Re Nalco H550 Good afternoon, As requested, I am providing information about Vermont Yankee's voluntary discontinuance of the use of the NPDES permitted biocide Nalco H-550. Since other products are available that work as well, and since the public was exceedingly focused on the gluteraldehyde contained in this product being released in the cooling tower mist, VY management discontinued its use. The last application occurred on July 18, 2005.

I've also attached a copy of the Station's final 2005 air emissions inventory report to the VT Agency of Natural Resources, Air Pollution Control Division, which shows the insignificant emissions from the cooling towers as compared to the State's action levels for Hazardous Air Contaminants.

Please don't hesitate to call if you have any questions or concerns with this information.

Request for Additional Changes to renewed NPDES Permit

Dear Carol,

As previously agreed, attached is the response to your informal information request regarding our pending NPDES renewal application. Briefly, Entergy Vermont Yankee completed testing on 30 November 2005 at outfall SN 001 (circulating water discharge) and at outfall SN 006 (north storm drain discharge). Vermont Yankee also collected control samples at the Upstream Station 7 location that were identical to the parameters tested for in the circulating water discharge and completed laboratory QC field blanks for several parameters. The field blanks were comprised of distilled water provided by the analytical laboratory. Grab samples were used for cyanide, total phenols, residual chlorine, oil and grease, fecal coliform, fecal streptococcus, TKN, ammonia nitrogen, and total metals. For all other parameters, hourly grab samples were composited over a period of six hours.

Enclosed are the analytical results from the four sampling locations. The sampling locations were identified to the laboratory as sample locations I through 4. Sampling location I was the circulating water discharge (SN 001), sampling location 2 was River water from the upstream Station 7, sampling location 3 was the Station's north stormwater outfall (SN 006), and sampling location 4 was distilled water from Endyne, Inc., which they in turn "blind" analyzed for specific parameters that Vermont Yankee requested.

p

--En tergy Additionally, attached is the information requested and as outlined in 40CFR122.21(r) for existing facilities. This includes a narrative description of the source water, the cooling water intake structure, and operation of the cooling water system. Also included are maps of the source water body and cooling water system drawings.

Vermont Yankee also understands that the ANR intends to include an extended submission schedule for Vermont Yankee's submission of a Proposal for Information Collection ("PIC") and a Comprehensive Demonstration Study ("CDS") as required by the Clean Water Act section 316(b) Phase II Rule. Entergy requested this extended submission schedule in a letter dated March 7, 2005, and Mr. Kooiker responded by letter on April 22, 2005 indicating that the PIC and CDS would not be required to be made a part of the NPDES renewal application and that a specific extended submission schedule would be considered as a part of the permit renewal process.

By way of this letter, Vermont Yankee also requests the following approved chemicals and corrections be included in the permit at the time of renewal.

On Pages 7 and 8, Part L4.15: List of approved chemicals in the NPDES Permit.

Please remove the following chemicals from the Permit:

Bulab 9027 and Inhibitor AZ8103 Ondeo Nalco H550 Replace Ondeo Nalco H550 with Nalco H-130, which does not contain gluteraldehyde (MSDS attached). Nalco H-130 is a biocide for use in service water as an alternative or in addition to bromine/chlorine. The use of this chemical would be controlled such that the discharge concentration to the Connecticut River of H-130, as with Spectrus NX 1104, would be maintained at less than 2.0 ppm.

Vermont Yankee requests the addition of permit language that would allow annual treatment of the Station's cooling towers with Prosan 24 or a similar product registered in Vermont. Prosan 24 is registered in Vermont as an antimicrobial for treating cooling towers by spray application using a 1:100 dilution that equates 0.02 lbs/gal of active product. We have requested and obtained approval from your office for this treatment in April 2006.

On Page 19, Part IV, Larval Fish: Because it is not always possible to collect larval fish samples on the same day each week, please revise wording from "Collect three plankton net samples on the same day in each week.", to "collect three plankton net samples on approximately the same day each week."

On Page 19, Part IV, Fish: Remove capitalization of "shad" and "salmon".

"--Entery On Page 20, Part IV, Anadromous Fish:

(1).

Because surface trawls are no longer required, please remove reference to them.

Increase beach seine quantity from twenty to thirty-two (32).

Finally, we appreciate your timely and complete application determination (30 September 2005 correspondence). We likewise appreciate your commitment to include an alternative schedule for meeting the new federal rulemaking regarding intake requirements (22 April 2005 correspondence). As you may be aware, Entergy Corporation currently is involved in the challenge to the new federal rule, as are several states; as such, Entergy respectfully must reserve its rights relative to the application of the federal rule, the rapidly evolving guidance and law in this area, and the facts above which will appear in any subsequent submissions pursuant to any federal rule under any alternative schedule.

Please do not hesitate to call if you have any questions with this information.

Sincerely, Entergy Nu lear Vermont Yr LLC n DeWald Environmental Specialist Samuel A. Wender IV Chemistry Superintendent

Narrative Description of Source Water Body, Cooling Water Intake Structure, and Operation of Cooling Water System iU.

Entergy - Vermont Yankee Vermont Yankee Nuclear Power Plant Vernon, VT 2.0 SOURCE WATER PHYSICAL DATA 2.1 Physical Description of Connecticut River in the Vicinity of Vermont Yankee The Vermont Yankee Nuclear Power Plant ("Vermont Yankee") is located 0.75 miles upstream of the Vernon Hydroelectric Dam (owned and operated by TransCanada), and 142.6 miles upstream from the mouth of the Connecticut River (the "River") on a reach known as Vernon Pool. The River in Vernon, VT is fresh water. Vernon Pool extends upstream from Vernon Dam approximately 25 miles to the base of the Bellows Falls Dam in Bellows Falls, VT and comprises 2,481 surface acres and 0.19366 billion cubic feet of water retained at a full-pond elevation of 220.13 ft behind the Vernon Dam (Normandeau Associates, 2004). Vernon Pool varies in width from approximately 400 feet to 3,000 feet and in depth from approximately 15 feet to 50 feet (average depth is 16 feet). The hydraulic retention time of Vernon Pool is approximately two days under Mean Annual Flow (MAF) conditions (-10,500 cubic feet per second or "cfs"), and about 16 days under regulated minimum flow conditions. Accordingly, for purposes of the §316(b) Phase II Regulations, the source water body type for the Station is "freshwater river or stream", since the average hydraulic retention time is less than seven days.

The annual cycle of ambient River water temperature is representative of the north temperate climatic zone. Mean daily River water temperatures remain near freezing from mid-December until early March, increase steadily from March until the seasonal maximum is observed during the period from late July through mid-August, and then decrease steadily until near freezing temperatures are reached again in mid-December (Luxenberg 1990). A significant portion of Vernon Pool is covered with ice during the winter months.

Connecticut River Discharge An annual cycle of River discharge is clearly evident at Vernon Dam, with a reported daily mean discharge that is at moderate levels (typically 10,000 cfs) from mid-October through mid-March, the peak daily mean discharge of 30,000 cfs or higher is observed during the April spring snow melt and runoff period, the annual minimum discharge (typically 5,000 cfs or less per day) occurs in late July through early September, and then discharge increases towards moderate levels again by mid-October (Luxenberg, 1990).

The River serves as the source water body for Vermont Yankee. River flows are highly controlled by hydroelectric generation activities both upstream and downstream of Vermont Yankee. There are nine hydroelectric dams and three storage dams on the mainstem River upstream of the Vernon Dam, and there are three hydroelectric dams and one pumped-storage facility downstream. Although storage in the Vernon head pond provides some flexibility of flow release from Vernon Dam, independent of inflow, the upriver hydro stations and Vernon Station are generally operated more or less in unison to maximize power output during times of peak power demand. This situation leads to two characteristic patterns of regulated River discharge: one of high and gradually varying flow, and one of frequent (two or more flow changes during each 24-hour period) cycling between lower and higher flows characterized by rapid transitions. The duration and magnitude of both the lower and higher flow during periods of daily cycling appears to be determined largely by the availability of water from upstream sources and may also be related to power demand.

I

Vernon Station has nine hydroelectric units that range in maximum capacity from 1,280 cfs to 1,970 cfs.

"Lower" flows are maintained by operating one unit and may likewise vary from 1,250 cfs (the permitted minimum flow if River flow is above 1,250 cfs) to 1,970 cf& "Higher" flows are generated by operating multiple units and may vary from 2,560 to 13,280 cfs. Typically, "lower" flows would be maintained for a period of several hours during each day, while "higher" peaking power flows would be maintained the rest of the time. However, under very low flow conditions, Vernon Station may operate continuously at or near 1,250 cfs, the FERC-licensed minimum flow if River flow is above 1,250 cfs, for several consecutive days.

3.0 COOLING WATER INTAKE SYSTEM DESCRIPTION Vermont Yankee was built in 1973 with mechanical draft cooling towers and operated with closed cycle cooling during its early years. §316(a) and §316(b) demonstrations were completed in 1978 following a series of tests between 1974 and 1978 that confirmed open cycle cooling during the (winter) period 15 October through 15 May assured the protection and propagation of a balanced, indigenous community of shellfish, fish, and wildlife in the River (Binkerd et al. 1978). Accordingly, Vermont Yankee has operated in an open cycle mode during the winter period under the conditions of each NPDES permit issued since the 1978 demonstration. Limited open cycle operations were subsequently permitted during the 16 May through 14 October period of each year beginning with the NPDES permit issued in 1991 following an additional 10-years of engineering, hydrological and biological studies culminating in successful §316(a) and §316(b) demonstrations (Downey et al. 1990).

The Vermont Yankee cooling water intake system consists of an intake structure and cooling towers that are configured to allow a continuous range of condenser cooling operations from closed cycle, to hybrid cycle, to open cycle. Closed cycle cooling occurs when the entire waste heat load from non-contact cooling in the condenser is dispersed to the atmosphere via mechanical draft cooling towers and the cooling water is recirculated back to the intake structure without passing into the River. Open cycle cooling occurs when the waste heat is removed by the flow of ambient River water that passes "once through" the condenser cooling system and is returned directly to the River. Hybrid cycle cooling occurs when a proportion of ambient River water passes through the cooling towers and is recirculated while the remaining portion is discharged to the River. The existence of these three operating modes means that Vermont Yankee's cooling water intake system operates with hourly, daily and seasonally varying intake flows using intake pumps, recirculation gates, and cooling towers. A general description of typical patterns of operation among these structures and operating modes is provided in the sections below.

3.1 Physical Description, Location and Depth of Cooling Water Intake Structure The cooling water intake structure (CWIS) at Vermont Yankee is located in a reinforced concrete bulkhead near the west shore of the River, in the impoundment area immediately upstream of the Vernon Hydroelectric Station, in the town of Vernon, Windham County, Vermont. The CWIS is located at the north side of the plant at approximately 42 degrees 47 minutes north latitude by 72 degrees 31 minutes west longitude. The CWIS is shared by the Circulating Water (CW) and Service Water (SW) systems, each within separate and isolated forebays. The CW system provides cooling water as a heat sink to condense the plant's main process steam after it is processed by the main generating turbine. The SW system provides cooling water as a heat sink for smaller heat loads generated by coolers in a variety of pumping equipment and heat exchangers within the plant. The SW portion of the intake structure also provides a suction path for the infrequently used Fire Protection System pumps. The Fire Protection System is used to protect the safety of the plant by providing a source of water for a variety of sprinkler systems throughout the plant, and is normally not operating but is maintained in standby readiness.

2

The CWIS extends from slightly above normal plant grade of elevation 252'-6"'down to the intake floor elevation 190.0', which is approximately 30' below normal River surface elevation of approximately 119.0' -220.0'. The intake forebay for the CW system is adjacent to but south of and separate from the intake bay for the SW system. The CW intake bay is designed to provide an independent flow path to each of three CW pumps through independent intake gates that may be raised or lowered provided that stop logs are installed in the pump forebay. The intake flow through any and all CW intake gate position combinations enters a common forebay servicing all three CW pumps. The SW intake bay is separated into two forebays. Each forebay contains two SW pumps.

3.2 As-Built Plan and Sectional Views of Intake Structure The following drawings provide plans and sections of the intake structure. These drawings show both the structure and major equipment and are included herein.

I G-191736 Intake Structure - Screens & Miscellaneous Steel G-200362 Circulating Water System Intake Structure - R - Sheet. 5 3.3 Fixed Screen (Bar rack) Description, Dimensions, Operation, and Debris Loading The Vermont Yankee CWIS has two sets of fixed screens (bar racks), with one set covering the CW intake and one set covering the SW inlet.

The fixed screens at the CW intake forebay are installed on the outer-most face of the intake structure.

Mechanical agitators are used to prevent surface ice from forming in front of these screens during winter months. Each fixed screen consists of 3 inch by 3/8 inch rectangular vertical bars on 3 inch centers across each intake gate opening. Although the fixed screens and gates extend all the way above the River surface for ease of maintenance, the actual opening in the concrete face of the intake structure through which CW enters the intake structure forebay extends from elevation 212'-0" (approximately eight feet below normal River elevation) to the bottom of the intake structure at elevation 190'-0". The size of the free open area across each of the three gates and fixed screens is nominally 22'-0" by 12'-0", or 264 sq.

ft. These fixed screens prevent the intake from clogging due to the buildup of frazil ice and/or large debris, and they also will exclude large fish from entering the CW forebay. There are no installed systems to remove large debris from these fixed screens. Any debris removal is performed manually by maintenance workers from installed platforms or boats. Opening the recirculation gate allows all or a portion of the CW effluent to return from the discharge structure to the CW intake forebay, allowing a slight head increase in the forebay above normal River level to aid in removing debris from the screens.

The design (maximum) water velocity through each CW fixed screen is nominally about 1.0 feet per second ("fps") with all three CW pumps operating in open cycle cooling mode. The actual water velocity through each CW fixed screen varies throughout the year from 1.0 fps down to 0.0 fps as the operating mode for the plant is changed from open cycle to closed cycle.

The SW forebay portion of the intake structure is immediately north of the CW forebay, and is separated from the CW forebay flow path by a reinforced concrete wall. A floating stop log is used as a barrier to 3

I

prevent surface debris' from entering the SW forebay. The entrance to each of the two SW pump bays is protected from debris intrusion by an independent fixed screen (bar rack). Mechanical agitators are used to prevent surface ice from forming in front of these SW fixed screens. Each fixed screen consists of 3 inch by 3/8 inch rectangular vertical bars on 3 inch centers across each SW pump bay opening. Although these fixed screens extend all the way above the River surface for ease of maintenance, the actual opening in the concrete face of the intake structure through which SW enters the intake structure forebay extends from normal River elevation of 220'-0" to the bottom of the intake structure at elevation 190'-0". The size of the free open area across each of the openings in the SW forebay and each fixed screen is nominally 30'-0" by 9'-2", or 275 sq. ft. These SW fixed screens prevent the service water intake from clogging due to the buildup of frazil ice and/or large debris, and they also will exclude larger fish from entering the SW forebay. There are no installed systems to remove large debris from these fixed screens.

Any debris removal is performed manually by maintenance workers from installed platforms or boats.

The design (maximum) water velocity through each SW fixed screen is nominally about 0. 1 fps during maximum flow summertime operations with all four SW pumps operating.

3.4 Traveling Screens Description, Dimensions, Operation, and Debris Loading The traveling water screens (furnished by the Rex Chainbelt Company of Milwaukee, WI) are vertical, single speed, single entry/exit mechanical devices providing a basic fish and debris handling system at the Vermont Yankee CWIS. These traveling screens are located at the in-board (west) side of the CW intake forebay and are recessed from the fixed screens and intake gates by about 55 feet. This enlarged CW forebay provides sufficient room for the recirculation water outlet to enter and mix with the ambient flow of River water passing through the fixed screens and intake gates. Each traveling water screen is installed between the CW forebay and the pump well of each of the three CW pumps (three screens). One traveling screen is installed between the SW forebay and each of the two SW pump bays. Each of the five traveling screens consists of 54 fiberglass basket elements that are chain driven in a continuous loop.

Each basket screen is formed from 0.080" diameter stainless steel wire cloth with 3/8" openings. Each CW traveling screen has a nominal design capacity of 120,000 gallons per minute (gpm) at a low water depth of 30 feet in the intake structure through a clean screen surface at a velocity of 1.96 fps. A single speed motor rotates the screens to provide for backwashing accumulated debris into a collection trough.

The concrete collection trough traverses the length of all five traveling screens and empties the backwashed debris and any impinged fish into a collection basket that is located on the north side of the CW intake forebay in between the CW intake and the SW intake structures. The perforated collection basket can be emptied manually as needed; while a 12" carbon steel drain pipe discharges accumulated backwash water back to the River. All fish and debris removed from the collection basket are placed in a dumpster and disposed of in a sanitary landfill off-site.

A portion of the SW pump discharge is diverted to the SW traveling screens through air operated isolation valves to provide backwash spray water for removing debris from the screen baskets. The spray system utilizes non-clogging, wear-resistant deflector type nozzles, designed to project overlapping fan shaped jets of spray water across the width of the screen so that all material picked up on the screen will be jetted off when the panels are ascending. Debris is jetted in a direction opposite the direction of flow of water in the intake structure. The design screen wash spray flow rate for each screen is 206 gpm, at a minimum of 80 pounds per square inch (psi) gauge pressure (psig).

The traveling screens are equipped with an automatic differential level control, and can be operated manually or in automatic mode. When in the automatic mode, each traveling screen will independently start and the backwash spray isolation valves will open when the screen wash line pressure is > 70 psig, and traveling screen high screen differential level (4 inches H-I20) is sensed by level detectors across the 4

I

screens. Once initiated automatically, a timer ensures a minimum of 10 minutes of backwash, which is sufficient to provide one full rotation of all screens, even if differential pressure across the screen has reduced below 4 in. H20.

4.0 COOLING WATER INTAKE SYSTEM DESCRIPTION 4.1 Circulating Water System Intake Pumps Description, Design Parameters, and Operation The total nomii-al design intake flow for the Vermont Yankee CW system is 360,000 gallons per minute.

The total nominal design intake flow for the SW system is 13,400 gpm. The Vermont Yankee CW intake structure terminates at three vertical, centrifugal circulating water pumps. Each single speed (350 rpm)

CW pump has a rated 86 feet of total dynamic head (TDH), and a rated flow of 120,000 gpm. The pump drivers are open, drip-proof, with induction motors rated at 1,250 HP. Two CW pumps are typically operated during the winter period. In the springtime, as River temperature rises and plant condenser vacuum increases, all three CW pumps are typically operated. The operation of three CW pumps continues throughout the summer and fall until River temperatures decrease sufficiently to allow the condenser cooling requirements to be met by operating two CW pumps.

4.2 Service Water System Pumps Description, Design Parameters, and Operation The Vermont Yankee SW system provides cooling water to plant equipment loads, such as the spent fuel pool, diesel generators, and various pumps and heat exchangers. Four vertical, 3350 gpm capacity, vertical wet-pit, SW pumps take suction from the SW intake forebay, downstream of the traveling screens. During winter operations, two SW pumps are operated. As River temperature increases or equipment heat loads increase, a third SW pump will be operated. During certain summer conditions with low River flow and high River temperatures, all four SW pumps may be operated. Although the SW intake forebay is physically separated from the CW intake forebay, the discharge of the SW system is combined with the discharge of the CW system.

4.3 Additional Pumps Taking Suction from the Common Intake Bay Although the primary intake flows are for the CW and SW systems, there are also periodic, minor flows drawn from the River through the SW intake forebay by the electric and diesel driven Fire Protection System pumps. These fire protection pumps are periodically tested for readiness, but are infrequently (or never) in continuous use. The flow from these fire protection pumps is considered process water and not cooling water for the purpose of calculating the percentage of Vermont Yankee's intake flow used for cooling. Two radiological waste dilution pumps are never used and are abandoned in place.

4.4 Biofouling Control Biofouling control is applied twice weekly at the Vermont Yankee CWIS when ambient River water temperatures are greater than 40°F. The application of biocides is performed during closed cycle operation, typically for one or two hours on the selected days. Chemicals, injection pumps, and controls for the biofouling control system are located in the intake structure chemical treatment shed. The CW system may be treated with sodium hypochlorite only or together with sodium bromide. The NPDES Permit requires monitoring, while treating the CW system and establishes discharge limits.

The SW system is chemically treated to reduce corrosion, the accumulation of deposits, and biological fouling, all of which affect the efficiency of heat exchanger components. The primary treatment to reduce biological fouling is through the use of an oxidizing biocide created by mixing sodium bromide and sodium hypochlorite solutions; however, other chemicals are authorized, with established discharge 5

1

limits, for use in the NPDES Permit. Oxidizing biocide treatment of the SW system in open cycle is permitted,. with no detectable oxidant in the CW system at the discharge structure.

4.5 Baseline Maximum Cooling Water Use Based On Pump Nameplates or Design Rated Capacity The baseline maximum cooling water intake flow for the Vermont Yankee CW system is nominally 360,000 gpm with all three of CW pumps running at 120,000 gpm each. The baseline maximum service water intake flow is nominally 13,400 gpm with all four of the SW pumps running at 3350 gpm each.

5.0 COOLING WATER DISCHARGE SYSTEM DESCRIPTION The cooling water discharge system is an integral part of Vermont Yankee's ability to operate the condenser cooling system in an open, hybrid, or closed cycle mode. There is a direct relationship between the amount of recirculation flow supplied from the discharge structure back into the CW intake forebay and a reduction in CW intake flow. The cooling water discharge structure and its operation control the flow of water to the cooling towers, recirculation to the intake structure, and discharge directly to the River. In general, Vermont Yankee's cooling water intake flow is withdrawn from the River in direct proportion to the amount of water discharged plus the water lost (evaporated) to the atmosphere during cooling tower operations. The paragraphs below describe the cooling water discharge structure, its operation, and its relationship to cooling water intake flow.

5.1 Circulating Water and Service water System Discharge Description, Design Parameters, and Operation The discharge of the CW system is directed to a discharge structure on the shoreline of the Vermont Yankee site, downstream (south) of the intake structure. Hydraulically operated sluice gates can direct the CW discharge to the River, to the cooling towers, or back to the intake structure through a 126" diameter recirculation line, or a combination of the three. The discharge of the SW system is normally combined with the CW system effluent inside the plant and is completely mixed prior to discharge to the River. During cold weather operations, the SW discharge is diverted to the deep basin (a 1.4 million gallon storage pool beneath the west cooling tower) to de-ice it, prior to the SW being discharged to the River. All CW and SW flows returned to the River are discharged over an aerating structure referred to as the discharge weir.

5.2 Cooling Tower Operations and Recirculation Flows Two 11 cell, cross flow, mechanical draft helper cooling towers are provided on the south side of the Vermont Yankee site. The cooling towers are rated for a total water quantity of 366,000 gpm, with a cooling tower duty of 2600 X 105 Btu/hr at an ambient wet bulb temperature of 751F. The cooling towers have been recently upgraded by the installation of 21 cells of 10 blade fans driven by 200 hp motors. One cell has been left with the prior 8 blade fan and 125 hp motor. The overall length of each cooling tower is 462'-7-1/2", with an overall width of 59'-6" at the top and 45'-6" at the bottom. To provide enough head to lift the CW effluent to the top of the cooling towers, three CW booster pumps are provided within the discharge structure. Each CW booster pump is a single stage centrifugal pump with a nominal flow of 122,000 gpm. The pump drivers are open, drip-proof, induction motors rated at 2,500 HP.

During winter operations, CW flows are discharged to the discharge structure forebay, where through manipulation of the discharge sluice gates, the flow is discharged in open cycle directly to the River over the discharge weir. Two CW pumps are operated, and no CW booster pumps are needed since the cooling towers are not in operation. SW is discharged from the plant to the cooling tower deep basin to 6

prevent icing, and from there flows to the discharge structure after bay and over the discharge weirto the River.

In early spring (typically March or April), as River temperature increases, the third CW pump is operated to maintain the correct condenser vacuum. No other changes to the pattern of CW or SW flows occur.

When freezing concerns no longer exist for the cooling tower deep basin, the SW discharge flow is diverted into the CW flow within the plant, resulting in combined SW and CW flow being released from the plant into the discharge structure forebay.

River thermal discharge limits become more restrictive on 16 May of each year, and these restrictions continue through 14 October of each year. The waste heat removed by the condenser cooling system is generally constant at 100% power throughout the year. However, as River flow rate decreases and River temperature increases during this summer (16 May - 14 October) period, the NPDES Permit thermal limits restrict the discharge flow of this non-contact cooling water, requiring more of the heat to be removed through use of the cooling towers, thus reducing the intake flow. Historically, by the end of May, it is necessary to operate the cooling towers in a helper mode to limit the heated discharge to the River. Cooling tower operation continues throughout most or all of this summer period and until the end of October of most years.

Two CW booster pumps are operated at the onset of cooling tower operations to supply the discharge of nominally two thirds of the CW and SW systems flow through both cooling towers in natural circulation mode, which then flows out of the towers at a cooler temperature, into the discharge structure afterbay, and finally is discharged over the discharge weir into the River. The remaining third of the flow discharges on open cycle directly to the River.

As River flow continues to decrease during the summer period and ambient River temperature increases, the third CW booster pump is started, causing all of the CW and SW systems discharge flow to be processed by the cooling towers on natural circulation before being discharged to the River.

As River flow continues to decrease and ambient River temperature increases during mid-July through mid-September of most years, cooling tower fans are started as necessary to remove the additional heat before the SW and CW discharge flow is discharged to the River. At this time the ambient wet bulb temperature becomes a third factor in addition to upstream ambient River water temperature and flow that determines the need for, and effectiveness of, heat removal by the cooling tower fans. This is because wet bulb temperature is a measure of humidity in the air, and the cooling towers work more efficiently when the air is dry and less humid than during periods of high wet bulb temperatures. The highest wet bulb temperatures are typically observed at Vermont Yankee during the same period as low River flows and warm ambient River water temperatures (i.e. mid-July through mid-September). When two towers operating with all fans running cannot maintain the discharge heat load from the condenser cooling system below that which the NPDES permit thermal limits allow, the recirculation line sluice gate is partially opened to divert part or all of the CW and SW heated effluent back to the intake structure instead of releasing it to the River.

As the fall approaches, River flow typically increases, ambient River water temperature decreases, and wet bulb temperature also decreases, allowing the recirculation gate to be closed to discharge the condenser cooling water directly to the River. Once the recirculafion gate is closed, cooling tower fans are turned off. Historically, this occurs around late-September or October of each year. When all three CW booster pumps are no longer needed to supply water to the cooling towers, one is secured and one third of the CW and SW flow is discharged to the River in hybrid cycle mode. When River flows have increased and River temperatures have decreased sufficiently, the remaining two CW booster pumps are 7

secured, and the SW and CW system flow is directed to the River in open cycle mode of operation. When winter approaches and freezing concerns exist, the SW effluent is again diverted to the west cooling tower deep basin to prevent icing.

During chlorination to reduce biofouling, the discharge structure gates are configured to place the plant in closed cycle operations. In closed cycle mode, 100% of the discharge flow is recirculated back to the CW intake forebay, and all of the suction of the three CW pumps is supplied by this recirculated water.

During closed cycle mode, cooling towers are placed in operation as needed, and there is no discharge flow to the River. Chlorination is performed infrequently. The plant is not returned to open cycle or hybrid operations until chemistry samples reveal an acceptable dissipation of the chlorine to within the limits established in the NPDES Permit. The normal chlorination duration is two hours a day, Mondays and Thursdays.

Vernon, VT 05354 Tel 802-257-7711 26 January 2006 Mr. Daniel Riley, Environmental Engineer Vermont Agency of Natural Resources Department of Environmental Conservation Air Pollution Control Division Building 3 South 103 South Main Street Waterbury, VT 05671-0402

Subject:

2005 Air Pollutant Emissions Inventory Report for Entergy Nuclear Vermont Yankee, LLC. Facility ID WM 2335.

Dear Mr. Riley:

Enclosed is Entergy Nuclear Vermont Yankee's air emissions inventory report for 2005.

Total air emissions from significant activities, which includes the house heating boilers and the waste oil burners, was 9.07 tons for the year. Vermont Yankee does not include emissions from the emergency diesel generators (A and B), the John Deere diesel, or the emergency diesel fire pump toward the total tonnage in this inventory report as these emergency generators, each of which operate less than one hundred hours per year, are considered insignificant activities under the State regulations.

The cooling tower particulate emissions calculations for the mechanical draft cooling towers are based on the drift and drift rate, and as in 2004, remain conservatively high.

The cooling towers operated for 2,149 hours0.00172 days 0.0414 hours 2.463624e-4 weeks 5.66945e-5 months during 2005. The operating hours were utilized in calculating the 2005 PM emissions.

PM Emissions (TPY) =Drift gpm x 8.33 lbs/gal x TDS x 60 min/hr x hrs/yr of operation x I ton/2000 lbs

=72.0 gpm x 8.33 lbs/gal x (62 lbs/1000000 lbs) x 60 min/hr x 2149 x I ton/2000 lbs The calculations for the 2005 emission data for cooling tower hazardous air contaminants (HAC) consider the miscibility of the product constituent and the water circulated through the cooling towers versus percentage of water loss through evaporation when the towers are running.

The circulating water flow through the cooling towers is approximately 360,000 gallons per minute (gpm), and based on the Final Environmental Statement Related to the Operation of Vermont Yankee Nuclear Power Corporation I

published by the Nuclear Regulatory Commission, 5,000 gpm is lost through cooling tower evaporation. The HAC emissions from the cooling towers are insignificant and do not exceed any action levels outlined in Appendix C of the Vermont Air Pollution Control Regulations.

Cooling Towers Pollutant Tons lbs/8 hours Action level (lbs/8hrs)

Particulate Matter 2.4 Dodecylguanidine Hydrochloride 0.001 0.002 0.025 Ethyl Alcohol 0.0004 0.001 2,330 Glutaraldehyde 0.008 0.015 340 Isopropyl Alcohol 0.0005 0.001 63 Total 2.41 This submittal does not include additional hazardous air contaminant (HAC) emissions inventory, as those would be associated with routine maintenance activities, such as painting and cleaning, and are therefore not subject to any State reporting requirements.

Please do not hesitate to call if you have questions or concerns with the enclosed information.

Sincerely, Entergy Nuclear Vermont Yankee, LLC Lynn DeWald Environmental Specialist 802-258-5526 Samuel A. Wender IV Chemistry Superintendent 802-258-5650 2
