or (h) of this title, to require compliance with the applicable contingency
measure control requirements of §115.453(h) or (i) of this title.
(b) General definitions. Unless specifically defined
in the Texas Clean Air Act (Texas Health and Safety Code, Chapter
382) or in §§3.2, 101.1, or 115.10 of this title (relating
to Definitions), the terms in this division have the meanings commonly
used in the field of air pollution control. In addition, the following
meanings apply in this division unless the context clearly indicates
otherwise.
(1) Aerosol coating (spray paint)--A hand-held, pressurized,
non-refillable container that expels an adhesive or a coating in a
finely divided spray when a valve on the container is depressed.
(2) Air-dried coating--A coating that is cured at a
temperature below 194 degrees Fahrenheit (90 degrees Celsius). These
coatings may also be referred to as low-bake coatings.
(3) Baked Coating--A coating that is cured at a temperature
at or above 194 degrees Fahrenheit (90 degrees Celsius). These coatings
may also be referred to as high-bake coatings.
(4) Coating application system--Devices or equipment
designed for the purpose of applying a coating material to a surface.
The devices may include, but are not be limited to, brushes, sprayers,
flow coaters, dip tanks, rollers, knife coaters, and extrusion coaters.
(5) Coating line--An operation consisting of a series
of one or more coating application systems and associated flash-off
area(s), drying area(s), and oven(s) wherein a surface coating is
applied, dried, or cured. The coating line ends at the point the coating
is dried or cured, or prior to any subsequent application of a different
coating.
(6) Coating solids (or solids)--The part of a coating
that remains on the substrate after the coating is dried or cured.
(7) Daily weighted average--The total weight of volatile
organic compounds (VOC) emissions from all coatings subject to the
same VOC limit in §115.453 of this title (relating to Control
Requirements), divided by the total volume or weight of those coatings
(minus water and exempt solvent), where applicable, or divided by
the total volume or weight of solids, delivered to the application
system on each coating line each day. Coatings subject to different
VOC content limits in §115.453 of this title may not be combined
for purposes of calculating the daily weighted average.
(8) Multi-component coating--A coating that requires
the addition of a separate reactive resin, commonly known as a catalyst
or hardener, before application to form an acceptable dry film. These
coatings may also be referred to as two-component coatings.
(9) Normally closed container--A container that is
closed unless an operator is actively engaged in activities such as
adding or removing material.
(10) One-component coating--A coating that is ready
for application as it comes out of its container to form an acceptable
dry film. A thinner, necessary to reduce the viscosity, is not considered
a component.
(11) Pounds of volatile organic compounds (VOC) per
gallon of coating (minus water and exempt solvent)--The basis for
content limits for surface coating processes that can be calculated
by the following equation:
Attached Graphic
(12) Pounds of volatile organic compounds (VOC) per
gallon of solids--The basis for emission limits for surface coating
processes that can be calculated by the following equation:
Attached Graphic
(13) Spray gun--A device that atomizes a coating or
other material and projects the particulates or other material onto
a substrate.
(14) Surface coating processes--Operations that use
a coating application system.
(c) Specific surface coating definitions. The following
meanings apply in this division unless the context clearly indicates
otherwise.
(1) Automobile and light-duty truck manufacturing--The
following definitions apply to this surface coating category.
(A) Adhesive--Any chemical substance that is applied
for the purpose of bonding two surfaces together other than by mechanical
means.
(B) Automobile and light-duty truck adhesive--An adhesive,
including glass-bonding adhesive, used in an automobile or light-duty
truck assembly surface coating process and applied for the purpose
of bonding two vehicle surfaces together without regard to the substrates
involved.
(C) Automobile and light-duty truck bedliner--A multi-component
coating used in an automobile or light-duty truck assembly surface
coating process and applied to a cargo bed after the application of
topcoat and outside of the topcoat operation to provide additional
durability and chip resistance.
(D) Automobile and light-duty truck cavity wax--A coating,
used in an automobile or light-duty truck assembly surface coating
process, applied into the cavities of the vehicle primarily for the
purpose of enhancing corrosion protection.
(E) Automobile and light-duty truck deadener--A coating
used in an automobile or light-duty truck assembly surface coating
process and applied to selected vehicle surfaces primarily for the
purpose of reducing the sound of road noise in the passenger compartment.
(F) Automobile and light-duty truck gasket/gasket sealing
material--A fluid used in an automobile or light-duty truck assembly
surface coating process and applied to coat a gasket or replace and
perform the same function as a gasket. Automobile and light-duty truck
gasket/gasket sealing material includes room temperature vulcanization
seal material.
(G) Automobile and light-duty truck glass-bonding primer--A
primer, used in an automobile or light-duty truck assembly surface
coating process, applied to windshield or other glass, or to body
openings, to prepare the glass or body opening for the application
of glass-bonding adhesives or the installation of adhesive-bonded
glass. Automobile and light-duty truck glass-bonding primer includes
glass-bonding/cleaning primers that perform both functions (cleaning
and priming of the windshield or other glass, or body openings) prior
to the application of an adhesive or the installation of adhesive-bonded
glass.
(H) Automobile and light-duty truck lubricating wax/compound--A
protective lubricating material used in an automobile or light-duty
truck assembly surface coating process and applied to vehicle hubs
and hinges.
