Current through June 24, 2024
(1) WHAT IS THE
				  PURPOSE OF THIS SUBCHAPTER? This subchapter establishes national emission
				  standards for hazardous air pollutants (NESHAP) for plastic parts and products
				  surface coating facilities. This subchapter also establishes requirements to
				  demonstrate initial and continuous compliance with the emission limits in s.
				  NR
				  465.33(1).
Note: This subchapter is based on the federal regulations
					 contained in 40 CFR part 63 Subpart PPPP, as last revised April 26,
					 2004.
(2) AM I SUBJECT TO
				  THIS SUBCHAPTER?
(a) Plastic parts and
				  products includes plastic components of the following types of products as well
				  as the products themselves: motor vehicle parts and accessories for
				  automobiles, trucks, recreational vehicles; sporting and recreational goods;
				  toys; business machines; laboratory and medical equipment; and household and
				  other consumer products. Except as provided in par. (c), the source category to
				  which this subchapter applies is the surface coating of any plastic parts or
				  products, as described in subd. 1., and includes the sub-categories listed in
				  subds. 2. to 5.
1. Surface coating is the
				  application of coating to a substrate. When application of coating to a
				  substrate occurs, then surface coating also includes associated activities,
				  such as surface preparation, cleaning, mixing and storage. However, these
				  activities do not comprise surface coating if they are not directly related to
				  the application of the coating. Coating application with hand-held,
				  non-refillable aerosol containers, touch-up markers, marking pens or the
				  application of paper film or plastic film which may be pre-coated with an
				  adhesive by the manufacturer are not coating operations for the purposes of
				  this subchapter.
2. The general use
				  coating sub-category includes all surface coating operations that are not
				  automotive lamp coating operations, thermoplastic olefin (TPO) coating
				  operations or assembled on-road vehicle coating operations.
3. The automotive lamp coating sub-category
				  includes the surface coating of plastic components of the body of an exterior
				  automotive lamp, including head lamps, tail lamps, turn signals and marker
				  lamps; typical coatings used are reflective agent coatings and clear topcoats.
				  This sub-category does not include the coating of interior automotive lamps,
				  such as dome lamps and instrument panel lamps.
4. The TPO coating sub-category includes the
				  surface coating of TPO substrates; typical coatings used are adhesion
				  promoters, color coatings, clear coatings and topcoats. The coating of TPO
				  substrates on fully assembled on-road vehicles is not included in the TPO
				  coating sub-category.
5. The
				  assembled on-road vehicle coating sub-category includes surface coating of
				  fully assembled motor vehicles and trailers intended for on-road use, including
				  automobiles, light-duty trucks, heavy duty trucks and buses that have been
				  repaired after a collision or otherwise repainted; fleet delivery trucks; and
				  motor homes and other recreational vehicles, including camping trailers and
				  fifth wheels. This sub-category also includes the incidental coating of parts
				  that are removed from the fully assembled on-road vehicle to facilitate
				  concurrent coating of all parts associated with the vehicle. The assembled
				  on-road vehicle coating sub-category does not include the surface coating of
				  plastic parts prior to their attachment to an on-road vehicle on an original
				  equipment manufacturer's assembly line. The assembled on-road vehicle coating
				  sub-category also does not include the use of adhesives, sealants and caulks
				  used in assembling on-road vehicles. Body fillers used to correct small surface
				  defects and rubbing compounds used to remove surface scratches are not
				  considered coatings subject to this subchapter.
