  • Responses to Aquatic Resource Questions BYRON GENERATING STATION Question 1 There have been no modifications and or changes to the condenser cooling water intake or discharge system since issuance of the operating license.

Question 2 There exists no documentation of any adverse impacts on aquatic resources due to the operation of Byron Station. Since its Operating license was granted in February,1985 there have been a total of 78 violations of the Station's NPDES permit (through May, 1990), and no enforccment actions by EPA.

Question 3 Since the issuance of Byron Station's Operating License, the NPDES permit was renewed once in 1986. Currently the Illinois EPA is processing an application for another renewal of the permit. The 1986 permit involved substantial changes from the previous permit primarily related to the initiation of plant discharges associated with operation of the Station. The l

previous permit largely focused on construction and plant start-up related discharges. To a lesser extent, other changes to the 1986 permit resulted from EPA's incorporation of tighter discharge standards stemming from revised industry-wide and state l

water pollution control regulations.

Question 4 No operational studies were required by the regulatory agencies due to the station's use of a closed cycle tooline system (tower:). However the Illinois Department of Conservation was concerned that the heated discharge from the plant would increase the incidence of Aeromonal infection of catfish in the Rock River. Studies were conducted during the month of August beginning.in 1983 and are continuing. A copy of the report presenting the 1989 work is enclosed. This document provides some trend information for this study and the 1975 - 1979 construction study. Byron Unit Or e became operational in 1985 and Unit two in 1987.

k. ,. .

BYRON S1ATION Question 4 (continued)

The report indicates that the recent increase in the appearance of species indicative of relatively good water quality (small mouth bass, white sucker and other), the increated number of species collected during recent years and the decline in relative abundance of pollution tolerant species suggest that the water quality of the Rock River has improved since the construction phase studies.

The studies have shown no increase in 61romonat infections in catfish due to plant operation. He have an agreement with the Illinois Department of Conservation that we will limit our withdraw for makeup to 125 cfs. In addition net water consumption is limited to no more than 91 of the flow below 679 cfs.

Quastion 5 A predictive 31ti"b" was submitted to the Illinois EPA in 1977.

Although it was approved we were asked to conduct i g ingement studies when operation began to verify our predittions. A one year study was conducted in 1985-86 when Unit Cae began operation which showed a low impingement rate (annual estimate of 4,218) with a catch dominated by young of the year channel catfish.

IEPA then required a six-month study be conducted during winter months when both Units were operational. This study was conducted in 1987-88 and again showed low impingement rates (six months estimate of 6908 fish) composed primarily of young of the year channel catfish. Although more fish were impinged in 1987-89,.the average weight of fish declined greatly.

Question 6 No changes have occurred in habitat or water quality that resulted in the enhancement or the loss of biological resources.

The company has enhanced the fishery resource in the Rock River by stocking walleye from our fish hatchery into the River. This program began in 1985 as a research project to utilize extra walleye that we had produced. The program has proved successful and is being used to support proposals to stock other rivers by other organizations. The station is not impacting the improved walleye population.

Question 7 The Rock River which supplies the condenser cooling water for Byron Station i used extensively for recreational fishing and to a lesst.. degree boating. There is no commercial fishing allowed on the Rock River. He have not identified any impacts on the use of the Rock River by others due to the operation of the Byron Station.

. i Question 8 Byron Station discharges ef fluents to the Rock River at a location approximately 20 miles downrifer from the City of Rockford, Illinois. There are numerous impacts on the aquatic resources of the Rock River including the existence of municipal sewage plant discharges; urban, rural and agricultural runoff; dozens of direct and indirect discharges of industrial process wastewaters; hydroelectric and dam spillwrys; dredging activities; and widely fluctuating river discharge rates.

Commonwealth Edison has not studied the cummulative impacts of these factors to enable assessing their relative contributions on water quality degradation.

In answer to your June 28, 1990, request, attached is a summary listing l the monies paid to the various taxing districts as related to our nuclear stations. i The two years listed include 1985 taxes (paid in 1986) and our latest year, 1989 ,

taxes (payable in 1990). 3 As we discussed, the monies are attributed to the large tax parcels we identify as the " station" and we estimate this represents the majority of money we pay to the individual taxing districts. For instance, a station (including the cooling lake) may consist of numerous small tax parcels but the majority of monies (90%+) are generated by the parcels on which the station buildings are located, i Additionally, we have paid actually one-half of total amount listed for 1989 taxee. j The remaining'one-half will be paid by September 1, 1990.

7 QUESTION A.4 2

Will the techniques described above be adequate for continued o at-reactor storage of spent fuel for the operating lifetime of the plant, including a 20-year period of license renewal, or are you developing other planst EI110 NEE _191.Ad (Fer all 6 Stations)

Yes. Commonwealth Edison believes that rod consolidatien and/or above ground dry storage vill be adequate for the operating lifetime af the plants. Construction of new storage facilities, either at a particular plant site or an off-site location to receive r, pent fuel from one or from several plants, appears to be technically fo> sib.e but is likely to be very expensive for vet pools as compared to dry storage technologies.

QUEIIIDILad. Do you anticipate the need to acquire !!didil19nni_11u14 for the storage of spent-fuel for the operating lifetime of the plant, including a 20-year period of license renewal? If so, how much land? When would this acquisition occur? Where?

(If answer is "yes", 3 - e sentences.)

EEEERR$E for A.5 (For all 6 Stations)

No.

QUESTION A.f. Do you anticipate any gu11Lthngt1 construction activity on-site, or immediately adjacent to the pover plant site, associated with the contir.ued at-reactor storage of spent fuel for the operating lifetime of the plant, including a 00-year period of license renewal? (yes/no)

RESIDESE for A.6 (For all 6 Stations)

  • Dry storage facility construction may be opted for Zion Station for spent futi storage after the year 2006.
  • For remaining stations through the year 2011 -- NO
  • Beyond the year 2011 (for all statiens) -

PROBABLY QUESIJDIiLAal. If you answered yes to question 6, briefly describe this construction activity (e.g. txpansion of ftml storage pool, building above ground dry storage f acilitiesi .

RELEQFSE for A.7 (For a12 6 Stations)

Any construction activity would be related to facilities built in connection with above ground dry storage.

. Responses to Aquatic Resource Questions i

BYRON GENERATING STATION Question-1 There have been no mcdifications and or changes to the condenser a cooling water intake or discharge system since issuance.of the operating license. ,

Question 2 There exists no documentation of any adverse impacts on aquatic resources due to the operation of Byron Station. Since its-Operating license was granted in February. 1985 there have been a total of 78 violations of the Station's NPDES permit (through

- May, 1990), and no enforcement actions by EPA.

- Question 3 Since the issuance of Byron Station's Operating License, the  ;

NPDES permit was renewed once in 1986. Currently the Illinois EPA is processing an application for another renewal of the permit. The 1986 permit involved substantial changes from the previous permit primarily related to_the initiation of plant i discharges associated with operation of the Station. The previous. permit largely focused on construction and plant start-up related discharges. To a lesser extent, other changes to the 1986 permit resulted from EPA's incorporation of tighter discharge standards stemming from revised industry-wide and_ state ,

water pollution control regulations-.

-Question 4

-No operational studies were required by the regulatory agencies due-to the station's use of a closed cycle cooling system (towers). .However the Illinois Department of Conservation was concerned that the heated discharge from the plant would increase the incidence of Aeromonas infection of catfish in the Rock-Rtver. Studies were conducted during the month of August beginning in 1983 and are continuing. A ' copy of' the report'--

presenting the 1989 work is enclosed. This document provides some trend information for this study and the 1975 - 1979 construction study. Byron Unit One became operational in 1985-and Unit two in 1987.

1 BYRON STATION

' . Question 4 (continued)

The report indicates that the recent increase in the appearance of species indicative of relatively good water quality (small mouth bass, white sucker and other), the increased number of species collected during recent years and the decline in relative abundance of pollution tolerant species suggest that the water quality of the Rock River has improved since the construction phase studies.

The studies have shown no increase in Aeromonas infections in catfish due to plant operation._ He have an agreement with the Illinois Department of Conservation that we will limit our withdraw for makeup to 125 cfs. In addition net water consumption is limited to no more than 9% of the flow below 679 cfs.

Question 5 A predictive 316"b" was submitted to the Illinois EPA in 1977.

Although it was approved we were asked to conduct impingement studies when operation began to verify our predictions. A one year study was conducted in 1985-86 when Unit One began operation which showed a low impingement rate-(annual estimate.of 4.218) with a catch dominated by young of the year channel catfish.

IEPA then required a six-month study be conducted during winter

. months when both Units were operational. This study was conducted in.1987-88.and again showed low impingement rates (six months estimate of 6908 fish) composed prinarily of young of the year channel catfish. Although more fish were impinged in 1987-89, the average weight of fish declined greatly.

Question 6 No changes have occurred in habitat or water quality that resulted in the enhancement or the loss of biological resources.

The company. hat enhanced the fishery resource in the Rock River by. Stocking walleye from our fish hatchery into the River. This program began in 1985_as a research project to utilize extra walleye that we had produced. The program has proved successful and is being used.to support proposals to stock other rivers by other organizations. The station is not impacting the improved walleye population.

-Question 7 The Rock River which supplies the condenser cooling water for Byron Station is used extensively for recreational fishing and to a lesser degree boating. There is no commercial fishing allowed on the Rock River. We have not identified any impacts on the use of the Rott River by others due to the operation of the Byron Station.

Question 8

-Byron Station discharges effluents to the Rock River at a location approximately 20 miles downriver from the City of Rockford, Illinois. There are numerous impacts on the aquatic resources of the Rock River including the existence of municipal sewage plant discharges; urban, rural and agricultural runoff; dozens of dirtet and indirect discharges of industrial process wastewaters; hydroelectric and dam spillways; dredging activities; and widely fluctuating river discharge rates.

Commonwealth Edison has not studied the cummulative impacts of these f actors to enable asse, sing their relative contributiens on water quality degradation.

4 4 l In-answer to your June 28, 1990. request, attached is a summary listing the monies paid to the .various taxit.g districts as related to our nuclear stations.

- The two years listed include 1985 taxes (paid in 1986) and our latest year, 1989 tax <ss (payable in 1990).

As we discussed, the monies are attributed to the large fax parcels we

- identify as'the " station" and we estimate this represents the majority of money we pay;to the individual taxing districts.- For instance, a station (including the

- cooling lake) may consist of numerous ass 11 tax parcels but-the majority of monies (90%+) are generated by the parcels on which the station buildings are located. 4 Additionally, we have paid actually.one half of total amount listed for 1989 caxes.

The remaining one-half will be paid by September 1.-1990.

In answer to your June 28. 1990. request, attached is a summary listing

- the monies paid to .he various taxing dt tricts as related to our nuclear stations. 1 The two years listed include 1985 taxes '. paid in 1986) and our latest year, 1989 '

taxes (payable in 1990).

t As.we-discussed, the monies are attributed to the large tax parcels we identify as the " station" and we estimate this represents the majority of money we ,.

pay to the individual taxing districts. For instance.,a station (including the '

cooling lake) sayLconsist of numarous small tax parcels but the majority of monies (90%+) are generated by the parcels on which the station buildings are located.

Additionally, we have paid actually one-half of total amount listed for 1989 taxes.

The remaining one-half will:be paid by September 1, 1990.
