20.2 Definitions. As used in 20.0 of this regulation, all terms not defined herein shall have the meaning given them in the November 15, 1990 Clean Air Act Amendments (CAAA), or in 2.0 of this regulation.
“Large appliance” means any residential or commercial washer, dryer, range, oven, microwave oven, refrigerator, freezer, water heater, dishwasher, trash compactor, air conditioner, or other similar products under North American Industry Classification System code 33522.
“Large appliance coating unit” means a coating unit in which any protective, decorative, or functional coating is applied onto the surface of component metal parts (including, but not limited to, doors, cases, lids, panels, and interior parts) of large appliances.
20.3 Standards
20.3.1 Except as provided in 20.4.1 of this regulation, no owner or operator of a large appliance coating unit subject to 20.0 of this regulation shall cause or allow the application of any coating to large appliances unless:
20.3.1.1 The VOC content of the coating is less than or equal to the limits listed in Table 20-1 of this regulation, or
Table 20-1 Large Appliance Coating VOC Content Limits
VOC content limits are expressed as mass (either kilogram [kg] or pound [lb]) per volume (either liter [l] or gallon [gal]) of coating less water and exempt compounds, as applied.

20.3.1.2 For a large appliance coating unit that applies multiple coatings, which are subject to the same numerical emission limitation in Table 20-1 of this regulation, the daily-weighted average VOC content, calculated in accordance with the procedure specified in Appendix C of this regulation, is less than or equal to the limit in Table 20-1 of this regulation corresponding to the category of coating used, or
20.3.1.3 Control equipment is installed and operated that achieves an emission reduction efficiency in accordance with 20.5 of this regulation. The requirements of 20.3.2 of this regulation shall not apply to any large appliance coating unit that achieves an emission reduction efficiency of 95% or greater.
20.3.2 Except as provided in 20.3.1.3 and 20.4 of this regulation, no owner or operator of a large appliance coating unit subject to 20.0 of this regulation shall apply a coating to large appliances unless the coating is applied with equipment properly operating and maintained according to the manufacturer's suggested guidelines and using one or more of the following coating application methods:
20.3.2.1 Electrostatic spray
20.3.2.2 Flow coating
20.3.2.3 Dip coating, including electrodeposition
20.3.2.4 Roll coating
20.3.2.5 High-volume, low-pressure (HVLP) spray
20.3.2.6 Hand application
20.3.2.7 An alternative method that is demonstrated to be capable of achieving a transfer efficiency equal to or better than HVLP spray and approved by the Department and by the EPA.
20.4 Specific Exemptions
20.4.1 The requirements of 20.3.1 and 20.3.2 of this regulation do not apply for the following types of coatings:
20.4.1.1 Stencil coatings
20.4.1.2 Safety-indicating coatings
20.4.1.3 Solid film lubricants
