NR 440.207(5)(a)(a) Except as provided in pars. (g) and (h) and in s. NR 440.08 (2), performance tests required under s. NR 440.08 shall be conducted following the procedures specified in pars. (b) to (f), as applicable. The cited methods and procedures are in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 440.17. Section NR 440.08 (6) does not apply to this subsection. The 30-day notice required in s. NR 440.08 (4) applies only to the initial performance test unless otherwise specified by the department. NR 440.207(5)(b)(b) The initial performance test required under s. NR 440.08 shall be conducted over 30 consecutive operating days of the steam generating unit. Compliance with the percent reduction requirements and SO2 emission limits under sub. (3) shall be determined using a 30-day average. The first operating day included in the initial performance test shall be scheduled within 30 days after achieving the maximum production rate at which the affected facility will be operated, but not later than 180 days after the initial startup of the facility. The steam generating unit load during the 30-day period does not have to be the maximum design heat input capacity, but shall be representative of future operating conditions. NR 440.207(5)(c)(c) After the initial performance test required under par. (b) and s. NR 440.08, compliance with the percent reduction requirements and SO2 emission limits under sub. (3) is based on the average percent reduction and the average SO2 emission rates for 30 consecutive steam generating unit operating days. A separate performance test is completed at the end of each steam generating unit operating day, and a new 30-day average percent reduction and SO2 emission rate are calculated to show compliance with the standard. NR 440.207(5)(d)(d) If only coal, only oil, or a mixture of coal and oil is combusted in an affected facility, the procedures in Method 19 are used to determine the hourly SO2 emission rate (Eho) and the 30-day average SO2 emission rate (Eao). The hourly averages are obtained from the continuous emission monitoring system (CEMS). Method 19 shall be used to calculate Eao when using daily fuel sampling or Method 6B. NR 440.207(5)(e)(e) If coal, oil, or coal and oil are combusted with other fuels: NR 440.207(5)(e)1.1. An adjusted Eho (Ehoo) is used in equation 19-19 of Method 19 to compute the adjusted Eao (Eaoo). The Ehoo is computed using the following formula: Ehoo = (Eho - Ew(1 - Xk))/Xk
where:
Ehoo is the adjusted Eho, ng/J (lb/million Btu)
Eho is the hourly SO2 emission rate, ng/J (lb/million Btu)
Ew is the SO2 concentration in fuels other than coal and oil combusted in the affected facility, as determined by fuel sampling and analysis procedures in Method 9, ng/J (lb/million Btu). The value Ew for each fuel lot is used for each hourly average during the time that the lot is being combusted. The owner or operator does not have to measure Ew if the owner or operator elects to assume Ew = 0
Xk is the fraction of the total heat input from fuel combustion derived from coal and oil, as determined by applicable procedures in Method 19
NR 440.207(5)(e)2.2. The owner or operator of an affected facility that qualifies under the provisions of sub. (3) (c) or (d), where percent reduction is not required, does not have to measure the parameters Ew or Xk if the owner or operator of the affected facility elects to measure emission rates of the coal or oil using the fuel sampling and analysis procedures under Method 19. NR 440.207(5)(f)(f) Affected facilities subject to the percent reduction requirements under sub. (3) (a) or (b) shall determine compliance with the SO2 emission limits under sub. (3) pursuant to par. (d) or (e), and shall determine compliance with the percent reduction requirements using the following procedures: NR 440.207(5)(f)1.1. If only coal is combusted, the percent of potential SO2 emission rate is computed using the following formula: %Ps = 100 (1 - %Rg/100) (1 - %Rf/100)
where:
%Ps is the percent of potential SO2 emission rate, in percent
%Rg is the SO2 removal efficiency of the control device as determined by Method 19, in percent
%Rf is the SO2 removal efficiency of fuel pretreatment as determined by Method 19, in percent
NR 440.207(5)(f)2.2. If coal, oil, or coal and oil are combusted with other fuels, the same procedures required in subd. 1. are used, except as provided for in the following: NR 440.207(5)(f)2.a.a. To compute the %Ps, an adjusted %Rg (%Rgo) is computed from Eaoo from par. (e) 1. and an adjusted SO2 inlet rate (Eaio) using the following formula: %Rgo = 100 [1.0 - (Eaoo/Eai)]
where:
%Rgo is the adjusted %Rg, in percent
Eaoo is the adjusted Eao, ng/J (lb/million Btu)
Eaio is the adjusted average SO2 inlet rate, ng/J (lb/million Btu)
NR 440.207(5)(f)2.b.b. To compute Eaio, an adjusted hourly SO2 inlet rate (Ehio) is used. The Ehio is computed using the following formula: Ehio = [Ehi - Ew (1 - Xk)]/Xk
