(a)
Applicability. Except as specified in paragraphs (1)-(3), this
section applies to the owner and operator of a flat wood paneling surface
coating process if the total actual VOC emissions from all flat wood paneling
surface coating operations listed in Table I (relating to emission limits of
VOCs for flat wood paneling surface coatings), including related cleaning
activities, at the facility are equal to or greater than 15 pounds (6.8
kilograms) per day, before consideration of controls. This section does not
apply to the following:
(1) A field-applied
coating process. Field-applied coatings are regulated under Chapter 130,
Subchapter C (relating to architectural and industrial maintenance
coatings).
(2) A coating process
regulated under §§
129.101-
129.107 (relating to wood
furniture manufacturing operations).
(3) A coating process regulated under
§§
129.52(f) and
129.52, Table I, Category 11
(relating to surface coating processes; and wood furniture manufacturing
operations).
(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 flat wood
paneling 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 this section may not cause or permit the emission into the outdoor
atmosphere of VOCs from a flat wood paneling 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.
(i) The VOC content of each 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 limits in Table I may be met by calculating a weighted average
of the VOC content of all coatings used on a single flat wood paneling surface
coating process line each day. The daily weighted average shall be calculated
using the following equation:

Where:
VOCw = The daily weighted
average VOC content, as applied, of all coatings used on a single flat wood
paneling surface coating process line, in lb VOC/gal of coating solids.
n = The number of different coatings used each day on
the single flat wood paneling surface coating process line.
Vi = The volume solids for each
coating, as applied, used each day on the single flat wood paneling surface
coating process line, in gallons.
Ci = The VOC content of each
coating, as applied, used each day on the single flat wood paneling surface
coating process line, in lb VOC/gal coating solids.
Vt = The total volume of solids
for all coatings combined, as applied, used each day on the single flat wood
paneling surface coating process line, 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 oxidation or solvent recovery 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 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. The owner or operator shall maintain daily records of:
(1) The following parameters for each
coating, thinner, other component or cleaning solvent as supplied:
(i) Name and identification number of the
coating, thinner, other component or cleaning solvent.
(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 coating used in the flat wood paneling
coating process.
(vii) VOC
content.
(2) 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 a flat wood paneling surface
coating process unless the coatings are applied using one or more of the
following coating application methods:
(1)
Offset rotogravure coating.
(2)
Curtain coating.
(3) Direct roll
coating.
(4) Reverse roll
coating.
(5) Hand brush or hand
roller coating.
(6) High volume-low
pressure (HVLP) spray coating.
(7)

(i) The coating application method must be
capable of achieving a transfer efficiency equivalent to or better than that
achieved by a method listed in paragraphs (1)-(9).
(ii) The request for approval must be
submitted in writing.
(g)
Exempt coatings. The VOC
coating content standards in Table I do not apply to a coating used exclusively
for determining product quality and commercial acceptance and other small
quantity coatings, if the coating meets the following criteria:
(1) The quantity of coating used does not
exceed 50 gallons per year for a single coating and a total of 200 gallons per
year for all coatings combined for the facility.
(2) The owner or operator of the facility
requests, in writing, and the Department approves, in writing, the exemption
prior to use of the coating.
