RULE ANALYSIS

Purpose of the rule or reason for the change:

Amendments to this rule were last adopted by the Air Quality Board in November 2012. Since that time, several regulated facilities have notified the Division of Air Quality (DAQ) that they are having difficulties implementing the requirements of Section R307-335-7. Based on these comments, DAQ staff have determined that the rule should be amended.

Summary of the rule or change:

Subsection R307-335-7(1) is amended by adding exemptions for electrical and electronic components and for operations that are exclusively covered by Department of Defense military technical data and performed on site at installations owned or operated by the United States Armed Forces. Language is added to Subsection R307-335-7(2) to clarify the 15-pound/day rule applicability is from the cleaning process. The compliance schedule of the rule is changed to the effective date of this rulemaking.

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 for the state; therefore, there are no anticipated costs or savings to the state budget.

local governments:

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

small businesses:

There are no new requirements for small businesses; therefore, there are no anticipated costs or savings.

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

There are no new requirements for persons other than small businesses, businesses, or local government entities; therefore, there are no costs or savings.

Compliance costs for affected persons:

There are no added compliance costs added to this rule. In fact, this rulemaking will mitigate potential compliance costs for affected persons, as it adds two new exemptions to the rule.

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

This rulemaking will mitigate the compliance costs for some businesses as it adds two new exemptions to the rule.

R307-335. Degreasing and Solvent Cleaning Operations.

R307-335-3. Definitions.

The following additional definitions apply to R307-335:

"Batch open top vapor degreasing" means the batch process of cleaning and removing grease and soils from metal surfaces by condensing hot solvent vapor on the colder metal parts.

"Cold cleaning" means the batch process of cleaning and removing soils from metal surfaces by spraying, brushing, flushing or immersing while maintaining the solvent below its boiling point.

"Conveyorized degreasing" means the continuous process of cleaning and removing greases and soils from metal surfaces by using either cold or vaporized solvents.

"Department of Defense military technical data" means a specification that specifies design requirements, such as materials to be used, how a requirement is to be achieved, or how an item is to be fabricated or constructed.

"Freeboard ratio" means the freeboard height (distance between solvent line and top of container)divided by the width of the degreaser.

"Industrial solvent cleaning" means operations performed using a liquid that contains any VOC, or combination of VOCs, which is used to clean parts, tools, machinery, equipment and work areas. Cleaning operations include, but are not limited to, spraying, wiping, flushing, and purging.

"Open top vapor degreaser" means the batch process of cleaning and removing soils from metal surfaces by condensing low solvent vapor on the colder metal parts.

"Separation operation" means any process that separates a mixture of compounds and solvents into two or more components. Specific mechanisms include extraction, centrifugation, filtration, and crystallization.

"Solvent metal cleaning" means the process of cleaning soils from metal surfaces by cold cleaning, open top vapor degreasers, or conveyorized degreasing.

 

R307-335-7. Industrial Solvent Cleaning.

(1) Exemptions. The requirements of R307-335-7 do not apply to aerospace, wood furniture, shipbuilding and repair, flat wood paneling, large appliance, metal furniture, paper film and foil, plastic parts, miscellaneous metal parts coatings and light autobody and truck assembly coatings, flexible packaging, lithographic and letterpress printing materials, [and ]fiberglass boat manufacturing materials, electrical and electronic components, and operations that are exclusively covered by Department of Defense military technical data and performed on site at installations owned and/or operated by the United States Armed Forces.

(2) Operators of industrial solvent cleaning that emit 15 pounds of VOCs or more per day from industrial solvent cleaning operations, [before controls, ]shall reduce VOC emissions from the use, handling, storage, and disposal of cleaning solvents and shop towels by implementing the following work practices:

(a) Covering open containers; and

(b) Storing used applicators and shop towels in closed fire proof containers.

(3) Owners or operators of industrial solvent cleaning operations shall limit VOC emissions by either:

(a) Using cleaning solutions with vapor pressure less than or equal to eight millimeters of mercury (mm Hg) at 20 degrees C;

(b) Using solvents with a VOC content of 0.42 pounds per gallon or less; or

(c) Installing an emission control system designed to have an overall control efficiency of at least 85%.

 

R307-335-10. Compliance Schedule.

(1) All sources [within Salt Lake and Davis counties]defined in R307-335-2 shall be in compliance with R307-335[-3 through R307-335-6 and R307-335-8 upon the effective date.

(2) All other sources defined in R307-335-2 shall be in compliance with all sections of this rule by September 1, 2013] by September 1, 2013.
