As far as the stoves go themselves the EPA regulations only pertain to newly manufactured stoves. It doesn't concern older stoves. I don't recall when the first regs came out but something like a decade ago. They just set in place updated and more stricter ones. My understanding overall these regulations increase efficiency and reduce particulate emissions for very little cost but I really havent researched it that much. .
However some states and local laws ban their sale new or used and even their use is some cases. If you had 20 brand new stoves made in 1980 and lived in one of those states you couldn't sell them and the homeowner wouldn't be able to install it. The laws vary but you may not even be able to sell a house that has one in some states.
