This action promulgates amendments to the ``National Emission Standards for Hazardous Air Pollutants: Halogenated Solvent Cleaning'' originally promulgated on December 2, 1994. These amendments to the rule were proposed on August 19, 1999. Today's action finalizes compliance options for continuous web cleaning machines, as well as amendments to the national emission standards for hazardous air pollutants (NESHAP) that apply to steam-heated vapor cleaning machines and to cleaning machines used to clean transformers. The EPA is finalizing these amendments to ensure that all owners or operators of solvent cleaning machines have appropriate and attainable requirements for their cleaning machines.
