MADISON, Wis.—An increase in the use of outdoor wood-fired boilers in Wisconsin is raising concerns about the effect of wood smoke on air quality. A new fact sheet from the UW-Extension Solid and Hazardous Waste Education Center (SHWEC) discusses some of the health and air quality issues raised by wood heating, and suggests steps you can take to minimize the impact of wood smoke in your community.

“Wood as a Heating Fuel: Air Quality Issues and Options” is available for downloading on the SHWEC web site at http://www3.uwm.edu/Dept/shwec/publications/cabinet/p2/Woodburning2-06.pdf .

In 2002, the Wisconsin Department of Natural Resources (DNR) began statewide monitoring for levels of fine particulates, such as those produced when coal, oil, diesel or wood is burned. Using wood as a residential heating fuel contributes more to fine particle pollution than any other type of heating fuel.

When outdoor wood-fired boilers are used in urban and suburban areas, excessive amounts of smoke and low chimney heights can create serious health concerns for neighbors. Currently, outdoor wood-fired boilers are not required to meet EPA emission standards, and the Wisconsin DNR has limited jurisdiction over residential wood burning. However, Wisconsin communities may enact ordinances that control outdoor burning and outdoor wood-fired boilers.

As the use of wood as a home heating fuel increases, Wisconsin communities will need to address its impact on air quality and public health. This new fact sheet provides a research-based starting point for discussion of the issues involved.
