The paper discusses issues and emission estimation techniques for residential wood combustion (RWC). Nonattainment areas for PM-10 (particulate matter nominally 10 micrometers or less in size) are required to submit State Implementation Plans (SIPs) to the U.S. EPA that include emission inventories for RWC. The EPA also provides estimates of PM-10 emissions on a county-by-county basis for a national database. To improve RWC emission estimates, EPA will oversee three areas of development: (1) EPA will issue emission factors (for inclusion in Supplement D of EPA report AP-42) for woodstoves and fireplaces that will reflect new test data and thus provide more accurate estimates of RWC emissions--the emission factors will also be provided for stoves certified to EPA's Phase I emission limits, and emission factors for EPA-certified Phase II stoves will be based on stove data from actual Phase II stoves; (2) the Joint Emission Inventory Oversight Group (JEIOG) at EPA will improve guidance for inventories since existing guidance for the inventories is not adequate to meet the demands of the amended Clean Air Act; and (3) the JEIOG will develop a model for estimating RWC emissions for every U.S. county for entry into EPA's national Area and Mobile Source Subsystem (AMS) database.
