National Emission Standards for Hazardous Air Pollutants for 
Source Categories

CFR Correction

    In Title 40 of the Code of Federal Regulations, Part 63 (Sec. Sec.  
63.600 to 63.1199), revised as of July 1, 2011, on page 602, Sec.  
63.1196 is reinstated to read as follows:


Sec.  63.1196  What definitions should I be aware of?

    Terms used in this subpart are defined in the Act, in Sec.  63.2 of 
the general provisions in subpart A of this part, and in this section 
as follows:
    Bag leak detection system means a monitoring device for a fabric 
filter that identifies an increase in particulate matter emissions 
resulting from a broken filter bag or other malfunction and sounds an 
alarm.

[[Page 74709]]

    Bonded product means mineral wool to which a hazardous air 
pollutant-based binder (containing such hazardous air pollutants as 
phenol or formaldehyde) has been applied.
    CO means, for the purposes of this subpart, emissions of carbon 
monoxide that serve as a surrogate for emissions of carbonyl sulfide, a 
compound included on the list of hazardous air pollutants in section 
112 of the Act.
    Cupola means a large, water-cooled metal vessel to which is charged 
a mixture of fuel, rock and/or slag, and additives. As the fuel is 
burned, the charged mixture is heated to a molten state for later 
processing to form mineral wool.
    Curing oven means a chamber in which heat is used to thermoset a 
binder on the mineral wool fiber used to make bonded products.
    Fabric filter means an air pollution control device used to capture 
particulate matter by filtering gas streams through fabric bags. It 
also is known as a baghouse.
    Formaldehyde means, for the purposes of this subpart, emissions of 
formaldehyde that, in addition to being a HAP itself, serve as a 
surrogate for organic compounds included on the list of hazardous air 
pollutants in section 112 of the Act, including but not limited to 
phenol.
    Hazardous air pollutant means any air pollutant listed in or 
pursuant to section 112(b) of the Act.
    I means the owner or operator of a mineral wool production 
facility.
    Incinerator means an enclosed air pollution control device that 
uses controlled flame combustion to convert combustible materials to 
noncombustible gases.
    Melt means raw materials, excluding coke, that are charged into the 
cupola, heated to a molten state, and discharged to the fiber forming 
and collection process.
    Melt rate means the mass of molten material discharged from a 
single cupola over a specified time period.
    Mineral wool means a fibrous glassy substance made from natural 
rock (such as basalt), blast furnace slag or other slag, or a mixture 
of rock and slag. It may be used as a thermal or acoustical insulation 
material or in the making of other products to provide structural 
strength, sound absorbency, fire resistance, or other required 
properties.
    New source means any affected source the construction or 
reconstruction of which is commenced after May 8, 1997.
    PM means, for the purposes of this subpart, emissions of 
particulate matter that serve as a surrogate for metals (in particulate 
or volatile form) on the list of hazardous air pollutants in section 
112 of the Act, including but not limited to: antimony, arsenic, 
beryllium, cadmium, chromium, lead, manganese, nickel, and selenium.
    You means the owner or operator of a mineral wool production 
facility.
