Last stage100 ppmv (measured as propane) for BAVOC for at least 98 percent of all batches in each 12-month calculation period described in § 63.2171(b) and (e)95 ppmv (measured as propane) for the average BAVOC of all batches in this stage in each 12-month calculation period described in § 63.2171(c) and (e)100 ppmv (measured as propane) for BAVOC for each batch.
Second-to-last stage200 ppmv (measured as propane) for BAVOC for at least 98 percent of all batches in each 12-month calculation period described in § 63.2171(b) and (e)190 ppmv (measured as propane) for the average BAVOC of all batches in this stage in each 12-month calculation period described in § 63.2171(c) and (e)200 ppmv (measured as propane) for BAVOC for each batch.
Third-to-last stage300 ppmv (measured as propane) for BAVOC for at least 98 percent of all batches in each 12-month calculation period described in § 63.2171(b) and (e)285 ppmv (measured as propane) for the average BAVOC of all batches in this stage in each 12-month calculation period described in § 63.2171(c) and (e)300 ppmv (measured as propane) for BAVOC for each batch.
a The emission limitation does not apply during the production of specialty yeast.
