(a)
Applicability. This section applies to the owner and operator
of a paper, film or foil surface coating process, as follows, if the surface
coating process meets one or a combination of the following:
(1) The emission limits in Table I and other
requirements of this section apply to the owner and operator of a paper, film
or foil surface coating process if an individual paper, film or foil surface
coating line has a potential to emit at least 25 tpy of VOC from coatings,
prior to controls. For these processes, the emission limits and other
requirements of this section supersede the emission limits and other
requirements of §
129.52 (relating to surface
coating processes).
(2) The
emission limit in Table II and other requirements of this section apply to the
owner and operator of a paper surface coating process which emits or has
emitted VOCs into the outdoor atmosphere in quantities greater than 3 pounds
(1.4 kilograms) per hour, 15 pounds (7 kilograms) per day or 2.7 tons (2,455
kilograms) per year during any calendar year since January 1, 1987. For these
processes, the emission limit and other requirements of this section supersede
the emission limit and other requirements of §
129.52.
(3) The work practice requirements for
cleaning materials found in subsection (h), and the related compliance
monitoring and recordkeeping and reporting requirements of subsections (d) and
(e), apply to the owner and operator of a paper, film or foil surface coating
process if the total actual VOC emissions from all paper, film or foil 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.
(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) prior to January 1, 2012, under §§
129.91-
129.95 (relating to stationary
sources of NOx and VOCs) to control, reduce or minimize VOCs from a paper, film
or foil surface coating process, except to the extent the RACT permit contains
more stringent requirements.
(c)
Emission limits. Beginning January 1, 2012, a person subject
to subsection (a)(1) or (2) may not cause or permit the emission into the
outdoor atmosphere of VOCs from a paper, film or foil 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, as
applicable.
(i) The VOC content of the as
applied coating, expressed in units of weight of VOC per weight of coating
solids, shall be calculated as follows:
VOCB =
(Wo)/(Wn)
Where:
VOCB = VOC content in lb VOC/lb
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
solvents
Wn = Weight percent of solids of
the as applied coating
(ii)
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
(iii)
The VOC content of a dip coating, expressed in units of weight of VOC per
weight of coating solids, shall be calculated on a 30-day rolling average basis
using the following equation:

Where:
VOCA = VOC content in lb VOC/lb
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
Wni = Percent solids by weight
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
(iv) 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 overall 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/lb of coating solids or lb voc/gal of coating solids.
E = The Table I limit in lb VOC/lb of coating solids or
Table II limit in lb voc/gal of coating solids.
O = The overall required control efficiency.
(d)
