One volcano trumps everyone's lifetime of wood stove emissions.

The impact is zero, there is none! HS

I wouldn't say that, HS...it is a combustion process and no combustion process is 100% efficient.

One thing that keeps the EPA off our backs is the relatively small population that heats by wood. That's my opinion, not fact.
However, as I wrote previously...sooner or later, they will stir the pot!

The conservation of energy, net carbon, etc. is only part of the environmental impact of burning firewood. That part is largely beyond our control I think. It's going to happen no matter what by some process or other.

It's how that process happens that is the real environmental impact on human health. Sitting next to a rotting log all day, compared to breathing smoke all day, are not equal. Burning the wood accelerates the process, which in turn results in more concentrated and different chemical results in a given length of time.

So, now matter how clean a stove burns, saying there is no net change is beside the point of what actually matters for human health.

I think Roy is correct in saying because the number of wood burners is relatively small, the scope of the problem is small too. For example, if the majority of homes in a city or town were heated using poor stoves, poor wood fuels, or poor combustion practices, the result would not be something you would enjoy and it would have an impact on your health.

The small number of wood burners is indeed important, but even more important to EPA, and your local Air Pollution Control authority, is the status of the air quality in your particular state/region/area. If your area is in attainment, there is much less pressure to reduce emissions, and NSPS (New Source Performance Standards) will require new stoves and furnaces to meet strict standards. In non attainment areas, there is severe pressure to reduce all emissions, not only for new sources but for all existing sources...maybe up to the point of outlawing fireplaces, old stoves, smoke, etc.

5 million+ acres of forest burn every year,and that's OK,but we just try to keep warm,and get attacked.

Is it safe to say that in the not so distant future, wood burning in the home and the open air burning of wood will be targeted for EPA review? Ken Sweet

Google " EPA Chicken Alaska" and see what they did this year because of a possible water quality issue. If something isn't done to stop them,they will be going door to door Killing people for burning wood!

Open air burning has been regulated very early on by EPA. It was their position that open burning, auto and industrial emissions were the biggest culprits in air pollution, so open burning has been regulated to one extent or another for probably 40 years. There are exceptions, e.g., areas where there is no trash pickup, health emergencies, supervised crop burning and forest management, but by and large it is prohibited. Wood burning in the home is in a sense regulated, in that new wood stoves must meet certain emission requirements known as NSPS (New Source Performance Standards).

Existing homes and stoves are largely unregulated in areas with clean air. New units meeting NSPS standards will keep new emissions down, and hopefully, old stoves will eventually die and be replaced by new cleaner ones. Where existing units come under regulation is where the air quality does not meet current standards, then states must take measures to reduce pollution in an effort to meet the standards. States may be forced to prohibit wood burning, or at least limit it to units with catalytic converters and even regulate any visible smoke from chimneys. Limits and regulations can, and do vary, depending on the authority, the location and the severity of the non attainment.

We do not regulate fireplaces and old wood stoves in this state, at least they didn't when I was in the business; however open burning has always been prohibited here since the early days of regulation. Such things as open burning of trash, metal salvaging, disposal of wastes, etc fell under the regulations. We also had a prohibition on smoke emissions; smoke in excess of 20% opacity was a violation and could result in fines.

To answer your question, then, I think the answer is that they already target these things to one degree or another, depending on where you live and the quality of your air. It may well be that if your air is clean, they may never target existing wood burning stoves, or at least not for a long time. Targeting private individuals and their homes has always been touchy politically, and states shy away from this as much as possible, particularly when there is no apparent problem with it. Now if the air is visibly polluted, folks are complaining and a nuisance is created, there can be a lot of pressure.
