Current through Register Vol. 43, No. 39, September 26, 2024
(a) The provisions
of this regulation shall be applicable to each miscellaneous metal parts and
products and metal furniture coating application system at those facilities
which have a VOC potential contaminant emmission rate equal to or greater than
three tons per year on a facility-wide basis. The VOC potential contaminant
emission rate of a facility shall be determined by:
(1) the maximum hourly production rate of
each coating application system; and
(2) the assumption that the facility operates
24 hours per day, 365 days per year provided that the facility's operating
hours are not otherwise limited by federally enforceable permit conditions.
(b) This regulation
shall not be applicable to the following manufacturing categories which have
miscellaneous metal parts and products coating operations:
(1) automobiles and light duty trucks;
(2) metal cans;
(3) customized top coating of automobiles and
trucks, if less than 35 vehicles per day are processed; and
(4) automobile refinishing.
Each facility subject to this regulation shall remain subject
so long as this regulation remains in effect or until the facility's VOC
potential contaminant emission rate is demonstrated, to the satisfaction of the
department, to be always less than three tons per year.
(c) An owner or operator of any
facility subject to this regulation shall not conduct any surface coating
operation that emits VOC to the atmosphere in excess of that which would be
emitted by using the following coatings with the VOC content specified; (1)
through (5) applicable to miscellaneous metal parts and products, and (6)
applicable to metal furniture.
(1) 4.3 pounds
per gallon of coating, less water and exempt VOC, delivered to a coating
application system that applies clear coatings;
(2) 3.5 pounds per gallon of coating, less
water and exempt VOC, delivered to a coating application system that is
air-dried or forced warm air-dried at temperatures up to 194° F;
(3) 3.5 pounds per gallon of coating, less
water and exempt VOC, delivered to a coating application system that applies
extreme performance coatings except that coatings applied to the interior of
metal pails and metal drums may contain 4.3 pounds per gallon of coating, less
water and exempt VOC. As used in this regulation pails shall mean any nominal
cylindrical metal container of 1-12 gallon capacity, and drums shall mean any
cylindrical metal container of 13 to 110 gallons capacity;
(4) 0.4 pounds per gallon of coating, less
water and exempt VOC, delivered to a coating application system that applies
powder coatings;
(5) 3.0 pounds
per gallon of coating, less water and exempt VOC, delivered to a coating
application system for any other coating; and
(6) 3.0 pounds per gallon of coating, less
water and exempt VOC, delivered to a coating application system for prime,
top-coat or single coat operations.
(d) If more than one emission limitation in
subsection (c) applies to a specific coating, then the least stringent emission
limitation shall apply.
(e) Use of
additional VOC shall be considered as follows:
(1) for determining the potential contaminant
emission rate of the facility in accordance with subsection (a), include that
added for thinning coatings and that used for purging or washing coating
applicators which cannot be otherwise accounted for in a reclamation system;
and
(2) for compliance with
subsection (c), include that added for thinning coatings.
(f) The emission limits which will result
from the use of coatings in subsection (c) shall be achieved by:
(1) application of coatings which meet or
exceed the requirements of subsection (c) per coating application system on a
daily weighted average basis; or
(2) application of coatings with improved
transfer efficiency demonstrated, through testing, by methods approved by the
department, to achieve equivalent emissions based on the weight of VOC emitted
per gallon of solids applied as would be emitted with the coatings specified in
subsection (c) per coating application system on a daily weighted average
basis; or
(3) application, for the
capture and reduction of VOC emissions through either destruction or
collection, of a VOC vapor processing system demonstrated through testing as
capable of maintaining an overall VOC emission reduction of at least 90
percent. Use of a VOC vapor processing system shall require that continuous
monitors be installed, calibrated, operated, and maintained. The continuous
monitors shall continuously measure and record the following parameters:
(A) with an accuracy of the greater of
+0.75 percent of the temperature being measured
expressed in degrees Celsius, or 2.5 degrees Celsius, the exhaust gas
temperature of all VOC destruction devices and the gas temperature immediately
upstream and downstream of any catalyst bed;
(B) with an accuracy of
+2.00 percent of the amount being monitored, the
cumulative amount of VOC recovered during a calendar month for all VOC recovery
equipment;
(C) any other
parameters considered by the department necessary to achieve compliance with
this regulation; or
(4)
any combination of methods approved by the department which results in
emissions, when calculated as pounds of VOC per gallon of solids applied per
coating operation, that are no greater on a daily weighted average basis than
those achieved with the appropriate coatings specified in subsection (c).
(5) For the purpose of this
subsection the term "daily weighted average" is the total weight of VOC emitted
from a coating application system per day divided by the volume of coating used
or volume solids applied per day, depending on the units of the emission
limitation.
(g) Prior
to 180 days after a facility becomes subject to the provisions of this
regulation, the owner or operator of the facility shall demonstrate, at the
expense of the owner or operator, initial compliance with this regulation by
testing. An owner or operator shall notify the department, in writing, of the
intent to test not later than 30 days prior to the scheduled date of testing.
The owner or operator shall submit to the department any information about the
test requested by the department. If necessary to determine compliance with
this regulation, the owner or operator of any facility subject to this
regulation may be required to demonstrate compliance with this regulation by
testing at the expense of the owner or operator. Testing, for purposes of this
regulation, shall be approved by the department and consistent with:
(1) the test procedures found at 40 CFR Part
60, appendix A, as in effect July 1, 1989; and
(2) procedures as established by the
department in approving proposed test plans consistent with subsection (g)(1).
(h) Demonstration of
continual compliance per coating application system achieved by sections (f)(2)
through (f)(4) shall be based on the finding that the results obtained by the
formula in (2) are equal to or less than the results obtained by the forumla in
(1), both results on a daily weighted average basis.
(1) complying coating equivalent emissions
expressed as:
VOC, lbs / gal. of solids applied = (EL) / (TE)(VS)
EL = the coating characteristics established by this
regulation, expressed as pounds of VOC per gallon of coating, less water and
exempt VOC;
TE = baseline transfer efficiency as defined at K.A.R.
28-19-61, expressed as a decimal;
VS = volume fraction of solids in EL, expressed as a decimal,
where the density of coating solvents is assumed to be 7.36 pounds per gallon
(2) actual coating
equivalent emissions expressed as:
VOC, lbs / gal. of solids applied = (AC) (1-E) / (vs)(te)
AC = pounds of VOC per gallon of the coating as delivered to
the coating application system, less exempt VOC and water;
E = the demonstrated efficiency of installed vapor processing
system determined by the actual vapor collection system efficiency multiplied
by the actual VOC emissions control device efficiency, expressed as a decimal;
vs = volume fraction of solids of the coating as delivered to
the coating application system, expressed as a decimal. For water-borne
coatings the volume fraction of solids is determined without water;
te = the actual demonstrated transfer efficiency of the coating
application system, expressed as a decimal.
(A) The owner or operator shall determine AC
and vs by (1) using Reference Method 24 data supplied by the coating
manufacturer, adjusted by the VOC used for thinning purposes, or (2) from an
applied coating analysis conducted by the owner or operator in accordance with
Reference Method 24. If manufacturer's formulation data is used, verification
of the data may be required by Reference Method 24, or a department approved
equivalent method, and at the expense of the owner or operator.
(i) The owner or
operator of each emission unit within a facility subject to this regulation
shall keep and maintain records at the facility and make available for
inspection by a department representative to determine continuous compliance of
the facility with this regulation. The records shall include the following
information and shall be kept at the facility for two years following the date
of record:
(1) the type and amount of
coatings delivered daily to each coating application system. The daily
record-keeping requirements of this subsection may be waived if the owner or
operator:
(A) demonstrates that it uses only
coatings that have been determined to be in compliance with subsection (c) of
this regulation, and
(B) has
received written approval from the department for a waiver from this
requirement;
(2) the
manufacturer's coating formulation data, and other test data, including
density, weight percent volatiles (as determined using a one hour bake), weight
percent water, and weight percent exempt VOC, determined by Reference Method 24
for each coating;
(3) the
coating's solids content, as delivered to the coating application system, in
volume percent;
(4) the results of
any testing conducted at the facility pertaining to transfer efficiencies,
capture efficiencies or control equipment reduction efficiencies;
(5) the type, density and amount of solvents
used daily for coating thinning, purge and equipment cleaning;
(6) amount, components and density of waste
solvents reclaimed daily;
(7)
those records as required in subsections (f)(3)(A) through (f)(3)(C); and
(8) maintenance records of the
temperature monitoring equipment.
(j) The owner or operator of a facility shall
comply with all emission limits within 180 days after the facility becomes
subject to the provisions of this regulation.
(k) The provisions of this regulation shall
be applicable only to affected facilities located in areas which have been
identified as not meeting the national primary ambient air quality standard for
ozone in the manner prescribed by the provisions of Section 107(d) of the
federal clean air act, 42 U.S.C. 7407 as promulgated at 40 CFR Part 81 as in
effect July 1, 1989.
