o Will the techniques described above be adequate for continusd QUK1IION Ae4 at-reactor storage of spent fuel for the operating lifetime including a 20-year period of license renewal, of the plant, or are you developing other planst EESPONSE for A.4 (Tor all 6 Stations)

Commonwealth Edison believes that rod consolidation and/or Yes.

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 wet pools as compared to dry storage technologies.

Do you anticipate the need to acquire additional land for the OUESTION A.S.

Beginning in the summer of 1977 a modified closed cycle mode of The daily adjusted variable operation was put into operation.

blowdown consisted of adjusting the blowdown rate between 111 and 115 cfs on a daily basis. Starting in June 1981, the operation was again modified during the summer months (June 15th through September 30th to operate in indirect open cycle. Under this operation, the cooling water from the plant would pass through the closed cycle system (spray canals and cooling pond) then be Aquatic monitoring and plume discharged into the Illincts River.

Question 2 There exists no documentation of any adverse impacts on aquatic rescuYces due to operation of Dresden Station.

available but can be retrieved from the Company archives if necessary.

Question 3 Since the issuance of Dresden Station's Operating license, the NPDES permit was renewed or significantly modified on ten occasions. None of the permit revisions were precipitated by new concerns over water quality impacts. Rather two permit revisions / renewals (in 1976 and 1979) primarily involved incorporation $f tighter federal effluent standards for the industry whict prompted construction of onsite miscellaneous wastewater treatment systems that additionally required licensing To a lesser extent some changes to the under the NPOES permit.

permit involved the relaxation of certain operating requirements such as the October,1980 permit modif t:ation allowing limited operation of the cooling pond with indirect open cycle discharges during the sumer months. Another, in July, 1987, relieved the Company of the requirement to perform instream thermal monitoring during summer months when the cooling pond 1$ operated with l-indirect open cycle cooling. The balance of permit changes 1976-88 concerned mostly insignificant scattered over the years technical corrections and clarifications to the wording of permit conditions and outfall descriptions.

service. Unit 2 went into service in August 1980 followed by Unit 3 in November,1971. He began our aquatic sampilng program in 1971 and it has continued through the present.

Enclosed is a copy of the 1990 report entitled "r.nal Report Dresden Station Aquatic Honitorirg, 1989" The report discusses historical changes and includes summary tables.

The most pronounced change is the higher number of fish species currently present in the area. The mean number of species is is 301 higher in the 80's than in the 70's, However in the 80's the total number of species have remsined essentially unchanged.

Throughout the study year', ginard shad, emerald shiner, green sunfish, carp and smallmouth bass have been among the most common A total of 93 fish species, has been species in the collection.

reported from the river studies near Dresden Station including three species recently listed as endangered (pallid chub, greater redhorse) and threatened ( river redhorse).

Question 5 A 316"b" demonstration was submitted in February 1977 and included impingement results (December 75 - December 76) and This demonstration, entrainment results (April - August, 76).

which is attached, was not approved by the USEPA.

They responded in December 1977 with a requirement for Edison to build a new intake structure. He then had to provide documentation (new studies) to prove our contention that the majority of the fish impinged came f.om our cooling pond and that the pond acted as a nursery contributing eggs, larvar and juveniles, back to the river. We were able to provide enough evidence to reverse the The end result of this process and obtaining decision.

permission to operate in indirect open-cycle mode during the summer was additional impingement studies, from 1977 - 1978 and 1981 - 1986.

In 1987 we were able to obtain permission to drop

, impingement sampling due to no adverse impact. The impingement studies are discussed in the attached 1987 report " Final Report Dresden Station Aquatic Monitoring 1986". The impingement These section begins on page 145 and ends on 182 of that report.

1) studies were conducted under two different modes of operation variable blowdown (77-78) and 2) indirect open, cycle (81-86).

The higher numbers impinged under variable blowdown reflect the contribution of fish from the cooling pond.

DRESDEN Question 6 Nothing has happenea to either enhance or degrade the biological resource near the site.

Improvements in water quality related to tighter controls on and improved water treatment processes by dischargers upstream in the DesPlaines River System may not result in greatly changed fish population for Dresden. One reason relates to the toxic sediments that are resuspended during the constant barge traffic. Another reason relates to the siting of the station at the confluence of the degraded Des Plaines River and the much higher quality Kankakee River to form the Illinois River. The water that enters the intake is a varying mixture of the two rivers and the discharge is into the Illinois River.

The station's intake and discharge are in areas that are influenced greatly by Kankakee River water. Our impart assessments already are concerned with a fish community that comes from a good quality stream as well as the fish populations from the Des Plaines.

Question 7 The Illinois River in the vicinity of the station has very little recreational fishing but does have some boating although both activities are increasing as water quality improves.

Ther, is no commercial fishing in the area because the water quality is still He have not identified any impacts on the use of thi poor.

Illinois River by others due to the operation of the Dresden Station.

Question 8 Dresden 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 R'.ver were reversed so untreated sewage should be dischstged 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 1:aatic resources ccntinue including: the existence of dozens of municipal sewage plant discharges; dozens of direct and indirect industrial discharges of process wastewaters; urban, rural and agricultural runoff; heavy large shipping traffic; operation of locks and dams; the presence of toxics in 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.

.?i In answer to your. June 28. 1990, request, attached is 4. summary listing the montes paid to the various taxine, districts as related to our nuclear stations.

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

As we discussed, the monies are attributed to the 1.*;ie tax parcels we identify as the " station" and wi estimate this represents the hajority uf money we pay to' the individual taxing districts.

For instance, a station (including the coo 11ng take) may consist of numerous esa11 tax parcels but the majority of monies (90%+) are generated by the. parcels on which the station build: w s 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.

Commonwealth Edison Dresden Station Units 2 and 3 NRC Docket Nos. 50-237/249 i

q :.

Responses to Aquatic Resource Questions DRESDEN GENERATING STATION Question i Units 2 and 3 at Dresden were designed to be operated open cycle for the condenser cooling water system. Because of changes in environmental laws and regulations - the cooling system was modified to closed cycle utilizing a cooling pond and spray canals.

The station began operating in this mode in 1974.

Beginning in the summer of 1977 a modified closed cycle mcde of operation was put into operation.

The daily adjusted variable blowdown consisted of adjusting the blowdown rate between 111 and ll5-cfs on a daily basis.

Starting in June 1981, the operation was again modified during the-sunner months (hne ISth through

. September 30th to operats in indirect open cycle. Under.this operation, the cooling water from the plant would pass through the closed cycle system (spray canals and cooling pond) then be discharged:into the Illinois River.

Aquatic monitorteg and plume survey were employed to support the efficiency of this mode of operation. Unit I was operated open cycis for the life of the unit.

Question 2 There exists no documentation of any adverse impacts on aquatic resourc_es due to operation of Dresden Station.

Since January, 1984 there have been a total of 44 violations of the Station's NPDES permit _(through May, 1990), and no enforcement actions by EPA.

P6 mit violation records prior to 1984 are not readily available but can be retr 16ved from _the Company archives if necessary.

Question 3 Since the issuance of Dresden Station's Operating li m e, the NPDES permit was renewed or significantly modified on un.

occasions. None of the permit _ revisions were precipitated by new concerns over water quality bpacts. Rathor two permit revisions / renewals (in 1976 and'1979) primarily involved incorporation of tighter federal effiuent standards for the industry which prompted construction of onsite utiscellaneous wastewater treatment-systems that additionally required licensing under the NPDES permit.

To a lesser extent some changes to the permit involved the relaxation of certain' operating requirements such as the October,1980 permit modification allowing limited operation of the cooling pond with indirect open cycle discharges during the summer months. Another, in July, 1987, relieved the Company of the requirement to perform instream thermal conitoring during Summer months when the cooling pond is operated with it# direct open cycle cooling.

The balance of permit-changes scattered over the years 1976-88 concerned mostly insignificant technical corrections and clarifications to the wording of permit conditions and outfall-des _criptions.

Question 4 Dresdon Unit 1 operated from August, 1960 until October 1978 when it was tt b n out of service for decontamination and back

fitting, lhe Unit was retired without ever returning to service. Unit 2 went into service in August 1980 followed by Unit 3 i.. November, 1971. He began our aquatic sampling program in 1971 and it has contir:ued through the present.

Enclosed is a copy of the 1990 report entitled " Final Report Dresden Station Aquatic Monitoring, 1989" The report discusses historical changes and includes summary tables.

The most pronounced change is the highee number of fish species currently present in the area. The mean number of species is is 301, higher in the 80's than in the 70's.

However in the 80's the total number of species have remained essentially unchanged.

Throughout the study years gizzard shad, emerald shiner, green sunfish, carp and smallmouth bass have been among the most common species in the collection. A total of 93 fish species, has been reported from the river studies near Dresden Station including three species recently listed as endangered (pallid chub, greater redhorse) and threatened ( river redhorse).

Question 5 A 316"b" demonstration was submitted in February 1977 and included impingement results (December 75 - December 76) and entrainment results (April - August, 76).

This demonstration, which is attached, was not approved b,y the USEPA. They responded in December 1977 with a requirement for Edison to build a new intake structure. He then had to provide documentation (new studies) to prove our contention that the majority of the fish impinged came from our cooling ponci and that the pond acted as a nursery contributing eggs, larvae and juveniles, back to the river. He were able to provide enough evidence to reverse the decision. The end result of this process and obtaining permission to operate in indirect open-cycle mode during the summer was additional impingement studies, from 1977 - 1978 and 1981 - 1986. In 1987 we were able to obtain permission to drop impingement sampling due to no adverse impact. The impitigement studies are discussed in the attached 1987 report " Final Report Dresden Station Aquatic Monitoring 1986".

The impingement section begins on page 145 and ends on 182 of that report. These studies were conducted under two different modes of operation 1) variable blowdown (77-78) and 2) indirect open cycle (81-86).

The higher numbers impinged under variable blowdown reflect the contribution of fish from the cooling pond.

' testion 6 Nothing has happened to either enhance or degrade the biological resource near the site.

Improvements in water quality related to tighter controls on and improved water treatment processes by dischargers upst eam in the DesPlaines River System may not result in greatly changed fish population for Dresden. One reason relates to the toxic sediments that are resuspended dui n.g the constant barge traffic. Another reason relates to the siting of the station at the confluence of the degraded Des Plaines River and the much higher quality Kankakee River to form the Illinois River. The water that enters the intake is a varying mixture of the two rivers and the discharge is into the Illinois River. The station's intake and discharge are in areas that are influenced greatly by Kankakee River water. Our impact assessments already are concerned with a fish community that comes from a good quality stream as well as the fish population; from the Des Plaines.

Question 7 The Illinois River in the vicinity of the station has very little recreational fishing but does have some boating although both activities are increasing as water quality improves. There is no commercial fishing in the area because the water quality is still poor. He have not identified any impacts on the use of the Illinois River by others due to the cperation of the Dresden

Station, p

Question 8 Dresden Station discharges effluents to tne 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 industrial discharges of crocess wastewaters; urban, rural and agricultural runoff; hea'vy large shipping traffic; operation of locks and dams; the presence of toxics in contaminated river sediments; and persistant dredging activities. Commonwealth Edison has not studied the Cumulative imoacts of these influences to enable one to accurately assess their relative contributions on water quality degradation.

1 QUESTION A.4.c 'Will tl.e 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 all16 Stations)

Yes. Commonwealth Edison believes thet rod consolidation and/or above ground dry storage will 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 wet pools as compared to dry storage technologies.

OUESTION A.E.

Do you anticipate the need to acquire additional la.nd 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.

OUESTION A.6.

Do you_ anticipate any additional construction activity-on-site, or immediately 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) cRSSPONSE for A.6.(For all 6 Stations)

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 NO Beyond the year 2011 (for all stations) -- -PROBABLY OUESTION A.7.

If you answerod'yes to question.6,.briefly. describe this construction activity (e.g. expansion of fuel storage pool,

- building above ground dry storage facilities).

RESPONSE f'r A.? (For all 6 Stations) o Any construction activity would be related to facilities built in connection with above ground dry storage.

J s,

't In answer to your June 28, 1990, request 4 attached is a summary listing the monies paid to the various taxing districts as related to our nuclest stations.

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

As we discussed, the monies are attribsted to the large tax parr:1s 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 numernus 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-balf vill be paid by September 1,1990.
