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; agriculture and forestry, health
services, cooling towers, fugitive dust; 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.
