NESHAP for Ferroalloys Production: Ferromanganese and Silicomanganese (40 CFR Part 63, Subpart XXX) (Renewal)

The NESHAP for Ferroalloys Production: Ferromanganese and Silicomanganese applies to new and existing ferroalloy production facilities that manufacture ferromanganese and silicomanganese, and that are either major sources of hazardous air pollutant (HAP) emissions or are co-located at major sources of HAPs. The following affected facilities at ferroalloy production plants are subject to this NESHAP rule: submerged arc furnaces; metal oxygen refining processes; crushing and screening operations; and fugitive dust sources. 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 with 40 CFR Part 63, Subpart XXX.
