NR 465.46(1)(1) By what date must i conduct the initial compliance demonstration? You shall complete the initial compliance demonstration for the initial compliance period according to the requirements in sub. (2). The initial compliance period begins on the applicable compliance date specified in s. NR 465.41 (4) and ends on the last day of the 12th month following the compliance date. If the compliance date occurs on any day other than the first day of a month, then the initial compliance period extends through that month plus the next 12 months. The initial compliance demonstration includes the calculations according to sub. (2) and supporting documentation showing that during the initial compliance period, you used no coating with an organic HAP content that exceeded the applicable emission limit in s. NR 465.43 (1), and that you used no thinners or other additives, or cleaning materials that contained organic HAP as determined according to sub. (2) (a).

NR 465.46(2)(2) How do i demonstrate initial compliance with the emission limits? You may use the compliant material option for any individual coating operation, for any group of coating operations in the affected source or for all the coating operations in the affected source. You shall use either the emission rate without add-on controls option in s. NR 465.43 (2) (b) or the emission rate with add-on controls option in s. NR 465.43 (2) (c) for any coating operation in the affected source for which you do not use the compliant material option. To demonstrate initial compliance using the compliant material option, the coating operation or group of coating operations may not use any coating with an organic HAP content that exceeds the applicable emission limits in s. NR 465.43 (1) and may not use any thinner or other additive, or cleaning material that contains organic HAP as determined according to pars. (a) to (e). Any coating operation for which you use the compliant material option is not required to meet the operating limits or work practice standards required in s. NR 465.43 (3) and (4), respectively. You shall conduct a separate initial compliance demonstration for each general use, high performance, magnet wire, rubber-to-metal and extreme performance fluoropolymer coating operation unless you are demonstrating compliance with a predominant activity or facility-specific emission limit as provided in s. NR 465.43 (1) (c). If you are demonstrating compliance with a predominant activity or facility-specific emission limit, you shall demonstrate that all coating operations included in the predominant activity determination or calculation of the facility-specific emission limit comply with that limit. You shall meet all the requirements of this subsection. You shall use the procedures in pars. (a) to (e) on each coating, thinner, other additive and cleaning material in the condition it is in when it is received from its manufacturer or supplier and prior to any alteration. You do not need to redetermine the organic HAP content of coatings, thinners, other additives and cleaning materials that are reclaimed on-site, or reclaimed off-site if you have documentation showing that you received back the exact same materials that were sent off-site, and reused in the coating operation or operations for which you use the compliant material option, provided these materials in their condition as received were demonstrated to comply with the compliant material option.

NR 465.46(2)(a)2.2. ‘Method 24.’ For coatings, you may use Method 24 in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), to determine the mass fraction of nonaqueous volatile matter and use that value as a substitute for mass fraction of organic HAP. For reactive adhesives in which some of the HAP react to form solids and are not emitted to the atmosphere, you may use the alternative method contained in 40 CFR part 63, Subpart PPPP, Appendix A, incorporated by reference in s. NR 484.04 (24r), rather than Method 24. You may use the volatile fraction that is emitted, as measured by the alternative method in 40 CFR part 63, Subpart PPPP, Appendix A, as a substitute for the mass fraction of organic HAP.

NR 465.46(2)(a)4.4. ‘Information from the supplier or manufacturer of the material.’ You may rely on information other than that generated by the test methods specified in subds. 1. to 3., such as manufacturer’s formulation data, if it represents each organic HAP that is present at 0.1% by mass or more for OSHA-defined carcinogens as specified in 29 CFR 1910.1200(d)(4) and at 1.0% by mass or more for other compounds. For reactive adhesives in which some of the HAP react to form solids and are not emitted to the atmosphere, you may rely on manufacturer’s data that expressly states the organic HAP or volatile matter mass fraction emitted. If there is a disagreement between manufacturer’s information and results of a test conducted according to subds. 1. to 3., then the test method results will take precedence unless, after consultation, you demonstrate to the satisfaction of the department that the formulation data are correct.

NR 465.46(2)(a)5.5. ‘Solvent blends.’ Solvent blends may be listed as single components for some materials in data provided by manufacturers or suppliers. Solvent blends may contain organic HAP which shall be counted toward the total organic HAP mass fraction of the materials. When test data and manufacturer’s data for solvent blends are not available, you may use the default values for the mass fraction of organic HAP in these solvent blends listed in Table 2 or 3 of this subchapter. If you use the tables, you shall use the values in Table 2 for all solvent blends that match Table 2 entries according to the instructions for Table 2, and you may use Table 3 only if the solvent blends in the materials you use do not match any of the solvent blends in Table 2 and you know only whether the blend is aliphatic or aromatic. However, if the results of a test using Method 311 in 40 CFR part 63, Appendix A, incorporated by reference in s. NR 484.04 (25), indicate higher values than those listed on Table 2 or 3, the Method 311 results will take precedence unless, after consultation, you demonstrate to the satisfaction of the department that the formulation data are correct.

NR 465.46(2)(b)(b) Determine the volume fraction of coating solids for each coating. You shall determine the volume fraction of coating solids, in liters (gallons) of coating solids per liter (gallon) of coating, for each coating used during the compliance period by a test, by information provided by the supplier or the manufacturer of the material, or by calculation, as specified in subds. 1. to 4. If test results obtained according to subd. 1. do not agree with the information obtained under subd. 3. or 4., the test results will take precedence unless, after consultation, you demonstrate to the satisfaction of the department that the formulation data are correct.

NR 465.46(2)(b)1.1. ‘ASTM D2697-86 (1998) or ASTM D6093-97 (2003).’ You may use ASTM D2697-86 (1998) “Standard Test Method for Volume Nonvolatile Matter in Clear or Pigmented Coatings”, incorporated by reference in s. NR 484.10 (39e), or ASTM D6093-97 (2003) “Standard Test Method for Percent Volume Nonvolatile Matter in Clear or Pigmented Coatings Using a Helium Gas Pycnometer”, incorporated by reference in s. NR 484.10 (55m), to determine the volume fraction of coating solids for each coating. Divide the nonvolatile volume percent obtained with the methods by 100 to calculate volume fraction of coating solids.

Davg is the average density of volatile matter in the coating, grams (lb) of volatile matter per liter (gallon) of volatile matter, determined from test results using ASTM D1475-98 (2003) “Standard Test Method for Density of Liquid Coatings, Inks, and Related Products”, incorporated by reference in s. NR 484.10 (22), information from the supplier or manufacturer of the material, or reference sources providing density or specific gravity data for pure materials. If there is disagreement between ASTM Method D1475-98 (2003) test results and other information sources, the test results will take precedence unless, after consultation, you demonstrate to the satisfaction of the department that the formulation data are correct.

NR 465.46(2)(c)(c) Determine the density of each coating. Determine the density of each coating used during the compliance period from test results using ASTM D1475-98 (2003) “Standard Test Method for Density of Liquid Coatings, Inks, and Related Products”, incorporated by reference in s. NR 484.10 (22), information from the supplier or manufacturer of the material, or specific gravity data for pure chemicals. If there is disagreement between ASTM D1475-98 (2003) test results and the supplier’s or manufacturer’s information, the test results will take precedence unless, after consultation, you demonstrate to the satisfaction of the department that the formulation data are correct.
