23.1.4 Any facility that becomes or is currently SUbject to the provisions of23.0 ofthis regulation by exceeding the applicability threshold in 23.1.2.1 ofthis regulation will remain subject to these provisions even ifits emissions laterfall below the applicability threshold.
23.1.5 Any facility that is currently subject to a state or federal rule promUlgated pursuant to the Clean Air Act Amendments of 1977 by exceeding an applicability threshold is and will remain subject to these provisions, even ifits throughput or emissions have fallen or later fall belowthe applicability threshold. 23.2 Definitions. As used in 23.0 of this regulation, all terms not defined herein shall have the meaning given them in the November 15, 1990 Clean Air Act Amendments (CMA), or in 2.0 ofthis regulation. "Class I hardboard paneling finish" means finishes that meet the specifications for Class I of Voluntary Product Standard PS-59-73 as approved by the American National Standards Institute. "Class II hardboard paneling finish" means finishes that meet the specifications for Class II ofVoluntary Product Standard PS-59-73 as approved by the American National Standards Institute. "Flat wood paneling coating line" means a coating line used to apply and dry or cure coatings applied to one ofthe following flat wood paneling product categories: printed interior panels made of hardwood plywood and thin particle board (i.e., less than or equal to 0.64 centimeter (cm) (0.25 inch [in.]) in thickness); natural finish hardwood plywood panels; and hardwood panelingwith Class II finishes. "Hardboard" is a panel manufactured primarily from inter-felted Iigno-cellulosic fibers that are consolidated under heat and pressure in a hot press."Hardwood plywood" is plywood whose surface layerisa veneer of hardwood.
"Natural finish hardwood plywood panels" means panels whose original grain pattern is enhanced by essentiallytransparent finishes frequently supplemented by fillers andtoners.
"Printed interior panels" means panels whosegrain or natural surface isobscured by fillers and basecoats uponwhich a simulated grain ordecorative pattern is printed.
"Thin particleboard" is a manufactured board that is 

### 0.64 em 

### (0.25 in.) or less in thickness made of individual wood particles that have been coated with a binder and formed into flat sheets by pressure. "Tileboard" means paneling thathasa colored, waterproofsurface coating.
