Section NR 465.27 - 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 465.21(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 calculations according to sub. (2) and supporting documentation showing that the organic HAP emission rate for the initial compliance period was equal to or less than the applicable emission limit in s. NR 465.23(1).

(2) HOW DO I DEMONSTRATE INITIAL COMPLIANCE WITH THE EMISSION LIMITATIONS?. 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 of the coating operations in the affected source. You shall use either the compliant material option or the emission rate with add-on controls option for any coating operation or operations in the affected source for which you do not use this option. To demonstrate initial compliance using the emission rate without add-on controls option, the coating operation or operations shall meet the applicable emission limit in s. NR 465.23(1) but not the operating limits or work practice standards in s. NR 465.23(3) and (4), respectively, during the initial compliance period. When calculating the organic HAP emission rate according to this subsection, you may not include any coatings, thinners or cleaning materials used on coating operations for which you use the compliant material option or the emission rate with add-on controls option. You do not need to redetermine the mass of organic HAP in coatings, thinners or cleaning materials that have been reclaimed onsite and reused in the coating operation or operations for which you use the emission rate without add-on controls option. You shall meet all of the following requirements to demonstrate initial compliance with the applicable emission limit in s. NR 465.23(1) for the coating operation or operations:

(a) Determine the mass fraction of organic HAP for each coating, thinner and cleaning material used during the compliance period according to the requirements in s. NR 465.26(2) (a).

(b) Determine the volume fraction of coating solids for each coating used during the compliance period according to the requirements in s. NR 465.26(2) (b).

(c) Determine the density of each coating, thinner and cleaning material used during the compliance period according to the requirements in s. NR 465.26(2) (c).

(d) Determine the volume (liters) of each coating, thinner and cleaning material used during the compliance period by measurement or usage records.

(e)

1. Calculate the mass of organic HAP emissions during the compliance period using the following equations and the procedures in subd. 2. if applicable:

H_e = A + B + C - R_w

C is the total mass of organic HAP in the cleaning materials used during the compliance period, kg, as calculated in Equation 1C

R_w is the total mass of organic HAP in waste materials sent or designated for shipment to a hazardous waste TSDF for treatment or disposal during the compliance period, kg, determined according to subd. 2. You may assign a value of zero to Rw if you do not wish to use this allowance

2. If you choose to account for the mass of organic HAP contained in waste materials sent or designated for shipment to a hazardous waste TSDF in the calculation of the mass of organic HAP emissions using Equation 1, you shall determine it according to the following procedures:

a. You may include in the determination of organic HAP in waste materials only the waste materials that are generated by coating operations for which you use Equation 1 in subd. 1. and that will be treated or disposed of by a facility that is regulated as a TSDF under 40 CFR part 262, 264, 265, or 266 . The TSDF may be either off-site or on-site. You may not include in the determination the organic HAP contained in wastewater.

b. Determine either the amount of waste materials sent to a TSDF during the compliance period or the amount collected and stored during the compliance period and designated for future transport to a TSDF. You may not include in your determination any waste materials sent to a TSDF during a compliance period if you have already included them in the amount collected and stored during that compliance period or a previous compliance period.

c. Determine the total mass of organic HAP contained in the waste materials specified in subd. 2. b.

d. Document your methodology to determine the amount of waste materials and the total mass of organic HAP they contain, as required in s. NR 465.25(3) (h).

e. To the extent that waste manifests include this information, they may be used as part of the documentation of the amount of waste materials and mass of organic HAP contained in them.

(f) Determine the total volume of coating solids used, liters, which is the combined volume of coating solids for all of the coatings used during the compliance period, using the following equation:

V_st is the total volume coating solids used during the compliance period, liters, as calculated using Equation 2 in par. (f)

(h) Ensure that the organic HAP emission rate for the initial compliance period is less than or equal to the applicable emission limit in s. NR 465.23(1). You shall keep all records as required by s. NR 465.25(3) and (4). As part of the notification of compliance status required by s. NR 465.25(1), you shall identify the coating operation or operations for which you used the emission rate without add-on controls option and submit a statement that the coating operation was, or operations were, in compliance with the emission limitations during the initial compliance period because the organic HAP emission rate was less than or equal to the applicable emission limit in s. NR 465.23(1).

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

(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 465.23(1). Each month following the initial compliance period described in sub. (1) is a compliance period.

(b) If the organic HAP emission rate for any compliance period exceeded the applicable emission limit in s. NR 465.23(1), this is a deviation from the emission limitations for that compliance period and shall be reported as specified in s. NR 465.25(1) (b) 6. and (2) (e).

(c) As part of each semiannual compliance report required by s. NR 465.25(2), you shall submit a statement that you were in compliance with the emission limitations 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 465.23(1).

(d) You shall maintain records as specified in s. NR 465.25(3) and (4).
