National Emission Standards for Aerospace Manufacturing and Rework Facilities

On September 1, 1995, we promulgated the National Emission Standards for Aerospace Manufacturing and Rework Facilities. On January 24, 2000, we proposed to amend the standards to include a separate emission limit for exterior primers used for large commercial aircraft at existing facilities that produce fully assembled, large commercial aircraft. This action finalizes those proposed amendments. In addition, we are making a minor correction to the monitoring requirements section of the aerospace emission standards. The amendment helps correct regulatory language that erroneously made reference to a list of requirements for initial compliance demonstrations when using incinerators and carbon adsorbers.
