Outdoor Wood-Fired Boilers


UPDATE! On June 8, 2013 Allegheny County gave final passage to stricter rules on OWBs in the county. Read the rule highlights here:

Outdoor Wood-Fired Boilers, or OWBs, are causing severe problems for many communities. These devices emit large amounts of particulate matter, and municipalities nationwide struggle with how to best regulate them. Almost 20% of the primary PM2.5 produced in Allegheny County comes from residential wood burning (learn more here, p. 12). On October 2, 2010, the PA DEP’s new OWB regulations came into effect.

GASP believes these state regulations are not strong enough to fully protect human health. Bear in mind that your own municipality can craft stronger laws than the state’s regulation, as Allegheny County did. Some areas, like the state of Washington, have banned OWBs altogether. Please contact GASP for more information if you wish to pursue this in your municipality.

Philip R.S. Johnson, a senior officer with the Heinz Endowments’ Environment Program, recently discussed here the limitations inherent in some traditional regulatory approaches to OWBs.
