Dear Mr. Withers:

SU3 JECT: EFFECT OF VOLCANIC ERUPTION ON EMERGENCY RESPONSES AT TROJAN NUCLEAR PLANT As part of our continuing review-of the Trojan Site Emergency Plan dated

~

~ ~

May 1930, and in consideration of the strong possibility of continued volcanic activity at Mount St. Helens, we request that the Trojan Site Er.ergency Plan be revised to address volcanic activity.

In particular, the evacuation time estimates should be revised to consider adverse condi-tions resulting from volcanic activity such as severe ashfall, mudflows, floeds or landslides; the procedures used to determine the protective actions recommended to offsite authorities should be revised to incor-porate consideration of volcanic activity; and the impact of volcanic activity on the augmentation of site emergency personnel and offsite emergency assistance and transit to and among emergency response facili-ties and ccmmunication with offsite authorities should be addressed.

The revisions to the protective action determination methods and evacuation time estimates should be revised in coordination with offsite officials responsible for protective action decisionmaking and implementation.

The response to this concern should be incorporated in a revised Trojan Site Emergency Plan submitted in accordance with the provisions of the revised 10 CFR Part 50 of the Cmission's regulations.
