NR 465.28(2)(j) (j) Demonstrate initial compliance with the emission limit, by ensuring that the organic HAP emission rate calculated using Equation 4 in par. (i), is less than or equal to the applicable emission limit in s. NR 465.25 (3). 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), identify the coating operation or operations for which you used the emission rate with add-on controls option and submit a statement that the coating operation or operations was or 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), and you achieved the operating limits and the work practice standards required by s. NR 465.23 (3) and (4) respectively.
