NR 440.76(9)(i)2.2. You shall use section 4.3 of Method 19 in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), to calculate the daily geometric average concentrations of sulfur dioxide emissions. If you are monitoring the percent reduction of sulfur dioxide, use section 5.4 of Method 19 to determine the daily geometric average percent reduction of potential sulfur dioxide emissions.

NR 440.76(9)(i)3.3. If you operate a Class I municipal waste combustion unit, you shall use section 4.1 of Method 19 to calculate the daily arithmetic average for concentrations of nitrogen oxides.

NR 440.76(9)(i)4.4. You shall use section 4.1 of Method 19 to calculate the 4-hour or 24-hour daily block averages, as applicable, for concentrations of carbon monoxide.

NR 440.76(9)(j)1.1. You shall install, calibrate, maintain and operate a continuous opacity monitoring system.

NR 440.76(9)(j)2.2. You shall install, evaluate and operate each continuous opacity monitoring system according to s. NR 440.13.

NR 440.76(9)(j)3.3. You shall complete an initial evaluation of your continuous opacity monitoring system according to Performance Specification 1 in 40 CFR part 60, Appendix B, incorporated by reference in s. NR 440.17 (1). You shall complete the evaluation within 60 days after your municipal waste combustion unit reaches the maximum load level at which it will operate, but no more than 180 days after its initial startup.

NR 440.76(9)(j)4.4. You shall complete each annual evaluation of your continuous opacity monitoring system no more than 13 months after the previous evaluation.

NR 440.76(9)(j)5.5. You shall use tests conducted according to Method 9 in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), as specified in sub. (10) (d), to determine compliance with the opacity limit in Table 1 of this section.

NR 440.76(9)(k)(k) What additional requirements must I meet for the operation of my continuous emission monitoring systems and continuous opacity monitoring system? You shall use the required span values and applicable performance specifications in Table 4 of this section.

NR 440.76(9)(L)(L) What must I do if any of my continuous emission monitoring systems are temporarily unavailable to meet the data collection requirements? You shall refer to Table 4 of this section. It shows alternate methods for collecting data when systems malfunction or when repairs, calibration checks or zero and span checks keep you from collecting the minimum amount of data.

NR 440.76(10)(a)(a) What types of stack tests must I conduct? You shall conduct initial and annual stack tests to measure the emission levels of dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride and fugitive ash.

NR 440.76(10)(b)(b) How are the stack test data used? You shall use results of stack tests for dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride and fugitive ash to demonstrate compliance with the emission limits in Table 1 of this section. To demonstrate compliance for carbon monoxide, nitrogen oxides and sulfur dioxide, see sub. (9) (c).

NR 440.76(10)(c)1.1. You shall conduct initial stack tests for the pollutants listed in par. (a) within 60 days after your municipal waste combustion unit reaches the maximum load level at which it will operate, but no later than 180 days after its initial startup.

NR 440.76(10)(c)2.2. You shall conduct annual stack tests for the same pollutants after the initial stack test. You shall conduct each annual stack test no later than 13 months after the previous stack test.

NR 440.76(10)(d)1.1. You shall follow Table 5 of this section to establish the sampling location and to determine pollutant concentrations, number of traverse points, individual test methods, and other specific testing requirements for the different pollutants.

NR 440.76(10)(d)2.2. You shall make sure that stack tests for all the pollutants consist of at least 3 test runs, as specified in s. NR 440.08. You shall use the average of the pollutant emission concentrations from the 3 test runs to determine compliance with the emission limits in Table 1 of this section.

NR 440.76(10)(d)3.3. You shall obtain an oxygen or carbon dioxide measurement at the same time as your pollutant measurements to determine diluent gas levels, as specified in sub. (9) (b).

NR 440.76(10)(d)4.4. You shall use the equations in sub. (15) (a) to (c) to calculate emission levels at 7% oxygen, or an equivalent carbon dioxide basis, the percent reduction in potential hydrogen chloride emissions, and the percent reduction for mercury emissions. The individual test methods in Table 5 of this section shall be used for other required equations.

NR 440.76(10)(d)5.5. You may apply to the department under s. NR 440.08 (2) for approval to use a reference method with minor changes in methodology, to use a shorter sampling time or smaller sampling volume or for a waiver of the requirement for a performance test because you have demonstrated by other means that you are in compliance. You may apply to the administrator as allowed under s. NR 440.08 (2) for approval to use an equivalent method or an alternative method the results of which the administrator has determined are adequate for demonstrating compliance.

NR 440.76(10)(e)1.1. You may test less often than required under par. (c) 2. if you own or operate a Class II municipal waste combustion unit and if all stack tests for a given pollutant over 3 consecutive years show you comply with the emission limit. In that case, you are not required to conduct a stack test for that pollutant for the next 2 years. However, you shall conduct another stack test within 36 months of the anniversary date of the third consecutive stack test that shows you comply with the emission limit. Thereafter, you shall perform stack tests every 3rd year but no later than 36 months following the previous stack tests. If a stack test shows noncompliance with an emission limit, you shall conduct annual stack tests for that pollutant until all stack tests over 3 consecutive years show compliance with the emission limit for that pollutant. The provision applies to all pollutants subject to stack testing requirements: dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride and fugitive ash.

NR 440.76(10)(e)2.2. You may test less often for dioxins/furans emissions if you own or operate a municipal waste combustion plant that meets the following 2 conditions. First, you have multiple municipal waste combustion units onsite that are subject to this section. Second, all those municipal waste combustion units have demonstrated levels of dioxins/furans emissions less than or equal to 7 nanograms per dry standard cubic meter, total mass, for 2 consecutive years. In that case, you may choose to conduct annual stack tests on only one municipal waste combustion unit per year at your plant. This provision only applies to stack testing for dioxins/furans emissions and is subject to the following 3 conditions:

NR 440.76(10)(e)2.a.a. You shall conduct the stack test no more than 13 months following a stack test on any municipal waste combustion unit subject to this section at your plant. Each year, you shall test a different municipal waste combustion unit subject to this section and shall test all municipal waste combustion units subject to this section in a sequence that you determine. Once you determine a testing sequence, it may not be changed without approval by the department.

NR 440.76(10)(e)2.b.b. If each annual stack test shows levels of dioxins/furans emissions less than or equal to 7 nanograms per dry standard cubic meter, total mass, you may continue stack tests on only one municipal waste combustion unit subject to this section per year.
