I am dead against all regulations of private individuals, as is well known on this board. But, I think if regulations are going to be made, they need to be on a "complaints" basis. My outdoor gasifier smokes terrible for about 30 seconds on initial start up, then clears right out. I only burn wood or newspaper in it.
I think there needs to be setup a complaints area where neighbors can complain. Then, have a specific person or set of persons (OWB dealers come to mind) that can go out the the person's house and tell them that a complaint has been lodged and that they need to clean up there act. If the person expresses that they don't know what to do, then the gov't individual should be qualified and knowledgeable enough to show them ways to make their OWB's burn reasonably clean, such as dry wood, no garbage, etc..... This individual could throw in the fact that following these rules not only will make their neighbors happier, but also extend the life of their boiler. I also think that smoke regs should be set so that a "properly" operated OWB will not be outlawed... AKA: Neighbor's have to put up with it. We have neighbors all around us that have OWB's (Heatmor's and one other one that I don't know the Manufacturer of) and their burners do put out smoke, but visible smoke emissions never even leave their yard...
Then, if the individual doesn't clean up their act within 30 days, then you'd have to send the police out to shut down the system. By giving the person 30 days, they can try different things (like getting some drier wood, lining with firebrick, etc) to clean things up and not have to part with a substantial investment.
Once again, I don't agree with any of this, but if it has to be, I think this is the way it needs to be. I also think that it should apply to everything, indoor, outdoor, boiler, stove, or furnace........ Not pick on any particular product. And I DO NOT think that certs like EPA certs should be required, as some home-made contraptions burn very clean. Look at my stove. There's no way on earth that I can afford $60,000 to get my stove "certified" just to make some town yokel happy.
