NESHAP for Miscellaneous Metal Parts and Products (40 CFR part 63, subpart MMMM) (Final Rule)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Miscellaneous Metal Parts and Products were proposed on August 13, 2002, and promulgated on January 2, 2004. These regulations apply to both existing and new facilities with miscellaneous metal parts and products surface coating operations, and associated equipment or containers used for mixing, conveying, storage, or waste. New facilities include those that commenced construction or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart MMMM. In general, all NESHAP standards require initial notifications, 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.
