NOS-RADIOLOGICAL l'OSITORING 1.A.l.a Chemical DiscFnrre L'.its The canieu possible concentration of boric acid in the Keowcc River speci-fled in Section 1.2 of the Oconec non-Radiological Environ = ental Tcchnical Specificctions is 8.S x 10- ppm, a factor of 10 1ers than the natura21y occurring ccncentration of boron in the river.
This specificaticn could not be ret without severcly, and unduly, restricting operation of the station. A request for a change of this technical sp.cification li=it was 1
forwarded to the Directorate of Licensing on December 13, 1973. We have been inforred by the Directorate of Licensing that the proposed change has been revierc? and cpprovcd and should be issued very soon.
Until this change.in technical sp::*fications is i cued, discharges are restricted such that the resulting beric acid concentration in the Ecowee River is less than 1.0 ppm.
l This is appronizately 3 percent of the concentration she-in UASH-1249, United Staues Ato ic Energy Cec =ission. June, 1973, Page A-1, as guidance for drinking water supplies.
I.A.1.b Paste Unter Collection Easin Effluent pH Technical Specification 1.2b of Appendin B now states that all watcr dis-charged from the waste water collection basin shall have a pH between 6.0 and 8.5.
The pH of the effluent from the basin is not always representative of the actual discharge to the Keowee River because of the influence of other local drainage vaste streans.
Since the specification should apply to the actual discharge, we have proposed to the Directorate of Licensing that the specification be revised such that the actual discharge to the Keowce River shall have a pH between 6.0 and 8.5.
The pH shall be determined daily from a representative sample collected frem the combined effluent stren= before it discharges to the river.
Jn addition to this request for a chang; to the technical specification, a work order has been issued for an additional waste water handling and f
collection facility to double present capacity. The two basins will provide l

c separated capability for i.lection and discharge, plus in. 2ased capability fo: recirculttien to allow ct. cicht-hour turnover of volume.
This will permit better control of checi; cry prior to discharge.
As stated in the inr.pection report, incidents in uhich the effluent pH limir verc creccded were reported in the Oconce Nuclect Station Seui-Annual i
Rcpe: :.
Those incidents which cccurred after June 30, 1973, the end of the reporting period fer the first Seni-Annual Report, will be reported in the sccend Sc=1-Annuti report fer the period ending Deceeber 31, 1973.
I.A.1.c pH and Spacific Conductance ?!cnitoring The ucetc vater cellection bcsin efflucnt pH cnd cpecific conductance was not recorded for a total of 25 days during the period July 10 through Novenber 14, 1973.
On thece days, the vaste water collection basin was either drained or there was no discharge.
It is now required that an ap-propriate entry be nade on the daily che imtry report to reflect the status of the collection bcsin uhen no sample is available or required.
I.A.1.d Dieselved Oxvren Mencurerents The statement contained in RO Inspection Report 50-269/73-13 (DETAILS III, Paragraph 8) that dissolved oxygen measurements were not made for a total of five vecks during the period June 15, 1973 through August 17, 1973, is incorrect. Ucekly dissolved exygen measurem nts were made at the three specified locations after the monitoring program was initiated on June 8, 1973, except during the weeks of July 1, July 8, July 29, August 19, cnd September 9, 1973.
Results of the weekly monitoring program for the month of June 1973 have been reported in Table 1.3.1-10A of the Oconee Nuclear Station Semi-Innual Report for the period end ng June 30, 1973.
Arrangenents have been made for operation of Keowee Hydroelectric Station as required to facilitate the proper sampling of the Keewee tailrace.
To assist in the administration and execution of non-radiologiccl environ-cental monitoring cnd surveillence procedures, another person, a trained envirennentalist, will be added to the Oconec Nuclear Station staff.
This individual vill join the station staff on or before April 15, 1974.

.ru etion

The fish impingement inspection program, as described in Section 1.4 of the Oconce Semi-Annual Report for the period ending June 30, 1973, was imple-tented on June 8, 1973. After inple=entction of the program, one weekly inspection war overlocl-d.
This occurred drring thc first wech of July, 1973.
To insure that the vechly inspection of the intake screens and all other requiretents of the ncn-radiological environ =cntcl technical specifi-cations cre tct, our procedures cre being set up to automaticclly remind personncl of dates of inspections.
The additica of an environmentalist i
will help.
I.A.2 Erecrtine Eetuirerents Section 1.0 of thc Oconec I;cn-Radiological Environmental Technical Tpecifi-cctienc states, in pcrt, that tic dcta obtained frem the progrces define.d in the no;.-radiological environ =cntal specifications shc11 be analyced and compared with analyticcl predictions and preoperational data. A report of the results of these programs shall be forwarded to the Directorate of Licensing at ne end of each six-conth period or friction thereof, terminating on June 30 and Dece=bor 31.
A report summaricing the results of the overall environ = ental surveillance and study progra=s shall be subcitted 60 days following the third anniversary of the date the last unit of the Ocenee 1;uclear Statien is licensed to operate.
These reports are the only reporting mechanises provided for in the non-radiclogical 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 co=pliante in the Semi-Annual Report covering the period in which the incident occurred.
We have also informally advised the Oconee R0 inspector of any unusual conditic, involving the non-radiological environmental technical specifications.
