Change in Proposed Rule (Second)

DAR File No.: 36738
Filed: 03/04/2013 11:51:25 AM

RULE ANALYSIS

Purpose of the rule or reason for the change:

During the public comment period, the Division of Air Quality (DAQ) staff determined that some of the language in the rule could be more clearly sated. DAQ also found a discrepancy in Section R307-343-8, where Tooele was not included in the compliance schedule.

Summary of the rule or change:

Most of the changes are to more clearly state language in the rule. For example, in Subsection R307-343-5(2), the phrase, "emission reductions" is changed to "transfer efficiency". Section R307-343-8 is amended by adding Tooele as a county in Utah where all applicable sources shall be in compliance with this rule by 01/01/2014. (DAR NOTE: This is the second change in proposed rule (CPR) for Rule R307-343. The original proposed amendment upon which the first CPR was based was published in the October 1, 2012, issue of the Utah State Bulletin, on page 56. The first CPR upon which this second CPR is based was published in the January 1, 2013, issue of the Utah State Bulletin, on page 49. Underlining in the rule below indicates text that has been added since the publication of the proposed rule mentioned above; strike out indicates text that has been deleted. You must view the first CPR, the second CPR, and the proposed amendment together to understand all of the changes that will be enforceable should the agency make this rule effective.)

R307-343. Emissions Standards for Wood Furniture Manufacturing Operations.

R307-343-1. Purpose.

The purpose of R307-343 is to limit volatile organic compound (VOC) emissions from wood furniture manufacturing.

 

R307-343-2. Applicability.

R307-343 applies to wood furniture manufacturing operations, including related cleaning activities, that have the potential to emit 2.7 tons or more per year of VOCs and that are located in Box Elder, Cache, Davis, Salt Lake, Utah, Tooele, and Weber counties.

 

R307-343-3. Definitions.

The following additional definitions apply to R307-343:

"Affected source" means a wood furniture manufacturing source that meets the criteria in R307-343-2.

"As applied" means the volatile organic compound 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.

"Coating" means a protective, decorative, or functional material applied in a thin layer to a surface. Such materials may include paints, topcoats, varnishes, sealers, stains, washcoats, basecoats, inks, and temporary protective coatings.

"Compliant coating" means a finishing material or strippable booth coating that meets the emission limits specified in R307-343-4(1).

"Control system" means the combination of capture and control devices used to reduce emissions to the atmosphere.

"Conventional Air Spray" means a spray coating method in which the coating is atomized by mixing it with compressed air at an air pressure greater than ten pounds per square inch (gauge) at the point of atomization. Airless, air assisted airless spray technologies, and electrostatic spray technology are not considered conventional air spray.

"Finishing material" means a coating used in the wood furniture industry, including basecoats, stains, washcoats, sealers, and topcoats.

"Finishing Operation" means those activities in which a finishing material is applied to a substrate and is subsequently air-dried, cured in an oven, or cured by radiation.

"Sealer" means a finishing material used to seal the pores of a wood substrate before additional coats of finishing material are applied. A washcoat used to optimize aesthetics is not a sealer.

"Solids" means the part of the coating that remains after the coating is dried or cured; solids content is determined using data from EPA Method 24.

"Stain" means any color coat having a solids content by weight of no more than 8.0% that is applied in single or multiple coats directly to the substrate, including nongrain raising stains, equalizer stains, sap stains, body stains, no-wipe stains, penetrating stains, and toners.

"Topcoat" means the last film-building finishing material applied in a finishing system. Non-permanent final finishes are not topcoats.

"Touch-up and Repair" means the application of finishing materials to cover minor finishing imperfections.

"Washcoat" means a transparent special purpose coating having a solids content by weight of 12.0% or less that is applied over initial stains to protect and control color and to stiffen the wood fibers in order to aid sanding.

"Washoff operations" means those operations in which organic solvent is used to remove coating from a substrate.

"Wood furniture" means any product made of wood, a wood product such as rattan or wicker, or an engineered wood product such as particleboard that is manufactured under any of the following standard industrial classification codes: 2434, 2511, 2512, 2517, 2519, 2521, 2531, 2541, 2599, or 5712.

"Wood furniture manufacturing operations" means the finishing, cleaning, and washoff operations associated with the production of wood furniture or wood furniture components.

(ii) Control system method is the use of a VOC control system achieving a 90% or greater emissions reduction.

(b) Using strippable spray booth coatings that contain no greater than 0.8 pounds VOC per pound solids as applied.

(c) Using closed containers for the storing of finishing, gluing, cleaning and washoff materials.

 

R307-343-5. Application Equipment Requirements.

(1) All coatings shall be applied using equipment having a minimum 65% transfer efficiency, except as allowed under R307-343-5(3) and operated according to the equipment manufacturer specifications. Equipment meeting the transfer efficiency requirement includes[, but is not limited to]:

(a) Brush, dip, or roll coating;

(b) Electrostatic application; and

(c) High volume, low pressure (HVLP) spray equipment.

(2) Other coating application methods that achieve [emission reductions]transfer efficiency equivalent to HVLP or electrostatic spray application methods may be used.

(3) Conventional air spray methods may be used under the following circumstances:

(a) To apply finishing materials that have no greater than 1.0 pound of VOC per pound of solids, as applied;

(b) For touch-up and repair under the following circumstances:

(i) The touchup and repair occurs after completion of the finishing operation; or

(ii) The touchup and repair occurs after the application of stain and before the application of any other type of finishing material, and the materials used for touchup and repair are applied from a container that has a volume of no more than 2.0 gallons;

(c) When the spray gun is aimed and triggered automatically, not manually;

(d) When the emissions from the finishing application station are directed to a control device;

(e) When the conventional air gun is used to apply finishing materials and the cumulative total usage of that finishing material is no more than 10% of the total gallons of finishing material used during the calendar year; or

(f) When the conventional air gun is used to apply stain on a part for which it is technically or economically infeasible to use any other spray application technology. The following criteria shall be used, either independently or in combination, to support the affected source's claim of technical or economic infeasibility:

(i) The production speed is too high or the part shape is too complex for one operator to coat the part and the application station is not large enough to accommodate an additional operator; or

(ii) The excessively large vertical spray area of the part makes it difficult to avoid sagging or runs in the stain.

 

R307-343-6. Control Systems Operations.

(1) Emission control systems shall be operated and maintained in accordance with the manufacturer recommendations in order to maintain 90% or greater continuous emission reduction[ of 90%].
