Outfall 001 Circulating Water System

Discharge Information for Outfall 001 (Circulating Water System)

EPA Form 2C Section IL, Flows, Sources of Pollution and Treatment Technologies PartB, Description of. (1) All operationscontributingwastewater to the effluent, includingprocess wastewater, sanitarywastewater, cooling water,and storm water runoff; (2) The averageflow contributedby each operation; and (3) The treatment received by the wastewater.

Section V, Intake andEffluent Characteristics Part V.D, List of Pollutantsfrom Form 2C, Tables 2C-3 and 2C-4 Discharge includes wastewater from the following sources:

All permitted outfalls from this facility ultimately combine with the Circulating Water System and are discharged to the Atlantic Ocean. These oufalls are sampled at representative sample points prior to introduction to the Circulating Water System to ensure compliance with NPDES Permit effluent limitations and monitoring requirements.

In addition to the identified permitted outfalls which discharge to the Circulating Water System, the sources below may also be introduced:

" Cooling water drawn from three intake velocity caps and discharged through eleven double discharge diffuser nozzles in the Atlantic Ocean

• Closed loop cooling system leakage into the Service Water System.

• Residual chlorine. Chlorine is injected into the Circulating and/or Service Water Systems to prevent biofouling.

" Neutralization Tank discharge of Condensate Polishing System and Makeup Water Treatment System wastewater

" Makeup Water Treatment System waste mineral concentrates

• System drainage from systems which are not directed to another outfall

" Various seawater containing sumps that collect seawater leakage and return it to the Circulating Water System.

• Condensate hotwell discharges performed to control chemistry parameters, lower hotwell level, or drain for system maintenance.

• Rinses of the Condensate Polishing System in support of start-up and periodically during standby conditions, rinses of the resin vessels following regenerations, regeneration wastewater, sampling system and grab sample waste, system leakage, and system drainage for maintenance (see description below).

" Steam Generator drainage

" Circulating Water System and Service Water System Forebay Water. Periodically sediment is removed from the forebays by a pumping process. The sediment is typically collected in lined dumpsters and the ocean water is returned to the forebay or may be directed to the Storm Drain System which ultimately discharges to Outfall 001.

Dischar2e description:

The Circulating Water System provides Atlantic Ocean cooling water to the main condensers where the steam exhausted from the low pressure sections of the turbine is condensed and subsequently returned to the Condensate System and Feedwater System. The Circulating Water System also supplies cooling to several mechanical vacuum pump heat exchangers in the Condenser Vacuum System. The Service Water System provides Atlantic Ocean cooling water to various subsystem heat exchangers which are required to support normal operating conditions, shutdown conditions and emergency conditions.

The cooling water flow in the Circulating Water System and Service Water System is conveyed by large high capacity centrifugal pumps. During normal full power operation three Circulating Water System pumps are in operation each with a rated pumping capacity of approximately 130,000 gpm and two Service Water System pumps Outfall 001, p. 1

are in operation each with a rated pumping capacity of approximately 10,500 gpm. The actual operational capacities of these pumps has exceeded their documented rated capacities. The increased pumping capacity is attributable to conservative estimates of operational pumping capacities by the pump vendor and the operation of a single nuclear unit versus two unit operation. Operation of a single nuclear unit results in a reduction in the Circulating Water System flow resistance. During most periods of the year when ocean temperatures are cold, a portion of the ocean cooling water leaving the condenser is recirculated through the condenser to maximize plant efficiency by optimizing the temperature and pressure of the secondary coolant water exiting the condenser water boxes. During these periods when ocean cooling water is being recirculated through the condenser, total cooling water flow is reduced and the temperature rise across the condenser is elevated. The effect of condenser cooling water recirculation can be seen in monthly Discharge Monitoring Reports which document cooling water flow and temperature increase across the condensers. During plant shutdown conditions (e.g. plant refueling outages) there is no transfer of heat to the Main Condenser. During refueling, the Steam Generators are placed in a wet layup condition and the Condensate System and Feedwater System are not in operation. During refueling, the Service Water System pumps are operated to remove heat from the Spent Fuel Cooling System and to provide cooling to other plant heat loads. A Circulating Water System pump (or pumps) may be operated during a refueling outage to support effluent discharges.

The Circulating Water System consists of the following principal structures:

" Two tunnels connecting the plant site with three submerged offshore intakes and a multiport discharge diffuser

• An intake transition structure

• A pumphouse for the Circulating Water System and a pumphouse for the Service Water System

" Flumes which join the intake transition structure to the pumphouses

" A discharge transition structure

• An underground piping system, interconnecting the pumps in the pumphouses, the Main Condensers, heat exchangers and the transition structures Current overview diagrams of the Circulating Water System and Service Water System follow this description.

During normal operation, the Circulating Water System provides a continuous flow of approximately 390,000 gpm to the condensers and the Service Water System provides a continuous flow of approximately 21,000 gpm to various subsystem heat exchangers.

The Circulating Water System tunnels start 260 feet below the plant level (240 feet below mean sea level), at the bottom of vertical 19'-0" finished diameter land shafts, and extend out under the ocean at an ascending grade of about 0.5 percent until they reach their respective offshore terminus locations about 160 feet below the ocean's surface. The tunnels, which were machine bored through bedrock to a 22'-0" diameter, are concrete lined to provide the finished 19 foot finished diameter.

The intake tunnel is approximately 17,000 feet long, and is connected to the ocean by means of three 9'-10 1/2" finished diameter concrete-lined shafts, spaced between 103 and 110 feet apart and located approximately 7000 feet off the shoreline in 60 feet of water. A submerged 30'-6" diameter concrete intake structure intake head is mounted on the top of each shaft to minimize fish entrapment by reducing the intake velocity.

The discharge tunnel is approximately 16,500 feet long, and is connected to the ocean by means of eleven, 5'-l" finished inside diameter concrete lined shafts, spaced about 100 feet apart, located approximately 5000 feet off the Seabrook Beach shoreline in water up to 70 feet deep. A double-nozzle diffuser is attached to the top of each shaft to increase the discharge velocity and diffuse the heated water.

The circulating water portion of the pumphouse encloses three 14' wide circulating water travelling screens and three circulating water pumps. A reinforced concrete wall separates the circulating water portion from the service water portion of the pumphouse. The Service Water System pumps are located in the service water portion of the pumphouse as are the service water travelling screens. The circulating water is pumped through a 11 foot diameter pipe to the condensers and is returned through a 10 foot diameter discharge pipe connected with the tunnel transistion structures. Water to the service water section of the pumphouse is supplied by two pipes branching off each of the tunnel transition structures.

Outfall 001, p. 2

This outfall receives inputs from all of the other outfalls described within this permit renewal application. All other sources listed in those outfalls ultimately are discharged via this system.

Outfall 001 also receives the effluent from the Water Treatment System. This effluent includes a waste mineral concentrate stream and the effluent from the Neutralization Tank.

Trace quantities of typical janitorial cleaning products may also be incidentally introduced into floor drains and into the Circulating Water System in conjunction with cleaning activities. The practice is to dispose ofjanitorial cleaning wastes which have been used outside of the Radiologically Controlled Area in the sanitary waste system which is discharged to the Town of Seabrook Publically Owned Treatment Works. Janitorial cleaning wastes which have been used inside of the Radiologically Controlled Area have the potential to contain radioactive contamination and therefore must be disposed of in floor drains or sinks which are directed to the Waste Test Tanks (Outfall 025D) and ultimately discharged to Outfall 001. Wastewater collected in the Waste Test Tanks is sampled for radioactivity content prior to each discharge to ensure Nuclear Regulatory Commission radioactive effluent limits are complied with prior to discharge. Compliance with Nuclear Regulatory Commission radioactive effluent limits specified in 10 CFR 20 is a requirement of the Seabrook Station Operating License.

• The NPDES Permit prohibits Circulating Water System chlorination during the thermal backflush evolution.

Chlorination of the safety-related Service Water System during the backflush evolution is authorized.

" Additional discharge wastewater description to be provided in update to "Alternatives to Thermal Backflushing" study if thermal backflush is proposed to be used.

Discharge description:

The NPDES Permit requires that if thermal backflushing is proposed to be used, the December 16, 1994, "Alternatives to Thermal Backflushing" study will be updated and submitted to the Regional Administrator, the Director of the NH Department of Environmental Services and the Technical Advisory Committee prior to conducting this evolution.

A general description of thermal backflushing follows. Comprehensive discharge description to be provided in update to "Alternatives to Thermal Backflushing" study if thermal backflush is proposed to be used.

In addition to chlorination, thermal backflushing of the intake tunnel may be employed to remove sessile biofouling organisms attached to system components. This method involves the reversal of the normal cooling water flow such that the three intake structures serve as the discharge points (Outfall 003) and the discharge diffuser ports, conversely, function as the intake structure.

Temperatures within the intake tunnel will be elevated to a maximum of 120 OF for a maximum of 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. The entire flow reversal and heat treatment cycle will occur over a six-hour period at a cooling water flow rate not exceeding 500,000 gallons per minute. There will be no chlorination of the condenser cooling water during the thermal backflushing treatment. The thermal backflushing operation may be used infrequently to compliment the normal Circulating Water System chlorination procedures for those sessile organisms that are not controlled by the sodium hypochlorite injection or for those organisms located upstream of the sodium hypochlorite injection points.

Condensate Polisher Building Discharge description:

The Floor Drainage Oil/Water Separation System is designed to process non-corrosive oily and potentially oily drainage and leakage sources to produce an effluent containing less than 15 mg/L oil content which conforms to the Effluent Guidelines and Standards set forth by the EPA in 40 CFR 423 for the Steam Electric Power Generating Point Source Category. The processed effluent is discharged directly to the Circulating Water (CW) discharge (Outfall 001).

The Oil/Water Separation System is comprised of an oil separator, which contains a gravity settling section to which the oil/water streams are piped, and a tilted plate separator section to effect separation of oil from water. An effluent tank with a pump and a coalescing filter are also provided. The filter is utilized for final polishing of the effluent prior to discharge. Operation of the Oil/Water Separation System is initiated upon reaching a setpoint level in the effluent tank.

Each separator is designed to process water with an oil content less than 1500 mg/L and discharge a maximum of 85 gpm (122,400 gpd). The gravity settling section is provided to limit suspended solid loading into the oil separation section to 20 ppm. The down flow tilted plate separator is designed to process an oil/water solution and produce an effluent with an oil concentration conforming to EPA effluent guidelines. The final polishing coalescing filter is included in the event that separator loadings exceed design values. This filter can reduce the oil content from about 15 mg/L to less than 10 mg/L. Separated oil is collected in the oil holding tank and is removed periodically. Settled solids in the gravity separator are likewise removed.

Oil/Water Separator Vault #1 is located in the yard area below grade adjacent to the east side of the Turbine Building. The location of the oil/water separator is sufficiently deep to prevent the freezing of the water at low or no-flow conditions. The vault housing the oil/water separator, sump and filter is covered to protect the system from the environment. The vault is ventilated by a ventilation fan. Electrical equipment and lighting in the vault area are explosion proof.

Bottoms fluid from the Blowdown Flash Tank is discharged directly to the Circulating Water System (Outfall 001) when the Steam Generator Blowdown Recovery sub system is unavailable (e.g. during regeneration and rinsing of the demineralizer beds), during plant start up and shut down, and when the quality of the effluent is unacceptable for reuse in the Condensate System.

Discharge description:

Outfall #025 is a combination of four discrete waste streams which are individually sampled to ensure compliance with NPDES Permit effluent limitations and monitoring requirements. The four outfall designations are as follows:

025A -Steam Generator Blowdown 025B -Steam Generator Blowdown Dernineralizer Rinses 025C -Waste Holdup Sump 025D -Waste Test Tanks and Recovery Test Tanks The following description is for 025A Steam Generator Blowdown only. Because portions of the other 025 outfalls interface with 025A, they are also briefly discussed. The Steam Generator Blowdown System removes suspended solids and dissolved impurities from the secondary side of the Steam Generators. Removal of these solids and impurities minimizes chemical deposition on the Steam Generator tube surfaces. This is important for limiting any reduction in the heat transfer capability (primary to secondary) of the plant and for reducing the rate of Steam Generator tube corrosion. A current overview drawing of the Steam Generator Blowdown System follows this description.

The Steam Generator Blowdown System also aids in limiting the buildup of radioactive isotopes in the Steam Generators if a primary to secondary leak occurs.

During refueling or extended outages, a portion of the Steam Generator Blowdown System is used in conjunction with the Steam Generator Recirculation and Wet Layup System to maintain the required chemistry control regime in the Steam Generators.

The major sub-systems in the Steam Generator Blowdown System are:

Steam Generator Blowdown System Flash Tank Subsystem:

This sub-system receives the effluent from the (four) Steam Generators. The blowdown fluid pressure is reduced from 1000 psig to 55 psig. Approximately 30% of the blowdown liquid is flashed to vapor in the Blowdown Flash Tank at this pressure. The distillate is then normally directed to the feedwater heater shell side for reuse in the Feedwater System. The remaining liquid (bottoms) is then cooled in the Blowdown Flash Tank bottoms coolers and normally directed to the Steam Generator Blowdown Recovery sub-system and then to the main condenser for reuse in the Condensate System.

Outfall 025A, p. 1

When the Blowdown Flash Tank distillate's normal flowpath to the feedwater heater shell side is unavailable, the vapor can either be released to the atmosphere, if it is of acceptable quality, or directed to the flash steam condenser/cooler. This condensate is then transferred to either the Waste Test Tanks (Outfall 025D) for discharge or to the main condenser for reuse in the Condensate System.

When the Steam Generator Blowdown Flash Tank bottoms recovery flowpath through the blowdown recovery subsystem is unavailable, the liquid can be discharged via the Circulating Water System (Outfall 001), if the quality is acceptable, or if unacceptable it will be directed to either the Blowdown Evaporation sub-system or to the Floor Drain Tanks.

Steam Generator Blowdown System Recovery Subsystem:

This sub-system receives the cooled fluid from the Blowdown Flash Tank bottoms coolers. The liquid is further cooled (maximum temperature 11 0°F) prior to being processed through the blowdown demineralizer skid. The demineralizer skid removes suspended solids and contaminants from the blowdown liquid. After the fluid leaves the demineralizer it is (normally) returned to the main condenser for reuse in the Condensate Systerm. Otherwise it is directed to the Waste Holdup Sump (Outfall 025C) for discharge if the main condenser is unavailable.

Steam Generator Blowdown System Evaporation Subsystem:

This sub-system may be used when there is a primary to secondary leak in the Steam Generator tubes. The evaporators separate the potentially reusable distillate and simultaneously concentrate any contaminants in the evaporator bottoms liquid. The distillate is directed to the distillate cooler, where non-condensable gases are transferred to the equipment vent system for disposal. The condensate is accumulated and, if the conductivity is acceptable, will be sent to the main condenser. Otherwise it will be sent to the Waste Test Tanks or recirculated back to the evaporator for further processing. The bottoms product is concentrated in the bottom of the evaporator by recirculating it back to the evaporator inlet after it has been through the bottoms cooler. The concentrated liquid is periodically discharged to the Waste Concentrate Tank for further processing. If the evaporators are out of service, a valve line up can be manually performed to transfer the blowdown liquid to the Liquid Waste System. The Liquid Waste System evaporator would then process the Steam Generator blowdown liquid for transfer to the Waste Test Tanks (Outfall 025D) for discharge.

Steam Generator Blowdown System Startup The Steam Generator Blowdown subsystems are lined up for operation concurrently with the reactor plant startup.

After the Steam Generator pressures have increased, flow to the Blowdown Flash Tank is commenced. During startup, all the system controls and valve manipulations are done manually. Initial blowdown rates are set at maximum to establish, as rapidly as possible, the Steam Generator secondary water chemistry requirements. This blowdown flow is normally aligned directly to the Circulating Water System (Outfall 001) during plant start up.

Once steady state conditions are established, controls are placed in automatic operation. Typically, during plant startup, the Blowdown Flash Tank vapor is aligned to the secondary system for reuse. Steam Generator blowdown liquid bottoms typically stay aligned to the Circulating Water System until the plant is at full power. The recovery system is normally placed in service after reaching full power.

The Blowdown Flash Tank subsystem operates automatically after startup is completed. The startup of the Steam Generator Blowdown Recovery Subsystem is manually accomplished. Prior to placing a demineralizer in service it is subjected to a pre-service rinse. The pre-service rinse water is directed to the Turbine Building sump which is processed by Oil/Water Separator Vault #1 (Outfall 022) and ultimately discharged to the Circulating Water System (Outfall 001). The Steam Generator blowdown liquid flow is then admitted to the demineralizers in the Steam Generator Blowdown Recovery Subsystem, and the effluent is normally returned to the Main Condenser for reuse in the Condensate System. The Steam Generator Blowdown Evaporation Subsystem may be manually started if radioactivity has been detected in the Blowdown Flash Tank Subsystem and further liquid processing is desired.

Outfall 025A, p. 2

Normal Operation The Steam Generator Blowdown subsystems processes are automatically controlled after the manual startup requirements have been fulfilled. Although subsystem processes are continuously monitored for radiation and conductivity levels, periodic sampling for chemical analysis is also required. A small quantity of the blowdown from each steam generator is drawn off automatically into the sample system for monitoring of the radioactivity and chemical parameters in the blowdown. This action ensures the quality of the Steam Generator blowdown effluent will support its reuse; unsatisfactory quality will necessitate storage and subsequent discharge. Normal system operation requires minimal operator attention. The operator monitors local parameters and corrects any undesirable conditions as they develop.

Steam Generator Blowdown System Shutdown Typically the Steam Generator Blowdown System is removed from service only for maintenance or during a plant outage in which the the reactor is shut down and the primary system temperature is reduced to 350 OF or below. The bottoms of the Blowdown Flash Tank are normally directed to the Circulating Water System (Outfall 001) when the plant power level has been decreased to approximately 30%. The Steam Generator Blowdown System is normally shutdown when steam pressure in the Steam Generators decreases to below 50 psig. The system is shutdown by isolating all flow paths into and out of all subsystems.

The Steam Generator Blowdown Flash Tank Subsystem is filled with water, vented, and isolated if shutdown is for an extended duration. The Steam Generator Blowdown Recovery Subsystem is shutdown by isolating the subsystem and aligning the controls to shutdown.

The Steam Generator Blowdown Evaporation Subsystem is isolated and shutdown after the components and the discharge piping have been flushed with evaporator distillate. Demineralized water is used to flush the subsystem, evaporator demister pad, and to fill components to capacity. The subsystem is vented to ensure that filling of system components is completed. The subsystem controls are aligned for shutdown, any residual heat from the components will be dissipated to the building environment.

During a prolonged shutdown period such as a refueling outage, a portion of the Steam Generator Blowdown System piping is utilized for Steam Generator wet lay-up and recirculation. When the system is aligned to recirculate a Steam Generator, the blowdown flow path is used, but is isolated from the Blowdown Flash Tank. This flow path functions as the supply path to the Steam Generator Wet Layup System. The return path from the Steam Generator Wet Layup System to the Steam Generator is through the Emergency Feedwater/Feedwater Systems. This alternate flow path can also be used during a refueling or maintenance outage to drain a Steam Generator. Steam Generator drainage can directed to the Turbine Building sump for processing by Oil/Water Separator Vault #1 (Outfall 022),

the Storm Drain System, the Waste Holdup Sump (Outfall 025C) or the Waste Liquid processing system (Outfall 025D) prior to discharge to the Circulating Water System (Outfall 001).

Demineralizer Regeneration Support equipment is needed to regenerate the resin beds in the demineralizers. The regeneration equipment consists of an Acid Skid, a Caustic Skid and the Waste Holdup Sump (Outfall 025C). The Acid Skid is used to reactivate the Cation (positive ion) resin beads within the mixed-bed demineralizers and the lead cation demineralizer. The Caustic Skid reactivates the Anion (negative ion) resin beads within the mixed-bed demineralizers. The regeneration waste water is directed to the Waste Holdup Sump. The Waste Holdup Sump liquid is discharged to the Waste Liquid System which is discharged to the Circulating Water System (Outfall 001). Manual startup of this process is needed to initiate the regeneration cycle. After the process is started the remainder is normally automatically sequenced. The entire regeneration process can be manually controlled. Interlocks ensure that only one mixed-bed demineralizer is regenerated at a time. Interlocks will also stop the regeneration cycle if there is not enough Acid or Caustic available to complete a cycle or if the level in the Waste Holdup Sump is above a setpoint level.

Upon completion of the regeneration the demineralizer resin beds are rinsed with Steam Generator blowdown water or demineralized water. The rinse water is sampled to ensure compliance with the NPDES Permit effluent Outfall 025A, p. 3

limitations and monitoring requirements for Outfall 025B. The rinse water is ultimately directed to Outfall 001.

Before the demineralizer beds are placed in service, a pre-service rinse of the beds is performed with the waste water being directed to the Turbine Building Sump. The pre-service rinse water is processed by OillWater Separator Vault

1. 1 (Outfall 022). Upon completion of the pre-service rinse the demineralizer is placed in service with its discharge directed to the main condenser for reuse in the Condensate System.

The current NPDES Permit maximum daily flow limit for Outfall 025 is 425,000 GPD.

The maximum capacity for the Steam Generator Blowdown flow rate is approximately 100 gpm from each of the four Steam Generators. This flowrate represents total flow from each Steam Generator. The Blowdown Flash Tank liquid bottoms are discharged at a rate of approximately 70 gpm to the Circulating Water System (Outfall 001). The Blowdown Flash Tank distillate is returned to the secondary system at a rate of approximately 30 gpm-. These maximum flowrates would normally be used only during plant startups, shutdowns or chemical upsets.

The actual average flow from Outfall 025A for the period 2000 - 2004 is 81,075 GPD.

Discharge frequency:

Outfall 025A is a continuous discharge which is initiated on an intermittent basis. The Steam Generator Blowdown discharge is performed when the Steam Generator Blowdown System Recovery Subsystem is unavailable, also during plant startup and shutdown evolutions and when the quality of the Steam Generator Blowdown Flash Tank bottoms liquid is unacceptable for reuse in the Condensate System. The discharge duration may range from a very short duration to a week or more on a continuous basis.

The rinse water source may either be Steam Generator Blowdown water or demineralized water.

Discharge description:

Outfall #025 is a combination of four discrete waste streams which are individually sampled to ensure compliance with NPDES Permit effluent limitations and monitoring requirements. The four outfall designations are as follows:

025A -Steam Generator Blowdown 025B -Steam Generator Blowdown Demineralizer Rinses 025C -Waste Holdup Sump 025D -Waste Test Tanks and Recovery Test Tanks The following description is for 025B Steam Generator Blowdown Demineralizer Rinses only. Because portions of the other 025 outfalls interface with 025B, they are also briefly discussed.

This discharge consists of rinse water used to remove impurities from the demineralizers prior to their use for Steam Generator blowdown recovery. The demineralizer impurities result from the regeneration of the resins with sulfuric acid and sodium hydroxide. The acid is used to reactivate the cation (positive ion) resin beads within the mixed-bed and cation bed demineralizers. The caustic reactivates the anion (negative ion) resin beads in the mixed-bed demineralizers. Manual startup of this process is required to initiate the regeneration cycle. After the process is started, the remainder is normally automatically sequenced. The entire regeneration process can be manually controlled.

Upon completion of the regeneration the demineralizer resin beds are rinsed with Steam Generator Blowdown Flash Tank bottoms liquid water or demineralized water. The rinse water is sampled to ensure compliance with the NPDES Permit effluent limitations and monitoring requirements. The rinse water is normally directed to Outfall 001. Before the demineralizer beds are placed in service, a pre-service rinse of the beds is performed with the waste water being directed to the Turbine Building Sump. The pre-service rinse water is processed by Oil/Water Separator Vault #1 (Outfall 022). Upon completion of the pre-service rinse the demineralizer is placed in service with its discharge directed to the main condenser for reuse in the Condensate System.

Outfall 025C, p. 1

Support equipment is needed to regenerate the resins in the Steam Generator Blowdown System recovery subsystem demineralizers. The basic regeneration equipment consists of an Acid Skid, a Caustic Skid and the Waste Holdup Sump.

Sulfuric acid is used to reactivate the Cation (positive ion) resin beads within the mixed-bed demineralizers and the lead cation bed demineralizer. Sodium hydroxide is used to reactivate the Anion (negative ion) resin beads within the mixed-bed demineralizers. Following a cation bed regeneration, the contents of the sump may be acidic with pH less than 2. The Waste Holdup Sump transfers liquids to the Waste Liquid System for direct discharge to the Circulating Water System (Outfall 001) or to either of the Chemical Drain Treatment Tanks which are directed to the Waste Test Tanks (Outfall 025D). Manual startup of this process is needed to initiate the regeneration cycle. After the process is started the remainder is automatically sequenced. The entire regeneration process can be manually controlled. Interlocks ensure that only one mixed-bed demineralizer is regenerated at a time. Interlocks will also stop the regeneration cycle if there is not enough acid or caustic available to complete a cycle, or if the level in the Waste Holdup Sump is above a setpoint level.

The Steam Generator Waste Holdup Sump is a 30,000 gallon sump designed to contain fluids from the regeneration of the demineralizer beds. It is a concrete sump lined with PlasiteTM liner. The sump also captures some of the floor drains from the demineralizer room. The sump is normally directed to the Waste Liquid System for direct discharge to the Circulating Water System. It is sampled once prior to or during batch discharge for oil and grease and total suspended solids. The relatively low flow volume of the discharge and the buffering action of the seawater ensures that all pH limits at Outfall 001 are met. The sump may also be discharged to the Chemical Drain Treatment Tanks which are directed to the Waste Test Tanks. There is a recirculation system on the sump which allows for mixing and sampling prior to discharge. This recirculation system also contains components which remove larger suspended solids. The maximum discharge rate for the Waste Holdup Sump is 75 gpm.

Discharge description:

Outfall #025 is a combination of four discrete waste streams which are individually sampled to ensure compliance with NPDES Permit effluent limitations and monitoring requirements. The four outfall designations are as follows:

025A -Steam Generator Blowdown 025B -Steam Generator Blowdown Demineralizer Rinses 025C -Waste Holdup Sump 025D -Waste Test Tanks and Recovery Test Tanks The following description is for 025D Waste Test Tanks and Recovery Test Tanks only. Because portions of the other 025 outfalls interface with 025D, they are also briefly discussed.

The Waste Test Tanks (Outfall 025D) receive inputs from many sources. Floor drains that are located within the Radiologically Controlled Area are directed to the Waste Test Tanks (with a few exceptions).

Most of the inputs to the tanks are normally processed through a vendor treatment system normally consisting of filtration and demineralization. Reverse Osmosis capability is also provided and operated intermittently when necessary. Other plant equipment for waste solidification and liquid waste treatment is not currently being used and there are no plans for use in the future. The Waste Test Tanks are discharged Outfall 025D, p. 1

through the Waste Liquid System to the Circulating Water System (Outfall 001). The tanks have recirculation capability and are limited to a discharge rate of 150 gpm by pump design capacity.

The Recovery Test Tanks may receive inputs from the same sources as the Waste Test Tanks as well as the Steam Generator Blowdown System Recovery Subsystem evaporators and Waste Liquid System evaporators. These tanks may also be discharged through the Waste Liquid System to Outfall 001. The Recovery Test Tanks also have recirculation capability and a maximum discharge rate of 150 gpm by pump design capacity.

Section V, Intake andEffluent Characteristics Part VD, List ofPollutantsfrom Form 2C, Tables 2C-3 and 2C-4 Discharge includes wastewater from the followin2 sources:

Cooling Tower discharges include the following evolutions. Each of the following discharges are sampled to ensure compliance with the effluent limitations and monitoring requirements of the NPDES Permit.

" Cooling Tower blowdown - primarily potable water with some seawater present. Chemicals introduced include sodium hypochlorite for biological fouling control and sodium silicate as a scale inhibitor. Blowdown may be performed to reduce the salinity and/or total dissolved solids in the Cooling Tower to maintain heat transfer capabilities.

" Cooling Tower discharges - other discharges of Cooling Tower water occur when Service Water System cooling is swapped from the ocean water supply to the Cooling Tower, and upon return to the ocean water supply.

Discharge description:

The Cooling Tower (part of the Service Water System) is designed to provide cooling water to plant systems.

During normal operating conditions, extended use of the Cooling Tower is infrequent. Normally, the cooling water for plant systems is supplied by the ocean Service Water pumps, however on occasion the Cooling Tower is placed in service providing the cooling water supply. The Seabrook Station Operating License requires the Cooling Tower be placed in service on a quarterly basis to verify that the cooling water supply can be aligned to the safety-related source of cooling water provided by the Cooling Tower. This evolution occurs approximately every six weeks because each of the two Cooling Tower water trains must be tested each quarter. The Cooling Tower may also be operated to allow maintenance to be performed on the ocean cooling water pumps or during winter months to warm the fresh water supply in the tower basin. The Cooling Tower provides a safety-related source of cooling water in that it is designed to function after a seismic event where it is postulated that the ocean cooling water supply is unavailable due to collapse and blockage of the cooling water tunnels. During accident conditions involving the unavailability of the ocean cooling water supply, the Cooling Tower would supply cooling water to plant systems that are required for safe shutdown. The entire Cooling Tower is constructed over a storage basin that contains 3,900,000 gallons of fresh water (primarily). This volume of water is sufficient to dissipate the design heat loads for seven days without the addition of makeup to the basin The Cooling Tower is comprised of a storage basin, two centrifugal pumps, three fans, a spray header and associated piping and components. The system pumps provide flow through the plant heat exchangers to remove heat. Heated water is returned to the Cooling Tower and is discharged through a spray header. The spray headers form a horizontal grid and are situated directly above the ceramic fill in the Cooling Tower. The ceramic fill is composed of brick-like clay tiles built up in layers supported by cast iron lintels. Each tile has vertically oriented, square holes which, when the tiles are layered, form thousands of offset, cascade water paths through the fill. The cascade water paths provide even distribution and increased fill surface area, which enhances the cooling process. As the heated water passes downward through the fill, an induced flow of cooling air passes upward through the fill. The heat in the service water is transferred to the air flowing in the opposite direction. The cooled service water falls into the storage basin and is ready to repeat the cycle. The heated air is expelled via the Cooling Tower fan velocity stacks on top of the structure. Some water droplets are entrained into this air flow, but are significantly removed by a series of mist eliminators. The mist eliminators limit carryover to 0.03%.

Outfall 027, p. 1

Normal makeup water is supplied from the Potable Water System. Water may also be supplied from other sources if potable water is not available or a more rapid makeup is desired. Some other sources include: seawater from the forebays, fire protection main water, water from the Brown's river, seawater from Hampton Harbor, or any other onsite water that may be available for use in an emergency.

Although the Cooling Tower can operate on seawater, it is prudent to maintain the salinity and total dissolved solids of the basin water as low as possible during normal operation. The normal total dissolved solids level of the Cooling Tower water is 3000 - 5000 ppm (compared to seawater at 35,000 ppm). This is accomplished by aligning the Cooling Tower water discharge path to Outfall 001 for a period of time when first placing the system in operation.

This action flushes seawater from the system piping before returning the discharge to the Cooling Tower. When the Cooling Tower is removed from service, the Cooling Tower water that is trapped in the Service Water System piping is displaced by seawater and discharged to Outfall 001. The evolution of placing the tower in service, and removing it from service, typically results in a discharge of between 50,000 to 200,000 gallons of Cooling Tower water.

Cooling Tower blowdown is a discharge of a volume of the Cooling Tower water inventory to Outfall 001, specifically intended on reducing water level in the basin. This blowdown is typically performed to reduce tower salinity and/or total dissolved solids following extended operation. The reduction in these parameters occurs due to the makeup of fresh water to the system. Blowdown may also be performed to prevent overflow of the basin if the Cooling Tower water level reaches a high level such as the result of a series of rainfall events.

Cooling Tower water is treated to minimize biofouling and scaling of the system components. Sodium hypochlorite is normally added to the Cooling Tower during summer months to inhibit biological growth. A silica based anti-scalant is also added to minimize scaling in the Cooling Tower. The anti-scalant is added on an as-needed basis as determined by basin water sampling.

Alternate paths for this discharge:

0 No alternate paths anticipated Potential chemicals in discharge:

" Total Residual Chlorine - ocean water system input, Fire Protection System water from fill

• Sodium Hypochlorite - added to inhibit biological growth, seawater input, Fire Protection System water input

" Domestic water constituents - primary fill media, fire protection, washing, hydrolazing

• Rainwater constituents - rainwater that collects in open basin

" Suspended solids- all potential inputs to the cooling tower

" Chlorhexidine Di-Gluconate (Hydrosep) - emergency eyewash station biological growth inhibitor

• Sodium Silicate- scale inhibitor additive Proposed chemicals for future discharge:

None anticipated Maximum daily flow:

The current NPDES Permit does not contain a flow limit for Outfall 027. Average flows for Outfall 027 during the period April 2002 thru 2004 are 85,276 GPD. When placing the Cooling Tower in service and when removing the Cooling Tower from service approximately 50,000 to 200,000 gallons of Cooling Tower water is discharged to Outfall 001. In the event that the Cooling Tower is operated for an extended period, necessitating a blowdown evolution it is estimated that approximately 500,000 gallons of Cooling Tower may be discharged.

Outfall 027, p. 2

Discharge frequency:

Outfall 027 is considered a continuous discharge which occurs on an intermittent basis. Cooling Tower discharges may occur for a short period of time such as during swapover or a significant period of time during a blowdown following extended Cooling Tower operation.

" Fluid used during the regeneration of the Condensate Polisher demineralizer beds. The fluid is directed into the neutralization tank and then discharged to the Circulating Water System (Outfall 001). This wastewater contains acid and caustic wastes from the regeneration process as well as ionic constituents present on the resin from loading.

Rinse water from the Condensate Polisher demineralizers. Rinse water may be directed from the effluent of the demeralizer(s) to the neutralization tank. These rinses are required following regeneration of the demineralizer beds or pre-service rinses of the demineralizer beds. The rinse water source is dernineralized water.

System drainage for maintenance activities. Regeneration system components may be drained for maintenance activities. System drain water could contain acid and caustic as well as low levels of amines from vessels and piping. If maintenance needs to be performed on the Sodium Hydroxide or Sulfuric Acid tanks, their fluids may also be drained to this neutralization tank. Acid and caustic waste is neutralized to a pH of between 2 and 12.5 prior to discharge.

The Leased Makeup Water Treatment System (LMWTS) cleaning wastes are also directed into the neutralization tank. Cleaning is typically performed using Sodium Hydroxide and Sulfuric Acid and the wastes are generally neutralized in the water treatment system prior to discharge into the neutralization tank. Other infrequently used cleaning agents include Hydrogen Peroxide, Sodium Hypochlorite, and Sodium Chloride.

Discharge description:

The CPS was completed and initially operated in 2005 during the term of the current NPDES Permit as documented in the renewal application for the current NPDES Permit submitted in April 1998. It is an integral part of the Condensate System. The CPS is designed to remove dissolved and suspended impurities from the Condensate System that can cause corrosion and fouling of secondary components. The system is normally maintained in a standby condition and is placed in operation to remove secondary system contaminants to support plant start up or to remove impurities introduced by a condenser tube leak.

The basic system design consists of cation resin vessels, mixed bed resin vessels, pumps and associated equipment, and an external resin regeneration and waste processing system. The CPS is designed to accommodate approximately one third of the total condensate flow. The resin vessels remove the ionic constituents from the condensate system including the amines used for secondary chemistry control. The auxiliary regeneration and waste system is used to regenerate the resin for re-use and to discharge the regeneration and rinsate wastes. Sodium Hydroxide and Sulfuric Acid are used as regenerant chemicals.

Outfall 028A, p. 1

The discharges from the CPS System include: rinses of the system in support of plant start-up, periodic rinses during standby conditions, rinses of the resin vessels following regenerations, regeneration wastewater, sampling system and grab sample waste, system leakage, and system drainage for maintenance.

The CPS regenerant waste is collected in the neutralization tank and sampled prior to discharge. The tank volume is 32,000 gallons. The neutralization tank is recirculated via pumps installed in the tank and an eductor system to facilitate mixing. The tank is discharged at a maximum rate of 300gpm.

This wastewater contains low concentrations of acid and caustic wastes from the regeneration process as well as trace levels of ionic constituents present on the resin following regeneration. Backwash waste contains particulate matter that has been trapped in the demineralizers during system operation.

• Drain water from Condensate Polisher demineralizers and Low Conductivity system piping contents that may be drained for maintenance.

Discharge description:

The CPS was completed and initially operated in 2005 during the term of the current NPDES Permit as documented in the renewal application for the current NPDES Permit submitted in April 1998. It is an integral part of the Condensate System. The CPS is designed to remove dissolved and suspended impurities from the Condensate System that can cause corrosion and fouling of secondary components. The system is normally maintained in a standby condition and is placed in operation to remove secondary system contaminants to support plant start up or to remove impurities introduced by a condenser tube leak.

The basic system design consists of cation resin vessels, mixed bed resin vessels, pumps and associated equipment, and an external resin regeneration and waste processing system. The CPS is designed to accommodate approximately one third of the total condensate flow. The resin vessels remove the ionic constituents from the condensate system including the amines used for secondary chemistry control. The auxiliary regeneration and waste system is used to regenerate the resin for re-use and to discharge the regeneration and rinsate wastes. Sodium Hydroxide and Sulfuric Acid are used as regenerant chemicals.

The discharges from the CPS System include: rinses of the system in support of plant start-up, periodic rinses during standby conditions, rinses of the resin vessels following regenerations, regeneration wastewater, sampling system and grab sample waste, system leakage, and system drainage for maintenance.

The Low Conductivity Tank receives fluids from backwashes of the demineralizers and from activities involving transfer of the resin from various resin vessels in the system. The conductivity of the water in this tank is generally low as concentrated regeneration chemicals and concentrated amines are not present in the wastes.

The CPS low conductivity waste is collected in the Low Conductivity Tank and sampled prior to discharge. The tank volume is 32,000 gallons. The Low Conductivity Tank is recirculated via pumps installed in the tank to facilitate mixing and sampling. The tank is discharged at a maximum rate of 300gpm.

Section V, Intake and Effluent Characteristics Part V.D, List of Pollutantsfrom Form 2C, Tables 2C-3 and 2C-4 Discharge includes wastewater from the following sources:

Fluids used during rinses of the Condensate Polisher demineralizer beds after regeneration. The CPS resin is rinsed prior to placing the resin into the service vessels. The resin is rinsed to remove residual concentrations of Sodium Hydroxide and Sulfuric Acid remaining on the resin following regeneration. Rinse water is directed from the effluent of the resin vessels to Circulating Water System. The rinse water source is dernineralized water.

The discharges from the CPS System include: rinses of the system in support of plant start-up, periodic rinses during standby conditions, rinses of the resin vessels following regenerations, regeneration wastewater, sampling system and grab sample waste, system leakage, and system drainage for maintenance.

The CPS rinse discharge consists of water used to remove impurities from the demineralizers prior to their use for Condensate System clean up. The demineralizer impurities result from the regeneration of the resins with Sulfuric Acid and Sodium Hydroxide. The acid is used to reactivate the cation (positive ion) resin beads within the mixed-bed and cation bed demineralizers. The caustic reactivates the anion (negative ion) resin beads in the mixed-bed demineralizers. The regeneration process is started manually.

Upon completion of the regeneration, the demineralizer resin beds are rinsed with demineralized water. The rinse water is sampled to ensure compliance with the NPDES Permit effluent limitations and monitoring requirements.

The rinse water is directed to Outfall 001.

PART C - If you are a primary industry and this outfall contains process wastewater. refer to Table 2c-2 in the instructions to determine which of the GC/MS fractions you must test for. Mark "X" in column 2-a for all such GC/MS fractions that apply to your industry and for ALL toxic metals, cyanides, and total phenols. If you are not required to mark column 2-a (secondary industries, nonprocess wastewater outfalls, and nonrequired GC/MS fractions), mark "X' in column 2-b for each pollutant you know or have reason to believe is present. Mark "X" in column 2-c for each pollutant you believe is absent. If you mark column 2a for any pollutant, you mus provide the results of at least one analysis for that pollutant. If you mark column 2b for any pollutant, you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be discharged in concentrations of 10 ppb or greater. If you mark column 2b for acrolein, acrylonitrile, 2,4 dinitrophenol, or 2-methyl-4, 6 dinitrophenol, you must provide the results of at least one analysis for each of these pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater. Otherwise, for pollutants for which you mark column 2b, you must either submit at least one analysis or briefly describe the reasons the pollutant is expected to be discharged. Note that there are 7 pages to this part; please review each carefully. Complete one table (all 7 pages) for each outfall. See instructions for additional details and requirements.

PART C - If you are a primary industry and this outfall contains process waslewater, refer to Table 2c-2 in the instructions to determine which of the GC/MS fractions you must test for. Mark "X"in column 2-a for all such GCIMS fractions that apply to your industry and for ALL toxic metals, cyanides, and total phenols. If you are not required to mark column 2-a (secondary industries. nonprocess wastewater outfalls, and fractions), mark "X" in column 2-b for each pollutant you know or have reason to believe is present. Mark "X" in column 2-c nonrequiredGCIMS for each pollutant you believe is absent. If you mark column 2a for any pollutant, you mus provide the results of at least one analysis for that pollutant. If you mark column 2b for any pollutant, you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be discharged in concentrations of 10 ppb or greater. If you mark column 2b for acrolein, acrylonitrile, 2.4 dinitrophenol, or 2-methyl-4, 6 dinitrophenol, you must provide the results of at least one analysis for each of these pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater. Otherwise, for pollutants for which you mark column 2b, you must either submit at least one analysis or briefly describe the reasons the pollutant is expected to be discharged. Note that there are 7 pages to this part; please review each carefully. Complete one table (all 7 pages) for each outfall. See instructions for additional details and requirements.

PART C - If you are a primary industry and this outfall contains process wastewater, refer to Table 2c-2 in the instructions to determine which of the GC/MS fractions you must test for. Mark "X" in column 2-a for all such GC/MS fractions that apply to your industry and for ALL toxic metals. cyanides, and total phenols. If you are not required to mark column 2-a (secondary industries,nonprocess wastewater outfalls, and nonrequiredGC/MS fractions), mark X in column 2-b for each pollutant you know or have reason to believe is present. Mark "X" in column 2-c for each pollutant you believe is absent. If you mark column 2a for any pollutant, you mus provide the results of at least one analysis for that pollutant. If you mark column 2b for any pollutant, you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be discharged in concentrations of 10 ppb or greater. If you mark column 2b for acrolein, acrylonitrile, 2,4 dinitrophenol, or 2-methyl-4, 6 dinitrophenol, you must provide the results of at least one analysis for each of these pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater. Otherwise, for pollutants for which you mark column 2b, you must either submit at least one analysis or briefly describe the reasons the pollutant is expected to be discharged. Note that there are 7 pages to this part; please review each carefully. Complete one table (all 7 pages) for each outfall. See instructions for additional details and requirements.

Mark "X" in fractions that apply to your industry and for ALL toxic metals, cyanides, and total phenols. If you are not required to mark column 2-a (secondary industries,nonprocess wastewater column 2-a for all such GC/MS I outfalls, and nonrequiredGC/MS fractions), mark "X' in column 2-b for each pollutant you know or have reason to believe is present. Mark "X"in column 2-c for each pollutant you believe is absent. If you mark column 2a for any pollutant, you mus provide the results of at least one analysis for that pollutant. If you mark column 2b for any pollutant, you must provide the results of at least one analysis for that pollutant ifyou know or have reason discharged in concentrations of 10 ppb or greater. Ifyou mark column 2b for acrolein, acrylonitrile, 2,4 dinitrophenol, or 2-methyl-4, 6 dinitrophenol, you must provide the results of at least one analysisto believe it will be for each of these pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater.

FPL Energy Seabrook proposes the following changes to the current NPDES Permit requirements. Annotated NPDES Permit pages reflecting the proposed changes are attached following the change descriptions:

9 Condensate Polishing System Outfalls 028A, 028B and 028C (Proposed new addition to Permit)

FPL Energy Seabrook proposes to add three new outfalls to the NPDES Permit to establish Monitoring Requirements and Effluent Limitations for the Condensate Polishing System (CPS).

The CPS was completed and initially operated in 2005 during the term of the current NPDES Permit as documented in the renewal application for the current NPDES Permit submitted in April 1998. It is an integral part of the Condensate System. The CPS is designed to remove dissolved and suspended impurities from the Condensate System that can cause corrosion and fouling of secondary components. The system is normally maintained in a standby condition and is placed in operation to remove secondary system contaminants to support plant start up or to remove impurities introduced by a condenser tube leak.

The CPS and the three proposed outfalls (028A, 028B and 028C) are described comprehensively in Tab 2 with the Form 2C information. The proposed Monitoring Requirements and Effluent Limitations for the Condensate Polishing System (CPS) are attached with the annotated NPDES Permit pages.

9 Toxicity Testing Frequency Adjustment (Ref. Permit pages 19, 20, 21, 29)

FPL Energy Seabrook has performed quarterly Whole Effluent Toxicity testing since the effective date of the current NPDES Permit. Toxicity test results have been submitted each quarter with the Discharge Monitoring Reports. A table summarizing the results of toxicity testing 2002 - 2006 is attached. It is requested that the frequency of toxicity testing be adjusted from the current quarterly frequency to a semiannual frequency in accordance with Permit Part I.

E.1 "Special Conditions, Whole Effluent Toxicity Test Frequency Adjustment" which states the following:

The permittee may submit a written request to the EPA requesting a reduction in the frequency (to not less than twice per year) of required toxicity testing, after completion of a minimum of eight (8) successive toxicity tests of effluent all of which must be valid tests and must demonstrate acceptable toxicity. Until written notice is received by certified mail from the EPA indicating that the Whole Effluent Testing requirement has been changed, the permittee is requiredto continue testing at thefrequency specified in the respectivepermit.

Permit Changes, p. 1

Seabrook Station believes that the required condition for a frequency adjustment has been satisfied: "eight (8) successive toxicity tests of effluent all of which must be valid tests and must demonstrate acceptable toxicity". The attached table summarizes the results of 17 consecutive quarterly Whole Effluent Toxicity Tests, including 168 chronic and acute assays.

Approximately 95% of the reported assays (159/168) exhibit no toxicity in either acute or chronic tests, while 9 assays or approximately 5% indicate some degree of toxicity to the test species. The permit does not establish the threshold for acceptable toxicity; those values requiring reporting are "Report" only. While there have not been eight successive tests with no observed toxicity the data in total supports a general conclusion that the effluent is not toxic.

Seabrook Station proposes that the Whole Effluent Toxicity test frequency be adjusted to semiannual. The four quarterly discharge scenarios for Outfalls 025 A, B, C and D are proposed to be applied to the semiannual tests thus each of the four specified discharge scenarios will be tested every two years versus every year.

• Chlorine Transit Study (Ref. Permit page 21)

FPL Energy Seabrook performed six Chlorine Transit Studies during the term of the current NPDES Permit ("a minimum of twice per year for the first three years of the permit"). It is proposed that the current NPDES Permit requirement to perform Chlorine Transit Studies be removed based on the satisfactory completion and results of the six studies performed.

The results of each of the six studies were reported individually and were summarized in a final report submitted on May 16, 2005. The final report concluded: "the overall results of six chlorine transit studies demonstrates that the NPDES Permit Total Residual Oxidant (chlorine) limits, as measured at the Circulating Water System Discharge Transition Structure (Outfall 001), are sufficiently stringent to ensure that the New Hampshire chronic and acute water-quality standards for chlorine are met in the receiving waters. The six studies demonstrated that the residual chlorine concentration at a distance of ten feet from the diffuser nozzle was below the minimum detection level (0.05 mg/L) with one exception at 0.06 mg/L. At a distance beyond ten feet further significant reduction in chlorine concentration can be expected in the buoyant rapid mixing conditions of the thermal plume."

The six Chlorine Transit Study dates were:

FPL Energy Seabrook conducted a screen wash efficiency study on May 18, 2006 using dead fish as required by the current NPDES Permit. The results of the Screen Collection Efficiency Study are provided below. The study results indicate that the collection efficiency of the travelling screens and impingement sample collection process is very high consistent with impingement monitoring program assumptions. It is proposed that the current NPDES Permit Permit Changes, p. 2

requirement to perform screen wash efficiency studies be removed based on the results of this study.

• Outfalls 025C and 025D Oil and Grease Monitoring Requirement (Ref.

Permit pages 13, 14)

FPL Energy Seabrook proposes to revise the current NPDES Permit Monitoring requirement for Outfalls 025C and 025D oil and grease from the current "1/Batch" to "l/Quarter". The proposed change to quarterly oil and grease monitoring will make the oil and grease monitoring frequency for Outfalls 025C and 025D consistent with Outfalls 025A and 025B, currently monitored on a quarterly frequency. Outfalls 025C and 025D are consistently below the detection level for oil and grease as documented in the Discharge Monitoring Reports. During the term of the current permit all but three oil and grease analyses for Outfalls 025C and 025D have been below the detection level. The three oil and grease analyses that were above the detection level were less than one half of the NPDES Permit limit.

2006 025C and 025D oil and grease below detection level 2005 November 025D monthly average 2.0 mg/L (15 mg/L permit limit), daily maximum 9.6 mg/L (20 mg/L permit limit) 2004 025C and 025D oil and grease below detection level 2003 025C and 025D oil and grease below detection level 2002 July 025C monthly average 5.6 mg/L (15 mg/L permit limit), daily maximum 6.0 mg/L (20 mg/L permit limit) 2002 August 025C monthly average 1.3 mg/L (15 mg/L permit limit), daily maximum 3.1 mg/L (20 mg/L permit limit)

The performance of oil and grease analyses on Outfalls 025C and 025D by EPA Method 1664 results in the generation of radioactively contaminated hexane, a mixed waste. The oil and grease sample waste from these outfalls contains very low levels of radioactivity due to its presence in the outfall discharge at levels well within the effluent limits prescribed by the Nuclear Regulatory Commission. Hexane is present in the sample waste as it is used as a solvent in the analytical method. It is estimated that four gallons of mixed waste are generated annually.

In the interest of minimizing the generation of waste and the associated storage/incineration environmental risk it is suggested that the quarterly frequency of analyses is appropriate commensurate with the very low risk of an oil & grease discharge from the outfalls.

• Dynacool 1383 Antiscalant Concentration (Ref. EPA Letter dated January 27, 2004 and NHDES Letter dated January 30, 2004, NPDES Permit Attachment C, Bulk Chemicals)

FPL Energy Seabrook proposes to revise the current NPDES Permit concentration limit for the antiscalant product Dynacool 1383. The referenced EPA and NHDES letters approved the discharge of this product at a concentration of .1 mg/L at Outfall 001. The product is currently used to control scale formation in the Circulating Water Chlorination System and in groundwater removal systems designed to control groundwater infiltration in site buildings. To further Permit Changes, p. 3

enhance scale formation control, FPL Energy Seabrook proposes to increase the allowed concentration of Dynacool 1383 from .1 mg/L to 5.0 mg/L. The referenced letters document the very low aquatic toxicity of this "essentially non-toxic" product (96 hour0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> LC-50 for mysid shrimp > 5,000 mg/L). The recommended concentration (5.0 mg/L) is 0.1 percent of the mysid shrimp LC-50.

Biological and Water Quality Monitoring Program (Ref. Permit Pages 22, 25)

FPL Energy Seabrook proposes to revise the current NPDES Permit requirement to submit a description of the Biological and Water Quality Monitoring Program. A written description of the program was previously submitted on May 1, 2002. No changes to the monitoring program have been requested thus it is proposed that the NPDES Permit be revised to reference the current description of the monitoring program.

FPL Energy Seabrook proposes to revise the current NPDES Permit description of the report submittal requirements for the ongoing biological, hydrological and chlorination programs. The proposed change is for clarity and consistency with the requirement to submit the annual Environmental Monitoring Report by September 1.

SCREEN COLLECTION EFFICIENCY STUDIES SEABROOK STATION MAY 2006

Introduction:

The efficiency of the traveling screens and impingement sample collection process in retaining fish impinged on the traveling screens was estimated through a directed study on 18 May 2006 as a requirement of Seabrook Station's NPDES Permit. The purpose of this study was to estimate the percentage recovery of fish impinged on the traveling screens at Seabrook Station.

Seabrook Station makes use of a once-through circulating water system with an offshore cooling water intake for both the condenser cooling water and the plant service water. There are three offshore submerged intake structures which are located approximately 1.3 miles offshore and draw water from the western Gulf of Maine. The 19-ft ID intake tunnel conveys the water approximately 3.22 miles to an inland termination point which consists of a 19-ft ID vertical shaft and the transition structure. Adjacent to the transition structure is the circulating water pumphouse where the collection efficiency studies took place.

The water from transition structure enters the circulating water pumphouse and separates into three screenwells (Figure 1). Each screenwell contains stop log guides, a flow-through traveling screen and a 130,000 gpm circulating water pump that supplies circulating water to the condensers. The three screens are designated as I-CW-SR-IA, 1B, and IC. Each screen is 14-ft. wide and has %-in. mesh baskets. The water depth at the screens is approximately 43-ft.

below MSL. The screens have two operating speeds which are 5 feet per minute (fpm) and 20 fpm. Debris and fish are removed from the upstream (ascending) side of the screens with water sprays and are sluiced via a trough to a metal collection basket, where the debris is removed and the water drains into the intake transition structure. Fish impinged on the traveling screens are retained in the collection basket, which has the same mesh size as the traveling screens.

Impingement samples are collected twice per week to estimate the number of fish impinged annually.

All fish impinged on the traveling screens are assumed to be enumerated as part of the impingement enumeration process. However, there are several locations and processes where fish could be lost to the collection process. Although the nominal mesh size in the traveling screens is 3/8-in. it is possible that holes exist in the mesh that would allow fish to pass through into the cooling water system of the plant. Fish can also be lost to the system through "carryover" of fish over the top of the traveling screens. Fish also can become stuck in the trough that leads from the traveling screen to the collection basket. Finally, fish can be missed in the sorting process where the fisheries technician removes fish from debris in the collection basket.

Methods and Materials At 0650 hrs on 18 May, 100 fish were dropped through the stop log slots in the floor of the circulating water pumphouse to the surface of the water approximately 10 feet in front of traveling screen 1-CW-SR-1B (the middle screen). These fish were collected from previous impingement samples to ensure that they would be representative of the species composition and size of fish currently being impinged. Each fish was marked with a caudal fin clip to distinguish it from fish that were being collected as part of the concurrent impingement sample. Lengths ranged from 66-348 mm and species used were: alewife, cunner, grubby, rainbow smelt, sea raven, and winter flounder. The screens were washed at 0825 hrs and fish with caudal fin clips were removed from the impingement sample and counted.

Results and Discussion Of the 100 fish released, 98 were recovered yielding a screen collection efficiency of 98%.

Screen collection efficiency is often assumed to be near 100% and this study quantitatively evaluated this assumption. Screen collection efficiency is usually high at nuclear power plants where the traveling screens and associated troughs are well maintained and inspected as part of the cooling water system. The very good condition of the traveling screens and sluices at Seabrook Station contributed to the high screen collection efficiency. Furthermore, the relatively short distance and straight run of the sluice connecting the traveling screens and the collection basket also contributed to the high screen collection efficiency.

Clean Water Act Section 316 (a) and (b)

Certification FPL Energy Seabrook LLC has been authorized by the Environmental Protection Agency and the State of New Hampshire Department of Environmental Services (NHDES) to discharge from the facility, Seabrook Station, under the National Pollutant Discharge Elimination System, Permit No. NH0020338. The Seabrook Station NPDES Permit became effective on April 1, 2002, with an expiration date five years from the effective date. The Seabrook Station NPDES Permit and Fact Sheet documented the amended determinations regarding the thermal component of the discharge and the location, design, construction and capacity of the cooling water system intake structures made pursuant to the Clean Water Act Sections 316 (a) and (b). The Fact Sheet specifies the following requirement for amended determinations regarding Sections 316 (a) and (b) for permits being reissued.

Each time the permit is reissued (not to exceed 5 years), the 316(a) and (b) determinations are reviewed. The permittee must certify any changes in: (1) the facility discharge characteristics;(2) the waterway characteristics,and (3) resident or transient aquatic community. The permittee must then explain any differences identified and their impact on the local ecological community.

FPL Energy Seabrook LLC has submitted an application to renew NPDES Permit

.NH0020338. In support of an amended determination of compliance with Clean Water Act Sections 316 (a) and (b) FPL Energy Seabrook LLC certifies the following relative to the thermal component of the discharge and the location, design, construction and capacity of the cooling water system intake structures:

1) Clean Water Act Section 316 (a):

The thermal component of the discharge from Seabrook Station has not changed nor does the NPDES Permit renewal application propose any change in the current thermal limits as specified in the permit. Compliance with the NPDES Permit thermal limits and monitoring requirements is documented and reported on an ongoing basis as required by the permit in the monthly Discharge Monitoring Reports and in the annual Hydrological Monitoring Reports. A thermal plume comparative evaluation was submitted to the EPA and NHDES in June 1991, concluding that there was satisfactory agreement between plume model predictions and field data in terms of surface temperature rise isotherms, thermocline depths and plume pattern.

The impact of the thermal component of the discharge is rigorously assessed on an ongoing basis through implementation of the biological monitoring program required by the Seabrook Station NPDES Permit. The preoperational phase of this program was initiated in 1976 followed by the operational phase of the program initiated at the time of C.W.A. Certification, p. I

commercial operation of Seabrook Station in 1990. Annual reports documenting the biological monitoring program data, analyses and conclusions are submitted to the EPA, New Hampshire Department of Environmental Services and the National Oceanic and Atmospheric Administration, National Marine Fisheries Service. The annual reports continue to demonstrate that the operation of Seabrook Station has not adversely impacted the balanced indigenous populations of aquatic biota in the vicinity of the cooling water system intake and discharge structures.

Seabrook Station increased its electrical generating capacity in May 2005 by approximately 60 megawatts electric to its current capacity of 1221 megawatts electric resulting in an incremental increase in the heat rejected through the station's condensers.

The thermal component of the discharge is monitored on an ongoing basis by temperature instruments in the discharge area and continues to remain in compliance with the NPDES Permit receiving water temperature rise limit (ref: 2005 Hydrological Monitoring Report, SBK-L-06015, January 26, 2006). An additional increase in electrical generating capacity of about 40 megawatts electric will commence in November 2006. The ongoing monitoring program for the thermal component of the discharge will ensure continued compliance with the NPDES Permit receiving water temperature rise limit.

2) Clean Water Act Section 316 (b):

The location, design, construction and capacity of the Seabrook Station cooling water system intake structures has not changed nor does the NPDES Permit renewal application propose any change to these features of the cooling water system. Seabrook Station cooling water system flow is reported on an ongoing basis as required by the permit in the monthly Discharge Monitoring Reports.

The impact of the operation of the cooling water system intake structures is rigorously assessed on an ongoing basis through implementation of the biological monitoring program required by the Seabrook Station NPDES Permit. The preoperational phase of this program was initiated in 1976 followed by the operational phase of the program initiated at the time of commercial operation of Seabrook Station in 1990. Annual reports documenting the biological monitoring program data, analyses and conclusions are submitted to the EPA, New Hampshire Department of Environmental Services and the National Oceanic and Atmospheric Administration, National Marine Fisheries Service.

The annual reports continue to demonstrate that the operation of Seabrook Station has not adversely impacted the balanced indigenous populations of aquatic biota in the vicinity of the cooling water system intake and discharge structures.

Consultations with the National Oceanic and Atmospheric Administration, National Marine Fisheries Service were initiated in 1997 after a number of seals were taken in the Seabrook Station cooling water system. A Limited Take Permit application was filed by Seabrook Station in June 1997. Subsequently a Limited Take Permit and Letter of Authorization were issued by NMFS in July 1999. The provisions of the Limited Take Permit and LOA included enhanced monitoring, reporting and the requirement to design C.W.A. Certification, p. 2

and install a mitigation device to minimize or eliminate seal takes. Design and installation of a mitigation device was completed in August 1999. Additional vertical bars were installed on the intake velocity caps to reduce the bar spacing from approximately fourteen inches to five inches. The reduced bar spacing mitigation design has been completely successful in eliminating seal takes. In light of the proven effectiveness of the mitigation device design the Limited Take Permit was allowed to expire in June 2004.

FPL Energy Seabrook submitted on May 4, 2006, a Proposal for Information Collection (PIC) as required by CWA § 316 (b) Phase II Regulation, 40 CFR § 125.95 (b)(1). The Seabrook Station PIC is integral to this NPDES Permit renewal application. The PIC demonstrates that Seabrook Station's Cooling Water Intake Structure design is "best technology available" and meets the National Performance Standards of 40 CFR § 125.94 (b). The PIC also includes the information required by 40 CFR §§ 122.21(r)(2), (3) and (5) describing the source water body, cooling water system intake structures and cooling water system operation respectively. FPL Energy Seabrook intends to submit a Comprehensive Demonstration Study (CDS) subsequent to receiving EPA review comments on the PIC but not later than January 7, 2008. The CDS will supplement this NPDES Permit renewal application.
