(a) Except as provided in subsection (b),
this section applies to a person who applies mobile equipment repair and
refinishing or color matched coatings to mobile equipment or mobile equipment
components.
(b) This section does
not apply to a person who applies surface coating to mobile equipment or mobile
equipment components under one of the following circumstances:
(1) The surface coating process is subject to
the miscellaneous metal parts finishing requirements of §
129.52 (relating to surface
coating processes) or the requirements of §
129.52d (relating to control of
VOC emissions from miscellaneous metal parts surface coating processes,
miscellaneous plastic parts surface coating processes and pleasure craft
surface coatings).
(2) The surface
coating process is at an automobile assembly plant.
(3) The person applying the coatings does not
receive compensation for the application of the coatings.
(c) Beginning November 27, 2000, a person may
not apply to mobile equipment or mobile equipment components any automotive
pretreatment, automotive primer-surfacer, automotive primer-sealer, automotive
topcoat and automotive specialty coatings including any VOC-containing
materials added to the original coating supplied by the manufacturer, that
contain VOCs in excess of the limits specified in Table III.

(d) A person who provides mobile equipment
repair and refinishing coatings subject to this section shall provide
documentation concerning the VOC content of the coatings calculated in
accordance with the following:
(1) The mass
of VOC per combined volume of VOC and coating solids, less water and exempt
compounds, shall be calculated by the following equation:

where:
VOC = VOC content in grams per liter (g/l) of coating
less water and non-VOC solvents.
Wv = Mass of total volatiles, in
grams.
Ww = Mass of water, in grams.
Wec = Mass of exempt compounds,
in grams.
V = Volume of coating, in liters.
Vw = Volume of water, in
liters.
Vec = Volume of exempt
compounds, in liters.
To convert from grams per liter to pounds per gallon
(lb/gal), multiply the result (VOC content) by 8.345 x
10-3 (lb/gal/g/l).
(2) The VOC content of a multistage topcoat
shall be calculated by the following equation:
Click to view image
where:
VOCmulti = VOC content of multistage topcoat, g/l
VOCbc = VOC content of basecoat, g/l
VOCmci = VOC content of the midcoat(s), g/l
VOCcc = VOC content of the clear coat, g/l
M = number of midcoats
(e) Beginning November 27, 2000, a person at
a facility subject to this section shall use one or more of the following
application techniques to apply any finish material listed in Table III:
(1) Flow/curtain coating.
(2) Dip coating.
(3) Roller coating.
(4) Brush coating.
(5) Cotton-tipped swab application.
(6) Electrodeposition coating.
(7) High volume low pressure (HVLP)
spraying.
(8) Electrostatic
spray.
(9) Airless spray.
(10) Other coating application method that
the person demonstrates and the Department determines achieves emission
reductions equivalent to HVLP or electrostatic spray application
methods.
(f) The
following situations are exempt from the application equipment requirements in
subsection (e):
(1) The use of airbrush
application methods for stenciling, lettering and other identification
markings.
(2) The application of
coatings sold in nonrefillable aerosol containers.
(3) Automotive touch-up repair.
(g) Spray guns used to apply
mobile equipment repair and refinishing coatings shall be cleaned by one of the
following:
(1) An enclosed spray gun cleaning
system that is kept closed when not in use.
(2) Unatomized discharge of solvent into a
paint waste container that is kept closed when not in use.
(3) Disassembly of the spray gun and cleaning
in a vat that is kept closed when not in use.
(4) Atomized spray into a paint waste
container that is fitted with a device designed to capture atomized solvent
emissions.
(h) The owner
and operator of a facility subject to this section shall implement the
following housekeeping and pollution prevention and training measures:
(1) Fresh and used coatings, solvent and
cleaning solvents shall be stored in nonabsorbent, nonleaking containers. The
containers shall be kept closed at all times except when filling or
emptying.
(2) Cloth and paper, or
other absorbent applicators, moistened with coatings, solvents or cleaning
solvents, shall be stored in closed, nonabsorbent, nonleaking
containers.
(3) Handling and
transfer procedures shall minimize spills during the transfer of coatings,
solvents and cleaning solvents through the use of devices including pumps or
spouts on larger containers.
(4)
Ensure that a person who applies mobile equipment repair and refinishing
coatings has completed training in the proper use and handling of the mobile
equipment repair and refinishing coatings, solvents and waste products to
minimize the emission of air contaminants and to comply with this
section.
