The owner or operator of the surface coating processes specified
in §115.420(a) of this title (relating to Applicability and Definitions)
shall not cause, suffer, allow, or permit volatile organic compound
(VOC) emissions to exceed the specified emission limits in paragraphs
(1) - (16) of this subsection. These limitations are based on the
daily weighted average of all coatings delivered to each coating line,
except for those in paragraph (9) of this subsection which are based
on paneling surface area, and those in paragraph (15) of this subsection
which, if using an averaging approach, must use one of the daily averaging
equations within that paragraph. The owner or operator of a surface
coating operation subject to paragraph (10) of the subsection may
choose to comply by using the monthly weighted average option as defined
in §115.420(c)(1)(YY) of this title.

must be achieved, on the basis of VOC solvent content per unit of
volume of coating (minus water and exempt solvent) delivered to the
application system:

(8) Miscellaneous metal parts and products (MMPP) coating.
(A) VOC emissions from the coating of MMPP must not
exceed the following limits for each surface coating type:
Attached Graphic
(B) If more than one emission limitation in subparagraph
(A) of this paragraph applies to a specific coating, then the least
stringent emission limitation applies.
(C) All VOC emissions from non-exempt solvent washings
must be included in determination of compliance with the emission
limitations in subparagraph (A) of this paragraph unless the solvent
is directed into containers that prevent evaporation into the atmosphere.
(9) Factory surface coating of flat wood paneling.
The following emission limits apply to each product category of factory-finished
paneling (regardless of the number of coats applied):
Attached Graphic
(10) Aerospace coatings. The VOC content of coatings,
including any VOC-containing materials added to the original coating
supplied by the manufacturer, that are applied to aerospace vehicles
or components must not exceed the following limits (in grams of VOC
per liter of coating, less water and exempt solvent). The following
applications are exempt from the VOC content limits of this paragraph:
manufacturing or re-work of space vehicles or antique aerospace vehicles
or components of each; touchup; United States Department of Defense
classified coatings; and separate coating formulations in volumes
less than 50 gallons per year to a maximum of 200 gallons per year
for all such formulations at an account.
(A) For the broad categories of primers, topcoats,
and chemical milling maskants (Type I/II) which are not specialty
coatings as listed in subparagraph (B) of this paragraph:
(i) primer, 350;
(ii) topcoats (including self-priming topcoats), 420;
and
(iii) chemical milling maskants:
(I) Type I, 622; and
(II) Type II, 160.
(B) For specialty coatings:

(11) Automobile and light-duty truck manufacturing
coating. The following VOC emission limits must be achieved, on the
basis of solvent content per unit volume of coating (minus water and
exempt solvents) delivered to the application system or for primer
surfacer and top coat application, compliance may be demonstrated
on the basis of VOC emissions per unit volume of solids deposited
as determined by §115.425(3) of this title (relating to Testing
Requirements).
Attached Graphic
(12) Vehicle refinishing coating (body shops). VOC
emissions from coatings or solvents must not exceed the following
limits, as delivered to the application system. Additional control
requirements for vehicle refinishing (body shops) are referenced in §115.422
of this title (relating to Control Requirements).

(13) Surface coating of mirror backing.
(A) VOC emissions from the coating of mirror backing
must not exceed the following limits for each surface coating application
method:
(i) 4.2 pounds per gallon (0.50 kg/liter) of coating
(minus water and exempt solvent) delivered to a curtain coating application
system; and
(ii) 3.6 pounds per gallon (0.43 kg/liter) of coating
(minus water and exempt solvent) delivered to a roll coating application
system.
(B) All VOC emissions from solvent washings must be
included in determination of compliance with the emission limitations
in subparagraph (A) of this paragraph, unless the solvent is directed
into containers that prevent evaporation into the atmosphere.
(14) Surface coating of wood parts and products. VOC
emissions from the coating of wood parts and products must not exceed
the following limits, as delivered to the application system, for
each surface coating type. All VOC emissions from solvent washings
must be included in determination of compliance with the emission
limitations in this paragraph, unless the solvent is directed into
