State Air Quality Regulations
For permitting purposes, most states do not regulate wood burning systems that have less than 1Mbtu input and are using clean wood to generate needed heat. Messersmith systems are below this 1Mbtu input threshold.

Many states do not have specific information related to commercial wood burning systems on their websites; in those cases, we have linked to the state air agency home page. You may want to search at those locations for information about “air toxics” or “particle pollution.” On occasion, a county or city may have additional air quality requirements.
