(a)
Applicability. This section applies as follows:
(1) This section applies to the owner and
operator of a large appliance or metal furniture surface coating process if the
total actual VOC emissions from all large appliance or metal furniture surface
coating operations, including related cleaning activities, at the facility are
equal to or greater than 15 pounds (6.8 kilograms) per day or 2.7 tons (2,455
kilograms) per 12-month rolling period, before consideration of
controls.
(2) The emission limits
and other requirements of this section supersede the emission limits and other
requirements of §
129.52 (relating to surface
coating processes) for large appliance and metal furniture surface coating
processes.
(b)
Existing RACT permit. The requirements of this section
supersede the requirements of a RACT permit issued to the owner or operator of
a source subject to subsection (a)(1) prior to January 1, 2011, under
§§
129.91-
129.95 (relating to stationary
sources of NOx and VOCs) to control, reduce or minimize VOCs from a large
appliance or metal furniture surface coating operation, except to the extent
the RACT permit contains more stringent requirements.
(c)
Emission limits.
Beginning January 1, 2011, a person subject to this section may not cause or
permit the emission into the outdoor atmosphere of VOCs from a large appliance
or metal furniture surface coating process, unless one of the following
limitations is met:
(1) The VOC content of
each as applied coating is equal to or less than the limit specified in Table I
or Table II (relating to emission limits of VOCs for large appliance surface
coatings; and emission limits of VOCs for metal furniture surface coatings).
(i) The VOC content of the as applied
coating, expressed in units of weight of VOC per volume of coating solids,
shall be calculated as follows:
VOC =
(Wo)(Dc)/Vn
Where:
VOC = VOC content in lb VOC/gal of coating solids
Wo = Weight percent of VOC
(Wv-Ww-Wex)
Wv = Weight percent of total
volatiles (100%-weight percent solids)
Ww = Weight percent of water
Wex = Weight percent of exempt
solvent(s)
Dc = Density of coating, lb/gal,
at 25° C
Vn = Volume percent of solids of
the as applied coating
(ii)
The VOC content of a dip coating, expressed in units of weight of VOC per
volume of coating solids, shall be calculated on a 30-day rolling average basis
using the following equation:

Where:
VOCA = VOC content in lb VOC/gal
of coating solids for a dip coating, calculated on a 30-day rolling average
basis
Woi = Percent VOC by weight of
each as supplied coating (i) added to the dip coating process, expressed as a
decimal fraction (that is 55% = 0.55)
Dci = Density of each as
supplied coating (i) added to the dip coating process, in pounds per gallon
Qi = Quantity of each as
supplied coating (i) added to the dip coating process, in gallons
Vni = Percent solids by volume
of each as supplied coating (i) added to the dip coating process, expressed as
a decimal fraction
WoJ = Percent VOC by weight of
each thinner (J) added to the dip coating process, expressed as a decimal
fraction
DdJ = Density of each thinner
(J) added to the dip coating process, in pounds per gallon
QJ = Quantity of each thinner
(J) added to the dip coating process, in gallons
(iii) Sampling and testing shall be done in
accordance with the procedures and test methods specified in Chapter 139
(relating to sampling and testing).
(2) The overall weight of VOCs emitted to the
atmosphere is reduced through the use of vapor recovery or incineration or
another method that is acceptable under §
129.51(a)
(relating to general). The overall efficiency of a control system, as
determined by the test methods and procedures specified in Chapter 139, may be
no less than 90% or may be no less than the equivalent efficiency as calculated
by the following equation, whichever is less stringent:
O = (1 - E/V) x 100
Where:
V = The VOC content of the as applied coating, in lb
VOC/gal of coating solids.
E = The Table I or Table II limit in lb VOC /gal of
coating solids.
O = The overall required control efficiency.
(d)
Compliance
monitoring procedures. The owner or operator of a facility subject to
this section shall maintain records sufficient to demonstrate compliance with
this section. At a minimum, the owner or operator shall maintain daily records
of:
(1) The following parameters for each
coating, thinner, component and cleaning solvent as supplied:
(i) Name and identification number.
(ii) Volume used.
(iii) Mix ratio.
(iv) Density or specific gravity.
(v) Weight percent of total volatiles, water,
solids and exempt solvents.
(vi)
Volume percent of solids for each Table I or Table II coating used in the
surface coating process.
(2) The VOC content of each coating, thinner,
component and cleaning solvent as supplied.
(3) The VOC content of each as applied
coating or cleaning solvent.
(e)
Recordkeeping and reporting
requirements. The records required under subsection (d) shall be:
(1) Maintained for 2 years, unless a longer
period is required under §
127.511(b)(2)
(relating to monitoring and related recordkeeping and reporting
requirements).
(2) Submitted to the
Department upon receipt of a written request.
(f)
Coating application
methods. A person subject to this section may not cause or permit the
emission into the outdoor atmosphere of VOCs from the application of large
appliance or metal furniture surface coatings, unless the coatings are applied
using one or more of the following coating application methods:
(1) Electrostatic coating.
(2) Roller coating.
(3) Flow coating.
(4) Dip coating, including
electrodeposition.
(5) High
volume-low pressure (HVLP) spray.

(7) Other coating application method, if
approved in writing by the Department prior to use.
(i) The coating application method must be
capable of achieving a transfer efficiency equivalent to or better than that

(3) Solid-film lubricants.
(4) Electric-insulating coatings.
(5) Thermal-conducting coatings.
(6) Touch-up and repair coatings.
(7) Coating applications using hand-held
