ccepliance with the rule and there wculd be no change in accident doses to the envircrrent. Consequertly, the pretability of fires has not teen increased l
ard the post-firt radiological releases would not be greater than previously determined; not do the proposed exerptions otherwise affect radiological j
plant effluents. Therefore, the Conrission concludes that there are no sigrificant radiolcgical environnental irpacts associated with the proposed i

frvolve features located entirely within the restricted area as defired in I

no other environrental irpact. Therefore, the Consiission concludes that there are no significant nonradiological environrental inpacts associated with the grcrosed exerptiens.

Since we have cercluded that the envirorsental effects of the proposed action are not significart, any alternatives with equal or greater envircorettal inpacts need not be evaluated.
