NR 440.205(7)(b)(b) Compliance with the particulate matter emission standards under sub. (4) shall be determined through performance testing as described in par. (d). NR 440.205(7)(c)(c) Compliance with the nitrogen oxides emission standards under sub. (5) shall be determined through performance testing under par. (e) or (f), or under pars. (g) and (h), as applicable. NR 440.205(7)(d)(d) To determine compliance with the standards for particulate matter emission limits and opacity limits under sub. (4), the owner or operator of an affected facility shall conduct an initial performance test as required under s. NR 440.08 using the following procedures and reference methods. These reference methods and procedures are in 40 CFR part 60, Appendix A, which is incorporated by reference in s. NR 440.17. NR 440.205(7)(d)1.1. Method 3B is used for gas analysis when applying Method 5 or Method 17. NR 440.205(7)(d)2.2. Method 5, Method 5B, or Method 17 shall be used to measure the concentration of particulate matter as follows: NR 440.205(7)(d)2.a.a. Method 5 shall be used at affected facilities without wet flue gas desulfurization (FGD) systems; and NR 440.205(7)(d)2.b.b. Method 17 may be used at facilities with or without wet scrubber systems provided the stack gas temperature does not exceed a temperature of 160°C (320°F). The procedures of ss. 2.1 and 2.3 of Method 5B may be used in Method 17 only if it is used after a wet FGD system. Do not use Method 17 after wet FGD systems if the effluent is saturated or laden with water droplets. NR 440.205(7)(d)3.3. Method 1 is used to select the sampling site and the number of traverse sampling points. The sampling time for each run shall be at least 120 minutes and the minimum sampling volume is 1.7 dscm (60 dscf) except that smaller sampling times or volumes may be approved by the department when necessitated by process variables or other factors. NR 440.205(7)(d)4.4. For Method 5, the temperature of the sample gas in the probe and filter holder is monitored and is maintained at 160 ± 14°C (320 ± 25°F). NR 440.205(7)(d)5.5. For determination of particulate emissions, the oxygen or carbon dioxide sample is obtained simultaneously with each run of Method 5, Method 5B or Method 17 by traversing the duct at the sampling location. NR 440.205(7)(d)6.6. For each run using Method 5, Method 5B or Method 17, the emission rate expressed in nanograms per joule heat input is determined using: NR 440.205(7)(d)6.a.a. The oxygen or carbon dioxide measurements and particulate matter measurements obtained under this subsection, NR 440.205(7)(e)(e) To determine compliance with the emission limits for nitrogen oxides required under sub. (5), the owner or operator of an affected facility shall conduct the performance test as required under s. NR 440.08 using the continuous system for monitoring nitrogen oxides under sub. (9). NR 440.205(7)(e)1.1. For the initial compliance test, nitrogen oxides from the steam generating unit shall be monitored for 30 successive steam generating unit operating days and the 30-day average emission rate is used to determine compliance with the nitrogen oxides emission standards under sub. (5). The 30-day average emission rate is calculated as the average of all hourly emissions data recorded by the monitoring system during the 30-day test period. NR 440.205(7)(e)2.2. Following the date on which the initial performance test is completed or is required to be completed under s. NR 440.08, whichever date comes first, the owner or operator of an affected facility which combusts coal or which combusts residual oil having a nitrogen content greater than 0.30 weight % shall determine compliance with the nitrogen oxides emission standards under sub. (5) on a continuous basis through the use of a 30-day rolling average emission rate. A new 30-day rolling average emission rate is calculated each steam generating unit operating day as the average of all of the hourly nitrogen oxides emission data for the preceding 30 steam generating unit operating days. NR 440.205(7)(e)3.3. Following the date on which the initial performance test is completed or is required to be completed under s. NR 440.08, whichever date comes first, the owner or operator of an affected facility which has a heat input capacity greater than 73 MW (250 million Btu/hour) and which combusts natural gas, distillate oil, or residual oil having a nitrogen content of 0.30 weight % or less shall determine compliance with the nitrogen oxides standards under sub. (5) on a continuous basis through the use of a 30-day rolling average emission rate. A new 30-day rolling average emission rate is calculated each steam generating unit operating day as the average of all of the hourly nitrogen oxides emission data for the preceding 30 steam generating unit operating days. NR 440.205(7)(e)4.4. Following the date on which the initial performance test is completed or required to be completed under s. NR 440.08, whichever date comes first, the owner or operator of an affected facility which has a heat input capacity of 73 MW (250 million Btu/hour) or less and which combusts natural gas, distillate oil, or residual oil having a nitrogen content of 0.30 weight % or less shall, upon request, determine compliance with the nitrogen oxides standards under sub. (5) through the use of a 30-day performance test. During periods when performance tests are not requested, nitrogen oxides emissions data collected pursuant to sub. (9) (g) 1. or 2. are used to calculate a 30-day rolling average emission rate on a daily basis and used to prepare excess emission reports, but will not be used to determine compliance with the nitrogen oxides emission standards. A new 30-day rolling average emission rate is calculated each steam generating unit operating day as the average of all of the hourly nitrogen oxides emission data for the preceding 30 steam generating unit operating days. NR 440.205(7)(e)5.5. If the owner or operator of an affected facility which combusts residual oil does not sample and analyze the residual oil for nitrogen content, as specified in sub. (10) (e), the requirements of subd. 2. apply and the provisions of subd. 4. are inapplicable. NR 440.205(7)(f)(f) To determine compliance with the emission limit for NOx required by sub. (5) (a) 4. or (L) for duct burners used in combined cycle systems, either of the procedures described in subd. 1. or 2. may be used: NR 440.205(7)(f)1.1. The owner or operator of an affected facility shall conduct the performance test required under s. NR 440.08 as follows: NR 440.205(7)(f)1.a.a. The emissions rate (E) of NOx shall be computed using Equation 1 of this section: E = Esg + (Hg/Hb)(Esg - Eg) Equation 1
where:
E is the emissions rate of NOx from the duct burner, ng/J (lb/million Btu) heat input
Esg is the combined effluent emissions rate, in ng/J (lb/million Btu) heat input using appropriate F-Factor as described in Method 19
