Re[2]: Liquid waste tank decommissioning!

     Another option is polyurathane foam.  It set up as a light-weight 
     solid.  Great for gloveboxes that need to be retired.

Another option that was used at ORNL was grouting in place. The tank was
just filled with a low-density grout mixture and all aboveground
penetrations were cut off to below ground, then the tank was filled over. If
you don't HAVE to remove the tank, it's another option.
