~ 1 UKE POWER COMPANY OCONtc NUCLEAR STATION - UNIT I RESPONSE TO RO INSPECTION REP'F.T 50-269/73-13 1.A.I.c Cheniccl Discher~e Lirits The re:imum poscible conenntration cf boric ecid resulting in the Kecuec River at specified in Section 1.2 F the Oconce Non-Rediologiccl Environment Technicci Specifications is 8.8 x IC-"ppr, a factor of 10 lets than the naturally occurring cen:2ttration of boron the river.
This specification, as written, cannot be successfully implerented. A request for a change of this technicci specifi-cction IImit wts forwarded to the Directortte of Licensinc on December 13, 1973 We have been i formed by the Directorate of Licensir.g that the proposed change he been revics.cd and cppreved and : hould be isst J very soca.
l.A.I.5 Ueste Water Collection E+ sin Effluent oH Techniccl Spe:ificaticn 1.29 of Appendix E new states that all water discharged from the ucste water collection basin shall have a p: between 6.0 and 6.5 The pH of the efflucnt f.am the bcsin is not alwcys representative of the actual discharge to the Keowee River bccause of the influence of other local drainage waste streans.
Although the specificction has not been met on many occasions when measuring pH at the basin discharge, the pH of effluent entering the Keo..ce River has been between 6.0 and 8.5 except for two instances.
Since we believe the specification should apply to the -tual effluent entering the river, we have proposed to the Directorate of Licensicg that the specification be revised such that the actual discharge to the Keowee Piver shall have a pH between 6.0 and 8.5 If the revision is approved, the pH would be determined daily, whc n discF rges are made from the waste water collection basin, from a representative sample collected from the combined effluent stream before it discharges to the river.
In addition to this request for a change to the technical specification, a work order has been issue: for an additional waste water handling and collection facility to double present capacity.
The two basins will provide separated capability for collection and discharge, plus increased capability for recircu-lation to allow an eight-hour turnover of volume.
This will permit better control i
of chemistry prior to discharge.
l.A.I.c pH and Seccific Conductance Monitorino l
The waste water collection basin effluent pH and specific conductance was not recorded for a total of 25 days during the period Jc y 10 through November 14, 1973 On these days, we believe the waste water collection basin was either drained or there was no discharge.
It is now required that an appropriate entry be made on the daily chemistry report to reflect the status of the collection basin.
1.A.I.d Dissolved Oxycen Measurements Although the operating license for Oconee I was issued on February 6, 1973, the environmental monitoring program required by that license was not completely l
l implerented until June, 1973 The environmental ttchnical specificatiens were i
j not finalized until approximately two months before license issue; consequently,

sufficient manpower could '~
be eroloyed, trained and alle'~ted until June, 1973
,T,he hirectorate of Licensing environmental projects staff we, advised of this dclay in implementa*. ion and did not express concern.
Consequently, weekly distolved oxygen measure:nts were made at the three spccified locations after the monitoring progran tas initiated on June 8, 1973, except during the weeks of July 1, July 8, July 29, August 19, and Scptembcr 9, 1973 when they were inadecrtertly not nade.
T,esults of the weekly monitoring program for the month of Jenc 1573 have becn rcLorted in Table 1.3.1-10A of the Ocor.ee Nuclear Station Seni-/nruni Repo t for the period ending June 30, 1973 4
Arrangements have been rade for operation of Keowce Hydroelectric Station as re-quired to facilitate t'c proper secpling of the Keowee tailrace.
To assist in the administration and execution of non-radiologictl environmental monitoring cnd surveillcnce procedures, cnother person, a trained environmentalist, will be cdded to the Oconec Nuclecr Station staff.
This individual wi'l t
join tbc s:c. tion staff on or before April 15, 1974.
i.A.1.c Fish incirec ent inscection Although the operating license for Oconee I was issued on February 6, 1973, the environmental nonitoring program required by that license was not completely inplemented until June, 1973 The environmental technical specifications were not finalized until approximately two months before license time; consequently, sufficient manpower could not be employed, trained and allocated until June, 1973 The Directorate of Licensing environmental projector staff was advised of this delay in inplementation and did not express concern.
Consequently, the fish impinge-ment inspection program was implenented on June C, 1973 After implementation of the program, one weekly inspection was overlooked. This occurred during the first week of July, 1973 To insure that the weekly inspection of the intake screens and all other requirements of the non-radiological environmental technical specifications are met, our procedures are being set up to automatically remind personnel of dates of inspections.
The addition of an environmentalist will help.
l.A.2 Reportinc Recuirements Section 1.0 of the Oconee Non-Radiological Environmental Technical Goecifications states, in part, that the data obtained from the programs defined in the non-radiological environmental specifications shall be analyzed and compared with analytical predictions and preoperational data.
A report of the results of these programs sFall be forwarded to the Directorate of Licensing at the end of each six-month period or fr etion thereof, terminating on June 30 and December 31.
A report summarizing the results of the overall environmental surveillance and study programs shall be submitted 60 days following the third anniversary of the date that the last unit of the Oconee Nuclear Station is licensed to operate. We believe that these reports are the only reporting mechanisms provided for in the non-radiological environmental technical specifications. As was done in the semi-annual operating report for the period ending June 30, 1973, we would report any incident in which we were not in full compliance in the Semi-Annual Report covering the period in which the incident occurred.
We have also informally advised the Oconec RO inspector of any unusual condition involving the non-radiological environmental technical specifications.
