Sec. 2.
(a) The
				emission limitations specified in this article shall be achieved through one
				(1) or any combination of the following:
(1)
				Carbon adsorption.
(2) Thermal or
				catalytic incineration. The owner or operator of a source using a natural gas
				afterburner incineration method may petition the commissioner for permission to
				not operate the natural gas afterburner during the months of November,
				December, January, February, and March. The commissioner may allow such
				exemption if the owner or operator adequately demonstrates that the operation
				of the natural gas afterburner is not required for control of toxic substances
				or odor.
(3) Higher solids (low
				solvent) coatings, including powder, ultraviolet, and electron beam
				coatings.
(4) Waterborne
				coatings.
(5) Equivalent emission
				limitations based on an actual measured transfer efficiency greater than the
				specified baseline transfer efficiency as follows:
(A) This subdivision is applicable only to
				the following:
(i) 326 IAC 8-2-2(b)(2),
				automobiles and light duty truck assembly operations.
(ii) 326 IAC 8-2-6, metal furniture coating
				operations.
(iii) 326 IAC 8-2-7,
				large appliance coating operations.
(iv) 326 IAC 8-2-9, miscellaneous metal
				coating operations.
(B)
				For metal furniture coating operations, large appliance coating operations, or
				miscellaneous metal coating operations, this subdivision and the equivalent
				emission limits it contains may not be used to determine compliance unless a
				test method for determining actual measured transfer efficiency has been
				specified by U.S. EPA or submitted to U.S. EPA and approved as a SIP
				revision.
(C) The equivalent
				emission limitations in units of kilograms of volatile organic compounds (VOC)
				per liter solids deposited (pounds of VOC per gallon solids deposited),
				baseline transfer efficiencies, and baseline volume percent solids content of
				the coating are specified below:

				Compliance with an equivalent emission limit shall be determined as follows:
(i) For automobile and light duty topcoating
				operations and combined primer-surfacer and topcoat operations, use procedures
				found in "Protocol for Determining the Daily Volatile Organic Compound Emission
				Rate of Automobile and Light-Duty Truck Primer-Surfacer and Topcoat
				Operations"; EPA-453/R-08-002; September 2008*.
(ii) For metal furniture coating operations,
				large appliance coating operations, or miscellaneous metal coating operations
				use the following equation:

Where: E = Actual emissions in pounds of VOC per gallon of
				  coating solids deposited.
L = Actual VOC content in pounds of VOC per gallon of
				  coating, as applied, excluding water and nonphotochemically reactive
				  hydrocarbons.
D = Actual density of the VOC in the coating in pounds per
				  gallon of VOC.
T = Actual measured transfer efficiency.
(6) The use of
				nonphotochemically reactive hydrocarbons as defined in 326 IAC
				1-2-48.
(7) A daily volume-weighted
				average of all coatings applied in a coating line or printing line subject to
				the requirements in 326 IAC 8-2 or 326 IAC 8-5-5. Records of daily usage of
				gallons solids coating and VOC content of each coating, ink, and solvent shall
				be maintained and made available upon request. Also, records of daily emissions
				in pounds VOC shall be maintained and made available upon request. If daily
				records sufficient to determine an accurate daily weighted average are not
				available, each coating, ink, and solvent shall meet the requirements of the
				applicable section.
(8) The use of
				an emission control device specifically allowed under provisions of any rule in
				this article to meet the emission limitations specified in the rule.
(9) This subdivision is applicable only to
				dip coating or flow coating operations at miscellaneous metal coating
				operations subject to 326 IAC 8-2-9 as follows:
(A) For dip coating or flow coating
				operations only. The equivalent emission limit in kilograms VOC/liter
				(lb/gallon) of coating solids is as follows:
Miscellaneous metal coating category
Limit in kilograms VOC/liter (lb/gallon) of coating less
						  water
Equivalent emission limit in kilograms VOC/liter
						  (lb/gallon) of coating solids

						  ninety (90)

				Compliance with the equivalent emission limit shall be determined by doing the
				following:
(i) Calculate the VOC content of a
				dip coating or flow coating, expressed in units of weight of VOC per volume of
				coating solids, on a thirty (30) day rolling average basis using the following
				equation: VOCA = (3(Woi
												×
				Dci
												× Qi) + 3
				(WoJ
												× DdJ
												×
				QJ))/(3(Vni
												×
				Qi))
Where: VOCA = The as-applied, VOC
				  content in pound VOC per gallon (lb VOC/gal) of coating solids for a dip
				  coating or flow coating, calculated on a thirty (30) day rolling average
				  basis.
Woi = Percent VOC by weight of each as
				  supplied coating (i) added to the dip coating or flow 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 or flow coating process, in pounds per
				  gallon.
Qi = Quantity of each as supplied
				  coating (i) added to the dip coating or flow coating process, in
				  gallons.
Vni = Percent solids by volume of each
				  as supplied coating (i) added to the dip coating or flow coating process,
				  expressed as a decimal fraction.
WoJ = Percent VOC by weight of each
				  thinner (J) added to the dip coating or flow coating process, expressed as a
				  decimal fraction.
DdJ = Density of each thinner (J)
				  added to the dip coating or flow coating process, in pounds per gallon.
QJ = Quantity of each thinner (J)
				  added to the dip coating or flow coating process, in gallons.
(ii) Maintain the following records on a
				daily basis for each VOC-containing coating, solvent, or other material added
				to the tank:
(AA) The following parameters for
				each coating, thinner, or other material as supplied:
(aa) The coating, thinner, or other material
				identification number.
(bb) The
				volume used.
(cc) The mix
				ratio.
(dd) The density or specific
				gravity.
(ee) The weight percent of
				total volatiles, water, solids, and exempt solvents.
(ff) The volume percent of solids.
(BB) The VOC content of each
				coating and thinner as supplied.
(CC) The VOC content of each as-applied
				coating.

				year period.

				accessible for an additional two (2) years.
