1. Which of the following current techniques for at-reactor storage are you using and how?

A. Re-racking of spent fuel B. Control Rod Repositioning (deleted)

C. Above ground dry storage D. Longer fuel burnup E. Other

Response

A. The Cooper Nuclear Station (CNS) spent fuel original configuration had cpace for 740 fuel assemblies. The spent fuel pool was re-racked in 1978-1979 to increase capacity to its present value of 2366 fuel assemblics.

B. (Deleted)

C. None D. The District is presently in transition to enhanced design fuel that is expected to increase discharge burnup to approximately 36,000 MWD per metric ton. This is an increase of about 4,000 -

5,000 MWD per metric ton over current values.

E. None

2. Do you plan on continuing the use of these current techniques for at-reactor storage of spent fuel during the remaining time of your operating license or do you expect to chance or modify them in some way?

Response

The District plans to continue using current techniques.

3. Which of the following techniques for at-reactor storage do you anticipate using until off-site spent fuel storage becomes availabic and how?

A. Re-racking of spent fuel B. Centrol Rod Repositioning (Deleted) +.

C Aoove ground dry storage D. Longer fuel burnup E. Other (please identify)

• NL59000290 Pcgs 2 of 33

Response

A. At some time in the future the District will probably consider additional re-racking of the spent fuel pool as well as dry storage for further expansion of spent fuel storage capacity.

B. (Deleted)

C. See response to A D. The District plans to evaluate and possibly utilize future extended burnup fuel designs as they become available.

E. None

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?

Pesponse:

The techniques described above should be adequate for the remaining lifetime of CNS including recapturing the construction pemit to operating license time period. The District has not considered any additional operation beyond this tem (i.e. 20 year license renewal).

Consequently, no assessment of spent fuel storage for license renewal has .seen performed.

5. Do you anticipate the need to acquire additional land for the storage of spent-fuel for the operating lifetime of the plaat, including a 20-year period of license renewal? If so, how much land? When would this acquisition occur? Where? (if answer "yes", 3-4 sentences)

Response

Adequate land appears to be available at the existing site so no acquisition should be needed in the future.

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)

+.

Response

Additional construction activity will take place in connection with increased spent fuel storage capacity on-site. This will be in the form of either re-racking of the storage fuel or building above ground dry storage areas,

B. Low Level Radioactive Waste Management Questions

1. Under the current scheme for LLRW disposal (i.e.- LLRW Policy 1 Amendments Act of 1965 and regional compacts) is there currently or j will sufficient capacity for wastes generated during the license renewal period be available to your plent(s)? If so, what is the basis for this conclusion?

Response: ,

1 i

Yes. Nebraska is a member of the Central Interstate Low-% vel Radioactive Waste Compact Commission. The Central Interstate Low-Level Radioactive Waste compact Commission . was ratified by the ]

U.S. Congress in 1985 with Nebraska being selected as the host  ;

disposal state in 1988. If siting and d6velopment plans proceed as presently scheduled, HPPD believes that these arrangements will j satisfy the low-level radioactive waste disposal requirements of Cooper Nuclear Station throughout its operating life.

f

2. If f or any reason your plant (s) is/are denied accees to a licensed disposal site for a short period of time, what plans do you have for continued LLRW disposal?

Response

In 1984 NPPD designed and constructed a Low-Level Radioactive Waste (LLRW) Storage Facility at the Cooper Nuclear Station (CNS) site. The design and construction of this f acility was -based on existing NRC LLRW Storage Facility guidelines and licensing requirements.

Although the NRC review of the facility for compliance with LLRW Storage Facility licensing requirements has not yet been completed, because of the lack of need to fully utilize the facility, NPPD anticipat es this f acility could be, used to temporarily store the LLRW generated at CNS during any five year period.

3. In a couple of pages, please describe the specific methods of LLRW management currently utilized by your plant. What percentage of your current LLRW (by volume) is manage by:

A. Wasto compaction?

B. Waste Segregation (through special controls or segregation at radiation check point)?

C. Decontamination of wastes?

D. Sorting of waste prior to shipment?

E. Other (please identify)

(Such as solidification of liquids and resins, dewatering of resins)

3. Continued

Response

Dry Active Waste Compaction 41%, 4,900 Ft."

Dewatering of resins / sludges 40%, 4,800 Ft."

Cement Stabilization of resins / sludges 4%, 480 Ft."

Solidification of oils 2%, 240 Ft."

Dry Active Waste Solidification 3%, 400 Ft."

Noncompactible Dry Active Waste 10%, 1,200 Ft."

Waste Segregation 0%

Decontamination of Waste 0%

Sorting of Waste 0%

The management of LLRW at NPPD's CNS can be categorized into shredding and supercompaction of dry active waste, cement stabilization of Class B resins and sludges, dewatering of Class A resins and sludges, solidification of oils and dry active waste, and crating of noncompactible dry active waste.

Inherent to the management of LLRW is the minimization of nonradioactively contaminated material introduction into the CNS Controlled Area (RCA). Reuse of radioactively Radiologically contaminated tools and equipment ip the RCA is commonly practiced to assist in minimizing the introduction, influx, etc. of clear materials in the RCA.

Although LLRW is not decontaminated, attempts are made to decontaminate reusable tools and equipment which have become radioactively contaminated. Materials which e-e' successfully decontaminated are released for unrestricted use. haterials which cannot be decontaminated are either reused in the RU., disposed of as radioactive waste or shipped to other licensees who may have a use for the material. .,

Clean materials are not sorted out of LLRW prior to waste processing or shipment, because station practices preclude very little clean material from entering the waste stream and due to the cost effectiveness of such a practice.

4. Continued operating license and through the license renewal term. What percentage of your anticipated wasta (by volume) will be managed by:

A. Waste compaction?

B. Waste segregation (through special controls or segregation at radiation check point)?

C. Decontamination of wastes? _

D. Sorting of waste prior to shipment?

E. Other (please identify)

Response

Waste compaction / incineration 40%

Dewatering of resins 40%

5%

Cement Stabilization of resins Dry Active Waste Solidification 5%

Decontamination / recycling of waste 5%

Non Compactible Waste St Waste Segregation 0%

Sorting of waste 0%

NPPD anticipates only minor sprovements in the management of LLRW at CNS during the remainder of the operating license and through the license renewal term. Improved LLRW management techniques currently under investigation include incineration of dry active waste and equipment of1, smelting of nonincinerable naterials, abrasive decontunination of large components and component recycling.

if economically feasible, the combined effect of these improved LLRV management techniques could reduce the total volume of LLRW generated at CNS by an estimated 30%. This equates to a reduction in LLRW burial volumes of approximately 3,000 Ft." per year. -

Use of the recently announced Below Regulatory Concern policy by the NRC will have little impact on the management of LLRW at CNS.

No.

6. To provide information on the timing of tuture low-level waste streams, if you answered yes to question #3, over what periods of time are these activities contemplated? l

Response

Approximately 1992, 1999, 2006, and 2013.

7. Do you anticipate any additional construction activity, on-site, or ina sdiately adjacent to the power plant site, associated with temporary LLRW storage for the operating lifetime of the plant, including a 20-yer.r period of license renewal? (yes/no)

Response

No.

O. If you-answered yes to question #7, briefly describe this construction activity -(e.g., storage areas for steam generator components or other snaterials exposed to reactor environment).

Response

Not applicable.

9.: To provide information on future ' low-level waste streams which may

- effect workforce levels, exposure, and waste compact planning, do you anticipate any major plant modifications or refurbishment that are likely to generate unusual volumes of low-level radioactive waste prior to, ~or during, - the relicensing period for the plant? If so, please describe the m activities. Also, what types of modifications do you anticipate 1 Oe necessary to achieve license renowal operation through a 20-year license renewal tenn?

Response

Currently no major plant modifications or refurbishments are expected or planned which would generate unusual volumes of LLRW prior to, or during, the relicensing period for CNS. Waste volumes generated from routine preventative and corrective maintenance activities should remain relatively constant.

Attechment to NLS9000298 Page 9 of 33 AQUATIC RESOURCE QUESTIONS

1. Post-licensine modifications and/or chances in enerations of intake And/or discharce systems may have altered the effects of the noyty niant on nouatic resources. or may have been made specifically to mitirate imoacts that vere not anticinated in the desien of the nient. Describe

-any such modifications and/or ooerational_shances to the condenser cooline water intake and discharce systems since the issuance of the Operatine License.

Only one modification has been made to the intake structure which-involved the building of a guide wall in front of the intake structure to help reduce the deposit of sediment in this area. The guide wall is constructed of Z piling driven to rock. The wall is set out 14 feet from the intake structure into the river and is about 276 feet in total length and extends from above the intake strveture downstream past the inlets, approximately 10 feet.

2. Summarize and describe (or orovide documentation of) any known imonets on nouatic resources (e.c. fish kills. violations of dischgree nermit conditions) or National Pollutant Discharee Elimination System (NPDES) gnforcement actions that have occurred since issuance of the Operatine Licence. How have these been resolved or chanced over time? (The Irsconse to this cuestion should indicate whether impacts are oncoine gr were the result of start-up oroblems that were subsequentiv resolved.)

Various NPDES noncompliances have occurred over the last 14 years. The majority of the violations have been associated with two outfalls 004 and 005. The 004 outfall discharges wastewaters from the sludge settling pond which receives wastes from the water treatment operation.

The 005 outfall was designed to discharge wastewater from the mechanical sewage treatment plant, ,

The 005 outfall experienced several noncompliances per year from 1976 until 1987 when the discharge vu eliminated. The mor.t common violations occurred with exeseding the permit limitations for BOD and TSS. A Complaint, Compliance Ordt r 'and Notice of Opporcunity for Hearing (Case No. 913) was ' issued to NPPD on July 15, 1986 by the Nebraska Department of Environmental Control. NPPD was ordered to replace the existing mechanical sewage plant with a complete retention lagoon facility. The problem was resolved with the construction of two wastewate evaporation lagoons on August 10, 1987. The 005 designation was cificially removed from the CNS NPDES permit on January 25, 1988.

No discharges have occurred from this outfall vntil May of this year whea because of increas'ed flows from the most recent plant outage and heavy rains, wastewater had to be released to the Missouri River. The discharge lasted apprcximately one month. The ponds wer,e lowered down to a 2 1/2 foot level. The discharge event was completed under direction from the NDEC.

The-004 outfall has also experienced several noncompliances since 1977 with the majority of these events occurring during 1987. The reason for the noncompliance events is related to regulating the pH of the discharge. The levels of pH have ranged from 1.0 to 11.5 during these violations. Although no legal enforcement actions were initiated by the

, i .

Attochment to NLS?000298 Page 10 of 33 NDEC, they did formerly request in a letter on March 24, 1987, that the District resolve the problem and submit periodic progress reports and completion schedules. To control this problem, modifications were implemented including a pH neutralization system which was installed in August 1989. The system is designed to control the flow and pH of water through this discharge by automatic neutralization with CO2. Two noncompliances have occurred since this system was installed both related to viring problems within the system.

As part of the effort to eliminate the NPDES noncompliances associated with the 004 discharge, the following modifications were also completed by August 24, 1989.

1. The clearwell overflow was rerouted to the 002B outfall.

2. A pH-controlled isolation valve on the clearwell overflow line was installed that will divert the flow from the 002B outfall to the sludge settling pond (004) if the pH is not between 6 9. .

3. The dilute acid system which regulates the pH of the circulator effluent was automated.

4. The auxiliary boiler blowdown was rerouted from the 002C outfall to the 004 outfall.

5. The automated pH adjustment syntem fr the 004 outfall was installed.

Occasionally during the summer months and especially the last three summers the 001 outfall (cooling water discharge), which consists of once-through cooling water, has exceeded the NPDES permit limitation for temperature. A few of the non' compliances have occurred due to maintenance activities, however during the last couple of years, increase ambient river temperatures have contributed to several violations.

No recorded or reported fish kills have been associated with any of the noncompliance events experienced at CNS.

3. Chances to the NPDES vermit durinc overation of the olant could indicate whether water cuality carameters were determined to have no sienificant imunets (and were dronoed from monitorine recuirements) or were subsecuentiv raised as a water cuality issue. Provide a brief summary of chances (and when they occurred) to the NPDES vermit for the niant since issuance of the Ooeratine License.

4. An examination of trends in the ef fects on acustic resources monitorinc can indiente whether impacte have increased. decreased. or remained relatively stable durine coeration. Describe and suenarize (or provide documentation of) results of monitorinc of water cuality and nountic biota (c.c. related to NPDES vermits. Environmental Technical Specifications. site-specific monitorine_,reouired by federal or state aggnetes). What trends are avoarent over time?

Preoperational ar,uatic monitoring studies were s.cnducted on the Missouri River from 1969 through 1973. The operational aauatic monitoring program was conducted from 1973 through 1979; sinae that time no environmental studies have been conducted. Note:

impingement / entrapment studies at the intake structutss continued through 1983. Monitoring of the aquatic system ended in 1979 because it was determined by the extensive data collected that operation of CNS had not adversely impacted the water quality or aquatic ecology of the Missouri River. The following is a brief summary of the results of monitoring of water quality and aquatic biota, ,

Water Quality Water quality studies in the Missouri River near CNS were conducted from 1971 through 1979. The results from these water quality studies (1971 through 1979) indicated that water quality in the Missouri River was not adversely affected by the operation of CNS. Watt:r quality data are attached (see Table 2.9).

Periphytor.

Preoperational baseline data on periphyton abundance, species composition, community structure, and biomass production in the Missouri River near CNS were collected in 1972 and 1973. Data on the effects of operation of CNS on the downstream periphyton community were gathered from 1974 through 1979. All measurements of the periphyt'on community in 1979 yielded results that were within the range of value previously reported for the Missouri River near CNS (see attached Table 3.1).

Fish Impingement Fish oI the Missouri River near CNS were studied from 1970 through 1973 (preoperational) and 1973 through 1983 (operational). There has been an

Attechment to NLS9000298 Page 12 of 33 insignificant impact on the adult fish populations near CNS due to impingement entrapment lossss. Table 9.12 (see attached) gives the relative abundance and impingement rates of fish impinged at CNS from 1973-1977. Table 10 (see attached) contains actual impingement numbers for fish impinged at CNS from 1978 till 1983.

Macroinvertebrates In 1972 a series of studies were initiated to provide information on the composition and abundance of macroinvertebrates in the Missouri River-near CNS. Species composition and densities of aufwuchs and benthic communities sampled near CNS in 1979 were similar to those in previous studies. Results of operational studies conducted from 1974 to 1979 indicate that heated water from CNS has not adversely affected aquatic macroinvertebrate populations in the Missouri River near CNS. Table 4.1 gives a summary of macroinvertebrate occurrence in benthic and aufwuch samples near CNS from 1973-1979.

Larval Fish Entrainment Larval fish studies were initiated in 1973 to document the mechanical effects of condenser passage and the abundance and distribution of fish larvae in the Missouri River near CNS. Net-induced mortality resulting from high current velocities frequently caused intake mortalities to exceed those in the discharge; therefore, the entrainment study was discontinued in 1977 and entrainmen'. losses have subsequently been estimated with the horizontal distribution data. Estimates for 1977 through 1979 are as follows:

1979 - An estimated 3.3% of the larval fish passing the station were entrained. ,

1978 - An estimated 3.7% of the larval fish passing the station were entrained.

1977 - An estimated 7.6% lof the larval fish passing the station were entrained.

Entrainment losses were probably less than the estimated entrainment rates since previous studies at CNS have shown that fish larvae can survive condenser passage.

5. Summarize tvoes and numbers (eg. provide documentation) of organisms entrained and imoinced by the condenser cooline water system since issuance of the Ooeratine License. Describe any seasonal natterns associated with entrainment and imoincement. How has entrainment and

~

imoincement chanced over time?

Documentation has been provided that summarizes the types and numbers of fish entrained and impinged by the condenser cooling water system during both preoperational and operational phases. Tables 9.12, 9.13, 9.14, and 9.5 present data on the numbers of fish entrapped or impinged at CNS. High fish impingement rates were associated with high reproduction and survival during 1975 and 1976. Most fish impinged belonged to a = .

l Attachment to i

NLS9000298 Page 13 of 33 year-class O to 11. Generally the impingement rates were highest from July through December and data shown that most of these fish were young-of-the year.

Zooplankton entrainment ctudies were conducted at CNS during 1973 (preoperational) and 197i. through 1976 (operational) to document the combined thermal and mechanical effects of condenser passage on zooplankton viability. Estimated impact of entrainment on the total Missouri River zooplankton community passing CNS did not exceed 0.6 percent in 1976 and the previous years had similar numbers. Species composition and seasonal changes of major zooplankton were similar during preoperational and operational studies. Station operation has had no apparent effect on zooplankton abundance, species diversity, or distribution. Table 9.2 is a summary of differential immobility and mortality for total zooplankton following condenser passage at CNS.

Phytoplankton species composition was generally not affected by condenser passage; therefore, the mechanical effect of condenser passage on the Missouri River phytoplankton population is considered negligible.

6. Aountic habitat enhancement or restoration efforts (e.c. anadromous fish runs) durine operation may have enhanced the biolocical communities in the vicini ty of the olant. Alternative 1v. decradation of habitat or water cuan tv may have resulted in loss of biolocical resources near the site. Describe any chances to acustic habitats (both enhancement and derradction) in the viciniry of the vower olant since the issuance of the Overatine License includinc those that may have resulted in different niant imnacte than those initially credicted.

The District has not conducted monitoring studies cince 1979, howeier, the only observed change that has occurred over the last few years is the increased ambient temperatures of the Missouri River during the summer months. Whether this has any impact on aquatic habitats is not known but it has had an impact in causing the Station to exceed their NPDES permit limitation for temperature.

7. Plant overations may have had vositive. necative. or no innaet on the use .of aauntic resources by others. Harvest by commercial or recreational fi she rmen may be constrained by plant operation.

Alternatively _ commercial harvestine may be relativelv 1arce compared with fish losses caused by the niant. Describe (or vrovide documentation for) other nearby uses of waters affected by cooline water systems (e.c. swimmine. boatine. annuni harvest by commercial and recreational fi she rie s )- and how these imoacts have chanced since issuance of the Operatinc License.

h None of the nearby uses (commercial and recreation fishitig uses) of the Missouri River have been affected by plant operation (cooling water discharge) since the issuance of the Operating License (Nebraska Game and Parks Commission, 1990 Verbal Communication). The thermal effluent from CNS is dispersed within a short distance of the outfall, therefore, the thermally affected area of the Missouri River is small. Chemicals are not required to clean intake water lines due to the abrasive nature 5-

Attechm2nt to NLS9000298 Page 14 of 33 of the sediment of the river. The movement of marked fish demonstrated that the thennal plume presented no barrier to the movement of fish.

8. Describe other sources of imonets on souatic resources (e.c. industrial discharces. other nower clants. atricultural runoff) that could contribute to cumulative inonets. What are the relative con ibutions by nereent of these sourecs. includine the contributions due o the cover clant. to overall water cuality decradation and losses of acustic biota?

To our knowledge, the only potential source of impact introduced to this aquatic system since the issuance of CNS's Operating License is the Omaha Public Power District's Nebraska City Station, coal fired plant located approximately 30 miles upstream of CNS. Whut effect this plant has on the cumulativa impact of the system has not. been studied or determined.

9. Provide a copy of your Section 316(a) and (b) Demonstration Reoort reauired by the Clean Vaste Act. What Section 316(a) and (b) determinations have been made by the reculatory authorities?

On May 4, 1976 the Nebraska Department of Environmental Control indicated the reviewing agencies (NDEC, EPA, NGPC, and USWS) concluded that the discharge of once-through cooling water had not caused any appreciable harm to the aquatic community of the Missouri River 1.nd approved the District's waiver for alternate thermal limits.

On February 2,1977 the NDEC informed the District that the CNS intake structure meets the minimum requirements of Section 316(b) of P.C.92-500 and no backfitting of fish protection was required. The NDEC requested repot ts concerning fish impingement and entrainment be submitted to them. On January 5, 1978 the NDEC found that the NRC impingement sampling program was adaquate for the NPDES requirements. -

On November 7, 1983 the NDEC notified the District that the CNS intake structure had been designed and constructed in such a way to minimize adverse impacts on the fishery and that no further fish impingement studies were required.

The discontinuance of all thermal and aquatic monitoring studies were approved by the NRC and deleted from the Environmental Technical Specification.

A copy of the CNS 316(a) and (b) demonstration document is enclosed.

Case C The largest single outage occurred from September 15, 1904 to August 20, 1905 and involved, among other things replacement of the recirculation, Residual Heat Re:noval, Core Spray and Reactor Water cleanup system pipe due to ICSCC. This outage utilized 2076 total contract personnel on site and approximately 1900 person-rem of collective dose was received.

4. -To understand the plant's fiscal importance to specific jurisdictions, for 1900, 1985, and the latest year for which data are available, estimate the entire plant's taxable assessed value and the amtunt of taxes paid to the state and to each local taxing jurisd)ction.

Response

Linder Nebraska State law, the District f.s a political subdivision of the state and is exempt from taxation by the state and local government.

Consequently, there is not tax amount directly associated with the Cooper Nuclear Station. The plant payroll for,1990 was greater than $14,00,000.

In terms of the plant's taxable assessed value, reports are prepared for insurance purposes which identify both book cost and a calculated replacement cost using the Handy-Whitsnan Index. The replacement cost of for insurance purposes and may not be a realistic assessment of replacement cost for an identical facility today. Dcta from these reports is as follows:

Various NPDES noncompliances have occurred over the 1rst 14 years. The majority of the violations have been associated with two outfalls 004 and 005. The 004 outfall discharges wastewaters from the sludge settling pond which receives wastes from the water treatment operatlon.

The 005 outfall was designed to discharge vastewater from the mechanical sewage treatment plant.

The 005 outf all experienced severa; noncompliances por year from 1976 until 1987 when the discharge was eliminated. The most common violations occurred with exceeding the permit limitations for BOD and TSS. A Complaint, Conipliance Order and Notice of Opportunity for llearing (Case No. 913) wa issued to NppD on July 15, 1986 by the Nebraska Department of Environtnental Control . dpfD was ordered to replace the existing mechanical sewage plant with a coitiplete retention lagoon facility. The problem was resolved with t.he construction of two wastewater evaporation lagoons on Au6ust 10, 1987, The 005 designation was officially removed from the CNS NPDES permit on January 25, 1988.

No discharges have occurred from this outfall until tiny of this year when because of increased flows from the most recent plant outage and heavy rains, wastewater had to be released to the Missouri River. The discharge lasted spproxima%1y one month. The ponds were lowered devn to a 2 1/2 foot level, ' he discharge event was completed under direction irom the NDEC.

The 004 outfall has also experienced several noncompliances since 1977 with the majority of these events occurring during 1987. The reason for the noncompliance events is related to regulating the pil of the discharge. The Icvels- of pil have ranged f rom 1.0 to 11.5 during these violations, Although no Icgal enforcemenc actions were initiated by the

e , e Attachment to NLS9000298 page 10 of 33 NDEC, they did formetly request in a letter on March 24, 1987, that the District resolve the problem and submit periodic progress reports and completion schedules. To control this problem, modifications vere implemented including a pH neutralization system which was installed in August 1989. The system is designed to control Lhe flow and pit of water through this discharge by automatic neutralization with CO2. Two noncortpliance s have occurred since this systen, was installed both related to wiring problems within the system.

As part of the effort to elitninate the NPDES noncompliances associated with the 004 discharge, the following modifications were also completed by August 24, 1989.

1. The clearwell overflow was rerouted to the 002B outfall.

2. A pil. controlled isolation valve on the cicarwell overflow line was installed that will divert the flow from the 002B out fall to the sludge settling pond (004) if the pil is not between 6 9.

3. The dilute acid system which regulates the pit of the circulator effluent was automated.

4. The auxiliary boiler blowdown vss rerouted from the 002C outfall to the 004 outfall.

5. Thn automated pil adjustment system for the 004 outfall was installed.

cecasionally during the stumer months and especially the last three stunmers the 001 outfall (cooling water discharge), which consists cf once through cooling water, has exceeded the NPDES permit limitation for temperature. A few of the noncompliances have occurred due to maintenance activities, however during the last couple of years, increase ambient river temperatures have contributed to several violations.

No recorded or reported fish kills have been associated with any of the noncompliance events experienced at CNS.

Wh_a t trends are nonarent over ting 2 prooperational aquatic inonitoring studies were conducted on the Missouri River frotn 1069 through 1973. The operational aquatic monitoring program was conducted frorn 1973 through 1979; since that time no environmental studies have been conducted. Note:

iropingersent/ entrapment studies at the intake ntructures continued through 1983. Moaltoring of the aquatic system ended in 1979 because it was determined by the extensive data collected that operation of CNS had not adversely impacted the water quality or aquatic ecology of the Missouri River. The following is a brief summary of the results of monitoring of water quality and aquatic biota, Water Quality Water quality studies in the Missouri River nnar CNS were conducted from 1971 through 1979. The results from the e water quality studies (1971 through 1979) indicated that water quality in the Missoari River was not adversely affected by the operat;on of CNS. Water quality data are attached (see Table 2.9).

Periphyton Preoperational baccline data on periphyton abundance, species corrposition, community structure, and biomass production in the Missouri River near CNS were rollected in 1972 and 1973. Data on the effects of operation of CNS or the downstream periphyton community were gathered from 1974 through 1979. All incasurements of the periphyton community in 1979 yielded reanits that woro within the range of value previously reported for the Missouri River near-CNS (see attached Table 3.1).

-Fish Impingement Fish of the 'tissouri River near CNS were studied from 1970 through 1973 (preoperatianal) and 1973 through 1983 (operational). There has been an

Attachment to NLS9000298 Page 12 of 33 insignificant impact on the adult fish populations near CNS due to l impingement entrapment losses. Table 9.12 (see attached) gives the i relative abundance and impingement rates of fish impinged at CNS from 1973 1977. Table 10 (see attached) contains actual impingement numbers for fish impinged at CNS frota 1978 till 1983.

Macroinvertebrates In 1972 a series of studies were initiated to provide information on the composition and abundance of macroinvertebcates in the Missouri River near CNS. Species composition and demities of aufwuchs and benthic communities sampled near CNS in 1970 were similar to those in previous studies. Results of operational studies conducted from 1974 to 1979 indicate that heated water froin CNS has not adversely affected aquatic l macroinvertebrate populations in the Missouri River near CNS. Table 4.1 l gives a summary of in:.croinvertebrate occurrence in benthic and aufvuch l samples near CNS from 1973 1979.

Larval Fish Entrainment 1

1.arval fish studies were initiated in 1973 to document the mechanical effects of condenser passage and t5 e abundance and distribution of fish larvae in the Missouri River near CNS. Net. induced mortality resulting from high carrent velocities frequently caused intake mortalities to exceed those in the discharge; therefore, the entrainment study was discontinued in 1977 and entrainment losses have subsequently been estimated with the horizontal distribution data. Ea tin.a te s for 1977 through 1979 are as follows: '

1979 An estimated 3.3% of the larval fish passing the station were ,

entrained.

1978 An estimated 3.7% of the larval fish passing the station were entrained.

1977 - An estimated 7.6% of the larval fish passing the station were entrained.

Entrainment losses were probat ly less than the estimated entrainment rates since previous studies at CNS have shown that fish larvae can survive cot. denser passage.

5. Summarite tvoes and numbers (or provide documentation) of ornanisms entrained and imninced by the condgnger cooline water system since issuance of the Operatine Licensem Describe arv nensonal untterna associated with cntrainment and imninnement. How has entratIEtut and imninrement chanced over time?

Documentation has been provided that summarizes'the types and numbers of-fish entrained and impinged by the condenser cooling water systern during both preoperational and operational phases. Tables 9.12, 9.13, 9.14, and 9.5 present data on the munbers of fish entrapped or impinged at CNS. High fish impingement rates were associated 'rith high reproduction and survival during 1975 and 1976. Most fish impinged belonged to 4

l Attachment to NLS90002;8 Page 13 of 33 l

year class 0 to 11. Oe-rally the impingement rates were highest from July through December and data shows that most of these fish were young-of the year.

Zooplankton entrainment studies were conducted at CNS during 1973 (preoperational) and 1974 through 1976 (operational) to document the combined thermal and mechanical effects of condensor passage on zooplankton viability. Estimated impact of entrainment on the total Missouri River zooplankton community passing CNS did not exceed 0.6 percent in 1976 and the previous years had similar numbers. Species composition and seasonal changes of major zooplankton were similar during preoperational and operational studies. Station operation has had no apparent effect on zooplankton abundance, species diversity, or distribution. Table 9.2 is a summary of differential immobility and mortality for total zooplankton following condenser passage at CNS.

phytoplankton species composition was generally not affected by condenser passage; therefore, the mechanical effect of condenser passage on the Missouri River phytoplankton population is considered negligible.

6. Aaustic habitat enhancement or restoration efforts (e.c. anadromous fish runs) durine operation may have enhanced the biolonien1 communities in the vicinity of the vlant. Alternatively. degradation of hnbitat_ n vater cuality may have resulted in loss of biolorical resourcen near the site. Descrihe any channes to nountic habitats (both enhancement and dryyidation) in the vicinity of the nover niant since the issuance of the Operatine License includine those that may have resulted in different niant innacts than those initially predicted.

The District has not conducted monitoring studies.since 1979, however, the only observed change that has occurred over the last few years is the increased ambient temperatures of the Missouri River during the summer months. Whether this has any impact on aquatic habitats is not known but it has had an impact in causing the Station to exceed their NPDES permit limite* ion for temperature,

7. Plant operations may have had nositive. nerative. or no innact on the use of aauntic resourecs by others. Harvest by commercial or recreational fishermen mnv be constrained by plant operation.

Alternatively commercial harvestine may be relativelv 1arge comngred with fish losses caused by the niant. Describe (or nrovide documentation for) k*-hM nearby uses of waters affec,cd by cooline water systems (e.c. swimmine. boatine. EDunal harvest by commercial and recreational fisheries) and how these innacts have chanced since issuance of the Operatine License.

None of the. nearby uses (commercial and recreation fishing uses) of the Missouri River have been affected by plant operation (cooling water discharge) since the issuance of the Operating License (Nebraska Game and parks Commission, 1990 Verbal Communication). The thermal effluent from CNS is dispersed within a short distance of the outfall, therefore, the thermally affected area of the Missouri River is small. Chemicals are not_ required to clean intake water lines due to the abrasive nature 5-

_ - - _ , ~ _

"w2 Attachment to NLS9000298 Page 14 of 33 of the sediment of the river. The tnovernent of marked fish demonstrated that the thermal plume presented no barrier to the movement of fish.

8. Describe other sources of imoacts on nouatic resources (e.c. Indug. trial discharces. other nower lants. arricultural runoff) that could contribute to cumulative imoacts. Vhat are the relative contributions by cercent of these sources. includinn the contributions due to the power plant. to overall water m ality denradation and losses of acuatic biota?

To our knowledge, tha only potential source of impact introduced to this aquatic system since the issuance of CNS's Operating License is the Omaha Public Power District's Nebraska City Station, coal fired plant located approximately 30 toiles upstream of CNS. What effect this plant has on the cumulative impact of the system has not been studied or de te rtained.

9. Provide a coov of your Section 316(a) and (b) Demonstration Renort reouired by the Clean Vaste Act. What Section 316(a) and (b) determinations have been ende by the reculatory authorities?

On May 4, 1976 the Nebraska Department of Environmental Control indicated the reviewing agencies (NDEC, EPA, NGPC, and USFWS) concluded that the discharge of once through cooling water had not caused any appreciable harm to the aquatic community of the Missouri River and approved the District's waiver for alternate thermal limits.

On February 2, 1977 the NDEC informed the District that the CNS intake -

structure meets the rainimum requirements of Section 316(b) of P.C. 92 500 and no backfitting of fish protection was required. The NDEC requested reports concerning fish impingement and entrainment be submitted to them. On January 5, 1978 the NDEC found that the NRC impingement-sampling pr? 2.n was adequate for the NPDES requirements. '

On November 7, 1983 the Q EC notified the District that the CNS intake structure had been designed and constructed in such a way to minimize adverse itnpacts on' the fishery and that no further fish -impingement studies were required.

The discontinuance of all thermal'and aquatic monitoring studies were approved by the NRC and deleted from the Environmental Technical Specification.

A copy of the CNS 316(a) and (b) demonstration document is enclosed.
