There's a full list of options volume today.at CBOE.COM.

I don't think the open interest changes until the next day. A comparison from today to tomorrow should tell whether puts were transacted as open or to close positions.

Aug 12.5 put traded 160 contracts, but the open interest is listed as 88.
