NESHAP for Nine Metal Fabrication and Area Finishing Source (40 CFR Part 63, Subpart XXXXXX) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP), for Nine Metal Fabrication and Finishing Area Sources (40 CFR Part 63, Subpart XXXXXX) apply to owners or operators of any existing or new metal fabrication and finishing facility that is an area source of hazardous air pollutant (HAP) emissions and uses or has the potential to emit metal fabrication or finishing metal HAP (MFHAP), defined to be the compounds of cadmium, chromium, lead, manganese, and nickel, or any of these metals in the elemental form with the exception of lead. The affected sources consist of several types of metal fabrication and finishing processes, including any abrasive blasting, metalworking (which includes machining, and dry grinding and dry polishing with machines), spray painting, and welding operations. New facilities include those that commenced construction or reconstruction after the date of proposal. 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. This information is being collected to assure compliance with 40 CFR Part 63, Subpart XXXXXX.
