pages of Part I (A) of the Permit
be reissued to state that toxicity testing at outfall serial number 001 be performed using a 24-hour composite
sample. `
Because the new wastewater treatment facility began discharging in March 1995, thednitial toxicity testing
must be performed in May 1995. Your timely reissuance of the Part I (A) pages is urgently needed.
CP&L appreciates the continued cooperation demonstrated by the NCDEM staff in responding to its requests.
If you have any questions or require additional irfmTration, please contact Mr. K. A. Bridcman w !9191 362-

Note for Jason Doll
From: Coleen Sullins

Subject: RE: Shearon Harris NPP
To: Jason Doll
Cc: Dave Goodrich
Jason - I would recommend giving them the option that all the other power plants get
(calculations or monitoring), since the data (yes it is limited) has not, shown anything. They
have to do one at every renewal for the application. Given that we have not seen anything in
results that we have reviewed to date on power plants, that I am aware of, that should be
sufficient in my opinion.
Dave - if you disagree, please let me know. Thanks Coleen

Subject: RE: Shearon Harris NPP
To: Coleen Sullins
I wanted to reply for the record. There were three priority pollutant scans available for
evaluation with this renewal, counting the one with their application. The three scans
showed no detections for parameters having state or federal water quality standards, so my
recommendation was not based on previous data. Rather, it came from a precautionary
approach. In the application CP&L submitted a laundry list of chemicals used at the facility,
and it is a substantial list, to say the least. In addition, the wastestreams other than the
cooling tower and the sanitary system have a variety of wastes coming from so many diffuse
sources as to produce some degree of paranoia on my part. However, I have the ability to
step back and be objective about it, so i do not feel strongly about the recommendation, and I
would not object to removing the requirement from the permit based on your
recommendation.

To: Jason Doll
Cc: Dave Goodrich
I have a question, what have the previous analyses shown? Why should they be held to a
different standard if we haven't seen anything in the analyses that have been done in the past.
Or, have they been doing the actual analyses, just the calculations? How much data is the
recommendation being based on? Coleen

annual scan of the 126 Priority Pollutants (ADAM). The recommendation is based on two
factors. The first is that the federal effluent guidelines for this permit stipulate that there shall
be no discharge of any detectable amounts of the 126 parameters. The guidelines state that
complinace can be judged "at the permitting authority's discretion" either by engineering
calculations or by actual monitoring. I believe that it should be demonstrated by actual
monitoring at least once a year. The second factor driving this recommendation is the five
different wastestreams and the wide array of chemicals utilized at the facility that are, in turn,
associated with them. Please let me know if you have any input in this matter, or if you
need any further information.
Thanks, Jason

stream in the furnace and in the econo-
mizer sections. Economizer ash is in -
Environmental Protection Agency
eluded when it is collected with bottom
ash.
(g) The term once through coolin
water means water passed through th
main cooling condensers in one or two
passes for the purpose of removing
waste heat.
(h) The term recirculated cooling water

moving such heat from. the water and
then passed again, except for blow -
down; through the main condenser.
(i) The term 10 year, 241hour rainfall
event means a rainfall event with a
probable recurrence interval of once in
ten years as defined by the National

1423.12' Effluent lifnitations'gaidelines
representing the degree of effluent
reduction attainable by the applica-
tion of the best practicable control
technology currently available
(a) In establishing the limitations set
forth in this section, EPA took into ac-
count all information it was able to
collect, develop and solicit with re-
spect to factors (such as age and size of
Plant, utilization of facilities, raw ma -
§423.12 .,
terials, manufacturing processes, non -
water quality environmental impacts,
9 control and treatment technology
e available, energy, requirements and
costs) which can affect the industry
subcategorization and effluent levels
established. It is, however, possible
that data which would affect these lim-
itations have not been available and, as
a result, these limitations should be
adjusted for certain plants in this in-
dustry. An individual discharger or
other interested person may submit
evidence to the Regional Adminis-
trator (or to the State, if the State has
the authority to issue NPDES permits)
that factors relating to the equipment
or facilities involved, the process ap-
plied, or other such factors related to
such discharger are fundamentally dif-
ferent from the factors considered in
the establishment of the guidelines. On
the basis of such evidence or other
available information, the Regional
Administrator '(or the State) will make
a written finding that such factors are
or are not fundamentally different for
that facility compared to those speci-
fied in the Development Document. If
such fundamentally different factors
are found to exist, the Regional Admin-
istrator or the State shall establish for
the discharger effluent limitations in
the NPDES Permit either more or less
stringent than the limitations estab-
lished herein, to the extent dictated by
such fundamentally different factors.
Such limitations must be approved by
the Administrator of the Environ-
mental Protection Agency. The Admin-
istrator may approve or disapprove
such limitations, specify other limita-
tions, or initiate proceedings to revise
these regulations. The phrase "other
such factors" appearing above may in-
clude significant cost differentials. In
no event may a discharger's impact on
receiving water quality be considered
as a factor under this paragraph.
(b) Any existing point source subject
to this subpart must achieve the fol-
lowing effluent limitations represent-
ing the degree of effluent reduction by
the application of the best practicable
control technology currently available
(BPT):
(1) The pH of all discharges, except
once through cooling water, shall be
within the range of 6.0-9.0.

(2) There shall be no discharge of pol-
ychlorinated biphenyl compounds such
as . those commonly used for trans-
former fluid.
(3) The quantity of pollutants dis-
charged from low volume waste sources
shall not exceed the quantity deter-
mined by multiplying the flow of low
volume waste sources times the con-

Dear Mr. Howard:
The current NPDES permits for Carolina Power & Light Company's (CP&L) Harris Nuclear Plant
(HNP) and Harris Energy and Environmental Center (HE&EC) located near New Hill in Wake County,
both expire on March 31, 1996. CP&L respectfully requests that the North Carolina Division of
Environmental Management (NCDEM) renew the Harris Nuclear Plant NPDES Permit (Permit No.
NC0039586) in accordance with 15NCAC 2H.0100. Furthermore, CP&L requests that, as previously
discussed with Mr. Dave Goodrich of the NCDEM Permits and Engineering Unit during a meeting with
Mr. Rick Yates of CP&L's Environmental Services Section on July 26, 1995, the one outfall currently
permitted at the HE&EC (Permit No. NC0026735) be included in the renewal of the HNP permit. Also,
as discussed with Mr. Goodrich, the HNP stormwater application pursuant to 40CFR Part 122.26 was
included in CP&L's Storm Water Group Application No. 286 previously submitted to the U.S.
Environmental Protection Agency (EPA). By reference, CP&L desires that the group application be
made part of the HNP renewal application. Copies of the group application correspondence are attached
to the enclosed application form (Attachment 8). No stormwater outfalls at the HE&EC are within the
scope of the EPA's Phase 1 stormwater regulations.
Enclosers is a check for the $400 permit renewal application fee and the "Application for Permit to
Discharge Wastewater" (Standard Form Q. As required, the application is being submitted in triplicate.
CP&L appreciates the continued cooperation demonstrated by the NCDEM staff in responding to its
permitting needs. If you have any questions or require additional information, please contact
Mr. R. T. Wilson at [phone] or Mr. Rick Yates at [phone].

DESCRIPTION OF WASTE STREAMS
HARRIS NUCLEAR PLANT
INTRODUCTION
ATTACHMENT 1A
PAGE 1 of 7
The Harris Nuclear Plant (HNP) consists of a 900 MW generating unit and associated facilities. The
HNP systems include a Westinghouse pressurized water reactor, three recirculating steam generators,
a turbine generator, a one -pass condenser, an open recirculating (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.
COMBINED HNP OUTFALL TO HARRIS LAKE
The HNP operates on an open recirculating 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.) Monthly 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).
HNP COOLING TOWER BLOWDOWN TO HARRIS LAKE
The cooling tower provides the condenser with a supply of water for removing the heat rejected by
the condensation of steam. (The recirculating water temperature rise across the condenser is 25°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.

ATTACHMENT 1A
PAGE 2 of 7
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 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 DEM on
attachments to monthly Discharge Monitoring Reports.
Several chemicals are used (or planned for use) in the treatment of the circulating water. Information
concerning these chemicals and approximate dosages are provided below. (The chemical supplier
is subject to change at any time.)

HNP SEWAGE TREATMENT FACILITY
A 0.05 MGD extended aeration sewage treatment facility serves the HNP. The facility consists of
dual -path equalization tanks, aeration tanks, sludge holding tanks, clarifiers, and chlorine contact
tanks. Disinfected effluent is pumped to the common outfall pipe. Currently, sludge is land applied
off site by a contract disposal firm (Hardee's Septic Tank Service, Permit No. WQ0000584, effective
November 9, 1993, expiration September 30, 1998). The contractor adds lime to the sludge for
stabilization. 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.
In addition to sanitary waste, HVAC condensate and organic developers from the microfilm
processing laboratory (approximately 52 gallons/year) are discharged to the sewage treatment
facility. (Hazardous and ammonia -containing components of developing waste are disposed of as
hazardous waste and low-volume waste, respectively.)
Chemicals used (and approximate quantities) in the sewage treatment facility are described below.
The chemical supplier is subject to change at any time. Chemical composition of the Betz products

HNP METAL CLEANING WASTES
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, 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.

ATTACHMENT 1A
PAGE 4 of 7
HNP LOW VOLUME WASTES
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. 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 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 wet layup
d) Non -radioactive secondary waste from condensate polishers
e) Miscellaneous drains/leaks from condenser, steam generator, and secondary components
f) Ammonia -containing wastes from microfilm processing laboratories
g) Auxiliary boiler system blowdown
h) Miscellaneous waste streams not otherwise identified elsewhere in this application.
HNP RADWASTE TREATMENT SYSTEM
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 specific batch

ATTACHMENT 1A
PAGE 5 of 7
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 HNP DISCHARGES
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. Further
description of the storm drain system was provided to NCDEM in a copy of the group
stormwater application submitted in accordance with the EPA final stormwater regulations.
A diagram and additional description of the stormwater routing system at the HNP is
provided with this application in Attachment 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 via SW -5 (see Attachment 7). 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 upflow
filter.

ATTACHMENT 1A
PAGE 6 of 7
b. Heat exchanger on the demineralizer feedwater
During the cold months, 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 via SW -5 (see, Attachment 7) 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 via SW -4
(see Attachment 7). This water is monitored for selected cooling tower blowdown
parameters.
d. Filtered water stora a tank
Water from the upflow filter clearwell is treated with carbon filters for turbidity
control and then stored in a tank prior to subsequent filtration and disinfection.
Occasionally, some water from this tank may be drained to the storm drains that
discharge to Harris Lake via SW -5 (see Attachment 7). 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.
f. 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 via SW -4 (see Attachment 7). It may contain trace amounts
of ethanolamine, 100 ppb or less of boron, and 100 ppb or less ammonia.

ATTACHMENT 1A
PAGE 7 of 7
g. Condensate storaize 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 via SW -4 (see Attachment 7). It may contain 200 ppb or less boron,
1000 ppb or less ammonia, and trace hydrazine. ..
h. Air conditioning system condensate
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 via SW -2 (see Attachment 7).
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.

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 MGD wastewater treatment facility.
Components of the treatment facility include a comminutor and manual bar screen, a submersible
pump station as an influent pump station, three treatment ponds, sand filtration, and chlorination
and dechlorination (or LTV disinfection). The pond treatment system consists of an aerated
pond with a minimum retention time of 10 days followed by a stabilization pond, also with a
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.
The sludge from the treatment facility will be land applied by a contractor (currently, Wallace
Woodall Vacuum Pumping, Inc., Permit No. WQ0000506, effective July 8, 1993, expiration
September 30, 1997) when necessary. 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 at 40 CFR Part 503.6.
DOMESTIC WASTE
The maximum domestic waste flow from the HE&EC sanitary facilities is approximately
0.014 MGD. In addition to the 235 permanent employees on 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).
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

ATTACHMENT 1B
PAGE 2 of 2
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 treatment ponds should ensure
that 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 to the effluent discharge line below the
sewage treatment plant and into Harris Lake, as allowed by radioactive materials License No. 092-
0218-4, issued by the N. C. Division of Radiation Protection.
Radiochemcial analyses are performed prior to release to calculate the total radioactivity in the
waste. These analyses include a gamma spectrum analysis using intrinsic germanium gamma
spectrometry systems, as well as direct analysis for Tritium, Iron -55, Nickel -63 and Strontium -89/90.
Individual radionuclides have different release limits; however, the total release for all radionuclides
may not exceed one curie per calendar year.
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 an additional sample is analyzed to verify that the appropriate
pH adjustment is achieved.
STORMWATER
Stormwater runoff from the HE&EC is composed only of parking lot, roof, and lawn drainage. This
non -industrial stormwater is not subject to the Phase 1 stormwater regulations at 40 CFR Part 122.

Outfall No. Description
SW -1 This outfall which discharges into the finger of the lake north of the
causeway receives input starting in the plant yard near the diesel fuel oil
storage tanks. It receives water from warehouse roof drains, paved and
gravel parking lots, and grassed areas before the outfall.
SW -2 This outfall which discharges into the finger of the lake north of the
causeway receives input starting in the plant yard under the plant output
transmission lines. It receives input from gravel parking lots and the normal
service water pump structure area before the outfall.
SW -3 This outfall which discharges into the finger of the lake north of the
causeway receives input from the first few SW -2 inputs as the two are cross
tied, the circulating pump intake structure area and paved parking lots before
the outfall.
SW -4 This outfall which discharges into the main intake canal at the emergency
service water intake structure receives input starting near the turbine building
and transformer area. It receives input from plant yard areas both paved and
gravel and paved parking lots before the outfall.
SW -5 This outfall discharges into a retention pond with an inverted siphon
discharge which travels along an open ditch, crosses a road and travels along
a gully before reaching the main lake. It starts at the northwest area of the
plant yard and receives input from plant roof drains Units 3 & 4 pit areas,
water treatment building, auxiliary boiler area, gas yard, neutralization and
settling basin areas, water treatment tank area, both gravel, paved and grass
plant yard areas, warehouse roof and drain area drains, and vehicle shop area
drains before the outfall.
SW -6 This outfall discharges into the emergency service water intake channel from
the auxiliary reservoir. It receives input from the gas yard, auxiliary boiler
fuel oil storage area, settling basin area, and gravel plant yard before entering
a ditch that travels to the outfall.
