Wisconsin Administrative Code › Department of Natural Resources › NR 400-499 - Environmental Protection - Air Pollution Control › Chapter NR 465 - National emission standards for hazardous air pollutants for general surface coating processes › Subchapter III - Surface Coating of Large Appliances › Section NR 465.21 - What this subchapter covers

Current through June 24, 2024
(1) WHAT IS THE
				  PURPOSE OF THIS SUBCHAPTER?. This subchapter establishes national emission
				  standards for hazardous air pollutants for large appliance surface coating
				  facilities. This subchapter also establishes requirements to demonstrate
				  initial and continuous compliance with the emission limitations.
Note: This subchapter is based on the federal regulations
					 contained in 40 CFR part 63 Subpart NNNN, created July 23, 2002.
(2) AM I SUBJECT TO THIS
				  SUBCHAPTER?.
(a) You are subject to this
				  subchapter if you own or operate a facility that applies coatings to large
				  appliance parts or products, and is a major source, is located at a major
				  source or is part of a major source of emissions of hazardous air pollutants
				  (HAP), except as provided in par. (d). A major source of HAP emissions is any
				  stationary source or group of stationary sources located within a contiguous
				  area and under common control that emits or has the potential to emit any
				  single HAP at a rate of 9.07 Mg (10 tons) or more per year or any combination
				  of HAP at a rate of 22.68 Mg (25 tons) or more per year. You are not subject to
				  this subchapter if your large appliance surface coating facility is located at,
				  or is part of, an area source of HAP emissions. An area source of HAP emissions
				  is any stationary source or group of stationary sources located within a
				  contiguous area and under common control that is not a major source.
(b) The large appliance surface coating
				  source category includes any facility engaged in the surface coating of a large
				  appliance part or product. Large appliance parts and products include cooking
				  equipment; refrigerators, freezers, and refrigerated cabinets and cases;
				  laundry equipment; dishwashers, trash compactors, and water heaters; and
				  heating, ventilation and air-conditioning (HVAC) units, air-conditioning units
				  except those in motor vehicles, air-conditioning and heating combination units,
				  comfort furnaces, and electric heat pumps. Specifically excluded are heat
				  transfer coils and large commercial and industrial chillers.
(c) The large appliance surface coating
				  activities and equipment to which this subchapter applies are all of the
				  following:
1. Surface preparation of large
				  appliance parts and products.
2.
				  Preparation of a coating for application, e.g., mixing in thinners and other
				  components.
3. Application of a
				  coating to large appliance parts and products using, for example, spray guns or
				  dip tanks.
4. Application of
				  porcelain enamel, powder coating and asphalt interior soundproofing
				  coating.
5. Flash-off, drying or
				  curing following the coating application operation.
6. Cleaning of equipment used in coating
				  operations, e.g., application equipment, hangers and racks.
7. Storage of coatings, thinners and cleaning
				  materials.
8. Conveying of
				  coatings, thinners and cleaning materials from storage areas to mixing areas or
				  coating application areas, either manually such as in buckets or by automated
				  means such as by transfer through pipes using pumps.
9. Handling and conveying of waste materials
				  generated by coating operations.
(d) This subchapter does not apply to any of
				  the following:
1. The surface coating of large
				  appliance parts such as metal or plastic handles, hinges or fasteners that have
				  a wider use beyond large appliances.
2. The surface coating of large appliances
				  conducted for the purpose of repairing or maintaining large appliances used by
				  a facility and not for commerce unless organic HAP emissions from the surface
				  coating itself are as high as the rates specified in par. (a).
3. The surface coating of heat transfer coils
				  or large commercial and industrial chillers.
4. Research or laboratory facilities;
				  janitorial, building, and facility maintenance operations; hobby shops operated
				  for noncommercial purposes or coating applications using hand-held
				  non-refillable aerosol containers.
5. Processes involving metal plating or
				  phosphating of a substrate.
(e) If you own or operate an affected source
				  that is subject to this subchapter and at the same affected source you also
				  perform surface coating subject to any other national emission standards for
				  hazardous air pollutants (NESHAP), you may choose for the affected source to
				  comply with only one NESHAP. In order to choose this alternative, the total
				  mass of organic HAP emissions from all surface coating operations in the
				  affected source shall be less than or equal to the total mass of organic HAP
				  emissions that would result if it complied separately with all applicable
				  NESHAP. You shall make this comparison for the initial compliance period and
				  report it in the notification of compliance status as required in s.
				  NR 465.25(1)
				  (b) 10. and in the notification of compliance
				  status required by the other NESHAP. If you choose this alternative, your
				  demonstration of compliance with the other NESHAP constitutes compliance with
				  this subchapter.
