Is this column load bearing?
Several things suggest that it's not load bearing:


The fact that it's at the end of a "pony wall". This is likely a horizontal support post that wouldn't be present if not for the wall.
The wording "to ceiling". This suggests no structural integration with the roof framing or any supporting member.
The lack of blocking or other load-transfer notes in the floor framing layout.


Some things that would seal the deal:


Footing layout showing no supporting structure at this location, and...
Main floor truss diagrams showing no concentrated load below the post. 


With what's presented here I can only be about 98% certain. If you want more than that, consult a local professional.
