Data include PM without condensiblebIndustrial processes consists <strong>of</strong> chemical and allied product manufacturing, metals processing, petroleum and related industries, other industrialprocesses; solvent utilization; and storage and transport.cIn 1985 there appears to be a spike in Miscellaneous emissions. This is likely due to a methodological change, and the EPA does not change historicaldata when it changes its methodology.NOTEDetails may not add up to totals due to rounding in the source.SOURCEU.S. Environmental Protection Agency, Clearinghouse for Inventories and Emissions Factors (CHIEF), Current Emission Trends Summaries, available athttp://www.epa.gov/ttn/chief/trends/index.html as <strong>of</strong> October 2009, and personal communication, February 2011.
