Notice of Proposed Rule
DAR File No.: 38685
Filed: 07/07/2014 10:40:30 AM
Purpose of the rule or reason for the change:
The EPA has indicated that it cannot approve Rule R307-353 as a Reasonable Available Control Technology (RACT) rule as part of Utah's PM2.5 State Implementation Plan (SIP) until it is amended to clarify that the amount of control removal specified in each rule is based on the entire system and the inspection and recordkeeping requirements of the rule are expanded.
Summary of the rule or change:
The rule is amended to require an overall control efficiency of the add-on emission control system of 90%, clarify methodology for determining capture efficiency, and to include additional recordkeeping requirements for the add-on emission control system.
State statutory or constitutional authorization for this rule:
- Subsection 19-2-104(1)(a)
Anticipated cost or savings to:
the state budget:
There are no new requirements in this proposed rule for the State of Utah; therefore, there are no anticipated costs or savings.
There are no new requirements for local government; therefore, there are no anticipated costs or savings.
There are two options to reduce the emissions of VOCs. The first, and more cost-effective, option for small businesses is to use products that meet the VOC limits as specified in Table 1. The other option, which likely only very few larger sources would do, is to use an add-on emission control system that meets the 90% efficiency threshold.
persons other than small businesses, businesses, or local governmental entities:
There are no new requirements for persons other than small businesses, or local government entities; therefore, there are no anticipated costs or savings.
Compliance costs for affected persons:
There are two options to reduce the emissions of VOCs. The first, and more cost-effective option for small businesses, is to use products that meet the VOC limits as specified in Table 1. The other option, which likely only very few larger sources would do, is to use an add-on emission control system that meets the 90% efficiency threshold. It is difficult to determine the cost of installing and operating an add-on emission control system that meets the 90% requirements, as appropriate emission control systems for each source are extremely variable.
Comments by the department head on the fiscal impact the rule may have on businesses:
In most cases businesses will choose to use products that meet the VOC limits in Table 1 of the rule, as that option is usually the most cost-effective. Should a business choose to install and operate an add-on emission control system that meets the 90% overall capture and control efficiency, there would be additional costs to that business. However because appropriate emission control systems for each source are extremely variable, those costs are difficult to predict.

R307. Environmental Quality, Air Quality.
R307-353. Plastic Parts Coatings.
The purpose of this rule is to limit volatile organic compound (VOC) emissions from the application of coatings to any plastic product.
(1) ]R307-353 applies to plastic parts coating
operations located in
Cache, Davis, Salt Lake,
Utah and Weber counties that have the potential to
emit 2.7 tons per year or more of VOC, including related cleaning
(2) In Box Elder and Tooele counties, R307-353 applies to
the following sources: (a) Existing sources as of 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 May 1, 2013 that have the potential
to emit 2.7 tons per year or more of VOC, including related
(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.
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 a United States military 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.
