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

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

NR 440.205(9)(g)2. 2. Monitor steam generating unit operating conditions and predict nitrogen oxides emission rates as specified in a plan submitted pursuant to sub. (10) (c).

NR 440.205(9)(h) (h) The owner or operator of a duct burner, as described in sub. (2) (j), which is subject to the NOx standards of sub. (5) (a) 4. or (L), is not required to install or operate a continuous emissions monitoring system to measure NOx emissions.

NR 440.205(9)(i) (i) The owner or operator of an affected facility described under sub. (5) (j) or (k) is not required to install or operate a continuous monitoring system for measuring nitrogen oxide emissions.
