This link below might help a little bit with AST. It's from 2005, but it will give you a list of the active/inactive chapters at that point. I think the only inactive chapter that's been re-installed is Iota (Emporia State University in Kansas).
Of course, other chapters may have been opened/closed in addition to those listed. I can't look through this right now, but I figured this would help if you got to it before I did.
