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, promulgated on January 2, 2004, and amended on April 26, 2004, April 20, 2006, and December 22, 2006. The NESHAP is codified at 40 CFR Part 63, Subpart MMMM. This supporting statement addresses information collection activities that will be imposed by the NESHAP for Miscellaneous Metal Parts and Products, including activities added based on the residual risk and technology review (RTR) required under the Clean Air Act (CAA). The NESHAP for Miscellaneous Metal Parts and Products applies to each new and existing affected source of HAP emissions at facilities that are major sources and that perform 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 August 13, 2002. As part of the RTR for the NESHAP for Miscellaneous Metal Parts and Products, the Environmental Protection Agency (EPA) is not revising the emission limit requirements. The EPA is requiring periodic air emissions testing to measure organic HAP destruction or removal efficiency at the inlet and outlet of the add-on control device, or control device outlet concentration of organic HAP, once every five years for existing and new surface coating affected sources using the emission rate with add-on controls compliance option. The EPA is revising the startup, shutdown, and malfunction (SSM) provisions of the Maximum Achievable Control Technology (MACT) rule and requiring the use of electronic data reporting for future performance test data submittals, notifications, and reports. This information is being collected to assure compliance with 40 CFR Part 63, Subpart MMMM.
