NR 424.05(1)(a)(a) This section applies to any yeast manufacturing facility which has maximum theoretical emissions of VOCs from the facility greater than or equal to one of the following: NR 424.05(1)(a)1.1. 25 tons per year for a facility located in the county of Kenosha, Milwaukee, Ozaukee, Racine, Washington or Waukesha. NR 424.05(1)(a)2.2. 100 tons per year for a facility located in the county of Kewaunee, Manitowoc or Sheboygan. NR 424.05(1)(b)(b) Any facility that becomes or is currently subject to this section by exceeding the applicability thresholds in par. (a) shall remain subject to this section even if its emissions later fall below the applicability threshold. NR 424.05(2)(a)(a) Except as provided in pars. (b) and (c), no owner or operator of a yeast manufacturing facility may cause, allow or permit the average concentration of VOCs in the exhaust gas stream from a fermenter over the duration of a fermentation batch to exceed the levels in subds. 1. to 3. These levels are on a saturated water basis and are based on total VOCs expressed as propane. NR 424.05(2)(b)(b) The emission limitations of par. (a) do not apply to the emissions resulting from the fermentation of any yeast variety which comprises less than 1% by weight of the facility’s total annual liquid yeast production. NR 424.05(2)(c)(c) Compliance with the emission limitations in par. (a) shall be achieved for at least 98% of all fermentation batches subject to the emission limitations in par. (a) over any 12 consecutive month period. NR 424.05(3)(3) Compliance deadlines. Compliance shall be achieved for each fermenter subject to the emission limitations of sub. (2) (a) by: NR 424.05(3)(a)(a) May 31, 1995 for each fermenter for which compliance is achieved through methods other than installation of emission control equipment. NR 424.05(3)(b)(b) November 30, 1995 for each fermenter for which compliance is achieved through the installation of emission control equipment. NR 424.05(4)(a)(a) Notification. The owner or operator of any yeast manufacturing facility subject to the compliance deadline in sub. (3) (b) for any fermenter, shall submit a notification to the department no later than May 31, 1995, which contains the following information, at a minimum: NR 424.05(4)(a)4.4. Whether add-on control equipment will be used to achieve compliance with sub. (2) (a) for each fermenter. NR 424.05(4)(b)(b) Initial compliance certification. The owner or operator of any yeast manufacturing facility to which this section applies shall, by the applicable compliance deadline in sub. (3), submit a certification for each fermenter that the fermenter is in compliance with the applicable emission limitation, as demonstrated by the continuous emission monitoring required under sub. (5) (a) for fermenters meeting the deadline in sub. (3) (a) and as demonstrated by the compliance emission testing required under sub. (5) (b) for fermenters meeting the deadline in sub. (3) (b). NR 424.05(5)(a)(a) The owner or operator of a yeast manufacturing facility shall, for each fermenter for which compliance with the emission limitations of sub. (2) (a) is achieved through methods other than emission control equipment, install, calibrate, maintain and operate a continuous emission monitor in accordance with ss. NR 439.09 and 439.095 in order to determine compliance with the emission limitations of sub. (2) (a). NR 424.05(5)(b)(b) The owner or operator of a yeast manufacturing facility shall, for each fermenter for which compliance with the emission limitations of sub. (2) (a) is achieved through use of emission control equipment, comply with the requirements of ss. NR 439.055, 439.06, 439.07 and 439.075. Compliance emission testing under this paragraph shall be conducted at least once every 24 months. Each biennial test shall be performed within 90 days of the anniversary date of the test conducted to certify compliance as required under sub. (4) (b). NR 424.05(5)(c)(c) Testing under pars. (a) and (b) shall be conducted at a point in the exhaust gas stream prior to the introduction of any dilution air. Dilution air, for purposes of this paragraph, is considered to be any air not needed to control the fermentation process. NR 424.05(6)(6) Recordkeeping. In addition to meeting the recordkeeping requirements of s. NR 439.04 (1) to (3), the owner or operator of a facility subject to this section shall: NR 424.05(6)(a)2.2. Details of all routine and non-routine maintenance performed on all control devices and monitoring equipment including dates and duration of any outages. NR 424.05(6)(a)3.3. The fermentation cycle for which a fermenter is being used, recorded as either trade, first generation or stock. NR 424.05(6)(b)1.1. The pounds of liquid yeast produced each year for each yeast variety. NR 424.05(6)(b)3.3. The weight percent that each yeast variety represents of the facility’s total annual liquid yeast production. NR 424.05(6)(b)5.5. For each fermentation batch subject to an emission limitation in sub. (2) (a), the average concentration of VOC in the exhaust gas stream over the duration of the fermentation batch. NR 424.05(6)(b)6.6. The number of fermentation batches subject to an emission limitation in sub. (2) (a) completed during each month. NR 424.05(6)(b)7.7. The percent of all completed fermentation batches in compliance with the applicable emission limitation in sub. (2) (a) over the previous 12 consecutive month period. NR 424.05 NoteNote: ‘‘Maximum theoretical emissions” has the meaning given in s. NR 419.02 (11). NR 424.05 HistoryHistory: Cr. Register, June, 1994, No. 462, eff. 7-1-94; am.
