, Gentlemen:.
The Nuclear Regulatory Comission has issued Amendment Nos. 9, 9, and 6 to License Nos. DPR-38, DPR-47, and DPR-55 (copies enclosed) 4 I
for the Oconee Nuclear Station Units 1, 2, and 3, respectively,
{
based on Change Nos.19,14, and 6 to the Technical Specifications.
)
i The amendments provide for administrative procedure changes of the
~
environmental surveillance program to convert to metric measure-a ments, change fmm variable sagling station locations to fixed locaticns, redesignate sagling locations, and clarify sampling frequency requirements already specified in the special studies specification requirements in Sections 1.3.1,1.3.4,1.3.5, and 1.6 of Appendix B Technical Specifications as follow.;-
[
/
Technical Specification 1.3.1.A - Water Quality 1.
To incorporate use of meters in lieu of feet for depth measum-ment of temperature, dissolved oxygen and biochemical oxylen demand to effect cogatibility with other investigations.
Technical Specification 1.3.4 - Phytoplankton-Iooplankton Receivina j
I 2.
Water Studies
_.To substitute two fixed monitoring stations in the themal plume in place of the existing two station points at tshich the plume-
. surface temperature is 0.9 and 0.5 of. the:tenperature excess of,
the discharge over ambient surface temperature to pmvide.nore reliable data.

Technical Specification 1.6_- Plume Mapping for Temperature and
' Dissolved Oxygen.
To delete requirement for sampling on a seasonal basis in conjunc-tion with themal plume mapping for tegerature and di:; solved oxygen special studies because sampling will not be strictly on a seasonal basis. Specific temperature, acreage and dissolved oxygen conditions are already specified for these studies in the specifications.
These changes are in connection with your request dated May 23, 1975.
The Comission has evaluated the pbtential impact of the operating plant in accordance with the amendments and has concluded that there will be no change in effluent types or total amounts nor an increase in power level, as previously evaluated in the Final Environmental Statement for Oconce Nuclear Station Units 1, 2, and 3 dated March 1972 andjwill not result in any significant environmental impact.
The amendments revise administrative procedures and controls only and should provide more reliable data and result in a more effective monitoring program at Oconee Nuclear Station. Having made this
-S, determination, the Comission has further concluded, pursuant to 10 CFR 51.5(d)(4), that an environmental statement, negative declaration or environmental impact appraisal need not be prepared in connection with the issuance of these amendments.
The amendments address administrative processes only and do not in-volve new safsty information of a type not ' considered by a previous _
Comission review of the facility.
It does not involve a significant increase in the probability or consequences of an accident, does not involve a significant decrease in a safety margin of the facility, and -
therefore does not involve significant nazard considerations. The Commission has also concluded that there is reasonable assurance that health and safety of 1.he public will not be endangeeed by the proposed action.
Sincerely.
