Cigarette smoking IS allowed at Point Beach in the designated smoking areas. There are two of them inside the fence, and one by the training building. They are all located outside but they do have the little bus stop style shelters.
I think that smoking in the parking lot here is officially against the rules, but I've seen lots of people doing it, so I don't think that policy is being strictly enforced at this time. Of course all it takes is one person to complain to change that in a hurry.
I remember working an outage at Plant Vogtle in spring of '99, there was one designated smoking area on site, and it was monitored at all times by security guards who would watch to make sure nobody was taking too many cigarette breaks. I think we were allowed three 15 minute breaks per shift... and the walk to and from THE designated smoking area took about 12 min 'round trip. This site also had "Designated Eating and Drinking Areas" too, which I haven't seen anywhere before, or since.
