SCBA tank "15 year life" Extension

There was just a discussion on this partially buried in diff thread. I just can't find it. I remember something about their permit being in limbo while a true 30yr life is discussed. Even if I'm wrong, the fee Digital Wave fee advertised to the public (especially after shipping them the tank) didn't seem to make economic sense for the individual. Maybe that's diff now, It's been a while since I looked the info up. 

Just something to think aboiut.
