Each 1-hour average sulfur dioxide emission rate shall be based on more than 30 minutes of steam generating unit operation and include at least 2 data points with each representing a 15-minute period. Hourly sulfur dioxide emission rates are not calculated if the affected facility is operated less than 30 minutes in a 1-hour period and are not counted toward determination of a steam generating unit operating day.

NR 440.205(8)(e)3.3. For affected facilities combusting coal or oil, alone or in combination with other fuels, the span value of the sulfur dioxide CEMS at the inlet to the sulfur dioxide control device shall be 125% of the maximum estimated hourly potential sulfur dioxide emissions of the fuel combusted, and the span value of the CEMS at the outlet to the sulfur dioxide control device shall be 50% of the maximum estimated hourly potential sulfur dioxide emissions of the fuel combusted.
NR 440.205(8)(f)(f) The owner or operator of an affected facility that combusts very low sulfur oil is not subject to the emission monitoring requirements of this subsection if the owner or operator obtains fuel receipts as described in sub. (10) (r).
NR 440.205(9)(9)Emission monitoring for particulate matter and nitrogen oxides.
NR 440.205(9)(a)(a) The owner or operator of an affected facility subject to the opacity standard under sub. (4) shall install, calibrate, maintain, and operate a continuous monitoring system for measuring the opacity of emissions discharged to the atmosphere and record the output of the system.
NR 440.205(9)(b)(b) Except as provided under pars. (g), (h) and (i), the owner or operator of an affected facility shall comply with one of the following:
NR 440.205(9)(b)1.1. Install, calibrate, maintain and operate a continuous monitoring system, and record the output of the system, for measuring nitrogen oxides emissions discharged to the atmosphere.
NR 440.205(9)(b)2.2. If the owner or operator has installed a nitrogen oxides emission rate continuous emission monitoring system (CEMS) to meet the requirements of 40 CFR part 75 and is continuing to meet the ongoing requirements of 40 CFR part 75, that CEMS may be used to meet the requirements of this subsection, except that the owner or operator shall also meet the requirements of sub. (10). Data reported to meet the requirements of sub. (10) may not include data substituted using the missing data procedures in 40 CFR part 75, subpart D, nor shall the data have been bias adjusted according to the procedures of 40 CFR part 75.
NR 440.205(9)(c)(c) The continuous monitoring systems required under par. (b) shall be operated and data recorded during all periods of operation of the affected facility except for continuous monitoring system breakdowns and repairs. Data shall be recorded during calibration checks, and zero and span adjustments.
NR 440.205(9)(d)(d) The 1-hour average nitrogen oxides emission rates measured by the continuous nitrogen oxides monitor required by par. (b) and required under s. NR 440.13 shall be expressed in ng/J or lb/million Btu heat input and shall be used to calculate the average emission rates under sub. (5). The 1-hour averages shall be calculated using the data points required under s. NR 440.13 (2). At least 2 data points shall be used to calculate each 1-hour average.
NR 440.205(9)(e)(e) The procedures under s. NR 440.13 shall be followed for installation, evaluation, and operation of the continuous monitoring systems.
NR 440.205(9)(e)1.1. For affected facilities combusting coal, wood or municipal-type solid waste, the span value for a continuous monitoring system for measuring opacity shall be between 60 and 80%.
NR 440.205(9)(e)2.2. For affected facilities combusting coal, oil, or natural gas, the span value for nitrogen oxides is determined as follows:
- See PDF for table PDF
where:
x is the fraction of total heat input derived from natural gas
y is the fraction of total heat input derived from oil
z is the fraction of total heat input derived from coal
NR 440.205(9)(e)3.3. All span values computed under subd. 2. for combusting mixtures of regulated fuels shall be rounded to the nearest 500 PPM.
NR 440.205(9)(f)(f) When nitrogen oxides emission data are not obtained because of continuous monitoring system breakdowns, repairs, calibration checks and zero and span adjustments, emission data will be obtained by using standby monitoring systems, Method 7 or 7A of Appendix A, 40 CFR part 60, incorporated by reference in s. NR 440.17, or other approved reference methods to provide emission data for a minimum of 75% of the operating hours in each steam generating unit operating day, in at least 22 out of 30 successive steam generating unit operating days.
NR 440.205(9)(g)(g) The owner or operator of an affected facility that has a heat input capacity of 73 MW (250 million Btu/hour) or less, and which has an annual capacity factor for residual oil having a nitrogen content of 0.30 weight % or less, natural gas, distillate oil, or any mixture of these fuels, greater than 10% (0.10) shall:
NR 440.205(9)(g)1.1. Comply with the provisions of pars. (b), (c), (d), (e) 2., (e) 3., and (f), or
