You must (should) have the owners permission to condemn their tank or it could get ugly. When a tank does get condemned the threads are usually destroyed to prevent the installation of a valve. I'd always heard that they drill a hole into the side of the tank and "POOF" its condemned. I found out in my class that some people have actually threaded the hole, installed a plug, ground the head flush, and then placed a current VIP sticker over it and kept using it. UNBELIEVABLE!!! You may not always know whats under those stickers.
