RGATORY DoC'KE FI CONT UMN 18 1979 Docket No. 50-206 Mr. James H. Drake Vice President Southern California Edison Cdmpany 2244 Walnut Grove Avenue Post Office Box 800 Rosemead, California %91770
Dear Mr. Drake:
The.Commission has issued the enclosed Amendment No.1 to Provisional Operating License No. DPR-13 for the San Onofre Nuclear Generating Station, Unit No. 1 (SONGS, Unit 1).
The amendment consists of changes to the Technical Specifications in response to your request dated May 4, 1979.
The amendment increases the annual discharge limits of sulfate for calendar years 1979 and 1980, as specified in Subsection 2.2.2, "Added Process Chemicals" in the Appendix B Environmental Technical Specifi cations (ETS).
This ETS change will allow-temporary discharge of waste water containing sulfates from the startup flushing of SONGS, Units 2 and 3, via the SONGS, Unit 1 service water system. This method of disposal of the startup'water from SONGS, Units 2 and 3, would be utilized through 1980 when the circulating water system of these units is expected to be placed in service. The effluent containing sulfuric acid from Units 2 and 3 would be neutralized with sodium hydroxide to a pH of 6.0 to 9.0. This procedure would increase the sulfate concentration presently allowed in the Unit 1 ETS.
The current ETS limits the inaximum sulfate concentration in the discharge into the Pacific Ocean to 1.89 ppm. The natural occurring sulfate concentration of the Pacific Ocean near San Onofre is 2,650 ppm. Thus, the present ETS allows only a 0.07% increase over ambient sulfate concentration.' The proposed temporary inc-rease of the discharge of sulfate from Units 2 and3 ;via the Unit 1 discharge structure would allow a maximum sulfate concentration of 17.9 ppminto the Pacific Ocean or a 0.07%' increase over ambient sulfate concentration through 1980.
On January 1, 1981, the sulfate_ limits would revert back to the current ETS imits.

Mr. James H. Drake 2
JUN 1B 1979 The National Pollutant Discharge Elimination Systems (NPDE
) permit for San Onofre, Unit 1 issued by the California Regional Water' Quality Board (the Board) does not include a sulfate concentration limit. Nevertheless, we have discussed the licensee's proposal with the Board in San Diego. They indicated that the proposed 18-month higher sulfate concentration is environmentally insignificant and would not cause a noticeable impact to the Pacific Ocean. This is consistent with our previous, findings discussed in the San Onofre, Unit 1 Final Environmental Statement (FES),
that these proposed sulfate concentrations do not cause an environmental impact to the Pacific Ocean. Since the proposed 18-month increase of sulfate is temporary and still insignificant compared with the ambient concentrations, the assessment of sulfate discharge being environmentally insignificant in the FES for Unit 1 is still valid and acceptable.
Based on the above, we conclude that a temporary increase in sulfate concentration to permit the Units 2 and 3 startup flushing is acceptable as proposed.
We have evaluated the potential 'for environmental impact of plant operation in accordance with the enclosed amendment. The amendment applies only to temporarily increasing discharge of sulfate at environmentally insignificant concentrations. We have deternined' that the amendment does not authorize a change in effluent types or an increase in power level, and will not-result in any environmental impact. Having made this determination, we have further concluded that the amendment involves an action which is insignificant from the standpoint of environmental impact and pursuant to 10 CFR §51.5(d)(4) that an environmental impact statement or negative declaration and environmental impact.
appraisal need not be prepared in connection with the issuance of this amendment.
Since the amendment only permits a temporary increase in the concen tration of, sulfate in the effluent and is environmentally insignificant, it does not involve significant new safety information of a type not considered by a previous Commission safety review of the facility.
It does not involve a significant increase in the probability GU RNAM E.......................,,.
