OUESTIOfLAi2 Do you plan on continuing the use of these guttent techniques for reactor storage of spent fuel during the remaining time of your operating license or do you expect to change or modify them in some vay?

QE m Q1LAt). Which of the following techniques for at-reactor storage do you anticipate using until off-site spent fuel storage becomes available and how?

A. Re-racking of spent fuel.

B. Control rod epositiening.

C. Above ground dry storage.

D. Longer fuet burnup.

E. . her (p. .ase ' Jenti8y).

RESPONSE for A.2 and A.3 7.ica e new racks vill provide storage through the year 2005.

e OUESTION A.4.

Will the techniques described above be adequate for continued 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 plans?

RESPONSE for A.4 (For all 6 Stations)

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

QHEXIl0N A.i. Do you anticipate the need to acquire ad#itional land 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 - 4 sentences.)

RESPONSE for A.5 (For all 6 Stations)

No.

QUEST 1QILL.ft. Do you anticipate any dditional construction activity on-site, or imtediately adjacent to the power plant site, associated with the continued at-reactor storage of spent fuel for the operating lifetime of the plant, including a 20-year period of license renewal? (yes/no)

FESPONSE for A.6 (For all 6 Stttions)

-* Dry storage facility construction may be opted for Zion Station for spent fuel storage after the year 2006.

  • For remaining stations through the year 2011 -

UO

  • Beyond the year 2011 (for all r.tations) -- PROEABLY QUESTION Am2 If you answered yes en question 6, triefly describe this construction activity (e.g. expansion of fuel storage pool, building above ground dry storage facilities).

RESPONSE,for A.7 (For all 6 Stations)

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

  • Respor.ses to A'quatic Resource Questions LASALLE 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 operation of LaSalle County Station. Since January,1984 there have been a total of 45 violations of the Station's NPDES permit (through May, 1990), and no enforcement actions by EPA. Permit violation records prior to 1984 are not readily available but can be retrieved from the Company archives ,

if necessary. -

1 Question 3 ,

Since the issuance of LaSalle. County Station's Operating License in 1982, the NPDES permit was renewed twice (11/84 and 8/89).

The 1984 permit involved changes from the previous permit as a consequence.of_the initiation of plant discharges associated with station operation. 1he_ previous permit was written primarily to

-cover _ plant construction and start-up related discharges.

Changes in the 1989 permit generally concerned minor technical corrections-'to the wastewater discharge designations of some outfalls, and minor relaxation of some pollutant monitoring requirements because-of the station's good-compliance performance-

  • under the previous permit.,

Question 4-- )

L. 'No operational studies were required for this facility due to-the

[ use of a closed cycle cooling system and the location of the L intake and discharge, on a section of the Illinois River with L poor water quality. Five years (1974-1978) of construction- '

studies showed.the most abundant species were emerald shinner, l

gizzard shad and carp. The three species combined represented 82 l

to 94.7 % of the fish collected during-the 5 years. The l

differences that were noted in the abundance of fishes in the river from 1974 thru 1978 reflected natural variability in the fish populations _ associated with the river conditions.

1

LASALLE STATION Question 5 Entrainment and impingement studies were not required when the station began operation due to the design of the intake and the poor water quality in the Illinois River. Based on the predictive 312"b" submitted in November, 1976, the intake was approved.

Question 6 Nothing has happened to either enhance or degrade the biological resource near the site. However, tighter controls on and improved water treatment process by upstream dischargers, especially in the Chicago area has re;ulted in a gradual improvement of water quality. If it will continue to the point that the biological community will become more diverse remains to be seen. The improvement will be hindered by toxic bottom sediments that are resuspended in the water column by the constant barge traffic.

Even in a top quality stream the design of the LaSalle intake and discharge structure will prevent any significant detrimental affects to the environment.

Question 7 The Illinois River in the vicialty of the station has little recreational fishing but does have some boating although both activities are increasing as water cuality improves. There is no commercial fishing in the ar?a because the wate rJality is still poor. He have not identified any impacts on the b : of the Illinois River by others due to the operation of the LaSalle County Station.

Question 8 LaSalle County Station discharges effluents to the Illinois River. The Illinois River has a long history of environmental insults dating back to the 1800's, when flows in the Chicago River were reversed so untreated sewage should be discharged through the Illinois River system and away from Lake Michigan.

While significant recover of the river system has occurred, particularly over the last 10 years, numerous impacts on aquatic resources continue including: the existence of dozens of municipal sewage plant discharges; dozens of direct and indirect

LASALLE STATION Question 8 (continued) industrial discharges of process wastewaters; urban, rural and agricultural runoff; heavy barge shipping traffic; operation of locks and dams; the presence of toxics contaminated river sediments; and persistant dredging activities. Commonwealth Edison has not studied the cumulative impacts of these influences to enable one to accurately assess their relative contributions on water quality degradation.

Question 9 316"b" - Predictive study attached approved 12/29/79 316"a" - Not required because of closed cycle cooling system.

In answer to your June 28, 1990. request, attached is a summary listing the sonies paid to the various taxing districts as related to our nuclear stations.

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

As we discussed, the monies are attributed to the large tax parcels we identify a2.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 etnev.ated by the parcels on which the station buildings are located.

Additionall',, we have paid actually one-half of total amount lieted for 1989 taxes.

The remaining one-half will be paid by S6ptember 1, 1990.

w Responses to Aqu'atic Resource Questions LASALLE 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 operation of LaSalle_ County Station.- Since January,_1984 there have been a total of 45 violations of the Station's NPDES permit (through May, 1990), and no enforcement

. actions by EPAi _ Permit-violation records prior to 1984 are not readily available but can be retrieved from the Company crchives if necessary.

. Question 3 Since the issuance of LaSalle County Station's Operating License in 1982,-the NPDES permit -was ' renewed twice (11/84 and 8/89).

The-1984 permit involved changes froin the previous permit as a consequence of the initiat'.on of plant discharges associated with station operation. The previous permit was written primarily to cover plant construction and: start-up related discharges.

Changes in the 1989: permit. generally concerned minor technical corrections to the wastewater discharge designations of some outfalls, and minor relaxation of some pol.utant monitoring

. requirements.because of the itation's 9001 compilance performance-Lunder the previous permit.

. Question 4-No-operational'itudies were required f.or this facility due to the Mse of a ;Iosed cycle coeHng systte and the. location of the intake and discharge, en a section of tie Illinois River with

. poor water quality. five years (1974-lV78) 'cf constructioni studies showed the most abur. dant species were emerald shinner, gizzard shad and carp. The three species combined represented 82 to 94.7 % of.the fish collected during the_5 years. The differences'that were noted in the abundance of fishes in the river from 1974 thru 1978 reflected natural- variability .in the fish populations associated with the river conditions.

_g.

Questio.i 56 Entralnment and impingement studies were not required when the station began operation due to the design of the intake and the poor water quality in the Illinois P.tver. Based on the predictive 312"b" submitted in November,1976, the intake was approved.

Question 6 Nothing has happened to either enhance or degrade the biological resource near the site. However, tighter controls on and improved water treatment process by upstream dischargers, especially-in the Chicago area If har it resulted will continue in a gradual to the point improvement of water quality.

that the biological community will become more diverse remains to be seen. The improvement will be hindered by toxic bottom sediments that are resuspended in the water column by the constant barge traffic.

Even in a top quality stream the design of the LaSalle intake and discharge structure will prevent any significant detrimental affects to the environment.

Question 7 The Illinois River in the vicinity of the station has little rect eational fishing but,does hin some boating although both activities are increasing as wawr quality improves. There is no commercial fishing in the area because the water quality is still poor. He have not ioentified any impacts on the use of the Illinois River by others due to the operation of the LaSalle County Station. -

Question 8 LaSalle County Station discharges effluents to th- Illinois River. The Illinois River has a long history of environmental insults dating back to the 1800's, when flows in the Chicago River were revarsed so untreated sewage should be discharged through the Illinois River system and away from Lake Michigan.

While significant recover of the river system has occurred, particularly over the last 10 years, numerous impacts on aquatic resources continue including: the existence of dozens of municipal sewage plant disc.harges; dozens of direct and indirect

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

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

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 94 sumerous small tax parcels but the majority of monies (90%+) are generated by the parcels on which the station buildings are located.

Addicianally, we have paid Trenally one-half of total amount listed for 1989 taxes.

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

In answer to your June 28, 1990. request, attached is a summary itsting the monies paid to the various taxing districts as related to our nuclear stations.

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

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 st. Tion (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.

--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.
