§ 63.2171 How do I demonstrate continuous compliance with the emission limitations?

(a) You must demonstrate continuous compliance with each emission limitation in Table 1 to this subpart that applies to you according to the methods specified in Table 4 to this subpart and the applicable procedures of this section.

(b) To demonstrate compliance with emission limitations by using the 98-Percent Option, you must calculate the percentage of within-concentration batches (as defined in § 63.2192) for each 12-month calculation period by following the procedures in this paragraph and paragraphs (e)(1) and (2) of this section. At the end of each calendar month, you must determine the percentage of batches that were in compliance with the applicable maximum concentration in the 12-month calculation period. The total number of batches in the calculation period is the sum of the numbers of batches of each fermentation stage for which emission limitations apply. To determine which batches are in the 12-month calculation period, you must include those batches for which the batch monitoring period ended at or after midnight on the first day of the period and exclude those batches for which the batch monitoring period did not end before midnight on the last day of the period.
