NR 465.31NR 465.31 What this subchapter covers. NR 465.31(1)(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). NR 465.31 NoteNote: This subchapter is based on the federal regulations contained in 40 CFR part 63 Subpart PPPP, as last revised April 26, 2004. NR 465.31(2)(a)(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. NR 465.31(2)(a)1.1. 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. NR 465.31(2)(a)2.2. 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. NR 465.31(2)(a)3.3. 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. NR 465.31(2)(a)4.4. 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. NR 465.31(2)(a)5.5. 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.
