Notice of Proposed Rule

(Amendment)

RULE ANALYSIS

Purpose of the rule or reason for the change:

The EPA has indicated that it cannot approve Rule R307-346 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.

local governments:

There are no new requirements for local government; therefore, there are no anticipated costs or savings.

small businesses:

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.

[(1) ]R307-346 applies to sources located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber counties that have the potential to emit 2.7 tons per year or more of VOC, including related cleaning activities.

[(2) In Box Elder and Tooele counties, R307-346 applies to the following sources:

(a) Existing sources as of February 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 1, 2013 that have the potential to emit 2.7 tons per year or more of VOC, including related cleaning activities.

R307-346-3. Exemptions.

(1) The requirements of R307-346 do not apply to the following:

(a) Stencil coatings;

(b) Safety-indicating coatings;

(c) Solid-film lubricants;

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

(e) Touch-up and repair coatings; or

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

 

R307-346-4. Definitions.

The following additional definitions apply to R307-346:

"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.

"Application area" means the area where the coating is applied by spraying, dipping, or flow coating techniques.

"Baked coating" means a coating that is 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 applies to paints, sealants, caulks, inks, adhesives, and maskants.

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

"Maskants" means a material that protects a metal surface during the etching process.

"Metal furniture coating" means the surface coating of any furniture made of metal or any metal part that will be assembled with other metal, wood fabric, plastic, or glass parts to form a furniture piece.

 

R307-346-5. [Emission Standards]VOC Content Limits.

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 R307-346-7.
