KEY: R = revised.
a Fine particulate matter less than 10 microns. Data include
PM without condensibles.
b Industrial processes consists of chemical and allied
product manufacturing, metals processing, petroleum and related
industries, other industrial
processes; solvent utilization; and storage and transport.
c In 1985 there appears to
be a spike in miscellaneous emissions. This is likely due to a methodological
change, and the EPA does not change historical data when it changes its
methodology.
