NPDES Notification of Biocide Change
Dear Ms. Grzyb:
Duke Energy Progress, LLC (Duke Energy), is hereby notifying the North Carolina Department
of Environmental Quality (NCDEQ) of its intent to include an additional biocide, chlorine dioxide,
to the list of chemicals used at the Shearon Harris Nuclear Power Plant (HNP) provided in the
National Pollution Discharge Elimination System (NPDES) Permit No. NC0039586.
Chlorine dioxide, a product of the Nalco Purate system, will be the main biocide used at HNP in
treating the cooling tower basin and open cooling water sources. Sodium hypochlorite will still
be used for water treatment in addition to the chlorine dioxide, and will provide an emergency
source of biocide treatment.
The Biocide/Chemical Treatment Worksheet -Form 101, a map indicating discharge point and
receiving stream, an ECOTOX Aquatic Report for chlorine dioxide, and the Safety Data Sheet
for Purate (proprietary reactant to generate chlorine dioxide) are included as enclosures to this
letter for your files. Please note that dechlorination is provided on the cooling water stream
following the chlorination process, prior to discharge to the combined discharge to Harris
Reservoir (Outfall 006) Due to this additional dechlorination process, Duke Energy believes
Purate and its generated product, chlorine dioxide, are acceptable for use
If there are any questions regarding the enclosed information, please contact Mr. Don Safrit at
[phone].
l 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.

BIOCIDE/CHEMICAL TREATMENT
WORKSHEET -FORM 101
The following calculations are to be performed on any biocidal products ultimately discharged to the surface waters of
North Carolina This worksheet must be completed separately for each biocidal product in use This worksheet is to be
returned with all appropriate data entered into the designated areas with calculations performed as indicated
Facility Name Harris Nuclear Plant
NPDES # NC 0039586
Outfall # 001
County Wake County
Receiving Stream Harris Lake 7Q10 N/A (cfs)
(All above information supplied by the Division of Water Quality)
What is the Average Daily Discharge (A D D ) volume of the water handling systems to the receiving water body9
ADD =16 (in M.G.D )
Please calculate the Instream Waste Concentration (IWC in percent) of this discharge using the data entered
above
IWC = (A.D.D.) X 100 = (16mgd) x (100) / (0) + (16mgd) = 100
(7Q 10) (0.646) + (A. D. D)
7Q 10 = 0 for Hams Lake"
This value (IWC) represents the waste concentration to the receiving stream during low flow conditions
II What is the name of the whole product chemical treatment proposed for use in the discharge identified in Part I?
Chlorine Dioxide
Please list the active ingredients and percent composition -
Chlorine Dioxide
100 %
What feed or dosage rate (D R ) is used in this application? The units must be converted to maximum grams
of whole product used in a 24hr period
D R = 121,090 grams/24hr period
Please note, fluid ounces (a volume) must be converted to grams (amass) The formula for this conversion is
Grams of product = fluid oz. of product X 1 gal water X 8 34 lbs. X specific gravity of product X 453 59g
128 fl oz 1 gal. water 1 Ib.

Facility Name Harris Nuclear Plant NPDES #. NC 0039586
Estimate total volume of the water handling system between entry of biocidal product and NPDES discharge point
On an attached sheet please provide justification for this estimate (system volume, average cycles per blowdown,
holding lagoon size, etc )
Volume= 7 0 million gallons
What is the pH of the handling system prior to biocide addition? If unknown, enter N/A 80
What is the decay rate (D K) of the product9 If unknown, assume no decay (D K.=O) and proceed to asterisk.
The degradation must be stated at pH level within 1/2 pH standard unit within handling system Enter the half life
(Half Life is the time required for the initial product to degrade to half of its original concentration) Please provide
copies of the sources of this data
H L = Unknown Days
The decay rate is equal to H1L X 0 69 = 0 =Decay Rate (D K)
Calculate degradation factor (D F ) This is the first order loss coefficient
*D F = (A ( D De) + (D.K) _ ((16 mgd)/7 million gal) + 0) = 228
Calculate Steady State Discharge Concentration*
Dischg Conc— (D R ) _ [121,0901/[(2.28)(7.0)(3785)1= 200 mg/I
— (D F )(Volume)(3785)
Calculate concentration of biocide instream during low flow conditions.
(Receiving Stream Concentration)
(Dischq Conc) x (IWC%) _ [(2.0)(100%)1/100 = 2 00 mg/I

III Calculate regulated limitation
List all LC50 and EC50 data available for the whole product according to the following columns (Note that units
should be in mg/1) Please provide copies of the sources of this data
Organism Test Duration LC50/EC50 (mg/1)
Pimephales promelas 96hr 0 02/N/A
Daphnia Pulex 48hr N/A/1 8
Pimephales promelas 96hr 0 17/N/A
D W Q Form 101 (6/2000) 2

Facility Name Harris Nuclear Plant NPDES # NC 0039586
Choose the lowest LC50/EC50 listed above
Enter the LC50/EC50 0.02/1 8
If the half life (H L ) is less than 4 days, perform the following calculation H.L for C102 is unknown In this
application.
Regulated Limitation = 0 05 x LC50 = mg/I
If the half life (H L ) is greater than or equal to 4 days or unknown, perform the following calculation
Regulated Limitation = 0 01 x LC50 = 00002 mg/I
Choose the appropriate regulated limitation from the calculations immediately above and place in this blank
00002 mg/liter
From Part II enter the receiving stream concentration
20 mg/liter
IV Analysis
If the receiving stream concentration is greater than the calculated regulated limitation, then this biocide is
unacceptable for use Fail however, please note that cooling tower blowdown stream (Internal Outfall 001)
receives dechlorination treatment prior to discharge to combined discharge to Harris Reservoir (Outfall 006)

listed in sections 7 and 8. Drying of this product on clothing or
combustible materials may cause fire.
Environmental precautions
Do not allow contact with soil, surface or ground water.
Methods and materials for Stop leak if safe to do so. Contain spillage, and then collect with
containment and cleaning up non-combustible absorbent material, (e.g. sand, earth,
diatomaceous earth, vermiculite) and place in container for disposal
according to local / national regulations (see section 13). Flush away
traces with water. For large spills, dike spilled material or otherwise
contain material to ensure runoff does not reach a waterway.
SECTION 7. HANDLING AND STORAGE
Advice on safe handling Do not breathe dust/fume/gas/mist/vapours/spray. Do not get in
eyes, on skin, or on clothing. Wash hands thoroughly after handling.
Use only with adequate ventilation. Do not mix with bleach or other
chlorinated products — will cause chlorine gas. Drying of this product
on clothing or combustible materials may cause fire.
Conditions for safe storage Keep in a cool, well -ventilated place. Keep away from reducing
agents. Keep away from combustible material. Keep out of reach of
children. Keep container tightly closed. Store in suitable labeled
containers.

Mobility
The environmental fate was estimated using a level III fugacity model embedded in the EPI (estimation
program interface) Suite TM, provided by the US EPA. The model assumes a steady state condition
between the total input and output. The level III model does not require equilibrium between the
defined media. The information provided is intended to give the user a general estimate of the
environmental fate of this product under the defined conditions of the models.
If released into the environment this material is expected to distribute to the air, water and
soil/sediment in the approximate respective percentages;
Air <5%
Water 30 - 50%
Soil 50- 70%
The portion in water is expected to be soluble or dispersible.
