Rule R307-348

Magnet Wire Coatings

Notice of Proposed Rule

(New Rule)

DAR File No.: 36730
Filed: 09/06/2012 04:51:49 PM

RULE ANALYSIS

Purpose of the rule or reason for the change:

In 2006, EPA tightened the 24-hour PM2.5 national ambient air quality standard from 65 to 35 micrograms per cubic meter. Currently, seven Utah counties have been found by EPA to not meet this standard. Magnet wire coating operations emit volatile organic compounds (VOCs), which are precursors to the formation of PM2.5. This rule for the PM2.5 State Implementation Plan will lower VOCs that are emitted from magnet wire coating operations, as well as clarify regulatory requirements to the industry.

Summary of the rule or change:

This rule applies to magnet wire coating operations, including related cleaning activities, that have the potential to emit 2.7 tons of volatile organic compounds (VOC) per year and that are located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, and Weber counties. The rule establishes reasonably available control technology requirements to reduce VOC emissions. Owners and operators have the option to reduce VOCs by applying coatings with the VOC limits established in the rule or to use add-on controls to achieve at least a 90% VOC reduction. During the public comment period, the Air Quality Board is requesting public input on the appropriateness of applying this rule in Tooele and Box Elder counties.

State statutory or constitutional authorization for this rule:

• Subsection 19-2-104(1)(a)

Anticipated cost or savings to:

the state budget:

The majority of the requirements in this rule were already found in the Utah Air Quality rule, Rule R307-340, which has been proposed to be repealed. Therefore, there are no anticipated costs or savings to the state budget. (DAR NOTE: The proposed repeal of Rule R307-340 is under DAR No. 36725 is this issue, October 1, 2012, of the Bulletin.)

local governments:

The majority of the requirements in this rule were already found in the Utah Air Quality rule, Rule R307-340, which has been proposed to be repealed. Therefore, there are no anticipated costs or savings to local government.

small businesses:

Anticipated cost to sources is $6,560 per ton VOC removed.

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

This rule applies to fabric and vinyl coatings operations that emit 2.7 tons of VOC per year. There are no anticipated costs or savings to persons other than small businesses, businesses, or local government entities.

Compliance costs for affected persons:

The compliance cost to implement the requirements of this rule is approximately $6,560 per ton VOC removed.

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

The cost to business to comply with this rule is approximately $6,560 per ton VOC removed.

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.

 

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 VOCs in excess of 0.20 kilograms per liter of coating (1.7 pounds per gallon), excluding water, 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 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;

(b) Minimize spills of VOC-containing coatings and cleaning materials;

(c) Clean up spills immediately;

(d) Convey any coatings, thinners, and cleaning materials in closed containers or pipes;

(e) Close mixing vessels that contain VOC coatings and other materials except when specifically in use; and

(f) Minimize usage of solvents during cleaning of storage, mixing, and conveying equipment.

(2) The owner or operator shall maintain records from the manufacturer that demonstrate compliance with the emission standards of R307-348-4.

 

R307-348-6. Optional Add-On Controls.

(1) The owner or operator may install and maintain an

incinerator provided that the emission control device will attain at least 90% efficiency performance.

(2) The owner or operator of a control device shall provide certification from the manufacturer that the emission control system will attain required efficiency performance.

(3) Emission control systems shall be operated and maintained in accordance with the manufacturer recommendations. The owner or operator shall maintain for a minimum of two years records of operating and maintenance sufficient to demonstrate that the equipment is being operated and maintained in accordance with the manufacturer recommendations.

 

R307-348-7. Compliance Schedule.

(1) All sources in Davis and Salt Lake counties are subject to this rule as of the effective date of this rule.

(2) Sources in Box Elder, Cache, Utah, Tooele, and Weber counties shall be in compliance with this rule by January 1, 2014.
