204 CLOSURE - Any component that is sued to close or seal a container

205 COIL - Any flat metal sheet or strip that is rolled or wound in concentric rings.

207 CONTAINER - Any three-piece can, two-piece can, drum, pail or tube.

208 DRUM - Any cylindrical metal shipping container larger than 12 gallons capacity but not larger than 110 gallons capacity.

209 ENCLOSED GUN WASHER - A washing system that has an enclosed solvent container, and uses non-atomized solvent flow to flush the spray equipment and collects and returns discharged solvent to the enclosed container.

210 END SEALING COMPOUND - A compound which is coated onto can ends and which functions as a gasket when the end is assembled onto the can.

211 EXEMPT COMPOUNDS - For the purposes of this rule, exempt compounds are the following:

212 EXTERIOR BASE COATING - A coating applied to the exterior of a container body to provide protection to the metal or to provide background for any lithographic or printing operation.

213 EXTERIOR BODY SPRAY - A coating sprayed on the exterior of a container body to provide a decorative or protective finish.

214 FOOD/BEVERAGE CAN - A metal container in which food or beverages intended for human consumption are packaged.

215 GRAMS OF VOC PER LITER OF COATING (AS APPLIED EXCLUDING WATER AND EXCLUDING EXEMPT COMPOUNDS) - The weight of VOC per combined volume of VOC and coating solids. This can be calculated by the following equation:
 

216 GRAMS OF VOC PER LITER OF MATERIAL - The weight of VOC per combined volume of material. This can be calculated by the following equation:
 

217 HIGH-VOLUME LOW-PRESSURE (HVLP) - A coating application system that is operated on a delivered air pressure between 0.1 and 10 psig air pressure.

218 INK - Any coating used in any operation that imparts color, design, alphabet, or numerals on an exterior surface of a metal container or closure.

219 INTERIOR BASE COATING - A coating applied to the interior of a container body to provide a protective lining between the product and the can.

220 INTERIOR BODY SPRAY - A coating sprayed on the interior of the container body to provide a protective film between the product and the can.

221 LUBRICANT APPLICATOR - An apparatus used to apply a surface lubricant to beverage container lid tabs.

222 NECKER LUBRICANT - Any fluid or solid applied to a can forming tool to reduce froiction while reducing the can diameter to form a neck.

223 OVERVARNISH - A coating applied directly over a design coating to reduce the coefficient of friction, to provide gloss and to protect the finish against abrasion and corrosion.

224 PAIL - Any metal container from 1 gallon to 12 gallon capacity and constructed of 29 gauge or heavier material.

225 RECONDITIONED DRUMS, PAILS, OR LIDS - Any drum, pail, or lid which is reused, recycled or remanufactured.

226 TAB PRESS LUBRICATION - The process that uses a lubricated mechanical press to create beverage container lid tabs from flat aluminum metal stock.

227 THREE-PIECE CAN SIDE-SEAM SPRAY - A coating sprayed on the interior and/or exterior of a welded, cemented or soldered seam to protect the exposed metal.

228 TWO-PIECE CAN EXTERIOR END COATING - A coating applied to the exterior end of a can to provide protection to the metal.

229 VOLATILE ORGANIC COMPOUND (VOC) - Any compound that contains at least one atom of carbon, except exempt compounds.

302 EMISSION CONTROL SYSTEM: Alternatively, a person may comply with the provisions of Section 301 by using an emission control system, provided that the overall efficiency of the system (capture efficiency multiplied by control efficiency) shall not be less than 85 percent by weight in reducing emissions of organic compounds. The total VOC emissions from operations under this section, considering capture and control efficiencies, shall be equivalent to or less than the VOC emissions level that would be achieved by complying with Section 301. The emission control system shall be approved in writing by the Air Pollution Control Officer in accordance with Rule 501, GENERAL PERMIT REQUIREMENTS.
