It's inescapable that all wood-burning for any purpose would eventually be roped in, if EPA is allowed to continue to regulate CO2 as a greenjhouse gas.
A little history on this, the EPA under Bush fought having to do it, hardcore environmentalist globull warming advocates took them to court and eventually the courts forced the Bush EPA to accept the task under the Clean Air Act. The only real way to cure this is for Congress to amend the CAA to at least exempt household emissions if not just remove the CO2-as-greenhouse-gas issue from its purview.
