§ 63.1459 What definitions apply to this subpart?

Terms used in this subpart are defined in the Clean Air Act, in § 63.2, and in this section as follows:

Anode refining department means the area at a primary copper smelter in which anode copper refining operations are performed. Emission sources in the anode refining department include anode refining furnaces and utility vessels.

Baghouse means a control device that collects particulate matter by filtering the gas stream through bags. A baghouse is also referred to as a “fabric filter.”

Bag leak detection system means a system that is capable of continuously monitoring relative particulate matter (dust) loadings in the exhaust of a baghouse in order to detect bag leaks and other upset conditions. A bag leak detection system includes, but is not limited to, an instrument that operates on triboelectric, light scattering, transmittance or other effect to continuously monitor relative particulate matter loadings.

Batch copper converter means a Peirce-Smith converter or Hoboken converter in which copper matte is oxidized to form blister copper by a process that is performed in discrete batches using a sequence of charging, blowing, skimming, and pouring.

Blowing means the operating mode for a batch copper converter during which air or oxygen-enriched air is injected into the molten converter bath.

Bypass stack means a device used for discharging combustion gases to avoid severe damage to the air pollution control device or other equipment and conduct planned maintenance safely in accordance with the work practice standard in § 63.1444(q). The use of a bypass stack during a performance test of a process or control device will invalidate the test.
