Section 326IAC8-2-7. Large appliance coating operations

   (a) This section is applicable to the surface coating of doors, cases, lids, panels, and interior support parts of the following residential and commercial products:

(1) Washers.

(2) Dryers.

(3) Ranges.

(4) Refrigerators.

(5) Freezers.

(6) Water heaters.

(7) Dishwashers.

(8) Trash compactors.

(9) Air conditioners.

(10) Other similar products.

  (b) No owner or operator of a large appliance coating line subject to this section may cause, allow, or permit the discharge into the atmosphere of any VOC in excess of thirty-four hundredths (0.34) kilogram per liter of coating (two and eight-tenths (2.8) pounds per gallon) excluding water, delivered to the coating applicator from prime, single, or topcoat coating operations.

  (c) On and after April 1, 2011, the owner or operator of a large appliance coating line in which the total actual VOC emissions from all large appliance coating operations, including related cleaning activities, are equal to or exceed fifteen (15) pounds per day, before add-on controls, located in Lake County or Porter County, shall comply with the following:

(1) VOC limitations for large appliance coating according to either of the following:

(A) Emission limits in terms of mass of VOC per volume of coating:

Coating Type	Maximum VOC Content
	Baked	Air Dried
	Kilograms/liter (pounds/gallon) of coating, excluding water, as applied	Kilograms/liter (pounds/gallon) of coating, excluding water, as applied
General, one component	0.275 (2.3)	0.275 (2.3)
General, multicomponent	0.275 (2.3)	0.340 (2.8)
Extreme high gloss	0.360 (3.0)	0.340 (2.8)
Extreme performance	0.360 (3.0)	0.420 (3.5)
Heat resistant	0.360 (3.0)	0.420 (3.5)
Metallic	0.420 (3.5)	0.420 (3.5)
Pretreatment coatings	0.420 (3.5)	0.420 (3.5)
Solar absorbent	0.360 (3.0)	0.420 (3.5)

(B) Emission limits in terms of mass of VOC per volume of coating solids, as applied:

Coating Type	Maximum VOC Content
	Baked	Air Dried
	Kilograms/liter (pounds/gallon) of coating solids, as applied	Kilograms/liter (pounds/gallon) of coating solids, as applied
General, one component	0.40 (3.3)	0.40 (3.3)
General, multicomponent	0.40 (3.3)	0.55 (4.5)
Extreme high gloss	0.61 (5.1)	0.55 (4.5)
Extreme performance	0.61 (5.1)	0.80 (6.7)
Heat resistant	0.61 (5.1)	0.80 (6.7)
Metallic	0.80 (6.7)	0.80 (6.7)
Pretreatment coatings	0.80 (6.7)	0.80 (6.7)
Solar absorbent	0.61 (5.1)	0.80 (6.7)

(2) As an alternative to subdivision (1), an owner or operator may achieve compliance with this subsection by using a capture and control device that achieves a minimum overall VOC control efficiency of ninety percent (90%).

(3) An owner or operator may also achieve compliance by using a combination of subdivisions (1) and (2). The required overall add-on control efficiency, when combining add-on control with low VOC coatings, must be determined using 326 IAC 8-1-2(c).

(4) One (1) or a combination of the following equipment shall be used for coating application:

(A) Electrostatic equipment.

(B) High volume low-pressure (HVLP) spray equipment.

(C) Flow coating.

(D) Roller coating.

(E) Dip coating, including electrodeposition.

(F) Other coating application method capable of achieving a transfer efficiency equivalent or better than achieved by HVLP spraying.

(5) Work practices shall be used to minimize VOC emissions from mixing operations, storage tanks, and other containers, and handling operations for cleaning material, coating materials, thinners, and cleaning-related waste materials. Work practices shall include, but not be limited to, the following:

(A) Store all VOC containing materials in closed containers.

(B) Ensure that mixing and storage containers used for VOC containing materials are kept closed at all times except when depositing or removing these materials.

(C) Minimize spills of VOC containing cleaning materials.

(D) Convey VOC containing cleaning materials from one (1) location to another in closed containers or pipes.

(E) Minimize the usage of solvents during the cleaning of storage, mixing, and conveying equipment.

  (d) The following exemptions apply in this section:

(1) The use of quick-drying lacquers for repair of scratches and nicks that occur during assembly are exempt from the requirements in subsection (b) (limited to one (1) gallon in an eight (8) hour period).

(2) The following coating types are exempt from the emission limitations in this section:

(A) Stencil coatings.

(B) Safety-indicating coatings.

(C) Solid film lubricants.

(D) Electric-insulating and thermal-conducting coatings.

(E) Touch-up and repair coatings.

(F) Hand-held aerosol can coatings.
