DAR File No.: 36735
Filed: 03/04/2013 11:53:35 AM

RULE ANALYSIS

Purpose of the rule or reason for the change:

During the public comment period, the Division of Air Quality (DAQ) staff identified areas in the rule text that needed to be changed in order to more accurately state the rule applicability.

Summary of the rule or change:

Changes are made throughout the rule to ensure that it is clear that the rule applies to plastic parts coating operations. A definition for "plastic" is added. Table 1 is changed by replacing "VOC EMISSION RATES" with "VOC CONTENT LIMITATIONS". Other style, formatting, and grammar changes are made. (DAR NOTE: This is the second change in proposed rule (CPR) for Rule R307-353. The original proposed new rule upon which the first CPR was based was published in the October 1, 2012, issue of the Utah State Bulletin, on page 85. 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 75. Underlining in the rule below indicates text that has been added since the publication of the proposed new rule mentioned above; strike out indicates text that has been deleted. You must view the first CPR, the second CPR, and the proposed new rule together to understand all of the changes that will be enforceable should the agency make this rule effective.)

(2) In Box Elder and Tooele counties, R307-353 applies to the following sources:

(a) Existing sources as of [February]May 1, 2013 with the potential to emit 5 tons per year or more of VOC, including related cleaning activities; and

(b) New sources as of [February]May 1, 2013 that have the potential to emit 2.7 tons per year or more of VOC, including related cleaning activities.

 

R307-353-3. Exemptions.

(1) The provisions of this rule shall not apply to any of the following:

(a) Stencil coatings;

(b) Safety-indicating coatings;

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

(d) Magnetic data storage disk coatings;

(e) Plastic extruded onto metal parts to form a coating; and

(f) Textured finishes.

(2) If a coating line is subject to the requirements for existing automobile, light-duty truck, and other product and material coatings or for existing metallic surface coating lines, the coating line shall be exempt from this rule.

 

R307-353-4. Definitions.

The following additional definitions apply to R307-353:

"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.

"Baked coating" means coatings that are cured at a temperature at or above 194 degrees Fahrenheit.

"Coating" means a protective, functional, or decorative film applied in a thin layer to a surface. This term often applies to paints such as lacquers or enamels. It is also used to refer to films applied to paper, plastics, or foil.

"Electric-insulating and thermal-conducting" means a coating that displays an electrical insulation of at least 1000 volts DC per mil on a flat test plate and an average thermal conductivity of at least 0.27 BTU per hour-foot-degree-Fahrenheit.

"Magnetic data storage disk coating" means a coating used on a metal disk which stores data magnetically.

"Metallic coating" means a coating which contains more than 5 grams of metal particles per liter of coating as applied.

"Military specification coating" means a coating which has a formulation approved by [the]a United States [M]military [A]agency for use on military equipment.

"Mirror backing" means the coating applied over the silvered surface of a mirror.

"Mold-seal coating" means the initial coating applied to a new mold or a repaired mold to provide a smooth surface which, when coated with a mold release coating, prevents products from sticking to the mold.

"Multi-colored coating" means a coating which exhibits more than one color when applied, and which is packaged in a single container and applied in a single coat.

"Multi-component coating" means a coating requiring the addition of a separate reactive resin, commonly known as a catalyst, before application to form an acceptable dry film.

"One-component coating" means a coating that is ready for application as it comes out of its container to from an acceptable dry film. A thinner necessary to reduce the viscosity is not considered a component.

"Optical coating" means a coating applied to an optical lens.

"Plastic" means a substrate containing one or more resigns that may be solid, porous, flexible, or rigid, and includes fiber reinforced plastic composites.

"Primer" means a coating applied to a surface to provide a firm bond between the substrate and subsequent coats.

"Repair coating" means a coating used to recoat portions of a part or product which has sustained mechanical damage to the coating.

"Roller Coated" means a type of coating application equipment that utilizes a series of mechanical rollers to form a thin coating film on the surface of a roller, which is then applied to a substrate by moving the substrate underneath the roller.

"Safety-indicating coating" means a coating which changes physical characteristics, such as color, to indicate unsafe condition.

"Stencil coating" means an ink or a coating which is rolled or brushed onto a template or stamp in order to add identifying letters or numbers to metal parts and products.

"Textured finish" means a rough surface produced by spraying and splattering large drops of coating onto a previously applied coating. The coatings used to form the appearance of the textured finish are referred to as textured coatings.

"Touch-up coating" means a coating used to cover minor coating imperfections appearing after the main coating operation.

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

 

R307-353-5. Emission Standards.

(1) For automobile and truck plastic parts coating lines:

(a) Each owner or operator shall not apply coatings with a VOC content in excess of the amounts specified in Table 1 or shall use an add-on control device as specified in R307-353-8.

(b) For red and black coatings, the emission limitation shall be determined by multiplying the appropriate limit in Table 1 by 1.15.

(c) When EPA Method 24 is used to determine the VOC content of a high bake coating, the applicable emission limitation shall be determined by adding 0.5 to the appropriate limit in Table 1.

(d) When EPA Method 24 is used to determine the VOC content of an air-dried coating, the applicable emission limitation shall be determined by adding 0.1 to the appropriate limit in Table 1.
