Catawba Nuclear Station -NPDES Permit No. SC0004278 Sodium Bromide Request for Permanent Approt .
File: CN-702.13
Dear Mr. Eleazer:
This letter is being written to request that Mium bromide be approved as a permanent treatment compound for the control of algae in the cooling towers at Catawba Nuclear station. As you may recall, Catawba has been using this compound on a temporary basis in order to determine the effectiveness of its use. The use of sodium bromide will allow the station to reduce the total amount of treatment chemicals used.
In your letter dated September 15,1994, you stated that before sodium bromide can be used permanently as a maintenance chemical in the cooling towers, the NPDES permit will have to be modified to add Free Available Oxidant (FAO) to the permit.
We would like to propose that Free Available Chlorine (FAC) continue to be listed on the NPDES permit and that the permit not be modified until the next permit renewal. The actual analytical method will be unchanged regardless of whether the analysis is reported as FAC or FAO. Both sodium hypochlorite and sodium bromide are oxidants. Since sodium hypochlorite has historically been the only oxidant used, FAC has been more appropriate to report. Regardless of whether you report FAC or FAO the results are the same. The station monitors this outfall to ensure that the discharge is below permit limits prior to blowdown.

Catawba Nuclear Station Written Follow-up of Oil Sheen On Lake Wylie l File: CN-720.01 l h
! Dear Mr. Spigner i l t
This letter is to provide you written follow-up of our telephone conversation Friday, l
February 10,1995. As we discussed, a visible oil sheen was noticed in our intake cove
- directly below and around our intake structure the evening of February 9,1995.
A fire protection pipe on the intake structure burst and flowed water over the structure to l the lake unt.il it could be isolated. At the same time work was in progress on the structure l to remove an intake pump for repair. Residual oil from this operation was washed into the
- lake when the fire protection pipe burst. The amount of oil reaching the lake is estimated to be a pint.
As a preventative measure we use two oil booms in this area. One is located around the intake structure itself and the other is located further up the intake cove. The oil caused a l sheen on the lake which was contained within the boom system. Cleanup operations were l implemented using absorbent pads and pillows. Notifications were made as follows:
l l National Response Center - Mr. Chen - 7J9/95 @ 1830 l Nuclear Regulatory Commission - ML Rich Freudenberger - 2/9/95 @ l847.

Catawba Nuclear Site NPDES Permit #SC0004278 Unauthorized _ Discharge l File: CN-702.26 l
l .
Dear Mr. Robinson:
I l Per your request this memo is a follow-up report on the unauthorized discharge of cooling water l (via yard drain) to Lake Wylie that occurred on February 22 and 23,.1995 at Catawba Nuclear i
Station. There was no observed environmental impact during this discharge. This event will also ,
l be noted on the NPDES Discharge Monitoring Report pursuant to Part II. B. 3. of the subject l permit. .
! On February 22,1995, at approximately 4:30 p.m. water was observed to be seeping up from the l ground at the Unit 2 cooling tower yard area. The flowrate was visually estimated to be thirty to l fifty gallons per minute. Julie Lott of DHEC was notified via the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> notification line at 5:30 p.m. on February 22.
The syitem was last checked for chlorine content on Febmary 21,1995, by Enviror. mental Chemistry and none was detected. At the point of rupture, the water was sampled for dispersant
- levels and temperature on February 22,1995. It was found to contain 4 ppm of a dispersant l (used to keep solids suspended in solution). The chemical used was BL-7071 (Duke Power MSDS number 19502). The chemical is identified by the manufacturer as not containing any j SARA / CERCLA hazardous substances. The water contained no other chemicals. The temperature of the water was 72.5 degrees Fahrenheit.
l l
i
Page 2 o. .
. The actual release occurred due to a stress crack in an underground pipe that is used to transport the Unit 2 condenser cooling water to the Unit 2 cooling towers. The stress crack was caused when a drop in temperature of the cooling water occurred as Unit 2 came offline. Unit 2 came offline on February 21,1995 at 9:54 p.m. The flow was stopped by digging a pit to collect the water at 8:30 a.m. on February 23,1995. The water was pumped from this pit to the Unit 2 C cooling tower. It is estimated that between twenty-nine thousand seven-hundred (29,700) and forty-nine thousand five-hundred (49,500) gallons of RC water flowed to Lake Wylie between the time the leak was identified and when the flow was stopped.
The underground pipe has been repaired, the system has been returned to service, and Unit 2 will be returned to service soon. The root cause of the pipe failure and possible corrective actions are still underinvestigation.
l If you should have any questions concerning this matter or need additional information, please contact Joe Funderburk at (803) 831-3925 or Cheryl Peed at (803)831-3361.

j Per your request this letter will describe the discovery and corrective actions concernmg the discharge of Cooling Tower water thmugh a stormwater outfall, as reported to the Ft.
f Lawn office on March 21,1995. l l
On March 13, Catawba Site Environmental personnel discovered a steady flow of water from Stormwater Outfall #15 while performing an annual"non-stonnwater dischsge" assessment. Due to recent rain, it was unclear to the observers whether the origin of the water was stormwater, or some other source. On Marcli 20,. Stormwater Outfall #15 was revisited. The amount of flow was the same, although there had been no significant rain in the interim. Flowrate was measured to be 15 gpm. The morning of March 21, chlorine was added to the Unit 2 Cooling Towers. By aftemoon, chlorine was detectable at Stormwater Outfall #15. The Unit 2 Cooling Tower blowdown line was isolated, and .
How ceased at Stormwater Outfall #15. Environmental Management personnel noti 6ed the SCDHEC Ft. Lawn office that afternoon. '
l Excavation ensued to find and repair the cause of the leak. The root cause of the leak at i Stormwater Outfall #15 was discovered to be a through-hole in the Unit 2 Cooling Tower l blowdown line. The assumption is that it was caused by drilling through with a (
"Geoprobe" groundwater monitor. (Geoprobe drilling was performed in this area on !
12/15/94). Since the cooling tower blowdown line crosses over the stormwater line in the vicinity of the hole, it is assumed that the cooling tower water then " migrated" down the stormwater line ditch to the outfall. An additional" minor" leak was found at a vent pipe ;
flange, ma well as some "weepage" through the fiberglass pipe during pressure testing.
- By April 6, all leaks were repaired and the blowdown line was feturned to service.
l Mausd on sucycendasser
i There is no evidence that the leakage of the cooling tower water caused any adverse environmental impact. Samples taken the afternoon of March 21, downstream of Stormwater Outfall #15, as the water entered Lake Wylie, indicated no detectable ;
chlorine This was after the Unit 2 Cooling Tower water had been chlorinated that !
morning.
As a final note, while the problem at Stormwater Outfall #15 was being investigated, l leakage was also discovered at Stormwater Oufalls #17 and #18. We showed these to you during your visit on March 22.

i l
Dear Mr. Eleazer:
i I
Catawba Nuclear Station received approval to use the following additional treatment chemicals in a letter from DHEC dated March 15,1995 (copy attached):
i l
- 1. Carbohydrazide '
l- 2. NALCO DYNACOOL 1389 j 3. dibromo-3-nitrilopropioa*=W or DBNPA
] 4. 3-MPA or 3 methoxypropylamine 1
[j Upon review of this approval letter and the actual application of these compounds, we would like to request that the approval letter be modified and reissued. The reasons for this request
! are provided below: '
i e
The approval to use NALCO DYNACOOL 1389, DBNPA and 3-MPA provided an actual effluent limitation value which was based upon the anticipated discharge value and l not the aquatic toxicity of the compounds as provided in the MSDS sheets. The usage of i these compounds is well below the aquatic toxicity values. The anticipated discharge values were provided to show that the compounds would not be discharged in toxic concentrations.
l e
There does not exist a good analytical method to analyze for these compounds in low concentrations in a wastewater matrix. We can analyze for the compounds and come up
~ . - -
t with an actual number in a cleanwater sample and therefore know the concentrations of the chemicals which are being added to the systems. The anticipated discharge values \
~
shown in the request were calculated values. Therefore, we will not be able to demonstrate by analytical means what the actual concentration of the product is at the discharge point.
For these reasons we would like to request that the letter be revised to provide a simple !
approval to use the compounds as described in the permit application and that a numerical effluent value not be assigned for each compound. We will discharge at or below NOEC ,
concentrations for C. dubia. Our existing toxicity monitoring program will verify that these I compounds are not being discharged in toxic concentrations. Additional toxicity testing shall be performed if the NOEC limit is approached. j Upon review of the usage of the 3-MPA, we have reworked the typical discharge l concentration range to between 1 and 5 mg/l rather than 0.1 mg/l as shown in the application l submitted on February 15,1995. A revised copy of the proposed usage for this compound is (
attached for your review. The discharge concentration range of 1 to 5 mg/l is below the ;
NOEC value for this compound.
Should you have any questions concerning this letter please give John Estridge a call at (704) 875-5965.

l 1.0 GENERAL STATION DESCRIPTION The Catawba Nuclear Station is a two unit nuclear fission steam electric generating station. It is owned by Duke Po,wer Company, North Carolina Electric Membership Corporation, North Carolina Municipal Power Agency Number #1, Piedmont Municipal Power Agency, and.the Saluda River Electric Cooperative,
. ~Inc. The facility is operated by Duke Power Company.
Each unit is a four loop pressurized water reactor. Reactor fuel is zircaloy clad sintered uranium oxide pellets. Reactor heat from each unit is absorbed by the reactor coolant system and produces steam in four steam generators sufficient to j- drive a turbine generator unit with a design net electrical rating of 1129 L megawatts.
The nuclear reaction is controlled by control rods and chemical neutron
( absorption. Boric acid is used as a chemical neutron absorber and to provide l l borated water for safety injection. During reactor operation, changes are made in !
the reactor coolant boron concentration. l l
A schematic diagram of water use and discharges indicating average rates of flow for individual waste streams of Catawba Nuclear Station is attached. Actual flows through individual systems may vary significantly depending on need to operate )
and meteorological conditions. The following is a brief description of the major i discharges for the station. -
l The station has 5 permitted outfalls, three of which discharge directly ihto Lake !
Wylie. Outfall 001 discharges once through cooling water from the Low Pressure i Service water system. Outfall 002 discharges the Conventional Wastewater Treatment system which consists of station sumps and blowdown from various ;
plant systems. Outfall 003 discharges sanitary wastewater from the various buildings on site. Outfall 004 is an intemal outfall ' discharging low level :
radioactive effluents through outfall 001. Outfall 005 is also an internal outfall !
discharging cooling tower blowdown through outfall 001.
1 2.0 Station Intakes l
There are two intake structures to withdraw raw water from Lake Wylie. One for the Low Pressure Service Water System and one for the Nuclear Service Water System. The locations of the intake points and discharge location is shown on
- - Attachment #1.
'. i I
j Lake water enters each intake structure through trash racks. The trash racks l
remove large debris and then through traveling screens, which remove smaller l l debris.

i
. i e :
2.1 Low Pressure Service Water Intake Structure l
There are a total of six pumps on the Low Pressure Service Water intake l
structure. Three are for the Low Pressure Service Water System and three are for the Fire Protection System. Each Low Pressure Service Water pump is in a separate bay equipped with a trash rack and traveling icreen.
- The three fire protection system pumps share a single bay. The trash racks ,
and traveling screens remove trash and prevent debris from entering the I pumps.
Accumulated trash is cleaned from the racks by hand and from the screens by. a backwash system. The intake screens are backwashed manually, automatically, or as frequently as the differential level alarms on each pump bay indicate the need. Design flow is 560 gpm. Each screen is backwashed every eight hours for 45 minutes per screen. The water is returned to Lake Wylie at the intake bay. The trash and debris collected from the racks and screens are disposed in a permitted landfill. No chemicals are used in the backwash operation.
The three low pressure service water pumps are separated by precast i concrete wall panels that form pump wells. Each pump withdraws water '
from its well and discharges to a common-header. After leaving the common header, flow is divided into two main headers, A and B. Both i headers are in service during normal operations, however a single header - I can provide sufficient flow to meet system demands with both units in !
operation. .
1 Upon entering both headers A and B, flow passes through a'stramer designed to remove still finer debris from the lake water. These strainers backwash automatically based upon either a set time interval or increase in differential pressure. This backwash water passes through a strainer basket which catches the refuse and allows the water to drain back to the lake.
2.2 Nuclear Service Water System Intake Structure The Nuclear Service Water System is a once-through non-contact plant y cooling water system. This system supplies cooling water to various heat i
loads in the Auxiliary and Reactor Buildings other than the secondary (steam) side of the station. It is served by two bodies of water - Lake l l
Wylie and the Standby Nuclear Service Water Pond - but only one pump i f structure. The intake structure in each water body is completely i submerged approximately 30 feet below the surface of the water. Normal Cata vba Nuclear Station NPDES Permit SC0004278 Supplemental Information j Revised 7/18/95 Page5 '
l
alignment is from Lake Wylie with the Standby Nuclear Service Water Pond as an assured back-up in case oflow level in the pump structure.
The Standby Nuclear Service Water Pond (SNSWP) and the pump structure are seismically designed with sufficient water to bring the station to a cold shutdown in case of the loss of Lake Wylie Dam. The level of
' the pond is maintained via an overflow pipe to the lake and pumping capability from the lake. Water from either the pond or the lake is piped to the nuclear service water pump structure. The pump structure consists of two 330,000 gallon pits that serve to provide suction to the pumps. There are two pumps per pit for a total of four pumps inside the intake structure.
l In normal Nuclear Service Water System operation, pump suction is from Lake Wylie. Pump suction can be switched to the Standby Nuclear Service Water Pond.
Additionally, during testing required by the Nuclear Regulatory Commission, in order to verify flow balance, and certain times during plant operation the Nuclear Service Water system is aligned to discharge to the Standby Nuclear Service Water Pond rather than outfall 001. When discharge is aligned in this manner, the pump suction can be either from the lake or the pond.
In order to maintain the temperature of the SNSWP within limits imposed by the Nuclear Regulatory Commission cooler water from Lake Wylie is
~
periodically pumped to the pond. This is dependent on current weather conditions and the amount of time in such alignment will vary.
The typical temperature change of the water removed from and returned to the Standby Nuclear Service Water Pond is 2 0F. The temperature change is greater if alignment to the pond occurs during the process of shutdown. This alignment may also be required periodically during times when a diesel generator is inoperable. The discharge line to the pond splits and discharges flow to separate points of the pond to assure that cooling will be uniform across the surface.
Periodically to ensure operability, the nuclear service water pump bearings are cleaned to remove silt and sediment deposits which restrict pump cooling water flow. Approximately fifty gallons of cleaning i
solution are injected into the bearing cooling water flow path for each pump. A soda ash (Na2CO3 ) solution is used for rinsing the pump bearings. The cleaning solutions are captured in drums and are used as treatment chemicals in the conventional treatment ponds. This cleaning is Catawba Nuclear Station NPDES Permit SC0004278 Supplemental Information Revised 7/18/95 Page 6 l

Liquid Radioactive Waste (WL) Outfall 004 Cooling Tower Blowdown (RC) Outfall 005 l Nuclear Service Water System (RN). j
! 1 l A detailed description of each input follows.
l I
3.1.1 Low Pressure Service Water The Low Pressure Service Water System supplies raw water from Lake Wylie for makeup and cooling of various secondary plant l systems. This system also receives discharges from the Nuclear l l Service Water System, Liquid Radwaste System (Outfall 004), and l l Cooling Tower Blowdown (Outfall 005).
- As a result of macroinvertebrates (Corbicula
- Asiatic clams) and l microbiologically influenced corrosion (MIC), chemical addition l is anticipated. Presently, flushing is the control method used to l control the growth of the clams, however, chemical addition is l anticipated to become necessary.
L Chemicals anticipated to be added to control Corbicula and MIC include chlorine, biocides, dispersants, and corrosion inhibitors that include nitrite, silicates, molybdates, phosphates, polyphosphates, and borates. Chlorine addition at a level necessary j to maintain a low level discharge concentration of total residual chlorine (TRC) is under evaluation. Discharges to Lake Wylie would be maintained at an approved discharge concentration i

3.1.2 Liquid Radioactive Waste - Outfall 004 l
Outfall 004 discharges flow.,from the liquid radwaste system. This flow combines with plant once through cooling water,before discharging through outfall 001. -
. l The liquid radwaste system collects waste floor and equipment drains, laundry waste, and ventilation unit drains. All waste is processed to Nuclear Regulatory Commission (NRC' equirements l
' (10 CFR Part 20 and 10 CFR Part 50) prior to rewe with the type of processing depending on the type of waste. T1.e maximum ;
discharge rate from radwaste is 250 gpm. Chemicals that may be I present in ti:e liquid radwaste system include:
Outfall 004 Inputs I boric acid borax nitrate ammonia morpholine lithium hydroxide
! ethylene glycol benzotriazole(BZT) nitrite / borax corrosion inhibitor nitrite / molybdate hy& azine !
l corrosion inhibitor carbohydrazine chlorine or hydrogen peroxide hypochlorite ethylene diamine 3-mpa organic -
l tetracetic acid phosphonates used (EDTA) in heat exchanger lay-up r
pump bearing laboratory surfactants cleaning chemicals chemicals detergents polyelectrolytes industrial cleaning degreasers products defoamer
- dispersant biocides l
- A defoamer is used to treat the wastewater to prevent foaming at outfall 001 during some discharge periods..
Normally noncontaminated sumps can become contaminated with radioactivity. When this occurs, the liquid can be pumped to liquid
] rpdioactive waste system for treatment. The decision on the 4
method of treatment depends on the amount of waste needing ,
treatment and the quality of the water being treated. When a sump !
Catawba Nuclear Station NPDES Permit SC0004278 Supplemental Information Revised 7/18/95 Page 8
is diverted to the radwaste equipment, it is considered a part of Radwaste. Chemicals listed as being in the Turbine Building Sump (in Section Outfall 002) will be in Radwaste (outfall 004 when it is routed to this path). Solids or concentrated radioactive by-product generated in the treatment process are disposed of in a State and Nuclear R,egulatory Commission licensed los level
., radioactive waste disposal facility.
3.1.3 Cooling Tower Blowdown - Outfall 005 The Condenser Circulating Water System provides the heat sink for the main condenser and the feedwater pump turbine condensers. This is a closed loop cooling system containing 7.5 million gallons of service water
- per unit.
i After passing through condensers, the warm water is pumped to the l top of the cooling towers. This water is distributed unifonnly across the top to the three cooling towers (per unit) and cascades by gravity to the floor of the cooling tower. Falling water cascades i over fill material which breaks the water into droplets. Fans on the top of the towers pull ambient air in from the sides and past the 4
falling water. From the floor of the cooling tower water flows by gravity back to the condenser.
Because of the concentrating effect of evaporation, a blowdown rate of approximately 5000 gpm is maintained per unit. Bfowdown rates can be higher oflower depending upon system water quality. '
The Low Pressure Service Water system provides makeup to maintain the system volume. :
Chemical treatment of the cooling tower system consists of ;
sulfuric acid, sodium hypochlorite, bromine based oxidant, an organic biocide, and a polyacrylate dispersant. Sulfuric acid is added for pH control of the towers. A polyacrylate dispersant is added for solids deposition control. Sodium hypochlorite and bromine based oxidants are added intermittently for biofouling control.
Normal chemical additions are to the cooling towers of one unit every other day with the other unit's cooling towers blowing down to Outfall 001. It is anticipated that during those times when blowdown is necessary to prevent scaling and control algae growth, when chlorine concentrations exceed discharge specifications, and when the Conventional Waste system cannot Catawba Nuclear station NPDES Permit SC0004278 Supplemental Information Revised 7/l8/95 Page 9
handle the additional volume, it may become necessary to add f either sodium sulfite or sodium nitrite to the cooling' towers in . ,
stoichiometric proportions for dechlorination.
- 1 Additionally, because of restrictions on and of chlorine, an l organic biocide is also added for biofouling control. Currently I approved biocides are Calgon H640, Drew Biosperse 288, Betz Slimicide C79, Buckman Bulab 6002, Calgon H-130, and Drew Biosperse 216. Only one biocide is used at a time. Multiple approvals have been obtained for bidding purposes from different chemical manufacturers.
L The cooling tower blowdown is normally to the Low Pressure Service Water system however, it 'can be aligned to the Conventional Waste system if necessary. Discharges of cooling ' !
tower blowdown are free of detectable amount of treatment L chemicals and is discharged at concentrations ofless than the No l . Observable Effect Concentration for Ceriodaphnia dubia after j mixing with the low pressure service water prior to Lake Wylie.
l-During unit outages, part or all of the Condenser Circulating Cooling system can be drained to outfall 001 and/or the l Conventional Wastewater Treatment System, outfall 002.
3.1.4 Nuclear Service Water !
- The Nuclear Service Water System is a once-through no6-contact L plant cooling water system. This system supplies cooling water to various heat loads in the Auxiliary and Reactor Buildings other ,
, than the secondary (steam) side of the station. It is served by Lake .
Wylie and the Standby Nuclear Service Water Pond - but only one .
l pump stmeture.
l Corrosion inhibitors are used in several system heat exchangers during wet layup conditions. Products used to perform the layup consist of carbohydrazide, nitrites, polysilicates, pclyphosphates, !
j phosphates, molybdates, and borates. These formulations would !
l be used in conjunction with a dispersant and penetrant for deposit control and a biocide for biofouling control. These products would be used so that release concentrations would be below the No Observable Effect Concentration for Ceriodaphnia
,- dubia.
Products used for wet layup and to control clam growth in the safety related nuclear service water system can be discharged to the Catawba Nuclear Station NPDES Permit SC0004278 Supplemental Information Revised 7/18/95 Page 10
\
L l
l l Standby Nuclear Service Water Pond during required system ,
testing (below the NOEC concentration). Also, low concentrations of these products may be discharged to the pond if the discharge path to Lake Wylie automati,cally swaps the discharge to the pond.
l However, product biodegradation and system demand would minimize the discharge concentration. i 3.2 Flows l Discharge 5 Year 5 Year l Average Maximum (mgd) (mgd)

This outfall consists primarily of raw water from Lake Wylie and. is used for plant cooling and receives no treatment prior to discharge! Any chemical additions have been described previously and are monitored in accordance with the NPDES permit requirements.
4.0 Outfall 002 4.1 Description of Discharge Outfall 002 discharges flow from the Conventional Wastewater Treatment l system through a Parshall flume into the Big Allison Creek arm of Lake l Wylie. This system consists of the following:
1 Initial Holdup Pond Concrete 300,000 gallons
! 2 Settling Ponds Clay Lined 5,000,000 gals each
, IFinal Holdup Pond Polymer Lined 1.5 million gallons
(
Normally, inputs are received in the Initial Holdup Pond (IHP) which serves a surge-dampening function to the settling ponds and also allows heavy solids to settle for periodic removal. Solids removed from the IHP l
Catawba Nuclear Station NPDES Permit SC0004278 Supplemental information Revised 7/18/95 Page 11
i- l are dewatered and disposed in a licensed landfill. _ Inputs can bypass the ,
Initial Holdup Pond and be directed to the in-service settling pond if l necessary.
t l From the Initial Holdup Pond flow is directed to the in-service settling I
pond where chemical treatment, mixing, and aeration take place. Shlfuric ll acid and sodium hydroxide are added for pH control. Coagulants can also be added to facilitate the settling of small particles. Additionally, it may be necessary infrequently to oxidize persistent chemicals, with the use of hypochlorite (sodium or calcium) or hydrogen peroxide.
l The settling ponds can discharge directly to Lake Wylie via outfall 002, or be directed to the Final Holdup Pond (FHP) for additional treatment or
! holdup capacity. Treatment in the WC System is on a batch basis. !
L Discharge flowrates can range between 800 gpm and 2000 gpm.
i Recirculanon capability is available for recirculation intra- or inter-basin. :
i The WC System receives inputs directly from the service building sump,
, turbine building sumps, diesel generator catchment sumps, step-up ;
transformer base drainage sumps, sulfuric acid tank containment drainage sump, cooling tower blowdown, secondary containment sumps, and l rainwater from various sources.
L j
! The WC system has an approved groundwater monitoring program which -l l consists of four monitoring wells. Groundwater samples are c'ollected, l l analyzed, and the results reported to SCDHEC in accordance with the ;
!- approved groundwater monitoring plan. l j 4.1.1 Service Building Sump The Service Building Sump receives inputs from the water j treatment room, diesel generator room sumps, and the service building ' floor drains. The sump has an approximate holding volume of 26,500 gallons and two pumps, each with a capacity of i 1350 gpm. Normal alignment is to the Conventional Waste system directly, but can be through the turbine building sump.
The service building floor drains receive miscellaneous leakage and drainage. Chemicalinputs include:

1 4.1.2 Water Treatment Room l i The Water Treatment Room produces filtered water and l demineralized water. All chemicals used, all leakage and I
drainage, and all wastes produced go, directly to the service building sump.
Filtered water is made by taking lake . water, adding a coagulant, filtering up through one of two gravel-to-sand beds and r
chlorinating with chlorine gas to approximately 1.5 mg/l Free Available Chlorine (FAC). When solids are elevated in the lake, alum (aluminum sulfate) may also be used. The beds are flushed on pressure buildup with high velocity lake water.
l Approximately quarterly, or when necessary, each bed is cleaned with approximately 200 gallons of 35% hydrogen peroxide and a surfactant. The peroxide and surfactant is added, the bed is air mixed, allowed to soak, and flushed. The peroxide / surfactant cleaning dissolves mud balls that may have formed. Yearly, approximately 1000 pounds of sand are replaced in each bed as a result of normal losses from backwash carryover.
Demineralized water is made by passing filtered water through a '
carbon bed or a reverse osmosis unit and then through a
, regenerative resin bed. There are two carbon beds, a reverse osmosis unit, and two resin beds. Each carbon bed contains 270 l (t3 and is replenished yearly. Each resin bed contains 510 ft3 and
! is replenished every 3 to 5 years. To regenerate the resin, sulfuric acid and sodium hydroxide are flushed through the bed.

i Each normal regeneration, at the present time, takes approximately l 98 gallons of 93% sulfuric acid and 330 gallons of 50% sodium j hydroxide. Regeneration occurs approximately once a month. The
{
amounts of required acid and caustic will vary as dictated by '
operational requirements. 8
- Approximately quarterly, each resin bed is surfactant cleaned to remove organic film on the resin. '
i 4.1.3 Diesel Generator Roem Sumps 1
The diesel generator room sumps receive inputs from leakage or j draining the diesel generator engine cooling water, fuel oil, and !
lubrication systems. Each of the four sumps has a volume of ~ l approximately 470 gallons and two pumps, each with a capacity of ;
50 gpm.
l The diesel generator engine cooling water systems have a volume l
of 2240 gallons each. The systems are treated with a mixture of i sodium nitrite, borax (sodium tetraborate), sodium bicarbonate and sodium mercaptobenzothiazole (MBT) to maintain a minimum concentration of 2000 mg/l as nitrite. To control bacteria, an approved biocide is added. >
The diesel generator fuel oil and lubrication systems can drain to the sumps, but administrative controls block intentional draining.
For emergency spills, an oil coalescing unit is installed between the sumps and the service building sump. Additionally, the fuel oil contains residual biocide to reduce bacterial breakdown of the oil.
4.1.4 Turbine Building Sumps The turbine building sumps receive inputs from steam generator wet lay-up chemicals, cooling tower drainage (unwatering),
reverse osmosis treatment unit, auxiliary building floor drain sumps, and the turbine building floor drains. Each sump has an approximate capacity of 12,000 gallons and three pumps, each with a capacity of 1350 gpm. Normal alignment is directly to the Conventional Waste system. However, hose connections on the discharge of the pumps allow rerouting to other sumps for unusual circumstances.

50% sodium hydroxide 1,500 gallons biocide 3,800 gallons dispersant 7,600 gallons 93% sulfuric acid 30,000 gallons Curbing provides secondary containment for each of these tanks. l This curbing is sufficient to contain the entire contents of each tank in case of a leak.
4.1.11 Secondary Containment Sumps Secondary containment sumps receive input froin the yard drains. .
Three 10,000 gallon sumps are available for spills or rainfalls less than 10,000 gallons. The sumps can pump to the initial or final ,
holdup pond. By design, greater than 10,000 gallons will put the sump in overflow directly to Lake Wylie.
Other than spills or rainfall, actuation or testing of the chlorinated fire protection system in the yard could overflow a sump. The ,
groundwater drainage system from the plant discharges to the yard r drains. Additionally, the switchyard for the site contains two oil i
trap tanks. Rainfall collected from the switchyard flows through these tanks. These tanks will contain any oil spilled or leaked in ;
i the switchyard.

i This system also receives flow from the oil / water separator and drains l located at the transportation garage located on site. The grease trap !
located at the site cafeteria also flows to this treatment system.
It may be necessary to periodically' remove sludge from the system. The sludge will either be tanked to a municipal sewage treatment system or l dewatered and disposed ofin a State licensed landfill or landfarm.
Small amount of photographic waste (developer and rinse) are disposed of in the WT system. The components of these substances include: i acetic acid potassium sulfite potassium hydroxide l hydroquinone 1-phenyl-3-pyrozolidione glutaraldehyde bisulfite !
glutaraldehyde i
5.4 Treatment Inputs to the sewage treatment system pass through a grit chamber which allow heavy solids to settle out and a bar screen to remove large non-sewage objects and to break large particles. It then passes through a comminutor which cuts and shreds large solids into smaller particles which are more easily digested. From the comminutor, the sewage enters the four cell aeration lagoon where the sewage is decomposed by aerobic bacteria. '
Aeration is provided by blowers / compressors. From the fourth cell, the sewage enters the effluent polishing basin or can be directly discharged to ,
Lake Wylie through outfall 003 if of acceptable quality. The effluent polishing basin is also aerated by blowers which reduces suspended solids, nitrogen, and phosphorous levels. A soda ash solution is added to the effluent of the polishing pond as necessary for pH control.
The effluent flows through a Parshall fiume to record discharge flow.
After this flow passes through a tablet chlorinator, and a chlorine contact chamber, a tablet dechlorinator system, and a dechlorinator contact chamber before being discharge to Lake Wylie. The chlorinator system is not used unless it is necessary in order to meet the fecal coliform limits imposed by the permit.

1 8.1 Fire System )
I Water supply for fire Protection is provided by three full capacity (250 gpm) fire pumps. In addition, two 25 gpm and one 200 gpm jockey pumps (supplied by the Filtered Water System) are provided to prevent frequent 1 starting of the main fire pumps to maintain pressure in the yard mains. If system needs cannot be met with the jockey pumps, the main fire pumps start in sequence as the pressure in the yard mains drop. The system is chlorinated to prevent the survival of Corbicula within the system.
System operability is demonstrated by periodically performing specific tests on the system as described in the March 4, 1986 i correspondence with SCDHEC. '
Testing is performed in such a manner as to minimize the discharge of chlorine to Lake Wylie as described in the Department of Health and Environmental Control letter dated May 2,1986.
8.2 Drinking Water System Flushes Potable water is supplied to the station by York County. A municipal drinking water connection to the site occurred in 1993. Periodically, when new lines are disinfected or repairs are made to existing lines, the lines are flushed as required by the State drinking water regulations. Where possible, these discharges will be routed to a treatment system.
8 . .~. Cooling Tower Drainage After thq initial drainage of the Condenser Circulating Cooling system and i , during system maintenance, a pump is used to dewater any miscellaneous water which leaks into the system. This water, which is raw lake water, is
't Catawba Nuclear Station NPDES Permit SC0004278 Supplemental information Revised 7/18/95 Page 21 l

pumped into the yard drain system which discharges directly to Lake Wylie.
8.4 Miscellaneous System / Component Cleaning
\
8.4.1 Mechanical Cleanings '
' t Heat exchanger and cooling water pipes are periodically mechanically cleaned with bmshes, rods, high pressure water, ,
hydrolaze and other physical means. No chemicals are used during, l
these cleanings, solids are trapped or filtered at the source, and the water flow discharges to the various stations sumps described above.
8.4.2 Chemical Cleanings Systems may need to be cleaned periodically because of scaling or plugging. Other components will be cleaned as necessary for various fouling problems.

10.0 Section 311 Exemption The legislative / regulatory history of the Clean Water Act, Section 311, indicates that an exemption would be allowed where an on-site spill is processed through a
) treatment system capable of eliminating or abating the spill. A Section 311 exemption is therefore requested for the following substances:
15% sodium hypochlorite 10,000 gallons 50% sodium hydroxide 1,500 gallons biocide 3,800 gallons dispersant 7,000 gallons 93% sulfuric acid 30,000 gallons caustic 5000 gallons Curbing sufficient to contain the entire contents of the tank is provided. Drainage from the curbed area is to the WC system via the Service Building Sump.
As discussed, the entire contents of these tanks are contained and are routed to the WC system. The treatment system is capable of containing the spilled material along with normal process waste flows and of mitigating / abating the effects on the receiving water since the system treats the wastes by batch, treatment capacity is 5 million gallons per batch - much greater than any of the tank volumes, and has procedural safeguards to restrict inputs to a discharging basin.

Hydrazine is limited by this permit, however the State Environmental Certification Regulation 61-81 and the Federal Regulations ' Guidelines EstablislIing Test
. Procedures for the Analysis of Pollutants' 40 CFR 136 do not provide a certified test
!. method for this compound. Therefore, the permittee shall monitor this parameter using test procedures which have been submitted to the Department. Other analysis r which may be regulated by permit for which there is no approved regulatory method for analysis will be handled likewise.
t l 5. Recording of Results For each measurement or sample taken pursuant to the requirements of this permit, he permittee shall record the following information:
- a. the exact place, date and time of sampling;
- b. the dates and times the analyses were performed;
- c. the person (s) who performed the analyses and the laboratory certification number where applicable. j
- d. the analytical techniques or methods used; and
- e. the results of all required analyses.
- 6. Additional Monitoring by Permittee If the permittee monitors any pollutant at the location (s) designated herein more frequently than required by this permit, using approved analytical methods as speeded herein, the results of such monitoring shall be included in the calculation and reporting of the values required in the Discharge Monitoring Report Form (EPA-33201). Such increased frequency shall also be indicated. Additional or accelerated monitoring may be require to determine the nature and impact of a non-complying discharge on the environment or to determine if a single non-complying sample is representative of the long term condition (monthly average).
7.. Records Retention l All records and information resulting from the monitoring activities required by this permit including all records of analysis performed and calibration and maintenance of
l Part 1 l Page 9 of 24 Permit No. SC0004278 i
mstrumentation and recordings from continuous monitoring instrumentation shall
! be retained or a minimum of three (3) years, or longer if requested by the Department. The permittee shall furnish to the Department upon request, copies of records required to be kept by this permit. .
- 8. Definitions
- a. The " monthly average", other than for fecal coliform, is the arithmetic .
l mean of all samples collected in a calendar month period. The monthly l average for fecal coliform bacteria is the geometric mean of all samples collected in a calendar month period. The monthly average loading is the l arithmetic average of all individual loading determinations made during the j month.
i b. The " weekly average" is the arithmetic mean of all the samples collected during a one-week period. For self-monitoring purposes, weekly periods in ,
l a calendar month are defined as three consecutive seven day intervals starting with the-first day of the calendar month and a fourth interval containing seven days plus those days beyond the 28th day in a calendar
- month. The value to be reported -is the single highest of the four weekly l averages computed during a calendar month. The weekly average loading is i the arithmetic average of all individual loading determinations made during the week
- c. The " daily maximum" is the highest average value recorded'of samples :
collected on any single day during the calendar month.
i d. The " instantaneous maximum" is the highest value recorded of any sample l collected during the calendar month.
- e. Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual values divided by the number of individual
! values.
- f. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the individual values where N is equal to the number of individual values. The geometric mean is equivalent to the antilo'g of the arithmetic mean of the logarithms of the indiridual values. For purposes of calculating the geometric mean, values of zero.(O) shall be considered to be one (1).

- i. Grab Sample: An individual discrete or single influent or effluent portion of l -
at least 100 milliliters collected at a time representative of the discharge and over a period not exceeding 15 minutes and retained separately for analysis.
Instantaneous flow measured at the time of grab sample collection shall be i used to calculate quantity.
- j. Composite Sample: One of the following four types of composite samples as defined is specified within this permit:
t (1) An influent or effluent ponion collected continuously over a specified ,
l period of time at a rate proportional to the flow.
(2) A combination of not less than 8 influent or effluent grab samples
- collected at regular (equal) intervals over a specified period of time, i
! properly preserved, (See part I.C.4.) and composited by increasing the !
volume of each aliquot in proportion to flow. If continuous flow !
measurement is not used to composite in proportion to flow, the ,
following method will be used: Take an instantaneous flow :
measurement each time a grab sample is collected. At the end of the sampling period, sum the instantaneous flow measurements 'to obtain a
! total flow to determine the partial amount (percentage) of each grab j sample to be combined to obtain the composite sample.
(3) A combination of not less than 8 influent or effluent grab samples of L
equal volume but at variable time intervals that are inversely proportional to the volume of the flow. That is, the time interval between al aliquots is reduced as the volume of flow increases.
(4) A combination of not less than 8 influent or effluent grab samples of l constant (equal) volume collected at regular (equal) time intervals over a specified period of time, while being properly preserved.

- a. The " monthly average", other than for fecal coliform, is the arith-metic mean of all samples collected in a calendar month period. The ;
monthly average for fecal coliform bacteria is the geometric mean of all samples collected in a. calendar month period. The monthly !
average loading is the arithmetic average of all individual loading determinations made during the month, 4
- b. The " weekly average" is' the arithmetic mean of all the samples collected during a one-week pe riod. For self-monitoring pur-poses, weekly periods in a calendar month are defined as three
!~
consecutive, seven day intervals starting with the first day of the calendar month and a fourth interval containing seven days 3
plus those . days beyond the 28th day in a calendar month. The l
. value to be reported is the. single highest of the four weekly

- c. The " daily maximum" is the highest average value recorded of samples collected on any single day during the calendar month,
- d. The " instantaneous maximum" is the highest value recorded of any sample collected during the calendar month,
- e. Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual values divided by the number of indi-vidual values.
- f. Geometric Mean: The geometric mean of any set of value's is the Nth root of the product of the individual values where N is equal to the number of individual values. The geometric mean is equivalent to l
the antilog of the arithmetic mean of the logarithms of the indi-vidual values. For purposes of calculating the geometric mean, values of zero (0) shall be considered to be one (1).

- 1. Grab Sample: An individual discrete or single influent or effluent portion of at least 100 milliliters collected at a time representa-tive of the discharge and over a period not er.ceeding 15 minutes and retained separately for analysis. Instantaneous flow measured at the time of grab sample collection shall be used to calculate quan-
, tity.
i
- j. Composite Sample: One of the following four types of composite samples as defined is specified within this permit:
- (1) An influent or effluent portion collected continuously over a specified period of time at a rate proportional to the flow.
(2) A combination of not less than 8 influent or effluent grab samples collected at regular (equal) intervals over a specified period of time, properly preserved, (See part I.C.4.) and composited by increasing the volume of each aliquot in propor-tion to flow. If continuous flow measurement is not used to composite in proportion to flow, the following method will be used: Take an instantaneous flow measurement each time a grab sample is collected. At the end of the sampling period, sum the instantaneous flow measurements to obtain a total flow to determine th'e partial amount (percentage) of each grab sample to be combined to obtain the composite sample.
PART I Page 18 of 31 Permit No.SC0004278 1
(3) A combination of not less than 8 influent or effluent grab samples of equal volume,'but at variable time intervals that are inversely proportional to the volume of the flow.. That is, the time interval between aliquots is reduced as the volume of flow s increases.
(4) A combination of not less than 8 influent or effluent grab samples time of constant (equal) volt.me collected at regular (equal) properlyintervals preserved.over a specified period of time, while being Continuous flow or the sum of iristantaneous flows measured and averaged for the specified compositing time period shall be used with composite sample results to calculate quantity.

l Catawba Nuclear Station requests approval to begin using Dimethylamine (DMA) which will '
be discharged in non-toxic concentrations. This product will be used in the plants feedwater systems in order to reduce and prevent corrosion fouling.
Dimethylamine has an NOEC concentration of 20 ppm for ceriodaphnia 'dubia. The proprietary product to be used (Pre- Tect 9_002) has a NOEC concentration of 1000 ppm. The
- product will be used in the system at conce7ttration less than the NOEC and vill be combined with other flows prior to discharging to Lake Wylie via outfall 002. Attached please find a ,
Chronic Toxicity Study performed on Pre - Tect 9002 as well as' an MSDS sheet for the product.
The SCDHEC Industrial Wastewater Division has approved the use of this product for
. Oconee Nuclear Station (See attached approval letter dated June 28,1995). We are requesting !'
a similar approval letter be issued for Catawba Nuclear Station. However, we are requesting that the approval letter reference dimethylamine (DMA) rather than the proprietary. j manufactures name in order to have flexibility in selecting different product suppliers without -
seeking additional approval.
