apply in the Beaumont-Port Arthur, Bexar County, Dallas-Fort Worth,
El Paso, and Houston-Galveston-Brazoria areas and in Gregg, Nueces,
and Victoria Counties.
(13) Mirror backing coating. The requirements in this
division apply in the Beaumont-Port Arthur, Bexar County, Dallas-Fort
Worth El Paso, and Houston-Galveston-Brazoria areas.

(b) General surface coating definitions. The following
terms, when used in this division have the following meanings, unless
the context clearly indicates otherwise. Additional definitions for
terms used in this division are found in §§3.2, 101.1, and
115.10 of this title (relating to Definitions).
(1) Aerosol coating (spray paint)--A hand-held, pressurized,
nonrefillable container that expels an adhesive or a coating in a
finely divided spray when a valve on the container is depressed.
(2) Coating--A material applied onto or impregnated
into a substrate for protective, decorative, or functional purposes.
Such materials include, but are not limited to, paints, varnishes,
sealants, adhesives, thinners, diluents, inks, maskants, and temporary
protective coatings.
(3) 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.
(4) Coating line--An operation consisting of a series
of one or more coating application systems and including associated
flashoff area(s), drying area(s), and oven(s) wherein a surface coating
is applied, dried, or cured.
(5) Coating solids (or solids)--The part of a coating
that remains after the coating is dried or cured.
(6) Daily weighted average--The total weight of volatile
organic compound (VOC) emissions from all coatings subject to the
same emission standard in §115.421 of this title (relating to
Emission Specifications), divided by the total volume of those coatings
(minus water and exempt solvent) delivered to the application system
each day. Coatings subject to different emission standards in §115.421
of this title must not be combined for purposes of calculating the
daily weighted average. In addition, determination of compliance is
based on each individual coating line.
(7) High-volume low-pressure spray guns--Equipment
used to apply coatings by means of a spray gun which operates between
0.1 and 10.0 pounds per square inch gauge air pressure at the air
cap.
(8) Normally closed container--A container that is
closed unless an operator is actively engaged in activities such as
adding or removing material.
(9) Pounds of VOC per gallon of coating (minus water
and exempt solvents)--Basis for emission limits for surface coating
processes. Can be calculated by the following equation:
Attached Graphic
(10) Pounds of VOC per gallon of solids--Basis for
emission limits for surface coating process. Can be calculated by
the following equation:
Attached Graphic
(11) Spray gun--A device that atomizes a coating or
other material and projects the particulates or other material onto
a substrate.
(12) Surface coating processes--Operations which utilize
a coating application system.
(13) Transfer efficiency--The amount of coating solids
deposited onto the surface of a part or product divided by the total
amount of coating solids delivered to the coating application system.
(c) Specific surface coating definitions. The following
terms, when used in this division, shall have the following meanings,
unless the context clearly indicates otherwise.
(1) Aerospace coating.
(A) Ablative coating--A coating that chars when exposed
to open flame or extreme temperatures, as would occur during the failure
of an engine casing or during aerodynamic heating. The ablative char
surface serves as an insulative barrier, protecting adjacent components
from the heat or open flame.
(B) Adhesion promoter--A very thin coating applied
to a substrate to promote wetting and form a chemical bond with the
subsequently applied material.
(C) Adhesive bonding primer--A primer applied in a
thin film to aerospace components for the purpose of corrosion inhibition
and increased adhesive bond strength by attachment. There are two
categories of adhesive bonding primers: primers with a design cure
at 250 degrees Fahrenheit or below and primers with a design cure
above 250 degrees Fahrenheit.
(D) Aerospace vehicle or component--Any fabricated
part, processed part, assembly of parts, or completed unit, with the
exception of electronic components, of any aircraft including but
not limited to airplanes, helicopters, missiles, rockets, and space
vehicles.
