40 CFR Appendix Table 1 to Subpart CCCC of Part 63 - Table 1 to Subpart CCCC of Part 63—Emission Limitations

For each fed-batch fermenter producing yeast in the following fermentation stage . . .	98-percent option: You must not exceed the following VOC emission limitation a according to the timeline in Table 7 to this subpart . . .	Average option: You must not exceed the following VOC emission limitation a according to the timeline in Table 7 to this subpart . . .	Batch option: You must not exceed the following VOC emission limitation a according to the timeline in Table 7 to this subpart . . .
Last stage	100 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 stage	200 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 stage	300 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.
