(i) Atomized by forcing it through a small
				  nozzle at high pressure; and

				  Not mixed with air before exiting from the nozzle opening.
(b) Associated Parts and Components.
(i) "Associated parts and components" means a
				  structure, device, piece, module, section, assembly, subassembly, or element of
				  a motor vehicle or mobile equipment that is designed to be a part of the motor
				  vehicle or mobile equipment but which is not attached to the motor vehicle or
				  mobile equipment at the time of coating the structure, device, piece, module,
				  section, assembly, subassembly, or element.
(ii) "Associated parts and components" does
				  not include circuit boards.
(c) Automotive Coating.
(i) "Automotive coating" means a coating or
				  coating component used or recommended for use in motor vehicle or mobile
				  equipment refinishing, service, maintenance, repair, restoration, or
				  modification.
(ii) "Automotive
				  coating" includes any reference to automotive refinishing or automotive coating
				  recommended for use in motor vehicle or mobile equipment refinishing on the
				  container or in product literature.
(iii) "Automotive coating" does not include
				  metal plating activities.
(d) Automotive Coating Component.
(i) "Automotive coating component" means a
				  portion of a coating, including a reducer or thinner, toner, hardener, or
				  additive that is recommended by a person to distributors or end-users for use
				  in an automotive coating, or which is supplied for use in an automotive
				  coating.
(ii) "Automotive coating
				  component" does not include raw materials used to produce the
				  components.
(e)
				  "Automotive pretreatment coating" means a coating that:
(i) Contains a minimum of 0.5 percent acid by
				  weight and not more than 16 percent solids by weight necessary to provide
				  surface etching; and
(ii) Is
				  labeled and formulated for application directly to bare metal surfaces to
				  provide corrosion resistance and adhesion.
(f) "Automotive primer" means a coating
				  labeled and formulated for application to a substrate to provide one or more of
				  the following:
(i) A bond between the
				  substrate and subsequent coats;
(ii) Corrosion resistance;
(iii) A smooth substrate surface;
				  and
(iv) Resistance to penetration
				  of subsequent coats, and on which a subsequent coating is applied.
(g) Automotive Refinishing
				  Facility.
(i) "Automotive refinishing
				  facility" means a shop, business, location, or parcel of land where motor
				  vehicles or mobile equipment or their associated parts and components are
				  coated, including auto body collision repair shops.
(ii) "Automotive refinishing facility" does
				  not include the original equipment manufacturing plant where the new motor
				  vehicle or new mobile equipment is completely assembled.
(h) "CARB" means the California Air Resources
				  Board.
(i) Cleaning Solvent.
(i) "Cleaning solvent" means a fluid
				  containing VOC used to perform surface preparation, or cleaning of surface
				  coating equipment.
(ii) "Cleaning
				  solvent" does not include thinners, reducers or other solvents that may be used
				  to adjust the solvent content of coatings.
(j) Color Coating.
(i) "Color coating" means a pigmented
				  coating, excluding promoters, primers, and multicolor coatings that requires a
				  subsequent clear coating and which is applied over a primer, adhesion promoter,
				  or color coating.
(ii) "Color
				  coating" includes metallic/iridescent color coatings.
(k) "Electrostatic spray" means the
				  application of charged atomized paint droplets that are deposited by
				  electrostatic attraction.
(l)
				  "Exempt compound" means a compound identified as exempt under the definition of
				  volatile organic compound (VOC) under COMAR
				  26.11.01.01 a B(53).
(m) "Graphic arts operation" means the
				  application of logos, letters, numbers, or graphics to a painted surface by
				  brush, roller, or airbrush.
(n)
				  "Metallic/iridescent color coating" means a coating that:
(i) Exhibits more than one color in the dried
				  film after a single application;
(ii) Is packaged in a single
				  container;
(iii) Hides surface
				  defects on areas of heavy use; and
(iv) Is applied over a primer or adhesion
				  promoter.
(o) "Mobile
				  equipment" means any equipment which may be drawn or is capable of being drawn
				  or driven on a roadway or rails including but not limited to:
