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 AirActAmendments (CAAA), 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 of Voluntary Product Standard PS-59-73 as approved by the American National Standards Institute. 'Exterior siding' means wood panels with a flat surface made of solid wood, hardboard. or waferboard and are intended for use in commercial or residential construction, generally asa covering foran outside wall. 'Flatwood paneling coating line' means a coating line used to apply and dry orcure coatings applied to one ofthe following flat wood paneling product categories: printed interior panels made ofhardwood plywood and thin particle board (i.e., lessthan orequal to 0.64 centimeter (em) (0.25 inch [in.)) in thickness); natural finish hardwood plywood panels; and hardwood paneling with Class II finishes.

1"Hardboard" is a panel manufactured primarily from inter-felted ligno-<:ellulosic fibers that are consolidated under heatand pressure in a hot press. "Hardwood plywood" is plywood whose surface layer is a veneerofhardwood. "Natural finish hardwood plywood panels" means panels whose original grain pattern is enhanced by essentiallytransparentfinishes frequently supplemented byfillers and toners. "Printed interior panels" means panels whose grain or natural surface is obscured by fillers and basecoats upon which a simulated grain ordecorative pattern is printed. "Thin particleboard" is a manufactured board that is 0.64 cm (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 that meets the specifications for Class I hardboard given by the standard ANSIIAHA A135.4-1995 as approved by the American National Standards Institute. The standard specifies requirements and test methods for water absorption, thickness swelling, modulus of rupture, tensile strength, surface finish, dimensions, squareness, edge straightness, and moisture content for five classes of hardboard. Tileboard is also known as Class I hardboard ortempered hardboard. 23.3 Standards 23.3.1 Noowneroroperatorofa flatwood paneling coating line SUbject to 23.0 ofthis regUlation shall cause or allow, on any day,
