Establishing High State Standards for OWBs
There are two routes to establishing high standards for OWBs that reduce their environmental impact. The first route is to set high standards for their emissions, and the other is to establish stringent stack-height and set-back requirements. Washington state takes the former approach, and has established emission regulations for OWBs that exceed currently available technologies. Connecticut takes the later approach, requiring stacks to be taller than any near-by structure, set back deep on the property, and away from any adjacent properties. Both of these approaches create effective bans on OWBs within each state, and help to protect nearby residents in the few instances where they are permitted.
Outdoor Wood-fired Boiler Model Legislation for Municipalities
The Pennsylvania Department of Environmental Protection (PA DEP) offers a model ordinance for wood-fired outdoor-boilers for municipalities across the state. Many other states, however, offer model ordinances with stricter standards regarding setbacks and stack height for exhaust pipes. Here are a few examples from PA DEP, MI DEQ, and WI DNR.
