According to the State Summary of Emissions, in 2000, 100 facilities in Texas emitted into the
atmosphere more than 38,000 tons of particulate matter less than 10 microns, 794,000 tons of sulfur dioxide, 497,000 tons of nitrogen oxides, 76,000 tons
of nonmethane organic compounds -- including all VOCs -- and 224,000 tons of carbon monoxide. (FOOTNOTE: TCEQ, 2000 Point Source Emissions Summary Data, 2002).* Together, these 100 facilities produced more than twice as much criteria pollutants as the total produced by the remaining
8,300 facilities contained in the Point Source Emissions Database (TCEQ, 2000 Point Source Emissions Database, 2002.*
Many of these facilities were built before 1972, and
escaped major air pollution control requirements under the 1972 Texas Clean Air Act until recent changes enacted by the 1997, 1999 and 2001 Legislatures. These facilities are known as grandfathered facilities. Today, these facilities are
required to be permitted, albeit by a special class of permits. Most regulation of major stationary sources comes through air construction and operating permits. In 2001 the major manufacturing industries in Texas also released
more air toxics than any other state -- more than 85 million pounds in all (U.S. EPA, 2001 Toxics Release Inventory, Query run on TRI Explorer, October 2003).* When electric utilities and other non-manufacturing industries are
included, Texas facilities emitted more than 102 million pounds of toxics, ranking third behind Ohio and North Carolina
(U.S. EPA, 2001 Toxics Release Inventory, Query run on TRI Explorer, October 2003).
Because of these toxic emissions and criteria air pollutant levels, these industrial facilities, which the federal Clean Air
Act calls "major stationary sources," are often the focus of state and citizen efforts to reduce air pollution. This section
examines three categories of major- stationary- source air pollution in Texas: manufacturing, combustion, and mechanical facilities.
