NR 465.46(3)(a)(a) For each compliance period, to demonstrate continuous compliance, you may not use any coating for which the organic HAP content, determined using Equation 2 of sub. (2) (d), exceeds the applicable emission limit in s. NR 465.43 (1), and you may not use any thinner or other additive, or cleaning material that contains organic HAP, determined according to sub. (2) (a). A compliance period consists of 12 months. Each month, after the end of the initial compliance period described in sub. (1), is the end of a compliance period consisting of that month and the preceding 11 months. If you are complying with a facility-specific emission limit under s. NR 465.43 (1) (c) 2., you shall also perform the calculation using Equation 1 of s. NR 465.43 (1) (c) 2. on a monthly basis using the data from the previous 12 months of operation.

NR 465.46(3)(c)(c) As part of each semiannual compliance report required by s. NR 465.45 (2), you shall identify the coating operations for which you used the compliant material option. If there were no deviations from the applicable emission limit in s. NR 465.43 (1), submit a statement that the coating operations were in compliance with the emission limits during the reporting period because you used no coatings for which the organic HAP content exceeded the applicable emission limit in s. NR 465.43 (1), and you used no thinner, other additive or cleaning material that contained organic HAP, determined according to sub. (2) (a).

NR 465.47(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 of 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 the end of that month plus the next 12 months. You shall determine the mass of organic HAP emissions and volume of coating solids used each month and then calculate an organic HAP emission rate at the end of the initial compliance period. The initial compliance demonstration includes the calculations according to sub. (2) and supporting documentation showing that during the initial compliance period the organic HAP emission rate was equal to or less than the applicable emission limit in s. NR 465.43 (1).

NR 465.47(2)(2) How do i demonstrate initial compliance with the emission limits? You may use the emission rate without add-on controls 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 compliant material option in s. NR 465.43 (2) (a) 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 emission rate without add-on controls option. To demonstrate initial compliance using the emission rate without add-on controls option, the coating operation or group of coating operations shall meet the applicable emission limit in s. NR 465.43 (1), but is not required to meet the operating limits or work practice standards in s. NR 465.43 (3) and (4). You shall conduct a separate initial compliance demonstration for each general use, 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. When calculating the organic HAP emission rate according to pars. (a) to (h), do not include any coatings, thinners, other additives or cleaning materials used on coating operations for which you use the compliant material option specified in s. NR 465.43 (2) (a) or the emission rate with add-on controls option specified in s. NR 465.43 (2) (c) You do not need to redetermine the mass of organic HAP in coatings, thinners or other additives, or cleaning materials that have been 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 emission rate without add-on controls option. If you use coatings, thinners or other additives, or cleaning materials that have been reclaimed on-site, the amount of each used in a month may be reduced by the amount of each that is reclaimed.

NR 465.47(2)(c)(c) Determine the density of each material. Determine the density of each liquid coating, thinner or other additive, and cleaning material used during each month 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 you are including powder coatings in the compliance determination, determine the density of powder coatings, using ASTM D5965-02 “Standard Test Methods for Specific Gravity of Coating Powders”, incorporated by reference in s. NR 484.10 (55i), or information from the supplier. If there is disagreement between ASTM Method D1475-98 (2003) or ASTM Method D5965-02 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. If you purchase materials or monitor consumption by weight instead of volume, you do not need to determine material density. Instead, you may use the material weight in place of the combined terms for density and volume in Equations 1A, 1B, 1C and 2 of this subsection.

NR 465.47(2)(d)(d) Determine the volume of each material used. Determine the volume in liters (gallons) of each coating, thinner, other additive, and cleaning material used during each month by measurement or usage records. If you purchase materials or monitor consumption by weight instead of volume, you do not need to determine the volume of each material used. Instead, you may use the material weight in place of the combined terms for density and volume in Equations 1A, 1B and 1C of this subsection.
