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 miscellaneous metal parts
				  and products surface coating facilities. This subchapter also establishes
				  requirements to demonstrate initial and continuous compliance with the emission
				  limits specified in s.
				  NR
				  465.43(1).
Note: This subchapter is based on the federal regulations
					 contained in 40 CFR part 63 Subpart MMMM, as last revised April 26,
					 2004.
(2) AM I SUBJECT TO
				  THIS SUBCHAPTER?
(a) Miscellaneous metal
				  parts and products include metal components of the following types of products
				  as well as the products themselves: motor vehicle parts and accessories,
				  bicycles and sporting goods, recreational vehicles, extruded aluminum
				  structural components, railroad cars, heavy duty trucks, medical equipment,
				  lawn and garden equipment, electronic equipment, magnet wire, steel drums,
				  industrial machinery, metal pipes, and numerous other industrial, household and
				  consumer products. Except as provided in par. (c), the source category to which
				  this subchapter applies is the surface coating of any miscellaneous metal parts
				  or products, as described in subd. 1., and it includes the sub-categories
				  listed in subds. 2. to 6.
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 high
				  performance, magnet wire, rubber-to-metal or extreme performance fluoropolymer
				  coating operations.
3. The high
				  performance coating sub-category includes surface coating operations that are
				  performed using coatings that meet the definition of high performance
				  architectural coating or high temperature coating in s.
				  NR
				  465.42(22).
4. The magnet wire coating sub-category
				  includes surface coating operations that are performed using coatings that meet
				  the definition of magnet wire coatings in s.
				  NR
				  465.42(26).
5. The rubber-to-metal coatings sub-category
				  includes surface coating operations that are performed using coatings that meet
				  the definition of rubber-to-metal coatings in s.
				  NR
				  465.42(39).
6. The extreme performance fluoropolymer
				  coatings sub-category includes surface coating operations that are performed
				  using coatings that meet the definition of extreme performance fluoropolymer
				  coatings in s.
				  NR
				  465.42(18).
