UNITED STATES NUCLEAR REGULATORY COMMISSION SOUTHERN CALIFORNIA EDIS0N COMPANY, ET AL.
DOCKET NOS. 50-361 AND 50-362 NOTICE OF ENVIRONMENTAL ASSESSMENT AND FINDING OF 1
N0 SIGNIFICANT IMPACT s-The U. S. Nuclear Regulatory Comission (The Commission) is considering issuance of an exemption from the requirements of 10 CFR 70.24 to the Southern o
California Edison Company, San Diego Gas & Electric Company, The City of Anaheim, California, and the City of Riverside, California (the licensees).
The licensees hold Faci'ity Operating License Nos. NPF-10 and NPF-15, which
~
authorize operation of the San Onofre Nuclear Generating Station, Unit Nos. 2 and 3 (the facilities). These facilities are pressurized water reactors located in San Diego County, California.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action: The exemption from 10 CFR 70.24 would I
allow irradiated or unirradiated fuel assemblies to be handled and stored in the San Onofre 2 and 3 fuel handling building without having two criticality monitoring systems operable, provided that no more than one fuel ass'embly is out:ide an apprcved shipping container, storage rack, or fuel transfer tube at any time.

. j The Need for the Propossd Action:
The proposed exemption is needed to permit refueling operations at San Onofre 2 and 3 to be conducted without-installing
'b'ecriticalitydetectionsystemsspecifiedby10CFR70.24.
t Environmental Impacts of the Proposed Action:
There are no environmental impacts of the proposed action.
Criticality will be precluded by the use of geometric spacing in storing new and spent fuel storage racks and the restric--
tion'tnat no more than one fuel assembly shall be authorized to be outside an approved shipping container,].torage rack or the fuel transfer tube at any one time.
This is an acceptable alternative to redundant criticality detection systems.
Since the proposed change does not otherwise affect radiological plant eftiaants nor cause any significant occupational exposures, the Commission concludes that there are no significant radiological environmental impacts associated with this proposed exemption.
With regard to potential non-radiological impacts, the proposed exemption involves systems located entirely within the restricted area as defined in 10 CFR Part 20.
It does not affect non-radiological plant effluents and has no other environmental impact. Therefore, the Commission concludes that there are no'significant non-radiological environmental impacts associated with the proposed amendment.
Alternative to the Proposed Action: We have concluded that there is no measurable environmental impact associated with the proposed exemption.
The principal alternative would be to deny the requested exemption.
This would not reduce environmental impacts of plant operation.

- t Alternative Use of Resources: This action does not involve the use of resources not previously considered in connection with the " Final Environ-
~ ' '
mental Statement Related to the Proposed San Onofre Nuclear Generating Station Units 2 and 3" dated March 1973, the " Final Environmental Statement Related to the Operation of San Onofre Nuclear Generating Station Units 2 and 3", dated April 1981, and the Errata to the Final Environmental Statement dated June 1981.
Agencies and Persons Consulted:,The NRC staff reviewed the licensees' request and did not consult other agencies or persons.
1 FINDINGS OF NO SIGNIFICANT IMPACT l
The Commission has determined not to prepare an environmental impact

statement.for the proposed exemption.
Based upon the foregoing environmental assessment, we conclude that the propcsed action will not have a significant effect on the quality of the human environment.
1 For futher details with respect to this action, see the request for exemption dated March 27, 1984, which is available for public inspection at the Commission's Public Document Room, 1717 H Street, N.W., Washington, D.C.,
and at the San Clemente Branch Library, 242 Avenida Del Mar, San Clemente, California 92672.
Dated at Bethesda, Maryland this 17th day of September,1984.
