Change in Proposed Rule

DAR File No.: 36730
Filed: 12/10/2012 12:39:32 PM

RULE ANALYSIS

Purpose of the rule or reason for the change:

During the public comment period, the Division of Air Quality (DAQ) received several comments from the EPA and the industry that resulted in the need to make substantive changes to the proposed rule.

Summary of the rule or change:

The applicability of the rule is changed to only apply to existing sources in Box Elder and Tooele counties as of 02/01/2013 that have the potential to emit 5 tons per year or more of VOC and to apply to new sources in Box Elder and Tooele counties as of 02/01/2013 that have the potential to emit 2.7 tons per year or more VOC. The rule still applies in Cache, Davis, Salt Lake, Utah, and Weber counties to sources that have the potential to emit 2.7 tons per year or more VOC. Language is added to Subsection R307-348-4(1) to clarify that exempt solvents are not included in the VOC coating content limits. Language is added to Subsection R307-348-5(2) to require that sources make records available to the director upon request. Subsection R307-348-6(2) is changed to clarify that the owner or operator of a magnet wire coatings operation shall provide documentation that the emission control system will attain the requirements of Section R307-348-6. (DAR NOTE: This change in proposed rule has been filed to make additional changes to a proposed new rule that was published in the October 1, 2012, issue of the Utah State Bulletin, on page 73. Underlining in the rule below indicates text that has been added since the publication of the proposed rule mentioned above; strike-out indicates text that has been deleted. You must view the change in proposed rule and the proposed new rule together to understand all of the changes that will be enforceable should the agency make this rule effective.)

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

local governments:

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

small businesses:

Because the rule's applicability to existing sources in Box Elder and Tooele counties is changed from sources with the potential to emit 2.7 tons per year VOC to sources with the potential to emit 5 tons per year VOC, the rule will apply to fewer sources in those counties, resulting in a savings of up to $8,528 per year per small source.

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

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

Compliance costs for affected persons:

Because the rule's applicability to existing sources in Box Elder and Tooele counties is changed from sources with the potential to emit 2.7 tons per year VOC to sources with the potential to emit 5 tons per year VOC, the rule will apply to fewer sources in those counties, resulting in a savings of up to $8,528 per year per small source.

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

Because the rule's applicability to existing sources in Box Elder and Tooele counties is changed from sources with the potential to emit 2.7 tons per year VOC to sources with the potential to emit 5 tons per year VOC, the rule will apply to fewer sources in those counties, resulting in a savings of up to $8,528 per year per small source.

R307. Environmental Quality, Air Quality.

R307-348. Magnet Wire Coatings.

R307-348-1. Purpose.

The purpose of this rule is to limit volatile organic compound (VOC) emissions from ovens of magnet wire coating operations.

 

R307-348-2. Applicability.

[R307-348 applies to magnet wire coating operations that have the potential to emit 2.7 tons per year of VOC and are located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber counties.](1) R307-348 applies to sources located in Cache, Davis, Salt Lake, 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, R307-348 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.

 

R307-348-3. Definitions.

The following additional definition applies to R307-348:

"Magnet wire coating" means the process of applying coating of electrical insulating varnish or enamel to aluminum or copper wire for use in electrical machinery.

 

R307-348-4. Emission Standards.

(1) No owner or operator of a magnet wire coating oven may cause, allow or permit discharge into the atmosphere of any VOC[s] in excess of 0.20 kilograms per liter of coating (1.7 pounds per gallon), excluding water, and exempt solvents (compounds not classified as VOCs) delivered to the coating applicator from magnet wire coating operations.

(a) Equivalency calculations for coatings shall be performed in units of pounds VOCs per gallon of solid rather than pounds VOCs per gallon of coating when determining compliance.

(b) The equivalent emission limit is 2.2 pounds VOCs per gallon solids.

(2) The emission limitations specified above shall be achieved by:

(a) The application of low solvent content coating technology; or

(b) The use of an add-on control device on magnet wire coating ovens as specified in R307-348-6.

 

R307-348-5. Work Practices and Recordkeeping.

(1) The owner or operator shall:

(a) Store all VOC-containing coatings and cleaning materials in closed containers;
