NR 428.07(2)(b)(b) NOx emissions units subject to the requirements of this subchapter that commence operation on or after February 1, 2001 shall comply with the requirements of this subchapter by the later of the following dates: NR 428.07(2)(c)(c) However, if the applicable deadline under par. (b) does not occur during an ozone season, the deadline for compliance with the requirements of this subchapter becomes the May 1 immediately following the date determined in accordance with par. (b). NR 428.07(2)(d)1.1. An NOx emissions unit with a new stack or flue for which construction is completed after the applicable deadline under par. (a), (b) or (c) shall comply with the requirements of this subchapter 90 days after the date on which emissions first exit through the new stack or flue. NR 428.07(2)(d)2.2. However, if the unit reports on an ozone season basis and the applicable deadline under subd. 1. does not occur during the ozone season, the deadline for compliance with the requirements of this subchapter becomes the May 1 immediately following the date determined in accordance with subd. 1. NR 428.07(3)(3) Reporting data prior to initial certification. The owner or operator of an NOx emissions unit under sub. (2) (b) or (c) shall determine, record and report NOx emissions, heat input, if required for purposes of compliance, and any other values required to determine NOx emissions, for example NOx emission rate and heat input or NOx concentration and stack flow, using the provisions of 40 CFR 75.70(g), from the date and hour that the unit starts operating until all required certification tests are successfully completed. NR 428.07(4)(a)(a) No owner or operator of an NOx emissions unit may use any alternative monitoring system, alternative reference method or any other alternative for the required continuous emission monitoring system without having obtained prior written approval in accordance with s. NR 428.10. NR 428.07(4)(b)(b) No owner or operator of an NOx emissions unit may operate the unit so as to emit NOx without accounting for all NOx emissions in accordance with the applicable provisions of this subchapter. NR 428.07(4)(c)(c) No owner or operator of an NOx emissions unit may disrupt the continuous emission monitoring system, any portion thereof, or any other approved emission monitoring method, and thereby avoid monitoring and recording NOx emissions, except for periods of recertification or periods when calibration, quality assurance testing or maintenance is performed in accordance with the applicable provisions of this subchapter. NR 428.07(4)(d)(d) No owner or operator of an NOx emissions unit may retire or permanently discontinue use of the continuous emission monitoring system, any component thereof or any other approved emission monitoring system under this subchapter, except under one of the following circumstances: NR 428.07(4)(d)1.1. The unit is within a period during which it is covered by a retired unit exemption under s. NR 409.05 that is in effect. NR 428.07(4)(d)2.2. The owner or operator is monitoring emissions from the unit with another certified monitoring system approved, in accordance with the applicable provisions of this subchapter, by the department for use at that unit that provides emission data for the same pollutant or data for the same parameter as the retired or discontinued monitoring system.

NR 428.08(1)(a)(a) Coal-fired units. The owner or operator of a coal-fired boiler shall do one of the following: NR 428.08(1)(a)1.1. Meet the general operating requirements in 40 CFR 75.10 for an NOx-diluent continuous emission monitoring system, consisting of an NOx pollutant concentration monitor, an O2- or CO2-diluent gas monitor and a data acquisition and handling system, to measure NOx emission rate, and for a flow monitoring system and an O2- or CO2-diluent gas monitor to measure heat input, except as provided in accordance with subpart E of 40 CFR part 75. NR 428.08(1)(a)2.2. Meet the general operating requirements in 40 CFR 75.10 for an NOx concentration monitoring system, consisting of an NOx pollutant concentration monitor and a data acquisition and handling system, to measure NOx concentration and for a flow monitoring system. In addition, if heat input is required to be reported under this chapter, the owner or operator also shall meet the general operating requirements for a flow monitoring system and an O2- or CO2-diluent gas monitor to measure heat input, or, if applicable, use the procedures in Appendix D to 40 CFR part 75, incorporated by reference in s. NR 484.04 (27). These requirements shall be met, except as provided in subpart E of 40 CFR part 75. NR 428.08(1)(b)(b) Moisture correction. If a correction for the stack gas moisture content is needed to properly calculate the NOx emission rate in pounds per million Btu, i.e., if the NOx pollutant concentration monitor measures on a different moisture basis from the diluent monitor, or NOx mass emissions in tons, i.e., if the NOx concentration monitoring system or diluent monitor measures on a different moisture basis from the flow rate monitor, the owner or operator of a boiler shall account for the moisture content of the flue gas on a continuous basis in accordance with 40 CFR 75.11(b) except that the term “SO2” shall be replaced by the term “NOx”.
