I think the radius of the evacuation zone should be up to the issuer to justify. If you want a 1-mile zone it seems that you should be able to articulate why or else it should just get denied. However, it seems that wikipedia et al don't seem to have a citation as to how 1 mile was picked so it's hard to say if a smaller or larger zone should've been done. Edit: Found a chart from Ohio.gov [1] showing impact areas. It does seem to be much smaller than 1mi. > Since hot smoke travels upwards, I don't know what making the zone wider would have accomplished. I mean if hot air only went up the Earth would have no atmosphere after a sunny day.
