Operating License DPR-50 Docket No. 50-289

- TECHNICAL SPECIFICATION CHANGE REQUEST NO. 18.a. -

Licensee requests that certain changes , as hereinaf ter described, be made in Appendix B of the TMI-1 Technical Specifications. A copy of the affected pages with these changes indicated is attached.

Proposed Change Page 13, Subsection 2.2.3, pH; add the following qualifying phrase to the Specification:

. . . except that during those periods when the intake pH is greater than 9.0, the plant discharge pH shall not exceed the plant intake pH, and that during those periods when the intake pH is less than 6.0, the plant dischar te pH shall not be lower than the intake pH."

Reason for Requesting Change The subject change will eliminate the need to have to report certain conditions which the station was not responsible for having created.

The fact that fewer reports will thus have to be written will result in a cost savings, which is the reason for requesting this change.

Environmental Analysis Justifying Change The proposed change, if implemented, will not have any adverse effect on the environment, in that during periods of unusual river water conditions (i.e. , pH less than 6.0 or greater than 9.0) , the pH condition of the water which is returned to the river will be no worse, and may actually be better, than the pH condition of the river water itself.

Cost-Benefit Analysis Supporting Change No additional cost will result from implementation of the proposed change, and by making this one Limiting Condition for Operation more flexible, implementation of the proposed change will result in fewer reportable incidents, which, in turn, will result in a decrease in the number of man-hours which will have to be spent in reporting such incidents.

- TECHNICAL SPECIFICATION CHANGE REQUEST NO.18.b . -

Proposed Change Page 14, Subsection 2.2.3. , pH ; change the pH range referenced in the Bases from "6.0 to 9.0" to "5.0 to 10.0."

Reason for _ Requesting Change The reason for requesting the subject change is to make the Technical Specifications more closely reflect the actual pH conditions of the Susquehanna River. From recent sampling of the river in the vicinity of TMI-1, it appears that these conditions are more accurately represented by the range 5.0 to 10.0.

Environmental Analysis Justifying Change Because the proposed change merely serves to correct some data in the basis for a Specification, it does not constitute a change to the Technical Specification and will not cause any adverse effects to the environment. (Note: The change Specification derived from this changed Basis is addressed in the above Change Request.)

Cost-Benefit Analysis Supporting Change No additional costs will result directly from implementation of the proposed change. The benefits are as described in the above Change Request.

- TECHNICAL SPECIFICATION CHANGE REQUEST NO. 18.c. -

Proposed Change Page 45, Section 4.2.1, objective. Delete " dissolved oxygen" from the second sentence.

Reason for Requesting Change The Specification of Section 4.2.1 does not require that dissolved oxygen in the river water discharge be monitored (this requirement was removed during the draf t stage of the Technical Specifications) ;

therefore, this change is being requested so that the Technical Specifications can be made more internally consistent.

Environmental Analysis _ Justifying Change Because the proposed change merely serves to make the Technical Specifications more consistent and does not actaally change any of the requirements of those specifications, it will not cause any adverse effects to the environment.

Cost-Benefit Analysis Supporting Change No additional costs and no benefits will result from implementation of the proposed change in that all the requirements of the Technical Specifications will remain the same.

1459 277

- TECHNICAL SPECIFICATION CHANGE REQUEST NO. 18.d. -

Proposed Change Page 47, Section 4.2.1, Bases. Delete the third paragraph.

Reason for Requesting Change The Specification of Section 4.2.1 does not require that dissolved oxygen in the river water discharge be monitored; therefore, there is no need to have dissolved oxygen referenced in the Bases of this section and removal of this reference would serve to make the Technical Specifications more internally consistent.

Environmental Analysis Justifying Change The environmental Analysis is the same as for Change Request No.18.d.

above.

Cost-Benefit Analysis Supporting Change The cost-benefit analysis is the same as for Change Request No. 18.d.

above.

Eases The posteperational aquatic chemical surveillance program of the Susquehanna River in the vicinity of the Three Mile Island Nuclear Station vill begin upon the issuance of an operating license. This program is designed to provide quantitative informatien on chemical discharges frcm the plant. Chlorine discharge concentrations are monitored centinually by installed plant instrumentaticn.

It is expected that there vill be no significant difference in the concentration of heavy metals between the plant river water intake and discharge. Potential changes in concentrations of heavy metals due to passage of water through the plant could result from discharge of neutralized regenerant vastes, cerrosion of river water piping or leakage of corrorien inhibitors. The metals selected for =cnitoring vere selected based on metals kncvn to be in the river, materials used in the ccustructicn of river water syste=s and the ecmposition of the corrosion inhibitor used in the closed cooling systems. Since no significant increase in concentrations of heavy metals is expected, the measurement downstream is unlikely to be of value in defining the chemical plume.

1 The only significant addition of dissolved solids to plant effluent is the discharge of neutralized regenerant vastes from the cycle makeup demineralizers. In addition, dissolved solids are concentrated in cooling tower blevdown due to evaporatien loss in the ecoling towers. Since limits are placed on discharge of dissolved solids by Specificatien 2.3.2 and concentrations are acnitored en a minimum veekly frequency during plant operation, the inclusion of this parameter with the postoperaticnal surveillance progra= after a period of 1 - 3 years is censidered unnecessary.

There is expected to be no significant addition of suspended solids to the plant discharge. A period cf 1 - 3 years inclusion of th.s parameter within the postoperational surveillance program is con-sidered sufficient to justify efficiency and reliability of plant 1459 279

chemically mialyzed for drift minerals.

This progra= vill be continued for two years.

Bases Since so=e potential exists for damage to area vegetation frca cooling tower drift and since the actual effect is unkncvn, specific report levels, protection limits, or the need for such =easures cannot be determined at this time. The study described herein vill provide information needed to establish a protection limit or report level er to establish that the =easurement of the drift effect is unnecessary due to insignificant i= pact.

Measurement of species composition, relative abundance , and relative dc=inance vill determine changes in the natural vegetative cc=munity that may be due to plant operation. Increases or decreases in cer-tain species should beccme evident if they do in fact occur. Examina-tion of vegetation for physical disorder 3 vill indicate if salt damage is cecurring with respec', to actual injury or death of plants.

This information vill be supplemented by analyses to determine con-centrations of certain minerals in the plant material.

h.2 Chemical h.2.1 Aquatic Objective To define operational surveillance or special studies of aquatic chemical effects derived frcm the station. The che=ical parameters of this study will include chlorine, heavy metals , suspended solids I and dissolved solids. Alkalinity is related to the pH of the water and may be included if deemed necessary in checking pH =enitcring at the river water discharge.

Specification The aquatic chemical surveillance program shall be conducted as follows:
