Braidwood ER-OLS Gseg estimates indicated the presence of relatively large numbers of

' fish at mid-stream above Transect 3. This mid-stream concentra tion of fish may have, in part, accounted for the low fish numbers encountered in the near-shore regions of the river.

Population estimates based on the total number of fish captured and recaptured were relatively low when compared with the total number of fish collected during the survey. Although the total number of fish marked and recaptured using this technique does not necessarily have to be large (Ricker 1958) , the obvious lack of sufficient numbers of marked and recaptured fish made the results less reliable.

2.2.1.11.4 Select Species Age, growth, food habits, parasites, and condition factors of rock bass, longear sunfish, smallmouth bass, largemouth bass, and white crappie from the Kankakee River and Horse Creek were studied in 1974. The growth rates of these fish varied f rom f air to good when compared with those of other fish populations described in literature. Also, except in the case of white crappie, they had relatively higher condition factors (see Table 2.2-49). Annual increments in length varied f rom year to year.

The majority of fish seemed to be growing well in 1974.

Select fish species of the Kankakee River and Horse Creek fed on r^

a wide assortment of aquatic invertebrates and, in several cases, on minnows and other fish (see Figures 2.2-24 through 2.2-27) .

(N) Aquatic invertebrates were available in the study area throughout the study period. Some invertebrate species were fed upon selectively. In several cases, the changing feeding habits of fish with the season was largely attributed to the seasonal fluctuation of the benthic community.

Fish collected from the Kankakee River and Horse Creek were subject to parasitic infections. The degree of infection varied among species. Parasitic effects were not severe, as indicated by the growth patterns and condition f actors (see Table 2.2-50) .

In several cases fish were shown to host more than one species of parasite at one time. The parasitic organisms encountered in the study area were mostly trematodes (flukes) .

2.2.1.11.5 Eqqs and Larvae Fish eggs are commonly classified as being buoyant, semi-buoyant, or demersal (on the bottom) (Ricker 1971) . The collection of eggs and larvae during the survey was done using surface and bottom plankton net tows and bottom pumping. These collection methods were used so that the three types of eggs would be represented in the sampling. Eggs collected by plankton nets are most likely buoyant or semi-buoyant, and those collected by bottom pumping are primarily demersal. A limiting or complicating factor in the assessment of fish eggs and larvae in any area is that eggs and larvae may be concentrated in spawning 2.2-19

Braidwood ER-OLS AMENDMENT 1 llh FEBRUARY 1983 AMENDMENT 5 DECEMBER 1983 areas rather than widely distributed. The collection of ade-quate numbers of demersal eggs using traditional collecting methods was dif ficult, and the movement of fish between dif fer-ent bodies of water (such as the Kankakee River and Horse Creek) made it almost impossible to define population boundar-les during breeding periods.

Fish eggs and larvae were collected during the first sampling period (May 2, 1974) at Transect 3, which indicates that spring spawning had already occurred by this time (see Table 2.2-51).

Larvae were collected at Transect 3 as late as June 27, 1974.

Thus, the spring spawning period started before May 2 and ex-tended beyond mid-June 1974. Larvae collected during the first part of the sampling probably belonged to early spring spawners, whereas eggs and larvae collected in the latter part of the survey were from early summer spawners.

It is known that different fish species have different tempera-tures that induce spawning. For example, the spawning tempera-tures for rock bass, longear sunfish, and smallmouth bass have been reported to be 200 to 210C, 240 to 300C, and 130 to 210C, respectively (Scott and Crossman 1973). It was, lll therefore, not unusual that fish eggs and larvae were collected throughout the sampling period.

Bottom plankton tows and bottom pumping produced a small number of eggs (15) and larvae (54); none were collected using surface plankton tows. The number of eggs and larvae collected per cubic meter of water at each sampling location is presented in Table 2.2-51. Although some larvae were collected at each transect, no eggs were obtained from Transects 2 and 5 during the entire sampling period (see Table 2.2-51).

More eggs and larvae were collected from Horse Creek (Transect

4) during May 1974 than at all the Kankakee River transects (Transects 2, 3 and 5) combined, which suggests that spawning was more intensive in Horse Creek in May 1974 than in the Kankakee River at this time. Conditions in Horse Creek appear to be more ecologically favorable for early spawning than the Kankakee River conditions. Horse Creek is shallow (mean depth of 4.6 feet), having relatively warm water (ranging between 2.80 and 24.20C during March through June) and low flow.

Fish movements between the creek and the river were suggested from the observations made during the 1974 through 1975 study.

Both the creek and some areas of the river appear to provide nursery grounds for eggs and larvae.

Braidwood ER-OLS each of these areas is quite distinct. The unmined areas are affected by past agricultural practices and soil types. The mined areas are affected by the acidity and texture of the surface material, slope, ridge heights, and the amount of time elasped since mining occurred. The type of reclamation practiced also af fects strip-mined areas.

The flora and fauna observed during the baseline survey and their interactions were summarized by indicating their relative positions within a generalized food web for the Braidwood site (see Figure 2. 2- 28) . This food web schematic considered the site as a whole without distinguishing between the various habitats sampled. It indicates general relationships between vegetation, herbivores, omnivores, insectivores, anf carnivores found on the site. Species grouped within boxes are ger.evally similar in food preference, but a broad range of nutrient options may be represented. Although human beings are not included, it should be recognized that they are not only an omnivore in the web, but that they also influence the web by their effects on the habitat of the individual species.

Initial ecological studies at the Braidwood site began in the fall of 1972 and continued on a seasonal basis during the winter, spring, and summer of 1973. The results and projections of the construction inpact concluded from these studies for the fall, winter, and spring surveys are included in Subsections 2. 7.1 and

- 4.1.5 of the Braidwood Station Environmental Report - Con-(3) struction Permit Stage (ER-CPS) . The impact was assessed in the ER-CPS and the Braidwood Final Environmental Statement (F ES) .

The summer 1973 survey confirmed the minimal environmental impact as described in both the ER-CPS and FES.

To augment the initial (1972 through 1973) baseline study, a program was designed for the 1974 through 1975 period. The results and conclusions presented in the 1974 through 1975 Final Terrestrial Monitoring Report further support the impact assessment presented in both the ER-CPS and the FES. The information obtained during these 2 years of baseline monitoring is summarized in the following subsections.

2.2.2.2 Obiectives of the 1972 through 1973 Baseline Survey The major objectives of the terrestrial baseline study (1972 through 1973) were as follows:

a. to record and describe "important" species of flora and f auna in the site area during all four seasons of the year;

b. to provide baseline data that could be used to develop a monitoring program for detecting impacts of plant construction and operation on the environment; l 2.2-21

c. to delineate the different types of habitats near the Braidwood site environs;

d. to determine the ecological relationships between the biotic and abiotic parameters present; and

e. To offer recommendations concerning effects of construction on any " unique or unusual" plants or animals found within zones of direct impact.

2.2.2.3 Objectives of the 1974 through 1975 Baseline Survey The six major study objectives of the terrestrial baseline study (1974 through 1975) were the following:

a. to document existir.y biota in recently purchased areas that were not evaluated during bLseline surveys;

b. to evaluate the biotic components of areas that will be subject to construction activity for sta-tion and switchyard facilities; g

c. to observe annual fluctuation in the biological density represented within the site;

d. to expand the biological data base for predicting impacts 9ssociated within the site; e, to provide background data for the initiation of a specific program to evaluate the impact of site development on migratory water fowl; and

f. to identify significant parameters to be measured or monitored in later studies to provide continu-ing estimates of real and potential impacts.

2.2.2.4 Summary of the 1972 through 1973 Baseline Survey The following results were based on the field baseline studies conducted from the fall of 1972 through the summer of 1973 in the environs of the Braidwood site.

The treatment plant is designed to handle a maximum of 15,000 gallons per day. The treated effluent is combined with the cooling pond blowdown and discharged to the Kankakee River. The effluent contains a residual of up to 1 mg/ liter free chlorine, and after mixing with the cooling pond blowdown, the residual chlorine content is negligiole. Water from onsite wells is used for the sanitary system during construction. During station operation, water from the Kankakee River will be used for the sanitary system.

The sewage treatment unit for permanent plant service operates as an extended aeration system for 553 operating persontic "'

2 approximately 25 gallons per person per day. The ef fluent from

(^ the unit is given tertiary treatment (consisting of filtration (s} and recirculation in a packaged unit) and then is chlorinated before discharge. During construction, factory-installed modifications allowed the package unit to operate as a contact stabilization system designed for 1,500 construction personnel at 15 gallons per person per day, or a total of 22,500 gallons for the 8-hour work day.

The environmental effect of the treated sewage is discussed in Section 4.1 and 5.5 3.7.2 Other Waste Systems The station maintains four diesel generators to provide emergency electrical power during a loss of offsite power. The station also has two diesel-driven auxiliary feedwater pumps, one miscellaneous equipment diesel, and one diesel-driven fire pump. These engines exhaust directly to the atmosphere through muffler systems. The use of these systems other than for routine testing is not anticipated during normal operation.

These diesels are tested by starting each one once a month and running it for one hour. 5 Two No. 2 fuel oil-fired auxiliary steam boilers, each rated at about 75 x 106 Btu, are used to supply steam for initial plant p

These boilers are supplied with low-sulfur distillate oil to meet Illinois state emission standards for control of gaseous sulfur dioxide emissions. When firing distillate oil, these standards limit S02 emission to 0.3 lb per million Btu heat input. In addition, the oil used has a low ash content so that the emission of particulate matter from the stack is within the Illinois state emission standard of 0.1 lb per million Btu heat input. The emission standard on the visual scale is 30% opacity, which is achieved when firing the low-ash distillate oil. Table 3.7-1 lists the state emission standards for the new distillate oil-fired units of less than 250 x 106 Btu. These are the only standards currently applicable to the auxiliary steam boilers.

During normal operation, one boiler is expected to operate an average of about 2 weeks per year at 80% capacity.

Trash from the plant is disposed of of fsite by an independent contractor. Laundry wastes and wastes from chemical laboratory drains are processed through the radwaste system, which is described in Section 3.5 Solid, nonradioactive chemical wastes are disposed of of fsite by an independent contractor.

> FEBRUARY 1983 AMENDMENT 2 JULY 1983 AMENDMENT 5 DECEMBER 1983 CHAPTER 4.0 - ENVIRONMENTAL EFFECTS OF SITE PREPARATION, STATION CONSTRUCTION, AND TRANSMISSION FACILITIES CONSTRUCTION 4.1 SITE PREPARATION AND PLANT CONSTRUCTION 4.1.1 Construction Schedule A Nuclear Regulatory Commission (NRC) construction permit for the Braidwood Nuclear Generating Station - Units 1 and 2 (Breidwood Station) was issued on December 31, 1975. An exten-sion to the construction license was issued November 15, 1982. 5 As of April 1, 1983, 51% of the estimated $3.1 billion project 1 2 cost had been expended. Completion dates for Units 1 and 2 have been set for October 1985 and October 1986, respectively.

The specific conditions for environmental protection attached to the contruction permits are listed in Section 4.5.

The effects of site preparation and construction activities on

land and water use are described in the following subsections.

(G 4.1.2 Land Use The Braidwood site consists of approximately 4454 acres with 1 the south portion containing the pond, dikes, etc., being 3898 acres and the 556 acre plant area which is north of the pond area and contains the principal plant facilties.

All the land within the pond area was considered to be dis-turbed by construction of Braidwood Station or was previously disturbed by strip mining. Prior to construction this area was 1 made up of 3004 acres of strip-mine spoil, 777 acres of agri-cultural land and 117 acres of woods. 5 The 556 acres of the plant area consisted of 436 acres of agri-cultural land and 120 acres of woods. During construction of the station facilities, approximately 256 acres of land was disturbed, 221 acres of which were agricultural land and 35 acres were woods. After construction is complete, the perman-ent facilities including the main plant buildings, switch yard, parking areas, roads, etc., will occupy approximately 125 acres, of which 90 acres was agricultural land and 35 acres was wooded. The remaining 131 acres which was construction dis-turbed agricultural land and the approximately 300 acres that were not disturbed will be either planted for wildlife habitat p

immediate area (Grundy, Kankakee, and Will counties) . "

Some land biota will be displaced from the Braidwood Station site into the surrounding area where selective competition will take place for already occupied niches.

New habitats attractive to aquatic biota such as frogs, turtles, and some water fowl will be formed. ,

The Braidwood Station site is served by both highway and rail transportation facilitics.

Interstate 55 is less than 2 miles west-northwest, and Illinois State Routes 53 and 129 are less than a mile northwest of the station. The Illinois Central Gulf Railroad, which runs parallel with and between Routes 53 and 129, is used to provide spur track access from the site to the main line.

The initial site preparation work has two stages. The first stage consists of stripping, excavatina, and backfilling the areas occupied by structures and roadways. The second consists of developing the site with all necessary facilities to support construction, wells, sanitary such as offices, railroad tracks, warehouses, facilities, and power lines. The actual station construction began while these activities were in progress.

To accommodate the construction force, an onsite parking area was constructed, and a sewage treatment facility was provided. After construction seeded. is completed, this parking area will be graded and _

Existing roads on the station site are used as much as possible Y '

f or construction activities. The only new roads are those within the construction area proper and a service road created for work on the river structures. A township roadway that entered Commonwealth Edison Company (CECO) property was closed with approval of the highway commissioner of Reed Township. The _

abandoned roadway has no public access or use and is completely controlled by CECO. No county, state, federal, or interstate highway has been rerouted as a result of Braidwood Station construction.

The designated construction areas, access ways, and laydown areas were cleared to permit construction of the permanent station --

I structures and facilities. In order to minimize erosion, a construction drainage system was incorporated into the site development plan.

Temporary gravel roads and permanent roads were installed with site grading and drainage facilities to permit all-weather use of the site for movement and storage of ,~

materials and equipment during construction.

• Areas only temporarily disturbed by construction were stabilized by native vegetation. In all instances, erosion control measures around the construction area were planned and scheduled as part of construction operation. To the extent possible, mechanical disturbances during the construction of any of the associated _

facilities were limited to the immediate construction site. In "

construction laydown areas, temporary diversions were constructed 4.1-2 n

(~; Braidwood ER-OLS AMENDMENT 1 Is- ) FEBRUARY 1983 AMENDMENT 5 DECEMBER 1983 4.3 RESOURCES COMMITTED The construction of the Braidwood Nuclear Generating Station -

Units 1 & 2 (Braidwood Station) involves permanent and tempor-ary uses of land, water and material resources. Tnis section describes the resources committed during plant construction.

4.3.1 Land Resources In the development of the 4454-acre site, 256 acres have been 1 affected by actual plant building activities including 35 acres of woods and 90 acres of agricultural land that will be changed from current land use during the life of the plant.

5 The pond area is approximately 3898 acres and has af fected 777 acres of agricultural land, 117 acres of woods and 3004 acres 1

of strip-mine spoil. Approximately 300 acres of the site was not affectad by site construction. The expected impact of site construction is described in Section 4.1.

The construction of permanent facilities on the site eliminates

(^J x_ some wildlife habitat, which results in shifts of wildlife pop-ulations to other areas. Those portions of the site not occu-pied by the permanent facilities or landscaped for aesthetic purposes will be allowed to return to a natural state.

There are some unavoidable animal deaths due to construction activities (e.g., the coverage of nests and dens), particularly in the cooling pond area. During pond filling, small mammals living on the pond site and not able to relocate to a safe area will be lost. Once the filling is completed, however, the pond will provide hnbitat for both nesting and migrating waterfowl.

The land that will be traversed by the transmission lines for the Braidwood Station is mainly farmland. Except for areas occupied by the tower foundations, there will be no commitment of farmland resources during the proposed period of transmis-sion line use. Any farmland disturbed by construction activi-ties will be restored.

4.3.2 Water Resources No permanent effect on water resources is expected at the Braidwood Station. The construction of the river intake and discharge structures will permanently alter ap; 'oximately 250 feet of shoreline on the southern bank of the Kankakee River.

r~ No other permanent aquatic disruptions are expected during the

Braidwood ER-OLS 4.3.3 Materials Used llhr ,

The materials used for the Braidwood Station are of two types:

those used for the construction of buildings; and fuel.

Construction materials include structural and reinforcing steel, portland cement, electrical cables, paints, coverings, and fixtures. Although these will be permanently committed during the lif etime of the plant, some of them can be at least partially reclaimed if the plant is eventually dismantled. The highly contaminated items will not be reusable. The discussion of fuel consumption and of other resources committed during plant operation is included in Section 5.7. The decommissioning and dismantling of the plant is described in Section 5.8.

~ Resource commitments due to operation of the.Braidwooo Nuclear Generating Station --Units 1 & 2 (Braidwood Station) fall into two categories: . resources committed during the active lifetime of the plant _and resources' consumed (i.e., committed irretriev-ably) during plant operation. . Resources ccamitted during plant construction are described in Section 4.3.

5.7.1 Resources Committed During Plant Lifetime Section 7.2 describes the present ecological characteristics of the Braidwood Station site area.- The expected impact of plant construction on the-surrounding ecological. community is des-cribed.in Section 4.1. The expected ecological impact due to plant operation is presented in'this section. Although changes in the local terrestrial ecology attributable to the presence of Braidwood Station could~be interpreted as being commitmen.ts of resources, a distinction should-be made between such conse-

. quences as the displacement of animal populations _and the des-truction of animal habitats; i.e. , natural vegetation. Plant operation should not reduce further the_ wildlife habitat al-

-tered by plant construction and, therefore, should not displace any-more animal populations. . Ecological monitoring will iden-tify and document changes' in the quantity .and quality of the chemical _and thermal. discharges and the resultant effects on the biotic community in the Kankakee River (see Section 6.2).

Resources committed during plant life cannot reasonably be considered as irretrievable long-term net losses. Preconstruc-tion surveys (see Section 2.2) indicated that there are no known threatened or endangered species of plants or animals

-indigenous to the Braidwood Station area. Since no undue or extreme environmental disturbance is expected to result from plant-operation, it is anticipated that natural flora and fauna could reestablish themselves after the plant is decommissioned if the area is allowed to revert to a natural state,

. The- use of land for the Braidwood Station is also a resource l

commitment. Subsection 4.3.1 describes the land that is re-moved from natural ano agricultural' production by plant' con-struction.- During plant operation, 4454 acres will be occupied 2 by plant facilities, the-cooling pond, and the exclusion area.

The cooling pond provides a habitat for waterfowl, shore birds,

The 1213 acres of land that will be unavail-able to agriculture represents about 0.1% of the total agricul-tural land in Will, Grundy, and Kankakee Counties. About one- 5 fourth of the land could be reclaimed af ter the plant is decommissioned without removal of any facilities.

Makeup water is expected to be withdrawn from the Kankakee River at an average annual rate of 90.8 cfs (see Table 3.3-1).

An additional 9.3 cfs of rainfall will be added to the Braidwood pond (see Tabic 3.3-1). An average of 56.6 cfs of water is expected to be lost through evapcration and seepage from tne cooling pond. Although most of this water is eventu-dily returned to the earth as precipitation, it is an immediate loss to the local area. In addition, an annual average blow-down of 43.2 cfs is eventually returned to the Kankakee River (see Table 3.3-1).

5.7.2 Irretrievable commitments of Resources The environmental effects of uranium mining and milling, the O

production of uranium hexafluoride, isotopic enrichment, fuel fabrication, reprocessing of irradiated fuel, transportation of radioactive materials, and management of low-level and high-level wastes are within the scope of the NRC report entitled

" Environmental Survey of the Uranium Fuel Cycle" (see Table 5.7-1).

The operation of the Braidwood Station will involve the con-sumption of a certain amount of uranium ore that represents a fraction of the current reserves and resources of the United States. The radioactive materials inventory appears in Section 3.8. During the expected lifetime of the plant, the estimated annual use will be 64,450 pounds of UO2 or 56,810 pounds of U.

6. 2. 2 - Terrestrial Monitoring. Program A terrestrial monitoring program designed to detect any effects of pond filling was submitted to 'the NRC staff in July,1978.

Staff approval was received in August, 1979 and the program was

. initiated in 1979 and has been continued through 1983. A

. description of the program is contained in Section 6.1.4.3.3 and a summary of the conclusions for the. years 1979 through 1982 is contained in Section 4.1.4.1.1. No off-site effects have been observed that could be attributable either to the 5 filling of the pond or to the presence of the pond. Since the operation-phase effects of Braidwood Station were focused on the filling of the cooling pond, and the present monitoring program indicates that there are no discernable effects of this action, it is proposed that the program be terminated and no

' operation-phase terrestrial monitoring program is required.

\~' FEBRUARY 1983 AMENDHEMT 5 DECEMBER 1983 CHAPTER 8.0 - ECONOMIC AND SOCIAL EFFECTS OF STATION OPERATION The Braidwood Nuclear Generating Station - Units 1 & 2 (Braidwood Station) will create a total of 553 permanent new jobs at the station site and an estimated annual payroll of 1

$14.6 million (in 1982 collars) when the station goes commer-cial in 1986.

The total agricultural land affected by the construction and operation of the Braidwood Station is 1213 acres. The con-struction of the cooling pond required the oiversion of 777 acres of agricultural land. About 77% of the remaining area 5 required for pond construction, or 3004 acres, consisted of strip-mine spoil. The total affected agricultural land (1213 acres) is about 0.1% of the total agricultural land in the three-county agricultural region formeo by Grundy, Kankakee,

-and Will Counties (see Section 4.1).

Permanent new residents attracted as a result of the Braidwcod Station project will be dispersed throughout the surrounding

' (A ') communities (see Section 8.4), so that there will be little effect on local services. The increased tax revenue attribut-able to the Braidwood Station project from property taxes is estimated to be $9.3 million in 1986 (see Section 8.2). Local 1 taxing districts should receive more tax dollars than required to provide the additional services for the new residents.

It is not possible to determine the benefit to the local econ-omy from the purchase of local goods and services for operation of the station. The average 1983 budget for contract payments for Commonwealth Edison's three operating nuclear stations, each with two operable units, is $17.3 million. These costs y include refueling, maintenance and waste disposal. The pro-curement of materials and services is based on a competetive bid system, and therefore no' estimate can be made as to which suppliers will provide the materials and service, the corres-ponding monetary value, or the county in which the supplier is located.

There are no historical sites located on the Braidwood site.

AMENDMENT 5 DECEMBER 1983

_UESTION Q E290.8 U Chapter five does not-address' environmental effects of station operation on land use and terrestrial ecology. . Please provide a current evaluation.

RESPONSE

The primary environmental effects of station operation on land use and terrestrial ecology. occurred at the time of construc-tion of the station and the construction and the filling of the

' cooling pond.

These effects were conversion of land use from strip mine spoil and farmland to station facilities and cooling pond. The prin-cipal effects on terrestrial ecology were conversion of terres-

. trial habitat to aquatic habitat and consequent dislocation of resident terrestrial. populations. As the area from the pond to

.the site perimeter has been revegetated, this land is providing r^c habitat.for~ terrestrial species. Additional habitat will be T) s available as the interior dikes and islands reyegetate and other areas disturbed by construction are-revegetated. Approx-imately 1792 acres are available for wildlife habitat (total site acreage of 4454 minus water surface area of.2537 acres and 125 acres containing plant facilities). Of the 3241 acres of land available for wildlife habitat before construction, 237 i acres were woodlands and 3004 acres were strip mined areas consisting mostly of ponds and bare spoil banks. In addition, there were 1213 acres of farmland, portions of which were fal-low at. times.

Before-construction there were 796 acres of prime farmland on this site. During. construction, 688 of these acres were dis- 5 turbed, 652 of which were permanently disturbed. There are now

, 144 acres-that are prime farmland, none of which will be cul-tivated for the life of the station.

Table QE290.8-1 provides a breakdown of the site land use allocations for the construction permit, preconstruction; and operational stages.

JSection 5.7.1 states that the 1213 acres of agricultural land

- that was' removed from production represents about 0.1% of the farmland in Will,.Grundy, and Kankakee Counties. About one-fourth of this agricultural land could be put back into

The results of the 1979 to 1982 terrestrial monitoring program which are summarized in Section 4.1.4.1.1 of the ER supports the current evaluation that no terrestrial ecological effects have occurred outside the station bounoary and none are ex-pected to occur.

Section 5.1.4 contains a discussion of the increase in humidity within a few hundred meters of the shoreline of the cooling pond and the potential for the occurrence of additional fogging and icing on the surrounding area.

-ORAL QUESTION Are there sufficient numbers of migratory waterfowl using the Kankakee River in the areas of the transmission line crossing and the river intake-discharge structures to constitute a con-cern?

RESPONSE

The Kankakee River, in the areas of the transmission line and the intake-discharge structures is not heavily used by migra-tory-waterfowl due to the strong currents and the rocky-gravelly substrates. There should be no reason for concern for any effects on migratory waterfowl.
