Nine Mile Point Unit 2 ER-OLS CHAPTER 2 ENVIRONMENTAL DESCRIPTIONS

2.1 DESCRIPTION

OF THE STATION LOCATION The Nine Mile "Point site comprises approximately 364 ha (900 acres) on Great Lots 12 and 13, which are located on the south shore of Lake Ontario in the town of Scriba, Oswego

County, New York.

The land is owned by Niagara Mohawk Power Corporation (NMPC).

Figure 2.1-1 shows the general location of the site in relation to the surrounding 80-km (50-mi) area and shows parts of New York State, Lake Ontario, and Canada.

Figurc'.1-2 shows the surrounding 10-km (6.2-mi) area and the

- location of the site in relation to Oswego

County, New York.

Unit 2 shares the site with Nine Mile Point Unit 1.

Unit 2 occupies about 18 '

ha (45 acres) of the total site. 'he structures located onsite are principally owned by NMPC and include:

the Energy Information Center (owned jointly by NMPC and the Power A'uth'ority of the State of New York),

sewage treatment plants, security buildings, Nine Mile Point Units 1 and 2, and contractor buildings.

The Unit 2 natural-draft cooling tower is approximately 454 m

(-1,490 ft) southeast of the Unit 2 reactor centerline.

Other structures are associated with the transmission lines.

The James A. FitzPatrick Nuclear Power Plant, owned by the Power Authority of the Statef New York, is located on a

283.5-ha (700.5-acre) site immediate'ly east and adjacent to the Nine Mile Point site.

Centerline-to-centerline distance between Unit 2 and the FitzPatrick plant is about 716 m (2,3SO ft). 'etails of Unit 2 structures are shown on Figure 3.1-1.

There are no private residences or public facilities onsite.

The Energy Information

Center, however, is open to the public Tuesday through Sun'day, 10:00

Nine Mile Point Unit 2 ER-OLS Several studies have been conducted by investor-owned utilities, including a 1973 survey performed by Rochester Gas and Electric Company at the Sterling site, approximately 35 km (22 mi) west of Nine Mile Point'.

A comprehensive water quality investigation was conducted in the Mexico Bay area by New York State Electric and Gas Corporation during April 1977 to March 1978'.

NMPC and the Power Authority of the State of New York (PASNY) sponsored water quality surveys in the Nine Mile Point study area from 1973 through 1978

. Less extensive water quality monitoring reports were compiled in 1979 and 1980 by NMPC' The 1978 NMPC/PASNY survey provides the latest extensive data base and is used in this report for analysis of seasonal trends and for comparison with previous studies for long-term water quality trends'.3.3.3 Iake Ontario Water Quality Overview Lake Ontario has been designated by NYSDEC as Class A-Special Waters (International Boundary Waters),

6NYCRR702.1'.

Its waters are suitable for use as public water supplies, for culinary or food-processing

purposes, and for primary contact recreation.

In general, the water in Lake Ontario near Nine Mile Point has been found to'e of good

quality, with relatively low'utrient concentrations, low bacterial densities, and little industrial contamination.

Relatively high levels of dissolved

oxygen, more than adequate for most aquatic organisms, were found during all seasons.

The total dissolved solids (TDS) concentrations in Lake Ontario have increased since the early 1900s and are now above the New.York State Water Quality Standard'uality of the water in the Nine Mile Point study area was determined to be similar to the general water quality previously reported for the lake.

Spatial and temporal variations in water quality have been attributed to natural thermal stratification, action of wind and

storms, the Oswego River, west-to-east longshore currents, and hypolim-netic upwellings of cold, often nutrient.-rich waters'.3.3.4 Water Quality Parameters Monitored in Nine Mile Point Region Waters The 45 water'uality parameters measured in the Nine Mile Point site studies and reported in this section are listed in Table 2.3-12.

Parameters 1 through 17 were used to as-sess the general chemical quality of the water.

Parameters 18 through 24 are the major nutrients necessary for algal growth and are useful in identifying any potential influence Supplement 2

June 1983

Nine Mile Point Unit,2 ER-OLS from agricultural and sanitary waste discharges.

Parameters 25 through 31 are generally used to indicate contamination of waters by sanitary and industrial wastes.

Trace metals

analyses, parameters 32 through 45, provide a basis for the evaluation of toxicity impacts on aquatic life (Section 5.5) and were included to characterize

" ambient water quality relative to criteria based on toxicity to aquatic life.

The sampling locations, survey

designs, and analytical procedures utilized in the Nine Mile Point studies conducted for NMPC and PASNY are described in Section 6.6.

2.3.3.5-Water Quality in the Nine Mile Point Region of Lake Ontario Table 2.3-13 summarizes the water quality data for Lake On-tario in the vicinity of Nine Mile Point.

An 8-yr record of water quality is presented.

In addition to year-to-year trend description, data in Table 2.3-13 cover= historical high and low values for the Nine Mile Point region and yearly mean,

maximum, and minimum values for each sampling year.

Significant spatial water quality variability in Lake Ontario waters of the Nine Mile Point region was not evident in the raw transect

data, excepting solids and temperature.

Trends evident in important selected water quality parameter subsets are summarized in the following paragraphs.

Water Tem erature Water temperature influences the kinetics of chemical and biochemical reactions.

This parameter displays seasonal variations directly related to air temperature.

Water tem-perature was measured monthly or twice monthly in Lake On-tario in the water quality monitoring program.

In addition, continuous in situ monitoring was conducted.

Long-term trends indicate no significant change in water temperature over time Seasonal water temperature variations are illus-trated on Figure 2.3-14.

Spatial temperature variations are evident in the raw data presented in References 6 through 11 and 44 and 45.

The Nine Mile Point Unit 1 (Unit 1) discharge elevates lake sur-face temperature, particularly in the nearshore region.

The JAF plant has less of a temperature

effect, as evidenced by data taken from the water column in the vicinity of its dis-charge (Section 2.3.1.1.6).

Nine Mile Point Unit 2 ER-OLS CHAPTER 3 PLANT DESCRIPTION 3.1 EXTERNAL APPEARANCE AND PLANT LAYOUT 3.1.1 Description of the Project Unit 2

is located between Nine Mile Point Unit 1 (Unit 1) and the James A. FitzPatrick (JAF) plant.

The major station structures of Unit 2

are connected to the Unit 1 station structures by a passageway.

Unit 2 follows the basic visual character of Unit 1 through the use,of compatible color treatment and similar materials, including concrete and metal siding, The reactor building, natural-draft cooling tower, and main stack dominate the skyline.

The reactor building has a

drum-like cap sheathed in fluted metal siding that contrasts with the lower concrete portion.

The exposed surface of the lower portion of the reactor building, the cooling tower, and the stack are cast-in-place concrete that. is untextured and natural in color.

Tanks and open metal frame structures, such as transmission towers and switchyards, are protected with corrosion-resistant coatings.

Permanent station roads and parking areas are asphalt paved.

An existing railroad line extends to the Unit 2 reactor building and turbine building (Figure 3.1-1) to provide rail freight access.

The site is landscaped to blend with the surrounding natural topography, consistent with security requirements.

Land previously cleared and excavated during construction of ad-jacent power stations has been utilized during construction of Unit 2

for temporary office facilities, laydown area, switchyard and parking areas, thus minimizing the additional excavation around the station structures.

At the conclusion of construction activities, the majority of this

area, ex-cept for some office facilities and portions of parking areas, will be graded and seeded to promote the return of vegetative cover.

To control erosion in areas not planted with trees or shrubs, ground cover of either lawn or crushed stone is provided.

The Energy Information Center, located in the northwest por-tion of the

site, is a

contemporary stone and glass ranch-style structure used for public education and is a

tourist attraction.

Here, a three-part show is offered on

Nine Mile Point Unit 2 ER-OLS nuclear electric power, the growth of energy in upstate New York, the story of Niagara Mohawk Power Corporation (NMPC) and the Power Authority of the State of New York (PASNY),

and the operation of Unit 1.

This show includes a

working scale model of the plant and a nuclear fission display.

There are also energy exhibits, nature

trails, and picnic areas on the bluffs overlooking Lake Ontario.

Figure

3. 1-1 presents the station layout, including major structures, buildings, and important roads.

The baseline site topography, including baseline and proposed contours and landscaping around the structures, is shown on Figure 3.1-2.

Figure 3.1-3 shows the location and elevation of release points for gaseous wastes.

Figures 3.1-4 through 3.1-7 present ground-level photographs of the site from different locations.

Figure 3.1-8 shows an architectural rendering of the plant.

3.1.2 Ground-Level Photographs of Site To assess visual impact, visually sensitive and intensive land uses (e.g., residential concentrations, major transpor-tation

routes, state and local historic

sites, and re-creational attractions) within 10 km (6.2 mi) of Unit 2 were identified.

Properties listed in the National Register of Historic Places were identified within 16 km (10 mi) of the Unit 2 site.

Visually sensitive locations were visited in late October, when foliage density was lower than at other times of the year.

Sites surveyed for potential visual im-pact are identified and described in Table 3.1-1 and shown on Figure 3.1-9.

Surveys began with reconnaissance of all viewing locations.

Photographs were taken in the direction of Unit 2 at locations from which distant views were possible.

Where plant structures would be clearly visible within 10 km (6.2 mi),

plant perspectives, based on distance and direc-tion from photograph locations, were provided by computer and superimposed on the photographs.

These visual perspec-tives are presented on Figures 3.1-4 through 3.1-7.

As discussed in Section 2.2.1, Unit 2 is located in a region of predominantly rural residential, agricultural, and forest land uses.

The potential for visual impact of the plant is minimized by the remoteness of the site.

Vegetation and topography screen or block views of the plant at most visually sensitive areas.

In addition, since the industrial character of the area has already been established by Unit 1

and the JAF plant, the change in visual quality associated with Unit 2 is marginal.

Unit 2 will not, significantly im-3'-2
