NR 440.218(7)(b)9.9. Method 23 of 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), shall be used to measure total dioxin/furan emissions. The minimum sample time shall be 4 hours per test run. If the affected facility has selected the toxic equivalency standards for dioxin/furan, under sub. (3), the following procedures shall be used to determine compliance: NR 440.218(7)(b)9.a.a. Measure the concentration of each dioxin/furan tetra- through octa- congener emitted using Method 23. NR 440.218(7)(b)9.b.b. For each dioxin/furan congener measured in accordance with subd. 9. a., multiply the congener concentration by its corresponding toxic equivalency factor specified in Table 2. NR 440.218(7)(b)9.c.c. Sum the products calculated in accordance with subd. 9. b. to obtain the total concentration of dioxin/furan emitted in terms of toxic equivalency. NR 440.218(7)(b)10.10. Method 26 or 26A of 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), shall be used to measure hydrogen chloride emissions. If the affected facility has selected the percentage reduction standards for hydrogen chloride under sub. (3), the percentage reduction in hydrogen chloride emissions (%RHCl) shall be computed using the following formula: where:
%RHCl is the percentage reduction of hydrogen chloride emissions achieved
Ei is the hydrogen chloride emission concentration measured at the control device inlet, corrected to 7% oxygen, dry basis
Eo is the hydrogen chloride emission concentration measured at the control device outlet, corrected to 7% oxygen, dry basis
NR 440.218(7)(b)11.11. Method 29 of 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), shall be used to measure lead, cadmium and mercury emissions. If the affected facility has selected the percentage reduction standards for metals under sub. (3), the percentage reduction in emissions (%Rmetal) shall be computed using the following formula: where:
%Rmetal is the percentage reduction of metal emission of lead, cadmium or mercury achieved
Ei is the metal emission concentration of lead, cadmium or mercury, measured at the control device inlet, corrected to 7% oxygen, dry basis
Eo is the metal emission concentration of lead, cadmium or mercury, measured at the control device outlet, corrected to 7% oxygen, dry basis
NR 440.218(7)(b)12.12. Method 22 of 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), shall be used to determine compliance with the fugitive ash emission limit under sub. (3) (c). The minimum observation time shall be a series of 3 1-hour observations. NR 440.218(7)(c)(c) 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 shall do the following, as applicable: NR 440.218(7)(c)1.1. Determine compliance with the opacity limit by conducting an annual performance test, no more than 12 months following the previous performance test, using the applicable procedures and test methods listed in par. (b). NR 440.218(7)(c)2.2. Determine compliance with the particulate matter, carbon monoxide and hydrogen chloride emission limits by conducting an annual performance test, no more than 12 months following the previous performance test, using the applicable procedures and test methods listed in par. (b). If all 3 performance tests over a 3-year period indicate compliance with the emission limit for a pollutant (particulate matter, carbon monoxide or hydrogen chloride), the owner or operator may forego a performance test for that pollutant for the subsequent 2 years. At a minimum, a performance test for particulate matter, carbon monoxide and hydrogen chloride shall be conducted every third year, no more than 36 months following the previous performance test. If a performance test conducted every third year indicates compliance with the emission limit for a pollutant (particulate matter, carbon monoxide or hydrogen chloride), the owner or operator may forego a performance test for that pollutant for an additional 2 years. If any performance test indicates noncompliance with the respective emission limit, a performance test for that pollutant shall be conducted annually until all annual performance tests over a 3-year period indicate compliance with the emission limit. The use of the bypass stack during a performance test shall invalidate the performance test. NR 440.218(7)(c)3.3. For large HMIWI, determine compliance with the visible emission limits for fugitive emissions from flyash/bottom ash storage and handling by conducting a performance test using Method 22 of 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), on an annual basis, no more than 12 months following the previous performance test.
