NR 465.38(1)(b)3.3. 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 465.31 (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 mass of coatings 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 results of emission capture system and add-on control device performance tests conducted according to subs. (5), (6) and (7); results of liquid-liquid material balances conducted according to sub. (2) (j); 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 465.33 (1); the operating limits established during the performance tests and the results of the continuous parameter monitoring required by sub. (9); and documentation of whether you developed and implemented the work practice plan required by s. NR 465.33 (4).

NR 465.38(1)(c)(c) You are not required to conduct an initial performance test to determine capture efficiency or destruction efficiency of a capture system or control device if you receive approval to use the results of a performance test that has been previously conducted on that capture system or control device. Any previous tests shall meet the conditions described in subds. 1. to 3.

NR 465.38(2)(a)(a) General. You may use the emission rate with add-on controls option for any coating operation, for any group of coating operations in the affected source, or for all of the coating operations in the affected source. You may include both controlled and uncontrolled coating operations in a group for which you use this option. You shall use either the compliant material option in s. NR 465.33 (2) (a) or the emission rate without add-on controls option in s. NR 465.33 (2) (b) for any coating operation in the affected source for which you do not use the emission rate with add-on controls option. To demonstrate initial compliance, the coating operations for which you use the emission rate with add-on controls option shall meet the applicable emission limits in s. NR 465.33 (1), (3) and (4). You shall conduct a separate initial compliance demonstration for each general use, thermoplastic olefin, automotive lamp and assembled on-road vehicle coating operation, unless you are demonstrating compliance with a predominant activity or facility-specific emission limit as provided in s. NR 465.33 (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 this subsection, do not include any coatings, thinners or other additives, or cleaning materials used on coating operations for which you use the compliant material option or the emission rate without add-on controls option. You do not need to re-determine the mass of organic HAP in coatings, thinners or other additives, or cleaning materials that have been reclaimed onsite, 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 coatings operations for which you use the emission rate with 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. That is, the amount used may be calculated as the amount consumed to account for materials that are reclaimed.

NR 465.38(2)(b)(b) Compliance with operating limits. Except as provided in sub. (1) (a) 4., and except for solvent recovery systems for which you conduct liquid-liquid material balances according to the requirements of par. (j), you shall establish and demonstrate continuous compliance during the initial compliance period with the operating limits required by s. NR 465.33 (3), using the procedures specified in subs. (8) and (9).

NR 465.38(2)(c)(c) Compliance with work practice requirements. You shall develop, implement and document your implementation of the work practice plan required by s. NR 465.33 (4) during the initial compliance period, as specified in s. NR 465.35 (3).

NR 465.38(2)(d)(d) Compliance with emission limits. You shall follow the procedures in pars. (e) to (n) to demonstrate compliance with the applicable emission limit in s. NR 465.33 (1) for each affected source in each sub-category.

NR 465.38(2)(e)(e) Determine the mass fraction of organic HAP, density, volume used, and mass fraction of coating solids. Follow the procedures specified in s. NR 465.37 (2) (a) to (d) to determine the mass fraction of organic HAP, density and volume of each coating, thinner and other additive, and cleaning material used during each month; and the mass fraction of coating solids for each coating used during each month.

NR 465.38(2)(f)(f) Calculate the total mass of organic HAP emissions before add-on controls. Using Equation 1 of s. NR 465.37 (2), calculate the total mass of organic HAP emissions before add-on controls from all coatings, thinners and other additives, and cleaning materials used during each month in the coating operation or group of coating operations for which you use the emission rate with add-on controls option.

NR 465.38(2)(g)(g) Calculate the organic HAP emission reduction for each controlled coating operation. Determine the mass of organic HAP emissions reduced for each controlled coating operation during each month. The emission reduction determination quantifies the total organic HAP emissions that pass through the emission capture system and are destroyed or removed by the add-on control device. Use the procedures in par. (h) to calculate the mass of organic HAP emission reduction for each controlled coating operation using an emission capture system and add-on control device other than a solvent recovery system for which you conduct liquid-liquid material balances. For each controlled coating operation using a solvent recovery system for which you conduct a liquid-liquid material balance, use the procedures in par. (j) to calculate the organic HAP emission reduction.

NR 465.38(2)(h)(h) Calculate the organic HAP emission reduction for each controlled coating operation not using liquid-liquid material balance. Use the equations in this paragraph to calculate the organic HAP emission reduction for each controlled coating operation using an emission capture system and add-on control device other than a solvent recovery system for which you conduct liquid-liquid material balances. You shall assume zero efficiency for the emission capture system and add-on control device for any period of time a deviation specified in sub. (4) (c) or (d) occurs in the controlled coating operation, including a deviation during a period of startup, shutdown or malfunction, unless you have other data indicating the actual efficiency of the emission capture system and add-on control device and the use of these data is approved by the department.

NR 465.38 NoteNote: The calculation applies the emission capture system efficiency and add-on control device efficiency to the mass of organic HAP contained in the coatings, thinners and other additives, and cleaning materials that are used in the coating operation served by the emission capture system and add-on control device during each month. Equation 1 treats the materials used during a deviation as if they were used on an uncontrolled coating operation for the time period of the deviation.
