DOCKET NOS. 50-361 AND 50-362 SAN ONGFRE NUCLEAR GENERATING STATION, UNITS 2 AND 3 ENVIRONMENTAL ASSESSMENT AND FINDING 0F N0 SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Commission (the Commission) is considering issuance of amendments to Facility Operating License No. NPF-10 and Facility Operating License No. NPF-15 issued to Southern California Edison Company, San Diego Gas and Electric Company, the City of Riverside California and the City of Anaheim, California (the licensees), for operation of San Onofre Nuclear Generating Station, Units 2 and 3, located in San Diego County, California.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:
The proposed amendments would revise Technical Specification 3/4.8.2.1, "DC Sources, " to increase the interval for the 18 month surveillance tests to at least once per refueling interval, which is defined as 24 months, in support of the nominal 24 month fuel cycle.
The Need for the Proposed Action:
The proposed amendments are required to prevent unnecessary plant shutdowns to per#orm a surveillance test which cannot be performed during plant operation.
Environmental Impacts of the Proposed Action:
The proposed action would not involve a significant change in the probability or consequences of any accident previously evaluated, nor does it involve a new or different kind of accident. Consequently, any radiological releases resulting from an accident would not be significantly greater than previously determined. The proposed amendments do not otherwise affect routine 8906200129 890621 ~

- radiological plant effluents. Therefore, the Commission concludes that there g
are no significant radiological environmental impacts associated with the 1
proposed amendments. The Commission also concludes that the proposed action will not result in a significant increase in individual or cumulative occupa-tional radiation exposure.
With regard to nonradiological impacts, the proposed amendments do not affect nonradiological plant effluents'and have no other environmental impact.
Therefore, the Commission concludes that there are no significant nonradio-logical environmental impacts associated with'the proposed amendments.
The Notice of Consideration of Issuance of Amendment and Opportunity for Hearing in connection with this action was published in the Federal Register on February 14, 1989 (54 FR 6791). No request for hearing or petition for leave to intervene was filed following this notice.
Alternatives to the Proposed Action:
Because the Commission has concluded that there are no significant environmental impacts associated with the proposed action, there is no net 1 t-examine alternatives to the proposed action.
Alternative Use of Resources:
This action does not involve the use of resources not previously considered in connection with the Final Environmental Statement related to operation of San Onofre Nuclear Generating Station, Unit 2 and 3, dated April 1981 and its Errata dated June 1981.
Agencies and Persons Consulted:
The NRC staff has reviewed the licensee's request that supports the proposed amendments.
The NRC staff did not consult other agencies or persons.
l
- FINDING OF NO SIGNIFICANT IMPACT The Comission has determined not to prepare an environmental impact statement for the proposed amendments.
Based upon the foregoing environmental assessment, the Commission concludes that the proposed action will not have a significant effect on the quality of the human environment.
For further details with respect to this action, see the application for amendments dated December 29, 1988, which is available for public inspection at the Comission's Public Document Room, 2120 L Street NW., Washington, DC 20555, and at the General Library, Universiv of California, P.O.
