Abstract: The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Primary Magnesium Refining (40 CFR Part 63, Subpart TTTTT) were proposed on January 22, 2003; promulgated on October 10, 2003; and most recently amended on November 19, 2020. These regulations apply to both existing and new facilities that perform primary magnesium refining where the total hazardous air pollutants (HAPs) emitted are greater than, or equal to, 10 tons per year for each HAP, or where the total HAPs emitted are greater than, or equal to, 25 tons per year of any combination of HAPs. 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 TTTTT. 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.
