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, typicall y of rotary barrel de sign, 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 ty pe of furnace. Group 1 furnace means a fur nace 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 des ign that melts, holds, or processes only clean charge and that performs no fluxing or performs fluxing using only nonreactive, non
- HAP - containing/non
- HAP generating 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 onl y clean charge, performs melting, holding, and f luxing 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 cas ting, extruding, rolling, scalping, forging, forming/stamping, cutting, and trimming operations and that do not contain paint or solid coatings. Uncoated/unpainted aluminum chips generated b y turning, boring, milling, and similarNESHAP for Secondary Aluminum (40 CFR part 63, subpart RRR)

DRAFT 10 / 7 /2010 Page 34 of 39 machining operations may b e clean charge if they

have been thermall y dried or treated b y 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 with in 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 whi ch 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.DRAFT 10 / 7 /2010 Page 35 of 39
