Notice of Proposed Rule

(Amendment)

DAR File No.: 38686
Filed: 07/07/2014 10:45:07 AM

RULE ANALYSIS

Purpose of the rule or reason for the change:

The EPA has indicated that it cannot approve Rule R307-354 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.

]([3]2) The requirements of R307-354 shall not apply to any canned aerosol coating products.

 

R307-354-3. Definitions.

The following additional definitions apply to R307-354:

"Adhesion promoter" means a coating which is labeled and formulated to be applied to uncoated plastic surfaces to facilitate bonding of subsequent coatings, and on which, a subsequent coating is applied.

"Automotive" means passenger cars, vans, motorcycles, trucks, buses, golf carts and all other mobile equipment.

"Automotive refinishing" means the process of coating automobiles, after-market automobiles, motorcycles, light and medium-duty trucks and vans that are performed in auto body shops, auto repair shops, production paint shops, new car dealer repair and paint shops, fleet operation repair and paint shops, and any other facility which coats vehicles under the Standard Industrial Classification Code 7532 (Top, Body and Upholstery Repair Shops and Paint Shops). This includes dealer repair of vehicles damaged in transit. It does not include refinishing operations for other types of mobile equipment, such as farm machinery and construction equipment or their parts, including partial body collision repairs, that is subsequent to the original coating applied at an automobile original equipment manufacturing plant.

"Clear coating" means any coating that contains no pigments and is labeled and formulated for application over a color coating or clear coating.

"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.

"Color coating" means any pigmented coating, excluding adhesion promoters, primers, and multi-color coatings, that requires a subsequent clear coating and which is applied over a primer, adhesion promoter, or color coating. Color coatings include metallic and iridescent color coatings.

"Enclosed paint gun cleaner" means a cleaner consisting of a closed container with a door or top that can be opened and closed and fitted with cleaning connections. The spray gun is attached to a connection, and solvent is pumped through the gun and onto the exterior of the gun. Cleaning solvent falls back into the cleaner's solvent reservoir for recirculation.

"Metallic/Iridescent color coating" means a coating which contains iridescent particles, composed of either metal as metallic particles or silicon as mica particles, in excess of 0.042 pounds per gallon as applied, where such particles are visible in the dried film.

"Multi-color 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.

"Non-enclosed paint gun cleaner" means cleaner consisting of a basin similar to a sink in which the operator washes the outside of the gun under a solvent stream. The gun cup is filled with recirculated solvent, the gun tip is placed into a canister attached to the basin, and suction draws the solvent from the cup through the gun. The solvent gravitates to the bottom of the basin and drains through a small hole to a reservoir that supplies solvent to the recirculation pump.

"Pretreatment coating" means a coating which contains no more that 16% solids, by weight, and at least 0.5% acid, by weight, is used to provide surface etching, and is applied directly to bare metal surfaces to provide corrosion resistance and promote adhesion for subsequent coatings.

"Primer" means any coating which is labeled and formulated for application to a substrate to provide a bond between the substrate and subsequent coats; corrosion resistance; a smooth substrate surface; or resistance to penetration of subsequent coats, and on which a subsequent coating is applied. Primers may be pigmented.

"Single-stage coating" means any pigmented coating, excluding primers and multi-color coatings, labeled and formulated for application without a subsequent clear coat. Single-stage coatings include single-stage metallic/iridescent coatings.

"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.

"Temporary protective coating" means any coating which is labeled and formulated for the purpose of temporarily protecting areas form overspray or mechanical damage.

"Topcoat" means any coating or series of coatings applied over a primer or an existing finish for the purpose of protection or beautification.

"Truck bed liner coating" means any coating, excluding clear, color, multi-color, and single-stage coatings, labeled and formulated for application to a truck bed to protect it from surface abrasion.

"Underbody coating" means any coating labeled and formulated for application to wheel wells, the inside of door panels or fenders, the underside of a trunk or hood, or the underside of the motor vehicle.

"Uniform finish coating" means any coating labeled and formulated for application to the area around a spot repair for the purpose of blending a repaired area's color or clear coat to match the appearance of an adjacent area's existing coating. Prior to May 1, 2013, this coating category may be referred to as uniform finish blenders.

"Uniform finish blender" means a coating designed to blend a repaired topcoat into an existing topcoat.
