Attachment A. Definitions for subpart RRR MACT sources

Afterburner means an air pollution control device that uses controlled flame combustion to convert 

combustible materials to noncombustible gases; also known as an incinerator or a thermal oxidizer. 

Aluminum scrap means fragments of aluminum stock removed during manufacturing (i.e., machining), 

manufactured aluminum articles or parts rejected or discarded and useful only as material for 

reprocessing, and waste and discarded material made of aluminum.

Aluminum scrap shredder means a unit that crushes, grinds, or breaks aluminum scrap into a more 

uniform size prior to processing or charging to a scrap dryer/delacquering kiln/decoating kiln, or 

furnace. A bale breaker is not an aluminum scrap shredder. 

Clean charge means furnace charge materials, including molten aluminum; T-bar; sow; ingot; billet; pig; 

alloying elements; aluminum scrap known by the owner or operator to be entirely free of paints, 

coatings, and lubricants; uncoated/unpainted aluminum chips that have been thermally dried or treated 

by a centrifugal cleaner; aluminum scrap dried at 343 °C (650 °F) or higher; aluminum scrap 

delacquered/ decoated at 482 °C (900 °F) or higher, and runaround scrap

Cover flux means salt added to the surface of molten aluminum in a group 1 or group 2 furnace, without 

agitation of the molten aluminum, for the purpose of preventing oxidation.

Dross-only furnace means a furnace, typically of rotary barrel design, dedicated to the reclamation of 

aluminum from dross formed during melting, holding, fluxing, or alloying operations carried out in 

other process units. Dross and salt flux are the sole feedstocks to this type of furnace.

Group 1 furnace means a furnace of any design that melts, holds, or processes aluminum that contains 

paint, lubricants, coatings, or other foreign materials with or without reactive fluxing, or processes clean 

charge with reactive fluxing.

Group 2 furnace means a furnace of any design that melts, holds, or processes only clean charge and that 

performs no fluxing or performs fluxing using only nonreactive, non-HAP-containing/non-HAPgenerating gases or agents.

In-line fluxer means a device exterior to a furnace, located in a transfer line from a furnace, used to 

refine (flux) molten aluminum; also known as a flux box, degassing box, or demagging box.

Melting/holding furnace, or melter/holder, means a group 1 furnace that processes only clean charge, 

performs melting, holding, and fluxing functions, and does not transfer molten aluminum to or from 

another furnace.

Rotary dross cooler means a water-cooled rotary barrel device that accelerates cooling of dross. 

Runaround scrap means scrap materials generated on-site by aluminum casting, extruding, rolling, 

scalping, forging, forming/stamping, cutting, and trimming operations and that do not contain paint or 

solid coatings. Uncoated/unpainted aluminum chips generated by turning, boring, milling, and similar 
NESHAP for Secondary Aluminum (40 CFR part 63, subpart RRR)

DRAFT 7/13/2010 Page 33 of 38

machining operations may be clean charge if they have been thermally dried or treated by a centrifugal 

cleaner, but are not considered to be runaround scrap.

Scrap dryer/delacquering kiln/decoating kiln means a unit used primarily to remove various organic 

contaminants such as oil, paint, lacquer, ink, plastic, and/or rubber from aluminum scrap (including used 

beverage containers) prior to melting.

Secondary aluminum processing unit (SAPU): an existing SAPU means all existing group 1 furnaces 

and all existing in-line fluxers within a secondary aluminum production facility. Each existing group 1 

furnace or existing in-line fluxer is considered an emission unit within a secondary aluminum processing 

unit. A new SAPU means any combination of group 1 furnaces and in-line fluxers which are 

simultaneously constructed after February 11, 1999. Each of the group 1 furnaces or in-line fluxers 

within a new SAPU is considered an emission unit within that secondary aluminum processing unit.

Sidewell means an open well adjacent to the hearth of a furnace with connecting arches between the 

hearth and the open well through which molten aluminum is circulated between the hearth, where heat is 

applied by burners, and the open well, which is used for charging scrap and solid flux or salt to the 

furnace, injecting fluxing agents, and skimming dross.

Sweat furnace means a furnace used exclusively to reclaim aluminum from scrap that contains 

substantial quantities of iron by using heat to separate the low-melting point aluminum from the scrap 

while the higher melting-point iron remains in solid form.

Thermal chip dryer means a device that uses heat to evaporate water, oil, or oil/water mixtures from 

unpainted/uncoated aluminum chips.
