R307. Environmental Quality, Air Quality.

Rule R307-348. Magnet Wire Coatings.

As in effect on July 1, 2019

Table of Contents

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.
