NYSE1G ER OUESTION 1 NRC LETTER spril 23, 1979 Frovide the record high 1-hr wet bulb temperature associated relitive humidity at Syracuse for the period of record, 1955-1964. Also provide the average wqt bulb temperatures used to determine the average utscharge temperature.

Provide any updated data since 1964.

RESPONSE

For the 1955 through 1964 period of record at Syracuse, the maximum hourly wet bulb temperature af 78'T was observed on several occasions. The relative humidity associated with one of these 78'T observations which results in the maximum cooling tower blowdown camperature, is 45 percent. This observation for the month of June, as well as all other monthly maximum and monthly average vet bulb temperatures and associated relative humidities used to predict the cooling tower bicudown temperatures reported in Table 5.1-1, New Haven-Nuclear, are listed in Table Q3-1-1.

All vet bulb te..eratures and associated relative humidities covering a period of record from 1945 through 197~ vere similarly evaluated to deistmine monthiv averages, and to select the monthly vet bulb temperature and associated relative humidity which results in the highest cooling tower blevdown temperature. These updated data are also presented in Table Q3-1-1. All data reported prior to 1965 represent hourly readings; the 1965 through 1975 data represent observations taken once every 3 hours3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months .

For the updated period of record covering 1945 through 1975, there have been seven observations of 80*F set bulb temperatures (e.g., uhree observations on June 29, 1945; one observation each on August 25, 1947 and July 20, 1972; two observations on August 9, 1973), which are higher than those indicated in Table Q3-1-1. However, in selecting the ccabinations of meteorological data uhich result in the maximum cooling tower bloudown temperatures, all vet bulb temperatures and associated relative humidities are evaluated by using the conceptual cooling tower performance curves. In these curves, cooling tower blevdown temperature increases with increasing vet bulb temperature and decreasing relative humidity. Accordingly, the 80'T observations are not listed en Taole Q3-1-1, since the relative humidities associated with these observations resulted in lower cooling tower blevdown temperatures than the combinations of vet bulb temperatures and associated relative humid 4*ies which are listed in Table Q3-1-1.

NYSE8G ER OUESTION 3 NRC LETTER April 23, 1979 What is the exact distance between the centers of the natural draft cooling towers? How is plume merging treated in the plume ri e and drift deposition models?

RESPONSE

The dist'nce between the centers of the natural draft cooling towers is 654.7 meters (2,148 ft). The cooling tower models for plume rise and drift deposition do not deal with plume merging of natural draft towers, but the ground-level impacts are modified to reflect the increased load caused by multiple units and towers. In the development of the model ENVIRN, it was considered that to neglect multiple plume merging, and thus not account for plume rise enhancement. vould constitute a conservative assumption since higher values would be estimated for ground-level impacts. In the case of deposition, the magnitude of the impacts have been considered more significant than the downwind location. To account for a multiple source of drift, the deposition resulting from one unit ha. simply bean multiplied by 2 - the number of units. The totaA dissolved solids for one unit were used as input in the production run of ENVIEN so that the drift and deposition were assumed to be doubled when the two units were censidered. In view of the fact that the drift from multiple towers is dispersed over a wider area than that from a single tower, doubling the deposition values from a single tower and unit is conservative.

Amendment 3 Q3-3-1 June 1979 5GE017

NYSERG ER OUESTION 4 NRC LETTER April 23, 1979 What are the _riteria for plume visibility used in the plume model?

RESPONSE

The criteria for the cooling tower plume visibility in ENVIRN are to a certain extent dependent upon what plume parameter is being calculated. There are some common criteria for all visible plume parameters, but some differences also exist in order to reduce calculations or to present more specific information. The criteria distinctions are explained below. Basically, in order for the plume to be visible, the plume must be supersaturated. Hence, the water vapor concentration in the plume mrst exceed the saturation value for a given temperature at the specified downwind distance. When the volume flux of the plume increases to an extent that the water vapor content (d x) becomes less than the saturation value at plume temperature the plume is no longer visible. Hence, the plume water vapor density and tamperature change with downwind distance as a function of the volumetric flow rate c the plume across the predicted plume cross section (Environmental Report Section 6.1.3.2.3).

Certain differences exist in visible pluma criteria for fogging and plume length calculations. When the model ENVIRN tests for ground-level fog, the fog subrontine calculates the total ambient and plume water vapor density at the plcme temperature for the specified receptor distance and determines visibility reduction at ground level (if any) fron a formulation reported by Gecrge. In the case of visible plume length calculations, the plume vatar rapet censity is tested against the saturation value at the ambient temperature rather than the saturation value at the plume temperature. The purpose of this modification is to enable the visible plume length to be calculated in one step, rather than require an iterative process which would calculate the plume temperature and water density at incremental downwind distances until the water vapor concentration decreases below the saturation value.

The assumotion that the visible pluma disappears when the water vapor density falls below the saturation value at the ambient temperature is conservative.

The plume temperatute is always higher than the ambient temperature at the same dovr. wind distance and, in reality, causes the visible plume to evaporate at a shorter distance since the saturation value of water vapor density is higher within the plume. It should be noted that any level of visibility reduction constitutes a visible plume for the plume length calculation while, for ground-level fogging to be reported, the plume must reduce the existing ground-level visibility to less than or equal to 0.25 mi (heavy fog).

NYSE8G ER OUESTION 5 NRC LETTER April 23, 1979 Present av-11able validation for the plume, drift, fogging, and icing models.

RESPONSE

The mo d e .' ENVIRN, which predicts plume length, fogging, drift, and icing, has not been formally validated with field data. At the time of the initial model development (1972-1975), only limited field information was available for natural draft towers. The only naturmi draft tower plume data emanated from IVA's Paradise Steam Plant where plume length and height measurements were taken along with meteorological measurements < ',2 ' . Deposition data had been recorded at Forked Riveri8* . The only attempt to compare quantitative values from field studies with the model results occurred when the final plume height values, as estimated from a formulation used in the model, was informally hand calculated by Dr. James Austin'28, and checked against the field results. The model, as used for the natural draft tower, mainly used the formulations and assumptions of various investigators found in References 4 through 7.

Some modifications were implemented by Dr. Austin and the UEtC staff (ER Section 6.1.3.2.3 and Appendix 6.lA, Amendment 1). The modifications include the assumptions that:

1. A plume entrainment coefficient of 0.8 to calculate the plume itse coefficient in Briggs' plume rise formula better predicts the final height.

2. A plume entrainment coefficient of 0.3 for the Yz term in ER Equation 6.1-41 provides a more reasonable plume radius value than a coefficient of 0.6 and is also more conservative with respect to plume length.

3. Atmospheric cispersion dominates after final plume rise so that the plume cross-section changes from a circular to an elliptical shape dependent upon stability.

4. The plume has no ground level fog /i e impacts when the windspeed at the tower top is less than 2.1 m/sec'-).

5. Salt droplets, normally expected to fall before final plume rise, deposit at receptors immediately beyond final rise, yielding more conservative offsite deposition values.

The results of estimated impacts for the New Haven site are such that any ENVIRN model inaccuracies are not expected to compromise the conclusion that the cooling tower impact is insignificant.

Amendment 3 Q3-5-2 June 1979

NYSL8G ER OUESTIOE_6 NRC LETTER April 23, 1979 In which specific areas of calculation are cloud cover, visibility, ceiling height, and precipitation used?

RESFONSE Hourly observations of cloud cover, ceiling height, visibility, and precipitation have been incorporated into the ENVIRN model in order to more accurately characterize cooling tower impacts in conjunction with naturally occurring conditions. Certain natural conditions provide insight on which to base refinement of the ENVIRN predicted impacts. For example, there is no known case in which a cooling tower plume has descended below a cloud base once the lever plume edge has risen above the cloud base. Therefore, no fogging or icing is expected in conditions where broken or overcast skies are reported and unere the lower plume edge ascends above the ceiling height.

Visibility and precipitation parameters are used in the fog / ice model to distinguish between man-made impacts and natural events. The ambient and plume water vapor concentrati?a= are summed and the visibility is calculated as a function of the water vapor concentration. Cooling tower fogging will not be predicted to occur if natural heavy fag (visibility 50.25 mi) already exists. On the other hand, if the cooling tower plume plus the naturally occurring visibility conditions reduce total visibility to 0.25 mi or less, cooling tower fogging is predicted to occur.

Precipitation ic utilized in the model to determine whether the cooling tower plume is producing ice on surrounding objects at ground level. If precipitation already exists when the ambient temperature is below freezing (i.e., freezing rain), the icing from the cooling tower plume is considered to have negligible added impact. Therefore, hours of man-made icing from cooling tower plumes are discarded during naturally occurring freezing rain or drizzle.

Amendment 3 03-6-1 gri 1 June 1979

NYSE1G ER OUESTION 7 NR; LETTER April 23, 1979 What is the reference for the table of values of p in Eq (6.1-38) on page 6.1-597

RESPONSE

The power extrapolation law for the wind profile in ENVIRN utilizes stability-dependent exponeatial values of p taken from the EPA model RAMR. The model RAMR is the rural version of the EPA air quality model and so the stability-dependent values of p are cc; idered valid for the New Haven site. Ine only revision in ENVIRN has been to retain a value of 0.55 for p during stability class G. RAMR does not ha.dle class G. The use of the 0.55 value for stability class G is based upan an assumption that the wind profile does not differ significantly from that in stability class F. The table of p va!ues for rural sites is contained in Reference 1.

Amendment 3 Q3-7-1 June 1979

NYSERG ER CUESTION 8 NRC LETTER April 23, 1979 What is the reason for using 3 cycles of concentration in drift calculations instead of the more critical 6 cycles of concentration?

RESF01 tL The cooling tower environmental impact model ENVIRN has been designed to estimate long-term average drift impacts and not to predict transient conditions. The cooling tover salt deposition and drift values presented in ER Section 3.1.4 are based upon average cooling tower operating characteristics and a 1-year onsite meteorological data base. The cooling tower makeup water concentration using thrae cycles reflects the long-term average concentration. Therefore, to estimate the long-term average ecoling tower drift impacts, three cycles of concentration in the makeup water have been considered appropriate to use as model input instead of the six-cycle transient value.

Amendment 3 Q4-1-1 ,

June 1979

NYSEL3 ER OUESTION 2 TRC I.ETTER Hay 25, 1979 Have other industrial permittees on the Mohawk experienced difficulties with their permits because of the revocability of those permits?

RESPONS';

In general, the New York State Department of Transportation (DOT) does not grant permits for consumptive water use. The water use permits that they have branted are for a specified amount of water withdcaval, all of which is assumed to return to the river eventually. To the Applicant's knowledge, none of these permits have been revoked for their effect on flows or water level.

Amendment 3 Q4-2-1 June 1979

NYSE&G ER OUISTIONS 3 AND 4 NRC LETTER May 25, 1979 Uhat information is available from either historic flow rates or historic navieation needs which would indicate a real risk of permit revocacion?

Do you expect that such revocations woul; be temporary? Hov frequently and for what length of time do you estimace such revocations would occur?

2(SFONSE The Department of Transportation (DOT) has stated that if the flow in the Mohawk fallr to 610-650 cfs, they begin to have problems with ware- levels.

Data at Little Falls, N.Y., indicate that a 1-day lov flow of 570 cfs has a recurrence interval of 5 years, a 7-day low flow of 610 cfs has a recurrence interval of 10 years, and a 30-day low flow of 640 cfs has a recurrence interval of 20 years. Thus, for the length of time and at the recurrence intervals given, there vill be a marginal amount of flow for navigation.

A power station, such as the one pccposed for New Haven, would consume approximately 66 cfs under vorst case meteorological conditions. Uith this consumptive use, a flow of approximately 676-716 cfs will be required to meet nav_gation needs. The recurr- r inter'ca) tor lov flows in the 676-716 cfs range would be approximately 2 yeirs for the 1-day lov flow, approximately 3-5 years for the 7-day lov frov, and approximately 7-11 years for the 30-day lov flow.

of Transportation. The Applicant has no information on the costs involved o' the methods which could be used in reducing leakage from the locks and dams.

Amendment 3 Q4-5-1 June 1979

NYSE8G ER OUESTION 6 NRC LETTER May 25, 1979 What inquiries have you made into potential agreements and/or other provisions for Department of Transportation releases from the reservoir during periods of lov flow? What indication do you have of the likelihood that circumstances would exist during plant operation that would prevent such releases sufficient to avoid tavocation of an electric utility's water use permit?

PESp0NSE The Applicant and its consultant have discussed with the Department of Transportation (DOT) several schemes of flow augmentation including the possible expansion of Hinckley Reservoir, changes in the operation of Hinckley Reservoir, and building a reservoir solely for plant water needs.

Department of Transportation policy states that regardless of thu flow augmentatien scheme used, navigation needs are the primary concern and all other concerns are secondary. In addition, regardless of any agreements made with the Dor, they cannot issue an irrevocable water use permit. The revocable permit which the DOT could issue might be revoked in times of lov flev due to a lack of surplus water. The risks assceiated with developing a multi-billion dollar power plant on a water body where the permit for water supply could be revoked for reasons not under control of the owner of the plant were not acceptable. This is especially true considering there are other available sites not subject to such conditions.

Amendment 3 2.1-viii June 1979

NYSE8G ER NEW HAVEN-NUCLEAR This will be chiefly due to increased development in the Syracuse Standard Metropolitaa Statistical Area, which is a major user of water from the Lake.

2.1.3.8 Ground Water Throughout central New York State, ground water is a major source of water for domestic, agricultural, and industrial needs. Although secondary to surface water in quantity consumed, ground water supplied approximately 70 percent of Oswego County's total 1970 population of 100,897(78,75,'"> .

The use of ground water in Oswego County is through both public water systems and individually owned wells or springs. Out of the nine existing municipally owned public systems, seven u2ilize ground water (Table 2.1-45) and two systems, Oswego on Lake Ontario and Cleveland on Oneida Lake, utilize surface water Ground water consumption in the seven systems presently amounts to 5.32 mgd or 35 percent of the total water consumed in public systems. This is used primarily for domestic purposes and supplies approximately 25,140 people (725 Industrial consumption accounts for only 30 percent of the ground water used'78'. Figure 2.1-17 shows the location of each public system with respect to the site.

The remainder of Oswego County's populace not connected to public water supplies, app *oximately 46,000 people, must rely on individually owned supplies. These are primarily drilled or dug wells; however, water is occasionally drawn directly from a spring or nearby stream. Water demands on individual supplies in Oswego County can vary from 100 gpd for small families up to 4,000 gpd for the larger farms'7.

Ground water use in the site vicinity is entirely by individual supplies. The extent of this use was determined by a well survey completed as part of the New Haven site study in February 1978. This study covered an area within a 1.5-mi radius of the proposed site. Table 2.1-46 summarizes the survey data and Figure 2.1-18 locates each well. The wells located within the proposed site boundary will be purchased. There are no uses planned for these wells during the operation of the station.

The survey showed that approximately 6a percent of the owners have drilled wells (6-inch or 8-inch diameter), approximately 40 percent have dug wells (36-inch to 48-inch diameter) and only a few have driven wells or use other sources. The drilled wells range up to 142 ft deep and usually drav vater from the top 30 ft of the Oswego sandstone. Dug wells vary from 10 to 40 ft in depth and are predominantly in glacial till. A few dug wells in the village of New Haven benefit from a local deposit of outvash sands and gravels. In addition to wells, Table 2.1-46 indicates that three owners drav vater directly from Butterfly Creek, one owner uses a spring, and four have spring fed ponds used only for watering livestock. No other surface water users have been identified within the 1.5-mi radius of the site.

The total average daily ground water consumption by the wells within the turvey area is roughly 150,000 gpd, based conservatively on 500 gpd per family Amendment 1 , , 2.1-29 {yhfle March 1979 565E-e8

NYSEaG ER NEW HAVEN-NUCLEAR plus 3,000 gpd for the few large dairy farms (Well Nos. 123 and 246). There is no known use of ground water for irrigation in the vicinity.

The arr = that could be affected by any station effluents would be along the northerly ground water flow path between the site and Lake Ontario. The nearest wells along this path are of both the drilled and dug varieties (Nos. 230, 233, 241, 242, 243, 244) and will be over one-half mi from the station structures. In addition to the above wells, the area potentially affected by effluents also includes the seasonal lakeside communities of Demster Beach and Hickory Grove, 2.3 mi to the north. There are no public ground water systems down gradient of the site nor do any of the northerly flowing streams which pass through the site (Catfish and Butterfly Creeks) approach any public system. The nearest system is in the Town of Mexico which is supplied by three wells located almost 5 mi to the southeast of the site.

Sections 4.1.8 and 5.6.3 analyze the extent of potential station influence on the local individual wells in greater detail.

The possibility of present or future ground water consumption exceeding the annual recharge is improbable. Within the 7 sq mi area encompassed by the well survey, the annual ground water recharge is approximately 1,131,400,000 gal, based on a mean annual precipitation of 36.5 inches (Section 2.3.1.3.4) 75 percent loss due to surf ace water runof f and evapotranspiration' ' ' , ' .

This large recharge could not easily be exceeded by the future consumption.

Based on an estimated population of 3,141 for New Haven in the year 2000'5' and assuming a conservative per capita use of 200 gallons per capita daily, the average daily consumption would be only 0.63 mgd or 20 percent of the ground water recharge. Another factor which ensures low future consumption in the site vicinity is that the low yields of the underlying aquifers (Section 2.4.2) limit all local wells to the small domestic variety. Large industrial or public water systems could not be developed in the immediate site area without depending heavily upon a surface water source to rerpiv their needs.

2.1.3.9 Floods l Section 2.4.1 describes streams in the site area and their watersheds.

These streams flow in a northerly direction and are perennial with a marsh or swamp as source. Butterfly Creek has : drainage area of 6.3 sq mi above the site, with 0.47 sq mi in swamp or marsh. The average slope of Butterfly Creek is 16.4 ft per mi.

The tributary of Catfish Creek, which lies immediately to thr west of the site and is identified as tributary FW in this report, has a Jrainage area of 1.02 sq mi above the site, of which 0.16 sq mi is swamp or .narsh. The average slope of this stream is 71 ft per mi.

l Another tributary of Catfish Creek, identified as FE, flows through the site and will be diverted to near the site's western boundary. The drainage area of the diverted stream above the site is 1.06 sq mi, with the source being a l 50-acre (0.08 sq mi) marsh located 1/2 mi south of the site. The diversion Amendment 3 2.1-30 rg j

e June 1979

NYSEEG ER NEW HAVEN-NUCLEAR channel has a trapezoidal cross section and is designed for flow greater than the 100-year flood flow. Approximately the first 1,700 ft to the north of State Route 104 drop quickly to below site grade with a slope averaging approximately 28 ft per 1,000. This section is excavated in bedrock or lined with riprap, where necessary, and has a 20-ft bottom width for the first 1,500 ft, and 2:1 side slopes.

After a 200 ft transition section, the next approximately 2,300 ft are lined with riprap with a 50-ft bottom width sloping 1.8 ft per 1,000 ft and 5:1 side l

slopes. The remainder of the channel, before it rejoins the existing stream bed at the northwest corner of the site, is grassed with a 60-ft bottom width and a 5:1 side slope. The bottom slope of this channel segment is 2.7 ft per l 1,000. The channel diversion facilitates the development of the site by removing the source of flooding. There is no net area saved from flooding since the area gained by relocating the stream approximately equals that required for the diversion channel.

Table 2.1-47 gives the 50- and 100-year recurrence interval flood flows.

These were obtained frcm runoff predictions of 50- and 100-year precipitation evcnts through the use of the HEC-1 computer program5) . The Clark unit hydrograph procedureh' was used with the time of concentration and storage coefficients presented in Table 2.1-48. These values were obtained using regression equations presented in USGS water supply paper, "Model Hydrographs"'. Rainfall amounts were not reduced to account for initial loss or infiltration. Unit hydrographs for the Catfish Creek Tributary TE, FW, F, and Butterfly Creek are shown in Figures 2.1-23, -24, -25, and -26, respectively.

The 50- and 100-yr floods produced nearly the same degree of flooding on these streams. Figure 2.1-19 shows the water levels for the 100 yr flood.

Figures 2.1-20, 2.1-21, and 2.1-22 show the water surface profiles for these streams.

The water levels and water surface profiles were computed by using HEC-2 rei, Representative cross-sections for the natural stream portions within the drainage basins were determined from Figures 3.1-1 and 3.1-2 and from USGS topographical maps'. The Mannings "n" values used in the HEC-2 analysis were conservatively selected to be 0.06 for the natural stream sections, 0.033 l

for the diverted stream sections that will be lined with riprap, and 0.1 for those sections of the diverted stream that will be seeded with grass.

Pastured areas on the site have been typed as either pasture or improved pasture. Scattered trees and shrubs are present in those fields typed as pasture. Improved pasture denotes fields in which no trees or shrubs occur.

In addition, livestock are periodically pastured in the various forest and shrub cover types which are also shown as pastured on the cover type map.

The meacow and some open field types of Table X-1 have been combined into a single hay field type. This type includes all areas which are usually moved for hay but not plowed annually. Wetland types on the site include the open water and swamp types. The former occurs as scattered small man-made ponds.

There are two svamp type areas in which standing water is present most of the year. Frimarily open herbaceous and shrub vegetation is found in the svamp type along with numerous dead hardwood trees and some eastern hemlock.

The residential / commercial type designation identifies those areas of the site occupied by residential and commercial buildings and their surrounding areas (including storage) which are maintained by man's activities.

Otner types identified on the map are hedgerovs, abandoned orchards, corn and grain fields, transmission line right-of-way, and a private airstrip.

The major cover of the site occurs as either shrub or shrub / sapling types, totalling 38.5 percent of the site area. Open fields, which also have a woody component, account for an additional 7.6 percent. The active agricultural cover type (i.e., hay, corn, grain, pasture, and improved pasture) account for 33.4 percent of the site area; Tallow agricultural land contributes an additional 1.2 percent. Of the active agricultural types, Hay contributes the largest portion. Residential / Commercial land constitutes 5.2 percent of the area.

2.2.1.3.2 Land Use in the Recent Past The distribution of cover types on the site in 1956 is shown in Figure 2.2-5.

This mapping was done through interpretation of 1956 black and white aerial photos of t'ae site area.

In 1956 agricultural lands occurred over 47 percent of the s.te, with hay fields accounting for 42 percent of this total. In 1977 agricultural lands l occurred over 35 percent of the site, with hay fields accounting for 20 percent of the total. Open fields were also more widespread in 1956, occurring over 14 percent of the site area compared to 7 percent in 1977.

This 7 percent reduction in field communities is largely due to the abandonment of hay fields over the past 20 years, and the subsequ'nt development of shrub communities. This change has resulted in an increase in Amendment 3 2.2-16 Db~

p. usually most abundant at depths between 100- and 300-ft in the Great Lakes'82**, and generally live at or near the bottom. Lake trout seldom remain for extended periods at temperatures greater than 18.3C, preferring temperatures near 10C'82*'. The warming of surface waters usually restricts them to deep watot in summer.

Considerable information is available o r. the biology of lake trout, 2nd excellent accounts of its life history have beer provided by several authorsi ,82',88o,88. Lake trout spawn once a year, usually in late summer or fall. The date depends on a variety of factors, which apparently include physiological differences among races, physical characteristics cf the lake, latitude, weather conditions, and water temperatures. Temperatures of 8.9 to 13.9C have been reported at the time of spawning. Most spawning occurs in October, but the breeding season extends into November in the Great Lakes and may continut for a month or morei'288 The typical spawning grounds of lake trout are wave- or current-swept rocky shoals at water depths ranging from less than 1- to 100-ft. Spawning is random, and no care is given the eggs which sink into crevices among the rocks. Considerable variation has been observed in spawning periods and habitat among different races.

Christie <2,o' reported that spawning in eastern Lake Ontario was confined to a few well-known lake shoals. Most lake trout return to the same spawning grounds each year.

Gill netting was conducted in northeastern Lake Ontario by the NYSDEC in October and November 1977 to determine oossible spawning grounds of lake trout'82. Relatively large numbers of ripe and spent adults were captured in a small shallow area on the northeastern end of Stony Island, which is located approximately 25-mi from the Mexico Bay area. The shoal area had previously been a popular beach seining location for fishermen seeking native stocks of lake trout during years prior to their near extinction. This indirect evidence strongly suggested thar lake trout spawned on a historic Lake Ontario spawning shoal for the irst time since the demise of na*ure stocks nearly 30 years ago'82. Fry trap sampling on the shoal was conducted by the NYSDEC in early spring of 1978 to provide direct evidence of spawning success; however, many of the traps were disturbed by ice and no fry were captured'882) . The nearest documented spawning site in the vicinity of Mexico 8 Bay was the shoal area of Stony Island'82. There is no indica: ion that the Mexico Bay study area is a lake trout. spawning area.

The number of eggs produced by lake trout often varies widely among individuals of the same size, but the average number increases with .; reasing size of the fis't. The number spawned during a season ranges from ateut 1,000 for small fish da inland lak- to as many as 18,000 for large lake trout from the Great Lake s ' 8 2 ' ' . Age V females collected during 1977 Lake Ontario netting activities by the NYS)EC produced between 3,854 and 9,391 eggs, with an average of 5,730 eggs 82. *hese fish ranged in length from 554- to 682-mm.

Eggs hatch after four or more months under natural conditions, usuelly between mid-Tebruary and the end of M: t;h'88o> . Newly hatched las/ae are approximately 14-mm in length'88o'. They spend about one month among the Amendment 3 '. 2-163 June 1979 o%

Their growth rate varies over their geographic range but is generally fairly rapid. An average growth of 2.8 mm/ week was reported for young-of-the year in Lake Superior between late June and late October, with first year growth ranging from 64- to 100-mm in Lake Superior and from 87- to 125-mm in Lake Michigan'828,88. Average lengths of lake trout for a nunber of northern lakes ranged from 99- to 267-mm for age II, 315- to 511-mm for age V, 354- to 643-mm for age IX and 412- to 709-em for age XII fish. The average lengths of various strains of lake trout planted in Lake Ontario since 1972 were 342- to 407-mm for age II, 471- to 534-mm for age III, 550- to 560-mm for age IV and 618-mm for age V fish'8298 These lengths indicated variations in growth rate between the three stocked strains with overall exceptional growth during the past 5 years in comparison to growth rates reported for other copulations of lake trout in northern lakes.

Sexual maturity is usually reached at age VI or VII (or at about 600-mm in length), with males maturing before femalest''. Variations in age of maturity were observed between different strains of lake trout stocked in Lake Ontario'82. Maturity was reached as early as age III for 4.3 to 32.4 percent of males and at age IV for 7.7 to 12.5 percent of females. Over 98 percent of males and 84 percent of females were mature at age V. These results indicated relatively early maturity, and the initial stock is expected to spawn several times cefore disappearing frc= the population.

Lake trout are long lived and grow to a large size; the oldest recorded age is 37 years and the largest size on record is 49.5-in (12,600-mm) and 102 pounds lf (46,300 g)'8'o'. Although rate of growth in length decreases among large lake trout, the rate of increase in weight rises markedly. This trend was illustrated by the average lengths and " eights listed by Eschmeyer'828' for Lake Superior lake trout, which shoved increasingly greater proportional growth in weight than in length after they had reached 300-mm in length. Lake trout collected during 1977 Mexico Bay sampling did not exhibit any :onsistent relationship between length groups and K-factors (Table 2.2-220). Mean K-factors ranged from 0.96 to 1.34 for various size groups of lake trout collected during June, July, and October, and no trends were apparent between mu.ths or between nales and females. Mean K-facto;s calculated for lake trout cu'lected during NJ5DEC Lake Ontario sampling'82 increased steadily with age from 0.99 to 1.00 for age II, 1.09 to 1.10 for age IV, and 1.12 for age V.

Densities on 2 May decreased as distance from shore increased, whereas during the week of S May the trend was rcversed (Figure 2.2-102). The only vertical distribution pattern observed occurred during the week of 9 May when densities were generally greater on the surface than near the bottom (Figure 2.2-103).

Yellow perch postlarvae were collected from 2 May through 27 June (Figure 2.2-79), with a peak mean density of 1.3/100 cu m during the week of 9 May (Appendix Tables 2.2E-34 and 2.2E-35). On all dates, day samples contained fewer larvae than night samples. Transect III had higher densities of postlarvae during the vaak of 9 May than either of the other two transects (Figure 2.2-101). Pcstlarvae had a depth distribution similar to that described for prolarvae during the week of 9 May; that is, as depth and distance offshore increased, densities also increased (Figure 2.2-102).

Vertical distribution trends were not apparent (Figure 2.2-103).

Yellow perch young-of-the year were collected on 18 July (Figure 2.2-79, Appendix Table 2.2E-36), but low densities precluded distribution comparisons.

Yellow perch have been common in ichthyoplankton collections throughout eastern Lake Ontario and have been dominant (in terms of abundance or density) during various periods. Yellow perch were collected in Mexico Bay and at other sites2', 8o from late April through late May or early June (Table 2.2-255). During day sampling, the study at the Nine Mile Point-l FitzPatrick site recorded mean densities for the study area similar, although not directly comparable, to night samples from the present study. The Sterling site studies also recorded mean densities for the study area of the same order of magnitude, indicating there was no appreciable difference in abundance of yellow perch larvac among the three sites.

Seventeen additional taxa were collected in the study area (Figure 2.2-79).

The low densities of these taxa may in part reflect their reproductive life histories and the efficiency of sampling gear (Table 2.2-254). Many of these taxa have demersal and adhesive eggs. The Hensen nets used in the present l

study are most effective for collecting planktonic or semibouyant life stages.

The majority of fish taxa resident in Mexico Bay spawn in shallow areas or in tributaries. Consequently, the most productive spawning areas were of ten those least accessible for sampling. Life stages of several taxa may not have been collected because the adult male protects the young.

Eight taxa (Cyprinidae, carp, emerald shiner, spottail shiner, trout-perch, threespine stickleback, Lecomis spp., and Cottus spp.) "ere collected in d4y and night samples at densities higher than 1/100 cu m (Appendix Tables 2.2E-37 and 2.2E-38). Each of the life stages for these taxa were collected sporadically precluding interpretation of their distribution.

NYSE8G ER NEW HAVEN-NUCLEAR estimates of species composition and relative abundance during this period are possible by extrapolation from three data bases:

1. Data collected in Mexico Bay from April through December 1977.

2. Data collected during entrainment/ viability studies at James A.

Pit: Patrick Nuclear Power Station from January through December 19772

3. Data collected in the vicinity of the Nine Mile Point Nuclear Power Station from April through December 1977*

Salmonidae was the only fish family collected (Section 2.2.2.1.6.4) in the study area which contained fall spawners. Burbot (Gadidae) was the only winter spaening species present in the area. There is no indication that the Mexico Bay study area is a spawning area for species of salmonids; these fall spawning species normally return to the areas in which they were stocked to spawn. The closest known stocking location f or salmonids is the Salmon River Estuary, approximately six miles northeast of the study area. Therefore, eggs and larvae from salmonid species would not be expected to occur in the study area.

Spring ichthyoplankton collections in Mexico Bay, starting in April, produced early life stages of burbot and lake herring (Section 2.2.2.1.7). Burbot prolarvae and postlarvae and lake herring postlarvae were the first specimens te appear in the 1977 collections. 3urbot and lake herring prolarvae and postlarvae were also collected during sampling in Apri' and May in the vicinity of Nine Mile Point'56. Densities of these life stages were similar for the Mexico Bay and Nine Mile Point study areas. Burbot eggs and larvae were also collected in February and May during entrainment sampling at the James A. Pit: Patrick Power Station2. No new species were collected at the Pit: Patrick Station from January through March 1977. It is therefore probable that only eggs and early life stages of burbot and lake herring would be present in Mexico Bay from January through March.

2.2.2.1.7.6 Statistical Treatment of Data Statistical analyses using parametric analysis of variance (ANOVA) and Tukey's multiple comparison procedure were performed on mean density data (no./100 cu m) of each ichthyoplankton taxon life stage for which sufficient data were available Data which included zero catches at approximately 50 percent or more of the sampling locations was considered insufficiant for statistical analysis of spatial distribution. Tests were performed to determine significant differences (P50.05) in mean densities between depth contours, transects, levels within the water column, and time of day. Mean surface densities were tested for differences between all depth contours, and separate tests were conducted to compare mean densities between the 20 , 30 , 40 , and 50-ft depth contours, with surface, middepth and bottom densities combined. Comparisons of levels in the water column were performed on mean densities at the 20-Amendment 3 2. -190 4

NYSE8G ER NEW HAVEN-NUCLEAR through 50-ft contours, a r. day and night densities were compared for locations on Transect II_. Separate tests were conducted for each sampling date when sufficient data were available. Significant interaction between main effects was prevalent in many of the tests; and when interaction occurred, Tukey's multiple comparison procedure was used to test for signi-ficant differences between mean densities at individual sampling locations or levels. An extensive number of analyses were performed, however, statistical results are presented only for tests which revealed significant patterns of distribution. Where no significant differences were detected or where trends were inconsistent, results are briefly described. Results are discussed by life stage and taxon in phylogenetic order.

Alewife Sufficient data for statistical comparisons of alewife egg densities were available only for 18 July. Comparisons between transects, depth contours, and icvels indicated that egg densities were not significantly different between levels but were significantly less abundant as depth increased and along Transect I (Table 2.2-256).

Sufficient data for statistical analysis of alewife prolarval densities were also available only for 18 July. Comparisons between transects, depth contours, and levels all yielded significant differences (Table 2.2-257).

Surface densities were significantly greater at Transect I than at Transects III and V, and were significantly greater at Transect III than at Transect 7.

They were also significantly greater at the 20-ft depth contour than at other contours. Prolarvae were significantly more abundant at all levels at the 20-ft depth contour. Significant differences between levels in the water column occurred only at Transect I where surf ace densities - e significantly greater that bottom densities at all but the 50-ft depth _ontour. No significant differences were noted between day and night densities at any depth contour or level.

Alevife postlarvae were abundant during much of the summer, and statistical comparisons were conducted on weekly data fren 27 June through the week of 5 September (Tables 2.2-258 through 2.2-260). The many significant differences were ncted, and distributional trends varied among sampling dates.

On the first three weeks for which tests were performed (27 June, 4 July, and 11 July) densities were relatively low, and patterns of significant differences varied. Significant differences in mean densities at all water column levels combined and at the surface level on 27 June indicated that Amendment 3 2.2-190a of June 1979 565067

NYSEAG ER NEW HAVEN-NUCLEAR 2.4.1.2 Onsite Streams 2.4.1.2.1 Introduction The water quality of two onsite streams, Catfish and Butterfly Creeks, was characterized by monitoring general water quality parameters, nutrients, and indicators of contamination from April 1977 through March 1978. Samples were not collected if streams were not ficwing or covered by ice. A complete set of data collected for the study is presented in Appendix 2.4A. Summary data are presented in Tables 2.4-14 and 2.4-15. Monthly means for each parameter are presented in Table 2.4-16.

2.4.1.2.2 Catfish Creek The water quality survey of Catfish Creek and its eastern tributaries involved five sampling locations. A complete description of the locations sampled is presented in Section 6.2.

No published historiczl data for Catfish Creek or its tributaries are available for cumparison to data from the present study. New York State Department of Environmental Conservation 1977, has designated Catfish Creek and the tributaries as Class C vater and Class D, respectively. The Water Quality Standards are presented in Appendix 2.4A.

2.4.1.2.2.1 Overview of Physical and Water Quality Parameters General Water Quality Parameters Current Velocity Data recorded at sampling Location 510 (Figure 2.4-63 or Figure 6.1-5) is

[

presented in Table 2.4-24 Location 10 is located near the mouth of the creek I and thus the measured velocities and flows are based on the contribution from essentially the entire drainage basin. Current velocity ranges from a minimum of 0.02 m/sec during June, July, and September to a maximum of 0.46 m/sec during May. Months with greater precipitation (April, May, October and November) exhibit higher velocities than months with lesser precipitation rates (June, July, August, and September). The average velocity for the sampling period is 0.07 m/sec.

S* ream Flev Stream flow (Table 2.4-24) at Location 510 ranges from a minimum of 0.23 cu m/sec during June to a maximum of 6.0 cu m/see during November. Flow rates decrease from the spring months (April and May), reach a low-flow summer period (June, July, and August), and increase in the fall (October and November). The average flow rate for the sampling period is 1.52 cu m/sec.

As stated in Section 2.3.3.2.1, total precipitation during April 1, 1977 through March 31, 1978 was considerably higher than the climatological norm.

DrainaRe Area The area above the N.Y. Central Railroad which is drained by the creek is 36.1 sq mi, and 36.8 sq mi are drained in all. The Catfish Creek basin contains 8.64 sq mi of swamp / marsh. The drainage is shown in Figure 2.4-63.

Gradient The average gradient above the railroad is 4.3 ft/mi from 10 percent upstream to 85 percent upstream.

Iemoerature The temperature of Catfish Creek ranged from 0.0'C to 25.5'c with a mean of II.8'C. Temperature was not measured during periods of low water volume and ice cover. Upstream temperatures were usually lower than downstream temperatures. The greatest temperature difference (6*C) occurred on June 27 however, the difference between the temperature upstream and downstream was usually 2' to 3*C. Weekly in situ temperature measurements revealed normal seasonal variations. The lowest monthly mean (0.0'C) was recorded in January while the highest monthly mean (20.8'C) was recorded in July (Table 2.4-16).

Dissolved Oxygen and oxy 2en Saturation Dissolved oxygen (DO) concentrations ranged from 4.5 to 14.3 mg/l with a mean of 8.8 mg/1. Oxygen saturation ranged from 33 to 117 percent with a mean of 80 percent. Do concentrations showed a negative correlation to temperature and followed normal seasonal patterns.

Dissolved oxygen concentrations were always above the New York State standard for Class C water (trout waters, 5 mg/l oxygen; and non-trout waters 4 mg/l oxygen) for locations on Catfish Creek. The reach of Catfish Creek from Location 1 to S10 is classified as trout waters. The lowest DO recorded at Location 1 was 6.2 mg/l on August 1. The remainder of Ic ations on the tributaries (Locations 2, 3, and Sil) are classified as Class D vaters.

Dissolved oxygen concentrations never fell below the standard of 3 mg/l at these locations. Oxygen saturation in Catfish Creek ranged from 33 to 117 percent, with a mean of 80 percent. Throughout the year lowest oxygen saturations were present at upstream Locations 3 and Sil. These lov saturations were probabl> related to low stream flow, particultrly during the summer months.

Eh The pH in Catfish Creek ranged from 5.7 to 8.9, with a mean of 7.1. The pH values recorded at downstream locations were generally higher than pH values at upstream locations. The pH at Location 1 , occasionally reflected the inflow 56569e m e Amendment 3 2.4-32 June 1979

NYSERG ER NEW HAVEN-NUCLEAR Stream Flow Stream flow (Table 2.4-25) at Location 9 ranges from a minimum of 0.0036 cu m/sec during September to a maximum of 1.9 cu m/sec during October. Flow rates decrease from the spring (April and May), reach low-flow state in summer (June, July, August, and September) and increase in the fall (October, November, and December). The average flow rate for the sampling period is 0.35 cu m/sec.

As stated in Section 2.3.3.2.1, total precipitation during April 1, 1977 through March 31, 1978 was considerably higher than the climatological norm.

Therefore, the flows measured during 1977 may be somewhat higher than one would expect on a long term basis.

DrainaRe Area The drainage area of Butterfly Creek as shown in Figure 2.4-63 is 8.9 sq mi.

About 6.3 sq mi are drained above the mouth of Tributary B,which is a little below the site boundary. The basin contains 0.47 sq mi of swamp / marsh.

Gradient Considering that portion of Butterfly Creek above the mouth of Tributary B, the average gradient is 16.4 ft/mi from 10 percent upstream to 85 percent upstream.

NYSERG ER NEW HAVEN-NUCLEAR The field investigation located 14 archaeological sites within the limits of construction. A group of six of these sites (Site numbers 1, 2 , 4, 5, and 6 in the northwest quadrant and Site number 14 in the southwest quadrant of the construction area) consist of modern (less than 50 years old) refuse dumps. These sites can be dismissed since they are too recent and without sufficient cultural importance to meet the criteria for nomination to the National Register of Historic Places and are of limited archaeological significance. The remaining eight sites have potential archaeological significance. Two sites (Site numbers 3 and 12) are located within the northwest quadrant. Site number 3 consists of a 19- early 20th century barn foundation and covers an area 58 x 132 ft. Site number 12 is the Rome-Oswego Railroad, completed through New Haven in 1865. The line later became part of the Rome, Watertown, and Oswego Railroad and, still later, part of the New York Central system. The rail line was abandoned in 1959. Two sites (Site numbers 10 and 13) are located within the northeast quadrant of the limits of construction. Site number 10, foundations of a 19th century farm, covers an area 200 x 20C ft and includes a barn, toolshed, ice house, milkshed, and house. A modern dump lies just behind the house and covers an area approximately 200 ft in diameter, including parts of the habitation site. Site number 13 consists of a small refuse scatter covering an area 30 x 37 ft. The material seems to date to the early 20th century. The southeast quadrant contains two sites - Site numbers 7 and 11. Site number 7 covers an area approximately 40 x 30 ft and consists of a scatter of refuse and large stones which suggest the presence of a 19th century house foundation. Site number 11 consists of a house foundation, wells, and refuse area which has dated to the late 19- early 20th century. The site covers an area 200 x 150 ft. Two sites (Site numbers 8 and 9) fall within the southwest quadrant. Site number 8, a barn and silo foundation, covers an area approximately 70 x 60 ft. Both were built in the late 19th century. Site number 9 consists of the foundations of a late 19- early 20th century farm complex. Included in the complex are a house, granary, ice house, milkshed, and barn. A fieldstone obelisk found on the site is of undetermined age and significance and was partially destroyed during the 1977 hunting season. 2.6.3 Resources within 5 Miles No structures listed on either the National Registry of National Landmarks are located within 5 mi of the site. The nearest property listed as eligible for l the National Registet of Historic Places is the Gustin-Earle Factory located in a 19th century industrial area, along the Little Salmon River in the Village of Mexico. This factory, located approximately 2 mi east of the site, manufactured butter dishes, animal polks, pails, and caskets in the 1870's. This site was excavated prior to construction of a sewage treatment plant and is probably no longer eligible for the National Register. Amendment 3 2.6-3 6IJune 1979 ()'d'/

NYSE8G ER NEW HAVEN-NUCLEAR One building 9hich is included in the state inventory of historic places, at the recommendation of the St. Lawrence-Eastern Ontario Commission, is the Shepherd-Timbello House in the Town of New Haven. Located on the northeast corner of State Route 104 and County Route 6, the house is a large rambling structure with an observation tower built in the latter half of the nineteenth century. It is, however, in a dilapidated condition. At the death of the last Shepherd family owner, the building was sold to a local philanthropist while most of the surrounding property was given to the State University Foundation Inc. After che closing of a special school housed in the structure, the interior furnishings of the building were sold at auction and the house itself is now for sale. Visitors to the location are negligible'2'. Upon request, town historians identified a few other places of local historical interest including three churches in the Town of Scriba, the grave site of Silas Towre (a revolutionary var spy for George Washington) at Mexico Foint, and several residences in the Village of Mexico. All of these places are of uncertain historic value and all vould be between 4 and 5 mi from the proposed station. A formal opinion regarding the present condition of, and potential station impacts on, these and other historic places near the site has been requested from the New York State Division of Historic Preservation. A reply from Mr. Frederick L. Rath, Deputy Commissioner of the New York State Department of Parks and Recreation, is expected. 2.6.4 'li s u a llY Sensitive and Intensive land USes - Inventory Visually sensitive and intensive land use areas within a 5-mi radius of the proposed station site are presented in Figure 2.6-1. These areas, include residential concentrations, recreational and conservation areas, historic sites and scenic areas as well as highways and roadways or rail lines through the area. The significant visually sensitive or intensive locations that exist in the area involve permanent and seasonal residences and recreational usage along Lake Ontario. There are no historic sites, national parks, or major publi.c recreational areas and no major highway or rail corridors within 5 mi of the site. Selkirk Shores State Fark is the chief recreational attraction in the area, although it is beyond the 5-mi radius from the station. Other potential visually sensitive locations within 5 mi, such as Derby Hill bird refuge, Noyes Woods bird refuge and forest preserve, and Butterfly Swamp wetlands do not have views to the site. The representative photo locations chosen are described below. A limited number of photo locations were identified because of the low residential concentrations and limited number of public facilities within 5 mi. Selected photo locations from representative visually sensitive and intensive areas are also shown in Figure 2.6-1. These photo locations were selected to portray the views generally afforded of the station from various locations within a 5-mi radius. 56E 4 Amendment 3 = 2.6-4 June 1979

Figures 3.1-2 and 3.1-3 show the proposed finished contours and vegetative cover following construction and restoration of the site. Figure 3.1-3A shows offsite restoration in the makeup / blowdown pipeline corridor. Figures 2.1-2 and 3.1-4 show the locations of release points for liquid and gaseous vastes, and Figure 3.1-5 shows the elevations of gaseous release points. Figure 3.1-6 shows site elevation views rendered from a southeastern and southwestern direction. Figures 3.1-7 through 3.1-10 show elevation views of proposed architectural facade details. Figures 3.1-11 through 3.1-13 show architectural perspectives of the station and site area. Figure 3.1-14 presents an aerial photograph of the site area taken during a defoliate season. Figure 3.1-15 shows those site areas where major structures and excavation will be necessary during the construction of the facility. The major station structures are located in the southwest quadrant of the site. The proposed locations of these structures were determined by several factors: Nuclear Regulatory Commission requirements, railroad access, transmission exit from the site, and minimum topographic change. A specific objective in station location was to have Butterfly Creek remain essentially undisturbed both during construction and station operation. A natural vegetative buffer zone, large enough to avoid any sedimentation from adjacent cleared land entering the stream, will be left intact betweer. the creek and any construction activity. The station layout also minimizes irpact on the mature grove of trees located on the western portion of the site. The major materials for station structures are concrete and metal. The reactor containment structures, annulus buildings, diesel generator buildings, service water cooling towers, diesel generator fuel oil pumphouses, heating, ventilation, and air conditioning (HVAC) buildings, and etntrol buildings are built primarily of concrete. Other concrete structures include the natural draft cooling towers and pumphouse, and fuel buildings. The concrete is cast in placej Its exposed surfaces will be untextured, and its color is that of natural concrete. "he so{id waste and decontamination buildings above grade, service building, normal switchgear buildings, administration building, makeup water pumphousa, turbine buildings, and warehcase are primarily metal clad. Transmission towers and switchyard equipment are primarily metal frame structures. Heignt and spacing of switchyard structures and equipment are based on the National Electric Safety Code and Northeast Power Coordinating Council design criteria and assumed equipment parameters are given in Tables 3.1-1 and 3.1-2.

Uniforn surface color treatment of metal clad structures is used, where appropriate, to enhar.ce station unity. In buildings where natural lights and views are beneficial, such as the administration buildings, windows are installed. Tanks above ground are finish painted in colors that are compatible with the surrounding station structures. Permanent station roads and parking areas are paved surfaces of untextured asphalt. Lane markings are painted in either yellow or white. The site is landscaped to harmonize with the structures and natural topcgraphy. During the excavation phase of construction, existing natural features are preserved where possible. The proposed revegetation, including ground cover and upright vegetation, is based on existing surrounding vegetation materials to re-establish the color, texture, and species composition prevalent in the area. Existing vegetation, with crown heights above the proposed station finish grade, that is preserved durirg construction will restrict site views of the lower station elements along the site boundary. The most effective visual screen is located parallel to State Route 104 This screening consists of landforms built up to elevations above the station finish grade and planted with screen plantings. 'a'here a high density visual buf f er is app ropriate, as in the case of nearby residences which face directly onto the site, evergreen trees are massed. I'here the need f or screening is less immediate, wider bands of deciduous and evergreen vegetation are planted. Both species composition and spatial arrangement are directed towards reflecting the character of this region. Areas not planted with trees or shrubs are seeded to control ere. ion. Ground cover for yard areas consists of lawn or crushed stone (Figure 3.1-3). Section a.5.3 provides a discussion of the landscape restoration to be performed during station construction.

NYSE10 ER NEW HAVEN-NUCLEAR 3.6 CHEMICAL AND BIOCIDE WASTE SYSTEMS 3.6.1 Water Treatment Systems 3.6.1.1 Rav Water Makeuo System Water is taken directly from Lake Ontario at a constant rate of approximately 36,400 spm. The combined two-unit circulating water system cooling towers and ultimate heat sink require 35,520 gpm and 800 gpm, respectively to replace blevdown, evaporation, and drift losses. Approximately 450 gpm are conveyed to the demineralized water makeup system when demineraliz.ed water makeup is required. The pH of the makeup water to the natural draft cooling towers (circulating water system) is reduced to approximately 7.7 to control calciun carbonate scaling by shifting the carbonate / bicarbonate equilibrium. This is accomplished by adding an average of 27,800 lb of 93 percent H 2 SO, per day to the makeup water before it is introduced into the circulating water system. Rav vater quality and cooling tower blevdown vill be monitored periodically for pH, alkalinity, and calcium, for the purpose of controlling the calcium carbonate saturation index of the circulating water. No spacific procedures have been prepared for makeup water pH sampling and monitoring. 3.6.1.2 Demineralized Water Makeup System The demineralized water makeup system is located in the service building (building 13 of Figure 3.1-1). The demineralized water makeup system, by treatment of Lake Ontario water, provides high quality filtered and domineralized water for use in the condensate cycle and for other station uses. The system is comprised of:

1. A pretreatment process, including a rav vater tank and two activated carbon filters.

2. A demineralizer process, including two cation, two anion, and two mixed-bed ion exchange units arranged in two parallel trains.

Figures 3.6-1 and 3.6-2, respectively, are schematic diagrams of the pretreatment process and the demineralizer process. During normal station operation, a carbon filter and one demineralizer train is in service, with a ca bon filter and a second demineralizer train on standby or undergoing reconditioning. During peak demand periods all units can be operated simultaneously, at the design system flow rate of 450 gra of demineralized water to the demineralized water storage tank. Pretreatment Process The rav vater is taken from Lake Ontario and directed to a 2,000 gal rav vater tank. The water is then pumped at a design flow of 225 gpm through each of two activated carbon filters to remove suspended solids and dissolved organic t Amendment 3 . 3.6-1 [$(5Eh3EN P June 1979

NYSEEG ER NEW HAVEN-NUCLEAR compounds. The pretreated makeup water is then directed to the demineralizer process for further treatment. When a demineralizer train is chemically regenerated (see below), the activated carbon filter serving that train is backwashed with raw water. The frequency of this operation is described in the following subsection. Approximately 3,600 gal of wastewater are produced from the backwash of an activated carbon filter. This vastewater is combined with the regeneration vaste in the vaste neutralizing tank. The total suspended solids concentrations (TSS) provided in Table 3.6-2 are those promulgated in 40CFR423 for low volume vastes. These allowable concentrations reflect, and are slightly higher than, the theoretical TSS concentrations obtained by dividing the total mass of suspended material removed from the raw water during the filter run, by the combined wastewater volume of the activated carbon filter backwash, and associated anion and cation demineralizer train chemical regenerant volume.

   ?cminaralization Process The deminerali:ation process is divided into two trains.               Each train, consisting cf a cation, an anion, and a mixed bed demineralizer, has the capacity to produce 225 gpm of domineralized water.

Essentially all dissolved constituents present in the water are removed by the cation and anion demineralizers. The mixed bed demineralizers serve as polishing units to remove trace quantities of dissolved solids which may pass through the cation and anion demineralizer units. After demineralized water passes through the mixed bed demineralizer units, it is stored in the demineralized water storage tank for subsequent use in the station. The volumes of the decineralizer beds and the demineralized water storage tanks are: cation bed (2) 215 cu ft resin / bed Anton bed (2) 172 cu ft resin / bed Mixed ted (2) 60 cu ft resin / bed Dcmineralized water storage tanks (3) 450,000 gal / tank Resin bed volumes are based on a service run length of 20 hr at the rated capacity, and assuming a design raw water quality based on the monthly ambient water sample having the maximum total dissolved solids concentration (Refer to appendix 2.aA, Table 2.4A-1, June 1977 data) adjusted for ion balance. Demineralized water storage tanks are designed to fulfill steam and power conversion system peak water requirements during station startup. Makeup demineralizer system product water quality is as follows: Amendment 3 3.6-2 M tj[geggg gg June 1979 i

The regeneration vastes flow to a vaste neutralization system for pH adjustment to between 6.0 and 9.0. The cation and anion exchange units are designed to be regenerated once every 20 hr during maximum conditions. It is estimated that based on average deminerali:ed water demand each train will be regenerated approximately once every 10 days. During regeneration, each unit is first backwashed with normal influent vater. The cation resins are chemically regenerated with 2 percent, 4 percent, and 6 percent solutions of sulfuric acid. The anion resins are regenerated with a 4 percent solution of sodium hydroxide. Each anicn unit is rinsed with demineralized water to a low conductivity end point. Each cation unit is rinsed with filtered water. A similar procedure is used to regenerate the mixed bed units. Regeneration of the mixed bed units is estimated to occur once every 60 days. The approximate average quantities of chemicals expected to be used pec month are as follows: Sulfuric acid 6,500 lb as 93% H 2 S0y Sodium hydroxide 10,000 lb as 50% NaOH The volume of the chemical regeneration vaste for a single demineralizer train is approximately 27,000 gal. Regeneration of the mixed bed demineralizer associated with the train results in approximately 2,700 gal of wastewater, included in the 27,000 gal total volume. The regeneration vaste volume is not affected by run length time (i.e. frequency of regeneration). The vaste neutralization system includes a 50,000 gal neutralization tank which has 1.85 times the capacity required for the neutralization volume of one complete demineralizer train. The neutralization tank is provided with pumps, pH instrumentation, and mixing equipment. The mixer will provide for uniform characteristics of the tank contents to facilitate thL batch neutralization process; the mixer will operate during discharge of the neutralized waste to ensure uniform discharge characteristics. The vaste neutralization system pro-vides for continuous pH monitoring of the tank contents during neutralization and subsequent discharge. A grab sample of the discharge from each neutralized waste batch is analyzed for total suspended solids. Figure 3.6-3 shows the system, and Section 3.6.7 gives the anticipated composition and flow of neutralized wastes discharged. 3.6.2 Biocide system Biofouling in the cooling water system is centro 11ed by chlorination using sodium hypochlorite, which is generated onsite as needed. Hypochlorite solution is injected into the circulating water and service water systems. I e a 6 . ne 1979 565'r'--3

NYSE8G ER NEW HAVEN-NUCLEAR The circulating water and the turbine and reactor plant service water systems for each unit are dosed at various times. In the circulating vater system, the injection points are just upstream of the inlet water box in each condenser train. In the turbine plant service water system, the hypochlorite solution is injected into the main pipeline upstream of the heat exchangers. In a similar manner, the reactor plant service water system is dosed into the line supplying the reactor plant heat exchangers at a point downstream of the reactor plant cooling tower blowdown takeoff point. Hypochlorite addition to the circulating water system is controlled by chlorine analyzers. Each stream that is chlorinated has an automatic free available chlorine analyzer / controller located downstream of the last waterbox. Hypochlorite addition is controlled to maintain a free available chlorine level of 0.5 ppm at the analyzer during chlorination. Automatic feedback control is performed by free chlorine analy7ers. The circulating water system and both service water systems are chlorinated twice per day for a period of 30 minutes each time. Based on the above chlorination characteristics and the EPA residual chlorine model( , calculatiens indicate that both free available and total residual ct.lorine concentrations should comply with applicable federal effluent regui2tions indicated in -CCFR423. Figure ?.6

shows the points of injection and locations of free residual chlorine analyzers.

The sodium hypochicrite biocide system includes sodium hypochlorite generators, a sodium hypochlorite solution storage tank, a sodium chloride dissolving storage tank, hypochlorite feed pumps and distribution equipment with associated controls, and residual chlorine monitoring systems. 3.6.3 Floor and Equirnant Drainsee Nonradioactive plant ficor drainage and runoff frem the auxiliary boiler fuel oil storage area which may contain suspended solids, oil or grease is routed through oil-water separators before it is discharged to the cooling tower bicudown.

Transformers and reactcvs are placed in concrete basins. A separate, underground drainage system conveys runoff which originates on the surfaces of the transformers and reactors, as well as any potential oil spillage, to collection pits constructed of concrete. The collection pits are designed to contain as a minimum, the entire cil contents of the single, largest trans# emer in an area, in addition to the runoff from the once in 10 yr, 24 hr storm defined previously in this section. The

1argest oil volure from a single transformer in the station transformer areas is approximately 36,000 gal. The oil volume of the single largest transformer in the area of the switchyards is approximately 18,500 gal. The collected storm water runoff from the transformers and reactors is treated in a corrugated plate type oil / water separator and discharged to storm drainage.

 "ost oil spillage is cleaned up manually; any remaining oil removed from the oll/ water separators, and any manually cleaned spillage would be disposed of offsite by a licensed contractor.

Monitoring of the performance of switchyard and station transformer equipment, routine ensite inspection of electrical equipment, manual cleanup of any leakage cr spills associated with equipment maintenance, and the design of the drainage and treatnent system for the station transformer and switchyard areas are expected to minimize, if not preclude, any oil discharges to storm drainage. Weekly composite samples from the effluent of the oil / water separators will be analyzed for oil and grease.

NYSEtG ER NEW HAVEN-NUCLEAR 3.6.7 Discharges to Water 3.6.7.1 Cooline Tower Blowdown The evaporation of water is the main heat transfer mechanism and results in an increase of the dissolved solids concentration in the circulating water. To control the dissolved solids level in the circulating water, a portion of the circulating water is withdrawn as blowdown. The cooling tower blowdown rate varies, such that under normal operating conditions, the makeup to blowdown flow ratio results in an average concentration factor of dissolved solids of approximately 3.0. As the cooling tower evaporation varies during the year, the resulting concentration factor varies from a maximum of 6.0 to a minimum of 2.45. It is estimated that the maximum instantaneous concentration factor (as measured by mass balance of makeup flow and evaporative losses deterrined from hourly meteorological observations) during the data period will be equalled or exceeded for 3 hr in 10 years, based on 10 years of meteorological data from Syracuse Hancock International Airport (National Weather Service). Table 3.6-1 lists the estimated average and maximum chemical concentrations in the cooling tower blowdown. The average concentration is based on the average concentration factor and average ambient concentration of each parameter. The annual average and maximum ambient water quality is summarized in Table 3.6-6. The maximum composition represents the estimated worst possible conditions for that particular parameter while the average composition represents the expected normal operating condition. Both the average and the maximum concentrations for iron, chromium, and nickel include the increase in the concentrations of these metals due to corrosion in the circulating water system and the turbine plant and reactor plant service water systems. Cooling tower blowdown complies with 40CTR423. 3.6.7.2 Neutralized Demineralizer vastes Neutralization is performed on a batch basis. The neutralized wastes are released at : rate of approximately 100 gpm to the co' ling tower blevdown system.

1. Carbon filter backwash and rinse

2. A cation and anion regeneration cycle

3. A cation, anion, and mixed bed regeneration cycle The mean concentration is bat on the design regeneration cycle and the maximum concentration of each parameter, except for the trace elements which are based on average ambient concentrations.

A brief description of the reasons for their use is included in the table. The table gives estimates of monthly station use, station discharge, and the frequency of use. Table 3.6-4 shows the chemicals used for initial plant startup. The quantities of sulfuric acid and sodium hydroxide indicated in Table 3.6-4 represent the total requirement for chemically regenerating the ion exchange demineralizers for the makeup demineralizer and the condensate polishing demineralizer systems during initial startup. Of these total quantities, 15 percer.t are discharged from the neutralized makeuc demineralizer regeneration vaste. The composition of the neutralized waste is indicated in Table 3.6-2. The remaining acid and caustic quantities, as well as all otber chemicals indicated in Table 3.6-4, are not discharged,but are either used in closed systems or evaporated as described in Section 3.5-2. Freoperational cleaning is described in Section 4.1.11. 3.6.7.4 Cembined Waste Discharge Cooling tower clowdown is released continuously to Lake Ontario during station operation and serves as dilution water for the release of other treated liquid wastes. The estimated average and maximum chemical concentrations of the combined waste discharge is shown in Table 3.6-5.

NYSE8G En NEW HAVEN-NUCLEAR 3.7 SANITARY AND OTHER WASTE SYSTEMS Sanitary waste water is treated in a package sewage treatment plant. During station operation, the effluent is discharged to Lake Ontario via the cooling tower blowdown line. The sanitary waste treatment system is designed to treat the maximum flow of sewage (i.e. 90,000 gpd) which occurs during construction of the station (Section 4.1.5), as well as the sewage flows occurring during station operation. The expected station population during normal operation is 191; during refueling the station population increases to an expected maximum of 541. Based on rates of 35 gal per capita per day of sanitary waste water and 0.085 lb of 5-day biochemical oxygen demand (BODS) per capita per day, the maximum daily quantity of sanitary waste water during refueling is approximately 18,900 gal which contains 46 lb of BODi. The average daily sanitary easte water flow is 6,700 gal which contains 16.3 lb of BODS. Table 3.7-1 summarizes the characteristics of sanitary waste prior to treatment. As a minimum, the sewage treatment plant provides the following effluent quality as required by 4CCTR133 and Neu York State Environmental Conservation Law 17-0509 for secondary treatment: Parameter Effluent Ouality BODi 30 mg/l for 30 consecutive day average 45 mg/l for 7 consecutive day average Total Suspended 30 mg/l for 30 consecutive day average Solids (TSS) 45 mg/l for 7 consecutive day average pH 6.0-9.0 pH units The sewage treatment plant also satisfies the requirement to remove 85 percent of TSS arid BODS. A schematic flow diagram of the sanitary waste treatment system is presented in rigure 3.7-1. The sewage treatment plant system uses the rotating biological contactor process. This process is a secondary biological treatment system consisting of a number of closely spaced discs mounted on a horizoatal shaft. The discs are slowly rotated while partially submerged in vaste water so that the biological growth on the discs is alternately submerged and aerated. Organic material in the vaste viter is oxidized by the growth of micro-organisms on the disc surfaces or synthesized into additional biological solids. Excess biological solids are sloughed off by the shearing force caused by disc rotation. Sloughed solids are separated from the t-eated waste water in a clarifier. Waste biological solids are discharged to an aerated sludge holding tank, which providet a storage capacity of 40 days for the maximum accumulation of sludge during station refueling. The sludge holding tank provides aerobic 3.7-1 r r-3 iD
NYSE8G ER NEW HAVEN-NUCLEAR digestion for the vaste biological solids. Based on inspection of the accumulated sludge volume in the tank, sludge is settled and then pumped from the tank for aisposal to an approved offsite location by a DEC licensed contractor. Sludge volume during normal station operation is estimated to be 1,800 gal per month based on an assumed 2 percent solids concentration. Effluent from the sewage treatment plant is chlorinated prior to discharge to the cooling tower blowdown. The sewage treatment plant effluent complies with the following DEC guidelines (Policies and Procedures Manual, Title 9:00, Chapter 9: 10) for fecal coliform bacteria: 200 MFN*/100 mi for 30 consecutive day geometric mean 400 MpN*/100 m1 for 7 consecutive day geometric mean
~~Maximum Probable Number Table 3.7-2 provides a summary of effluent quality and quantity.~~
Table 3.7-3 lists the sizes of the two equalization basins, the rotating biologreal cont actor (R3C), the two clarifiers, and the disinfection chamber. During construction, both equalization basins and clarifiers are used. The larger of the two equalization basins and the two clarifiers are disconnected for the relatively lower loadings which occur during station operation. RBC sizes are tased on typical ecuipment manufacturer's information. The clarifier and disinfection chamber capacities are designed in accordance with the appropriate surface settling rates and detention times indicated in the " Ten-State Standards". Equalization basins are designed to contain approximately two-thirds of the peak daily sewage flows during station construction and during station operation. Effluent from the sanitary waste treatment system will be monitored as set forth by the 40: State Discharge Fermit. The station produces general refuse, which typically includes paper, metals, food waste, yard rubbish, synthetics, rags, and inerts such as glass, stone, dirt, and screen washings from the intake system. Paper is the principal ccmponent of this refuse. About once a week, general refuse is hauled from the statron by a state licensed contractor to an offsite DEC approved sanitary landfill. B_aferance

NYSE8G ER NEW HAVEN-NUCLEAR During the first 2 years of construction, potable water will be obtained from an onsite well. A temporary treatment system is used to produce 50 gpm, net, of potable water in compliance with the maximum contaminant levels listed in subparts 5-1.61 through 5-1.65, Part 5 Title 10 of the State of New York, Official Compilation of Rules and Regulations. The treatment system will be comprised of activated carbon filtration, anion and cation exhange demineralizers, and disinfection by sodium hypochlorite. Activated carbon filter backwash and demineralizer regeneration vastes are collected in a holding sump, and are removed offsite for disposal by a licensed contractor. During peak use, the total vastewater volume from the temporary potable water treatment system used for the first 2 years of construction, is approximacely 5,000 gal per day. Approximate waste composition is as follows: Parameter Conenntration Total dissolved solids 9,700 mg/l Total suspended solids 30 mg/l pH 3-11 (range, pH units) Chemicals required for operating the water treatment system during peak demand are as follows: Quantity Used Chemical 11b per day) Sulfuric acid, 93 percent 240 Sadium hydroxide, 30 percent 216 Sodium hypochlorite 0.24 Water from excavation dewatering, carbon filter backwash from potable water treatment (approximately 2 years after the start of construction), and storm water runoff vill be treated for suspended solids removal in sediment detention basin No. 1 (Tigure 3.1-15). Carbon filter backwash volume from the potable water treatment system will be approximately 3,200 gpd during peak use. The quality of water from excavation devatoring is expected to exhibit considerable variability, since it is dependent on many variables, including weather conditions, current work in progress, and ground water seepage. Figures 3.1-15A and B show the location of sediment detention basin Nos. 2 and 3 which will also be used to treat stormwater runoff from other construction areas, as shown. Treatment of runoff during construction is described in Section 4.1.4.1.1.2. Stormwater runoff outflow rates will be variable depending upon the intensity and duration of the storm. Effluents from the sediment detention basin will comply with the guidelines expressed in New York State Department of Energy Conservation policies and Procedures Manual Title 9100 Water Quality. Table 1 (Effluent Standards for Discharges -s Intermittent Streams), with the following exceptions: Amendment 3 4.1-3 June 1979

NYSEtG ER NEW HAVEN-NUCLEAR Maximum Concentration suspended Solids <50 mg/l Settleable solids Not applicable oil <29 mg/l During the excavation and backfill phase, no major ground devatering problems are anticipated. p.ock removal for building foundations vill be in relatively impermeable rock. The accumulation of water in the site structure excavations will result frem ground water seepage through excavation walls and floors. The total seepage quantity is calculated to be about 140 gpm (Section 6.1.2.2). A value of 200 gpm is used as the maximum seasonal flow from the excavation devatering system. This is conservative with respect to the calculated value and should accommodate any additional water inflow resulting from localiz J subsurface conditions. Excavation dewatering can be handled by sump pumps within the excavation. Water from the sump pumps vill be discharged into sediment detention basin No. 1, Figure 3.1-15A for clarification before being discharged into the diverted stream onsite. Dewatering of structure excavations is not expected to depress the ground water levels offsite because of the impervious nature of the rock. Waste washwater from the concrete handing equipment is treated and then reused for both vashwater purposes and for dust suppression on temporary onsite haul roads and construction areas. Waste washwater flows are expected to average approximately 750 gpd, with a maximum rate of 3,000 gpd. The vaste washwater vill centain up to 160,000 mg/l of suspended solids c oa ' consisting of sand, aggregate, and fine cement particles, and having c pH of approximately 10.0 to 12.0'ob', Waste washwater is conveyed to a ramped sump for removal of coarse sand and aggregate. Supernutant from the sump will be conveyed to a settling basin of approximately 150,000 gal capacity. Clarified water from the settling basin vill periodically be discharged to a clearvell basin of approximately 75,000 gal capacity. Water from the clearwell vill be periodically pumped to the concrete handling equipment for reuse, or to sprinkling trucks. The coarse material removed by the ramped sump and settled fines in the settling basin will be periodically cleaned and disposed of onsite as landfill. Most cements contain 90 to 95 percent of materials smaller than 74 u'ec'. The majority of these fine cement particles will deposit on the sedimentation basin and clearvell sidewalls and floor, thereby coating the interior surfaces with a thick, cementitious layer. The basin and clearwall vill be excavated within a deposit of ablation till, the properties of which are discussed in Section 2.5.4.2.4. Field percolation tests within the deposit indicated an average coefficient of permeability of 10-" cm/sec. It is expected that the sedimentation basin and clearvell side walls and floor vill quickly become impermeable upen operation of the treatment equipment.

When construction of the sewage treatment plant and discharge facilities are complete, treated sewage vill be discharged to Lake Ontario. The sewage treatment plant will provide secondary treatment in accordance with federal (40CFR133) and state (DEC Policies and Procedures Manual, Title 9200, Chapter 9210) limi t a ti o ns . Maximum daily scuage loadings are expected to be 90,000 gpd and 257 lb BOD per day during peak construction activity, based on per capita rates of 20 gal / person / day and 0.057 lb BOD / person / day. Estimated characteristics of sanitary vastes are provided in Tables 4.1-1 and 4.1-2. Maste biological solids will be hauled offsite for disposal by a licensed contractor. During the peak sewage flow period, the vaste biological solids production is estimated to be 880 gpd, at 2 percent solids concentration. Section 3.7 describes the sewage treatment plant process and expected effluent quality. Used oil, hydraulic fluids, vaste paint, thinners and similar materials will be collected and periodically transported offsite for reclamation or disposal by a licensed contractor. 4.1.1.7 Chemical Spills Durin2 Construction During construction, storage of lubricants, oils, and chemicals above ground vill be within dnclosed facilities as noted in Table 4.1-16. Storage areas within these facilities, except small containerized storage within enclosed trailers, vill be on a concrete pad with concrete spill containment curbs. The volume -ontained by the curbed area vill be at least equal to the volume of the single largest vessel stored in the curbed area. Any spillage within these dikes vill be reclaimed or disposed of offsite. Offsite disposal vill be performed only be contractors licensed by the State of New York. Fuel for construction vehicles vill be stored onsite in buried tanks. Fuel l vill be dispensed from these tanks by conventional service station pumps to mobile tank trucks which will service,the construction equipment. Surface spillage of fuel would be contained at the point of spillage and cleaned up manually. Underground spills, which would affect a small area, would be cleaned up by excavating the contaminated soil and backfilling with clean materials. Excavated materials vould be disposed of in a DEC approved landfill. Expected storage locations for construction lubricants, oils, and chemicals are shown in Figura 4.1=13. 4.1.1.8 Excavation and Land Filline Clearing operations (intermittently) are the first activity at the site and are completed in approximately 9 months. Marketable timber vill be harvested and sold if buyers can be found. Other timber and brush will be chipped and mulched, or burned onsite.

Standard heavy earth-moving aquipment is used for overburden excavation operatien. Sprinkler trucks provide dust control during this phase and, as necessary, throughout the construction program. The use of explosives during construction conforms to Occupational Safety and Health Administration and local regulations. A licensed blasting specialist designs the project blasting plan and the individual blasts. Blasts are matted where possible to minimize fly rock and dust. 4.1.1.9 Construction in Adiacent Water Bodies The construction of the temporary intake and discharge as shown in Figure 3.4-4 vill consist of:

3. Installation of armor stone on top of trench for protection against ice damage.
Maximun size anticipated for each tempo.rary pipeline is 12-inch outside diameter. The trench for the temporary intake and discharge pipelines extending into Lake Ontario will be excavated with a dragline. The subaqueous segment of the trench will be approximately 2,000 ft long, 4 ft deep, and 4 ft vide. Approximately 1,200 cu yd of lake bottom material, consisting primarily of gravelly sands and silty sands, will be 1ccally displaced to the sides of the trench rather than removed and stored. Following installation of the pipelines, the trench will be backfilled with clean sand and capped with armor stone. Shoreline excavation to the pumphouse area vill be done with a backhoe. The material excavated for the trench will be used as backfill after installation of the pipelines.

Installation of an inlet structure The discharge structures will be prefabricated on shore, barged out, sunk and set in place in predrilled vertical shafts at specific locations along the rock tunnel route. The vertical shafts vill be drilled in the vet utilizing a mobile, self-elevating construction platform. Lake bottom activities anticipated to construct each discharge structure include local removal of overburden and placement of a tremie concrete seal mat prior to drilling the vertical shafts for the discharge structure risers. After the steel pipe discharge structures are set in the vertical shafts and grouted in place, _he risers vill be encased in concrete using the tremie method and sheet metal forms.
The inlet structure, with an attached temporary steel caisson, will be prefabricated on a barge, barged out, sunk, and set in place on a prepared tremie concrete seal mat at its designated location. Lake bottom activities anticipated to construct the inlet structure include local removal of overburden and placement of a tremie concrete seal mat prior to sinking the inlet structure in place. Installation of rock anchors on the lake bottom is also anticipated for use in stabilizing the attached steel caisson. Drilling of the vertical shaft to connect the inlet structure with the rock tunnel vill be done in the dry after devatering the caisson and sealed inlet structure. After construction of the inlet structure, the caisson vill be removed. The makeup and blevdown pipe line vill cross the tributary to Catfish Creek in two locations. Prior to crossing the tributary, that portion of the stream to be crossed vill be temperarily diverted. The temporary diversion channel vill be excavated and stabilized with jute mesh, sod, or other suitable materials. Flow diversion vill be accomplished by blocking the existing stream channel with sandbags or other suitable dike material adjacent to the diversion inlet and outlet locations. Following installation of the makeup /blevdown pipelines at the stream crossing, the stream bed and embankments vill be restored and stabilized with gravel, rock, mulch, and seed or other suitable materials.

NYSE1G ER NEW HAVEN-NUCLEAR 4.1.1.10 Water Use Construction water requirements include water for dust control, building services, concrete production, soil compaction, fire protection, and domestic purposes. Construction water demand will be a maximum of approximately 250 gpm and will be primarily used for drinking water, sanitary water supply, and concrete production. During the first 2 years of construction, a lesser quantity (about 50 gpm) of water is required and this water will be drawn from wells onsite and processed through a package treatment facility to meet the New York State drinking water standards for community water supplies. After construction of a temporary intake and pump system has been completed, the balance of construction water vill be obtained from Lake Ontario. Potable water, taken from wells and Lake Ontario, will be treated by the package system using filtration by activated carbon, followed by disinfection by sodium hypochlorite. Permanent fire nrotection storage tanks and yard fire protection vill be established as sc.n as excavation and backfill operations permit, and will be maintained for use during the remainder of the construction program. Makeup for this system will be from the construction water system until the permanent plant makeup water intake structure and associated systems are complete. 4.1.1.11 Erecoerational cleaninn and Testinz Subsequent to installation and prior to operation, all reactor plant and turbine plant systems are cleaned by flushing with the fluid normally in the system (i.e., water is used in water systems and air is used in air systems). Closed-loop water systems will be flushed with demineralized water by recirculating this water throughout the system. Temporary filters and/or strainers will be used to verify system cleanness meeting the requirements of ANSI N45.2.1 (1973), and to prevent either the potential discharge to receiving water, or recirculation of foreign matter. Systems such as the circulating water system and the reactor plant service water system vill use rav vater and the recirculation technique for flushing. The total quantity of water vill be minimized by the recirculation technique, such that the estimated quantity of spent flush water (i.e., demineralized and rav vater) finally discharged to Lake Ontario will be approximately 5,000,000 gal. Cleanness control, through the use of industry standards such as ANSI N45.2.1, N45.2.2, and N45.2.3, ensures a high degree of cleanness in the various piping systems during manufacture, shipment, onsite storage, and installation. Accordingly, the preoperational water flush will not remove any significant quantities of foreign matter. Sulfuric acid and socium hydroxide quantities required to chemically regenerate the makeup demineralizers, were conservatively estimated by assuming that the total flush water requirement of 5,000,000 gal are of domineralized water quality. The total quantity of the demineralizer regeneration vaste is approximately 0.5 million gallons.

The pH of the demineralizer regeneration vaste is adjusted to within 6.0 to 9.0 by the vaste neutralizing system (refer to Section 3.6.1.2, New Haven-Nuclear, Amendment 3). The composition of the neutralized demineralizer regeneration vaste is indicated in Table 3.6-2. Due to the various cleanness control procedures described above, the use of temporary strainers and filters, and the use of demineralized water or rav vater where appropriate, the composition of the spent flush water is expected to comply with the following discharge criteria indicated in 40CTR423 for metal cleaning vaste, without treatment: Daily Maximum Average 30 Day Parameter Concentration Concentration Total suspended solids (ISS) 100 mg/l 30 mg/l 011 and grease 20 mg/l 15 mg/l Copper, total 1.0 mg/l 1.C mg/l Iron, total 1.0 mg/l 1.0 mg/l Spent or recirculating flush water stored in two of the domineralized water storage tanks will be discharged to Lake Ontario along with neutralized regeneratien vaste via the permanent cooling tower blowdown. Preoperational flushing vill accer over an approximate rine menth period. Discharges from these operations will be intermittenc. It is not possible to accurately predict the vastewater discharge frequency; however, maximum discharge flows for spent flushwater and neutralized demineralizer regeneration vaste are 300 gpm and 100 gpm, respectively. The neutralized demineralizer regeneration vaste vill be monitored for pH and TSS as described in Section 3.6.1.2, New Haven-Neclear, Amendment 3. Spent flushwater vill be periodically monitored for TSS and iron. The treatment and discharge of floor and equipment drainage, which may result in part from infrequent floor rinsing, are described in Section 3.6.3, New Haven-Nuclear, Amendesnt 3. There are no other planned or expected cleaning operations resulting in the discharge of vaste waters. 4.1.2 Land Use and Environmental Imoacts of Site Precaration and Station Construction 4.1.2.1 Disrvetion of Site Area Land Uses Onsite land uses are ggricultural, commercial, and residential with areas of voodlands and shrublands *as described in Section 2.1.3.1.

The remaining four species were permanent or summer residents which nested on the site. Even though the habitats used by these birds will not be eliminated by the proposed project, any reduction in habitat will mean displacement of individuals. A brief discussion of the probable impact on each species is presented below. A pair of American kestrel were regularly observed in the swamp cover type just south of the abandoned railrcad grade. The birds apparently nested in a cavity in one of the many dead trees present in this area. This specific area vill not be clininated if the facility is constructed. The dead trees containing the cavities, however, will probably not remain standing for more than another decade (they will eventually decay or fall). The American kestrel typically feeds in open fields, frequently perching on transmission lines. The eventual disappearance of open fields on the site through the process of floral succession will eliminate most of the onsite open field habitat. This open habitat is common in the site region, and the impact of station construction on the American kestrel is considered insignificant. The American kestrel has been placed on the Blue List because of declines in itt population primarily in Florida and the Gulf States' 2"' . Tive red-headed woodpeckers were regularly observed in the same area as the American kestrels. The red-headed woodpecker is apparently uncommon in Oswego County'2, and concern for it is widerpread427'. This woodpecker breeds in rivet bottoms, near beaver ponds, in open wooded swamps where dead trees and stumps are plentiful, in open savanna-like country with extensive grassland and scattered trees, and in cleared upland areasta. Bull ( 2 indicates that in addition to habitat reduction, roadside mortality and usurpation of nest holes by starlings may contribute to the recent declinc of the red-headed woodpecker. The construction of the station will not eliminate the area where l the red-headed woodpecker is currently found. The long term onsite presence of the red-headed woodpecker is, however, in doubt because many of the dead l trees in which it might be nesting are likely to decay or fall within the next decade. Howevet, there are other similar dead trees in the vicinity of the site which might be used, particularly near Eutterfly Swamp. Hairy woodpeckers were regularly observed during all seasons. Ornithologists are primarily concerned about this woodpecker's population trend in Florida, the Southern Great Plains, and South Texas, where populations appear to be decliningi27'. Hairy woodpeckers nest in dead trees, usually in extensive tracts of forest where large trees, dead stubs, and fallen logs are abundant 82. Even though the woodlands onsite are not extensive, this species was regularly observed in all seasons. Although its total numbers are certain to be reduced ac a result of clearing of woodlands, the occurrence of extensive woodlands in the region should make the impact of station construction minimal. The yeliow warbler was extremely abundant onsite from spring to fall. Concern for this species is varied; seme ornithologists relieve that continent-wide population is declining <2r> . The species is an adaptable breeder and nests in garden shrubb r , bushes, trees, and dense Flickets'2. The clearing of Amendment }

NYS E!G -ER NEW HAVEN-NUCLEAR onsite shrub cc munities is expected to reduce temporarily the number of yellow varblers nesting onsite. The effect of this impact is expected to be negligible, however, because of the large amount of shrub habitat available in the site region. The development of shrub coumunities that will begin when farming activities end vill increase the onsite nesting habitat for yellow varbler within 5 to 10 years after construction begins. 4.1.3.4.9 Effects en Recreationally Imoortant Species of the three cpecies of upland gamebirds inhabiting the site, the vuodcock and ruffed grouse vill be most significantly affected. The existing shrub and second growth woodlands onsite provide excellent habitat for both. The loss of the onsite woodland and shrub cc munities will temporarily reduce this habitat. This loss vill be compensated for by the development of similar communities on und sturbed portions of the site. The effect will not be significant from a regional perspective because the region includes a large amount of this habitat. The ring-necked pheasant, the third upland species, is not abundant onsite or in the region of the site, even though considerable habitat in the form of old fields and agricultural fields is available. The cessation of farming acti*ities vill completely eliminate the onsite habitat for the pheasant, because fields wi ll be replaced by shrub cc munities. Because the pheasant populations in the site region are lov, no significant effect on the total pheasant population is expected. Because the area of vetland habitat onsite is relatively small (less than 10 acres), the occurrence of waterfowl onsite is primarily incidental. No significant effect is expected. The erstern cottontail is the most abundant game mammal onsite. A mixture of cropland, grassland, brushland, and cut-over woodlands is ideal habitat'ic) . Clearing such areas on the site vill reduce the onsite habitat for the eastern cottontail and reduce the total ansite population. However, this reduction may be mitigated to some degree by later restoration of temporarily disturbed areas. The effect on the abundance of the eastern cottontail in the site area should be negligible, however, because me:h of the surrounding land is a similar mixture of cropland, grassland, brrshland, and cut-over woodlands. The gray squirrel and unite-tailed deer also occur on the site. Clearing vegetation will reduce the h a'o i t a t avaliable for these species; however, because their numbers on the site are lov, the reduction of available habitat is expected to have a minimal effect ta ti.e populations of these species in the vicinity of the site. Trapping is conducted onsite f or several mammal species (Section 2.2.1.6). Muskrat, raccoon, and mink have been taken along 3utterfly and Catfish Creeks. The relocation of a tributary of Tatfish Creek will reduce the habitat available for these species. The oncite populations of these mammals appear to be low; few were : rapped along the portion of the streams to be affected. Therefore, the impact on the local regional population is not expected to be significant. The site vill be permanently closed to hunting and trapping when station construction begins. i.

Construction of the .s t e a.n diversion is described further in Section 4.1.4.1.1.2 as part of the conceptual erosion and sedimentation control plans. Construction of the stream diversion will take place in three phases which will facilitate implementing various arosion and sedimentation control measures. Measures which will minimize turbidity in the portion of Catfish Creek, downstream of the diversion include the following:
1. For each portion of the stream diversion completed during each phase of construction, the diversion channel and side slopes will be stabilized as soon as possible after excavation and grading.

2. Where possible, all discharges resulting from runoff from construction areas are discharged to the Catfish Creek tributary either downstream of any portion of the diversion undar construction, or are discharged to stabilized portions of the diversion.

3. Three sediment detention basins will be used, and temporary protective measures such as straw bales or filter berms will be employed to minimize the introduction of sediment-laden storm water to the diversion channel.
The aquatic impact associated with this type of a stream diversion will be minimal. Loss of the original stream bed througt diversion of the Catfish Creek tributary will not ressit in any unique habitat or species losses for fish or benthic macroinvertebrates. Organisms encountered in the stream sections to be rerouted were also present upstream of these areas. Therefore, they stil be available to colonize the new stream bed. Sport fish were not encountered in any of the areas to be diverted. The effect of stream diversion on water quality wilt be exhibited directly as changes in concentrations of total suspended solids released during construction and temperature changes induced by changes in vegetative cover or stream depth and width. Because of the shallowness of the stream and the aeration, temperature changes would not have an effect on dissolved oxygen l concentrations. Therefore, this alteration should not stress the biological community. Turbidity levels associated with stream diversion are difficult to predict because of the many variables existing at the time of the actual diversion. The effect of turbidity on aquatic biota downstream from the diversion is minimal because of its short duration. The permanent loss of approximately 1,200 ft of the intermittent tributary to Catfish Creek will not seriously impact the aquatic ecosystem. The existing stream course of the Catfish Creek tributaries and the diversion channel are delineated in Figures 3.1-15 and 3.1-15A. These streams have been designated as Class D vaters<>ca) .

NYSE8G ER NEW HAVEN-NUCLEAR Sll and 3 also provided evidence for zero flow conditions (Appendix Table 2.4A-10). The tributaries of Catfish Creek are common from the standpoint of biotic resources in the area and are not used for spawning by migrant species of fish from Lake Ontario. The mill dam on Catfish Creek at North Road is an effective barrier to fish movement from that point. No onsite permanent diversion of the west branch of the Catfish Creek tributary will be necessary. The stream bed of this intermittent stream in the vicinity of the top sofi storage and spoils area (Refer to rigure 3.1-15A) will require restoration at its entrance to the diverted stream channel and at the makeup / blowdown pipeline crossing. Temporary diversion of stream flow is required to perform this work. The temporary channel will be stablized with jute mesh or sodding. The restored portions of the stream bed and embankments will be stabilized with seeding, gravel or stone prior to restoring flow through the stream. The construction of the makeup and blowdown line will require two crossings of the Catfish Creek tributary as described in Section 4.1.1.9. Aquatic impact relative to these diversions will be both short-term and reversible due to the relatively small portions of existing stream bed to be disturbed and the short duration of the diversions. Impact will, therefore, be confined to the loss of a small portion of the existing stream benthic habitat and a very short period of elevated levels of suspended solids due to construction activity. Once the stream course is restored, recolonization of the disturbed bottom will renew the benthic population lost during the diversion. 4.1.4.1.1.2 Site Runof[ The conceptual runoff and erosion control program will be implemented in three phases which are outlined below. Areas of construction associated with each l phase, the locations of sediment detention basins No. 1, 2 , and 3, and runoff routes are shown in Figures 3.1-15, 3.1-15A, and 3.;-153. Each phase of the program is desi[ned to isolate runoff in the main site work areas and to collect and convey potentially contaminated runoff from these areas to sediment control facilities. Runoff f rom undisturbed portions of the site will, where feasible, be diverted away from site construction areas. The design stormwater runoff volumes which discharge to sediment detention basins No. 1, 2 , and 3, from the one in 10 yr, 24-hr storm, are 23.1, 23.1, and 8.4 acre-ft, respectively. These volumes were determined based on the respective drainage areas shown in Figures 3.1-15 and 3.1-15A, a one in 10-yr, 24-hr storm of 3.' in,'' and a runoff,c.oefficient of 0.5."> The sediment detention basins are designed and maintained to contain the entire quantity of water from this design runoff event. Outfall design will either be of the perforated riser pipe type, or will utilize a rectangular weir overflow. Detention times will be variable since they are dependent on a number of factors including rainfall intensity. Sediment detention basin design will incorporate the recommendations of the State of New York,585* and the EPA.'

Phase I Major construction activities associated with Phase I are shown in Figure 3.1-15A. The construction activities for which the Phase I program is designed include construction of temporary access roads, general site grading in the power block, batch plant, laydown and 345 kV switchyard areas, and related filling and topsoil stockpiling to dispose of excavated materials. The onsite portion of existing Catfish Creek tributary will be temporarily relocated along the alignment of the main entrance road, and the northernmost portion of the permanent diversion channel for Catfish Creek tributary will be excavated and stabilized. During Phase I, the flow from the tributary will be diverted into this section of the permanent diversion channel. Measures that will be taken to control runoff and erosion from these operations are described below. Runoff from Area A vill be directed to sediment detention basin No. 1. This has a minimum capacity of approximately 23.1 acre-ft. Water is dis harged l from the basin into the temporary channel of Catfish Creek tributary. In Area B, strav bales, filter berms, or the equivalent will be provided around those sections where runoff vill originate. These temporary protective measures will be maintained until vegetative cover has been established. A portion of this runoff vill be discharged to Catfish Creek, and the remainder vill be conveyed over natural drainage contours to Butterfly Creek. Area C vill be graded toward sediment detention basin No. 2. This excavated basin has a minimum capacity of approximately 23.1 acre-ft. Water from this l basin discharges into the temporary channel of Catfish Creek tributary. Area D will be graded to drain vest to the permanent diversion channel of Catfish Creek tributary. Strav bales, filter berms, or the equivalent will be provided across the path of runoff from this area and will be maintained until vegetative cover has been established. Area E is graded to conduct potentially centaminated runoff to sediment detention basin No. 3. This basin is formed by excavation within a horseshoe - shaped dike, and has a minimum capacity of approximately 8.4 acre-ft. '7ater is discharged f rom the basin into the permanent diversion channel for Catfish Creek tributary. At Area F, strav bales, filter berms, or the equivalent will be placed across the path of runoff from the topsoil piles.

The construction activities for which the Phase II program is designed include construction of the 765 kV switchyard and most of the pe rmane nt diversion channel for Catfish Creek tributary. Excavated materials vill be placed in topsoil storage, spoils, and landscaped landform areas indicated in Figure 3.1-153. Vegetative cover will be established in these areas as soon as possible. The phase I erosion and sedimentation control measures vill continue in effect, with the following additions. Sediment detention basins Nos. 2 and 3 vill be maintained during excavation of sections of the permanent diversion channel upstream from these basins. Channel excavation vill proceed in the upstream direction. This increases the capacity of sediment detention basins Nos. 2 and 3, and directs runoff from the channel excavation to these basins. The chant.el vill be stabilized as excavation proceeds upstream, and the slopes above the channel vill be topsoiled and seeded. Area C is extended to include all of tha 765 kV switchyard and the landscaped landform areas surrounding the switchyards. Strav bales, filter berms, or the equivalent will be placed across tr e path of runoff from the areas affected by excavation and fill placement. Runoff from the 765 kV switchyard, and from the northern slopes of the adjacent landscaped landform areas, flows to sediment detention basin No. 2. Runoff from the southern slope of these steas flows into the temporary channel of the Catfish Creek tributary. Phase Ill rigure 3.1-15 shows the major construction activities near the end of Phase III. The Phase III ercsion and sedimentation control program completes the permanent diversion channel for Catfish Creek tributary, and transfers the tributary's flow into the permanent channel. To accomplish this, the sediment in sediment c'etention basin No. 3 is removed to a spoils area. The basin dike is also removed, and this section of the permanent diversion channel is graded and stabilized. The channel section at sediment detention basin No. 2 is then completed in a similar manner. After these sections of the permanent diversica channel have been compJeted, the temporary Catfish Creek tributary is diverted into the permanent channel. During Phase :II, some additional fill vill be placed in the spoil and landscaped landform areas. Temporary protective measures such as straw bales or filter berts vill be placed across runoff flow paths from these areas. Increased siltttion, caused by higher levels of total suspended solids in site runoff, could affect aquatic organisms. Site runoff from disturbed areas will be treated in onsite sediment detention basins (Section 4.1.1) to remove suspended solids before the runoff enters the diverted stream. Suspended solids in the effluent from the basins are not expected to exceed 50 mg/l (Section 4.1.1.6). Onsite organisms or downstream communities vill not be affected by increases in suspended solids, because only minor increases in ambient concentrations are expected.

Table 4.1-9 rummarizes available data on effects of total suspended solids on aquatic biota. The results presented in the table, however, are evaluated effects over long periods of time, whereas maximum effluent TSS concentration from the site is expected to occur only during storm periods of short duration, and exceed observed ambient maximum TSS concentrations by no more than 7 mg/1. The slight increase in turbidity for short periods is not expected to have an adverse affect on the biota in the downstream portions of Catfish Creek. 4.1.4.1.2 Source and Receivinz Water Body Figure 3.4-4 shows areas of construction in Lake Ontario.

Tunneling will eliminate impact upon the relatively more biologically productive inshore habitat. The loss of benthic habitat will be limited to the sites of the velocity cap intake structure and the discharge diffuser. These areas are a small portion (approximately 300 sq ft) of the lake bottom which is available to macroinvertebrates. Initial constructicn will eliminate approximately 1.7 x 10' macroinvertebrates, with a biomass of 7.0 g (ash-free dry weight of Eantarus sp., Sphaeriidae and Gastropoda) which represents approximately 0.15 x 10-8 percent of the mean biomass in the study area (Section 2.2.2.1.5.8 and Appendix Tables 2.2D-36 through 2.2D-55). Physical disruption of Lake Ontario bottom sediments during placement of the discharge diffuser and inlet will temporarily increase levels of solids in the immediate area. The bottom sediment in this area is mostly sand underlined with sedimentary rock (Section 2.4.1.1.8). Since the sediment is relatively free of silt and clay, settling of the resuspended solids should occur within a short period of time and elevated turbidity will be temporary and localized. Effects of construction on other forms of aquatic life near the inlet structure and discharge diffuser will be short term and localized. Plankton populations may be temporarily affected by increased turbidity, but as described above, turbidity should dissipate rapidly because of the nature of the sediments to be disturbed. Effects on the periphytic algal community will be very limited because little attached algae grows at the 30-ft depth contour (Section 2.2.2.1.3). Likewise, ichthyoplankton populations are expected to be impacted only minimally, because densities were generally low at the 30-ft contour (Section 2.2.2.1.7) and because of the small areas affected. Adult and juvenile fish should not be adversely impacted becauce their mobility which will enable them to avoid areas of construction activity. The overall impact of this construction activity on the aquatic organisms will be minimal. During construction, , water will be obtained from onsite wells for the first 2 years.

This small quantity of water is not expected to have an impact on Lake Ontario biota. The construction of the trench to lay the temporary construction water intake and discharge pipelines will have only a temporary effect on the aquatic organisms along an approximately 2000-ft path in the lake. The overall effects will be similar to those discussed for the inlet structure and discharge diffuser. The discharge of sanitary vastes into Lake Ontario during construction vill meet applicable State and Federal regulations (Section %.1.1) and vill not be expected to impact the aquatic biota. 4.1.4.2 Elter Outlity Environmental Impacts 4.1.4.2.1 Effluent DischarRes Various procedures vill be used to control erosion and 2edimentation associated with construction activities. The erosion control plan, including the sediment detention basins, and the discharge locations are described in Section 4.l.4.1.1.2, and summarized in Section 4.5. The basins vill creat runoff from major site construction areas and water flom major onsite excavation devatering. The basins are designed to treat the volume of runoff that would result from a 10-year, 24-hr storm. Effluent from the basins vill meet the requirements in 40CTR423 with a suspended solids concentration no greater than 50 mg/1. Once clarified, the effluent will be discharged to Catfish Creek via the diverted stream. Due to the low level of suspended solids in this effluent, there vill be no adverse impact to these water courses or to Lake Ontario. The sediment detention casins will have emergency spillways to handle runoff during conditions that exceed design. During such conditions runoff into watercourses and Lake Ontario from natural sources will contain high concentrations of suspended material. In such a situation, the incremental runoff added from the emergency spillways will have an insignificant effect on the water quality of the water courses on the lake in light of the high sediment load carried by other sources into the water courses and lake. During the initial stages of construction, chemical toilets are used, thus eliminating the need for the discharge of any sanitary vastes. A sanitary vaste treatment plant that provides secondary treatment vill be operaticnal after the second year of construction. (A description of the sanitary vaste treatment system is presented in Section 3.7.) Treated effluent from this plant will satisfy 1. the New York State requirements, as promulgated in plant Section 17-0509 of the Environmental Conservation Law and 2. the federal criteria set forth in 40CTR133. The effluent will be discharged into Lake Ontario through a temporary piping system. The maximum flow of sanitary vastes through the treatment plant vill be approximately 45,000 spd. Because the sanitary discharges are small and vill be adequately treated, the water quality of Lake Ontario will not be adversely affected.

The sediments to be disturbed are gravelly and silty sands. The sand portion of the sediments will settle rapidly without increasing turbidity outside of the immediate area. Any silt size particles will remain in the water column longer than the sand. However, increases in turbidity will occur only in proximity to, and for approximately the daily duration of active excavation. The entire trenching activity is estimated to require 6 weeks, thus any effects will be temporary. Lake bottom contours will not be permanently altered by installation of the temporary intake / discharge pipeline. Lake flow will not be changed by construction of the temporary intake / discharge structures. The cumulative hydrologic impact of the temporary intake / discharge system is negligible. Shoreline excavation f~ the temporary system will be of limited duration and extent. Relatively sm .1 amounts of soil or sediment will be disturbed and released into Lake Ontario.

The rock extracted during this process will be used in the construction of the pumphouse or as fill material around the station. There are no plans for other construction activites that might significantly affect the water quality of Lake Ontario. 4.1.4.2.3 Relocation of Onsite Straams The construction of the station will require the relocation of a tributary of Catfish Creek, as described in Section 4.1.4.1.1.

The assessment of the noise impacts from station construction includes a characterization of the existing acoustical environment (Section 2.7), an analysis of the noise from the construction site, and an evaluation of the effects of the construction noise on the receptors in the area. Onsite construction activities can be categorized as either continuous or intermittent. Generally speaking, continuous activities are those activities that occur regularly and set the long term levels of construction noise. Intermittent activities, although they can produce high noise levels, occur infrequently and generally do not affect the long term construction noise levels. The total construction noise emissions comprise the sound produced by the major noise sources associated with continuous and intermittent activities. The " major" sources cf construction noise are those sources which measurably contribute to the noise received by the surrounding community. The sections that folic > describe the techniques used to assess the noise impacts of constructing the proposed station. Section 4.1.5.2 discusses the major continuous onsite construction equipment, describes the methods used to predict continuous construction noise emissions, and evaluates the effects of such noise on the surrounding area. Intermittent and offsite construction activities and their impacts are discussed in Section 4.1.5.3. Offsite transportation associated with the station's construction and its impact is addressed in Section 4.1.5.4 The total noise impact on the community from all aspects of the station's construction is summarized in Section 4.1.5.5.

NYSE8G-ER NEW HAVEN-NUCLEAR The impact of the concrete batch plant, discussed in Section 4.1.6.1, on the ground level concentration of TSP has been estimated with a simple Gaussian diffusion equation, using hypothetical worst case veather conditions. Table 4.1-13 summarizes the batch plant emissions, assumptions, and formulae used in calculating the maximum 24-hr average TSP concentration, which is 1.86 ug/cu m at the nearest site boundary. This is less than 2 percent of the 150 ug/cu m 24-hr TSP Ambient Air Quality Standard (AAQS). The upvind edge of the proposed construction parking lot will be approximately 950 m from the nearest site boundary. Construction vorker vehicles will leave the parking lot by two exits that lead to two onsite roadways. This traffic will be regulated, after consultation with appropriate governmental agencies, to ensure a smooth flow of vehicles. For these reasons, there vill be no significant effect on any offsite receptor. The parking lot is considered a significant indirect source of air pollution under 6NYCRR203, which requires a mandatory review of air quality impacts of all pollutants emitted. Table 4.1-14 summarizes the parking lot emissions, assumptions, and methodology used in estimating impacts for construction worker vehicles. This analysis (using the method described in Guidelines for Air Quality Maintenance Planning and Analysis <"8' modified by corrections from Corpilation of Air Pollutant Emissions Factorsi") shows that the maximum 1-hr average C0 concentrations vould be 3.6 mg/cu m at the nearest site boundary. This is only 14 percent of the 1-hr CO AAQS of u0 mg/cu m. The 8-hr CO AAQS of 10 mg/cu m also could not be violated, since the maximum 1-hr parking lot concentrations vill occur for approximately 2 hr per day. Ambient CO concentrations are expected to be lov, as discussed in Section 2.3.7. The line of traffic formed at each of the two onsite access roads would cause a maximum 1-hr C0 concentration (at a point perpendicular to and 10 m downwind from the edge of the road segment) of 10.5 mg/cu m (Table 4.1-14) which is only 25. percent of the 1-hr CO AAOS. Since the line of traffic would exist for an hour or less, the 8-hr average standard would not be exceeded. The 1-hr impact of NOx was quantified in a manner similar to that for Co. The 1-hr average NOx concentration at the nearest site boundary to the parking lot will be 296.0 ug/cu m. This assures that the annual overage AAQS for nitrogen dioxide (N02) of 100 ug/cu m vill not be exceeded, since the maximum 1-hr parking lot concentrations will occur for at most 2 hr per day. Present ambient NO2 levels, as discussed in Section 2.3.7, do not exceed 12.6 ug/cu m at NYSE1G's monitoring Station B, which is the air quality monitoring station most representative uf site conditions. The impact of hydrocarbons (HC) was quantified in a similar manner. The 3-hr averate HC concentration at the nearest property line to the site boundary was shown to be 53.3 ug/cu m. This is only 33 percent of the 3-hr HC standard of 160 ug/cu m. Ambient concentrations of HC are expected to be lov because there are few local sources of HC. Permanent access roads used by the construction work force vill be paved and kept free of dust to reduce fugitive emissions.

Effects en Site MicrometnoroloRY The effect of construction on the micrometeorology of the area is expected to be insignificant. The removal of some onsite trees may alter the wind flow and turbulence characteristics, but the change would be minimal. Fugitive dust emissions and smoke may decrease visibility slightly. These effects are not long term and will not affect offsite micrometeorology. 4.1.7 Floodiny Environ ental Imeact During the early stages of construction, the stream flowing through the site (a tributary of Catfish Creek, as described in Section 4.1.4) will be diverted to a permanent channel. The permanent channel is designed to contain flows in excets of the 100-year flood. Accordingly, the construction area and access roads are protected from inundation by such flood flows. The effects of channel diversion will be evidenced by a minimal increase in flows conveyed in Catfish Creek Tributary F, downstream of the Tributary FE diversion. An analysis was performed using techniques described in "Model Hydrographs"<*2', in conjunction with runoff predictions of 50- and 100 year precipitation events made through the use of the HEC-1 computer program'***. This analysis indicated that the stream diversion would result in an increase in flows of approximately 1 percent at the mouth of Tributary F. This increase is primarily due to the decrease in the time of concentration as a result of shortening Tributary FE by approximately 1,200 ft when it is diverted to its permanent channel. Alterations in ground cover do not significantly affect overall hydrologic response of the basin associated with Tributary F, since the site area to be developed is small, approximately 7 percent of the total drainage bas in area of 3.18 sq mi. These changes are not expected to alter the present conditions with regard to fjooding environmental impact. 4.1.8 Ground Water Fatable water requirements (approximately 50 gpm) for initial construction activities will be supplied by a well located onsite. The well vill supply l potable water for approximately 2 years until a temporary line is constructed to Lake Ontario which would p rovide the balance of potable water during the remaining construction period. The well is located approximately 30 ft north of boring G-83 (Figure 2.5-34) on the east side of Butterfly Creek and is on the opposite side of Lee Road from domestic well No. 254 (Table 2.1-46 and Figure 2.5-18). The well is 6 inches in diameter and is drilled to a depth of 65 ft (35 ft into rock). Most of the well yield is derived from a highly jointed zone at the top of bedrock. 'Je ll recharge is primarily from infiltration of groundwater within the low area along Butterfly Creek. A pumping / recovery test was conducted for a 48-hr period at a pumping rate of 65 gpm. On the basis of this test, it is anticipated that the static pressure

NYSE8G ER NEW HA'/EN-NUCLEAR head within the jointed rock aquifer at veil No. 254 vill be reduced by approximately 15 ft. However, the water level (vater table) in the overburden aquifer vill drop only a few feet. Given the demand of only 2 to 5 spm typical for domestic wells, and the small dravdown associated with such flow, pumping of the potable water should have no impact upon the users of well No. 254 and other offsite wells. There are 53 private wells located within the site boundary (Table 2.1-46 and Tigure 2.1-18) and cumulatively they yield considerably more than 50 gpm. These wells vill be taken out of service or may be used selectively as part of the construction water supply system. No major devatering problems are anticipated during excavation and backfilling operations. Water vill be removed by ump pumps installed within the l excavation. Sediment detention basins will be used for clarification prior to discharge to surface waters. Excavation devatering should have no effect on ground water quality. As discussed in Section 2.4.2, the permeability of the overburden materials in the area of plant excavatians is low. Therefore, seepage vill have only a limited effect on groundwater levels onsite. As discussed in Section 6.1.2.2, groundwater levels are not expected to be affected 1,000 ft or more beyond the excavations. Additionally, the northwesterly flow through the site vill be essentially unchanged. Since groundwater quality should not be affected during construction, the groundwater monitoring program vill consist of monthly readings of water level only. Readings vill be taken in those existing observation wells not affected by construction activities (Figure 2.5-48). Wells presently located within the plant structure or construction facility areas (Figure 3.1-15) vill be abandoned. The remaining wells will be monitored to provide general data on site groundwater levels during excavation devatering. Additional wells will be installed as needed in areas of specific interest, such as the switchyard excavation slopes (Tigure 3.1-2) in order to monitor dravdown which could af f ect domastic vell perf ormance and to verify design groundwater levels. Butterfly Creek is located approximately 700 ft east of the Unit 2 reactor plant service water cooling tower. The normal water level in the creek at this point is about el +320 ms1. The ground water level at the location of the reactor plant service water cooling tower is el +340 (rigure 2.5-45). Foundation grade for the reactor plant service water cooling tower is el +295 (deepest excavation onsite) which is 25 ft lower than the water level in the creek. There are at least 15 ft of glacial till (boring S-21, Appendix 2.5C) underlying Butterfly Creek at its nearest approach to the site. The till increases in thickness to a maximum of 36 ft (boring G-12, Appendix 2.5C) between the creek and the Unit 2 reactor plant service water cooling tower. As discussed in Section 2.4.2, ground water movement is primarily in the upper 5 to 10 ft of jointed and detached rock slabs occurring at the bedrock surface. The bedrock surface rises from el +300 below Butterfly Creek (boring Amendment 3 * ' 4.1-63 bI June 1979 565.
NYSE8G ER NEW HAVEN-NUCLEAR S-21) at its nearest approach to the site, to el +333 (boring G-21) at the Unit 2 reactor plant service water cooling tower. The top of rock at the creek is 5 ft higher than the bottom of the reactor plant service water cooling tower excavation; however, the bedrock surface is 33 ft higher at the cooling tower. Field percolation and water pressure tests (Tables 2.5-6 and 2.5-9) indicate that the till and rock at depth (below 10 ft - the weathered zone at bedrock surface) are of low permeability. Dewatering of the Unit 2 reactor plant service water cooling tower excavation will cause a local depression in the ground water table. Ground water and/or surface water conditions at Butterfly Creek should not be affected due to the distance involved (7CO ft), the thickness (36 ft max) of impervious overburden materials between the creek and the site, the depth to rock at the creek (20 ft), and the eastward sloping bedrock surface. Several private wells (Figure 2.1-18) are located along Route 104 south of the excavation required for the switchyard (Figure 4.1-11). Both shallow dug wells (12 to 3B ft) and drilled wells (60 to 90 ft) are present in this area (Table *.1-15). Ground surface at the location of the wells ranges from el 410 to 435. The excavation for the switchyard will require a maximum cut of 40 ft (el 380 to 420) with the top of the cut slope located approximately 350 ft north of Route 104 Existing topography, planned final grade, and wells nearest the excavation are shown in Figure 4.1-11. Well Nos. 96, 98, 100, and 101 are located within the site boundary and vill be purchased and taken out of service prior to the start of construction. The site surficial map (Figure 2.5-19) and data obtained from the ground water users survey (Section 2.1.3.8) indicate that the wells south of the switchyard are located on a drumlin ridge which has a thick till core. Yields from wells in till are normally low, and shallow dug wells are subject to decreasing yields during dry seasons. In areas where till is extensive, or of considerable thickness, yields sufficient for domestic supplies are usually obtained from wells that penetrate the till/ rock contact. The switchyard excavation will cause a permanent lowering of the ground water table to the south. No change in the direction of ground water flow will occur as a result of the excavation, and no subsurface injection of water is planned. Thus, the excavation will have no effect on ground water quality. Drawdown model studies (Section 6.1.2.2) indicate that the effect will be local. The profile in Figure 4.1-12 shows site topography and ground water conditions prior to and after excavation of the switchyard. Existing elevations, depths, water levels, distance to the switchyard excavation, and predicted drawdowns for the nearest wells are summarized in Table 4.1-15. Wells Nos. 92, 95, 97, and 99 are deep-drilled wells of small diameter and lowering of the water level by 9 to 13 ft in these wells should have little effect on the total yield. However, lowering of the water level by 5 to 11 ft in the larger diameter, shallow dug wells (Well Nos. 89, 90, 91, 93, and 94) will decrease available storage capacity and may significantly reduce yields. In order to mitigate this inpact, new deep-drilled wells will be installed on the properties containing Well Nos. 89, 90, 91, 93, and 94 prior to the start of construction.

Other volls shown in Figure 4.1-11 are at greater distances from the switchyard excavation and will not be affected. Well Nos. 102 and 103 are deep-drilled wells located more than 1,000 ft southeast of the switchyard excavation. No reduction in water levcis or yields are anticipated in these wells because of the distance to the excavation and the depth of the wells. Well Nos. 84 to 88 are located over 900 ft southwest of the excavation on the opposite (west) side of an unnamed creek that drains a large svamp south of the wells. These wells vill not be affected by the switchyard excavation because of the distance to the excavation and their proximity to the svamp and the creek that flows between the wells and the switchyard. Prior to, during, and for at least 2 years after excavation of the switchyard, water level readings vill be taken in observation wells installed between the excavation and the nearest offsite users (Section 6.2.1.1.4), and in selected private vells located within the site boundary. Actual water level readings will be compared to the dravdowns predicted by the model study. The results of this monitoring program vill be included in the Environmental Report - Operating License Stage. There vill be essentially zero discharge to groundwater of washwater from the concrete equipment washwater treatment and reuse system.

NYSERG ER NEW HAVEN-NUCLEAR 4.5 CONSTRUCTION IMPACT CONTROL PROGRAM The following is a summary of mitigative and precautionary measures considered for controlling potential environmental impacts during the construction of the facility. The implementation of these measures are achieved by a detailed enforcement program which will be completed prior to the initiation of Construction. Most environmental impacts associated with construction activities are expected to be short term, approximately 7-1/2 years. Figure 3.1-15 shows the areas affected by construction. Preventive measures will be taken to minimize environmental impacts in these areas. 4.5.1 Mitigative Procrams 4.5.1.1 Noise Noise control for the construction site will be accomplished in several ways. Most construction activities which will be major sources of noise vill occur during the weekday daytime hours. Major internal combustion equipment will be equipped with properly installed mufflers. In addition, all equipment will comply with all applicable state and federal regulations. Building siding will be installed at the earliest possible.date to confine noise from interior construction activities. 4.5.1.2 Erosion Various methods will be usud to control soil erosion and sedimentation during construction (Section 4.1.4.1.1.2). To minimize soil erosion in cleared areas, protective material such as gravel, crushed stone, and pavement are used. Road shoulders are stabilized with crushed stone. Diversion ditches and berms will be used to prevent water from entering construction areas and to prevent water from flowing down unstabilized slopes. Soil loss is also controlled by nonstructural ertsures such as temporary vegetation or mulching with natural wood fibers, jute or excelsior matting, and straw bale barriers. The loss of topsoil is further minimized by the technique of stockpiling and stabilizing during the construction period. Runoff from vegetated and stabilized areas is diverted to vegetated buffer strips and existing drainage swales. The vegetated buffer strips filter out most of the suspended solids from runoff. Runoff from disturbed or unvegetated soils is directed to three sediment detention basins by a series of ditches and culverts as shown in Figures 3.1-15, 3.1-15a, and 3.1-15b. A temporary construction storm drainage system consisting of a network of drainage ditches and culverts collects runoff from areas of potentially high sediment loads and directs it to the appropriate sediment detention basin. Amendrent 3 4.5-1 E5b')GY' "d June 1979 {k0
NYSE8G ER NEW HAVEN-NUCLEAR The drainage ditches are lined with protective material such as crushed stone to minimize erosion. As construction progresses, the permanent drainage system and final grading are incorporated. A tributary of Catfish Creek, as described in Section 2.1.3.9, flows through the site and vill be diverted to the vestern boundary of the site. The diversion channel controls the runoff from the watershed immediately south of the site. This channel also intercepts other runoff toward the site and diverts the storm water to natural drainage areas. To miniaize erosion, the channel is lined with riprap and slopes are seeded with grass. Construction of the offsite makeup /blevdown pipeline vill progress in a continuous cut and cover operation thereby minimizing the extent of open excavations and allowing an ongoing process of stabilization and restoration of disturbed areas. Irosion control methods vill include the use of diversion ditches and berts to control runoff, straw bale barriers, filter berms, jute or excelsior matting, mulching, and seeding. Excavation devatering from groundwater or stormwater runoff vill be discharged to ditches adjacent to the excavation. The ditches will be designed te spread flow over vide areas of undisturbed ground and will not discharge directly to streams. Strav bale barriers vill be used to filter out most of the suspended solids prior to discharge over undisturbed areas. Construction access roadway alignment vill avoid,as much as possible, locations that vill collect large volumes of natural runoff. Construction of the offsite rail access is discussed in Section 4.1.1.4 Erosion control methods similar to those for construction of the makeup /blevdown pipeline vill be used. Strav bale barriers, filter berms, or the equivalent will be provided across the path of runoff from disturbed areas and vill be maintained until the disturbed area has been stabilized with vegetation, ballast, or crushed stone. 4.5.1.3 lus; After the initial site preparation vork is completed, the primary source of construction generated dust is expected to be the unpaved construction roads. Permanent roads within the site are established and stabilized during the early stages of construction to mininize dust problems. Traffic is limited to stabilized roads, when possible, and held to a minimum. Temporary construction haul roads within tae site will either be surfaced or periodically watered to minimize dust problems. Semipermanent roadways and parking areas are paved with asphalt or covered with crushed rock. Paved surfaces vill be cleaned periodically to minimize dust. Another potential source o# dust is vind erosion of c:. eared areas. The erosion control plan described in Section 4.5.1.2 vill also serve to control dust. The use of explosives during construction vill conform to OSHA regulations, and blasting vill be matted as neccssary to minimize flying rock and dust. Amendment 3 4.5-2 565ME June 1979
NYSE&G ER NEW HAVEN-NUCLEAR 4.5.1.4 Truck Traffic All traffic to and from the station uses the limited access road. Truck traffic, due to material deliveries, is scheduled during normal working hours. Deliveries are directed to the warehouse onsite for unloading either at the warehouse or into open storage. Truck traffic within the site is required to obey posted regulations and use construction roadways when possible. 4.3.1.5 Floodinz The site is not subject to flooding, as desccibed in Section 4.1.7. 4.5.1.6 Ground Water Dewatering of major onsite excavations below the groundwater table is done within the excavation by portable pumps. A series of ditches will convey groundwater, which seeps into the excavation to collection pits. Water in the pits is removed by portable pumps and discharged to the sediment detention basin. Strict control of the use of potential pollutants minimizes infiltration of pollutants to the groundwater. 4.5.1.7 Air and Water Quality The air quality impact during the construction of the station will be short term and is expected to be limited to the immediate site area. The largest impact to air quality is expected to be emissions from equipment used to support construction activities. This equipment will be properly maintained and controlled to minimize adverse effects. It is anticipated that some open burning vill be required to dispose of timber, brush, and shrubs resulting from land clearing which cannot be chipped and will continue throughout plant construction where no other practical disposal method exists. Open burning will be conducted in accordance with the following guidelines:
1. Appropriate local, county, and state officials will be contacted regarding the scheduled burning to learn of any temporary ban on open fires because of drought or related fire hazard conditions, or of an air pollution episode as described in 6NYCRR207.

2. Open burning operations will be performed to minimize: a) the number of slash piles burning; b) the number of days open burning is used; and c) active fires during darkness.

3. Open burning will be conducted during meteorologically appropriate periods.
Amendment 3 4.5-3 868 June 1979
NYSERG ER NEW HAVEN-NUCLEAR
~~4. Open burning sites will be attended whenever a fire is in progress or O~~
~~when hot ashes remain.~~
5. Lightweight petroleum products may be used to ignite slash piles.

6. Tires and other unsuitable materials will not be burned.
Concrete batching materials at the onsite batch plant are stored in accordance with applicable American Concrete Institute codes. The aggregate conveyor systems at the batch plant are enclosed, and the cement is stored in closed silos. Emissions from the batch plant will comply with 6NYCRR212-4(c). During the early stages of construction, a sediment detention basin is used for treating surface runoff from disturbed areas to remove suspended solids. Waste washwater from concrete handling equipment will be treated and then reused both as washwater and for dust suppression on onsite haul roads and construction areas. Construction of the diverted s' ream will be performed to minimize runoff or will incorporate a temporary impoundment to establish compliance with 40CTR423. Chemical toilets are initially prcvided for sanitary wastes. These wastes are collected on a regular basis and takaa off the site by a licensed contractor for proper treatment and disposal. As construction activities progress, toilet trailers or their equivalent with sewer and water connections are also employed. Drainage is made to a sewage treatment plant at the site. Sanitary waste water effluent will be discharged to Lake Ontario. The treated effluent will meet 40CTR133 and DEC requirements for fecal coliform bacteria in Policies and Procedures Manual, Title 9200, Chapter 9210. In outlying areas, chemical toilets are used throughout the duration of construction. 4.5.1.8 Tish and Wildlife Protection During construction of the station a number of measures will ensure minimal disruption of the plant and animal communities. With regard to the terrestrial environment, site access is limited to designated roads and traffic is confined to these roads and to specific parking areas as much as practicable. Construction materials are confined to specified laydown areas. These measures prevent indiscriminate disruption of the natural habitat by the construction work force. Wastes generated during construction are hauled to appropriate disposal areas or burned. Enclosing the major portion of the construction area with a chain link fence will keep most wildlife out of the area. Pesticides and herbicides used at the site during construction are chosen from those approved by the DEC. Following construction, all temporarily disturbed areas will be revegetated. t6 Amendment 3 4.5-4 June 1979 5851#
NYSE&G ER NEW HAVEN-NUCLEAR Impacts sustained by the aquatic environment due to construction are mainly those associated with increased turbidity caused by the construction of the makeup water inlet and binudown discharge system described in Sections 3.4.3 and 3.4.4, respectively. Section 4.1.1.7 describes the construction for the inlet and discharge structures. The small quantities of excavated material to set the inlet and discharge structures will be locally disposed of on the lake bottom. Tunneling the intake and discharge lines will eliminate turbidity caused by dredging, thus minimizing impact to the aquatic environment. Excavated material from the rock tunneling operation vill be used in the construction of the pumphouse or as fill material around the station. As discussed in Sections 4.1.3 and 4.1.4, the mitigative measures described above reduce any construction impacts to fish and wildlife to acceptable levels. 4.5.1.9 Archeolceical pesources As discussed in Section 2.6.2, there are no properties currently listed or currently being considered for the National Registry of National Landmarks or the National Register of Historic Places within the limits of station construction. The Applicant has contacted the State Historic Preservation Officer to determine if there are any historical or cultural properties currently under consideration for the National Register within the construction area. The Applicant has performed an archeological survey to evaluate the significance of archeological resources found on site. The results of the survey will be presented in a report to be completed oy early summer, 1979. After the appropriate agencies have reviewed the report and determined if there are any eligible properties for the National Register, the Applicant will (if eligible properties were identified) consult with the agencies to determine the effects of construction and appropriate mitigating measures to be taken. If the resources are significant and adversely impacted by the plant, the most probable and reasonable mitigation measure would be to extract the information available by having a professional archeologist(s) study the resource onsite before proceeding with construction. Depending upon the nature and significance of the resource, other measures including relocation of the resource might be implemented. The specific mitigation measure adopted for a particular resource vill depend on many factors. Specific mitigation measures will be determined through discussions with officials of the responsible agencies.

NYSE8G ER NEW HAVEN-NUCLEAR 375,000 fish (87.5 percent of the total). Rainbow smelt comprised an additional 26,000 fish (6 percent), threespine stickleback 15,000 (3.6 percent), and gizzard shad about 4,200 fish (1 percent). Remaining species combined comprised about 1.9 percent of the total. Highest estimated impingement will occur in April and May when alewives and rainbow smelt were inshore to spawn. A secondary peak comprised of young-of-the-year alewife and rainbow smelt will occur during the winter. 5.1.3.2.2.3 Combined Entrainment and Impingement Loss Estimates Equivalent adult losses, (based on estimates of entrainment) were added to impingement estimates to account for all impacts of the intake even though the impact of entrainment was shown to be negligible. At this point in the evaluation, it was necessary to divide Morone spp. larvae between white perch and white bass. Because 90 percent of the adult Morone spp. collected in Mexico Bay during 1977 (Section 2.2.2.1.6) were white porch, all equivalent adults were added to white perch. Some may have been white bass. The total estimated losses of fish equalled approximately 820,000 fish (390,000 equivalent adults and 430,000 impinged fish, Table 5.1-22). Alevives comprised 92 percent of the total, rainbow smelt 4 percent, and threespine stickleback 2 percent. All three numerically important species are forage fish in Lake Ontario; rainbow smelt hcve sport and commercial value as well. Other species having sport or commercial value included white bass, white perch, yellow perch, and lake herring. Highly prized sport fish such as trout, salmon, valleye, smallmouth bass, and brown bullhead, will not have been entrained or impinged because no larvae of these species were collected or less than one fish of these species per month were estimated to be impinged. The total number of fishes per species was multiplied by the mean weight of fish collected in the Mexico Bay study area during the year (Table 5.1-23). The mean weight of rainbow smelt collected during April and May 1977 was used because many young-of-the-year were collected later in the year, which resulted in a mean weight for the year of only 4.5 g. Weight of impinged burbot was used because few adults were collected. When possible, the total weight of fish loss was compared with lakevide biomass estimates'865 and combined New York and Canadian preliminary commercial landings for 1977857,5*> . The total weight of alewife lost equalled about 0.04 percent of the Lake Ontario biomass estimate. The total weight of rainbow smelt lost equalled about 0.006 percent of the bicmass estimate. These percentages were l relatively high since every effort was made to keep impingement and entrainment estimates conservative (vorst case) and the lakewide biomass estimates were stated by Schneider**b> to be conservatively low. The impact of impingement and entrainment on the two most numerically important species is therefore expected to be negligible. 1<6 b Amendment 3 5.1-27 NNM June 1979
NYSEtG ER NEW HAVEN-NUCLEAR Commercial landings were representative of the fish harvest rather than actual O fish population numbers. Impinged fish and equivalent adults ranged from 0.03 percent of the yellow perch landings to about 5 percent of the rainbow smelt landings. No significant impact of commercially important species is expected. In summary, the impact of intake operation on the major forage, commercial, and sport species will be negligible. The alevife vill be the dominant species impinged and entrained by a large margin. It is also the dominant forage species in Lake Ontario and intake impact vill affect a very small percentage of the population. The remaining species affected are primarily additional forage species in the lake. They are all of secondary importance to alevives and smelt as forage species. In the absence of standing stock estimates, little can be said about impact on populations of the species. A significant impact is unlikely in the loss of 259 emerald shiners to 15,453 threespine sticklebacks. The stickleback is the only one of these species estimated impinged in numbers greater than 1 percent of the estimated total. It is abundant near the shore at Fitzpatrick Station ( 5 and the population appears to be increasing '"o' indicating no adverse effects of impingement at Fit:Fatrick. Impact at the proposed station vill be about an order of magnitude less because the volume of water required is smaller. It was therefore concluded that impact on the numerically dominant species impinged and entrained, and on the major forage, sport and commercial species, vill be negligible. 5.1.3.2.3 Discharne SYste9 Effects The proposed plant discharge system, including structures, equipment, flows, and temperatures, is described in Section 3.4.4 Section 5.1.2 describes the physical characteristics of the plume. Under worst case conditions, which occur at a frequency of about 1 hr/10 yr, blowdown is expected to be diluted 10 times in 6 see and will encompass a volume of only 34.8 cu m. Under worst case heat dissipation conditions, within 16 sec, the discharge AT near the surface vill be only 1.6 C with a volume of 122 cu m. The location for the proposed plant discharge diffuser is at the 26-ft depth contour of Mexico Bay in the center of the study area (Transect III, l Figure 2.2-16), approximately 200-ft shoreward from the intake structure. The selected location was determined to be biologically acceptable based on findings of ecological studies conducted during 1977 (See Section 2.2.2). Rationale presented in Section 5.1.3.7.1 under Intake placement are generally applicable for selectica of the location for the diffuser. Because the diffuser vill be located away from the most biologically productive areas (10 and 20-ft depth contours and the vestern portion of the study area), no significant adverse effects are expected (see details in the following sections). bb a- O Amendment 3 5.1-28 June 1979

NYSE8G ER NEW HAVEN-NUCLEAR 5.2.5 Summary of Annual Radiation Doses The calculated annual radiation doses to the maximum individual from liquid and gaseous pathways are presented in Tables 5.2-16 through 5.2-24. As can be seen from these tables and Table 5.2-25, the calculated annual radiation doses are below the design objectives of 10CFR50 Appendix I for the site. The maximum calculated dose was 4.2E+00 mrem / year to an infant thyroid. It represents an infant who resides at a location of 0.5 mi or 805 m south of the facility who obtains all of his or her milk from a goat located 0.8 mi 1,290 m north-northwest (maximum farm location) of the facility. All other calculated doses from gaseous releases to the maximum individual assume a residence and vegetable garden at 805 m south and a farm (for milk and meat) at a location 1,290 m north-northwest. For the liquid releases, it was assumed the maximum individual obtains drinking water from the closest public water supply which is Oswego, located 11 m west or 17.7 km from the facility. The maximum individual was assumed to consume fish, invertebrates, and ducks cat'sht at the edge of the initial mixing zone. This location was also used in calculating doses from swimming and boating. Food products assumed to be irrigated were irrigated with water taken from the clcsest accessible shoreline. The calculated doses from shoreline recreation also were performed at this location. The calculated dose to the maximum individual from liquid pathways was 4.0 mrem / year to an infant thyroid. This dose was primarily a result of the consumption of goats milk. It was assumed the goat grazed on irrigated pasture for 6 month's of the year. The calculated annual doses for the population residing within a 50-mi radius of the site are presented in Table 5.2-25. For the liquid effluents, the calculated whole body and thyroid doses are 7.3E+00 and 9.5E+00 manrem/ year, l respectively. The calculated doses from gaseous pathways are 1.lE+00 manrem/ year whole body and 1.9E+00 manrem/ year thyroid. These doses were calculated for a projected population in the year 2010 of 1.2E+06 people within 50 mi of the site. The milk, meat, and vegetation 50-mi radius crop yield as well as the 50-mi radius sport and commercial fish harvest are presented in Appendix 5.2A. 5.2.6 References for Section 5.2

NYSEEG ER NEW HAVEN-MUCLEAR 6.2 NYSE4G'S PROPOSED OPERATIONAL MONITORING PROGRAMS 6.2.1 NonradioloRical Surveillance 6.2.1.1 Aquatic-Abiotic 6.2.1.1.1 Chemical Discharnes preoperational The water quality monitoring program described in Section 6.1.1.1.2 was designed to document overall background concentrations of water quality parameters in the aquatic environment of the site area. These data vill be supplemented by data generated during a 1 year preoperational study to be conducted approximately 2 years prior to the startup of Unit 1. It is anticipated that the area of both the intake and discharge structures will be monitorad. The study will be designed to document any significant changes in ambient conditions of important water quality parameters that may have occurred since the baseline study. Water quality parameters to be studied will be those that are of major importance to aquatic ecology for parameters to be monitored, sampling locations and frequencies (Section 6.2.1.2). Operational Table 6.2-1 provides applicable water quality standards and effluent limitations. Due to the anticipated minor water quality impact of the proposed facility, it is expected that operational effluent sampling will primarily involve in-plant monitoring, in addition to water quality sampling conducted in conjunction with the operational aquatic ecology sampling efforts. The final design of the operational water monitoring program will be delineated in the Environmental Report - Operating License Stage. 6.2.1.1.2 Thermal Measurements A thermal survey of the discharge plume is expected to be performed during the station's operational stage. The data obtained from this survey would be examined to ensure compliance with the :hermal criteria for New York State (Section 3.1.1). The scopt of this progrr. will be defined in the operating License stage of the Environmental .'57 ~ c.. In conjunction with the preoperational water quality monitoring program described in Section 6.2.1.1.1, ambient tamperature conditions are expected to be monitored in the area of the discharge structure. As is the case with the preoperational water quality monitoring progran, the thermal monitoring would be a 1 year study conducted approximately 2 years prior to the startup of Unit 1. 6.2.1.1.3 Erosion and Sedimentation The facility is located approximately 2 mi from the shore of Lake Ontario; no permanent structures will be located along the shoreline.

The para eters used to modo] the physical ground water regime are also presented in Section 2.4.2.1, Oper4tional ground water conditions are not expected to differ significantly from preoperational conditions. Ground water conditions enectatered during the construction stage will be documented and compared with original preoperational input. If differences exist, the impact on operational conditions will be evaluated and discussed in the Environmental Report - Operating License Stage. The equipment for monitoring ground Fate- conditions during operation will be a portion of that used for the preoperaticaal program. Several existing observation wells will be maintained and monitored during the construction stage. If necessary, additional wetis will be installed to assure that adequate water level monitoring locations exist between the site and the nearest down gradient users and/or surface water source. The operational ground water monitoring program will be described in detail in the Environmental Report - Operating License St&ge. Sections 6.1.5 and 6.2.2 discuss the operatienal nonitoring of ground water for radionuclides. 6.2.1.2 Aouatic Biota A preoperational monitoring prograS Wili ccamence approximately two years prior to startup of Unit 1. A map showing proposed sampling locations for the preoperational monitoring program is provided in Figure 6.1-6. The sampling locations will te on Transects I, III, and V of the baseline aquatic ecology study at the 10, 20, 30, and 40 ft depth contours, plus five shoreline locations. Table 6.2-2 provides the parameters to be collected, method of collection, sampling frequency, number of replicates, and the sampling locations and depths. Field laboratory and data analysis procedures sill bethe same as those used in the baseline aquatic ecology study. The water quality profiles for temperature, dissolved oxygen, and pH will follow the field procedures described in Section 6.1.1.1.2.3. Bottom gill net, bottom trawl, and seine gear descriptions and field procedures are presented in Section 6.1.1.2.8.2. Drift macrainvertebrate and ichthyoplankton will utulize the gear and field sampling procedures described in Section 6.1.1.2.9.2. Sample analyses procedures for drift macroinvertebrates, fish, and ichthyoplankton are presented in Sections 6.1.1.2.7.3, 6.1.1.2.8.3, and 6.1.1.2.9.3. respectively. However, no fish scale or stomach samples will be enllected or analyzed. Descriptions of data analyses have been provided for macroinvertebrates in Section 6.1.1.2.7.4, for fish in Section 6.1.1.2.8.5 and for ichthyoplankton in Section 6.1.1.2.9.4. Approximately one yaar prior to initiation of the preoperational study, the program will be reevaluated and - final details and modifications deemed necessary at that time will be proposed Amendment 1 6.2-2 5651-95 March 1979
NYSE8G LR NEW HAVEN-NUCLEAR 7.3 OTHER ACCIDENTS Oils, chemicals, and other materials are stored onsite in various areas. The accidental release of these to the environment could cause adverse effects. An evaluation of the effects of accidents which could cause such releases are included below. The probability of accidental releases from any source is minimi:ed by design of the storage and handling facilities, operator surveillance, and the attendance of personnel during operation. Table 7.3-1 shows the expected storage facilities for oils and hazardous chemicals at the station. Sections 3.6.3 and 3.6.4 describe the locations of storage facilities for oils and harardous chemicals at the station, and details of their containment drainage. The use of multiple storage tanks, building sumps, diked areas, and retention basins reduces the risks to the environment associated with storage of potentially hazardous materials. 7.3.1 011 and Gasoline Scills 011 vill be used in various equipment and stored in tanks both inside and outside the station buildings (Table 7.3-1). The storage tanks are located in diked areas constructed of concrete designed to contain the volume of the single largest tank in addition to the runoff resulting from the one in 10 yr, 24-hr storm, described in 3eccion 3.6.4 The area is designed to prevent the release of stored materials to the surrounding surface water or ground water due to leakage, spillage, or ruptures of tanks. Oil spilled or leaked inside buildings flows to appropriate sumps. Drainage is discharged following oil / vater separation as required to ecmply with -0CTR423. Totential spills or leakage from the auxiliary boiler fuel oil tank are contained within a diked area. Spills are recovered from the diked area and reclaimed or disposed of offsite by contractors :.icensed by the State of New York. Treated runoff from this area is discharged in compliance with *he limitations of 40CTR423. A 5,000-gal underground gasoline tank dispenses fuel to station vehicles during station operations using conventional service station pumps. Tuel unloading operations are attended by an operator who, in tre event of a spill, initiates corrective actions. Surface spills during vahicle fuel operations are contained at the point of spillage and manually cleaned up. Underground spills effect a small area and are cleaned up manually. Station and switchyard transformers are insulated and cooled by oil . Transformers are enclosed by dikes large enough to contain all the oil in the largest transformer in the diked area in addition to the runoff resulting from the once in 10-yr, 24-hr storm (Table 7.3-1).

All oil unloading operations are attended by an operator who, in the event of a spill, initiates oil containment, recovery, or cleanup operations. 7.3.2 Che-ical Spills Diked areas constructed of impermeable material and/or station buildings wi11 contain a spill if the chemicals stored in tanks onsite, both inside and outside the plant buildings, are released from their storage tanks (Table 7.3-1). Indoor storage is provided for sodium hydroxide, which is used for regeneration of demineralizer resins and in the containment spray system. Indoor storage is also provided for other chemicals such as ammonia and hydrazine, which are used for steam generator water treatment. Concrete in the vicinity of these tanks is covered by a corrocion resistant finish to prevent deterioration. Outside storage is provided for sodium hypochlorite and for sulfuric acid. Chemicals spilled inside the plant buildings flow to sumps where they are retained until pumped either to appropriate containers for disposal or to treatment facilities prior to discharge to ensure that no harmful substance is released to surface watercourses. Chemicals spilled outside the station buildings are contained within diked areas and are recovered or cleaned up manually. Chemical unloading operations are attended by an operator who initiates chemical containment, recovery, or cleanup operations in the event of a spill outside of the diked area. t e Amendment 3 7.3-2 SMW ,une 1979

NYSE1G EP. NEW HAVEN-NUCLEAR stay. Temporary accommodations include primarily hotels and motels, rental mobile homes, and rental apartments. Temporary or transient accommodations are not in large supply within several miles of the proposed station. Relative to more populated counties and areas that draw a substantial number of tourists, there are few hotel / motel accommodations in osvego County. Table 8.2-9 reflects the availability of hotel / motel rooms for construction workers under a " worst case" analysis, using peak summer occupancy rates reported by these f acilities' . Individual operators of lodges in the area suggest that the actual number of vacant rooms that would be available to station workforce vill be higher than peak rates indicate and it is thus assumed that average annual vacancy rates are more accurate. Individual operators voiced a preference for construction workers as customers due to the predictability and length ]f their stays. In addition, the few facilities currently open only during the summer months would be made available year round, given the increase in demand created by the influx of the station workforce'. Based on this information, the average annual vacancy rate for Oswego County is estimated at 25 percent higher than an assumed peak summer rate of 10 percent. Since most workers are likely to " double up" in the 190 available rooms based on an occupancy rate of 25 percent for 760 total rooms in Oswego County, 380 manual employees are expected to find hotel / motel accommodations in Oswego County at peak construction (Table 8.2-9). Doubling up is likely given that the average maximum occupancy (capacity) of area hotels / motels is estimated by local operators at 2.5 persons per room. Union officials have further indicated that this is a common practice for construction workers residing in transient accommodations. It is estimated that an additional 150 hotel / motel rooms, space for 300 workers, will be rented in northern Onondaga County, oneida County or southern Jefferson County due to individual preferences on price or location. The longer commuting distance from accommodations in these counties will tend to discourage some from locating there in favor of other accommodations in Oswego County. However, these 150 rooms are well within the 1.5 hr commute that is common practice for workforce temporarily committed to similar projects according to local labor union officials (Section 8.1.2.2.1). Manual workers who move into area transient accommodations will impact local housing by displacing other transients. As a result of year-round workforce inmigration, vacancy rates for hotel / motel accommodations, particularly for tourists in the peak summer months will be reduced. As Table 8.2-9 indicates, occupancy in Oswego County motels may run as high as 90-100 peccent in July and August. Assuming construction workers vill reside sa many of these accommodations for a period which includes this season, some tourists may be displaced into other areas (see Section 8.2.2.9 for further discussion of possible impacts upon tourism / recreation). Additional accommodations will be made available in rental mobile home parks. Those spaces already in place and available for oc cup ancy will be chosen first. An estimated 2,000 of the approximately 5,000 mobile homes in Oswego County are in trailer parks; others are assumed to be privately owned, and not available. Because mobile homes are generally more frequently used as permanent residences in Oswego County than elsewhere, the local proportion of 56E3M

NYSE8G ER NEW HAVEN-NUCLEAR units available for rental is assumed to be low. There is,however, a 5 to O 10 percent vacancy rate (i.e., available spaces) in mobile home parks. The rental units and vacant spaces in mobile home parks amount to about 10 percent of the total of mobile homes in parks, or about 200 homes. If workers double up in these accommodations there would be space for another 400 workers. Current trends indicate that mobile homes will be available primarily in southera Oswego county. The Town of West Monroe, for examplu, which borders Onondaga County, had 45 percent of its 1970 housing stock as mobile units. Mobile home rentals in Onondaga, Oneida, and Jefferson Counties will also be available. Assuming that construction workers are villing to commute the greater distance from mobile homes in these counties, an estimated 150 workers will be living in rental mobile homes in Onondaga County. Rental units in conventional housing vill also be available. Current data, as presented in Table 8.2-10, indicate about 80 vacant rental units in Oswego County and another 152 in the Syracuse ataa including northern Onondaga County. It is conservatively assumed that 50 percent of the available rental units, or 116, vill be rented to construction workers. if workers double up, these units vill provide acconmodations for 232 workers. Because construction workers are relatively well paid, and because some also receive a travel allowance, they will be able to bid fairly rigorously for the available supply of rental units. Given a limited supply of transient accommodations in Oswego County, however, it will be common for construction workers to often " double up" where capacities permit. As vacancy rates of all transient accommodations in the county are reduced, some inflation of rental prices may be expected. To the extent that demand for these accommodations in Oswego County is lessened by the availability of others, both within and outside the county, rates will remain ecmpetitive. Long term lease pricing for units near the site vill experience a moderate and rapid increase as station construction advances, enduring through the peak year of 1989. The construction of additional housing to accommodate temporary worker demand would be a further impact on the local housing stock. Speculative housing development and new construction of local motor lodges is a potential response to tight transient housing conditions in the site vicinity. Estimates of occupancy in existing accommodations - hotel / motel (680), rental apartment (232), and rental mobile home units (550) - identify accommodations for approximately 1,462 of the 1,741 manual workforce commuters. Of these workers, 860 are projected to locate in Oswego County, filling the minimum estimated capacity of existing transient accommodations there. The unmer demand represented by the remaining approximately 280 workers is likely to be filled in several ways. First, an increase in transient accommodation will occur as a result of expected population growth in the region between 1978 and the time of construction (Section 2.1.2). Development of new housing responding to demands of manual workers, as discussed above, may supplement this normal growth. Further, accommodations which housed construction workers Amendment 3 8.2-8
