Terms used in this subpart are defined in the Clean Air Act, in 40 CFR 63.2, the General Provisions of this part, and in this section as follows:
Batch means a single fermentation cycle in a single fermentation vessel (fermenter).
Batch monitoring period means the period that begins at the later of either the start of aeration or the addition of yeast to the fermenter; the period ends at the earlier of either the end of aeration or the point at which the yeast has begun being emptied from the fermenter.
Brew means the mixture of yeast and additives in the fermenter.
Brew ethanol means the ethanol in fermenter liquid.
Brew ethanol monitor means the monitoring system that you use to measure brew ethanol to demonstrate compliance with this subpart. The monitoring system includes a resistance element used as an ethanol sensor, with the measured resistance proportional to the concentration of ethanol in the brew.
Brew-to-exhaust correlation means the correlation between the concentration of ethanol in the brew and the concentration of VOC in the fermenter exhaust. This correlation is specific to each fed-batch fermentation stage and is established while manufacturing the product that comprises the largest percentage (by mass) of average annual production.
Emission limitation means any emission limit or operating limit.
Fed-batch means the yeast is fed carbohydrates and additives during fermentation in the vessel. In contrast, carbohydrates and additives are added to ``set-batch'' fermenters only at the start of the batch.
1-hour period means any 60-minute period commencing on the minute at which the batch monitoring period begins.
Product means the yeast resulting from the final stage in a production run. Products are distinguished by yeast species, strain, and variety.
Responsible official means responsible official as defined in 40 CFR 70.2.
Specialty yeast includes but is not limited to yeast produced for use in wine, champagne, whiskey, and beer.
Within-concentration batch means a batch for which the average VOC concentration is not higher than the maximum concentration that is allowed as part of the applicable emission limitation.
Sec. Table 1 to Subpart CCCC of Part 63--Emission Limitations
As stated in Sec. 63.2140, you must comply with the emission limitations in the following table: ------------------------------------------------------------------------
For each fed-batch fermenter producing
yeast in the following fermentation You must meet the following
stage . . . emission limitation . . .------------------------------------------------------------------------Last stage (Trade); or Second-to-last a. For at least 98 percent of
stage (First Generation); or Third-to- all batches (sum of batches

third-to-last stages) in each
12-month calculation period
described in Sec.
63.2171(b), the VOC
concentration in the fermenter
exhaust does not exceed the
applicable maximum
concentration (100 ppmv for
last stage, 200 ppmv for
second-to-last stage, or 300
ppmv for third-to-last stage),
measured as propane, and
averaged over the duration of
a batch.
b. The emission limitation does
not apply during the
production of specialty yeast.------------------------------------------------------------------------
Sec. Table 2 to Subpart CCCC of Part 63--Requirements for Performance
Tests
As stated in Sec. 63.2161, if you demonstrate compliance by monitoring brew ethanol, you must comply with the requirements for performance tests in the following table:

Sec. Table 3 to Subpart CCCC of Part 63--Initial Compliance With
Emission Limitations
As stated in Sec. 63.2165 (if you monitor fermenter exhaust) and Sec. 63.2166 (if you monitor brew ethanol), you must comply with the requirements to demonstrate initial compliance with the applicable emission limitations in the following table: ------------------------------------------------------------------------
