As used in 19.0 of this regulation, all terms not defined herein shall have the meaning given them in the November 15, 1990 Clean Air Act Amendments, or in 2.0 of this regulation. "Metal furniture" means any furniture piece made of metal or any metal part that will be assembled with other metal, wood, fabric, plastic, or glass parts to form a furniture piece including, but not limited to, tables, chairs, waste baskets, beds, desks, lockers, benches, shelving, file cabinets, fixtures, lamps, lighting units, and room dividers.
"Metal furniture coating unit" means a coating unit in which a protective, decorative, or functional coating is applied onto the surface of metal furniture.
19.3 Standards 19.3.1 Except as provided in 19.4.1 of this regulation, no owner or operator of a metal furniture coating unit subject to 19.0 of this regulation shall cause or allow the application of any coating to metal furniture unless: 19.3.1.1 The VOC content of the coating is less than or equal to the limits listed in Table 19-1 of this regulation, or Table 19-1 Metal Furniture 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.

19.3.1.2 For a metal furniture coating unit that applies multiple coatings, which are subject to the same numerical emission limitation in Table 19-1 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 19-1 of this regulation corresponding to the category of coating used, or19.3.1.3 Control equipment is installed and operated that achieves an emission reduction efficiency in accordance with 19.5 of this regulation. The requirements of 19.3.2 of this regulation shall not apply to any metal furniture coating unit that achieves an emission reduction efficiency of 95% or greater.19.3.2 Except as provided in 19.3.1.3 and 19.4 of this regulation, no owner or operator of a metal furniture coating unit subject to 19.0 of this regulation shall apply a coating to metal furniture 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: 19.3.2.1 Electrostatic spray19.3.2.3 Dip coating, including electrodeposition19.3.2.5 High-volume, low-pressure (HVLP) spray19.3.2.6 Hand application19.3.2.7 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.19.4 Specific Exemptions 19.4.1 The requirements of 19.3.1 and 19.3.2 of this regulation shall not apply for the following types of coatings: 19.4.1.1 Stencil coatings19.4.1.2 Safety-indicating coatings19.4.1.3 Solid film lubricants19.4.1.4 Electric-insulating and thermal-conducting coatings19.4.1.5 Aerosol coating product19.4.2 The requirements of 19.3.2 of this regulation shall not apply to touch-up and repair coatings.19.5 Control Devices 19.5.1 An owner or operator of a metal furniture coating unit subject to 19.3.1.3 of this regulation shall determine the emission reduction efficiency needed to comply and demonstrate compliance as follows:19.5.1.1 Determine for each day the overall emission reduction efficiency needed to demonstrate compliance.
