NESHAP for Halogenated Solvent Cleaners/Halogenated Hazardous Air Pollutants (40 CFR Part 63, Subpart T) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Halogenated Solvent Cleaners/Halogenated Hazardous Air Pollutants were proposed on November 29, 1993, and promulgated on December 2, 1994. The NESHAP was amended on the following dates: June 5, 1995; December 11, 1998; July 13, 1999; August 19, 1999; and May 3, 2007. These regulations apply to each individual batch vapor, in-line vapor, in-line cold, and batch cold solvent cleaning machine that uses any solvent containing methylene chloride, perchloroethylene, 1, 1, 1-trichloroethane, trichloroethylene, carbon tetrachloride, chloroform, or any combination of these halogenated HAP solvents, in a total concentration greater than 5 percent by weight, as a cleaning and/or drying agent. New facilities include those that commenced construction or reconstruction on or after December 2, 1994. This information is being collected to assure compliance with 40 CFR Part 63, Subpart T. In general, all NESHAP standards require initial notification reports, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NESHAP.
