Renewal Application Amendment —Attachment No. 5 Modification
Dear Ms. Rodriquez:
Duke Energy Progress, LLC submitted the subject renewal application package on May 26,
2016 which was received in your office on June 1, 2016. By submittal of this letter, Duke
Energy Progress, LLC is hereby amending the subject current NPDES permit application.
During a recent review and discussions regarding biocidal additives with our water treatment
vendor (Nalco), we were informed that two (2) of the previous biocides were no longer being
manufactured in the same formulation (dispersant modifications). All other components of the
products are the same. As a result, we need to substitute the following biocides for our water
treatment regimen:
Previous Product
Nalco 3D Trasar 3DT294
Nalco 3D Trasar 3DT304
New Product
Nalco 3D Trasar 3DT494
Nalco 3D Trasar 3DT404
Another change we are incorporating is the use of Nalco 90005 for water treatment
management of our cooling towers.
An updated Attachment 5 of EPA Form 2C — Item VI "Potential Discharges Not Covered By
Analysis" and the Safety Data Sheets for these products are attached. We do not anticipate any
permit modification being necessary as a result of this modification of our NPDES application.
We will gladly assist should additional questions arise. Copies of the SDS and completed
biocide worksheets are also being sent to the Aquatic Toxicology Branch of NC DEQ DWR. If
you have any questions regarding the enclosed information, please contact Mr. Marty McGowan
at [phone] or Mr. Don Safrit, at [phone].

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.
I. Facility Name Brunswick Steam Electric Plant (BSEP)
NPDES # NC0007064 Outfall # 001
County Brunswick
Receiving Stream Atlantic Ocean 7Q10 NA (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 body?
A.D.D. = 1296 (in M.G.D.)
Please calculate the lnstream Waste Concentration (IWC in percent) of this discharge using the data entered
above.
IWC = 1296 x 100 = 100%
(NA) (0.646) + 1296
This value (IWC) represents the waste concentration to the receiving stream during low flow conditions.
11. What is the name of the whole product chemical treatment proposed for use in the discharge identified in Part 1?
Nalco Trasar SDT494
Please list the active ingredients and percent composition:
Sulfuric Acid 1-5%
Benzotriazole 1-5%
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.= 8.000 grams/24hr period
Please note, fluid ounces (a volume) must be converted to grams (a mass). 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 453.59%
128 fl. oz. 1 gal. water 1 Ib.

Facility Name: Duke Energy Progress, LLC — Brunswick Steam Electric Plant NPDES M NC0007064
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= 569 million gallons
What is the pH of the handling system prior to biocide addition? If unknown, enter N/A. NA
What is the decay rate (D.K.) of the product? 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. = Days
The decay rate is equal to HIL X 0.69 = =Decay Rate (D.K.)
Calculate degradation factor (D.F.). This is the first order loss coefficient.
* D.F. = A( D.D.) (Volume) + (D.K.) = 1296/569 + 0 = 2.278
Calculate Steady State Discharge Concentration:
Dischg Conc. _ (D.R.) _ (8000)/[(2.278)(569)(3785)]= 0.00163 mg/I
(D. F.) (Volume) (3785)

Choose the lowest LC50/EC50 listed above:
Enter the LC50/EC50: 3409
If the half life (H.L.) is less than 4 days, perform the following calculation.
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 = 34.09 mg/I
Choose the appropriate regulated limitation from the calculations immediately above and place in this blank:
34.09 mg/liter
From Part II enter the receiving stream concentration:
0.00163 mg/liter
IV. Analysis. PASS
If the receiving stream concentration is greater than the calculated regulated limitation, then this biocide is
unacceptable for use.

If copper, zinc, or chromium are present in the proposed biocidal compound, complete this worksheet. A separate form
must be used for each metal and/or metal compound present in the biocide. List the metal, its chemical formula, molecular
weight (MW), formula weight (FW), and the concentration of the metal compound in the biocide (MCC). Complete a
separate form for every metal present in the biocide.

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.

What is the Average Daily Discharge (A.D.D.) volume of the water handling systems to the receiving water body?
A.D.D. = 1296 (in M.G.D )
Please calculate the Instream Waste Concentration (IWC in percent) of this discharge using the data entered
above.
