Magnet Wire Coatings

Change in Proposed Rule

DAR File No.: 41826
Filed: 10/05/2017 11:34:48 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:

Two changes were made in Rule R307-348 as a result of public comments. These changes include adding clarification that operations covered by Department of Defense military technical data and performed by the United States Armed Forces are exempt from Rule R307-348; and adding work practice for solvent cleaning operations. (EDITOR'S NOTE: The original proposed amendment 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 121. 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 CPR and the proposed amendment 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:

These changes would not result in additional costs or savings to small businesses.

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, the exemption for operations covered by Department of Defense military technical data and performed by the United States Armed Forces, and work practice for solvent cleaning operations, do not result in additional compliance costs because the requirements of the rule otherwise remain unchanged.

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

The changes will have no fiscal impact on any businesses because the changes do not modify any of the existing requirements within in the rule.

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 magnet wire coating operations.

 

R307-348-2. Applicability.

R307-348 applies to sources that emit 2 tons per year or

more of VOC emissions, including related cleaning activities, that are located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah or Weber counties. Operations that are exclusively covered by Department of Defense military technical data and performed by the United States Armed Forces are exempt from the requirements of R307-348.

 

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. VOC Content Limit.

No owner or operator shall apply coatings with a VOC content greater than 200 grams VOC per liter (1.7 pounds per gallon), excluding water, and exempt solvents (compounds not classified as VOCs as defined in R307-101-2), unless the owner or operator uses an add-on control device as specified in R307-348-6.

 

R307-348-5. Work Practices.

(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) Solvent cleaning operations shall be performed using cleaning materials having a VOC composite vapor pressure no greater than 1 mm Hg at 20 degrees Celsius, unless an add-on control device is used as specified in R307-348-6.

 

R307-348-6. Add-On Control Systems Operations.

(1) If an add-on control system is used it must be installed, operated, and maintained in accordance with manufacturer recommendations.

(a) An add-on control device must have a 90% or greater capture and control efficiency rating. Efficiency must be determined using EPA approved methods as follows:

(i) Capture efficiency must be determined according to EPA's "Guidelines for Determining Capture Efficiency," January 9, 1995 and 40 C.F.R. Parts 51, Appendix M, Methods 204-204F, as applicable.

(ii) Control efficiency must be determined using test methods in Appendices A-1, A-6, and A-7 to 40 C.F.R. Part 60, for measuring flow rates, total gaseous organic concentrations, or emissions of exempt compounds, as applicable.

(iii) An alternative test method may be substituted for the preceding test methods after review and approval by the EPA Administrator.

 

R307-348-7. Recordkeeping.

(1) The owner or operator shall maintain records of the following:

(a) Records that demonstrate compliance with R307-348. Records must include, but are not limited to, inventory and product data sheets of all coatings and solvents subject to R307-348.

(b) If an add-on control device is used, records of key system parameters necessary to ensure compliance with R307-348-6.

(i) Key system parameters include, but are not limited to, temperature, pressure, flow rates, and an inspection schedule.

(ii) Key inspection parameters must be in accordance with the manufacturer's recommendations, and as required to demonstrate operations are providing continuous emission reduction from the source during all periods that the operations cause emissions from the source.

(2) All records must be maintained for a minimum of 2 years.

(3) Records must be made available to the director upon request.
