SOURCE CATEGORIES--Table of Contents

Subpart QQQ_National Emission Standards for Hazardous Air Pollutants for

Primary Copper Smelting

Sec. 63.1459 What definitions apply to this subpart?

Terms used in this subpart are defined in the Clean Air Act, in

Sec. 63.2, and in this section as follows:

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.

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.''

Batch copper converter means a Pierce-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.

Capture system means the collection of components used to capture

gases and fumes released from one or more emission points, and to convey

the captured gases and fumes to a control device. A capture system may

include,

[[Page 49]]

but is not limited to, the following components as applicable to a given

capture system design: duct intake devices, hoods, enclosures, ductwork,

dampers, manifolds, plenums, and fans.

Charging means the operating mode for a batch copper converter

during which molten or solid material is added into the vessel.

Control device means the air pollution control equipment used to

collect particulate matter emissions. Examples of such equipment

include, but are not limited to, a baghouse, an electrostatic

precipitator, and a wet scrubber.

Copper concentrate dryer means a vessel in which copper concentrates

are heated in the presence of air to reduce the moisture content of the

material. Supplemental copper-bearing feed materials and fluxes may be

added or mixed with the copper concentrates fed to a copper concentrate

dryer.

Copper converter department means the area at a primary copper

smelter in which the copper converters are located.

Copper matte means a material predominately composed of copper and

iron sulfides produced by smelting copper ore concentrates.

Deviation means any instance in which an affected source subject to

this subpart or an owner or operator of such a source fails to meet any

of the following:

(1) Any requirement or obligation established by this subpart

including, but not limited to, any emission limitation (including any

operating limit) or work practice standard;

(2) Any term or condition that is adopted to implement an applicable

requirement in this subpart and that is included in the operating permit

for any affected source required to obtain such a permit; or

(3) Any emission limitation (including any operating limit) or work

practice standard in this subpart during startup, shutdown, or

malfunction, regardless whether or not such failure is permitted by this

subpart.

Emission limitation means any emission limit, opacity limit,

operating limit, or visible emission limit.

Fugitive dust material means copper concentrate, dross, reverts,

slag, speiss, or other solid copper-bearing materials.

Fugitive dust source means a stationary source of particulate matter

emissions resulting from the handling, storage, transfer, or other

management of fugitive dust materials where the source is not associated

with a specific process, process vent, or stack. Examples of a fugitive

dust source include, but are not limited to, on-site roadways used by

trucks transporting copper concentrate, unloading of materials from

trucks or railcars, outdoor material storage piles, and transfer of

material to hoppers and bins.

Holding means the operating mode for a batch copper converter during

which the molten bath is maintained in the vessel but no blowing is

performed nor is material added into or removed from the vessel.

Opacity means the degree to which emissions reduce the transmission

of light.

Particulate matter means any finely divided solid or liquid

material, other than uncombined water, as measured by the specific

reference method.

Pouring means the operating mode for a batch copper converter during

which molten copper is removed from the vessel.

Primary copper smelter means any installation or any intermediate

process engaged in the production of copper from copper sulfide ore

concentrates through the use of pyrometallurgical techniques.

Responsible official means responsible official as defined in 40 CFR

70.2.

Skimming means the batch copper converter operating mode during

which molten slag is removed from the vessel.

Slag cleaning vessel means a vessel that receives molten copper-

bearing material and the predominant use of the vessel is to separate

this material into molten copper matte and slag layers.

Smelting furnace means a furnace, reactor, or other type of vessel

in which copper ore concentrate and fluxes are melted to form a molten

mass of material containing copper matte and slag. Other copper-bearing

materials may also be charged to the smelting furnace.

[[Page 50]]

Work practice standard means any design, equipment, work practice,

or operational standard, or combination thereof, that is promulgated

pursuant to section 112(h) of the Clean Air Act.
