a Industrial processes comprises chemical and allied product
manufacturing, metals processing, petroleum and related industries, and other
industrial processes; and solvent utilization, storage, and transport.
b Miscellaneous comprises nonroad gasoline- and diesel-powered
construction, industrial, lawn and garden, farm, light-commercial, logging
vehicles, and other nonroad sources; geogenic sources, catastrophic and
accidental releases, health services, cooling towers,
nontransportation-related fugitive dust, agriculture and forestry, structural
fires, agriculture fires, slash/prescribed burning, forest wildfires, 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 are not available, this data set only
contains the on road mobile sources.
