Current through Register Vol. 39, No. 2, July 15, 2024
For the purpose of this Section, the following definitions
					 shall apply:
(1) "Coating" means a
				  functional, protective, or decorative film applied in a thin layer to a
				  surface.
(2) "Coating applicator"
				  means an apparatus used to apply a surface coating.
(3) "Coating line" means one or more
				  apparatus or operations in a single line at which point a surface coating is
				  applied, dried, or cured and that include a coating applicator and flashoff
				  area and may include an oven or associated control devices.
(4) "Continuous vapor control system" means a
				  vapor control system that treats vapors displaced from tanks during filling on
				  a demand basis without intermediate accumulation.
(5) "Delivered to the applicator" means the
				  condition of coating after dilution by the user just before application to the
				  substrate.
(6) "Flashoff area"
				  means the space between the application area and the oven.
(7) "High solids coating" means a coating
				  that contains a higher percentage of solids and a lower percentage of volatile
				  organic compounds and water than conventional organic solvent borne
				  coatings.
(8) "Hydrocarbon" means
				  any organic compound of carbon and hydrogen only.
(9) "Incinerator" means a combustion
				  apparatus designed for high temperature operation in which solid, semisolid,
				  liquid, or gaseous combustible wastes are ignited and burned efficiently and
				  from which the solid and gaseous residues contain little or no combustible
				  material.
(10) "Intermittent vapor
				  control system" means a vapor control system that employs an intermediate vapor
				  holder to accumulate vapors displaced from tanks during filling. The control
				  device shall treat the accumulated vapors only during automatically controlled
				  cycles.
(11) "Loading rack" means
				  an aggregation or combination of loading equipment arranged so that all loading
				  outlets in the equipment can be connected to a cargo tank parked in a specified
				  loading space.
(12) "Low solvent
				  coating" means a coating that contains a substantially lower amount of volatile
				  organic compounds than conventional organic solvent borne coatings; it
				  typically falls into one of three major groups of high solids, waterborne, or
				  powder coatings.
(13) "Organic
				  material" means a chemical compound of carbon excluding carbon monoxide, carbon
				  dioxide, carbonic acid, metallic carbides or carbonates, and ammonium
				  carbonate.
(14) "Oven" means a
				  chamber used to bake, cure, polymerize, or dry a surface coating using
				  heat.
(15) "Potential emissions"
				  means the quantity of a pollutant that would be emitted at the maximum capacity
				  of a stationary source to emit the pollutant under its physical and operational
				  design. Any physical or operational limitation on the capacity of the source to
				  emit a pollutant, including air pollution control equipment and restrictions on
				  hours of operation or on the type or amount of material combusted, stored, or
				  processed, shall be treated as part of its design if the limitation or the
				  effect it would have on emissions is described or contained as a condition in
				  the federally enforceable permit. Secondary emissions do not count in
				  determining potential emissions of a stationary source. Fugitive emissions
				  count, to the extent quantifiable, in determining the potential emissions only
				  in these cases:
(a) petroleum
				  refineries;
(b) chemical process
				  plants; and
(c) petroleum storage
				  and transfer units with a total storage capacity exceeding 300,000
				  barrels.
