NR 440.207(5)(h)(h) For affected facilities subject to sub. (3) (h) 1., 2. or 3. where the owner or operator seeks to demonstrate compliance with the SO2 standards based on fuel supplier certification, the performance test shall consist of the certification, the certification from the fuel supplier, as described under sub. (9) (f) 1., 2. or 3., as applicable.

NR 440.207(5)(i)(i) The owner or operator of an affected facility seeking to demonstrate compliance with the SO2 standards under sub. (3) (c) 2. shall demonstrate the maximum design heat input capacity of the steam generating unit by operating the steam generating unit at this capacity for 24 hours. This demonstration shall be made during the initial performance test, and a subsequent demonstration may be requested at any other time. If the demonstrated 24-hour average firing rate for the affected facility is less than the maximum design heat input capacity stated by the manufacturer of the affected facility, the demonstrated 24-hour average firing rate shall be used to determine the annual capacity factor for the affected facility; otherwise, the maximum design heat input capacity provided by the manufacturer shall be used.

NR 440.207(5)(j)(j) The owner or operator of an affected facility shall use all valid SO2 emissions data in calculating %Ps and Eho under par. (d), (e) or (f), as applicable, whether or not the minimum emissions data requirements under sub. (7) (f) are achieved. All valid emissions data, including valid data collected during periods of startup, shutdown and malfunction shall be used in calculating %Ps or Eho pursuant to par. (d), (e) or (f), as applicable.

NR 440.207(6)(a)(a) The owner or operator of an affected facility subject to the PM standards, opacity standards, or both, under sub. (4) shall conduct an initial performance test as required under s. NR 440.08, and shall conduct subsequent performance tests as requested by the department, to determine compliance with the standards using the following procedures and reference methods. Unless otherwise indicated, these procedures and reference methods are in 40 CFR part 60, Appendix A, which is incorporated by reference in s. NR 440.17.

NR 440.207(6)(a)3.b.b. Method 17 may be used at affected 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 Sections 8.1 and 11.1 of Method 5B may be used in Method 17 only if Method 17 is used in conjunction with a wet scrubber system. Method 17 may not be used in conjunction with a wet scrubber system if the emissions are saturated or laden with water droplets.

NR 440.207(6)(a)4.4. The sampling time for each run shall be at least 120 minutes and the minimum sampling volume shall be 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 440.207(6)(a)5.5. For Method 5 or Method 5B, the temperature of the sample gas in the probe and filter holder shall be monitored and maintained at 160 ± 14°C (320 ± 25°F).

NR 440.207(6)(a)6.6. For determination of PM emissions, an oxygen or carbon dioxide measurement shall be obtained simultaneously with each run of Method 5, Method 5B or Method 17 by traversing the duct at the same sampling location.

NR 440.207(6)(b)(b) The owner or operator of an affected facility seeking to demonstrate compliance with the PM standards under sub. (4) (b) 2. shall demonstrate the maximum design heat input capacity of the steam generating unit by operating the steam generating unit at this capacity for 24 hours. This demonstration shall be made during the initial performance test, and a subsequent demonstration may be requested at any other time. If the demonstrated 24-hour average firing rate for the affected facility is less than the maximum design heat input capacity stated by the manufacturer of the affected facility, the demonstrated 24-hour average firing rate shall be used to the determine annual capacity factor for the affected facility; otherwise, the maximum design heat input capacity provided by the manufacturer shall be used.

NR 440.207(7)(a)(a) Except as provided in pars. (d) and (e), the owner or operator of an affected facility subject to the SO2 emission limits under sub. (3) shall install, calibrate, maintain and operate a CEMS for measuring SO2 concentrations and either oxygen or carbon dioxide concentrations at the outlet of the SO2 control device (or the outlet of the steam generating unit if no SO2 control device is used), and shall record the output of the system. The owner or operator of an affected facility subject to the percent reduction requirements under sub. (3) shall measure SO2 concentrations and either oxygen or carbon dioxide concentrations at both the inlet and outlet of the SO2 control device.

NR 440.207(7)(b)(b) The 1-hour average SO2 emission rates measured by a CEMS shall be expressed in ng/J or lb/million Btu heat input and shall be used to calculate the average emission rates under sub. (3). Each 1-hour average SO2 emission rate shall be based on at least 30 minutes of operation and include at least 2 data points representing 2 15-minute periods. Hourly SO2 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 440.207(7)(c)(c) The procedure under s. NR 440.13 shall be followed for installation, evaluation and operation of the CEMS.

NR 440.207(7)(c)1.1. All CEMS shall be operated in accordance with the applicable procedures under Performance Specifications 1, 2 and 3 of 40 CFR part 60 Appendix B, incorporated by reference in s. NR 440.17.

NR 440.207(7)(c)2.2. Quarterly accuracy determinations and daily calibration drift tests shall be performed in accordance with Procedure 1 of 40 CFR part 60 Appendix F, incorporated by reference in s. NR 440.17.

NR 440.207(7)(c)3.3. For affected facilities subject to the percent reduction requirements under sub. (3), the span value of the SO2 CEMS at the inlet to the SO2 control device shall be 125% of the maximum estimated hourly potential SO2 emission rate of the fuel combusted, and the span value of the SO2 CEMS at the outlet from the SO2 control device shall be 50% of the maximum estimated hourly potential SO2 rate of the fuel combusted.

NR 440.207(7)(c)4.4. For affected facilities that are not subject to the percent reduction requirements of sub. (3), the span value of the SO2 CEMS at the outlet from the SO2 control device, or outlet of the steam generating unit if no SO2 control device is used, shall be 125% of the maximum estimated hourly potential SO2 emission rate of the fuel combusted.

NR 440.207(7)(d)(d) As an alternative to operating a CEMS at the inlet to the SO2 control device, or outlet of the steam generating unit if no SO2 control device is used, as required under par. (a), an owner or operator may elect to determine the average SO2 emission rate by sampling the fuel prior to combustion. As an alternative to operating a CEMS at the outlet from the SO2 control device, or outlet of the steam generating unit if no SO2 control device is used, as required under par. (a), an owner or operator may elect to determine the average SO2 emission rate by using Method 6B. Fuel sampling shall be conducted pursuant to either subd. 1. or 2. Method 6B shall be conducted pursuant to subd. 3.
