Sec.  63.8665  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:
    Air pollution control device (APCD) means any equipment that
reduces the quantity of a pollutant that is emitted to the air.
    Bag leak detection system means an instrument that is capable of
monitoring PM loadings in the exhaust of a fabric filter in order to
detect bag failures. A bag leak detection system includes, but is not
limited to, an instrument that operates on triboelectric, light-
scattering, light-transmittance, or other effects to monitor relative
PM loadings.
    Clay ceramics manufacturing facility means a plant site that
manufactures pressed floor tile, pressed wall tile, other pressed tile,
or sanitaryware (e.g., sinks and toilets). Clay ceramics manufacturing
facilities typically process clay, shale, and various additives, form
the processed materials into tile or sanitaryware shapes, and dry and
fire the ceramic products. Glazes are applied to many tile and
sanitaryware products. A plant site that manufactures refractory
products, as defined in Sec.  63.9824, or brick and structural clay
products (BSCP), as defined in Sec.  63.8515, is not a clay ceramics
manufacturing facility.
