If you look at the map of that plume, you see that it was most heavily concentrated in areas miles to the east.
Ironically my neighborhood is right off of 72 and 93 and is completely white on the map.

Note that this Wikipedia article isn't up to date and has some biased editing. For example Rocky flats refuge has been open to the public for a couple of years now. The article has the typical antinuclear activist tactic of FUD.
As a person who has to deal with climate change related incidents like the fire yesterday, I have huge animosity towards anti-nuclear activists.
The same people who have been protesting everything nuclear for decades are the ones complaining about climate change now without seeming to understand that all of the Western world would be like France now if not for them. The fire we are ringing our hands about potentially causing contamination probably would not have happened if not for these activists destroying the reputation of nuclear power over several decades.
