a Fine particulate matter less than 10 microns.
b Industrial processes comprises chemical and allied product
manufacturing, metals processing, petroleum and related industries, and other
industrial processes; solvent utilization; and storage and transport.
c Miscellaneous comprises nonroad gasoline- and diesel-powered
construction, industrial, lawn and garden, farm, light-commercial, logging
vehicles and other non-road sources; geogenic sources; agriculture and
forestry, cooling towers, nontransportation-related fugitive dust, wildfires,
managed burning, and other combustion sources that could not be accurately
allocated to specific source categories.
NOTE
Previous edition's data include all on road mobile sources and
some nonroad mobile sources, since EPA changed the methodology to estimate
emissions, the details of the data is not available, this data set only
contains the on road mobile sources.
