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

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
