Rule Summary

The Hazardous Air Pollutants (HAP) listed in Section 112(b)(1) of the Clean Air Act emitted by aerospace facilities that are covered by this final rule include:

  • chromium,
  • cadmium,
  • methylene chloride,
  • toluene,
  • xylene,
  • methyl ethyl ketone,
  • ethylene glycol and
  • glycol ethers.

This National Emission Standards for Hazardous Air Pollutants (NESHAP) rule will reduce nationwide emissions of HAP from at least 2,869 major source aerospace manufacturing and rework facilities by approximately 112,600 Mg (123,700tons).
