NR 465.26(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 465.21 (4) and ends on the last day of the first full month after 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 the end of that month plus the next month. The initial compliance demonstration includes the determination 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 465.23 (1), and that you used no thinners or cleaning materials that contained organic HAP.

NR 465.26(2)(2) How do I demonstrate initial compliance with the emission limitations?. 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 or the emission rate with add-on controls option for any coating operation in the affected source for which you do not use this 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 limit in s. NR 465.23 (1) and may not use any thinner or cleaning material that contains organic HAP, as determined according to this section during the initial compliance period. Any coating operation or operations for which you use the compliant material option is not required to meet the operating limits or work practice standards required in s. NR 465.23 (3) and (4), respectively. To demonstrate initial compliance with the emission limitations using the compliant material option, you shall meet all the requirements of this subsection for the coating operation or operations using this option. You shall use the procedures in this subsection on each coating, thinner 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 HAP content of coatings, thinners or cleaning materials that have been reclaimed onsite 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. You shall comply with the following requirements and procedures except that if the mass fraction of organic HAP of a coating equals zero, determined according to par. (a), and you use the compliant material option, you are not required to comply with pars. (b) and (c) for that coating:

NR 465.26(2)(a)4.4. Use information other than that generated by the test methods specified in subds. 1. to 3., such as manufacturer’s formulation data, if they represent 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 organic HAP compounds. If there is a disagreement between information relied on under this subdivision and results of a test conducted according to subds. 1. to 3., the test method results will take precedence.

NR 465.26(2)(a)5.5. When test data and manufacturer’s data for solvent blends are not available, use the default values for mass fraction of organic HAP for these solvent blends listed in Table 2 or 3 of this subchapter. You shall use the values in Table 2 of this subchapter for all solvent blends that match Table 2 entries, and you may only use Table 3 of this subchapter if the solvent blends in the materials you use do not match any of the solvent blends in Table 2 of this subchapter, and you only know whether the blend is aliphatic or aromatic. However, if the results of a Method 311 test indicate higher values than those listed in Table 2 or 3 of this subchapter, the Method 311 results will take precedence. 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.

NR 465.26(2)(b)1.1. Use ASTM Method D2697-86 (1998), “Standard Test Method for Volume Nonvolatile Matter in Clear or Pigmented Coatings”, or ASTM Methods D6093-97, “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 (39e) and (55m), respectively, to determine the volume percent of coating solids for each coating. Divide the nonvolatile volume percent obtained with the methods by 100 to calculate volume fraction of coating solids.
