Solvent Cleaning

Notice of Proposed Rule

(New Rule)

DAR File No.: 41809
Filed: 06/14/2017 08:58:07 AM

RULE ANALYSIS

Purpose of the rule or reason for the change:

The purpose of this rule is to create a new rule that regulates industrial solvent cleaning operations and general solvent use. These activities were previously regulated under Rule R307-335. This new rule is being proposed to achieve further volatile organic compound (VOC) emissions reductions that are required by the Clean Air Act and the Serious Area PM2.5 requirements. (Editor's Note: The proposed amendment to Rule R307-335 is under Filing No. 41810 in this issue, July 1, 2017, of the Bulletin.)

Summary of the rule or change:

The proposed rule will contain the industrial solvent cleaning requirements that were previously found in Rule R307-335. The applicability threshold of this rule will also be lower than the previous version found in Rule R307-335. The rule will also provide a vapor pressure limit that can be used by regulated entities as an alternative to the VOC content limits in the rule.

Statutory or constitutional authorization for this rule:

• Section 19-2-104

Anticipated cost or savings to:

the state budget:

There are no anticipated costs or saving to the state budget because the rule is regulating solvent cleaning operations that use 55 gallons or more of VOC containing solvent products a year. This does not describe the state.

local governments:

There are no anticipated costs or saving to local governments because the rule is regulating solvent cleaning operations that use 55 gallons or more of VOC containing solvent products a year. This does not describe local governments.

small businesses:

There are no anticipated costs or saving to small businesses. Small businesses that use VOC containing solvent products for solvent cleaning operations and general solvent usage are likely already regulated under Rule R307-335. The content limits have not changed. Due to the lower threshold for applicability, more people may be regulated by this rule than are currently regulated under Rule R307-335. The cost per ton of emissions reduced for these additional sources will be about $4.36 per ton of VOCs removed.

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

There will likely be no costs or savings to "other persons" because the applicability threshold is set at a level that is meant to exclude all hobbyists that are not part of a business or governmental entity.

Compliance costs for affected persons:

The compliance costs will be the same as they were when these requirements were originally included in Rule R307-335. The cost per ton of VOC emissions reduced as a result of this rule will be about $4.36. A greater amount of product used will result in a greater total cost.

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

After conducting a thorough analysis, it was determined that this proposed rule will not result in a fiscal impact to businesses. This is because the source of any cost would be the difference in the price between compliant and non-compliant solvents. The difference in this cost is nominal. In addition to the nominal price difference, the rule provides more flexibility for sources to choose what type of solvent they would like to use. This is done in the form of a vapor pressure limit alternative that can be used in place of the mass based content limit currently in the rule. The nominal price difference, combined with the opportunity to use a wider variety of products, means that the rule amendment will not have a fiscal impact on businesses.

R307-304. Solvent Cleaning.

R307-304-1. Purpose.

The purpose of R307-304 is to limit volatile organic compound (VOC) emissions from solvent cleaning operations.

 

R307-304-2. Applicability.

(1) R307-304 applies to solvent cleaning operations within Box Elder, Cache, Davis, Salt Lake, Tooele, Utah or Weber counties.

(2) Before September 1, 2018, R307-304 applies to an owner or operator using 720 gallons or more a year of VOC containing solvent products.

(3) Effective September 1, 2018, R307-304 shall apply to an owner or operator using 55 gallons or more a year of VOC containing solvent products.

 

R307-304-3. Exemptions.

(1) The requirements of R307-304 do not apply to the operations that are regulated under R307-342 through R307-347 and R307-349 through R307-355.

(2) Shipbuilding and repair and fiberglass boat manufacturing materials.

(3) Operations that are exclusively covered by Department of Defense military technical data and performed by a Department of Defense contractor and/or on site at installations owned and/or operated by the United States Armed Forces are exempt from the requirements of R307-304.

(4) Janitorial cleaning.

(5) Graffiti removal.

(6) Waste solvent from analytical laboratories.

(7) Cleaning with aerosol products not greater than 16 fluid ounces.

 

R307-304-4. Definitions.

The following additional definitions apply to R307-304:

"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.

"Janitorial cleaning" means the cleaning of building floors, ceilings, walls, windows, doors, stairs, bathrooms, office surfaces and equipment.

 

R307-304-5. VOC Content Limits.

(1) No person shall use solvent products with a VOC content greater than the amounts specified in Table 1, unless the owner or operator uses an add-on control device as specified in R307-304-7 or the alternative method in R307-304-5(2).
