Solvent Cleaning

Change in Proposed Rule

DAR File No.: 41809
Filed: 10/05/2017 11:30:58 AM

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 R307-304 as a result of public comments. These changes include: adding an exemption for materials for solvent cleaning operations to the compliance schedule, adding exemptions for solvent cleaning in laboratory tests, analysis, research, and development projects as well as cleaning of solar cells, laser hardware, scientific instruments, and high-precision optics, clarifying definition for solvent cleaning; and adding VOC limits for advanced composites manufacturing and baby and child care diapers manufacturing. (EDITOR'S NOTE: The original proposed new rule 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 98. Underlining in the rule below indicates text that has been added since the publication of the proposed new rule mentioned above; strike-out indicates text that has been deleted. You must view the CPR and the proposed new rule 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 extension of the exemptions may lead to a savings to 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: added an exemption for materials for solvent cleaning operations to the compliance schedule; added exemptions for solvent cleaning in laboratory tests, analysis, research, and development projects, as well as cleaning of solar cells, laser hardware, scientific instruments, and high-precision optics; and clarified the definition for solvent cleaning do not result in additional compliance costs because requirements of the rule otherwise remain unchanged. The change to add VOC limits for advanced composites manufacturing and baby and child care diapers manufacturing are to provide clarification that these industries are also regulated and were included in the original rule cost analysis.

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

The extension of the exemptions may lead to a savings for businesses; however, it is difficult to determine the amount of the savings to be realized. The other changes will have no fiscal impact on any businesses because the changes do not modify any of the existing requirements within the rule.

R307. Environmental Quality, Air Quality.

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, minus exempt materials, for solvent cleaning operations.

(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 , minus exempt materials, for solvent cleaning operations.

 

R307-304-3. Exemptions.

(1) The requirements of R307-304 do not apply to the operations that are [regulated]subject to [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.]Solvent cleaning in laboratory tests and analysis and research and development projects.

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

(8) Cleaning solvents that are defined as a consumer product in R307-357 are exempt from R307-304 and are regulated under the requirements in R307-357.

(9) Cleaning of solar cells, laser hardware, scientific instruments, and high-precision optics.

 

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. Solvent cleaning does not include degreasing operations subject to R307-335.

"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).
