"Existing lead emission unit" means a lead emission unit in
				existence before January 1, 2015 at a nonferrous metal production
				facility.
"Housekeeping activities" means regular cleaning or maintenance
				activities conducted to reduce fugitive emissions from production areas.
"Induction furnace" means an electrical furnace used for
				heating metal by electromagnetic induction.
"Lead" means elemental lead or alloys in which the predominant

				component).
"Lead-bearing scrap" or "lead-containing material" or
				"lead-containing metal" or "lead-containing wastes" or "lead particulate" means
				scrap or material or metal or wastes or particulate with a lead content equal
				to or greater than 5 mg/l as measured by EPA Method 1311, incorporated by
				reference in Section
				226.120.
"Lead emission unit" means any process that emits lead,
				including, but not limited to, battery breaking areas; material handling areas;
				dryers and dryer areas; channel furnaces and channel furnace areas; coreless
				furnaces and coreless furnace areas; reverberatory furnaces and reverberatory
				furnace areas; rotary furnaces and rotary furnace areas; agglomerating furnaces
				and agglomerating furnace areas; kettles and casting areas; lead taps, slag
				taps, and molds during tapping; and areas where dust from fabric filters,
				sweepings, or used fabric filters are processed.
"Lead kettle" means a vessel that is heated from below and is
				used for the purpose of melting refined lead.
"Lead tap" means the pouring hole though which molten lead
				flows from a kettle or furnace.
"Leak detection system" means an instrument that is capable of
				monitoring relative particulate matter (dust) loadings in the exhaust of a
				particulate control in order to detect leaks in the particulate control. A leak
				detection system includes, but is not limited to, an instrument that operates
				on triboelectric, light scattering, transmittance, or other effect to monitor
				relative particulate matter loadings.
"Materials handling area" means any area in which
				lead-containing materials (including, but not limited to, broken battery
				components, flue dust, and dross) are handled in between process steps. These
				areas may include, but are not limited to, areas in which lead-bearing scrap,
				lead-containing materials, lead-containing metal, or lead-containing wastes are
				prepared.
"Materials storage area" means any area in which
				lead-containing materials (including, but not limited to, broken battery
				components, flue dust, and dross) are stored in between process steps. These
				areas may include, but are not limited to, areas in which lead-bearing scrap,
				lead-containing materials, lead-containing metal, or lead-containing wastes are
				stored in open piles, bins, or tubs.
"Mold cooling" means the process of cooling a mold containing
				hot metal by direct contact of the mold, but not the hot metal itself, with
				cooling water or other liquids.
"Natural draft opening" means any permanent opening, including
				doors and windows, in a total enclosure that remains open during operation of
				the lead emissions unit in the enclosure or enclosures and is not connected to
				a duct in which a fan is installed.
"New lead emission unit" means a lead emission unit constructed
				on or after January 1, 2015, at a nonferrous metal production facility.
"Nonferrous metal" means a metal that is not an iron or steel
				alloy; these metals may include alloys of aluminum, copper, lead, and
				zinc.
"Nonferrous metal production facility" means any source that is
				alloying, refining, or casting nonferrous metal or manufacturing nonferrous
				metal products, and where the source includes lead in their alloys or products
				by design.
"Production area" means an indoor space at a nonferrous metal
				production facility where lead emission units are operated.
"Quenching" means the process of cooling hot metal other than
				lead shot by direct contact of the metal with cooling water or other
				liquids.
"Refined lead" means a material composed of lead alloys of a
				specified composition from an onsite or offsite lead refining operation.
"Refining" means the process of removing impurities or oxides
				from a metal or metal alloy.
"Reverberatory furnace" means a refractory-lined furnace that
				uses one or more flames to heat the walls and roof of the furnace and
				lead-bearing scrap to such a temperature that lead compounds are chemically
				reduced to elemental lead metal.
"Rotary furnace" or "rotary reverberatory furnace" means a
				furnace consisting of a refractory-lined chamber that rotates about a
				horizontal axis and that uses one or more flames to heat the walls of the
				furnace and lead-bearing scrap to such a temperature that lead compounds are
				chemically reduced to elemental lead metal.
"Section Manager" means the Manager of the Agency's Bureau of
				Air, Compliance Section.
"Slag tap" means the pouring hole through which slag is removed
				from a kettle or furnace.
"Tap" means the pouring hole through which molten metal flows
				from a kettle or furnace.
"Tapping" means opening the tap.
"Total enclosure" means a complete enclosure with walls and a
				roof designed to minimize exposure to the elements and to maximize containment
				of emissions from one or more lead emission units and that meets the following
				performance standards: the average facial velocity of air flowing into the
				enclosure through all natural draft openings during operation of lead emission
				units in each total enclosure in any one hour period must be at least 200 fpm
				(3,600 m/hr) or average negative pressure value of 0.007 inches of water (0.013
				mm Hg) must be maintained inside the enclosure over any one hour period.
