(1) APPLICABILITY AND DESIGNATION OF AFFECTED FACILITY.

(a) The affected facilities to which the provisions of this section apply are:
1. Each coating operation; and

2. Each piece of coating mix preparation equipment.

(b) Any new coating operation that utilizes less than 38 m3 of solvent or any modified or reconstructed coating operation that utilizes less than 370 m3 of solvent for the manufacture of magnetic tape per calendar year is subject only to the requirements of subs. (5) (a) and (8) (b) and (c). If the amount of solvent utilized for the manufacture of magnetic tape equals or exceeds these amounts in any calendar year, the facility is subject to sub. (3) and all other paragraphs of this section. Once a facility has become subject to sub. (3) and all other paragraphs of this section, it shall remain subject to those requirements regardless of changes in annual solvent utilization.

(c) This section applies to any affected facility for which construction, modification or reconstruction begins after January 22, 1986.

(2) DEFINITIONS, SYMBOLS AND CROSS REFERENCE TABLES.

(a) All terms used in this section that are not defined as follows have the meaning given to them in s. NR 440.02.
1. "Base film" means the substrate that is coated to produce magnetic tape.

2. "Capture system" means any device or combination of devices that contains or collects an airborne pollutant and directs it into a duct.

3. "Coating applicator" means any apparatus used to apply a coating to a continuous base film.

4. "Coating mix preparation equipment" means all mills, mixers, holding tanks, polishing tanks and other equipment used in the preparation of the magnetic coating formulation but does not include those mills that do not emit VOC because they are closed, sealed and operated under pressure.

5. "Coating operation" means any coating applicator, flashoff area and drying oven located between a base film unwind station and a base film rewind station that coat a continuous base film to produce magnetic tape.

6. "Common emission control device" means a control device controlling emissions from the coating operation as well as from another emission source within the plant.

7. "Concurrent" means construction of a control device is commenced or completed within the period beginning 6 months prior to the date construction of affected coating mix preparation equipment commences and ending 2 years after the date construction of affected coating mix preparation equipment is completed.

8. "Control device" means any apparatus that reduces the quantity of a pollutant emitted to the air.

9. "Cover" means, with respect to coating mix preparation equipment, a device that lies over the equipment opening to prevent VOC from escaping and that meets the requirements found in sub. (3) (e) 1. to 5.

10. "Drying oven" means a chamber in which heat is used to bake, cure, polymerize or dry a surface coating.

11. "Equivalent diameter" means 4 times the area of an opening divided by its perimeter.

12. "Flashoff area" means the portion of a coating operation between the coating applicator and the drying oven where solvent begins to evaporate from the coated base film.

13. "Magnetic tape" means any flexible substrate that is covered on one or both sides with a coating containing magnetic particles and that is used for audio or video recording or information storage.

14. "Natural draft opening" means any opening in a room, building or total enclosure that remains open during operation of the facility and that is not connected to a duct in which a fan is installed. The rate and direction of the natural draft across such an opening is a consequence of the difference in pressures on either side of the wall containing the opening.

15. "Nominal 1-month period" means a calendar month or, if established prior to the performance test, a similar monthly time period, for example, 30-day month or accounting month.

16. "Temporary enclosure" means a total enclosure that is constructed for the sole purpose of measuring the fugitive emissions from an affected facility. A temporary enclosure shall be constructed and ventilated, through stacks suitable for testing, so that it has minimal impact on the performance of the permanent capture system. A temporary enclosure will be assumed to achieve total capture of fugitive VOC emissions if it conforms to the requirements found in sub. (4) (b) 5. a. and if all natural draft openings are at least 4 duct or hood equivalent diameters away from each exhaust duct or hood. Alternatively, the owner or operator may apply to the administrator for approval of a temporary enclosure on a case-by-case basis.

17. "Total enclosure" means a structure that is constructed around a source of emissions so that all VOC emissions are collected and exhausted through a stack or duct. With a total enclosure, there will be no fugitive emissions, only stack emissions. The only openings in a total enclosure are forced makeup air and exhaust ducts and any natural draft openings such as those that allow raw materials to enter and exit the enclosure for processing. All access doors or windows are closed during routine operation of the enclosed source. Brief, occasional openings of such doors or windows to accommodate process equipment adjustments are acceptable, but, if such openings are routine or if an access door remains open during the entire operation, the access door shall be considered a natural draft opening. The average inward face velocity across the natural draft openings of the enclosure shall be calculated including the area of such access doors. The drying oven itself may be part of the total enclosure. A permanent enclosure that meets the requirements found in sub. (4) (b) 5. a. is assumed to be a total enclosure. The owner or operator of a permanent enclosure that does not meet the requirements may apply to the department for approval of the enclosure as a total enclosure on a case-by-case basis. Such approval shall be granted upon a demonstration to the satisfaction of the department that all VOC emissions are contained and vented to the control device.

18. "Utilize" refers to the use of solvent that is delivered to coating mix preparation equipment for the purpose of formulating coatings to be applied on an affected coating operation and any other solvent, for example, dilution solvent, that is added at any point in the manufacturing process.

20. "Volatile organic compounds" or `VOC` means any organic compounds that participate in atmospheric photochemical reactions or that are measured by Method 18, 24, 25 or 25A or an equivalent or an alternative method as defined in s. NR 440.02(5).

The container shall be tightly sealed immediately after the sample is taken. Any solvent or other VOC added after the sample is taken shall be measured and accounted for in the calculations that use Method 24 results.

(b) Method 18, 25 or 25A, as appropriate to the conditions at the site, is used to determine VOC concentration. The owner or operator shall submit notice of the intended test method to the administrator for approval along with the notification of the performance test required under s. NR 440.08(2).
