NR 439.07(8)(b)3.3. Method 17, for particulates, in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), may not be used where stack or duct temperatures exceed 320°F.

NR 439.07(8)(b)4.4. Heat input shall be equal to the fuel use rate multiplied by the heat content of the fuel on an as-fired basis. Fuels shall be analyzed for heat content using the procedures in Method 19 in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13).

NR 439.07(8)(b)5.5. Any boiler emission rate in pounds per million Btu heat input shall be determined using the heat input based on fuel use rate. The emission rate may be determined using the F-Factor calculation shown in Method 19 in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), with written approval from the department. If the F-Factor method is used, an ultimate fuel analysis shall be performed. An integrated gas sample, using Method 3, 3A or 3B in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), shall be collected and analyzed for oxygen and carbon dioxide content. Other methods for determining the boiler heat input may be used only if approved, in writing, by the department.

NR 439.07(8)(b)6.6. If cyclonic flow is a possibility at a particulate emission test location, a test for the presence of cyclonic flow shall be performed before the particulate test using the procedures in Method 1 in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13). If cyclonic flow is present, the flow must be straightened before testing can begin unless the source owner or operator demonstrates, to the department’s satisfaction, the acceptability of the location using the alternate procedure to Method 1. If cyclonic flow is not present, testing can proceed.

NR 439.07(8)(b)7.7. Except for sources subject to emission testing requirements in ch. NR 440, the department may require the owner or operator of a source capable of emitting condensible particulate matter, to include an analysis of the back half of the stack sampling train catch in the total particulate catch for any emission test using Method 5, 5A, 5B, 5D, 5E, 5F, 5G, 5H, 5I, or 17, in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13). This procedure and analysis shall be performed using Method 202 in 40 CFR part 51, Appendix M, incorporated by reference in s. NR 484.04 (9).

NR 439.07(8)(c)1.1. When compliance with a sulfur dioxide emission limitation is determined using Method 6 or 6A in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), the test shall consist of 3 repetitions. A repetition shall consist of 2 20-minute sampling periods with each sampling period followed by a 15-minute fresh air purge. The 2 samples shall be analyzed independently. The arithmetic mean of the results of the 2 samples shall be the result of that repetition.

NR 439.07(8)(c)2.2. When compliance with a sulfur dioxide emission limitation is determined using Method 6B in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), the test shall consist of 3 24-hour repetitions with the sampling train operating continuously during each 24-hour repetition.

NR 439.07(8)(c)3.3. When compliance with a sulfur dioxide emission limitation is determined using Method 6C in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), the test shall consist of 3 representative repetitions.

NR 439.07(8)(d)1.1. When compliance with a nitrogen oxide emission limitation is determined using Method 7, 7A or 7B in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), the test shall consist of 3 repetitions. A repetition shall consist of 4 2-liter evacuated sample bottles that are filled, one at a time, with stack gas at 15 minute intervals. The 4 samples shall be analyzed independently. The arithmetic mean of the results of the 4 samples shall be the result of that repetition.

NR 439.07(8)(d)2.2. When compliance with a nitrogen oxide emission limitation is determined using Method 7C, 7D, or 7E in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), the test shall consist of 3 representative repetitions.

NR 439.07(8)(e)(e) Organic compound emissions. When compliance with an organic compound emission limitation is determined using Methods 18, 25, 25A, or 25B in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), the test shall consist of a minimum of 3 representative repetitions.

NR 439.07(8)(f)(f) Visible emissions. When compliance with a visible emission limitation is determined using Method 9 in 40 CFR part 60, Appendix A-4, incorporated by reference in s. NR 484.04 (13), the test shall be performed based on the either of the following time criteria, unless otherwise specified in any applicable regulation, permit or compliance order:

NR 439.07(8)(f)1.1. For a new construction permit, operation permit or a renewal of an operation permit, the minimum total time of observations shall be 60 minutes, consisting of 10 6-minute averages.

NR 439.07(8)(g)(g) Exceptions. With department approval, compliance with pars. (a) to (e) may be determined as the arithmetic mean of 2 representative repetitions if 3 repetitions cannot be used to determine compliance because of any of the following circumstances:

NR 439.07(9)(9) Emission test reporting requirements. The owner or operator of the source tested, including initial certification tests and relative accuracy tests performed under s. NR 439.09, shall submit 2 copies of the emission test report to the department within 60 days after completion of a compliance emission test if no samples were collected by the department witness. If samples were collected by the department, the test report shall be submitted within 30 days after the results from the test samples have been reported to the source owner or operator by the department. If requested, the department may grant an extension of up to 30 days for test report submittal. The failure to include the following information in an emission test report may result in rejection of the test. The emission test report shall include, but need not be limited to, the following information:
