15A NCAC 02D .0967 MISCELLANEOUS METAL AND PLASTIC PARTS COATINGS



(a) For the purpose of this Rule, the following definitions apply:



(1) (2) (3) (4) (5) (6) (7)



(8) (9)



(10)



"Air dried coating" a means coating that is cured at a temperature below 90 degrees Celsius (194 degrees Fahrenheit). "Baked coating" means a coating that is cured at a temperature at or above 90 degrees Celsius (194 degrees Fahrenheit). "Clear coat" means a colorless coating which contains binders, but no pigment, and is formulated to form a transparent film. "Coating unit" means series one or more coating applicators and any associated drying area and oven wherein a coating is applied, dried, and cured. "Drum" means any cylindrical metal shipping container larger than 12 gallons capacity but no larger than 110 gallons capacity. "Electric dissipating coating" means a coating that rapidly dissipates a high voltage electric charge. "Electric-insulating varnish" means a non-convertible-type coating applied to electric motors, components of electric motors, or power transformers, to provide electrical, mechanical, and environmental protection or resistance. "Etching filler" means a coating that contains less than 23 percent solids by weight and at least 1/2percent acid by weight, and is used instead of applying a pretreatment coating followed by a primer. "Extreme high-gloss coating" means a coating which, when tested by the American Society for Testing Material Test Method D-523 adopted in 1980, shows a reflectance of 75 or more on a 60 degrees meter. "Extreme-performance coating" means a coating used on a metal or plastic surface where the coated surface is, in its intended use, subject to the following:



(A) (B) (C)



Chronic exposure to corrosive, caustic or acidic agents, chemicals, chemical fumes, chemical mixtures or solutions; Repeated exposure to temperatures in excess of 250 degrees Fahrenheit; or Repeated heavy abrasion, including mechanical wear and repeated scrubbing with industrial grade solvents, cleansers or scouring agents. Extreme performance coatings include coatings applied to locomotives, railroad cars, farm machinery, and heavy duty trucks.

(13) (14)



"High-performance architectural coating" means a coating used to protect architectural subsections and which meets the requirements of the Architectural Aluminum Manufacturer Association's publication number AAMA 2604-05 (Voluntary Specification, Performance Requirements and Test Procedures for High Performance Organic Coatings on Aluminum Extrusions and Panels) or 2605-05 (Voluntary Specification, Performance Requirements and Test Procedures for Superior Performing Organic Coatings on Aluminum Extrusions and Panels). "Miscellaneous metal product and plastic parts surface coatings" means the coatings that are applied to the surfaces of a varied range of metal and plastic parts and products. Such parts or products are constructed either entirely or partially from metal or plastic. These miscellaneous metal products and plastic parts include metal and plastic components of the following types of products as well as the products themselves: fabricated metal products, molded plastic parts, small and large farm machinery, commercial and industrial machinery and equipment, automotive or transportation equipment, interior or exterior automotive parts, construction equipment, motor vehicle accessories, bicycles and sporting goods, toys, recreational vehicles, pleasure craft (recreational boats), extruded aluminum structural components, railroad cars, heavier vehicles, lawn and garden equipment, business machines, laboratory and medical equipment, electronic equipment, steel drums, metal pipes, and other industrial and household products. "Multi-component coating" means a coating requiring the addition of a separate reactive resin, commonly known as a catalyst or hardener, before application to form a dry film. "One-component coating" means a coating that is ready for application as it comes out of its container to form a dry film. A thinner, necessary to reduce the viscosity, is not considered a component.



(b) This Rule applies to miscellaneous metal and plastic parts surface coating units whose volatile organic compounds emissions exceed the threshold established in Paragraph (b) of Rule .0902 of this Section for coating and related cleaning activities of the following types of products:



(1)



fabricated metal products, molded plastic parts, small and large farm machinery, commercial and industrial machinery and equipment;





(2) (3) (4) (5) automotive or transportation equipment, interior or exterior automotive parts, construction equipment, motor vehicle accessories, bicycles and sporting goods; toys, recreational vehicles, pleasure craft (recreational boats), extruded aluminum structural components, railroad cars, heavy vehicles, lawn and garden equipment; business machines, laboratory and medical equipment; and electronic equipment, steel drums metal pipes, and other industrial and household products.



(c) This Rule does not apply to:



(1) (2) (3)



coatings that are applied to test panels and coupons as part of research and development, quality control; performance testing activities at paint research or manufacturing facility; or sources covered by Rules .0921, .0922, .0923, .0935, .0936, .0961 .0962, .0963, .0964, .0965, .0966, and .0968 of this Section.



(d) With the exception stated in Paragraph (c) of this Rule, emissions of volatile organic compounds before control for surface coating of: (1) Metal parts and products shall not exceed limits as established in Table 1; Table 1. Metal Parts and Products Volatile Organic Compounds Content Limits
