Dear Ms. Myers,
SEQUOYAH NUCLEAR PLANT (SON) - NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) PERMIT NO. TN0026450 - ADDITION OF SODIUM HYPOCHLORITE (LIQUID BLEACH) TO THE BIOCIDE/CORROSION TREATMENT PLAN Sequoyah Nuclear Plant (SON) plans to add Sodium Hypochlorite (liquid bleach) to our BiocidelCorrosion Treatment Plan. This addition is considered a significant change by SQN due to the fact that Sodium Hypochlorite would be injected continuously into the ERCW and RCW systems. All relevant information (frequency of discharge, active ingredients, discharge concentration, maximum daily usage, MSDS, product bulletin, etc.) on Sodium Hypochlorite is attached. Since, SQN considers this a significant change to the BICTP SQN is requesting approval prior to our initiation. SQN would like to begin the modifications to existing feed systems to apply this treatment March 30, 2007, so we are requesting approval by March 23, 2007.
If you need additional information or have comments or questions, please contact Ann Hurt (423-843-6714) or myself (423-843-6700).
/ certify under penalty of law that this document and all of its attachments were prepared under my direction or my supervisor in accordance with a system designed to assure qualified personnel properly gathered and evaluated 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.

- 3. Based on annual biological assessments and periodic toxicity testing, permit limitations of 0. 10 total residual chlorine have been sufficient to ensure that chronic and acute toxicity concerns are being addressed for oxidizing biocides. It is widely accepted that WET methods are not reliable for assessing toxicity elicited by chlorine since residual chlorine degrades rapidly during sample holding periods and -under ambient laboratory testing conditions. The toxicity values presented here Were derived from tests that mieasured chlorine toxicity in freshly-prepared solutions in the laboratory and are therefore overly-conservative.

TNO026450 TN0026450RATIONALE for Raw Water Chemical AdditivesSQ SQN Sodium Hypochiorite (Liquid Bleach)
The bleach solution is 12.5% active NaOCI producing 10.2% available chlorine. SQN proposes to utilize Sodium Hypochlorite for the routine continuous treatment of the plant's ERCW and ROW piping..
Effluents will be dechlorinated should in-plant targets threaten discharge limitations for chlorine. When dechlorinating, confirmatory samples will be collected during each day of treatment and analyzed according to NPDES permit requirements to ensure discharge limitations are met. Total Residual Chlorine is monitored 5 days per week at Outfall 101 in accordance with NPDES permit requirements to ensure discharge limitations are met.

Product Bulletin Sodium Hypochiorite Cooling Water Biocide PRODUCT DESCRIPTION AND APPLICATION SODIUM HYPOCHLORITE is an aqueous 12.5% solution of sodium hypochlorite. It is one alternative to gaseous chlorine, intended for use in recirculating and once-through cooling water systems. It can be used alone or in conjunction with NALCO's ACTI-BROM or chlorine stabilizer technology. SODIUM HYPOCHLORITE represents a cost-effective way to eliminate gaseous chlorine. SODIUM HYPOCHLORITE is not potably approved.
PHYSICAL & CHEMICAL PROPERTIES These properties are typical. Refer to the Material Safety Data Sheet (MSDS) for most current data.

As with all biocides applied in the United States, SODIUM HYPOCHLORITE is regulated by the U.S. EPA under The Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). It is a violation of federal law to use this product or any biocide in a manner inconsistent with its product label.
MATERIALS OF COMPATIBILITY Compatible Not Compatible EPDM Aluminurn Buna-N Brass Hypalon Carbon Steel Neoprene Nickel Polyethylene Polypropylene Titanium Polyurethane Vinyl Stainless Steel 304 PVC Stainless Steel 316 Teflon Viton DOSAGE AND FEEDING DIRECTIONS FOR USE IN ALL REGISTERED APPLICATIONS For the control of bacteria, algae, and fungi, add this sodium hypochlorite solution to-the tower basin, distribution box or some other point to ensure uniform mixing. Doses provided below should be considered starting points. It may be necessary to increase the dosage if measured halogen residuals are lower than those allowed by the product label.
A. SLUG FEED METHOD Initial Dose: When the system is noticeably fouled, add appropriate amount of SODIUM HYPOCHLORITE per 10,000 gallons of water in the system to obtain from 5 to 10 ppm available chlorine.
Repeat until control is achieved. Badly fouled systems must be cleaned before treatment is begun.
Subsequent Dose: When microbial control is evident, add appropriate amount of SODIUM HYPOCHLORITE per 10,000 gallons of water in the system daily, or as needed to maintain control and keep the chlorine residual at 1 ppm.
B. INTERMITTENT FEED METHOD Initial Dose: When the system is noticeably fouled, add appropriate amount of SODIUM HYPOCHLORITE per 10,000 gallons of water in the system to obtain from 5 to 10 ppm available chlorine.
Apply half (or 1/3, 1/4, or 1/5) of this initial dose when half (or 1/3, 1/4, or 1/5) of the water in the system has been lost by blowdown. Badly fouled systems must be cleaned before treatment is begun.
Subsequent Dose: When microbial control is evident, add appropriate amount of SODIUM HYPOCHLORITE per 10,000 gallons of water in the system to obtain a 1.0 ppmn residual. Apply half (or 1/3, 1/4, or 1/5) of this initial dose when half (or 1/3, 1/4, or 1/5) of the water in the system has been lost by blowdown.
C. CONTINUOUS FEED METHOD Initial Dose: When the system is noticeably fouled, add appropriate amount of SODIUM HYPOCHLORITE per 10,000 gallons of water in the system to obtain from 5 to 10 ppm available chlorine.
Badly fouled systems must be cleaned before treatment is begun.
Subsequent Dose: Maintain this treatment level by starting a continuous feed of 1 ounce of SODIUM HYPOCHLORITE per 1,000 gallons of water lost by blowdown to maintain a 1.0 ppm residual.
ENVIRONMENTAL AND TOXICITY DATA Biological Oxygen Demand (5-day BODO) 0 Chemical Oxygen Demand (COD) 0 Total Organic Carbon (TOC) 0 Refer to the product's Material Safety Data Sheet SECTIONS 11 and 12, for all aquatic and mammalian toxicity information.
SAFETY AND HANDLING Please read the Material Safety Data Sheet before using this product.
