50-361/352 Mr. Robert Dietch Mr. D. W. Gilman Vice President Vice President -

Power Supply Southern California Edison Company San Diego Gas Electric Company 2244 Walnut Grove Avenue 101 Ash Street P. 0. Box 800 P. 0. Box 181 Rosemead, California, 91770 San Diego, California 92112

SUBJECT:

CLARIFICATION OF STAFF LETTER OF DECEMBER 17, 1980 REGARDING EFFECT OF EARTHQUAKES ON EMERGENCY RESPONSES AT SAN ONOFRE GENERATING STA14T71N.

This letter is to provide clarification of the subject staff request for additional information. The intent of that request is to assure that adequate considerationl has been given to the complicating factors which might be caused by earthquakes in the development of the emergency plans for your facility. We believe that planning for that eventuality should be part of your emergency plan in view of the relatively high frequency of severe earthquakes in California. Accordingly, -is indicated in our December 17, 1980 letter, you are requested to evaluate the effects earthquakes would have on your emergency response capability and include these considerations in your emergency plan. For purposes of this evaluation, as a planning basis you may assume that the plant site experiences earthquake effects no more severe than the Safe Shutdown Earthquake. While you need npt assume that a reactor accident occurs simultaneously with the earthquake event, you should include in your planning basis the consideration that the plant might have been adversely affected by the earthquake (e.g.

through failures or degradations in non-seismically qualified systems and components) and may, therefore, be more prone. to the potential for an incident that might result in off-site releases of radioactive material.

Specifically the following items should be considered in the evaluation of the effect of earthquakes on your emergency plan:

1. Ability to transport necessary personnel 'to the plant to cope with degraded modes of plant operation.

2.

Communication between the plant and outside agencies.

3. Ability to obtain damage estimates, both to the plant and to transportation/

communication facilities off-site. This information should be available to factor into the decision making process, including recormmendations to offsite authorities for protective actions after an earthquake.
