Aside from the R12 that actually went all the way to the ozone layer, and wreaked havoc on it. Take a good look at the maps of the ozone layer over time. Fortunately, it was able to recover once we almost completely stopped dumping CFC's up there.

From the maps I saw there was a hole which develops and reseals virtually every year on a cycle, but I can't find those maps just now. At any rate, this is getting close to a political discussion. I think we're saying:
If you vent it, nobody will notice. If you are concerned about the environmental damage (which is a valid concern, in my opinion) then there were several options put forth.
Sorry to be controversial, I probably could have skipped a few lines there...
Who knew a hole in the ozone could be political?
I did some more checking around, and actually found a few places that still have the equipment. Unfortunately, that means getting the truck TO the shop... which means turning a blind eye to one set of rules to follow another.
