20555 Attention:
Mr. A. Schwencer, Chief Operating Reactors Branch No.1 Re: Oconee Nuclear Station Docket Nos.60-260 -270, -287
Dear Mr. Rusche:
Pursuant to 10CFR50, 550.90, an amendment to the Oconee Nuclear Station Non-Radiological Environmental Technical Specifications, Appendix B to Facility Operating Licenses DPR-38, -47, and -55 is requested.
This proposed change revises the method of control of station chemical effluents by instituting a chemical effluent monitoring program in lieu of the present chemical inventory program.
Replacement pages for the proposed Technical Specification 1.2 are attached, and an explanation and justification of this change is as follows:
In accordance with requirements of the present Technical Specification 1.2, station chemical inventories are maintained and chemical effluent release concentrations are determined by gross annual chemical usages.
Expected annual usage values of various chemicals were originally proposed in the Duke Power Company Supplement to Environmental Quality Features of Keowee-Toxaway Proj ect, of October, 1971 and were appraised by the NRC in the Oconee Final Environmental Statement of March 1972.
These values were adopted as limiting chemical usage values and remain as the present annual chemical release limits as stated in Table 1.2-1 of Technical Specification 1.2.
It is felt that these values are overly conservative since they indicate original expected chemical usagee and do not reflect state and federal limitatiens, nor do they rerlect an updated reasonable assessment of expected chemical effluents from Oconee Nuclear Station. Also, the chemical inventory method is considered an inaccurate method by which to base determination of chemical effluent concentration limits since large portions of certain chemicals may be utilized at the station but not enter the chemical effluent stream.

Mr. Benard C. Rusche Page 2 September 1, 1976 In order to alleviate the above problems, the proposed change to Technical Specification 1.2 replaces the chemical inventory require-ments with a program which provides for monitoring chemical effluence as they are released to the environment via the Low Level Radwaste System and the Wase.e Water Treatment System.
This proposal is consistent with monitoring presently performed at Oconee and require-
)
ments as indicated in the proposed Table 1.2-1 are consistent with present EPA requirements.
i It is felt that this proposed technical specification implements reasonable updated guidelines and limitations'for control of chemical effluents released from Oconee Nuclear Station.
Ve truly yours, AJE d.,/~v William O. Parker, Jr '
