Section NR 465.37 - Compliance requirements for the emission rate without add-on controls option

(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 465.31(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 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 465.33(1).

(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 465.33(2) (a) or the emission rate with add-on controls option in s. NR 465.33(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 465.33(1), but is not required to meet the operating limits or work practice standards in s. NR 465.33(3) and (4). You shall conduct a separate initial compliance demonstration for each general use, TPO, 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 in s. NR 465.33(2) (a) or the emission rate with add-on controls option in s. NR 465.33(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. That is, the amount used may be calculated as the amount consumed to account for materials that are reclaimed.

(a)Determine the mass fraction of organic HAP for each material. Determine the mass fraction of organic HAP for each coating, thinner and other additive, and cleaning material used during each month according to the requirements in s. NR 465.36(2) (a).

(b)Determine the mass fraction of coating solids. Determine the mass fraction of coating solids, kg (lb) of coating solids per kg (lb) of coating, for each coating used during each month according to the requirements in s. NR 465.36(2) (b).

(c)Determine the density of each material. Determine the density of each liquid coating, thinner, 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 there is disagreement between ASTM D1475-98 (2003) 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.

(d)Determine the volume of each material used. Determine the volume, in liters or gallons, of each coating, thinner and 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, 1C and 2 of this subsection.

(e)Calculate the mass of organic HAP emissions.

1. The mass of organic HAP emissions is the combined mass of organic HAP contained in all coatings, thinners and other additives, and cleaning materials used during each month minus the organic HAP in certain waste materials.

The organic HAP emission rate for the initial compliance period calculated using Equation 3 of this subsection shall be less than or equal to the applicable emission limit for each subcategory in s. NR 465.33(1) or the predominant activity or facility-specific emission limit allowed in s. NR 465.33(1) (c). You shall keep all records as required by s. NR 465.35(3) and (4). As part of the notification of compliance status required by s. NR 465.35(1), you shall identify the coating operations for which you used the emission rate without add-on controls option and submit a statement that the coating operations were in compliance with the emission limits specified in s. NR 465.33(1) during the initial compliance period because the organic HAP emission rate was less than or equal to the applicable emission limit in s. NR 465.33(1), determined according to the procedures in this subsection.

(3) HOW DO I DEMONSTRATE CONTINUOUS COMPLIANCE WITH THE EMISSION LIMITS?

(a) To demonstrate continuous compliance, the organic HAP emission rate for each compliance period, determined according to sub. (2) (a) to (g), shall be less than or equal to the applicable emission limit in s. NR 465.33(1). 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. You shall perform the calculations in sub. (2) (a) to (g) on a monthly basis using data from the previous 12 months of operation. If you are complying with a facility-specific emission limit under s. NR 465.33(1) (c) 2., you shall also perform the calculation using Equation 1 in s. NR 465.33(1) (c) 2. on a monthly basis using the data from the previous 12 months of operation.

(b) If the organic HAP emission rate for any 12-month compliance period exceeded the applicable emission limit in s. NR 465.33(1), this is a deviation from the emission limit for that compliance period and shall be reported as specified in s. NR 465.35(1) (c) 6. and (2) (a) 6.

(c) As part of each semiannual compliance report required by s. NR 465.35(2), you shall identify the coating operations for which you used the emission rate without add-on controls option. If there were no deviations from the emission limits specified in s. NR 465.33(1), you shall submit a statement that the coating operations were in compliance with the emission limits during the reporting period because the organic HAP emission rate for each compliance period was less than or equal to the applicable emission limit in s. NR 465.33(1), determined according to sub. (2) (a) to (g).

(d) You shall maintain records as specified in s. NR 465.35(3) and (4).
