19.2.4. "Extreme environmental conditions" means any of the following: the weather all of the time, temperatures frequently above 95°C (203°F), detergents, abrasive and scouring agents, solvents, corrosive atmospheres, or similar environmental conditions.

19.2.5. "Extreme performance coatings" means coatings intended for exposure to extreme environmental conditions.

19.2.6. "Miscellaneous metal parts and products coating line" means a coating line in which a coating is applied to any miscellaneous metal parts and products.

19.2.7. "Miscellaneous parts and products" means any metal part or metal product, even if attached to or combined with a nonmetal part or product. Miscellaneous metal parts and products include, but are not limited to:

19.2.7.a. Large farm machinery (harvesting, fertilizing and planting machines, tractors, combines, etc.);

19.2.7.b. Small farm machinery (lawn and garden tractors, lawn mowers, rototillers, etc.);

19.2.7.c. Small appliances (fans, mixers, blenders, crock pots, dehumidifiers, vacuum cleaners, etc.);

19.2.7.d. Commercial machinery (office equipment, computers and auxiliary equipment, typewriters, calculators, vending machines, etc.);

19.2.7.e. Industrial machinery (pumps, compressors, conveyor components, fans, blowers, transformers, etc.);

19.2.7.f. Fabricated metal products (metal covered doors, frames, etc.);

19.2.7.g. Any other industrial category that coats metal parts or products under the Standard Industrial Classification Codes of Major Group 33 (primary metal industries), Major Group 34 (fabricated metal products), Major Group 35 (nonelectric machinery), Major Group 36 (electrical machinery), Major Group 37 (transportation equipment), Major Group 38 (miscellaneous instruments), and Major Group 39 (miscellaneous manufacturing industries); and

19.2.7.h. Application of underbody antichip materials (e.g., underbody plastisol) and coating application operations other than prime, primer surfacer, topcoat, and final repair operations at automobile and light-duty truck assembly plants.

19.2.8. "Pail" means any cylindrical metal shipping container of 1- to 12-gallon capacity and constructed of 29-gauge and heavier material.

19.2.9. "Refinishing" means the repainting of used equipment.

19.3. Standards.

19.3.1. No owner or operator of a miscellaneous metal parts and products coating line subject to this section 19. shall cause or allow the application of any coating with VOC content in excess of the emission limits in Table 45-21B.

Table 45-21B

Emission Limit	kg/L^a	lb/gal^a
Clear coating	0.52	4.3
Steel pail & drum interior coating	0.52	4.3
Air-dried coating	0.42	3.5
Extreme performance coating	0.42	3.5
All other coatings	0.36	3.0

a VOC content values are expressed in units of mass of VOC (kg, lb) per volume of coating (liter [L], gallon [gal]), minus water and exempt compounds, as applied.

19.3.2. If more than one emission limit in subdivision 19.3.1. applies to a specific coating, then the least stringent emission limit shall be applied.

19.3.3. As an alternative to compliance with the emission limits in subdivision 19.3.1., an owner or operator of a miscellaneous metal parts and products coating line may meet the requirements of subsection 19.4. or subsection 19.5.

19.4. No owner or operator of a miscellaneous metal parts and products coating line that applies multiple coatings, all of which are subject to the same numerical emission limitation within subdivision 19.3.1., during the same day (e.g., all coatings used on the line are subject to 0.42 kg/L [3.5 lb/gal]), shall apply coatings on that line during any day whose daily-weighted average VOC content calculated in accordance with the procedure specified in section 43. exceeds the coating VOC content limit corresponding to the category of coating used.

19.5. Control devices. -- An owner or operator of a miscellaneous metal parts and products coating line subject to this section 19. shall comply with this section 19. by:

19.5.1. Installing and operating a capture system on that line;

19.5.2. Installing and operating a control device on that line;

19.5.3. Determining for each day the overall emission reduction efficiency needed to demonstrate compliance. The overall emission reduction needed for a day is the lesser of the value calculated according to the procedure in subsection 43.2. for that day or 95 percent; and

19.5.4. Demonstrating each day that the overall emission reduction efficiency achieved for that day, as determined in subsection 44.3., is greater than or equal to the overall emission reduction efficiency required for that day.

19.6. Test methods. -- The test methods found in sections 41. through 44. shall be used to determine compliance with this section 19.

19.7. Recordkeeping and reporting.

19.7.1. An owner or operator of a miscellaneous metal parts and products coating line that is exempt from the emission limitations in subsection 19.3. shall comply with the certification, recordkeeping, and reporting requirements in subsection 4.2.

19.7.2. An owner or operator of a miscellaneous metal parts and products coating line subject to this section 19. and complying with subsection 19.3. by the use of complying coatings shall comply with the certification, recordkeeping, and reporting requirements in subsection 4.3.

19.7.3. An owner or operator of a miscellaneous metal parts and products coating line subject to this section 19. and complying with subsection 19.4. by daily-weighted averaging shall comply with the certification, recordkeeping, and reporting requirements in subsection 4.4.

19.7.4. An owner or operator of a miscellaneous metal parts and products coating line subject to this section 19. and complying with subsection 19.5. by the use of control devices shall comply with the testing, reporting, and recordkeeping requirements in subsection 4.5.
