! MVIRONMENTAL STATLHIRI_BEV1EH SVffi&RY In support of the request to extend the duration of Quad Cities ,
Station Units I and 2 operating licenses, the final Environmental Statement '
(FES) dated September, 1972, has been reviewed for significant changes to the Station and the environs that may effect the findings included in the FES. ,
As originally designed, the Station utilizes Mississippi River water g for condenser cooling In an open cycle mode of operation. Condenser cooling t water was warmed a maximum of 23'r and discharged back to the river through a
! diffuser pipe system at a maximum rate of 2270 cubic feet per second (CFS).
- Concern over the possible adverse effects of once-through cooling on the l- river's biota resulted in a suit by a group of intervenors requiring closed- '
cycle cooling. In response to :he sult, a cooling canal was constructed around the Station's perimeter for recycling of condenser cooling water. The canal was equipped with 328 spray modules to increase the cooling capacity of the canal. Concurrent with the operational history of Quad Cities, extensive biological monitoring of the river's ecosystem was conducted each year. The ,
studies were used to aid in determining the impacts, if any, that Station operation had on the various aquatic communttles inhab' ting Pool 14. Results of these comprehensive studies had rot shown any measurable adverse effects of Station operation on the river's aquatic communities using either closed-cycle or open-cycle operation.
In consideration of these biological findings, Commonwealth Edison petitioned the governing regulatory agencies and intervenors to allow Quad Cities Station to return to open-cycle cooling. Following a thorough review i of the biological data presented, a new agreement was reached between the utilities and the intervenors to allow the Station to return to once-through cooling operation. 1his agreement was contingent upon continued biological c monitoring of the river's fish community. Subsequently, a revised National Pollutant Discharge Elimination System (NPDES) permit was issued on ,
December 23, 1983, which permitted open-cycle cooling for Quad Cities Station.
Modifications to the station have resulted in improvements in station operation and a lessened impact on the environment. The radwaste maximum recycle operation has resulted in considerably lower gaseous and liquid waste discharges. _The chlorine injected into the once-through cooling water system
- has been reduced by over 50%. This reduction was a result of utilizing sodium L bromide as a chlorine enhancer. The use of sodium bromide increases the L effectiveness of the biocide and has been shown to be more environmentally acceptable. High density fuel racks installed to increase the storage capacity of spent fuel racks were analyzed and found to have neglialble effects on the environment (NUREG-0575). Improved technology in shipping casks has resulted in decreased exposure to transport drivers. Typical doses to drivers are half of what the FES anticipated.

A summary of'the current status of the environmental impact covered L by.the FES conclusions follows:
l .Origind A Reassignment of approximately 560 acres from agricultural and woodland use to industrial use.
+ Updtts 1 The Quad Cities Station site includes 784 acres, with an L additional adjacent undeveloped 1614 acres for future use.
l . . .- This vast land region aided in offsetting the dislocation of
[ small animals during the construction of the station and L spray canal.
- DdginaLk Construction of about 125 miles of transmission lines through mostly agricultural lands.
Update B: The original four transmission lines have not been changed from the description in the FES; however, to enhance the services provided to Citnton and other Iowa cities.
Interstate Power Company (IPH) constructed a new transmission line from the Quad Cities Station to the IPH Rock Creek substation. The transmission line travels a distance of five miles, principally in Illinois before crossing the river to the Iowa substation. The new line removed 1.13 acres of land from production in Iowa. In Illinois, 3.12 acres were affected by the construction of the transmission line because of industrial zoning requirements that were previously stipulated.
OristnaLC1 S11tation of the river and dislocation or loss of benthic organisms by construction of the diffuser pipe and dislocation of small animals caused by the construction of the spray-canal.
Updalm_C1 There was a temporary disturbance of benthic organisms and s11tation of the river during the construction of the diffuser pipe. The disturbance involved a relatively small portion of the river bottom. Sampling of the benthic organisms, following the completion of the project, showed that the organisms were able to repopulate within a very short time period.
OdsintLQ1 . Heating of 2270 cfs of Mississippi River water about 23*F above ambient untti May 1975, thereafter spray-canal hesting of about 50 cfs and evaporation of about 50 cfs. The heated ,
water from the diffuser pipe will cause a small amount of l 1
evaporation and will have a small effect on the aquatic blota which will be recoverable, s

Updait.31 The Station has returned to utilizing Mississippi River water for condenser cooling in an open-cycle mode adhering to the guidelines of NPDES Permit #1L0005037. Condenser cooling
! water is heated a maximum of 23'F above ambient at a maximum F rate of 2270 cfs and then discharged back to the river via l the diffuser pipe system.. Extensive biological monitoring
- studies of the river's ecosystem have been conducted each
- i. year and have shown that no measurable adverse effect due to Station operation has occurred on the river's aquatic community under open-cycle operation.
Oriainal E: Discharge of small concentration of chemicals that are expected to produce no deleterious effects on the environment, h Updalf_El The concentration of chemical discharges to the river have been significantly reduced since the original FES, primarily due to the use of a more environmentally acceptable sodium bromide. Chemical discharges are governed by NPDES permit
- #ILOOO5037. The Station operates in compliance with the l permit conditions and within the provisions of the Illinois Environmental Protection Act Subtitle C, Rules and Regulations of the Illinois Pollution Control Board, Iowa Hater Quality Standards, Chapters61-567 Iowa Administrative Code and the FHPCA.
Original F: Creation or enhancement of steam for during operation of the spray-canal during some periods of the year.
Update _El The spray-canal is no longer in use, therefore, mitigating the production of steam fog. The spray-canal is now used by Illinois and Iowa Department of Natural resources as a fish hatchery. The F1sh Hatchery Group is responsible for the L integration of over one half ml111on walleye and striped bass into Pool 14 and other area waters. The success of this program resulted in some economic stimulation for several segments of the local business community.
Original _G1 After modifications to both the liquid and gaseous radwaste system, there will be a discharge of small quantities of radioactive liquid and gaseous wastes to the environment, which will have a minimal effect. Prior to the modification, the levels of radioactive waste will be somewhat higher but still in accordance with the limitations set forth in 10 CFR Part 20 and 10 CFR Part 50.

.0396T:6 j
x4 s, I I
L, Update _G1 - The radioactive waste control systems for the combined normal l operation of Units I and 2 are designed to limit the !
radiation exposure of the neighboring population to levels l significantly below those doses set forth in 10 CFR Part 50, Appendix 1. The discharge of radioactive gaseous waste to I the environment were 0.005% of the Quad Cities lechnical .
Specification limit in 1988. Similarly, the activity of the 11guld waste dispensed to the environment was 0.5% of the Technical Specification limit in 1988. The amount of gaseous and liquid waste indicates that the operation of Quad Cities ,
Station has m191 mal effect on the environment.
Qtj91DAl_H1 Creation of a low risk of accidental radiation exposure to the residents In the vicinity of the site.
Update _H1 The risk associated with accidental radiation exposure remains at the very low level analyzed in the FES. The calculated total radiation doses under postulated hypothetical accident conditions to an individual at the
- boundary of the exclusion area are within the limits prescribed by 10 CFR 100.
Original _12 Creation of a low level of radiation exposure due to i transport of radioactive materials.
Undate_11 The risk of radiation exposure affiliated with the transportation of radioactive materials is in part the same with the exception of the doses incurred by the transport drivers. Improved shipping casks has effectively reduced the exposure to the drivers by approximately half of the dose referenced in the FES.

, AND_BMEEITS/EFFECl3 E0EULaI10N The population density figures used in the original FES have been L compared with the latest census figures contained in the updated FSAR, Section 2.2.3. The 1980 census figures for the total population in the 0-5 mile area around the plant is 5,641. This represents a 4.07. decrease in population since the 1970 census statistics which were included in the FES. The 1980 population density is approximately 72 people per square mile and is less than 10 people per square mile in some areas. The population ~ density is, therefore, significantly below the NRC guideline of 500.
SUMARLOLBENEEl15 The primary benefit from the continued operation of Quad Cities Station will be the generation of electricity which would have to be produced by other means if the units were retired. The cost / benefit advantage of Quad Cities, compared to alternative electric power generating capacity, improves with the extended plant lifetime. The operation of Units 1 and 2 for an additional five years and nine months, would only require incremental yearly costs. These costs.would be substatially less than the purchase of replacement power or the installation of new electrical generating capacity.
Moreover, the overall cost per year of the facility would decrease since the large initial capital outlay would be averaged over a greater number of years.
The plant is a major asset to Commonwealth Edison and the surrounding communttles by virtue of its ongoing contributions to the property tax base and secondary benefits to the local economy from employee payroll and expenditures for goods and services to operate the plant. The number of employees at the station has risen from the 180 (reflected in the FES) to the present 604, not including the contract security force. The station payroll has increased from 2.5 million to approximately 26.9 million annually. The t annual property taxes for the station has risen from 0.9 million to 1.3 l
million (State and local taxing bodies).
SUMMARLOLEEEE.CIS The continued operation of Quad Cities Station will extend the productive use of 784 acres dedicated to the station. There have been no adverse effects to the land because of the operation of the station.
Extensive studies have shown that the operation of the station in open cycle mode has had no adverse effect on the river's ecology. Extended studies on impingement and entrainment have been monitored and have shown no permanent impacts.
l RAQLQLOGLCALEfLECIS Operation of Quad Cities Station will not result in total radioactive effluent releases beyond allowable limits prescribed in Title 10 CFR Parts 20 and 50 and 40.CFR Part 190.

.0VADl lllES STATIOS l
Quad Cities Station Units 1 and 2 were designed for forty years of operation. As discussed Section 4.2.1 of the FSAR, the forty-year design life included consideration of the neutron fluence and cycilc application of
! pressure loadings and thermal transients on the reactor vessel. The NRC's I review of Quad Cities design was based on the Quad Cities FSAR, subsequent supplements and amendments. Quad Cities Unit 1 and 2 Licenses, however, o currently expire forty years from the issuance of the. Construction Permit on february 15, 1967. This results in a current licensed operating life of thirty-four years, three months, for both Units 1 and 2. The operating license for both units was issued on December 4, 1972; therefore, the current operating life of Quad Cities Station is approximately five years and nine months less than the plant's design life, 10 CFR 50.51 provides the legal basis for the issuance of Itcenses that allow for a full forty years of operation by stating:
"Each license will be issued for a fixed period of time to be specified in the license but in no case to exceed forty years from the date of issuance. Where the operation of a facility is involved, the Commission will issue the license for the term requested by the applicant or for the estimated useful life of the facility of the Commission determines that the estimated useful life is less than the term requested."
i This proposed change seeks to utilize this authority and extend the l expiration date of Quad Cities Units 1 and 2 to December 14, 2012. The extension will provide a full forty-year operating life for each unit.
l As discussed above, the useful life of Quad Cities Station Units 1 L and 2 was. intended to be forty years. In addition, the thermal and loading cycles listed in Table 4.2.1 of Quad Cities original FSAk were considered during the design process. General Electric (NSSS) performed fatigue usage analysis (Attachment 5) for the Quad Cities units using revised duty cycles.
- The analysis showed that the cumulative fatigue usage for the forty-year design life for the revised duty cycles is less than the allowable value of 1.00 for all components except the closure studs. Since the closure studs are
- replaceable, the studs will be replaced before the end of their fatigue life.
The useful life of Quad Cities Units 1 and 2, therefore, remains at the forty-year design-life.

The fact that Quad Cities Units 1 and 2 useful operating life was '
designed to be a full forty years does not imply that certain components will ,
not wear out during this time frame. The surveillance and inspection programs, that have been implemented in accordance with CFR, ASME Codes, and i the Technical Specifications will ensure that Quad Cities Station will continue to operate, as designed. In addition, these programs provirle assurance that any unexpected degradation will be detected and corrected. .
3 Examples of these requirements and programs include: l i (1) The reactor vessel surveillance program established in accordance ,
with 10 CFR 50, Appendix H.
[
(2) The fracture toughness requirements delineated in 10 CFR 50, Appendix G.
i
[ (3). 'The requirement to consider the effects of aging during the environmental qualification of the electrical equipment, as required by 10 CFR 50.49.
l (4) The inspection and testing requirement of the ASME Codes, as required by 10 CFR 50.55a.
l (5) The surveillance and operability requirements contained in the Quad Cities Technical Specifications.
(6) The dethn control reviews required by 10 CFR 50.59, which ensure the preservulon of the intended plant safety design functions.
(7) NRC and IE Bulletins which often dictate that surveillances are to be completed more frequently than CRF of ASME codes require.
The above are-examples of programs and requirements that have been implemented by Commonwealth Edison Company at Quad Cities Station. The :
appilcable programs and requirements will remain in effect throughout the remainder of Quad Cities Station Units 1 and 2 forty-year lives providing continued assurance that both units will operate safely and within all design limits.
In. summary, the extension of Quad Cities Units 1 and 2 facility Operating Licenses to forty years is authorized by 10 CFR 50.51. The addltional five years and nine months of operation will have no adverse effect on.the actual operation due to the pre-established programs that will continue to ensure safe operation as Quad Cities Station fulfills its original design lifetime.
