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.

(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.

par. (a). You shall keep all records required by
s. NR 465.45 (3) and
(4). As part of the notification of compliance status required in
s. NR 465.45 (1), you shall identify the coating operations for which you used the compliant material option and submit a statement that the coating operations were in compliance with the emission limits in
s. NR 465.43 (1) during the initial compliance 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 thinners or other additives, or cleaning materials that contained organic HAP, determined according to the procedures in
par. (a).
NR 465.46(3)

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) by using the compliant material option specified in this section, the use of any coating, thinner or other additive, or cleaning material that does not meet the criteria specified in
par. (a) is a deviation from the emission limits in
s. NR 465.43 (1) that shall be reported as specified in
s. NR 465.45 (1) (c) 6. and
(2) (a) 5.
NR 465.46(3)(c)

(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.

", 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.

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.
