Xk is the fraction of total heat input from fuel combustion derived from coal, oil, or coal and oil, as determined by applicable procedures in Method 19
NR 440.205(6)(c)3.b.b. To compute the percent of potential sulfur dioxide emission rate (%Ps), an adjusted %Rg (%Rgo) is computed from the adjusted Eaoo from subd. 3. a. and an adjusted average sulfur dioxide inlet rate (Eaio) using the following formula: To compute Eai°, an adjusted hourly sulfur dioxide inlet rate (Ehi°) is used. The Ehi° is computed using the following formula: where:
Ehi° is the adjusted hourly sulfur dioxide inlet rate, ng/J (lb/million Btu)
Ehi is the hourly sulfur dioxide inlet rate, ng/J (lb/million Btu)
NR 440.205(6)(c)4.4. The owner or operator of an affected facility subject to subd. 3. does not have to measure parameters Ew or Xk if the owner or operator elects to assume that Xk = 1.0. Owners or operators of affected facilities who assume Xk = 1.0 shall determine %Ps, following the procedures in subd. 2., and sulfur dioxide emissions (Es) shall be considered to be in compliance with sulfur dioxide emission limits under sub. (3). NR 440.205(6)(c)5.5. The owner or operator of an affected facility that qualifies under the provisions of sub. (3) (d) does not have to measure parameters Ew or Xk under subd. 3. if the owner or operator of the affected facility elects to measure sulfur dioxide emission rates of the coal or oil following the fuel sampling and analysis procedures under Method 19. NR 440.205(6)(d)(d) Except as provided in par. (j), the owner or operator of an affected facility that combusts only very low sulfur oil, has an annual capacity factor for oil of 10% (0.10) or less, and is subject to a federally enforceable requirement limiting operation of the affected facility to an annual capacity factor for oil of 10% (0.10) or less shall: NR 440.205(6)(d)1.1. Conduct the initial performance test over 24 consecutive steam generating unit operating hours at full load; NR 440.205(6)(d)2.2. Determine compliance with the standards after the initial performance test based on the arithmetic average of the hourly emissions data during each steam generating unit operating day if a continuous emission monitoring system (CEMS) is used, or based on a daily average if Method 6B, Appendix A of 40 CFR part 60, incorporated by reference in s. NR 440.17, or fuel sampling and analysis procedures under Method 19, Appendix A of 40 CFR part 60, incorporated by reference in s. NR 440.17, are used. NR 440.205(6)(e)(e) The owner or operator of an affected facility subject to sub. (3) (d) 1., shall demonstrate the maximum design capacity of the steam generating unit by operating the facility at maximum capacity for 24 hours. This demonstration will be made during the initial performance test and a subsequent demonstration may be requested at any other time. If the 24-hour average firing rate for the affected facility is less than the maximum design capacity provided by the manufacturer of the affected facility, the 24-hour average firing rate shall be used to determine the capacity utilization rate for the affected facility, otherwise the maximum design capacity provided by the manufacturer shall be used. NR 440.205(6)(f)(f) For the initial performance test required under s. NR 440.08, compliance with the sulfur dioxide emission limits and percent reduction requirements under sub. (3) is based on the average emission rates and the average percent reduction for sulfur dioxide for the first 30 consecutive steam generating unit operating days, except as provided under par. (d). The initial performance test is the only test for which at least 30 days prior notice is required unless otherwise specified by the department. The initial performance test is to be scheduled so that the first steam generating unit operating day of the 30 successive steam generating unit operating days is completed within 30 days after achieving the maximum production rate at which the affected facility will be operated, but not later than 180 days after initial startup of the facility. The boiler load during the 30-day period does not have to be the maximum design load, but shall be representative of future operating conditions and include at least one 24-hour period at full load. NR 440.205(6)(g)(g) After the initial performance test required under s. NR 440.08, compliance with the sulfur dioxide emission limits and percent reduction requirements under sub. (3) is based on the average emission rates and the average percent reduction for sulfur dioxide for 30 successive steam generating unit operating days, except as provided under par. (d). A separate performance test shall be completed at the end of each steam generating unit operating day after the initial performance test, and a new 30-day average emission rate and percent reduction for sulfur dioxide shall be calculated to show compliance with the standard. NR 440.205(6)(h)(h) Except as provided under par. (i), the owner or operator of an affected facility shall use all valid sulfur dioxide emissions data in calculating %Ps and Eho under par. (c), whether or not the minimum emissions data requirements under sub. (7) are achieved. All valid emissions data, including valid sulfur dioxides emission data collected during periods of startup, shutdown and malfunctions, shall be used in calculating %Ps and Eho pursuant to par. (c). NR 440.205(6)(i)(i) During periods of malfunction or maintenance of the sulfur dioxide control systems when oil is combusted as provided under sub. (3) (i), emission data are not used to calculate %Ps or Es under sub. (3) (a), (b) or (c). However, the emissions data are used to determine compliance with the emission limit under sub. (3) (i). NR 440.205(6)(j)(j) The owner or operator of an affected facility that combusts very low sulfur oil is not subject to the compliance and performance testing requirements of this subsection if the owner or operator obtains fuel receipts as described in sub. (10) (r). NR 440.205(7)(7) Compliance and performance test methods and procedures for particulate matter and nitrogen oxides. NR 440.205(7)(a)(a) The particulate matter emission standards and opacity limits under sub. (4) apply at all times except during periods of startup, shutdown, or malfunction. The nitrogen oxides emission standards under sub. (5) apply at all times. 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).
