R307-347-2. Applicability.

(1) R307-347 applies to large appliance surface coating operations located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber counties.

(2) Before September 1, 2018, R307-347 applies to large appliance surface coating operations that have the potential to emit 2.7 tons per year or more of VOC, including related cleaning activities.

(3) Effective September 1, 2018, R307-347 shall apply to large appliance surface coating operations that use a combined 20 gallons or more of coating products and associated solvents per year.

R307-347-3. Exemptions.

(1) The requirements of R307-347 do not apply to the following:

(a) Stencil coatings;

(b) Safety-indicating coatings;

(c) Solid-film lubricants;

(d) Electric-insulating and thermal-conducting coatings;

(e) Touch-up and repair coatings; or

(f) Coating applications utilizing hand-held aerosol cans.

R307-347-4. Definitions.

The following additional definitions apply to R307-347:

"Air dried coating" means coatings that are dried by the use of air or a forced warm air at temperatures up to 194 degrees Fahrenheit.

"As applied" means the VOC and solids content of the finishing material that is actually used for coating the substrate. It includes the contribution of materials used for in-house dilution of the finishing material.

"Baked coating" means a coating that is cured at a temperature at or above 198 degrees Fahrenheit.

"Extreme performance coatings" means coatings designed for harsh exposure or extreme environmental conditions.

"Large appliance" means doors, cases, lids, panels, and interior support parts of residential and commercial washers, dryers, ranges, refrigerators, freezers, water heaters, dishwashers, trash compactors, air conditioners, and other similar products.

R307-347-5. VOC Content Limits.

No owner or operator shall apply coatings with a VOC content greater than the amounts specified in Table 1, unless the owner or operator uses an add-on control device as specified in R307-347-7.

R307-347-6. Work Practices.

(1) The owner or operator shall:

(a) Store all VOC-containing coatings, thinners, and cleaning materials in closed containers;

(b) Minimize spills of VOC-containing coatings, thinners, and cleaning materials;

(c) Clean up spills immediately;

(d) Convey any coatings, thinners, and cleaning materials in closed containers or pipes;

(e) Close mixing vessels that contain VOC coatings and other materials except when specifically in use; and

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

(2) No person shall apply any coating unless the coating application method achieves a 65% or greater transfer efficiency. The following applications achieve a minimum of 65% transfer efficiency and shall be operated in accordance with the manufacturers specifications:

(a) Electrostatic application;

(b) Electrodeposition;

(c) Brush coat;

(d) Flow coat;

(e) Roll coat;

(f) Dip coat;

(g) High-volume, low-pressure (HVLP) spray; or

(h) Other application method capable of achieving 65% or greater transfer efficiency, as certified by the manufacturer.

(3) Solvent cleaning operations shall be performed using cleaning materials having a VOC composite vapor pressure no greater than 1 mm Hg at 20 degrees Celsius, unless an add-on control device is used as specified in R307-347-7.

R307-347-7. Add-On Controls Systems Operations.

(1) If an add-on control system is used, the owner or operator shall install and maintain the add-on emission control system in accordance with the manufacturer recommendations and maintain 90% or greater capture and control efficiency. The overall capture and control efficiency shall be determined using EPA approved methods, as follows.

(a) The capture efficiency of a VOC emission control system's VOC collection device shall be determined according to EPA's "Guidelines for Determining Capture Efficiency," January 9, 1995 and 40 CFR Part 51, Appendix M, Methods 204-204F, as applicable.

(b) The control efficiency of a VOC emission control system's VOC control device shall be determined using test methods in Appendices A-1, A-6, and A-7 to 40 CFR Part 60, for measuring flow rates, total gaseous organic concentrations, or emissions of exempt compounds, as applicable.

(c) An alternative test method may be substituted for the preceding test methods after review and approval by the EPA Administrator.

R307-347-8. Recordkeeping.

(1) The owner or operator shall maintain records of the following:

(a) Records that demonstrate compliance with R307-347. Records shall include, but are not limited to, inventory and product data sheets of all coatings and solvents subject to R307-347.

(b) If an add-on control device is used, records of key system parameters necessary to ensure compliance with R307-347-7.

(i) Key system parameters shall include, but are not limited to, temperature, pressure, flow rates, and an inspection schedule.

(ii) Key inspection parameters shall be in accordance with the manufacturer's recommendations, and as required to demonstrate operations are providing continuous emission reduction from the source during all periods that the operations cause emissions from the source.

(2) All records shall be maintained for a minimum of 2 years.

(3) Records shall be made available to the director upon request.
