(6).

NR 439.095(5)(e)(e) Yeast manufacturing plants. The owner or operator of any yeast manufacturing facility subject to s. NR 424.05 shall install, calibrate, maintain and operate a continuous monitoring system for the measurement of VOCs which meets the performance specifications of the department’s approval issued under sub. (1) for each fermenter which does not use add-on control equipment to meet the emission limitations of s. NR 424.05 (2) (a).

NR 439.095(5)(f)(f) Phase I and phase II affected units. The owner or operator of any phase I or phase II affected unit shall install, calibrate, maintain and operate a continuous monitoring system for the measurement of sulfur dioxide, nitrogen oxides, carbon dioxide, stack flow rate and opacity which meets the performance specifications in sub. (6) for each affected unit, or as approved by the department, for a combination of affected units that share a common stack.

NR 439.095(5)(g)(g) Other steam generating units sharing a common stack. The owner or operator of a combination of steam generating units not regulated under par. (f) that share a common stack or duct may, with department approval, install, calibrate, maintain and operate a single continuous monitoring system for the measurement of stack flow rate, opacity, sulfur dioxide, nitrogen oxides, total reduced sulfur, carbon dioxide, VOCs and hazardous air contaminants that meets the performance specifications in sub. (6).

NR 439.095(6)(6) Performance specifications. The owner or operator of monitoring equipment installed to comply with this section shall install, calibrate, maintain and operate the continuous emission monitor in accordance with the performance specifications in 40 CFR part 60, Appendix B or, for affected units, the performance specifications in 40 CFR part 75, Appendices A to I, incorporated by reference in s. NR 484.04 (21) and (27), and the requirements in s. NR 439.09. The owner or operator of the source shall submit a quality control and quality assurance plan for approval by the department. The monitor shall follow the plan, as approved by the department.
