NESHAP for Iron and Steel Foundries (40 CFR part 63, subpart ZZZZZ) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Iron and Steel Foundries Area Sources (40 CFR Part 63, Subpart ZZZZZ) apply to both new and existing iron and/or steel foundries that are an area source of hazardous air pollutants (HAP) emissions. There are different requirements for foundries based on size. Existing foundries with an annual metal melt production greater that 20,000 tons and new foundries with an annual melt capacity of 10,000 tons are classified as large foundries. Existing foundries with an annual metal melt capacity of 10,000 tons or less are classified as small foundries. Research and development facilities are not covered by the rule. New facilities include those that commenced construction, modification 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 ZZZZZ.
