Change in Proposed Rule

DAR File No.: 41823
Filed: 10/05/2017 12:40:46 PM

RULE ANALYSIS

Purpose of the rule or reason for the change:

The rule changes are being proposed in response to comments received during the public comment period. The amendments to this rule strengthen the area source coating rules. These amendments will help further reduce Volatile Organic Compound (VOC) emissions and will be part of the upcoming Serious PM2.5 State Implementation Plan (SIP).

Summary of the rule or change:

Several changes were made throughout Rule R307-353 as a result of public comments. These changes include: adding a compliance schedule for affected sources; adding a definition for medical device; adding exemptions for aerospace vehicles and components; coating products on medical devices up to 800 pounds of VOC per year; and research and development, quality control, or performance testing activities. (EDITOR'S NOTE: The original proposed amendment upon which this change in proposed rule (CPR) was based was published in the July 1, 2017, issue of the Utah State Bulletin, on page 142. 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 CPR and the proposed amendment together to understand all of the changes that will be enforceable should the agency make this rule effective.)

Statutory or constitutional authorization for this rule:

  • Subsection 19-2-104(1)(a)

Anticipated cost or savings to:

the state budget:

There is no cost or savings to the state budget as a result of these changes because the changes do not change the way the rule impacts the state.

local governments:

There is no cost or savings to local governments as a result of these changes because the changes do not affect the way the rule impacts local governments.

small businesses:

The new exemptions may lead to savings for small businesses; however, it is difficult to determine the amount of the savings to be realized. The other changes would not result in additional costs.

persons other than small businesses, businesses, or local governmental entities:

Persons other than small businesses, businesses, or local government entities will not be impacted by these changes because the rule does not apply to them.

Compliance costs for affected persons:

There will be no added compliance costs because of these changes. The changes, the added compliance schedule for affected sources; added definition for medical device; added exemptions for aerospace vehicles and components, coating products on medical devices up to 800 pounds of VOC per year; and research and development, quality control, or performance testing activities, do not result in additional compliance costs because the requirements of the rule otherwise remain unchanged.

Comments by the department head on the fiscal impact the rule may have on businesses:

The new exemptions may lead to savings for businesses; however, it is difficult to determine the amount of the savings to be realized. The other changes would not result in additional costs because the changes simply clarify the purpose of the 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.

"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.

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

"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.

"Medical device" means an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent or other similar article including any component or accessory, that is intended for use in the diagnosis of disease or other conditions or in the cure, mitigation, treatment, or prevention of disease, or is intended to affect the structure or any function of the body. For the purpose of this rule, a medical device shall also include associated manufacturing or assembly apparatus.

"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.
