  • The Clean Air Act requires the U.S. Environmental Protection Agency (EPA) to identify and list the area source categories that represent 90 percent of the emissions of the urban air toxics associated with area sources and subject them to standards under the CAA (section 112(d)).
  • EPA has identified a total of 70 area source categories which represent 90 percent of the emissions of the air toxics.
  • Of these 70 area source categories, EPA promulgated 39 area source MACT standards by June 2008; the remaining area source standards are under development.
