OAR 330-135-0032: Woody Biomass Energy Technology Performance Requirements

(1) The woody biomass energy technology must be used for space or water heating or as a combined heat and power system. (2) The woody biomass boiler must have a lower heating value combustion efficiency rating of at least 80 percent. (3) The woody biomass energy technology must be located in an area that complies with DEQ particulate matter air quality standards, or if located in an area that does not comply with DEQ particulate matter air quality standards, must use pelletized woody biomass fuel or produce particulate matter at the same level as a system that uses pelletized woody biomass for fuel. (4) Woody biomass energy technology located in any area that exceeds the federal particulate matter (PM) standards, or has been designated as not meeting the federal standards at the time DEQ receives a notice to construct application for the woody biomass technology, must use pelletized woody biomass fuel or a fuel that produces particulate matter at the same level as a system that uses pelletized woody biomass for fuel.
