NESHAP for Inorganic Arsenic Emissions from Primary Copper Smelters (40 CFR Part 61, Subpart O) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Inorganic Arsenic Emissions from Primary Copper Smelters (40 CFR Part 61, Subpart O) apply to existing facilities and new facilities where the total arsenic charging rate for the copper converter department averaged over a 1-year period is greater than 75 kg/hr (165 lb/hr), as determined under 40 CFR 61.174(f). 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 61, Subpart O.
