Tennessee Valley Authority, Post Office Box 2000, Spring City, Tennessee 37381-2000 April 4, 2001 Mr. Philip Stewart, Manager Tennessee Department of Environment & Conservation Division of Water Pollution Control Environmental Assistance Center 540 McCallie Avenue, Suite 550 Chattanooga, Tennessee 37402-2013

Dear Mr. Stewart:

WATTS BAR NUCLEAR PLANT (WBN) - NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) PERMIT No. TN0020168 - APPLICATION FOR PERMIT RENEWAL Enclosed are one original and one copy of WBN's NPDES permit renewal application. The current WBN NPDES permit expires on September 28, 2001. WBN will continue to operate under the Tennessee Storm Water Multi-Sector Permit (TMSP No. TNR051343) For Industrial Activities. Because plant operations and discharges have not changed significantly, and the last EPA Form 2C submittal was less than three years ago; the same priority pollutant data is being re-submitted. However, the data from January 1998 through December 2000 from the Discharge Monitoring Reports has been updated. In addition, form 2C for outfall 113 data that was previously submitted to you in December of 2000 for discharge characterization, is being re-submitted with this package.

WBN requests changes to the chemical treatment programs for raw river water used in the plant and that thermal compliance monitoring be reduced to an end of pipe value for outfall 113. Changes in the raw water treatment program are necessary in order for WBN to address clam and mussel infestation issues in plant piping systems that are essential for the safe operation of the plant and to address biofouling of the cooling tower. The treatment program changes are detailed under the Raw Water Additives tab in the attached permit application.

The requested change in thermal compliance monitoring requiremenrs for outfall 113 is based on the studies conducted by WBN in accordance with the requirements in the current NPDES permit. These studies indicate there has been no impact to aquatic life by the operation of the SCCW system. Similarly, the thermal compliance data collected to date is sufficient to demonstrate by thermal modeling that an impact to aquatic life is not likely in the future.

Detailed justification for an end of pipe limit for outfall 113 will be forwarded under a separate cover letter pending analysis of the last thermal survey and final review of all thermal data collected to date on the SCCW system.

Cool

Mr. Philip Stewart, Manager Page 2 March 30, 2001 The only other significant change to this permit application from previous WBN applications is the flow diagram that accompanies the form 2C. At the request of the Chattanooga Field Office, an attempt was made to make the flow diagram more readable and supportive of the form 2C.

If you need additional copies or have comments or questions, please contact me at (423) 365-8005.

I certify under penalty of law that I have personally examined and am familiar with the information submitted in the attached document and based on my inquiry of those individuals immediately responsible for obtaining the information, I believe the submitted information is true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment.

WBN PROCESSES Chemicals Used in Plant Processes Chemical additives are used in plant processes and may be found in trace quantities in the various NPDES discharge points due to blowdown, leakage, and system maintenance activities. The following paragraph describes the most commonly used system additives. A table on the next page summarizes all chemical additives including the raw water additives that may be found in each outfall as well. The raw water additives are biocides and corrosion treatment chemicals and are discussed in more detail under the Raw Water Additives tab in this binder.

Hydrazine, ammonia, boric acid, sodium tetraborate, monoethanolamine, sodium molybdate, sodium tolyltriazole, potassium hydroxide, and lithium hydroxide are routinely added to the Primary and Secondary Systems to control pH and corrosion. Up to 300 pounds of modified alpha cellulose could be added to the condenser intake channel to temporarily plug pinhole tube leaks in the condenser. Hydrogen peroxide may be added during refueling for Primary System cleanup to reduce radiation exposure to maintenance personnel. Similarly, small quantities of ethylene glycol, a heat transfer medium used in building chiller packages, the ice condenser chiller packages, and diesel generators, could end up via leakage or maintenance activities in OSNs 101, 102, 103, and 107.

WBN PROCESSES

1. The Intake Pumping Station provides once through cooling water for the Raw Cooling Water and Essential Raw Cooling Water systems as well as water for most of the industrial processes at WBN. The IPS also is the primary source of water for the High Pressure Fire Protection System. The IPS is where most of the biocide and corrosion protection chemicals are added.

TNO020168 WBN PROCESSES 2C Flow Diagrams

2. Raw Water Chemical Additives are intended to prevent corrosion and protect plant systems from biological fouling and clam infestations. The additives and treatment programs are discussed in more detail under a separate tab. While there are some additions to discrete components in the plant, the majority of these products and treatments take place at the IPS. Bulk supplies are maintained near the IPS for controlled injection into either of the two IPS pits.

WBN PROCESSES

3. Supplemental Condenser Cooling Water is an additional supply of once through cooling water that gravity drains from above the Watts Bar Dam to help cool the main condensers. No chemicals are added to this water. However, upon return to the Unit One Cooling Tower Basin from the main condensers, SCCW water comes into contact with other once through cooling water from the IPS before returning to the river. The SCCW flows through the Unit Two Cooling Tower Basin, shown below, before entering the flume to the Main Condenser.

Tuesday, March 27, 2001 2C Flow Diagrams TNO020168 8

WBN PROCESSES

4. Once Through Cooling Water from the IPS supplies the many heat exchangers throughout the plant. Some of this water is discharged directly to the Turbine Building Station Sump. Some is discharged directly to the Yard Pond by storm drains. Leakage and maintenance activities could also see some of this water collected and processed through the Radwaste System as well. The majority of the water used in plant heat exchangers is then sent via a discharge header to the flume entering the main condensers from the Unit One Cooling Tower Basin to provide additional cooling for the main condensers and a source for the Recirculating Cooling Water System shown on page one of the Flow Diagram.

Tuesday, March 27, 2001 TNO020168 2C Flow Diagrams 9

WBN PROCESSES

5. Process Water refers to all the uses WBN makes of the river water collected at the IPS in order to generate power. Most of the processes require WBN to start by purifying the water to extremely pure levels then adding chemicals to meet the various system needs. As indicated in the form 2C application, most of these processes send wastewater to the TBSS or directly to the Low Volume Waste Treatment Pond. However, a small percentage do send wastewater directly to Cooling Tower Blow Down Line and the Yard Holding Pond.

Alum Ponds Vendor Water Purification Plant Tuesday, March 27, 2001 TNO020168 2C Flow Diagrams 10

WBN PROCESSES

6. Recirculating Cooling Water is ERCW and RCW water that is continuously cycled from the main condensers through the cooling towers to provide thermal transfer for the MAIN STEAM to CONDENSATE to FEEDWATER systems used to generate power.

Tuesday, March 27, 2001 TNO020168 2C Flow Diagrams I1I

WBN PROCESSES

7. The Low Volume Waste Treatment Pond is also referred to as the Low Volume Waste Holdup Pond in some correspondence. The majority of all NPDES Low Volume Waste is collected and treated here by sedimentation, oil skimming, and neutralization prior to discharge as an internal NPDES outfall to the Yard Holding Pond. This is OSN 103.

Tuesday, March 27, 2001 TNO020168 2C Flow Diagrams 12

WBN PROCESSES

8. The Lined Pond and the Unlined Pond are metal cleaning waste ponds.

These ponds are OSN 107. Physical or chemical cleaning processes potentially generating high levels of copper, iron or phosphorous are treated by sedimentation and neutralization prior to discharge.

Lined Pond Unlined Pond Tuesday, March 27, 2001 TNO020168 2C Flow Diagrams 13

WBN PROCESSES

9. The Yard Holding Pond receives once through cooling water as well as a small amount of low volume waste from system leakage and maintenance activities. The Yard Holding Pond is designed to provide oil skimming and sedimentation just like the Low Volume Waste Treatment Pond to ensure potential problems from plant processes are addressed prior to discharge. If required, neutralization could also be performed here.

Tuesday, March 27, 2001 2C Flow Diagrams TNO020168 14

WBN PROCESSES

10. The Cooling Tower Blowdown Line is that portion of piping between the CTBD Weirs and the "Y" where the Yard Holding Pond discharge joins to create the Diffuser Discharge Line. There are four sources of wastewater to the CTBD Line: the CTBD Weirs at the cooling tower basins; SGBD; the Condensate Demineralizer System; and the Radwaste System. Electronic interlocks prohibit discharges from the Radwaste System when there is less than 3500 cfs flow in the river. The Unit One Cooling Tower Blowdown Weir is shown below and is the major contributor to the CTBD line.

Tuesday, March 27, 2001 2C Flow Diagrams TNO020168 15

WBN PROCESSES

11. The Yard Holding Pond Overflow Weir Discharge point is rarely used. It is OSN 102 in the current NPDES permit and is considered an alternate discharge point for the Diffuser Discharge. When the diffusers are isolated, water routed via the CTBD Line backs up into the YHP.

When the level of the YHP reaches approximately 706.8 ft. above sea level, the pond begins to overflow across this weir. The effluent of the weir eventually enters the Tennessee River approximately 2500 feet downstream of the normal diffuser discharge point.

Tuesday, March 27, 2001 2C Flow Diagrams TNO020168 16

WBN PROCESSES

12. The Diffuser Discharge is OSN 101. The effluent from the YHP and CTBD Line merge into a single pipeline that later splits into two multiport diffuser legs that efficiently disperses the effluent in the Tennessee River.

Tuesday, March 27, 2001 TNO020168 2C Flow Diagrams 17

WBN PROCESSES

13. The Supplemental Condenser Cooling Water Discharge point is OSN 113. The energy dissipation structure and the 7 to 15 foot drop at the Glory Hole provide excellent aeration prior to discharging to the river.

A concrete ramp in the river diverts flow towards the surface to minimize thermal impact to any bottom dwelling aquatic life.

Tuesday, March 27, 2001 TNO020168 2C Flow Diagrams 18

14. The Sewage Treatment Plant is a 4 unit extended aeration facility.

WBN recently added UV disinfection capacity to improve reliability and minimize impact to the environment.

15. The Sewage Treatment Plant Discharge is OSN 111. This discharge point travels several hundred feet before emptying into the Construction Runoff Holding Pond.

Tuesday, March 27, 2001 2C Flow Diagrams TNO020168 20

WBN PROCESSES

16. The Construction Runoff Holding Pond is OSN 112. Storm water runoff is the major contributor by volume to this outfall. The CRHP discharges into an unnamed tributary which eventually empties into Yellow Creek.

Tuesday, March 27, 2001 TNO020168 2C Flow Diagrams 21

WBN PROCESSES

17. Cross Tie Control for OSN 113 is a valve that is used to ensure compliance with thermal limits. It allows WBN to control the amount of SCCW water introduced into the main condensers. A valve connecting the inlet and discharge lines is used to divert a portion of SCCW inlet flow directly to the discharge line.

Tuesday, March 27, 2001 2C Flow Diagrams TN0020168 22

WBN PROCESSES

18. The Turbine Building Station Sump is the primary collection point for system leaks, and low volume waste water at WBN. The TBSS provides oil skimming and some sedimentation treatment for the effluent. The TBSS effluent may be aligned to several discharge points to accommodate different plant conditions and needs. The normal alignment is to the Low Volume Waste Treatment Pond.

WBN PROCESSES 19.The Liquid Radwaste System is very sensitive to oil, grease, and suspended matter in the wastewater. A small amount will clog filters and render charcoal and demineralizer beds ineffective. The system will not remove radioactive contaminants if it becomes clogged with oil, grease or suspended matter. When radioactive contaminants are not removed, the system isolates automatically based on signals from the radiation monitor.

RAW WATER CHEMICAL ADDITIVES Inspection and chemical treatment programs have been implemented at Watts Bar Nuclear Plant to control fouling, plugging, and pipe wall thinning of the raw water systems. Most of these chemicals are added at the IPS to ensure all raw water systems are protected. Several of these systems, the High Pressure Fire Protection and the Essential Raw Cooling Water systems in particular, are essential for the safe operation of the plant. These programs provide for detection of microbiologically induced corrosion and clam or mussel infestations in the piping utilizing nondestructive examinations, leak detection, repairs, raw water sampling, and the addition of biocides and corrosion inhibitors.

This document is intended to be a comprehensive statement of the chemical treatments WBN proposes to use upon approval from the state to control corrosion and biological infestations. WBN proposes to show compliance with the methods below using mass balance calculations where possible. Detailed product information is included under the tab for that product at the end of this description of chemical treatments. A summary of the products to be used and their environmental impact is provided at the end of this document.

CARBON STEEL CORROSION INHIBITION WBN currently uses a combination of three chemicals to provide corrosion protection for plant piping. These chemicals are zinc sulfate (PCL-10Z), sodium pyrophosphate (PCL-60K) and a copolymer (PCL-401). WBN proposes changing from a zinc/pyrophosphate-based program (PCL-1 OZ & PCL-60K) to a zinc/orthophosphate-based program (MSW-109). MSW-109 contains 12.6% zinc chloride and 36 % orthophosphate. However, the concentration of zinc and phosphorous in the plant effluents will remain the same as our current program.

The zinc and the phosphorous levels will not exceed 0.2 ppm in plant effluents. It will still be necessary to maintain PCL-401 (copolymer) feed year round. Table I below details the proposed revisions to chemical feed.

TN0020168 Raw Water Chemical Additives WBN Permit Application RAW COOLING WATER BIOCIDE TREATMENTS Watts bar plans to continue the use, at our discretion, of the biopenetrant CL-363 and an oxidizing biocide in the raw cooling water. WBN is requesting with this permit application an increase in the CL-363 concentrations allowed and proposes to use an alternate oxidizing biocide.

CONVERSION FROM BCDMH TO TOWERBROM 960 Due to safety concerns about the loading of BCDMH (H-901 G), WBN proposes to use Towerbrom 960 as a direct replacement for the BCDMH. Towerbrom is safer to use because it is packaged to be replaced as a bin rather than as a bag of powder. Towerbrom 960 contains 89% Sodium Dichloro-S-Triazinetrione and 7%

Sodium Bromide. Towerbrom 960 dissolves to release bromine and chlorine much the same as BCDMH. It will be fed at the same frequency as the current BCDMH (approximately 4 to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> per day) with the same resulting TRO concentrations. If this change is acceptable, WBN will continue using BCDMH until design changes are implemented in the plant for a new feed system. The schedule of implementation is dependent upon state approval and the installation of the feed system.

To ensure complete halogenation of High Pressure Fire Protection systems necessary for plant safety, it will still be necessary to periodically perform periods of continuous bromination up to three times per year. These periods of continuous bromination will be a minimum of 21 day duration.

MOLLUSK CONTROL TREATMENT Due to an increase in the clam infestation seen in the plant piping necessary for safe shutdown of the plant, WBN proposes using the non-oxidizing biocide H 130M a minimum of 4 times per train per year. By treating train specific WBN will minimize the discharge level of H-130M to <0.10 ppm as active ingredient in plant effluents.

TN0020168 Raw Water Chemical Additives WBN Permit Application COOLING TOWER TREATMENTS WBN currently adds Towerbrom 960 to the cooling tower basin on a periodic basis for biological control. To enhance the effectiveness of this program, WBN proposes to use biopenetrant, CL-363, prior to halogenation. WBN proposes to begin feeding the CL-363 to enhance the oxidizing biocide effectiveness approximately 15 minutes prior to the Towerbrom addition. CL-363 is a 10%

solution of dimethylamide (DMAD). WBN will then add Towerbrom 960 directly to the basin. These chemicals will be added until a residual of 0.5 ppm TRO is achieved for 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> in the cooling tower basin. This treatment will be performed with the diffusers and SCCW isolated or, at WBN's discretion, WBN will de chlorinate as needed using sodium bisulfite solutions to ensure the current discharge limit of 0.1-ppm TRO is not exceeded at either OSN 101 (the Diffuser discharge) or OSN 113 (the SCCW discharge). Sodium bisulfite (Chlorakill 8816) will be ratio fed at a rate of 5 ppm product for every 1.0 ppm of TRO. The process will be controlled to ensure that the discharge concentration of TRO to the Tennessee River will never exceed 0.1 ppm and the discharge concentration of DMAD will never exceed 0.8 ppm as shown by calculation.

SM PRODUCT BULLETIN CL-363 Deposit Penetrant PRODUCT BENEFITS a Prevents Organic Deposit -

Oil, whether from a process leak or scrubbed from the atmosphere, can build up on system surfaces causing restricted water flow and loss of heat transfer, and it provides an ideal source of nutrient for biological growth.

CL-363 effectively penetrates and disperses these deposits.

• Improves Corrosion Inhibitor Performance Corrosion control of cooling water systems is based on forming a passivating film on the metal surfaces.

When these surfaces are fouled, treatment is often incomplete. CL-363 keeps metal surfaces clean, thus allowing a more uniform film formation and improved corrosion control.

GENERAL DESCRIPTION CL-363 deposit penetrant is a specially formulated liquid organic dispersant used to prevent and disperse biological and other organic deposits in cooling water and air washer systems. When added to the system, CL-363 increases the effectiveness of microbicides, enabling them to better penetrate and disperse the attached biomass. CL-363 is also effective in pen etrating and dispersing oil and other non-biological, organic deposits. For a general description of the typical chemical and physical properties, refer to the CL-363 Material Safety Data Sheet.

MATERIALS COMPATIBILITY Compatible materials of construction for bulk storage tanks include high density or cross-linked poly ethylene, 316 stainless steel, and epoxy phenolic lined steel, Compatible materials for pump "liquid ends" and piping include polyethylene, polypropylene, PVC, Kynar, 316 stainless steel, Hypalon, Teflon.

CONTROL TESTING Product performance Is ultimately confmrned by periodic equipment inspections, as well as heat transfer and corrosion monitoring.

FEEDING AND DOSAGE CL-363 should be fed directly from the shipping container as received, minimizing operator involve ment. CL-363 should not be mixed with other water treatment chemicals prior to feeding. Feed rates for CL-363 will vary depending upon system operating parameters and the type of deposition. Your Nalco representative will assist you in determining optimum dosage, feed point, and duration of feed, (Continued on Reverse Side)

PRODUCT BULLETIN H-I 30M Molluscicide PRODUCT BENEFITS

" Achieves a 100% kill rate of adult, juvenile, and veliger forms of zebra mussels and Asiatic clams usually within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of the start of a treatment program.

" One to three 24-hour treatments per year are usually sufficient to avoid the problems associated with an uncontrolled mollusk infestation.

" Treatment of a plant's discharge with CA-35, a bentonite clay, effectively complexes with H-130M to eliminate toxicity to non-target organisms. The combined complex is not harmful to aquatic species or benthic organisms.

" Biodegradable at use concentrations, providing an environmentally acceptable treatment.

" Treatment dosages as low as 0.5-2.0 ppm of H-130M are sufficient for an effective treatment.

" H-130M is a non-oxidizing molluscicide meaning that H-130M is available for mollusk control rather than being consumed by organic or inorganic reducing substances in the cooling water.

" Addition to the cooling water does not depress the pH of the bulk water and does not form corrosive by-products as found with chlorination or bromination.

"* Corrosion of metal surfaces is not accelerated by biocide treatment.

DIRECTIONS FOR USE H-130M molluscicide is only sold as part of a com plete Nalco mollusk treatment application service.

This product is safe to the aquatic environment only if the treated water is properly deactivated prior to discharge. The method for using this product is restricted by environmental regulations. This product is not to be used without supervision from a Nalco representative.

MATERIALS COMPATIBILITY Compatible materials of construction for pump and piping include polypropylene, polyethylene, Hypalon, stainless steel, epoxy phenolic-lined steel, or isophthalic polyester resins.

CONTROL TESTING AND EFFLUENT TOXICITY TESTING H-130M residual is monitored throughout a plant system and prior to discharge using a test procedure sensitive down to 20 ppb. The biological toxicity of the effluent water generated during the treatment is veri fied to be safe through a composite water sample sent to an outside laboratory.

K,.t I

FEEDING AND DOSAGE H-130M is fed as close to the raw water inlet as possible without risking the release of the chemical into the environment. Treatment of a system with H-130M molluscicide typically includes a 24-hour feed period at 1.5 ppm to the inlet of the plant, maintaining a residual at the discharge of 0.5 ppm.

The rate of adsorption of the biocide on the target mollusks and thus, the kill rate, is temperature dependent. Actual treatment durations may vary from site to site dependent on water temperature and other site specific conditions.

DEACTIVATION REQUIREMENTS CA-35 is used to deactivate H-130M molluscicide in the plant water prior to discharge to the environment.

f-:-

typically 5 ppm of CA-35 for every I ppm of H-130M moliuz'.--_-.-

N PRODUCT BULLETIN Rev. 8/98 H-901G Microblocide DESCRIPTION Bulletin No. 00-67H3 Calgon H-901G Microbiocide is a chlorine/bromine donating organic compound in granular form, facilitating rapid delivery into the cooling system. H-901G is registered for use in once-through cooling water systems and air washers.

H-901G, when dissolved in water, releases powerful oxidizing hypohalous acids which are highly effective in preventing biomass fouling in once-through cooling water systems. H-901G also controls the growth of microorganisms In the bulk air-washer water and removes existing biofouling from system surfaces.

ADVANTAGES H-901G's granular form provides for rapid application to fouled systems, resulting in a "shock" treatment, quickly arresting biological activity.

H-901G effectively controls microorganisms in cooling water systems operating over a pH range of 6.0 to 9.0. The hypobromous acid formed when H-901G is dissolved in water is about four times more active in maintaining microbiological control at lower treatment levels than chlorine fed intermittenly alone.

H-901G provides broad spectrum control of slime-producing microorganisms such as bacteria, fungi, and algae in air washers systems.

Often, reliable microbiological control can be achieved with H-901G as a single microbiocide treatment program.

H-901G remains active in the presence of ammonia.

When ammonia is present in cooling waters, both chlorine and bromine will react with it to form haloamines.

The chloramines formed are less effective biocides.

However, bromines have relatively the same biological effectiveness as hypobromous acid.

H-901G releases balanced amounts of residual hypobromous and hypochlorous acid.

Lower total free halogens are required to maintain microbiological control than when chlorine alone is used. Less free halogen is available to cause wood delignification or contribute to corrosion of system metallurgy.

H-901G is supplied as a granular solid.

It eliminates the need for gas chlorination equipment, handling gas cylinders, or feeding liquid hypochlorite. Since there Is no gaseous chlorine to escape to the atmosphere, and no liquid that could be spilled accidentally, the product Is safer to store and feed than gaseous chlorine or liquid hypochlorite products.

H-901G Bulletin No. 00-67H3 Page 2 EPA REGISTRATIONIUSDA APPROVAL H-901G is registered by the United States Environmental Protection Agency as a biocide for use in industrial, once-through cooling water systems (both fresh and seawater); cooling ponds and lagoons; influent water systems (e.g., flow-through filters, lagoons, etc.); heat exchange water systems; industrial, water-scrubbing systems; brewery and canning pasteurizers; and industrial air washing systems equipped with a mist eliminator. EPA Registration No. 8622-29-10445.

DIRECTIONS FOR USE Badly fouled systems must be cleaned before treatment is begun.

METHOD OF FEEDING H-901 G is dissolved and slug fed to the system using a brominator, a corrosion resistant polyester feed system, specially designed for the use of granular hydantoin-based microbiocides.

Your Calgon representative will determine the proper size feed system to meet your specific needs.

FEED RATES Initial Dose: When the system is noticeably fouled, add 0.2-0.6 pounds per 1000 gallons of water contained in the system.

A PRODUCT BULLETIN PCL-401 Scale Inhibitor PRODUCT BENEFITS Prevents the Formation of Calcium Phosphate

-Scale inhibition under severe conditions of calcium phosphate supersaturation is cost effectively attainable with TRC-233. The deposi tion of calcium phosphate scale from orthophos phate present in the cooling water system, either as the result of the inorganic phosphate corrosion control practice or from orthophosphate in the make-up, is effectively controlled by a threshold mechanism. Control of calcium phosphate is achieved without the need for costly pretreatment, undesirable pH depression and excessive blowdown.

Inhibits Scale Formation in High pH/Alkalinity Water -

Formulated to control potential scaling problems with calcium phosphate and low to moderate degrees of calcium carbonate super saturation scaling. Typical acid feed rates are greatly reduced, and in many systems, acid feed may be eliminated entirely.

Complements Good Corrosion and Biological Control -

For systems in which zinc is still permissible for use as a corrosion inhibitor, PCL-401 can be used to complement heavy metal corrosion control programs without pH control.

Deposits provide media for the propagation of biological growth and cause localized corrosion of metal surfaces. PCL-401 prevents the formation of deposits and disperses suspended solids. Cleaner surfaces deter further biological growth and assure better performance of corrosion inhibitors.

Iron Oxide Deposit Control -

Functions as a dispersant keeping metal oxides and silts fluidized, minimizing deposition in equipment and on heat exchanger surfaces.

" Stable In Chlorinated Water -

There is no need to increase dosage during periods of chlorination.

" Contains No Heavy Metals -

Contains no zinc or chromate. It can be used in systems where current discharge regulations prohibit the use of heavy metals.

" Convenient to Use -

Supplied as a liquid and can be fed directly from the shipping container or bulk storage tank. The need and associated costs for premixing chemicals is eliminated.

GENERAL DESCRIPTION PCL-40 1, based on pHreeGUARD technology, is a liquid product formulated to control the deposition of calcium scales in once-through and recirculating cooling water systems. The product contains the copolymer TRC-233. It is particularly effective for controlling the precipitation of calcium phosphate.

PCL-401 is a dispersant for suspended material such as silt and metal oxides. This dispersant action maintains the insoluble material in suspension, facilitating its removal from the system. For a general description of the typical chemical and physical properties, see the PCL-401 Material Safety Data Sheet.

PATENTS These products are covered under U.S. Patents 4,552,665 and 3,709,816.

A PRODUCT BULLETIN Towerbrom 960 Microbicide EPA Registration No: 935-71-1706 PRODUCT BENEFITS Supplied as a granular solid, Towerbrom 960 eliminates the need for gas chlorination equipment, handling gas cylinders, or feeding liquid hypo chlorite. There is no gaseous chlorine to escape to the atmosphere and no liquid which could leak.

• Provides broad spectrum control of slime producing microorganisms such as bacteria, fungi, and algae in industrial cooling water systems.

Often, reliable microbiological control can be achieved in a single microbicide treatment program.

• Easily fed over a broad range of dosages Effective in the presence of ammonia. Both chlorine and bromine will react with ammonia to form haloamines. However, chloramines are ineffective biocides while bromamines have relatively the same biocidal effectiveness as hypobromous acid. Towerbrom 960 systems are kept clean with minimum chemical usage and operator supervision.

• Effectively controls microorganisms in cooling water systems operating over a pH range of 6.0-9.5.

MATERIALS COMPATIBILITY Towerbrom 960 or a solution of Towerbrom 960 is a strong oxidizer. Do not mix directly with reducing agents, other oxidants or organic materials.

Compatible materials of construction for piping include C PVC, CPVC, Kynar, Viton A and acrylic.

GENERAL DESCRIPTION Towerbrom 960 Microbicide is a high performance, sodium dichloro-s-triazinetrione/sodium bromide compo sition, in granular form, for use in industrial cooling water systems. When dissolved in water, Towerbrom 960 forms oxidizing hypochlorous and hypobromous acids which are highly effective in controlling organic slimes of algae, bacteria and fungi. For a general description of the chemical and physical properties, refer to the Towerbrom 960 Material Safety Data Sheet.

CONTROL TESTING The best indication of the successful application of Towerbrom 960 is visual inspection of system surfaces, or monitoring changes in heat transfer on metal sur faces or process equipment. Usually a free oxidant residual is required to achieve biological control. Use of on-site bacterial count or microscopic examinations provide relative indicators of system cleanliness and biological control. If bacteria counts are used, note that counts may be high immediately after biocide addition.

Counts will decrease as control is achieved.

Towerbrom 960 Section 11. TOXICOLOGICAL INFORMATION ON PRODUCT:

Product Oral LDso (rat): 1350 mg/kg (similar formulation)

Product Dermal LD0o (rabbit): > 5000 mg/kg (similar formulation)

Toxicological data on oral effects: Following repeated exposure (8-weeks) to sodium dichloro-s-triazinetrione In their drinking water, rats demonstrated decreases in body weight gain, and drinking water consumption and changes in urine composition at dose levels of 4000 and 8000 ppm which produced some deaths. In a 90-day feeding study with rats, the two highest dose levels of 6000 and 12,000 ppm caused increases of the relative kidney and liver weights.

No birth defects were noted in rats given sodium dichloro-s-triazinetrione orally during the pregnancy, even at amounts which produced adverse effects on the mothers.

Toxic effects reported following ingestion of large single doses of bromide include stomach irritation, nausea, vomiting, and lethargy. Repeated ingestion of sodium bromide produces sedation and central nervous system (CNS) depression with possible effects such as headache, irritability, vertigo, memory loss, muscular incoordination, increased action of the reflexes, decreased appetite, hallucinations, acne-like rash, stupor and coma.

Following repeated exposures (4-12 weeks) to sodium bromide in their feed, signs of muscular incoordination and depressed grooming, changes in body weight and behavior, and endocrine (hormone) system effects were reported in laboratory animals. Reduced fertility and viability of offspring were noted in rats fed sodium bromide for three successive generations. These effects on the ability of rats to reproduce were reported to be reversible upon withdrawal of the bromide. Results of another study suggest that learning ability was reduced in offspring of rats given sodium bromide during pregnancy.

Toxicological data on inhalation effects: Signs of eye and nose irritation and changes in body weight, liver weight and blood cell composition were noted following repeated inhalation (4-weeks) of sodium dichloro-s-triazinetrione dust by rats.

TOXICOLOGICAL INFORMATION Toxicological data on chronic effects:

Little information is available about the health significance of low-level chronic sulfite exposure (including production within the body), but sulfite and bisulfite react irreversibly through free radical formation and otherwise with various substances in the body including DNA. Sodium sulfite has been demonstrated to be mutagenic in microbial systems; however, it is not mutagenic in studies involving insects and is not considered to present a mutagenic threat to humans.
