| (a) The following control requirements apply to surface
coating processes subject to this division. Except as specified in
paragraph (3) of this subsection, these limitations are based on the
daily weighted average of all coatings, as defined in §101.1
of this title (relating to Definitions), as delivered to the application
system.
(1) The following limits must be met by applying low-volatile
organic compound (VOC) coatings to meet the specified VOC content
limits on a pound of VOC per gallon of coating basis (lb VOC/gal coating)
(minus water and exempt solvent), or by applying coatings in combination
with the operation of a vapor control system, as defined in §115.10
(relating to Definitions), to meet the specified VOC emission limits
on a pound of VOC per gallon of solids basis (lb VOC/gal solids).
If a coating meets more than one coating type definition, then the
coating with the least stringent VOC limit applies.
(A) Large appliances. If a coating does not meet a
specific coating type definition, then it can be assumed to be a general-use
coating and the VOC limit for general coating applies.

(B) Metal furniture. If a coating does not meet a specific
coating type definition, then it can be assumed to be a general-use
coating and the VOC limit for general coating applies.
Attached Graphic
(C) Miscellaneous metal parts and products. If a coating
does not meet a specific coating type definition, then it can be assumed
to be a general-use coating and the VOC limit for general coating
applies.
Attached Graphic
(D) Miscellaneous plastic parts and products. If a
coating does not meet a specific coating category definition, then
it can be assumed to be a general-use coating and the VOC limit for
general coating applies.
Attached Graphic
(E) Automotive/transportation and business machine
plastic parts. For red, yellow, and black automotive/transportation
coatings, except touch-up and repair coatings, the VOC limit is determined
by multiplying the appropriate limit in Table 1 of this subparagraph
by 1.15.
Attached Graphic
(F) Pleasure craft. If a coating does not meet a specific
coating category definition, then it can be assumed to be a general-use
coating and the VOC limits for other coatings applies.
Attached Graphic
(2) The coating VOC limits for motor vehicle materials
applied to the metal and plastic parts in paragraph (1)(C) - (F) of
this subsection, as delivered to the application system, must be met
using low-VOC coatings (minus water and exempt solvent).
Attached Graphic
(3) The coating VOC limits for automobile and light-duty
truck assembly surface coating processes must be met by applying low-VOC
coatings.

(A) The owner or operator shall determine compliance
with the VOC limits for electrodeposition primer operations on a monthly
weighted average in accordance with §115.455(a)(2)(D) of this
title (relating to Approved Test Methods and Testing Requirements).
(B) As an alternative to the VOC limit in Table 1 of
this paragraph for final repair coatings, if an owner or operator
does not compile records sufficient to enable determination of the
daily weighted average, compliance may be demonstrated each day by
meeting a standard of 4.8 lb VOC/gal coating (minus water and exempt
solvent) on an occurrence weighted average basis. Compliance with
the VOC limits on an occurrence weighted average basis must be determined
in accordance with the procedure specified in §115.455(a)(2)
of this title.
(C) The owner or operator shall determine compliance
with the VOC limits in Table 2 of this paragraph in accordance with §115.455(a)(1)
or (2)(C) of this title, as appropriate.
(4) The coating VOC limits for paper, film, and foil
surface coating processes must be met by applying low-VOC coatings
to meet the specified VOC content limits on a pound of VOC per pound
of coating basis, as delivered to the application system, or by applying
coatings in combination with the operation of a vapor control system
to meet the specified VOC emission limits on a pound of VOC per pound
of solids basis, as delivered to the application system.
Attached Graphic
(5) An owner or operator applying coatings in combination
with the operation of a vapor control system to meet the VOC emission
limits in paragraph (1) or (4) of this subsection shall use the following
equation to determine the minimum overall control efficiency necessary
to demonstrate equivalency. Control device and capture efficiency
testing must be performed in accordance with the testing requirements
in §115.455 (a)(3) and (4) of this title.
Attached Graphic
(b) Except for the surface coating process in subsection
(a)(2) of this section, the owner or operator of a surface coating
process may operate a vapor control system capable of achieving a
90% overall control efficiency as an alternative to subsection (a)
of this section. Control device and capture efficiency testing must
be performed in accordance with the testing requirements in §115.455(a)(3)
and (4) of this title. If the owner or operator complies with the
overall control efficiency option under this subsection, then the
owner or operator is exempt from the application system requirements
of subsection (c) of this section.
(c) The owner or operator of any surface coating process
subject to this division shall not apply coatings unless one of the
following coating application systems is used:
(1) electrostatic application;
(2) high-volume, low-pressure (HVLP) spray;
(3) flow coat;
(4) roller coat;
(5) dip coat;
(6) brush coat or hand-held paint rollers; or
(7) for metal and plastic parts surface coating processes
specified in §115.450(a)(3) and (4) of this title (relating to
Applicability and Definitions), airless spray or air-assisted airless
spray; or
(8) other coating application system capable of achieving
a transfer efficiency equivalent to or better than that achieved by
HVLP spray. For the purpose of this requirement, the transfer efficiency
of HVLP spray is assumed to be 65%. The owner or operator shall demonstrate
that either the application system being used is equivalent to the
transfer efficiency of an HVLP spray or that the application system
being used has a transfer efficiency of at least 65%.
(d) The following work practices apply to the owner
or operator of each surface coating process subject to this division.
(1) For all coating-related activities including, but
not limited to, solvent storage, mixing operations, and handling operations
for coatings and coating-related waste materials, the owner or operator
shall:

to comply with the work practice plan required by this paragraph.
(e) A surface coating process that becomes subject
to subsection (a) of this section by exceeding the exemption limits
in §115.451 of this title (relating to Exemptions) is subject
to the provisions in subsection (a) of this section even if throughput
or emissions later fall below exemption limits unless emissions are
maintained at or below the controlled emissions level achieved while
complying with subsection (a) of this section and one of the following
conditions is met.
(1) The project that caused throughput or emission
rate to fall below the exemption limits in §115.451 of this title
must be authorized by a permit, permit amendment, standard permit,
or permit by rule required by Chapters 106 or 116 of this title (relating
