NR 465.42(8) (8) “Cleaning material” means a solvent used to remove contaminants and other materials, such as dirt, grease, oil and dried or wet coating, from a substrate before or after coating application or from equipment associated with a coating operation, such as spray booths, spray guns, racks, tanks and hangers. Thus, it includes any cleaning material used on substrates or equipment or both.

NR 465.42(9) (9) “Coating” means a material applied to a substrate for decorative, protective or functional purposes. Coating materials include paints, sealants, liquid plastic coatings, caulks, inks, adhesives and masking agents. Decorative, protective or functional materials that consist only of protective oils for metal, acids, bases, or any combination of these substances, or paper film or plastic film which may be pre-coated with an adhesive by the film manufacturer, are not considered coatings for the purposes of this subchapter. A liquid plastic coating means a coating made from fine particle-size polyvinyl chloride in solution, also referred to as a plastisol.

NR 465.42(10) (10) “Coating operation” means equipment used to apply cleaning materials to a substrate to prepare it for coating application or to remove dried coating; to apply coating to a substrate and to dry or cure the coating after application; or to clean coating operation equipment. A single coating operation may include any combination of these types of equipment, but always includes at least the point at which a given quantity of coating or cleaning material is applied to a given part and all subsequent points in the affected source where organic HAP are emitted from the specific quantity of coating or cleaning material on the specific part. There may be multiple coating operations in an affected source. Coating application with hand-held, non-refillable aerosol containers, touch-up markers or marking pens is not a coating operation for the purposes of this subchapter.

NR 465.42(26) (26) “Magnet wire coatings”, commonly referred to as “magnet wire enamels”, are applied to a continuous strand of wire which will be used to make turns, or windings, in electrical devices such as coils, transformers or motors. Magnet wire coatings provide high dielectric strength and turn-to-turn conductor insulation. This allows the turns of an electrical device to be placed in close proximity to one another which leads to increased coil effectiveness and electrical efficiency.

NR 465.42(27) (27) “Magnet wire coating machine” means equipment which applies and cures magnet wire coatings.

NR 465.42(28) (28) “Manufacturer’s formulation data” means data on a material, such as a coating, that are supplied by the material manufacturer based on knowledge of the ingredients used to manufacture that material, rather than based on testing of the material with the test methods specified in s. NR 465.46 (2). Manufacturer’s formulation data may include information on density, organic HAP content, volatile organic matter content and coating solids content.

NR 465.42(29) (29) “Mass fraction of organic HAP” means the ratio of the mass of organic HAP to the mass of a material in which it is contained, expressed as kg (lb) of organic HAP per kg (lb) of material.

NR 465.42(32) (32) “Organic HAP content” means the mass of organic HAP emitted per volume of coating solids used for a coating calculated using Equation 2 of s. NR 465.46 (2). The organic HAP content is determined for the coating in the condition it is in when received from its manufacturer or supplier and does not account for any alteration after receipt. For reactive adhesives in which some of the HAP react to form solids and are not emitted to the atmosphere, organic HAP content is the mass of organic HAP that is emitted, rather than the organic HAP content of the coating as it is received.

NR 465.42(33) (33) “Permanent total enclosure” or “PTE” means a permanently installed enclosure that meets the criteria of Method 204 in 40 CFR part 51, Appendix M, incorporated by reference in s.

NR 465.42(34) (34) “Personal watercraft” means a boat which uses an inboard motor powering a water jet pump as its primary source of motive power and which is designed to be operated by a person or persons sitting, standing or kneeling on the vessel, rather than in the conventional manner of sitting or standing inside the vessel.

NR 465.42(35) (35) “Protective oil” means an organic material that is applied to metal for the purpose of providing lubrication or protection from corrosion without forming a solid film. This definition of protective oil includes lubricating oils, evaporative oils, including those that evaporate completely, and extrusion oils. Protective oils used on miscellaneous metal parts and products include magnet wire lubricants and soft temporary protective coatings that are removed prior to installation or further assembly of a part or component.

NR 465.42(36) (36) “Reactive adhesive” means adhesive systems composed, in part, of volatile monomers that react during the adhesive curing reaction, and, as a result, do not evolve from the film during use. These volatile components instead become integral parts of the adhesive through chemical reaction. At least 70% of the liquid components of the system, excluding water, react during the process.

NR 465.42(37) (37) “Research or laboratory facility” means a facility whose primary purpose is for research and development of new processes and products, that is conducted under the close supervision of technically trained personnel, and is not engaged in the manufacture of final or intermediate products for commercial purposes, except in a de minimis manner.

NR 465.42(38) (38) “Responsible official” has the meaning given in s. NR 400.02 (136).

NR 465.42(39) (39) “Rubber-to-metal coatings” are coatings that contain heat-activated polymer systems in either solvent or water that, when applied to metal substrates, dry to a non-tacky surface and react chemically with the rubber and metal during a vulcanization process.

NR 465.43(1)(c) (c) If your facility’s surface coating operations meet the applicability criteria of more than one of the sub-category emission limits specified in par. (a) or (b), you may comply separately with each sub-category emission limit or comply using one of the alternatives in subd. 1. or 2.

NR 465.43(1)(c)1. 1. If the general use or magnet wire surface coating operations subject to only one of the emission limits specified in par. (a) 1. or 3. or (b) 1. or 3. account for 90% or more of the surface coating activity at your facility, then compliance with that one emission limit in this subchapter for all surface coating operations constitutes compliance with the other applicable emission limits. You shall use liters (gallons) of solids used as a measure of relative surface coating activity over a representative period of operation. You may estimate the relative volume of coating solids used from parameters other than coating consumption and volume solids content. The determination of predominant activity shall accurately reflect current and projected coating operations and shall be verifiable through appropriate documentation. The use of parameters other than coating consumption and volume solids content shall be approved by the administrator. You may use data for any reasonable time period of at least one year in determining the relative amount of coating activity, as long as they represent the way the source will continue to operate in the future and are approved by the administrator. You shall determine the predominant activity at your facility and submit the results of that determination with the initial notification required by s. NR 465.45 (1) (b). Additionally, you shall determine the facility’s predominant activity annually and include the determination in the next semi-annual compliance report required by s. NR 465.45 (2) (a).

NR 465.43 Note Note: An example of parameters other than coating consumption and mass solids content for estimating the relative mass of coating solids used would be design specifications for the parts or products coated and the number of items produced.

NR 465.43(1)(c)2. 2. You may calculate and comply with a facility-specific emission limit as described in subd. 2. a. to c. If you elect to comply using the facility-specific emission limit alternative, then compliance with the facility-specific emission limit and the emission limits specified in pars. (a) and (b) for all surface coating operations constitutes compliance with this and other applicable surface coating NESHAP. In calculating a facility-specific emission limit, you shall include coating activities that meet the applicability criteria of the other sub-categories and constitute more than one percent of total coating activities. Coating activities that meet the applicability criteria of other surface coating NESHAP but comprise less than one percent of coating activities need not be included in the determination of predominant activity but shall be included in the compliance calculation.

NR 465.43(1)(c)2.a. a. You are required to calculate the facility-specific emission limit for your facility when you submit the notification of compliance status required in s. NR 465.45 (1) (c), and on a monthly basis afterward using the coating data for the relevant 12-month compliance period.

NR 465.43(1)(c)2.b. b. Use Equation 1 of this subsection to calculate the facility-specific emission limit for your surface coating operations for each 12-month compliance period:

(Equation 1)

where:

Facility-specific emission limit is the facility-specific emission limit for each 12-month compliance period, kg (lb) of organic HAP per kg (lb) of coating solids used

Limiti is the new source or existing source emission limit as specified in s. NR 465.43 (1) applicable to coating operation, i, included in the facility-specific emission limit, converted to kg (lb) of organic HAP per kg (lb) of coating solids used, if the emission limit is not already in those units. All emission limits included in the facility-specific emission limit shall be in the same units.

Solidsi is the liters (gallons) of solids used in coating operation, i, in the 12-month compliance period that is subject to emission limit, i, as specified in s. NR 465.43 (1). You may estimate the volume of coating solids used from parameters other than coating consumption and volume solids content, such as design specifications for the parts or products coated and the number of items produced. The use of parameters other than coating consumption and volume solids content shall be approved by the administrator.

n is the number of different coating operations included in the facility-specific emission limit

NR 465.43(1)(c)2.c. c. If you need to convert an emission limit in another surface coating NESHAP from kg (lb) of organic HAP per kg (lb) of coating solids used to kg (lb) of organic HAP per liter (gallon) of coating solids used, you shall use the default solids density of 1.26 kg of solids per liter of coating solids (10.5 lb of solids per gallon of coating solids).

NR 465.43(2) (2) What are my options for meeting the emission limits? You shall include all coatings, thinners and other additives, and cleaning materials used in the affected source when determining whether the organic HAP emission rate is equal to or less than the applicable emission limit in sub.
